If you wish to use the original Makefile with no configuration, you can instead use: make -f Makefile.classic On a windows box, use one of the Makefiles in the win/ subdirectory, according to your compiler and environment. If you have MinGW or MinGW-w64 installed on your system (Msys or Cygwin, or as cross-compile environment on Linux or Darwin), then consider: make -f win/Makefile.mingw If you have VC++ installed on your system, then consider: cd win; nmake /f Makefile.msc If you have trouble, or you want to do something fancy, just look at Makefile.classic. There are 6 configuration options that are all well commented. Instead of editing the Makefile.classic, consider copying Makefile.classic to an alternative name such as "GNUMakefile", "BSDMakefile", or "makefile" and editing the copy. BUILDING OUTSIDE THE SOURCE TREE An out of source build is pretty easy: 1. Make and change to a new directory to do the builds in. 2. Run the "configure" script from this directory. 3. Type: "make" For example: mkdir build cd build ../configure make This will now keep all generates files separate from the maintained source code. -------------------------------------------------------------------------- Here are some notes on what is happening behind the scenes: * The configure script (if used) examines the options given and runs various tests with the C compiler to create Makefile from the Makefile.in template as well as autoconfig.h * The Makefile just sets up a few macros and then invokes the real makefile in src/main.mk. The src/main.mk makefile is automatically generated by a TCL script found at src/makemake.tcl. Do not edit src/main.mk directly. Update src/makemake.tcl and then rerun it. * The *.h header files are automatically generated using a program called "makeheaders". Source code to the makeheaders program is found in src/makeheaders.c. Documentation is found in src/makeheaders.html. * Most *.c source files are preprocessed using a program called "translate". The sources to translate are found in src/translate.c. A header comment in src/translate.c explains in detail what it does. * The src/mkindex.c program generates some C code that implements static lookup tables. See the header comment in the source code for details on what it does. Additional information on the build process is available from http://www.fossil-scm.org/fossil/doc/trunk/www/makefile.wiki |

Fossil was originally designed to support the [SQLite](https://sqlite.org) project but has been adopted by many other projects as well. Fossil is self-hosting at <https://fossil-scm.org>. If you are reading this on GitHub, then you are looking at a Git mirror of the self-hosting Fossil repository. The purpose of that mirror is to test and exercise Fossil's ability to export a Git mirror. Nobody much uses the GitHub mirror, except to verify that the mirror logic works. If you want to know more about Fossil, visit the official self-hosting site linked above. |

This is only intended only for Fossil/JSON developers/tinkerers: First, copy cgi-bin/fossil-json.cgi.example to cgi-bin/fossil-json.cgi. Edit it and correct the paths to the fossil binary and the repo you want to serve. Make it executable. MAKE SURE that the fossil repo you use is world-writable OR that your Web/CGI server is set up to run as the user ID of the owner of the fossil file. ALSO: the DIRECTORY CONTAINING the repo file must be writable by the CGI process. Next, set up an apache vhost entry. Mine looks like: <VirtualHost *:80> ServerAlias fjson ScriptAlias /cgi-bin/ /home/stephan/cvs/fossil/fossil-json/ajax/cgi-bin/ DocumentRoot /home/stephan/cvs/fossil/fossil-json/ajax </VirtualHost> Now add your preferred vhost name (fjson in the above example) to /etc/hosts: 127.0.0.1 ...other aliases... fjson Restart your Apache. Now visit: http://fjson/ that will show the test/demo page. If it doesn't, edit index.html and make sure that: WhAjaj.Connector.options.ajax.url = ...; points to your CGI script. In theory you can also do this over fossil standalone server mode, but i haven't yet tested that particular test page in that mode. |

NO WARRANTY EXPRESSED OR IMPLIED. USE AT YOUR OWN RISK. See http://www.JSON.org/js.html This file creates a global JSON object containing two methods: stringify and parse. JSON.stringify(value, replacer, space) value any JavaScript value, usually an object or array. replacer an optional parameter that determines how object values are stringified for objects. It can be a function or an array of strings. space an optional parameter that specifies the indentation of nested structures. If it is omitted, the text will be packed without extra whitespace. If it is a number, it will specify the number of spaces to indent at each level. If it is a string (such as '\t' or ' '), it contains the characters used to indent at each level. This method produces a JSON text from a JavaScript value. When an object value is found, if the object contains a toJSON method, its toJSON method will be called and the result will be stringified. A toJSON method does not serialize: it returns the value represented by the name/value pair that should be serialized, or undefined if nothing should be serialized. The toJSON method will be passed the key associated with the value, and this will be bound to the object holding the key. For example, this would serialize Dates as ISO strings. Date.prototype.toJSON = function (key) { function f(n) { // Format integers to have at least two digits. return n < 10 ? '0' + n : n; } return this.getUTCFullYear() + '-' + f(this.getUTCMonth() + 1) + '-' + f(this.getUTCDate()) + 'T' + f(this.getUTCHours()) + ':' + f(this.getUTCMinutes()) + ':' + f(this.getUTCSeconds()) + 'Z'; }; You can provide an optional replacer method. It will be passed the key and value of each member, with this bound to the containing object. The value that is returned from your method will be serialized. If your method returns undefined, then the member will be excluded from the serialization. If the replacer parameter is an array of strings, then it will be used to select the members to be serialized. It filters the results such that only members with keys listed in the replacer array are stringified. Values that do not have JSON representations, such as undefined or functions, will not be serialized. Such values in objects will be dropped; in arrays they will be replaced with null. You can use a replacer function to replace those with JSON values. JSON.stringify(undefined) returns undefined. The optional space parameter produces a stringification of the value that is filled with line breaks and indentation to make it easier to read. If the space parameter is a non-empty string, then that string will be used for indentation. If the space parameter is a number, then the indentation will be that many spaces. Example: text = JSON.stringify(['e', {pluribus: 'unum'}]); // text is '["e",{"pluribus":"unum"}]' text = JSON.stringify(['e', {pluribus: 'unum'}], null, '\t'); // text is '[\n\t"e",\n\t{\n\t\t"pluribus": "unum"\n\t}\n]' text = JSON.stringify([new Date()], function (key, value) { return this[key] instanceof Date ? 'Date(' + this[key] + ')' : value; }); // text is '["Date(---current time---)"]' JSON.parse(text, reviver) This method parses a JSON text to produce an object or array. It can throw a SyntaxError exception. The optional reviver parameter is a function that can filter and transform the results. It receives each of the keys and values, and its return value is used instead of the original value. If it returns what it received, then the structure is not modified. If it returns undefined then the member is deleted. Example: // Parse the text.

While clients may use one "requester" object per connection attempt, for connections to the same back-end, using an instance configured for that back-end can simplify usage. This class is designed so that the actual connection-related details (i.e. _how_ it connects to the back-end) may be re-implemented to use a client's preferred connection mechanism (e.g. jQuery). The optional opt parameter may be an object with any (or all) of the properties documented for WhAjaj.Connector.options.ajax.

As a simple example: @code cgi.login = function(name,pw,ajajOpt) { this.sendRequest( {command:"json/login", name:name, password:pw }, ajajOpt ); }; @endcode TODOs: - Caching of page-load requests, with a configurable lifetime. - Use-cases like the above login() function are a tiny bit problematic to implement when each request has a different URL path (i know this from the whiki and fossil implementations).

It is a simple wrapper around WhAjaj.Connector.prototype.sendImpl(), which just normalizes the connection options for sendImpl() and makes sure that opt.beforeSend() is (possibly) called. The request parameter must either be false/null/empty or a fully-populated JSON-able request object (which will be sent as unencoded application/json text), depending on the type of request being made. It is never semantically legal (in this API) for request to be a string/number/true/array value. As a rule, only POST requests use the request data. GET requests should encode their data in opt.url or opt.urlParam (see below). opt must contain the network-related parameters for the request. Paramters _not_ set in opt are pulled from this.options or WhAjaj.Connector.options.ajax (in that order, using the first value it finds). Thus the set of connection-level options used for the request are a superset of those various sources. The "normalized" (or "superimposed") opt object's URL may be modified before the request is sent, as follows: if opt.urlParam is a string then it is assumed to be properly URL-encoded parameters and is appended to the opt.url. If it is an Object then it is assumed to be a one-dimensional set of key/value pairs with simple values (numbers, strings, booleans, null, and NOT objects/arrays). The keys/values are URL-encoded and appended to the URL. The beforeSend() callback (see below) can modify the options object before the request attempt is made. The callbacks in the normalized opt object will be triggered as follows (if they are set to Function values): - beforeSend(request,opt) will be called before any network processing starts. If beforeSend() throws then no other callbacks are triggered and this function propagates the exception. This function is passed normalized connection options as its second parameter, and changes this function makes to that object _will_ be used for the pending connection attempt. - onError(request,opt) will be called if a connection to the back-end cannot be established. It will be passed the original request object (which might be null, depending on the request type) and the normalized options object. In the error case, the opt object passed to onError() "should" have a property called "errorMessage" which contains a description of the problem. - onError(request,opt) will also be called if connection succeeds but the response is not JSON data. - onResponse(response,request) will be called if the response returns JSON data. That data might hold an error response code - clients need to check for that. It is passed the response object (a plain object) and the original request object. - afterSend(request,opt) will be called directly after the AJAX request is finished, before onError() or onResonse() are called. Possible TODO: we explicitly do NOT pass the response to this function in order to keep the line between the responsibilities of the various callback clear (otherwise this could be used the same as onResponse()). In practice it would sometimes be useful have the response passed to this function, mainly for logging/debugging purposes. The return value from this function is meaningless because AJAX operations tend to take place asynchronously. */ WhAjaj.Connector.prototype.sendRequest = function(request,opt) { if( !WhAjaj.isFunction(this.sendImpl) ) { throw new Error("This object has no sendImpl() member function!

The lastest zlib FAQ is at http://zlib.net/zlib_faq.html 1. Is zlib Y2K-compliant? Yes. zlib doesn't handle dates. 2. Where can I get a Windows DLL version? The zlib sources can be compiled without change to produce a DLL. See the file win32/DLL_FAQ.txt in the zlib distribution. Pointers to the precompiled DLL are found in the zlib web site at http://zlib.net/ . 3. Where can I get a Visual Basic interface to zlib? See * http://marknelson.us/1997/01/01/zlib-engine/ * win32/DLL_FAQ.txt in the zlib distribution 4. compress() returns Z_BUF_ERROR. Make sure that before the call of compress(), the length of the compressed buffer is equal to the available size of the compressed buffer and not zero. For Visual Basic, check that this parameter is passed by reference ("as any"), not by value ("as long"). 5. deflate() or inflate() returns Z_BUF_ERROR. Before making the call, make sure that avail_in and avail_out are not zero. When setting the parameter flush equal to Z_FINISH, also make sure that avail_out is big enough to allow processing all pending input. Note that a Z_BUF_ERROR is not fatal--another call to deflate() or inflate() can be made with more input or output space. A Z_BUF_ERROR may in fact be unavoidable depending on how the functions are used, since it is not possible to tell whether or not there is more output pending when strm.avail_out returns with zero. See http://zlib.net/zlib_how.html for a heavily annotated example. 6. Where's the zlib documentation (man pages, etc.)? It's in zlib.h . Examples of zlib usage are in the files test/example.c and test/minigzip.c, with more in examples/ . 7. Why don't you use GNU autoconf or libtool or ...? Because we would like to keep zlib as a very small and simple package. zlib is rather portable and doesn't need much configuration. 8. I found a bug in zlib. Most of the time, such problems are due to an incorrect usage of zlib. Please try to reproduce the problem with a small program and send the corresponding source to us at zlib@gzip.org . Do not send multi-megabyte data files without prior agreement. 9. Why do I get "undefined reference to gzputc"? If "make test" produces something like example.o(.text+0x154): undefined reference to `gzputc' check that you don't have old files libz.* in /usr/lib, /usr/local/lib or /usr/X11R6/lib. Remove any old versions, then do "make install". 10. I need a Delphi interface to zlib. See the contrib/delphi directory in the zlib distribution. 11. Can zlib handle .zip archives? Not by itself, no. See the directory contrib/minizip in the zlib distribution. 12. Can zlib handle .Z files? No, sorry. You have to spawn an uncompress or gunzip subprocess, or adapt the code of uncompress on your own. 13. How can I make a Unix shared library? By default a shared (and a static) library is built for Unix. So: make distclean ./configure make 14. How do I install a shared zlib library on Unix? After the above, then: make install However, many flavors of Unix come with a shared zlib already installed. Before going to the trouble of compiling a shared version of zlib and trying to install it, you may want to check if it's already there! If you can #include <zlib.h>, it's there. The -lz option will probably link to it. You can check the version at the top of zlib.h or with the ZLIB_VERSION symbol defined in zlib.h . 15. I have a question about OttoPDF. We are not the authors of OttoPDF. The real author is on the OttoPDF web site: Joel Hainley, jhainley@myndkryme.com. 16. Can zlib decode Flate data in an Adobe PDF file? Yes. See http://www.pdflib.com/ . To modify PDF forms, see http://sourceforge.net/projects/acroformtool/ . 17. Why am I getting this "register_frame_info not found" error on Solaris? After installing zlib 1.1.4 on Solaris 2.6, running applications using zlib generates an error such as: ld.so.1: rpm: fatal: relocation error: file /usr/local/lib/libz.so: symbol __register_frame_info: referenced symbol not found The symbol __register_frame_info is not part of zlib, it is generated by the C compiler (cc or gcc). You must recompile applications using zlib which have this problem. This problem is specific to Solaris. See http://www.sunfreeware.com for Solaris versions of zlib and applications using zlib. 18. Why does gzip give an error on a file I make with compress/deflate? The compress and deflate functions produce data in the zlib format, which is different and incompatible with the gzip format. The gz* functions in zlib on the other hand use the gzip format. Both the zlib and gzip formats use the same compressed data format internally, but have different headers and trailers around the compressed data. 19. Ok, so why are there two different formats? The gzip format was designed to retain the directory information about a single file, such as the name and last modification date. The zlib format on the other hand was designed for in-memory and communication channel applications, and has a much more compact header and trailer and uses a faster integrity check than gzip. 20. Well that's nice, but how do I make a gzip file in memory? You can request that deflate write the gzip format instead of the zlib format using deflateInit2(). You can also request that inflate decode the gzip format using inflateInit2(). Read zlib.h for more details. 21. Is zlib thread-safe? Yes. However any library routines that zlib uses and any application- provided memory allocation routines must also be thread-safe. zlib's gz* functions use stdio library routines, and most of zlib's functions use the library memory allocation routines by default. zlib's *Init* functions allow for the application to provide custom memory allocation routines. Of course, you should only operate on any given zlib or gzip stream from a single thread at a time. 22. Can I use zlib in my commercial application? Yes. Please read the license in zlib.h. 23. Is zlib under the GNU license? No. Please read the license in zlib.h. 24. The license says that altered source versions must be "plainly marked". So what exactly do I need to do to meet that requirement? You need to change the ZLIB_VERSION and ZLIB_VERNUM #defines in zlib.h. In particular, the final version number needs to be changed to "f", and an identification string should be appended to ZLIB_VERSION. Version numbers x.x.x.f are reserved for modifications to zlib by others than the zlib maintainers. For example, if the version of the base zlib you are altering is "1.2.3.4", then in zlib.h you should change ZLIB_VERNUM to 0x123f, and ZLIB_VERSION to something like "1.2.3.f-zachary-mods-v3". You can also update the version strings in deflate.c and inftrees.c. For altered source distributions, you should also note the origin and nature of the changes in zlib.h, as well as in ChangeLog and README, along with the dates of the alterations. The origin should include at least your name (or your company's name), and an email address to contact for help or issues with the library. Note that distributing a compiled zlib library along with zlib.h and zconf.h is also a source distribution, and so you should change ZLIB_VERSION and ZLIB_VERNUM and note the origin and nature of the changes in zlib.h as you would for a full source distribution. 25. Will zlib work on a big-endian or little-endian architecture, and can I exchange compressed data between them? Yes and yes. 26. Will zlib work on a 64-bit machine? Yes. It has been tested on 64-bit machines, and has no dependence on any data types being limited to 32-bits in length. If you have any difficulties, please provide a complete problem report to zlib@gzip.org 27. Will zlib decompress data from the PKWare Data Compression Library? No. The PKWare DCL uses a completely different compressed data format than does PKZIP and zlib. However, you can look in zlib's contrib/blast directory for a possible solution to your problem. 28. Can I access data randomly in a compressed stream? No, not without some preparation. If when compressing you periodically use Z_FULL_FLUSH, carefully write all the pending data at those points, and keep an index of those locations, then you can start decompression at those points. You have to be careful to not use Z_FULL_FLUSH too often, since it can significantly degrade compression. Alternatively, you can scan a deflate stream once to generate an index, and then use that index for random access. See examples/zran.c . 29. Does zlib work on MVS, OS/390, CICS, etc.? It has in the past, but we have not heard of any recent evidence. There were working ports of zlib 1.1.4 to MVS, but those links no longer work. If you know of recent, successful applications of zlib on these operating systems, please let us know. Thanks. 30. Is there some simpler, easier to read version of inflate I can look at to understand the deflate format? First off, you should read RFC 1951. Second, yes. Look in zlib's contrib/puff directory. 31. Does zlib infringe on any patents? As far as we know, no. In fact, that was originally the whole point behind zlib. Look here for some more information: http://www.gzip.org/#faq11 32. Can zlib work with greater than 4 GB of data? Yes. inflate() and deflate() will process any amount of data correctly. Each call of inflate() or deflate() is limited to input and output chunks of the maximum value that can be stored in the compiler's "unsigned int" type, but there is no limit to the number of chunks. Note however that the strm.total_in and strm_total_out counters may be limited to 4 GB. These counters are provided as a convenience and are not used internally by inflate() or deflate(). The application can easily set up its own counters updated after each call of inflate() or deflate() to count beyond 4 GB. compress() and uncompress() may be limited to 4 GB, since they operate in a single call. gzseek() and gztell() may be limited to 4 GB depending on how zlib is compiled. See the zlibCompileFlags() function in zlib.h. The word "may" appears several times above since there is a 4 GB limit only if the compiler's "long" type is 32 bits. If the compiler's "long" type is 64 bits, then the limit is 16 exabytes. 33. Does zlib have any security vulnerabilities? The only one that we are aware of is potentially in gzprintf(). If zlib is compiled to use sprintf() or vsprintf(), then there is no protection against a buffer overflow of an 8K string space (or other value as set by gzbuffer()), other than the caller of gzprintf() assuring that the output will not exceed 8K. On the other hand, if zlib is compiled to use snprintf() or vsnprintf(), which should normally be the case, then there is no vulnerability. The ./configure script will display warnings if an insecure variation of sprintf() will be used by gzprintf(). Also the zlibCompileFlags() function will return information on what variant of sprintf() is used by gzprintf(). If you don't have snprintf() or vsnprintf() and would like one, you can find a portable implementation here: http://www.ijs.si/software/snprintf/ Note that you should be using the most recent version of zlib. Versions 1.1.3 and before were subject to a double-free vulnerability, and versions 1.2.1 and 1.2.2 were subject to an access exception when decompressing invalid compressed data. 34. Is there a Java version of zlib? Probably what you want is to use zlib in Java. zlib is already included as part of the Java SDK in the java.util.zip package. If you really want a version of zlib written in the Java language, look on the zlib home page for links: http://zlib.net/ . 35. I get this or that compiler or source-code scanner warning when I crank it up to maximally-pedantic. Can't you guys write proper code? Many years ago, we gave up attempting to avoid warnings on every compiler in the universe. It just got to be a waste of time, and some compilers were downright silly as well as contradicted each other. So now, we simply make sure that the code always works. 36. Valgrind (or some similar memory access checker) says that deflate is performing a conditional jump that depends on an uninitialized value. Isn't that a bug? No. That is intentional for performance reasons, and the output of deflate is not affected. This only started showing up recently since zlib 1.2.x uses malloc() by default for allocations, whereas earlier versions used calloc(), which zeros out the allocated memory. Even though the code was correct, versions 1.2.4 and later was changed to not stimulate these checkers. 37. Will zlib read the (insert any ancient or arcane format here) compressed data format? Probably not. Look in the comp.compression FAQ for pointers to various formats and associated software. 38. How can I encrypt/decrypt zip files with zlib? zlib doesn't support encryption. The original PKZIP encryption is very weak and can be broken with freely available programs. To get strong encryption, use GnuPG, http://www.gnupg.org/ , which already includes zlib compression. For PKZIP compatible "encryption", look at http://www.info-zip.org/ 39. What's the difference between the "gzip" and "deflate" HTTP 1.1 encodings? "gzip" is the gzip format, and "deflate" is the zlib format. They should probably have called the second one "zlib" instead to avoid confusion with the raw deflate compressed data format. While the HTTP 1.1 RFC 2616 correctly points to the zlib specification in RFC 1950 for the "deflate" transfer encoding, there have been reports of servers and browsers that incorrectly produce or expect raw deflate data per the deflate specification in RFC 1951, most notably Microsoft. So even though the "deflate" transfer encoding using the zlib format would be the more efficient approach (and in fact exactly what the zlib format was designed for), using the "gzip" transfer encoding is probably more reliable due to an unfortunate choice of name on the part of the HTTP 1.1 authors. Bottom line: use the gzip format for HTTP 1.1 encoding. 40. Does zlib support the new "Deflate64" format introduced by PKWare? No. PKWare has apparently decided to keep that format proprietary, since they have not documented it as they have previous compression formats. In any case, the compression improvements are so modest compared to other more modern approaches, that it's not worth the effort to implement. 41. I'm having a problem with the zip functions in zlib, can you help? There are no zip functions in zlib. You are probably using minizip by Giles Vollant, which is found in the contrib directory of zlib. It is not part of zlib. In fact none of the stuff in contrib is part of zlib. The files in there are not supported by the zlib authors. You need to contact the authors of the respective contribution for help. 42. The match.asm code in contrib is under the GNU General Public License. Since it's part of zlib, doesn't that mean that all of zlib falls under the GNU GPL? No. The files in contrib are not part of zlib. They were contributed by other authors and are provided as a convenience to the user within the zlib distribution. Each item in contrib has its own license. 43. Is zlib subject to export controls? What is its ECCN? zlib is not subject to export controls, and so is classified as EAR99. 44. Can you please sign these lengthy legal documents and fax them back to us so that we can use your software in our product? No. Go away. Shoo. |

All the code is thread safe. The data format used by the zlib library is described by RFCs (Request for Comments) 1950 to 1952 in the files http://tools.ietf.org/html/rfc1950 (zlib format), rfc1951 (deflate format) and rfc1952 (gzip format). All functions of the compression library are documented in the file zlib.h (volunteer to write man pages welcome, contact zlib@gzip.org). A usage example of the library is given in the file test/example.c which also tests that the library is working correctly. Another example is given in the file test/minigzip.c. The compression library itself is composed of all source files in the root directory. To compile all files and run the test program, follow the instructions given at the top of Makefile.in. In short "./configure; make test", and if that goes well, "make install" should work for most flavors of Unix. For Windows, use one of the special makefiles in win32/ or contrib/vstudio/ . For VMS, use make_vms.com. Questions about zlib should be sent to <zlib@gzip.org>, or to Gilles Vollant <info@winimage.com> for the Windows DLL version. The zlib home page is http://zlib.net/ . Before reporting a problem, please check this site to verify that you have the latest version of zlib; otherwise get the latest version and check whether the problem still exists or not. PLEASE read the zlib FAQ http://zlib.net/zlib_faq.html before asking for help. Mark Nelson <markn@ieee.org> wrote an article about zlib for the Jan. 1997 issue of Dr. Dobb's Journal; a copy of the article is available at http://marknelson.us/1997/01/01/zlib-engine/ . The changes made in version 1.2.11 are documented in the file ChangeLog. Unsupported third party contributions are provided in directory contrib/ . zlib is available in Java using the java.util.zip package, documented at http://java.sun.com/developer/technicalArticles/Programming/compression/ . A Perl interface to zlib written by Paul Marquess <pmqs@cpan.org> is available at CPAN (Comprehensive Perl Archive Network) sites, including http://search.cpan.org/~pmqs/IO-Compress-Zlib/ . A Python interface to zlib written by A.M. Kuchling <amk@amk.ca> is available in Python 1.5 and later versions, see http://docs.python.org/library/zlib.html . zlib is built into tcl: http://wiki.tcl.tk/4610 . An experimental package to read and write files in .zip format, written on top of zlib by Gilles Vollant <info@winimage.com>, is available in the contrib/minizip directory of zlib. Notes for some targets: - For Windows DLL versions, please see win32/DLL_FAQ.txt - For 64-bit Irix, deflate.c must be compiled without any optimization. With -O, one libpng test fails. The test works in 32 bit mode (with the -n32 compiler flag). The compiler bug has been reported to SGI. - zlib doesn't work with gcc 2.6.3 on a DEC 3000/300LX under OSF/1 2.1 it works when compiled with cc. - On Digital Unix 4.0D (formely OSF/1) on AlphaServer, the cc option -std1 is necessary to get gzprintf working correctly. This is done by configure. - zlib doesn't work on HP-UX 9.05 with some versions of /bin/cc. It works with other compilers. Use "make test" to check your compiler. - gzdopen is not supported on RISCOS or BEOS. - For PalmOs, see http://palmzlib.sourceforge.net/ Acknowledgments: The deflate format used by zlib was defined by Phil Katz. The deflate and zlib specifications were written by L. Peter Deutsch. Thanks to all the people who reported problems and suggested various improvements in zlib; they are too numerous to cite here.

It provides Ada-style access to the ZLib C library. Here are the main changes since ZLib.Ada 1.2: - Attension: ZLib.Read generic routine have a initialization requirement for Read_Last parameter now. It is a bit incompartible with previous version, but extends functionality, we could use new parameters Allow_Read_Some and Flush now. - Added Is_Open routines to ZLib and ZLib.Streams packages. - Add pragma Assert to check Stream_Element is 8 bit. - Fix extraction to buffer with exact known decompressed size. Error reported by Steve Sangwine. - Fix definition of ULong (changed to unsigned_long), fix regression on 64 bits computers. Patch provided by Pascal Obry. - Add Status_Error exception definition. - Add pragma Assertion that Ada.Streams.Stream_Element size is 8 bit. How to build ZLib.Ada under GNAT You should have the ZLib library already build on your computer, before building ZLib.Ada. Make the directory of ZLib.Ada sources current and issue the command: gnatmake test -largs -L<directory where libz.a is> -lz Or use the GNAT project file build for GNAT 3.15 or later: gnatmake -Pzlib.gpr -L<directory where libz.a is> How to build ZLib.Ada under Aonix ObjectAda for Win32 7.2.2 1. Make a project with all *.ads and *.adb files from the distribution. 2. Build the libz.a library from the ZLib C sources. 3. Rename libz.a to z.lib. 4. Add the library z.lib to the project. 5. Add the libc.lib library from the ObjectAda distribution to the project. 6. Build the executable using test.adb as a main procedure. How to use ZLib.Ada The source files test.adb and read.adb are small demo programs that show the main functionality of ZLib.Ada. The routines from the package specifications are commented.

The files changed/added by this patch are: README.686 match.S The speedup that this patch provides varies, depending on whether the compiler used to build the original version of zlib falls afoul of the PPro's speed traps. My own tests show a speedup of around 10-20% at the default compression level, and 20-30% using -9, against a version compiled using gcc 2.7.2.3. Your mileage may vary. Note that this code has been tailored for the PPro/PII in particular, and will not perform particuarly well on a Pentium. If you are using an assembler other than GNU as, you will have to translate match.S to use your assembler's syntax. (Have fun.) Brian Raiter breadbox@muppetlabs.com April, 1998 Added for zlib 1.1.3: The patches come from http://www.muppetlabs.com/~breadbox/software/assembly.html To compile zlib with this asm file, copy match.S to the zlib directory then do: CFLAGS="-O3 -DASMV" ./configure make OBJA=match.o Update: I've been ignoring these assembly routines for years, believing that gcc's generated code had caught up with it sometime around gcc 2.95 and the major rearchitecting of the Pentium 4. However, I recently learned that, despite what I believed, this code still has some life in it. On the Pentium 4 and AMD64 chips, it continues to run about 8% faster than the code produced by gcc 4.1.

The original ZLib unit is Copyright (c) 1997,99 Borland Corp., and is based on zlib version 1.0.4. There are a series of bugs and security problems associated with that old zlib version, and we recommend the users to update their ZLib unit. Summary of modifications ======================== - Improved makefile, adapted to zlib version 1.2.1. - Some field types from TZStreamRec are changed from Integer to Longint, for consistency with the zlib.h header, and for 64-bit readiness. - The zlib_version constant is updated. - The new Z_RLE strategy has its corresponding symbolic constant. - The allocation and deallocation functions and function types (TAlloc, TFree, zlibAllocMem and zlibFreeMem) are now cdecl, and _malloc and _free are added as C RTL stubs. As a result, the original C sources of zlib can be compiled out of the box, and linked to the ZLib unit. Suggestions for improvements ============================ Currently, the ZLib unit provides only a limited wrapper around the zlib library, and much of the original zlib functionality is missing. Handling compressed file formats like ZIP/GZIP or PNG cannot be implemented without having this functionality. Applications that handle these formats are either using their own, duplicated code, or not using the ZLib unit at all. Here are a few suggestions: - Checksum class wrappers around adler32() and crc32(), similar to the Java classes that implement the java.util.zip.Checksum interface. - The ability to read and write raw deflate streams, without the zlib stream header and trailer. Raw deflate streams are used in the ZIP file format. - The ability to read and write gzip streams, used in the GZIP file format, and normally produced by the gzip program. - The ability to select a different compression strategy, useful to PNG and MNG image compression, and to multimedia compression in general. Besides the compression level TCompressionLevel = (clNone, clFastest, clDefault, clMax); which, in fact, could have used the 'z' prefix and avoided TColor-like symbols TCompressionLevel = (zcNone, zcFastest, zcDefault, zcMax); there could be a compression strategy TCompressionStrategy = (zsDefault, zsFiltered, zsHuffmanOnly, zsRle); - ZIP and GZIP stream handling via TStreams. -- Cosmin Truta <cosmint@cs.ubbcluj.ro> |

See DotZLib/UnitTests.cs for examples. Directory structure: -------------------- LICENSE_1_0.txt - License file. readme.txt - This file. DotZLib.chm - Class library documentation DotZLib.build - NAnt build file DotZLib.sln - Microsoft Visual Studio 2003 solution file DotZLib\*.cs - Source files for the class library Unit tests: ----------- The file DotZLib/UnitTests.cs contains unit tests for use with NUnit 2.1 or higher. To include unit tests in the build, define nunit before building. Build instructions: ------------------- 1. Using Visual Studio.Net 2003: Open DotZLib.sln in VS.Net and build from there. Output file (DotZLib.dll) will be found ./DotZLib/bin/release or ./DotZLib/bin/debug, depending on you are building the release or debug version of the library. Check DotZLib/UnitTests.cs for instructions on how to include unit tests in the build. 2. Using NAnt: Open a command prompt with access to the build environment and run nant in the same directory as the DotZLib.build file. You can define 2 properties on the nant command-line to control the build: debug={true|false} to toggle between release/debug builds (default=true). nunit={true|false} to include or esclude unit tests (default=true). Also the target clean will remove binaries. Output file (DotZLib.dll) will be found in either ./DotZLib/bin/release or ./DotZLib/bin/debug, depending on whether you are building the release or debug version of the library. Examples: nant -D:debug=false -D:nunit=false will build a release mode version of the library without unit tests. nant will build a debug version of the library with unit tests nant clean will remove all previously built files. --------------------------------- Copyright (c) Henrik Ravn 2004 Use, modification and distribution are subject to the Boost Software License, Version 1.0.

The code lengths are lens[0..codes-1]. Each length corresponds to the symbols 0..codes-1. The Huffman code is generated by first sorting the symbols by length from short to long, and retaining the symbol order for codes with equal lengths. Then the code starts with all zero bits for the first code of the shortest length, and the codes are integer increments for the same length, and zeros are appended as the length increases. For the deflate format, these bits are stored backwards from their more natural integer increment ordering, and so when the decoding tables are built in the large loop below, the integer codes are incremented backwards. This routine assumes, but does not check, that all of the entries in lens[] are in the range 0..MAXBITS. The caller must assure this. 1..MAXBITS is interpreted as that code length. zero means that that symbol does not occur in this code. The codes are sorted by computing a count of codes for each length, creating from that a table of starting indices for each length in the sorted table, and then entering the symbols in order in the sorted table. The sorted table is work[], with that space being provided by the caller. The length counts are used for other purposes as well, i.e. finding the minimum and maximum length codes, determining if there are any codes at all, checking for a valid set of lengths, and looking ahead at length counts to determine sub-table sizes when building the decoding tables. */ /* accumulate lengths for codes (assumes lens[] all in 0..MAXBITS) */ for (len = 0; len <= MAXBITS; len++) count[len] = 0; for (sym = 0; sym < codes; sym++) count[lens[sym]]++; /* bound code lengths, force root to be within code lengths */ root = *bits; for (max = MAXBITS; max >= 1; max--) if (count[max] != 0) break; if (root > max) root = max; if (max == 0) return -1; /* no codes! */ for (min = 1; min <= MAXBITS; min++) if (count[min] != 0) break; if (root < min) root = min; /* check for an over-subscribed or incomplete set of lengths */ left = 1; for (len = 1; len <= MAXBITS; len++) { left <<= 1; left -= count[len]; if (left < 0) return -1; /* over-subscribed */ } if (left > 0 && (type == CODES || max != 1)) return -1; /* incomplete set */ /* generate offsets into symbol table for each length for sorting */ offs[1] = 0; for (len = 1; len < MAXBITS; len++) offs[len + 1] = offs[len] + count[len]; /* sort symbols by length, by symbol order within each length */ for (sym = 0; sym < codes; sym++) if (lens[sym] != 0) work[offs[lens[sym]]++] = (unsigned short)sym; /* Create and fill in decoding tables. In this loop, the table being filled is at next and has curr index bits. The code being used is huff with length len. That code is converted to an index by dropping drop bits off of the bottom. For codes where len is less than drop + curr, those top drop + curr - len bits are incremented through all values to fill the table with replicated entries. root is the number of index bits for the root table. When len exceeds root, sub-tables are created pointed to by the root entry with an index of the low root bits of huff. This is saved in low to check for when a new sub-table should be started. drop is zero when the root table is being filled, and drop is root when sub-tables are being filled. When a new sub-table is needed, it is necessary to look ahead in the code lengths to determine what size sub-table is needed. The length counts are used for this, and so count[] is decremented as codes are entered in the tables. used keeps track of how many table entries have been allocated from the provided *table space.

inffas86.c is a hand tuned assembler version of * * inffast.c -- fast decoding * Copyright (C) 1995-2003 Mark Adler * For conditions of distribution and use, see copyright notice in zlib.h * * Copyright (C) 2003 Chris Anderson <christop@charm.net> * Please use the copyright conditions above. * * Dec-29-2003 -- I added AMD64 inflate asm support. This version is also * slightly quicker on x86 systems because, instead of using rep movsb to copy * data, it uses rep movsw, which moves data in 2-byte chunks instead of single * bytes. I've tested the AMD64 code on a Fedora Core 1 + the x86_64 updates * from http://fedora.linux.duke.edu/fc1_x86_64 * which is running on an Athlon 64 3000+ / Gigabyte GA-K8VT800M system with * 1GB ram. The 64-bit version is about 4% faster than the 32-bit version, * when decompressing mozilla-source-1.3.tar.gz. * * Mar-13-2003 -- Most of this is derived from inffast.S which is derived from * the gcc -S output of zlib-1.2.0/inffast.c. Zlib-1.2.0 is in beta release at * the moment. I have successfully compiled and tested this code with gcc2.96, * gcc3.2, icc5.0, msvc6.0. It is very close to the speed of inffast.S * compiled with gcc -DNO_MMX, but inffast.S is still faster on the P3 with MMX * enabled. I will attempt to merge the MMX code into this version. Newer * versions of this and inffast.S can be found at * http://www.eetbeetee.com/zlib/ and http://www.charm.net/~christop/zlib/ */ #include "zutil.h" #include "inftrees.h" #include "inflate.h" #include "inffast.h" /* Mark Adler's comments from inffast.c: */ /* Decode literal, length, and distance codes and write out the resulting literal and match bytes until either not enough input or output is available, an end-of-block is encountered, or a data error is encountered. When large enough input and output buffers are supplied to inflate(), for example, a 16K input buffer and a 64K output buffer, more than 95% of the inflate execution time is spent in this routine. Entry assumptions: state->mode == LEN strm->avail_in >= 6 strm->avail_out >= 258 start >= strm->avail_out state->bits < 8 On return, state->mode is one of: LEN -- ran out of enough output space or enough available input TYPE -- reached end of block code, inflate() to interpret next block BAD -- error in block data Notes: - The maximum input bits used by a length/distance pair is 15 bits for the length code, 5 bits for the length extra, 15 bits for the distance code, and 13 bits for the distance extra. This totals 48 bits, or six bytes. Therefore if strm->avail_in >= 6, then there is enough input to avoid checking for available input while decoding. - The maximum bytes that a single length/distance pair can output is 258 bytes, which is the maximum length that can be coded. inflate_fast() requires strm->avail_out >= 258 for each loop to avoid checking for output space. */ void inflate_fast(strm, start) z_streamp strm; unsigned

conditions of distribution and use, see copyright notice in zlib.h * * Copyright (C) 2003 Chris Anderson <christop@charm.net> * Please use the copyright conditions above. * * This version (Jan-23-2003) of inflate_fast was coded and tested under * GNU/Linux on a pentium 3, using the gcc-3.2 compiler distribution. On that * machine, I found that gzip style archives decompressed about 20% faster than * the gcc-3.2 -O3 -fomit-frame-pointer compiled version. Your results will * depend on how large of a buffer is used for z_stream.next_in & next_out * (8K-32K worked best for my 256K cpu cache) and how much overhead there is in * stream processing I/O and crc32/addler32. In my case, this routine used * 70% of the cpu time and crc32 used 20%. * * I am confident that this version will work in the general case, but I have * not tested a wide variety of datasets or a wide variety of platforms. * * Jan-24-2003 -- Added -DUSE_MMX define for slightly faster inflating. * It should be a runtime flag instead of compile time flag... * * Jan-26-2003 -- Added runtime check for MMX support with cpuid instruction. * With -DUSE_MMX, only MMX code is compiled. With -DNO_MMX, only non-MMX code * is compiled. Without either option, runtime detection is enabled. Runtime * detection should work on all modern cpus and the recomended algorithm (flip * ID bit on eflags and then use the cpuid instruction) is used in many * multimedia applications. Tested under win2k with gcc-2.95 and gas-2.12 * distributed with cygwin3. Compiling with gcc-2.95 -c inffast.S -o * inffast.obj generates a COFF object which can then be linked with MSVC++ * compiled code. Tested under FreeBSD 4.7 with gcc-2.95. * * Jan-28-2003 -- Tested Athlon XP... MMX mode is slower than no MMX (and * slower than compiler generated code). Adjusted cpuid check to use the MMX * code only for Pentiums < P4 until I have more data on the P4. Speed * improvment is only about 15% on the Athlon when compared with code generated * with MSVC++. Not sure yet, but I think the P4 will also be slower using the * MMX mode because many of it's x86 ALU instructions execute in .5 cycles and * have less latency than MMX ops. Added code to buffer the last 11 bytes of * the input stream since the MMX code grabs bits in chunks of 32, which * differs from the inffast.c algorithm. I don't think there would have been * read overruns where a page boundary was crossed (a segfault), but there * could have been overruns when next_in ends on unaligned memory (unintialized * memory read). * * Mar-13-2003 -- P4 MMX is slightly slower than P4 NO_MMX. I created a C * version of the non-MMX code so that it doesn't depend on zstrm and zstate * structure offsets which are hard coded in this file. This was last tested * with zlib-1.2.0 which is currently in beta testing, newer versions of this * and inffas86.c can be found at http://www.eetbeetee.com/zlib/ and * http://www.charm.net/~christop/zlib/ */ /* * if you have underscore linking problems (_inflate_fast undefined), try * using -DGAS_COFF */ #if ! defined( GAS_COFF ) && ! defined( GAS_ELF ) #if defined( WIN32 ) || defined( __CYGWIN__ ) #define GAS_COFF /* windows object format */ #else #define GAS_ELF #endif #endif /* !

It allows you to do things like: gzofstream outf("blah.gz"); outf << "These go into the gzip file " << 123 << endl; It does this by deriving a specialized stream buffer for gzipped files, which is the way Stroustrup would have done it. :-> The gzifstream and gzofstream classes were originally written by Kevin Ruland and made available in the zlib contrib/iostream directory. The older version still compiles under gcc 2.xx, but not under gcc 3.xx, which sparked the development of this version. The new classes are as standard-compliant as possible, closely following the approach of the standard library's fstream classes. It compiles under gcc versions 3.2 and 3.3, but not under gcc 2.xx. This is mainly due to changes in the standard library naming scheme. The new version of gzifstream/gzofstream/gzfilebuf differs from the previous one in the following respects: - added showmanyc - added setbuf, with support for unbuffered output via setbuf(0,0) - a few bug fixes of stream behavior - gzipped output file opened with default compression level instead of maximum level - setcompressionlevel()/strategy() members replaced by single setcompression() The code is provided "as is", with the permission to use, copy, modify, distribute and sell it for any purpose without fee.

When large enough input and output buffers are supplied to inflate(), for example, a 16K input buffer and a 64K output buffer, more than 95% of the inflate execution time is spent in this routine. Entry assumptions: state->mode == LEN strm->avail_in >= 6 strm->avail_out >= 258 start >= strm->avail_out state->bits < 8 On return, state->mode is one of: LEN -- ran out of enough output space or enough available input TYPE -- reached end of block code, inflate() to interpret next block BAD -- error in block data Notes: - The maximum input bits used by a length/distance pair is 15 bits for the length code, 5 bits for the length extra, 15 bits for the distance code, and 13 bits for the distance extra. This totals 48 bits, or six bytes. Therefore if strm->avail_in >= 6, then there is enough input to avoid checking for available input while decoding. - The maximum bytes that a single length/distance pair can output is 258 bytes, which is the maximum length that can be coded. inflate_fast() requires strm->avail_out >= 258 for each loop to avoid checking for output space. */ typedef struct inffast_ar { /* 64 32 x86 x86_64 */ /* ar offset register */ /* 0 0 */ void *esp; /* esp save */ /* 8 4 */ void *ebp; /* ebp save */ /* 16 8 */ unsigned char FAR *in; /* esi rsi local strm->next_in */ /* 24 12 */ unsigned char FAR *last; /* r9 while in < last */ /* 32 16 */ unsigned char FAR *out; /* edi rdi local strm->next_out */ /* 40 20 */ unsigned char FAR *beg; /* inflate()'s init next_out */ /* 48 24 */ unsigned char FAR *end; /* r10 while out < end */ /* 56 28 */ unsigned char FAR *window;/* size of window, wsize!=0 */ /* 64 32 */ code const FAR *lcode; /* ebp rbp local strm->lencode */ /* 72 36 */ code const FAR *dcode; /* r11 local strm->distcode */ /* 80 40 */ size_t /*unsigned long */hold; /* edx rdx local strm->hold */ /* 88 44 */ unsigned bits; /* ebx rbx local strm->bits */ /* 92 48 */ unsigned wsize; /* window size */ /* 96 52 */ unsigned write; /* window write index */ /*100 56 */ unsigned lmask; /* r12 mask for lcode */ /*104 60 */ unsigned dmask; /* r13 mask for dcode */ /*108 64 */ unsigned len; /* r14 match length */ /*112 68 */ unsigned dist; /* r15 match distance */ /*116 72 */ unsigned status; /* set when state chng*/ } type_ar; #ifdef ASMINF void inflate_fast(strm, start) z_streamp strm; unsigned start; /* inflate()'s starting value for strm->avail_out */ { struct inflate_state FAR *state; type_ar ar; void inffas8664fnc(struct inffast_ar * par); #if (defined( __GNUC__ ) && defined( __amd64__ ) && ! defined( __i386 )) || (defined(_MSC_VER) && defined(_M_AMD64)) #define PAD_AVAIL_IN 6 #define PAD_AVAIL_OUT 258 #else #define PAD_AVAIL_IN 5 #define PAD_AVAIL_OUT 257 #endif /* copy state to local variables */ state = (struct inflate_state FAR *)strm->state; ar.in = strm->next_in; ar.last = ar.in + (strm->avail_in - PAD_AVAIL_IN); ar.out = strm->next_out; ar.beg = ar.out - (start - strm->avail_out); ar.end = ar.out + (strm->avail_out - PAD_AVAIL_OUT); ar.wsize = state->wsize; ar.write = state->wnext; ar.window = state->window; ar.hold = state->hold; ar.bits = state->bits; ar.lcode = state->lencode; ar.dcode = state->distcode; ar.lmask = (1U << state->lenbits) - 1; ar.dmask = (1U << state->distbits) - 1; /* decode literals and length/distances until end-of-block or not enough input data or output space */ /* align in on 1/2 hold size boundary */ while (((size_t)(void *)ar.in & (sizeof(ar.hold) / 2 - 1)) != 0) { ar.hold += (unsigned long)*ar.in++ << ar.bits; ar.bits += 8; } inffas8664fnc(&ar); if (ar.status > 1) { if (ar.status == 2) strm->msg = "invalid literal/length code"; else if (ar.status == 3) strm->msg = "invalid distance code"; else strm->msg = "invalid distance too far back"; state->mode = BAD; } else if ( ar.status == 1 ) { state->mode = TYPE; } /* return unused bytes (on entry, bits < 8, so in won't go too far back) */ ar.len = ar.bits >> 3; ar.in -= ar.len; ar.bits -= ar.len << 3; ar.hold &= (1U << ar.bits) - 1; /* update state and return */ strm->next_in = ar.in; strm->next_out = ar.out; strm->avail_in = (unsigned)(ar.in < ar.last ?

You can also get object files here: http://www.winimage.com/zLibDll/zlib124_masm_obj.zip define ASMV and ASMINF in your project. Include inffas8664.c in your source tree, and inffasx64.obj and gvmat64.obj as object to link. Build instructions ------------------ run bld_64.bat with Microsoft Macro Assembler (x64) for AMD64 (ml64.exe) ml64.exe is given with Visual Studio 2005, Windows 2003 server DDK You can get Windows 2003 server DDK with ml64 and cl for AMD64 from http://www.microsoft.com/whdc/devtools/ddk/default.mspx for low price) |

All possible work was done for compatibility. Background --------------------- When adding ZIP64 support Mathias Svensson found that Even Rouault have added ZIP64 support for unzip.c into minizip for a open source project called gdal ( http://www.gdal.org/ ) That was used as a starting point. And after that ZIP64 support was added to zip.c some refactoring and code cleanup was also done. Changed from MiniZip 1.0 to MiniZip 1.1 --------------------------------------- * Added ZIP64 support for unzip ( by Even Rouault ) * Added ZIP64 support for zip ( by Mathias Svensson ) * Reverted some changed that Even Rouault did. * Bunch of patches received from Gulles Vollant that he received for MiniZip from various users. * Added unzip patch for BZIP Compression method (patch create by Daniel Borca) * Added BZIP Compress method for zip * Did some refactoring and code cleanup Credits Gilles Vollant - Original MiniZip author Even Rouault - ZIP64 unzip Support Daniel Borca - BZip Compression method support in unzip Mathias Svensson - ZIP64 zip support Mathias Svensson - BZip Compression method support in zip Resources ZipLayout http://result42.com/projects/ZipFileLayout Command line tool for Windows that shows the layout and information of the headers in a zip archive. Used when debugging and validating the creation of zip files using MiniZip64 ZIP App Note http://www.pkware.com/documents/casestudies/APPNOTE.TXT Zip File specification Notes. * To be able to use BZip compression method in zip64.c or unzip64.c the BZIP2 lib is needed and HAVE_BZIP2 need to be defined.

It was written as a demonstration of the .IR zlib (3) library and therefore lack many of the features of the .IR unzip (1) program. .SH OPTIONS A number of options are supported. With the exception of .BI \-d\ tempdir these must be supplied before any other arguments and are: .TP .BI \-l\ ,\ \-\-v List the files in the archive without extracting them. .TP .B \-o Overwrite files without prompting for confirmation. .TP .B \-x Extract files (default). .PP The .I zipfile argument is the name of the archive to process. The next argument can be used to specify a single file to extract from the archive. Lastly, the following option can be specified at the end of the command-line: .TP .BI \-d\ tempdir Extract the archive in the directory .I tempdir rather than the current directory. .SH SEE ALSO .BR minizip (1), .BR zlib (3), .BR unzip (1). .SH AUTHOR This program was written by Gilles Vollant. This manual page was written by Mark Brown <broonie@sirena.org.uk>. The -d tempdir option was added by Dirk Eddelbuettel <edd@debian.org>. |

See the accompanying file LICENSE, version 2000-Apr-09 or later (the contents of which are also included in zip.h) for terms of use.

Last revised: [see crypt.h] The encryption/decryption parts of this source code (as opposed to the non-echoing password parts) were originally written in Europe. The whole source package can be freely distributed, including from the USA. (Prior to January 2000, re-export from the US was a violation of US law.) This encryption code is a direct transcription of the algorithm from Roger Schlafly, described by Phil Katz in the file appnote.txt. This file (appnote.txt) is distributed with the PKZIP program (even in the version without encryption capabilities). ------------------------------------------------------------------------------------ Changes in unzip.c 2007-2008 - Even Rouault - Addition of cpl_unzGetCurrentFileZStreamPos 2007-2008 - Even Rouault - Decoration of symbol names unz* -> cpl_unz* 2007-2008 - Even Rouault - Remove old C style function prototypes 2007-2008 - Even Rouault - Add unzip support for ZIP64 Copyright (C) 2007-2008 Even Rouault Oct-2009 - Mathias Svensson - Removed cpl_* from symbol names (Even Rouault added them but since this is now moved to a new project (minizip64) I renamed them again). Oct-2009 - Mathias Svensson - Fixed problem if uncompressed size was > 4G and compressed size was <4G should only read the compressed/uncompressed size from the Zip64 format if the size from normal header was 0xFFFFFFFF Oct-2009 - Mathias Svensson - Applied some bug fixes from paches recived from Gilles Vollant Oct-2009 - Mathias Svensson - Applied support to unzip files with compression mathod BZIP2 (bzip2 lib is required) Patch created by Daniel Borca Jan-2010 - back to unzip and minizip 1.0 name scheme, with compatibility layer Copyright (C) 1998 - 2010 Gilles Vollant, Even Rouault, Mathias Svensson */ #include <stdio.h> #include <stdlib.h> #include <string.h> #ifndef NOUNCRYPT #define NOUNCRYPT #endif #include "zlib.h" #include "unzip.h" #ifdef STDC # include <stddef.h> # include <string.h> # include <stdlib.h> #endif #ifdef NO_ERRNO_H extern int errno; #else # include <errno.h> #endif #ifndef local # define local static #endif /* compile with -Dlocal if your debugger can't find static symbols */ #ifndef CASESENSITIVITYDEFAULT_NO # if !defined(unix) && !defined(CASESENSITIVITYDEFAULT_YES) # define CASESENSITIVITYDEFAULT_NO # endif #endif #ifndef UNZ_BUFSIZE #define UNZ_BUFSIZE (16384) #endif #ifndef UNZ_MAXFILENAMEINZIP #define UNZ_MAXFILENAMEINZIP (256) #endif #ifndef ALLOC # define ALLOC(size) (malloc(size)) #endif #ifndef TRYFREE # define TRYFREE(p) {if (p) free(p);} #endif #define SIZECENTRALDIRITEM (0x2e) #define SIZEZIPLOCALHEADER (0x1e) const char unz_copyright[] = " unzip 1.01 Copyright 1998-2004 Gilles Vollant - http://www.winimage.com/zLibDll"; /* unz_file_info_interntal contain internal info about a file in zipfile*/ typedef struct unz_file_info64_internal_s { ZPOS64_T offset_curfile;/* relative offset of local header 8 bytes */ } unz_file_info64_internal; /* file_in_zip_read_info_s contain internal information about a file in zipfile, when reading and decompress it */ typedef struct { char *read_buffer; /* internal buffer for compressed data */ z_stream stream; /* zLib stream structure for inflate */ #ifdef HAVE_BZIP2 bz_stream bstream; /* bzLib stream structure for bziped */ #endif ZPOS64_T pos_in_zipfile; /* position in byte on the zipfile, for fseek*/ uLong stream_initialised; /* flag set if stream structure is initialised*/ ZPOS64_T offset_local_extrafield;/* offset of the local extra field */ uInt size_local_extrafield;/* size of the local extra field */ ZPOS64_T pos_local_extrafield; /* position in the local extra field in read*/ ZPOS64_T total_out_64; uLong crc32; /* crc32 of all data uncompressed */ uLong crc32_wait; /* crc32 we must obtain after decompress all */ ZPOS64_T rest_read_compressed; /* number of byte to be decompressed */ ZPOS64_T rest_read_uncompressed;/*number of byte to be obtained after decomp*/ zlib_filefunc64_32_def z_filefunc; voidpf filestream; /* io structore of the zipfile */ uLong compression_method; /* compression method (0==store) */ ZPOS64_T byte_before_the_zipfile;/* byte before the zipfile, (>0 for sfx)*/ int raw; } file_in_zip64_read_info_s; /* unz64_s contain internal information about the zipfile */ typedef struct { zlib_filefunc64_32_def z_filefunc; int is64bitOpenFunction; voidpf filestream; /* io structore of the zipfile */ unz_global_info64 gi; /* public global information */ ZPOS64_T byte_before_the_zipfile;/* byte before the zipfile, (>0 for sfx)*/ ZPOS64_T num_file; /* number of the current file in the zipfile*/ ZPOS64_T pos_in_central_dir; /* pos of the current file in the central dir*/ ZPOS64_T current_file_ok; /* flag about the usability of the current file*/ ZPOS64_T central_pos; /* position of the beginning of the central dir*/ ZPOS64_T size_central_dir; /* size of the central directory */ ZPOS64_T offset_central_dir; /* offset of start of central directory with respect to the starting disk number */ unz_file_info64 cur_file_info; /* public info about the current file in zip*/ unz_file_info64_internal cur_file_info_internal; /* private info about it*/ file_in_zip64_read_info_s* pfile_in_zip_read; /* structure about the current file if we are decompressing it */ int encrypted; int isZip64; # ifndef NOUNCRYPT unsigned long keys[3]; /* keys defining the pseudo-random sequence */ const z_crc_t* pcrc_32_tab; # endif } unz64_s; #ifndef NOUNCRYPT #include "crypt.h" #endif /* =========================================================================== Read a byte from a gz_stream; update next_in and avail_in.

Modifications for Zip64 support Copyright (C) 2009-2010 Mathias Svensson ( http://result42.com ) For more info read MiniZip_info.txt Changes Oct-2009 - Mathias Svensson - Remove old C style function prototypes Oct-2009 - Mathias Svensson - Added Zip64 Support when creating new file archives Oct-2009 - Mathias Svensson - Did some code cleanup and refactoring to get better overview of some functions. Oct-2009 - Mathias Svensson - Added zipRemoveExtraInfoBlock to strip extra field data from its ZIP64 data It is used when recreting zip archive with RAW when deleting items from a zip. ZIP64 data is automatically added to items that needs it, and existing ZIP64 data need to be removed. Oct-2009 - Mathias Svensson - Added support for BZIP2 as compression mode (bzip2 lib is required) Jan-2010 - back to unzip and minizip 1.0 name scheme, with compatibility layer */ #include <stdio.h> #include <stdlib.h> #include <string.h> #include <time.h> #include "zlib.h" #include "zip.h" #ifdef STDC # include <stddef.h> # include <string.h> # include <stdlib.h> #endif #ifdef NO_ERRNO_H extern int errno;

Directory listing ================= zlibd32.mak makefile for Borland C++ example.pas usage example of zlib zlibpas.pas the Pascal interface to zlib readme.txt this file Compatibility notes =================== - Although the name "zlib" would have been more normal for the zlibpas unit, this name is already taken by Borland's ZLib unit. This is somehow unfortunate, because that unit is not a genuine interface to the full-fledged zlib functionality, but a suite of class wrappers around zlib streams. Other essential features, such as checksums, are missing. It would have been more appropriate for that unit to have a name like "ZStreams", or something similar. - The C and zlib-supplied types int, uInt, long, uLong, etc. are translated directly into Pascal types of similar sizes (Integer, LongInt, etc.), to avoid namespace pollution. In particular, there is no conversion of unsigned int into a Pascal unsigned integer. The Word type is non-portable and has the same size (16 bits) both in a 16-bit and in a 32-bit environment, unlike Integer. Even if there is a 32-bit Cardinal type, there is no real need for unsigned int in zlib under a 32-bit environment. - Except for the callbacks, the zlib function interfaces are assuming the calling convention normally used in Pascal (__pascal for DOS and Windows16, __fastcall for Windows32). Since the cdecl keyword is used, the old Turbo Pascal does not work with this interface. - The gz* function interfaces are not translated, to avoid interfacing problems with the C runtime library. Besides, gzprintf(gzFile file, const char *format, ...) cannot be translated into Pascal. Legal issues ============ The zlibpas interface is: Copyright (C) 1995-2003 Jean-loup Gailly and Mark Adler.

It does so more slowly than zlib, but the code is about one-fifth the size of the inflate code in zlib, and written to be very easy to read. Why I wrote this -- puff.c was written to document the deflate format unambiguously, by virtue of being working C code. It is meant to supplement RFC 1951, which formally describes the deflate format. I have received many questions on details of the deflate format, and I hope that reading this code will answer those questions. puff.c is heavily commented with details of the deflate format, especially those little nooks and cranies of the format that might not be obvious from a specification. puff.c may also be useful in applications where code size or memory usage is a very limited resource, and speed is not as important. How to use it -- Well, most likely you should just be reading puff.c and using zlib for actual applications, but if you must ... Include puff.h in your code, which provides this prototype: int puff(unsigned char *dest, /* pointer to destination pointer */ unsigned long *destlen, /* amount of output space */ unsigned char *source, /* pointer to source data pointer */ unsigned long *sourcelen); /* amount of input available */ Then you can call puff() to decompress a deflate stream that is in memory in its entirety at source, to a sufficiently sized block of memory for the decompressed data at dest. puff() is the only external symbol in puff.c The only C library functions that puff.c needs are setjmp() and longjmp(), which are used to simplify error checking in the code to improve readabilty. puff.c does no memory allocation, and uses less than 2K bytes off of the stack. If destlen is not enough space for the uncompressed data, then inflate will return an error without writing more than destlen bytes. Note that this means that in order to decompress the deflate data successfully, you need to know the size of the uncompressed data ahead of time. If needed, puff() can determine the size of the uncompressed data with no output space. This is done by passing dest equal to (unsigned char *)0. Then the initial value of *destlen is ignored and *destlen is set to the length of the uncompressed data. So if the size of the uncompressed data is not known, then two passes of puff() can be used--first to determine the size, and second to do the actual inflation after allocating the appropriate memory. Not pretty, but it works. (This is one of the reasons you should be using zlib.) The deflate format is self-terminating. If the deflate stream does not end in *sourcelen bytes, puff() will return an error without reading at or past endsource. On return, *sourcelen is updated to the amount of input data consumed, and *destlen is updated to the size of the uncompressed data. See the comments in puff.c for the possible return codes for puff(). |

conditions of distribution and use, see copyright notice in puff.h * version 2.3, 21 Jan 2013 * * puff.c is a simple inflate written to be an unambiguous way to specify the * deflate format. It is not written for speed but rather simplicity. As a * side benefit, this code might actually be useful when small code is more * important than speed, such as bootstrap applications. For typical deflate * data, zlib's inflate() is about four times as fast as puff(). zlib's * inflate compiles to around 20K on my machine, whereas puff.c compiles to * around 4K on my machine (a PowerPC using GNU cc). If the faster decode() * function here is used, then puff() is only twice as slow as zlib's * inflate(). * * All dynamically allocated memory comes from the stack. The stack required * is less than 2K bytes. This code is compatible with 16-bit int's and * assumes that long's are at least 32 bits. puff.c uses the short data type, * assumed to be 16 bits, for arrays in order to conserve memory. The code * works whether integers are stored big endian or little endian. * * In the comments below are "Format notes" that describe the inflate process * and document some of the less obvious aspects of the format.

Literals are simply Huffman * coded bytes. A length/distance pair is a coded length followed by a * coded distance to represent a string that occurs earlier in the * uncompressed data that occurs again at the current location. * * - Literals, lengths, and the end-of-block code are combined into a single * code of up to 286 symbols. They are 256 literals (0..255), 29 length * symbols (257..285), and the end-of-block symbol (256). * * - There are 256 possible lengths (3..258), and so 29 symbols are not enough * to represent all of those. Lengths 3..10 and 258 are in fact represented * by just a length symbol. Lengths 11..257 are represented as a symbol and * some number of extra bits that are added as an integer to the base length * of the length symbol. The number of extra bits is determined by the base * length symbol. These are in the static arrays below, lens[] for the base * lengths and lext[] for the corresponding number of extra bits. * * - The reason that 258 gets its own symbol is that the longest length is used * often in highly redundant files. Note that 258 can also be coded as the * base value 227 plus the maximum extra value of 31. While a good deflate * should never do this, it is not an error, and should be decoded properly. * * - If a length is decoded, including its extra bits if any, then it is * followed a distance code. There are up to 30 distance symbols. Again * there are many more possible distances (1..32768), so extra bits are added * to a base value represented by the symbol. The distances 1..4 get their * own symbol, but the rest require extra bits. The base distances and * corresponding number of extra bits are below in the static arrays dist[] * and dext[]. * * - Literal bytes are simply written to the output. A length/distance pair is * an instruction to copy previously uncompressed bytes to the output. The * copy is from distance bytes back in the output stream, copying for length * bytes. * * - Distances pointing before the beginning of the output data are not * permitted. * * - Overlapped copies, where the length is greater than the distance, are * allowed and common. For example, a distance of one and a length of 258 * simply copies the last byte 258 times. A distance of four and a length of * twelve copies the last four bytes three times. A simple forward copy * ignoring whether the length is greater than the distance or not implements * this correctly. You should not use memcpy() since its behavior is not * defined for overlapped arrays. You should not use memmove() or bcopy() * since though their behavior -is- defined for overlapping arrays, it is * defined to do the wrong thing in this case. */ local int codes(struct state *s, const struct huffman *lencode, const struct huffman *distcode) { int symbol; /* decoded symbol */ int len; /* length for copy */ unsigned dist; /* distance for copy */ static const short lens[29] = { /* Size base for length codes 257..285 */ 3, 4, 5, 6, 7, 8, 9, 10, 11, 13, 15, 17, 19, 23, 27, 31, 35, 43, 51, 59, 67, 83, 99, 115, 131, 163, 195, 227, 258}; static const short lext[29] = { /* Extra bits for length codes 257..285 */ 0, 0, 0, 0, 0, 0, 0, 0, 1, 1, 1, 1, 2, 2, 2, 2, 3, 3, 3, 3, 4, 4, 4, 4, 5, 5, 5, 5, 0}; static const short dists[30] = { /* Offset base for distance codes 0..29 */ 1, 2, 3, 4, 5, 7, 9, 13, 17, 25, 33, 49, 65, 97, 129, 193, 257, 385, 513, 769, 1025, 1537, 2049, 3073, 4097, 6145, 8193, 12289, 16385, 24577}; static const short dext[30] = { /* Extra bits for distance codes 0..29 */ 0, 0, 0, 0, 1, 1, 2, 2, 3, 3, 4, 4, 5, 5, 6, 6, 7, 7, 8, 8, 9, 9, 10, 10, 11, 11, 12, 12, 13, 13}; /* decode literals and length/distance pairs */ do { symbol = decode(s, lencode); if (symbol < 0) return symbol; /* invalid symbol */ if (symbol < 256) { /* literal: symbol is the byte */ /* write out the literal */ if (s->out != NIL) { if (s->outcnt == s->outlen) return 1; s->out[s->outcnt] = symbol; } s->outcnt++; } else if (symbol > 256) { /* length */ /* get and compute length */ symbol -= 257; if (symbol >= 29) return -10; /* invalid fixed code */ len = lens[symbol] + bits(s, lext[symbol]); /* get and check distance */ symbol = decode(s, distcode); if (symbol < 0) return symbol; /* invalid symbol */ dist = dists[symbol] + bits(s, dext[symbol]); #ifndef INFLATE_ALLOW_INVALID_DISTANCE_TOOFAR_ARRR if (dist > s->outcnt) return -11; /* distance too far back */ #endif /* copy length bytes from distance bytes back */ if (s->out != NIL) { if (s->outcnt + len > s->outlen) return 1; while (len--) { s->out[s->outcnt] = #ifdef INFLATE_ALLOW_INVALID_DISTANCE_TOOFAR_ARRR dist > s->outcnt ? 0 : #endif s->out[s->outcnt - dist]; s->outcnt++; } } else s->outcnt += len; } } while (symbol != 256); /* end of block symbol */ /* done with a valid fixed or dynamic block */ return 0; } /* * Process a fixed codes block. * * Format notes: * * - This block type can be useful for compressing small amounts of data for * which the size of the code descriptions in a dynamic block exceeds the * benefit of custom codes for that block.

New dynamic blocks allow the compressor to * rapidly adapt to changing data with new codes optimized for that data. * * - The codes used by the deflate format are "canonical", which means that * the actual bits of the codes are generated in an unambiguous way simply * from the number of bits in each code. Therefore the code descriptions * are simply a list of code lengths for each symbol. * * - The code lengths are stored in order for the symbols, so lengths are * provided for each of the literal/length symbols, and for each of the * distance symbols. * * - If a symbol is not used in the block, this is represented by a zero as * as the code length. This does not mean a zero-length code, but rather * that no code should be created for this symbol. There is no way in the * deflate format to represent a zero-length code. * * - The maximum number of bits in a code is 15, so the possible lengths for * any code are 1..15. * * - The fact that a length of zero is not permitted for a code has an * interesting consequence. Normally if only one symbol is used for a given * code, then in fact that code could be represented with zero bits. However * in deflate, that code has to be at least one bit. So for example, if * only a single distance base symbol appears in a block, then it will be * represented by a single code of length one, in particular one 0 bit. This * is an incomplete code, since if a 1 bit is received, it has no meaning, * and should result in an error. So incomplete distance codes of one symbol * should be permitted, and the receipt of invalid codes should be handled. * * - It is also possible to have a single literal/length code, but that code * must be the end-of-block code, since every dynamic block has one. This * is not the most efficient way to create an empty block (an empty fixed * block is fewer bits), but it is allowed by the format. So incomplete * literal/length codes of one symbol should also be permitted. * * - If there are only literal codes and no lengths, then there are no distance * codes. This is represented by one distance code with zero bits. * * - The list of up to 286 length/literal lengths and up to 30 distance lengths * are themselves compressed using Huffman codes and run-length encoding. In * the list of code lengths, a 0 symbol means no code, a 1..15 symbol means * that length, and the symbols 16, 17, and 18 are run-length instructions. * Each of 16, 17, and 18 are follwed by extra bits to define the length of * the run. 16 copies the last length 3 to 6 times. 17 represents 3 to 10 * zero lengths, and 18 represents 11 to 138 zero lengths. Unused symbols * are common, hence the special coding for zero lengths. * * - The symbols for 0..18 are Huffman coded, and so that code must be * described first. This is simply a sequence of up to 19 three-bit values * representing no code (0) or the code length for that symbol (1..7). * * - A dynamic block starts with three fixed-size counts from which is computed * the number of literal/length code lengths, the number of distance code * lengths, and the number of code length code lengths (ok, you come up with * a better name!) in the code descriptions. For the literal/length and * distance codes, lengths after those provided are considered zero, i.e. no * code. The code length code lengths are received in a permuted order (see * the order[] array below) to make a short code length code length list more * likely. As it turns out, very short and very long codes are less likely * to be seen in a dynamic code description, hence what may appear initially * to be a peculiar ordering. * * - Given the number of literal/length code lengths (nlen) and distance code * lengths (ndist), then they are treated as one long list of nlen + ndist * code lengths. Therefore run-length coding can and often does cross the * boundary between the two sets of lengths. * * - So to summarize, the code description at the start of a dynamic block is * three counts for the number of code lengths for the literal/length codes, * the distance codes, and the code length codes. This is followed by the * code length code lengths, three bits each. This is used to construct the * code length code which is used to read the remainder of the lengths. Then * the literal/length code lengths and distance lengths are read as a single * set of lengths using the code length codes. Codes are constructed from * the resulting two sets of lengths, and then finally you can start * decoding actual compressed data in the block. * * - For reference, a "typical" size for the code description in a dynamic * block is around 80 bytes. */ local int dynamic(struct state *s) { int nlen, ndist, ncode; /* number of lengths in descriptor */ int index; /* index of lengths[] */ int err; /* construct() return value */ short lengths[MAXCODES]; /* descriptor code lengths */ short lencnt[MAXBITS+1], lensym[MAXLCODES]; /* lencode memory */ short distcnt[MAXBITS+1], distsym[MAXDCODES]; /* distcode memory */ struct huffman lencode, distcode; /* length and distance codes */ static const short order[19] = /* permutation of code length codes */ {16, 17, 18, 0, 8, 7, 9, 6, 10, 5, 11, 4, 12, 3, 13, 2, 14, 1, 15}; /* construct lencode and distcode */ lencode.count = lencnt; lencode.symbol = lensym; distcode.count = distcnt; distcode.symbol = distsym; /* get number of lengths in each table, check lengths */ nlen = bits(s, 5) + 257; ndist = bits(s, 5) + 1; ncode = bits(s, 4) + 4; if (nlen > MAXLCODES || ndist > MAXDCODES) return -3; /* bad counts */ /* read code length code lengths (really), missing lengths are zero */ for (index = 0; index < ncode; index++) lengths[order[index]] = bits(s, 3); for (; index < 19; index++) lengths[order[index]] = 0; /* build huffman table for code lengths codes (use lencode temporarily) */ err = construct(&lencode, lengths, 19); if (err != 0) /* require complete code set here */ return -4; /* read length/literal and distance code length tables */ index = 0; while (index < nlen + ndist) { int symbol; /* decoded value */ int len; /* last length to repeat */ symbol = decode(s, &lencode); if (symbol < 0) return symbol; /* invalid symbol */ if (symbol < 16) /* length in 0..15 */ lengths[index++] = symbol; else { /* repeat instruction */ len = 0; /* assume repeating zeros */ if (symbol == 16) { /* repeat last length 3..6 times */ if (index == 0) return -5; /* no last length! */ len = lengths[index - 1]; /* last length */ symbol = 3 + bits(s, 2); } else if (symbol == 17) /* repeat zero 3..10 times */ symbol = 3 + bits(s, 3); else /* == 18, repeat zero 11..138 times */ symbol = 11 + bits(s, 7); if (index + symbol > nlen + ndist) return -6; /* too many lengths! */ while (symbol--) /* repeat last or zero symbol times */ lengths[index++] = len; } } /* check for end-of-block code -- there better be one! */ if (lengths[256] == 0) return -9; /* build huffman table for literal/length codes */ err = construct(&lencode, lengths, nlen); if (err && (err < 0 || nlen != lencode.count[0] + lencode.count[1])) return -7; /* incomplete code ok only for single length 1 code */ /* build huffman table for distance codes */ err = construct(&distcode, lengths + nlen, ndist); if (err && (err < 0 || ndist != distcode.count[0] + distcode.count[1])) return -8; /* incomplete code ok only for single length 1 code */ /* decode data until end-of-block code */ return codes(s, &lencode, &distcode); } /* * Inflate source to dest.

Build instructions for Visual Studio 2008 (32 bits or 64 bits) -------------------------------------------------------------- - Decompress current zlib, including all contrib/* files - Compile assembly code (with Visual Studio Command Prompt) by running: bld_ml64.bat (in contrib\masmx64) bld_ml32.bat (in contrib\masmx86) - Open contrib\vstudio\vc9\zlibvc.sln with Microsoft Visual C++ 2008 - Or run: vcbuild /rebuild contrib\vstudio\vc9\zlibvc.sln "Release|Win32" Build instructions for Visual Studio 2010 (32 bits or 64 bits) -------------------------------------------------------------- - Decompress current zlib, including all contrib/* files - Open contrib\vstudio\vc10\zlibvc.sln with Microsoft Visual C++ 2010 Build instructions for Visual Studio 2012 (32 bits or 64 bits) -------------------------------------------------------------- - Decompress current zlib, including all contrib/* files - Open contrib\vstudio\vc11\zlibvc.sln with Microsoft Visual C++ 2012 Build instructions for Visual Studio 2013 (32 bits or 64 bits) -------------------------------------------------------------- - Decompress current zlib, including all contrib/* files - Open contrib\vstudio\vc12\zlibvc.sln with Microsoft Visual C++ 2013 Build instructions for Visual Studio 2015 (32 bits or 64 bits) -------------------------------------------------------------- - Decompress current zlib, including all contrib/* files - Open contrib\vstudio\vc14\zlibvc.sln with Microsoft Visual C++ 2015 Important --------- - To use zlibwapi.dll in your application, you must define the macro ZLIB_WINAPI when compiling your application's source files. Additional notes ---------------- - This DLL, named zlibwapi.dll, is compatible to the old zlib.dll built by Gilles Vollant from the zlib 1.1.x sources, and distributed at http://www.winimage.com/zLibDll It uses the WINAPI calling convention for the exported functions, and includes the minizip functionality. If your application needs that particular build of zlib.dll, you can rename zlibwapi.dll to zlib.dll. - The new DLL was renamed because there exist several incompatible versions of zlib.dll on the Internet. - There is also an official DLL build of zlib, named zlib1.dll. This one is exporting the functions using the CDECL convention. See the file win32\DLL_FAQ.txt found in this zlib distribution. - There used to be a ZLIB_DLL macro in zlib 1.1.x, but now this symbol has a slightly different effect. To avoid compatibility problems, do not define it here. Gilles Vollant info@winimage.com Visual Studio 2013 and 2015 Projects from Sean Hunt seandhunt_7@yahoo.com |

Polynomials over GF(2) are represented in binary, one bit per coefficient, with the lowest powers in the most significant bit. Then adding polynomials is just exclusive-or, and multiplying a polynomial by x is a right shift by one. If we call the above polynomial p, and represent a byte as the polynomial q, also with the lowest power in the most significant bit (so the byte 0xb1 is the polynomial x^7+x^3+x+1), then the CRC is (q*x^32) mod p, where a mod b means the remainder after dividing a by b. This calculation is done using the shift-register method of multiplying and taking the remainder. The register is initialized to zero, and for each incoming bit, x^32 is added mod p to the register if the bit is a one (where x^32 mod p is p+x^32 = x^26+...+1), and the register is multiplied mod p by x (which is shifting right by one and adding x^32 mod p if the bit shifted out is a one). We start with the highest power (least significant bit) of q and repeat for all eight bits of q. The first table is simply the CRC of all possible eight bit values. This is all the information needed to generate CRCs on data a byte at a time for all combinations of CRC register values and incoming bytes. The remaining tables allow for word-at-a-time CRC calculation for both big-endian and little- endian machines, where a word is four bytes. */ local void make_crc_table() { z_crc_t c; int n, k; z_crc_t poly; /* polynomial exclusive-or pattern */ /* terms of polynomial defining this crc (except x^32): */ static volatile int first = 1; /* flag to limit concurrent making */ static const unsigned char p[] = {0,1,2,4,5,7,8,10,11,12,16,22,23,26}; /* See if another task is already doing this (not thread-safe, but better than nothing -- significantly reduces duration of vulnerability in case the advice about DYNAMIC_CRC_TABLE is ignored) */ if (first) { first = 0; /* make exclusive-or pattern from polynomial (0xedb88320UL) */ poly = 0; for (n = 0; n < (int)(sizeof(p)/sizeof(unsigned char)); n++) poly |= (z_crc_t)1 << (31 - p[n]); /* generate a crc for every 8-bit value */ for (n = 0; n < 256; n++) { c = (z_crc_t)n; for (k = 0; k < 8; k++) c = c & 1 ? poly ^ (c >> 1) : c >> 1; crc_table[0][n] = c; } #ifdef BYFOUR /* generate crc for each value followed by one, two, and three zeros, and then the byte reversal of those as well as the first table */ for (n = 0; n < 256; n++) { c = crc_table[0][n]; crc_table[4][n] = ZSWAP32(c); for (k = 1; k < 4; k++) { c = crc_table[0][c & 0xff] ^ (c >> 8); crc_table[k][n] = c; crc_table[k + 4][n] = ZSWAP32(c); } } #endif /* BYFOUR */ crc_table_empty = 0; } else { /* not first */ /* wait for the other guy to finish (not efficient, but rare) */ while (crc_table_empty) ; } #ifdef MAKECRCH /* write out CRC tables to crc32.h */ { FILE *out; out = fopen("crc32.h", "w"); if (out == NULL) return; fprintf(out, "/* crc32.h -- tables for rapid CRC calculation\n"); fprintf(out, " * Generated automatically by crc32.c\n */\n\n"); fprintf(out, "local const z_crc_t FAR "); fprintf(out, "crc_table[TBLS][256] =\n{\n {\n"); write_table(out, crc_table[0]); # ifdef BYFOUR fprintf(out, "#ifdef BYFOUR\n"); for (k = 1; k < 8; k++) { fprintf(out, " },\n {\n"); write_table(out, crc_table[k]); } fprintf(out, "#endif\n"); # endif /* BYFOUR */ fprintf(out, " }\n};\n"); fclose(out); } #endif /* MAKECRCH */ } #ifdef MAKECRCH local void write_table(out, table) FILE *out; const z_crc_t FAR *table; { int n; for (n = 0; n < 256; n++) fprintf(out, "%s0x%08lxUL%s", n % 5 ?

copyright notice in zlib.h */ /* * ALGORITHM * * The "deflation" process depends on being able to identify portions * of the input text which are identical to earlier input (within a * sliding window trailing behind the input currently being processed). * * The most straightforward technique turns out to be the fastest for * most input files: try all possible matches and select the longest. * The key feature of this algorithm is that insertions into the string * dictionary are very simple and thus fast, and deletions are avoided * completely. Insertions are performed at each input character, whereas * string matches are performed only when the previous match ends. So it * is preferable to spend more time in matches to allow very fast string * insertions and avoid deletions. The matching algorithm for small * strings is inspired from that of Rabin & Karp. A brute force approach * is used to find longer strings when a small match has been found. * A similar algorithm is used in comic (by Jan-Mark Wams) and freeze * (by Leonid Broukhis). * A previous version of this file used a more sophisticated algorithm * (by Fiala and Greene) which is guaranteed to run in linear amortized * time, but has a larger average cost, uses more memory and is patented. * However the F&G algorithm may be faster for some highly redundant * files if the parameter max_chain_length (described below) is too large. * * ACKNOWLEDGEMENTS * * The idea of lazy evaluation of matches is due to Jan-Mark Wams, and * I found it in 'freeze' written by Leonid Broukhis. * Thanks to many people for bug reports and testing. * * REFERENCES * * Deutsch, L.P.,"DEFLATE Compressed Data Format Specification". * Available in http://tools.ietf.org/html/rfc1951 * * A description of the Rabin and Karp algorithm is given in the book * "Algorithms" by R. Sedgewick, Addison-Wesley, p252. * * Fiala,E.R., and Greene,D.H. * Data Compression with Finite Windows, Comm.ACM, 32,4 (1989) 490-595 * */ /* @(#) $Id$ */ #include "deflate.h" const char deflate_copyright[] = " deflate 1.2.11 Copyright 1995-2017 Jean-loup Gailly and Mark Adler "; /* If you use the zlib library in a product, an acknowledgment is welcome in the documentation of your product.

Only complete Huffman codes are counted. Two codes are considered distinct if the vectors of the number of codes per length are not identical. So permutations of the symbol assignments result in the same code for the counting, as do permutations of the assignments of the bit values to the codes (i.e. only canonical codes are counted). We build a code from shorter to longer lengths, determining how many symbols are coded at each length. At each step, we have how many symbols remain to be coded, what the last code length used was, and how many bit patterns of that length remain unused. Then we add one to the code length and double the number of unused patterns to graduate to the next code length. We then assign all portions of the remaining symbols to that code length that preserve the properties of a correct and eventually complete code. Those properties are: we cannot use more bit patterns than are available; and when all the symbols are used, there are exactly zero possible bit patterns remaining. The inflate Huffman decoding algorithm uses two-level lookup tables for speed. There is a single first-level table to decode codes up to root bits in length (root == 9 in the current inflate implementation). The table has 1 << root entries and is indexed by the next root bits of input. Codes shorter than root bits have replicated table entries, so that the correct entry is pointed to regardless of the bits that follow the short code. If the code is longer than root bits, then the table entry points to a second- level table. The size of that table is determined by the longest code with that root-bit prefix. If that longest code has length len, then the table has size 1 << (len - root), to index the remaining bits in that set of codes. Each subsequent root-bit prefix then has its own sub-table. The total number of table entries required by the code is calculated incrementally as the number of codes at each bit length is populated. When all of the codes are shorter than root bits, then root is reduced to the longest code length, resulting in a single, smaller, one-level table. The inflate algorithm also provides for small values of root (relative to the log2 of the number of symbols), where the shortest code has more bits than root. In that case, root is increased to the length of the shortest code. This program, by design, does not handle that case, so it is verified that the number of symbols is less than 2^(root + 1). In order to speed up the examination (by about ten orders of magnitude for the default arguments), the intermediate states in the build-up of a code are remembered and previously visited branches are pruned. The memory required for this will increase rapidly with the total number of symbols and the maximum code length in bits. However this is a very small price to pay for the vast speedup. First, all of the possible Huffman codes are counted, and reachable intermediate states are noted by a non-zero count in a saved-results array. Second, the intermediate states that lead to (root + 1) bit or longer codes are used to look at all sub-codes from those junctures for their inflate memory usage. (The amount of memory used is not affected by the number of codes of root bits or less in length.) Third, the visited states in the construction of those sub-codes and the associated calculation of the table size is recalled in order to avoid recalculating from the same juncture. Beginning the code examination at (root + 1) bit codes, which is enabled by identifying the reachable nodes, accounts for about six of the orders of magnitude of improvement for the default arguments. About another four orders of magnitude come from not revisiting previous states. Out of approximately 2x10^16 possible Huffman codes, only about 2x10^6 sub-codes need to be examined to cover all of the possible table memory usage cases for the default arguments of 286 symbols limited to 15-bit codes. Note that an unsigned long long type is used for counting. It is quite easy to exceed the capacity of an eight-byte integer with a large number of symbols and a large maximum code length, so multiple-precision arithmetic would need to replace the unsigned long long arithmetic in that case. This program will abort if an overflow occurs. The big_t type identifies where the counting takes place. An unsigned long long type is also used for calculating the number of possible codes remaining at the maximum length. This limits the maximum code length to the number of bits in a long long minus the number of bits needed to represent the symbols in a flat code. The code_t type identifies where the bit pattern counting takes place. */ #include <stdio.h> #include <stdlib.h> #include <string.h> #include <assert.h> #define local static /* special data types */ typedef unsigned long long big_t; /* type for code counting */ typedef unsigned long long code_t; /* type for bit pattern counting */ struct tab { /* type for been here check */ size_t len; /* length of bit vector in char's */ char *vec; /* allocated bit vector */ }; /* The array for saving results, num[], is indexed with this triplet: syms: number of symbols remaining to code left: number of available bit patterns at length len len: number of bits in the codes currently being assigned Those indices are constrained thusly when saving results: syms: 3..totsym (totsym == total symbols to code) left: 2..syms - 1, but only the evens (so syms == 8 -> 2, 4, 6) len: 1..max - 1 (max == maximum code length in bits) syms == 2 is not saved since that immediately leads to a single code. left must be even, since it represents the number of available bit patterns at the current length, which is double the number at the previous length. left ends at syms-1 since left == syms immediately results in a single code. (left > sym is not allowed since that would result in an incomplete code.) len is less than max, since the code completes immediately when len == max. The offset into the array is calculated for the three indices with the first one (syms) being outermost, and the last one (len) being innermost. We build the array with length max-1 lists for the len index, with syms-3 of those for each symbol. There are totsym-2 of those, with each one varying in length as a function of sym. See the calculation of index in count() for the index, and the calculation of size in main() for the size of the array. For the deflate example of 286 symbols limited to 15-bit codes, the array has 284,284 entries, taking up 2.17 MB for an 8-byte big_t.

Each element in the array is further indexed by the (mem, rem) doublet, where mem is the amount of inflate table space used so far, and rem is the remaining unused entries in the current inflate sub-table. Each indexed element is simply one bit indicating whether the state has been visited or not. Since the ranges for mem and rem are not known a priori, each bit vector is of a variable size, and grows as needed to accommodate the visited states. mem and rem are used to calculate a single index in a triangular array. Since the range of mem is expected in the default case to be about ten times larger than the range of rem, the array is skewed to reduce the memory usage, with eight times the range for mem than for rem. See the calculations for offset and bit in beenhere() for the details.

The first pass generates enough deflate blocks to produce output to fill the requested output size plus a specfied excess amount (see the EXCESS define below). The last deflate block may go quite a bit past that, but is discarded. The second pass decompresses and recompresses just the compressed data that fit in the requested plus excess sized buffer. The deflate process is terminated after that amount of input, which is less than the amount consumed on the first pass. The last deflate block of the result will be of a comparable size to the final product, so that the header for that deflate block and the compression ratio for that block will be about the same as in the final product. The third compression pass decompresses the result of the second step, but only the compressed data up to the requested size minus an amount to allow the compressed stream to complete (see the MARGIN define below). That will result in a final compressed stream whose length is less than or equal to the requested size. Assuming sufficient input and a requested size greater than a few hundred bytes, the shortfall will typically be less than ten bytes. If the input is short enough that the first compression completes before filling the requested output size, then that compressed stream is return with no recompression. EXCESS is chosen to be just greater than the shortfall seen in a two pass approach similar to the above. That shortfall is due to the last deflate block compressing more efficiently with a smaller header on the second pass. EXCESS is set to be large enough so that there is enough uncompressed data for the second pass to fill out the requested size, and small enough so that the final deflate block of the second pass will be close in size to the final deflate block of the third and final pass. MARGIN is chosen to be just large enough to assure that the final compression has enough room to complete in all cases. */ #include <stdio.h> #include <stdlib.h> #include <assert.h> #include "zlib.h" #define local static /* print nastygram and leave */ local void quit(char *why) { fprintf(stderr, "fitblk abort: %s\n", why); exit(1); } #define RAWLEN 4096 /* intermediate uncompressed buffer size */ /* compress from file to def until provided buffer is full or end of input reached; return last deflate() return value, or Z_ERRNO if there was read error on the file */ local int partcompress(FILE *in, z_streamp def) { int ret, flush; unsigned char raw[RAWLEN]; flush = Z_NO_FLUSH; do { def->avail_in = fread(raw, 1, RAWLEN, in); if (ferror(in)) return Z_ERRNO; def->next_in = raw; if (feof(in)) flush = Z_FINISH; ret = deflate(def, flush); assert(ret != Z_STREAM_ERROR); } while (def->avail_out != 0 && flush == Z_NO_FLUSH); return ret; } /* recompress from inf's input to def's output; the input for inf and the output for def are set in those structures before calling; return last deflate() return value, or Z_MEM_ERROR if inflate() was not able to allocate enough memory when it needed to */ local int recompress(z_streamp inf, z_streamp def) { int ret, flush; unsigned char raw[RAWLEN]; flush = Z_NO_FLUSH; do { /* decompress */ inf->avail_out = RAWLEN; inf->next_out = raw; ret = inflate(inf, Z_NO_FLUSH); assert(ret != Z_STREAM_ERROR && ret != Z_DATA_ERROR && ret != Z_NEED_DICT); if (ret == Z_MEM_ERROR) return ret; /* compress what was decompresed until done or no room */ def->avail_in = RAWLEN - inf->avail_out; def->next_in = raw; if (inf->avail_out != 0) flush = Z_FINISH; ret = deflate(def, flush); assert(ret != Z_STREAM_ERROR); } while (ret != Z_STREAM_END && def->avail_out != 0); return ret; } #define EXCESS 256 /* empirically determined stream overage */ #define MARGIN 8 /* amount to back off for completion */ /* compress from stdin to fixed-size block on stdout */ int main(int argc, char **argv) { int ret; /* return code */ unsigned size; /* requested fixed output block size */ unsigned have; /* bytes written by deflate() call */ unsigned char *blk; /* intermediate and final stream */ unsigned char *tmp; /* close to desired size stream */ z_stream def, inf; /* zlib deflate and inflate states */ /* get requested output size */ if (argc != 2) quit("need one argument: size of output block"); ret = strtol(argv[1], argv + 1, 10); if (argv[1][0] != 0) quit("argument must be a number"); if (ret < 8) /* 8 is minimum zlib stream size */ quit("need positive size of 8 or greater"); size = (unsigned)ret; /* allocate memory for buffers and compression engine */ blk = malloc(size + EXCESS); def.zalloc = Z_NULL; def.zfree = Z_NULL; def.opaque = Z_NULL; ret = deflateInit(&def, Z_DEFAULT_COMPRESSION); if (ret != Z_OK || blk == NULL) quit("out of memory"); /* compress from stdin until output full, or no more input */ def.avail_out = size + EXCESS; def.next_out = blk; ret = partcompress(stdin, &def); if (ret == Z_ERRNO) quit("error reading input"); /* if it all fit, then size was undersubscribed -- done!

Unlike gzip, gun allows an empty file on input, and will produce no error writing an empty output file. gun will also decompress files made by Unix compress, which uses LZW compression. These files are automatically detected by virtue of their magic header bytes. Since the end of Unix compress stream is marked by the end-of-file, they cannot be concantenated. If a Unix compress stream is encountered in an input file, it is the last stream in that file. Like gunzip and uncompress, the file attributes of the original compressed file are maintained in the final uncompressed file, to the extent that the user permissions allow it. On my Mac OS X PowerPC G4, gun is almost twice as fast as gunzip (version 1.2.4) is on the same file, when gun is linked with zlib 1.2.2. Also the LZW decompression provided by gun is about twice as fast as the standard Unix uncompress command. */ /* external functions and related types and constants */ #include <stdio.h> /* fprintf() */ #include <stdlib.h> /* malloc(), free() */ #include <string.h> /* strerror(), strcmp(), strlen(), memcpy() */ #include <errno.h> /* errno */ #include <fcntl.h> /* open() */ #include <unistd.h> /* read(), write(), close(), chown(), unlink() */ #include <sys/types.h> #include <sys/stat.h> /* stat(), chmod() */ #include <utime.h> /* utime() */ #include "zlib.h" /* inflateBackInit(), inflateBack(), */ /* inflateBackEnd(), crc32() */ /* function declaration */ #define local static /* buffer constants */ #define SIZE 32768U /* input and output buffer sizes */ #define PIECE 16384 /* limits i/o chunks for 16-bit int case */ /* structure for infback() to pass to input function in() -- it maintains the input file and a buffer of size SIZE */ struct ind { int infile; unsigned char *inbuf; }; /* Load input buffer, assumed to be empty, and return bytes loaded and a pointer to them. read() is called until the buffer is full, or until it returns end-of-file or error.

The gzip file is written to directly, to avoid copying that file, in case it's large. Note that this results in the unfriendly behavior that if gzappend fails, the gzip file is corrupted. This program was written to illustrate the use of the new Z_BLOCK option of zlib 1.2.x's inflate() function. This option returns from inflate() at each block boundary to facilitate locating and modifying the last block bit at the start of the final deflate block. Also whether using Z_BLOCK or not, another required feature of zlib 1.2.x is that inflate() now provides the number of unusued bits in the last input byte used. gzappend will not work with versions of zlib earlier than 1.2.1. gzappend first decompresses the gzip file internally, discarding all but the last 32K of uncompressed data, and noting the location of the last block bit and the number of unused bits in the last byte of the compressed data. The gzip trailer containing the CRC-32 and length of the uncompressed data is verified. This trailer will be later overwritten. Then the last block bit is cleared by seeking back in the file and rewriting the byte that contains it. Seeking forward, the last byte of the compressed data is saved along with the number of unused bits to initialize deflate. A deflate process is initialized, using the last 32K of the uncompressed data from the gzip file to initialize the dictionary. If the total uncompressed data was less than 32K, then all of it is used to initialize the dictionary. The deflate output bit buffer is also initialized with the last bits from the original deflate stream. From here on, the data to append is simply compressed using deflate, and written to the gzip file. When that is complete, the new CRC-32 and uncompressed length are written as the trailer of the gzip file. */ #include <stdio.h> #include <stdlib.h> #include <string.h> #include <fcntl.h> #include <unistd.h> #include "zlib.h" #define local static #define LGCHUNK 14 #define CHUNK (1U << LGCHUNK) #define DSIZE 32768U /* print an error message and terminate with extreme prejudice */ local void bye(char *msg1, char *msg2) { fprintf(stderr, "gzappend error: %s%s\n", msg1, msg2);

efficient both in execution time and compression ratio. The strategy is to write the short strings in an uncompressed form to the end of the gzip file, only compressing when the amount of uncompressed data has reached a given threshold. gzlog also provides protection against interruptions in the process due to system crashes. The status of the operation is recorded in an extra field in the gzip file, and is only updated once the gzip file is brought to a valid state. The last data to be appended or compressed is saved in an auxiliary file, so that if the operation is interrupted, it can be completed the next time an append operation is attempted. gzlog maintains another auxiliary file with the last 32K of data from the compressed portion, which is preloaded for the compression of the subsequent data. This minimizes the impact to the compression ratio of appending. */ /* Operations Concept: Files (log name "foo"): foo.gz -- gzip file with the complete log foo.add -- last message to append or last data to compress foo.dict -- dictionary of the last 32K of data for next compression foo.temp -- temporary dictionary file for compression after this one foo.lock -- lock file for reading and writing the other files foo.repairs -- log file for log file recovery operations (not compressed) gzip file structure: - fixed-length (no file name) header with extra field (see below) - compressed data ending initially with empty stored block - uncompressed data filling out originally empty stored block and subsequent stored blocks as needed (16K max each) - gzip trailer - no junk at end (no other gzip streams) When appending data, the information in the first three items above plus the foo.add file are sufficient to recover an interrupted append operation. The extra field has the necessary information to restore the start of the last stored block and determine where to append the data in the foo.add file, as well as the crc and length of the gzip data before the append operation. The foo.add file is created before the gzip file is marked for append, and deleted after the gzip file is marked as complete. So if the append operation is interrupted, the data to add will still be there. If due to some external force, the foo.add file gets deleted between when the append operation was interrupted and when recovery is attempted, the gzip file will still be restored, but without the appended data. When compressing data, the information in the first two items above plus the foo.add file are sufficient to recover an interrupted compress operation. The extra field has the necessary information to find the end of the compressed data, and contains both the crc and length of just the compressed data and of the complete set of data including the contents of the foo.add file. Again, the foo.add file is maintained during the compress operation in case of an interruption. If in the unlikely event the foo.add file with the data to be compressed is missing due to some external force, a gzip file with just the previous compressed data will be reconstructed. In this case, all of the data that was to be compressed is lost (approximately one megabyte). This will not occur if all that happened was an interruption of the compress operation. The third state that is marked is the replacement of the old dictionary with the new dictionary after a compress operation. Once compression is complete, the gzip file is marked as being in the replace state. This completes the gzip file, so an interrupt after being so marked does not result in recompression. Then the dictionary file is replaced, and the gzip file is marked as completed. This state prevents the possibility of restarting compression with the wrong dictionary file. All three operations are wrapped by a lock/unlock procedure. In order to gain exclusive access to the log files, first a foo.lock file must be exclusively created. When all operations are complete, the lock is released by deleting the foo.lock file. If when attempting to create the lock file, it already exists and the modify time of the lock file is more than five minutes old (set by the PATIENCE define below), then the old lock file is considered stale and deleted, and the exclusive creation of the lock file is retried. To assure that there are no false assessments of the staleness of the lock file, the operations periodically touch the lock file to update the modified date. Following is the definition of the extra field with all of the information required to enable the above append and compress operations and their recovery if interrupted. Multi-byte values are stored little endian (consistent with the gzip format). File pointers are eight bytes long. The crc's and lengths for the gzip trailer are four bytes long. (Note that the length at the end of a gzip file is used for error checking only, and for large files is actually the length modulo 2^32.) The stored block length is two bytes long. The gzip extra field two-byte identification is "ap" for append. It is assumed that writing the extra field to the file is an "atomic" operation. That is, either all of the extra field is written to the file, or none of it is, if the operation is interrupted right at the point of updating the extra field. This is a reasonable assumption, since the extra field is within the first 52 bytes of the file, which is smaller than any expected block size for a mass storage device (usually 512 bytes or larger). Extra field (35 bytes): - Pointer to first stored block length -- this points to the two-byte length of the first stored block, which is followed by the two-byte, one's complement of that length. The stored block length is preceded by the three-bit header of the stored block, which is the actual start of the stored block in the deflate format. See the bit offset field below. - Pointer to the last stored block length. This is the same as above, but for the last stored block of the uncompressed data in the gzip file. Initially this is the same as the first stored block length pointer. When the stored block gets to 16K (see the MAX_STORE define), then a new stored block as added, at which point the last stored block length pointer is different from the first stored block length pointer. When they are different, the first bit of the last stored block header is eight bits, or one byte back from the block length. - Compressed data crc and length. This is the crc and length of the data that is in the compressed portion of the deflate stream. These are used only in the event that the foo.add file containing the data to compress is lost after a compress operation is interrupted. - Total data crc and length. This is the crc and length of all of the data stored in the gzip file, compressed and uncompressed. It is used to reconstruct the gzip trailer when compressing, as well as when recovering interrupted operations. - Final stored block length. This is used to quickly find where to append, and allows the restoration of the original final stored block state when an append operation is interrupted. - First stored block start as the number of bits back from the final stored block first length byte. This value is in the range of 3..10, and is stored as the low three bits of the final byte of the extra field after subtracting three (0..7). This allows the last-block bit of the stored block header to be updated when a new stored block is added, for the case when the first stored block and the last stored block are the same. (When they are different, the numbers of bits back is known to be eight.) This also allows for new compressed data to be appended to the old compressed data in the compress operation, overwriting the previous first stored block, or for the compressed data to be terminated and a valid gzip file reconstructed on the off chance that a compression operation was interrupted and the data to compress in the foo.add file was deleted. - The operation in process. This is the next two bits in the last byte (the bits under the mask 0x18). The are interpreted as 0: nothing in process, 1: append in process, 2: compress in process, 3: replace in process. - The top three bits of the last byte in the extra field are reserved and are currently set to zero. Main procedure: - Exclusively create the foo.lock file using the O_CREAT and O_EXCL modes of the system open() call. If the modify time of an existing lock file is more than PATIENCE seconds old, then the lock file is deleted and the exclusive create is retried. - Load the extra field from the foo.gz file, and see if an operation was in progress but not completed. If so, apply the recovery procedure below. - Perform the append procedure with the provided data. - If the uncompressed data in the foo.gz file is 1MB or more, apply the compress procedure. - Delete the foo.lock file. Append procedure: - Put what to append in the foo.add file so that the operation can be restarted if this procedure is interrupted. - Mark the foo.gz extra field with the append operation in progress. + Restore the original last-block bit and stored block length of the last stored block from the information in the extra field, in case a previous append operation was interrupted. - Append the provided data to the last stored block, creating new stored blocks as needed and updating the stored blocks last-block bits and lengths. - Update the crc and length with the new data, and write the gzip trailer. - Write over the extra field (with a single write operation) with the new pointers, lengths, and crc's, and mark the gzip file as not in process. Though there is still a foo.add file, it will be ignored since nothing is in process. If a foo.add file is leftover from a previously completed operation, it is truncated when writing new data to it. - Delete the foo.add file. Compress and replace procedures: - Read all of the uncompressed data in the stored blocks in foo.gz and write it to foo.add. Also write foo.temp with the last 32K of that data to provide a dictionary for the next invocation of this procedure. - Rewrite the extra field marking foo.gz with a compression in process. * If there is no data provided to compress (due to a missing foo.add file when recovering), reconstruct and truncate the foo.gz file to contain only the previous compressed data and proceed to the step after the next one. Otherwise ... - Compress the data with the dictionary in foo.dict, and write to the foo.gz file starting at the bit immediately following the last previously compressed block. If there is no foo.dict, proceed anyway with the compression at slightly reduced efficiency. (For the foo.dict file to be missing requires some external failure beyond simply the interruption of a compress operation.) During this process, the foo.lock file is periodically touched to assure that that file is not considered stale by another process before we're done. The deflation is terminated with a non-last empty static block (10 bits long), that is then located and written over by a last-bit-set empty stored block. - Append the crc and length of the data in the gzip file (previously calculated during the append operations). - Write over the extra field with the updated stored block offsets, bits back, crc's, and lengths, and mark foo.gz as in process for a replacement of the dictionary. @ Delete the foo.add file. - Replace foo.dict with foo.temp. - Write over the extra field, marking foo.gz as complete. Recovery procedure: - If not a replace recovery, read in the foo.add file, and provide that data to the appropriate recovery below. If there is no foo.add file, provide a zero data length to the recovery. In that case, the append recovery restores the foo.gz to the previous compressed + uncompressed data state. For the the compress recovery, a missing foo.add file results in foo.gz being restored to the previous compressed-only data state. - Append recovery: - Pick up append at + step above - Compress recovery: - Pick up compress at * step above - Replace recovery: - Pick up compress at @ step above - Log the repair with a date stamp in foo.repairs */ #include <sys/types.h> #include <stdio.h> /* rename, fopen, fprintf, fclose */ #include <stdlib.h> /* malloc, free */ #include <string.h> /* strlen, strrchr, strcpy, strncpy, strcmp */ #include <fcntl.h> /* open */ #include <unistd.h> /* lseek, read, write, close, unlink, sleep, */ /* ftruncate, fsync */ #include <errno.h> /* errno */ #include <time.h> /* time, ctime */ #include <sys/stat.h> /* stat */ #include <sys/time.h> /* utimes */ #include "zlib.h" /* crc32 */ #include "gzlog.h" /* header for external access */ #define local static typedef unsigned int uint; typedef unsigned long ulong; /* Macro for debugging to deterministically force recovery operations */ #ifdef GZLOG_DEBUG #include <setjmp.h> /* longjmp */ jmp_buf gzlog_jump; /* where to go back to */ int gzlog_bail = 0; /* which point to bail at (1..8) */ int gzlog_count = -1; /* number of times through to wait */ # define BAIL(n) do { if (n == gzlog_bail && gzlog_count-- == 0) \ longjmp(gzlog_jump, gzlog_bail); } while (0) #else # define BAIL(n) #endif /* how old the lock file can be in seconds before considering it stale */ #define PATIENCE 300 /* maximum stored block size in Kbytes -- must be in 1..63 */ #define MAX_STORE 16 /* number of stored Kbytes to trigger compression (must be >= 32 to allow dictionary construction, and <= 204 * MAX_STORE, in order for >> 10 to discard the stored block headers contribution of five bytes each) */ #define TRIGGER 1024 /* size of a deflate dictionary (this cannot be changed) */ #define DICT 32768U /* values for the operation (2 bits) */ #define NO_OP 0 #define APPEND_OP 1 #define COMPRESS_OP 2 #define REPLACE_OP 3 /* macros to extract little-endian integers from an unsigned byte buffer */ #define PULL2(p) ((p)[0]+((uint)((p)[1])<<8)) #define PULL4(p) (PULL2(p)+((ulong)PULL2(p+2)<<16)) #define PULL8(p) (PULL4(p)+((off_t)PULL4(p+4)<<32)) /* macros to store integers into a byte buffer in little-endian order */ #define PUT2(p,a) do {(p)[0]=a;(p)[1]=(a)>>8;} while(0) #define PUT4(p,a) do {PUT2(p,a);PUT2(p+2,a>>16);} while(0) #define PUT8(p,a) do {PUT4(p,a);PUT4(p+4,a>>32);} while(0) /* internal structure for log information */ #define LOGID "\106\035\172" /* should be three non-zero characters */ struct log { char id[4]; /* contains LOGID to detect inadvertent overwrites */ int fd; /* file descriptor for .gz file, opened read/write */ char *path; /* allocated path, e.g. "/var/log/foo" or "foo" */ char *end; /* end of path, for appending suffices such as ".gz" */ off_t first; /* offset of first stored block first length byte */ int back; /* location of first block id in bits back from first */ uint stored; /* bytes currently in last stored block */ off_t last; /* offset of last stored block first length byte */ ulong ccrc; /* crc of compressed data */ ulong clen; /* length (modulo 2^32) of compressed data */ ulong tcrc; /* crc of total data */ ulong tlen; /* length (modulo 2^32) of total data */ time_t lock; /* last modify time of our lock file */ }; /* gzip header for gzlog */ local unsigned char log_gzhead[] = { 0x1f, 0x8b, /* magic gzip id */ 8, /* compression method is deflate */ 4, /* there is an extra field (no file name) */ 0, 0, 0, 0, /* no modification time provided */ 0, 0xff, /* no extra flags, no OS specified */ 39, 0, 'a', 'p', 35, 0 /* extra field with "ap" subfield */ /* 35 is EXTRA, 39 is EXTRA + 4 */ }; #define HEAD sizeof(log_gzhead) /* should be 16 */ /* initial gzip extra field content (52 == HEAD + EXTRA + 1) */ local unsigned char log_gzext[] = { 52, 0, 0, 0, 0, 0, 0, 0, /* offset of first stored block length */ 52, 0, 0, 0, 0, 0, 0, 0, /* offset of last stored block length */ 0, 0, 0, 0, 0, 0, 0, 0, /* compressed data crc and length */ 0, 0, 0, 0, 0, 0, 0, 0, /* total data crc and length */ 0, 0, /* final stored block data length */ 5 /* op is NO_OP, last bit 8 bits back */ }; #define EXTRA sizeof(log_gzext) /* should be 35 */ /* initial gzip data and trailer */ local unsigned char log_gzbody[] = { 1, 0, 0, 0xff, 0xff, /* empty stored block (last) */ 0, 0, 0, 0, /* crc */ 0, 0, 0, 0 /* uncompressed length */ }; #define BODY sizeof(log_gzbody) /* Exclusively create foo.lock in order to negotiate exclusive access to the foo.* files.

We hope this helps explain some of the intricacies of <em>zlib</em>. <p> Without further adieu, here is the program <a href="zpipe.c"><tt>zpipe.c</tt></a>: <pre><b> /* zpipe.c: example of proper use of zlib's inflate() and deflate() Not copyrighted -- provided to the public domain Version 1.4 11 December 2005 Mark Adler */ /* Version history: 1.0 30 Oct 2004 First version 1.1 8 Nov 2004 Add void casting for unused return values Use switch statement for inflate() return values 1.2 9 Nov 2004 Add assertions to document zlib guarantees 1.3 6 Apr 2005 Remove incorrect assertion in inf() 1.4 11 Dec 2005 Add hack to avoid MSDOS end-of-line conversions Avoid some compiler warnings for input and output buffers */ </b></pre><!-- --> We now include the header files for the required definitions. From <tt>stdio.h</tt> we use <tt>fopen()</tt>, <tt>fread()</tt>, <tt>fwrite()</tt>, <tt>feof()</tt>, <tt>ferror()</tt>, and <tt>fclose()</tt> for file i/o, and <tt>fputs()</tt> for error messages. From <tt>string.h</tt> we use <tt>strcmp()</tt> for command line argument processing. From <tt>assert.h</tt> we use the <tt>assert()</tt> macro. From <tt>zlib.h</tt> we use the basic compression functions <tt>deflateInit()</tt>, <tt>deflate()</tt>, and <tt>deflateEnd()</tt>, and the basic decompression functions <tt>inflateInit()</tt>, <tt>inflate()</tt>, and <tt>inflateEnd()</tt>. <pre><b> #include <stdio.h> #include <string.h> #include <assert.h> #include "zlib.h" </b></pre><!-- --> This is an ugly hack required to avoid corruption of the input and output data on Windows/MS-DOS systems. Without this, those systems would assume that the input and output files are text, and try to convert the end-of-line characters from one standard to another. That would corrupt binary data, and in particular would render the compressed data unusable. This sets the input and output to binary which suppresses the end-of-line conversions. <tt>SET_BINARY_MODE()</tt> will be used later on <tt>stdin</tt> and <tt>stdout</tt>, at the beginning of <tt>main()</tt>. <pre><b> #if defined(MSDOS) || defined(OS2) || defined(WIN32) || defined(__CYGWIN__) # include <fcntl.h> # include <io.h> # define SET_BINARY_MODE(file) setmode(fileno(file), O_BINARY) #else # define SET_BINARY_MODE(file) #endif </b></pre><!-- --> <tt>CHUNK</tt> is simply the buffer size for feeding data to and pulling data from the <em>zlib</em> routines. Larger buffer sizes would be more efficient, especially for <tt>inflate()</tt>. If the memory is available, buffers sizes on the order of 128K or 256K bytes should be used. <pre><b> #define CHUNK 16384 </b></pre><!-- --> The <tt>def()</tt> routine compresses data from an input file to an output file. The output data will be in the <em>zlib</em> format, which is different from the <em>gzip</em> or <em>zip</em> formats. The <em>zlib</em> format has a very small header of only two bytes to identify it as a <em>zlib</em> stream and to provide decoding information, and a four-byte trailer with a fast check value to verify the integrity of the uncompressed data after decoding. <pre><b> /* Compress from file source to file dest until EOF on source. def() returns Z_OK on success, Z_MEM_ERROR if memory could not be allocated for processing, Z_STREAM_ERROR if an invalid compression level is supplied, Z_VERSION_ERROR if the version of zlib.h and the version of the library linked do not match, or Z_ERRNO if there is an error reading or writing the files. */ int def(FILE *source, FILE *dest, int level) { </b></pre> Here are the local variables for <tt>def()</tt>. <tt>ret</tt> will be used for <em>zlib</em> return codes. <tt>flush</tt> will keep track of the current flushing state for <tt>deflate()</tt>, which is either no flushing, or flush to completion after the end of the input file is reached. <tt>have</tt> is the amount of data returned from <tt>deflate()</tt>. The <tt>strm</tt> structure is used to pass information to and from the <em>zlib</em> routines, and to maintain the <tt>deflate()</tt> state. <tt>in</tt> and <tt>out</tt> are the input and output buffers for <tt>deflate()</tt>. <pre><b> int ret, flush; unsigned have; z_stream strm; unsigned char in[CHUNK]; unsigned char out[CHUNK]; </b></pre><!-- --> The first thing we do is to initialize the <em>zlib</em> state for compression using <tt>deflateInit()</tt>. This must be done before the first use of <tt>deflate()</tt>. The <tt>zalloc</tt>, <tt>zfree</tt>, and <tt>opaque</tt> fields in the <tt>strm</tt> structure must be initialized before calling <tt>deflateInit()</tt>. Here they are set to the <em>zlib</em> constant <tt>Z_NULL</tt> to request that <em>zlib</em> use the default memory allocation routines. An application may also choose to provide custom memory allocation routines here. <tt>deflateInit()</tt> will allocate on the order of 256K bytes for the internal state. (See <a href="zlib_tech.html"><em>zlib Technical Details</em></a>.) <p> <tt>deflateInit()</tt> is called with a pointer to the structure to be initialized and the compression level, which is an integer in the range of -1 to 9. Lower compression levels result in faster execution, but less compression. Higher levels result in greater compression, but slower execution. The <em>zlib</em> constant Z_DEFAULT_COMPRESSION, equal to -1, provides a good compromise between compression and speed and is equivalent to level 6. Level 0 actually does no compression at all, and in fact expands the data slightly to produce the <em>zlib</em> format (it is not a byte-for-byte copy of the input). More advanced applications of <em>zlib</em> may use <tt>deflateInit2()</tt> here instead. Such an application may want to reduce how much memory will be used, at some price in compression. Or it may need to request a <em>gzip</em> header and trailer instead of a <em>zlib</em> header and trailer, or raw encoding with no header or trailer at all. <p> We must check the return value of <tt>deflateInit()</tt> against the <em>zlib</em> constant <tt>Z_OK</tt> to make sure that it was able to allocate memory for the internal state, and that the provided arguments were valid. <tt>deflateInit()</tt> will also check that the version of <em>zlib</em> that the <tt>zlib.h</tt> file came from matches the version of <em>zlib</em> actually linked with the program. This is especially important for environments in which <em>zlib</em> is a shared library. <p> Note that an application can initialize multiple, independent <em>zlib</em> streams, which can operate in parallel. The state information maintained in the structure allows the <em>zlib</em> routines to be reentrant. <pre><b> /* allocate deflate state */ strm.zalloc = Z_NULL; strm.zfree = Z_NULL; strm.opaque = Z_NULL; ret = deflateInit(&strm, level); if (ret != Z_OK) return ret; </b></pre><!-- --> With the pleasantries out of the way, now we can get down to business. The outer <tt>do</tt>-loop reads all of the input file and exits at the bottom of the loop once end-of-file is reached. This loop contains the only call of <tt>deflate()</tt>. So we must make sure that all of the input data has been processed and that all of the output data has been generated and consumed before we fall out of the loop at the bottom. <pre><b> /* compress until end of file */ do { </b></pre> We start off by reading data from the input file. The number of bytes read is put directly into <tt>avail_in</tt>, and a pointer to those bytes is put into <tt>next_in</tt>. We also check to see if end-of-file on the input has been reached. If we are at the end of file, then <tt>flush</tt> is set to the <em>zlib</em> constant <tt>Z_FINISH</tt>, which is later passed to <tt>deflate()</tt> to indicate that this is the last chunk of input data to compress. We need to use <tt>feof()</tt> to check for end-of-file as opposed to seeing if fewer than <tt>CHUNK</tt> bytes have been read. The reason is that if the input file length is an exact multiple of <tt>CHUNK</tt>, we will miss the fact that we got to the end-of-file, and not know to tell <tt>deflate()</tt> to finish up the compressed stream. If we are not yet at the end of the input, then the <em>zlib</em> constant <tt>Z_NO_FLUSH</tt> will be passed to <tt>deflate</tt> to indicate that we are still in the middle of the uncompressed data. <p> If there is an error in reading from the input file, the process is aborted with <tt>deflateEnd()</tt> being called to free the allocated <em>zlib</em> state before returning the error. We wouldn't want a memory leak, now would we? <tt>deflateEnd()</tt> can be called at any time after the state has been initialized. Once that's done, <tt>deflateInit()</tt> (or <tt>deflateInit2()</tt>) would have to be called to start a new compression process. There is no point here in checking the <tt>deflateEnd()</tt> return code. The deallocation can't fail. <pre><b> strm.avail_in = fread(in, 1, CHUNK, source); if (ferror(source)) { (void)deflateEnd(&strm); return Z_ERRNO; } flush = feof(source) ? Z_FINISH : Z_NO_FLUSH; strm.next_in = in; </b></pre><!-- --> The inner <tt>do</tt>-loop passes our chunk of input data to <tt>deflate()</tt>, and then keeps calling <tt>deflate()</tt> until it is done producing output. Once there is no more new output, <tt>deflate()</tt> is guaranteed to have consumed all of the input, i.e., <tt>avail_in</tt> will be zero. <pre><b> /* run deflate() on input until output buffer not full, finish compression if all of source has been read in */ do { </b></pre> Output space is provided to <tt>deflate()</tt> by setting <tt>avail_out</tt> to the number of available output bytes and <tt>next_out</tt> to a pointer to that space. <pre><b> strm.avail_out = CHUNK; strm.next_out = out; </b></pre> Now we call the compression engine itself, <tt>deflate()</tt>. It takes as many of the <tt>avail_in</tt> bytes at <tt>next_in</tt> as it can process, and writes as many as <tt>avail_out</tt> bytes to <tt>next_out</tt>. Those counters and pointers are then updated past the input data consumed and the output data written. It is the amount of output space available that may limit how much input is consumed. Hence the inner loop to make sure that all of the input is consumed by providing more output space each time. Since <tt>avail_in</tt> and <tt>next_in</tt> are updated by <tt>deflate()</tt>, we don't have to mess with those between <tt>deflate()</tt> calls until it's all used up. <p> The parameters to <tt>deflate()</tt> are a pointer to the <tt>strm</tt> structure containing the input and output information and the internal compression engine state, and a parameter indicating whether and how to flush data to the output. Normally <tt>deflate</tt> will consume several K bytes of input data before producing any output (except for the header), in order to accumulate statistics on the data for optimum compression. It will then put out a burst of compressed data, and proceed to consume more input before the next burst. Eventually, <tt>deflate()</tt> must be told to terminate the stream, complete the compression with provided input data, and write out the trailer check value. <tt>deflate()</tt> will continue to compress normally as long as the flush parameter is <tt>Z_NO_FLUSH</tt>. Once the <tt>Z_FINISH</tt> parameter is provided, <tt>deflate()</tt> will begin to complete the compressed output stream. However depending on how much output space is provided, <tt>deflate()</tt> may have to be called several times until it has provided the complete compressed stream, even after it has consumed all of the input. The flush parameter must continue to be <tt>Z_FINISH</tt> for those subsequent calls. <p> There are other values of the flush parameter that are used in more advanced applications. You can force <tt>deflate()</tt> to produce a burst of output that encodes all of the input data provided so far, even if it wouldn't have otherwise, for example to control data latency on a link with compressed data. You can also ask that <tt>deflate()</tt> do that as well as erase any history up to that point so that what follows can be decompressed independently, for example for random access applications. Both requests will degrade compression by an amount depending on how often such requests are made. <p> <tt>deflate()</tt> has a return value that can indicate errors, yet we do not check it here. Why not? Well, it turns out that <tt>deflate()</tt> can do no wrong here. Let's go through <tt>deflate()</tt>'s return values and dispense with them one by one. The possible values are <tt>Z_OK</tt>, <tt>Z_STREAM_END</tt>, <tt>Z_STREAM_ERROR</tt>, or <tt>Z_BUF_ERROR</tt>. <tt>Z_OK</tt> is, well, ok. <tt>Z_STREAM_END</tt> is also ok and will be returned for the last call of <tt>deflate()</tt>. This is already guaranteed by calling <tt>deflate()</tt> with <tt>Z_FINISH</tt> until it has no more output. <tt>Z_STREAM_ERROR</tt> is only possible if the stream is not initialized properly, but we did initialize it properly. There is no harm in checking for <tt>Z_STREAM_ERROR</tt> here, for example to check for the possibility that some other part of the application inadvertently clobbered the memory containing the <em>zlib</em> state. <tt>Z_BUF_ERROR</tt> will be explained further below, but suffice it to say that this is simply an indication that <tt>deflate()</tt> could not consume more input or produce more output. <tt>deflate()</tt> can be called again with more output space or more available input, which it will be in this code. <pre><b> ret = deflate(&strm, flush); /* no bad return value */ assert(ret != Z_STREAM_ERROR); /* state not clobbered */ </b></pre> Now we compute how much output <tt>deflate()</tt> provided on the last call, which is the difference between how much space was provided before the call, and how much output space is still available after the call. Then that data, if any, is written to the output file. We can then reuse the output buffer for the next call of <tt>deflate()</tt>. Again if there is a file i/o error, we call <tt>deflateEnd()</tt> before returning to avoid a memory leak. <pre><b> have = CHUNK - strm.avail_out; if (fwrite(out, 1, have, dest) != have || ferror(dest)) { (void)deflateEnd(&strm); return Z_ERRNO; } </b></pre> The inner <tt>do</tt>-loop is repeated until the last <tt>deflate()</tt> call fails to fill the provided output buffer. Then we know that <tt>deflate()</tt> has done as much as it can with the provided input, and that all of that input has been consumed. We can then fall out of this loop and reuse the input buffer. <p> The way we tell that <tt>deflate()</tt> has no more output is by seeing that it did not fill the output buffer, leaving <tt>avail_out</tt> greater than zero. However suppose that <tt>deflate()</tt> has no more output, but just so happened to exactly fill the output buffer! <tt>avail_out</tt> is zero, and we can't tell that <tt>deflate()</tt> has done all it can. As far as we know, <tt>deflate()</tt> has more output for us. So we call it again. But now <tt>deflate()</tt> produces no output at all, and <tt>avail_out</tt> remains unchanged as <tt>CHUNK</tt>. That <tt>deflate()</tt> call wasn't able to do anything, either consume input or produce output, and so it returns <tt>Z_BUF_ERROR</tt>. (See, I told you I'd cover this later.) However this is not a problem at all. Now we finally have the desired indication that <tt>deflate()</tt> is really done, and so we drop out of the inner loop to provide more input to <tt>deflate()</tt>. <p> With <tt>flush</tt> set to <tt>Z_FINISH</tt>, this final set of <tt>deflate()</tt> calls will complete the output stream. Once that is done, subsequent calls of <tt>deflate()</tt> would return <tt>Z_STREAM_ERROR</tt> if the flush parameter is not <tt>Z_FINISH</tt>, and do no more processing until the state is reinitialized. <p> Some applications of <em>zlib</em> have two loops that call <tt>deflate()</tt> instead of the single inner loop we have here. The first loop would call without flushing and feed all of the data to <tt>deflate()</tt>. The second loop would call <tt>deflate()</tt> with no more data and the <tt>Z_FINISH</tt> parameter to complete the process. As you can see from this example, that can be avoided by simply keeping track of the current flush state. <pre><b> } while (strm.avail_out == 0); assert(strm.avail_in == 0); /* all input will be used */ </b></pre><!-- --> Now we check to see if we have already processed all of the input file. That information was saved in the <tt>flush</tt> variable, so we see if that was set to <tt>Z_FINISH</tt>. If so, then we're done and we fall out of the outer loop. We're guaranteed to get <tt>Z_STREAM_END</tt> from the last <tt>deflate()</tt> call, since we ran it until the last chunk of input was consumed and all of the output was generated. <pre><b> /* done when last data in file processed */ } while (flush != Z_FINISH); assert(ret == Z_STREAM_END); /* stream will be complete */ </b></pre><!-- --> The process is complete, but we still need to deallocate the state to avoid a memory leak (or rather more like a memory hemorrhage if you didn't do this). Then finally we can return with a happy return value. <pre><b> /* clean up and return */ (void)deflateEnd(&strm); return Z_OK; } </b></pre><!-- --> Now we do the same thing for decompression in the <tt>inf()</tt> routine. <tt>inf()</tt> decompresses what is hopefully a valid <em>zlib</em> stream from the input file and writes the uncompressed data to the output file. Much of the discussion above for <tt>def()</tt> applies to <tt>inf()</tt> as well, so the discussion here will focus on the differences between the two. <pre><b> /* Decompress from file source to file dest until stream ends or EOF. inf() returns Z_OK on success, Z_MEM_ERROR if memory could not be allocated for processing, Z_DATA_ERROR if the deflate data is invalid or incomplete, Z_VERSION_ERROR if the version of zlib.h and the version of the library linked do not match, or Z_ERRNO if there is an error reading or writing the files. */ int inf(FILE *source, FILE *dest) { </b></pre> The local variables have the same functionality as they do for <tt>def()</tt>. The only difference is that there is no <tt>flush</tt> variable, since <tt>inflate()</tt> can tell from the <em>zlib</em> stream itself when the stream is complete. <pre><b> int ret; unsigned have; z_stream strm; unsigned char in[CHUNK]; unsigned char out[CHUNK]; </b></pre><!-- --> The initialization of the state is the same, except that there is no compression level, of course, and two more elements of the structure are initialized. <tt>avail_in</tt> and <tt>next_in</tt> must be initialized before calling <tt>inflateInit()</tt>. This is because the application has the option to provide the start of the zlib stream in order for <tt>inflateInit()</tt> to have access to information about the compression method to aid in memory allocation. In the current implementation of <em>zlib</em> (up through versions 1.2.x), the method-dependent memory allocations are deferred to the first call of <tt>inflate()</tt> anyway. However those fields must be initialized since later versions of <em>zlib</em> that provide more compression methods may take advantage of this interface. In any case, no decompression is performed by <tt>inflateInit()</tt>, so the <tt>avail_out</tt> and <tt>next_out</tt> fields do not need to be initialized before calling. <p> Here <tt>avail_in</tt> is set to zero and <tt>next_in</tt> is set to <tt>Z_NULL</tt> to indicate that no input data is being provided. <pre><b> /* allocate inflate state */ strm.zalloc = Z_NULL; strm.zfree = Z_NULL; strm.opaque = Z_NULL; strm.avail_in = 0; strm.next_in = Z_NULL; ret = inflateInit(&strm); if (ret != Z_OK) return ret; </b></pre><!-- --> The outer <tt>do</tt>-loop decompresses input until <tt>inflate()</tt> indicates that it has reached the end of the compressed data and has produced all of the uncompressed output. This is in contrast to <tt>def()</tt> which processes all of the input file. If end-of-file is reached before the compressed data self-terminates, then the compressed data is incomplete and an error is returned. <pre><b> /* decompress until deflate stream ends or end of file */ do { </b></pre> We read input data and set the <tt>strm</tt> structure accordingly. If we've reached the end of the input file, then we leave the outer loop and report an error, since the compressed data is incomplete. Note that we may read more data than is eventually consumed by <tt>inflate()</tt>, if the input file continues past the <em>zlib</em> stream. For applications where <em>zlib</em> streams are embedded in other data, this routine would need to be modified to return the unused data, or at least indicate how much of the input data was not used, so the application would know where to pick up after the <em>zlib</em> stream. <pre><b> strm.avail_in = fread(in, 1, CHUNK, source); if (ferror(source)) { (void)inflateEnd(&strm); return Z_ERRNO; } if (strm.avail_in == 0) break; strm.next_in = in; </b></pre><!-- --> The inner <tt>do</tt>-loop has the same function it did in <tt>def()</tt>, which is to keep calling <tt>inflate()</tt> until has generated all of the output it can with the provided input. <pre><b> /* run inflate() on input until output buffer not full */ do { </b></pre> Just like in <tt>def()</tt>, the same output space is provided for each call of <tt>inflate()</tt>. <pre><b> strm.avail_out = CHUNK; strm.next_out = out; </b></pre> Now we run the decompression engine itself. There is no need to adjust the flush parameter, since the <em>zlib</em> format is self-terminating. The main difference here is that there are return values that we need to pay attention to. <tt>Z_DATA_ERROR</tt> indicates that <tt>inflate()</tt> detected an error in the <em>zlib</em> compressed data format, which means that either the data is not a <em>zlib</em> stream to begin with, or that the data was corrupted somewhere along the way since it was compressed. The other error to be processed is <tt>Z_MEM_ERROR</tt>, which can occur since memory allocation is deferred until <tt>inflate()</tt> needs it, unlike <tt>deflate()</tt>, whose memory is allocated at the start by <tt>deflateInit()</tt>. <p> Advanced applications may use <tt>deflateSetDictionary()</tt> to prime <tt>deflate()</tt> with a set of likely data to improve the first 32K or so of compression. This is noted in the <em>zlib</em> header, so <tt>inflate()</tt> requests that that dictionary be provided before it can start to decompress. Without the dictionary, correct decompression is not possible. For this routine, we have no idea what the dictionary is, so the <tt>Z_NEED_DICT</tt> indication is converted to a <tt>Z_DATA_ERROR</tt>. <p> <tt>inflate()</tt> can also return <tt>Z_STREAM_ERROR</tt>, which should not be possible here, but could be checked for as noted above for <tt>def()</tt>. <tt>Z_BUF_ERROR</tt> does not need to be checked for here, for the same reasons noted for <tt>def()</tt>. <tt>Z_STREAM_END</tt> will be checked for later. <pre><b> ret = inflate(&strm, Z_NO_FLUSH); assert(ret != Z_STREAM_ERROR); /* state not clobbered */ switch (ret) { case Z_NEED_DICT: ret = Z_DATA_ERROR; /* and fall through */ case Z_DATA_ERROR: case Z_MEM_ERROR: (void)inflateEnd(&strm); return ret; } </b></pre> The output of <tt>inflate()</tt> is handled identically to that of <tt>deflate()</tt>. <pre><b> have = CHUNK - strm.avail_out; if (fwrite(out, 1, have, dest) != have || ferror(dest)) { (void)inflateEnd(&strm); return Z_ERRNO; } </b></pre> The inner <tt>do</tt>-loop ends when <tt>inflate()</tt> has no more output as indicated by not filling the output buffer, just as for <tt>deflate()</tt>. In this case, we cannot assert that <tt>strm.avail_in</tt> will be zero, since the deflate stream may end before the file does. <pre><b> } while (strm.avail_out == 0); </b></pre><!-- --> The outer <tt>do</tt>-loop ends when <tt>inflate()</tt> reports that it has reached the end of the input <em>zlib</em> stream, has completed the decompression and integrity check, and has provided all of the output. This is indicated by the <tt>inflate()</tt> return value <tt>Z_STREAM_END</tt>. The inner loop is guaranteed to leave <tt>ret</tt> equal to <tt>Z_STREAM_END</tt> if the last chunk of the input file read contained the end of the <em>zlib</em> stream. So if the return value is not <tt>Z_STREAM_END</tt>, the loop continues to read more input. <pre><b> /* done when inflate() says it's done */ } while (ret != Z_STREAM_END); </b></pre><!-- --> At this point, decompression successfully completed, or we broke out of the loop due to no more data being available from the input file. If the last <tt>inflate()</tt> return value is not <tt>Z_STREAM_END</tt>, then the <em>zlib</em> stream was incomplete and a data error is returned. Otherwise, we return with a happy return value. Of course, <tt>inflateEnd()</tt> is called first to avoid a memory leak. <pre><b> /* clean up and return */ (void)inflateEnd(&strm); return ret == Z_STREAM_END ? Z_OK : Z_DATA_ERROR; } </b></pre><!-- --> That ends the routines that directly use <em>zlib</em>. The following routines make this a command-line program by running data through the above routines from <tt>stdin</tt> to <tt>stdout</tt>, and handling any errors reported by <tt>def()</tt> or <tt>inf()</tt>. <p> <tt>zerr()</tt> is used to interpret the possible error codes from <tt>def()</tt> and <tt>inf()</tt>, as detailed in their comments above, and print out an error message. Note that these are only a subset of the possible return values from <tt>deflate()</tt> and <tt>inflate()</tt>. <pre><b> /* report a zlib or i/o error */ void zerr(int ret) { fputs("zpipe: ", stderr); switch (ret) { case Z_ERRNO: if (ferror(stdin)) fputs("error reading stdin\n", stderr); if (ferror(stdout)) fputs("error writing stdout\n", stderr); break; case Z_STREAM_ERROR: fputs("invalid compression level\n", stderr); break; case Z_DATA_ERROR: fputs("invalid or incomplete deflate data\n", stderr); break; case Z_MEM_ERROR: fputs("out of memory\n", stderr); break; case Z_VERSION_ERROR: fputs("zlib version mismatch!\n", stderr); } } </b></pre><!-- --> Here is the <tt>main()</tt> routine used to test <tt>def()</tt> and <tt>inf()</tt>.

A file containing a zlib or gzip stream is provided on the command line. The compressed stream is decoded in its entirety, and an index built with access points about every SPAN bytes in the uncompressed output. The compressed file is left open, and can then be read randomly, having to decompress on the average SPAN/2 uncompressed bytes before getting to the desired block of data. An access point can be created at the start of any deflate block, by saving the starting file offset and bit of that block, and the 32K bytes of uncompressed data that precede that block. Also the uncompressed offset of that block is saved to provide a referece for locating a desired starting point in the uncompressed stream. build_index() works by decompressing the input zlib or gzip stream a block at a time, and at the end of each block deciding if enough uncompressed data has gone by to justify the creation of a new access point. If so, that point is saved in a data structure that grows as needed to accommodate the points. To use the index, an offset in the uncompressed data is provided, for which the latest access point at or preceding that offset is located in the index. The input file is positioned to the specified location in the index, and if necessary the first few bits of the compressed data is read from the file. inflate is initialized with those bits and the 32K of uncompressed data, and the decompression then proceeds until the desired offset in the file is reached. Then the decompression continues to read the desired uncompressed data from the file. Another approach would be to generate the index on demand. In that case, requests for random access reads from the compressed data would try to use the index, but if a read far enough past the end of the index is required, then further index entries would be generated and added. There is some fair bit of overhead to starting inflation for the random access, mainly copying the 32K byte dictionary. So if small pieces of the file are being accessed, it would make sense to implement a cache to hold some lookahead and avoid many calls to extract() for small lengths. Another way to build an index would be to use inflateCopy(). That would not be constrained to have access points at block boundaries, but requires more memory per access point, and also cannot be saved to file due to the use of pointers in the state. The approach here allows for storage of the index in a file. */ #include <stdio.h> #include <stdlib.h> #include <string.h> #include "zlib.h" #define local static #define SPAN 1048576L /* desired distance between access points */ #define WINSIZE 32768U /* sliding window size */ #define CHUNK 16384 /* file input buffer size */ /* access point entry */ struct point { off_t out; /* corresponding offset in uncompressed data */ off_t in; /* offset in input file of first full byte */ int bits; /* number of bits (1-7) from byte at in - 1, or 0 */ unsigned char window[WINSIZE]; /* preceding 32K of uncompressed data */ }; /* access point list */ struct access { int have; /* number of list entries filled in */ int size; /* number of list entries allocated */ struct point *list; /* allocated list */ }; /* Deallocate an index built by build_index() */ local void free_index(struct access *index) { if (index != NULL) { free(index->list); free(index); } } /* Add an entry to the access point list.

1.2.beta0 24 Nov 2002 * - First version -- complete rewrite of inflate to simplify code, avoid * creation of window when not needed, minimize use of window when it is * needed, make inffast.c even faster, implement gzip decoding, and to * improve code readability and style over the previous zlib inflate code * * 1.2.beta1 25 Nov 2002 * - Use pointers for available input and output checking in inffast.c * - Remove input and output counters in inffast.c * - Change inffast.c entry and loop from avail_in >= 7 to >= 6 * - Remove unnecessary second byte pull from length extra in inffast.c * - Unroll direct copy to three copies per loop in inffast.c * * 1.2.beta2 4 Dec 2002 * - Change external routine names to reduce potential conflicts * - Correct filename to inffixed.h for fixed tables in inflate.c * - Make hbuf[] unsigned char to match parameter type in inflate.c * - Change strm->next_out[-state->offset] to *(strm->next_out - state->offset) * to avoid negation problem on Alphas (64 bit) in inflate.c * * 1.2.beta3 22 Dec 2002 * - Add comments on state->bits assertion in inffast.c * - Add comments on op field in inftrees.h * - Fix bug in reuse of allocated window after inflateReset() * - Remove bit fields--back to byte structure for speed * - Remove distance extra == 0 check in inflate_fast()--only helps for lengths * - Change post-increments to pre-increments in inflate_fast(), PPC biased? * - Add compile time option, POSTINC, to use post-increments instead (Intel?) * - Make MATCH copy in inflate() much faster for when inflate_fast() not used * - Use local copies of stream next and avail values, as well as local bit * buffer and bit count in inflate()--for speed when inflate_fast() not used * * 1.2.beta4 1 Jan 2003 * - Split ptr - 257 statements in inflate_table() to avoid compiler warnings * - Move a comment on output buffer sizes from inffast.c to inflate.c * - Add comments in inffast.c to introduce the inflate_fast() routine * - Rearrange window copies in inflate_fast() for speed and simplification * - Unroll last copy for window match in inflate_fast() * - Use local copies of window variables in inflate_fast() for speed * - Pull out common wnext == 0 case for speed in inflate_fast() * - Make op and len in inflate_fast() unsigned for consistency * - Add FAR to lcode and dcode declarations in inflate_fast() * - Simplified bad distance check in inflate_fast() * - Added inflateBackInit(), inflateBack(), and inflateBackEnd() in new * source file infback.c to provide a call-back interface to inflate for * programs like gzip and unzip -- uses window as output buffer to avoid * window copying * * 1.2.beta5 1 Jan 2003 * - Improved inflateBack() interface to allow the caller to provide initial * input in strm. * - Fixed stored blocks bug in inflateBack() * * 1.2.beta6 4 Jan 2003 * - Added comments in inffast.c on effectiveness of POSTINC * - Typecasting all around to reduce compiler warnings * - Changed loops from while (1) or do {} while (1) to for (;;), again to * make compilers happy * - Changed type of window in inflateBackInit() to unsigned char * * * 1.2.beta7 27 Jan 2003 * - Changed many types to unsigned or unsigned short to avoid warnings * - Added inflateCopy() function * * 1.2.0 9 Mar 2003 * - Changed inflateBack() interface to provide separate opaque descriptors * for the in() and out() functions * - Changed inflateBack() argument and in_func typedef to swap the length * and buffer address return values for the input function * - Check next_in and next_out for Z_NULL on entry to inflate() * * The history for versions after 1.2.0 are in ChangeLog in zlib distribution. */ #include "zutil.h" #include "inftrees.h" #include "inflate.h" #include "inffast.h" #ifdef MAKEFIXED #

The state machine is structured roughly as follows: for (;;) switch (state) { ... case STATEn: if (not enough input data or output space to make progress) return; ... make progress ... state = STATEm; break; ... } so when inflate() is called again, the same case is attempted again, and if the appropriate resources are provided, the machine proceeds to the next state. The NEEDBITS() macro is usually the way the state evaluates whether it can proceed or should return. NEEDBITS() does the return if the requested bits are not available. The typical use of the BITS macros is: NEEDBITS(n); ... do something with BITS(n) ... DROPBITS(n); where NEEDBITS(n) either returns from inflate() if there isn't enough input left to load n bits into the accumulator, or it continues. BITS(n) gives the low n bits in the accumulator. When done, DROPBITS(n) drops the low n bits off the accumulator. INITBITS() clears the accumulator and sets the number of available bits to zero. BYTEBITS() discards just enough bits to put the accumulator on a byte boundary. After BYTEBITS() and a NEEDBITS(8), then BITS(8) would return the next byte in the stream. NEEDBITS(n) uses PULLBYTE() to get an available byte of input, or to return if there is no input available. The decoding of variable length codes uses PULLBYTE() directly in order to pull just enough bytes to decode the next code, and no more. Some states loop until they get enough input, making sure that enough state information is maintained to continue the loop where it left off if NEEDBITS() returns in the loop. For example, want, need, and keep would all have to actually be part of the saved state in case NEEDBITS() returns: case STATEw: while (want < need) { NEEDBITS(n); keep[want++] = BITS(n); DROPBITS(n); } state = STATEx; case STATEx: As shown above, if the next state is also the next case, then the break is omitted. A state may also return if there is not enough output space available to complete that state. Those states are copying stored data, writing a literal byte, and copying a matching string. When returning, a "goto inf_leave" is used to update the total counters, update the check value, and determine whether any progress has been made during that inflate() call in order to return the proper return code. Progress is defined as a change in either strm->avail_in or strm->avail_out. When there is a window, goto inf_leave will update the window with the last output written. If a goto inf_leave occurs in the middle of decompression and there is no window currently, goto inf_leave will create one and copy output to the window for the next call of inflate(). In this implementation, the flush parameter of inflate() only affects the return code (per zlib.h). inflate() always writes as much as possible to strm->next_out, given the space available and the provided input--the effect documented in zlib.h of Z_SYNC_FLUSH. Furthermore, inflate() always defers the allocation of and copying into a sliding window until necessary, which provides the effect documented in zlib.h for Z_FINISH when the entire input stream available. So the only thing the flush parameter actually does is: when flush is set to Z_FINISH, inflate() cannot return Z_OK. Instead it will return Z_BUF_ERROR if it has not reached the end of the stream. */ int ZEXPORT inflate(strm, flush) z_streamp strm; int flush; { struct inflate_state FAR *state; z_const unsigned char FAR *next; /* next input */ unsigned char FAR *put; /* next output */ unsigned have, left; /* available input and output */ unsigned long hold; /* bit buffer */ unsigned bits; /* bits in bit buffer */ unsigned in, out; /* save starting available input and output */ unsigned copy; /* number of stored or match bytes to copy */ unsigned char FAR *from; /* where to copy match bytes from */ code here; /* current decoding table entry */ code last; /* parent table entry */ unsigned len; /* length to copy for repeats, bits to drop */ int ret; /* return code */ #ifdef GUNZIP unsigned char hbuf[4]; /* buffer for gzip header crc calculation */ #endif static const unsigned short order[19] = /* permutation of code lengths */ {16, 17, 18, 0, 8, 7, 9, 6, 10, 5, 11, 4, 12, 3, 13, 2, 14, 1, 15}; if (inflateStateCheck(strm) || strm->next_out == Z_NULL || (strm->next_in == Z_NULL && strm->avail_in != 0)) return Z_STREAM_ERROR; state = (struct inflate_state FAR *)strm->state; if (state->mode == TYPE) state->mode = TYPEDO; /* skip check */ LOAD(); in = have; out = left; ret = Z_OK; for (;;) switch (state->mode) { case HEAD: if (state->wrap == 0) { state->mode = TYPEDO; break; } NEEDBITS(16); #ifdef GUNZIP if ((state->wrap & 2) && hold == 0x8b1f) { /* gzip header */ if (state->wbits == 0) state->wbits = 15; state->check = crc32(0L, Z_NULL, 0); CRC2(state->check, hold); INITBITS(); state->mode = FLAGS; break; } state->flags = 0; /* expect zlib header */ if (state->head != Z_NULL) state->head->done = -1; if (!(state->wrap & 1) || /* check if zlib header allowed */ #else if ( #endif ((BITS(8) << 8) + (hold >> 8)) % 31) { strm->msg = (char *)"incorrect header check"; state->mode = BAD; break; } if (BITS(4) != Z_DEFLATED) { strm->msg = (char *)"unknown compression method"; state->mode = BAD; break; } DROPBITS(4); len = BITS(4) + 8; if (state->wbits == 0) state->wbits = len; if (len > 15 || len > state->wbits) { strm->msg = (char *)"invalid window size"; state->mode = BAD; break; } state->dmax = 1U << len; Tracev((stderr, "inflate: zlib header ok\n")); strm->adler = state->check = adler32(0L, Z_NULL, 0); state->mode = hold & 0x200 ?

The code lengths are lens[0..codes-1]. Each length corresponds to the symbols 0..codes-1. The Huffman code is generated by first sorting the symbols by length from short to long, and retaining the symbol order for codes with equal lengths. Then the code starts with all zero bits for the first code of the shortest length, and the codes are integer increments for the same length, and zeros are appended as the length increases. For the deflate format, these bits are stored backwards from their more natural integer increment ordering, and so when the decoding tables are built in the large loop below, the integer codes are incremented backwards. This routine assumes, but does not check, that all of the entries in lens[] are in the range 0..MAXBITS. The caller must assure this. 1..MAXBITS is interpreted as that code length. zero means that that symbol does not occur in this code. The codes are sorted by computing a count of codes for each length, creating from that a table of starting indices for each length in the sorted table, and then entering the symbols in order in the sorted table. The sorted table is work[], with that space being provided by the caller. The length counts are used for other purposes as well, i.e. finding the minimum and maximum length codes, determining if there are any codes at all, checking for a valid set of lengths, and looking ahead at length counts to determine sub-table sizes when building the decoding tables. */ /* accumulate lengths for codes (assumes lens[] all in 0..MAXBITS) */ for (len = 0; len <= MAXBITS; len++) count[len] = 0; for (sym = 0; sym < codes; sym++) count[lens[sym]]++; /* bound code lengths, force root to be within code lengths */ root = *bits; for (max = MAXBITS; max >= 1; max--) if (count[max] != 0) break; if (root > max) root = max; if (max == 0) { /* no symbols to code at all */ here.op = (unsigned char)64; /* invalid code marker */ here.bits = (unsigned char)1; here.val = (unsigned short)0; *(*table)++ = here; /* make a table to force an error */ *(*table)++ = here; *bits = 1; return 0; /* no symbols, but wait for decoding to report error */ } for (min = 1; min < max; min++) if (count[min] != 0) break; if (root < min) root = min; /* check for an over-subscribed or incomplete set of lengths */ left = 1; for (len = 1; len <= MAXBITS; len++) { left <<= 1; left -= count[len]; if (left < 0) return -1; /* over-subscribed */ } if (left > 0 && (type == CODES || max != 1)) return -1; /* incomplete set */ /* generate offsets into symbol table for each length for sorting */ offs[1] = 0; for (len = 1; len < MAXBITS; len++) offs[len + 1] = offs[len] + count[len]; /* sort symbols by length, by symbol order within each length */ for (sym = 0; sym < codes; sym++) if (lens[sym] != 0) work[offs[lens[sym]]++] = (unsigned short)sym; /* Create and fill in decoding tables. In this loop, the table being filled is at next and has curr index bits. The code being used is huff with length len. That code is converted to an index by dropping drop bits off of the bottom. For codes where len is less than drop + curr, those top drop + curr - len bits are incremented through all values to fill the table with replicated entries. root is the number of index bits for the root table. When len exceeds root, sub-tables are created pointed to by the root entry with an index of the low root bits of huff. This is saved in low to check for when a new sub-table should be started. drop is zero when the root table is being filled, and drop is root when sub-tables are being filled. When a new sub-table is needed, it is necessary to look ahead in the code lengths to determine what size sub-table is needed. The length counts are used for this, and so count[] is decremented as codes are entered in the tables. used keeps track of how many table entries have been allocated from the provided *table space. It is checked for LENS and DIST tables against the constants ENOUGH_LENS and ENOUGH_DISTS to guard against changes in the initial root table size constants. See the comments in inftrees.h for more information. sym increments through all symbols, and the loop terminates when all codes of length max, i.e. all codes, have been processed.

Frequently Asked Question: Q: Each time I use the compress function I get the -5 error (not enough room in the output buffer). A: Make sure that the length of the compressed buffer is passed by reference ("as any"), not by value ("as long"). Also check that before the call of compress this length is equal to the total size of the compressed buffer and not zero.

(i.e.: /path/to/the/zlib/ifs/source/directory) If the installed IFS command suppors gzip format, this is straightforward, else you have to unpack first to some directory on a system supporting it, then move the whole directory to the IFS via the network (via SMB or FTP). 2) Edit the configuration parameters in the compilation script. EDTF STMF('/path/to/the/zlib/ifs/source/directory/os400/make.sh') Tune the parameters according to your needs if not matching the defaults. Save the file and exit after edition. 3) Enter qshell, then work in the zlib OS/400 specific directory. QSH cd /path/to/the/zlib/ifs/source/directory/os400 4) Compile and install sh make.sh The script will: - create the libraries, objects and IFS directories for the zlib environment, - compile all modules, - create a service program, - create a static and a dynamic binding directory, - install header files for C/C++ and for ILE/RPG, both for compilation in DB2 and IFS environments. That's all. Notes: For OS/400 ILE RPG programmers, a /copy member defining the ZLIB API prototypes for ILE RPG can be found in ZLIB/H(ZLIB.INC). In the ILE environment, the same definitions are available from file zlib.inc located in the same IFS include directory as the C/C++ header files. Please read comments in this member for more information. Remember that most foreign textual data are ASCII coded: this implementation does not handle conversion from/to ASCII, so text data code conversions must be done explicitely. Mainly for the reason above, always open zipped files in binary mode. |

If you have general questions about zlib, you should see the file "FAQ" found in the zlib distribution, or at the following location: http://www.gzip.org/zlib/zlib_faq.html 1. What is ZLIB1.DLL, and how can I get it? - ZLIB1.DLL is the official build of zlib as a DLL. (Please remark the character '1' in the name.) Pointers to a precompiled ZLIB1.DLL can be found in the zlib web site at: http://www.zlib.net/ Applications that link to ZLIB1.DLL can rely on the following specification: * The exported symbols are exclusively defined in the source files "zlib.h" and "zlib.def", found in an official zlib source distribution. * The symbols are exported by name, not by ordinal. * The exported names are undecorated. * The calling convention of functions is "C" (CDECL). * The ZLIB1.DLL binary is linked to MSVCRT.DLL. The archive in which ZLIB1.DLL is bundled contains compiled test programs that must run with a valid build of ZLIB1.DLL. It is recommended to download the prebuilt DLL from the zlib web site, instead of building it yourself, to avoid potential incompatibilities that could be introduced by your compiler and build settings. If you do build the DLL yourself, please make sure that it complies with all the above requirements, and it runs with the precompiled test programs, bundled with the original ZLIB1.DLL distribution. If, for any reason, you need to build an incompatible DLL, please use a different file name. 2. Why did you change the name of the DLL to ZLIB1.DLL? What happened to the old ZLIB.DLL? - The old ZLIB.DLL, built from zlib-1.1.4 or earlier, required compilation settings that were incompatible to those used by a static build. The DLL settings were supposed to be enabled by defining the macro ZLIB_DLL, before including "zlib.h". Incorrect handling of this macro was silently accepted at build time, resulting in two major problems: * ZLIB_DLL was missing from the old makefile. When building the DLL, not all people added it to the build options. In consequence, incompatible incarnations of ZLIB.DLL started to circulate around the net. * When switching from using the static library to using the DLL, applications had to define the ZLIB_DLL macro and to recompile all the sources that contained calls to zlib functions. Failure to do so resulted in creating binaries that were unable to run with the official ZLIB.DLL build. The only possible solution that we could foresee was to make a binary-incompatible change in the DLL interface, in order to remove the dependency on the ZLIB_DLL macro, and to release the new DLL under a different name. We chose the name ZLIB1.DLL, where '1' indicates the major zlib version number. We hope that we will not have to break the binary compatibility again, at least not as long as the zlib-1.x series will last. There is still a ZLIB_DLL macro, that can trigger a more efficient build and use of the DLL, but compatibility no longer dependents on it. 3. Can I build ZLIB.DLL from the new zlib sources, and replace an old ZLIB.DLL, that was built from zlib-1.1.4 or earlier? - In principle, you can do it by assigning calling convention keywords to the macros ZEXPORT and ZEXPORTVA. In practice, it depends on what you mean by "an old ZLIB.DLL", because the old DLL exists in several mutually-incompatible versions. You have to find out first what kind of calling convention is being used in your particular ZLIB.DLL build, and to use the same one in the new build. If you don't know what this is all about, you might be better off if you would just leave the old DLL intact. 4. Can I compile my application using the new zlib interface, and link it to an old ZLIB.DLL, that was built from zlib-1.1.4 or earlier? - The official answer is "no"; the real answer depends again on what kind of ZLIB.DLL you have. Even if you are lucky, this course of action is unreliable. If you rebuild your application and you intend to use a newer version of zlib (post- 1.1.4), it is strongly recommended to link it to the new ZLIB1.DLL. 5. Why are the zlib symbols exported by name, and not by ordinal? - Although exporting symbols by ordinal is a little faster, it is risky. Any single glitch in the maintenance or use of the DEF file that contains the ordinals can result in incompatible builds and frustrating crashes. Simply put, the benefits of exporting symbols by ordinal do not justify the risks. Technically, it should be possible to maintain ordinals in the DEF file, and still export the symbols by name. Ordinals exist in every DLL, and even if the dynamic linking performed at the DLL startup is searching for names, ordinals serve as hints, for a faster name lookup. However, if the DEF file contains ordinals, the Microsoft linker automatically builds an implib that will cause the executables linked to it to use those ordinals, and not the names. It is interesting to notice that the GNU linker for Win32 does not suffer from this problem. It is possible to avoid the DEF file if the exported symbols are accompanied by a "__declspec(dllexport)" attribute in the source files. You can do this in zlib by predefining the ZLIB_DLL macro. 6. I see that the ZLIB1.DLL functions use the "C" (CDECL) calling convention. Why not use the STDCALL convention? STDCALL is the standard convention in Win32, and I need it in my Visual Basic project! (For readability, we use CDECL to refer to the convention triggered by the "__cdecl" keyword, STDCALL to refer to the convention triggered by "__stdcall", and FASTCALL to refer to the convention triggered by "__fastcall".) - Most of the native Windows API functions (without varargs) use indeed the WINAPI convention (which translates to STDCALL in Win32), but the standard C functions use CDECL. If a user application is intrinsically tied to the Windows API (e.g. it calls native Windows API functions such as CreateFile()), sometimes it makes sense to decorate its own functions with WINAPI. But if ANSI C or POSIX portability is a goal (e.g. it calls standard C functions such as fopen()), it is not a sound decision to request the inclusion of <windows.h>, or to use non-ANSI constructs, for the sole purpose to make the user functions STDCALL-able. The functionality offered by zlib is not in the category of "Windows functionality", but is more like "C functionality". Technically, STDCALL is not bad; in fact, it is slightly faster than CDECL, and it works with variable-argument functions, just like CDECL. It is unfortunate that, in spite of using STDCALL in the Windows API, it is not the default convention used by the C compilers that run under Windows. The roots of the problem reside deep inside the unsafety of the K&R-style function prototypes, where the argument types are not specified; but that is another story for another day. The remaining fact is that CDECL is the default convention. Even if an explicit convention is hard-coded into the function prototypes inside C headers, problems may appear. The necessity to expose the convention in users' callbacks is one of these problems. The calling convention issues are also important when using zlib in other programming languages. Some of them, like Ada (GNAT) and Fortran (GNU G77), have C bindings implemented initially on Unix, and relying on the C calling convention. On the other hand, the pre- .NET versions of Microsoft Visual Basic require STDCALL, while Borland Delphi prefers, although it does not require, FASTCALL. In fairness to all possible uses of zlib outside the C programming language, we choose the default "C" convention. Anyone interested in different bindings or conventions is encouraged to maintain specialized projects. The "contrib/" directory from the zlib distribution already holds a couple of foreign bindings, such as Ada, C++, and Delphi. 7. I need a DLL for my Visual Basic project. What can I do? - Define the ZLIB_WINAPI macro before including "zlib.h", when building both the DLL and the user application (except that you don't need to define anything when using the DLL in Visual Basic). The ZLIB_WINAPI macro will switch on the WINAPI (STDCALL) convention. The name of this DLL must be different than the official ZLIB1.DLL. Gilles Vollant has contributed a build named ZLIBWAPI.DLL, with the ZLIB_WINAPI macro turned on, and with the minizip functionality built in. For more information, please read the notes inside "contrib/vstudio/readme.txt", found in the zlib distribution. 8. I need to use zlib in my Microsoft .NET project. What can I do? - Henrik Ravn has contributed a .NET wrapper around zlib. Look into contrib/dotzlib/, inside the zlib distribution. 9. If my application uses ZLIB1.DLL, should I link it to MSVCRT.DLL? Why? - It is not required, but it is recommended to link your application to MSVCRT.DLL, if it uses ZLIB1.DLL. The executables (.EXE, .DLL, etc.) that are involved in the same process and are using the C run-time library (i.e. they are calling standard C functions), must link to the same library. There are several libraries in the Win32 system: CRTDLL.DLL, MSVCRT.DLL, the static C libraries, etc. Since ZLIB1.DLL is linked to MSVCRT.DLL, the executables that depend on it should also be linked to MSVCRT.DLL. 10. Why are you saying that ZLIB1.DLL and my application should be linked to the same C run-time (CRT) library? I linked my application and my DLLs to different C libraries (e.g. my application to a static library, and my DLLs to MSVCRT.DLL), and everything works fine. - If a user library invokes only pure Win32 API (accessible via <windows.h> and the related headers), its DLL build will work in any context. But if this library invokes standard C API, things get more complicated. There is a single Win32 library in a Win32 system. Every function in this library resides in a single DLL module, that is safe to call from anywhere. On the other hand, there are multiple versions of the C library, and each of them has its own separate internal state. Standalone executables and user DLLs that call standard C functions must link to a C run-time (CRT) library, be it static or shared (DLL). Intermixing occurs when an executable (not necessarily standalone) and a DLL are linked to different CRTs, and both are running in the same process. Intermixing multiple CRTs is possible, as long as their internal states are kept intact. The Microsoft Knowledge Base articles KB94248 "HOWTO: Use the C Run-Time" and KB140584 "HOWTO: Link with the Correct C Run-Time (CRT) Library" mention the potential problems raised by intermixing. If intermixing works for you, it's because your application and DLLs are avoiding the corruption of each of the CRTs' internal states, maybe by careful design, or maybe by fortune. Also note that linking ZLIB1.DLL to non-Microsoft CRTs, such as those provided by Borland, raises similar problems. 11. Why are you linking ZLIB1.DLL to MSVCRT.DLL? - MSVCRT.DLL exists on every Windows 95 with a new service pack installed, or with Microsoft Internet Explorer 4 or later, and on all other Windows 4.x or later (Windows 98, Windows NT 4, or later). It is freely distributable; if not present in the system, it can be downloaded from Microsoft or from other software provider for free. The fact that MSVCRT.DLL does not exist on a virgin Windows 95 is not so problematic. Windows 95 is scarcely found nowadays, Microsoft ended its support a long time ago, and many recent applications from various vendors, including Microsoft, do not even run on it. Furthermore, no serious user should run Windows 95 without a proper update installed. 12. Why are you not linking ZLIB1.DLL to <<my favorite C run-time library>> ? - We considered and abandoned the following alternatives: * Linking ZLIB1.DLL to a static C library (LIBC.LIB, or LIBCMT.LIB) is not a good option. People are using the DLL mainly to save disk space. If you are linking your program to a static C library, you may as well consider linking zlib in statically, too. * Linking ZLIB1.DLL to CRTDLL.DLL looks appealing, because CRTDLL.DLL is present on every Win32 installation. Unfortunately, it has a series of problems: it does not work properly with Microsoft's C++ libraries, it does not provide support for 64-bit file offsets, (and so on...), and Microsoft discontinued its support a long time ago. * Linking ZLIB1.DLL to MSVCR70.DLL or MSVCR71.DLL, supplied with the Microsoft .NET platform, and Visual C++ 7.0/7.1, raises problems related to the status of ZLIB1.DLL as a system component. According to the Microsoft Knowledge Base article KB326922 "INFO: Redistribution of the Shared C Runtime Component in Visual C++ .NET", MSVCR70.DLL and MSVCR71.DLL are not supposed to function as system DLLs, because they may clash with MSVCRT.DLL. Instead, the application's installer is supposed to put these DLLs (if needed) in the application's private directory. If ZLIB1.DLL depends on a non-system runtime, it cannot function as a redistributable system component. * Linking ZLIB1.DLL to non-Microsoft runtimes, such as Borland's, or Cygwin's, raises problems related to the reliable presence of these runtimes on Win32 systems. It's easier to let the DLL build of zlib up to the people who distribute these runtimes, and who may proceed as explained in the answer to Question 14. 13. If ZLIB1.DLL cannot be linked to MSVCR70.DLL or MSVCR71.DLL, how can I build/use ZLIB1.DLL in Microsoft Visual C++ 7.0 (Visual Studio .NET) or newer? - Due to the problems explained in the Microsoft Knowledge Base article KB326922 (see the previous answer), the C runtime that comes with the VC7 environment is no longer considered a system component. That is, it should not be assumed that this runtime exists, or may be installed in a system directory. Since ZLIB1.DLL is supposed to be a system component, it may not depend on a non-system component. In order to link ZLIB1.DLL and your application to MSVCRT.DLL in VC7, you need the library of Visual C++ 6.0 or older. If you don't have this library at hand, it's probably best not to use ZLIB1.DLL. We are hoping that, in the future, Microsoft will provide a way to build applications linked to a proper system runtime, from the Visual C++ environment. Until then, you have a couple of alternatives, such as linking zlib in statically. If your application requires dynamic linking, you may proceed as explained in the answer to Question 14. 14. I need to link my own DLL build to a CRT different than MSVCRT.DLL. What can I do? - Feel free to rebuild the DLL from the zlib sources, and link it the way you want. You should, however, clearly state that your build is unofficial. You should give it a different file name, and/or install it in a private directory that can be accessed by your application only, and is not visible to the others (i.e. it's neither in the PATH, nor in the SYSTEM or SYSTEM32 directories). Otherwise, your build may clash with applications that link to the official build. For example, in Cygwin, zlib is linked to the Cygwin runtime CYGWIN1.DLL, and it is distributed under the name CYGZ.DLL. 15. May I include additional pieces of code that I find useful, link them in ZLIB1.DLL, and export them? - No. A legitimate build of ZLIB1.DLL must not include code that does not originate from the official zlib source code. But you can make your own private DLL build, under a different file name, as suggested in the previous answer. For example, zlib is a part of the VCL library, distributed with Borland Delphi and C++ Builder. The DLL build of VCL is a redistributable file, named VCLxx.DLL. 16. May I remove some functionality out of ZLIB1.DLL, by enabling macros like NO_GZCOMPRESS or NO_GZIP at compile time? - No. A legitimate build of ZLIB1.DLL must provide the complete zlib functionality, as implemented in the official zlib source code. But you can make your own private DLL build, under a different file name, as suggested in the previous answer. 17. I made my own ZLIB1.DLL build. Can I test it for compliance? - We prefer that you download the official DLL from the zlib web site. If you need something peculiar from this DLL, you can send your suggestion to the zlib mailing list. However, in case you do rebuild the DLL yourself, you can run it with the test programs found in the DLL distribution.

All the code is thread safe. The data format used by the zlib library is described by RFCs (Request for Comments) 1950 to 1952 in the files http://www.ietf.org/rfc/rfc1950.txt (zlib format), rfc1951.txt (deflate format) and rfc1952.txt (gzip format). All functions of the compression library are documented in the file zlib.h (volunteer to write man pages welcome, contact zlib@gzip.org). Two compiled examples are distributed in this package, example and minigzip. The example_d and minigzip_d flavors validate that the zlib1.dll file is working correctly. Questions about zlib should be sent to <zlib@gzip.org>. The zlib home page is http://zlib.net/ . Before reporting a problem, please check this site to verify that you have the latest version of zlib; otherwise get the latest version and check whether the problem still exists or not. PLEASE read DLL_FAQ.txt, and the the zlib FAQ http://zlib.net/zlib_faq.html before asking for help. Manifest: The package zlib-1.2.11-win32-x86.zip will contain the following files: README-WIN32.txt This document ChangeLog Changes since previous zlib packages DLL_FAQ.txt Frequently asked questions about zlib1.dll zlib.3.pdf Documentation of this library in Adobe Acrobat format example.exe A statically-bound example (using zlib.lib, not the dll) example.pdb Symbolic information for debugging example.exe example_d.exe A zlib1.dll bound example (using zdll.lib) example_d.pdb Symbolic information for debugging example_d.exe minigzip.exe A statically-bound test program (using zlib.lib, not the dll) minigzip.pdb Symbolic information for debugging minigzip.exe minigzip_d.exe A zlib1.dll bound test program (using zdll.lib) minigzip_d.pdb Symbolic information for debugging minigzip_d.exe zlib.h Install these files into the compilers' INCLUDE path to zconf.h compile programs which use zlib.lib or zdll.lib zdll.lib Install these files into the compilers' LIB path if linking zdll.exp a compiled program to the zlib1.dll binary zlib.lib Install these files into the compilers' LIB path to link zlib zlib.pdb into compiled programs, without zlib1.dll runtime dependency (zlib.pdb provides debugging info to the compile time linker) zlib1.dll Install this binary shared library into the system PATH, or the program's runtime directory (where the .exe resides) zlib1.pdb Install in the same directory as zlib1.dll, in order to debug an application crash using WinDbg or similar tools. All .pdb files above are entirely optional, but are very useful to a developer attempting to diagnose program misbehavior or a crash. Many additional important files for developers can be found in the zlib127.zip source package available from http://zlib.net/ - review that package's README file for details.

The code is thread safe, assuming that the standard library functions used are thread safe, such as memory allocation routines. It provides in-memory compression and decompression functions, including integrity checks of the uncompressed data. This version of the library supports only one compression method (deflation) but other algorithms may be added later with the same stream interface. .LP Compression can be done in a single step if the buffers are large enough or can be done by repeated calls of the compression function. In the latter case, the application must provide more input and/or consume the output (providing more output space) before each call. .LP The library also supports reading and writing files in .IR gzip (1) (.gz) format with an interface similar to that of stdio. .LP The library does not install any signal handler. The decoder checks the consistency of the compressed data, so the library should never crash even in the case of corrupted input. .LP All functions of the compression library are documented in the file .IR zlib.h . The distribution source includes examples of use of the library in the files .I test/example.c and .IR test/minigzip.c, as well as other examples in the .IR examples/ directory. .LP Changes to this version are documented in the file .I ChangeLog that accompanies the source. .LP .I zlib is built in to many languages and operating systems, including but not limited to Java, Python, .NET, PHP, Perl, Ruby, Swift, and Go. .LP An experimental package to read and write files in the .zip format, written on top of .I zlib by Gilles Vollant (info@winimage.com), is available at: .IP http://www.winimage.com/zLibDll/minizip.html and also in the .I contrib/minizip directory of the main .I zlib source distribution. .SH "SEE ALSO" The .I zlib web site can be found at: .IP http://zlib.net/ .LP The data format used by the .I zlib library is described by RFC (Request for Comments) 1950 to 1952 in the files: .IP http://tools.ietf.org/html/rfc1950 (for the zlib header and trailer format) .br http://tools.ietf.org/html/rfc1951 (for the deflate compressed data format) .br http://tools.ietf.org/html/rfc1952 (for the gzip header and trailer format) .LP Mark Nelson wrote an article about .I zlib for the Jan. 1997 issue of Dr. Dobb's Journal; a copy of the article is available at: .IP http://marknelson.us/1997/01/01/zlib-engine/ .SH "REPORTING PROBLEMS" Before reporting a problem, please check the .I zlib web site to verify that you have the latest version of .IR zlib ; otherwise, obtain the latest version and see if the problem still exists. Please read the .I zlib FAQ at: .IP http://zlib.net/zlib_faq.html .LP before asking for help. Send questions and/or comments to zlib@gzip.org, or (for the Windows DLL version) to Gilles Vollant (info@winimage.com). .SH AUTHORS AND LICENSE Version 1.2.11 .LP Copyright (C) 1995-2017 Jean-loup Gailly and Mark Adler .LP This software is provided 'as-is', without any express or implied warranty.

Jean-loup Gailly Mark Adler jloup@gzip.org madler@alumni.caltech.edu The data format used by the zlib library is described by RFCs (Request for Comments) 1950 to 1952 in the files http://tools.ietf.org/html/rfc1950 (zlib format), rfc1951 (deflate format) and rfc1952 (gzip format). */ #ifndef ZLIB_H #define ZLIB_H #include "zconf.h" #ifdef __cplusplus extern "C" { #endif #define ZLIB_VERSION "1.2.11" #define ZLIB_VERNUM 0x12b0 #define ZLIB_VER_MAJOR 1 #define ZLIB_VER_MINOR 2 #define ZLIB_VER_REVISION 11 #define ZLIB_VER_SUBREVISION 0 /* The 'zlib' compression library provides in-memory compression and decompression functions, including integrity checks of the uncompressed data. This version of the library supports only one compression method (deflation) but other algorithms will be added later and will have the same stream interface. Compression can be done in a single step if the buffers are large enough, or can be done by repeated calls of the compression function. In the latter case, the application must provide more input and/or consume the output (providing more output space) before each call. The compressed data format used by default by the in-memory functions is the zlib format, which is a zlib wrapper documented in RFC 1950, wrapped around a deflate stream, which is itself documented in RFC 1951. The library also supports reading and writing files in gzip (.gz) format with an interface similar to that of stdio using the functions that start with "gz". The gzip format is different from the zlib format. gzip is a gzip wrapper, documented in RFC 1952, wrapped around a deflate stream. This library can optionally read and write gzip and raw deflate streams in memory as well. The zlib format was designed to be compact and fast for use in memory and on communications channels. The gzip format was designed for single- file compression on file systems, has a larger header than zlib to maintain directory information, and uses a different, slower check method than zlib. The library does not install any signal handler. The decoder checks the consistency of the compressed data, so the library should never crash even in the case of corrupted input. */ typedef voidpf (*alloc_func) OF((voidpf opaque, uInt items, uInt size)); typedef void (*free_func) OF((voidpf opaque, voidpf address)); struct internal_state; typedef struct z_stream_s { z_const Bytef *next_in; /* next input byte */ uInt avail_in; /* number of bytes available at next_in */ uLong total_in; /* total number of input bytes read so far */ Bytef *next_out; /* next output byte will go here */ uInt avail_out; /* remaining free space at next_out */ uLong total_out; /* total number of bytes output so far */ z_const char *msg; /* last error message, NULL if no error */ struct internal_state FAR *state; /* not visible by applications */ alloc_func zalloc; /* used to allocate the internal state */ free_func zfree; /* used to free the internal state */ voidpf opaque; /* private data object passed to zalloc and zfree */ int data_type; /* best guess about the data type: binary or text for deflate, or the decoding state for inflate */ uLong adler; /* Adler-32 or CRC-32 value of the uncompressed data */ uLong reserved; /* reserved for future use */ } z_stream; typedef z_stream FAR *z_streamp; /* gzip header information passed to and from zlib routines.

It must update next_out and avail_out when avail_out has dropped to zero. The application must initialize zalloc, zfree and opaque before calling the init function. All other fields are set by the compression library and must not be updated by the application. The opaque value provided by the application will be passed as the first parameter for calls of zalloc and zfree. This can be useful for custom memory management. The compression library attaches no meaning to the opaque value. zalloc must return Z_NULL if there is not enough memory for the object. If zlib is used in a multi-threaded application, zalloc and zfree must be thread safe. In that case, zlib is thread-safe. When zalloc and zfree are Z_NULL on entry to the initialization function, they are set to internal routines that use the standard library functions malloc() and free(). On 16-bit systems, the functions zalloc and zfree must be able to allocate exactly 65536 bytes, but will not be required to allocate more than this if the symbol MAXSEG_64K is defined (see zconf.h). WARNING: On MSDOS, pointers returned by zalloc for objects of exactly 65536 bytes *must* have their offset normalized to zero. The default allocation function provided by this library ensures this (see zutil.c). To reduce memory requirements and avoid any allocation of 64K objects, at the expense of compression ratio, compile the library with -DMAX_WBITS=14 (see zconf.h). The fields total_in and total_out can be used for statistics or progress reports. After compression, total_in holds the total size of the uncompressed data and may be saved for use by the decompressor (particularly if the decompressor wants to decompress everything in a single step). */ /* constants */ #define Z_NO_FLUSH 0 #define Z_PARTIAL_FLUSH 1 #define Z_SYNC_FLUSH 2 #define Z_FULL_FLUSH 3 #define Z_FINISH 4 #define Z_BLOCK 5 #define Z_TREES 6 /* Allowed flush values; see deflate() and inflate() below for details */ #define Z_OK 0 #define Z_STREAM_END 1 #define Z_NEED_DICT 2 #define Z_ERRNO (-1) #define Z_STREAM_ERROR (-2) #define Z_DATA_ERROR (-3) #define Z_MEM_ERROR (-4) #define Z_BUF_ERROR (-5) #define Z_VERSION_ERROR (-6) /* Return codes for the compression/decompression functions.

If not all input can be processed (because there is not enough room in the output buffer), next_in and avail_in are updated and processing will resume at this point for the next call of deflate(). - Generate more output starting at next_out and update next_out and avail_out accordingly. This action is forced if the parameter flush is non zero. Forcing flush frequently degrades the compression ratio, so this parameter should be set only when necessary. Some output may be provided even if flush is zero. Before the call of deflate(), the application should ensure that at least one of the actions is possible, by providing more input and/or consuming more output, and updating avail_in or avail_out accordingly; avail_out should never be zero before the call. The application can consume the compressed output when it wants, for example when the output buffer is full (avail_out == 0), or after each call of deflate(). If deflate returns Z_OK and with zero avail_out, it must be called again after making room in the output buffer because there might be more output pending. See deflatePending(), which can be used if desired to determine whether or not there is more ouput in that case. Normally the parameter flush is set to Z_NO_FLUSH, which allows deflate to decide how much data to accumulate before producing output, in order to maximize compression. If the parameter flush is set to Z_SYNC_FLUSH, all pending output is flushed to the output buffer and the output is aligned on a byte boundary, so that the decompressor can get all input data available so far. (In particular avail_in is zero after the call if enough output space has been provided before the call.) Flushing may degrade compression for some compression algorithms and so it should be used only when necessary. This completes the current deflate block and follows it with an empty stored block that is three bits plus filler bits to the next byte, followed by four bytes (00 00 ff ff). If flush is set to Z_PARTIAL_FLUSH, all pending output is flushed to the output buffer, but the output is not aligned to a byte boundary. All of the input data so far will be available to the decompressor, as for Z_SYNC_FLUSH. This completes the current deflate block and follows it with an empty fixed codes block that is 10 bits long. This assures that enough bytes are output in order for the decompressor to finish the block before the empty fixed codes block. If flush is set to Z_BLOCK, a deflate block is completed and emitted, as for Z_SYNC_FLUSH, but the output is not aligned on a byte boundary, and up to seven bits of the current block are held to be written as the next byte after the next deflate block is completed. In this case, the decompressor may not be provided enough bits at this point in order to complete decompression of the data provided so far to the compressor. It may need to wait for the next block to be emitted. This is for advanced applications that need to control the emission of deflate blocks. If flush is set to Z_FULL_FLUSH, all output is flushed as with Z_SYNC_FLUSH, and the compression state is reset so that decompression can restart from this point if previous compressed data has been damaged or if random access is desired. Using Z_FULL_FLUSH too often can seriously degrade compression. If deflate returns with avail_out == 0, this function must be called again with the same value of the flush parameter and more output space (updated avail_out), until the flush is complete (deflate returns with non-zero avail_out). In the case of a Z_FULL_FLUSH or Z_SYNC_FLUSH, make sure that avail_out is greater than six to avoid repeated flush markers due to avail_out == 0 on return. If the parameter flush is set to Z_FINISH, pending input is processed, pending output is flushed and deflate returns with Z_STREAM_END if there was enough output space. If deflate returns with Z_OK or Z_BUF_ERROR, this function must be called again with Z_FINISH and more output space (updated avail_out) but no more input data, until it returns with Z_STREAM_END or an error. After deflate has returned Z_STREAM_END, the only possible operations on the stream are deflateReset or deflateEnd. Z_FINISH can be used in the first deflate call after deflateInit if all the compression is to be done in a single step. In order to complete in one call, avail_out must be at least the value returned by deflateBound (see below). Then deflate is guaranteed to return Z_STREAM_END. If not enough output space is provided, deflate will not return Z_STREAM_END, and it must be called again as described above. deflate() sets strm->adler to the Adler-32 checksum of all input read so far (that is, total_in bytes). If a gzip stream is being generated, then strm->adler will be the CRC-32 checksum of the input read so far. (See deflateInit2 below.) deflate() may update strm->data_type if it can make a good guess about the input data type (Z_BINARY or Z_TEXT). If in doubt, the data is considered binary. This field is only for information purposes and does not affect the compression algorithm in any manner. deflate() returns Z_OK if some progress has been made (more input processed or more output produced), Z_STREAM_END if all input has been consumed and all output has been produced (only when flush is set to Z_FINISH), Z_STREAM_ERROR if the stream state was inconsistent (for example if next_in or next_out was Z_NULL or the state was inadvertently written over by the application), or Z_BUF_ERROR if no progress is possible (for example avail_in or avail_out was zero). Note that Z_BUF_ERROR is not fatal, and deflate() can be called again with more input and more output space to continue compressing. */ ZEXTERN int ZEXPORT deflateEnd OF((z_streamp strm)); /* All dynamically allocated data structures for this stream are freed.

It may introduce some output latency (reading input without producing any output) except when forced to flush. The detailed semantics are as follows. inflate performs one or both of the following actions: - Decompress more input starting at next_in and update next_in and avail_in accordingly. If not all input can be processed (because there is not enough room in the output buffer), then next_in and avail_in are updated accordingly, and processing will resume at this point for the next call of inflate(). - Generate more output starting at next_out and update next_out and avail_out accordingly. inflate() provides as much output as possible, until there is no more input data or no more space in the output buffer (see below about the flush parameter). Before the call of inflate(), the application should ensure that at least one of the actions is possible, by providing more input and/or consuming more output, and updating the next_* and avail_* values accordingly. If the caller of inflate() does not provide both available input and available output space, it is possible that there will be no progress made. The application can consume the uncompressed output when it wants, for example when the output buffer is full (avail_out == 0), or after each call of inflate(). If inflate returns Z_OK and with zero avail_out, it must be called again after making room in the output buffer because there might be more output pending. The flush parameter of inflate() can be Z_NO_FLUSH, Z_SYNC_FLUSH, Z_FINISH, Z_BLOCK, or Z_TREES. Z_SYNC_FLUSH requests that inflate() flush as much output as possible to the output buffer. Z_BLOCK requests that inflate() stop if and when it gets to the next deflate block boundary. When decoding the zlib or gzip format, this will cause inflate() to return immediately after the header and before the first block. When doing a raw inflate, inflate() will go ahead and process the first block, and will return when it gets to the end of that block, or when it runs out of data. The Z_BLOCK option assists in appending to or combining deflate streams. To assist in this, on return inflate() always sets strm->data_type to the number of unused bits in the last byte taken from strm->next_in, plus 64 if inflate() is currently decoding the last block in the deflate stream, plus 128 if inflate() returned immediately after decoding an end-of-block code or decoding the complete header up to just before the first byte of the deflate stream. The end-of-block will not be indicated until all of the uncompressed data from that block has been written to strm->next_out. The number of unused bits may in general be greater than seven, except when bit 7 of data_type is set, in which case the number of unused bits will be less than eight. data_type is set as noted here every time inflate() returns for all flush options, and so can be used to determine the amount of currently consumed input in bits. The Z_TREES option behaves as Z_BLOCK does, but it also returns when the end of each deflate block header is reached, before any actual data in that block is decoded. This allows the caller to determine the length of the deflate block header for later use in random access within a deflate block. 256 is added to the value of strm->data_type when inflate() returns immediately after reaching the end of the deflate block header. inflate() should normally be called until it returns Z_STREAM_END or an error. However if all decompression is to be performed in a single step (a single call of inflate), the parameter flush should be set to Z_FINISH. In this case all pending input is processed and all pending output is flushed; avail_out must be large enough to hold all of the uncompressed data for the operation to complete. (The size of the uncompressed data may have been saved by the compressor for this purpose.) The use of Z_FINISH is not required to perform an inflation in one step. However it may be used to inform inflate that a faster approach can be used for the single inflate() call. Z_FINISH also informs inflate to not maintain a sliding window if the stream completes, which reduces inflate's memory footprint. If the stream does not complete, either because not all of the stream is provided or not enough output space is provided, then a sliding window will be allocated and inflate() can be called again to continue the operation as if Z_NO_FLUSH had been used. In this implementation, inflate() always flushes as much output as possible to the output buffer, and always uses the faster approach on the first call. So the effects of the flush parameter in this implementation are on the return value of inflate() as noted below, when inflate() returns early when Z_BLOCK or Z_TREES is used, and when inflate() avoids the allocation of memory for a sliding window when Z_FINISH is used. If a preset dictionary is needed after this call (see inflateSetDictionary below), inflate sets strm->adler to the Adler-32 checksum of the dictionary chosen by the compressor and returns Z_NEED_DICT; otherwise it sets strm->adler to the Adler-32 checksum of all output produced so far (that is, total_out bytes) and returns Z_OK, Z_STREAM_END or an error code as described below. At the end of the stream, inflate() checks that its computed Adler-32 checksum is equal to that saved by the compressor and returns Z_STREAM_END only if the checksum is correct. inflate() can decompress and check either zlib-wrapped or gzip-wrapped deflate data. The header type is detected automatically, if requested when initializing with inflateInit2(). Any information contained in the gzip header is not retained unless inflateGetHeader() is used. When processing gzip-wrapped deflate data, strm->adler32 is set to the CRC-32 of the output produced so far. The CRC-32 is checked against the gzip trailer, as is the uncompressed length, modulo 2^32. inflate() returns Z_OK if some progress has been made (more input processed or more output produced), Z_STREAM_END if the end of the compressed data has been reached and all uncompressed output has been produced, Z_NEED_DICT if a preset dictionary is needed at this point, Z_DATA_ERROR if the input data was corrupted (input stream not conforming to the zlib format or incorrect check value, in which case strm->msg points to a string with a more specific error), Z_STREAM_ERROR if the stream structure was inconsistent (for example next_in or next_out was Z_NULL, or the state was inadvertently written over by the application), Z_MEM_ERROR if there was not enough memory, Z_BUF_ERROR if no progress was possible or if there was not enough room in the output buffer when Z_FINISH is used. Note that Z_BUF_ERROR is not fatal, and inflate() can be called again with more input and more output space to continue decompressing. If Z_DATA_ERROR is returned, the application may then call inflateSync() to look for a good compression block if a partial recovery of the data is to be attempted. */ ZEXTERN int ZEXPORT inflateEnd OF((z_streamp strm)); /* All dynamically allocated data structures for this stream are freed. This function discards any unprocessed input and does not flush any pending output. inflateEnd returns Z_OK if success, or Z_STREAM_ERROR if the stream state was inconsistent. */ /* Advanced functions */ /* The following functions are needed only in some special applications. */ /* ZEXTERN int ZEXPORT deflateInit2 OF((z_streamp strm, int level, int method, int windowBits, int memLevel, int strategy)); This is another version of deflateInit with more compression options. The fields next_in, zalloc, zfree and opaque must be initialized before by the caller. The method parameter is the compression method. It must be Z_DEFLATED in this version of the library. The windowBits parameter is the base two logarithm of the window size (the size of the history buffer). It should be in the range 8..15 for this version of the library. Larger values of this parameter result in better compression at the expense of memory usage. The default value is 15 if deflateInit is used instead. For the current implementation of deflate(), a windowBits value of 8 (a window size of 256 bytes) is not supported. As a result, a request for 8 will result in 9 (a 512-byte window). In that case, providing 8 to inflateInit2() will result in an error when the zlib header with 9 is checked against the initialization of inflate(). The remedy is to not use 8 with deflateInit2() with this initialization, or at least in that case use 9 with inflateInit2(). windowBits can also be -8..-15 for raw deflate. In this case, -windowBits determines the window size. deflate() will then generate raw deflate data with no zlib header or trailer, and will not compute a check value. windowBits can also be greater than 15 for optional gzip encoding. Add 16 to windowBits to write a simple gzip header and trailer around the compressed data instead of a zlib wrapper. The gzip header will have no file name, no extra data, no comment, no modification time (set to zero), no header crc, and the operating system will be set to the appropriate value, if the operating system was determined at compile time. If a gzip stream is being written, strm->adler is a CRC-32 instead of an Adler-32. For raw deflate or gzip encoding, a request for a 256-byte window is rejected as invalid, since only the zlib header provides a means of transmitting the window size to the decompressor. The memLevel parameter specifies how much memory should be allocated for the internal compression state. memLevel=1 uses minimum memory but is slow and reduces compression ratio; memLevel=9 uses maximum memory for optimal speed. The default value is 8. See zconf.h for total memory usage as a function of windowBits and memLevel. The strategy parameter is used to tune the compression algorithm. Use the value Z_DEFAULT_STRATEGY for normal data, Z_FILTERED for data produced by a filter (or predictor), Z_HUFFMAN_ONLY to force Huffman encoding only (no string match), or Z_RLE to limit match distances to one (run-length encoding). Filtered data consists mostly of small values with a somewhat random distribution. In this case, the compression algorithm is tuned to compress them better. The effect of Z_FILTERED is to force more Huffman coding and less string matching; it is somewhat intermediate between Z_DEFAULT_STRATEGY and Z_HUFFMAN_ONLY. Z_RLE is designed to be almost as fast as Z_HUFFMAN_ONLY, but give better compression for PNG image data. The strategy parameter only affects the compression ratio but not the correctness of the compressed output even if it is not set appropriately. Z_FIXED prevents the use of dynamic Huffman codes, allowing for a simpler decoder for special applications. deflateInit2 returns Z_OK if success, Z_MEM_ERROR if there was not enough memory, Z_STREAM_ERROR if any parameter is invalid (such as an invalid method), or Z_VERSION_ERROR if the zlib library version (zlib_version) is incompatible with the version assumed by the caller (ZLIB_VERSION). msg is set to null if there is no error message. deflateInit2 does not perform any compression: this will be done by deflate(). */ ZEXTERN int ZEXPORT deflateSetDictionary OF((z_streamp strm, const Bytef *dictionary, uInt dictLength)); /* Initializes the compression dictionary from the given byte sequence without producing any compressed output.

The compressor and decompressor must use exactly the same dictionary (see inflateSetDictionary). The dictionary should consist of strings (byte sequences) that are likely to be encountered later in the data to be compressed, with the most commonly used strings preferably put towards the end of the dictionary. Using a dictionary is most useful when the data to be compressed is short and can be predicted with good accuracy; the data can then be compressed better than with the default empty dictionary. Depending on the size of the compression data structures selected by deflateInit or deflateInit2, a part of the dictionary may in effect be discarded, for example if the dictionary is larger than the window size provided in deflateInit or deflateInit2.

The default value is 15 if inflateInit is used instead. windowBits must be greater than or equal to the windowBits value provided to deflateInit2() while compressing, or it must be equal to 15 if deflateInit2() was not used. If a compressed stream with a larger window size is given as input, inflate() will return with the error code Z_DATA_ERROR instead of trying to allocate a larger window. windowBits can also be zero to request that inflate use the window size in the zlib header of the compressed stream. windowBits can also be -8..-15 for raw inflate. In this case, -windowBits determines the window size. inflate() will then process raw deflate data, not looking for a zlib or gzip header, not generating a check value, and not looking for any check values for comparison at the end of the stream. This is for use with other formats that use the deflate compressed data format such as zip. Those formats provide their own check values. If a custom format is developed using the raw deflate format for compressed data, it is recommended that a check value such as an Adler-32 or a CRC-32 be applied to the uncompressed data as is done in the zlib, gzip, and zip formats. For most applications, the zlib format should be used as is. Note that comments above on the use in deflateInit2() applies to the magnitude of windowBits. windowBits can also be greater than 15 for optional gzip decoding.

If a zlib stream is being decoded, then head->done is set to -1 to indicate that there will be no gzip header information forthcoming. Note that Z_BLOCK or Z_TREES can be used to force inflate() to return immediately after header processing is complete and before any actual data is decompressed. The text, time, xflags, and os fields are filled in with the gzip header contents. hcrc is set to true if there is a header CRC. (The header CRC was valid if done is set to one.) If extra is not Z_NULL, then extra_max contains the maximum number of bytes to write to extra. Once done is true, extra_len contains the actual extra field length, and extra contains the extra field, or that field truncated if extra_max is less than extra_len.

When any of extra, name, or comment are not Z_NULL and the respective field is not present in the header, then that field is set to Z_NULL to signal its absence. This allows the use of deflateSetHeader() with the returned structure to duplicate the header. However if those fields are set to allocated memory, then the application will need to save those pointers elsewhere so that they can be eventually freed. If inflateGetHeader is not used, then the header information is simply discarded. The header is always checked for validity, including the header CRC if present. inflateReset() will reset the process to discard the header information.

This is potentially more efficient than inflate() for file i/o applications, in that it avoids copying between the output and the sliding window by simply making the window itself the output buffer. inflate() can be faster on modern CPUs when used with large buffers. inflateBack() trusts the application to not change the output buffer passed by the output function, at least until inflateBack() returns. inflateBackInit() must be called first to allocate the internal state and to initialize the state with the user-provided window buffer. inflateBack() may then be used multiple times to inflate a complete, raw deflate stream with each call. inflateBackEnd() is then called to free the allocated state. A raw deflate stream is one with no zlib or gzip header or trailer. This routine would normally be used in a utility that reads zip or gzip files and writes out uncompressed files. The utility would decode the header and process the trailer on its own, hence this routine expects only the raw deflate stream to decompress. This is different from the default behavior of inflate(), which expects a zlib header and trailer around the deflate stream. inflateBack() uses two subroutines supplied by the caller that are then called by inflateBack() for input and output. inflateBack() calls those routines until it reads a complete deflate stream and writes out all of the uncompressed data, or until it encounters an error. The function's parameters and return types are defined above in the in_func and out_func typedefs. inflateBack() will call in(in_desc, &buf) which should return the number of bytes of provided input, and a pointer to that input in buf. If there is no input available, in() must return zero -- buf is ignored in that case -- and inflateBack() will return a buffer error. inflateBack() will call out(out_desc, buf, len) to write the uncompressed data buf[0..len-1]. out() should return zero on success, or non-zero on failure. If out() returns non-zero, inflateBack() will return with an error. Neither in() nor out() are permitted to change the contents of the window provided to inflateBackInit(), which is also the buffer that out() uses to write from. The length written by out() will be at most the window size. Any non-zero amount of input may be provided by in(). For convenience, inflateBack() can be provided input on the first call by setting strm->next_in and strm->avail_in. If that input is exhausted, then in() will be called. Therefore strm->next_in must be initialized before calling inflateBack(). If strm->next_in is Z_NULL, then in() will be called immediately for input. If strm->next_in is not Z_NULL, then strm->avail_in must also be initialized, and then if strm->avail_in is not zero, input will initially be taken from strm->next_in[0 .. strm->avail_in - 1]. The in_desc and out_desc parameters of inflateBack() is passed as the first parameter of in() and out() respectively when they are called. These descriptors can be optionally used to pass any information that the caller- supplied in() and out() functions need to do their job. On return, inflateBack() will set strm->next_in and strm->avail_in to pass back any unused input that was provided by the last in() call. The return values of inflateBack() can be Z_STREAM_END on success, Z_BUF_ERROR if in() or out() returned an error, Z_DATA_ERROR if there was a format error in the deflate stream (in which case strm->msg is set to indicate the nature of the error), or Z_STREAM_ERROR if the stream was not properly initialized. In the case of Z_BUF_ERROR, an input or output error can be distinguished using strm->next_in which will be Z_NULL only if in() returned an error. If strm->next_in is not Z_NULL, then the Z_BUF_ERROR was due to out() returning non-zero. (in() will always be called before out(), so strm->next_in is assured to be defined if out() returns non-zero.)

(See the description of deflateInit2 for more information about the strategy parameter.) 'T' will request transparent writing or appending with no compression and not using the gzip format. "a" can be used instead of "w" to request that the gzip stream that will be written be appended to the file. "+" will result in an error, since reading and writing to the same gzip file is not supported. The addition of "x" when writing will create the file exclusively, which fails if the file already exists. On systems that support it, the addition of "e" when reading or writing will set the flag to close the file on an execve() call. These functions, as well as gzip, will read and decode a sequence of gzip streams in a file. The append function of gzopen() can be used to create such a file. (Also see gzflush() for another way to do this.) When appending, gzopen does not test whether the file begins with a gzip stream, nor does it look for the end of the gzip streams to begin appending. gzopen will simply append a gzip stream to the existing file. gzopen can be used to read a file which is not in gzip format; in this case gzread will directly read from the file without decompression. When reading, this will be detected automatically by looking for the magic two- byte gzip header. gzopen returns NULL if the file could not be opened, if there was insufficient memory to allocate the gzFile state, or if an invalid mode was specified (an 'r', 'w', or 'a' was not provided, or '+' was provided). errno can be checked to determine if the reason gzopen failed was that the file could not be opened. */ ZEXTERN gzFile ZEXPORT gzdopen OF((int fd, const char *mode)); /* gzdopen associates a gzFile with the file descriptor fd.

If you want to keep fd open, use fd = dup(fd_keep); gz = gzdopen(fd, mode);. The duplicated descriptor should be saved to avoid a leak, since gzdopen does not close fd if it fails. If you are using fileno() to get the file descriptor from a FILE *, then you will have to use dup() to avoid double-close()ing the file descriptor.

Type "fossil ui" and Fossil automatically opens a web browser to a page that shows detailed graphical history and status information on that project. .HP 3. .B Self-Contained - Fossil is a single self-contained stand-alone executable. To install, simply download a precompiled binary for Linux, Mac, OpenBSD, or Windows and put it on your $PATH. Easy-to-compile source code is available for users on other platforms. .HP 4. .B Simple Networking - No custom protocols or TCP ports. Fossil uses plain old HTTP (or HTTPS or SSH) for all network communications, so it works fine from behind restrictive firewalls, including proxies. The protocol is bandwidth efficient to the point that Fossil can be used comfortably over dial-up or over the exceedingly slow Wifi on airliners. .HP 5. .B CGI/SCGI Enabled - No server is required, but if you want to set one up, Fossil supports four easy server configurations. .HP 6. .B Autosync - Fossil supports "autosync" mode which helps to keep projects moving forward by reducing the amount of needless forking and merging often associated with distributed projects. .HP 7. .B Robust & Reliable - Fossil stores content using an enduring file format in an SQLite database so that transactions are atomic even if interrupted by a power loss or system crash. Automatic self-checks verify that all aspects of the repository are consistent prior to each commit. .HP 8. .B Free and Open-Source - Uses the 2-clause BSD license. .SH DOCUMENTATION http://www.fossil-scm.org/ .br .B fossil \fIui\fR |

There are five key files in each subdirectory: * `css.txt` → The CSS for the skin * `details.txt` → Skin-specific settings * `footer.txt` → Text of the Content Footer for each page * `header.txt` → Text of the Content Header for each page * `js.txt` → Javascript included in the Content Footer To improve an existing built-in skin, simply edit the appropriate files and recompile. To add a new skin: 1. Create a new subdirectory under skins/. (The new directory is called "skins/newskin" below but you should use a new original name, of course.) 2. Add files skins/newskin/css.txt, skins/newskin/details.txt, skins/newskin/footer.txt, skins/newskin/header.txt, and skins/newskin/js.txt. Be sure to "fossil add" these files. 3. Go to the src/ directory and rerun "tclsh makemake.tcl". This step rebuilds the various makefiles so that they have dependencies on the skin files you just installed. 4. Edit the BuiltinSkin[] array near the top of the src/skins.c source file so that it describes and references the "newskin" skin. 5. Type "make" to rebuild. See the [custom skin documentation](../www/customskin.md) for more information. Development Hints ----------------- One way to develop a new skin is to copy the baseline files (css.txt, details.txt, footer.txt, header.txt, and js.txt) into a working directory $WORKDIR then launch Fossil with a command-line option "--skin $WORKDIR". Example: cp -r skins/default newskin fossil ui --skin ./newskin When the argument to --skin contains one or more '/' characters, the appropriate skin files are read from disk from the directory specified. So after launching fossil as shown above, you can edit the newskin/*.txt files using your favorite text editor, then press Reload on your browser to see immediate results. |

The skin includes custom icons for the file browser and the WYSIWYG editor, which are embedded directly in the css as base64 blobs. For convenience, they are also provided as standalone files in the images subdirectory. This skin was contributed by Antoine Chavasse. This theme is loosely based upon, and still contains some elements from the Blitz theme by James Moger. This theme embeds & uses a modified copy of [Normalize 3.0.2](https://necolas.github.io/normalize.css/) which is distributed under an [MIT license](https://github.com/necolas/normalize.css/blob/master/LICENSE.md). This theme embeds & uses a modified copy of [Skeleton](http://getskeleton.com) which is distributed under an [MIT license](https://github.com/dhg/Skeleton/blob/master/LICENSE.md). The sass version of Skeleton used in this project was made by [Seth Coelen](https://github.com/whatsnewsaes). |

This theme embeds & uses an unmodified copy of [Normalize 3.0.2](https://necolas.github.io/normalize.css/) which is distributed under an [MIT license](https://github.com/necolas/normalize.css/blob/master/LICENSE.md). This theme uses half of a heavily-modified version of [Skeleton](http://getskeleton.com) which is distributed under an [MIT license](https://github.com/dhg/Skeleton/blob/master/LICENSE.md). None of the responsive elements (media queries) are included at this time. The font used in the included Fossil logo image is [Trillium Web Light](http://www.google.com/fonts/specimen/Titillium+Web) @ 48px HTML color code #456a7a. The RSS feed icon is sourced from [Font-Awesome](https://fortawesome.github.io/Font-Awesome/icons) by Dave Gandy and is distributed under the [SIL OFL 1.1 ](http://scripts.sil.org/cms/scripts/page.php?site_id=nrsi&id=OFL) license. |

This theme embeds & uses an unmodified copy of [Normalize 3.0.2](https://necolas.github.io/normalize.css/) which is distributed under an [MIT license](https://github.com/necolas/normalize.css/blob/master/LICENSE.md). This theme uses half of a heavily-modified version of [Skeleton](http://getskeleton.com) which is distributed under an [MIT license](https://github.com/dhg/Skeleton/blob/master/LICENSE.md). None of the responsive elements (media queries) are included at this time. The font used in the included Fossil logo image is [Trillium Web Light](http://www.google.com/fonts/specimen/Titillium+Web) @ 48px HTML color code #456a7a. The RSS feed icon is sourced from [Font-Awesome](https://fortawesome.github.io/Font-Awesome/icons) by Dave Gandy and is distributed under the [SIL OFL 1.1 ](http://scripts.sil.org/cms/scripts/page.php?site_id=nrsi&id=OFL) license. |

These command are particularly useful in ** conjunction with the "max-loadavg" setting which cannot ** otherwise be set globally. ** ** server Run the "ui" or "server" commands on all repositories. ** ui The root URI gives a listing of all repos. ** ** ** In addition, the following maintenance operations are supported: ** ** add Add all the repositories named to the set of repositories ** tracked by Fossil. Normally Fossil is able to keep up with ** this list by itself, but sometimes it can benefit from this ** hint if you rename repositories. ** ** ignore Arguments are repositories that should be ignored by ** subsequent clean, extras, list, pull, push, rebuild, and ** sync operations. The -c|--ckout option causes the listed ** local checkouts to be ignored instead. ** ** list | ls Display the location of all repositories. The -c|--ckout ** option causes all local checkouts to be listed instead. ** ** Repositories are automatically added to the set of known repositories ** when one of the following commands are run against the repository: ** clone, info, pull, push, or sync. Even previously ignored repositories ** are added back to the list of repositories by these commands. ** ** Options: ** --showfile Show the repository or checkout being operated upon. ** --dontstop Continue with other repositories even after an error. ** --dry-run If given, display instead of run actions. */ void all_cmd(void){ int n;

Examples of ** backoffice processing includes: ** ** * Sending alerts and notifications ** * Processing the email queue ** * Handling post-receive hooks ** * Automatically syncing to peer repositories ** ** Backoffice processing is automatically started whenever there are ** changes to the repository. The backoffice process dies off after ** a period of inactivity. ** ** Steps are taken to ensure that only a single backoffice process is ** running at a time. Otherwise, there could be race conditions that ** cause adverse effects such as multiple alerts for the same changes. ** ** At the same time, we do not want a backoffice process to run forever. ** Backoffice processes should die off after doing whatever work they need ** to do. In this way, we avoid having lots of idle processes in the ** process table, doing nothing on rarely accessed repositories, and ** if the Fossil binary is updated on a system, the backoffice processes ** will restart using the new binary automatically. ** ** At any point in time there should be at most two backoffice processes. ** There is a main process that is doing the actually work, and there is ** a second stand-by process that is waiting for the main process to finish ** and that will become the main process after a delay. ** ** After any successful web page reply, the backoffice_check_if_needed() ** routine is called. That routine checks to see if both one or both of ** the backoffice processes are already running. That routine remembers the ** status in a global variable. ** ** Later, after the repository database is closed, the ** backoffice_run_if_needed() routine is called. If the prior call ** to backoffice_check_if_needed() indicated that backoffice processing ** might be required, the run_if_needed() attempts to kick off a backoffice ** process. ** ** All work performance by the backoffice is in the backoffice_work() ** routine. */ #if defined(_WIN32) # if defined(_WIN32_WINNT) # undef _WIN32_WINNT # endif # define _WIN32_WINNT 0x501 #endif #include "config.h" #include "backoffice.h" #include <time.h> #if defined(_WIN32) # include <windows.h> # include <stdio.h> # include <process.h> # if defined(__MINGW32__) # include <wchar.h> # endif # define GETPID (int)GetCurrentProcessId #else # include <unistd.h> # include <sys/types.h> # include <signal.h> # include <errno.h> # include <sys/time.h> # include <sys/resource.h> # include <fcntl.h> # define GETPID getpid #endif #include <time.h> /* ** The BKOFCE_LEASE_TIME is the amount of time for which a single backoffice ** processing run is valid.

The header information is a subset of that ** shown by the info command, and the footer shows if there are any forks. ** Change type classification is always enabled for the status command. ** ** Each line of output is the name of a changed file, with paths shown ** according to the "relative-paths" setting, unless overridden by the ** --abs-paths or --rel-paths options. ** ** By default, all changed files are selected for display. This behavior ** can be overridden by using one or more filter options (listed below), ** in which case only files with the specified change type(s) are shown. ** As a special case, the --no-merge option does not inhibit this default. ** This default shows exactly the set of changes that would be checked ** in by the commit command. ** ** If no filter options are used, or if the --merge option is used, the ** artifact hash of each merge contributor check-in version is displayed at ** the end of the report. The --no-merge option is useful to display the ** default set of changed files without the merge contributors. ** ** If change type classification is enabled, each output line starts with ** a code describing the file's change type, e.g. EDITED or RENAMED. It ** is enabled by default unless exactly one change type is selected. For ** the purposes of determining the default, --changed counts as selecting ** one change type. The default can be overridden by the --classify or ** --no-classify options. ** ** --edited and --updated produce disjoint sets. --updated shows a file ** only when it is identical to that of its merge contributor, and the ** change type classification is UPDATED_BY_MERGE or UPDATED_BY_INTEGRATE. ** If the file had to be merged with any other changes, it is considered ** to be merged or conflicted and therefore will be shown by --edited, not ** --updated, with types EDITED or CONFLICT. The --changed option can be ** used to display the union of --edited and --updated. ** ** --differ is so named because it lists all the differences between the ** checked-out version and the checkout directory. In addition to the ** default changes (excluding --merge), it lists extra files which (if ** ignore-glob is set correctly) may be worth adding.

It is opaque to clients, and only the cson public API should be used for setting or inspecting their values. This class is opaque because stack-based usage can easily cause leaks if one does not intimately understand the underlying internal memory management (which sometimes changes). It is (as of 20110323) legal to insert a given value instance into multiple containers (they will share ownership using reference counting) as long as those insertions do not cause cycles. However, be very aware that such value re-use uses a reference to the original copy, meaning that if its value is changed once, it is changed everywhere. Also beware that multi-threaded write operations on such references leads to undefined behaviour. PLEASE read the ACHTUNGEN below... ACHTUNG #1: cson_values MUST NOT form cycles (e.g. via object or array entries). Not abiding th Holy Law Of No Cycles will lead to double-frees and the like (i.e. undefined behaviour, likely crashes due to infinite recursion or stepping on invalid (freed) pointers). ACHTUNG #2: ALL cson_values returned as non-const cson_value pointers from any public functions in the cson API are to be treated as if they are heap-allocated, and MUST be freed by client by doing ONE of: - Passing it to cson_value_free(). - Adding it to an Object or Array, in which case the object/array takes over ownership. As of 20110323, a value may be inserted into a single container multiple times, or into multiple containers, in which case they all share ownership (via reference counting) of the original value (meaning any changes to it are visible in all references to it). Each call to cson_value_new_xxx() MUST eventually be followed up by one of those options. Some cson_value_new_XXX() implementations do not actually allocate memory, but this is an internal implementation detail. Client code MUST NOT rely on this behaviour and MUST treat each object returned by such a function as if it was a freshly-allocated copy (even if their pointer addresses are the same). ACHTUNG #3: Note that ACHTUNG #2 tells us that we must always free (or transfer ownership of) all pointers returned bycson_value_new_xxx(), but that two calls to (e.g.) cson_value_new_bool(1) will (or might) return the same address.

This is a low-level operation and should not normally be used by client code without understanding exactly what side-effects it introduces. Mis-use can lead to premature destruction or cause a value instance to never be properly destructed (i.e. a memory leak). This function is probably only useful for the following cases: - You want to hold a reference to a value which is itself contained in one or more containers, and you need to be sure that your reference outlives the container(s) and/or that you can free your copy of the reference without invaliding any references to the same value held in containers. - You want to implement "value sharing" behaviour without using an object or array to contain the shared value. This can be used to ensure the lifetime of the shared value instance. Each sharing point adds a reference and simply passed the value to cson_value_free() when they're done. The object will be kept alive for other sharing points which added a reference. Normally any such value handles would be invalidated when the parent container(s) is/are cleaned up, but this function can be used to effectively delay the cleanup. This function, at its lowest level, increments the value's reference count by 1. To decrement the reference count, pass the value to cson_value_free(), after which the value must be considered, from the perspective of that client code, to be destroyed (though it will not be if there are still other live references to it). cson_value_free() will not _actually_ destroy the value until its reference count drops to 0. Returns 0 on success. The only error conditions are if v is NULL (cson_rc.ArgError) or if the reference increment would overflow (cson_rc.RangeError). In theory a client would get allocation errors long before the reference count could overflow (assuming those reference counts come from container insertions, as opposed to via this function). Insider notes which clients really need to know: For shared/constant value instances, such as those returned by cson_value_true() and cson_value_null(), this function has no side effects - it does not actually modify the reference count because (A) those instances are shared across all client code and (B) those objects are static and never get cleaned up. However, that is an implementation detail which client code should not rely on. In other words, if you call cson_value_add_reference() 3 times using the value returned by cson_value_true() (which is incidentally a shared cson_value instance), you must eventually call cson_value_free() 3 times to (semantically) remove those references. However, internally the reference count for that specific cson_value instance will not be modified and those objects will never be freed (they're stack-allocated). It might be interesting to note that newly-created objects have a reference count of 0 instead of 1. This is partly because if the initial reference is counted then it makes ownership problematic when inserting values into containers. e.g. consider the following code: @code // ACHTUNG: this code is hypothetical and does not reflect // what actually happens! cson_value * v = cson_value_new_integer( 42 ); // v's refcount = 1 cson_array_append( myArray, v ); // v's refcount = 2 @endcode If that were the case, the client would be forced to free his own reference after inserting it into the container (which is a bit counter-intuitive as well as intrusive). It would look a bit like the following and would have to be done after every create/insert operation: @code // ACHTUNG: this code is hypothetical and does not reflect // what actually happens! cson_array_append( myArray, v ); // v's refcount = 2 cson_value_free( v ); // v's refcount = 1 @endcode (As i said: it's counter-intuitive and intrusive.) Instead, values start with a refcount of 0 and it is only increased when the value is added to an object/array container or when this function is used to manually increment it. cson_value_free() treats a refcount of 0 or 1 equivalently, destroying the value instance. The only semantic difference between 0 and 1, for purposes of cleaning up, is that a value with a non-0 refcount has been had its refcount adjusted, whereas a 0 refcount indicates a fresh, "unowned" reference. */ int cson_value_add_reference( cson_value * v ); #if 0 /** DO NOT use this unless you know EXACTLY what you're doing.

Ownership of the clone is identical t transfered to the caller, who must eventually free the value using cson_value_free() or add it to a container object/array to transfer ownership to the container. The returned object will be of the same logical type as orig. ACHTUNG: if orig contains any cyclic references at any depth level this function will endlessly recurse. (Having _any_ cyclic references violates this library's requirements.) Returns NULL if orig is NULL or if cloning fails. Assuming that orig is in a valid state, the only "likely" error case is that an allocation fails while constructing the clone. In other words, if cloning fails due to something other than an allocation error then either orig is in an invalid state or there is a bug. When this function clones Objects or Arrays it shares any immutable values (including object keys) between the parent and the clone. Mutable values (Objects and Arrays) are copied, however. For example, if we clone: @code { a: 1, b: 2, c:["hi"] } @endcode The cloned object and the array "c" would be a new Object/Array instances but the object keys (a,b,b) and the values of (a,b), as well as the string value within the "c" array, would be shared between the original and the clone. The "c" array itself would be deeply cloned, such that future changes to the clone are not visible to the parent, and vice versa, but immutable values within the array are shared (in this case the string "hi"). The justification for this heuristic is that immutable values can never be changed, so there is no harm in sharing them across clones. Additionally, such types can never contribute to cycles in a JSON tree, so they are safe to share this way. Objects and Arrays, on the other hand, can be modified later and can contribute to cycles, and thus the clone needs to be an independent instance. Note, however, that if this function directly passed a non-Object/Array, that value is deeply cloned.

If it's an ID, the DOM element must support .value to get the content. - data-f-preview-to: the DOM element id of the target "previewer" element, WITH a leading '#', or the name of a method (see below). - data-f-preview-via: the name of a method (see below). - OPTIONAL data-f-preview-as-text: a numeric value. Explained below. Each element gets a click handler added to it which does the following: 1) Reads the content from its data-f-preview-from element or, if that property refers to a method, calls the method without arguments and uses its result as the content. 2) Passes the content to methodNamespace[f-data-post-via](content,callback). f-data-post-via is responsible for submitting the preview HTTP request, including any parameters the request might require. When the response arrives, it must pass the content of the response to its 2nd argument, an auto-generated callback installed by this mechanism which... 3) Assigns the response text to the data-f-preview-to element or passes it to the function methodNamespace[f-data-preview-to](content), as appropriate.

It acts by modifying a button to require two clicks within a certain time, with the second click acting as a confirmation of the first. If the second click does not come within a specified timeout then the action is not confirmed. Usage: fossil.confirmer(domElement, options); Usually: fossil.confirmer(element, { onconfirm: function(){ // this === the element. // Do whatever the element would normally do when // clicked. } }); Options: .initialText = initial text of the element. Defaults to the result of the element's .value (for INPUT tags) or innerHTML (for everything else). After the timeout/tick count expires, or if the user confirms the operation, the element's text is re-set to this value. .confirmText = text to show when in "confirm mode". Default=("Confirm: "+initialText), or something similar. .timeout = Number of milliseconds to wait for confirmation. Default=3000. Alternately, use a combination of .ticks and .ticktime. .onconfirm = function to call when clicked in confirm mode. Default = undefined. The function's "this" is the DOM element to which the countdown applies. .ontimeout = function to call when confirm is not issued. Default = undefined. The function's "this" is the DOM element to which the countdown applies. .onactivate = function to call when item is clicked, but only if the item is not currently in countdown mode. This is called (and must return) before the countdown starts. The function's "this" is the DOM element to which the countdown applies. This can be used, e.g., to change the element's text or CSS classes. .classInitial = optional CSS class string (default='') which is added to the element during its "initial" state (the state it is in when it is not waiting on a timeout). When the target is activated (waiting on a timeout) this class is removed. In the case of a timeout, this class is added *before* the .ontimeout handler is called. .classWaiting = optional CSS class string (default='') which is added to the target when it is waiting on a timeout. When the target leaves timeout-wait mode, this class is removed. When timeout-wait mode is entered, this class is added *before* the .onactivate handler is called. .ticktime = a number of ms to wait per tick (see the next item). Default = 1000. .ticks = a number of "ticks" to wait, as an alternative to .timeout. When this mode is active, the ontick callback will be triggered immediately before each tick, including the first one. If both .ticks and .timeout are set, only one will be used, but which one is unspecified. If passed a ticks value with a truncated integer value of 0 or less, it will throw an exception (e.g. that also applies if it's passed 0.5). .ontick = when using .ticks, this callback is passed the current tick number before each tick, and its "this" is the target element. On each subsequent call, the tick count will be reduced by 1, and it is passed 0 after the final tick expires or when the action has been confirmed, immediately before the onconfirm or ontimeout callback. The intention of the callback is to update the label of the target element. If .ticks is set but .ontick is not then a default implementation is used which updates the element with the .confirmText, prepending a countdown to it. .debug = boolean. If truthy, it sends some debug output to the dev console to track what it's doing. Various notes: - To change the default option values, modify the fossil.confirmer.defaultOpts object. - Exceptions triggered via the callbacks are caught and emitted to the dev console if the debug option is enabled, but are otherwise ignored. - Due to the nature of multi-threaded code, it is potentially possible that confirmation and timeout actions BOTH happen if the user triggers the associated action at "just the right millisecond" before the timeout is triggered. TODO: add an invert option which activates if the timeout is reached and "times out" if the element is clicked again. e.g. a button which says "Saving..." and cancels the op if it's clicked again, else it saves after X time/ticks. Terse Change history: - 20200507: - Add a tick-based countdown in order to more easily support updating the target element with the countdown. - 20200506: - Ported from jQuery to plain JS. - 20181112: - extended to support certain INPUT elements. - made default opts configurable. - 20070717: initial jQuery-based impl. */ (function(F/*the fossil object*/){ F.confirmer = function f(elem,opt){ const dbg = opt.debug ? function(){console.debug.apply(console,arguments)} : function(){}; dbg("confirmer opt =",opt); if(!f.Holder){ f.isInput = (e)=>/^(input|textarea)$/i.test(e.nodeName); f.Holder = function(target,opt){ const self = this; this.target = target; this.opt = opt; this.timerID = undefined; this.state = this.states.initial; const isInput = f.isInput(target); const updateText = function(msg){ if(isInput) target.value = msg; else target.innerHTML = msg; } updateText(this.opt.initialText); if(this.opt.ticks && !this.opt.ontick){ this.opt.ontick = function(tick){ updateText("("+tick+") "+self.opt.confirmText); }; } this.setClasses(false); this.doTimeout = function() { if(this.timerID){ clearTimeout( this.timerID ); delete this.timerID; } if( this.state != this.states.waiting ) { // it was already confirmed return; } this.setClasses( false ); this.state = this.states.initial; dbg("Timeout triggered."); if( this.opt.ontick ){ try{this.opt.ontick.call(this.target, 0)} catch(e){dbg("ontick EXCEPTION:",e)} } if( this.opt.ontimeout ) { try{this.opt.ontimeout.call(this.target)} catch(e){dbg("ontimeout EXCEPTION:",e)} } updateText(this.opt.initialText); }; target.addEventListener( 'click', function(){ switch( self.state ) { case( self.states.waiting ): /* Cancel the wait on confirmation */ if( undefined !== self.timerID ){ clearTimeout( self.timerID ); delete self.timerID; } self.state = self.states.initial; self.setClasses( false ); dbg("Confirmed"); if( self.opt.ontick ){ try{self.opt.ontick.call(self.target,0)} catch(e){dbg("ontick EXCEPTION:",e)} } if( self.opt.onconfirm ){ try{self.opt.onconfirm.call(self.target)} catch(e){dbg("onconfirm EXCEPTION:",e)} } updateText(self.opt.initialText); break; case( self.states.initial ): /* Enter the waiting-on-confirmation state... */ if(self.opt.ticks) self.opt.currentTick = self.opt.ticks; self.setClasses( true ); self.state = self.states.waiting; updateText( self.opt.confirmText ); if( self.opt.onactivate ) self.opt.onactivate.call( self.target ); if( self.opt.ontick ) self.opt.ontick.call(self.target, self.opt.currentTick); if(self.opt.timeout){ dbg("Waiting "+self.opt.timeout+"ms on confirmation..."); self.timerID = setTimeout(()=>self.doTimeout(),self.opt.timeout ); }else if(self.opt.ticks){ dbg("Waiting on confirmation for "+self.opt.ticks +" ticks of "+self.opt.ticktime+"ms each..."); self.timerID = setInterval(function(){ if(0===--self.opt.currentTick) self.doTimeout(); else{ try{self.opt.ontick.call(self.target, self.opt.currentTick)} catch(e){dbg("ontick EXCEPTION:",e)} } },self.opt.ticktime); } break; default: // can't happen. break; } }, false ); }; f.Holder.prototype = { states:{initial: 0, waiting: 1}, setClasses: function(activated) { if(activated) { if( this.opt.classWaiting ) { this.target.classList.add( this.opt.classWaiting ); } if( this.opt.classInitial ) { this.target.classList.remove( this.opt.classInitial ); } }else{ if( this.opt.classInitial ) { this.target.classList.add( this.opt.classInitial ); } if( this.opt.classWaiting ) { this.target.classList.remove( this.opt.classWaiting ); } } } }; }/*static init*/ opt = F.mergeLastWins(f.defaultOpts,{ initialText: ( f.isInput(elem) ? elem.value : elem.innerHTML ) || "PLEASE SET .initialText" },opt); if(!opt.confirmText){ opt.confirmText = "Confirm: "+opt.initialText; } if(opt.ticks){ delete opt.timeout; opt.ticks = 0 | opt.ticks /* ensure it's an integer */; if(opt.ticks<=0){ throw new Error("ticks must be >0"); } if(opt.ticktime <= 0) opt.ticktime = 1000; }else{ delete opt.ontick; delete opt.ticks; } new f.Holder(elem,opt); return this; }; /** The default options for initConfirmer().

In the context of the callback, the options object is "this", noting that this call may have amended the options object with state other than what the caller provided. - onerror: callback(Error object) (default = output error message to console.error() and fossil.error()). Triggered if the request generates any response other than HTTP 200 or suffers a connection error or timeout while awaiting a response. In the context of the callback, the options object is "this". - method: 'POST' | 'GET' (default = 'GET'). CASE SENSITIVE! - payload: anything acceptable by XHR2.send(ARG) (DOMString, Document, FormData, Blob, File, ArrayBuffer), or a plain object or array, either of which gets JSON.stringify()'d. If payload is set then the method is automatically set to 'POST'. By default XHR2 will set the content type based on the payload type. If an object/array is converted to JSON, the contentType option is automatically set to 'application/json', and if JSON.stringify() of that value fails then the exception is propagated to this function's caller. - contentType: Optional request content type when POSTing. Ignored if the method is not 'POST'. - responseType: optional string. One of ("text", "arraybuffer", "blob", or "document") (as specified by XHR2). Default = "text". As an extension, it supports "json", which tells it that the response is expected to be text and that it should be JSON.parse()d before passing it on to the onload() callback. If parsing of such an object fails, the onload callback is not called, and the onerror() callback is passed the exception from the parsing error. - urlParams: string|object. If a string, it is assumed to be a URI-encoded list of params in the form "key1=val1&key2=val2...", with NO leading '?'. If it is an object, all of its properties get converted to that form. Either way, the parameters get appended to the URL before submitting the request. - responseHeaders: If true, the onload() callback is passed an additional argument: a map of all of the response headers. If it's a string value, the 2nd argument passed to onload() is instead the value of that single header. If it's an array, it's treated as a list of headers to return, and the 2nd argument is a map of those header values. When a map is passed on, all of its keys are lower-cased. When a given header is requested and that header is set multiple times, their values are (per the XHR docs) concatenated together with ", " between them. - beforesend/aftersend: optional callbacks which are called without arguments immediately before the request is submitted and immediately after it is received, regardless of success or error. In the context of the callback, the options object is the "this". These can be used to, e.g., keep track of in-flight requests and update the UI accordingly, e.g. disabling/enabling DOM elements. Any exceptions triggered by beforesend/aftersend are caught and silently ignored. - timeout: integer in milliseconds specifying the XHR timeout duration. Default = fossil.fetch.timeout. When an options object does not provide onload/onerror/beforesend/aftersend handlers of its own, this function falls to defaults which are member properties of this function with the same name, e.g. fossil.fetch.onload(). The default onload/onerror implementations route the data through the dev console and (for onerror()) through fossil.error(). The default beforesend/aftersend are no-ops. Individual pages may overwrite those members to provide default implementations suitable for the page's use, e.g. keeping track of how many in-flight ajax requests are pending. Any exceptions thrown in an beforesend/aftersend handler are current ignored (feature or bug?). Note that this routine may add properties to the 2nd argument, so that instance should not be kept around for later use. Returns this object, noting that the XHR request is asynchronous, and still in transit (or has yet to be sent) when that happens. */ window.fossil.fetch = function f(uri,opt){ const F = fossil; if(!f.onload){ f.onload = (r)=>console.debug('fossil.fetch() XHR response:',r); } if(!f.onerror){ f.onerror = function(e/*exception*/){ console.error("fossil.fetch() XHR error:",e); if(e instanceof Error) F.error('Exception:',e); else F.error("Unknown error in handling of XHR request."); }; }/*f.onerror()*/ if(!f.parseResponseHeaders){ f.parseResponseHeaders = function(h){ const rc = {}; if(!h) return rc; const ar = h.trim().split(/[\r\n]+/); ar.forEach(function(line) { const parts = line.split(': '); const header = parts.shift(); const value = parts.join(': '); rc[header.toLowerCase()] = value; }); return rc; }; } if('/'===uri[0]) uri = uri.substr(1); if(!opt) opt = {}; else if('function'===typeof opt) opt={onload:opt}; if(!opt.onload) opt.onload = f.onload; if(!opt.onerror) opt.onerror = f.onerror; if(!opt.beforesend) opt.beforesend = f.beforesend; if(!opt.aftersend) opt.aftersend = f.aftersend; let payload = opt.payload, jsonResponse = false; if(undefined!==payload){ opt.method = 'POST'; if(!(payload instanceof FormData) && !(payload instanceof Document) && !(payload instanceof Blob) && !(payload instanceof File) && !(payload instanceof ArrayBuffer) && ('object'===typeof payload || payload instanceof Array)){ payload = JSON.stringify(payload); opt.contentType = 'application/json'; } } const url=[F.repoUrl(uri,opt.urlParams)], x=new XMLHttpRequest(); if('json'===opt.responseType){ /* 'json' is an extension to the supported XHR.responseType list.

that several fossil JS APIs have been installed: fossil.fetch, fossil.dom, fossil.tabs, fossil.storage, fossil.confirmer. Custom events which can be listened for via fossil.page.addEventListener(): - Event 'fileedit-file-loaded': passes on information when it loads a file (whether from the network or its internal local-edit cache), in the form of an "finfo" object: { filename: string, checkin: UUID string, branch: branch name of UUID, isExe: bool, true only for executable files mimetype: mimetype string, as determined by the fossil server. } The internal docs and code frequently use the term "finfo", and such references refer to an object with that form. The fossil.page.fileContent() method gets or sets the current file content for the page. - Event 'fileedit-committed': is fired when a commit completes, passing on the same info as fileedit-file-loaded. - Event 'fileedit-content-replaced': when the editor's content is replaced, as opposed to it being edited via user interaction. This normally happens via selecting a file to load. The event detail is the fossil.page object, not the current file content. - Event 'fileedit-preview-updated': when the preview is refreshed from the server, this event passes on information about the preview change in the form of an object: { element: the DOM element which contains the content preview. mimetype: the fossil-reported content mimetype. previewMode: a string describing the preview mode: see the fossil.page.previewModes map for the values. This can be used to determine whether, e.g., the content is suitable for applying a 3rd-party code highlighting API to. } Here's an example which can be used with the highlightjs code highlighter to update the highlighting when the preview is refreshed in "wiki" mode (which includes fossil-native wiki and markdown): fossil.page.addEventListener( 'fileedit-preview-updated', (ev)=>{ if(ev.detail.previewMode==='wiki'){ ev.detail.element.querySelectorAll( 'code[class^=language-]' ).forEach((e)=>hljs.highlightBlock(e)); } } ); */ const E = (s)=>document.querySelector(s), D = F.dom, P = F.page; P.config = { defaultMaxStashSize: 7 }; /** $stash is an internal-use-only object for managing "stashed" local edits, to help avoid that users accidentally lose content by switching tabs or following links or some such. The basic theory of operation is... All "stashed" state is stored using fossil.storage. - When the current file content is modified by the user, the current stathe of the current P.finfo and its the content is stashed. For the built-in editor widget, "changes" is notified via a 'change' event. For a client-side custom widget, the client needs to call P.stashContentChange() when their widget triggers the equivalent of a 'change' event. - For certain non-content updates (as of this writing, only the is-executable checkbox), only the P.finfo stash entry is updated, not the content (unless the content has not yet been stashed, in which case it is also stashed so that the stash always has matching pairs of finfo/content). - When saving, the stashed entry for the previous version is removed from the stash. - When "loading", we use any stashed state for the given checkin/file combination. When forcing a re-load of content, any stashed entry for that combination is removed from the stash. - Every time P.stashContentChange() updates the stash, it is pruned to $stash.prune.defaultMaxCount most-recently-updated entries. - This API often refers to "finfo objects." Those are objects with a minimum of {checkin,filename} properties (which must be valid), and a combination of those two properties is used as basis for the stash keys for any given checkin/filename combination. The structure of the stash is a bit convoluted for efficiency's sake: we store a map of file info (finfo) objects separately from those files' contents because otherwise we would be required to JSONize/de-JSONize the file content when stashing/restoring it, and that would be horribly inefficient (meaning "battery-consuming" on mobile devices). */ const $stash = { keys: { index: F.page.name+'.index' }, /** index: { "CHECKIN_HASH:FILENAME": {file info w/o content} ... } In F.storage we... - Store this.index under the key this.keys.index. - Store each file's content under the key (P.name+'/CHECKIN_HASH:FILENAME').

If an element is disabled before an XHR starts, this code "should" notice that and not include it in the to-re-enable list.

Curiously, the all-or-nothing re-enabling implemented here does not re-enable that particular selection list.

/wikiedit app. Requires that the fossil JS bootstrapping is complete and that several fossil JS APIs have been installed: fossil.fetch, fossil.dom, fossil.tabs, fossil.storage, fossil.confirmer. Custom events which can be listened for via fossil.page.addEventListener(): - Event 'wiki-page-loaded': passes on information when it loads a wiki (whether from the network or its internal local-edit cache), in the form of an "winfo" object: { name: string, mimetype: mimetype string, type: "normal" | "tag" | "checkin" | "branch" | "sandbox", version: UUID string or null for a sandbox page or new page, parent: parent UUID string or null if no parent, isEmpty: true if page has no content (is "deleted"). content: string, optional in most contexts } The internal docs and code frequently use the term "winfo", and such references refer to an object with that form. The fossil.page.wikiContent() method gets or sets the current file content for the page. - Event 'wiki-saved': is fired when a commit completes, passing on the same info as wiki-page-loaded. - Event 'wiki-content-replaced': when the editor's content is replaced, as opposed to it being edited via user interaction. This normally happens via selecting a file to load. The event detail is the fossil.page object, not the current file content. - Event 'wiki-preview-updated': when the preview is refreshed from the server, this event passes on information about the preview change in the form of an object: { element: the DOM element which contains the content preview. mimetype: the page's mimetype. } Here's an example which can be used with the highlightjs code highlighter to update the highlighting when the preview is refreshed in "wiki" mode (which includes fossil-native wiki and markdown): fossil.page.addEventListener( 'wiki-preview-updated', (ev)=>{ if(ev.detail.mimetype!=='text/plain'){ ev.detail.element.querySelectorAll( 'code[class^=language-]' ).forEach((e)=>hljs.highlightBlock(e)); } } ); */ const E = (s)=>document.querySelector(s), D = F.dom, P = F.page; P.config = { /* Max number of locally-edited pages to stash, after which we drop the least-recently used. */ defaultMaxStashSize: 10, useConfirmerButtons:{ /* If true during fossil.page setup, certain buttons will use a "confirmer" step, else they will not.

All "stashed" state is stored using fossil.storage. - When the current wiki content is modified by the user, the current state of the page is stashed. - When saving, the stashed entry for the previous version is removed from the stash. - When "loading", we use any stashed state for the given checkin/file combination. When forcing a re-load of content, any stashed entry for that combination is removed from the stash. - Every time P.stashContentChange() updates the stash, it is pruned to $stash.prune.defaultMaxCount most-recently-updated entries. - This API often refers to "winfo objects." Those are objects with a minimum of {page,mimetype} properties (which must be valid), and the page name is used as basis for the stash keys for any given page. The structure of the stash is a bit convoluted for efficiency's sake: we store a map of file info (winfo) objects separately from those files' contents because otherwise we would be required to JSONize/de-JSONize the file content when stashing/restoring it, and that would be horribly inefficient (meaning "battery-consuming" on mobile devices). */ const $stash = { keys: { index: F.page.name+'.index' }, /** index: { "PAGE_NAME": {wiki page info w/o content} ... } In F.storage we... - Store this.index under the key this.keys.index. - Store each page's content under the key (P.name+'/PAGE_NAME').

(NN) ** "circleNodes": BOOLEAN, // True for circle nodes. False for squares ** "showArrowheads": BOOLEAN, // True for arrowheads. False to omit ** "iRailPitch": INTEGER, // Spacing between vertical lines (px) ** "colorGraph": BOOLEAN, // True to put color on graph lines ** "nomo": BOOLEAN, // True to join merge lines with rails ** "iTopRow": INTEGER, // Index of top-most row in the graph ** "omitDescenders": BOOLEAN, // Omit ancestor lines off bottom of screen ** "fileDiff": BOOLEAN, // True for file diff. False for check-in ** "scrollToSelect": BOOLEAN, // Scroll to selection on first render ** "nrail": INTEGER, // Number of vertical "rails" ** "baseUrl": TEXT, // Top-level URL ** "dwellTimeout": INTEGER, // Tooltip show delay in milliseconds ** "closeTimeout": INTEGER, // Tooltip close delay in milliseconds ** "hashDigits": INTEGER, // Limit of tooltip hashes ("hash-digits") ** "rowinfo": ROWINFO-ARRAY } ** ** The rowinfo field is an array of structures, one per entry in the timeline, ** where each structure has the following fields: ** ** id: The id of the <div> element for the row. This is an integer. ** to get an actual id, prepend "m" to the integer. The top node ** is iTopRow and numbers increase moving down the timeline. ** bg: The background color for this row ** r: The "rail" that the node for this row sits on. The left-most ** rail is 0 and the number increases to the right. ** d: If exists and true then there is a "descender" - an arrow ** coming from the bottom of the page straight up to this node. ** mo: "merge-out".

If there ** are no risers, this array does not exist. ** mi: "merge-in". An array of integer rail positions from which ** merge arrows should be drawn into this node.

The .c files contain “<code>#include</code>” preprocessor statements that cause the contents of .h files to be included as part of the source code when the .c file is compiled. In this way, the .h files define the interface to a subsystem and the .c files define how the subsystem is implemented. </p> <a name="H0003"></a> |

When the makeheaders program is run, it scans the source files for a project, then generates a series of new .h files, one for each .c file. The generated .h files contain exactly those declarations required by the corresponding .c files, no more and no less. |

Unfortunately, it is not possible to get makeheaders to process any file whose name contains a colon. </p> <p> In a large project, the length of the command line for makeheaders can become very long. If the operating system doesn't support long command lines (example: DOS and Win32) you may not be able to list all of the input files in the space available. In that case, you can use the “<code>-f</code>” option followed by the name of a file to cause makeheaders to read command line options and filename from the file instead of from the command line. For example, you might prepare a file named “<code>mkhdr.dat</code>” that contains text like this: <pre> src/alpha.c:hdr/alpha.h src/beta.c:hdr/beta.h src/gamma.c:hdr/gamma.h ... </pre> Then invoke makeheaders as follows: <pre> makeheaders -f mkhdr.dat </pre> </p> <p> The “<code>-local</code>” option causes makeheaders to generate of prototypes for “<code>static</code>” functions and procedures. Such prototypes are normally omitted. </p> <p> Finally, makeheaders also includes a “<code>-doc</code>” option. This command line option prevents makeheaders from generating any headers at all. Instead, makeheaders will write to standard output information about every definition and declaration that it encounters in its scan of source files. The information output includes the type of the definition or declaration and any comment that precedes the definition or declaration. The output is in a format that can be easily parsed, and is intended to be read by another program that will generate documentation about the program. We'll talk more about this feature later. </p> <p> If you forget what command line options are available, or forget their exact name, you can invoke makeheaders using an unknown command line option (like “<code>--help</code>” or “<code>-?</code>”) and it will print a summary of the available options on standard error. If you need to process a file whose name begins with “<code>-</code>”, you can prepend a “<code>./</code>” to its name in order to get it accepted by the command line parser. Or, you can insert the special option “<code>--</code>” on the command line to cause all subsequent command line arguments to be treated as filenames even if their names begin with “<code>-</code>”. </p> <a name="H0006"></a> <h2>3.0 Preparing Source Files For Use With Makeheaders</h2> <p> Very little has to be done to prepare source files for use with makeheaders since makeheaders will read and understand ordinary C code. But it is important that you structure your files in a way that makes sense in the makeheaders context. This section will describe several typical uses of makeheaders. </p> <a name="H0007"></a> <h3>3.1 The Basic Setup</h3> <p> The simplest way to use makeheaders is to put all definitions in one or more .c files and all structure and type declarations in separate .h files. The only restriction is that you should take care to chose basenames for your .h files that are different from the basenames for your .c files. Recall that if your .c file is named (for example) “<code>alpha.c</code>” makeheaders will attempt to generate a corresponding header file named “<code>alpha.h</code>”. For that reason, you don't want to use that name for any of the .h files you write since that will prevent makeheaders from generating the .h file automatically. </p> <p> The structure of a .c file intended for use with makeheaders is very simple. All you have to do is add a single “<code>#include</code>” to the top of the file that sources the header file that makeheaders will generate. Hence, the beginning of a source file named “<code>alpha.c</code>” might look something like this: </p> <pre> /* * Introductory comment... */ #include "alpha.h" /* The rest of your code... */ </pre> <p> Your manually generated header files require no special attention at all. Code them as you normally would. However, makeheaders will work better if you omit the “<code>#if</code>” statements people often put around the outside of header files that prevent the files from being included more than once. For example, to create a header file named “<code>beta.h</code>”, many people will habitually write the following: <pre> #ifndef BETA_H #define BETA_H /* declarations for beta.h go here */ #endif </pre> You can forego this cleverness with makeheaders. Remember that the header files you write will never really be included by any C code. Instead, makeheaders will scan your header files to extract only those declarations that are needed by individual .c files and then copy those declarations to the .h files corresponding to the .c files. Hence, the “<code>#if</code>” wrapper serves no useful purpose. But it does make makeheaders work harder, forcing it to put the statements <pre> #if !defined(BETA_H) #endif </pre> |

But that is not a problem. The makeheaders program will recognize and ignore any files it has previously generated that show up on its input list. </p> <a name="H0008"></a> <h3>3.2 What Declarations Get Copied</h3> <p> The following list details all of the code constructs that makeheaders will extract and place in the automatically generated .h files: </p> <ul> <p><li> When a function is defined in any .c file, a prototype of that function is placed in the generated .h file of every .c file that calls the function.</p> <P>If the “<code>static</code>” keyword of C appears at the beginning of the function definition, the prototype is suppressed. If you use the “<code>LOCAL</code>” keyword where you would normally say “<code>static</code>”, then a prototype is generated, but it will only appear in the single header file that corresponds to the source file containing the function. For example, if the file <code>alpha.c</code> contains the following: <pre> LOCAL int testFunc(void){ return 0; } </pre> Then the header file <code>alpha.h</code> will contain <pre> #define LOCAL static LOCAL int testFunc(void); </pre> However, no other generated header files will contain a prototype for <code>testFunc()</code> since the function has only file scope.</p> <p>When the “<code>LOCAL</code>” keyword is used, makeheaders will also generate a #define for LOCAL, like this: <pre> #define LOCAL static </pre> so that the C compiler will know what it means.</p> <p>If you invoke makeheaders with a “<code>-local</code>” command-line option, then it treats the “<code>static</code>” keyword like “<code>LOCAL</code>” and generates prototypes in the header file that corresponds to the source file containing the function definition.</p> <p><li> When a global variable is defined in a .c file, an “<code>extern</code>” declaration of that variable is placed in the header of every .c file that uses the variable. </p> <p><li> When a structure, union or enumeration declaration or a function prototype or a C++ class declaration appears in a manually produced .h file, that declaration is copied into the automatically generated .h files of all .c files that use the structure, union, enumeration, function or class. But declarations that appear in a .c file are considered private to that .c file and are not copied into any automatically generated files. </p> <p><li> All #defines and typedefs that appear in manually produced .h files are copied into automatically generated .h files as needed. Similar constructs that appear in .c files are considered private to those files and are not copied. </p> <p><li> When a structure, union or enumeration declaration appears in a .h file, makeheaders will automatically generate a typedef that allows the declaration to be referenced without the “<code>struct</code>”, “<code>union</code>” or “<code>enum</code>” qualifier. In other words, if makeheaders sees the code: <pre> struct Examp { /* ... */ }; </pre> it will automatically generate a corresponding typedef like this: <pre> typedef struct Examp Examp; </pre> </p> <p><li> Makeheaders generates an error message if it encounters a function or variable definition within a .h file. The .h files are suppose to contain only interface, not implementation. C compilers will not enforce this convention, but makeheaders does. </ul> <p> As a final note, we observe that automatically generated declarations are ordered as required by the ANSI-C programming language. If the declaration of some structure “<code>X</code>” requires a prior declaration of another structure “<code>Y</code>”, then Y will appear first in the generated headers. </p> <a name="H0009"></a> <h3>3.3 How To Avoid Having To Write Any Header Files</h3> <p> In my experience, large projects work better if all of the manually written code is placed in .c files and all .h files are generated automatically. This is slightly different from the traditional C method of placing the interface in .h files and the implementation in .c files, but it is a refreshing change that brings a noticeable improvement to the coding experience. Others, I believe, share this view since I've noticed recent languages (ex: java, tcl, perl, awk) tend to support the one-file approach to coding as the only option. </p> <p> |

608 609 610 611 612 613 614 | <p> You can instruct makeheaders to treat any part of a .c file as if it were a .h file by enclosing that part of the .c file within: <pre> #if INTERFACE #endif </pre> | | | | | | | | 615 616 617 618 619 620 621 622 623 624 625 626 627 628 629 630 631 632 633 634 635 636 637 638 639 640 641 642 643 644 645 646 647 648 649 650 651 652 653 654 655 656 657 658 659 660 | <p> You can instruct makeheaders to treat any part of a .c file as if it were a .h file by enclosing that part of the .c file within: <pre> #if INTERFACE #endif </pre> Thus any structure definitions that appear after the “<code>#if INTERFACE</code>” but before the corresponding “<code>#endif</code>” are eligible to be copied into the automatically generated .h files of other .c files. </p> <p> If you use the “<code>#if INTERFACE</code>” mechanism in a .c file, then the generated header for that .c file will contain a line like this: <pre> #define INTERFACE 0 </pre> In other words, the C compiler will never see any of the text that defines the interface. But makeheaders will copy all necessary definitions and declarations into the .h file it generates, so .c files will compile as if the declarations were really there. This approach has the advantage that you don't have to worry with putting the declarations in the correct ANSI-C order -- makeheaders will do that for you automatically. </p> <p> Note that you don't have to use this approach exclusively. You can put some declarations in .h files and others within the “<code>#if INTERFACE</code>” regions of .c files. Makeheaders treats all declarations alike, no matter where they come from. You should also note that a single .c file can contain as many “<code>#if INTERFACE</code>” regions as desired. </p> <a name="H0010"></a> <h3>3.4 Designating Declarations For Export</h3> <p> In a large project, one will often construct a hierarchy of |

Ordinary C does not provide support for a tiered interface like this, but makeheaders does. </p> <p> Using makeheaders, it is possible to designate routines and data structures as being for “<code>export</code>”. Exported objects are visible not only to other files within the same library or subassembly but also to other libraries and subassemblies in the larger program. By default, makeheaders only makes objects visible to other members of the same library. </p> <p> That isn't the complete truth, actually. The semantics of C are such that once an object becomes visible outside of a single source file, it is also visible to any user of the library that is made from the source file. Makeheaders can not prevent outsiders from using non-exported resources, but it can discourage the practice by refusing to provide prototypes and declarations for the services it does not want to export. Thus the only real effect of the making an object exportable is to include it in the output makeheaders generates when it is run using the -H command line option. This is not a perfect solution, but it works well in practice. </p> <p> But trouble quickly arises when we attempt to devise a mechanism for telling makeheaders which prototypes it should export and which it should keep local. The built-in “<code>static</code>” keyword of C works well for prohibiting prototypes from leaving a single source file, but because C doesn't support a linkage hierarchy, there is nothing in the C language to help us. We'll have to invite our own keyword: “<code>EXPORT</code>” </p> <p> Makeheaders allows the EXPORT keyword to precede any function or procedure definition. The routine following the EXPORT keyword is then eligable to appear in the header file generated using the -H command line option. |

The “<code>#if EXPORT_INTERFACE</code>” mechanism can be used in either .c or .h files. (The “<code>#if INTERFACE</code>” can also be used in both .h and .c files, but since it's use in a .h file would be redundant, we haven't mentioned it before.) </p> <a name="H0011"></a> <h3>3.5 Local declarations processed by makeheaders</h3> <p> Structure declarations and typedefs that appear in .c files are normally ignored by makeheaders. Such declarations are only intended for use by the source file in which they appear and so makeheaders doesn't need to copy them into any generated header files. We call such declarations “<code>private</code>”. </p> <p> Sometimes it is convenient to have makeheaders sort a sequence of private declarations into the correct order for us automatically. Or, we could have static functions and procedures for which we would like makeheaders to generate prototypes, but the arguments to these functions and procedures uses private declarations. In both of these cases, we want makeheaders to be aware of the private declarations and copy them into the local header file, but we don't want makeheaders to propagate the declarations outside of the file in which they are declared. </p> <p> When this situation arises, enclose the private declarations within <pre> #if LOCAL_INTERFACE #endif </pre> A “<code>LOCAL_INTERFACE</code>” block works very much like the “<code>INTERFACE</code>” and “<code>EXPORT_INTERFACE</code>” blocks described above, except that makeheaders insures that the objects declared in a LOCAL_INTERFACE are only visible to the file containing the LOCAL_INTERFACE. </p> <a name="H0012"></a> <h3>3.6 Using Makeheaders With C++ Code</h3> <p> You can use makeheaders to generate header files for C++ code, in addition to C. Makeheaders will recognize and copy both “<code>class</code>” declarations and inline function definitions, and it knows not to try to generate prototypes for methods. </p> <p> In fact, makeheaders is smart enough to be used in projects that employ a mixture of C and C++. |

If a method definition begins with one of the special keywords <b>PUBLIC</b>, <b>PROTECTED</b>, or <b>PRIVATE</b> (in upper-case to distinguish them from the regular C++ keywords with the same meaning) then a prototype for that method will be inserted into the class definition. If none of these keywords appear, then the prototype is not inserted.

In particular, it does not realize the significance of enumerated values, so the enum is not emitted in the header files when its enumerated values are used unless the name associated with the enum is also used. Moreover, enums can be completely anonymous, e.g. “<code>enum {X, Y, Z};</code>”. Makeheaders ignores such enums so they can at least be used within a single source file. Makeheaders expects you to use #define constants instead. If you want enum features that #define lacks, and you need the enum in the interface, bypass makeheaders and write a header file by hand, or teach makeheaders to emit the enum definition when any of the enumerated values are used, rather than only when the top-level name (if any) is used. </p> <a name="H0015"></a> <h2>4.0 Using Makeheaders To Generate Documentation</h2> <p> Many people have observed the advantages of generating program documentation directly from the source code: <ul> <li> Less effort is involved.

When documentation is derived directly from the code, or is contained in comments immediately adjacent to the code, it is much more likely to be correct than if it is contained in a separate unrelated file in a different part of the source tree. <li> Information is kept in only one place. When a change occurs in the code, it is not necessary to make a corresponding change in a separate document. Just rerun the documentation generator. </ul> The makeheaders program does not generate program documentation itself. But you can use makeheaders to parse the program source code, extract the information that is relevant to the documentation and to pass this information to another tool to do the actual documentation preparation. </p> <p> When makeheaders is run with the “<code>-doc</code>” option, it emits no header files at all. Instead, it does a complete dump of its internal tables to standard output in a form that is easily parsed. This output can then be used by another program (the implementation of which is left as an exercise to the reader) that will use the information to prepare suitable documentation. </p> <p> The “<code>-doc</code>” option causes makeheaders to print information to standard output about all of the following objects: <ul> <li> C++ class declarations <li> Structure and union declarations <li> Enumerations <li> Typedefs <li> Procedure and function definitions <li> Global variables <li> Preprocessor macros (ex: “<code>#define</code>”) </ul> For each of these objects, the following information is output: <ul> <li> The name of the object. <li> The type of the object. (Structure, typedef, macro, etc.) <li> Flags to indicate if the declaration is exported (contained within an EXPORT_INTERFACE block) or local (contained with LOCAL_INTERFACE). <li> A flag to indicate if the object is declared in a C++ file. <li> The name of the file in which the object was declared. <li> The complete text of any block comment that precedes the declarations. <li> If the declaration occurred inside a preprocessor conditional (“<code>#if</code>”) then the text of that conditional is provided. <li> The complete text of a declaration for the object. </ul> The exact output format will not be described here. It is simple to understand and parse and should be obvious to anyone who inspects some sample output. </p> <a name="H0016"></a> <h2>5.0 Compiling The Makeheaders Program</h2> <p> The source code for makeheaders is a single file of ANSI-C code, approximately 3000 lines in length. The program makes only modest demands of the system and C library and should compile without alteration on most ANSI C compilers and on most operating systems. It is known to compile using several variations of GCC for Unix as well as Cygwin32 and MSVC 5.0 for Win32. </p> <a name="H0017"></a> <h2>6.0 History</h2> <p> The makeheaders program was first written by D. Richard Hipp (also the original author of <a href="https://sqlite.org/">SQLite</a> and <a href="https://www.fossil-scm.org/">Fossil</a>) in 1993. Hipp open-sourced the project immediately, but it never caught on with any other developers and it continued to be used mostly by Hipp himself for over a decade. When Hipp was first writing the Fossil version control system in 2006 and 2007, he used makeheaders on that project to help simplify the source code. As the popularity of Fossil increased, the makeheaders that was incorporated into the Fossil source tree became the "official" makeheaders implementation. </p> <p> As this paragraph is being composed (2016-11-05), Fossil is the only project known to Hipp that is still using makeheaders. On the other hand, makeheaders has served the Fossil project well and there are no plans remove it. </p> <a name="H0018"></a> <h2>7.0 Summary And Conclusion</h2> <p> The makeheaders program will automatically generate a minimal header file for each of a set of C source and header files, and will generate a composite header file for the entire source file suite, for either internal or external use. It can also be used as the parser in an automated program documentation system. </p> <p> The makeheaders program has been in use since 1994, in a wide variety of projects under both UNIX and Win32. In every project where it has been used, makeheaders has proven to be a very helpful aid in the construction and maintenance of large C codes. In at least two cases, makeheaders has facilitated development of programs that would have otherwise been all but impossible due to their size and complexity. </p> </body> </html> |

reading/writing/appending, PNG writing See "unlicense" statement at the end of this file. Rich Geldreich <richgel99@gmail.com>, last updated Oct. 13, 2013 Implements RFC 1950: http://www.ietf.org/rfc/rfc1950.txt and RFC 1951: http://www.ietf.org/rfc/rfc1951.txt Most API's defined in miniz.c are optional. For example, to disable the archive related functions just define MINIZ_NO_ARCHIVE_APIS, or to get rid of all stdio usage define MINIZ_NO_STDIO (see the list below for more macros). * Change History 10/13/13 v1.15 r4 - Interim bugfix release while I work on the next major release with Zip64 support (almost there!): - Critical fix for the MZ_ZIP_FLAG_DO_NOT_SORT_CENTRAL_DIRECTORY bug (thanks kahmyong.moon@hp.com) which could cause locate files to not find files. This bug would only have occured in earlier versions if you explicitly used this flag, OR if you used mz_zip_extract_archive_file_to_heap() or mz_zip_add_mem_to_archive_file_in_place() (which used this flag). If you can't switch to v1.15 but want to fix this bug, just remove the uses of this flag from both helper funcs (and of course don't use the flag). - Bugfix in mz_zip_reader_extract_to_mem_no_alloc() from kymoon when pUser_read_buf is not NULL and compressed size is > uncompressed size - Fixing mz_zip_reader_extract_*() funcs so they don't try to extract compressed data from directory entries, to account for weird zipfiles which contain zero-size compressed data on dir entries. Hopefully this fix won't cause any issues on weird zip archives, because it assumes the low 16-bits of zip external attributes are DOS attributes (which I believe they always are in practice). - Fixing mz_zip_reader_is_file_a_directory() so it doesn't check the internal attributes, just the filename and external attributes - mz_zip_reader_init_file() - missing MZ_FCLOSE() call if the seek failed - Added cmake support for Linux builds which builds all the examples, tested with clang v3.3 and gcc v4.6. - Clang fix for tdefl_write_image_to_png_file_in_memory() from toffaletti - Merged MZ_FORCEINLINE fix from hdeanclark - Fix <time.h> include before config #ifdef, thanks emil.brink - Added tdefl_write_image_to_png_file_in_memory_ex(): supports Y flipping (super useful for OpenGL apps), and explicit control over the compression level (so you can set it to 1 for real-time compression). - Merged in some compiler fixes from paulharris's github repro. - Retested this build under Windows (VS 2010, including static analysis), tcc 0.9.26, gcc v4.6 and clang v3.3. - Added example6.c, which dumps an image of the mandelbrot set to a PNG file. - Modified example2 to help test the MZ_ZIP_FLAG_DO_NOT_SORT_CENTRAL_DIRECTORY flag more. - In r3: Bugfix to mz_zip_writer_add_file() found during merge: Fix possible src file fclose() leak if alignment bytes+local header file write faiiled - In r4: Minor bugfix to mz_zip_writer_add_from_zip_reader(): Was pushing the wrong central dir header offset, appears harmless in this release, but it became a problem in the zip64 branch 5/20/12 v1.14 - MinGW32/64 GCC 4.6.1 compiler fixes: added MZ_FORCEINLINE, #include <time.h> (thanks fermtect). 5/19/12 v1.13 - From jason@cornsyrup.org and kelwert@mtu.edu - Fix mz_crc32() so it doesn't compute the wrong CRC-32's when mz_ulong is 64-bit. - Temporarily/locally slammed in "typedef unsigned long mz_ulong" and re-ran a randomized regression test on ~500k files. - Eliminated a bunch of warnings when compiling with GCC 32-bit/64. - Ran all examples, miniz.c, and tinfl.c through MSVC 2008's /analyze (static analysis) option and fixed all warnings (except for the silly "Use of the comma-operator in a tested expression.." analysis warning, which I purposely use to work around a MSVC compiler warning). - Created 32-bit and 64-bit Codeblocks projects/workspace. Built and tested Linux executables. The codeblocks workspace is compatible with Linux+Win32/x64. - Added miniz_tester solution/project, which is a useful little app derived from LZHAM's tester app that I use as part of the regression test. - Ran miniz.c and tinfl.c through another series of regression testing on ~500,000 files and archives. - Modified example5.c so it purposely disables a bunch of high-level functionality (MINIZ_NO_STDIO, etc.). (Thanks to corysama for the MINIZ_NO_STDIO bug report.) - Fix ftell() usage in examples so they exit with an error on files which are too large (a limitation of the examples, not miniz itself). 4/12/12 v1.12 - More comments, added low-level example5.c, fixed a couple minor level_and_flags issues in the archive API's. level_and_flags can now be set to MZ_DEFAULT_COMPRESSION. Thanks to Bruce Dawson <bruced@valvesoftware.com> for the feedback/bug report. 5/28/11 v1.11 - Added statement from unlicense.org 5/27/11 v1.10 - Substantial compressor optimizations: - Level 1 is now ~4x faster than before. The L1 compressor's throughput now varies between 70-110MB/sec. on a - Core i7 (actual throughput varies depending on the type of data, and x64 vs. x86). - Improved baseline L2-L9 compression perf. Also, greatly improved compression perf. issues on some file types. - Refactored the compression code for better readability and maintainability. - Added level 10 compression level (L10 has slightly better ratio than level 9, but could have a potentially large drop in throughput on some files). 5/15/11 v1.09 - Initial stable release. * Low-level Deflate/Inflate implementation notes: Compression: Use the "tdefl" API's. The compressor supports raw, static, and dynamic blocks, lazy or greedy parsing, match length filtering, RLE-only, and Huffman-only streams. It performs and compresses approximately as well as zlib. Decompression: Use the "tinfl" API's. The entire decompressor is implemented as a single function coroutine: see tinfl_decompress(). It supports decompression into a 32KB (or larger power of 2) wrapping buffer, or into a memory block large enough to hold the entire file. The low-level tdefl/tinfl API's do not make any use of dynamic memory allocation. * zlib-style API notes: miniz.c implements a fairly large subset of zlib. There's enough functionality present for it to be a drop-in zlib replacement in many apps: The z_stream struct, optional memory allocation callbacks deflateInit/deflateInit2/deflate/deflateReset/deflateEnd/deflateBound inflateInit/inflateInit2/inflate/inflateEnd compress, compress2, compressBound, uncompress CRC-32, Adler-32 - Using modern, minimal code size, CPU cache friendly routines. Supports raw deflate streams or standard zlib streams with adler-32 checking. Limitations: The callback API's are not implemented yet. No support for gzip headers or zlib static dictionaries. I've tried to closely emulate zlib's various flavors of stream flushing and return status codes, but there are no guarantees that miniz.c pulls this off perfectly. * PNG writing: See the tdefl_write_image_to_png_file_in_memory() function, originally written by Alex Evans. Supports 1-4 bytes/pixel images. * ZIP archive API notes: The ZIP archive API's where designed with simplicity and efficiency in mind, with just enough abstraction to get the job done with minimal fuss. There are simple API's to retrieve file information, read files from existing archives, create new archives, append new files to existing archives, or clone archive data from one archive to another. It supports archives located in memory or the heap, on disk (using stdio.h), or you can specify custom file read/write callbacks. - Archive reading: Just call this function to read a single file from a disk archive: void *mz_zip_extract_archive_file_to_heap(const char *pZip_filename, const char *pArchive_name, size_t *pSize, mz_uint zip_flags); For more complex cases, use the "mz_zip_reader" functions. Upon opening an archive, the entire central directory is located and read as-is into memory, and subsequent file access only occurs when reading individual files. - Archives file scanning: The simple way is to use this function to scan a loaded archive for a specific file: int mz_zip_reader_locate_file(mz_zip_archive *pZip, const char *pName, const char *pComment, mz_uint flags); The locate operation can optionally check file comments too, which (as one example) can be used to identify multiple versions of the same file in an archive. This function uses a simple linear search through the central directory, so it's not very fast. Alternately, you can iterate through all the files in an archive (using mz_zip_reader_get_num_files()) and retrieve detailed info on each file by calling mz_zip_reader_file_stat(). - Archive creation: Use the "mz_zip_writer" functions. The ZIP writer immediately writes compressed file data to disk and builds an exact image of the central directory in memory. The central directory image is written all at once at the end of the archive file when the archive is finalized. The archive writer can optionally align each file's local header and file data to any power of 2 alignment, which can be useful when the archive will be read from optical media. Also, the writer supports placing arbitrary data blobs at the very beginning of ZIP archives. Archives written using either feature are still readable by any ZIP tool. - Archive appending: The simple way to add a single file to an archive is to call this function: mz_bool mz_zip_add_mem_to_archive_file_in_place(const char *pZip_filename, const char *pArchive_name, const void *pBuf, size_t buf_size, const void *pComment, mz_uint16 comment_size, mz_uint level_and_flags); The archive will be created if it doesn't already exist, otherwise it'll be appended to. Note the appending is done in-place and is not an atomic operation, so if something goes wrong during the operation it's possible the archive could be left without a central directory (although the local file headers and file data will be fine, so the archive will be recoverable). For more complex archive modification scenarios: 1. The safest way is to use a mz_zip_reader to read the existing archive, cloning only those bits you want to preserve into a new archive using using the mz_zip_writer_add_from_zip_reader() function (which compiles the compressed file data as-is). When you're done, delete the old archive and rename the newly written archive, and you're done. This is safe but requires a bunch of temporary disk space or heap memory. 2. Or, you can convert an mz_zip_reader in-place to an mz_zip_writer using mz_zip_writer_init_from_reader(), append new files as needed, then finalize the archive which will write an updated central directory to the original archive. (This is basically what mz_zip_add_mem_to_archive_file_in_place() does.) There's a possibility that the archive's central directory could be lost with this method if anything goes wrong, though. - ZIP archive support limitations: No zip64 or spanning support. Extraction functions can only handle unencrypted, stored or deflated files. Requires streams capable of seeking. * This is a header file library, like stb_image.c.

If a captcha string consists of just hexadecimal digits (as is the case for captchas generated by the [../captcha.c module](../captcha.c)) then these WAV files can be concatenated together to generate an audio reading of the captcha, which enables visually impaired users to complete the captcha. Each of the WAV files uses 8000 samples per second, 8 bytes per sample and are 6000 samples in length. The recordings are made by Philip Bennefall and are of his own voice. Mr. Bennefall is himself blind and uses this system implemented with these recordings to complete captchas for Fossil. |

This capability ** is used during testing and is only available when the SQLITE_TEST ** compile-time option is used. ** ** <li>[[SQLITE_FCNTL_SIZE_HINT]] ** The [SQLITE_FCNTL_SIZE_HINT] opcode is used by SQLite to give the VFS ** layer a hint of how large the database file will grow to be during the ** current transaction. This hint is not guaranteed to be accurate but it ** is often close. The underlying VFS might choose to preallocate database ** file space based on this hint in order to help writes to the database ** file run faster. ** ** <li>[[SQLITE_FCNTL_SIZE_LIMIT]] ** The [SQLITE_FCNTL_SIZE_LIMIT] opcode is used by in-memory VFS that ** implements [sqlite3_deserialize()] to set an upper bound on the size ** of the in-memory database. The argument is a pointer to a [sqlite3_int64]. ** If the integer pointed to is negative, then it is filled in with the ** current limit. Otherwise the limit is set to the larger of the value ** of the integer pointed to and the current database size. The integer ** pointed to is set to the new limit. ** ** <li>[[SQLITE_FCNTL_CHUNK_SIZE]] ** The [SQLITE_FCNTL_CHUNK_SIZE] opcode is used to request that the VFS ** extends and truncates the database file in chunks of a size specified ** by the user. The fourth argument to [sqlite3_file_control()] should ** point to an integer (type int) containing the new chunk-size to use ** for the nominated database. Allocating database file space in large ** chunks (say 1MB at a time), may reduce file-system fragmentation and ** improve performance on some systems. ** ** <li>[[SQLITE_FCNTL_FILE_POINTER]] ** The [SQLITE_FCNTL_FILE_POINTER] opcode is used to obtain a pointer ** to the [sqlite3_file] object associated with a particular database ** connection.

Or, if the xSync method is not invoked ** because the user has configured SQLite with ** [PRAGMA synchronous | PRAGMA synchronous=OFF] it is invoked in place ** of the xSync method. In most cases, the pointer argument passed with ** this file-control is NULL. However, if the database file is being synced ** as part of a multi-database commit, the argument points to a nul-terminated ** string containing the transactions super-journal file name.

Applications ** should not call [sqlite3_file_control()] with this opcode as doing so may ** disrupt the operation of the specialized VFSes that do require it. ** ** <li>[[SQLITE_FCNTL_COMMIT_PHASETWO]] ** The [SQLITE_FCNTL_COMMIT_PHASETWO] opcode is generated internally by SQLite ** and sent to the VFS after a transaction has been committed immediately ** but before the database is unlocked. VFSes that do not need this signal ** should silently ignore this opcode. Applications should not call ** [sqlite3_file_control()] with this opcode as doing so may disrupt the ** operation of the specialized VFSes that do require it. ** ** <li>[[SQLITE_FCNTL_WIN32_AV_RETRY]] ** ^The [SQLITE_FCNTL_WIN32_AV_RETRY] opcode is used to configure automatic ** retry counts and intervals for certain disk I/O operations for the ** windows [VFS] in order to provide robustness in the presence of ** anti-virus programs. By default, the windows VFS will retry file read, ** file write, and file delete operations up to 10 times, with a delay ** of 25 milliseconds before the first retry and with the delay increasing ** by an additional 25 milliseconds with each subsequent retry. This ** opcode allows these two values (10 retries and 25 milliseconds of delay) ** to be adjusted. The values are changed for all database connections ** within the same process. The argument is a pointer to an array of two ** integers where the first integer is the new retry count and the second ** integer is the delay. If either integer is negative, then the setting ** is not changed but instead the prior value of that setting is written ** into the array entry, allowing the current retry settings to be ** interrogated. The zDbName parameter is ignored. ** ** <li>[[SQLITE_FCNTL_PERSIST_WAL]] ** ^The [SQLITE_FCNTL_PERSIST_WAL] opcode is used to set or query the ** persistent [WAL | Write Ahead Log] setting. By default, the auxiliary ** write ahead log ([WAL file]) and shared memory ** files used for transaction control ** are automatically deleted when the latest connection to the database ** closes. Setting persistent WAL mode causes those files to persist after ** close. Persisting the files is useful when other processes that do not ** have write permission on the directory containing the database file want ** to read the database file, as the WAL and shared memory files must exist ** in order for the database to be readable. The fourth parameter to ** [sqlite3_file_control()] for this opcode should be a pointer to an integer. ** That integer is 0 to disable persistent WAL mode or 1 to enable persistent ** WAL mode. If the integer is -1, then it is overwritten with the current ** WAL persistence setting. ** ** <li>[[SQLITE_FCNTL_POWERSAFE_OVERWRITE]] ** ^The [SQLITE_FCNTL_POWERSAFE_OVERWRITE] opcode is used to set or query the ** persistent "powersafe-overwrite" or "PSOW" setting. The PSOW setting ** determines the [SQLITE_IOCAP_POWERSAFE_OVERWRITE] bit of the ** xDeviceCharacteristics methods. The fourth parameter to ** [sqlite3_file_control()] for this opcode should be a pointer to an integer. ** That integer is 0 to disable zero-damage mode or 1 to enable zero-damage ** mode. If the integer is -1, then it is overwritten with the current ** zero-damage mode setting. ** ** <li>[[SQLITE_FCNTL_OVERWRITE]] ** ^The [SQLITE_FCNTL_OVERWRITE] opcode is invoked by SQLite after opening ** a write transaction to indicate that, unless it is rolled back for some ** reason, the entire database file will be overwritten by the current ** transaction. This is used by VACUUM operations. ** ** <li>[[SQLITE_FCNTL_VFSNAME]] ** ^The [SQLITE_FCNTL_VFSNAME] opcode can be used to obtain the names of ** all [VFSes] in the VFS stack. The names are of all VFS shims and the ** final bottom-level VFS are written into memory obtained from ** [sqlite3_malloc()] and the result is stored in the char* variable ** that the fourth parameter of [sqlite3_file_control()] points to. ** The caller is responsible for freeing the memory when done. As with ** all file-control actions, there is no guarantee that this will actually ** do anything. Callers should initialize the char* variable to a NULL ** pointer in case this file-control is not implemented. This file-control ** is intended for diagnostic use only. ** ** <li>[[SQLITE_FCNTL_VFS_POINTER]] ** ^The [SQLITE_FCNTL_VFS_POINTER] opcode finds a pointer to the top-level ** [VFSes] currently in use. ^(The argument X in ** sqlite3_file_control(db,SQLITE_FCNTL_VFS_POINTER,X) must be ** of type "[sqlite3_vfs] **". This opcodes will set *X ** to a pointer to the top-level VFS.)^ ** ^When there are multiple VFS shims in the stack, this opcode finds the ** upper-most shim only. ** ** <li>[[SQLITE_FCNTL_PRAGMA]] ** ^Whenever a [PRAGMA] statement is parsed, an [SQLITE_FCNTL_PRAGMA] ** file control is sent to the open [sqlite3_file] object corresponding ** to the database file to which the pragma statement refers. ^The argument ** to the [SQLITE_FCNTL_PRAGMA] file control is an array of ** pointers to strings (char**) in which the second element of the array ** is the name of the pragma and the third element is the argument to the ** pragma or NULL if the pragma has no argument. ^The handler for an ** [SQLITE_FCNTL_PRAGMA] file control can optionally make the first element ** of the char** argument point to a string obtained from [sqlite3_mprintf()] ** or the equivalent and that string will become the result of the pragma or ** the error message if the pragma fails. ^If the ** [SQLITE_FCNTL_PRAGMA] file control returns [SQLITE_NOTFOUND], then normal ** [PRAGMA] processing continues. ^If the [SQLITE_FCNTL_PRAGMA] ** file control returns [SQLITE_OK], then the parser assumes that the ** VFS has handled the PRAGMA itself and the parser generates a no-op ** prepared statement if result string is NULL, or that returns a copy ** of the result string if the string is non-NULL. ** ^If the [SQLITE_FCNTL_PRAGMA] file control returns ** any result code other than [SQLITE_OK] or [SQLITE_NOTFOUND], that means ** that the VFS encountered an error while handling the [PRAGMA] and the ** compilation of the PRAGMA fails with an error. ^The [SQLITE_FCNTL_PRAGMA] ** file control occurs at the beginning of pragma statement analysis and so ** it is able to override built-in [PRAGMA] statements. ** ** <li>[[SQLITE_FCNTL_BUSYHANDLER]] ** ^The [SQLITE_FCNTL_BUSYHANDLER] ** file-control may be invoked by SQLite on the database file handle ** shortly after it is opened in order to provide a custom VFS with access ** to the connection's busy-handler callback. The argument is of type (void**) ** - an array of two (void *) values. The first (void *) actually points ** to a function of type (int (*)(void *)). In order to invoke the connection's ** busy-handler, this function should be invoked with the second (void *) in ** the array as the only argument. If it returns non-zero, then the operation ** should be retried. If it returns zero, the custom VFS should abandon the ** current operation. ** ** <li>[[SQLITE_FCNTL_TEMPFILENAME]] ** ^Applications can invoke the [SQLITE_FCNTL_TEMPFILENAME] file-control ** to have SQLite generate a ** temporary filename using the same algorithm that is followed to generate ** temporary filenames for TEMP tables and other internal uses. The ** argument should be a char** which will be filled with the filename ** written into memory obtained from [sqlite3_malloc()]. The caller should ** invoke [sqlite3_free()] on the result to avoid a memory leak. ** ** <li>[[SQLITE_FCNTL_MMAP_SIZE]] ** The [SQLITE_FCNTL_MMAP_SIZE] file control is used to query or set the ** maximum number of bytes that will be used for memory-mapped I/O. ** The argument is a pointer to a value of type sqlite3_int64 that ** is an advisory maximum number of bytes in the file to memory map. The ** pointer is overwritten with the old value. The limit is not changed if ** the value originally pointed to is negative, and so the current limit ** can be queried by passing in a pointer to a negative number. This ** file-control is used internally to implement [PRAGMA mmap_size]. ** ** <li>[[SQLITE_FCNTL_TRACE]] ** The [SQLITE_FCNTL_TRACE] file control provides advisory information ** to the VFS about what the higher layers of the SQLite stack are doing. ** This file control is used by some VFS activity tracing [shims]. ** The argument is a zero-terminated string. Higher layers in the ** SQLite stack may generate instances of this file control if ** the [SQLITE_USE_FCNTL_TRACE] compile-time option is enabled. ** ** <li>[[SQLITE_FCNTL_HAS_MOVED]] ** The [SQLITE_FCNTL_HAS_MOVED] file control interprets its argument as a ** pointer to an integer and it writes a boolean into that integer depending ** on whether or not the file has been renamed, moved, or deleted since it ** was first opened. ** ** <li>[[SQLITE_FCNTL_WIN32_GET_HANDLE]] ** The [SQLITE_FCNTL_WIN32_GET_HANDLE] opcode can be used to obtain the ** underlying native file handle associated with a file handle. This file ** control interprets its argument as a pointer to a native file handle and ** writes the resulting value there. ** ** <li>[[SQLITE_FCNTL_WIN32_SET_HANDLE]] ** The [SQLITE_FCNTL_WIN32_SET_HANDLE] opcode is used for debugging. This ** opcode causes the xFileControl method to swap the file handle with the one ** pointed to by the pArg argument. This capability is used during testing ** and only needs to be supported when SQLITE_TEST is defined. ** ** <li>[[SQLITE_FCNTL_WAL_BLOCK]] ** The [SQLITE_FCNTL_WAL_BLOCK] is a signal to the VFS layer that it might ** be advantageous to block on the next WAL lock if the lock is not immediately ** available. The WAL subsystem issues this signal during rare ** circumstances in order to fix a problem with priority inversion. ** Applications should <em>not</em> use this file-control. ** ** <li>[[SQLITE_FCNTL_ZIPVFS]] ** The [SQLITE_FCNTL_ZIPVFS] opcode is implemented by zipvfs only. All other ** VFS should return SQLITE_NOTFOUND for this opcode. ** ** <li>[[SQLITE_FCNTL_RBU]] ** The [SQLITE_FCNTL_RBU] opcode is implemented by the special VFS used by ** the RBU extension only. All other VFS should return SQLITE_NOTFOUND for ** this opcode. ** ** <li>[[SQLITE_FCNTL_BEGIN_ATOMIC_WRITE]] ** If the [SQLITE_FCNTL_BEGIN_ATOMIC_WRITE] opcode returns SQLITE_OK, then ** the file descriptor is placed in "batch write mode", which ** means all subsequent write operations will be deferred and done ** atomically at the next [SQLITE_FCNTL_COMMIT_ATOMIC_WRITE]. Systems ** that do not support batch atomic writes will return SQLITE_NOTFOUND. ** ^Following a successful SQLITE_FCNTL_BEGIN_ATOMIC_WRITE and prior to ** the closing [SQLITE_FCNTL_COMMIT_ATOMIC_WRITE] or ** [SQLITE_FCNTL_ROLLBACK_ATOMIC_WRITE], SQLite will make ** no VFS interface calls on the same [sqlite3_file] file descriptor ** except for calls to the xWrite method and the xFileControl method ** with [SQLITE_FCNTL_SIZE_HINT]. ** ** <li>[[SQLITE_FCNTL_COMMIT_ATOMIC_WRITE]] ** The [SQLITE_FCNTL_COMMIT_ATOMIC_WRITE] opcode causes all write ** operations since the previous successful call to ** [SQLITE_FCNTL_BEGIN_ATOMIC_WRITE] to be performed atomically. ** This file control returns [SQLITE_OK] if and only if the writes were ** all performed successfully and have been committed to persistent storage. ** ^Regardless of whether or not it is successful, this file control takes ** the file descriptor out of batch write mode so that all subsequent ** write operations are independent. ** ^SQLite will never invoke SQLITE_FCNTL_COMMIT_ATOMIC_WRITE without ** a prior successful call to [SQLITE_FCNTL_BEGIN_ATOMIC_WRITE]. ** ** <li>[[SQLITE_FCNTL_ROLLBACK_ATOMIC_WRITE]] ** The [SQLITE_FCNTL_ROLLBACK_ATOMIC_WRITE] opcode causes all write ** operations since the previous successful call to ** [SQLITE_FCNTL_BEGIN_ATOMIC_WRITE] to be rolled back. ** ^This file control takes the file descriptor out of batch write mode ** so that all subsequent write operations are independent. ** ^SQLite will never invoke SQLITE_FCNTL_ROLLBACK_ATOMIC_WRITE without ** a prior successful call to [SQLITE_FCNTL_BEGIN_ATOMIC_WRITE]. ** ** <li>[[SQLITE_FCNTL_LOCK_TIMEOUT]] ** The [SQLITE_FCNTL_LOCK_TIMEOUT] opcode is used to configure a VFS ** to block for up to M milliseconds before failing when attempting to ** obtain a file lock using the xLock or xShmLock methods of the VFS. ** The parameter is a pointer to a 32-bit signed integer that contains ** the value that M is to be set to. Before returning, the 32-bit signed ** integer is overwritten with the previous value of M. ** ** <li>[[SQLITE_FCNTL_DATA_VERSION]] ** The [SQLITE_FCNTL_DATA_VERSION] opcode is used to detect changes to ** a database file. The argument is a pointer to a 32-bit unsigned integer. ** The "data version" for the pager is written into the pointer. The ** "data version" changes whenever any change occurs to the corresponding ** database file, either through SQL statements on the same database ** connection or through transactions committed by separate database ** connections possibly in other processes. The [sqlite3_total_changes()] ** interface can be used to find if any database on the connection has changed, ** but that interface responds to changes on TEMP as well as MAIN and does ** not provide a mechanism to detect changes to MAIN only. Also, the ** [sqlite3_total_changes()] interface responds to internal changes only and ** omits changes made by other database connections. The ** [PRAGMA data_version] command provides a mechanism to detect changes to ** a single attached database that occur due to other database connections, ** but omits changes implemented by the database connection on which it is ** called. This file control is the only mechanism to detect changes that ** happen either internally or externally and that are associated with ** a particular attached database. ** ** <li>[[SQLITE_FCNTL_CKPT_START]] ** The [SQLITE_FCNTL_CKPT_START] opcode is invoked from within a checkpoint ** in wal mode before the client starts to copy pages from the wal ** file to the database file. ** ** <li>[[SQLITE_FCNTL_CKPT_DONE]] ** The [SQLITE_FCNTL_CKPT_DONE] opcode is invoked from within a checkpoint ** in wal mode after the client has finished copying pages from the wal ** file to the database file, but before the *-shm file is updated to ** record the fact that the pages have been checkpointed. ** </ul> */ #define SQLITE_FCNTL_LOCKSTATE 1 #define SQLITE_FCNTL_GET_LOCKPROXYFILE 2 #define SQLITE_FCNTL_SET_LOCKPROXYFILE 3 #define SQLITE_FCNTL_LAST_ERRNO 4 #define SQLITE_FCNTL_SIZE_HINT 5 #define SQLITE_FCNTL_CHUNK_SIZE 6 #define SQLITE_FCNTL_FILE_POINTER 7 #define SQLITE_FCNTL_SYNC_OMITTED 8 #define SQLITE_FCNTL_WIN32_AV_RETRY 9 #define SQLITE_FCNTL_PERSIST_WAL 10 #define SQLITE_FCNTL_OVERWRITE 11 #define SQLITE_FCNTL_VFSNAME 12 #define SQLITE_FCNTL_POWERSAFE_OVERWRITE 13 #define SQLITE_FCNTL_PRAGMA 14 #define SQLITE_FCNTL_BUSYHANDLER 15 #define SQLITE_FCNTL_TEMPFILENAME 16 #define SQLITE_FCNTL_MMAP_SIZE 18 #define SQLITE_FCNTL_TRACE 19 #define SQLITE_FCNTL_HAS_MOVED 20 #define SQLITE_FCNTL_SYNC 21 #define SQLITE_FCNTL_COMMIT_PHASETWO 22 #define SQLITE_FCNTL_WIN32_SET_HANDLE 23 #define SQLITE_FCNTL_WAL_BLOCK 24 #define SQLITE_FCNTL_ZIPVFS 25 #define SQLITE_FCNTL_RBU 26 #define SQLITE_FCNTL_VFS_POINTER 27 #define SQLITE_FCNTL_JOURNAL_POINTER 28 #define SQLITE_FCNTL_WIN32_GET_HANDLE 29 #define SQLITE_FCNTL_PDB 30 #define SQLITE_FCNTL_BEGIN_ATOMIC_WRITE 31 #define SQLITE_FCNTL_COMMIT_ATOMIC_WRITE 32 #define SQLITE_FCNTL_ROLLBACK_ATOMIC_WRITE 33 #define SQLITE_FCNTL_LOCK_TIMEOUT 34 #define SQLITE_FCNTL_DATA_VERSION 35 #define SQLITE_FCNTL_SIZE_LIMIT 36 #define SQLITE_FCNTL_CKPT_DONE 37 #define SQLITE_FCNTL_RESERVE_BYTES 38 #define SQLITE_FCNTL_CKPT_START 39 /* deprecated names */ #define SQLITE_GET_LOCKPROXYFILE SQLITE_FCNTL_GET_LOCKPROXYFILE #define SQLITE_SET_LOCKPROXYFILE SQLITE_FCNTL_SET_LOCKPROXYFILE #define SQLITE_LAST_ERRNO SQLITE_FCNTL_LAST_ERRNO /* ** CAPI3REF: Mutex Handle ** ** The mutex module within SQLite defines [sqlite3_mutex] to be an ** abstract type for a mutex object.

The SQLITE_OPEN_EXCLUSIVE flag, when paired with the ** SQLITE_OPEN_CREATE, is used to indicate that file should always ** be created, and that it is an error if it already exists. ** It is <i>not</i> used to indicate the file should be opened ** for exclusive access. ** ** ^At least szOsFile bytes of memory are allocated by SQLite ** to hold the [sqlite3_file] structure passed as the third ** argument to xOpen. The xOpen method does not have to ** allocate the structure; it should just fill it in. Note that ** the xOpen method must set the sqlite3_file.pMethods to either ** a valid [sqlite3_io_methods] object or to NULL. xOpen must do ** this even if the open fails. SQLite expects that the sqlite3_file.pMethods ** element will be valid after xOpen returns regardless of the success ** or failure of the xOpen call. ** ** [[sqlite3_vfs.xAccess]] ** ^The flags argument to xAccess() may be [SQLITE_ACCESS_EXISTS] ** to test for the existence of a file, or [SQLITE_ACCESS_READWRITE] to ** test whether a file is readable and writable, or [SQLITE_ACCESS_READ] ** to test whether a file is at least readable. The SQLITE_ACCESS_READ ** flag is never actually used and is not implemented in the built-in ** VFSes of SQLite. The file is named by the second argument and can be a ** directory. The xAccess method returns [SQLITE_OK] on success or some ** non-zero error code if there is an I/O error or if the name of ** the file given in the second argument is illegal. If SQLITE_OK ** is returned, then non-zero or zero is written into *pResOut to indicate ** whether or not the file is accessible. ** ** ^SQLite will always allocate at least mxPathname+1 bytes for the ** output buffer xFullPathname. The exact size of the output buffer ** is also passed as a parameter to both methods. If the output buffer ** is not large enough, [SQLITE_CANTOPEN] should be returned. Since this is ** handled as a fatal error by SQLite, vfs implementations should endeavor ** to prevent this by setting mxPathname to a sufficiently large value. ** ** The xRandomness(), xSleep(), xCurrentTime(), and xCurrentTimeInt64() ** interfaces are not strictly a part of the filesystem, but they are ** included in the VFS structure for completeness. ** The xRandomness() function attempts to return nBytes bytes ** of good-quality randomness into zOut. The return value is ** the actual number of bytes of randomness obtained. ** The xSleep() method causes the calling thread to sleep for at ** least the number of microseconds given. ^The xCurrentTime() ** method returns a Julian Day Number for the current date and time as ** a floating point value. ** ^The xCurrentTimeInt64() method returns, as an integer, the Julian ** Day Number multiplied by 86400000 (the number of milliseconds in ** a 24-hour day). ** ^SQLite will use the xCurrentTimeInt64() method to get the current ** date and time if that method is available (if iVersion is 2 or ** greater and the function pointer is not NULL) and will fall back ** to xCurrentTime() if xCurrentTimeInt64() is unavailable. ** ** ^The xSetSystemCall(), xGetSystemCall(), and xNestSystemCall() interfaces ** are not used by the SQLite core.

The sqlite3_bind_pointer() ** routine is part of the [pointer passing interface] added for SQLite 3.20.0. ** ** ^(The sqlite3_value_type(V) interface returns the ** [SQLITE_INTEGER | datatype code] for the initial datatype of the ** [sqlite3_value] object V. The returned value is one of [SQLITE_INTEGER], ** [SQLITE_FLOAT], [SQLITE_TEXT], [SQLITE_BLOB], or [SQLITE_NULL].)^ ** Other interfaces might change the datatype for an sqlite3_value object. ** For example, if the datatype is initially SQLITE_INTEGER and ** sqlite3_value_text(V) is called to extract a text value for that ** integer, then subsequent calls to sqlite3_value_type(V) might return ** SQLITE_TEXT. Whether or not a persistent internal datatype conversion ** occurs is undefined and may change from one release of SQLite to the next. ** ** ^(The sqlite3_value_numeric_type() interface attempts to apply ** numeric affinity to the value. This means that an attempt is ** made to convert the value to an integer or floating point.

If an error occurs, set both *ppChangeset and *pnChangeset to ** zero and return an SQLite error code. ** ** A changeset consists of zero or more INSERT, UPDATE and/or DELETE changes, ** each representing a change to a single row of an attached table. An INSERT ** change contains the values of each field of a new database row. A DELETE ** contains the original values of each field of a deleted database row. An ** UPDATE change contains the original values of each field of an updated ** database row along with the updated values for each updated non-primary-key ** column. It is not possible for an UPDATE change to represent a change that ** modifies the values of primary key columns.

Tables ** are sorted in the same order in which they were attached (or auto-attached) ** to the sqlite3_session object. The order in which the changes related to ** a single table are stored is undefined. ** ** Following a successful call to this function, it is the responsibility of ** the caller to eventually free the buffer that *ppChangeset points to using ** [sqlite3_free()]. ** ** <h3>Changeset Generation</h3> ** ** Once a table has been attached to a session object, the session object ** records the primary key values of all new rows inserted into the table. ** It also records the original primary key and other column values of any ** deleted or updated rows. For each unique primary key value, data is only ** recorded once - the first time a row with said primary key is inserted, ** updated or deleted in the lifetime of the session. ** ** There is one exception to the previous paragraph: when a row is inserted, ** updated or deleted, if one or more of its primary key columns contain a ** NULL value, no record of the change is made. ** ** The session object therefore accumulates two types of records - those ** that consist of primary key values only (created when the user inserts ** a new record) and those that consist of the primary key values and the ** original values of other table columns (created when the users deletes ** or updates a record). ** ** When this function is called, the requested changeset is created using ** both the accumulated records and the current contents of the database ** file. Specifically: ** ** <ul> ** <li> For each record generated by an insert, the database is queried ** for a row with a matching primary key. If one is found, an INSERT ** change is added to the changeset. If no such row is found, no change ** is added to the changeset. ** ** <li> For each record generated by an update or delete, the database is ** queried for a row with a matching primary key. If such a row is ** found and one or more of the non-primary key fields have been ** modified from their original values, an UPDATE change is added to ** the changeset. Or, if no such row is found in the table, a DELETE ** change is added to the changeset.

If the ** database table has more columns than are recorded in the changeset, ** only the values of those non-primary key fields are compared against ** the current database contents - any trailing database table columns ** are ignored. ** ** If no row with matching primary key values is found in the database, ** the conflict-handler function is invoked with [SQLITE_CHANGESET_NOTFOUND] ** passed as the second argument. ** ** If the DELETE operation is attempted, but SQLite returns SQLITE_CONSTRAINT ** (which can only happen if a foreign key constraint is violated), the ** conflict-handler function is invoked with [SQLITE_CHANGESET_CONSTRAINT] ** passed as the second argument. This includes the case where the DELETE ** operation is attempted because an earlier call to the conflict handler ** function returned [SQLITE_CHANGESET_REPLACE]. ** ** <dt>INSERT Changes<dd> ** For each INSERT change, an attempt is made to insert the new row into ** the database. If the changeset row contains fewer fields than the ** database table, the trailing fields are populated with their default ** values. ** ** If the attempt to insert the row fails because the database already ** contains a row with the same primary key values, the conflict handler ** function is invoked with the second argument set to ** [SQLITE_CHANGESET_CONFLICT]. ** ** If the attempt to insert the row fails because of some other constraint ** violation (e.g. NOT NULL or UNIQUE), the conflict handler function is ** invoked with the second argument set to [SQLITE_CHANGESET_CONSTRAINT]. ** This includes the case where the INSERT operation is re-attempted because ** an earlier call to the conflict handler function returned ** [SQLITE_CHANGESET_REPLACE]. ** ** <dt>UPDATE Changes<dd> ** For each UPDATE change, the function checks if the target database ** contains a row with the same primary key value (or values) as the ** original row values stored in the changeset.

Since ** UPDATE changes only contain values for non-primary key fields that are ** to be modified, only those fields need to match the original values to ** avoid the SQLITE_CHANGESET_DATA conflict-handler callback. ** ** If no row with matching primary key values is found in the database, ** the conflict-handler function is invoked with [SQLITE_CHANGESET_NOTFOUND] ** passed as the second argument. ** ** If the UPDATE operation is attempted, but SQLite returns ** SQLITE_CONSTRAINT, the conflict-handler function is invoked with ** [SQLITE_CHANGESET_CONSTRAINT] passed as the second argument. ** This includes the case where the UPDATE operation is attempted after ** an earlier call to the conflict handler function returned ** [SQLITE_CHANGESET_REPLACE]. ** </dl> ** ** It is safe to execute SQL statements, including those that write to the ** table that the callback related to, from within the xConflict callback. ** This can be used to further customize the application's conflict ** resolution strategy. ** ** All changes made by these functions are enclosed in a savepoint transaction. ** If any other error (aside from a constraint failure when attempting to ** write to the target database) occurs, then the savepoint transaction is ** rolled back, restoring the target database to its original state, and an ** SQLite error code returned. ** ** If the output parameters (ppRebase) and (pnRebase) are non-NULL and ** the input is a changeset (not a patchset), then sqlite3changeset_apply_v2() ** may set (*ppRebase) to point to a "rebase" that may be used with the ** sqlite3_rebaser APIs buffer before returning.

The context and API objects passed to the callback ** function may be used to access the properties of each matched row. ** Invoking Api.xUserData() returns a copy of the pointer passed as ** the third argument to pUserData. ** ** If the callback function returns any value other than SQLITE_OK, the ** query is abandoned and the xQueryPhrase function returns immediately. ** If the returned value is SQLITE_DONE, xQueryPhrase returns SQLITE_OK. ** Otherwise, the error code is propagated upwards. ** ** If the query runs to completion without incident, SQLITE_OK is returned. ** Or, if some error occurs before the query completes or is aborted by ** the callback, an SQLite error code is returned. ** ** ** xSetAuxdata(pFts5, pAux, xDelete) ** ** Save the pointer passed as the second argument as the extension function's ** "auxiliary data". The pointer may then be retrieved by the current or any ** future invocation of the same fts5 extension function made as part of ** the same MATCH query using the xGetAuxdata() API. ** ** Each extension function is allocated a single auxiliary data slot for ** each FTS query (MATCH expression). If the extension function is invoked ** more than once for a single FTS query, then all invocations share a ** single auxiliary data context. ** ** If there is already an auxiliary data pointer when this function is ** invoked, then it is replaced by the new pointer. If an xDelete callback ** was specified along with the original pointer, it is invoked at this ** point. ** ** The xDelete callback, if one is specified, is also invoked on the ** auxiliary data pointer after the FTS5 query has finished. ** ** If an error (e.g. an OOM condition) occurs within this function, ** the auxiliary data is set to NULL and an error code returned. If the ** xDelete parameter was not NULL, it is invoked on the auxiliary data ** pointer before returning. ** ** ** xGetAuxdata(pFts5, bClear) ** ** Returns the current auxiliary data pointer for the fts5 extension ** function. See the xSetAuxdata() method for details. ** ** If the bClear argument is non-zero, then the auxiliary data is cleared ** (set to NULL) before this function returns. In this case the xDelete, ** if any, is not invoked. ** ** ** xRowCount(pFts5, pnRow) ** ** This function is used to retrieve the total number of rows in the table. ** In other words, the same value that would be returned by: ** ** SELECT count(*) FROM ftstable; ** ** xPhraseFirst() ** This function is used, along with type Fts5PhraseIter and the xPhraseNext ** method, to iterate through all instances of a single query phrase within ** the current row. This is the same information as is accessible via the ** xInstCount/xInst APIs. While the xInstCount/xInst APIs are more convenient ** to use, this API may be faster under some circumstances. To iterate ** through instances of phrase iPhrase, use the following code: ** ** Fts5PhraseIter iter; ** int iCol, iOff; ** for(pApi->xPhraseFirst(pFts, iPhrase, &iter, &iCol, &iOff); ** iCol>=0; ** pApi->xPhraseNext(pFts, &iter, &iCol, &iOff) ** ){ ** // An instance of phrase iPhrase at offset iOff of column iCol ** } ** ** The Fts5PhraseIter structure is defined above. Applications should not ** modify this structure directly - it should only be used as shown above ** with the xPhraseFirst() and xPhraseNext() API methods (and by ** xPhraseFirstColumn() and xPhraseNextColumn() as illustrated below). ** ** This API can be quite slow if used with an FTS5 table created with the ** "detail=none" or "detail=column" option. If the FTS5 table is created ** with either "detail=none" or "detail=column" and "content=" option ** (i.e. if it is a contentless table), then this API always iterates ** through an empty set (all calls to xPhraseFirst() set iCol to -1). ** ** xPhraseNext() ** See xPhraseFirst above. ** ** xPhraseFirstColumn() ** This function and xPhraseNextColumn() are similar to the xPhraseFirst() ** and xPhraseNext() APIs described above. The difference is that instead ** of iterating through all instances of a phrase in the current row, these ** APIs are used to iterate through the set of columns in the current row ** that contain one or more instances of a specified phrase. For example: ** ** Fts5PhraseIter iter; ** int iCol; ** for(pApi->xPhraseFirstColumn(pFts, iPhrase, &iter, &iCol); ** iCol>=0; ** pApi->xPhraseNextColumn(pFts, &iter, &iCol) ** ){ ** // Column iCol contains at least one instance of phrase iPhrase ** } ** ** This API can be quite slow if used with an FTS5 table created with the ** "detail=none" option. If the FTS5 table is created with either ** "detail=none" "content=" option (i.e. if it is a contentless table), ** then this API always iterates through an empty set (all calls to ** xPhraseFirstColumn() set iCol to -1). ** ** The information accessed using this API and its companion ** xPhraseFirstColumn() may also be obtained using xPhraseFirst/xPhraseNext ** (or xInst/xInstCount). The chief advantage of this API is that it is ** significantly more efficient than those alternatives when used with ** "detail=column" tables. ** ** xPhraseNextColumn() ** See xPhraseFirstColumn above. */ struct Fts5ExtensionApi { int iVersion; /* Currently always set to 3 */ void *(*xUserData)(Fts5Context*); int (*xColumnCount)(Fts5Context*); int (*xRowCount)(Fts5Context*, sqlite3_int64 *pnRow); int (*xColumnTotalSize)(Fts5Context*, int iCol, sqlite3_int64 *pnToken); int (*xTokenize)(Fts5Context*, const char *pText, int nText, /* Text to tokenize */ void *pCtx, /* Context passed to xToken() */ int (*xToken)(void*, int, const char*, int, int, int) /* Callback */ ); int (*xPhraseCount)(Fts5Context*); int (*xPhraseSize)(Fts5Context*, int iPhrase); int (*xInstCount)(Fts5Context*, int *pnInst); int (*xInst)(Fts5Context*, int iIdx, int *piPhrase, int *piCol, int *piOff); sqlite3_int64 (*xRowid)(Fts5Context*); int (*xColumnText)(Fts5Context*, int iCol, const char **pz, int *pn); int (*xColumnSize)(Fts5Context*, int iCol, int *pnToken); int (*xQueryPhrase)(Fts5Context*, int iPhrase, void *pUserData, int(*)(const Fts5ExtensionApi*,Fts5Context*,void*) ); int (*xSetAuxdata)(Fts5Context*, void *pAux, void(*xDelete)(void*)); void *(*xGetAuxdata)(Fts5Context*, int bClear); int (*xPhraseFirst)(Fts5Context*, int iPhrase, Fts5PhraseIter*, int*, int*); void (*xPhraseNext)(Fts5Context*, Fts5PhraseIter*, int *piCol, int *piOff); int (*xPhraseFirstColumn)(Fts5Context*, int iPhrase, Fts5PhraseIter*, int*); void (*xPhraseNextColumn)(Fts5Context*, Fts5PhraseIter*, int *piCol); }; /* ** CUSTOM AUXILIARY FUNCTIONS *************************************************************************/ /************************************************************************* ** CUSTOM TOKENIZERS ** ** Applications may also register custom tokenizer types. A tokenizer ** is registered by providing fts5 with a populated instance of the ** following structure. All structure methods must be defined, setting ** any member of the fts5_tokenizer struct to NULL leads to undefined ** behaviour. The structure methods are expected to function as follows: ** ** xCreate: ** This function is used to allocate and initialize a tokenizer instance. ** A tokenizer instance is required to actually tokenize text. ** ** The first argument passed to this function is a copy of the (void*) ** pointer provided by the application when the fts5_tokenizer object ** was registered with FTS5 (the third argument to xCreateTokenizer()). ** The second and third arguments are an array of nul-terminated strings ** containing the tokenizer arguments, if any, specified following the ** tokenizer name as part of the CREATE VIRTUAL TABLE statement used ** to create the FTS5 table. ** ** The final argument is an output variable. If successful, (*ppOut) ** should be set to point to the new tokenizer handle and SQLITE_OK ** returned. If an error occurs, some value other than SQLITE_OK should ** be returned. In this case, fts5 assumes that the final value of *ppOut ** is undefined. ** ** xDelete: ** This function is invoked to delete a tokenizer handle previously ** allocated using xCreate(). Fts5 guarantees that this function will ** be invoked exactly once for each successful call to xCreate(). ** ** xTokenize: ** This function is expected to tokenize the nText byte string indicated ** by argument pText. pText may or may not be nul-terminated. The first ** argument passed to this function is a pointer to an Fts5Tokenizer object ** returned by an earlier call to xCreate(). ** ** The second argument indicates the reason that FTS5 is requesting ** tokenization of the supplied text. This is always one of the following ** four values: ** ** <ul><li> <b>FTS5_TOKENIZE_DOCUMENT</b> - A document is being inserted into ** or removed from the FTS table. The tokenizer is being invoked to ** determine the set of tokens to add to (or delete from) the ** FTS index. ** ** <li> <b>FTS5_TOKENIZE_QUERY</b> - A MATCH query is being executed ** against the FTS index. The tokenizer is being called to tokenize ** a bareword or quoted string specified as part of the query. ** ** <li> <b>(FTS5_TOKENIZE_QUERY | FTS5_TOKENIZE_PREFIX)</b> - Same as ** FTS5_TOKENIZE_QUERY, except that the bareword or quoted string is ** followed by a "*" character, indicating that the last token ** returned by the tokenizer will be treated as a token prefix. ** ** <li> <b>FTS5_TOKENIZE_AUX</b> - The tokenizer is being invoked to ** satisfy an fts5_api.xTokenize() request made by an auxiliary ** function. Or an fts5_api.xColumnSize() request made by the same ** on a columnsize=0 database. ** </ul> ** ** For each token in the input string, the supplied callback xToken() must ** be invoked. The first argument to it should be a copy of the pointer ** passed as the second argument to xTokenize(). The third and fourth ** arguments are a pointer to a buffer containing the token text, and the ** size of the token in bytes. The 4th and 5th arguments are the byte offsets ** of the first byte of and first byte immediately following the text from ** which the token is derived within the input. ** ** The second argument passed to the xToken() callback ("tflags") should ** normally be set to 0. The exception is if the tokenizer supports ** synonyms. In this case see the discussion below for details. ** ** FTS5 assumes the xToken() callback is invoked for each token in the ** order that they occur within the input text. ** ** If an xToken() callback returns any value other than SQLITE_OK, then ** the tokenization should be abandoned and the xTokenize() method should ** immediately return a copy of the xToken() return value. Or, if the ** input buffer is exhausted, xTokenize() should return SQLITE_OK. Finally, ** if an error occurs with the xTokenize() implementation itself, it ** may abandon the tokenization and return any error code other than ** SQLITE_OK or SQLITE_DONE. ** ** SYNONYM SUPPORT ** ** Custom tokenizers may also support synonyms. Consider a case in which a ** user wishes to query for a phrase such as "first place". Using the ** built-in tokenizers, the FTS5 query 'first + place' will match instances ** of "first place" within the document set, but not alternative forms ** such as "1st place". In some applications, it would be better to match ** all instances of "first place" or "1st place" regardless of which form ** the user specified in the MATCH query text. ** ** There are several ways to approach this in FTS5: ** ** <ol><li> By mapping all synonyms to a single token. In this case, using ** the above example, this means that the tokenizer returns the ** same token for inputs "first" and "1st". Say that token is in ** fact "first", so that when the user inserts the document "I won ** 1st place" entries are added to the index for tokens "i", "won", ** "first" and "place". If the user then queries for '1st + place', ** the tokenizer substitutes "first" for "1st" and the query works ** as expected. ** ** <li> By querying the index for all synonyms of each query term ** separately. In this case, when tokenizing query text, the ** tokenizer may provide multiple synonyms for a single term ** within the document. FTS5 then queries the index for each ** synonym individually. For example, faced with the query: ** ** <codeblock> ** ... MATCH 'first place'</codeblock> ** ** the tokenizer offers both "1st" and "first" as synonyms for the ** first token in the MATCH query and FTS5 effectively runs a query ** similar to: ** ** <codeblock> ** ... MATCH '(first OR 1st) place'</codeblock> ** ** except that, for the purposes of auxiliary functions, the query ** still appears to contain just two phrases - "(first OR 1st)" ** being treated as a single phrase. ** ** <li> By adding multiple synonyms for a single term to the FTS index. ** Using this method, when tokenizing document text, the tokenizer ** provides multiple synonyms for each token. So that when a ** document such as "I won first place" is tokenized, entries are ** added to the FTS index for "i", "won", "first", "1st" and ** "place". ** ** This way, even if the tokenizer does not provide synonyms ** when tokenizing query text (it should not - to do so would be ** inefficient), it doesn't matter if the user queries for ** 'first + place' or '1st + place', as there are entries in the ** FTS index corresponding to both forms of the first token. ** </ol> ** ** Whether it is parsing document or query text, any call to xToken that ** specifies a <i>tflags</i> argument with the FTS5_TOKEN_COLOCATED bit ** is considered to supply a synonym for the previous token. For example, ** when parsing the document "I won first place", a tokenizer that supports ** synonyms would call xToken() 5 times, as follows: ** ** <codeblock> ** xToken(pCtx, 0, "i", 1, 0, 1); ** xToken(pCtx, 0, "won", 3, 2, 5); ** xToken(pCtx, 0, "first", 5, 6, 11); ** xToken(pCtx, FTS5_TOKEN_COLOCATED, "1st", 3, 6, 11); ** xToken(pCtx, 0, "place", 5, 12, 17); **</codeblock> ** ** It is an error to specify the FTS5_TOKEN_COLOCATED flag the first time ** xToken() is called. Multiple synonyms may be specified for a single token ** by making multiple calls to xToken(FTS5_TOKEN_COLOCATED) in sequence. ** There is no limit to the number of synonyms that may be provided for a ** single token. ** ** In many cases, method (1) above is the best approach. It does not add ** extra data to the FTS index or require FTS5 to query for multiple terms, ** so it is efficient in terms of disk space and query speed. However, it ** does not support prefix queries very well. If, as suggested above, the ** token "first" is substituted for "1st" by the tokenizer, then the query: ** ** <codeblock> ** ... MATCH '1s*'</codeblock> ** ** will not match documents that contain the token "1st" (as the tokenizer ** will probably not map "1s" to any prefix of "first"). ** ** For full prefix support, method (3) may be preferred. In this case, ** because the index contains entries for both "first" and "1st", prefix ** queries such as 'fi*' or '1s*' will match correctly. However, because ** extra entries are added to the FTS index, this method uses more space ** within the database. ** ** Method (2) offers a midpoint between (1) and (3). Using this method, ** a query such as '1s*' will match documents that contain the literal ** token "1st", but not "first" (assuming the tokenizer is not able to ** provide synonyms for prefixes). However, a non-prefix query like '1st' ** will match against "1st" and "first". This method does not require ** extra disk space, as no extra entries are added to the FTS index. ** On the other hand, it may require more CPU cycles to run MATCH queries, ** as separate queries of the FTS index are required for each synonym. ** ** When using methods (2) or (3), it is important that the tokenizer only ** provide synonyms when tokenizing document text (method (2)) or query ** text (method (3)), not both. Doing so will not cause any errors, but is ** inefficient. */ typedef struct Fts5Tokenizer Fts5Tokenizer; typedef struct fts5_tokenizer fts5_tokenizer; struct fts5_tokenizer { int (*xCreate)(void*, const char **azArg, int nArg, Fts5Tokenizer **ppOut); void (*xDelete)(Fts5Tokenizer*); int (*xTokenize)(Fts5Tokenizer*, void *pCtx, int flags, /* Mask of FTS5_TOKENIZE_* flags */ const char *pText, int nText, int (*xToken)( void *pCtx, /* Copy of 2nd argument to xTokenize() */ int tflags, /* Mask of FTS5_TOKEN_* flags */ const char *pToken, /* Pointer to buffer containing token */ int nToken, /* Size of token in bytes */ int iStart, /* Byte offset of token within input text */ int iEnd /* Byte offset of end of token within input text */ ) ); }; /* Flags that may be passed as the third argument to xTokenize() */ #define FTS5_TOKENIZE_QUERY 0x0001 #define FTS5_TOKENIZE_PREFIX 0x0002 #define FTS5_TOKENIZE_DOCUMENT 0x0004 #define FTS5_TOKENIZE_AUX 0x0008 /* Flags that may be passed by the tokenizer implementation back to FTS5 ** as the third argument to the supplied xToken callback. */ #define FTS5_TOKEN_COLOCATED 0x0001 /* Same position as prev. token */ /* ** END OF CUSTOM TOKENIZERS *************************************************************************/ /************************************************************************* ** FTS5 EXTENSION REGISTRATION API */ typedef struct fts5_api fts5_api; struct fts5_api { int iVersion; /* Currently always set to 2 */ /* Create a new tokenizer */ int (*xCreateTokenizer)( fts5_api *pApi, const char *zName, void *pContext, fts5_tokenizer *pTokenizer, void (*xDestroy)(void*) ); /* Find an existing tokenizer */ int (*xFindTokenizer)( fts5_api *pApi, const char *zName, void **ppContext, fts5_tokenizer *pTokenizer ); /* Create a new auxiliary function */ int (*xCreateFunction)( fts5_api *pApi, const char *zName, void *pContext, fts5_extension_function xFunction, void (*xDestroy)(void*) ); }; /* ** END OF REGISTRATION API *************************************************************************/ #ifdef __cplusplus } /* end of the 'extern "C"' block */ #endif #endif /* _FTS5_H */ /******** End of fts5.h *********/ |

In pure C code, this involves doing a ** printf() with a big string containing all that text. But we have ** to insert special codes (ex: \n and \") for many common characters, ** which interferes with the readability of the HTML. ** ** This tool allows us to put raw HTML, without the special codes, in ** the middle of a C program. This program then translates the text ** into standard C by inserting all necessary backslashes and other ** punctuation. ** ** Enhancement #1: ** ** If the last non-whitespace character prior to the first "@" of a ** @-block is "=" or "," then the @-block is a string literal initializer ** rather than text that is to be output via cgi_printf(). Render it ** as such. ** ** Enhancement #2: ** ** Comments of the form: "|* @-comment: CC" (where "|" is really "/") ** cause CC to become a comment character for the @-substitution. ** Typical values for CC are "--" (for SQL text) or "#" (for Tcl script) ** or "//" (for C++ code). Lines of subsequent @-blocks that begin with ** CC are omitted from the output. ** ** Enhancement #3: ** ** If a non-enhancement #1 line ends in backslash, the backslash and the ** newline (\n) are not included in the argument to cgi_printf(). This ** is used to split one long output line across multiple source lines. */ #include <stdio.h> #include <ctype.h> #include <stdlib.h> #include <string.h> /* |

The last two rules are the HTML formatting rules. <h2>Formatting Rule Details</h2> 1. <b>Paragraphs.</b> Any sequence of one or more blank lines forms a paragraph break. Centered or right-justified paragraphs are not supported by wiki markup, but you can do these things if you need them using HTML. 2. <b>Bullet Lists.</b> A bullet list item is a line that begins with a single "*" character surrounded on both sides by two or more spaces or by a tab. Only a single level of bullet list is supported by wiki. For nested lists, use HTML. 3. <b>Enumeration Lists.</b> An enumeration list item is a line that begins with a single "#" character surrounded on both sides by two or more spaces or by a tab. Or it can be a number and a "." (ex: "5.") surrounded on both sides by two spaces or a tab. Only a single level of enumeration list is supported by wiki. For nested lists or for enumerations that count using letters or roman numerials, use HTML. 4. <b>Indented Paragraphs.</b> Any paragraph that begins with two or more spaces or a tab and which is not a bullet or enumeration list item is rendered indented. Only a single level of indentation is supported by wiki. Use HTML for deeper indentation. 5. <b>Hyperlinks.</b> Text within square brackets <nowiki>("[...]")</nowiki> becomes a hyperlink. The target can be a wiki page name, the artifact ID of a check-in or ticket, the name of an image, or a URL. By default, the target is displayed as the text of the hyperlink. But you can specify alternative text after the target name separated by a "|" character. You can also link to internal anchor names using <nowiki>[#anchor-name],</nowiki> providing you have added the necessary "<a name='anchor-name'></a>" tag to your wiki page. 6. <b>HTML.</b> The following standard HTML elements may be used: <a> <address> <article> <aside> <b> <big> <blockquote> <br> <center> <cite> <code> <col> <colgroup> <dd> <dfn> <div> <dl> <dt> <em> <font> <footer> <h1> <h2> <h3> <h4> <h5> <h6> <header> <hr> <i> <img> <kbd> <li> <nav> <nobr> <nowiki> <ol> <p> <pre> <s> <samp> <section> <small> <span> <strike> <strong> <sub> <sup> <table> <tbody> <td> <tfoot> <th> <thead> <title> <tr> <tt> <u> <ul> <var> <verbatim>. There are two non-standard elements available: <verbatim> and <nowiki>. No other elements are allowed. All attributes are checked and only a few benign attributes are allowed on each element. In particular, any attributes that specify javascript or CSS are elided. 7. <b>Special Markup.</b> The <nowiki> tag disables all wiki formatting rules through the matching </nowiki> element. The <verbatim> tag works like <pre> with the addition that it also disables all wiki and HTML markup through the matching </verbatim>. |

This article gives a quick background on how CGI works and describes how Fossil can act as a CGI service. <p>This is a "how it works" guide. If you just want to set up Fossil as a CGI server, see the [./server/ | Fossil Server Setup] page. </blockquote> <h2>A Quick Review Of CGI</h2><blockquote> <p> An HTTP request is a block of text that is sent by a client application (usually a web browser) and arrives at the web server over a network connection. The HTTP request contains a URL that describes the information being requested. The URL in the HTTP request is typically the same URL that appears in the URL bar at the top of the web browser that is making the request. The URL might contain a "?" character followed query parameters. The HTTP will usually also contain other information such as the name of the application that made the request, whether or not the requesting application can except a compressed reply, POST parameters from forms, and so forth. <p> The job of the web server is to interpret the HTTP request and formulate an appropriate reply. The web server is free to interpret the HTTP request in any way it wants. But most web servers follow a similar pattern, described below. (Note: details may vary from one web server to another.) <p> Suppose the URL in the HTTP request looks like this: <blockquote><b>/one/two/timeline/four</b></blockquote> Most web servers will search their content area for files that match some prefix of the URL. The search starts with <b>/one</b>, then goes to <b>/one/two</b>, then <b>/one/two/timeline</b>, and finally <b>/one/two/timeline/four</b> is checked. The search stops at the first match. <p> Suppose the first match is <b>/one/two</b>. If <b>/one/two</b> is an ordinary file in the content area, then that file is returned as static content. The "<b>/timeline/four</b>" suffix is silently ignored. <p> If <b>/one/two</b> is a CGI script (or program), then the web server executes the <b>/one/two</b> script. The output generated by the script is collected and repackaged as the HTTP reply. <p> Before executing the CGI script, the web server will set up various environment variables with information useful to the CGI script: <table border=1 cellpadding=5> <tr><th>Environment<br>Variable<th>Meaning <tr><td>GATEWAY_INTERFACE<td>Always set to "CGI/1.0" <tr><td>REQUEST_URI <td>The input URL from the HTTP request. <tr><td>SCRIPT_NAME <td>The prefix of the input URL that matches the CGI script name. In this example: "/one/two". <tr><td>PATH_INFO <td>The suffix of the URL beyond the name of the CGI script. In this example: "timeline/four". <tr><td>QUERY_STRING <td>The query string that follows the "?" in the URL, if there is one. </table> <p> There are other CGI environment variables beyond those listed above. Many Fossil servers implement the [https://www.fossil-scm.org/fossil/test_env/two/three?abc=xyz|test_env] webpage that shows some of the CGI environment variables that Fossil pays attention to. <p> In addition to setting various CGI environment variables, if the HTTP request contains POST content, then the web server relays the POST content to standard input of the CGI script. <p> In summary, the task of the CGI script is to read the various CGI environment variables and the POST content on standard input (if any), figure out an appropriate reply, then write that reply on standard output. The web server will read the output from the CGI script, reformat it into an appropriate HTTP reply, and relay the result back to the requesting application. The CGI script exits as soon as it generates a single reply. The web server will (usually) persist and handle multiple HTTP requests, but a CGI script handles just one HTTP request and then exits. <p> The above is a rough outline of how CGI works. There are many details omitted from this brief discussion. See other on-line CGI tutorials for further information. </blockquote> <h2>How Fossil Acts As A CGI Program</h2> <blockquote> An appropriate CGI script for running Fossil will look something like the following: <blockquote><pre> #!/usr/bin/fossil repository: /home/www/repos/project.fossil </pre></blockquote> The first line of the script is a "[https://en.wikipedia.org/wiki/Shebang_%28Unix%29|shebang]" that tells the operating system what program to use as the interpreter for this script. On unix, when you execute a script that starts with a shebang, the operating system runs the program identified by the shebang with a single argument that is the full pathname of the script itself. In our example, the interpreter is Fossil, and the argument might be something like "/var/www/cgi-bin/one/two" (depending on how your particular web server is configured). <p> The Fossil program that is run as the script interpreter is the same Fossil that runs when you type ordinary Fossil commands like "fossil sync" or "fossil commit". But in this case, as soon as it launches, the Fossil program recognizes that the GATEWAY_INTERFACE environment variable is set to "CGI/1.0" and it therefore knows that it is being used as CGI rather than as an ordinary command-line tool, and behaves accordingly. <p> When Fossil recognizes that it is being run as CGI, it opens and reads the file identified by its sole argument (the file named by <code>argv[1]</code>). In our example, the second line of that file tells Fossil the location of the repository it will be serving. Fossil then starts looking at the CGI environment variables to figure out what web page is being requested, generates that one web page, then exits. <p> Usually, the webpage being requested is the first term of the PATH_INFO environment variable. (Exceptions to this rule are noted in the sequel.) For our example, the first term of PATH_INFO is "timeline", which means that Fossil will generate the [/help?cmd=/timeline|/timeline] webpage. <p> With Fossil, terms of PATH_INFO beyond the webpage name are converted into the "name" query parameter. Hence, the following two URLs mean exactly the same thing to Fossil: <ol type='A'> <li> [https://www.fossil-scm.org/fossil/info/c14ecc43] <li> [https://www.fossil-scm.org/fossil/info?name=c14ecc43] </ol> In both cases, the CGI script is called "/fossil". For case (A), the PATH_INFO variable will be "info/c14ecc43" and so the "[/help?cmd=/info|/info]" webpage will be generated and the suffix of PATH_INFO will be converted into the "name" query parameter, which identifies the artifact about which information is requested. In case (B), the PATH_INFO is just "info", but the same "name" query parameter is set explicitly by the URL itself. </blockquote> <h2>Serving Multiple Fossil Repositories From One CGI Script</h2> <blockquote> The previous example showed how to serve a single Fossil repository using a single CGI script. On a website that wants to serve multiple repositories, one could simply create multiple CGI scripts, one script for each repository. But it is also possible to serve multiple Fossil repositories from a single CGI script. <p> If the CGI script for Fossil contains a "directory:" line instead of a "repository:" line, then the argument to "directory:" is the name of a directory that contains multiple repository files, each ending with ".fossil". For example: <blockquote><pre> #!/usr/bin/fossil directory: /home/www/repos </pre></blockquote> Suppose the /home/www/repos directory contains files named <b>one.fossil</b>, <b>two.fossil</b>, and <b>subdir/three.fossil</b>. Further suppose that the name of the CGI script (relative to the root of the webserver document area) is "cgis/example2". Then to see the timeline for the "three.fossil" repository, the URL would be: <blockquote> <b>http://example.com/cgis/example2/subdir/three/timeline</b> </blockquote> Here is what happens: <ol> <li> The input URI on the HTTP request is <b>/cgis/example2/subdir/three/timeline</b> <li> The web server searches prefixes of the input URI until it finds the "cgis/example2" script. The web server then sets PATH_INFO to the "subdir/three/timeline" suffix and invokes the "cgis/example2" script. <li> Fossil runs and sees the "directory:" line pointing to "/home/www/repos". Fossil then starts pulling terms off the front of the PATH_INFO looking for a repository. It first looks at "/home/www/resps/subdir.fossil" but there is no such repository. So then it looks at "/home/www/repos/subdir/three.fossil" and finds a repository. The PATH_INFO is shortened by removing "subdir/three/" leaving it at just "timeline". <li> Fossil looks at the rest of PATH_INFO to see that the webpage requested is "timeline". </ol> </blockquote> <h2>Additional CGI Script Options</h2> <blockquote> <p> The CGI script can have additional options used to fine-tune Fossil's behavior. See the [./cgi.wiki|CGI script documentation] for details. </p> </blockquote> <h2>Additional Observations</h2> <blockquote><ol type="I"> <li><p> Fossil does not distinguish between the various HTTP methods (GET, PUT, DELETE, etc). Fossil figures out what it needs to do purely from the webpage term of the URI. <li><p> Fossil does not distinguish between query parameters that are part of the URI, application/x-www-form-urlencoded or multipart/form-data encoded parameter that are part of the POST content, and cookies. Each information source is seen as a space of key/value pairs which are loaded into an internal property hash table. The code that runs to generate the reply can then reference various properties values. Fossil does not care where the value of each property comes from (POST content, cookies, or query parameters) only that the property exists and has a value. <li><p> The "[/help?cmd=ui|fossil ui]" and "[/help?cmd=server|fossil server]" commands are implemented using a simple built-in web server that accepts incoming HTTP requests, translates each request into a CGI invocation, then creates a separate child Fossil process to handle each request. In other words, CGI is used internally to implement "fossil ui/server". <p> SCGI is processed using the same built-in web server, just modified to parse SCGI requests instead of HTTP requests. Each SCGI request is converted into CGI, then Fossil creates a separate child Fossil process to handle each CGI request. <li><p> Fossil is itself often launched using CGI. But Fossil can also then turn around and launch [./serverext.wiki|sub-CGI scripts to implement extensions]. </ol> </blockquote> |

The "download.html" screen itself, and the various build products are all stored as unversioned content. The download.html page uses XMLHttpRequest() to retrieve the [/help?cmd=/juvlist|/juvlist] webpage for a list of all unversioned files. Javascript in the [/uv/download.js?mimetype=text/plain|download.js] file (which is sourced by "download.html") then figures out which unversioned files are build products and paints appropriate icons on the displayed download page. When a new version is generated, the developers use the [/help?cmd=uv|fossil uv edit] command to make minor changes to the "[/uv/download.js?mimetype=text/plain|download.js]" file so that it knows about the new version number. Then the developers run the [/help?cmd=uv|fossil uv add] command for each build product. Finally, the [/help?cmd=uv|fossil uv sync] command is run to push all the content up to servers. All [./selfhost.wiki|three self-hosting repositories] for Fossil are updated automatically. <h2>2.0 Details</h2> The current text of the "download.html" and "download.js" files can be seen at: * [/uv/download.html?mimetype=text/plain] * [/uv/download.js?mimetype=text/plain] Notice how the hyperlinks above use the "mimetype=text/plain" query parameter in order to display the file as plain text instead of the usual HTML or Javascript. The default mimetype for "download.html" is text/html. But because the entire page is enclosed within <b><div class='fossil-doc' data-title='Download Page'>...</div></b> Fossil knows to add its standard header and footer information to the document, making it look just like any other page. See "[./embeddeddoc.wiki|embedded documentation]" for further details on how <div class='fossil-doc'> this works. With each new release, the "releases" variable in the javascript on the [/uv/download.js?mimetype=text/plain|download.js] page is edited (using "[/help?cmd=uv|fossil uv edit download.js]") to add details of the release. When the JavaScript in the "download.js" file runs, it requests a listing of all unversioned content using the /juvlist URL. ([/juvlist|sample /juvlist output]). The content of the download page is constructed by matching unversioned files against regular expressions in the "releases" variable. Build products need to be constructed on different machines. The precompiled binary for Linux is compiled on Linux, the precompiled binary for Windows is compiled on Windows10, and so forth. After a new release is tagged, the release manager goes around to each of the target platforms, checks out the release and compiles it, then runs [/help?cmd=uv|fossil uv add] for the build product followed by [/help?cmd=uv|fossil uv sync] to push the new build product to the [./selfhost.wiki|various servers]. This process is repeated for each build product. When older builds are retired from the download page, the [/uv/download.js?mimetype=text/plain|download.js] page is again edited to remove the corresponding entry from the "release" variable and the edit is synced using [/help?cmd=uv|fossil uv sync]. This causes the build products to disappear from the download page immediately. But those build products are still taking up space in the unversioned content table of the server repository. To purge the obsolete build products, one or more [/help?cmd=uv|fossil uv rm] commands are run, followed by another [/help?cmd=uv|fossil uv sync]. It is important to purge obsolete build products since they take up a lot of space. At [/repo-tabsize] you can see that the unversioned table takes up a substantial fraction of the repository. <h2>3.0 Security</h2> Only users with the [/setup_ulist_notes|"y" permission] are allowed to push unversioned content up to the servers. Having the ability to push check-ins (the [/setup_ulist_notes|"i" permission]) is not sufficient. On the Fossil project there are 67 people (as of 2017-03-24) who have check-in privileges. But only 3 core developers can push unversioned content and thus change the build products on the download page. Minimizing the number of people who can change the build products helps to ensure that rogue binaries do not slip onto the download page unnoticed. |

New features can be added to a Fossil server using [./serverext.wiki|external CGI programs], but that is not what this article is about. This article focuses on how to make changes to Fossil itself. <h2>2.0 Programming Language</h2> Fossil is written in C-89. There are specific [./style.wiki | style guidelines] that are required for any new code that will be accepted into the Fossil core. But, of course, if you are writing an extension just for yourself, you can use any programming style you want. The source code for Fossil is not sent directly into the C compiler. There are three separate code [./makefile.wiki#preprocessing|preprocessors] that run over the code first. 1. The <b>mkindex</b> preprocessor scans all regular source files looking for special comments that contain "help" text and which identify routines that implement specific commands or which generate particular web pages. 2. The <b>makeheaders</b> preprocessor generates all the ".h" files automatically. Fossil programmers write ".c" files only and let the makeheaders preprocessor create the ".h" files. 3. The <b>translate</b> preprocessor converts source code lines that begin with "@" into string literals, or into print statements that generate web page output, depending on context. The [./makefile.wiki|Makefile] for Fossil takes care of running these preprocessors with all the right arguments and in the right order. So it is not necessary to understand the details of how these preprocessors work. (Though, the sources for all three preprocessors are included in the source tree and are well commented, if you want to dig deeper.) It is only necessary to know that these preprocessors exist and hence will effect the way you write code. <h2>3.0 Adding New Source Code Files</h2> New source code files are added in the "src/" subdirectory of the Fossil source tree. Suppose one wants to add a new source code file named "xyzzy.c". The first step is to add this file to the various makefiles. Do so by editing the file src/makemake.tcl and adding "xyzzy" (without the final ".c") to the list of source modules at the top of that script. Save the result and then run the makemake.tcl script using a TCL interpreter. The command to run the makemake.tcl script is: <b>tclsh makemake.tcl</b> The working directory must be src/ when the command above is run. Note that TCL is not normally required to build Fossil, but it is required for this step. If you do not have a TCL interpreter on your system already, they are easy to install. A popular choice is the [http://www.activestate.com/activetcl|Active Tcl] installation from ActiveState. After the makefiles have been updated, create the xyzzy.c source file from the following template: <blockquote><verbatim> /* ** Copyright boilerplate goes here. ***************************************************** ** High-level description of what this module goes ** here. */ #include "config.h" #include "xyzzy.h" #if INTERFACE /* Exported object (structure) definitions or #defines ** go here */ #endif /* INTERFACE */ /* New code goes here */ </verbatim></blockquote> Note in particular the <b>#include "xyzzy.h"</b> line near the top. The "xyzzy.h" file is automatically generated by makeheaders. Every normal Fossil source file must have a #include at the top that imports its private header file. (Some source files, such as "sqlite3.c" are exceptions to this rule. Don't worry about those exceptions. The files you write will require this #include line.) The "#if INTERFACE ... #endif" section is optional and is only needed if there are structure definitions or typedefs or macros that need to be used by other source code files. The makeheaders preprocessor uses definitions in the INTERFACE section to help it generate header files. See [../src/makeheaders.html | makeheaders.html] for additional information. After creating a template file such as shown above, and after updating the makefiles, you should be able to recompile Fossil and have it include your new source file, even before you source file contains any code. It is recommended that you try this. Be sure to [/help/add|fossil add] your new source file to the self-hosting Fossil repository and then [/help/commit|commit] your changes! <a name="newcmd"></a> <h2>4.0 Creating A New Command</h2> By "commands" we mean the keywords that follow "fossil" when invoking Fossil from the command-line. So, for example, in <b>fossil diff xyzzy.c</b> The "command" is "diff". Commands may optionally be followed by arguments and/or options. To create new commands in Fossil, add code (either to an existing source file, or to a new source file created as described above) according to the following template: <blockquote><verbatim> /* ** COMMAND: xyzzy ** ** Help text goes here. */ void xyzzy_cmd(void){ /* Implement the command here */ fossil_print("Hello, World!\n"); } </verbatim></blockquote> The example above creates a new command named "xyzzy" that prints the message "Hello, World!" on the console. This command is a normal command that will show up in the list of command from [/help/help|fossil help]. If you add an asterisk to the end of the command name, like this: <blockquote><verbatim> ** COMMAND: xyzzy* </verbatim></blockquote> Then the command will only show up if you add the "--all" option to [/help/help|fossil help]. Or, if the command name starts with "test" then the command will be considered experimental and will only show up when the --test option is used with [/help/help|fossil help]. The example above is a fully functioning Fossil command. You can add the text shown to an existing Fossil source file, recompiling then test it out by typing: <b>./fossil xyzzy<br> ./fossil help xyzzy<br> ./fossil xyzzy --help</b> The name of the C function that implements the command can be anything you like (as long as it does not collide with some other symbol in the Fossil code) but it is traditional to name the function "<i>commandname</i><b>_cmd</b>", as is done in the example. You could also use "printf()" instead of "fossil_print()" to generate the output text, if desired. But "fossil_print()" is recommended as it has extra logic to insert \r characters at the right times on Windows systems. Once you have the command running, you can then start adding code to make it do useful things. There are lots of utility functions in Fossil for parsing command-line options and for opening and accessing and manipulating the repository and the working check-out. Study implementations of existing commands to get an idea of how things are done. You can easily find the implementations of existing commands by searching for "COMMAND: <i>name</i>" in the files of the "src/" directory. <a name="newpage"></a> <h2>5.0 Creating A New Web Page</h2> As with commands, new webpages can be added simply by inserting a function that generates the webpage together with a special header comment. A template follows: <blockquote><verbatim> /* ** WEBPAGE: helloworld */ void helloworld_page(void){ style_header("Hello World!"); @ <p>Hello, World!</p> style_footer(); } </verbatim></blockquote> Add the code above to a new or existing Fossil source code file, then recompile fossil and run [/help/ui|fossil ui] then enter "http://localhost:8080/helloworld" in your web browser and the routine above will generate a web page that says "Hello World." It really is that simple. The special "WEBPAGE:" comment is picked up by the "mkindex" preprocessor and used to generate a table that maps the "helloworld" webpage name into a pointer to the "helloworld_page()" function. The function that implements a webpage can be named anything you like (as long as it does not collide with another name) but the traditional name is "<i>pagename</i><b>_page</b>". HTML pages begin with a call to style_header() and end with the call to style_footer(). Content is generated by the "@" lines that are translated (by the "translate" preprocessor) into printf-like code that generates the content of the webpage. Different techniques are used to generate non-HTML content. In the unlikely event that you need to generate non-HTML content, look at existing webpage implementations (ex: "logo" or "style.css") to see how that is done. There are lots of other things that a real web-page implementation will need to do, such verifying user credentials, parsing query parameters, and interacting with the repository. But now that you have the general idea of how webpages are implemented, you can look at the many other webpage implementations already built into Fossil to see how all that works. <h2>6.0 See Also</h2> * [./makefile.wiki|The Fossil Build Process] * [./tech_overview.wiki|A Technical Overview Of Fossil] * [./contribute.wiki|Contributing To The Fossil Project] * [./serverext.wiki|Adding CGI Extensions To A Fossil Server] |

Email alerts are sent by a [Fossil server](./server/), which must be [set up](#quick) by the Fossil administrator to send email. Email alerts do not currently work if you are only using Fossil from the command line. A bit of terminology: Fossil uses the terms "email alerts" and "notifications" interchangeably. We stick to the former term in this document except when referring to parts of the Fossil UI still using the latter term. ## Setup Prerequisites Much of this document describes how to set up Fossil's email alert system. To follow this guide, you will need a Fossil UI browser window open to the [Admin → Notification](/setup_notification) Fossil UI screen on the Fossil server that will be sending these email alerts, logged in as a user with [**Admin** capability](./caps/ref.html#a). It is not possible to work on a clone of the server's repository and push the configuration changes up to that repo as an Admin user, [on purpose](#backup). **Important:** Do not confuse that screen with Admin → Email-Server, which sets up a different subsystem within Fossil. That feature is related to this document's topic, but it is currently incomplete, so we do not cover it at this time. <a id="cd"></a> You will also need a CLI window open with its working directory changed to a checkout directory of the Fossil repository you are setting up to send email. If you don't `cd` to such a checkout directory first, you'll need to add `-R /path/to/repo.fossil` to each `fossil` command below to tell Fossil which repository you mean it to apply the command to. There are other prerequisites for email service, but since they vary depending on the configuration you choose, we'll cover these inline below. <a id="quick"></a> ## Quick Email Service Setup If you've already got a working Postfix, Exim, or Sendmail server on the machine running your Fossil instance(s), and you aren't using Fossil's `chroot` feature to wall Fossil off from the rest of the machine, it's fairly simple to set up email alerts. (Otherwise, skip [ahead](#advanced) to the sections on advanced email service setup.) This is our "quick setup" option even though setting up an SMTP mail server is not trivial, because there are many other reasons to have such a server set up already: internal project email service, `cron` notifications, server status monitoring notifications... With that out of the way, the Fossil-specific steps are easy: 1. Go to [Admin → Notification](/setup_notification) and fill out all of the **Required** fields: * **Canonical server URL** — Use the suggested URL * **"From" email address** — `forum-bounces@example.com` is traditional, but suit yourself * **Repository nickname** — See the suggested examples on the web page. 2. Set "Email Send Method" to "Pipe to a command" 3. Set the "Administrator email address" to a suitable valid email address on that machine. It could be the same value you used for the "From" address above, or it could be a different value like `admin@example.com`. Save your changes. At the command line, say $ fossil set email-send-command If that gives a blank value instead of `sendmail -ti`, say $ fossil set email-send-command "sendmail -ti" to force the setting. That works around a [known bug](https://fossil-scm.org/forum/forumpost/840b676410) which may be squished by the time you read this. If you're running Postfix or Exim, you might think that command is wrong, since you aren't running Sendmail. These mail servers provide a `sendmail` command for compatibility with software like Fossil that has no good reason to care exactly which SMTP server implementation is running at a given site. There may be other SMTP servers that also provide a compatible `sendmail` command, in which case they may work with Fossil using the same steps as above. <a id="status"></a> If you reload the Admin → Notification page, the Status section at the top should show: Outgoing Email: Piped to command "sendmail -ti" Pending Alerts: 0 normal, 0 digest Subscribers: 0 active, 0 total Before you move on to the next section, you might like to read up on [some subtleties](#pipe) with the "pipe to a command" method that we did not cover above. <a id="usage"></a> ## Usage and Testing Now that email service from Fossil is set up, you can test it and begin using it. <a id="sub" name="subscribe"></a> ### Subscribing to Alerts In the Status output above, we saw that there are no subscribers, so the next step is to add the first one. Go to the `/subscribe` page on your Fossil instance to sign up for email alerts. At the very least, you will need to sign up for "Forum Posts" and "Announcements" to complete the testing steps below. If you're logged in with a Fossil repository user account and put the same user name and email address into this forum as you used for your user information under Admin → Users, Fossil will simply tie your alert preferences to your login record, and the email address in your user's Contact Info field will be considered already-verified. Otherwise, Fossil will create an alert-only record, and you will have to verify the email address before Fossil will send alerts to it. This shows a key aspect of the way Fossil's email alerts system works, by the way: a user can be signed up for email alerts without having a full-fledged Fossil user account. Only when both user names are the same are the two records tied together under the hood. For more on this, see [Users vs Subscribers below](#uvs). If you are seeing the following complaint from Fossil: <blockquote> Use a different login with greater privilege than FOO to access /subscribe </blockquote> ...then the repository's administrator forgot to give the [**EmailAlert** capability][cap7] to that user or to a user category that the user is a member of. After a subscriber signs up for alerts for the first time, a single verification email is sent to that subscriber's given email address. The new subscriber must click a link in that email in order to activate the subscription. Subscription verification emails are only sent once. This is a defense against malicious robots that try to harass innocent Internet users by having subscription pages send multiple verification emails. If the initial subscription verification does not go through correctly, an administrator must [intervene](#admin) to reset the subscription. Every subscriber-only email address has a [long random hexadecimal security code](#scode) that serves in place of a password. All email alerts contain a link in their footer back to the Fossil server, incorporating this security code, which allows the subscriber to adjust their subscription options. If a user doesn't have any of those emails, they can request a link via email by visiting the `/alerts` or `/unsubscribe` page on the repository. Those with Fossil repository logins can adjust their email alert settings by visiting the `/alerts` page on the repository. With the default skin, you can get there by clicking the "Logout" link in the upper right corner of any Fossil UI page then clicking the "Email Alerts" link. That link is also available via the Sitemap (`/sitemap`) and via the default skin's hamburger menu (☰). [cap7]: ./caps/ref.html#7 <a id="unsub" name="unsubscribe"></a> ### Unsubscribing To unsubscribe from alerts, visit the `/alerts` page on the repository, click the "Unsubscribe" button, then check the "Unsubscribe" checkbox to verify your action and press the "Unsubscribe" button a second time. This interlock is intended to prevent accidental unsubscription. <a id="test"></a> ### Test Email Service The easiest way to test email sending from Fossil is via the "[Send Announcement](/announce)" link at the top of the "Email Notification Setup" page. Put your email address in the "To:" line and a test message below, then press "Send Message" to verify that outgoing email is working. Another method is from the command line: $ fossil alerts test-message you@example.com --body README.md --subject Test That should send you an email with "Test" in the subject line and the contents of your project's `README.md` file in the body. That command assumes that your project contains a "readme" file, but of course it does, because you have followed the [Programming Style Guide Checklist][cl], right? Right. [cl]: https://sendgrid.com/blog/programming-style-guide-checklist/ <a id="cap7" name="ucap"></a> ### User Capabilities Once email alerts are working, you may need to [adjust the default user capabilities](./caps/) to give "[Email Alerts][cap7]" capability to any [user category](./caps/#ucat) or [individual user](./caps/#ucap) that needs to use the subscription setup pages, `/subscribe` and `/alerts`. [**Admin**][capa] and [**Setup**][caps] users always have this capability. To allow any passer-by on the Internet to subscribe, give the "Email Alerts" capability to the "nobody" user category. To require that a person solve a simple CAPTCHA first, give that capability to the "anonymous" user category instead. [capa]: ./caps/ref.html#a [caps]: ./caps/ref.html#s <a id="first" name="frist"></a> ### First Post I suggest taking the time to compose a suitable introductory message especially for your project's forum, one which a new user would find helpful. Wait a few seconds, and you should receive an email alert with the post's subject and body text in the email. <a id="trouble"></a> ### Troubleshooting If email alerts aren't working, there are several useful commands you can give to figure out why. (Be sure to [`cd` into a repo checkout directory](#cd) first!) $ fossil alerts status This should give much the same information as you saw [above](#status). One difference is that, since you've created a forum post, the `pending-alerts` value should only be zero if you did in fact get the requested email alert. If it's zero, check your mailer's spam folder. If it's nonzero, continue with these troubleshooting steps. $ fossil backoffice That forces Fossil to run its ["back office" process](./backoffice.md). Its only purpose at the time of this writing is to push out alert emails, but it might do other things later. Sometimes it can get stuck and needs to be kicked. For that reason, you might want to set up a crontab entry to make sure it runs occasionally. $ fossil alerts send This should also kick off the backoffice processing, if there are any pending alerts to send out. $ fossil alert pending Show any pending alerts. The number of lines output here should equal the [status output above](#status). $ fossil test-add-alerts f5900 $ fossil alert send Manually create an email alert and push it out immediately. The `f` in the first command's final parameter means you're scheduling a "forum" alert. The integer is the ID of a forum post, which you can find by visiting `/timeline?showid` on your Fossil instance. The second command above is necessary because the `test-add-alerts` command doesn't kick off a backoffice run. $ fossil ale send This only does the same thing as the final command above, rather than send you an ale, as you might be hoping. Sorry. <a id="advanced"></a> ## Advanced Email Setups Fossil offers several methods of sending email: 1. Pipe the email message text into a command. 2. Store email messages as entries in a SQLite database. 3. Store email messages as individual files in a directory. 4. Send emails to an SMTP relay. 5. Send emails directly to the recipients via SMTP. This wide range of options allows Fossil to talk to pretty much any SMTP setup. The first four options let Fossil delegate email handling to an existing [MTA][mta] so that Fossil does not need to implement the [roughly two dozen][mprotos] separate [RFCs][rfcs] required in order to properly support SMTP email in this complex world we've built. As well, this design choice means you do not need to do duplicate configuration, such as to point Fossil at your server's TLS certificate in order to support users behind mail servers that require STARTTLS encryption. [mprotos]: http://sqlite.1065341.n5.nabble.com/Many-ML-emails-going-to-GMail-s-SPAM-tp98685p98722.html [rfcs]: https://en.wikipedia.org/wiki/Request_for_Comments <a id="pipe"></a> ### Method 1: Pipe to a Command This is our ["quick setup" option](#quick) above, but there are some details we ignored which we'll cover now. Fossil pipes the email message in [RFC 822 format][rfc822] to the standard input of the command you gave as the "Email Send Method", defaulting to `sendmail -ti`. This constitutes a protocol between Fossil and the SMTP [message transfer agent (MTA)][mta]. Any other MTA which speaks the same protocol can be used in place of the most common options: Sendmail, Exim, and Postfix. The `-t` option tells the command to expect the list of email recipients in a `To` header in the RFC 822 message presented on its standard input. Without this option, the `sendmail` command expects to receive the recipient list on the command line, but that's not possible with the current design of this email sending method. Therefore, if you're attempting to use a less common MTA which cannot parse the recipient list from the `To` header in the email message, you might need to look for a different MTA. The `-i` option is only needed for MTAs that take a dot/period at the beginning of a line of standard input text as "end of message." Fossil doesn't attempt to escape such dots, so if the line wrapping happens to occur such that a dot or period in an alert message is at the beginning of a line, you'll get a truncated email message without this option. Statistically, this will happen about once every 70 or so messages, so it is important to give this option if your MTA treats leading dots on a line this way. <a id="msmtp"></a> We believe the [`msmtp`][msmtp] SMTP client is compatible with this protocol if you give it the `-t` option. To our knowledge, this remains untested, but if it works, this would be a useful option on a server hosting a Fossil repository which doesn't otherwise require a separate SMTP server for other purposes. It is probably also possible to configure [`procmail`][pmdoc] to work with this protocol. If you know how to do it, a patch to this document or a how-to on [the Fossil forum][ff] would be appreciated. [ff]: https://fossil-scm.org/forum/ [msmtp]: https://marlam.de/msmtp/ [mta]: https://en.wikipedia.org/wiki/Message_transfer_agent [pmdoc]: http://pm-doc.sourceforge.net/doc/ [rfc822]: https://www.w3.org/Protocols/rfc822/ <a id="db"></a> ### Method 2: Store in a Database The self-hosting Fossil repository at <https://www.fossil-scm.org/> currently uses this method rather than [the pipe method](#pipe) because it is running inside of a restrictive [chroot jail][cj] which is unable to hand off messages to the local MTA directly. When you configure a Fossil server this way, it adds outgoing email messages to a SQLite database file. A separate daemon process can then extract those messages for further disposition. Fossil includes a copy of [the daemon](/file/tools/email-sender.tcl) used on `fossil-scm.org`: it is just a short Tcl script that continuously monitors this database for new messages and hands any that it finds off to a local MTA using the same [pipe to MTA protocol](#pipe) as above. In this way, outbound email alerts escape the chroot jail without requiring that we insert a separate MTA configuration inside that jail. We only need to arrange that the same SQLite DB file be visible both inside and outside the chroot jail, which we do by naming the database file in the "Store Emails In This Database" setting under Admin → Notification. The Tcl script has this path hard-coded as `/home/www/fossil/emailqueue.db`, but you will probably need to adjust that for your local purposes. This method may work with other similar technologies besides `chroot`: Docker containers, LXC containers, BSD jails, Solaris zones, etc. With suitable file share mappings, this method may even work with virtual machine or distributed computing setups where the MTA and Fossil servers are not on the same machine, though beware the [risk of DB corruption][rdbc] if used with a file sharing technology that doesn't use proper file locking. You can start this Tcl script as a daemon automatically on most Unix and Unix-like systems by adding the following line to the `/etc/rc.local` file of the server that hosts the repository sending email alerts: /usr/bin/tclsh /home/www/fossil/email-sender.tcl & [cj]: https://en.wikipedia.org/wiki/Chroot [rdbc]: https://www.sqlite.org/howtocorrupt.html#_filesystems_with_broken_or_missing_lock_implementations <a id="dir"></a> ### Method 3: Store in a Directory This method is functionally very similar to [the DB method](#db), differing only in that messages are written to a directory in the filesystem. You should therefore read that section and make the minor adjustments required by the storage method. This method may work over a file sharing mechanism that doesn't do file locking properly, as long as the reading process is somehow restricted from reading a message file as it's being written. It might be useful in testing and debugging to temporarily switch to this method, since you can easily read the generated email messages without needing to involve [an MTA][mta]. <a id="relay"></a> ### Method 4: SMTP Relay In this configuration, the Fossil server contacts an open SMTP relay and sends the messages to it. This method is only appropriate when: 1. You have a local MTA that doesn't accept [the pipe protocol](#pipe). 2. The MTA is willing to accept anonymous submissions, since Fossil currently has no way to authenticate itself to the MTA. This is [an unsafe configuration][omr] in most cases, but some SMTP servers make an exception for connections coming from a `localhost` or LAN address, choosing to accept such submissions as inherently safe. If you have a local MTA meeting criterion #1 but not #2, we'd suggest using a more powerful SMTP client such as [msmtp](#msmtp) along with one of the other methods above. [omr]: https://en.wikipedia.org/wiki/Open_mail_relay <a id="direct"></a> ### Method 5: Direct SMTP Send As of Fossil 2.7, the code to support this method is incomplete, so you cannot currently select it as an option in Admin → Notification. <a id="uvs"></a> ## Users vs Subscribers Fossil makes a distinction between "users" and "subscribers". A user is someone with a username and password: that is, someone who can log into the Fossil repository. A subscriber is someone who receives email alerts. Users can also be subscribers and subscribers can be users, but that does not have to be the case. It is possible to be a user without being a subscriber and to be a subscriber without being a user. In the repository database file, users are tracked with the `user` table and subscribers are tracked via the `subscriber` table. <a id="admin"></a> ## Administrator Activities The "[List Subscribers](/subscribers)" button at the top of the Admin → Notification screen gives a list of subscribers, which gives a Fossil server administrator a lot of power over those subscriptions. Clicking an email address in this subscriber list opens the same `/alerts` page that the user can see for their own subscription, but with more information and functionality than normal users get: * Subscription creation and modification timestamps. * The IP address the user had when they last made a change via either `/subscribe` or `/alert`. * The user's login name, if they are not [a mere subscriber](#uvs). A Fossil Admin user is allowed to modify this, either to tie a subscription-only record to an existing Fossil user account or to break that tie. * The "Do not call" checkbox allows a Fossil Admin user to mark a given email address so that Fossil never sends email to that address. This is distinct from unsubscribing that email address because it prevents Fossil from accepting a new subscription for that address. * The Verified checkbox is initially unchecked for subscriber-only email addresses until the user clicks the link in the verification email. This checkbox lets the Fossil Admin user manually verify the user, such as in the case where the verification email message got lost. Unchecking this box does not cause another verification email to be sent. This screen also allows a Fossil Admin user to perform other activities on behalf of a subscriber which they could do themselves, such as to [unsubscribe](#unsub) them. <a id="backup"></a> ## Cloning, Syncing, and Backups The Admin → Notification settings are not replicated using clone or sync, and it is not possible to push such settings from one repository to another. In a network of peer repositories, you only want one repository sending email alerts. If you were to replicate the email alert settings to a separate repository, then subscribers would get multiple alerts for each event, which would be bad. However, the subscriber list can be synced for backup purposes. Use the [`fossil config pull subscriber`](/help?cmd=configuration) command to pull the latest subscriber list from a server into a backup repository. The `push`, `export`, and `import` commands all work similarly. <a id="pages" name="commands"></a> ## Controlling the Email Alert System This section collects the list of Fossil UI pages and CLI commands that control the email alert system, some of which have not been mentioned so far: Commands: * The [`alerts`](/help?cmd=alerts) command * The [`test-alert`](/help?cmd=test-alert) command * The [`test-add-alerts`](/help?cmd=test-add-alerts) command Web pages available to users and subscribers: * The [`/subscribe`](/help?cmd=/subscribe) page * The [`/alerts`](/help?cmd=/alerts) page * The [`/unsubscribe`](/help?cmd=/unsubscribe) page * The [`/contact_admin`](/help?cmd=/contact_admin) page Administrator-only web pages: * The [`/setup_notification`](/help?cmd=/setup_notification) page * The [`/subscribers`](/help?cmd=/subscribers) page <a id="design"></a> ## Design of Email Alerts This section describes the low-level design of the email alert system in Fossil. This expands on the high-level administration focused material above with minimal repetition. This section assumes expert-level systems knowledge. If the material above sufficed for your purposes, feel free to skip this section, which runs to the end of this document. <a id="datades"></a> ### Data Design There are three new tables in the repository database, starting with Fossil 2.7. These tables are not created in new repositories by default. The tables only come into existence as needed when email alerts are configured and used. * <b>SUBSCRIBER</b> → The subscriber table records the email address for people who want to receive email notifications. Each subscriber has a `subscriberCode` which is a random 32-byte blob that uniquely identifies the subscriber. There are also fields to indicate what kinds of notifications the subscriber wishes to receive, whether or not the email address of the subscriber has been verified, etc. * <b>PENDING\_ALERT</b> → The PENDING\_ALERT table contains records that define events about which alert emails might need to be sent. A pending\_alert always refers to an entry in the EVENT table. The EVENT table is part of the standard schema and records timeline entries. In other words, there is one row in the EVENT table for each possible timeline entry. The PENDING\_ALERT table refers to EVENT table entries for which we might need to send alert emails. * <b>EMAIL\_BOUNCE</b> → This table is intended to record email bounce history so that subscribers with excessive bounces can be turned off. That logic has not yet been implemented so the EMAIL\_BOUNCE table is currently unused. As pointed out above, ["subscribers" are distinct from "users"](#uvs). The SUBSCRIBER.SUNAME field is the optional linkage between users and subscribers. <a id="stdout"></a> ### The "stdout" Method The [list of mail sending methods](#advanced) above left out an internal-only method called "stdout" which simply writes the text of the email message on standard output. The "stdout" method is used for testing and debugging. If you need something similar and can't modify your local Fossil instance to use this method, you might temporarily switch to [the "dir" method](#dir) instead. <a id="msgfmt"></a> ### Message Format The email messages generated by Fossil have a [well-formed header][rfc822]. The downstream processing is expected to extract the "To:", "From:", "Subject:" and whatever other attributes it needs from the email header text. These emails use the `text/plain` MIME type with the UTF-8 character set. We currently use a transfer encoding of `quoted-printable`, but there is commented-out code in Fossil to switch to `base64` encoding, which Fossil used in the early days leading up to the 2.7 release. If you switch Fossil back to `base64` mode, you may want to build a utility program that ships in the Fossil source tree named ["tools/decode-email.c"](/file/tools/decode-email.c) which can decode these messages into a human-readable format. <a id="inbound" name="bounces"></a> ### Dealing with Inbound Email Inbound email messages — for example, bounces from failed alert emails — should be relayed to the `fossil email inbound` command. That command is currently a no-op place-holder. At some point, we will need to design and write a bounce-message processing system for Fossil. <a id="password" name="scode" name="verification"></a> ### Passwords vs Subscriber Codes When anonymous passers-by on the Internet sign up for email alerts, their email address must first be verified. An email message is sent to the address supplied inviting the user to click on a link. The link includes a pseudorandom 128-bit blob encoded as 32 hexadecimal digits, which serves in place of a password for that email address. (This is stored in the database as `subscriber.subscriberCode`.) If anyone visits the link, the email address is verified. Knowledge of the `subscriberCode` is sufficient to control a subscription. Because this code is included in plain text in email alert messages, it is not as secure as a separate password, but it has several virtues: * It is easier for the average subscriber to deal with in that they don't have to come up with yet another password and store it safely. * If the `subscriberCode` is stolen, the worst that can happen is that the thief can change that email address's subscription settings. Contrast a password which may be shared with other services, which then compromises those other services. * No PII other than the subscriber's email address is available to an attacker with the `subscriberCode`. Nor can knowledge of the `subscriberCode` lead to a email flood or other annoyance attack, as far as I can see. If the `subscriberCodes` for a Fossil repository are ever compromised, new ones can be generated as follows: UPDATE subscriber SET subscriberCode=randomblob(32); Since this then affects all new email alerts going out from Fossil, your end users may never even realize that they're getting new codes, as long as they don't click on the URLs in the footer of old alert messages. With that in mind, a Fossil server administrator could choose to randomize the `subscriberCodes` periodically, such as just before the daily digest emails are sent out each day. **Important:** All of the above is distinct from the passwords for users with a Fossil repository login. Such users also have subscriber codes, but those codes can only be used to modify the user's email alert settings. That code cannot allow a user to log into the user's Fossil repository account. <a id="processing"></a> ### Internal Processing Flow Almost all of the email alert code is found in the [`src/alerts.c`](/file/src/alerts.c) source file. When email alerts are enabled, a trigger is created in the schema (`email_trigger1`) that adds a new entry to the `PENDING_ALERT` table every time a row is added to the `EVENT` table. During a `fossil rebuild`, the `EVENT` table is rebuilt from scratch; since we do not want users to get alerts for every historical check-in, the trigger is disabled during `rebuild`. Email alerts are sent out by the `alert_send_alerts()` function, which is normally called automatically due to the `email-autoexec` setting, which defaults to enabled. If that setting is disabled or if the user simply wants to force email alerts to be sent immediately, they can give a `fossil alert send` command, such as via a `cron` script. Each time this function is called, the alert messages are moved further down the chain, so you cannot cause duplicate alerts by calling it too often. Digests are handled by recording the time of the last digest in the `email-last-digest` setting, and only sending a new digest if the current time is one day or later after the last digest. Individual emails are sent to each subscriber. I (drh) ran tests and found that I could send about 1200 emails/second, which is fast enough that I do not need to resort to trying to notify multiple subscribers with a single email. Because each subscriber gets a separate email, the system can include information in the email that is unique to the subscriber, such as a link to the page to edit their subscription. That link includes the `subscriberCode`. |

Even a modest project can have millions of pages in its tree, and many of those pages (for example diffs and annotations and ZIP archives of older check-ins) can be expensive to compute. If a spider or bot tries to walk a website implemented by Fossil, it can present a crippling bandwidth and CPU load. The website presented by a Fossil server is intended to be used interactively by humans, not walked by spiders. This article describes the techniques used by Fossil to try to welcome human users while keeping out spiders. <h2>The Hyperlink User Capability</h2> Every Fossil web session has a "user". For random passers-by on the internet (and for spiders) that user is "nobody". The "anonymous" user is also available for humans who do not wish to identify themselves. The difference is that "anonymous" requires a login (using a password supplied via a CAPTCHA) whereas "nobody" does not require a login. The site administrator can also create logins with passwords for specific individuals. Users without the <b>[./caps/ref.html#h | Hyperlink]</b> capability do not see most Fossil-generated hyperlinks. This is a simple defense against spiders, since [./caps/#ucat | the "nobody" user category] does not have this capability by default. Users must log in (perhaps as "anonymous") before they can see any of the hyperlinks. A spider that cannot log into your Fossil repository will be unable to walk its historical check-ins, create diffs between versions, pull zip archives, etc. by visiting links, because they aren't there. A text message appears at the top of each page in this situation to invite humans to log in as anonymous in order to activate hyperlinks. Because this required login step is annoying to some, Fossil provides other techniques for blocking spiders which are less cumbersome to humans. <h2>Automatic Hyperlinks Based on UserAgent</h2> Fossil has the ability to selectively enable hyperlinks for users that lack the <b>Hyperlink</b> capability based on their UserAgent string in the HTTP request header and on the browsers ability to run Javascript. The UserAgent string is a text identifier that is included in the header of most HTTP requests that identifies the specific maker and version of the browser (or spider) that generated the request. Typical UserAgent strings look like this: <ul> <li> Mozilla/5.0 (Windows NT 6.1; rv:19.0) Gecko/20100101 Firefox/19.0 <li> Mozilla/4.0 (compatible; MSIE 8.0; Windows_NT 5.1; Trident/4.0) <li> Mozilla/5.0 (compatible; Googlebot/2.1; +http://www.google.com/bot.html) <li> Wget/1.12 (openbsd4.9) </ul> The first two UserAgent strings above identify Firefox 19 and Internet Explorer 8.0, both running on Windows NT. The third example is the spider used by Google to index the internet. The fourth example is the "wget" utility running on OpenBSD. Thus the first two UserAgent strings above identify the requester as human whereas the second two identify the requester as a spider. Note that the UserAgent string is completely under the control of the requester and so a malicious spider can forge a UserAgent string that makes it look like a human. But most spiders truly seem to desire to "play nicely" on the internet and are quite open about the fact that they are a spider. And so the UserAgent string provides a good first-guess about whether or not a request originates from a human or a spider. In Fossil, under the Admin/Access menu, there is a setting entitled "<b>Enable hyperlinks for "nobody" based on User-Agent and Javascript</b>". If this setting is enabled, and if the UserAgent string looks like a human and not a spider, then Fossil will enable hyperlinks even if the <b>Hyperlink</b> capability is omitted from the user permissions. This setting gives humans easy access to the hyperlinks while preventing spiders from walking the millions of pages on a typical Fossil site. But the hyperlinks are not enabled directly with the setting above. Instead, the HTML code that is generated contains anchor tags ("<a>") without "href=" attributes. Then, JavaScript code is added to the end of the page that goes back and fills in the "href=" attributes of the anchor tags with the hyperlink targets, thus enabling the hyperlinks. This extra step of using JavaScript to enable the hyperlink targets is a security measure against spiders that forge a human-looking UserAgent string. Most spiders do not bother to run JavaScript and so to the spider the empty anchor tag will be useless. But all modern web browsers implement JavaScript, so hyperlinks will show up normally for human users. <h2>Further Defenses</h2> Recently (as of this writing, in the spring of 2013) the Fossil server on the SQLite website ([http://www.sqlite.org/src/]) has been hit repeatedly by Chinese spiders that use forged UserAgent strings to make them look like normal web browsers and which interpret JavaScript. We do not believe these attacks to be nefarious since SQLite is public domain and the attackers could obtain all information they ever wanted to know about SQLite simply by cloning the repository. Instead, we believe these "attacks" are coming from "script kiddies". But regardless of whether or not malice is involved, these attacks do present an unnecessary load on the server which reduces the responsiveness of the SQLite website for well-behaved and socially responsible users. For this reason, additional defenses against spiders have been put in place. On the Admin/Access page of Fossil, just below the "<b>Enable hyperlinks for "nobody" based on User-Agent and Javascript</b>" setting, there are now two additional sub-settings that can be optionally enabled to control hyperlinks. The first sub-setting waits to run the JavaScript that sets the "href=" attributes on anchor tags until after at least one "mouseover" event has been detected on the <body> element of the page. The thinking here is that spiders will not be simulating mouse motion and so no mouseover events will ever occur and hence the hyperlinks will never become enabled for spiders. The second new sub-setting is a delay (in milliseconds) before setting the "href=" attributes on anchor tags. The default value for this delay is 10 milliseconds. The idea here is that a spider will try to render the page immediately, and will not wait for delayed scripts to be run, thus will never enable the hyperlinks. These two sub-settings can be used separately or together. If used together, then the delay timer does not start until after the first mouse movement is detected. See also [./loadmgmt.md|Managing Server Load] for a description of how expensive pages can be disabled when the server is under heavy load. <h2>The Ongoing Struggle</h2> Fossil currently does a very good job of providing easy access to humans while keeping out troublesome robots and spiders. However, spiders and bots continue to grow more sophisticated, requiring ever more advanced defenses. This "arms race" is unlikely to ever end. The developers of Fossil will continue to try improve the spider defenses of Fossil so check back from time to time for the latest releases and updates. Readers of this page who have suggestions on how to improve the spider defenses in Fossil are invited to submit your ideas to the Fossil Users forum: [https://fossil-scm.org/forum]. |

Ordinary Fossil users do not need to know about anything covered by this document. The information here is intended for people who want to enhance or extend the Fossil code, or who just want a deeper understanding of the internal workings of Fossil. What Is The Backoffice ---------------------- The backoffice is a mechanism used by a [Fossil server](./server/) to do low-priority background work that is not directly related to the user interface. Here are some examples of the kinds of work that backoffice performs: 1. Sending email alerts and notifications 2. Sending out daily digests of email notifications 3. Other background email handling chores 4. Automatic syncing of peer repositories 5. Repository maintenance and optimization (As of 2018-08-07, only items 1 and 2 have actually been implemented.) The idea is that the backoffice handles behind-the-scenes work that does not have tight latency requirements. When Backoffice Runs -------------------- A backoffice process is usually launched automatically by a webpage request. After each webpage is generated, Fossil checks to see if any backoffice work needs to be done. If there is work to do, and no other process is already assigned to do the work, then a new backoffice process is started to do the work. This happens for every webpage, regardless of how that webpage is launched, and regardless of the purpose of the webpage. This also happens on the server for "[fossil sync](/help?cmd=sync)" and [fossil clone](/help?cmd=clone)" commands which are implemented as web requests - albeit requests that the human user never sees. Web requests can arrive at the Fossil server via direct TCP/IP (for example when Fossil is started using commands like "[fossil server](/help?cmd=server)") or via [CGI](./server/any/cgi.md) or [SCGI](./server/any/scgi.md) or via SSH. A backoffice process might be started regardless of the origin of the request. The backoffice is not a daemon. Each backoffice process runs for a short while and then exits. This helps keep Fossil easy to manage, since there are no daemons to start and stop. To upgrade Fossil to a new version, you simply replace the older "fossil" executable with the newer one, and the backoffice processes will (within a minute or so) start using the new one. (Upgrading the executable on Windows is more complicated, since on Windows it is not possible to replace an executable file that is in active use. But Windows users probably already know this.) The backoffice is serialized and rate limited. No more than a single backoffice process will be running at once, and backoffice runs will not occur more frequently than once every 60 seconds. (The 60-second spacing is controlled by the BKOFCE_LEASE_TIME macro in the [backoffice.c](/file/src/backoffice.c) source file.) If a Fossil server is idle, then no backoffice processes will be running. That means there are no extra processes sitting around taking up memory and process table slots for seldom accessed repositories. The backoffice is an on-demand system. A busy repository will usually have a backoffice running at all times. But an infrequently accessed repository will only have backoffice processes running for a minute or two following the most recent access. Manually Running The Backoffice ------------------------------- The automatic backoffice runs are sufficient for most installations. However, the daily digest of email notifications is handled by the backoffice. If a Fossil server can sometimes go more than a day without being accessed, then the automatic backoffice will never run, and the daily digest might not go out until somebody does visit a webpage. If this is a problem, an administrator can set up a cron job to periodically run: > fossil backoffice _REPOSITORY_ That command will cause backoffice processing to occur immediately. Note that this is almost never necessary for an internet-facing Fossil repository, since most repositories will get multiple accesses per day from random robots, which will be sufficient to kick off the daily digest emails. And even for a private server, if there is very little traffic, then the daily digests are probably a no-op anyhow and won't be missed. Automatic Backoffice Does Not Work On Some Systems -------------------------------------------------- We have observed that the automatic backoffice does not work on some system - OpenBSD in particular. We still do not understand why this is. (If you have insights, please share them on the [Fossil Forum](https://fossil-scm.org/forum) so that we can perhaps fix the problem.) For now, the backoffice must be run manually on OpenBSD systems. To set up fully-manual backoffice, first disable the automatic backoffice using the "[backoffice-disable](/help?cmd=backoffice-disable)" setting. > fossil setting backoffice-disable on Then arrange to invoke the backoffice separately using a command like this: > fossil backoffice --poll 30 _REPOSITORY-LIST_ Multiple repositories can be named. This one command will handle launching the backoffice for all of them. There are additional useful command-line options. See the "[fossil backoffice](/help?cmd=backoffice)" documentation for details. The backoffice processes run manually using the "fossil backoffice" command do not normally use a lease. That means that you run the "fossil backoffice" command with --poll and you forget to disable automatic backoffice by setting the "backoffice-disable" flag, then you might have one backoffice running due command and another due to a webpage access, both at the same time. This is harmless. The only downside is that it uses extra CPU time. How Backoffice Is Implemented ----------------------------- The backoffice is implemented by the "[backoffice.c](/file/src/backoffice.c)" source file. Serialization and rate limiting is handled by a single entry in the repository database CONFIG table named "backoffice". This entry is called "the lease". The value of the lease is a text string representing four integers, which are respectively: 1. The process id of the "current" backoffice process 2. The lease expiration time of the current backoffice process 3. The process id of the "next" backoffice process 4. The lease expiration time for the next backoffice process Times are expressed in seconds since 1970. A process id of zero means "no process". Sometimes the process id will be non-zero even if there is no corresponding process. Fossil knows how to figure out whether or not a process still exists. You can print out a decoded copy of the current backoffice lease using this command: > fossil test-backoffice-lease -R _REPOSITORY_ If a system has been idle for a long time, then there will be no backoffice processes. (Either the process id entries in the lease will be zero, or there will exist no process associated with the process id.) When a new web request comes in, the system sees that no backoffice process is active and so it kicks off a separate process to run backoffice. The new backoffice process becomes the "current" process. It sets a lease expiration time for itself to be 60 seconds in the future. Then it does the backoffice processing and exits. Note that usually the backoffice process will exit long before its lease expires. That is ok. The lease is there to limit the rate at which backoffice processes run. If a new backoffice process starts up and sees that the "current" lease has yet to expire, the new process makes itself the "next" backoffice process and sets its expiration time to be 60 seconds past the expiration time of the "current" backoffice process. The "next" process then puts itself to sleep until the "current" lease expires. After the "current" lease expires and the "current" process has itself exited, then the "next" process promotes itself to the new "current" process. It sets the current lease expiration to be 60 seconds in the future, runs whatever backoffice work is needed, then exits. If a new backoffice process starts up and finds that there is already a "current" lease and a "next" process, it exits without doing anything. This should happen only rarely, since the lease information is checked prior to spawning the backoffice process, so a conflict will only happen in a race. Because the "backoffice" entry of the CONFIG table is in the repository database, access to the lease is serialized. The lease prevents more than one backoffice process from running at a time. It prevents backoffice processes from running more frequently than once every 60 seconds. And, it guarantees (assuming processes are not killed out-of-band) that every web request will be followed within 60 seconds by a backoffice run. Debugging The Backoffice ------------------------ The backoffice should "just work". It should not require administrator attention. However, if you suspect that something is not working right, there are some debugging aids. We have already mentioned the command that shows the backoffice lease for a repository: > fossil test-backoffice-lease -R _REPOSITORY_ Running that command every few seconds should show what is going on with backoffice processing in a particular repository. There are also settings that control backoffice behavior. The "backoffice-nodelay" setting prevents the "next" process from taking a lease and sleeping. If "backoffice-nodelay" is set, that causes all backoffice processes to exit either immediately or after doing whatever backoffice works needs to be done. If something is going wrong and backoffice leases are causing delays in webpage processing, then setting "backoffice-nodelay" to true can work around the problem until the bug can be fixed. The "backoffice-logfile" setting is the name of a log file onto which is appended a short message everything a backoffice process actually starts to do the backoffice work. This log file can be used to verify that backoffice really is running, if there is any doubt. The "backoffice-disable" setting prevents automatic backoffice processing, if true. Use this to completely disable backoffice processing that occurs automatically after each HTTP request. The "backoffice-disable" setting does not affect the operation of the manual "fossil backoffice" command. Most installations should leave "backoffice-nodelay" and "backoffice-disable" set to their default values of off and leave "backoffice-logfile" unset or set to an empty string. |

This article overviews the algorithm used to compute the annotation for a file in Fossil. <h2>2.0 Algorithm</h2> <ol type='1'> <li>Locate the check-in that contains the file that is to be annotated. Call this check-in C0. <li>Find all direct ancestors of C0. A direct ancestor is the closure of the primary parent of C0. Merged in branches are not part of the direct ancestors of C0. <li>Prune the list of ancestors of C0 so that it contains only check-in in which the file to be annotated was modified. <li>Load the complete text of the file to be annotated from check-in C0. Call this version of the file F0. <li>Parse F0 into lines. Mark each line as "unchanged". <li>For each ancestor of C0 on the pruned list (call the ancestor CX), beginning with the most recent ancestor and moving toward the oldest ancestor, do the following steps: <ol type='a'> <li>Load the text for the file to be annotated as it existed in check-in CX. Call this text FX. <li>Compute a diff going from FX to F0. <li>For each line of F0 that is changed in the diff and which was previously marked "unchanged", update the mark to indicated that line was modified by CX. </ol> <li>Show each line of F0 together with its change mark, appropriately formatted. </ol> <h2>3.0 Discussion and Notes</h2> The time-consuming part of this algorithm is step 6b - computing the diff from all historical versions of the file to the version of the file under analysis. For a large file that has many historical changes, this can take several seconds. For this reason, the default [/help?cmd=/annotate|/annotate] webpage only shows those lines that where changed by the 20 most recent modifications to the file. This allows the loop on step 6 to terminate after only 19 diffs instead of the hundreds or thousands of diffs that might be required for a frequently modified file. As currently implemented (as of 2015-12-12) the annotate algorithm does not follow files across name changes. File name change information is available in the database, and so the algorithm could be enhanced to follow files across name changes by modifications to step 3. Step 2 is interesting in that it is [/artifact/6cb824a0417?ln=196-201 | implemented] using a [https://www.sqlite.org/lang_with.html#recursivecte|recursive common table expression]. |

Wikipedia defines "blockchain" as > "a growing list of records, called blocks, which are linked using cryptography. Each block contains a cryptographic hash of the previous block, a timestamp, and transaction data..." [(1)][] By that definition, Fossil is clearly an implementation of blockchain. The blocks are ["manifests" artifacts](./fileformat.wiki#manifest). Each manifest has a SHA1 or SHA3 hash of its parent or parents, a timestamp, and other transactional data. The repository grows by adding new manifests onto the list. Some people have come to associate blockchain with cryptocurrency, however, and since Fossil has nothing to do with cryptocurrency, the claim that Fossil is built around blockchain is met with skepticism. The key thing to note here is that cryptocurrency implementations like BitCoin are built around blockchain, but they are not synonymous with blockchain. Blockchain is a much broader concept. Blockchain is a mechanism for constructing a distributed ledger of transactions. Yes, you can use a distributed ledger to implement a cryptocurrency, but you can also use a distributed ledger to implement a version control system, and probably many other kinds of applications as well. Blockchain is a much broader idea than cryptocurrency. [(1)]: https://en.wikipedia.org/wiki/Blockchain |

For the sake of clarity, the check-ins are given small consecutive numbers. In a real system, of course, the check-in numbers would be long hexadecimal hashes since it is not possible to allocate collision-free sequential numbers in a distributed system. But as sequential numbers are easier to read, we will substitute them for the long hashes in this document. The arrows in Figure 1 show the evolution of a project. The initial check-in is 1. Check-in 2 is derived from 1. In other words, check-in 2 was created by making edits to check-in 1 and then committing those edits. We say that 2 is a <i>child</i> of 1 and that 1 is a <i>parent</i> of 2. Check-in 3 is derived from check-in 2, making 3 a child of 2. We say that 3 is a <i>descendant</i> of both 1 and 2 and that 1 and 2 are both <i>ancestors</i> of 3. <h2 id="dag">DAGs</h2> The graph of check-ins is a [http://en.wikipedia.org/wiki/Directed_acyclic_graph | directed acyclic graph], commonly shortened to <i>DAG</i>. Check-in 1 is the <i>root</i> of the DAG since it has no ancestors. Check-in 4 is a <i>leaf</i> of the DAG since it has no descendants. (We will give a more precise definition later of "leaf.") Alas, reality often interferes with the simple linear development of a project. Suppose two programmers make independent modifications to check-in 2. After both changes are committed, the check-in graph looks like Figure 2: <table border=1 cellpadding=10 hspace=10 vspace=10 align="center"> <tr><td align="center"> <img src="branch02.svg"><br> Figure 2 </td></tr></table> The graph in Figure 2 has two leaves: check-ins 3 and 4. Check-in 2 has two children, check-ins 3 and 4. We call this state a <i>fork</i>. Fossil tries to prevent forks, primarily through its "[./concepts.wiki#workflow | autosync]" mechanism. Suppose two programmers named Alice and Bob are each editing check-in 2 separately. Alice finishes her edits and commits her changes first, resulting in check-in 3. When Bob later attempts to commit his changes, Fossil verifies that check-in 2 is still a leaf. Fossil sees that check-in 3 has occurred and aborts Bob's commit attempt with a message "would fork." This allows Bob to do a "fossil update" to pull in Alice's changes, merging them into his own changes. After merging, Bob commits check-in 4 as a child of check-in 3. The result is a linear graph as shown in Figure 1. This is how CVS works. This is also how Fossil works in autosync mode. But perhaps Bob is off-network when he does his commit, so he has no way of knowing that Alice has already committed her changes. Or, it could be that Bob has turned off "autosync" mode in Fossil. Or, maybe Bob just doesn't want to merge in Alice's changes before he has saved his own, so he forces the commit to occur using the "--allow-fork" option to the <b>[/help?cmd=commit | fossil commit]</b> command. For any of these reasons, two commits against check-in 2 have occurred, so the DAG now has two leaves. In such a condition, a person working with this repository has a dilemma: which version of the project is the "latest" in the sense of having the most features and the most bug fixes? When there is more than one leaf in the graph, you don't really know, which is why we would ideally prefer to have linear check-in graphs. Fossil resolves such problems using the check-in time on the leaves to decide which leaf to use as the parent of new leaves. When a branch is forked as in Figure 2, Fossil will choose check-in 4 as the parent for a later check-in 5, but <i>only</i> if it has sync'd that check-in down into the local repository. If autosync is disabled or the user is off-network when that fifth check-in occurs so that check-in 3 is the latest on that branch at the time within that clone of the repository, Fossil will make check-in 3 the parent of check-in 5! We show practical consequences of this [#bad-fork | later in this article]. Fossil also uses a forked branch's leaf check-in timestamps when checking out that branch: it gives you the fork with the latest check-in, which in turn selects which parent your next check-in will be a child of. This situation means development on that branch can fork into two independent lines of development, based solely on which branch tip is newer at the time the next user starts his work on it. Because of these potential problems, we strongly recommend that you do not intentionally create forks on long-lived shared working branches with "--allow-fork". (Prime example: trunk.) The inverse case — intentional forks on short-lived single-developer branches — is far easier to justify, since presumably the lone developer is never confused about why there are two or more leaves on that branch. Further justifications for intentional forking are [#forking | given below]. Let us return to Figure 2. To resolve such situations before they can become a real problem, Alice can use the <b>[/help?cmd=merge | fossil merge]</b> command to merge Bob's changes into her local copy of check-in 3. Without arguments, that command merges all leaves on the current branch. Alice can then verify that the merge is sensible and if so, commit the results as check-in 5. This results in a DAG as shown in Figure 3. <table border=1 cellpadding=10 hspace=10 vspace=10 align="center"> <tr><td align="center"> <img src="branch03.svg"><br> Figure 3 </td></tr></table> Check-in 5 is a child of check-in 3 because it was created by editing check-in 3, but since check-in 5 also inherits the changes from check-in 4 by virtue of the merge, we say that check-in 5 is a <i>merge child</i> of check-in 4 and that it is a <i>direct child</i> of check-in 3. The graph is now back to a single leaf, check-in 5. We have already seen that if Fossil is in autosync mode then Bob would have been warned about the potential fork the first time he tried to commit check-in 4. If Bob had updated his local check-out to merge in Alice's check-in 3 changes, then committed, the fork would have never occurred. The resulting graph would have been linear, as shown in Figure 1. Realize that the graph of Figure 1 is a subset of Figure 3. If you hold your hand over the ④ in Figure 3, it looks exactly like Figure 1 except that the leaf has a different check-in number. That is just a notational difference: the two check-ins have exactly the same content. Inversely, Figure 3 is a superset of Figure 1. The check-in 4 of Figure 3 captures additional state which is omitted from Figure 1. Check-in 4 of Figure 3 holds a copy of Bob's local checkout before he merged in Alice's changes. That snapshot of Bob's changes, which is independent of Alice's changes, is omitted from Figure 1. Some people say that the development approach taken in Figure 3 is better because it preserves this extra intermediate state. Others say that the approach taken in Figure 1 is better because it is much easier to visualize linear development and because the merging happens automatically instead of as a separate manual step. We will not take sides in that debate. We will simply point out that Fossil enables you to do it either way. <h2 id="branching">The Alternative to Forking: Branching</h2> Having more than one leaf in the check-in DAG is called a "fork." This is usually undesirable and either avoided entirely, as in Figure 1, or else quickly resolved as shown in Figure 3. But sometimes, one does want to have multiple leaves. For example, a project might have one leaf that is the latest version of the project under development and another leaf that is the latest version that has been tested. When multiple leaves are desirable, we call this <i>branching</i> instead of <i>forking</i>: Figure 4 shows an example of a project where there are two branches, one for development work and another for testing. <table border=1 cellpadding=10 hspace=10 vspace=10 align="center"> <tr><td align="center"> <img src="branch04.svg"><br> Figure 4 </td></tr></table> Figure 4 diagrams the following scenario: the project starts and progresses to a point where (at check-in 2) it is ready to enter testing for its first release. In a real project, of course, there might be hundreds or thousands of check-ins before a project reaches this point, but for simplicity of presentation we will say that the project is ready after check-in 2. The project then splits into two branches that are used by separate teams. The testing team, using the blue branch, finds and fixes a few bugs with check-ins 6 and 9. Meanwhile, the development team, working on the top uncolored branch, is busy adding features for the second release. Of course, the development team would like to take advantage of the bug fixes implemented by the testing team, so periodically the changes in the test branch are merged into the dev branch. This is shown by the dashed merge arrows between check-ins 6 and 7 and between check-ins 9 and 10. In both Figures 2 and 4, check-in 2 has two children. In Figure 2, we call this a "fork." In diagram 4, we call it a "branch." What is the difference? As far as the internal Fossil data structures are concerned, there is no difference. The distinction is in the intent. In Figure 2, the fact that check-in 2 has multiple children is an accident that stems from concurrent development. In Figure 4, giving check-in 2 multiple children is a deliberate act. To a good approximation, we define forking to be by accident and branching to be by intent. Apart from that, they are the same. When the fork is intentional, it helps humans to understand what is going on if we <i>name</i> the forks. This is not essential to Fossil's internal data model, but humans have trouble working with long-lived branches identified only by the commit ID currently at its tip, being a long string of hex digits. Therefore, Fossil conflates two concepts: branching as intentional forking and the naming of forks as branches. They are in fact separate concepts, but since Fossil is intended to be used primarily by humans, we combine them in Fossil's human user interfaces. <blockquote> <b>Key Distinction:</b> A branch is a <i>named, intentional</i> fork. </blockquote> Unnamed forks <i>may</i> be intentional, but most of the time, they're accidental and left unnamed. Fossil offers two primary ways to create named, intentional forks, a.k.a. branches. First: <pre> $ fossil commit --branch my-new-branch-name </pre> This is the method we recommend for most cases: it creates a branch as part of a check-in using the version in the current checkout directory as its basis. (This is normally the tip of the current branch, though it doesn't have to be. You can create a branch from an ancestor check-in on a branch as well.) After making this branch-creating check-in, your local working directory is switched to that branch, so that further check-ins occur on that branch as well, as children of the tip check-in on that branch. The second, more complicated option is: <pre> $ fossil branch new my-new-branch-name trunk $ fossil update my-new-branch-name $ fossil commit </pre> Not only is this three commands instead of one, the first of which is longer than the entire simpler command above, you must give the second command before creating any check-ins, because until you do, your local working directory remains on the same branch it was on at the time you issued the command, so that the commit would otherwise put the new material on the original branch instead of the new one. In addition to those problems, the second method is a violation of the [https://en.wikipedia.org/wiki/You_aren%27t_gonna_need_it|YAGNI Principle]. We recommend that you wait until you actually need the branch before you create it using the first command above. The "trunk" is just another named branch in Fossil. It is simply the default branch name for the first check-in and every check-in made as one of its direct descendants. It is special only in that it is Fossil's default when it has no better idea of which branch you mean. <h2 id="forking">Justifications For Forking</h2> The primary cases where forking is justified over branching are all when it is done purely in software in order to avoid losing information: <ol> <li><p id="offline">By Fossil itself when two users check in children to the same leaf of a branch, as in Figure 2. <br><br> If the fork occurs because autosync is disabled on one or both of the repositories or because the user doing the check-in has no network connection at the moment of the commit, Fossil has no way of knowing that it is creating a fork until the two repositories are later synchronized.</p></li> <li><p id="dist-clone">By Fossil when the cloning hierarchy is more than 2 levels deep. <br><br> [./sync.wiki|Fossil's synchronization protocol] is a two-party negotiation; syncs don't automatically propagate up the clone tree beyond that. Because of that, if you have a master repository and Alice clones it, then Bobby clones from Alice's repository, a check-in by Bobby that autosyncs with Alice's repo will <i>not</i> also autosync with the master repo. The master doesn't get a copy of Bobby's check-in until Alice <i>separately</i> syncs with the master. If Carol cloned from the master repo and checks something in that creates a fork relative to Bobby's check-in, the master repo won't know about that fork until Alice syncs her repo with the master. Even then, realize that Carol still won't know about the fork until she subsequently syncs with the master repo. <br><br> One way to deal with this is to just accept it as a fact of using a [https://en.wikipedia.org/wiki/Distributed_version_control|Distributed Version Control System] like Fossil. <br><br> Another option, which we recommend you consider carefully, is to make it a local policy that check-ins be made only directly against the master repo or one of its immediate child clones so that the autosync algorithm can do its job most effectively. Any clones deeper than that should be treated as read-only and thus get a copy of the new state of the world only once these central repos have negotiated that new state. This policy avoids a class of inadvertent fork you might not need to tolerate. Since [#bad-fork|forks on long-lived shared working branches can end up dividing a team's development effort], a team may easily justify this restriction on distributed cloning.</p></li> <li><p id="automation">You've automated Fossil, so you use <b>fossil commit --allow-fork</b> commands to prevent Fossil from refusing the check-in simply because it would create a fork. <br><br> If you are writing such a tool — e.g. a shell script to make multiple manipulations on a Fossil repo — it's better to make it smart enough to detect this condition and cope with it, such as by making a call to <b>[/help?cmd=update | fossil update]</b> and checking for a merge conflict. That said, if the alternative is losing information, you may feel justified in creating forks that an interactive user must later manually clean up with <b>fossil merge</b> commands.</p></li> </ol> That leaves only one case where we can recommend use of "--allow-fork" by interactive users: when you're working on a personal branch so that creating a dual-tipped branch isn't going to cause any other user an inconvenience or risk [#bad-fork | inadvertently forking the development effort]. In such a case, the lone developer working on that branch is not confused, since the fork in development is intentional. Sometimes it simply makes no sense to bother creating a name, cluttering the global branch namespace, simply to convert an intentional fork into a "branch." This is especially the case when the fork is short-lived. There's a common generalization of that case: you're a solo developer, so that the problems with branching vs forking simply don't matter. In that case, feel free to use "--allow-fork" as much as you like. <h2 id="fix">Fixing Forks</h2> If your local checkout is on a forked branch, you can usually fix a fork automatically with: <pre> $ fossil merge </pre> Normally you need to pass arguments to <b>fossil merge</b> to tell it what you want to merge into the current basis view of the repository, but without arguments, the command seeks out and fixes forks. <h2 id="tags">Tags And Properties</h2> Tags and properties are used in Fossil to help express the intent, and thus to distinguish between forks and branches. Figure 5 shows the same scenario as Figure 4 but with tags and properties added: <table border=1 cellpadding=10 hspace=10 vspace=10 align="center"> <tr><td align="center"> <img src="branch05.svg"><br> Figure 5 </td></tr></table> A <i>tag</i> is a name that is attached to a check-in. A <i>property</i> is a name/value pair. Internally, Fossil implements tags as properties with a NULL value. So, tags and properties really are much the same thing, and henceforth we will use the word "tag" to mean either a tag or a property. A tag can be a one-time tag, a propagating tag or a cancellation tag. A one-time tag only applies to the check-in to which it is attached. A propagating tag applies to the check-in to which it is attached and also to all direct descendants of that check-in. A <i>direct descendant</i> is a descendant through direct children. Tag propagation does not cross merges. Tag propagation also stops as soon as it encounters another check-in with the same tag. A cancellation tag is attached to a single check-in in order to either override a one-time tag that was previously placed on that same check-in, or to block tag propagation from an ancestor. The initial check-in of every repository has two propagating tags. In Figure 5, that initial check-in is check-in 1. The <b>branch</b> tag tells (by its value) what branch the check-in is a member of. The default branch is called "trunk." All tags that begin with "<b>sym-</b>" are symbolic name tags. When a symbolic name tag is attached to a check-in, that allows you to refer to that check-in by its symbolic name rather than by its hexadecimal hash name. When a symbolic name tag propagates (as does the <b>sym-trunk</b> tag) then referring to that name is the same as referring to the most recent check-in with that name. Thus the two tags on check-in 1 cause all descendants to be in the "trunk" branch and to have the symbolic name "trunk." Check-in 4 has a <b>branch</b> tag which changes the name of the branch to "test." The branch tag on check-in 4 propagates to check-ins 6 and 9. But because tag propagation does not follow merge links, the <b>branch=test</b> tag does not propagate to check-ins 7, 8, or 10. Note also that the <b>branch</b> tag on check-in 4 blocks the propagation of <b>branch=trunk</b> so that it cannot reach check-ins 6 or 9. This causes check-ins 4, 6, and 9 to be in the "test" branch and all others to be in the "trunk" branch. Check-in 4 also has a <b>sym-test</b> tag, which gives the symbolic name "test" to check-ins 4, 6, and 9. Because tags do not propagate across merges, check-ins 7, 8, and 10 do not inherit the <b>sym-test</b> tag and are hence not known by the name "test." To prevent the <b>sym-trunk</b> tag from propagating from check-in 1 into check-ins 4, 6, and 9, there is a cancellation tag for <b>sym-trunk</b> on check-in 4. The net effect is that check-ins on the trunk go by the symbolic name of "trunk" and check-ins on the test branch go by the symbolic name "test." The <b>bgcolor=blue</b> tag on check-in 4 causes the background color of timelines to be blue for check-in 4 and its direct descendants. Figure 5 also shows two one-time tags on check-in 9. (The diagram does not make a graphical distinction between one-time and propagating tags.) The <b>sym-release-1.0</b> tag means that check-in 9 can be referred to using the more meaningful name "release-1.0." The <b>closed</b> tag means that check-in 9 is a "closed leaf." A closed leaf is a leaf that should never have direct children. <h2 id="bad-fork">How Can Forks Divide Development Effort?</h2> [#dist-clone|Above], we stated that forks carry a risk that development effort on a branch can be divided among the forks. It might not be immediately obvious why this is so. To see it, consider this swim lane diagram: <table border=1 cellpadding=10 hspace=10 vspace=10 align="center"> <tr><td align="center"> <img src="branch06.svg"><br> Figure 6 </td></tr></table> This is a happy, cooperating team. That is an important restriction on our example, because you must understand that this sort of problem can arise without any malice, selfishness, or willful ignorance in sight. All users on this diagram start out with the same view of the repository, cloned from the same master repo, and all of them are working toward their shared vision of a unified future. All users, except possibly Alan, start out with the same two initial check-ins in their local working clones, 1 & 2. It might be that Alan starts out with only check-in 1 in his local clone, but we'll deal with that detail later. It doesn't matter which branch this happy team is working on, only that our example makes the most sense if you think of it as a long-lived shared working branch like trunk. Each user makes only one check-in, shaded light gray in the diagram. <h3 id="bf-alan">Step 1: Alan</h3> Alan sets the stage for this problem by creating a fork from check-in 1 as check-in 3. How and why Alan did this doesn't affect what happens next, though we will walk through the possible cases and attempt to assign blame [#post-mortem|in the <i>post mortem</i>]. For now, you can assume that Alan did this out of unavoidable ignorance. <h3 id="bf-betty">Step 2: Betty</h3> Because Betty's local clone is autosyncing with the same upstream repository as Alan's clone, there are a number of ways she can end up seeing Alan's check-in 3 as the latest on that branch: <ol> <li><p>The working check-out directory she's using at the moment was on a different branch at the time Alan made check-in 3, so Fossil sees that as the tip at the time she switches her working directory to that branch with a <b>fossil update $BRANCH</b> command. (There is an implicit autosync in that command, if the option was enabled at the time of the update.)</p></li> <li><p>The same thing, only in a fresh checkout directory with a <b>[/help?cmd=open | fossil open $REPO $BRANCH]</b> command.</p></li> <li><p>Alan makes his check-in 3 while Betty has check-in 1 or 2 as the tip in her local clone, but because she's working with an autosync'd connection to the same upstream repository as Alan, on attempting what will become check-in 4, she gets the "would fork" message from <b>fossil commit</b>, so she dutifully updates her clone and tries again, moving her work to be a child of the new tip, check-in 3. (If she doesn't update, she creates a <i>second</i> fork, which simply complicates matters beyond what we need here for our illustration.)</p></li> </ol> For our purposes here, it doesn't really matter which one happened. All that matters is that Alan's check-in 3 becomes the parent of Betty's check-in 4 because it was the newest tip of the working branch at the time Betty does her check-in. <h3 id="bf-charlie">Step 3: Charlie</h3> Meanwhile, Charlie went offline after syncing his repo with check-in 2 as the latest on that branch. When he checks his changes in, it is as a child of 2, not of 4, because Charlie doesn't know about check-ins 3 & 4 yet. He does this at an absolute wall clock time <i>after</i> Alan and Betty made their check-ins, so when Charlie comes back online and pushes his check-in 5 to the master repository and learns about check-ins 3 and 4 during Fossil sync, Charlie inadvertently revives the other side of the fork. <h3 id="bf-darlene">Step 4: Darlene</h3> Darlene sees all of this, because she joins in on the work on this branch after Alan, Betty, and Charlie made their check-ins and pushed them to the master repository. She's taking one of the same three steps as we [#bf-betty|outlined for Betty above]. Regardless of her path to this view, it happens after Charlie pushed his check-in 5 to the master repo, so Darlene sees that as the latest on the branch, causing her work to be saved as a child of check-in 5, not of check-in 4, as it would if Charlie didn't come back online and sync before Darlene started work on that branch. <h3 id="post-mortem">Post Mortem</h3> The end result of all of this is that even though everyone makes only one check-in and no one disables autosync without genuine need, half of the check-ins end up on one side of the fork and half on the other. A future user — his mother calls him Edward, but please call him Eddie — can then join in on the work on this branch and end up on <i>either</i> side of the fork. If Eddie joins in with the state of the repository as drawn above, he'll end up on the top side of the fork, because check-in 6 is the latest, but if Alan or Betty makes a seventh check-in to that branch first, it will be as a child of check-in 4 since that's the version in their local check-out directories. Since that check-in 7 will then be the latest, Eddie will end up on the bottom side of the fork instead. In all of this, realize that neither side of the fork is obviously "correct." Every participant was doing the right thing by their own lights at the time they made their lone check-in. Who, then, is to blame? We can only blame the consequences of creating the fork on Alan if he did so on purpose, as by passing "--allow-fork" when creating a check-in on a shared working branch. Alan might have created it inadvertently by going offline while check-in 1 was the tip of the branch in his local clone, so that by the time he made his check-in 3, check-in 2 had arrived at the shared parent repository from someone else. (Francine?) When Alan rejoins the network and does an autosync, he learns about check-in 2. Since his #3 is already checked into his local clone because autosync was off or blocked, the sync creates an unavoidable fork. We can't blame either Alan or Francine here: they were both doing the right thing given their imperfect view of the state of the global situation. The same is true of Betty, Charlie, and Darlene. None of them tried to create a fork, and none of them chose a side in this fork to participate in. They just took Fossil's default and assumed it was correct. The only blame I can assign here is on any of these users who believed forks couldn't happen before this did occur, and I blame them only for their avoidable ignorance. (You, dear reader, have been ejected from that category by reading this very document.) Any time someone can work without getting full coordination from every other clone of the repo, forks are possible. Given enough time, they're all but inevitable. This is a general property of DVCSes, not just of Fossil. This sort of consequence is why forks on shared working branches are bad, which is why [./concepts.wiki#workflow|Fossil tries so hard to avoid them], why it warns you about it when they do occur, and why it makes it relatively [#fix|quick and painless to fix them] when they do occur. <h2>Review Of Terminology</h2> <blockquote><dl> <dt><b>Branch</b></dt> <dd><p>A branch is a set of check-ins with the same value for their "branch" property.</p></dd> <dt><b>Leaf</b></dt> <dd><p>A leaf is a check-in with no children in the same branch.</p></dd> <dt><b>Closed Leaf</b></dt> <dd><p>A closed leaf is any leaf with the <b>closed</b> tag. These leaves are intended to never be extended with descendants and hence are omitted from lists of leaves in the command-line and web interface.</p></dd> <dt><b>Open Leaf</b></dt> <dd><p>A open leaf is a leaf that is not closed.</p></dd> <dt><b>Fork</b></dt> <dd><p>A fork is when a check-in has two or more direct (non-merge) children in the same branch.</p></dd> <dt><b>Branch Point</b></dt> <dd><p>A branch point occurs when a check-in has two or more direct (non-merge) children in different branches. A branch point is similar to a fork, except that the children are in different branches.</p></dd> </dl></blockquote> Check-in 4 of Figure 3 is not a leaf because it has a child (check-in 5) in the same branch. Check-in 9 of Figure 5 also has a child (check-in 10) but that child is in a different branch, so check-in 9 is a leaf. Because of the <b>closed</b> tag on check-in 9, it is a closed leaf. Check-in 2 of Figure 3 is considered a "fork" because it has two children in the same branch. Check-in 2 of Figure 5 also has two children, but each child is in a different branch, hence in Figure 5, check-in 2 is considered a "branch point." <h2>Differences With Other DVCSes</h2> <h3 id="single">Single DAG</h3> Fossil keeps all check-ins on a single DAG. Branches are identified with tags. This means that check-ins can be freely moved between branches simply by altering their tags. Most other DVCSes maintain a separate DAG for each branch. <h3 id="unique">Branch Names Need Not Be Unique</h3> Fossil does not require that branch names be unique, as in some VCSes, most notably Git. Just as with unnamed branches (which we call forks) Fossil resolves such ambiguities using the timestamps on the latest check-in in each branch. If you have two branches named "foo" and you say <b>fossil update foo</b>, you get the tip of the "foo" branch with the most recent check-in. This fact is helpful because it means you can reuse branch names, which is especially useful with utility branches. There are several of these in the SQLite and Fossil repositories: "broken-build," "declined," "mistake," etc. As you might guess from these names, such branch names are used in renaming the tip of one branch to shunt it off away from the mainline of that branch due to some human error. (See <b>[/help?cmd=amend | fossil amend]</b> and the Fossil UI check-in amendment features.) This is a workaround for Fossil's [./shunning.wiki|normal inability to forget history]: we usually don't want to actually <i>remove</i> history, but would like to sometimes set some of it aside under a new label. Because some VCSes can't cope with duplicate branch names, Fossil collapses such names down on export using the same time stamp based arbitration logic, so that only the branch with the newest check-in gets the branch name in the export. All of the above is true of tags in general, not just branches. |

Additionally, source archives of <em>released</em> versions of fossil are available from the [/uv/download.html|downloads page]. To obtain a development version of fossil, follow these steps:</p> <ol> <li><p>Point your web browser to [https://www.fossil-scm.org/]</li> <li><p>Click on the [/timeline|Timeline] link at the top of the page.</p></li> <li><p>Select a version of of Fossil you want to download.

Any check-in on the [/timeline?t=trunk | trunk branch] of the Fossil [http://fossil-scm.org/fossil/timeline | Fossil self-hosting repository] will work fine. (Dodgy code is always on a branch.) In the unlikely event that you pick a version with a serious bug, it still won't clobber your files. Fossil uses several [./selfcheck.wiki | self-checks] prior to committing any repository change that prevent loss-of-work due to bugs. The Fossil [./selfhost.wiki | self-hosting repositories], especially the one at [http://www.fossil-scm.org/fossil], usually run a version of trunk that is less than a week or two old. Look at the bottom left-hand corner of this screen (to the right of "This page was generated in...") to see exactly which version of Fossil is rendering this page. It is always safe to use whatever version of the Fossil code you find running on the main Fossil website. <h2>2.0 Compiling</h2> <ol> <li value="5"> <p>Unpack the ZIP or tarball you downloaded then <b>cd</b> into the directory created.</p></li> <li><i>(Optional, Debian-compatible Linux only)</i> Make sure you have all the necessary tools and libraries at hand by running: <b>sudo apt install tcl-dev tk libssl-dev</b>. <li><i>(Optional, Unix only)</i> Run <b>./configure</b> to construct a makefile. <ol type="a"> <li><p> The build system for Fossil on Unix-like systems assumes that the OpenSSL development and runtime files are available on your system, because unprotected repositories are trivial to attack otherwise.

That can be worked around by building against a different C library, which is simplest to do by way of a container environment like [https://www.docker.com/ | Docker]. The following instructions for building fossil using Docker were adapted from [https://fossil-scm.org/forum/forumpost/5dd2d61e5f | forumpost/5dd2d61e5f]. These instructions assume that docker is installed and that the user running these instructions has permission to do so (i.e., they are <tt>root</tt> or are a member of the <tt>docker</tt> group). First, create a file named <tt>Dockerfile</tt> with the following contents: <pre><code> FROM alpine:edge RUN apk update \ && apk upgrade \ \ && apk add --no-cache \ curl gcc make tcl \ musl-dev \ openssl-dev zlib-dev \ openssl-libs-static zlib-static \ \ && curl \ "https://www.fossil-scm.org/index.html/tarball/fossil-src.tar.gz?name=fossil-src&uuid=trunk" \ -o fossil-src.tar.gz \ \ && tar xf fossil-src.tar.gz \ && cd fossil-src \ \ && ./configure \ --static \ --disable-fusefs \ --with-th1-docs \ --with-th1-hooks \ \ && make </code></pre> Be sure to modify the <tt>configure</tt> flags, if desired. e.g., add <tt>--json</tt> for JSON support. From the directory containing that file, build it with docker: <pre><code># docker build -t fossil_static .</code></pre> If you get permissions errors when running that as a non-root user, be sure to add the user to the <tt>docker</tt> group before trying again. That creates a docker image and builds a static fossil binary inside it. That step will take several minutes or more, depending on the speed of the build environment. Next, create a docker container to host the image we just created: <pre><code># docker create --name fossil fossil_static</code></pre> Then copy the fossil binary from that container: <pre><code># docker cp fossil:/fossil-src/fossil fossil</code></pre> The resulting binary will be <em>huge</em> because it is built with debug info. To strip that information, reducing the size greatly: <pre><code># strip fossil</code></pre> To delete the Docker container and image (if desired), run: <pre><code># docker container rm fossil # docker image ls </code></pre> Note the IDs of the images named <tt>fossil_static</tt> and <tt>alpine</tt>, then: <pre><code>docker image rm THE_FOSSIL_ID THE_ALPINE_ID</code></pre> <h2>6.0 Building on/for Android</h2> <h3>6.1 Cross-compiling from Linux</h3> The following instructions for building Fossil for Andoid, without requiring a rooted OS, are adapted from [https://fossil-scm.org/forum/forumpost/e0e9de4a7e | forumpost/e0e9de4a7e].

However, IDE may be useful in development of the Fossil code. Staple IDE features that come to mind are ease of editing, static code analysis, source indexing, autocomplete, and integrated debugging. Who may benefit from using an IDE? In general sense, of course, anyone who is used to a particular IDE. Specifically to Fossil development this could be: * Developers who are __new to Fossil code__; IDE helps navigate definitions and implementations across the source files * Developers who may be familiar with the code, yet would want to diagnose an issue that calls for __in-depth debugging__; IDE makes debugging somewhat more accessible [Current Fossil build process](./makefile.wiki) is Makefile-based, which extensively uses code-generation. It's flexible, yet as such it's not natively fitting any specific IDE. This often represents a challenge for an IDE workflow as it's trying to figure out the correct dependencies. To assist with Fossil IDE workflow, there're currently two alternatives to consider depending on IDE capabilities to support it: * [Use CMake-based workflow](#cmake-workflow); in this case the Fossil's [CMakeLists.txt](/file/CMakeLists.txt) file is directly used as the IDE project file * [Import the existing Makefile](#import-makefile) and then tweak the resulting project settings to properly reference the dependencies The following sections describe both approaches as tested with a selection of IDEs (not exhaustive). > __USAGE NOTES__: To get most utility out of IDE in Fossil development, it's > recommended to do a general development in _Release_ build configuration. > In this case, compile errors would refer to original source files instead > of the generated ones which actually get compiled.

So far the Fossil CMake-based workflow has been tried with the following IDEs: * [Qt Creator](#cmake-qtc) (Linux, Windows) * [VisualStudio 2017](#cmake-vs) (Windows) * [Eclipse CDT](#cmake-eclipse) (Linux) * [VSCode](#cmake-vscode) (Linux, Windows) * [Code::Blocks](#cmake-cb) (Linux) <a name="cmake-cmd"></a> __Using CMake on the Command-line__ In general, the CMake workflow is very much the same on all of the supported platforms. CMake generator takes care of the platform/compiler specifics. CMake can be used directly on the command-line to build the Fossil project in either Release or Debug configuration: cd fossil mkdir build-debug cd build-debug cmake .. -G"Unix Makefiles" -DCMAKE_BUILD_TYPE=Debug make OR on Windows with MSVC: cmake .. -G"NMake Makefiles" -DCMAKE_BUILD_TYPE=Debug nmake An IDE executes similar commands behind the scenes to generate and build a CMake-based project. In general, CMake is capable of generating native project files for a wide selection of IDEs. However for the Fossil CMake project, it's preferable to generate a __Makefiles__ build system, because that's what the underlying Fossil build process is. Below are the steps used to setup Fossil CMake project in the IDEs tested. > __NOTE__: To refresh a _Project Tree View_ so that it shows the generated > files, the easiest way is to re-save the `CMakeLists.txt` file. This > triggers the IDE tools to regenerate the build system and rescan the project > source files. <a name="cmake-qtc"></a> __Qt Creator__ CMake workflow in Qt Creator has been supported for quite some time, so it evolved to become more streamlined. Below are the steps to set up CMake project in Qt Creator version 4.5 and above. 1. From Weclome panel _Open Project_, browse to the Fossil project directory and open the `CMakeLists.txt` file. 1. Qt Creator will prompt to select a _Kit_ to configure the project. For example, `Desktop Qt 5.9.4 GCC 64bit` At this point the project is already usable. Optionally, for convenience it makes sense to adjust some of the default settings. 1. Open the _Projects_ panel 1. Remove the extra build configurations, keep Debug and Release 1. For each of the build configurations * Select a _Build directory_. For example: `build-fossil-debug/` directory or `build-debug/` subdirectory. * Set any additional CMake variables Now it's ready for build and use. 1. Select the build configuration; for example `Debug` 1. Do _Build Project "fossil"_; it runs the CMake and then starts the build showing the progress in the _Compile Output_ pane 1. Refresh the _Projects Explorer View_ so that it shows the generated files: * Open the `CMakeLists.txt` file and trivially "touch" it then re-save it. * This triggers CMake which then re-populates the _Project Explorer View_ adding the generated header files from the build directory. 1. Navigate definitions/implementations. For example, in `src/main.c` function `version_cmd()` for the function `fossil_print()` select context menu _Follow Symbol Under Cursor_ -- the Fossil source file `src/printf.c` automatically opens in editor. 1. Set the run arguments -- panel _Projects: Run_; by default the `app` target is already selected (`bin/fossil` executable): * Set the _Command line arguments:_ for example, `version` * Optionally, check _Run in terminal_ 1. Do _Run_ OR 1. To start debugging -- do menu _Debug> Step Into_; the editor opens file `main_.c` (generated!!), execution stops in `main()`. Fossil executable output is shown in a separate terminal window. > __WARNING__: Edits to _generated_ files in the build directory will __NOT__ > survive a _Rebuild_, and the changes cannot be committed directly to the > project repository. > > Make sure you edit files in the Fossil __source__ directories. <a name="cmake-vs"></a> __Visual Studio 2017__ Starting with Visual Studio 2017 CMake-based projects (`CMakeLists.txt` files) are directly supported without the need to generate an intermediate MSBuild project files. This feature is supported via _Visual C++ Tools for CMake_ component which is installed by default as part of the __Desktop development with C++__ workload. > __NOTE__: By default, Visual Studio 2017 CMake Tools uses Ninja build tool. > In general it has a better performance over the usual NMake, as it allows > parallel build tasks. However in the scope of Fossil CMake project there's > no real speedup, since the underlying Fossil Makefile is still built with > NMake. > > As Ninja tool has some subtle differences in handling of the `clean` target, > it's recommended to select the `"NMake Makefiles"` generator for the Fossil > CMake project (which is a valid choice despite a possible warning.) 1. Menu _File> Open:Folder_ to open Fossil source project directory that contains the `CMakeLists.txt` file 1. Change the generator -- menu _CMake> Change CMake Settings> fossil_ will open `CMakeSettings.json` file; in all of the defined configurations set: "generator": "NMake Makefiles", "buildCommandArgs": "", Save the settings file and the project is reconfigured automatically. 1. Select configuration -- toolbar _Select Project Settings_, for example: `x64-Debug` 1. Do menu _CMake> Build All_; build progress is shown in _Output:Build_ pane 1. Navigate definitions/implementations. For example, in `src/main.c` function `version_cmd()` for the function `fossil_print()` select context menu _Peek Definition_ -- the Fossil source file `src/printf.c` automatically opens the peek preview pane. 1. Select a start target `bin/fossil.exe` -- toolbar _Select Startup Item_ 1. Set the run arguments -- menu _CMake> Debug and Launch Settings_ in the file `.vs/launch.vs.json`. For example, for _"default"_ configuration append: "args": ["version"] Save the settings file. 1. To start debugging -- do menu _Debug> Step Into_; the editor opens file `main_.c` (generated!!), execution stops in `main()`. Fossil executable output is shown in a separate terminal window. > __WARNING__: Edits to _generated_ files in the build directory will __NOT__ > survive a _Rebuild_, and the changes cannot be committed directly to the > project repository. > > Make sure you edit files in the Fossil __source__ directories. > __NOTE__: If doing a cross-platform build, it's necessary to clean the > builds of the external components that are used with Fossil (in `compat/` > subdirectory). For example, `zlib`, `openssl`. Failure to do that may > manifest with the fireworks of compile and link errors. <a name="cmake-eclipse"></a> __Eclipse CDT__ To configure CMake-based project with Eclipse it first has to be generated as a native project, then imported into Eclipse as an existing project. The CMake build directory should __not__ be a subdirectory of the Fossil project source directory, but rather a sibling or other directory. For example: workspace/ |-- fossil-debug/ <== CMake build directory |-- fossil/ <== Fossil project directory | `-- CMakeLists.txt `-- fossil-release/ 1. Generate Eclipse CDT4 makefiles, optionally specify the Eclipse's version: cd workspace cd debug cmake ../fossil -G"Eclipse CDT4 - Unix Makefiles" -DCMAKE_BUILD_TYPE=Debug -DCMAKE_ECLIPSE_VERSION=3.8 ls .cproject 1. From Eclipse do _Import_ as a _General>Existing Projects into Workspace_ from within the CMake build directory. This pulls both the Fossil CMake-based project and the original Makefiles-based project which appears under _[Subprojects]/fossil_ 1. Do _Build_ and then menu _Project> C/C++ Index: Rebuild_ to pick up the generated sources needed for the code browsing and autocomplete 1. Navigate definitions/implementations. For example, in `src/main.c` function `version_cmd()` hover mouse over the call to `fossil_print()` -- this allows to peek at its implementation. Or select _Open Declaration_ from the context menu. 1. For running and debugging, create a new _Run:Run Configuration_ for _C/C++ Application_; name it `fossil`, pick a project executable `bin/fossil` and specify run arguments. For example: `version` 1. Do _Debug fossil_, which would switch to the Debug perspective and the editor opens file `main_.c` (generated!!), execution stops in `main()` > __WARNING__: Edits to _generated_ files in the build directory will __NOT__ > survive a _Rebuild_, and the changes cannot be committed directly to the > project repository. > > Make sure you edit files in the Fossil __source__ directories. > __NOTE__: Eclipse creates a few local files and folders to keep its settings, > (namely `.project`) which may already be part of Fossil, so make sure not to > push them to the main Fossil repository. <a name="cmake-vscode"></a> __VSCode__ If you're a regular VSCode user, you probably have all the needed C/C++ and CMake extensions already installed and set up. Otherwise, C/C++ and CMake extensions need to be installed from the marketplace to enable CMake support. For example: 1. _C/C++_ ("C/C++", ms-vscode.cpptools) 1. _CMake Tools_ ("CMake Tools") 1. _CMake_ ("CMake For VisualStudio Code") Then you may follow the CMake Tools "Getting Started" guide skipping to "Configuring Your Project" section. It's also helpful to review "C/C++" extension documentation for "Configuring launch.json for C/C++ debugging". Briefly: 1. Open the Fossil source project folder in VSCode: cd fossil code . 1. _CMake Tools_ extension notification prompts to configure your project 1. Select a _Kit_ from the shown list. For example, `GCC` 1. _CMake Tools_ then executes CMake commands and by default configures the project to build in `build/` subdirectory with Debug configuration. 1. In status bar set active target `app` (it's set to `[all]` by default) 1. Build the project -- status-bar command _Build_ 1. Navigate definitions/implementations. For example, in `src/main.c` function `version_cmd()` for the function `fossil_print()` select context menu _Peek Definition_ -- the Fossil source file `src/printf.c` automatically opens the peek preview pane. 1. Set the run arguments -- menu _Debug:Open Configurations_ for C/C++ in the file `.vscode/launch.json`. For example, for _"(gdb) Launch"_ configuration add: "program": "${workspaceFolder}/build/bin/fossil", "args": ["version"], "stopAtEntry": true, "cwd": "${workspaceFolder}/build", Save the file. 1. Switch to the Debug view and _Start Debugging_; the editor opens file `main_.c` (generated!!), execution stops in `main()` > __WARNING__: Edits to _generated_ files in the build directory will __NOT__ > survive a _Rebuild_, and the changes cannot be committed directly to the > project repository. > > Make sure you edit files in the Fossil __source__ directories. <a name="cmake-cb"></a> __Code::Blocks__ 1. Create a build directory 1. Generate the Code::Blocks project from the Fossil `CMakeLists.txt` file: mkdir build-debug cd build-debug cmake .. -G"CodeBlocks - Unix Makefiles" -DCMAKE_BUILD_TYPE=Debug ls fossil.cbp 1. Open the generated Code::Blocks project `.cbp` file 1. Select and build `app` target (_Logs_ view shows _Build log_ output) 1. Re-run the CMake command to refresh the project tree so it shows the generated source/include files: cmake .. 1. Navigate source for definitions/implementations. For example, in `src/main.c` function `version_cmd()` find the implementation of `fossil_print()` -- the Fossil source file `src/printf.c` automatically opens in editor to show the function body. 1. Set the run arguments -- menu _Project:Set program's arguments_ for target `app`. For example: `version` 1. _Run_; OR 1. For debugging select Menu _Debug:Step-in_; the editor opens file `main_.c` (generated!!), execution stops in `main()` > __WARNING__: Edits to _generated_ files in the build directory will __NOT__ > survive a _Rebuild_, and the changes cannot be committed directly to the > project repository. > > Make sure you edit files in the Fossil __source__ directories. <a name="import-makefile"></a> Import the Existing Fossil Makefile ----------------------------------- Many IDEs allow importing an existing Makefile based project. However, not all Makefiles are equally straightforward to import. Fossil's build process involves quite extensive use of code-generation, which complicates dependency resolution. The resulting IDE project file may turn up not very practical. Additionally, such an imported project will need to be maintained manually or re-imported to account for upstream updates in the Fossil project (additions, renames etc.) On the plus side, once the resulting Fossil IDE project has been configured, it's as close to the original Makefile as it could be. Chances are the bulk of dependencies would remain fairly static, as the Fossil project evolution shows. So far adopting of the Fossil Makefile project has been tried with the following IDEs: * [Eclipse CDT](#import-eclipse) (Linux) * [Visual Studio 2017](#import-vs) (Windows) The general approach for adopting the existing Fossil Makefile into an IDE is as follows: 1. Configure the Fossil project to generate the main Makefile (Linux and similar) ./configure --fossil-debug 1. Import the existing Makefile project into via IDE's wizard or other facility 1. Try to build the resulting project (to check the dependencies) 1. Adjust the IDE project settings to resolve missing dependencies 1. Test the code indexing whether definitions/implementations are resolved into correct sources 1. Create and test the Debug configuration (defined FOSSIL_DEBUG preprocessor macro) Below are the steps used to adopt Fossil Makefile project into the IDEs tested. <a name="import-eclipse"></a> __Eclipse CDT__ A configured Fossil Makefile-based project can be imported __as is__ into Eclipse CDT. With a few tweaks, it allows code-browsing, autocomplete, and debugging. 1. Configure the Fossil project to generate the main Makefile (Linux and similar) ./configure --fossil-debug 1. Do menu _File> Import> C/C++: Existing Code as Makefile Project_ 1. Browse to the Fossil project directory 1. Pick the configured Toolchain, e.g. `Linux GCC` 1. Once the import completed, the source tree is populated with source directories. At this point the project is already _buildable_, yet source browsing is not fully functional yet. Add the following settings: 1. Do Menu _Project> Properties> C/C++ General: Paths and Symbols_ 1. Add _Includes_ in workspace folders: `fossil/bld`, `fossil/src` 1. Add _Output Location_: `fossil/bld` 1. Do _Build_ and then menu _Project> C/C++ Index: Rebuild_ to pick up the generated sources needed for the code browsing and autocomplete 1. Navigate definitions/implementations. For example, in `src/main.c` function `version_cmd()` hover mouse over the call to `fossil_print()` -- this allows to peek at its implementation. Or select _Open Declaration_ from the context menu. 1. For running and debugging, create a new _Run:Run Configuration_ for _C/C++ Application_; name it `fossil`, pick a project executable `bin/fossil` and specify run arguments. For example: `version` 1.

For other information about use types, see: * [Administering User Capabilities](./) * [How Moderation Works](../forum.wiki#moderation) * [Users vs Subscribers](../alerts.md#uvs) * [Defense Against Spiders](../antibot.wiki) ## <a name="philosophy"></a>Philosophical Core The Setup user "owns" the Fossil repository and may delegate a subset of that power to one or more Admin users. The Setup user can grant Admin capability and take it away, but Admin users cannot grant themselves Setup capability, either directly via the Admin → Users UI page or via any indirect means. (If you discover indirect means to elevate Admin privilege to Setup, it's a bug, so please [report it][forum]!) It is common for the Setup user to have administrative control over the host system running the Fossil repository, whereas it makes no sense for Admin users to have that ability. If an Admin-only user had `root` access on a Linux box running the Fossil instance they are an Admin on, they could elevate their capability to Setup in several ways. (The `fossil user` command, the `fossil sql` command, editing the repository DB file directly, etc.) Therefore, if you wish to grant someone Setup-like capability on a Fossil repository but you're unwilling to give them a login on the host system, you probably want to grant them Admin capability instead. Admin power is delegated from Setup. When a Setup user grants Admin capability, it is an expression of trust in that user's judgement. Admin-only users must not fight against the policies of the Setup user. Such a rift would be just cause for the Setup user to strip the Admin user's capabilities. This may then create a fork in the project’s development effort as the ex-Admin takes their clone and stands it up elsewhere, so they may become that fork’s Setup user. A useful rule of thumb here is that Admin users should only change things that the Setup user has not changed from the stock configuration. In this way, an Admin-only user can avoid overriding the Setup user's choices. You can also look at the role of Admin from the other direction, up through the [user power hierarchy][ucap] rather than down from Setup. An Admin user is usually a “super-developer†role, given full control over the repository’s managed content: versioned artifacts in [the block chain][bc], [unversioned content][uv], forum posts, wiki articles, tickets, etc. We’ll explore these distinctions in the rest of this document. [bc]: ../blockchain.md [ucap]: ./index.md#ucap [uv]: ../unvers.wiki ## <a name="binary"></a>No Granularity Fossil doesn’t make any distinction between these two user types beyond this binary choice: Setup or Admin. A few features of Fossil are broken down so that only part of the feature is accessible to Admin, with the rest left only to Setup users, but for the most part each feature affected by this distinction is either Admin + Setup or Setup-only. We could add more capability letters to break down individual sub-features, but we’d run out of ASCII alphanumerics pretty quickly, and we might even run out of ASCII punctuation and symbols. Then would we need to shift to Unicode? Consider the Admin → Settings page, which is currently restricted to Setup users only: you might imagine breaking this up into several subsets so that some settings can be changed by Admin users. Is that a good idea? Maybe, but it should be done only after due consideration. It would definitely be wrong to assign a user capability bit to *each* setting on that page. Now consider the opposite sort of case, Admin → Skins. Fossil grants Admin users full access to this page so that the Admins can maintain and extend the skin as the repository evolves, not so Admins can switch the entire skin to another without consulting with the Setup user first. How would Fossil decide, using user capabilities only, which skin changes the Admin user is allowed to do, and which must be left to Setup? Do we assign a separate capability letter to each step in `/setup_skin`? Do we assign one more each to the five sections of a skin? (Header, Footer, CSS, JavaScript, and Details.) It quickly becomes unmanageable. ## <a name="capgroups"></a>Capability Groups We can break up the set of powers the Admin user capability grants into several groups, then defend each group as a coherent whole. ### <a name="security"></a>Security While establishing the Fossil repository's security policy is a task for the Setup user, *maintaining* that policy is something that Fossil allows a Setup user to delegate to trustworthy users via the Admin user capability: * **Manage users**: The only thing an Admin-only user cannot do on the Admin → Users page is grant Setup capability, either to themselves or to other users. The intent is that Admin users be able to take some of the load of routine user management tasks off the shoulders of the Setup user: delete accounts created by spammers, fix email alert subscriptions, reset passwords, etc. * **Security audit**: The Admin → Security-Audit page runs several tests on the Fossil repository's configuration, then reports potential problems it found and offers canned solutions. Those canned solutions do not do anything that an Admin-user could not do via other means, so this page offers the Admin-only user no more power than they otherwise had. For example, this page's "Take it Private" feature can also be done manually via Admin → Users. This page is a convenience, not a grant of new power to the Admin-only user. * **Logging**:<a id="log"></a> Admin-only users get to see the various Fossil logs in case they need to use them to understand a problem they're empowered to solve. An obvious example is a spam attack: the Admin might want to find the user's last-used IP, see if they cloned the repository, see if they attempted to brute-force an existing login before self-registering, etc. Some security-conscious people might be bothered by the fact that Admin-only users have these abilities. Think of a large IT organization: if the CIO hires a [tiger team][tt] to test the company's internal IT defenses, the line grunts fix the reported problems, not the CIO. ### <a name="administrivia"></a>Administrivia It is perfectly fine for a Fossil repository to only have Setup users, no Admin users. The smaller the repository, the more likely the repository has no Admin-only users. If the Setup user neither needs nor wants to grant Admin power to others, there is no requirement in Fossil to do so. [Setup capability is a pure superset of Admin capability.][sia] As the number of users on a Fossil repository grows, the value in delegating administrivia also grows, because the Setup user typically has other time sinks they consider more important. Admin users can take over the following routine tasks on behalf of the Setup user: * **Shunning**: After user management, this is one of the greatest powers of an Admin-only user. Fossil grants access to the Admin → Shunned page to Admin users rather than reserve it to Setup users because one of the primary purposes of [the Fossil shunning system][shun] is to clean up after a spammer, and that's exactly the sort of administrivia we wish to delegate to Admin users. Coupled with the Rebuild button on the same page, an Admin user has the power to delete the repository's entire [blockchain][bc]! This makes this feature a pretty good razor in deciding whether to grant someone Admin capability: do you trust that user to shun Fossil artifacts responsibly? Realize that shunning is cooperative in Fossil. As long as there are surviving repository clones, an Admin-only user who deletes the whole blockchain has merely caused a nuisance. An Admin-only user cannot permanently destroy the repository unless the Setup user has been so silly as to have no up-to-date clones. * **Moderation**: According to the power hierarchy laid out at the top of this article, Admins are greater than Moderators, so control over what Moderators can do clearly belongs to both Admins and to the Setup user(s). * **Status**: Although the Fossil `/stat` page is visible to every user with Read capability, there are several additional things this page gives access to when a user also has the Admin capability: * <p>[Email alerts][ale] and [backoffice](../backoffice.md) status. Admin-only users cannot modify the email alerts setup, but they can see some details about its configuration and current status.</p> * <p>The `/urllist` page, which is a read-only page showing the ways the repository can be accessed and how it has been accessed in the past. Logically, this is an extension to logging, [covered above](#log).</p> * <p>The Fossil repository SQL schema. This is not particularly sensitive information, since you get more or less the same information when you clone the repository. It's restricted to Admin because it's primarily useful in debugging SQL errors, which happen most often when Fossil itself is in flux and the schema isn't being automatically updated correctly. That puts this squarely into the "administrivia" category.</p> * <p>Web cache status, environment, and logging: more administrivia meant to help the Admin debug problems.</p> * **Configure search** [ale]: ../alerts.md [shun]: ../shunning.wiki ### <a name="cosmetics"></a>Cosmetics While the Setup user is responsible for setting up the initial "look" of a Fossil repository, the Setup user entrusts Admin users with *maintaining* that look. An Admin-only user therefore has the following special abilities: * Modify the repository skin * Create and modify URL aliases * Manage the "ad units" feature, if enabled. * Adjust the `/timeline` display preferences. * Change the "logo" element displayed by some skins. These capabilities allow an Admin-only user to affect the branding and possibly even the back-end finances of a project. This is why we began this document with a philosophical discussion: if you cannot entrust a user with these powers, you should not grant that user Admin capability. ## <a name="clones"></a>Clones and Backups Keep in mind that Fossil is a *distributed* version control system, which means that a user known to Fossil might have Setup capability on one repository but be a mere "user" on one of its clones. The most common case is that when you clone a repository, even anonymously, you gain Setup power over the local clone. The distinctions above therefore are intransitive: they apply only within a single repository instance. The exception to this is when the clone is done as a Setup user, since this also copies the `user` table on the initial clone. A user with Setup capability can subsequently say [`fossil conf pull all`][fcp] to update that table and everything else not normally synchronized between Fossil repositories. In this way, a Setup user can create multiple interchangeable clones. This is useful not only to guard against rogue Admin-only users, it is a useful element of a load balancing and failover system. ## <a name="apsu"></a>The All-Powerful Setup User Setup users get [every user capability](./ref.html) of Fossil except for [two exceptionally dangerous capabilities](#dcap), which they can later grant to themselves or to others. In addition, Setup users can use every feature of the Fossil UI. If Fossil can do a thing, a Setup user on that repo can make Fossil do it. Setup users can do many things that Admin users cannot: * Use all of the Admin UI features * See record IDs (RIDs) on screens that show them * See the MIME type of attachments on [`/ainfo` pages](/help?cmd=/ainfo) * See a remote repo’s HTTP [cache status](/help?cmd=/cachestat) and [pull cache entries](/help?cmd=/cacheget) * Edit a Setup user’s account! The “Admin†feature of Fossil UI is so-named because Admin users can use about half of its functions, but only Setup can use these pages: * **Access**: This page falls under the [Security](#security) category above, but like Configuration, it's generally something set up once and never touched, so only Setup users should change it. * **Configuration**: This page nominally falls under [Cosmetics](#cosmetics) above, but it's such a core part of the Fossil configuration — something every Setup user is expected to fully specify on initial repository setup — that we have trouble justifying any case where an Admin-only user would have good cause to modify any of it. This page is generally set up once and then never touched again. * **Email-Server**: This is an experimental SMTP server feature which is currently unused in Fossil. Should we get it working, it will likely remain Setup-only, since it will likely be used as a replacement for the platform’s default SMTP server, a powerful position for a piece of software to take. * **Login-Group**: [Login groups][lg] allow one Fossil repository to delegate user access to another. Since an Admin-only user on one repo might not have such access to another repo on the same host system, this must be a Setup-only task. * **Notification**: This is the main UI for setting up integration with a platform’s SMTP service, for use in sending out [email notifications][ale]. Because this screen can set commands to execute on the host, and because finishing the configuration requires a login on the Fossil host system, it is not appropriate to give Admin users access to it. * **Settings**: The [repository settings][rs] available via Admin → Settings have too wide a range of power to allow modification by Admin-only users: * <p><b>Harmless</b>: Admin-only users on a repository may well have checkin rights on the repository, so the fact that versionable settings like `crlf-glob` can also be set at the repository level seems like a thing we might want to allow Admin-only users the ability to change. Since Fossil currently has no way to allow only some settings to be changed by Admin-only users and some not, we can't just show these harmless settings to Admin-only users.</p> * <p><b>Low-Risk</b>: The <tt>admin-log</tt> setting controls whether the Fossil admin log is generated. Since we've <a href="#log">already decided</a> that Admin-only users can see this log, it seems fine that the Admin users can choose whether this log gets generated in the first place.</p> <p>There's a small risk that a rogue Admin user could disable the log before doing something evil that the log would capture, so ideally, we'd want to restrict changing this setting from 1 to 0 to Setup only while allowing Admin-only users to change it from 0 to 1. Fossil doesn't currently allow that.</p> * <p><b>Risky</b>: The <tt>https-login</tt> setting falls under the "Security" section above, but it should probably never be adjusted by Admin-only users. Sites that want it on will never want it to be disabled without a very good reason.</p> <p>There is also an inverse risk: if the site has a front-end HTTPS proxy that uses HTTP to communicate over localhost to Fossil, enabling this setting will create an infinite redirect loop! (Ask me how I know.)</p> * <p><b>Dangerous</b>: The <tt>email-send-command</tt> setting could allow a rogue Admin to run arbitrary commands on the host system, unless it's prevented via some kind of host-specific restriction. (chroot, jails, SELinux, VMs, etc.) Since it makes no sense to trust Admin-only users with <tt>root</tt> level access on the host system, we almost certainly don't want to allow them to change such settings.</p> * **SQL**: The Admin → SQL feature allows the Setup user to enter raw SQL queries against the Fossil repository via Fossil UI. This not only allows arbitrary ability to modify the repository blockchain and its backing data tables, it can probably also be used to damage the host such as via `PRAGMA temp_store = FILE`. * **Tickets**: This section allows input of aribtrary TH1 code that runs on the server, affecting the way the Fossil ticketing system works. The justification in the **TH1** section below therefore applies. * **TH1**: The [TH1 language][TH1] is quite restricted relative to the Tcl language it descends from, so this author does not believe there is a way to damage the Fossil repository or its host via the Admin → TH1 feature, which allows execution of arbitrary TH1 code within the repository's execution context. Nevertheless, interpreters are a well-known source of security problems, so it seems best to restrict this feature to Setup-only users as long as we lack a good reason for Admin-only users to have access to it. * **Transfers**: This is for setting up TH1 hooks on various actions, so the justification in the **TH1** section above applies. * **Wiki**: These are mainly cosmetic and usability settings. We might open this up to Admin users in the future. Just remember, [user caps affect Fossil’s web interfaces only][webo]. A user is a Setup user by default on their local clone of a repo, and Fossil’s ability to protect itself against malicious (or even simply incorrect) pushes is limited. Someone with clone and push capability on your repo could clone it, modify their local repo, and then push the changes back to your repo. Be careful who you give that combination of capabilities to! When you run [`fossil ui`][fui], you are the Setup user on that repo through that UI instance, regardless of the capability set defined in the repo’s user table. This is true even if you cloned a remote repo where you do not have Setup caps. This is why `ui` always binds to `localhost` without needing the `--localhost` flag: in this mode, anyone who can connect to that repo’s web UI has full power over that repo. ## <a name="dcap"></a>Dangerous Capabilities Initially Denied to Everyone There are two capabilities that Fossil doesn’t grant by default to Setup or Admin users automatically. They are exceptionally dangerous, so Fossil makes these users grant themselves (or others) these capabilities deliberately, hopefully after careful consideration. ### <a name="y"></a>Write Unversioned Fossil currently doesn’t distinguish the sub-operations of [`fossil uv`](/help?cmd=uv); they’re all covered by [**WrUnver**][capy] (“yâ€) capability. Since some of these operations are unconditionally destructive due to the nature of unversioned content, and since this goes against Fossil’s philosophy of immutable history, nobody gets cap “y†on a Fossil repo by default, not even the Setup or Admin users. A Setup or Admin user must grant cap “y†to someone — not necessarily themselves! — before modifications to remote unversioned content are possible. Operations on unversioned content made without this capability affect your local clone only. In this way, your local unversioned file table can have different content from that in its parent repo. This state of affairs will continue until your user either gets cap “y†and syncs that content with its parent or you say `fossil uv revert` to make your local unversioned content table match that of its parent repo. ### <a name="x"></a>Private Branch Push For private branches to remain private, they must never be accidentally pushed to a public repository. It can be [difficult to impossible][shun] to recover from such a mistake, so nobody gets [**Private**][capx] (“xâ€) capability on a Fossil repo by default, not even Admin or Setup users. There are two common uses for private branches. One use is part of a local social contract allowing individual developers to work on some things in private until they’re ready to push them up to the parent repository. This goes against [a core tenet][fdp] of Fossil’s design philosophy, but Fossil allows it, so some development organizations do this. If yours is one of these, you might give cap “x†to the “developer†category. The other use is in development organizations that follow the Fossil philosophy, where you do not work in private unless you absolutely must. You may have a public-facing project — let’s call it “SQLite†for the sake of argument — but then someone comes along and commissions a custom modification to your project which they wish to keep proprietary. You do your work on a private branch, which you absolutely must never push to the public repo, because that would be illegal. (Breach of contract, copyright violation on a work-for-hire agreement, etc.) If you are using Fossil in this way, we recommend that you give “x†capability to a special developer account only, if at all, to minimize the chance of an accidental push.

Once we used up most of the lowercase letters, we started using uppercase, and then during the development of the [forum feature][for] we assigned most of the decimal numerals. All of the lowercase ASCII letters are now assigned. Eventually, we might have to start using ASCII punctuation and symbols. We expect to run out of reasons to define new caps before we’re forced to switch to Unicode, though the possibilities for [mnemonic][mn] assignments with emoji are intriguing. <span style="vertical-align: bottom">😉</span> The existing caps are usually mnemonic, especially among the earliest and therefore most central assignments, made when we still had lots of letters to choose from. There is still hope for good future mnemonic assignments among the uppercase letters, which are mostly still unused. ## <a name="bitfield"></a>Why Not Bitfields? Some may question the use of ASCII character strings for [capability sets][ucap] instead of bitfields, which are more efficient, both in terms of storage and processing time. Fossil handles these character strings in one of two ways. For most HTTP hits, Fossil [expands][sexp] the string into a [`struct` full of flags][sff] so that later code can just do simple Boolean tests. In a minority of cases, where Fossil only needs to check for the presence of a single flag, it just does a [`strchr()` call][sc] on the string instead. Both methods are slower than bit testing in a bitfield, but keep the execution context in mind: at the front end of an HTTP request handler, where the nanosecond differences in such implementation details are completely swamped by the millisecond scale ping time of that repo’s network connection, followed by the required I/O to satisfy the request. Either method is plenty fast in that context. In exchange for this immeasurable cost per hit, we get human-readable capability sets. ## <a name="filter"></a>Why Doesn’t Fossil Filter “Bad†Artifacts on Sync? Fossil is more trusting about the content it receives from a remote clone during sync than you might expect. Common manifestations of this design choice are: 1. A user may be able to impersonate other users. This can be [accidental](./index.md#defuser) as well as purposeful. 2. If your local system clock is out-of-sync with absolute time, artifacts committed to that repo will appear with the “wrong†time when sync’d. If the time sync error is big enough, it can make check-ins appear to go back in time and other bad effects. 3. You can purposely overwrite good timestamps with bad ones and push those changes up to the remote with no interference, even though Fossil tries to make that a Setup-only operation. All of this falls out of two of Fossil’s design choices: sync is all-or-nothing, and [the Fossil block chain][bc] is immutable. Fossil would have to violate one or both of these principles to filter such problems out of incoming syncs. We have considered auto-[shunning][shun] “bad†content on sync, but this is [difficult][asd] due to [the design of the sync protocol][dsp]. This is not an impossible set of circumstances, but implementing a robust filter on this input path would be roughly as difficult as writing a basic [inter-frame video codec][ifvc]: do-able, but still a lot of work. Patches to do this will be thoughtfully considered. We can’t simply change content as it arrives. Such manipulations would change the artifact manifests, which would change the hashes, which would require rewriting all parts of the block chain from that point out to the tips of those branches. The local Fossil repo must then go through the same process as the remote one on subsequent syncs in order to build up a sync sequence that the remote can understand. Even if you’re willing to accept all of that, this would break all references to the old artifact IDs in forum posts, wiki articles, check-in comments, tickets, etc. The bottom line here is that [**Clone**](./ref.html#g) and [**Write**](./ref.html#i) are a potent combination of user capabilities. Be careful who you give that pair to! ----- *[Back to Administering User Capabilities](./)* <!-- add padding so anchor links always scroll ref’d section to top --> <div style="height: 75em"></div> [asd]: https://fossil-scm.org/forum/forumpost/ce4a3b5f3e [bc]: ../blockchain.md [dsp]: https://fossil-scm.org/fossil/doc/trunk/www/sync.wiki [for]: ./forum.wiki [ifvc]: https://en.wikipedia.org/wiki/Inter_frame [mn]: https://en.wikipedia.org/wiki/Mnemonic [ref]: ./ref.html [sexp]: http://fossil-scm.org/fossil/artifact?udc=1&ln=1223-1298&name=889d6724 [sff]: http://fossil-scm.org/fossil/artifact?udc=1&ln=80-117&name=52d2860f [sc]: https://en.cppreference.com/w/c/string/byte/strchr [shun]: ../shunning.wiki [ucap]: ./index.md#ucap |

We call this the capability system, or “caps†for short. Fossil stores a user’s caps as an unordered string of ASCII characters, one capability per, [currently](./impl.md#choices) limited to [alphanumerics][an]. Caps are case-sensitive: “**A**†and “**a**†are different user capabilities. This is a complex topic, so some sub-topics have their own documents: 1. [Login Groups][lg] 2. [Implementation Details](./impl.md) 3. [User Capability Reference](./ref.html) [an]: https://en.wikipedia.org/wiki/Alphanumeric [avs]: ./admin-v-setup.md [lg]: ./login-groups.md [rbac]: https://en.wikipedia.org/wiki/Role-based_access_control ## <a name="ucat"></a>User Categories Before we explain individual user capabilities and their proper administration, we want to talk about an oft-overlooked and misunderstood feature of Fossil: user categories. Fossil defines four user categories. Two of these apply based on the user’s login status: **nobody** and **anonymous**. The other two act like Unix or LDAP user groups: **reader** and **developer**. Because we use the word “group†for [another purpose][lg] in Fossil, we will avoid using it that way again in this document. The correct term in Fossil is “category.†Fossil user categories give you a way to define capability sets for four hard-coded situations within the Fossil C source code. Logically speaking: > *(developer* ∨ *reader)* ≥ *anonymous* ≥ *nobody* When a user visits a [served Fossil repository][svr] via its web UI, they initially get the capabilities of the “nobody†user category. This category would be better named “everybody†because it applies whether you’re logged in or not. When a user logs in as “anonymous†via [`/login`](/help?name=/login) they get all of the “nobody†category’s caps plus those assigned to the “anonymous†user category. It would be better named “user†because it affects all logged-in users, not just those logged in via Fossil’s anonymous user feature. When a user with either the “reader†([**u**][u]) or “developer†([**v**][v]) capability letter logs in, they get their [individual user caps](#ucap) plus those assigned to this special user category. They also get those assigned to the “anonymous†and “nobody†categories. Because “developer†users do not automatically inherit “reader†caps, it is standard practice to give both letters to your “developer†users: **uv**. You could instead just assign cap **u** to the “developer†category. Fossil shows how these capabilities apply hierarchically in the user editing screen (Admin → Users → name) with the `[N]` `[A]` `[D]` `[R]` tags next to each capability check box. If a user gets a capability from one of the user categories already assigned to it, there is no value in redundantly assigning that same cap to the user explicitly. For example, with the default **ei** cap set for the “developer†category, the cap set **ve** is redundant because **v** grants **ei**, which includes **e**. We suggest that you lean heavily on these fixed user categories when setting up new users. Ideally, your users will group neatly into one of the predefined categories, but if not, you might be able to shoehorn them into our fixed scheme. For example, the administrator of a wiki-only Fossil repo for non-developers could treat the “developer†user category as if it were called “author,†and a forum-only repo could treat the same category as if it were called “member.†There is currently no way to define custom user categories. [svr]: ../server/ ## <a name="ucap"></a>Individual User Capabilities When one or more users need to be different from the basic capabilities defined in user categories, you can assign caps to individual users. You may want to have the [cap reference][ref] open when doing such work. It is useful at this time to expand on the logical expression [above](#cat), which covered only the four fixed user categories. When we bring the individual user capabilities into it, the complete expression of the way Fossil implements user power becomes: > *setup* ≥ *admin* ≥ *moderator* ≥ *(developer* ∨ *reader)* ≥ *[subscriber]* ≥ *anonymous* ≥ *nobody* The two additions at the top are clear: [setup is all-powerful][apsu], and since admin users have [all capabilities][ref] except for Setup capability, they are [subordinate only to the setup user(s)][avsp]. The moderator insertion could go anywhere from where it’s shown now down to above the “anonymous†level, depending on what other caps you give to your moderators. Also, there is not just one type of moderator: Fossil has [wiki][l], [ticket][q], and [forum][5] moderators, each independent of the others. Usually your moderators are fairly high-status users, with developer capabilities or higher, but Fossil does allow the creation of low-status moderators. The placement of “subscriber†in that hierarchy is for the sort of subscriber who has registered an account on the repository purely to [receive email alerts and announcements][7]. Users with additional caps can also be subscribers, but not all users *are* in fact subscribers, which is why we show it in square brackets. (See [Users vs Subscribers](../alerts.md#uvs).) [apsu]: ./admin-v-setup.md#apsu [avsp]: ./admin-v-setup.md#philosophy ## <a name="new"></a>New Repository Defaults Fossil creates one user account in new repos, which is named after your OS user name [by default](#defuser). Fossil gives the initial repository user the [all-powerful Setup capability][apsu]. Users who visit a [served repository][svr] without logging in get the “nobody†user category’s caps which default to **[g][g][j][j][o][o][r][r][z][z]**: clone the repo, read the wiki, check-out files via the web UI, view tickets, and pull version archives. This default is suited to random passers-by on a typical FOSS project’s public web site and its code repository. Users who [prove they are not a bot][bot] by logging in — even if only as “anonymous†— get the “nobody†capability set plus **[h][h][m][m][n][n][c][c]**: see internal hyperlinks, append to existing wiki articles, file new tickets, and comment on existing tickets. We chose these additional capabilities as those we don’t want bots to have, but which a typical small FOSS project would be happy to give anonymous humans visiting the project site. The “reader†user category is typically assigned to users who want to be identified within the repository but who primarily have a passive role in the project. The default capability set on a Fossil repo adds **[k][k][p][p][t][t][w][w]** caps to those granted by “nobody†and “anonymousâ€. This category is not well-named, because the default caps are all about modifying repository content: edit existing wiki pages, change one’s own password, create new ticket report formats, and modify existing tickets. This category would be better named “participantâ€. Those in the “developer†category get the “nobody†and “anonymous†cap sets plus **[e][e][i][i]**: view sensitive user material and check in changes. [bot]: ../antibot.wiki ## <a name="pvt"></a>Consequences of Taking a Repository Private When you click Admin → Security-Audit → “Take it private,†one of the things it does is set the user capabilities for the “nobody†and “anonymous†user categories to blank, so that users who haven’t logged in can’t even see your project’s home page, and the option to log in as “anonymous†isn’t even offered. Until you log in with a user name, all you see is the repository’s skin and those few UI elements that work without any user capability checks at all, such as the “Login†link. Beware: Fossil does not reassign the capabilities these users had to other users or to the “reader†or “developer†user category! All users except those with Setup capability will lose all capabilities they inherited from “nobody†and “anonymous†categories. Setup is the [lone exception][apsu]. If you will have non-Setup users in your private repo, you should parcel out some subset of the capability set the “nobody†and “anonymous†categories had to other categories or to individual users first. ## <a name="read-v-clone"></a>Reading vs. Cloning Fossil has two capabilities that are often confused: [**Read**](./ref.html#o) and [**Clone**](./ref.html#g). The **Read** capability has nothing to do with reading data from a local repository, because [caps affect Fossil’s web interfaces only](#webonly). Once you’ve cloned a remote repository to your local machine, you can do any reading you want on that repository irrespective of whether your local user within that repo has <b>Read</b> capability. The repo clone is completely under your user’s power at that point, affected only by OS file permissions and such. If you need to prevent that, you want to deny **Clone** capability instead. Withholding the **Read** capability has a different effect: it prevents a web client from viewing [embedded documentation][edoc], using [the file browser](/help?name=/dir), and pulling file content via the [`/artifact`](/help?name=/artifact), [`/file`](/help?name=/file), and [`/raw`](/help?name=/raw) URLs. It is is common to withhold **Read** capability from low-status visitors on private or semi-private repos to prevent them from pulling individual elements of the repo over the web one at a time, as someone may do when denied the bulk **Clone** capability. [edoc]: ../embeddeddoc.wiki ## <a name="defuser"></a>Default User Name By default, Fossil assumes your OS user account name is the same as the one you use in any Fossil repository. It is the [default for a new repository](#new), though you can override this with [the `--admin-user` option][auo]. Fossil has other ways of overriding this in other contexts such as the `name@` syntax in clone URLs. It’s simplest to stick with the default; a mismatch can cause problems. For example, if you clone someone else’s repo anonymously, turn off autosync, and make check-ins to that repository, they will be assigned to your OS user name by default. If you later get a login on the remote repository under a different name and sync your repo with it, your earlier “private†check-ins will get synced to the remote under your OS user name! When such problems occur, you can amend the check-in to hide the incorrect name from Fossil reports, but the original values remain in the repository [forever][shun]. It is [difficult enough][fos] to fix such problems automatically during sync that we are unlikely to ever do so. [auo]: /help?name=new [fos]: ./impl.md#filter [shun]: ../shunning.wiki ## <a name="utclone"></a>Cloning the User Table When cloning over HTTP, the initial user table in the local clone is set to its “[new state:](#new)†only one user with Setup capability, named after either your OS user account, per the default above, or after the user given in the clone URL. There is one exception: if you clone as a named Setup user, you get a complete copy of the user information. This restriction keeps the user table private except for the only user allowed to make absolutely complete clones of a remote repo, such as for failover or backup purposes. Every other user’s clone is missing this and a few other items, either for information security or PII privacy reasons. When cloning with file system paths, `file://` URLs, or over SSH, you get a complete clone, including the parent repo’s complete user table. All of the above applies to [login groups][lg] as well. ## <a name="webonly"></a>Caps Affect Web Interfaces Only User caps only affect Fossil’s [UI pages][wp], remote operations over `http[s]://` URLs, and [the JSON API][japi]. User caps *do not* affect operations done on a local repo opened via a `file://` URL or a file system path. This should strike you as sensible: only local file permissions matter when operating on a local SQLite DB file. The same is true when working on a clone done over such a path, except that there are then two sets of file system permission checks: once to modify the working check-out’s repo clone DB file, then again on [sync][sync] with the parent DB file. The Fossil capability checks are effectively defeated because your user has [**Setup**][s] capability on both sides of the sync. What may surprise you is that user caps *also do not affect SSH!* When you make a change to such a repository, the change first goes to the local clone, where file system permissions are all that matter, but then upon sync, the situation is effectively the same as when the parent repo is on the local file system. If you can log into the remote system over SSH and that user has the necessary file system permissions on that remote repo DB file, it is the same situation as for `file://` URLs. All Fossil syncs are done over HTTP, even for `file://` and `ssh://` URLs: * For `ssh://` URLs, Fossil pipes the HTTP conversation through a local SSH client to a remote instance of Fossil running the [`test-http`](/help?name=test-http) command to recieve the tunneled HTTP connection without cap checks. The SSH client defaults to “`ssh -e none -T`†on most platforms, except on Windows where it defaults to “`plink -ssh -T`â€. You can override this with [the `ssh-command` setting](/help?name=ssh-command). * For `file://` URLs, the “sending†Fossil instance writes its side of the HTTP conversation out to a temporary file in the same directory as the local repo clone and then calls itself on the “receiving†repository to read that same HTTP transcript file back in to apply those changes to that repository. Presumably Fossil doesn’t do this with a pipe to ease portability to Windows. Because both mechanisms work on local repos, the checks for capabilities like [**Read**][o] and [**Write**][i] within the HTTP conversation for such URLs can never return “false,†because you are the [**Setup**][s] user on both sides of the conversation. Such checks only have a useful effect when done over an `http[s]://` URL. ## <a name="pubpg"></a>Public Pages In Admin → Access, there is an option for giving a list of [globs][glob] to name URLs which get treated as if the visitor had [the default cap set](#defcap). For example, you could take the [**Read**][o] capability away from the “nobody†user category, who has it by default, to prevent users without logins from pulling down your repository contents one artifact at a time, yet give those users the ability to read the project documentation by setting the glob to match your [embedded documentation][edoc]’s URL root. ## <a name="defcap"></a>Default User Capability Set In Admin → Access, you can define a default user capability set, which is used as: 1. the default caps for users newly created by an Admin or Setup user 2. the default caps for self-registered users, an option in that same UI 3. the effective caps for URIs considered [public pages](#pubpg) This defaults to [**Reader**][u]. <!-- add padding so anchor links always scroll ref’d section to top --> <div style="height: 75em"></div> [ref]: ./ref.html [a]: ./ref.html#a [b]: ./ref.html#b [c]: ./ref.html#c [d]: ./ref.html#d [e]: ./ref.html#e [f]: ./ref.html#f [g]: ./ref.html#g [h]: ./ref.html#h [i]: ./ref.html#i [j]: ./ref.html#j [k]: ./ref.html#k [l]: ./ref.html#l [m]: ./ref.html#m [n]: ./ref.html#n [o]: ./ref.html#o [p]: ./ref.html#p [q]: ./ref.html#q [r]: ./ref.html#r [s]: ./ref.html#s [t]: ./ref.html#t [u]: ./ref.html#u [v]: ./ref.html#v [w]: ./ref.html#w [x]: ./ref.html#x [y]: ./ref.html#y [z]: ./ref.html#z [2]: ./ref.html#2 [3]: ./ref.html#3 [4]: ./ref.html#4 [5]: ./ref.html#5 [6]: ./ref.html#6 [7]: ./ref.html#7 [glob]: https://en.wikipedia.org/wiki/Glob_(programming) [japi]: https://docs.google.com/document/d/1fXViveNhDbiXgCuE7QDXQOKeFzf2qNUkBEgiUvoqFN4/view#heading=h.6k0k5plm18p1 [sp]: ../sync.wiki [sync]: /help?name=sync [wp]: /help#webpages |

This feature ties changes to the “`user`†table in one repo to that in one or more other repos. With this configured, you get a new choice on the user edit screen, offering to make changes specific to the one repository only or to apply it to all others in the login group as well. A user can log into one repo in a login group only if that user has an entry in that repo’s user table. That is, setting up a login group doesn’t automatically transfer all user accounts from the joined repo to the joining repo. Only when a user exists by name in both repos will that user be able to share credentials across the repos. Login groups can have names, allowing one “master†repo to host multiple subsets of its users to other repos. Trust in login groups is transitive within a single server. If repo C joined repo B and repo B joined A, changes in C’s user table affect both A and B, if you tell Fossil that the change applies to all repos in the login group.

But a central server can help a project run more smoothly by giving developers a common point of rendezvous for syncing, and by providing a web-based portal where developers and non-developers alike can learn about the project and its current state. Setting up a server using Fossil is easy. A [./server/|separate document] talks about all of the many different methods for setting up a Fossil server, one of which is [./server/any/cgi.md | as a CGI script]. CGI is the technique that the three [./selfhost.wiki|self-hosting Fossil repositories] all use. Setting up a Fossil server using CGI is mostly about writing a short script (usually just 2 lines line) in the cgi-bin folder of an ordinary web-server. But there are a lot of extra options that can be added to this script, to customize the configuration. This article describes those options. <h1>CGI Script Options</h1> The CGI script used to launch a Fossil server will usually look something like this: <blockquote><verbatim> #!/usr/bin/fossil repository: /home/www/fossils/myproject.fossil </verbatim></blockquote> Of course, pathnames will likely be different. The first line (the "shebang") always gives the name of the Fossil executable. Subsequent lines are of the form "<b>property: argument ...</b>". The remainder of this document describes the available properties and their arguments. <hr> <h2 id="repository">repository: <i>PATH</i></h2> This property defines the Fossil repository that the server will use. Every Fossil CGI requires either this property or the [#directory|<b>directory:</b>] property (but not both). Many Fossil repository sets have this one property and no other. <h2 id="directory">directory: <i>PATH</i></h2> The PATH is the name of a directory that contains one or more Fossil repository files having the suffix ".fossil". If this property is used instead of [#repository|<b>repository:</b>], then the Fossil server is able to serve all of the repositories in the directory. The specific repository used is selected by a prefix on the PATH_INFO. <h2 id="errorlog">errorlog: <i>FILENAME</i></h2> This setting causes the server to log any errors in FILENAME. It is ok for multiple Fossil CGIs to share the same error log. Setting up an error log for Fossil servers is not required, but it is recommended. <h2 id="notfound">notfound: <i>URL</i></h2> If the [#directory|<b>directory:</b>] option is used and if the PATH_INFO of the HTTP request does not correspond to any Fossil repository, then the request redirects to URL. <h2 id="repolist">repolist</h2> This is a Boolean property. If it is present, and if the [#directory:|<b>directory:</b>] option is used, and if the PATH_INFO string is empty, then Fossil will show a list of available Fossil repositories. The "skin" of the reply is determined by the first repository in the list that has a non-zero [/help?cmd=repolist-skin|repolist-skin] setting. If no repository has such a non-zero repolist-skin setting, then the repository list is generic HTML without any decoration. <h2 id="extroot">extroot: <i>PATH</i></h2> This property defines the DOCUMENT_ROOT for the [./serverext.wiki|CGI Server Extensions]. If this property is present, then CGI Server Extensions are enabled. When this property is omitted, CGI Server Extensions are disabled. A cascade of CGI invocations can occur here. Fossil itself is started as CGI, then Fossil can turn around and invoke a sub-CGI extension. The sub-CGI extension outputs reply text, when Fossil then (optionally) augments with its own header and footer and returns to the original requestor. The property controls the DOCUMENT_ROOT of the sub-CGI. <h2 id="timeout">timeout: <i>N</i></h2> This property changes the timeout on each CGI request to N seconds. If N is zero, then there is no timeout. If this property is omitted, then the default timeout is 300 seconds (5 minutes). <h2 id="localauth">localauth</h2> This is a Boolean property. If it is present, [./caps/ref.html#s | setup capability] is granted to any HTTP request that comes in over a loopback interface, such as 127.0.0.1. If the PATH_INFO string is empty, Fossil will show a list of available Fossil repositories. <h2 id="skin">skin: <i>NAME</i></h2> If NAME is the name of one of the built-in skins supported by Fossil, then this option causes Fossil to display using that built-in skin, and to ignore any custom skin that might be configured in the repository itself. So, if you wanted to set up a server for a single Fossil project, but also give users the option to use several of the different built-in skins, you could create multiple CGI scripts, each with a different "<b>skin:</b>" property, but all pointing to the same <b>repository:</b>. Then users can select which skin to use by using the appropriate CGI. <h2 id="files">files: </i>GLOBLIST</i></h2> The GLOBLIST argument is a comma-separate list of "globs" that specify filenames. In [#directory|<b>directory:</b> mode], if the PATH_INFO does not identify any Fossil repository, but it does refer some other file in the directory, and that filename matches one of the glob patterns in the GLOBLIST, then the file is returned as static content. <h2 id="setenv">setenv: <i>NAME VALUE</i></h2> This parameter causes additional environment variable NAME to have VALUE. This parameter can be repeated as many times as necessary. <h2 id="HOME">HOME: <i>PATH</i></h2> This parameter is a short-hand for "<b>setenv HOME <i>PATH</i></b>". <h2 id="cgi-debug">cgi-debug: <i>FILE</i></h2> Cause CGI-related debugging information to be appended in <i>FILE</i>. Use this to help debug CGI problems. |

The same fix is also backported to version 2.10.1 and 2.11.1. New "safety-net" features were added to prevent similar problems in the future. * Enhancements to the graph display for cases when there are many cherry-pick merges into a single check-in. [/timeline?f=2d75e87b760c0a9|Example] * Enhance the [/help?cmd=open|fossil open] command with the new --workdir option and the ability to accept a URL as the repository name, causing the remote repository to be cloned automatically. * Enhance the markdown formatter to more closely follow the [https://spec.commonmark.org/0.29/#emphasis-and-strong-emphasis|CommonMark specification] with regard to text highlighting. Underscores in the middle of identifiers (ex: fossil_printf() no longer need to be escaped). * The markdown-to-html translator can prevent unsafe HTML (for example: <script>) on user-contributed pages like forum and tickets and wiki. The admin can adjust this behavior using the [/help?cmd=safe-html|safe-html setting] on the Admin/Wiki page. The default is to disallow unsafe HTML everywhere. [https://www.fossil-scm.org/forum/forumpost/3714e6568f|Example]. * Added the "collapse" and "expand" capability for long forum posts. [https://fossil-scm.org/forum/forumpost/9297029862|Example] * The "[/help?cmd=remote-url|fossil remote]" command now has options for specifying multiple persistent remotes with symbolic names. Currently only one remote can be used at a time, but that might change in the future. * Add the "Remember me?" checkbox on the login page. Use a session cookie for the login if it is not checked. * Added the experimental "[/help?cmd=hook|fossil hook]" command for managing "hook scripts" that run before checkin or after a push. * Enhance the [/help?cmd=revert|fossil revert] command so that it is able to revert all files beneath a directory. * Add the [/help?cmd=bisect|fossil bisect skip] command. * Enhance [/help?cmd=bisect|fossil bisect ui] so that it shows all unchecked check-ins in between the innermost "good" and "bad" check-ins. * Added the <tt>--reset</tt> flag to the "[/help?cmd=add|fossil add]", "[/help?cmd=rm|fossil rm]", and "[/help?cmd=addremove|fossil addremove]" commands. * Added the "<tt>--min</tt> <i>N</i>" and "<tt>--logfile</tt> <i>FILENAME</i>" flags to the [/help?cmd=backoffice|backoffice] command, as well as other enhancements to make the backoffice command a viable replacement for automatic backoffice. Other incremental backoffice improvements. * Added the [/help?cmd=/fileedit|/fileedit page], which allows editing of text files online. Requires explicit activation by a setup user. * Translate built-in help text into HTML for display on web pages. [/help?cmd=help|Example]. * On the [/help?cmd=/timeline|/timeline] webpage, the combination of query parameters "p=CHECKIN" and "bt=ANCESTOR" draws all ancestors of CHECKIN going back to ANCESTOR. For example, [/timeline?p=202006271506&bt=version-2.11] shows all ancestors of the checkin that occured on 2020-06-27 15:06 going back to the 2.11 release. * Update the built-in SQLite so that the "[/help?cmd=sql|fossil sql]" command supports new output modes ".mode box" and ".mode json". * Add the "<tt>obscure()</tt>" SQL function to the "[/help?cmd=sql|fossil sql]" command. * [./delta_format.wiki|Delta compression] is now applied to forum edits. * The [/help?cmd=/wikiedit|wiki editor] has been modernized and is now Ajax-based. The WYSIWYG editing option for Fossil-format wiki pages was removed. (Please let us know, via the site's Support menu, if that removal unduly impacts you.) This also changes the semantics of the wiki "Sandbox": that pseudo-page may be freely edited but no longer saved via the UI (the [/help?cmd=wiki|wiki CLI command] can, though). * Countless documentation enhancements. <a name='v2_11'></a> <h2>Changes for Version 2.11 (2020-05-25)</h2> * Support [/md_rules|Markdown] in the default ticket configuration. * Timestamp strings in [./checkin_names.wiki|object names] can now omit punctation. So, for example, "202004181942" and "2020-04-18 19:42" mean the same thing. * Enhance backlink processing so that it works with Markdown-formatted tickets and so that it works for wiki pages. Ticket [a3572c6a5b47cd5a]. <ul><li> "[/help?cmd=rebuild|fossil rebuild]" is needed to take full advantage of this fix. Fossil will continue to work without the rebuild, but the new backlinks will be missing.</ul> * The algorithm for finding the [./tech_overview.wiki#configloc|location of the configuration database] is enhanced to be XDG-compliant. * Add a hide/show feature to [./wikitheory.wiki#assocwiki|associated wiki] display on check-in and branch information pages. * Enhance the "[/help?cmd=info|fossil info]" command so that it works with no arguments even if not within an open check-out. * Many improvements to the forum and especially email notification of forum posts, in response to community feedback after switching SQLite support from a mailing list over to the forum. * Minimum length of a self-registered user ID increased from 3 to 6 characters. * When the "vfx" query parameter is used on the "[/help?cmd=/timeline|/timeline]" page, it causes the complete text of forum posts to be displayed. * Rework the "[/help?cmd=grep|fossil grep]" command to be more useful. * Expose the [/help?cmd=redirect-to-https|redirect-to-https] setting to the [/help?cmd=settings|settings] command. * Improve support for CGI on IIS web servers. * The [./serverext.wiki|/ext page] can now render index files, in the same way as the embedded docs. * Most commands now support the Unix-conventional "<tt>--</tt>" flag to treat all following arguments as filenames instead of flags. * Added the [/help?cmd=mimetypes|mimetypes config setting] (versionable) to enable mimetype overrides and custom definitions. * Add an option on the /Admin/Timeline setup page to set a default timeline style other than "Modern". * In [./embeddeddoc.wiki|embedded documentation], hyperlink URLs of the form "/doc/$CURRENT/..." the "$CURRENT" text is translated into the check-in hash for the document currently being viewed. * Added the [/help?cmd=/phantoms|/phantoms] webpage that shows all phantom artifacts. * Enhancements to phantom processing to try to reduce bandwidth-using chatter about phantoms on the sync protocol. * Security: Fossil now assumes that the schema of every database it opens has been tampered with by an adversary and takes extra precautions to ensure that such tampering is harmless. * Security: Fossil now puts the Content-Security-Policy in the HTTP reply header, in addition to also leaving it in the HTML <head> section, so that it is always available, even if a custom skin overrides the HTML <head> and omits the CSP in the process. * Output of the [/help?cmd=diff|fossil diff -y] command automatically adjusts according to the terminal width. * The Content-Security-Policy is now set using the [/help?cmd=default-csp|default-csp setting]. * Merge conflicts caused via the [/help?cmd=merge|merge] and [/help?cmd=update|update] commands no longer leave temporary files behind unless the new <tt>--keep-merge-files</tt> flag is used. * The [/help?cmd=/artifact_stats|/artifact_stats page] is now accessible to all users if the new "artifact_stats_enable" setting is turned on. There is a new checkbox under the /Admin/Access menu to turn that capability on and off. * Add the [/help?cmd=tls-config|fossil tls-config] command for viewing the TLS configuration and the list of SSL Cert exceptions. * Captchas all include a button to read the captcha using an audio file, so that they can be completed by the visually impaired. * Stop using the IP address as part of the login cookie. * Bug fix: fix the SSL cert validation logic so that if an exception is allowed for particular site, the exception expires as soon as the cert changes values. * Bug fix: the FTS search into for forum posts is now kept up-to-date correctly. * Bug fix: the "fossil git export" command is now working on Windows * Bug fix: display Technote items on the timeline correctly * Bug fix: fix the capability summary matrix of the Security Audit page so that it does not add "anonymous" capabilities to the "nobody" user. * Update internal Unicode character tables, used in regular expression handling, from version 12.1 to 13. * Many documentation enhancements. * Many minor enhancements to existing features. <a name='v2_10'></a> <h2>Changes for Version 2.10 (2019-10-04)</h2> * Added support for [./serverext.wiki|CGI-based Server Extensions]. * Added the [/help?cmd=repolist-skin|repolist-skin] setting used to add style to repository list pages. * Enhance the hierarchical display of Forum threads to do less indentation and to provide links back to the previous message in the thread. Provide sequential numbers for all messages in a forum thread. * Add support for fenced code blocks and improved hyperlink processing to the [/md_rules|markdown formatter]. * Add support for hyperlinks to wiki pages in the [/md_rules|markdown formatter]. * Enhance the [/help?cmd=/stat|/stat] page so that it gives the option to show a breakdown of forum posts. * The special check-in name "merge-in:BRANCH" means the source of the most recent merge-in from the parent branch of BRANCH. * Add hyperlinks to branch-diffs on the /info page and from timelines of a branch. * Add graphical context on the [/help?cmd=/vdiff|/vdiff] page. * Uppercase query parameters, POST parameters, and cookie names are converted to all lowercase and entered into the parameter set, instead of being discarded. * Change the default [./hashpolicy.wiki|hash policy] to SHA3. * Timeout [./server/any/cgi.md|CGI requests] after 300 seconds, or some other value set by the [./cgi.wiki#timeout|"timeout:" property] in the CGI script. * The check-in lock interval is reduced from 24 hours to 60 seconds, though the interval is now configurable using a setting. An additional check for conflicts is added after interactive check-in comment entry, to compensate for the reduced lock interval. * Performance optimizations. * Many documentation improvements. <a name='v2_9'></a> <h2>Changes for Version 2.9 (2019-07-13)</h2> * Added the [/help?cmd=git|fossil git export] command and instructions for [./mirrortogithub.md|creating a GitHub mirror of a Fossil project]. * Improved handling of relative hyperlinks on the [/help?cmd=/artifact|/artifact] pages for wiki. For example, hyperlinks and the lizard <img> now work correctly for both [/artifact/2ff24ab0887cf522] and [/doc/0d7ac90d575004c2415/www/index.wiki]. * Enhancements to the timeline graph layout, to show more information with less clutter. * Added tool-tips to the /timeline graph. On by default but can be disabled by setting the "Tooltip dwell time" to 0 in the timeline configuration. * Copy buttons added to various check-in hash and branch name links. * Double-clicking on a /timeline graph node now jumps to the /info page for the check-in. So, repurpose the timestamp hyperlink to show all activity around that check-in in time. * Added the [/help?cmd=touch|fossil touch] command, and the --setmtime option on the [/help?cmd=open|fossil open] and [/help?cmd=update|fossil update] commands. * Many documentation enhancements. * For the "[/help?cmd=update|fossil update]" and "[/help?cmd=checkout|fossil checkout]" commands, if a managed file is removed because it is no longer part of the target check-in and the directory containing the file is empty after the file is removed and the directory is not the current working directory and is not on the [/help?cmd=empty-dirs|empty-dirs] list, then also remove the directory. * Update internal Unicode character tables, used in regular expression handling, from version 11.0 to 12.1. * In "[/help?cmd=regexp|fossil regexp]", "[/help?cmd=grep|fossil grep]" and the TH1 "regexp" command, the -nocase option now removes multiple diacritics from the same character (derived from SQLite's remove_diacritics=2) * Added the [/help?cmd=/secureraw|/secureraw] page that requires the complete SHA1 or SHA3 hash, not just a prefix, before it will deliver content. * Accept purely numeric ISO8601 date/time strings as long as they do not conflict with a hash. Example: "20190510134217" instead of "2019-05-10 13:42:17". This helps keep URLs shorter and less complicated * Support both "1)" and "1." for numbered lists in markdown, as commonmark does. * The sync and clone HTTP requests omit the extra /xfer path element from the end of the request URI. All servers since 2010 know that the HTTP request is for a sync or clone from the mimetype so the extra path element is not needed. * If an automatic sync gets a permanent redirect request, then update the saved remote URL to the new address. * Temporary filenames (for example used for external "diff" commands) try to preserve the suffix of the original file. * Added the [/help?cmd=/thisdayinhistory|/thisdayinhistory] web page. * Enhanced parsing of [/help?cmd=/timeline|/timeline] query parameters "ymd=", "ym=", and "yw=". All arguments are option (in which case they default to the current time) and all accept ISO8601 date/times without punctuation. * Automatically disapprove pending moderation requests for a user when that user is deleted. This helps in dealing with spam-bots. * Improvements to the "Capability Summary" section in the [/help?cmd=/secaudit0|Security Audit] web-page. * Use new "ci-lock" and "ci-lock-failed" pragmas in the [./sync.wiki|sync protocol] to try to prevent accident forks caused by concurrent commits when operating in auto-sync mode. * Fix a bug ([https://www.fossil-scm.org/forum/forumpost/c51b9a1169|details]) that can cause repository databases to be overwritten with debugging output, thus corrupting the repository. This is only a factor when CGI debugging is enabled, and even then is a rare occurrence, but it is obviously an important fix. <a name='v2_8'></a> <h2>Changes for Version 2.8 (2019-02-20)</h2> * Show cherry-pick merges as dotted lines on the timeline graph. → The "fossil rebuild" command must be run to create and populate the new "cherrypick" table in the repository in order for this feature to operate. * Add the ability to associate branches, check-ins, and tags with specially-named Wiki pages. This gives the ability to better document branches and tags, and provide more documentation on check-ins beyond the check-in comment. The associated Wiki is automatically displayed on /info pages for check-ins, and on /timeline?r=BRANCH and /timeline?t=TAG pages for branches and tags. This feature is on by default, but can be disabled in on the Admin/Wiki page. * Enhance the repository list page (shown for example by "fossil all ui") so that it shows the name and last check-in time for each project. The implementation of the repository list page is now broken out into a separate source file (repolist.c). * Allow users with Forum Supervisor permission ('6') to add Forum Write Trusted permission ('4') to users as they are approving a forum post by that user. * When running a bisect, report the number of check-ins still in the search range and the estimated number of bisect steps remaining. Do this at each step of the bisect. * Provide a permanent link to a bisect timeline using the bid= query parameter. * Make the chronological forum display feature available to all users, and make it the default format on mobile devices. * Break out Wiki setup into a separate /setup_wiki page, accessible on the standard menus through Admin/Wiki. * Add "Next" and "Previous" buttons on the /wdiff page, allowing the user to step through the versions of a wiki page. * Improve the display of the /whistory page. * Omit the "HH:MM" timestamps on timeline graphs on narrow-screen devices, to improve horizontal space uses. This helps make Fossil more mobile-friendly. * Enhance /wcontent to show a sortable list of Wiki pages together with the number of revisions and the most recent change time for each page. * Hyperlinks to Wiki pages on the /timeline go to the specific version of the Wiki page named in the timeline, not to the latest version. * Enhancements to the "amend", "tag", and "reparent" commands, including adding options --override-date, --override-user, and --dry-run. * Add the global --comment-format command-line option and the comment-format setting to control the display of the command-line timeline. * Change the "fossil reparent" command so that it only works from within an active checkout. * On the /setup_ucap_list, show administrators how many users have each capability. The counts are a hyperlink to the /setup_ulist page showing the subset of users that have that capability. * Provide the ability to redirect all HTTP pages to HTTPS. Formerly one could cause this to occur for the /login page only. That option still exists, but the redirect can now also be done for all pages. * "Compress" the built-in javascript by omitting comments and leading and trailing whitespace. * Detect when the repository used by a checkout is swapped out for a clone that uses different RID values, and make appropriate adjustments to the checkout database to avoid any problems. * Add the backoffice-disable setting to completely disable the backoffice feature. * Update the built-in SQLite to version 3.27.1. * Various other small enhancements to webpages and documentation. <a name='v2_7'></a> <h2>Changes for Version 2.7 (2018-09-22)</h2> * Add the [./alerts.md|email alerts] feature for commits, ticket changes, wiki changes, forum posts, and announcements. This is still a work in progress. It is functional, but it is not as easy to setup and use as it ought to be. * Add the [./forum.wiki|discussion forum] feature. * Add new user capabilities letters needed to support alerts and forum. Formerly, user capabilities were letters from [a-z], but with the enhancements, the supply of lower case letters was exhausted. User capabilities are now letters in [a-zA-Z0-9]. * The built-in skins are now responsive, providing better layout on small screens, including mobile devices. * The default skin now includes a hamburger menu that is generated by the [/sitemap] page. * All of the built-in skins now use a [https://en.wikipedia.org/wiki/Content_Security_Policy|Content Security Policy (CSP)] to help prevent cross-site injection and forgery attacks. There are no known vulnerabilities in Fossil. The added CSP does not fix anything; it merely adds another layer of defense. * The [/sitemap] and other list pages show as multiple columns if the viewing window is wide enough. * There is an optional "js" file for each skin that can be used to hold javascript. This file can be loaded by reference or can be included in the header or footer. * Add the [./backoffice.md|backoffice]. * Update internal Unicode character tables, used in regular expression handling, from version 10.0 to 11.0. * Improvements to the "Security Audit" administration page * Add the [/help?cmd=branch|fossil branch current] command. * Add the [./grep.md|grep] command. * Update the built-in SQLite to version 3.25.1. * Some code and interfaces are in place to support sending and receiving email directly via SMTP, but this feature is not yet complete or ready for production use. * The `mv-rm-files` setting is now compiled into Fossil in the default Fossil configuration; no longer must you say <tt>./configure --with-legacy-mv-rm</tt> to make it available. The setting remains disabled by default, however, so you must still say <tt>fossil set mv-rm-files 1</tt> to enable it on each repository where you want hard <tt>mv/rm</tt> behavior. <a name='v2_6'></a> <h2>Changes for Version 2.6 (2018-05-04)</h2> * Fix a bug that was causing crashes while trying to clone the TCL repository. This fix is the main reason for the current release. * Added the new "Classic" timeline viewing mode. "Classic" is the same as "Verbose" in the previous release. The "Verbose" mode is now like "Compact" except the extra check-in details are shown by default. * Add support for ETags:, Last-Modified:, and If-Modified-Since: cache control mechanisms. * Enhance the [/help?cmd=/tarball|/tarball], [/help?cmd=/zip|/zip], and [/help?cmd=/sqlar|/sqlar] pages so that the checkin name to be downloaded can be expressed as part of the URI, and without the need for query parameters. * On the [/help?cmd=/timeline|/timeline] webpage, add the days=N query parameter and enhance the ymd=DATE and yw=DATE query parameters to accept 'now' as an argument to show the latest day or week. * In the web page that comes up in response to the [/help?cmd=all|fossil all ui] command, show the last modification time for each repository, and allow click-to-sort on the modification time column. * In the tarball cache replacement algorithm, give extra weight to tarballs that have been accessed more than once. * Additional defenses against web-based attacks. There have not been any known vulnerabilities. We are just being paranoid. * Update the built-in SQLite to an alpha version of 3.24.0. <a name='v2_5'></a> <h2>Changes for Version 2.5 (2018-02-07)</h2> * Numerous enhancements to the look and feel of the web interface. Especially: Added separate "Modern", "Compact", "Verbose", and "Columnar" view options on timelines. * Common display settings (such as the "view" option and the number of rows in a timeline) are held in a cookie and thus persist across multiple pages. * Rework the skin editing process so that changes are implemented on one of nine /draft pages, evaluated, then merged back to the default. * Added the [https://fossil-scm.org/skins/ardoise/timeline|Ardoise] skin. * Fix the "fossil server" command on Unix to be much more responsive to multiple simultaneous web requests. * Use the IPv6 stack for the "fossil ui" and "fossil server" commands on Windows. * Support for [https://sqlite.org/sqlar|SQL Archives] as a download option. * Fossil now automatically generates the <html><head>...</head><body> at the beginning of each web page if the configurable header lacks a <body> tag. * Added the /artifact_stats page, currently accessible only by the administrator. * Upgrade to the latest versions of SQLite and OpenSSL. * Improved key bindings on the Tk diff screen generated by "fossil diff --tk". * Begin factoring out in-line javascript into separately loaded script files. This is a step along the road toward supporting a strict Content Security Policy. More work is to be done. * Initial infrastructure is in place to make use of the pledge() system call in OpenBSD. More work is to be done. <a name='v2_4'></a> <h2>Changes for Version 2.4 (2017-11-03)</h2> * New feature: URL Aliases. URL Aliases allow an administrator to define their own URLs on the web interface that are rewritten to built-in URLs with specific parameters. Create and configure URL Aliases using the /Setup/URL_Aliases menu option in the web interface. * Add tech-note search capability. * Add the -r|--revision and -o|--origin options to the [/help?cmd=annotate|annotate] command. * Add the origin= query parameter to the [/help?cmd=/annotate|/annotate] webpage. * The [/help?cmd=annotate|fossil annotate] command and the [/help?cmd=/annotate|/annotate] web page go backwards in time as far as can be computed in 30 milliseconds by default, rather than stopping after 20 steps. The new limit= query parameter or the --limit command-line option can be used to alter this timeout. * Provide separate [/help#settings|on-line help screens for each setting]. * Back out support for the --no-dir-symlinks option * Remove support from the legacy configuration sync protocol. The only way now to do a configuration push or pull is to use the new protocol that was added in 2011. * Add the from= and to= query parameters to [/help?cmd=/fdiff|/fdiff] in order to get a diff of two files in the same check-in. * Fix the "ssh://" protocol to prevent an attack whereby the attacker convinces a victim to run a "clone" with a dodgy URL and thereby gains access to their system. * Provide a checkbox that will temporarily disable all ad-units. * Improvements to the [/help?cmd=/stat|/stat] page * Various new hyperlinks to the [/help?cmd=/bloblist|/bloblist] and [/help?cmd=/bigbloblist|/bigbloblist] pages. * Correct the [/help?cmd=/doc|/doc] page to support read-only repositories. * Correct [/help?cmd=/zip|/zip], [/help?cmd=/tarball|/tarball], [/help?cmd=zip|zip], and [/help?cmd=tarball|tarball] pages and commands to honor the versioned manifest setting when outside of an open checkout directory. * The admin-log and access-log settings are now on by default for new repositories. * Update the built-in SQLite to version 3.21.0. <a name='v2_3'></a> <h2>Changes for Version 2.3 (2017-07-21)</h2> * Update the built-in SQLite to version 3.20.0 (beta). * Update internal Unicode character tables, used in regular expression handling, from version 9.0 to 10.0. * Show the last-sync-URL on the [/help?cmd=/urllist|/urllist] page. * Added the "Event Summary" activity report. [/reports?type=ci&view=lastchng|example] * Added the "Security Audit" page, available to administrators only * Added the Last Login time to the user list page, for administrators only * Added the --numstat option to the [/help?cmd=diff|fossil diff] command * Limit the size of the heap and stack on unix systems, as a proactive defense against the [https://www.qualys.com/2017/06/19/stack-clash/stack-clash.txt|Stack Clash] attack. * Fix "database locked" warnings caused by "PRAGMA optimize". * Fix a potential XSS vulnerability on the [/help?cmd=/help|/help] webpage. * Documentation updates <a name='v2_2'></a> <h2>Changes for Version 2.2 (2017-04-11)</h2> * GIT comment tags are now handled by Fossil during import/export. * Show the content of README files on directory listings. ([/file/skins|example]) * Support for Basic Authentication if enabled (default off). * Show the hash algorithms used on the [/help?cmd=/rcvfromlist|/rcvfromlist] page. * The [/help?cmd=/tarball|/tarball] and [/help?cmd=/zip|/zip] pages now use the the r= query parameter to select which check-in to deliver. The uuid= query parameter is still accepted for backwards compatibility. * Update the built-in SQLite to version 3.18.0. * Run "[https://www.sqlite.org/pragma.html#pragma_optimize|PRAGMA optimize]" on the database connection as it is closing. <a name='v2_1'></a> <h2>Changes for Version 2.1 (2017-03-10)</h2> * Add support for [./hashpolicy.wiki|hash policies] that control which of the Hardened-SHA1 or SHA3-256 algorithms is used to name new artifacts. * Add the "gshow" and "gcat" subcommands to [/help?cmd=stash|fossil stash]. * Add the [/help?cmd=/juvlist|/juvlist] web page and use it to construct the [/uv/download.html|Download Page] of the Fossil self-hosting website using Ajax. <a name='v2_0'></a> <h2>Changes for Version 2.0 (2017-03-03)</h2> * Use the [https://github.com/cr-marcstevens/sha1collisiondetection|hardened SHA1] implemenation by Marc Stevens and Dan Shumow. * Add the ability to read and understand [./fileformat.wiki#names|artifact names] that are based on SHA3-256 rather than SHA1, but do not actually generate any such names. * Added the [/help?cmd=sha3sum|sha3sum] command. * Update the built-in SQLite to version 3.17.0. <a name='v1_37'></a> <h2>Changes for Version 1.37 (2017-01-16)</h2> * Add checkbox widgets to various web pages. See [/technote/8d18bf27e9| this technote] for more information. To get the checkboxes to look as intended, you must update the CSS in your repository and all clones. * Add the [/help/all|fossil all ui] command * Add the [/help?cmd=/file|/file] webpage * Enhance the [/help?cmd=/brlist|/brlist] webpage to make use of branch colors. * Add support for the ms=EXACT|LIKE|GLOB|REGEXP query parameter on the [/help?cmd=/timeline|/timeline] webpage, with associated form widgets. * Enhance the [/help/changes|changes] and [/help/status|status] commands with many new filter options so that specific kinds of changes can be found without having to pipe through grep or sed. * Enhanced the [/help/sqlite3|fossil sql] command so that it opens the [./tech_overview.wiki#localdb|checkout database] and the [./tech_overview.wiki#configdb|configuration database] in addition to the respository database. * TH1 enhancements: <ul><li>Add <nowiki>[unversioned content]</nowiki> command.</li> <li>Add <nowiki>[unversioned list]</nowiki> command.</li> <li>Add project_description variable.</li> </ul> * Rename crnl-glob [/help/settings|setting] to crlf-glob, but keep crnl-glob as a compatibility alias. * Added the --command option to the [/help/diff|diff] command. * Fix a C99-ism that prevents the 1.36 release from building with MSVC. * Fix [/help?cmd=ticket|ticket set] when using the "+" prefix with fields from the "ticketchng" table. * Remove the "fusefs" command from builds that do not have the underlying support enabled. * Fixes for incremental git import/export. * Minor security enhancements to [./encryptedrepos.wiki|encrypted repositories]. * Update the built-in SQLite to version 3.16.2. * Update the built-in Zlib to version 1.2.11. <a name='v1_36'></a> <h2>Changes for Version 1.36 (2016-10-24)</h2> * Add support for [./unvers.wiki|unversioned content], the [/help?cmd=unversioned|fossil unversioned] command and the [/help?cmd=/uv|/uv] and [/uvlist] web pages. * The [/uv/download.html|download page] is moved into [./unvers.wiki|unversioned content] so that the self-hosting Fossil websites no longer uses any external content. * Added the "Search" button to the graphical diff generated by the --tk option on the [/help?cmd=diff|diff] command. * Added the "--checkin VERSION" option to the [/help?cmd=diff|diff] command. * Various performance enhancements to the [/help?cmd=diff|diff] command. * Update internal Unicode character tables, used in regular expression handling, from version 8.0 to 9.0. * Update the built-in SQLite to version 3.15. Fossil now requires the SQLITE_DBCONFIG_MAINDBNAME interface of SQLite which is only available in SQLite version 3.15 and later and so Fossil will not work with earlier SQLite versions. * Fix [https://www.mail-archive.com/fossil-users@lists.fossil-scm.org/msg23618.html|multi-line timeline bug] * Enhance the [/help?cmd=purge|fossil purge] command. * New command [/help?cmd=shell|fossil shell]. * SQL parameters whose names are all lower-case in Ticket Report SQL queries are filled in using HTTP query parameter values. * Added support for [./childprojects.wiki|child projects] that are able to pull from their parent but not push. * Added the -nocomplain option to the TH1 "query" command. * Added support for the chng=GLOBLIST query parameter on the [/help?cmd=/timeline|/timeline] webpage. <a name='v1_35'></a> <h2>Changes for Version 1.35 (2016-06-14)</h2> * Enable symlinks by default on all non-Windows platforms. * Enhance the [/md_rules|Markdown formatting] so that hyperlinks that begin with "/" are relative to the root of the Fossil repository. * Rework the [/help?cmd=/setup_ulist|/setup_list page] (the User List page) to display all users in a click-to-sort table. * Fix backslash-octal escape on filenames while importing from git * When markdown documents begin with <h1> HTML elements, use that header at the document title. * Added the [/help?cmd=/bigbloblist|/bigbloblist page]. * Enhance the [/help?cmd=/finfo|/finfo page] so that when it is showing the ancestors of a particular file version, it only shows direct ancestors and omits changes on branches, thus making it show the same set of ancestors that are used for [/help?cmd=/blame|/blame]. * Added the --page option to the [/help?cmd=ui|fossil ui] command * Added the [/help?cmd=bisect|fossil bisect ui] command * Enhanced the [/help?cmd=diff|fossil diff] command so that it accepts directory names as arguments and computes diffs on all files contained within those directories. * Fix the [/help?cmd=add|fossil add] command so that it shows "SKIP" for files added that were already under management. * TH1 enhancements: <ul><li>Add <nowiki>[array exists]</nowiki> command.</li> <li>Add minimal <nowiki>[array names]</nowiki> command.</li> <li>Add tcl_platform(engine) and tcl_platform(platform) array elements.</li> </ul> * Get autosetup working with MinGW. * Fix autosetup detection of zlib in the source tree. * Added autosetup detection of OpenSSL when it may be present under the "compat" subdirectory of the source tree. * Added the [/help?cmd=reparent|fossil reparent] command * Added --include and --exclude options to [/help?cmd=tarball|fossil tarball] and [/help?cmd=zip|fossil zip] and the in= and ex= query parameters to the [/help?cmd=/tarball|/tarball] and [/help?cmd=/zip|/zip] web pages. * Add support for [./encryptedrepos.wiki|encrypted Fossil repositories]. * If the FOSSIL_PWREADER environment variable is set, then use the program it names in place of getpass() to read passwords and passphrases * Option --baseurl now works on Windows. * Numerious documentation improvements. * Update the built-in SQLite to version 3.13.0. <a name='v1_34'></a> <h2>Changes for Version 1.34 (2015-11-02)</h2> * Make the [/help?cmd=clean|fossil clean] command undoable for files less than 10MiB. * Update internal Unicode character tables, used in regular expression handling, from version 7.0 to 8.0. * Add the new [/help?cmd=amend|amend] command which is used to modify tags of a "check-in". * Fix bug in [/help?cmd=import|import] command, handling version 3 of the svndump format for subversion. * Add the [/help?cmd=all|all cache] command. * TH1 enhancements: <ul><li>Add minimal <nowiki>[lsearch]</nowiki> command.

Added the -x alias for --verily. * Add the --soft and --hard options to [/help?cmd=rm|fossil rm] and [/help?cmd=mv|fossil mv]. The default is still --soft, but that is now configurable at compile-time or by the mv-rm-files setting. * Improved ability to [./customgraph.md|customize the timeline graph]. * Improvements to the [/sitemap] page. * Automatically adjust the [/help?cmd=timeline|CLI timeline] to the terminal width on Linux. * Added <nowiki>[info commands] and [info vars]</nowiki> commands to TH1. These commands perform the same function as their Tcl counterparts, except they do not accept a pattern argument. * Fix some obscure issues with TH1 expression processing. * Fix titles in search results for documents that are not wiki, markdown, or HTML. * Formally translate TH1 to Tcl return codes and vice-versa, where necessary, in the Tcl integration subsystem. * Add [/help?cmd=leaves|fossil leaves -multiple], for finding multiple leaves on the same branch. * Added the "Blitz" skin option. * Removed the ".fossil-settings/keep-glob" file. It should not have been checked into the repository. * Update the built-in SQLite to version 3.8.10.2. * Make [/help?cmd=open|fossil open] honor ".fossil-settings/allow-symlinks". * Allow [/help?cmd=add|fossil add] to be used on symlinks to nonexistent or unreadable files in the same way as [/help?cmd=addremove|fossil addremove]. * Added fork warning to be issued if sync produced a fork * Update the [/help?cmd=/info|info] page to report when a file becomes a symlink. Additionally show the UUID for files whose types have changed without changing contents or symlink target. * Have [/help?cmd=changes|fossil changes] and [/help?cmd=status|fossil status] report when executable or symlink status changes on otherwise unmodified files. * Permit filtering weekday and file [/help?cmd=/reports|reports] by user. Also ensure the user parameter is preserved when changing types. Add a field for direct entry of the user name to each applicable report. * Create parent directories of [/help?cmd=settings|empty-dirs] if they don't already exist. * Inhibit timeline links to wiki pages that have been deleted. <a name='v1_33'></a> <h2>Changes for Version 1.32 (2015-03-14)</h2> * When creating a new repository using [/help?cmd=init|fossil init], ensure that the new repository is fully compatible with historical versions of Fossil by having a valid manifest as RID 1. * Anti-aliased rendering of arrowheads on timeline graphs. * Added vi/less-style key bindings to the --tk diff GUI. * Documentation updates to fix spellings and changes all "checkins" to "check-ins". * Add the --repolist option to server commands such as [/help?cmd=server|fossil server] or [/help?cmd=http|fossil http]. * Added the "Xekri" skin. * Enhance the "ln=" query parameter on artifact displays to accept multiple ranges, separate by spaces (or "+" when URL-encoded). * Added [/help?cmd=forget|fossil forget] as an alias for [/help?cmd=rm|fossil rm]. <a name='v1_31'></a> <h2>Changes For Version 1.31 (2015-02-23)</h2> * Change the auxiliary schema by adding columns MLINK.ISAUX and MLINK.PMID columns to the schema, to support better drawing of file change graphs. A [/help?cmd=rebuild|fossil rebuild] is recommended but is not required. so that the new graph drawing logic can work effectively. * Added [/search|search] over Check-in comments, Documents, Tickets and Wiki. Disabled by default. The search can be either a full-scan or it can use an index that is kept up-to-date automatically. The new /srchsetup web-page and the [/help?cmd=fts-config|fts-config] command were added to help configure the search capability. Expect further enhancements to the search capabilities in subsequent releases. * Added form elements to some submenus (in particular the /timeline) for easier operation. * Added the --ifneeded option to [/help?cmd=rebuild|fossil rebuild]. * Added "override skins" using the "skin:" line of the CGI script or using the --skin LABEL option on the [/help?cmd=server|server], [/help?cmd=ui|ui], or [/help?cmd=http|http] commands. * Embedded html documents that begin with <doc class="fossil-doc"> are displayed with standard headers and footers added. * Allow <div style='...'> markup in [/wiki_rules|wiki]. * Renamed "Events" to "Technical Notes", while updating the technote display and control pages.

Some hyperlinks to pages that require "anonymous" privileges are displayed even if the current user is "nobody" but automatically redirect to /login. * The [/help?cmd=/doc|/doc] web-page will now try to deliver the file "404.md" from the top-level directory (if such a file exists) in place of its built-in 404 text. * Download of Tarballs and ZIP Archives by user "nobody" is now enabled by default in new repositories. * Enhancements to the table sorting controls. More display tables are now sortable. * Add IPv6 support to [/help?cmd=sync|fossil sync] and [/help?cmd=clone|fossil clone] * Add more skins such as "San Francisco Modern" and "Eagle". * During shutdown, check to see if the check-out database (".fslckout") contains a lot of free space, and if it does, VACUUM it. * Added the [/mimetype_list] page. * Added the [/hash-collisions] page. * Allow the user of Common Table Expressions in the SQL that defaults ticket reports. * Break out the components (css, footer, and header) for the various built-in skins into separate files in the source tree. <a name='v1_30'></a> <h2>Changes For Version 1.30 (2015-01-19)</h2> * Added the [/help?cmd=bundle|fossil bundle] command. * Added the [/help?cmd=purge|fossil purge] command. * Added the [/help?cmd=publish|fossil publish] command. * Added the [/help?cmd=unpublished|fossil unpublished] command. * Enhance the [/tree] webpage to show the age of each file with the option to sort by age. * Enhance the [/brlist] webpage to show additional information about each branch and to be sortable by clicking on column headers. * Add support for Docker. Just install docker and type "sudo docker run -d -p 8080:8080 nijtmans/fossil" to get it running. * Add the [/help/fusefs|fossil fusefs DIRECTORY] command that mounts a Fuse Filesystem at the given DIRECTORY and populates it with read-only copies of all historical check-ins. This only works on systems that support FuseFS. * Add the administrative log that records all configuration. * Added the [/sitemap] webpage. * Added the [/bloblist] web page. * Let [/help?cmd=new|fossil new] no longer create an initial empty commit by default. The first commit after checking out an empty repository will become the initial commit. * Added the [/help?cmd=all|fossil all dbstat] and [/help?cmd=all|fossil all info] commands. * Update SQLite to version 3.8.8. * Added the --verily option to the [/help?cmd=clean|fossil clean] command. * Add the "autosync-tries" setting to control the number of autosync attempts before returning an error. * Added a compile-time option (--with-miniz) to build using miniz instead of zlib. Disabled by default. * Support customization of commands and webpages, including the ability to add new ones, via the "TH1 hooks" feature. Disabled by default. Enabled via a compile-time option. * Add the <nowiki>[checkout], [render], [styleHeader], [styleFooter], [trace], [getParameter], [setParameter], [artifact], and [globalState]</nowiki> commands to TH1, primarily for use by TH1 hooks. * Automatically adjust the width of command-line timeline output according to the detected width of the terminal. * Prompt the user to optionally fix invalid UTF-8 at check-in. * Added a line-number toggle option to the [/help?cmd=/info|/info] and [/help?cmd=/artifact|/artifact] pages. * Most commands now issue errors rather than silently ignoring unrecognized command-line options. * Use full 40-character SHA1 hashes (instead of abbreviations) in most internal URLs. * The "ssh:" sync method on Windows now uses "plink.exe" instead of "ssh" as the secure-shell client program. * Prevent a partial clone when the connection is lost. * Make the distinction between 301 and 302 redirects. * Allow commits against a closed check-in as long as the commit goes onto a different branch. * Improved cache control in the web interface reduces unnecessary requests for common resources like the page logo and CSS. * Fix a rare and long-standing sync protocol bug that would silently prevent the sync from running to completion. Before this bug-fix it was sometimes necessary to do "fossil sync --verily" to get two repositories in sync. * Add the [/finfo?name=src/foci.c|files_of_checkin] virtual table - useful for ad hoc queries in the [/help?cmd=sqlite3|fossil sql] interface, and also used internally. * Added the "$secureurl" TH1 variable for use in headers and footers. * (Internal:) Add the ability to include resources as separate files in the source tree that are converted into constant byte arrays in the compiled binary. Use this feature to store the Tk script that implements the --tk diff option in a separate file for easier editing. * (Internal:) Implement a system of compile-time checks to help ensure the correctness of printf-style formatting strings. * Fix CVE-2014-3566, also known as the POODLE SSL 3.0 vulnerability. * Numerous documentation fixes and improvements. * Other obscure and minor bug fixes - see the timeline for details. <a name='v1_29'></a> <h2>Changes For Version 1.29 (2014-06-12)</h2> * Add the ability to display content, diffs and annotations for UTF16 text files in the web interface. * Add the "SaveAs..." and "Invert" buttons to the graphical diff display that results from using the --tk option with the [/help/diff | fossil diff] command. * The [/reports] page now requires Read ("o") permissions. The "byweek" report now properly propagates the selected year through the event type filter links. * The [/help/info | info command] now shows leaf status of the checkout. * Add support for tunneling https through a http proxy (Ticket [e854101c4f]). * Add option --empty to the "[/help?cmd=open | fossil open]" command. * Enhanced [/help?cmd=/fileage|the fileage page] to support a glob parameter. * Add -w|--ignore-all-space and -Z|--ignore-trailing-space options to [/help?cmd=annotate|fossil annotate], [/help?cmd=blame|fossil blame], [/help?cmd=diff|fossil (g)diff], [/help?cmd=stash|fossil stash diff]. * Add --strip-trailing-cr option to [/help?cmd=diff|fossil (g)diff] and [/help?cmd=stash|fossil stash diff]. * Add button "Ignore Whitespace" to /annotate, /blame, /ci, /fdiff and /vdiff UI pages. * Enhance [/reports?view=byweekday|/reports] with a "byweekday" view. * Enhance the [/help?cmd=cat|fossil cat] command so that it works outside of a checkout when using the -R command-line option. * Use full-length SHA1 hashes, not abbreviations, in most hyperlinks. * Correctly render the <title> markup on wiki pages in the [/help?cmd=/artifact|/artifact] webpage. * Enhance the [/help?cmd=whatis|fossil whatis] command to report on attachments and cluster artifacts. Added the [/help?cmd=test-whatis-all] command for testing purposes. * Add support for HTTP Basic Authentication on [/help?cmd=clone|clone] and [/help?cmd=sync|sync]. * Fix the [/help?cmd=stash|stash] so that it remembers added files and re-adds them when the stash is applied. * Fix the server so that it avoids writing to the database (and thus avoids database locking issues) on a [/help?cmd=pull|pull] or [/help?cmd=clone|clone]. * Add support for [./server.wiki#loadmgmt|server load management] using both a cache of expensive pages (the [/help?cmd=cache|fossil cache] command) and by rejecting expensive page requests when the server load average is too high. * Add the [/help?cmd=praise|fossil praise] command as an alias for [/help?cmd=blame|fossil blame] for subversion compatibility. * Enhance the [/help?cmd=test-diff|fossil test-diff] command with -y or --tk options so that it shows both filenames above their respective columns in the side-by-side diff output. * Issue a warning if a [/help?cmd=add|fossil add] command tries to add a file that matches the ignore-glob. * Add option -W|--width to "[/help?cmd=stash|fossil stash ls]" and "[/help?cmd=leaves|fossil leaves]" commands. * Enhance support for running as the root user. Now works on Haiku. * Added the <tt>-empty</tt> option to [/help?cmd=new|fossil new], which causes it to not create an initial empty commit. The first commit after checking out a repo created this way will become the initial commit. * Enhance sync operations by committing each round-trip to minimize number of retransmits when autosync fails. Include option for [/help?cmd=update| fossil update] and [/help?cmd=merge| fossil merge] to continue even if missing content. * Minor portability fixes for platforms where the char type is unsigned by default. <h2>Changes For Version 1.28 (2014-01-27)</h2> * Enhance [/help?cmd=/reports | /reports] to support event type filtering. * When cloning a repository, the user name passed via the URL (if any) is now used as the default local admin user's name. * Enhance the SSH transport mechanism so that it runs a single instance of the "fossil" executable on the remote side, obviating the need for a shell on the remote side. Some users may need to add the "?fossil=/path/to/fossil" query parameter to "ssh:" URIs if their fossil binary is not in a standard place. * Add the "[/help?cmd=blame | fossil blame]" command that works just like "fossil annotate" but uses a different output format that includes the user who made each changes and omits line numbers. * Add the "Tarball and ZIP-archive Prefix" configuration parameter under Admin/Configuration. * Fix CGI processing so that it works on web servers that do not supply REQUEST_URI. * Add options --dirsonly, --emptydirs, and --allckouts to the "[/help?cmd=clean | fossil clean]" command. * Ten-fold performance improvement in large "fossil blame" or "fossil annotate" commands. * Add option -W|--width and --offset to "[/help?cmd=timeline | fossil timeline]" and "[/help?cmd=finfo | fossil finfo]" commands. * Option -n|--limit of "[/help?cmd=timeline | fossil timeline]" now specifies the number of entries, just like all other commands which have the -n|--limit option. The various timeline-related functions now output "--- ?? limit (??) reached ---" at the end whenever appropriate. Use "-n 0" if no limit is desired. * Fix handling of password embedded in Fossil URL. * New <tt>--once</tt> option to [/help?cmd=clone | fossil clone] command which does not store the URL or password when cloning. * Modify [/help?cmd=ui | fossil ui] to respect "default user" in an open repository. * Fossil now hides check-ins that have the "hidden" tag in timeline webpages. * Enhance <tt>/ci_edit</tt> page to add the "hidden" tag to check-ins. * Advanced possibilities for commit and ticket change notifications over http using TH1 scripting. * Add --sha1sum and --integrate options to the "[/help?cmd=commit | fossil commit]" command. * Add the "clean" and "extra" subcommands to the "[/help?cmd=all | fossil all]" command * Add the --whatif option to "[/help?cmd=clean|fossil clean]" that works the same as "--dry-run", so that the name does not collide with the --dry-run option of "fossil all". * Provide a configuration option to show dates on the web timeline as "YYMMMDD HH:MM" * Add an option to the "stats" webpage that allows an administrator to see the current repository schema. * Enhancements to the "[/help?cmd=/vdiff|/vdiff]" webpage for more difference display options. * Added the "[/tree?ci=trunk&expand | /tree]" webpage as an alternative to "/dir" and make it the default way of showing file lists. * Send gzipped HTTP responses to clients that support it. <h2>Changes For Version 1.27 (2013-09-11)</h2> * Enhance the [/help?cmd=changes | fossil changes], [/help?cmd=clean | fossil clean], [/help?cmd=extras | fossil extras], [/help?cmd=ls | fossil ls] and [/help?cmd=status | fossil status] commands to restrict operation to files and directories named on the command-line. * New --integrate option to [/help?cmd=merge | fossil merge], which automatically closes the merged branch when committing. * Renamed <tt>/stats_report</tt> page to [/reports]. Graph width is now relative, not absolute. * Added <tt>yw=YYYY-WW</tt> (year-week) filter to timeline to limit the results to a specific year and calendar week number, e.g. [/timeline?yw=2013-01]. * Updates to SQLite to prevent opening a repository file using file descriptors 1 or 2 on Unix. This fixes a bug under which an assertion failure could overwrite part of a repository database file, corrupting it. * Added support for unlimited line lengths in side-by-side diffs. * New --close option to [/help?cmd=commit | fossil commit], which immediately closes the branch being committed. * Added <tt>chart</tt> option to [/help?cmd=bisect | fossil bisect]. * Improvements to the "human or bot?" determination. * Reports errors about missing CGI-standard environment variables for HTTP servers which do not support them. * Minor improvements to sync support on Windows. * Added <tt>--scgi</tt> option to [/help?cmd=server | fossil server]. * Internal improvements to the sync process. * The internals of the JSON API are now MIT-licensed, so downstream users/packagers are no longer affected by the "do no evil" license clause. <h2>Changes For Version 1.26 (2013-06-18)</h2> * The argument to the --port option for the [/help?cmd=ui | fossil ui] and [/help?cmd=server | fossil server] commands can take an IP address in addition to the port number, causing Fossil to bind to just that one IP address. * After prompting for a password, also ask if that password should be remembered. * Performance improvements to the diff engine. * Fix the side-by-side diff engine to work better with multi-byte Unicode text. * Color-coding in the web-based annotation (blame) display. Fix the annotation engine so that it is no longer confused by time-warps. * The markdown formatter is now available by default and can be used for tickets, wiki, and embedded documentation. * Add subcommands "fossil bisect log" and "fossil bisect status" to the [/help?cmd=bisect | fossil bisect] command, as well as other bisect enhancements. * Enhanced defenses that prevent spiders from using excessive CPU and bandwidth. * Consistent use of the -n or --dry-run command line options. * Win32: Fossil now understands Cygwin paths containing one or more of the characters <nowiki>"*:<>?|</nowiki>. Those are normally forbidden in win32. This means that the win32 fossil.exe is better usable in a Cygwin environment. See [http://cygwin.com/cygwin-ug-net/using-specialnames.html#pathnames-specialchars]. * Cygwin: Fossil now understands win32 absolute paths starting with a drive letter everywhere. The default value of the "case-sensitive" setting is now FALSE, except when case-sensitivity is enabled in the Windows kernel. See [http://cygwin.com/cygwin-ug-net/using-specialnames.html#pathnames-casesensitive] * Enhancements to /timeline.rss, adding more flags for filtering results, including the ability to subscribe to changes made to individual tickets. For example: [/timeline.rss?y=t&tkt=12fceeec82]. * Improved handling of the differences between case-sensitive and case-insensitive filesystems. * JSON API: added the 'status' command to report local checkout status. * Fixes to the <tt>--args</tt> support and documented this feature in the help. * Added [/stats_report] page. * Added <tt>ym=YYYY-MM</tt> filter to the [/timeline?ym=2013-06]. * Fixed: <tt>config reset</tt> now re-installs default ticket report format. * <tt>ssh://</tt> and <tt>file://</tt> protocols now ignore proxy settings. * Added [/hash-color-test] web page. * Cherry-pick merges are recorded internally (though no yet displayed on the timeline graph.) * Bring in the latest versions of SQLite, zlib, and autosetup from upstream. <h2>Changes For Version 1.25 (2013-02-16)</h2> * Enhancements to ticket processing. There are now two tables: TICKET and TICKETCHNG. There is one row in TICKETCHNG for each ticket artifact. Fields from ticket artifacts go into either or both of TICKET and TICKETCHNG, whichever contain matching column names. Default ticket edit and viewing scripts are updated to use TICKETCHNG. The TH1 scripting language is enhanced to support this, including the new "query" command for doing SQL queries against the repository database. All changes should be backwards compatible. * Add the ability to moderate ticket and wiki changes. Unmoderated changes do not sync and may be deleted by the moderator if found to contain spam or other objectionable content. * Add javascript so that clicking on a node of the timeline graph selects that node. Then clicking on a second node shows a diff between the two nodes. Clicking on the selected node unselects it. * Warn of unresolved merge conflicts in "fossil status" and disallow commits of unresolved conflicts unless the --allow-conflict option is used. * Add javascript so that clicking on column headers in a ticket report sorts by the indicated column. * Add the "fossil cat" command which is basically an alias for "fossil finfo -p". * Hyperlinks with the class "button" are rendered as submenu buttons on embedded documentation. * The check-in comment editor on Windows now defaults to NotePad.exe. * Correctly deal with BOMs in check-in comments. Also attempt to convert check-in comments to UTF8 from other encodings. * Allow the deletion of multiple stash entries using multiple arguments to the "fossil stash rm" command. * Enhance the "fossil server DIRECTORY" command to serve static content files contained in DIRECTORY. For security, only files with a recognized suffix (such as *.html, *.jpg, *.txt, etc) will be delivered as static content, and *.fossil files are not on the list of recognized suffixes. There are additional restrictions on the names of the files. * Allow the "fossil ui" command to specify a directory as long as the the --notfound option is used. * Add a configuration option that causes timeline messages to be rendered as text/x-fossil-plain (which is the same as text/plain except that hyperlinks inside of <nowiki>[...]</nowiki> are decorated.) * Only decorate <nowiki>[...]</nowiki> in check-in comments and tickets if the contented text really is a valid hyperlink target. * Improvements to the side-by-side diff algorithm, for a more human-friendly display in some complex cases. * Added <nowiki>[utime] and [stime]</nowiki> commands to TH1. These commands can be used for things such as displaying the page rendering time in the footer. * Add the ability to pass command-line options of "fossil rebuild" to "fossil all rebuild". * Add the --deanalyze option to "fossil rebuild" (and "fossil all rebuild") * Do not run the graphical merging tool nor leave merge-droppings after a dry-run merge. Display an improved merge-summary message at the end of the merge. * Add options to "fossil commit" to override the various sanity checks. Options added: --allow-empty, --allow-fork, --allow-older, and --allow-conflict. * Optionally require a CAPTCHA (controlled by a setting on the Admin/Access webpage) when a user who is not logged in tries to edit wiki, or a ticket, or an attachment. * Improvements to the "ssh://" sync protocol, to help it move past noisy motd comments. * Add the uf=FILE-SHA1-HASH query parameter to the timeline, causing the timeline to show only check-ins that contain the specific file identified by FILE-SHA1-HASH. ("uf" stands for "uses file".) * Enhance the file change annotator so that it follows the file across name changes. * Fix the server-side of the sync protocol so that it will not generate a delta loop when a file changes from its original state, through two or more intermediate states, and back to the original state, all within a single sync. * Show much less output during a sync operation, unless the --verbose option is used. * Set the action= attribute of <form> elements using javascript, as an addition defense against spam-bots. * Disallow invalid UTF8 characters (such as characters in the surrogate pair range) in filenames. * Judge the UserAgent strings issued by the NetSurf webbrowser to be coming from a human, not from a bot. * Add the zlib sources to the Fossil source tree (under compat/zlib) and use those sources when compiling on (Windows) systems that do not have a zlib library installed by default. * Prompt the user with the option to convert non-UTF8 files into UTF8 when committing. * Allow the characters <nowiki>*[]?</nowiki> in filenames. * Allow the --context option on diff commands to have a value of 0. * Added the "dbstat" command. * Enhanced "fossil merge" so that if the VERSION argument is omitted, Fossil tries to merge any forks of the current branch. * Improved detection of forks in a commit race. * Added the --analyze option to "fossil rebuild". <h2>Changes For Version 1.24 (2012-10-22)</h2> * Added support for WYSIWYG editing of wiki pages. WYSIWYG is turned off by default and can be turned on by setting a configuration option. * Allow style= attribute to occur in HTML markup on wiki pages. * Added the --tk option to the "fossi diff" and "fossil stash diff" commands, causing color-coded diff output to be displayed in a Tcl/Tk GUI window. This option only works if Tcl/Tk is installed on the host. * On Windows, make the "gdiff" command default to use WinDiff.exe. * Update the "fossil stash" command so that it always prompts for a comment if the -m option is omitted. * Enhance the timeline webpages so that a=, b=, c=, d=, p=, and dp= query parameters (and others) can all accept any valid check-in name (such as branch names or labels) instead of just SHA1 hashes. * Added the "fossil stash show" command. * Added the "fileage" webpage with links to this page from the check-in information page and from the file browser. * Added --age and -t options to the "fossil ls" command. * Added the --setmtime option to "fossil update". When used, the mtime of all managed files is set to the time when the most recent version of the file was checked in. * Changed the "vdiff" webpage to show the complete text of files that were added or removed (the equivalent of using the -N or --newfile options with the "fossil diff" command-line.) * Added the --temp option to "fossil clean" and "fossil extra", causing those commands to only look at temporary files generated by Fossil, such as merge-conflict reports or aborted check-in messages. * Enhance the raw page download so that it can guess the mimetype of attachments based on the filename. * Change the behavior of the from= and to= query parameters on the timeline page so that by default the path between the two specified check-ins avoids merges. * Add the --baseurl option to "fossil server" and "fossil http" commands, so that those commands can be used with reverse proxies. * If unable to determine the command-line user, do not guess. Instead issue an error message. This helps prevent check-ins from accidentally occurring under the wrong username. * Include branch information in the output of file change listings (the "finfo" webpage). * Make the simplified view of file history, rather than the full view, the default. * In the "fossil configuration" command, allow the "css" option for synchronizing, importing, or exporting just the CSS file. This makes it easier to share CSS files across repositories by exporting from one and importing to another. * Add the (unsupported) "fossil test-orphans" command. * Add the --template option to the "fossil init" command, to facilitate creating new repositories based on a template repository. * Add the diff-binary setting, which if enabled causes binary files to be passed to the "gdiff" command for it to deal with, rather than simply printing a "cannot diff binary files" error. * Add the --unified option to the "fossil diff" command to force a unified diff even if the --tk option (which normally implies a side-by-side diff) is used. * Present a choice of nearby branches and versions to diff against on the check-in information page. * Add the --force option to the "fossil merge" command that will force the merge to occur even if it would be a no-op. This is sometimes useful for documentation purposes. * Add another built-in skin: "Enhanced Default". Other minor tweaks to the existing skins. * Add the "urllist" webpage, showing a list of URLs by which a server instance of Fossil has been accessed. Requires "Administrator" privileges. A link is on the "Setup" main page. * Enable dynamic loading of the Tcl runtime for installations that want to use Tcl as part of their configuration. This reduces the size of the Fossil binary and allows any version of Tcl 8.4 or later to be used. * Merge the latest SQLite changes from upstream. * Lots of minor bug fixes. <h2>Changes For Version 1.23 (2012-08-08)</h2> * The default checkout database name is now ".fslckout" instead of "_FOSSIL_" on Unix. Both names continue to work. * Added the "fossil all changes" command * Added the --ckout option to the "fossil all list" command * Added the "public-pages" glob pattern that can be configured to allow anonymous users to see embedded documentation on sites where source code should not be accessible to anonymous users. * Allow multiple --tag options on the same "fossil commit" command. * Change the meaning of the --bgcolor option for "fossil commit" to only change the color for that one commit. The new --branchcolor option is available to set a persistent background color. * Add the branch= query parameter to the vdiff page and the --branch option to the "fossil diff" command. * Check-in names of the form "root:BRANCH" now refer to the origin of the branch. Hence to see all changes in a branch, use "fossil diff --from root:BRANCH --to BRANCH". The --branch option on the diff command is an alias for the same. * Add the ability to configure ad-units to be displayed between the menu bar and the content. * Add the ability to set a background image as part of server configuration. * Allow partial commits of cherrypick merges. * Updates against an uncommitted merge are now a warning, not a fatal error. * Prompt the user to continue if a check-in comment is unedited. * Fixes to case sensitivity settings with the /dir webpage. * Repositories now try to remember the locations of all checkouts and web-access URLs and display this information with the "fossil info $REPO" command. * Improved defense against spiders: The src= attribute of <a> elements is set using javascript after the page loads. * Enhanced formatting of the user list page. * If a file named in "fossil add" is missing, that is now a warning instead of a fatal error. * Fix side-by-side diff so that it displays correctly with multi-byte UTF8 characters. * Performance improvements in the diff logic. * Other performance tweaks and documentation updates. <h2>Changes For Version 1.22 (2012-03-17)</h2> * Greatly improved "diff" processing including the new --brief option, partial line matching, colorized in-line diffs, and better performance. * Promote "allow-symlinks" to a versionable setting * Harden the CGI processing logic against DOS attacks * Add the ability to run TH1 scripts after sync requests * Store the repository name in _FOSSIL_ as it is type in the "open" command, possibly as a relative pathname. * Make ".fslckout" the alternative name for the "_FOSSIL_" file. * Change the "ssh:" transfer method to allow all access regardless of user permission. * Improvements to the timeline messages associated with tag changes. (Requires a "[/help/rebuild | fossil rebuild]" to take effect.) * Various additions and fixes for the JSON API. * Improved merge-with-rename handling. * --cherrypick merges use their origin's commit message by default. * Added support for multiple concurrent logins per user. * Update to use SQLite version 3.7.11. * Various minor bug fixes. <h2>Changes For Version 1.21 (2011-12-13)</h2> * Added side-by-side diffs in the command-line interface * Automatically enable hyperlinks if the UserAgent string in the HTTP header suggests that the requestor is a human and not a bot. * Show only commonly used commands with "fossil help". Use "fossil help --all" to see the complete list now. * Improvements to the "stash" command: (1) Stash all files, not just those below the working directory. (2) Add the --detail option to "list". (3) Confirm before "drop --all". (4) Add the "help" subcommand. * Add an Admin/Access setting to change the number of octets of the IP address that are saved in login cookies - allowing this setting to be changed to zero * Promote the "test-md5sum" command to "md5sum". * Added the "whatis" command. * Stop showing the server-code in status outputs - it is no longer used for anything. * Added a compile-time option (--with-tcl) to build in full Tcl scripting support via integration with TH1. * Merged the JSON branch into trunk. Disabled by default. Enabled by a compile-time option. Probably it will be enabled by default in some future release. * Update to use SQLite version 3.7.9 plus the alignment fix for Sparc. align <h2>Changes For Version 1.20 (2011-10-21)</h2> * Added side-by-side diffs in HTML interface.

The check-in will go onto the desired branch. → Check-ins to trunk normally require approval from the lead programmer (drh). 4. auto-sync is on, or the system clock is verified 5. If sources files have been added or removed, ensure all makefiles and configure scripts have been updated accordingly. Before every check-in to <b>trunk</b>: 6. No compiler warnings on the development machine. 7. The fossil executable that results from a build actually works. <hr> <h2>Commentary</h2> Before you go ahead and push content back to the servers, make sure that the username you are using by default matches your username within the project. Also remember to enable the localauth setting if you intend to make changes via a locally served web UI. Item 1 is the most important step. Consider using <b>gdiff</b> instead of <b>diff</b> if you have a graphical differ configured. Or use the command-line option <b>--tk</b>. Also consider the <b>-N</b> command-line option to show the complete text newly added files. The recommended command for completing checklist item 1 is: <b>fossil diff --tk -N</b> Look carefully at every changed line in item 1. Make sure that you are not about to commit unrelated changes. If there are two or more unrelated changes present, consider breaking up the commit into two or more separate commits. Always make 100% sure that all changes are compatible with the BSD license, that you have the authority to commit the code in accordance with the [/doc/trunk/www/copyright-release.html | CLA] that you have signed and have on file, and that no NDAs, copyrights, patents, or trademarks are infringed by the check-in. Also check very carefully to make sure that you are not introducing security vulnerabilities. Pay particular attention to the possibility of SQL or HTML injection attacks. Item 2 verifies that you have not added source files but failed to do the necessary "<b>fossil add</b>" to manage them. If you commit without bringing the new file under source control, the check-in will be broken. That, in turn, can cause complications far in the future when we are bisecting for a bug. For item 3, Run "<b>fossil status</b>" or the equivalent to make sure your changes are going into the branch you think they are. Also double-check the branch name when entering change comments. Never check into trunk unless you are expressly authorized to do so. For Item 4, if you are on-network, make sure auto-sync is enabled. This will minimize the risk of an unintended fork. It will also give you a warning if you system clock is set incorrectly. If you are off-network, make sure that your system clock is correct or at least close to correct so that your check-in does not appear out-of-sequence on timelines. On-network commits are preferred, especially for trunk commits. Items 6 and 7 help to ensure that check-ins on the trunk always work. Knowing that the trunk always works makes bisecting much easier. Items 6 and 7 are recommended for all check-ins, even those that are on a branch. But they are especially important for trunk check-ins. We desire that all trunk check-ins work at all times. Any experimental, unstable, or questionable changes should go on a branch and be merged into trunk after further testing. |

The bold term of the pathname is a check-in name that determines which version of the documentation to display. Fossil provides a variety of ways to specify a check-in. This document describes the various methods. <h2 id="canonical">Canonical Check-in Name</h2> The canonical name of a check-in is the hash of its [./fileformat.wiki#manifest | manifest] expressed as a 40-or-more character lowercase hexadecimal number. For example: <blockquote><pre> fossil info e5a734a19a9826973e1d073b49dc2a16aa2308f9 </pre></blockquote> The full 40+ character hash is unwieldy to remember and type, though, so Fossil also accepts a unique prefix of the hash, using any combination of upper and lower case letters, as long as the prefix is at least 4 characters long. Hence the following commands all accomplish the same thing as the above: <blockquote><pre> fossil info e5a734a19a9 fossil info E5a734A fossil info e5a7 </blockquote> Many web-interface screens identify check-ins by 10- or 16-character prefix of canonical name. <h2 id="tags">Tags And Branch Names</h2> Using a tag or branch name where a check-in name is expected causes Fossil to choose the most recent check-in with that tag or branch name. So, for example, as of this writing the most recent check-in that is tagged with "release" is [d0753799e44]. So the command: |
︙ | ︙ | |||
97 98 99 100 101 102 103 104 105 106 107 108 109 110 111 112 113 114 115 | check-in is the most recent so it is the one that is selected. Note that unlike other command DVCSes, a "branch" in Fossil is not anything special; it is simply a sequence of check-ins that share a common tag. So the same mechanism that resolves tag names also resolves branch names. Note also that there can (in theory) be an ambiguity between tag names and canonical names. Suppose, for example, you had a check-in with the canonical name deed28aa99a835f01fa06d5b4a41ecc2121bf419 and you also happened to have tagged a different check-in with "deed2". If you use the "deed2" name, does it choose the canonical name or the tag name? In such cases, you can prefix the tag name with "tag:". For example: <blockquote><tt> fossil info tag:deed2 </tt></blockquote> | > | > > > > > > > > > > > > > > > > > > > > > | | | | > > > > > | | > > > > > | | | | > > > > > > > > > | | | > > > > > > > > > > > > > > > > > > > > | > > | > > > | > > > > > | | | > > > > > > > > | > > > > > > > > > > > > > > > > > > | 98 99 100 101 102 103 104 105 106 107 108 109 110 111 112 113 114 115 116 117 118 119 120 121 122 123 124 125 126 127 128 129 130 131 132 133 134 135 136 137 138 139 140 141 142 143 144 145 146 147 148 149 150 151 152 153 154 155 156 157 158 159 160 161 162 163 164 165 166 167 168 169 170 171 172 173 174 175 176 177 178 179 180 181 182 183 184 185 186 187 188 189 190 191 192 193 194 195 196 197 198 199 200 201 202 203 204 205 206 207 208 209 210 211 212 213 214 215 216 217 218 219 220 221 222 223 224 225 226 227 228 229 230 231 232 233 234 235 236 237 238 239 240 241 242 243 244 245 246 247 248 249 250 251 252 253 254 255 256 257 258 259 260 261 262 263 264 265 266 267 268 269 270 271 272 273 274 275 276 277 278 279 280 281 282 283 284 285 286 287 288 289 290 291 292 293 294 295 | check-in is the most recent so it is the one that is selected. Note that unlike other command DVCSes, a "branch" in Fossil is not anything special; it is simply a sequence of check-ins that share a common tag. So the same mechanism that resolves tag names also resolves branch names. <a id="tagpfx"></a> Note also that there can (in theory) be an ambiguity between tag names and canonical names. Suppose, for example, you had a check-in with the canonical name deed28aa99a835f01fa06d5b4a41ecc2121bf419 and you also happened to have tagged a different check-in with "deed2". If you use the "deed2" name, does it choose the canonical name or the tag name? In such cases, you can prefix the tag name with "tag:". For example: <blockquote><tt> fossil info tag:deed2 </tt></blockquote> The "tag:deed2" name will refer to the most recent check-in tagged with "deed2" not to the check-in whose canonical name begins with "deed2". <h2 id="whole-branches">Whole Branches</h2> Usually when a branch name is specified, it means the latest check-in on that branch. But for some commands (ex: [/help/purge|purge]) a branch name on the argument means the earliest connected check-in on the branch. This seems confusing when being explained here, but it works out to be intuitive in practice. For example, the command "fossil purge XYZ" means to purge the check-in XYZ and all of its descendants. But when XYZ is in the form of a branch name, one generally wants to purge the entire branch, not just the last check-in on the branch. And so for this reason, commands like purge will interpret a branch name to be the first check-in of the branch rather than the last. If there are two or more branches with the same name, then these commands will select the first check-in of the branch that has the most recent check-in. What happens is that Fossil searches for the most recent check-in with the given tag, just as it always does. But if that tag is a branch name, it then walks back down the branch looking for the first check-in of that branch. Again, this behavior only occurs on a few commands where it make sense. <h2 id="timestamps">Timestamps</h2> A timestamp in one of the formats shown below means the most recent check-in that occurs no later than the timestamp given: 1. <i>YYYY-MM-DD</i> 2. <i>YYYY-MM-DD HH:MM</i> 3. <i>YYYY-MM-DD HH:MM:SS</i> 4. <i>YYYY-MM-DD HH:MM:SS.SSS</i> 5. <i>YYYYMMDD</i> 6. <i>YYYYMMDDHHMM</i> 7. <i>YYYYMMDDHHMMSS</i> In the second through the fourth forms, the space between the day and the year can optionally be replaced by an uppercase <b>T</b> and the entire timestamp can optionally be followed by "<b>z</b>" or "<b>Z</b>". In the fourth form with fractional seconds, any number of digits may follow the decimal point, though due to precision limits only the first three digits will be significant. The final three pure-digit forms without punctuation are only valid if the number they encode is not also the prefix of an artifact hash. In its default configuration, Fossil interprets and displays all dates in Universal Coordinated Time (UTC). This tends to work the best for distributed projects where participants are scattered around the globe. But there is an option on the Admin/Timeline page of the web-interface to switch to local time. The "<b>Z</b>" suffix on a timestamp check-in name is meaningless if Fossil is in the default mode of using UTC for everything, but if Fossil has been switched to local time mode, then the "<b>Z</b>" suffix means to interpret that particular timestamp using UTC instead of local time. You may prefix a timestamp with the string “date:â€, in which case processing stops immediately, whether the string is parsed correctly and refers to anything within the repository or not. The prefix is therefore useful when the date could be misinterpreted as a tag. For example, a repo could have release tags like “2020-04-01â€, the date the release was cut, but you could force Fossil to interpret that string as a date rather than as a tag by passing “date:2020-04-01â€. For an example of how timestamps are useful, consider the homepage for the Fossil website itself: <blockquote> http://www.fossil-scm.org/fossil/doc/<b>trunk</b>/www/index.wiki </blockquote> The bold component of that URL is a check-in name. To see what the Fossil website looked like on January 1, 2009, one has merely to change the URL to the following: <blockquote> http://www.fossil-scm.org/fossil/doc/<b>2009-01-01</b>/www/index.wiki </blockquote> <h2 id="tag-ts">Tag And Timestamp</h2> A check-in name can also take the form of a tag or branch name followed by a colon and then a timestamp. The combination means to take the most recent check-in with the given tag or branch which is not more recent than the timestamp. So, for example: <blockquote> fossil update trunk:2010-07-01T14:30 </blockquote> Would cause Fossil to update the working check-out to be the most recent check-in on the trunk that is not more recent that 14:30 (UTC) on July 1, 2010. <h2 id="root">Root Of A Branch</h2> A branch name that begins with the "<tt>root:</tt>" prefix refers to the last check-in in the parent branch prior to the beginning of the branch. Such a label is useful, for example, in computing all diffs for a single branch. The following example will show all changes in the hypothetical branch "xyzzy": <blockquote> fossil diff --from root:xyzzy --to xyzzy </blockquote> <a id="merge-in"></a> A branch name that begins with the "<tt>merge-in:</tt>" prefix refers not to the root of the branch, but to the most recent merge-in for that branch from its parent. The most recent merge-in is the version to diff the branch against in order to see all changes in just the branch itself, omitting any changes that have already been merged in from the parent branch. <h2 id="special">Special Tags</h2> The tag "tip" means the most recent check-in. The "tip" tag is roughly equivalent to the timestamp tag "5000-01-01". This special name works anywhere you can pass a "NAME", such as in in <tt>/info</tt> URLs: <blockquote><pre> http://localhost:8080/info/tip </pre></blockquote> There are several other special names, but they only work from within a check-out directory because they are relative to the current checked-out version: * "current": the current checked-out version * "next": the youngest child of the current checked-out version * "previous" or "prev": the primary (non-merge) parent of "current" Therefore, you can use these names in a <tt>fossil info</tt> command, but not in an <tt>/info</tt> URL, for example. For embedded documentation URLs only, there is one more special name, "ckout". See [./embeddeddoc.wiki#ckout | its coverage elsewhere] for more details. You cannot currently use "ckout" anywhere other than in <tt>/doc</tt> URLs. <h2 id="examples">Additional Examples</h2> To view the changes in the most recent check-in prior to the version currently checked out: <blockquote><pre> fossil diff --from previous --to current </pre></blockquote> Suppose you are of the habit of tagging each release with a "release" tag. Then to see everything that has changed on the trunk since the last release: <blockquote><pre> fossil diff --from release --to trunk </pre></blockquote> <h2 id="order">Resolution Order</h2> Fossil currently resolves name strings to artifact hashes in the following order: # Exact matches on [#special | the special names] # [#timestamps | Timestamps], with preference to ISO8601 forms # [#tagpfx | tag:TAGNAME] # [#root | root:BRANCH] # [#merge-in | merge-in:BRANCH] # [#tag-ts | TAG:timestamp] # Full artifact hash or hash prefix. # Any other type of symbolic name that Fossil extracts from blockchain artifacts. <div style="height:40em" id="this-space-intentionally-left-blank"></div> |

Such a policy helps to promote a cohesive design for a cathedral-style project run by a small cliche of developers - the sort of project for which Fossil was designed. But sometimes it is desirable to branch off a side project that does not sync back to the master but does continue to track changes in the master. For example, the master project might be an open-source project like [https://www.sqlite.org/|SQLite] and a team might want to do a proprietary closed-source enhancement to that master project in a separate repository. All changes in the master project should flow forward into the derived project, but care must be taken to prevent proprietary content from the derived project from leaking back into the master. <h2>Child Projects</h2> A scenario such as the above can be accomplished in Fossil by creating a child project. The child project is able to freely pull from the parent, but the parent cannot push or pull from the child nor is the child able to push to the parent. Content flows from parent to child only, and then only at the request of the child. <h2>Creating a Child Project</h2> To create a new child project, first clone the parent. Then make manual SQL changes to the child repository as follows: <blockquote><verbatim> UPDATE config SET name='parent-project-code' WHERE name='project-code'; UPDATE config SET name='parent-project-name' WHERE name='project-name'; INSERT INTO config(name,value) VALUES('project-code',lower(hex(randomblob(20)))); INSERT INTO config(name,value) VALUES('project-name','CHILD-PROJECT-NAME'); </verbatim></blockquote> Modify the CHILD-PROJECT-NAME in the last statement to be the name of the child project, of course. The repository is now a separate project, independent from its parent. Clone the new project to the developers as needed. The child project and the parent project will not normally be able to sync with one another, since they are now separate projects with distinct project codes. However, if the "--from-parent-project" command-line option is provided to the "[/help?cmd=pull|fossil pull]" command in the child, and the URL of parent repository is also provided on the command-line, then updates to the parent project that occurred after the child was created will be added to the child repository. Thus, by periodically doing a pull --from-parent-project, the child project is able to stay up to date with all the latest changes in the parent. |

Most commonly, you run Fossil as root to allow it to bind to TCP port 80 for HTTP service, since normal users are restricted to ports 1024 and up on OSes where this behavior occurs. Fossil uses the owner of the Fossil repository file as its new user ID when dropping root privileges. When this happens, Fossil needs to have all of its dependencies inside the chroot jail in order to continue work. There are several things you typically need in order to make things work properly: * the repository file(s) * `/dev/null` — create it with `mknod(8)` inside the jail directory ([Linux example][mnl], [OpenBSD example][obsd]) * `/dev/urandom` — ditto * `/proc` — you might need to mount this virtual filesystem inside the jail on Linux systems that make use of [Fossil’s server load shedding feature][fls] * any shared libraries your `fossil` binary is linked to, unless you [configured Fossil with `--static`][bld] to avoid it Fossil does all of this in order to protect the host OS. You can make it bypass the jail part of this by passing <tt>--nojail</tt> to <tt>fossil server</tt>, but you cannot make it skip the dropping of root privileges, on purpose.

There are many such systems in use today. Fossil strives to distinguish itself from the others by being extremely simple to setup and operate. This document is intended as a quick introduction to the concepts behind Fossil. See also: * [./whyusefossil.wiki#definitions|Definitions] * [./quickstart.wiki|Quick start guide] <h2>2.0 Composition Of A Project</h2> <img src="concept1.gif" align="right" hspace="10"> A software project normally consists of a "source tree". A source tree is a hierarchy of files that are used to generate the end product. The source tree changes over time as the software grows and expands and as features are added and bugs are fixed. A snapshot of the source tree at any point in time is called a "version" or "revision" or a "baseline" of the product. In Fossil, we use the name "check-in". A "repository" is a database that contains copies of all historical check-ins for a project. Check-ins are normally stored in the repository in a highly space-efficient compressed format (delta encoding). But that is an implementation detail that you the user need not worry over. Think of the repository as a safe place where all your old check-ins are securely stored away and available for retrieval whenever you need them. A repository in Fossil is a single file on your disk. This file might be rather large (dozens or hundreds of megabytes for a large or long running project) but it is nevertheless just a file. You can move it around, rename it, write it out to a memory stick, or do anything else you normally do with files. Each source tree that is controlled by Fossil is associated with a single repository on the local disk drive. You can tie two or more source trees to a single repository if you want (though one tree per repository is the most common configuration.) So a single repository can be associated with many source trees, but each source tree is associated with only one repository. Fossil source trees may not overlap. A Fossil source tree is identified by a file named "_FOSSIL_" (or ".fslckout", but this article will always use the name "_FOSSIL_") in the root directory of the source tree. Every file that is a sibling of _FOSSIL_ and every file in every subfolder is considered potentially a part of the source tree. The _FOSSIL_ file contains (among other things) the pathname of the repository with which the source tree is associated. On the other hand, the repository has no record of its source trees. So you are free to delete a source tree or move it around without consequence. But if you move or rename or delete a repository, then any source trees associated with that repository |

Each artifact has a universally unique name which is the <a href="http://en.wikipedia.org/wiki/SHA1">SHA1</a> or <a href="http://en.wikipedia.org/wiki/SHA3">SHA3-256</a> hash of the content of that file expressed as either 40 or 64 characters of lower-case hexadecimal. (See the [./hashpolicy.wiki|hash policy document] for information on which algorithm is used, when.) Such a hash is referred to as the Artifact ID. These hash algorithms were created with Fossil's purpose in mind: to provide a highly forgery-resistant identifier for a blob of data, such as a file. Given any file, it is simple to find the artifact ID for that file. But given an artifact ID, it is computationally intractable to generate a file that will have that same artifact ID. Artifact IDs look something like this: <blockquote><b> 6089f0b563a9db0a6d90682fe47fd7161ff867c8<br> 59712614a1b3ccfd84078a37fa5b606e28434326<br> 19dbf73078be9779edd6a0156195e610f81c94f9<br> b4104959a67175f02d6b415480be22a239f1f077<br> 997c9d6ae03ad114b2b57f04e9eeef17dcb82788 </b></blockquote> When referring to an artifact using Fossil, you can use a unique prefix of the artifact ID that is four characters or longer. This saves a lot of typing. When displaying artifact IDs, Fossil will usually only show the first 10 digits since that is normally enough to uniquely identify a file. Changing (or adding or removing) a single byte in a file results in a completely different artifact ID. And since the artifact ID is the name of the artifact, making any change to a file results in a new artifact. In this way, artifacts are immutable. |

The manifest is a listing of all other files in that source tree. The manifest contains the (complete) artifact ID of the file and the name of the file as it appears on disk, and thus serves as a mapping from artifact ID to disk name. The artifact ID of the manifest is the identifier for the entire check-in. When you look at a "timeline" of changes in Fossil, the ID associated with each check-in or commit is really just the artifact ID of the manifest for that check-in. <p>The manifest file is not normally a real file on disk. Instead, the manifest is computed in memory by Fossil whenever it needs it. However, the "fossil setting manifest on" command will cause the manifest file to be materialized to disk, if desired. Both Fossil itself, and SQLite cause the manifest file to be materialized to disk so that the makefiles for these project can read the manifest and embed version information in generated binaries. <p>Fossil automatically generates a manifest whenever you "commit" a new check-in. So this is not something that you, the developer, need to worry with. The format of a manifest is intentionally designed to be simple to parse, so that if you want to read and interpret a manifest, either by hand or with a script, that is easy to do. But you will probably never need to do so.</p> |

The implementation of Fossil is in the form of a single executable named "fossil" (or "fossil.exe" on Windows). To install Fossil on your system, all you have to do is obtain a copy of this one executable file (either by downloading a <a href="https://www.fossil-scm.org/fossil/uv/download.html">pre-compiled version</a> or [./build.wiki | compiling it yourself]) and then putting that file somewhere on your PATH. Fossil is completely self-contained. It is not necessary to install any other software in order to use Fossil. You do <u>not</u> need CVS, gzip, diff, rsync, Python, Perl, Tcl, Java, Apache, PostgreSQL, MySQL, SQLite, patch, or any similar software on your system in order to use Fossil effectively. You will want to have some kind of text editor for entering check-in comments. Fossil will use whatever text editor is identified by your VISUAL environment variable. Fossil will also use GPG to clearsign your manifests if you happen to have it installed, but Fossil will skip that step if GPG missing from your system. You can optionally set up Fossil to use external "diff" programs, though Fossil has an excellent built-in "diff" algorithm that works fine for most people. If you happen to have Tcl/Tk installed on your system, Fossil will use it to generate a graphical "diff" display when you use the --tk option to the "diff" command, but this too is entirely optional. To uninstall Fossil, simply delete the executable. To upgrade an older version of Fossil to a newer version, just replace the old executable with the new one. You might need to run "<b>fossil all rebuild</b>" to restructure your repositories after an upgrade. Running "all rebuild" never hurts, so when upgrading it is a good policy to run it even if it is not strictly necessary. To use Fossil, simply type the name of the executable in your shell, followed by one of the various built-in commands and arguments appropriate for that command. For example: <blockquote><b> fossil help </b></blockquote> In the next section, when we say things like "use the <b>help</b> command" we mean to use the command name "help" as the first token after the name of the Fossil executable, as shown above. <a name="workflow"></a> <h2>4.0 Workflow</h2> <img src="concept2.gif" align="right" hspace="10" style="max-width:50%;"> Fossil has two modes of operation: <i>"autosync"</i> and <i>"manual-merge"</i> Autosync mode is reminiscent of CVS or SVN in that it automatically keeps your changes in synchronization with your co-workers through the use of a central server. The manual-merge mode is the standard workflow for GIT or Mercurial in that your local repository develops independently of your coworkers and you share and merge your changes manually. An interesting feature of Fossil is that it supports both autosync and manual-merge work flows. The default setting for Fossil is to be in autosync mode. You can change the autosync setting or check the current autosync setting using commands like: <blockquote> <b>fossil setting autosync on<br> fossil setting autosync off<br> <b>fossil settings</b> </blockquote> By default, Fossil runs with autosync mode turned on. The authors finds that projects run more smoothly in autosync mode since autosync helps to prevent pointless forking and merging and helps keeps all collaborators working on exactly the same code rather than on their own personal forks of the code. In the author's view, manual-merge mode should be reserved for disconnected operation. <h3>4.1 Autosync Workflow</h3> <ol> <li> Establish a local repository using either the <b>new</b> command to start a new project, or the <b>clone</b> command to make a clone of a repository for an existing project. </li> <li> Establish one or more source trees using the <b>open</b> command with the name of the repository file as its argument. </li> <li> The <b>open</b> command in the previous step populates your local source tree with a copy of the latest check-in. Usually this is what you want. In the rare cases where it is not, use the <b>update</b> command to switch to a different check-in. Use the <b>timeline</b> or <b>leaves</b> commands to identify alternative check-ins to switch to. </li> <li> Edit the code. Add new files to the source tree using the <b>add</b> command. Omit files from future check-ins using the <b>rm</b> command. (Even when you remove files from future check-ins, those files continue to exist in historical check-ins.) Test your changes. </li> <li> Create a new check-in using the <b>commit</b> command. You will be prompted for a check-in comment and also for your GPG key if you have GPG installed. The commit copies the edits you have made in your local source tree into your local repository. After your commit completes, Fossil will automatically <b>push</b> your changes back to the server you cloned from or whatever server you most recently synced with. </li> <li> When your coworkers make their own changes, you can merge those changes into your local local source tree using the <b>update</b> command. In autosync mode, <b>update</b> will first go back to the server you cloned from or with which you most recently synced, and pull down all recent changes into your local repository. Then it will merge recent changes into your local source tree. If you do an <b>update</b> and find that it messes something up in your source tree (perhaps a co-worker checked in incompatible changes) you can use the <b>undo</b> command to back out the changes. </li> <li> Repeat all of the above until you have generated great software. </li> </ol> |

This document details certain specific CSS tweaks which users have asked about via the forums. This is a "living document" - please feel free to suggest additions via [the Fossil forum](https://fossil-scm.org/forum/). This document is *not* an introduction to CSS - the web is full of tutorials on that topic. It covers only the specifics of customizing certain CSS-based behaviors in a Fossil UI. That said... ## Is it Really `!important`? By and large, CSS's `!important` qualifier is not needed when customzing Fossil's CSS. On occasion, however, particular styles may be set directly on DOM elements when Fossil generates its HTML, and such cases require the use of `!important` to override them. <!-- ============================================================ --> # Main UI CSS ## Number of Columns in `/dir` View The width of columns on the [`/dir` page](/dir) is calculated dynamically as the page is generated, to attempt to fit the widest name in a given directory. The number of columns is determined automatically by CSS. To modify the number of columns and/or the entry width: ```css div.columns { columns: WIDTH COLUMN_COUNT !important; /* Examples: columns: 20ex 3 !important columns: auto auto !important */ } /* The default rule uses div.columns, but it can also be selected using: */ div.columns.files { ... } ``` The `!important` qualifier is required here because the style values are dynamically calculated and applied when the HTML is emitted. The file list itself can be further customized via: ```css div.columns > ul { ... } ul.browser { ... } ``` <!-- ============================================================ --> # Forum-specific CSS ## Limiting Display Length of Long Posts Excessively long posts can make scrolling through threads problematic, especially on mobile devices. The amount of a post which is visible can be configured using: ```css div.forumPostBody { max-height: 25em; /* change to the preferred maximum effective height */ overflow: auto; /* tells the browser to add scrollbars as needed */ } ``` |

These can be found in the details.txt file of your skin or under Admin/Skins/Details in the web UI. * ###`timeline-arrowheads` Set this to `0` to hide arrowheads on primary child lines. * ###`timeline-circle-nodes` Set this to `1` to make check-in nodes circular instead of square. * ###`timeline-color-graph-lines` Set this to `1` to colorize primary child lines. * ###`white-foreground` Set this to `1` if your skin uses white (or any light color) text. This tells Fossil to generate darker background colors for branches. ## <a id="adv-style"></a>Advanced Styling If the above options aren't enough for you, it's time to get your hands dirty with CSS. To get started, I recommend first copying all the [graph-related CSS rules](#default-css) to your stylesheet. Then it's simply a matter of making the necessary changes to achieve the look you want. So, next, let's look at the various graph elements and what purpose they serve. Each element used to construct the timeline graph falls into one of two categories: visible elements and positioning elements. We'll start with the latter, less obvious type. ## <a id="pos-elems"></a>Positioning Elements These elements aren't intended to be seen. They're only used to help position the graph and its visible elements. * ###<a id="tl-canvas"></a>`.tl-canvas` Set the left and right margins on this class to give the desired amount of space between the graph and its adjacent columns in the timeline. #### Additional Classes * `.sel`: See [`.tl-node`](#tl-node) for more information. * ###<a id="tl-rail"></a>`.tl-rail` Think of rails as invisible vertical lines on which check-in nodes are placed. The more simultaneous branches in a graph, the more rails required to draw it. Setting the `width` property on this class determines the maximum spacing between rails. This spacing is automatically reduced as the number of rails increases. If you change the `width` of `.tl-node` elements, you'll probably need to change this value, too. * ###<a id="tl-mergeoffset"></a>`.tl-mergeoffset` A merge line often runs vertically right beside a primary child line. This class's `width` property specifies the maximum spacing between the two. Setting this value to `0` will eliminate the vertical merge lines. Instead, the merge arrow will extend directly off the primary child line. As with rail spacing, this is also adjusted automatically as needed. * ###<a id="tl-nodemark"></a>`.tl-nodemark` In the timeline table, the second cell in each check-in row contains an invisible div with this class. These divs are used to determine the vertical position of the nodes. By setting the `margin-top` property, you can adjust this position. ## <a id="vis-elems"></a>Visible Elements These are the elements you can actually see on the timeline graph: the nodes, arrows, and lines. Each of these elements may also have additional classes attached to them, depending on their context. * ###<a id="tl-node"></a>`.tl-node` A node exists for each check-in in the timeline. #### Additional Classes * `.leaf`: Specifies that the check-in is a leaf (i.e. that it has no children in the same branch). * `.merge`: Specifies that the check-in contains a merge. * `.sel`: When the user clicks a node to designate it as the beginning of a diff, this class is added to both the node itself and the [`.tl-canvas`](#tl-canvas) element. The class is removed from both elements when the node is clicked again. * ###<a id="tl-arrow"></a>`.tl-arrow` Arrows point from parent nodes to their children. Technically, this class is just for the arrowhead. The rest of the arrow is composed of [`.tl-line`](#tl-line) elements. There are six additional classes that are used to distinguish the different types of arrows. However, only these combinations are valid: * `.u`: Up arrow that points to a child from its primary parent. * `.u.sm`: Smaller up arrow, used when there is limited space between parent and child nodes. * `.merge.l` or `.merge.r`: Merge arrow pointing either to the left or right. * `.warp`: A timewarped arrow (always points to the right), used when a misconfigured clock makes a check-in appear to have occurred before its parent ([example](https://www.sqlite.org/src/timeline?c=2010-09-29&nd)). * ###<a id="tl-line"></a>`.tl-line` Along with arrows, lines connect parent and child nodes. Line thickness is determined by the `width` property, regardless of whether the line is horizontal or vertical. You can also use borders to create special line styles. Here's a CSS snippet for making dotted merge lines: .tl-line.merge { width: 0; background: transparent; border: 0 dotted #000; } .tl-line.merge.h { border-top-width: 1px; } .tl-line.merge.v { border-left-width: 1px; } #### Additional Classes * `.merge`: A merge line. * `.h` or `.v`: Horizontal or vertical. * `.warp`: A timewarped line. ## <a id="default-css"></a>Default Timeline Graph CSS .tl-canvas { margin: 0 6px 0 10px; } .tl-rail { width: 18px; } .tl-mergeoffset { width: 2px; } .tl-nodemark { margin-top: 5px; } .tl-node { width: 10px; height: 10px; border: 1px solid #000; background: #fff; cursor: pointer; } .tl-node.leaf:after { content: ''; position: absolute; top: 3px; left: 3px; width: 4px; height: 4px; background: #000; } .tl-node.sel:after { content: ''; position: absolute; top: 2px; left: 2px; width: 6px; height: 6px; background: red; } .tl-arrow { width: 0; height: 0; transform: scale(.999); border: 0 solid transparent; } .tl-arrow.u { margin-top: -1px; border-width: 0 3px; border-bottom: 7px solid #000; } .tl-arrow.u.sm { border-bottom: 5px solid #000; } .tl-line { background: #000; width: 2px; } .tl-arrow.merge { height: 1px; border-width: 2px 0; } .tl-arrow.merge.l { border-right: 3px solid #000; } .tl-arrow.merge.r { border-left: 3px solid #000; } .tl-line.merge { width: 1px; } .tl-arrow.warp { margin-left: 1px; border-width: 3px 0; border-left: 7px solid #600000; } .tl-line.warp { background: #600000; } |

The default look and feel works fine in many situations. However, you may want to change the look and feel (the "skin") of Fossil to better suite your own individual tastes. This document provides background information to aid you in that task. ## <a name="builtin"></a>Built-in Skins Fossil comes with multiple built-in skins. If the default skin does not suite your tastes, perhaps one of the other built-in skins will work better. If nothing else, the built-in skins can serve as examples or baselines that you can use to develop your own custom skin. The sources to these built-ins can be found in the Fossil source tree under the skins/ folder. The [skins/](/dir?ci=trunk&name=skins) folder contains a separate subfolder for each built-in skin, with each subfolders holding at least these five files: * css.txt * details.txt * footer.txt * header.txt * js.txt Try out the built-in skins by using the --skin option on the [fossil ui](/help?cmd=ui) or [fossil server](/help?cmd=server) commands. ## <a name="sharing"></a>Sharing Skins The skin of a repository is not part of the versioned state and does not "push" or "pull" like checked-in files. The skin is local to the repository. However, skins can be shared between repositories using the [fossil config](/help?cmd=configuration) command. The "fossil config push skin" command will send the local skin to a remote repository and the "fossil config pull skin" command will import a skin from a remote repository. The "fossil config export skin FILENAME" will export the skin for a repository into a file FILENAME. This file can then be imported into a different repository using the "fossil config import FILENAME" command. Unlike "push" and "pull", the "export" and "import" commands are able to move skins between repositories for different projects. So, for example, if you have a group of related repositories, you can develop a skin for one of them, then get a consistent look across all the repositories by exporting the skin from the first repository and importing into all the others. The file generated by "fossil config export" could be checked into one of your repositories and versioned, if desired. This will not automatically change the skin when looking backwards in time, but it will provide an historical record of what the skin used to be and allow the historical look of the repositories to be recreated if necessary. When cloning a repository, the skin of the new repository is initialized to the skin of the repository from which it was cloned. # Structure Of A Fossil Web Page Every HTML page generated by Fossil has the same basic structure: <blockquote><table border=1 cellpadding=10><tbody> <tr><td style='background-color:lightgreen;text-align:center;'> Fossil-Generated HTML Header</td></tr> <tr><td style='background-color:lightblue;text-align:center;'>Content Header</td></tr> <tr><td style='background-color:lightgreen;text-align:center;'> Fossil-Generated Content</td></tr> <tr><td style='background-color:lightblue;text-align:center;'>Content Footer</td></tr> <tr><td style='background-color:lightgreen;text-align:center;'> Fossil-Generated HTML Footer</td></tr> </tbody></table></blockquote> The green parts are generated by Fossil. The blue parts are things that you, the administrator, get to modify in order to customize the skin. Fossil *usually* (but not always - [see below](#override)) generates the initial HTML Header section of a page. The generated HTML Header will look something like this: <html> <head> <base href="..." /> <meta http-equiv="Content-Security-Policy" content="...." /> <meta name="viewport" content="width=device-width, initial-scale=1.0"> <title>....</title> <link rel="stylesheet" href="..." type="text/css" /> </head> <body> In most cases, it is best to leave the Fossil-generated HTML Header alone. The configurable part of the skin begins with the Content Header section which should followign the following template: <div class="header"> ... top banner and menu bar ... </div> Note that `<div class="header">` and `</div>` tags must be included in the Content Header text of the skin. In other words, you the administrator need to supply that text as part of your skin customization. The Fossil-generated Content section immediately follows the Content Header. The Content section will looks like this: <div class="content"> ... Fossil-generated content here ... </div> After the Content is the custom Content Footer section which should following this template: <div class="footer"> ... skin-specific stuff here ... </div> <script nonce="$nonce"> <th1>styleScript</th1> </script> As with the Content Header, the template elements of the Content Footer should appear exactly as they are shown. Finally, Fossil always adds its own footer (unless overridden) to close out the generated HTML: </body> </html> ## <a name="override"></a>Overriding the HTML Header and Footer Notice that the `<html>`, `<head>`, and opening `<body>` elements at the beginning of the document, and the closing `</body>` and `</html>` elements at the end are automatically generated by Fossil. This is recommended. However, for maximum design flexibility, Fossil allows those elements to be supplied as part of the configurable Content Header and Content Footer. If the Content Header contains the text "`<body`", then Fossil assumes that the Content Header and Content Footer will handle all of the `<html>`, `<head>`, and `<body>` text itself, and the Fossil-generated header and footer will be blank. When overriding the HTML Header in this way, you will probably want to use some of the [TH1 variables documented below](#vars) such as `$stylesheet_url` to avoid hand-writing code that Fossil can generate for you. # Designing, Debugging, and Installing A Custom Skin It is possible to develop a new skin from scratch. But a better and easier approach is to use one of the existing built-in skins as a baseline and make incremental modifications, testing after each step, to obtain the desired result. The skin is controlled by five files: <blockquote><dl> <dt><b>css.txt</b></dt><dd> <p>The css.txt file is the text of the CSS for Fossil. Fossil might add additional CSS elements after the the css.txt file, if it sees that the css.txt omits some CSS components that Fossil needs. But for the most part, the content of the css.txt is the CSS for the page.</dd> <dt><b>details.txt</b><dt><dd> <p>The details.txt file is short list of settings that control the look and feel, mostly of the timeline. The default details.txt file looks like this: <blockquote><pre> timeline-arrowheads: 1 timeline-circle-nodes: 1 timeline-color-graph-lines: 1 white-foreground: 0 </pre></blockquote> The first three setings in details.txt control the appearance of certain aspects of the timeline graph. The number on the right is a boolean - "1" to activate the feature and "0" to disable it. The "white-foreground:" setting should be set to "1" if the page color has light-color text on a darker background, and "0" if the page has dark text on a light-colored background.</dd> <dt><b>footer.txt</b> and <b>header.txt</b></dt><dd> <p>The footer.txt and header.txt files contain the Content Footer and Content Header respectively. Of these, the Content Header is the most important, as it contains the markup used to generate the banner and menu bar for each page. <p>Both the footer.txt and header.txt file are [processed using TH1](#headfoot) prior to being output as part of the overall web page.</dd> <dt><b>js.txt</b></dt><dd> <p>The js.txt file is intended to be javascript. The complete text of this javascript is typically inserted into the Content Footer by this part of the "footer.txt" file: <blockquote><pre> <script nonce="$nonce"> <th1>styleScript</th1> </script> </pre></blockquote> <p>The js.txt file was originally intended to insert javascript that controls the hamburger menu. The footer.txt file probably should contain lines like the above, even if js.txt is empty.</dd> </dl></blockquote> Developing a new skin is simply a matter of creating appropriate versions of these five control files. ### Skin Development Using The Web Interface Users with admin privileges can use the Admin/Skin configuration page on the web interface to develop a new skin. The development of a new skin occurs without disrupting the existing skin. So you can work on a new skin for a Fossil instance while the existing skin is still in active use. The new skin is a "draft" skin. You initialize one of 9 draft skins to either the current skin or to one of the built-in skins. Then use forms to edit the 5 control files described above. The new skin can be tested after each edit. Finally, once the new skin is working as desired, the draft skin is "published" and becomes the new live skin that most users see. ### Skin Development Using A Local Text Editor An alternative approach is to copy the five control files for your baseline skin into a temporary working directory (here called "./newskin") and then launch the [fossil ui](/help?cmd=ui) command with the "--skin ./newskin" option. If the argument to the --skin option contains a "/" character, then the five control files are read out of the directory named. You can then edit the control files in the ./newskin folder using you favorite text editor, and press "Reload" on your browser to see the effects. ## <a name="headfoot"></a>Header and Footer Processing The `header.txt` and `footer.txt` control files of a skin are the HTML text of the Contnet Header and Content Footer, except that before being inserted into the output stream, the text is run through a [TH1 interpreter](./th1.md) that might adjust the text as follows: * All text within <th1>...</th1> is omitted from the output and is instead run as a TH1 script. That TH1 script has the opportunity to insert new text in place of itself, or to inhibit or enable the output of subsequent text. * Text of the form "$NAME" or "$<NAME>" is replaced with the value of the TH1 variable NAME. For example, first few lines of a typical Content Header will look like this: <div class="header"> <div class="title"><h1>$<project_name></h1>$<title>/div> After variables are substituted by TH1, that will look more like this: <div class="header"> <div class="title"><h1>Project Name</h1>Page Title</div> As you can see, two TH1 variable substitutions were done. The same TH1 interpreter is used for both the header and the footer and for all scripts contained within them both. Hence, any global TH1 variables that are set by the header are available to the footer. ## <a name="menu"></a>Customizing the ≡ Hamburger Menu The menu bar of the default skin has an entry to open a drop-down menu with additional navigation links, represented by the ≡ button (hence the name "hamburger menu"). The Javascript logic to open and close the hamburger menu when the button is clicked is contained in the optional Javascript part (js.txt) of the default skin. Out of the box, the drop-down menu shows the [Site Map](../../../sitemap), loaded by an AJAX request prior to the first display. The ≡ button for the hamburger menu is added to the menu bar by the following TH1 command in the default skin header.txt, right before the menu bar links: html "<a id='hbbtn' href='#'>☰</a>" The hamburger button can be repositioned between the other menu links (but the drop-down menu is always left-aligned with the menu bar), or it can be removed by deleting the above statement (the Javascript logic detects this case and remains idle, so it's not necessary to modify the default skin js.txt). The following empty element at the bottom of the default skin header.txt serves as the panel to hold the drop-down menu elements: <div id='hbdrop'></div> Out of the box, the contents of the panel is populated with the [Site Map](../../../sitemap), but only if the panel does not already contain any HTML elements (that is, not just comments, plain text or non-presentational white space). So the hamburger menu can be customized by replacing the empty `<div id='hbdrop'></div>` element with a menu structure knitted according to the following template: <div id="hbdrop" data-anim-ms="400"> <ul class="columns" style="column-width: 20em; column-count: auto"> <!-- NEW GROUP WITH HEADING LINK --> <li> <a href="$home$index_page">Link: Home</a> <ul> <li><a href="$home/timeline">Link: Timeline</a></li> <li><a href="$home/dir?ci=tip">Link: File List</a></li> </ul> </li> <!-- NEW GROUP WITH HEADING TEXT --> <li> Heading Text <ul> <li><a href="$home/doc/trunk/www/customskin.md">Link: Theming</a></li> <li><a href="$home/doc/trunk/www/th1.md">Link: TH1 Scripts</a></li> </ul> </li> <!-- NEXT GROUP GOES HERE --> </ul> </div> The custom `data-anim-ms` attribute can be added to the panel element to direct the Javascript logic to override the default menu animation duration of 400 ms. A faster animation duration of 80-200 ms may be preferred for smaller menus. The animation is disabled by setting the attribute to `"0"`. ## <a name="vars"></a>TH1 Variables Before expanding the TH1 within the header and footer, Fossil first initializes a number of TH1 variables to values that depend on repository settings and the specific page being generated. * **project_name** - The project_name variable is filled with the name of the project as configured under the Admin/Configuration menu. * **project_description** - The project_description variable is filled with the description of the project as configured under the Admin/Configuration menu. * **title** - The title variable holds the title of the page being generated. The title variable is special in that it is deleted after the header script runs and before the footer script. This is necessary to avoid a conflict with a variable by the same name used in my ticket-screen scripts. * **baseurl** - The root of the URL namespace for this server. * **secureurl** - The same as $baseurl except that if the scheme is "http:" it is changed to "https:" * **home** - The $baseurl without the scheme and hostname. For example, if the $baseurl is "http://projectX.com/cgi-bin/fossil" then the $home will be just "/cgi-bin/fossil". * **index_page** - The landing page URI as specified by the Admin/Configuration setup page. * **current_page** - The name of the page currently being processed, without the leading "/" and without query parameters. Examples: "timeline", "doc/trunk/README.txt", "wiki". * **csrf_token** - A token used to prevent cross-site request forgery. * **default_csp** - [Fossil’s default CSP](./defcsp.md) unless [overridden by custom TH1 code](./defcsp.md#th1). Useful within the skin for inserting the CSP into a `<meta>` tag within [a custom `<head>` element](#headfoot). * **nonce** - The value of the cryptographic nonce for the request being processed. * **release_version** - The release version of Fossil. Ex: "1.31" * **manifest_version** - A prefix on the check-in hash of the specific version of fossil that is running. Ex: "\[47bb6432a1\]" * **manifest_date** - The date of the source-code check-in for the version of fossil that is running. * **compiler_name** - The name and version of the compiler used to build the fossil executable. * **login** - This variable only exists if the user has logged in. The value is the username of the user. * **stylesheet_url** - A URL for the internal style-sheet maintained by Fossil. * **log\_image\_url** - A URL for the logo image for this project, as configured on the Admin/Logo page. * **background\_image\_url** - A URL for a background image for this project, as configured on the Admin/Logo page. All of the above are variables in the sense that either the header or the footer is free to change or erase them. But they should probably be treated as constants. New predefined values are likely to be added in future releases of Fossil. ## <a name="procedure"></a>Suggested Skin Customization Procedure Developers are free, of course, to develop new skins using any method they want, but the following is a technique that has worked well in the past and can serve as a starting point for future work: 1. Select a built-in skin that is closest to the desired look. Make copies of the css, footer, and header into files name "css.txt", "details.txt", "footer.txt", and "header.txt" in some temporary directory. If the Fossil source code is available, then these three files can be copied directly out of one of the subdirectories under skins. If sources are not easily at hand, then a copy/paste out of the CSS, footer, and header editing screens under the Admin menu will work just as well. The important point is that the three files be named exactly "css.txt", "footer.txt", and "header.txt" and that they all be in the same directory. 2. Run the [fossil ui](../../../help?cmd=ui) command with an extra option "--skin SKINDIR" where SKINDIR is the name of the directory in which the three txt files were stored in step 1. This will bring up the Fossil website using the tree files in SKINDIR. 3. Edit the four txt files in SKINDIR. After making each small change, press Reload on the web browser to see the effect of that change. Iterate until the desired look is achieved. 4.

The CSP defines a “white list†to tell the browser what types of content (HTML, images, CSS, JavaScript...) the document may reference and the sources the browser is allowed to pull and interpret such content from. The aim is to prevent certain classes of [cross-site scripting][xss] (XSS) and code injection attacks. The browser will not pull content types disallowed by the CSP; the CSP also adds restrictions on the types of inline content the browser is allowed to interpret. Fossil has built-in server-side content filtering logic. For example, it purposely breaks `<script>` tags when it finds them in Markdown and Fossil Wiki documents. (But not in [HTML-formatted embedded docs][hfed]!) We also back that with multiple levels of analysis and checks to find and fix content security problems: compile-time static analysis, run-time dynamic analysis, and manual code inspection. Fossil is open source software, so it benefits from the “[many eyeballs][llaw],†limited by the size of its developer community. However, there is a practical limit to the power of server-side filtering and code quality practices. First, there is an endless battle between those looking for clever paths around such barriers and those erecting the barriers. The developers of Fossil are committed to holding up our end of that fight, but this is, to some extent, a reactive posture. It is cold comfort if Fossil’s developers react quickly to a report of code injection — as we do! — if the bad guys learn of it and start exploiting it first. Second, Fossil has purposefully powerful features that are inherently difficult to police from the server side: HTML tags [in wiki](/wiki_rules) and [in Markdown](/md_rules) docs, [TH1 docs](./th1.md), the Admin → Wiki → “Use HTML as wiki markup language†mode, etc. Fossil’s strong default CSP adds client-side filtering as a backstop for all of this. Fossil site administrators can [modify the default CSP](#override), perhaps to add trusted external sources for auxiliary content. But for maximum safety, site developers are encouraged to work within the restrictions imposed by the default CSP and avoid the temptation to relax the CSP unless they fully understand the security implications of what they are doing. [llaw]: https://en.wikipedia.org/wiki/Linus%27s_Law ## The Default Restrictions The Fossil default CSP declares the following content restrictions: ### <a name="base"></a> default-src 'self' data: This policy means mixed-origin content isn’t allowed, so you can’t refer to resources on other web domains. Browsers will ignore a link like the one in the following Markdown under our default CSP: ![fancy 3D Fossil logotype](https://i.imgur.com/HalpMgt.png) If you look in the browser’s developer console, you should see a CSP error when attempting to render such a page. The default policy does allow inline `data:` URIs, which means you could [data-encode][de] your image content and put it inline within the document: ![small inline image](data:image/gif;base64,R0lGODlh...) That method is best used for fairly small resources. Large `data:` URIs are hard to read and edit. There are secondary problems as well: if you put a large image into a Fossil forum post this way, anyone subscribed to email alerts will get a copy of the raw URI text, which can amount to pages and pages of [ugly Base64-encoded text][b64]. For inline images within [embedded documentation][ed], it suffices to store the referred-to files in the repo and then refer to them using repo-relative URLs: ![large inline image](./inlineimage.jpg) This avoids bloating the doc text with `data:` URI blobs: There are many other cases, [covered below](#serving). [b64]: https://en.wikipedia.org/wiki/Base64 [svr]: ./server/ ### <a name="style"></a> style-src 'self' 'unsafe-inline' This policy allows CSS information to come from separate files hosted under the Fossil repo server’s Internet domain. It also allows inline CSS `<style>` tags within the document text. The `'unsafe-inline'` declaration allows CSS within individual HTML elements: <p style="margin-left: 4em">Indented text.</p> As the "`unsafe-`" prefix on the name implies, the `'unsafe-inline'` feature is suboptimal for security. However, there are a few places in the Fossil-generated HTML that benefit from this flexibility and the work-arounds are verbose and difficult to maintain. Futhermore, the harm that can be done with style injections is far less than the harm possible with injected javascript. And so the `'unsafe-inline'` compromise is accepted for now, though it might go away in some future release of Fossil. ### <a name="script"></a> script-src 'self' 'nonce-%s' This policy disables in-line JavaScript and only allows `<script>` elements if the `<script>` includes a `nonce` attribute that matches the one declared by the CSP. That nonce is a large random number, unique for each HTTP page generated by Fossil, so an attacker cannot guess the value, so the browser will ignore an attacker’s injected JavaScript. That nonce can only come from one of three sources, all of which should be protected at the system administration level on the Fossil server: * **Fossil server C code:** All code paths in Fossil that emit `<script>` elements include the `nonce` attribute. There are several cases, such as the “JavaScript†section of a [custom skin][cs]. That text is currently inserted into each HTML page generated by Fossil,¹ which means it needs to include a `nonce` attribute to allow it to run under this default CSP. We consider JavaScript emitted via these paths to be safe because it’s audited by the Fossil developers. We assume that you got your Fossil server’s code from a trustworthy source and that an attacker cannot replace your Fossil server binary. * **TH1 code:** The Fossil TH1 interpreter pre-defines the [`$nonce` variable](./th1.md#nonce) for use in [custom skins][cs]. For example, some of the stock skins that ship with Fossil include a wall clock feature up in the corner that updates once a minute. These paths are safe in the default Fossil configuration because only the [all-powerful Setup user][su] can write TH1 code that executes in the server’s running context. There is, however, [a default-disabled path](#xss) to beware of, covered in the next section. * **[CGI server extensions][ext]:** Fossil exports the nonce to the CGI in the `FOSSIL_NONCE` environment variable, which it can then use in `<script>` elements it generates. Because these extensions can only be installed by the Fossil server’s system administrator, this path is also considered safe. [ext]: ./serverext.wiki [su]: ./caps/admin-v-setup.md#apsu #### <a name="xss"></a>Cross-Site Scripting via Ordinary User Capabilities We’re so restrictive about how we treat JavaScript because it can lead to difficult-to-avoid scripting attacks. If we used the same CSP for `<script>` tags [as for `<style>` tags](#style), anyone with check-in rights on your repository could add a JavaScript file to your repository and then refer to it from other content added to the site. Since JavaScript code can access any data from any URI served under its same Internet domain, and many Fossil users host multiple Fossil repositories under a single Internet domain, such a CSP would only be safe if all of those repositories are trusted equally. Consider [the Chisel hosting service](http://chiselapp.com/), which offers free Fossil repository hosting to anyone on the Internet, all served under the same `http://chiselapp.com/user/$NAME/$REPO` URL scheme. Any one of those hundreds of repositories could trick you into visiting their repository home page, set to [an HTML-formatted embedded doc page][hfed] via Admin → Configuration → Index Page, with this content: <script src="/doc/trunk/bad.js"></script> That script can then do anything allowed in JavaScript to *any other* Chisel repository your browser can access.The possibilities for mischief are *vast*. For just one example, if you have login cookies on four different Chisel repositories, your attacker could harvest the login cookies for all of them through this path if we allowed Fossil to serve JavaScript files under the same CSP policy as we do for CSS files. This is why the default configuration of Fossil has no way for [embedded docs][ed], [wiki articles][wiki], [tickets][tkt], [forum posts][fp], or [tech notes][tn] to automatically insert a nonce into the page content. This is all user-provided content, which could link to user-provided JavaScript via check-in rights, effectively giving all such users a capability that is usually reserved to the repository’s administrator. The default-disabled [TH1 documents feature][edtf] is the only known path around this restriction. If you are serving a Fossil repository that has any user you do not implicitly trust to a level that you would willingly run any JavaScript code they’ve provided, blind, you **must not** give the `--with-th1-docs` option when configuring Fossil, because that allows substitution of the [pre-defined `$nonce` TH1 variable](./th1.md#nonce) into [HTML-formatted embedded docs][hfed]: <script src="/doc/trunk/bad.js" nonce="$nonce"></script> Even with this feature enabled, you cannot put `<script>` tags into Fossil Wiki or Markdown-formatted content, because our HTML generators for those formats purposely strip or disable such tags in the output. Therefore, if you trust those users with check-in rights to provide JavaScript but not those allowed to file tickets, append to wiki articles, etc., you might justify enabling TH1 docs on your repository, since the only way to create or modify HTML-formatted embedded docs is through check-ins. [ed]: ./embeddeddoc.wiki [edtf]: ./embeddeddoc.wiki#th1 [hfed]: ./embeddeddoc.wiki#html ## <a name="serving"></a>Serving Files Within the Limits There are several ways to serve files within the above restrictions, avoiding the need to [override the default CSP](#override). In decreasing order of simplicity and preference: 1. Within [embedded documentation][ed] (only!) you can refer to files stored in the repo using document-relative file URLs: ![inline image](./inlineimage.jpg) 2. Relative file URLs don’t work from [wiki articles][wiki], [tickets][tkt], [forum posts][fp], or [tech notes][tn], but you can still refer to them inside the repo with [`/doc`][du] or [`/raw`][ru] URLs: ![inline image](/doc/trunk/images/inlineimage.jpg) <img src="/raw/logo.png" style="float: right; margin-left: 2em"> 3. Store the files as [unversioned content][uv], referred to using [`/uv`][uu] URLs instead: ![logo](/uv/logo.png) 4. Use the [optional CGI server extensions feature](./serverext.wiki) to serve such content via `/ext` URLs. 5. Put Fossil behind a [front-end proxy server][svr] as a virtual subdirectory within the site, so that our default CSP’s “self†rules match static file routes on that same site. For instance, your repo might be at `https://example.com/code`, allowing documentes in that repo to refer to: * images as `/image/foo.png` * JavaScript files as `/js/bar.js` * CSS style sheets as `/style/qux.css` Although those files are all outside the Fossil repo at `/code`, keep in mind that it is the browser’s notion of “self†that matters here, not Fossil’s. All resources come from the same Internet domain, so the browser cannot distinguish Fossil-provided content from static content served directly by the proxy server. This method opens up many other potential benefits, such as [TLS encryption](./tls-nginx.md), high-performance tuning via custom HTTP headers, integration with other web technologies like PHP, etc. You might wonder why we rank in-repo content as most preferred above. It is because the first two options are the only ones that cause such resources to be included in an initial clone or in subsequent repo syncs. The methods further down the list have a number of undesirable properties: 1. Relative links to out-of-repo files break in `fossil ui` when run on a clone. 2. Absolute links back to the public repo instance solve that: ![inline image](https://example.com/images/logo.png) ...but using them breaks some types of failover and load-balancing schemes, because it creates a [single point of failure][spof]. 3. Absolute links fail when one’s purpose in using a clone is to recover from the loss of a project web site by standing that clone up [as a server][svr] elsewhere. You probably forgot to copy such external resources in the backup copies, so that when the main repo site disappears, so do those files. Unversioned content is in the middle of the first list above — between fully-external content and fully in-repo content — because it isn’t included in a clone unless you give the `--unversioned` flag. If you then want updates to the unversioned content to be included in syncs, you have to give the same flag to [a `sync` command](/help?cmd=sync). There is no equivalent with other commands such as `up` and `pull`, so you must then remember to give `fossil uv` commands when necessary to pull new unversioned content down. Thus our recommendation that you refer to in-repo resources exclusively.

The following methods are listed in top-down order to give the simplest and most straightforward method first. Further methods dig down deeper into the stack, which is helpful to understand even if you end up using a higher-level method. ### <a name="cspsetting"></a>The `default-csp` Setting If the [`default-csp` setting](/help?cmd=default-csp) is defined and is not an empty string, its value is injected into the page using [TH1](./th1.md) via one or more of the methods below, depending on the skin you’re using and local configuration. Changing this setting is the easiest way to set a nonstandard CSP on your site. Because a blank setting tells Fossil to use its hard-coded default CSP, you have to say something like the following to get a repository without content security policy restrictions: $ fossil set -R /path/to/served/repo.fossil default-csp 'default-src *' We recommend that instead of using the command line to change this setting that you do it via the repository’s web interface, in Admin → Settings. Write your CSP rules in the edit box marked "`default-csp`". Do not add hard newlines in that box: the setting needs to be on a single long line. Beware that changes take effect immediately, so be careful with your edits: you could end up locking yourself out of the repository with certain CSP changes! There are a few reasons why changing this setting via the command line is inadvisable, except for very short settings like the example above: 1. You have to be sure to set it on the repository where you want the CSP to apply. Changing this setting on your local clone doesn’t affect the remote repo you cloned from, which is most likely where you want the CSP restrictions. 2. For more complicated CSPs, the quoting rules for your shell and the CSP syntax may interact, making it difficult or impossible to set your desired CSP via the command line. Setting it via the web UI doesn’t have this problem. ### <a name="th1"></a>TH1 Setup Hook Fossil sets [the TH1 variable `$default_csp`][thvar] from the `default-csp` setting and uses *that* to inject the value into generated HTML pages in its stock configuration. This means that another way you can override this value is to use the [`th1-setup` hook script](./th1-hooks.md), which runs before TH1 processing happens during skin processing: $ fossil set th1-setup "set default_csp {default-src 'self'}" After [the above](#admin-ui), this is the cleanest method. [thvar]: ./customskin.md#vars ### <a name="csrc"></a>Fossil C Source Code When you do neither of the above things, Fossil uses [a hard-coded default](/info?ln=527-530&name=65a555d0d4fb846b). We tell you about this not to suggest that you hack the Fossil C source code to change the CSP but simply to document the next step before we move down-stack. ### <a name="header"></a>Skin Header [In the normal case](./customskin.md#override), Fossil injects the CSP retrieved by one of the above methods into the header of all HTML documents it generates: ```HTML <head>... <meta http-equiv="Content-Security-Policy" content="..."> ... ``` Fossil skips this when you’re using a custom skin *and* its [Header section](./customskin.md#headfoot) includes a `<body>` tag. This is because prior to Fossil 2.5, the Header for a custom skin normally contained everything from the opening `<html>` tag through the leading `<body>` tag. From that version onward, Fossil now generates that header when possible, so that the skin’s Header normally provides only the opening tags of the document body, rather than the HTML header. When we added CSP support in Fossil 2.7, we made use of that mechanism to inject the CSP into the generated HTML document header. For backwards compatibility, Fossil skips this when the skin’s Header includes a `<body>` tag. Fossil takes that as a hint that it’s dealing with a skin made in the pre-Fossil-2.5 days and doesn’t try to blindly override it. The problem then is that you may be a Fossil user from the days before Fossil 2.5, and you may be using a custom skin. This includes users who selected one of the stock skins, since for the purposes of this section, there is no difference between the cases. If you go into Admin → Skins → Header and find a `<body>` tag, none of the above will apply to your repo since Fossil will not be injecting its CSP into your pages. If you selected one of the stock skins (e.g. Khaki) prior to upgrading to Fossil 2.5+ and didn’t make any changes to it since that time, you can take the simplest option, which is to simply revert to the stock version of the skin, so your pages will have the CSP injected, at which point this document will begin describing what Fossil does with that repo. If you’re using a customized version of one of the stock skins, the skinning mechanism has a diff feature to make it easier to fold your local changes into the stock version. If you’re using a fully customized skin, we recommend replicating the method that [the Bootstrap skin uses][dcinj].² Alone among the stock Fossil skins, Bootstrap still does old-style Header processing, providing the entire HTML header and the start of the document body. We do *not* recommend injecting an explicit `Content-Security-Policy` meta tag into a header to override Fossil’s default CSP. That means you have to edit the skin every time you want to change the CSP. Use the TH1 `$default_csp` variable like the Bootstrap skin does so you can use one of the methods above with your custom skin, so the CSP can vary independently of the skin. [dcinj]: /info?ln=7&name=bef080a6929a3e6f ### <a name="fep"></a>Front-End Proxy If your Fossil repo is behind some sort of HTTP [front-end proxy][svr], the [preferred method][pmcsp] for setting the CSP is via a custom HTTP header, which most HTTP reverse proxy programs allow. Beware that if you have a CSP set via both the HTTP and HTML headers that the two CSPs [merge](https://stackoverflow.com/a/51153816/142454), taking the most restrictive elements of each CSP. If you wish the proxy layer’s setting to completely override Fossil’s setting, you will need to combine that with one of the methods above to either remove the Fossil-provided CSP or to make Fossil provide a no-restrictions CSP which the front-end proxy can then tighten down. [pmcsp]: https://developers.google.com/web/fundamentals/security/csp/#the_meta_tag ------------ **Asides and Digressions:** 1. Fossil might someday switch to serving the “JavaScript†section of a custom skin as a virtual text file, allowing it to be cached by the browser, reducing page load times. 2. The stock Bootstrap skin *did* provide redundant CSP text from Fossil 2.7 through Fossil 2.9, so setting the CSP via the higher level methods did not work with that skin. We fixed this in Fossil 2.10, but if you selected the Bootstrap skin prior to that, you’re now running on a *copy* of it stored in your repo settings table, so the change to the stock version of the skin won’t affect that repo automatically. You will have to either merge the diffs in with your local changes or revert to the stock version of the skin.

Instead of storing or transmitting the complete content of an artifact, Fossil stores or transmits only the changes relative to a related artifact. </p> <p>This document describes the delta-encoding format used by Fossil. The intended audience is developers working on either <a href="index.wiki">Fossil</a> itself, or on tools compatible with Fossil. Understanding of this document is <em>not</em> required for ordinary users of Fossil. This document is an implementation detail.</p> <p>This document only describes the delta file format. A [./delta_encoder_algorithm.wiki|separate document] describes one possible algorithm for generating deltas in this format.</p> <h2>1.1 Sample Software And Analysis Tools</h2> <p>The core routines used to generate and apply deltas in this format are contained in the [../src/delta.c|delta.c] source file. Interface logic, including "test-*" commands to directly manipulate deltas are contained in the [../src/deltacmd.c|deltacmd.c] source file. SQL functions to create, apply, and analyze deltas are implemented by code in the [../src/deltafunc.c|deltafunc.c] source file. <p>The following command-line tools are available to create and apply deltas and to test the delta logic: * [/help?cmd=test-delta|fossil test-delta] → Run self-tests of the delta logic * [/help?cmd=test-delta-create|fossil test-delta-create X Y] → compute a delta that converts file X into file Y. Output that delta. * [/help?cmd=test-delta-apply|fossil test-delta-apply X D] → apply delta D to input file X and output the result. * [/help?cmd=test-delta-analyze|fossil test-delta-analyze X Y] → compute and delta that converts file X into file Y but instead of writing the delta to output, write performance information about the delta. <p>When running the [/help?cmd=sqlite3|fossil sql] command to get an interactive SQL session connected to the repository, the following additional SQL functions are provided: * <b>delta_create(</b><i>X</i><b>,</b><i>Y</i><b>)</b> → Compute a data that carries blob X into blob Y and return that delta as a blob. * <b>delta_apply(</b><i>X</i><b>,</b><i>D</i><b>)</b> → Apply delta D to input blob X return a new blob which is the result. * <b>delta_output_size(</b><i>D</i>)</b> → Return the size of the output that would result from applying delta D. * <b>delta_parse(</b><i>D</i>)</b> → This is a table-valued function that returns one row for the header, for the trailer, and for each segment in delta D. <a name="structure"></a><h1>2.0 Structure</h1> <img src="delta1.gif" align="left" hspace="10"> <p>A delta consists of three parts, a "header", a "trailer", and a "segment-list" between them.</p> <p>Both header and trailer provide information about the target helping the decoder, and the segment-list describes how the target can be constructed from the original.</p> <a name="header"></a><h2>2.1 Header</h2> <img src="delta6.gif" align="left" hspace="10"> <p>The header consists of a single number followed by a newline character (ASCII 0x0a). The number is the length of the target in bytes.</p> <p>This means that, given a delta, the decoder can compute the size of the target (and allocate any necessary memory based on that) by simply reading the first line of the delta and decoding the number found there. In other words, before it has to decode everything else.</p> <a name="trailer"></a><h2>2.2 Trailer</h2> <img src="delta5.gif" align="left" hspace="10"> <p>The trailer consists of a single number followed by a semicolon (ASCII 0x3b). This number is a checksum of the target and can be used by a decoder to verify that the delta applied correctly, reconstructing the target from the original.</p> <p>The checksum is computed by treating the target as a series of 32-bit integer numbers (MSB first), and summing these up, modulo 2^32-1. A target whose length is not a multiple of 4 is padded with 0-bytes (ASCII 0x00) at the end.</p> <p>By putting this information at the end of the delta a decoder has it available immediately after the target has been reconstructed fully.</p> <a name="slist"></a><h2>2.3 Segment-List</h2> <img src="delta2.gif" align="left" hspace="10"> <p>The segment-list of a delta describes how to create the target from the original by a combination of inserting literal byte-sequences and copying ranges of bytes from the original. This is where the compression takes place, by encoding the large common parts of original and target in small copy instructions.</p> <p>The target is constructed from beginning to end, with the data generated by each instruction appended after the data of all previous instructions, with no gaps.</p> <a name="insertlit"></a><h3>2.3.1 Insert Literal</h3> <p>A literal is specified by two elements, the size of the literal in bytes, and the bytes of the literal itself.</p> <img src="delta4.gif" align="left" hspace="10"> <p>The length is written first, followed by a colon character (ASCII 0x3a), followed by the bytes of the literal.</p> <a name="copyrange"></a><h3>2.3.2 Copy Range</h3> <p>A range to copy is specified by two numbers, the offset of the first byte in the original to copy, and the size of the range, in bytes. The size zero is special, its usage indicates that the range extends to the end of the original.</p> <img src="delta3.gif" align="left" hspace="10"> <p>The length is written first, followed by an "at" character (ASCII 0x40), then the offset, followed by a comma (ASCII 0x2c).</p> <a name="intcoding"></a><h1>3.0 Encoding of integers</h1> <p> The format currently handles only 32 bit integer numbers.

Only people with check-in privileges can modify the documentation. (This might be either an advantage or disadvantage, depending on the nature of your project.) We will call documentation that is included as files in the source tree "embedded documentation". <h1>1.0 Fossil Support For Embedded Documentation</h1> The fossil web interface supports embedded documentation using the "/doc" page. To access embedded documentation, one points a web browser to a fossil URL of the following form: <blockquote> <i><baseurl></i><big><b>/doc/</b></big><i><version></i><big><b>/</b></big><i><filename></i> </blockquote> The <i><baseurl></i> is the main URL used to access the fossil web server. For example, the <i><baseurl></i> for the fossil project itself is [https://www.fossil-scm.org/fossil]. If you launch the web server using the "[/help?cmd=ui|fossil ui]" command line, then the <i><baseurl></i> is usually <b>http://localhost:8080/</b>. The <i><version></i> is the [./checkin_names.wiki|name of a check-in] that contains the embedded document. This might be a hash prefix for the check-in, or it might be the name of a branch or tag, or it might be a timestamp. See the prior link for more possibilities and examples. <a id="ckout"></a>The <i><version></i> can also be the special identifier "<b>ckout</b>". The "<b>ckout</b>" keywords means to pull the documentation file from the local source tree on disk, not from the any check-in. The "<b>ckout</b>" keyword only works when you start your server using the "[/help?cmd=server|fossil server]" or "[/help?cmd=ui|fossil ui]" commands. The "/doc/ckout" URL is intended to show a preview of the documentation you are currently editing but have not yet you checked in. The original designed purpose of the "ckout" feature is to allow the user to preview local changes to documentation before committing the change. This is an important facility, since unlike other document languages like HTML, there is still a lot of variation among rendering engines for Fossil's markup languages, Markdown and Fossil Wiki. Your changes may look fine in your whizzy GUI Markdown editor, but what actually matters is how <i>Fossil</i> will interpret your Markdown text. Therefore, you should always preview your edits before committing them. Finally, the <i><filename></i> element of the URL is the pathname of the documentation file relative to the root of the source tree. The mimetype (and thus the rendering) of documentation files is determined by the file suffix. Fossil currently understands [/mimetype_list|many different file suffixes], including all the popular ones such as ".css", ".gif", ".htm", ".html", ".jpg", ".jpeg", ".png", and ".txt". Documentation files whose names end in ".wiki" use the [/wiki_rules | fossil wiki markup] - a safe subset of HTML together with some wiki rules for paragraph breaks, lists, and hyperlinks. Documentation files ending in ".md" or ".markdown" use the [/md_rules | Markdown markup language]. Documentation files ending in ".txt" are plain text. Wiki, markdown, and plain text documentation files are rendered with the standard fossil header and footer added. Most other mimetypes are delivered directly to the requesting web browser without interpretation, additions, or changes. <h2>1.1 HTML Rendering With Fossil Headers And Footers</h2> <a name="html"></a>Files with the mimetype "text/html" (the .html or .htm suffix) are usually rendered directly to the browser without interpretation. However, if the file begins with a <div> element like this: <b><div class='fossil-doc' data-title='<i>Title Text</i>'></b> Then the standard Fossil header and footer are added to the document prior to being displayed. The "class='fossil-doc'" attribute is required for this to occur. The "data-title='...'" attribute is optional, but if it is present the text will become the title displayed in the Fossil header. An example of this can be seen in Fossil Documentation Index www/permutedindex.html: * [/file/www/permutedindex.html?txt|source text for <b>www/permutedindex.html</b>] * [/doc/trunk/www/permutedindex.html|<b>www/permutedindex.html</b> rendered as HTML] Beware that such HTML files render in the same browser security context as all other embedded documentation served from Fossil; they are not fully-independent web pages. One practical consequence of this is that embedded <tt><script></tt> tags will cause a [https://developer.mozilla.org/en-US/docs/Web/HTTP/CSP | Content Security Policy] error in your browser with the default CSP as served by Fossil. See the documentation on [./customskin.md#headfoot | Header and Footer Processing] and [./defcsp.md | The Default CSP]. <h1>2.0 Server-Side Text Substitution</h1> Fossil can do a few types of substitution of server-side information into the embedded document. <h2>2.1 "$ROOT" In HTML and Markdown Hyperlinks</h2> Hyperlinks in Markdown and HTML embedded documents can reference the root of the Fossil repository using the special text "$ROOT" at the beginning of a URL. For example, a Markdown hyperlink to the Markdown formatting rules might be written in the embedded document like this: <nowiki><pre> [Markdown formatting rules]($ROOT/wiki_rules) </pre></nowiki> Depending on how the how the Fossil server is configured, that hyperlink might be renderer like one of the following: <nowiki><pre> <a href="/wiki_rules">Wiki formatting rules</a> <a href="/cgi-bin/fossil/wiki_rules">Wiki formatting rules</a> </pre></nowiki> So, in other words, the "$ROOT" text is converted into whatever the "<baseurl>" is for the document. This substitution works for HTML and Markdown documents. It does not work for Wiki embedded documents, since with Wiki you can just begin a URL with "/" and it automatically knows to prepend the $ROOT. <h2>2.2 "$CURRENT" In "/doc/" Hyperlinks</h2> Similarly, URLs of the form "/doc/$CURRENT/..." have the check-in hash of the check-in currently being viewed substituted in place of the "$CURRENT" text. This feature, in combination with the "$ROOT" substitution above, allows an absolute path to be used for hyperlinks. For example, if an embedded document documented wanted to reference some other document in a separate file named "www/otherdoc.md", it could use a URL like this: <nowiki><pre> [Other Document]($ROOT/doc/$CURRENT/www/otherdoc.md) </pre></nowiki> As with "$ROOT", this substitution only works for Markdown and HTML documents. For Wiki documents, you would need to use a relative URL. <h2 id="th1">2.3 TH1 Documents</h2> Fossil will substitute the value of [./th1.md | TH1 expressions] within <tt>{</tt> curly braces <tt>}</tt> into the output HTML if you have configured it with the <tt>--with-th1-docs</tt> option, which is disabled by default. Since TH1 is a full scripting language, this feature essential grants the ability to execute code on the server to any with check-in privilege for the project. This is a security risk that needs to be carefully managed. The feature is off by default. Administrators should understand and carefully assess the risks before enabling the use of TH1 within embedded documentation. <h1>3.0 Examples</h1> This file that you are currently reading is an example of embedded documentation. The name of this file in the fossil source tree is "<b>www/embeddeddoc.wiki</b>". You are perhaps looking at this file using the URL: [http://www.fossil-scm.org/fossil/doc/trunk/www/embeddeddoc.wiki]. The first part of this path, the "[http://www.fossil-scm.org/fossil]", is the base URL. You might have originally typed: [http://www.fossil-scm.org/]. The web server at the www.fossil-scm.org site automatically redirects such links by appending "fossil". The "fossil" file on www.fossil-scm.org is really a CGI script which runs the fossil web service in CGI mode. The "fossil" CGI script looks like this: <blockquote><pre> #!/usr/bin/fossil repository: /fossil/fossil.fossil </pre></blockquote> This is one of the many ways to set up a <a href="./server/">Fossil server</a>. The "<b>/trunk/</b>" part of the URL tells fossil to use the documentation files from the most recent trunk check-in. If you wanted to see an historical version of this document, you could substitute the name of a check-in for "<b>/trunk/</b>". For example, to see the version of this document associated with check-in [9be1b00392], simply replace the "<b>/trunk/</b>" with "<b>/9be1b00392/</b>". You can also substitute the symbolic name for a particular version or branch. For example, you might replace "<b>/trunk/</b>" with "<b>/experimental/</b>" to get the latest version of this document in the "experimental" branch. The symbolic name can also be a date and time string in any of the following formats:</p> <ul> <li> <i>YYYY-MM-DD</i> <li> <i>YYYY-MM-DD</i><b>T</b><i>HH:MM</i> <li> <i>YYYY-MM-DD</i><b>T</b><i>HH:MM:SS</i> </ul> When the symbolic name is a date and time, fossil shows the version of the document that was most recently checked in as of the date and time specified. So, for example, to see what the fossil website looked like at the beginning of 2010, enter: <blockquote> <a href="http://www.fossil-scm.org/fossil/doc/2010-01-01/www/index.wiki"> http://www.fossil-scm.org/fossil/doc/<b>2010-01-01</b>/www/index.wiki </a> </blockquote> The file that encodes this document is stored in the fossil source tree under the name "<b>www/embeddeddoc.wiki</b>" and so that name forms the last part of the URL for this document. As I sit writing this documentation file, I am testing my work by running the "<b>fossil ui</b>" command line and viewing <b>http://localhost:8080/doc/ckout/www/embeddeddoc.wiki</b> in Firefox. I am doing this even though I have not yet checked in the "<b>www/embeddeddoc.wiki</b>" file for the first time. Using the special "<b>ckout</b>" version identifier on the "<b>/doc</b>" page it is easy to make multiple changes to multiple files and see how they all look together before committing anything to the repository. |

This technical note explains the process. </blockquote> <h2>Building An Encryption-Enabled Fossil</h2><blockquote> The SQLite Encryption Extension (SEE) is proprietary software and requires [http://www.hwaci.com/cgi-bin/see-step1|purchasing a license]. <p> Assuming you have an SEE license, the first step of compiling Fossil to use SEE is to create an SEE-enabled version of the SQLite database source code. This alternative SQLite database source file should be called "sqlite3-see.c" and should be placed in the src/ subfolder of the Fossil sources, right beside the public-domain "sqlite3.c" source file. Also make a copy of the SEE-enabled "shell.c" file, renamed as "shell-see.c", and place it in the src/ subfolder beside the original "shell.c". <p> Add the --with-see command-line option to the configuration script to enable the use of SEE on unix-like systems. <blockquote><pre> ./configure --with-see; make </pre></blockquote> <p>To build for Windows using MSVC, add the "USE_SEE=1" argument to the "nmake" command line. <blockquote><pre> nmake -f makefile.msc USE_SEE=1 </pre></blockquote> </blockquote> <h2>Using Encrypted Repositories</h2><blockquote> Any Fossil repositories whose filename ends with ".efossil" is taken to be an encrypted repository. Fossil will prompt for the encryption password and attempt to open the repository database using that password. <p> Every invocation of fossil on an encrypted repository requires retyping the encryption password. To avoid excess password typing, consider using the "fossil shell" command which prompts for the password just once, then reuses it for each subsequent Fossil command entered at the prompt. <p> On Windows, the "fossil server", "fossil ui", and "fossil shell" commands do not (currently) work on an encrypted repository. </blockquote> <h2>Additional Security</h2><blockquote> Use the FOSSIL_SECURITY_LEVEL environment for additional protection. <blockquote><pre> export FOSSIL_SECURITY_LEVEL=1 </pre></blockquote> A setting of 1 or greater prevents fossil from trying to remember the previous sync password. <blockquote><pre> export FOSSIL_SECURITY_LEVEL=2 </pre></blockquote> A setting of 2 or greater causes all password prompts to be preceded by a random translation matrix similar to the following: <blockquote><pre> abcde fghij klmno pqrst uvwyz qresw gjymu dpcoa fhkzv inlbt </pre></blockquote> When entering the password, the user must substitute the letter on the second line that corresponds to the letter on the first line. Uppercase substitutes for uppercase inputs, and lowercase substitutes for lowercase inputs. Letters that are not in the translation matrix (digits, punctuation, and "x") are not modified. For example, given the translation matrix above, if the password is "pilot-9crazy-xube", then the user must type "fmpav-9ekqtb-xirw". This simple substitution cypher helps prevent password capture by keyloggers. </blockquote> |

Most of these seem to be primarily documented in the source code, with the primary exception of `--args` which is described in the usage text printed by running fossil with no arguments at all. Global Options -------------- The following options are understood by the fossil command itself, and are collected before any subcommand begins processing. `--args FILENAME`: Read the file `FILENAME` and replace these two arguments with its content. Each line of the file is assumed to be an argument unless it starts with '-' and contains a space, in which case it is assumed to be another flag and is treated as such. `--args FILENAME` may be used in conjunction with any other flags. `--case-sensitive BOOL`: Override the `case-sensitive` setting, which can override the native preferences of the platform for case sensitive file names: insensitive on Windows, sensitive on Unix. There are probably odd interactions possible if you mix case sensitive and case insensitive file systems on any single platform. This option or the global setting should be used to force the case sensitivity to the most sensible condition. `--chdir DIRECTORY`: Change to the named directory before processing any commands. `--comfmtflags NUMBER`: Specify flags that control how check-in comments and certain other text outputs are formatted for display. The flags are individual bits in `NUMBER`, which must be specified in base 10: * _0_ — Uses the revised algorithm with no special handling. * _1_ — Uses the legacy algorithm, other flags are ignored. * _2_ — Trims leading and trailing carriage-returns and line-feeds where they do not materially impact pre-existing formatting (i.e. at the start of the comment string _and_ right before line indentation). * _4_ — Trims leading and trailing spaces where they do not materially impact the pre-existing formatting (i.e. at the start of the comment string _and_ right before line indentation). * _8_ — Attempts to break lines on word boundaries while honoring the logical line length. * _16_ — Looks for the original comment text within the text being printed. Upon matching, a new line will be emitted, thus preserving more of the pre-existing formatting. `--comment-format NUMBER`: Alias for `--comfmtflags NUMBER`. `--errorlog ERRLOG`: Name a file to which fossil will log panics, errors, and warnings. `--help`: If `--help` is found anywhere on the command line, translate the command to `fossil help cmdname` where `cmdname` is the first argument that does not begin with a `-` character. If all arguments start with `-`, translate to `fossil help argv[1] argv[2]...`. `--httptrace`: (Sets `g.fHttpTrace`.) Trace outbound HTTP requests. `--localtime`: Override the `timeline-utc` option to explicitly use local time. `--nocgi`: Prevent fossil from acting as a CGI by default even if the `GATEWAY_INTERFACE` environment variable is set. `--no-th-hook`: (Sets `g.fNoThHook`.) Override the `th1-hooks` setting and prevent any TH1 hooks from being executed. `--quiet`: (Sets `g.fQuiet`.) Cause fossil to suppress various messages and progress indicators that would otherwise be printed. `--sqltrace`: (Sets `g.SqlTrace`.) Implies `--sqlstats`. Trace certain SQLite database activity, especially showing every SQL query processed. `--sqlstats`: (Sets `g.fSqlStats`.) Print a number of performance statistics about each SQLite database used when it is closed. `--sshtrace`: (Sets `g.fSshTrace`.) `--ssl-identity`: The fully qualified name of the file containing the client certificate and private key to use, in PEM format. It can be created by concatenating the client certificate and private key files. This identity will be presented to SSL servers to authenticate the client, in addition to the normal password authentication. `--systemtrace`: (Sets `g.fSystemTrace`.) Trace all commands launched as sub processes. `--user LOGIN`: (Sets `g.zLogin`) Also `-U LOGIN`. Set the user name used with the repository. `--utc`: Override the `timeline-utc` option to explicitly use UTC time. `--vfs VFSNAME`: Load the named VFS into SQLite. Environment Variables --------------------- The location of the user's account-wide [configuration database][configdb] depends on the operating system and on the existance of various environment variables and/or files. See the discussion of the [configuration database location algorithm][configloc] for details. `EDITOR`: Name the editor to use for check-in and stash comments. Overridden by the local or global `editor` setting or the `VISUAL` environment variable. `FOSSIL_BREAK`: If set, an opportunity will be created to attach a debugger to the Fossil process prior to any significant work being performed. `FOSSIL_FORCE_TICKET_MODERATION`: If set, *ALL* changes for tickets will be required to go through moderation (even those performed by the local interactive user via the command line). This can be useful for local (or remote) testing of the moderation subsystem and its impact on the contents and status of tickets. `FOSSIL_FORCE_WIKI_MODERATION`: If set, *ALL* changes for wiki pages will be required to go through moderation (even those performed by the local interactive user via the command line). This can be useful for local (or remote) testing of the moderation subsystem and its impact on the contents and status of wiki pages. `FOSSIL_HOME`: Location of [configuration database][configdb]. See the [configuration database location][configloc] description for additional information. `FOSSIL_USE_SEE_TEXTKEY`: If set, treat the encryption key string for SEE as text to be hashed into the actual encryption key. This has no effect if Fossil was not compiled with SEE support enabled. `FOSSIL_USER`: Name of the default user account if the checkout, local or global `default-user` setting is not present. The first environment variable found in the environment from the list `FOSSIL_USER`, `USER`, `LOGNAME`, and `USERNAME` is the user name. If none of those are set, then the default user name is "root". See the discussion of Fossil Username below for a lot more detail. `FOSSIL_SECURITY_LEVEL`: If set to any of the values listed below, additional measures for password security will be enabled (also see [How To Use Encrypted Repositories][encryptedrepos.wiki]): [encryptedrepos.wiki]: /doc/trunk/www/encryptedrepos.wiki * _≥1_ — Do not remember passwords. * _≥2_ — Use a scrambled matrix for password input. `FOSSIL_TCL_PATH`: When Tcl stubs support is configured, point to a specific file or folder containing the version of Tcl to load at run time. `FOSSIL_TEST_DANGEROUS_IGNORE_OPEN_CHECKOUT`: When set to the literal value `YES_DO_IT`, the test suite will relax the constraint that some tests may not run within an open checkout. This is subject to removal in the future. `FOSSIL_VFS`: Name a VFS to load into SQLite. `GATEWAY_INTERFACE`: If present and the `--nocgi` option is not, assume fossil is invoked from a web server as a CGI command, and act accordingly. `HOME`: Potential location of the [configuration database][configdb]. See the [configuration database location][configloc] description for details. `HOMEDRIVE`, `HOMEPATH`: (Windows) Location of the `~/.fossil` file. The first environment variable found in the environment from the list `FOSSIL_HOME`, `LOCALAPPDATA` (Windows), `APPDATA` (Windows), `HOMEDRIVE` and `HOMEPATH` (Windows, used together), and `HOME` is used as the location of the `~/.fossil` file. `HTTP_HOST`: If defined, included in error log messages. `http_proxy`: If the global or local settings `proxy` is not set, this is used as the default value for the `proxy` setting. `HTTP_USER_AGENT`: If defined, included in error log messages. `LOCALAPPDATA`: (Windows) Location of the `~/.fossil` file. The first environment variable found in the environment from the list `FOSSIL_HOME`, `LOCALAPPDATA` (Windows), `APPDATA` (Windows), `HOMEDRIVE` and `HOMEPATH` (Windows, used together), and `HOME` is used as the location of the `~/.fossil` file. `LOGNAME`: Name of the logged in user on many Unix-like platforms. Used as the fossil user name if `FOSSIL_USER` is not specified. See the discussion of Fossil Username below for a lot more detail. `PATH`: Used by most platforms to locate programs invoked without a fully qualified name. Explicitly used by `fossil ui` on certain platforms to choose the browser to launch. `PATH_INFO`: If defined, included in error log messages. `QUERY_STRING`: If defined, included in error log messages. `REMOTE_ADDR`: If defined, included in error log messages. `REMOTE_HOST`: Used by `fossil http` run from `stunnel` to identify the remote host. `REQUEST_METHOD`: If defined, included in error log messages. `REQUEST_URI`: If defined, included in error log messages. `SCRIPT_NAME`: If defined, included in error log messages. `SSH_CONNECTION`: Informs CGI processing if the remote client is SSH. `SQLITE_FORCE_PROXY_LOCKING`: From `sqlite3.c`, 1 means force always use proxy, 0 means never use proxy, and undefined means use proxy for non-local files only. `SQLITE_TMPDIR`: Names the temporary file location for SQLite. When set, this will be used instead of `TMPDIR`. `SYSTEMROOT`: (Windows) Used to locate `notepad.exe` as a fall back comment editor. `TERM`: If the linenoise library is used (almost certainly not on Windows), it will check `TERM` to verify that the interactive terminal is not named on a short list on terminals known to not work with linenoise. Linenoise is a library that provides command history and command line editing to interactive programs, and can be used in the `fossil sqlite3` command. `TH1_DELETE_INTERP`: Set this variable to ask fossil to explicitly delete the TH1 interpreter, if it is loaded, then check that it released all of its allocated memory, when exiting fossil. This is not strictly necessary, but makes debugging memory leaks easier. See [main.c near line 386](/artifact/e75796be5338a81c?ln=386,391) for the code. `TH1_ENABLE_DOCS`: Override the local or global setting `tcl-docs` to enable TH1 documents in fossil. `TH1_ENABLE_HOOKS`: Override the local or global setting `tcl-hooks` to enable TH1 hooks in fossil. `TH1_ENABLE_TCL`: Override the local or global setting `tcl` to enable Tcl in fossil. `TH1_TEST_ANON_CAPS`: Override the default anonymous permissions used when processing the `--set-anon-caps` option for the `test-th-eval`, `test-th-render`, and `test-th-source` test commands. `TH1_TEST_USER_CAPS`: Override the default user permissions used when processing the `--set-user-caps` option for the `test-th-eval`, `test-th-render`, and `test-th-source` test commands. `TMPDIR`: Names the temporary file location for SQLite. `USER`: Name of the logged in user on many Unix-like platforms. Used as the fossil user name if `FOSSIL_USER` is not specified. See the discussion of Fossil Username below for a lot more detail. `USERNAME`: Name of the logged in user on Windows platforms. Used as the fossil user name if `FOSSIL_USER` is not specified. See the discussion of Fossil Username below for a lot more detail. `VISUAL`: Name the editor to use for check-in and stash comments. Overrides the `EDITOR` environment variable. Overridden by the local or global `editor` setting. Notes on Related Values ----------------------- ### CGI and JSON Parameters The JSON API implementation looks up many values in the first of several places searched. This unifies the parameter handling logic, allows the caller to choose whether to prefer URL parameters, request headers, or the POST payload, and allows the `fossil json` command to share most of the same logic as the `/json` API path. The search order is a POST payload, GET/COOKIE/non-JSON POST, JSON POST, the system environment. See the comment above the implementation of [`json_getenv`][json.c] for some further discussion. [json.c]: /artifact/6df1d80dece8968b?ln=277,290 ### Comment Editor The editor used to edit a check-in or stash comment is named by the local or global setting `editor`. If neither is set, then the environment variables `VISUAL`, and `EDITOR` are checked in that order. On Windows, if no editor is named, then Notepad is used. Note that the operation will be aborted if `notepad.exe` is not found in the Windows folder. On Unix-like platforms, if no editor is named, then a message is displayed on stdout, and stdin is read until a single line containing only a dot is seen. ### Error logging If logging errors to a file, fossil will include the values of the following environment variables in the error log entry if they are defined: `HTTP_HOST`, `HTTP_USER_AGENT`, `PATH_INFO`, `QUERY_STRING`, `REMOTE_ADDR`, `REQUEST_METHOD`, `REQUEST_URI`, and `SCRIPT_NAME`. ### Fossil Username In absence of any explicit setting, fossil will use the same name you logged in to your platform with, as the user name when interacting with local and remote repositories. Note that only the name is shared, fossil makes no attempt to share or leverage any platform's authentication mechanisms or passwords. When logging in to a repository, it tries a series of sources for the user name, and the first non-blank name that succeeds is the logged in user. The order is: 1. The --user and -U command-line options. 2. If running within an open checkout (the local database is open), check in its table of values stored per open checkout for the value stored by `fossil user default USERNAME`. 3. The default user in the repository (setting `default-user`) 4. The `FOSSIL_USER` environment variable. 5. The `USER` environment variable. 6. The `LOGNAME` environment variable. 7. The `USERNAME` environment variable. 8. Check if the user can be extracted from the remote URL, if there is a remote URL. Items 2 and 3 are both set by `fossil user default USERNAME`, the first within an open checkout, the second outside and using the `-R REPOSITORY` option to identify the repository. Both cases require that the named user be present in the repository when the default user is assigned. Although the default user is internally stored as if it were a setting named `default-user`, it is not accessible through the `fossil set` command. Items 5, 6, and 7 cover most of the names of an environment variable set automatically by the platform with the name of the platform's logged in user for use by programs. Historically, `USER` comes from Unix System-V, `LOGNAME` from BSD, and `USERNAME` from Windows, but many Linux distributions will set both `USER` and `LOGNAME` for broad compatibility. When creating a new repository, fossil needs a user name for the admin user granted the "s" permission. But since fossil generally expects that `fossil new` or `fossil clone` are used outside of any checkout (especially when run for the first time without any checkouts at all or the users's global settings database), it looks in a shorter list of places for a non-blank name. In the special case of a clone, `default-user` can be copied from the original, and so it can be set in the clone even before any users have been created, and in that case it will be the new admin user. If `default-user` is not set, then the first found environment variable from the list `FOSSIL_USER`, `USER`, `LOGNAME`, and `USERNAME`, is the user name. As a final fallback, if none of those are set, then the default user name is "root". ### Configuration Database Location Fossil keeps some information pertinent to each user in the user's [configuration database file][configdb]. The configuration database file includes the global settings and the list of repositories and checkouts used by `fossil all`. The location of the configuration database file depends on the operating system and on the existance of various environment variables and/or files. In brief, the configuration database is usually: * Traditional unix → "`$HOME/.fossil`" * Windows → "`%LOCALAPPDATA%/_fossil`" * [XDG-unix][xdg] → "`$HOME/.config/fossil.db`" [xdg]: https://www.freedesktop.org/wiki/ See the [configuration database location algorithm][configloc] discussion for full information. ### SQLite VFS to use See [the SQLite documentation](http://www.sqlite.org/vfs.html) for an explanation of what a VFS actually is and what it does. If the default VFS underneath SQLite is not suitable, an alternative can be selected with either the `--vfs VFSNAME` option or the `FOSSIL_VFS` environment variable. The `--vfs` option takes precedence. ### <a name="temp"></a>Temporary File Location Fossil places some temporary files in the checkout directory. Most notably, supporting files related to merge conflicts are placed in the same folder as the merge result. Other temporary files need a different home. The rules for choosing one are complicated. Fossil-specific code uses `FOSSIL_TEMP`, `TEMP`, and `TMP`, in that order. Fossil’s own test suite prepends `FOSSIL_TEST_TEMP` to that list. The underlying SQLite code uses several different path sets for its temp files, depending on the platform type. On Unix-like platforms, excepting Cygwin, SQLite first checks the environment variables `SQLITE_TMPDIR` and `TMPDIR`, in that order. If neither is defined, it falls back to a hard-coded list of paths: `/var/tmp`, `/usr/tmp`, and `/tmp`. If all of that fails, it uses the current working directory. For Cygwin builds, SQLite instead uses the first defined variable in this list: `SQLITE_TMPDIR`, `TMPDIR`, `TMP`, `TEMP`, and `USERPROFILE`. For native Windows builds, SQLite simply calls the OS’s [`GetTempPath()` API][gtp]. See that reference page for details. [gtp]: https://msdn.microsoft.com/en-us/library/windows/desktop/aa364992%28v=vs.85%29.aspx That said, it is not unusual for utilities on all platforms to assume that `TEMP` or `TMP` point somewhere safe for temporary files. If the identified temporary folder is not writable, then weird things will happen on all platforms. ### Web browser Occasionally, fossil wants to launch a web browser for the user, most obviously as part of the `fossil ui` command. In that specific case, the browser is launched pointing at the web server started by `fossil ui` listening on a private TCP port. On all platforms, if the local or global settings `web-browser` is set, that is the command used to open an URL. Otherwise, the specific actions vary by platform. On Unix-like platforms other than Apple's, it looks for the first program from the list `xdg-open`, `gnome-open`, `firefox`, and `google-chrome` that it can find on the `PATH`. On Apple platforms, it assumes that `open` is the command to open an URL in the user's configured default browser. On Windows platforms, it assumes that `start` is the command to open an URL in the user's configured default browser.

Each technote causes a single entry to appear on the [/timeline?y=e | Timeline Page]. Clicking on the timeline link will display the text of the technote. The wiki content, the timeline entry text, the time of the technote, and the timeline background color can all be edited. As with check-ins, wiki, and tickets, all technotes automatically synchronize to other repositories. Hence, technotes can be viewed, created, and edited off-line. And the complete edit history for technotes is maintained for auditing purposes. Possible uses for technotes include: * <b>Milestones</b>. Project milestones, such as releases or beta-test cycles, can be recorded as technotes. The timeline entry for the technote can be something simple like "Version 1.2.3" perhaps with a bright color background to draw attention to the entry and the wiki content can contain release notes, for example. * <b>Blog Entries</b>. Blog entries from developers describing the current state of a project, or rationale for various design decisions, or roadmaps for future development, can be entered as technotes. * <b>Process Checkpoints</b>. For projects that have a formal process, technotes can be used to record the completion or the initiation of various process steps. For example, a technote can be used to record the successful completion of a long-running test, perhaps with performance results and details of where the test was run and who ran it recorded in the wiki content. * <b>News Articles</b>. Significant occurrences in the life cycle of a project can be recorded as news articles using technotes. Perhaps the domain name of the canonical website for a project changes, or new server hardware is obtained. Such happenings are appropriate for reporting as news. * <b>Announcements</b>. Changes to the composition of the development team or acquisition of new project sponsors can be communicated as announcements which can be implemented as technotes. No project is required to use technotes. But technotes can help many projects stay better organized and provide a better historical record of the development progress. <h2>Viewing Technotes</h2> Because technotes are considered a special kind of wiki, users must have permission to read wiki in order read technotes. Enable the "j" permission under the /Setup/Users menu in order to give specific users or user classes the ability to view wiki and technotes. Technotes show up on the timeline. Click on the hyperlink beside the technote title to see the complete text. <h2>Creating And Editing Technotes</h2> There is a hyperlink under the /wikihelp menu that can be used to create new technotes. And there is a submenu hyperlink on technote displays for editing existing technotes. Users must have check-in privileges (permission "i") in order to create or edit technotes. In addition, users must have create-wiki privilege (permission "f") to create new technotes and edit-wiki privilege (permission "k") in order to edit existing technotes. Technote content may be formatted as [/wiki_rules | Fossil wiki], [/md_rules | Markdown], or a plain text. |

In order to "activate" it, a user with [the "setup" permission](./caps/index.md) must set the [fileedit-glob](/help?cmd=fileedit-glob) repository setting to a comma- or newline-delimited list of globs representing a whitelist of files which may be edited online. Any user with commit access may then edit files matching one of those globs. Certain pages within the UI get an "edit" link added to them when the current user's permissions and the whitelist both permit editing of that file. ## CSRF & HTTP Referrer Headers In order to protect against [Cross-site Request Forgery (CSRF)][csrf] attacks, Fossil UI features which write to the database require that the browser send the so-called [HTTP `Referer` header][referer] (noting that the misspelling of "referrer" is a historical accident which has long-since been standardized!). Modern browsers, by default, include such information automatically for *interactive* actions which lead to a request, e.g. clicking on a link back to the same server. However, `/fileedit` uses asynchronous ["XHR"][xhr] connections, which browsers *may* treat differently than strictly interactive elements. - **Firefox**: configuration option `network.http.sendRefererHeader` specifies whether the `Referer` header is sent. It must have a value of 2 (which is the default) for XHR requests to get the `Referer` header. Purely interactive Fossil features, in which users directly activate links or forms, work with a level of 1 or higher. - **Chrome**: apparently requires an add-on in order to change this policy, so Chrome without such an add-on will not suppress this header. - **Safari**: ??? - **Other browsers**: ??? If `/filepage` shows an error message saying "CSRF violation," the problem is that the browser is not sending a `Referer` header to XHR connections. Fossil does not offer a way to disable its CSRF protections. [referer]: https://en.wikipedia.org/wiki/HTTP_referer [csrf]: https://en.wikipedia.org/wiki/Cross-site_request_forgery [xhr]: https://en.wikipedia.org/wiki/XMLHttpRequest ## `/fileedit` **Works by Creating Commits** Thus any edits made via that page become a normal part of the repository's blockchain. ## `/fileedit` is *Intended* for use with Embedded Docs ... and similar text files, and is most certainly **not intended for editing code**. Editing files with unusual syntax requirements, e.g. hard tabs in makefiles, may break them. *You Have Been Warned.* Similarly, though every effort is made to retain the end-of-line style used by being-edited files, the round-trip through an HTML textarea element may change the EOLs. The Commit section of the page offers three different options for how to treat newlines when saving changes. **Files with mixed EOL styles** *will be normalized to a single EOL style* when modified using `/fileedit`. When "inheriting" the EOL style from a previous version which has mixed styles, the first EOL style detected in the previous version of the file is used. ## `/fileedit` **is Not a Replacement for a Checkout** A full-featured checkout allows far more possibilities than this basic online editor permits, and the feature scope of `/fileedit` is intentionally kept small, implementing only the bare necessities needed for performing basic edits online. It *is not, and will never be, a replacement for a checkout.* It is to be expected that users will want to do "more" with this page, and we generally encourage feature requests, but be aware that certain types of ostensibly sensible feature requests *will be rejected* for `/fileedit`. These include, but are not limited to: - Features which are already provided by other pages, e.g. the ability to create a new named branch or add tags. - Features which would require re-implementing significant capabilities provided only within a checkout (e.g. merging files). - The ability to edit/manipulate files which are in a local checkout. (If you have a checkout, use your local editor, not `/fileedit`.) - Editing of non-text files, e.g. images. Use a checkout and your preferred graphics editor. - Support for syncing/pulling/pushing of a repository before and/or after edits. Those features cannot be *reliably* provided via a web interface for several reasons. Similarly, some *potential* features have significant downsides, abuses, and/or implementation hurdles which make the decision of whether or not to implement them subject to notable contributor debate. e.g. the ability to add new files or remove/rename older files. ## `/fileedit` **Stores Only Limited Local Edits While Working** When changes are made to a given checkin/file combination, `/fileedit` will, if possible, store them in [`window.localStorage` or `window.sessionStorage`][html5storage], if available, but... - Which storage is used is unspecified and may differ across environments. - If neither of those is available, the storage is transient and will not survive a page reload. In this case, the UI issues a clear warning in the editor tab. - It stores only the most recent checkin/file combinations which have been modified (exactly how many may differ - the number will be noted somewhere in the UI). Note that changing the "executable bit" is counted as a modification, but the checkin *comment* is *not* and is reset after a commit. - If its internal limit on the number of modified files is exceeded, it silently discards the oldest edits to keep the list at its limit. Edits are saved whenever the editor component fires its "change" event, which essentially means as soon as it loses input focus. Thus to force the browser to save any pending changes, simply click somwhere on the page outside of the editor. Exactly how long `localStorage` will survive, and how much it or `sessionStorage` can hold, is environment-dependent. `sessionStorage` will survive until the current browser tab is closed, but it survives across reloads of the same tab. If `/filepage` determines that no peristent storage is available a warning is displayed on the editor page. [html5storage]: https://developer.mozilla.org/en-US/docs/Web/API/Web_Storage_API ## The Power is Yours, but... > "With great power comes great responsibility." **Use this feature judiciously, *if at all*.** Now, with those warnings and caveats out of the way... ----- # Tips and Tricks ## `fossil` Global-scope JS Object `/fileedit` is largely implemented in JavaScript, and makes heavy use of the global-scope `fossil` object, which provides infrastructure-level features intended for use by Fossil UI pages. (That said, that infrastructure was introduced with `/fileedit`, and most pages do not use it.) The `fossil.page` object represents the UI's current page (on pages which make use of this API - most do not). That object supports listening to page-specific events so that JS code installed via [client-side edits to the site skin's footer](customskin.md) may react to those changes somehow. The next section describes one such use for such events... ## Integrating Syntax Highlighting Assuming a repository has integrated a 3rd-party syntax highlighting solution, it can probably (depending on its API) be told how to highlight `/fileedit`'s wiki/markdown-format previews. Here are instructions for doing so with [highlightjs](https://highlightjs.org/): At the very bottom of the [site skin's footer](customskin.md), add a script tag similar to the following: ```javascript <script nonce="$<nonce>"> if(window.fossil && fossil.page && fossil.page.name==='fileedit'){ fossil.page.addEventListener( 'fileedit-preview-updated', (ev)=>{ if(ev.detail.previewMode==='wiki'){ ev.detail.element.querySelectorAll( 'code[class^=language-]' ).forEach((e)=>hljs.highlightBlock(e)); } } ); } </script> ``` Note that the `nonce="$<nonce>"` part is intended to be entered literally as shown above. It will be expanded to contain the current request's nonce value when the page is rendered. The first line of the script just ensures that the expected JS-level infrastructure is loaded. It's only loaded in the `/fileedit` page and possibly pages added or "upgraded" since `/fileedit`'s introduction. The part in the `if` block adds an event listener to the `/filepage` app which gets called when the preview is refreshed. That event contains 3 properties: - `previewMode`: a string describing the current preview mode: `wiki` (which includes Fossil-native wiki and markdown), `text`, `htmlInline`, `htmlIframe`. We should "probably" only highlight wiki text, and thus the example above limits its work to that type of preview. It won't work with `htmlIframe`, as that represents an iframe element which contains a complete HTML document. - `element`: the DOM element in which the preview is rendered. - `mimetype`: the mimetype of the being-previewed content, as determined by Fossil (by its file extension). The event listener callback shown above doesn't use the `mimetype`, but makes used of the other two. It fishes all `code` blocks out of the preview which explicitly have a CSS class named `language-`something, and then asks highlightjs to highlight them. ## Integrating a Custom Editor Widget *Hypothetically*, though this is currently unproven "in the wild," it is possible to replace `/filepage`'s basic text-editing widget (a `textarea` element) with a fancy 3rd-party editor widget by following these instructions... All JavaScript code which follows is assumed to be in a script tag similar to the one shown in the previous section: ```javascript <script nonce="$<nonce>"> if(window.fossil && fossil.page && fossil.page.name==='fileedit'){ // code specific to the fileedit page goes here } </script> ``` First, install proxy functions so that `fossil.page.fileContent()` can get and set your content: ``` fossil.page.setContentMethods( function(){ return text-form content of your widget }, function(content){ set text-form content of your widget } }; ``` Secondly, inject the custom editor widget into the UI, replacing the default editor widget: ```javascript fossil.page.replaceEditorWidget(yourNewWidgetElement); ``` That method must be passed a DOM element and may only be called once: it *removes itself* the first time it is called. That "should" be all there is to it. When `fossil.page` needs to get the being-edited content, it will call `fossil.page.fileContent()` with no arguments, and when it sets the content (immediately after (re)loading a file), it will pass that content to `fossil.page.fileContent()`. Those, in turn will trigger the installed proxies and fire any relevant events. |

</h1> The global state of a fossil repository is kept simple so that it can endure in useful form for decades or centuries. A fossil repository is intended to be readable, searchable, and extensible by people not yet born. The global state of a fossil repository is an unordered set of <i>artifacts</i>. An artifact might be a source code file, the text of a wiki page, part of a trouble ticket, a description of a check-in including all the files in that check-in with the check-in comment and so forth. Artifacts are broadly grouped into two types: content artifacts and structural artifacts. Content artifacts are the raw project source-code files that are checked into the repository. Structural artifacts have special formatting rules and are used to show the relationships between other artifacts in the repository. It is possible for an artifact to be both a structure artifact and a content artifact, though this is rare. Artifacts can be text or binary. In addition to the global state, each fossil repository also contains local state. The local state consists of web-page formatting preferences, authorized users, ticket display and reporting formats, and so forth. The global state is shared in common among all repositories for the same project, whereas the local state is often different in separate repositories. The local state is not versioned and is not synchronized with the global state. The local state is not composed of artifacts and is not intended to be enduring. This document is concerned with global state only. Local state is only mentioned here in order to distinguish it from global state. <a name="names"></a> <h2>1.0 Artifact Names</h2> Each artifact in the repository is named by a hash of its content. No prefixes, suffixes, or other information is added to an artifact before the hash is computed. The artifact name is just the (lower-case hexadecimal) hash of the raw artifact. Fossil currently computes artifact names using either SHA1 or SHA3-256. It is relatively easy to add new algorithms in the future, but there are no plans to do so at this time. When referring to artifacts in using tty commands or webpage URLs, it is sufficient to specify a unique prefix for the artifact name. If the input prefix is not unique, Fossil will show an error. Within a structural artifact, however, all references to other artifacts must be the complete hash. Prior to Fossil version 2.0, all names were formed from the SHA1 hash of the artifact. The key innovation in Fossil 2.0 was adding support for alternative hash algorithms. <a name="structural"></a> <h2>2.0 Structural Artifacts</h2> A structural artifact is an artifact with a particular format that is used to define the relationships between other artifacts in the repository. Fossil recognizes the following kinds of structural artifacts: <ul> <li> [#manifest | Manifests] </li> <li> [#cluster | Clusters] </li> <li> [#ctrl | Control Artifacts] </li> <li> [#wikichng | Wiki Pages] </li> <li> [#tktchng | Ticket Changes] </li> <li> [#attachment | Attachments] </li> <li> [#event | TechNotes] </li> <li> [#forum | Forum Posts] </li> </ul> These eight structural artifact types are described in subsections below. Structural artifacts are ASCII text. The artifact may be PGP clearsigned. After removal of the PGP clearsign header and suffix (if any) a structural artifact consists of one or more "cards" separated by a single newline (ASCII: 0x0a) character. Each card begins with a single character "card type". Zero or more arguments may follow the card type. All arguments are separated from each other and from the card-type character by a single space character. There is no surplus white space between arguments and no leading or trailing whitespace except for the newline character that acts as the card separator. All cards must be in strict lexicographical order. There may not be any duplicate cards. In the current implementation (as of 2017-02-27) the artifacts that make up a fossil repository are stored as delta- and zlib-compressed blobs in an <a href="http://www.sqlite.org/">SQLite</a> database. This is an implementation detail and might change in a future release. For the purpose of this article "file format" means the format of the artifacts, not how the artifacts are stored on disk. It is the artifact format that is intended to be enduring. The specifics of how artifacts are stored on disk, though stable, is not intended to live as long as the artifact format. <a name="manifest"></a> <h3>2.1 The Manifest</h3> A manifest defines a check-in. A manifest contains a list of artifacts for each file in the project and the corresponding filenames, as well as information such as parent check-ins, the username of the programmer who created the check-in, the date and time when the check-in was created, and any check-in comments associated with the check-in. Allowed cards in the manifest are as follows: <blockquote> <b>B</b> <i>baseline-manifest</i><br> <b>C</b> <i>checkin-comment</i><br> <b>D</b> <i>time-and-date-stamp</i><br> <b>F</b> <i>filename</i> ?<i>hash</i>? ?<i>permissions</i>? ?<i>old-name</i>?<br> <b>N</b> <i>mimetype</i><br> <b>P</b> <i>artifact-hash</i>+<br> <b>Q</b> (<b>+</b>|<b>-</b>)<i>artifact-hash</i> ?<i>artifact-hash</i>?<br> <b>R</b> <i>repository-checksum</i><br> <b>T</b> (<b>+</b>|<b>-</b>|<b>*</b>)<i>tag-name</i> <b>*</b> ?<i>value</i>?<br> <b>U</b> <i>user-login</i><br> <b>Z</b> <i>manifest-checksum</i> </blockquote> A manifest may optionally have a single <b>B</b> card. The <b>B</b> card specifies another manifest that serves as the "baseline" for this manifest. A manifest that has a <b>B</b> card is called a delta-manifest and a manifest that omits the <b>B</b> card is a baseline-manifest. The other manifest identified by the argument of the <b>B</b> card must be a baseline-manifest. A baseline-manifest records the complete contents of a check-in. A delta-manifest records only changes from its baseline. A manifest must have exactly one <b>C</b> card. The sole argument to the <b>C</b> card is a check-in comment that describes the check-in that the manifest defines. The check-in comment is text. The following escape sequences are applied to the text: A space (ASCII 0x20) is represented as "\s" (ASCII 0x5C, 0x73). A newline (ASCII 0x0a) is "\n" (ASCII 0x5C, x6E). A backslash (ASCII 0x5C) is represented as two backslashes "\\". Apart from space and newline, no other whitespace characters are allowed in the check-in comment. Nor are any unprintable characters allowed in the comment. A manifest must have exactly one <b>D</b> card. The sole argument to the <b>D</b> card is a date-time stamp in the ISO8601 format. The date and time should be in coordinated universal time (UTC). The format one of: <blockquote> <i>YYYY</i><b>-</b><i>MM</i><b>-</b><i>DD</i><b>T</b><i>HH</i><b>:</b><i>MM</i><b>:</b><i>SS</i><br> <i>YYYY</i><b>-</b><i>MM</i><b>-</b><i>DD</i><b>T</b><i>HH</i><b>:</b><i>MM</i><b>:</b><i>SS</i><b>.</b><i>SSS</i> </blockquote> A manifest has zero or more <b>F</b> cards. Each <b>F</b> card identifies a file that is part of the check-in. There are one, two, three, or four arguments. The first argument is the pathname of the file in the check-in relative to the root of the project file hierarchy. No ".." or "." directories are allowed within the filename. Space characters are escaped as in <b>C</b> card comment text. Backslash characters and newlines are not allowed within filenames. The directory separator character is a forward slash (ASCII 0x2F). The second argument to the <b>F</b> card is the lower-case hexadecimal artifact hash of the content artifact. The second argument is required for baseline manifests but is optional for delta manifests. When the second argument to the <b>F</b> card is omitted, it means that the file has been deleted relative to the baseline (files removed in baseline manifests versions are <em>not</em> added as <b>F</b> cards). The optional 3rd argument defines any special access permissions associated with the file. This can be defined as "x" to mean that the file is executable or "l" (small letter ell) to mean a symlink. All files are always readable and writable. This can be expressed by "w" permission if desired but is optional. The file format might be extended with new permission letters in the future. The optional 4th argument is the name of the same file as it existed in the parent check-in. If the name of the file is unchanged from its parent, then the 4th argument is omitted. A manifest has zero or one <b>N</b> cards. The <b>N</b> card specifies the mimetype for the text in the comment of the <b>C</b> card. If the <b>N</b> card is omitted, a default mimetype is used. A manifest has zero or one <b>P</b> cards. Most manifests have one <b>P</b> card. The <b>P</b> card has a varying number of arguments that define other manifests from which the current manifest is derived. Each argument is a lowercase hexadecimal artifact hash of a predecessor manifest. All arguments to the <b>P</b> card must be unique within that card. The first argument is the artifact hash of the direct ancestor of the manifest. Other arguments define manifests with which the first was merged to yield the current manifest. Most manifests have a <b>P</b> card with a single argument. The first manifest in the project has no ancestors and thus has no <b>P</b> card or (depending on the Fossil version) an empty <b>P</b> card (no arguments). A manifest has zero or more <b>Q</b> cards. A <b>Q</b> card is similar to a <b>P</b> card in that it defines a predecessor to the current check-in. But whereas a <b>P</b> card defines the immediate ancestor or a merge ancestor, the <b>Q</b> card is used to identify a single check-in or a small range of check-ins which were cherry-picked for inclusion in or exclusion from the current manifest. The first argument of the <b>Q</b> card is the artifact ID of another manifest (the "target") which has had its changes included or excluded in the current manifest. The target is preceded by "+" or "-" to show inclusion or exclusion, respectively. The optional second argument to the <b>Q</b> card is another manifest artifact ID which is the "baseline" for the cherry-pick. If omitted, the baseline is the primary parent of the target. The changes included or excluded consist of all changes moving from the baseline to the target. The <b>Q</b> card was added to the interface specification on 2011-02-26. Older versions of Fossil will reject manifests that contain <b>Q</b> cards. A manifest may optionally have a single <b>R</b> card. The <b>R</b> card has a single argument which is the MD5 checksum of all files in the check-in except the manifest itself. The checksum is expressed as 32 characters of lowercase hexadecimal. The checksum is computed as follows: For each file in the check-in (except for the manifest itself) in strict sorted lexicographical order, take the pathname of the file relative to the root of the repository, append a single space (ASCII 0x20), the size of the file in ASCII decimal, a single newline character (ASCII 0x0A), and the complete text of the file. Compute the MD5 checksum of the result. A manifest might contain one or more <b>T</b> cards used to set [./branching.wiki#tags | tags or properties] on the check-in. The format of the <b>T</b> card is the same as described in <i>Control Artifacts</i> section below, except that the second argument is the single character "<b>*</b>" instead of an artifact ID. The <b>*</b> in place of the artifact ID indicates that the tag or property applies to the current artifact. It is not possible to encode the current artifact ID as part of an artifact, since the act of inserting the artifact ID would change the artifact ID, hence a <b>*</b> is used to represent "self". <b>T</b> cards are typically added to manifests in order to set the <b>branch</b> property and a symbolic name when the check-in is intended to start a new branch. Each manifest has a single <b>U</b> card. The argument to the <b>U</b> card is the login of the user who created the manifest. The login name is encoded using the same character escapes as is used for the check-in comment argument to the <b>C</b> card. A manifest must have a single <b>Z</b> card as its last line. The argument to the <b>Z</b> card is a 32-character lowercase hexadecimal MD5 hash of all prior lines of the manifest up to and including the newline character that immediately precedes the "Z", excluding any PGP clear-signing prefix. The <b>Z</b> card is a sanity check to prove that the manifest is well-formed and consistent. A sample manifest from Fossil itself can be seen [/artifact/28987096ac | here]. <a name="cluster"></a> <h3>2.2 Clusters</h3> A cluster is an artifact that declares the existence of other artifacts. Clusters are used during repository synchronization to help reduce network traffic. As such, clusters are an optimization and may be removed from a repository without loss or damage to the underlying project code. Allowed cards in the cluster are as follows: <blockquote> <b>M</b> <i>artifact-id</i><br /> <b>Z</b> <i>checksum</i> </blockquote> A cluster contains one or more <b>M</b> cards followed by a single <b>Z</b> card. Each <b>M</b> card has a single argument which is the artifact ID of another artifact in the repository. The <b>Z</b> card works exactly like the <b>Z</b> card of a manifest. The argument to the <b>Z</b> card is the lower-case hexadecimal representation of the MD5 checksum of all prior cards in the cluster. The <b>Z</b> card is required. An example cluster from Fossil can be seen [/artifact/d03dbdd73a2a8 | here]. <a name="ctrl"></a> <h3>2.3 Control Artifacts</h3> Control artifacts are used to assign properties to other artifacts within the repository. Allowed cards in a control artifact are as follows: <blockquote> <b>D</b> <i>time-and-date-stamp</i><br /> <b>T</b> (<b>+</b>|<b>-</b>|<b>*</b>)<i>tag-name</i> <i>artifact-id</i> ?<i>value</i>?<br /> <b>U</b> <i>user-name</i><br /> <b>Z</b> <i>checksum</i><br /> </blockquote> A control artifact must have one <b>D</b> card, one <b>U</b> card, one <b>Z</b> card and one or more <b>T</b> cards. No other cards or other text is allowed in a control artifact. Control artifacts might be PGP clearsigned. The <b>D</b> card and the <b>Z</b> card of a control artifact are the same as in a manifest. The <b>T</b> card represents a [./branching.wiki#tags | tag or property] that is applied to some other artifact. The <b>T</b> card has two or three values. The second argument is the lowercase artifact ID of the artifact to which the tag is to be applied. The first value is the tag name. The first character of the tag is either "+", "-", or "*". The "+" means the tag should be added to the artifact. The "-" means the tag should be removed. The "*" character means the tag should be added to the artifact and all direct descendants (but not descendants through a merge) down to but not including the first descendant that contains a more recent "-", "*", or "+" tag with the same name. The optional third argument is the value of the tag. A tag without a value is a Boolean. When two or more tags with the same name are applied to the same artifact, the tag with the latest (most recent) date is used. Some tags have special meaning. The "comment" tag when applied to a check-in will override the check-in comment of that check-in for display purposes. The "user" tag overrides the name of the check-in user. The "date" tag overrides the check-in date. The "branch" tag sets the name of the branch that at check-in belongs to. Symbolic tags begin with the "sym-" prefix. The <b>U</b> card is the name of the user that created the control artifact. The <b>Z</b> card is the usual required artifact checksum. An example control artifacts can be seen [/info/9d302ccda8 | here]. <a name="wikichng"></a> <h3>2.4 Wiki Pages</h3> A wiki artifact defines a single version of a single wiki page. Wiki artifacts accept the following card types: <blockquote> <b>C</b> <i>change-comment</i><br> <b>D</b> <i>time-and-date-stamp</i><br /> <b>L</b> <i>wiki-title</i><br /> <b>N</b> <i>mimetype</i><br /> <b>P</b> <i>parent-artifact-id</i>+<br /> <b>U</b> <i>user-name</i><br /> <b>W</b> <i>size</i> <b>\n</b> <i>text</i> <b>\n</b><br /> <b>Z</b> <i>checksum</i> </blockquote> The <b>D</b> card is the date and time when the wiki page was edited. The <b>P</b> card specifies the parent wiki pages, if any. The <b>L</b> card gives the name of the wiki page. The optional <b>N</b> card specifies the mimetype of the wiki text. If the <b>N</b> card is omitted, the mimetype is assumed to be text/x-fossil-wiki. The <b>U</b> card specifies the login of the user who made this edit to the wiki page. The <b>Z</b> card is the usual checksum over the entire artifact and is required. The <b>W</b> card is used to specify the text of the wiki page. The argument to the <b>W</b> card is an integer which is the number of bytes of text in the wiki page. That text follows the newline character that terminates the <b>W</b> card. The wiki text is always followed by one extra newline. The <b>C</b> card on a wiki page is optional. The argument is a comment that explains why the changes was made. The ability to have a <b>C</b> card on a wiki page artifact was added on 2019-12-02 at the suggestion of user George Krivov and is not currently used or generated by the implementation. Older versions of Fossil will reject a wiki-page artifact that includes a <b>C</b> card. An example wiki artifact can be seen [/artifact?name=7b2f5fd0e0&txt=1 | here]. <a name="tktchng"></a> <h3>2.5 Ticket Changes</h3> A ticket-change artifact represents a change to a trouble ticket. The following cards are allowed on a ticket change artifact: <blockquote> <b>D</b> <i>time-and-date-stamp</i><br /> <b>J</b> ?<b>+</b>?<i>name</i> ?<i>value</i>?<br /> <b>K</b> <i>ticket-id</i><br /> <b>U</b> <i>user-name</i><br /> <b>Z</b> <i>checksum</i> </blockquote> The <b>D</b> card is the usual date and time stamp and represents the point in time when the change was entered. The <b>U</b> card is the login of the programmer who entered this change. The <b>Z</b> card is the required checksum over the entire artifact. Every ticket has a distinct ticket-id: 40-character lower-case hexadecimal number. The ticket-id is given in the <b>K</b> card. A ticket exists if it contains one or more changes. The first "change" to a ticket is what brings the ticket into existence. <b>J</b> cards specify changes to the "value" of "fields" in the ticket. If the <i>value</i> parameter of the <b>J</b> card is omitted, then the field is set to an empty string. Each fossil server has a ticket configuration which specifies the fields its understands. The ticket configuration is part of the local state for the repository and thus can vary from one repository to another. Hence a <b>J</b> card might specify a <i>field</i> that do not exist in the local ticket configuration. If a <b>J</b> card specifies a <i>field</i> that is not in the local configuration, then that <b>J</b> card is simply ignored. The first argument of the <b>J</b> card is the field name. The second value is the field value. If the field name begins with "+" then the value is appended to the prior value. Otherwise, the value on the <b>J</b> card replaces any previous value of the field. The field name and value are both encoded using the character escapes defined for the <b>C</b> card of a manifest. An example ticket-change artifact can be seen [/artifact/91f1ec6af053 | here]. <a name="attachment"></a> <h3>2.6 Attachments</h3> An attachment artifact associates some other artifact that is the attachment (the source artifact) with a ticket or wiki page or technical note to which the attachment is connected (the target artifact). The following cards are allowed on an attachment artifact: <blockquote> <b>A</b> <i>filename target</i> ?<i>source</i>?<br /> <b>C</b> <i>comment</i><br /> <b>D</b> <i>time-and-date-stamp</i><br /> <b>N</b> <i>mimetype</i><br /> <b>U</b> <i>user-name</i><br /> <b>Z</b> <i>checksum</i> </blockquote> The <b>A</b> card specifies a filename for the attachment in its first argument. The second argument to the <b>A</b> card is the name of the wiki page or ticket or technical note to which the attachment is connected. The third argument is either missing or else it is the lower-case artifact ID of the attachment itself. A missing third argument means that the attachment should be deleted. The <b>C</b> card is an optional comment describing what the attachment is about. The <b>C</b> card is optional, but there can only be one. A single <b>D</b> card is required to give the date and time when the attachment was applied. There may be zero or one <b>N</b> cards. The <b>N</b> card specifies the mimetype of the comment text provided in the <b>C</b> card. If the <b>N</b> card is omitted, the <b>C</b> card mimetype is taken to be text/plain. A single <b>U</b> card gives the name of the user who added the attachment. If an attachment is added anonymously, then the <b>U</b> card may be omitted. The <b>Z</b> card is the usual checksum over the rest of the attachment artifact. The <b>Z</b> card is required. <a name="event"></a> <h3>2.7 Technical Notes</h3> A technical note or "technote" artifact (formerly known as an "event" artifact) associates a timeline comment and a page of text (similar to a wiki page) with a point in time. Technotes can be used to record project milestones, release notes, blog entries, process checkpoints, or news articles. The following cards are allowed on an technote artifact: <blockquote> <b>C</b> <i>comment</i><br> <b>D</b> <i>time-and-date-stamp</i><br /> <b>E</b> <i>technote-time</i> <i>technote-id</i><br /> <b>N</b> <i>mimetype</i><br /> <b>P</b> <i>parent-artifact-id</i>+<br /> <b>T</b> <b>+</b><i>tag-name</i> <b>*</b> ?<i>value</i>?<br /> <b>U</b> <i>user-name</i><br /> <b>W</b> <i>size</i> <b>\n</b> <i>text</i> <b>\n</b><br /> <b>Z</b> <i>checksum</i> </blockquote> The <b>C</b> card contains text that is displayed on the timeline for the technote. The <b>C</b> card is optional, but there can only be one. A single <b>D</b> card is required to give the date and time when the technote artifact was created. This is different from the time at which the technote appears on the timeline. A single <b>E</b> card gives the time of the technote (the point on the timeline where the technote is displayed) and a unique identifier for the technote. When there are multiple artifacts with the same technote-id, the one with the most recent <b>D</b> card is the only one used. The technote-id must be a 40-character lower-case hexadecimal string. The optional <b>N</b> card specifies the mimetype of the text of the technote that is contained in the <b>W</b> card. If the <b>N</b> card is omitted, then the <b>W</b> card text mimetype is assumed to be text/x-fossil-wiki, which is the Fossil wiki format. The optional <b>P</b> card specifies a prior technote with the same technote-id from which the current technote is an edit. The <b>P</b> card is a hint to the system that it might be space efficient to store one technote as a delta of the other. A technote might contain one or more <b>T</b> cards used to set [./branching.wiki#tags | tags or properties] on the technote. The format of the <b>T</b> card is the same as described in [#ctrl | Control Artifacts] section above, except that the second argument is the single character "<b>*</b>" instead of an artifact ID and the name is always prefaced by "<b>+</b>". The <b>*</b> in place of the artifact ID indicates that the tag or property applies to the current artifact. It is not possible to encode the current artifact ID as part of an artifact, since the act of inserting the artifact ID would change the artifact ID, hence a <b>*</b> is used to represent "self". The "<b>+</b>" on the name means that tags can only be add and they can only be non-propagating tags. In a technote, <b>T</b> cards are normally used to set the background display color for timelines. The optional <b>U</b> card gives name of the user who entered the technote. A single <b>W</b> card provides wiki text for the document associated with the technote. The format of the <b>W</b> card is exactly the same as for a [#wikichng | wiki artifact]. The <b>Z</b> card is the required checksum over the rest of the artifact. <a name="forum"></a> <h3>2.8 Forum Posts</h3> Forum posts are intended as a mechanism for users and developers to discuss a project. Forum posts are like messages on a mailing list. The following cards are allowed on an forum post artifact: <blockquote> <b>D</b> <i>time-and-date-stamp</i><br /> <b>G</b> <i>thread-root</i><br /> <b>H</b> <i>thread-title</i><br /> <b>I</b> <i>in-reply-to</i><br /> <b>N</b> <i>mimetype</i><br /> <b>P</b> <i>parent-artifact-id</i><br /> <b>U</b> <i>user-name</i><br /> <b>W</b> <i>size</i> <b>\n</b> <i>text</i> <b>\n</b><br /> <b>Z</b> <i>checksum</i> </blockquote> Every forum post must have either one <b>I</b> card and one <b>G</b> card or one <b>H</b> card. Forum posts are organized into topic threads. The initial post for a thread (the root post) has an <b>H</b> card giving the title or subject for that thread. The argument to the <b>H</b> card is a string in the same format as a comment string in a <b>C</b> card. All follow-up posts have an <b>I</b> card that indicates which prior post in the same thread the current forum post is replying to, and a <b>G</b> card specifying the root post for the entire thread. The argument to G and <b>I</b> cards is the artifact hash for the prior forum post to which the card refers. In theory, it is sufficient for follow-up posts to have only an <b>I</b> card, since the <b>G</b> card value could be computed by following a chain of <b>I</b> cards. However, the <b>G</b> card is required in order to associate the artifact with a forum thread in the case where an intermediate artifact in the <b>I</b> card chain is shunned or otherwise becomes unreadable. A single <b>D</b> card is required to give the date and time when the forum post was created. The optional <b>N</b> card specifies the mimetype of the text of the technote that is contained in the <b>W</b> card. If the <b>N</b> card is omitted, then the <b>W</b> card text mimetype is assumed to be text/x-fossil-wiki, which is the Fossil wiki format. The optional <b>P</b> card specifies a prior forum post for which this forum post is an edit. For display purposes, only the child post is shown, though the historical post is retained as a record. If <b>P</b> cards are used and there exist multiple versions of the same forum post, then <b>I</b> cards for other artifacts refer to whichever version of the post was current at the time the reply was made, but <b>G</b> cards refer to the initial, unedited root post for the thread. Thus, following the chain of <b>I</b> cards back to the root of the thread may land on a different post than the one given in the <b>G</b> card. However, following the chain of <b>I</b> cards back to the thread root, then following <b>P</b> cards back to the initial version of the thread root must give the same artifact as is provided by the <b>G</b> card, otherwise the artifact containing the <b>G</b> card is considered invalid and should be ignored. In general, <b>P</b> cards may contain multiple arguments, indicating a merge. But since forum posts cannot be merged, the <b>P</b> card of a forum post may only contain a single argument. The <b>U</b> card gives name of the user who entered the forum post. A single <b>W</b> card provides wiki text for the forum post. The format of the <b>W</b> card is exactly the same as for a [#wikichng | wiki artifact]. The <b>Z</b> card is the required checksum over the rest of the artifact. <a name="summary"></a> <h2>3.0 Card Summary</h2> The following table summarizes the various kinds of cards that appear on Fossil artifacts. A blank entry means that combination of card and artifact is not legal. A number or range of numbers indicates the number of times a card may (or must) appear in the corresponding artifact type. e.g. a value of 1 indicates a required unique card and 1+ indicates that one or more such cards are required. <table border=1 width="100%"> <tr> <th rowspan=2 valign=bottom>Card Format</th> <th colspan=8>Used By</th> </tr> <tr> <th>Manifest</th> <th>Cluster</th> <th>Control</th> <th>Wiki</th> <th>Ticket</th> <th>Attachment</th> <th>Technote</th> <th>Forum</th> </tr> <tr> <td><b>A</b> <i>filename</i> <i>target</i> ?<i>source</i>?</td> <td> </td> <td> </td> <td> </td> <td> </td> <td> </td> <td align=center><b>1</b></td> <td> </td> <td> </td> </tr> <tr> <td><b>B</b> <i>baseline</i></td> <td align=center><b>0-1</b></td> <td> </td> <td> </td> <td> </td> <td> </td> <td> </td> <td> </td> <td> </td> </tr> <tr> <td><b>C</b> <i>comment-text</i></td> <td align=center><b>1</b></td> <td> </td> <td> </td> <td align=center><b>0-1</b></td> <td> </td> <td align=center><b>0-1</b></td> <td align=center><b>0-1</b></td> <td> </td> </tr> <tr> <td><b>D</b> <i>date-time-stamp</i></td> <td align=center><b>1</b></td> <td> </td> <td align=center><b>1</b></td> <td align=center><b>1</b></td> <td align=center><b>1</b></td> <td align=center><b>1</b></td> <td align=center><b>1</b></td> <td align=center><b>1</b></td> </tr> <tr> <td><b>E</b> <i>technote-time technote-id</i></td> <td> </td> <td> </td> <td> </td> <td> </td> <td> </td> <td> </td> <td align=center><b>1</b></td> <td> </td> </tr> <tr> <td><b>F</b> <i>filename</i> ?<i>uuid</i>? ?<i>permissions</i>? ?<i>oldname</i>?</td> <td align=center><b>0+</b></td> <td> </td> <td> </td> <td> </td> <td> </td> <td> </td> <td> </td> <td> </td> </tr> <tr> <td><b>G</b> <i>thread-root</i></td> <td> </td> <td> </td> <td> </td> <td> </td> <td> </td> <td> </td> <td> </td> <td align=center><b>0-1</b></td> </tr> <tr> <td><b>H</b> <i>thread-title</i></td> <td> </td> <td> </td> <td> </td> <td> </td> <td> </td> <td> </td> <td> </td> <td align=center><b>0-1</b></td> </tr> <tr> <td><b>I</b> <i>in-reply-to</i></td> <td> </td> <td> </td> <td> </td> <td> </td> <td> </td> <td> </td> <td> </td> <td align=center><b>0-1</b></td> </tr> <tr> <td><b>J</b> <i>name</i> ?<i>value</i>?</td> <td> </td> <td> </td> <td> </td> <td> </td> <td align=center><b>1+</b></td> <td> </td> <td> </td> <td> </td> </tr> <tr> <td><b>K</b> <i>ticket-uuid</i></td> <td> </td> <td> </td> <td> </td> <td> </td> <td align=center><b>1</b></td> <td> </td> <td> </td> <td> </td> </tr> <tr> <td><b>L</b> <i>wiki-title</i></td> <td> </td> <td> </td> <td> </td> <td align=center><b>1</b></td> <td> </td> <td> </td> <td> </td> <td> </td> </tr> <tr> <td><b>M</b> <i>uuid</i></td> <td> </td> <td align=center><b>1+</b></td> <td> </td> <td> </td> <td> </td> <td> </td> <td> </td> <td> </td> </tr> <tr> <td><b>N</b> <i>mimetype</i></td> <td align=center><b>0-1</b></td> <td> </td> <td> </td> <td align=center><b>0-1</b></td> <td> </td> <td align=center><b>0-1</b></td> <td align=center><b>0-1</b></td> <td align=center><b>0-1</b></td> </tr> <tr> <td><b>P</b> <i>uuid ...</i></td> <td align=center><b>0-1</b></td> <td> </td> <td> </td> <td align=center><b>0-1</b></td> <td> </td> <td> </td> <td align=center><b>0-1</b></td> <td align=center><b>0-1</b></td> </tr> <tr> <td><b>Q</b> (<b>+</b>|<b>-</b>)<i>uuid</i> ?<i>uuid</i>?</td> <td align=center><b>0+</b></td> <td> </td> <td> </td> <td> </td> <td> </td> <td> </td> <td> </td> <td> </td> </tr> <tr> <td><b>R</b> <i>md5sum</i></td> <td align=center><b>0-1</b></td> <td> </td> <td> </td> <td> </td> <td> </td> <td> </td> <td> </td> <td> </td> <tr> <td><b>T</b> (<b>+</b>|<b>*</b>|<b>-</b>)<i>tagname</i> <i>uuid</i> ?<i>value</i>?</td> <td align=center><b>0+</b></td> <td> </td> <td align=center><b>1+</b></td> <td> </td> <td> </td> <td> </td> <td align=center><b>0+</b></td> <td> </td> </tr> <tr> <td><b>U</b> <i>username</i></td> <td align=center><b>1</b></td> <td> </td> <td align=center><b>1</b></td> <td align=center><b>1</b></td> <td align=center><b>1</b></td> <td align=center><b>0-1</b></td> <td align=center><b>0-1</b></td> <td align=center><b>1</b></td> </tr> <tr> <td><b>W</b> <i>size</i> <b>\n</b> <i>text</i> <b>\n</b></td> <td> </td> <td> </td> <td> </td> <td align=center><b>1</b></td> <td> </td> <td> </td> <td align=center><b>1</b></td> <td align=center><b>1</b></td> </tr> <tr> <td><b>Z</b> <i>md5sum</i></td> <td align=center><b>1</b></td> <td align=center><b>1</b></td> <td align=center><b>1</b></td> <td align=center><b>1</b></td> <td align=center><b>1</b></td> <td align=center><b>1</b></td> <td align=center><b>1</b></td> <td align=center><b>1</b></td> </tr> </table> <a name="addenda"></a> <h2>4.0 Addenda</h2> This section contains additional information which may be useful when implementing algorithms described above. <h3>4.1 R-Card Hash Calculation</h3> Given a manifest file named <tt>MF</tt>, the following Bash shell code demonstrates how to compute the value of the <b>R</b> card in that manifest. This example uses manifest [28987096ac]. Lines starting with <tt>#</tt> are shell input and other lines are output. This demonstration assumes that the file versions represented by the input manifest are checked out under the current directory. <nowiki><pre> # head MF -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 C Make\sthe\s"clearsign"\sPGP\ssigning\sdefault\sto\soff.

In that case the shell-generated hash would differ because the <tt>stat</tt> calls will fail to find such files (which are output in encoded form here). That approach also won't work for delta manifests. Calculating the <b>R</b> card for delta manifests requires traversing both the delta and its baseline in lexical order of the files, preferring the delta's copy if both contain a given file. |

Any project complex enough to benefit from being managed by Fossil and which has more than one user can probably also benefit from having a discussion forum. Even if your project has a discussion forum already, there are many benefits to using Fossil's built-in forum feature, some of which you cannot get by using third-party alternatives: * <b>Easy to Administer:</b> Third-party discussion forum and mailing list software tends to be difficult to install, set up, and administer. The Fossil forum feature aims to be as close to zero-configuration as is practical. * <b>Malefactor Resistant:</b> Because Fossil accepts forum posts only via the web UI, it is inherently [./antibot.wiki | protected against bots]. * <b>Distributed and Tamper-Proof:</b> Posts are stored in the Fossil repository using the same [./fileformat.wiki | block chain technology] that Fossil uses to store your check-ins, wiki documents, etc. Posts sync to cloned repositories in a tamper-proof fashion. * <b>Space Efficient:</b> Because of Fossil's [./delta_format.wiki | delta compression technology], discussions add little to the size of a cloned repository. Ten years of the SQLite project's discussions — averaging about 2 dozen posts per day — compress down to [https://fossil-scm.org/forum/forumpost/9b6f3f36bdb | just 35 MB of space] in a Fossil forum repository. * <b>Built-in Full-Text Search:</b> Fossil forums use [https://sqlite.org/fts3.html | SQLite's powerful FTS4 engine] to handle searches. If your project currently uses a mailing list for discussions, this means you are no longer reliant upon third-party mailing list archive services to provide a useful search engine for your discussions. If you are running a private Fossil repository, you may not even have the <em>option</em> of delegating this useful service to a third-party; Fossil provides this service out of the box. * <b>One Result Per Matching Post:</b> When you search the forum archives via the Fossil web interface, you get only one result for each matching post. When you search for project information via a standard web search engine, you might get a result from the project site's own mail archive plus one from Nabble, one from Gmane, one from The Mail Archive... * <b>Search Off-Line:</b> Because Fossil is a [./concepts.wiki | distributed version control system], project members can search your forum archive while disconnected from the network where the central Fossil instance runs. Your past discussions are potentially just as valuable as a wiki document or checkin comment: there is no good reason why you should have to wait to get back on the Internet or back to the office before you can search for past posts. * <b>Contribute Off-Line:</b> Fossil forum posts work like any other insertion into the repository, so a user can create new threads and reply to existing ones while off-line, then sync their contributions to the server they cloned from when back on-line. Yes, you can post to the forum from inside a tent, miles from the nearest WiFi router or cellular data tower. * <b>Interlink with Other Fossil-Managed Artifacts:</b> Because forum posts are normal Fossil artifacts, you can interlink them with other Fossil artifacts using short internal links: link to forum threads from a [./tickets.wiki | ticket], link to a wiki document from a forum post, etc. * <b>Durable Links:</b> Once you create a valid internal artifact link in Fossil, it <em>remains</em> valid, durably. With third-party forum software and mailing list search engines, your links are only valid until the third-party component changes its URL scheme or disappears from the web. * <b>Role-Based Access Control:</b> The forum uses the same [./caps/ | capability-based access control system] that Fossil uses to control all other repository accesses. The Fossil forum feature simply adds [./caps/ref.html#2 | several new fine-grained capabilities] to the existing system. * <b>Enduring, Open File Format:</b> Since Fossil has an [./fileformat.wiki | open and well-documented file format], your discussion archives are truly that: <em>archives</em>. You are no longer dependent on the lifetime and business model of a third-party piece of software or service. Should you choose to stop using Fossil, you can easily extract your discussion traffic for transfer to another system. * <b>Lightweight Markup:</b> Posts can be marked up using Fossil's existing [/md_rules | Markdown] and [/wiki_rules | Wiki] markup processors. No longer must you choose between two bad options: to restrict posts to plain text only or to allow wild-west HTML-formatted MIME email. Fossil's lightweight markup language formatting features give you a middle path, providing your users enough formatting power to communicate complex ideas well without providing so much power as to risk [https://wonko.com/post/html-escaping | security problems]. * <b>Easy Email Alerts:</b> You can configure Fossil to [./alerts.md | send email alerts]. Forum post emails include the complete message content for the benefit of those that prefer to visit the forum only when they need to post something. Alerts are optional, and each user gets the choice of immediate or daily digest delivery. <h2 id="setup">Setting up a Fossil Forum</h2> <h3 id="caps">Capabilities</h3> By default, no Fossil user has permission to use the forums except for users with Setup and Admin capabilities, which get these as part of the large package of other capabilities they get. For public Fossil repositories that wish to accept new users without involving a human, go into Admin → Access and enable the "Allow users to register themselves" setting. You may also wish to give users in [./caps/#ucat | the <tt>anonymous</tt> user category] the <b>[./caps/ref.html#2 | RdForum]</b> and <b>[./caps/ref.html#3 | WrForum]</b> capabilities: this allows people to post without creating an account simply by solving [./antibot.wiki | a simple CAPTCHA]. For a private repository, you probably won't want to give the <tt>anonymous</tt> user any forum access, but you may wish to give the <b>RdForum</b> capability to users in the <tt>reader</tt> category. For either type of repository, you are likely to want to give at least the <b>[./caps/ref.html#4 | WrTForum]</b> capability to users in the <tt>developer</tt> category. If you did not give the <b>RdForum</b> capability to <tt>anonymous</tt> above, you should give <tt>developer</tt> that capability here if you choose to give it <b>WrForum</b> or <b>WrTForum</b> capability. If you want to use the email alert feature, by default only those users in the Setup and Admin user categories can make use of it. Grant the <b>[./caps/ref.html#7 | EmailAlert]</b> capability to give others access to this feature. Alternately, you can handle alert signups outside of Fossil, with a Setup or Admin users manually signing users up via Admin → Notification. You'll want to grant this capability to the <tt>nobody</tt> user category if you want anyone to sign up without any restrictions. Give it to <tt>anonymous</tt> instead if you want the user to solve a simple CAPTCHA before signing up. Or, give it to <tt>reader</tt> or <tt>developer</tt> if you want only users with Fossil logins to have this ability. (That's assuming you give one or both of these capabilities to every user on your Fossil repository.) By following this advice, you should not need to tediously add capabilities to individual accounts except in atypical cases, such as to grant the <b>[./caps/ref.html#5 | ModForum]</b> capability to an uncommonly highly-trusted user. <h3 id="skin">Skin Setup</h3> If you create a new Fossil repository with version 2.7 or newer, its default skin is already set up correctly for typical forum configurations. If you have an existing repository, you have two choices if you want its skin to be upgraded to support forums: <ol> <li>Go into Admin → Skins and switch from your current skin to one of the stock skins. If you were on a stock skin, just switch away from your current one to the actual stock skin, since they will be different after the upgrade.</li> <li>If you have local customization that you do not want to throw away, you can use the diff feature of Fossil's skin editor to show how the skins differ.</li> </ol> The remainder of this section summarizes the differences you're expected to see when taking option #2. The first thing is that you'll need to add something like the following to the Header part of the skin to create the navbar link: <verbatim> if {[anycap 23456] || [anoncap 2] || [anoncap 3]} { menulink /forum Forum } </verbatim> These rules say that any logged-in user with any [./caps/ref.html#2 | forum-related capability] or an anonymous user <b>RdForum</b> or <b>WrForum</b> capability will see the "Forum" navbar link, which just takes you to <tt>/forum</tt>. The exact code you need here varies depending on which skin you're using. Follow the style you see for the other navbar links. The new forum feature also brings many new CSS styles to the table. If you're using the stock skin or something sufficiently close, the changes may work with your existing skin as-is. Otherwise, you might need to adjust some things, such as the background color used for the selected forum post: <verbatim> div.forumSel { background-color: rgba(0, 0, 0, 0.05); } </verbatim> That overrides the default — a hard-coded light cyan — with a 95% transparent black overlay instead, which simply darkens your skin's normal background color underneath the selected post. That should work with almost any background color except for very dark background colors. For dark skins, an inverse of the above trick will work better: <verbatim> div.forumSel { background-color: rgba(255, 255, 255, 0.05); } </verbatim> That overlays the background with 5% white to lighten it slightly. Another new forum-related CSS style you might want to reflect into your existing skin is: <verbatim> div.forumPosts a:visited { color: #6A7F94; } </verbatim> This changes the clicked-hyperlink color for the forum post links on the main <tt>/forum</tt> page only, which allows your browser's history mechanism to show which threads a user has read and which not. The link color will change back to the normal link color — indicating "unread" — when a reply is added to an existing thread because that changes where the link from the <tt>/forum</tt> page points, taking you to the newest post in the thread. The color given above is suitable for the stock skin. Beware that when changing this example, there are some [https://hacks.mozilla.org/2010/03/privacy-related-changes-coming-to-css-vistited/ | stringent restrictions] in modern browsers to prevent snoopy web sites from brute-forcing your browsing history. (See the link for the method, which explains the restrictions.) <h3 id="search">Enable Forum Search</h3> One of the underlying assumptions of the forum feature is that you will want to be able to search the forum archives, so the <tt>/forum</tt> page always includes a search box. Since that depends on search being enabled on the Fossil repository, Fossil warns that search is disabled until you go into Admin → Search and enable the "Search Forum" setting. You may want to enable some of the other Fossil search features while you're in there. All of this does come at some CPU and I/O cost, which is why it's disabled by default. <h3 id="sso">Single Sign-On</h3> If you choose to host your discussion forums within the same repository as your project's other Fossil-managed content, you inherently have a single sign-on system. Contrast third-party mailing list and forum software where you either end up with two separate user tables and permission sets, or you must go to significant effort to integrate the two login systems. You may instead choose to host your forums in a Fossil repository separate from your project's main Fossil repository. A good reason to do this is that you have a public project where very few of those participating in the forum have special capability bits for project assets managed by Fossil, so you wish to segregate the two user sets. Yet, what of the users who will have logins on both repositories? Some users will be trusted with access to the project's main Fossil repository, and these users will probably also participate in the project's Fossil-hosted forum. Fossil has a feature to solve this problem: [./caps/login-groups.md | login groups]. <h3 id="alerts">Email Alerts (a.k.a. Notifications)</h3> Internet email service has become rather complicated since its initial simple and insecure implementation decades ago. Fossil's role in all of this is rather small at the moment, but the details of the integration are complex enough to justify [./alerts.md | a separate document]. (The other reason that document is separate is that Fossil's email alerts system also gets used by features of Fossil other than the forum.) <h2 id="access">Accessing the Forum</h2> There are many paths to a repository's Fossil forum: <ul> <li> If you're using the default Fossil skin as shipped with Fossil 2.7+ or one [#skin | updated] to support it, there is a Forum button in the navbar which appears for users able to access the forum. With the default skin, that button will only appear if the user's browser window is at least 1200 pixels wide. The Fossil admin can adjust this limit in the skin's CSS section, down near the bottom in the definition of the `wideonly` style. </li> <li>The other stock skins have this button in them as of 2.7 as well, without the screen width restriction, since the navbar in those skins wraps on narrow screens more gracefully than the default skin does.</li> <li>Users who set up their Fossil repository under prior versions and who now have local skin changes they don't want to overwrite by reverting to the stock 2.7 version of the skin they chose to start with can easily [#skin | edit their skin] to include these links.</li> <li>A "Forum" link appears in the drop-down panel when you click the default skin's hamburger menu (☰) while logged in as any user with one or more of the [#caps | user capabilities listed above].</li> <li>That same link also appears on the repository's <tt>/sitemap</tt> page, since it provides the content for the hamburger menu's panel.</li> </ul> <h2 id="moderation">How Moderation Works</h2> In this section, we're going to call all of the following a "forum update:" * create a new post * reply to an existing post * edit a post or reply When a person with the normal <b>WrForum</b> capability updates the forum, Fossil saves the update in its block chain, but this update is impermanent because of two other table updates made at the same time: <ol> <li>Fossil saves the update artifact's ID in its <tt>private</tt> table, preventing Fossil from sending such artifacts to any of the repository's clones. (This is the same mechanism behind [./private.wiki | private branches].)</li> <li>Fossil also adds a reference to that artifact in the <tt>modreq</tt> table, which backs the moderation feature. This is what causes Fossil to leave out the Reply button when rendering that post's HTML in the forum's web interface.</li> </ol> When a moderator approves an update, Fossil deletes these table entries, making the update [./shunning.wiki | semi-permanent]. This changes how Fossil renders the HTML for that update. It also means the artifact will now sync to users with <b>[./caps/ref.html#g | Clone]</b> capability. When a forum user edits a moderator-approved artifact, what actually happens under the hood is that Fossil writes another artifact to the repository which refers to the original version as its parent, causing Fossil UI to present the new version instead of the original. The original version remains in the repository, just as with historical checkins. The parent must remain in the repository for referential integrity purposes. When you "Delete" a moderator-approved post or reply through Fossil UI, it's actually an edit with blank replacement content. The only way to truly delete such artifacts is through [./shunning.wiki | shunning]. When a user with <b>WrTForum</b> capability updates the forum, it happens in the same way except that Fossil skips the <tt>private</tt> and <tt>modreq</tt> table insertions. When a moderator rejects an update, that artifact is unceremoniously removed from the tip of the block chain. This is safe because Fossil prevents replies to a reply or post awaiting moderator approval, so referential integrity cannot be harmed. Rejecting an edit is even safer, since the original post remains behind, so that replies continue to refer to that original post. <h2 id="mod-user">Using the Moderation Feature</h2> Having described all of the work that Fossil performs under the hood on behalf of its users, we can now give the short list of work left for the repository's administrators and moderators: <ol> <li>Add the <b>[./caps/ref.html#5 | ModForum]</b> capability to any of your users who should have this ability. You don't need to do this for any user with <b>[./caps/ref.html#s | Setup]</b> or <b>[./caps/ref.html#a | Admin]</b> capability; it's [http://fossil-scm.org/index.html/artifact/b16221ffb736caa2?ln=1246-1257 | already included].</li> <li>When someone updates the forum, an entry will appear in the timeline if the type filter is set to "Forum" or "Any Type". If that user has only the <b>WrForum</b> capability, any other user with the <b>ModForum</b> capability will see a conditional link appear at the top of the main forum page: "Moderation Requests". Clicking this takes the moderator to the <tt>/modreq</tt> page. A moderator may wish to keep the main forum page open in a browser tab, reloading it occasionally to see when the "Moderation Requests" link reappears.</li> <li>A moderator viewing an update pending moderation sees two buttons at the bottom, "Approve" and "Reject" in place of the "Delete" button that the post's creator sees. Beware that both actions are durable and have no undo. Be careful!</li> </ol> |

[http://git-scm.com | Git] overlap in many ways. Both are [https://en.wikipedia.org/wiki/Distributed_version_control | distributed version control systems] which store a tree of check-in objects to a local repository clone. In both systems, the local clone starts out as a full copy of the remote parent. New content gets added to the local clone and then later optionally pushed up to the remote, and changes to the remote can be pulled down to the local clone at will. Both systems offer diffing, patching, branching, merging, cherry-picking, bisecting, private branches, a stash, etc. Fossil has inbound and outbound Git conversion features, so if you start out using one DVCS and later decide you like the other better, you can easily [./inout.wiki | move your version-controlled file content].¹ In this document, we set all of that similarity and interoperability aside and focus on the important differences between the two, especially those that impact the user experience. Keep in mind that you are reading this on a Fossil website, and though we try to be fair, the information here might be biased in favor of Fossil, if only because we spend most of our time using Fossil, not Git. Ask around for second opinions from people who have used <em>both</em> Fossil and Git. <h2>2.0 Differences Between Fossil And Git</h2> Differences between Fossil and Git are summarized by the following table, with further description in the text that follows. <blockquote><table border=1 cellpadding=5 align=center> <tr><th width="49%">GIT</th><th width="49%">FOSSIL</th><th width="2%">more</th></tr> <tr> <td>File versioning only</td> <td>VCS, tickets, wiki, docs, notes, forum, UI, [https://en.wikipedia.org/wiki/Role-based_access_control|RBAC]</td> <td><a href="#features">2.1 ↓</a></td> </tr> <tr> <td>Sprawling and inefficient</td> <td>Self-contained and efficient</td> <td><a href="#efficient">2.2 ↓</a></td> </tr> <tr> <td>One-off custom pile-of-files data store</td> <td>[https://sqlite.org/famous.html|The most popular database in the world]</td> <td><a href="#durable">2.3 ↓</a></td> </tr> <tr> <td>Runs natively on POSIX systems only</td> <td>Native on common desktop & server platforms</td> <td><a href="#portable">2.4 ↓</a></td> </tr> <tr> <td>Bazaar-style development</td> <td>Cathedral-style development</td> <td><a href="#devorg">2.5.1 ↓</a></td> </tr> <tr> <td>Designed for Linux kernel development</td> <td>Designed for SQLite development</td> <td><a href="#scale">2.5.2 ↓</a></td> </tr> <tr> <td>Many contributors</td> <td>Select contributors</td> <td><a href="#contrib">2.5.3 ↓</a></td> </tr> <tr> <td>Focus on individual branches</td> <td>Focus on the entire tree of changes</td> <td><a href="#branches">2.5.4 ↓</a></td> </tr> <tr> <td>One check-out per repository</td> <td>Many check-outs per repository</td> <td><a href="#checkouts">2.6 ↓</a></td> </tr> <tr> <td>Remembers what you should have done</td> <td>Remembers what you actually did</td> <td><a href="#history">2.7 ↓</a></td> </tr> <tr> <td>Commit first</td> <td>Test first</td> <td><a href="#testing">2.8 ↓</a></td> </tr> <tr> <td>SHA-2</td> <td>SHA-3</td> <td><a href="#hash">2.9 ↓</a></td> </tr> </table></blockquote> <h3 id="features">2.1 Featureful</h3> Git provides file versioning services only, whereas Fossil adds an integrated [./wikitheory.wiki | wiki], [./bugtheory.wiki | ticketing & bug tracking], [./embeddeddoc.wiki | embedded documentation], [./event.wiki | technical notes], and a [./forum.wiki | web forum], all within a single nicely-designed [./customskin.md|skinnable] web [/help?cmd=ui|UI], protected by [./caps/ | a fine-grained role-based access control system]. These additional capabilities are available for Git as 3rd-party add-ons, but with Fossil they are integrated into the design. One way to describe Fossil is that it is "[https://github.com/ | GitHub]-in-a-box." Fossil can do operations over all local repo clones and check-out directories with a single command. For example, Fossil lets you say <tt>fossil all sync</tt> on a laptop prior to taking it off the network hosting those repos. You can sync up to all of the private repos on your company network plus those public Internet-hosted repos you use. Whether going out for a working lunch or on a transoceanic airplane trip, one command gets you in sync. This works with several other Fossil sub-commands, such as <tt>fossil all changes</tt> to get a list of files that you forgot to commit prior to the end of your working day, across all repos. Whenever Fossil is told to modify the local checkout in some destructive way ([/help?cmd=rm|fossil rm], [/help?cmd=update|fossil update], [/help?cmd=revert|fossil revert], etc.) Fossil remembers the prior state and is able to return the check-out directory to that state with a <tt>fossil undo</tt> command. You cannot undo a commit in Fossil ([#history | on purpose!]) but as long as the change remains confined to the local check-out directory only, Fossil makes undo [https://git-scm.com/book/en/v2/Git-Basics-Undoing-Things|easier than in Git]. For developers who choose to self-host projects (rather than using a 3rd-party service such as GitHub) Fossil is much easier to set up, since the stand-alone Fossil executable together with a [./server/any/cgi.md|2-line CGI script] suffice to instantiate a full-featured developer website. To accomplish the same using Git requires locating, installing, configuring, integrating, and managing a wide assortment of separate tools. Standing up a developer website using Fossil can be done in minutes, whereas doing the same using Git requires hours or days. Fossil is small, complete, and self-contained. If you clone [https://github.com/git/git|Git's self-hosting repository], you get just Git's source code. If you clone Fossil's self-hosting repository, you get the entire Fossil website — source code, documentation, ticket history, and so forth.² That means you get a copy of this very article and all of its historical versions, plus the same for all of the other public content on this site. <h3 id="efficient" name="effective">2.2 Efficient</h3> Git is actually a collection of many small tools, each doing one small part of the job, which can be recombined (by experts) to perform powerful operations. Git has a lot of complexity and many dependencies, so that most people end up installing it via some kind of package manager, simply because the creation of complicated binary packages is best delegated to people skilled in their creation. Normal Git users are not expected to build Git from source and install it themselves. Fossil is a single self-contained stand-alone executable which by default depends only on common platform libraries. If your platform allows static linking — not all do these days! — you can even get it down to a single executable with no external dependencies at all. Most notably, we deliver the official Windows builds of Fossil this way: the Zip file contains only <tt>fossil.exe</tt>, a self-contained Fossil executable; it is not a <tt>setup.exe</tt> style installer, it is the whole enchilada. A typical Fossil executable is about 5 MiB, not counting system libraries it shares in common with Git such as OpenSSL and zlib, which we can factor out of the discussion. These properties allow Fossil to easily run inside a minimally configured [https://en.wikipedia.org/wiki/Chroot|chroot jail], from a Windows memory stick, off a Raspberry Pi with a tiny SD card, etc. To install Fossil, one merely puts the executable somewhere in the <tt>$PATH</tt>. Fossil is [https://fossil-scm.org/fossil/doc/trunk/www/build.wiki|straightforward to build and install], so that many Fossil users do in fact build and install "trunk" versions to get new features between formal releases. Contrast a basic installation of Git, which takes up about 15 MiB on Debian 10 across 230 files, not counting the contents of <tt>/usr/share/doc</tt> or <tt>/usr/share/locale</tt>. If you need to deploy to any platform where you cannot count facilities like the POSIX shell, Perl interpreter, and Tcl/Tk platform needed to fully use Git as part of the base platform, the full footprint of a Git installation extends to more like 45 MiB and thousands of files. This complicates several common scenarios: Git for Windows, chrooted Git servers, Docker images... Some say that Git more closely adheres to the Unix philosophy, summarized as "many small tools, loosely joined," but we have many examples of other successful Unix software that violates that principle to good effect, from Apache to Python to ZFS. We can infer from that that this is not an absolute principle of good software design. Sometimes "many features, tightly-coupled" works better. What actually matters is effectiveness and efficiency. We believe Fossil achieves this. The above size comparisons aren't apples-to-apples anyway. We've compared the size of Fossil with all of its [#features | many built-in features] to a fairly minimal Git installation. You must add a lot of third-party software to Git to give it a Fossil-equivalent feature set. Consider [https://about.gitlab.com/|GitLab], a third-party extension to Git wrapping it in many features, making it roughly Fossil-equivalent, though [https://docs.gitlab.com/ee/install/requirements.html|much more resource hungry] and hence more costly to run than the equivalent Fossil setup. GitLab's basic requirements are easy to accept when you're dedicating a local rack server or blade to it, since its minimum requirements are more or less a description of the smallest thing you could call a "server" these days, but when you go to host that in the cloud, you can expect to pay about 8× as much to comfortably host GitLab as for Fossil.³ This difference is largely due to basic technology choices: Ruby and PostgreSQL vs C and SQLite. The Fossil project itself is [./selfhost.wiki|hosted on a very small VPS], and we've received many reports on the Fossil forum about people successfully hosting Fossil service on bare-bones $5/month VPS hosts, spare Raspberry Pi boards, and other small hosts. <h3 id="durable" name="database">2.3 Durable</h3> The baseline data structures for Fossil and Git are the same, modulo formatting details. Both systems manage a [https://en.wikipedia.org/wiki/Directed_acyclic_graph | directed acyclic graph] (DAG) of [https://en.wikipedia.org/wiki/Merkle_tree | Merkle tree] / [./blockchain.md | block chain] structured check-in objects. Check-ins are identified by a cryptographic hash of the check-in contents, and each check-in refers to its parent via <i>its</i> hash. The difference is that Git stores its objects as individual files in the <tt>.git</tt> folder or compressed into bespoke [https://git-scm.com/book/en/v2/Git-Internals-Packfiles|pack-files], whereas Fossil stores its objects in a [https://www.sqlite.org/|SQLite] database file using a hybrid NoSQL/relational data model of the check-in history. Git's data storage system is an ad-hoc pile-of-files key/value database, whereas Fossil uses a proven, [https://sqlite.org/testing.html|heavily-tested], general-purpose, [https://sqlite.org/transactional.html|durable] SQL database. This difference is more than an implementation detail. It has important practical consequences. With Git, one can easily locate the ancestors of a particular check-in by following the pointers embedded in the check-in object, but it is difficult to go the other direction and locate the descendants of a check-in. It is so difficult, in fact, that neither native Git nor GitHub provide this capability short of [http://catb.org/jargon/html/G/grovel.html|groveling] the [https://www.git-scm.com/docs/git-log|commit log]. With Git, if you are looking at some historical check-in then you cannot ask "What came next?" or "What are the children of this check-in?" Fossil, on the other hand, parses essential information about check-ins (parents, children, committers, comments, files changed, etc.) into a relational database that can easily be queried using concise SQL statements to find both ancestors and descendants of a check-in. This is the hybrid data model mentioned above: Fossil manages your check-in and other data in a NoSQL block chain structured data store, but that's backed by a set of relational lookup tables for quick indexing into that artifact store. (See "[./theory1.wiki|Thoughts On The Design Of The Fossil DVCS]" for more details.) Leaf check-ins in Git that lack a "ref" become "detached," making them difficult to locate and subject to garbage collection. This [http://gitfaq.org/articles/what-is-a-detached-head.html|detached head state] problem has caused untold grief for [https://www.google.com/search?q=git+detached+head+state | a huge number of Git users]. With Fossil, detached heads are simply impossible because we can always find our way back into the block chain using one or more of the relational indices it automatically manages for you. This design difference shows up in several other places within each tool. It is why Fossil's [/help?cmd=timeline|timeline] is generally more detailed yet more clear than those available in Git front-ends. (Contrast [/timeline?c=6df7a853ec16865b|this Fossil timeline] with [https://github.com/drhsqlite/fossil-mirror/commits/master?after=f720c106d297ca1f61bccb30c5c191b88a626d01+34|its closest equivalent in GitHub].) It's why there is no inverse of the cryptic <tt>@~</tt> notation in Git, meaning "the parent of HEAD," which Fossil simply calls "prev", but there <i>is</i> a "next" [./checkin_names.wiki|special check-in name] in Fossil. It is why Fossil has so many [./webpage-ex.md|built-in status reports] to help maintain situational awareness, aid comprehension, and avoid errors. These differences are due, in part, to Fossil's start a year later than Git: we were able to learn from its key design mistakes. <h3 id="portable">2.4 Portable</h3> Fossil is largely written in ISO C, almost purely conforming to the original 1989 standard. We make very little use of [https://en.wikipedia.org/wiki/C99|C99], and we do not knowingly make any use of [https://en.wikipedia.org/wiki/C11_(C_standard_revision)|C11]. Fossil does call POSIX and Windows APIs where necessary, but it's about as portable as you can ask given that ISO C doesn't define all of the facilities Fossil needs to do its thing. (Network sockets, file locking, etc.) There are certainly well-known platforms Fossil hasn't been ported to yet, but that's most likely due to lack of interest rather than inherent difficulties in doing the port. We believe the most stringent limit on its portability is that it assumes at least a 32-bit CPU and several megs of flat-addressed memory.â´ Fossil isn't quite as [https://www.sqlite.org/custombuild.html|portable as SQLite], but it's close. Over half of the C code in Fossil is actually an embedded copy of the current version of SQLite. Much of what is Fossil-specific after you set SQLite itself aside is SQL code calling into SQLite. The number of lines of SQL code in Fossil isn't large by percentage, but since SQL is such an expressive, declarative language, it has an outsized contribution to Fossil's user-visible functionality. Fossil isn't entirely C and SQL code. Its web UI [./javascript.md | uses JavaScript where necessary]. The server-side UI scripting uses a custom minimal [https://en.wikipedia.org/wiki/Tcl|Tcl] dialect called [https://www.fossil-scm.org/xfer/doc/trunk/www/th1.md|TH1], which is embedded into Fossil itself. Fossil's build system and test suite are largely based on Tcl.âµ All of this is quite portable. About half of Git's code is POSIX C, and about a third is POSIX shell code. This is largely why the so-called "Git for Windows" distributions (both [https://git-scm.com/download/win|first-party] and [https://gitforwindows.org/|third-party]) are actually an [http://mingw.org/wiki/msys|MSYS POSIX portability environment] bundled with all of the Git stuff, because it would be too painful to port Git natively to Windows. Git is a foreign citizen on Windows, speaking to it only through a translator.ⶠWhile Fossil does lean toward POSIX norms when given a choice — LF-only line endings are treated as first-class citizens over CR+LF, for example — the Windows build of Fossil is truly native. The third-party extensions to Git tend to follow this same pattern. [http://mingw.org/wiki/msys|GitLab isn't portable to Windows at all], for example. For that matter, GitLab isn't even officially supported on macOS, the BSDs, or uncommon Linuxes! We have many users who regularly build and run Fossil on all of these systems. <h3 id="vs-linux">2.5 Linux vs. SQLite</h3> Fossil and Git promote different development styles because each one was specifically designed to support the creator's main software development project: [https://en.wikipedia.org/wiki/Linus_Torvalds|Linus Torvalds] designed Git to support development of [https://www.kernel.org/|the Linux kernel], and [https://en.wikipedia.org/wiki/D._Richard_Hipp|D. Richard Hipp] designed Fossil to support the development of [https://sqlite.org/|SQLite]. Both projects must rank high on any objective list of "most important FOSS projects," yet these two projects are almost entirely unlike one another, so it is natural that the DVCSes created to support these projects also differ in many ways. In the following sections, we will explain how four key differences between the Linux and SQLite software development projects dictated the design of each DVCS's low-friction usage path. When deciding between these two DVCSes, you should ask yourself, "Is my project more like Linux or more like SQLite?" <h4 id="devorg">2.5.1 Development Organization</h4> Eric S. Raymond's seminal essay-turned-book "[https://en.wikipedia.org/wiki/The_Cathedral_and_the_Bazaar|The Cathedral and the Bazaar]" details the two major development organization styles found in [https://en.wikipedia.org/wiki/Free_and_open-source_software|FOSS] projects. As it happens, Linux and SQLite fall on opposite sides of this dichotomy. Differing development organization styles dictate a different design and low-friction usage path in the tools created to support each project. Git promotes the Linux kernel's bazaar development style, in which a loosely-associated mass of developers contribute their work through [https://git-scm.com/book/en/v2/Distributed-Git-Distributed-Workflows#_dictator_and_lieutenants_workflow|a hierarchy of lieutenants] who manage and clean up these contributions for consideration by Linus Torvalds, who has the power to cherry-pick individual contributions into his version of the Linux kernel. Git allows an anonymous developer to rebase and push specific locally-named private branches, so that a Git repo clone often isn't really a clone at all: it may have an arbitrary number of differences relative to the repository it originally cloned from. Git encourages siloed development. Select work in a developer's local repository may remain private indefinitely. All of this is exactly what one wants when doing bazaar-style development. Fossil's normal mode of operation differs on every one of these points, with the specific designed-in goal of promoting SQLite's cathedral development model: <ul> <li><p><b>Personal engagement:</b> SQLite's developers know each other by name and work together daily on the project.</p></li> <li><p><b>Trust over hierarchy:</b> SQLite's developers check changes into their local repository, and these are immediately and automatically synchronized up to the central repository; there is no "[https://git-scm.com/book/en/v2/Distributed-Git-Distributed-Workflows#_dictator_and_lieutenants_workflow|dictator and lieutenants]" hierarchy as with Linux kernel contributions. D. Richard Hipp rarely overrides decisions made by those he has trusted with commit access on his repositories. Fossil allows you to give [./caps/admin-v-setup.md|some users] more power over what they can do with the repository, but Fossil [./caps/index.md#ucap | only loosely supports] the enforcement of a development organization's social and power hierarchies.

Fossil's closest equivalent is its unique [/help?cmd=bundle|bundle] feature, which requires higher engagement than firing off a PR.â· This difference comes directly from the initial designed purpose for each tool: the SQLite project doesn't accept outside contributions from previously-unknown developers, but the Linux kernel does.</p></li> <li><p><b>No rebasing:</b> When your local repo clone syncs changes up to its parent, those changes are sent exactly as they were committed locally.

Fossil is still a truly distributed version control system; it's just that its starting default is to assume you're rarely out of communication with the parent repo. <br><br> This is not merely a reflection of modern always-connected computing environments. It is a conscious decision in direct support of SQLite's cathedral development model: we don't want developers going dark, then showing up weeks later with a massive bolus of changes for us to integrate all at once. [https://en.wikipedia.org/wiki/Jim_McCarthy_(author)|Jim McCarthy] put it well in his book on software project management, <i>[https://www.amazon.com/dp/0735623198/|Dynamics of Software Development]</i>: "[https://www.youtube.com/watch?v=oY6BCHqEbyc|Beware of a guy in a room]."</p></li> <li><p><b>Branch names sync:</b> Unlike in Git, branch names in Fossil are not purely local labels. They sync along with everything else, so everyone sees the same set of branch names.

Fossil places a lot of emphasis on synchronizing everyone's work and on reporting on the state of the project and the work of its developers, so that everyone — especially the project leader — can maintain a better mental picture of what is happening, leading to better situational awareness. You can think about this difference in terms of [https://en.wikipedia.org/wiki/Feedback | feedback loop size], which we know from the mathematics of [https://en.wikipedia.org/wiki/Control_theory | control theory] to directly affect the speed at which any system can safely make changes. The larger the feedback loop, the slower the whole system must run in order to avoid loss of control. The same concept shows up in other contexts, such as in the [https://en.wikipedia.org/wiki/OODA_loop | OODA loop] concept originally developed to explain the success of the US F-86 Sabre fighter aircraft over the on-paper superior MiG-15, then later applied in other contexts, such as business process management. Committing your changes to private branches in order to delay a public push to the parent repo increases the size of your collaborators' control loops, either causing them to slow their work in order to safely react to your work, or to overcorrect in response to each change. Each DVCS can be used in the opposite style, but doing so works against their low-friction paths. <h4 id="scale">2.5.2 Scale</h4> The Linux kernel has a far bigger developer community than that of SQLite: there are thousands and thousands of contributors to Linux, most of whom do not know each others names. These thousands are responsible for producing roughly 89⨉ more code than is in SQLite. (10.7 [https://en.wikipedia.org/wiki/Source_lines_of_code|MLOC] vs. 0.12 MLOC according to [https://dwheeler.com/sloccount/|SLOCCount].) The Linux kernel and its development process were already uncommonly large back in 2005 when Git was designed, specifically to support the consequences of having such a large set of developers working on such a large code base. 95% of the code in SQLite comes from just four programmers, and 64% of it is from the lead developer alone. The SQLite developers know each other well and interact daily. Fossil was designed for this development model. We think you should ask yourself whether you have Linus Torvalds scale software configuration management problems or D. Richard Hipp scale problems when choosing your DVCS. An [https://en.wikipedia.org/wiki/Impact_wrench|automotive air impact wrench] running at 8000 RPM driving an M8 socket-cap bolt at 16 cm/s is not the best way to hang a picture on the living room wall. <h4 id="contrib">2.5.3 Accepting Contributions</h4> As of this writing, Git has received about 4.5⨉ as many commits as Fossil resulting in about 2.5⨉ as many lines of source code. The line count excludes tests and in-tree third-party dependencies. It does not exclude the default GUI for each, since it's integral for Fossil, so we count the size of <tt>gitk</tt> in this. It is obvious that Git is bigger in part because of its first-mover advantage, which resulted in a larger user community, which results in more contributions. But is that the <i>only</i> reason? We believe there are other relevant differences that also play into this which fall out of the "Linux vs. SQLite" framing: licensing, community structure, and how we react to [https://www.jonobacon.com/2012/07/25/building-strong-community-structural-integrity/|drive-by contributions]. In brief, it's harder to get a new feature into Fossil than into Git. A larger feature set is not necessarily a good thing. Git's command line interface is famously arcane. Masters of the arcane are able to do wizardly things, but only by studying their art deeply for years. This strikes us as a good thing only in cases where use of the tool itself is the primary point of that user's work. Almost no one uses a DVCS for its own sake; very few people get paid specifically in order to drive a DVCS. We use DVCSes as a tool to support some other effort, so we do not necessarily want the DVCS with the most features. We want a DVCS with easily internalized behavior so we can thoroughly master it despite spending only a small fraction of our working time thinking about the DVCS. We want to pick the tool up, use it quickly, and then set it aside in order to get back to our actual job as quickly as possible. Professional software developers in particular are prone to focusing on feature set sizes when choosing tools because this is sometimes a highly important consideration. They spend all day, every day, in their favorite text editors, and time they spend learning all of the arcana of their favorite programming languages is well-spent. Skills with these tools are direct productivity drivers, which in turn directly drives how much money a developer can make. (Or how much idle time they can afford to take, which amounts to the same thing.) But if you are a professional software developer, we want you to ask yourself a question: "How do I get paid more by mastering arcane features of my DVCS?" Unless you have a good answer to that, you probably do not want to be choosing a DVCS based on how many arcane features it has. The argument is similar for other types of users: if you are a hobbyist, how much time do you want to spend mastering your DVCS instead of on the hobby supported by use of that DVCS? There is some minimal set of features required to achieve the purposes that drive our selection of a DVCS, but there is a level beyond which more features only slow us down while we're learning the tool, since we must plow through documentation on features we're not likely to ever use. When the number of features grows to the point where people of normal motivation cannot spend the time to master them all, the tool becomes <i>less</i> productive to use. The core developers of the Fossil project achieve a balance between feature set size and ease of use by carefully choosing which users to give commit bits to, then in being choosy about which of the contributed feature branches to merge down to trunk. We say "no" to a lot of feature proposals. The end result is that Fossil more closely adheres to [https://en.wikipedia.org/wiki/Principle_of_least_astonishment|the principle of least astonishment] than Git does. <h4 id="branches">2.5.4 Individual Branches vs. The Entire Change History</h4> Both Fossil and Git store history as a directed acyclic graph (DAG) of changes, but Git tends to focus more on individual branches of the DAG, whereas Fossil puts more emphasis on the entire DAG. For example, the default behavior in Git is to only synchronize a single branch, whereas with Fossil the only sync option is to sync the entire DAG. Git commands, GitHub, and GitLab tend to show only a single branch at a time, whereas Fossil usually shows all parallel branches at once. Git has commands like "rebase" that help keep all relevant changes on a single branch, whereas Fossil encourages a style of many concurrent branches constantly springing into existence, undergoing active development in parallel for a few days or weeks, then merging back into the main line and disappearing. This difference in emphasis arises from the different purposes of the two systems. Git focuses on individual branches, because that is exactly what you want for a highly-distributed bazaar-style project such as Linux. Linus Torvalds does not want to see every check-in by every contributor to Linux, as such extreme visibility does not scale well. But Fossil was written for the cathedral-style SQLite project with just a handful of active committers. Seeing all changes on all branches all at once helps keep the whole team up-to-date with what everybody else is doing, resulting in a more tightly focused and cohesive implementation. <h3 id="checkouts">2.6 One vs. Many Check-outs per Repository</h3> Because Git commingles the repository data with the initial checkout of that repository, the default mode of operation in Git is to stick to that single work/repo tree, even when that's a shortsighted way of working. Fossil doesn't work that way. A Fossil repository is a SQLite database file which is normally stored outside the working checkout directory. You can [/help?cmd=open | open] a Fossil repository any number of times into any number of working directories. A common usage pattern is to have one working directory per active working branch, so that switching branches is done with a <tt>cd</tt> command rather than by checking out the branches successively in a single working directory. Fossil does allow you to switch branches within a working checkout directory, and this is also often done. It is simply that there is no inherent penalty to either choice in Fossil as there is in Git. The standard advice is to use a switch-in-place workflow in Fossil when the disturbance from switching branches is small, and to use multiple checkouts when you have long-lived working branches that are different enough that switching in place is disruptive. You can use Git in the Fossil style, either by manually symlinking the <tt>.git</tt> directory from one working directory to another or by use of the <tt>[https://git-scm.com/docs/git-worktree|git-worktree]</tt> feature. Nevertheless, Git's default tie between working directory and repository means the standard method for working with a Git repo is to have one working directory only. Most Git tutorials teach this style, so it is how most people learn to use Git. Because relatively few people use Git with multiple working directories per repository, there are [https://duckduckgo.com/?q=git+worktree+problem | several known problems] with that way of working, problems which don't happen in Fossil because of the clear separation between repository and working directory. This distinction matters because switching branches inside a single working directory loses local context on each switch. For instance, in any software project where the runnable program must be built from source files, you invalidate build objects on each switch, artificially increasing the time required to switch versions. Most obviously, this affects software written in statically-compiled programming languages such as C, Java, and Haskell, but it can even affect programs written in dynamic languages like JavaScript. A typical [https://en.wikipedia.org/wiki/Single-page_application | SPA] build process involves several passes: [http://browserify.org/ | Browserify] to convert [https://nodejs.org/ | Node] packages so they'll run in a web browser, [https://sass-lang.com | SASS] to CSS translation, transpilation of [https://www.typescriptlang.org | Typescript] to JavaScript, [https://github.com/mishoo/UglifyJS | uglification], etc. Once all that processing work is done for a given input file in a given working directory, why re-do that work just to switch versions? If most of the files that differ between versions don't change very often, you can save substantial time by switching branches with <tt>cd</tt> rather than swapping versions in-place within a working checkout directory. For another example, you might have an active long-running test grinding away in a working directory, then get a call from a customer requiring that you switch to a stable branch to answer questions in terms of the version that customer is running. You don't want to stop the test in order to switch your lone working directory to the stable branch. Disk space is cheap. Having several working directories, each with its own local state, makes switching versions cheap and fast. Plus, <tt>cd</tt> is faster to type than <tt>git checkout</tt> or <tt>fossil update</tt>. <h3 id="history">2.7 What you should have done vs. What you actually did</h3> Git puts a lot of emphasis on maintaining a "clean" check-in history. Extraneous and experimental branches by individual developers often never make it into the main repository. And branches are often rebased before being pushed, to make it appear as if development had been linear. Git strives to record what the development of a project should have looked like had there been no mistakes. Fossil, in contrast, puts more emphasis on recording exactly what happened, including all of the messy errors, dead-ends, experimental branches, and so forth. One might argue that this makes the history of a Fossil project "messy," but another point of view is that this makes the history "accurate." In actual practice, the superior reporting tools available in Fossil mean that the added "mess" is not a factor. Like Git, Fossil has an [/help?cmd=amend|amend command] for modifying prior commits, but unlike in Git, this works not by replacing data in the repository, but by adding a correction record to the repository that affects how later Fossil operations present the corrected data. The old information is still there in the repository, it is just overridden from the amendment point forward. For extreme situations, Fossil adds the [/doc/trunk/www/shunning.wiki|shunning mechanism], but it has strict limitations that prevent global history rewrites. One commentator characterized Git as recording history according to the victors, whereas Fossil records history as it actually happened. We go into more detail on this topic in a separate article, [./rebaseharm.md | Rebase Considered Harmful]. <h3 id="testing">2.8 Test Before Commit</h3> One of the things that falls out of Git's default separation of commit from push is that there are several Git sub-commands that jump straight to the commit step before a change could possibly be tested. Fossil, by contrast, makes the equivalent change to the local working check-out only, requiring a separate check-in step to commit the change. This design difference falls naturally out of Fossil's default-enabled autosync feature. The prime example in Git is rebasing: the change happens to the local repository immediately if successful, even though you haven't tested the change yet. It's possible to argue for such a design in a tool like Git which doesn't automatically push the change up to its parent, because you can still test the change before pushing local changes to the parent repo, but in the meantime you've made a durable change to your local Git repository's blockchain. You must do something drastic like <tt>git reset --hard</tt> to revert that rebase if it causes a problem. If you push your rebased local repo up to the parent without testing first, you've now committed the error on a public branch, effectively a violation of [https://www.atlassian.com/git/tutorials/merging-vs-rebasing#the-golden-rule-of-rebasing | the golden rule of rebasing]. Lesser examples are the Git <tt>merge</tt>, <tt>cherry-pick</tt>, and <tt>revert</tt> commands, all of which apply work from one branch onto another, and all of which do their work immediately without giving you an opportunity to test the change first locally unless you give the <tt>--no-commit</tt> option. Fossil cannot sensibly work that way because of its default-enabled autosync feature. Instead of jumping straight to the commit step, Fossil applies the proposed merge to the local working directory only, requiring a separate check-in step before the change is committed to the repository blockchain. This gives you a chance to test the change first, either manually or by running your software's automatic tests. (Ideally, both!) Another difference is that because Fossil requires an explicit commit for a merge, it makes you give an explicit commit <i>message</i> for each merge, whereas Git writes that commit message itself by default unless you give the optional <tt>--edit</tt> flag to override it. We don't look at this difference as a workaround in Fossil for autosync, but instead as a test-first philosophical difference. When every commit is pushed to the parent repo by default, it encourages a working style in which every commit is tested first. We think this is an inherently good thing. Incidentally, this is a good example of Git's messy command design. These three commands: <pre> $ git merge HASH $ git cherry-pick HASH $ git revert HASH </pre> ...are all the same command in Fossil: <pre> $ fossil merge HASH $ fossil merge --cherrypick HASH $ fossil merge --backout HASH </pre> If you think about it, they're all the same function: apply work done on one branch to another. All that changes between these commands is how much work gets applied — just one check-in or a whole branch — and the merge direction. This is the sort of thing we mean when we point out that Fossil's command interface is simpler than Git's: there are fewer concepts to keep track of in your mental model of Fossil's internal operation. Fossil's implementation of the feature is also simpler to describe. The brief online help for <tt>[/help?cmd=merge | fossil merge]</tt> is currently 41 lines long, to which you want to add the 600 lines of [./branching.wiki | the branching document]. The equivalent documentation in Git is the aggregation of the man pages for the above three commands, which is over 1000 lines, much of it mutually redundant. (e.g. Git's <tt>--edit</tt> and <tt>--no-commit</tt> options get described three times, each time differently.) Fossil's documentation is not only more concise, it gives a nice split of brief online help and full online documentation. <h3 id="hash">2.9 Hash Algorithm: SHA-3 vs SHA-2 vs SHA-1</h3> Fossil started out using 160-bit SHA-1 hashes to identify check-ins, just as in Git. That changed in early 2017 when news of the [https://shattered.io/|SHAttered attack] broke, demonstrating that SHA-1 collisions were now practical to create. Two weeks later, the creator of Fossil delivered a new release allowing a clean migration to [https://en.wikipedia.org/wiki/SHA-3|256-bit SHA-3] with [./hashpolicy.wiki|full backwards compatibility] to old SHA-1 based repositories. In October 2019, after the last of the major binary package repos offering Fossil upgraded to Fossil 2.<i>x</i>, we switched the default hash mode so that from Fossil 2.10 forward, the conversion to SHA-3 is fully automatic. This not only solves the SHAttered problem, it should prevent a reoccurrence of similar problems for the foreseeable future. Meanwhile, the Git community took until August 2018 to publish [https://git-scm.com/docs/hash-function-transition/|their first plan] for solving the same problem by moving to SHA-256, a variant of the [https://en.wikipedia.org/wiki/SHA-2 | older SHA-2 algorithm]. As of this writing in February 2020, that plan hasn't been implemented, as far as this author is aware, but there is now [https://lwn.net/ml/git/20200113124729.3684846-1-sandals@crustytoothpaste.net/ | a competing SHA-256 based plan] which requires complete repository conversion from SHA-1 to SHA-256, breaking all public hashes in the repo. One way to characterize such a massive upheaval in Git terms is a whole-project rebase, which violates [https://blog.axosoft.com/golden-rule-of-rebasing-in-git/ | Git's own Golden Rule of Rebasing]. Regardless of the eventual implementation details, we fully expect Git to move off SHA-1 eventually and for the changes to take years more to percolate through the community. Almost three years after Fossil solved this problem, the [https://sha-mbles.github.io/ | SHAmbles attack] was published, further weakening the case for continuing to use SHA-1. The practical impact of attacks like SHAttered and SHAmbles on the Git and Fossil blockchains isn't clear, but you want to have your repositories moved over to a stronger hash algorithm before someone figures out how to make use of the weaknesses in the old one. Fossil has had this covered for years now, so that the solution is now almost universally deployed. <hr/> <h3>Asides and Digressions</h3> <i><small><ol> <li><p>[./mirrorlimitations.md|Many things are lost] in making a Git mirror of a Fossil repo due to limitations of Git relative to Fossil. GitHub adds some of these missing features to stock Git, but because they're not part of Git proper, [./mirrortogithub.md|exporting a Fossil repository to GitHub] will still not include them; Fossil tickets do not become GitHub issues, for example. <li><p>The <tt>fossil-scm.org</tt> web site is actually hosted in several parts, so that it is not strictly true that "everything" on it is in the self-hosting Fossil project repo. The web forum is hosted as [https://fossil-scm.org/forum/|a separate Fossil repo] from the [https://fossil-scm.org/fossil/|main Fossil self-hosting repo] for administration reasons, and the Download page content isn't normally synchronized with a "<tt>fossil clone</tt>" command unless you add the "-u" option. (See "[./aboutdownload.wiki|How the Download Page Works]" for details.) There may also be some purely static elements of the web site served via D. Richard Hipp's own lightweight web server, <tt>[https://sqlite.org/docsrc/doc/trunk/misc/althttpd.md|althttpd]</tt>, which is configured as a front end to Fossil running in CGI mode on these sites. <li><p>That estimate is based on pricing at Digital Ocean in mid-2019: Fossil will run just fine on the smallest instance they offer, at US $5/month, but the closest match to GitLab's minimum requirements among Digital Ocean's offerings currently costs $40/month. <li><p>This means you can give up waiting for Fossil to be ported to the PDP-11, but we remain hopeful that someone may eventually port it to [https://en.wikipedia.org/wiki/Z/OS|z/OS]. <li><p>"Why is there all this Tcl in and around Fossil?" you may ask. It is because D. Richard Hipp is a long-time Tcl user and contributor. SQLite started out as an embedded database for Tcl specifically. ([https://sqlite.org/tclsqlite.html | [Reference]]) When he then created Fossil to manage the development of SQLite, it was natural for him to use Tcl-based tools for its scripting, build system, test system, etc. It came full circle in 2011 when [https://www.reddit.com/r/programming/comments/fwrx5/tcl_and_tk_move_away_from_cvs_to_fossil/ | the Tcl and Tk projects moved from CVS to Fossil]. <li><p>A minority of the pieces of the Git core software suite are written in other languages, primarily Perl, Python, and Tcl. (e.g. <tt>git-send-mail</tt>, <tt>git-p4</tt>, and <tt>gitk</tt>, respectively.) Although these interpreters are quite portable, they aren't installed by default everywhere, and on some platforms you can't count on them at all. (Not just Windows, but also the BSDs and many other non-Linux platforms.) This expands the dependency footprint of Git considerably. It is why the current Git for Windows distribution is 44.7 MiB but the current <tt>fossil.exe</tt> zip file for Windows is 2.24 MiB. Fossil is much smaller despite using a roughly similar amount of high-level scripting code because its interpreters are compact and built into Fossil itself. <li><p>Both Fossil and Git support [https://en.wikipedia.org/wiki/Patch_(Unix)|<tt>patch(1)</tt> files], a common way to allow drive-by contributions, but it's a lossy contribution path for both systems. Unlike Git PRs and Fossil bundles, patch files collapse multiple checkins together, they don't include check-in comments, and they cannot encode changes made above the individual file content layer: you lose branching decisions, tag changes, file renames, and more when using patch files.</p></li> </ol></i></small> |

The prompt shows the branch, version, and time stamp for the current checkout, and the prompt changes colors from blue to red when there are uncommitted changes. To try out this script, simply download it from the link above, then type: <blockquote><pre> . fossil_prompt.sh </pre></blockquote> For a permanent installation, you can graft the code into your <tt>.bashrc</tt> file in your home directory. The code is very simple (only 32 non-comment lines, as of this writing) and hence easy to customized. |

In other words, this document tries to describe the differences in how Fossil works from the perspective of Git users. ## Help Improve This Document If you have a lot of prior Git experience, and you are new to Fossil and are struggling with some concepts, please ask for help on the [Fossil Forum][1]. The people who write this document are intimately familiar with Fossil and less familiar with Git. It is difficult for us to anticipate the perspective of people who are initimately familiar with Git and less familiar with Fossil. Asking questions on the Forum will help us to improve the document. [1]: https://fossil-scm.org/forum Specific suggestions on how to improve this document are also welcomed, of course. ## Repositories And Checkouts Are Distinct A repository and a check-out are distinct concepts in Fossil, whereas the two are often conflated with Git. A repository is a database in which the entire history of a project is stored. A check-out is a directory hierarchy that contains a snapshot of your project that you are currently working on. See [detailed definitions][2] for more information. With Git, the repository and check-out are closely related - the repository is the contents of the "`.git`" subdirectory at the root of your check-out. But with Fossil, the repository and the check-out are completely separate. A Fossil repository can reside in the same directory hierarchy with the check-out as with Git, but it is more common to put the repository in a separate directory. [2]: ./whyusefossil.wiki#definitions Fossil repositories are a single file, rather than being a directory hierarchy as with the "`.git`" folder in Git. The repository file can be named anything you want, but it is best to use the "`.fossil`" suffix. Many people choose to gather all of their Fossil repositories in a single directory on their machine, such as "`~/Fossils`" or "`C:\Fossils`". This can help humans to keep their repositories organized, but Fossil itself doesn't really care. Because Fossil cleanly separates the repository from the check-out, it is routine to have multiple check-outs from the same repository. Each check-out can be on a separate branch, or on the same branch. Each check-out operates independently of the others. Each Fossil check-out contains a file (usually named "`.fslckout`" on unix or "`_FOSSIL_`" on Windows) that keeps track of the status of that particular check-out and keeps a pointer to the repository. If you move or rename the repository file, the check-outs won't be able to find it and will complain. But you can freely move check-outs around without causing any problems. ## There Is No Staging Area Fossil omits the "Git index" or "staging area" concept. When you type "`fossil commit`" _all_ changes in your check-out are committed, automatically. There is no need for the "-a" option as with Git. If you only want to commit just some of the changes, you can list the names of the files you want to commit as arguments, like this: fossil commit src/main.c doc/readme.md ## Create Branches After-The-Fact Fossil perfers that you create new branches when you commit using the "`--branch` _BRANCH-NAME_" command-line option. For example: fossil commit --branch my-new-branch It is not necessary to create branches ahead of time, as in Git, though that is allowed using the "`fossil branch new`" command, if you prefer. Fossil also allows you to move a check-in to a different branch *after* you commit it, using the "`fossil amend`" command. For example: fossil amend current --branch my-new-branch ## Autosync Fossil has a feature called "[autosync][5]". Autosync defaults on. When autosync is enabled, Fossil automatically pushes your changes to the remote server whenever you "`fossil commit`". It also automatically pulls all remote changes down to your local repository before you "`fossil update`". [5]: ./concepts.wiki#workflow Autosync provides most of the advantages of a centralized version control system while retaining the advantages of distributed version control. Your work stays synced up with your coworkers at all times. If your local machine dies catastrophically, you haven't lost any (committed) work. But you can still work and commit while off network, with changes resyncing automatically when you get back on-line. ## Syncing Is All-Or-Nothing Fossil does not support the concept of syncing, pushing, or pulling individual branches. When you sync/push/pull in Fossil, you sync/push/pull everything - all branches, all wiki, all tickets, all forum posts, all tags, all technotes - everything. ## The Main Branch Is Called "`trunk`", not "`master`" In Fossil, the traditional name and the default name for the main branch is "`trunk`". The "`trunk`" branch in Fossil corresponds to the "`master`" branch in Git. These naming conventions are so embedded in each system, that the "trunk" branch name is automatically translated to "master" when a [Fossil repo is mirrored to GitHub][6]. [6]: ./mirrortogithub.md ## The "`fossil status`" Command Does Not Show Unmanaged Files The "`fossil status`" command shows you what files in your check-out have been edited and scheduled for adding or removing at the next commit. But unlike "`git status`", the "`fossil status`" command does not warn you about unmanaged files in your local check-out. There is a separate "`fossil extras`" command for that. ## There Is No Rebase Fossil does not support rebase. This is a [deliberate design decision][3] that has been thoroughly, carefully, and throughtfully discussed, many times. If you are fond of rebase, you should read the [Rebase Considered Harmful][3] document carefully before expressing your views. [3]: ./rebaseharm.md ## Branch and Tag Names Fossil has no special restrictions on the names of tags and branches, though you might want to keep [Git's tag and branch name restrictions][4] in mind if you plan on mirroring your Fossil repository to GitHub. [4]: https://git-scm.com/docs/git-check-ref-format Fossil does not require tag and branch names to be unique. It is common, for example, to put a "`release`" tag on every release for a Fossil-hosted project. ## Only One "origin" At A Time A Fossil repository only keeps track of one "origin" server at a time. If you specify a new "origin" it forgets the previous one. Use the "`fossil remote`" command to see or change the "origin". Fossil uses a very different sync protocol than Git, so it isn't as important for Fossil to keep track of multiple origins as it is with Git. So only having a single origin has never been a big enough problem in Fossil that somebody felt the need to extend it. Maybe we will add multiple origin support to Fossil someday. Patches are welcomed if you want to have a go at it. ## Cherry-pick Is An Option To The "merge" Command In Git, "`git cherry-pick`" is a separate command. In Fossil, "`fossil merge --cherrypick`" is an option on the merge command. Otherwise, they work mostly the same. Except, the Fossil file format remembers cherrypicks and actually shows them as dashed lines on the graphical DAG display, whereas there is no provision for recording cherry-picks in the Git file format, so you have to talk about the cherry-pick in the commit comment if you want to remember it. ## The "`fossil mv`" and "`fossil rm`" Commands Do Not Actually Rename Or Delete The Files (by default) By default, the "`fossil mv`" and "`fossil rm`" commands work like they do in CVS in that they schedule the changes for the next commit, but do not actually rename or delete the files in your check-out. You can to add the "--hard" option to also changes the files in your check-out. If you run fossil setting --global mv-rm-files 1 it makes a notation in your per-user "~/.fossil" settings file so that the "--hard" behavior becomes the new default. |

For example, `*` is a glob that matches any name at all and `Readme.txt` is a glob that matches exactly one file. A glob should not be confused with a [regular expression][regexp] (RE), even though they use some of the same special characters for similar purposes, because [they are not fully compatible][greinc] pattern matching languages. Fossil uses globs when matching file names with the settings described in this document, not REs. [glob]: https://en.wikipedia.org/wiki/Glob_(programming) [greinc]: https://unix.stackexchange.com/a/57958/138 [regexp]: https://en.wikipedia.org/wiki/Regular_expression These settings hold one or more file glob patterns to cause Fossil to give matching named files special treatment. Glob patterns are also accepted in options to certain commands and as query parameters to certain Fossil UI web pages. Where Fossil also accepts globs in commands, this handling may interact with your OS’s command shell or its C runtime system, because they may have their own glob pattern handling. We will detail such interactions below. ## Syntax Where Fossil accepts glob patterns, it will usually accept a *list* of such patterns, each individual pattern separated from the others by white space or commas. If a glob must contain white spaces or commas, it can be quoted with either single or double quotation marks. A list is said to match if any one glob in the list matches. A glob pattern matches a given file name if it successfully consumes and matches the *entire* name. Partial matches are failed matches. Most characters in a glob pattern consume a single character of the file name and must match it exactly. For instance, “a†in a glob simply matches the letter “a†in the file name unless it is inside a special character sequence. Other characters have special meaning, and they may include otherwise normal characters to give them special meaning: :Pattern |:Effect --------------------------------------------------------------------- `*` | Matches any sequence of zero or more characters `?` | Matches exactly one character `[...]` | Matches one character from the enclosed list of characters `[^...]` | Matches one character *not* in the enclosed list Note that unlike [POSIX globs][pg], these special characters and sequences are allowed to match `/` directory separators as well as the initial `.` in the name of a hidden file or directory. This is because Fossil file names are stored as complete path names. The distinction between file name and directory name is “below†Fossil in this sense. [pg]: https://pubs.opengroup.org/onlinepubs/9699919799/utilities/V3_chap02.html#tag_18_13 The bracket expresssions above require some additional explanation: * A range of characters may be specified with `-`, so `[a-f]` matches exactly the same characters as `[abcdef]`. Ranges reflect Unicode code points without any locale-specific collation sequence. Therefore, this particular sequence never matches the Unicode pre-composed character `é`, for example. (U+00E9) * This dependence on character/code point ordering may have other effects to surprise you. For example, the glob `[A-z]` not only matches upper and lowercase ASCII letters, it also matches several punctuation characters placed between `Z` and `a` in both ASCII and Unicode: `[`, `\`, `]`, `^`, `_`, and <tt>\`</tt>. * You may include a literal `-` in a list by placing it last, just before the `]`. * You may include a literal `]` in a list by making the first character after the `[` or `[^`. At any other place, `]` ends the list. * You may include a literal `^` in a list by placing it anywhere except after the opening `[`. * Beware that a range must be specified from low value to high value: `[z-a]` does not match any character at all, preventing the entire glob from matching. Some examples of character lists: :Pattern |:Effect --------------------------------------------------------------------- `[a-d]` | Matches any one of `a`, `b`, `c`, or `d` but not `ä` `[^a-d]` | Matches exactly one character other than `a`, `b`, `c`, or `d` `[0-9a-fA-F]` | Matches exactly one hexadecimal digit `[a-]` | Matches either `a` or `-` `[][]` | Matches either `]` or `[` `[^]]` | Matches exactly one character other than `]` `[]^]` | Matches either `]` or `^` `[^-]` | Matches exactly one character other than `-` White space means the specific ASCII characters TAB, LF, VT, FF, CR, and SPACE. Note that this does not include any of the many additional spacing characters available in Unicode such as U+00A0, NO-BREAK SPACE. Because both LF and CR are white space and leading and trailing spaces are stripped from each glob in a list, a list of globs may be broken into lines between globs when the list is stored in a file, as for a versioned setting. Note that 'single quotes' and "double quotes" are the ASCII straight quote characters, not any of the other quotation marks provided in Unicode and specifically not the "curly" quotes preferred by typesetters and word processors. ## File Names to Match Before it is compared to a glob pattern, each file name is transformed to a canonical form: * all directory separators are changed to `/` * redundant slashes are removed * all `.` path components are removed * all `..` path components are resolved (There are additional details we are ignoring here, but they cover rare edge cases and follow the principle of least surprise.) The glob must match the *entire* canonical file name to be considered a match. The goal is to have a name that is the simplest possible for each particular file, and that will be the same regardless of the platform you run Fossil on. This is important when you have a repository cloned from multiple platforms and have globs in versioned settings: you want those settings to be interpreted the same way everywhere. Beware, however, that all glob matching in Fossil is case sensitive regardless of host platform and file system. This will not be a surprise on POSIX platforms where file names are usually treated case sensitively. However, most Windows file systems are case preserving but case insensitive. That is, on Windows, the names `ReadMe` and `README` are usually names of the same file. The same is true in other cases, such as by default on macOS file systems and in the file system drivers for Windows file systems running on non-Windows systems. (e.g. exfat on Linux.) Therefore, write your Fossil glob patterns to match the name of the file as checked into the repository. Some example cases: :Pattern |:Effect -------------------------------------------------------------------------------- `README` | Matches only a file named `README` in the root of the tree. It does not match a file named `src/README` because it does not include any characters that consume (and match) the `src/` part. `*/README` | Matches `src/README`. Unlike Unix file globs, it also matches `src/library/README`. However it does not match the file `README` in the root of the tree. `*README` | Matches `src/README` as well as the file `README` in the root of the tree as well as `foo/bar/README` or any other file named `README` in the tree. However, it also matches `A-DIFFERENT-README` and `src/DO-NOT-README`, or any other file whose name ends with `README`. `src/README` | Matches `src\README` on Windows because all directory separators are rewritten as `/` in the canonical name before the glob is matched. This makes it much easier to write globs that work on both Unix and Windows. `*.[ch]` | Matches every C source or header file in the tree at the root or at any depth. Again, this is (deliberately) different from Unix file globs and Windows wild cards. ## Where Globs are Used ### Settings that are Globs These settings are all lists of glob patterns: :Setting |:Description -------------------------------------------------------------------------------- `binary-glob` | Files that should be treated as binary files for committing and merging purposes `clean-glob` | Files that the [`clean`][] command will delete without prompting or allowing undo `crlf-glob` | Files in which it is okay to have `CR`, `CR`+`LF` or mixed line endings. Set to "`*`" to disable CR+LF checking `crnl-glob` | Alias for the `crlf-glob` setting `encoding-glob` | Files that the [`commit`][] command will ignore when issuing warnings about text files that may use another encoding than ASCII or UTF-8. Set to "`*`" to disable encoding checking `ignore-glob` | Files that the [`add`][], [`addremove`][], [`clean`][], and [`extras`][] commands will ignore `keep-glob` | Files that the [`clean`][] command will keep All may be [versioned, local, or global](settings.wiki). Use `fossil settings` to manage local and global settings, or a file in the repository's `.fossil-settings/` folder at the root of the tree named for each for versioned setting. Using versioned settings for these not only has the advantage that they are tracked in the repository just like the rest of your project, but you can more easily keep longer lists of more complicated glob patterns than would be practical in either local or global settings. The `ignore-glob` is an example of one setting that frequently grows to be an elaborate list of files that should be ignored by most commands. This is especially true when one (or more) IDEs are used in a project because each IDE has its own ideas of how and where to cache information that speeds up its browsing and building tasks but which need not be preserved in your project's history. ### Commands that Refer to Globs Many of the commands that respect the settings containing globs have options to override some or all of the settings. These options are usually named to correspond to the setting they override, such as `--ignore` to override the `ignore-glob` setting. These commands are: * [`add`][] * [`addremove`][] * [`changes`][] * [`clean`][] * [`commit`][] * [`extras`][] * [`merge`][] * [`settings`][] * [`status`][] * [`touch`][] * [`unset`][] The commands [`tarball`][] and [`zip`][] produce compressed archives of a specific checkin. They may be further restricted by options that specify glob patterns that name files to include or exclude rather than archiving the entire checkin. The commands [`http`][], [`cgi`][], [`server`][], and [`ui`][] that implement or support with web servers provide a mechanism to name some files to serve with static content where a list of glob patterns specifies what content may be served. [`add`]: /help?cmd=add [`addremove`]: /help?cmd=addremove [`changes`]: /help?cmd=changes [`clean`]: /help?cmd=clean [`commit`]: /help?cmd=commit [`extras`]: /help?cmd=extras [`merge`]: /help?cmd=merge [`settings`]: /help?cmd=settings [`status`]: /help?cmd=status [`touch`]: /help?cmd=touch [`unset`]: /help?cmd=unset [`tarball`]: /help?cmd=tarball [`zip`]: /help?cmd=zip [`http`]: /help?cmd=http [`cgi`]: /help?cmd=cgi [`server`]: /help?cmd=server [`ui`]: /help?cmd=ui ### Web Pages that Refer to Globs The [`/timeline`][] page supports the query parameter `chng=GLOBLIST` that names a list of glob patterns defining which files to focus the timeline on. It also has the query parameters `t=TAG` and `r=TAG` that names a tag to focus on, which can be configured with `ms=STYLE` to use a glob pattern to match tag names instead of the default exact match or a couple of other comparison styles. The pages [`/tarball`][] and [`/zip`][] generate compressed archives of a specific checkin. They may be further restricted by query parameters that specify glob patterns that name files to include or exclude rather than taking the entire checkin. [`/timeline`]: /help?cmd=/timeline [`/tarball`]: /help?cmd=/tarball [`/zip`]: /help?cmd=/zip ## Platform Quirks Fossil glob patterns are based on the glob pattern feature of POSIX shells. Fossil glob patterns also have a quoting mechanism, discussed above. Because other parts of your operating system may interpret glob patterns and quotes separately from Fossil, it is often difficult to give glob patterns correctly to Fossil on the command line. Quotes and special characters in glob patterns are likely to be interpreted when given as part of a `fossil` command, causing unexpected behavior. These problems do not affect [versioned settings files](settings.wiki) or Admin → Settings in Fossil UI. Consequently, it is better to set long-term `*-glob` settings via these methods than to use `fossil settings` commands. That advice does not help you when you are giving one-off glob patterns in `fossil` commands. The remainder of this section gives remedies and workarounds for these problems. ### <a name="posix"></a>POSIX Systems If you are using Fossil on a system with a POSIX-compatible shell — Linux, macOS, the BSDs, Unix, Cygwin, WSL etc. — the shell may expand the glob patterns before passing the result to the `fossil` executable. Sometimes this is exactly what you want. Consider this command for example: $ fossil add RE* If you give that command in a directory containing `README.txt` and `RELEASE-NOTES.txt`, the shell will expand the command to: $ fossil add README.txt RELEASE-NOTES.txt …which is compatible with the `fossil add` command's argument list, which allows multiple files. Now consider what happens instead if you say: $ fossil add --ignore RE* src/*.c This *does not* do what you want because the shell will expand both `RE*` and `src/*.c`, causing one of the two files matching the `RE*` glob pattern to be ignored and the other to be added to the repository. You need to say this in that case: $ fossil add --ignore 'RE*' src/*.c The single quotes force a POSIX shell to pass the `RE*` glob pattern through to Fossil untouched, which will do its own glob pattern matching. There are other methods of quoting a glob pattern or escaping its special characters; see your shell's manual. Beware that Fossil's `--ignore` option does not override explicit file mentions: $ fossil add --ignore 'REALLY SECRET STUFF.txt' RE* You might think that would add everything beginning with `RE` *except* for `REALLY SECRET STUFF.txt`, but when a file is both given explicitly to Fossil and also matches an ignore rule, Fossil asks what you want to do with it in the default case; and it does not even ask if you gave the `-f` or `--force` option along with `--ignore`. The spaces in the ignored file name above bring us to another point: such file names must be quoted in Fossil glob patterns, lest Fossil interpret it as multiple glob patterns, but the shell interprets quotation marks itself. One way to fix both this and the previous problem is: $ fossil add --ignore "'REALLY SECRET STUFF.txt'" READ* The nested quotation marks cause the inner set to be passed through to Fossil, and the more specific glob pattern at the end — that is, `READ*` vs `RE*` — avoids a conflict between explicitly-listed files and `--ignore` rules in the `fossil add` command. Another solution would be to use shell escaping instead of nested quoting: $ fossil add --ignore "\"REALLY SECRET STUFF.txt\"" READ* It bears repeating that the two glob patterns here are not interpreted the same way when running this command from a *subdirectory* of the top checkout directory as when running it at the top of the checkout tree. If these files were in a subdirectory of the checkout tree called `doc` and that was your current working directory, the command would have to be: $ fossil add --ignore "'doc/REALLY SECRET STUFF.txt'" READ* instead. The Fossil glob pattern still needs the `doc/` prefix because Fossil always interprets glob patterns from the base of the checkout directory, not from the current working directory as POSIX shells do. When in doubt, use `fossil status` after running commands like the above to make sure the right set of files were scheduled for insertion into the repository before checking the changes in. You never want to accidentally check something like a password, an API key, or the private half of a public cryptographic key into Fossil repository that can be read by people who should not have such secrets. ### <a name="windows"></a>Windows Before we get into Windows-specific details here, beware that this section does not apply to the several Microsoft Windows extensions that provide POSIX semantics to Windows, for which you want to use the advice in [the POSIX section above](#posix) instead: * the ancient and rarely-used [Microsoft POSIX subsystem][mps]; * its now-discontinued replacement feature, [Services for Unix][sfu]; or * their modern replacement, the [Windows Subsystem for Linux][wsl] [mps]: https://en.wikipedia.org/wiki/Microsoft_POSIX_subsystem [sfu]: https://en.wikipedia.org/wiki/Windows_Services_for_UNIX [wsl]: https://en.wikipedia.org/wiki/Windows_Subsystem_for_Linux (The latter is sometimes incorrectly called "Bash on Windows" or "Ubuntu on Windows," but the feature provides much more than just Bash or Ubuntu for Windows.) Neither standard Windows command shell — `cmd.exe` or PowerShell — expands glob patterns the way POSIX shells do. Windows command shells rely on the command itself to do the glob pattern expansion. The way this works depends on several factors: * the version of Windows you are using * which OS upgrades have been applied to it * the compiler that built your Fossil executable * whether you are running the command interactively * whether the command is built against a runtime system that does this at all * whether the Fossil command is being run from a file named `*.BAT` vs being named `*.CMD` Usually (but not always!) the C runtime library that your `fossil.exe` executable is built against does this glob expansion on Windows so the program proper does not have to. This may then interact with the way the Windows command shell you’re using handles argument quoting. Because of these differences, it is common to find perfectly valid Fossil command examples that were written and tested on a POSIX system which then fail when tried on Windows. The most common problem is figuring out how to get a glob pattern passed on the command line into `fossil.exe` without it being expanded by the C runtime library that your particular Fossil executable is linked to, which tries to act like [the POSIX systems described above](#posix). Windows is not strongly governed by POSIX, so it has not historically hewed closely to its strictures. For example, consider how you would set `crlf-glob` to `*` in order to get normal Windows text files with CR+LF line endings past Fossil's "looks like a binary file" check. The naïve approach will not work: C:\...> fossil setting crlf-glob * The C runtime library will expand that to the list of all files in the current directory, which will probably cause a Fossil error because Fossil expects either nothing or option flags after the setting's new value, not a list of file names. (To be fair, the same thing will happen on POSIX systems, only at the shell level, before `.../bin/fossil` even gets run by the shell.) Let's try again: C:\...> fossil setting crlf-glob '*' Quoting the argument like that will work reliably on POSIX, but it may or may not work on Windows. If your Windows command shell interprets the quotes, it means `fossil.exe` will see only the bare `*` so the C runtime library it is linked to will likely expand the list of files in the current directory before the `setting` command gets a chance to parse the command line arguments, causing the same failure as above. This alternative only works if you’re using a Windows command shell that passes the quotes through to the executable *and* you have linked Fossil to a C runtime library that interprets the quotes properly itself, resulting in a bare `*` getting clear down to Fossil’s `setting` command parser. An approach that *will* work reliably is: C:\...> echo * | fossil setting crlf-glob --args - This works because the built-in Windows command `echo` does not expand its arguments, and the `--args -` option makes Fossil read further command arguments from its standard input, which is connected to the output of `echo` by the pipe. (`-` is a common Unix convention meaning "standard input," which Fossil obeys.) A [batch script][fng.cmd] to automate this trick was posted on the now-inactive Fossil Mailing List. [fng.cmd]: https://www.mail-archive.com/fossil-users@lists.fossil-scm.org/msg25099.html (Ironically, this method will *not* work on POSIX systems because it is not up to the command to expand globs. The shell will expand the `*` in the `echo` command, so the list of file names will be passed to the `fossil` standard input, just as with the first example above!) Another (usually) correct approach which will work on both Windows and POSIX systems: C:\...> fossil setting crlf-glob *, This works because the trailing comma prevents the glob pattern from matching any files, unless you happen to have files named with a trailing comma in the current directory. If the pattern matches no files, it is passed into Fossil's `main()` function as-is by the C runtime system. Since Fossil uses commas to separate multiple glob patterns, this means "all files from the root of the Fossil checkout directory downward and nothing else," which is of course equivalent to "all managed files in this repository," our original goal. ## Experimenting To preview the effects of command line glob pattern expansion for various glob patterns (unquoted, quoted, comma-terminated), for any combination of command shell, OS, C run time, and Fossil version, preceed the command you want to test with [`test-echo`][] like so: $ fossil test-echo setting crlf-glob "*" C:\> echo * | fossil test-echo setting crlf-glob --args - The [`test-glob`][] command is also handy to test if a string matches a glob pattern. [`test-echo`]: /help?cmd=test-echo [`test-glob`]: /help?cmd=test-glob ## Converting `.gitignore` to `ignore-glob` Many other version control systems handle the specific case of ignoring certain files differently from Fossil: they have you create individual "ignore" files in each folder, which specify things ignored in that folder and below. Usually some form of glob patterns are used in those files, but the details differ from Fossil. In many simple cases, you can just store a top level "ignore" file in `.fossil-settings/ignore-glob`. But as usual, there will be lots of edge cases. [Git has a rich collection of ignore files][gitignore] which accumulate rules that affect the current command. There are global files, per-user files, per workspace unmanaged files, and fully version controlled files. Some of the files used have no set name, but are called out in configuration files. [gitignore]: https://git-scm.com/docs/gitignore In contrast, Fossil has a global setting and a local setting, but the local setting overrides the global rather than extending it. Similarly, a Fossil command's `--ignore` option replaces the `ignore-glob` setting rather than extending it. With that in mind, translating a `.gitignore` file into `.fossil-settings/ignore-glob` may be possible in many cases. Here are some of features of `.gitignore` and comments on how they relate to Fossil: * "A blank line matches no files...": same in Fossil. * "A line starting with # serves as a comment....": not in Fossil. * "Trailing spaces are ignored unless they are quoted..." is similar in Fossil. All whitespace before and after a glob is trimmed in Fossil unless quoted with single or double quotes. Git uses backslash quoting instead, which Fossil does not. * "An optional prefix "!" which negates the pattern...": not in Fossil. * Git's globs are relative to the location of the `.gitignore` file: Fossil's globs are relative to the root of the workspace. * Git's globs and Fossil's globs treat directory separators differently. Git includes a notation for zero or more directories that is not needed in Fossil. ### Example In a project with source and documentation: work +-- doc +-- src The file `doc/.gitignore` might contain: # Finished documents by pandoc via LaTeX *.pdf # Intermediate files *.tex *.toc *.log *.out *.tmp Entries in `.fossil-settings/ignore-glob` with similar effect, also limited to the `doc` folder: doc/*.pdf doc/*.tex, doc/*.toc, doc/*.log, doc/*.out, doc/*.tmp ## Implementation and References The implementation of the Fossil-specific glob pattern handling is here: :File |:Description -------------------------------------------------------------------------------- [`src/glob.c`][] | pattern list loading, parsing, and generic matching code [`src/file.c`][] | application of glob patterns to file names [`src/glob.c`]: https://www.fossil-scm.org/index.html/file/src/glob.c [`src/file.c`]: https://www.fossil-scm.org/index.html/file/src/file.c See the [Adding Features to Fossil][aff] document for broader details about finding and working with such code.

This document explains the commonalities and divergences between [POSIX `grep`](http://pubs.opengroup.org/onlinepubs/9699919799/utilities/grep.html) and Fossil `grep`. ## Options Fossil `grep` supports only a small subset of the options specified for POSIX `grep`: | Option | Meaning |--------|------------------------------------------------------------- | `-i` | ignore case in matches | `-l` | list a checkin ID prefix for matching historical versions of the file | `-v` | print each checkin ID considered, regardless of whether it matches That leaves many divergences at the option level from POSIX `grep`: * There is no built-in way to get a count of matches, as with `grep -c`. * You cannot give more than one pattern, as with `grep -e` or `grep -f`. * There is no equivalent of `grep -F` to do literal fixed-string matches only. * `fossil grep -l` does not do precisely the same thing as POSIX `grep -l`: it lists checkin ID prefixes, not file names. * Fossil always gives the line number in its output, which is to say that it acts like `grep -n`. There is no way to disable the line number in `fossil grep` output. * There is no way to suppress all output, returning only a status code to indicate whether the pattern matched, as with `grep -q`. * There is no way to suppress error output, as with `grep -s`. * Fossil `grep` does not accept a directory name for Fossil to expand to the set of all files under that directory. This means Fossil `grep` has no equivalent of the common POSIX `grep -R` extension. (And if it did, it would probably have a different option letter, since `-R` in Fossil has a different meaning, by convention.) * You cannot invert the match, as with `grep -v`. Patches to remove those limitations will be thoughtfully considered. ## Regular Expression Dialect Fossil contains a built-in regular expression engine implementing a subset of the [POSIX extended regular expression][ere] dialect: [ere]: https://en.wikipedia.org/wiki/Regular_expression#POSIX_extended | Atom | Meaning |---------|------------------------------------------------------------- | `X*` | zero or more occurrences of X | `X+` | one or more occurrences of X | `X?` | zero or one occurrences of X | `X{p,q}`| between p and q occurrences of X, inclusive | `(X)` | match X | <tt>X\|Y</tt>| X or Y | `^X` | X occurring at the beginning of a line | `X$` | X occurring at the end of a line | `.` | Match any single character | `\c` | Character `c` where `c` is one of <tt>{}()[]\|\*+?.\\</tt> | `\c` | C-language escapes for `c` in `afnrtv`. ex: `\t` or `\n` | `\uXXXX`| Where XXXX is exactly 4 hex digits, Unicode value XXXX | `\xXX` | Where XX is exactly 2 hex digits, Unicode value XX | `[abc]` | Any single character from the set `abc` | `[^abc]`| Any single character not in the set `abc` | `[a-z]` | Any single character in the range `a-z` | `[^a-z]`| Any single character not in the range `a-z` | `\b` | Word boundary | `\w` | Word character: `[A-Za-z0-9_]` | `\W` | Non-word character: `[^A-Za-z0-9_]` | `\d` | Digit: `[0-9]` | `\D` | Non-digit: `[^0-9]` | `\s` | Whitespace character: `[ \t\r\n\v\f]` | `\S` | Non-whitespace character: `[^ \t\r\n\v\f]` There are several restrictions in Fossil `grep` relative to a fully POSIX compatible regular expression engine. Among them are: * There is currently no support for POSIX character classes such as `[:lower:]`. * Fossil `grep` does not currently attempt to take your operating system's locale settings into account when doing this match. Since Fossil has no way to mark a given file as having a particular encoding, Fossil `grep` assumes the input files are in UTF-8 format. This means Fossil `grep` will not work correctly if the files in your repository are in an encoding that is not backwards-compatible with ASCII, such as UTF-16. Partially compatible encodings such as ISO 8859 should work with Fossil `grep` as long as you stick to their ASCII-compatible subset. The Fossil `grep` language is not a strict subset of POSIX extended regular expressions. Some of the features documented above are well-understood extensions to it, such as the "word" features `\b`, `\w` and `\W`. Fossil `grep` is based on the Unicode engine from [SQLite's FTS5 feature][fts5]. This means it does do things like Unicode-aware case folding. Therefore, it is usually a user error to attempt to substitute `[a-z]` for a lack of the POSIX character class `[:lower:]` if you are grepping over pretty much any human written language other than English. Use `fossil grep -i` instead, which does Unicode case folding. [fts5]: https://www.sqlite.org/fts5.html ## Algorithm Details Fossil `grep` uses a [nondeterministic finite automaton][nfa] for matching, so the performance is bounded by ***O(nm)*** where ***n*** is the size of the regular expression and ***m*** is the size of the input string. [nfa]: https://en.wikipedia.org/wiki/Nondeterministic_finite_automaton In order to avoid [ReDoS attacks][redos], the Fossil regular expression matcher was purposely written to avoid [implementation choices][rei] which have the potential to require exponential evaluation time. This constrains the possible feature set we can support in the Fossil `grep` dialect. For instance, we are unlikely to ever add support for [backtracking][bt]. [redos]: https://en.wikipedia.org/wiki/ReDoS [rei]: https://en.wikipedia.org/wiki/Regular_expression#Implementations_and_running_times [bt]: https://en.wikipedia.org/wiki/Backtracking The `X{p,q}` operator expands to `p` copies of `X` followed by `q-p` copies of `X?` before RE evaluation. The ***O(nm)*** performance bound above remains true for this case, but realize that it applies to the RE *after* this expansion, not to the form as given by the user. In other words, as `q-p` increases, so does the RE evaluation time. |

There is a loose hierarchy of terms used instead of “hash†in various parts of the Fossil UI, which we cover in the sections below. ## Names Several Fossil interfaces accept [a wide variety of check-in names][cin]: commit artifact hashes, ISO8601 date strings, branch names, etc. Fossil interfaces that accept any of these options usually document the parameter as “NAMEâ€, so we will use that form to refer to this specialized use. Artifact hashes are only one of many different types of NAME. We use the broad term “NAME†to refer to the whole class of options. We use more specific terms when we mean one particular type of NAME. ## Versions When an artifact hash refers to a specific commit, Fossil sometimes calls it a “VERSION,†a “commit ID,†or a “check-in ID.†We may eventually settle on one of these terms, but all three are currently in common use within Fossil’s docs, UI, and programming interfaces. A VERSION is a specific type of artifact hash, distinct from, let us say, a wiki article artifact hash. A unique prefix of a VERSION hash is itself a VERSION. That is, if your repository has exactly one commit artifact with a hash prefix of “abc123â€, then that is a valid version string as long as it remains unambiguous. ## <a id="uvh"></a>UUIDs Fossil uses the term “UUID†as a short alias for “artifact hash†in its internals. There are a few places where this leaks out into external interfaces, which we cover in the sections below. Going forward, we prefer one of the terms above in public interfaces instead. Whether this short alias is correct is debateable. One argument is that since "UUID" is an acronym for “Universally Unique Identifier,†and both SHA1 and SHA3-256 are larger and stronger than the 128-bit algorithms used by “proper†UUIDs, Fossil artifact hashes are *more universally unique*. It is therefore quibbling to say that Fossil UUIDs are not actually UUIDs. One wag suggested that Fossil artifact hashes be called MUIDs: multiversally unique IDs. The common counterargument is that the acronym “UUID†was created for [a particular type of universally-unique ID][uuid], with particular ASCII and bitfield formats, and with particular meaning given to certain of its bits. In that sense, no Fossil “UUID†can be used as a proper UUID. Be warned: attempting to advance the second position on the Fossil discussion forum will get you nowhere at this late date. We’ve had the debates, we’ve done the engineering, and we’ve made our evaluation. It’s a settled matter: internally within Fossil, “UUID†is defined as in this section’s leading paragraph. To those who remain unconvinced, “fixing†this would require touching almost every source code file in Fossil in a total of about a thousand separate locations. (Not exaggeration, actual data.) This would be a massive undertaking simply to deal with a small matter of terminology, with a high risk of creating bugs and downstream incompatibilities. Therefore, we are highly unlikely to change this ourselves, and we are also unlikely to accept a patch that attempts to fix it. ### Repository DB Schema The primary place where you find "UUID" in Fossil is in the `blob.uuid` table column, in code dealing with that column, and in code manipulating *other* data that *refers* to that column. This is a key lookup column in the most important Fossil DB table, so it influences broad swaths of the Fossil internals. For example, C code that refers to SQL result data on `blob.uuid` usually calls the variable `zUuid`. That value may then be inserted into a table like `ticket.tkt_uuid`, creating a reference back to `blob.uuid`, and then be passed to a function like `uuid_to_rid()`. There is no point renaming a single one of these in isolation: it would create needless terminology conflicts, making the code hard to read and understand, risking the creation of new bugs. You may have local SQL code that digs into the repository DB using these column names. While you may rest easy, assured now that we are highly unlikely to ever rename these columns, the Fossil repository DB schema is not considered an external user interface, and internal interfaces are subject to change at any time. We suggest switching to a more stable API: [the JSON API][japi], [`timeline.rss`][trss], [TH1][th1], etc. ### TH1 Scripting Interfaces Some [TH1][th1] interfaces expose Fossil internals flowing from `blob.uuid`, so “UUID†is a short alias for “artifact hash†in TH1. For example, the `$tkt_uuid` variable — available when [customizing the ticket system][ctkt] — is a ticket artifact hash, exposing the `ticket.tkt_uuid` column, which has a SQL relation to `blob.uuid`. TH1 is a longstanding public programming interface. We cannot rename its interfaces without breaking existing TH1 Fossil customizations. We are also unlikely to provide a parallel set of variables with “better†names, since that would create a mismatch with respect to the internals they expose, creating a different sort of developer confusion in its place. ### JSON API Parameters and Outputs [The JSON API][japi] frequently uses the term “UUID†in the same sort of way, most commonly in [artifact][jart] and [timeline][jtim] APIs. As with TH1, we can’t change this without breaking code that uses the JSON API as originally designed, so we take the same stance. ### `manifest.uuid` If you have [the `manifest` setting][mset] enabled, Fossil writes a file called `manifest.uuid` at the root of the check-out tree containing the commit hash for the current checked-out version. Because this is a public interface that existing code depends on, we are unwilling to rename the file.

If you are concerned about this and its implications for Fossil, simply [./quickstart.wiki#install|upgrade to Fossil 2.1 or later], and the problem will go away. Everything will continue to work as before. * Legacy repositories will continue working just as they always have, without any conversions or upgrades. * Historical check-ins will keep their same historical SHA1 names. * New check-ins will get more secure SHA3-256 hash names. * Everything will continue as if nothing happened. * Your workflow will be unchanged. But if you are curious and want a deeper understanding of what is going on, read on... <h2>Introduction</h2> The first snapshot-based distributed version control system was [http://www.monotone.ca|Monotone]. Many of the ideas behind the design of Fossil were copied from Monotone, including the use of a SHA1 hash to assign names to artifacts. Git and Mercurial did the same thing. The SHA1 hash algorithm is used only to create names for artifacts in Fossil (and in Git, Mercurial, and Monotone). It is not used for security. Nevertheless, when the [http://www.shattered.io|SHAttered attack] found two different PDF files with the same SHA1 hash, many users learned that "SHA1 is broken". They see that Fossil (and Git, Mercurial, and Monotone) use SHA1 and they therefore conclude that "Fossil is broken". This is not true, but it is a public relations problem. So the decision was made to migrate Fossil away from SHA1. This article describes how that migration is occurring. <h2>Use Of Hardened SHA1</h2> In Fossil version 2.0 ([/timeline?c=version-2.0|2017-03-03]), the internal SHA1 implementation was changed from a generic FIPS PUB 180-4 SHA1 implementation to a "Hardened SHA1" [[https://github.com/cr-marcstevens/sha1collisiondetection|1]] [[https://marc-stevens.nl/research/papers/C13-S.pdf|2]]. The Hardened SHA1 algorithm automatically detects when the artifact being hashed is specifically designed to exploit the known weaknesses in the SHA1 algorithm, and when it detects such an attack it changes the hash algorithm (by increasing the number of rounds in the compression function) to make the algorithm secure again. If the attack detection gets a false possible, that means that Hardened SHA1 will get a different answer than the standard FIPS PUB 180-4 SHA1, but the creators of Hardened SHA1 (see the second paper [[https://marc-stevens.nl/research/papers/C13-S.pdf|2]]) report that the probability of a false positive is vanishingly small - less than 1 false positive out of 10<sup><font size=1>27</font></sup> hashes. Hardened SHA1 is slower (and a lot bigger) but Fossil does not do that much hashing, so performance is not really an issue. All versions of Fossil moving forward will use Hardened SHA1. So if someone says "SHA1 is broken, and Fossil uses SHA1, therefore Fossil is broken," you can rebut the argument by pointing out that Fossil uses <em>Hardened SHA1</em>, not generic SHA1, and Hardened SHA1 is <em>not</em> broken. <h2>Support For SHA3-256</h2> Prior to Fossil version 2.0 ([/timeline?c=version-2.0|2017-03-03]), all artifacts in all Fossil repositories were named by only a SHA1 hash. Version 2.0 extended the [./fileformat.wiki|Fossil file format] to allow artifacts to be named by either SHA1 or SHA3-256 hashes. (SHA3-256 is the only variant of SHA3 that Fossil uses for artifact naming, so for the remainder of this article it will be called simply "SHA3". Similarly, "Hardened SHA1" will shortened to "SHA1" in the remaining text.) To be clear: Fossil (version 2.0 and later) allows the SHA1 and SHA3 hashes to be mixed within the same repository. Older check-ins, created years ago, continue to be named using their legacy SHA1 hashes while newer check-ins are named using modern SHA3 hashes. There is no need to "convert" a repository from SHA1 over to SHA3. You can see this in Fossil itself. The recent [9d9ef82234f63758] check-in uses a SHA3 hash whereas the older [1669115ab9d05c18] check-in uses a SHA1 hash. Other than permitting the use of SHA3 in addition to SHA1, there were no file format changes in Fossil version 2.0 relative to the previous version 1.37. Both Fossil 2.0 and Fossil 1.37 read and write all the same repositories and sync with one another, as long as none of the repositories contain artifacts named using SHA3. If a repository does contain artifacts named using SHA3, Fossil 1.37 will not know how to interpret those artifacts and will generate various warnings and errors. <h2>How Fossil Decides Which Hash Algorithm To Use For New Artifacts</h2> If newer versions of Fossil are able to use either SHA1 or SHA3 to name artifacts, which hash algorithm is actually used? That question is answered by the "hash policy". These are the supported hash policies: <table cellpadding=10> <tr> <td valign='top'>sha1</td> <td>Name all new artifacts using the (Hardened) SHA1 hash algorithm.</td> </tr> <tr> <td valign='top'>auto</td> <td>Name new artifacts using the SHA1 hash algorithm, but if any artifacts are encountered which are already named using SHA3, then automatically switch the hash policy to "sha3"</td> </tr> <tr> <td valign='top'>sha3</td> <td>Name new artifacts using the SHA3 hash algorithm if the artifact does not already have a SHA1 name. If the artifact already has a SHA1 name, then continue to use the older SHA1 name. Use SHA3 for new artifacts that have never before been encountered.</td> </tr> <tr> <td valign='top'>sha3-only</td> <td>Name new artifacts using the SHA3 hash algorithm even if the artifact already has a SHA1 name. In other words, force the use of SHA3. This can cause some artifacts to be added to the repository twice, once under their SHA1 name and again under their SHA3 name, but delta compression will prevent that from causing repository size problems.</td> </tr> <tr> <td valign='top'>shun-sha1</td> <td>Like "sha3-only" but at this level do not accept a push of SHA1-named artifacts. If another Fossil instance tries to push a SHA1-named artifact, that artifact is discarded and ignored. </tr> </table> For Fossil 2.0, and obviously also for Fossil 1.37 and before, the only hash policy supported was the one now called "sha1", meaning that all new artifacts were named using a SHA1 hash. Even though Fossil 2.0 added the capability of understanding SHA3 hashes, it never actually generates any SHA3 hashes. From Fossil 2.1 through 2.9, the default hash policy for legacy repositories changed to "auto", meaning that Fossil continued to generate only SHA1 hashes until it encountered one artifact with a SHA3 hash. Once those older versions of Fossil saw a single SHA3 hash, they automatically switched to "sha3" mode and thereafter generated only SHA3 hashes. When a new repository is created by cloning, the hash policy is copied from the parent. For new repositories created using the [/help?cmd=new|fossil new] command the default hash policy is "sha3". That means new repositories will normally hold nothing except SHA3 hashes. The hash policy for new repositories can be overridden using the "--sha1" option to the "fossil new" command. If you are still on Fossil 2.1 through 2.9 but you want Fossil to go ahead and start using SHA3 hashes, change the hash policy to "sha3" using a command like this: <blockquote><verbatim> fossil hash-policy sha3 </verbatim></blockquote> The next check-in will use a SHA3 hash, so that when that check-in is pushed to colleagues, their clones will include the new SHA3-named artifact, so their local Fossil instances will automatically convert their clones to "sha3" mode as well. Of course, if some members of your team stubbornly refuse to upgrade past Fossil 1.37, you should avoid changing the hash policy and creating artifacts with SHA3 names, because once you do that your recalcitrant coworkers will no longer be able to collaborate. <h2>A Pure SHA3 Future</h2> Fossil 2.10 changed the default hash policy to "sha3" mode even for legacy repositories, so if you upgrade to the latest version of Fossil, all of your new artifacts will use a SHA3 hash. Legacy SHA1 artifacts continue to use their original names, but new artifacts will use SHA3 names. You might not even notice this automatic change over to stronger hashes. We decided to make the change to pure SHA3 since the last known distributor of Fossil 1.x binaries — Debian 9 — was finally replaced in June 2019 by Debian 10, which included Fossil 2.8. All other known sources of Fossil 1.x binaries upgraded well before that point. |

Click on nodes of any timeline graph to see diffs between the two selected versions. 2. Add the "--tk" option to "[/help?cmd=diff | fossil diff]" commands to get a pop-up window containing a complete side-by-side diff. (NB: The pop-up window is run as a separate Tcl/Tk process, so you will need to have Tcl/Tk installed on your machine for this to work. Visit [http://www.activestate.com/activetcl] to for a quick download of Tcl/Tk if you do not already have it on your system.) 3. The "[/help/clean | fossil clean -x]" command is a great alternative to "make clean". You can use "[/help/clean | fossil clean -f]" as a slightly safer alternative if the "ignore-glob" setting is not set. WARNING: make sure you did a "fossil add" for all source-files you plan to commit, otherwise those files will be deleted without warning. 4. Use "[/help?cmd=all | fossil all changes]" to look for any uncommitted edits in any of your Fossil projects. Use "[/help?cmd=all | fossil all pull]" on your laptop prior to going off network (for example, on a long plane ride) to make sure you have all the latest content locally. Then run "[/help/all|fossil all push]" when you get back online to upload your changes. 5. To see an entire timeline, type "all" into the "Max:" entry box. 6. You can manually add a "c=CHECKIN" query parameter to the timeline URL to get a snapshot of what was going on about the time of some check-in. The "CHECKIN" can be [./checkin_names.wiki | any valid check-in or version name], including tags, branch names, and dates. For example, to see what was going on in the Fossil repository on 2008-01-01, visit [http://www.fossil-scm.org/fossil/timeline?c=2008-01-01]. 7. Further to the previous two hints, there are lots of query parameters that you can add to timeline pages. The available query parameters are tersely documented [/help?cmd=/timeline | here]. 8. You can run "[/help?cmd=test-diff | fossil test-diff --tk $file1 $file2]" to get a pop-up window with side-by-side diffs of two files, even if neither of the two files is part of any Fossil repository. Note that this command is "test-diff", not "diff". 9. On web pages showing the content of a file (for example [http://www.fossil-scm.org/fossil/artifact/c7dd1de9f]) you can manually add a query parameter of the form "ln=FROM,TO" to the URL that will cause the range of lines indicated to be highlighted. This is useful in pointing out a few lines of code using a hyperlink in an email or text message. Example: [http://www.fossil-scm.org/fossil/artifact/c7dd1de9f?ln=28,30]. Adding the "ln" query parameter without any argument simply turns on line numbers. This feature only works right with files with a mimetype of text/plain, of course. 10. When editing documentation to be checked in as managed files, you can preview what the documentation will look like by using the special "ckout" branch name in the "doc" URL while running "fossil ui". See the [./embeddeddoc.wiki | embedded documentation] for details. |

[100]: https://en.wikipedia.org/wiki/Distributed_version_control [105]: /timeline?a=1970-01-01&n=10 [110]: https://sqlite.org/crew.html [115]: https://sqlite.org/ Though Fossil was originally written specifically to support SQLite, it is now also used by countless other projects. The SQLite architect (drh) is still the top committer to Fossil, but there are also [many other contributors][120]. [120]: /reports?type=ci&view=byuser ## History The SQLite project start out using [CVS][300], as CVS was the most commonly used version control system in that era (circa 2000). CVS was an amazing version control system for its day in that it allowed multiple developers to be editing the same file at the same time. [300]: https://en.wikipedia.org/wiki/Concurrent_Versions_System Though innovative and much loved in its time, CVS was not without problems. Among those was a lack of visibility into the project history and the lack of integrated bug tracking. To try to address these deficiencies, the SQLite author developed the [CVSTrac][305] wrapper for CVS beginning in [2002][310]. [305]: http://cvstrac.org/ [310]: http://cvstrac.org/fossil/timeline?a=19700101&n=10 CVSTrac greatly improved the usability of CVS and was adopted by other projects. CVSTrac also [inspired the design][315] of [Trac][320], which was a similar system that was (and is) far more widely used. [315]: https://trac.edgewall.org/wiki/TracHistory [320]: https://trac.edgewall.org/ Historians can see the influence of CVSTrac on the development of SQLite. [Early SQLite check-ins][325] that happened before CVSTrac often had a check-in comment that was just a "smiley". That was not an unreasonable check-in comment, as check-in comments were scarcely seen and of questionable utility in raw CVS. CVSTrac changed that, making check-in comments more visible and more useful. The SQLite developers reacted by creating [better check-in comments][330]. [325]: https://sqlite.org/src/timeline?a=19700101&n=10 [330]: https://sqlite.org/src/timeline?c=20030101&n=10&nd At about this same time, the [Monotone][335] system appeared. Monotone was one of the first distributed version control systems. As far as this author is aware, Monotone was the first VCS to make use of SHA1 to identify artifacts. Monotone stored its content in an SQLite database, which is what brought it to the attention of the SQLite architect. These design choices were a major source of inspiration for Fossil. [335]: https://www.monotone.ca/ Beginning around 2005, the need for a better version control system for SQLite began to become evident. The SQLite architect looked around for a suitable replacement. Monotone, Git, and Mercurical were all considered. But at that time, none of these supported sync over ordinary HTTP, none could be run from an inexpensive shell account on a leased server (this was before the widespread availability of affordable virtual machines), and none of them supported anything resembling the wiki and ticket features of CVSTrac that had been found to be so useful. And so, the SQLite architect began writing his own DVCS. Early prototypes were done in [TCL][340]. As experiments proceeded, however, it was found that the low-level byte manipulates needed for things like delta compression and computing diffs were better implemented in plain old C. Experiments continued. Finally, a prototype capable of self-hosting was devised on [2007-07-16][345]. [340]: https://www.tcl.tk/ [345]: https://fossil-scm.org/fossil/timeline?c=200707211410&n=10 The first project hosted by Fossil was Fossil itself. After a few months of development work, the code was considered stable enough to begin hosting the [SQLite documentation repository][350] which was split off from the main SQLite CVS repository on [2007-11-12][355]. After two years of development work on Fossil, the SQLite source code itself was transfered to Fossil on [2009-08-11][360].

Administrators can use hooks to help enforce policy or connect Fossil to a continuous integration (CI) system. ## Interim Documentation. * This is a work-in-progress. The interface is in flux. For the time being, the documentation as a list of bullet points. We hope to transform this into a proper document later, after things settle down. * Contributions and suggestions to the hook system and/or the documentation are welcomed. ## General Notes. * Each hooks has a "type", a "sequence", and a "command". The command is a shell command that runs at the appropriate time. The type is currently one of "after-receive", "before-commit", "commit-msg", or "disabled". The sequence is an arbitrary integer. * There can be multiple hooks of the same type. When that is the case, the hooks are run in order of ascending sequence. * Use the "fossil hook" command to create, edit, and delete hooks. * Use the "fossil hook test" command to test new hooks. ## Hook Scripts * All scripts are expected to run relatively quickly. If a long-running process is started by a hook, it should be run in the background so that the original script can return. * The "%F" sequence inside the script is translated into the name of the fossil executable. * The "%R" sequence in the script is translated in to the name of the repository. * The "%A" sequence becomes the name of an auxiliary input files, the meaning of which depends on the hook type. The auxiliary filename might be an empty string. Take care to use appropriate quoting! ## Disabled Hooks * Hooks with type "disabled" never run. They are a place-holder for scripts that might be converted to some other hook-type later. For example, the command "fossil hook edit --type disabled ID" can be used to temporarily disable the hook named ID, and then "fossil hook edit --type after-receive ID" can be used to reenable it later. ## After-Receive Hooks * The "after-receive" hook is run by [the backoffice](./backoffice.md) whenever new artifacts are received into the repository. The artifacts have already been committed and so there is nothing that the after-receive hook can do to block them. * The after-receive hooks are intended to be run on a server to start up a background testing or CI process. But they can also be run on the client side. The key point is that after-receive hooks are invoked by backoffice, so backoffice must be running in order to fire after-receive hooks. * The exit code from the after-receive script is ignored. * The standard input to the after-receive hook is a list of new artifacts, one per line. The first token on each line is the hash of the new artifact. After the hash is a human-readable text description of what the artifact represents. * Sometimes the same artifact can represent two or more things. For example, the same artifact might represent two or more files in the check-out (assuming the files hold identical content). In that case, the text description that is input to the after-receive hook only shows one of the possible uses for the artifact. * If two or more pushes occur against a repository at about the same time, then the set of artifacts added by both pushes might be combined into a single after-receive callback. * Fossil holds a write transaction on the repository while the after-receive hook is running. If the script needs to access the database, then the database will need to be in WAL mode so that readers can co-exist with the writer. Or the script might just launch a background process that waits until the hook script finishes and the transaction commits before it tries to access the repository database. * A push might not deliver all of the artifacts for a checkin. If Fossil knows that a /xfer HTTP request is incomplete, it will defer running the after-receive push for 60 seconds, or unti a complete /xfer request is received. This helps to prevent after-receive hooks from running when incomplete checkins exist in the repository, but it does not provide hard guarantees, as there is no way to do that in a distributed system. * The list of artifacts delivered to standard input of the after-receive hook will not contain more than 24-hours worth of artifacts. If the backoffice has been shut down for a while such that after-receive hooks have not been running, and more than 24-hours of changes have accumulated since the last run of an after-receive hook, then only the most recent 24-hours is included in the input. ## Before-Commit Hooks * Before-commit hooks run during the "fossil commit" command before the user is prompted for the check-in comment. Fossil holds a write-transaction on the repository when the before-commit hook is running, so the repository needs to be in WAL mode if the script needs to access the repository. * The %A substitution is the name of a "commit description file" that shows the details of the commit in progress. To see what a "commit description file" looks like, set a before-commit hook with a command of "cat %Q" and then run a sample commit with the --dry-run option. * If any before-commit hook returns a non-zero exit code, then the commit is abandoned. All before-commit hooks must exit(0) in order for the commit to proceed. * The --no-validate flag to the "fossil commit" command prevents any before-commit hooks from running. * The --trace flag to the "fossil commit" command shows each before-commit hook as it is run. * If a before-commit hook fails, it should print an error message on standard output or standard error. Otherwise, the user won't know what went wrong, because Fossil won't tell them. * Nothing is written to standard input of the before-commit hook. The information transmitted to the before-commit hook is contained in the "%A" auxiliary file. The before-commit hook must open and read that file if it wants access to the commit information. ## Commit-Msg Hooks * Commit-msg hooks are not yet implemented. * The commit-msg hooks run during "fossil commit" after the check-in messages has been entered by the user. The "%A" argument to the commit-msg hook is the text of the commit message. The intent of the commit-msg hook is to validate the text of the commit message to (for example) check for typos or ensure that it conforms to standards. * If any commit-msg hook returns a non-zero exit code, then the commit is abandoned. All commit-msg hooks must exit(0) in order for the commit to proceed. * Commit-msg hooks are advisory only. Each developer is in total control of the local repository and can easily bypass the hooks to cause a non-conforming checkin to be committed. |

Storing pre-compressed data files in a Fossil repository defeats both of these space-saving measures: 1. Binary data compression algorithms turn the file data into [pseudorandom noise][prn].² Typical data compression algorithms are not [hash functions][hf], where the goal is that a change to each bit in the input has a statistically even chance of changing every bit in the output, but because they do approach that pathological condition, pre-compressed data tends to defeat Fossil’s delta compression algorithm, there being so little correlation between two different outputs from the binary data compression algorithm. 2. An ideal lossless binary data compression algorithm cannot be applied more than once to make the data even smaller, since random noise is incompressible. The consequence for our purposes here is that pre-compressed data doesn’t benefit from Fossil’s zlib compression. You might then ask, what does it matter if the space savings comes from the application file format (e.g. JPEG, DOCX, Zip, etc.) or from Fossil itself? It really doesn’t, as far as point 2 above goes, but point 1 causes the Fossil repository to balloon out of proportion to the size of the input data change on each checkin. This article will illustrate that problem, quantify it, and give a solution to it. [dc]: ./delta_format.wiki [hf]: https://en.wikipedia.org/wiki/Hash_function [prn]: https://en.wikipedia.org/wiki/Pseudorandomness [zl]: http://www.zlib.net/ ## Affected File Formats In this article’s core experiment, we use 2D image file formats, but this article’s advice also applies to many other file types. For just a few examples out of what must be thousands: * **Microsoft Office**: The [OOXML document format][oox] used from Office 2003 onward (`.docx`, `.xlsx`, `.pptx`, etc.) are Zip files containing an XML document file and several collateral files. * **Libre Office**: For the purposes of this article, its [OpenDocument Format][odf] is designed the same basic way as OOXML. * **Java**: A Java [`.jar` file][jcl] is a Zip file containing JVM `.class` files, manifest files, and more. * **Windows Installer:** An [`*.msi` file][wi] is a proprietary database format that contains, among other things, [Microsoft Cabinet][cab]-compressed files, which in turn may hold Windows executables, which [may themselves be compressed][exc]. * **SVG, PDF, TIFF, etc.**: Many file formats are available in both compressed and uncompressed forms. You should use the uncompressed form with Fossil wherever practical, as we will show below. [cab]: https://en.wikipedia.org/wiki/Cabinet_(file_format) [exc]: https://en.wikipedia.org/wiki/Executable_compression [jcl]: https://en.wikipedia.org/wiki/Java_(programming_language) [odf]: https://en.wikipedia.org/wiki/OpenDocument [oox]: https://en.wikipedia.org/wiki/Office_Open_XML [wi]: https://en.wikipedia.org/wiki/Windows_Installer ## Demonstration The companion `image-format-vs-repo-size.ipynb` file ([download][nbd], [preview][nbp]) is a [JupyterLab][jl] notebook implementing the following experiment: 1. Create a new minimum-size Fossil repository. Save this initial size. 2. Use [ImageMagick][im] via [Wand][wp] to generate a JPEG file of a particular size — currently 256 px² — filled with Gaussian noise to make data compression more difficult than with a solid-color image. 3. Check that image into the new Fossil repo, and remember that size. 4. Change a random pixel in the image to a random RGB value, save that image, check it in, and remember the new Fossil repo size. 5. Iterate on step 4 some number of times — currently 10 — and remember the Fossil repo size at each step. 6. Repeat the above steps for BMP, TIFF,³ and PNG. 7. Create a bar chart showing how the Fossil repository size changes with each checkin. We chose to use JupyterLab for this because it makes it easy for you to modify the notebook to try different things. Want to see how the results change with a different image size? Easy, change the `size` value in the second cell of the notebook. Want to try more image formats? You can put anything ImageMagick can recognize into the `formats` list. Want to find the break-even point for images like those in your own repository? Easily done with a small amount of code. [im]: https://www.imagemagick.org/ [jl]: https://jupyter.org/ [nbd]: ./image-format-vs-repo-size.ipynb [nbp]: https://nbviewer.jupyter.org/urls/fossil-scm.org/fossil/doc/trunk/www/image-format-vs-repo-size.ipynb [wp]: http://wand-py.org/ ## Results Running the notebook gives a bar chart something likeâ´ this: ![results bar chart](./image-format-vs-repo-size.svg) There are a few key things we want to draw your attention to in that chart: * BMP and uncompressed TIFF are nearly identical in size for all checkins, and the repository growth rate is negligible past the first commit.âµ We owe this economy to Fossil’s delta compression feature: it is encoding each of those single-pixel changes in a very small amount of repository space. * The JPEG and TIFF bars increase by large amounts on most checkins even though each checkin *also* encodes only a *single-pixel change*. * The size of the first checkin in the BMP and TIFF cases is roughly the same as that for the PNG case, because both PNG and Fossil use the zlib binary data compression algorithm. This shows that for repos where the image files are committed only once, there is virtually no penalty to using BMP or TIFF over PNG. The file sizes likely differ only because of differences in zlib settings between the cases. * Because JPEG’s lossy nature allows it to start smaller and have smaller size increases than than PNG, the crossover point with BMP/TIFF isn’t until 7-9 checkins in typical runs of this [Monte Carlo experiment][mce]. Given a choice among these four file formats and a willingness to use lossy image compression, a rational tradeoff is to choose JPEG for repositories where each image will change fewer than that number of times. [mce]: https://en.wikipedia.org/wiki/Monte_Carlo_method ## Automated Recompression Since programs that produce and consume binary-compressed data files often make it either difficult or impossible to work with the uncompressed form, we want an automated method for producing the uncompressed form to make Fossil happy while still having the compressed form to keep our content creation applications happy. This `Makefile` shouldⶠdo that for BMP, PNG, SVG, and XLSX files: .SUFFIXES: .bmp .png .svg .svgz .svgz.svg: gzip -dc < $< > $@ .svg.svgz: gzip -9c < $< > $@ .bmp.png: convert -quality 95 $< $@ .png.bmp: convert $< $@ SS_FILES := $(wildcard spreadsheet/*) all: $(SS_FILES) illus.svg image.bmp doc-big.pdf reconstitute: illus.svgz image.png ( cd spreadsheet ; zip -9 ../spreadsheet.xlsx) * ) qpdf doc-big.pdf doc-small.pdf $(SS_FILES): spreadsheet.xlsx unzip $@ -d $< doc-big.pdf: doc-small.pdf qpdf --stream-data=uncompress $@ $< This `Makefile` allows you to treat the compressed version as the process input, but to actually check in only the changes against the uncompressed version by typing “`make`†before “`fossil ci`â€. This is not actually an extra step in practice, since if you’ve got a `Makefile`-based project, you should be building (and testing!) it before checking each change in anyway! Because this technique is based on dependency rules, only the necessary files are generated on each `make` command. You only have to run “`make reconstitute`†*once* after opening a fresh Fossil checkout to produce those compressed sources. After that, you work with the compressed files in your content creation programs. Your build system might include some kind of bootstrapping or auto-configuration step that you could attach this to, so that it doesn’t need to be run by hand. This `Makefile` illustrates two primary strategies: ### Input and Output File Formats Differ by Extension In the case of SVG and the bitmap image formats, the file name extension differs between the cases, so we can use `make` suffix rules to get the behavior we want. The top half of the `Makefile` just tells `make` how to map from `*.svg` to `*.svgz` and vice versa, and the same for `*.bmp` to/from `*.png`. ### Input and Output Use the Same Extension We don’t have that luxury for Excel and PDF files, each for a different reason: * **Excel:** Excel has no way to work with the unpacked Zip file contents at all, so we have to unpack it into a subdirectory, which is what we check into Fossil. On making a fresh Fossil checkout, we have to pack that subdirectory’s contents back up into an `*.xlsx` file with “`make reconstitute`†so we can edit it with Excel again. * **PDF:** All PDF readers can display an uncompressed PDF file, but many PDF-*producing* programs have no option for uncompressed output. Since the file name extension is the same either way, we treat the compressed PDF as the source to the process, yielding an automatically-uncompressed PDF for the benefit of Fossil. Unlike with the Excel case, there is no simple “file base name to directory name†mapping, so we just created the `-big` to `-small` name scheme here. ---- ## Footnotes and Digressions 1. This problem is not Fossil-specific. Several other programs also do delta compression, so they’ll also be affected by this problem: [rsync][rs], [Unison][us], [Git][git], etc. You should take this article’s advice when using all such programs, not just Fossil. When using file copying and synchronization programs *without* delta compression, on the other hand, it’s best to use the most highly-compressed file format you can tolerate, since they copy the whole file any time any bit of it changes. 2. In fact, a good way to gauge the effectiveness of a given compression scheme is to run its output through the same sort of tests we use to gauge how “random†a given [PRNG][prng] is. Another way to look at it is that if there is a discernible pattern in the output of a compression scheme, that constitutes *information* (in [the technical sense of that word][ith]) that could be further compressed. 3. We're using *uncompressed* TIFF here, not [LZW][lzw]- or Zip-compressed TIFF, either of which would give similar results to PNG, which is always zlib-compressed. 4. The raw data changes somewhat from one run to the next due to the use of random noise in the image to make the zlib/PNG compression more difficult, and the random pixel changes. Those test design choices make this a [Monte Carlo experiment][mce]. We’ve found that the overall character of the results doesn’t change from one run to the next. 5. It’s not clear to me why there is a one-time jump in size for BMP and TIFF past the first commit. I suspect it is due to the SQLite indices being initialized for the first time. Page size inflation might have something to do with it as well, though we tried to control that by rebuilding the initial DB with a minimal page size. If you re-run the program often enough, you will sometimes see the BMP or TIFF bar jump higher than the other, again likely due to one of the repos crossing a page boundary. Another curious artifact in the data is that the BMP is slightly larger than for the TIFF. This goes against expectation because a low-tech format like BMP should have a small edge in this test because TIFF metadata includes the option for multiple timestamps, UUIDs, etc., which bloat the checkin size by creating many small deltas. 6. The `Makefile` above is not battle-tested. Please report bugs and needed extensions [on the forum][for].

The pages you see here are all [./wikitheory.wiki | wiki] or [./embeddeddoc.wiki | embedded documentation] or (in the case of the [/uv/download.html|download] page) [./unvers.wiki | unversioned files]. When you clone Fossil from one of its [./selfhost.wiki | self-hosting repositories], you get more than just source code - you get this entire website. 3. <b>Self-Contained</b> - Fossil is a single self-contained stand-alone executable. To install, simply download a [/uv/download.html | precompiled binary] for Linux, Mac, or Windows and put it on your $PATH. [./build.wiki | Easy-to-compile source code] is also available. 4. <b>Simple Networking</b> - No custom protocols or TCP ports. Fossil uses ordinary HTTP (or HTTPS or SSH) for network communications, so it works fine from behind restrictive firewalls, including [./quickstart.wiki#proxy|proxies]. The protocol is [./stats.wiki | bandwidth efficient] to the point that Fossil can be used comfortably over dial-up or over the exceedingly slow Wifi on airliners. 5. <b>Simple Server Setup</b> - No server is required, but if you want to set one up, Fossil supports [./server/ | several different server configurations] including CGI, SCGI, and direct HTTP. You can also easily set up your Fossil repository to automatically [./mirrortogithub.md | mirror content on GitHub]. 6. <b>Autosync</b> - Fossil supports [./concepts.wiki#workflow | "autosync" mode] which helps to keep projects moving forward by reducing the amount of needless [./branching.wiki | forking and merging] often associated with distributed projects. 7. <b>Robust & Reliable</b> - Fossil stores content using an [./fileformat.wiki | enduring file format] in an SQLite database so that transactions are atomic even if interrupted by a power loss or system crash. Automatic [./selfcheck.wiki | self-checks] verify that all aspects of the repository are consistent prior to each commit. 8. <b>Free and Open-Source</b> - Uses the [../COPYRIGHT-BSD2.txt|2-clause BSD license]. <hr> <h3>[/timeline?t=release|Latest Release]: 2.11.1 (2020-06-08)</h3> * [/uv/download.html|Download] * [./changes.wiki#v2_11|Change Summary] <hr> <h3>Quick Start</h3> 1.

And since most other version control systems will also import/export from Git, that means that you can import/export a Fossil repository to most version control systems using Git as an intermediary. <h2>Git → Fossil</h2> To import a Git repository into Fossil, run commands like this: <blockquote><pre> cd git-repo git fast-export --all | fossil import --git new-repo.fossil </pre></blockquote> In other words, simply pipe the output of the "git fast-export" command into the "fossil import --git" command. The 3rd argument to the "fossil import" command is the name of a new Fossil repository that is created to hold the Git content. The --git option is not actually required. The git-fast-export file format is currently the only VCS interchange format that Fossil understands. But future versions of Fossil might be enhanced to understand other VCS interchange formats, and so for compatibility, use of the --git option is recommended. <h2>Fossil → Git</h2> To convert a Fossil repository into a Git repository, run commands like this: <blockquote><pre> git init new-repo cd new-repo fossil export --git ../repo.fossil | git fast-import </pre></blockquote> In other words, create a new Git repository, then pipe the output from the "fossil export --git" command into the "git fast-import" command. Note that the "fossil export --git" command only exports the versioned files. Tickets and wiki and events are not exported, since Git does not understand those concepts. As with the "import" command, the --git option is not required since the git-fast-export file format is currently the only VCS interchange format that Fossil will generate. However, future versions of Fossil might add the ability to generate other VCS interchange formats, and so for compatibility, the use of the --git option recommended. <h2>Mirror A Fossil Repository In Git</h2> Fossil version 2.9 and later supports a simple mechanism for doing a Git or [./mirrortogithub.md|GitHub mirror of a Fossil repository]. See that separate document for details. Fossil is self-hosting, but a [https://github.com/drhsqlite/fossil-mirror|GitHub mirror of Fossil] is available as a proof-of-concept. <h2>Bidirectional Synchronization</h2> Fossil also has the ability to synchronize with a Git repository via repeated imports and/or exports. To do this, it uses marks files to store a record of artifacts which are known by both Git and Fossil to exist at a given point in time. To illustrate, consider the example of a remote Fossil repository that a user wants to import into a local Git repository. First, the user would clone the remote repository and import it into a new Git repository: <blockquote><pre> fossil clone /path/to/remote/repo.fossil repo.fossil mkdir repo cd repo fossil open ../repo.fossil mkdir ../repo.git cd ../repo.git git init . fossil export --git --export-marks ../repo/fossil.marks \ ../repo.fossil | git fast-import \ --export-marks=../repo/git.marks </pre></blockquote> Once the import has completed, the user would need to <tt>git checkout trunk</tt>. At any point after this, new changes can be imported from the remote Fossil repository: <blockquote><pre> cd ../repo fossil pull cd ../repo.git fossil export --git --import-marks ../repo/fossil.marks \ --export-marks ../repo/fossil.marks \ ../repo.fossil | git fast-import \ --import-marks=../repo/git.marks \ --export-marks=../repo/git.marks </pre></blockquote> Changes in the Git repository can be exported to the Fossil repository and then pushed to the remote: <blockquote><pre> git fast-export --import-marks=../repo/git.marks \ --export-marks=../repo/git.marks --all | fossil import --git \ --incremental --import-marks ../repo/fossil.marks \ --export-marks ../repo/fossil.marks ../repo.fossil cd ../repo fossil push </pre></blockquote> |

The intent is that the UI be usable with JavaScript entirely disabled. In every place where Fossil uses JavaScript, it is an enhancement to provided functionality, and there is always another way to accomplish a given end without using JavaScript. This is not to say that Fossil’s fall-backs for such cases are always as elegant and functional as a no-JS purist might wish. That is simply because [the vast majority of web users run with JS enabled](#stats), and a minority of those run with some kind of conditional JavaScript blocking in place. Fossil’s active developers do not deviate from that norm enough that we have many no-JS purists among us, so the no-JS case doesn’t get as much attention as some might want. We do [accept code contributions][cg], and we are philosophically in favor of graceful fall-backs, so you are welcome to appoint yourself the position of no-JS czar for the Fossil project! Evil is in actions, not in nouns, so we do not believe JavaScript *can* be evil. It is an active technology, but the actions that matter here are those of writing the code and checking it into the Fossil project repository. None of the JavaScript code in Fossil is evil, a fact we enforce by being careful about who we give check-in rights on the repository to and by policing what code does get contributed. The Fossil project does not accept non-trivial outside contributions. We think it’s better to ask not whether Fossil requires JavaScript but whether Fossil uses JavaScript *well*, so that [you can decide](#block) to block or allow Fossil’s use of JavaScript. [cg]: ./contribute.wiki ## <a id="block"></a>Blocking JavaScript Rather than either block JavaScript wholesale or give up on blocking JavaScript entirely, we recommend that you use tools like [NoScript][ns] or [uBlock Origin][ub] to selectively block problematic uses of JavaScript so the rest of the web can use the technology productively, as it was intended. There are doubtless other useful tools of this sort; we recommend only these two due to our limited experience, not out of any wish to exclude other tools. The primary difference between these two for our purposes is that NoScript lets you select scripts to run on a page on a case-by-case basis, whereas uBlock Origin delegates those choices to a group of motivated volunteers who maintain whitelists and blacklists to control all of this; you can then override UBO’s stock rules as needed. [ns]: https://noscript.net/ [ub]: https://github.com/gorhill/uBlock/ ## <a id="stats"></a>How Many Users Run with JavaScript Disabled Anyway? There are several studies that have directly measured the web audience to answer this question: * [What percentage of browsers with javascript disabled?][s1] * [How many people are missing out on JavaScript enhancement?][s2] * [Just how many web users really disable cookies or JavaScript?][s3] Our sense of this data is that only about 0.2% of web users had JavaScript disabled while participating in these studies. The Fossil user community is not typical of the wider web, but if we were able to comprehensively survey our users, we’d expect to find an interesting dichotomy. Because Fossil is targeted at software developers, who in turn are more likely to be power-users, we’d expect to find Fossil users to be more in favor of some amount of JavaScript blocking than the average web user. Yet, we’d also expect to find that our user base has a disproportionately high number who run [powerful conditional blocking plugins](#block) in their browsers, rather than block JS entirely. We suspect that between these two forces, the number of no-JS purists among Fossil’s user base is still a tiny minority.

Every bit of JavaScript served by the stock version of Fossil was written specifically for the Fossil project and is stored [in its code repository](https://fossil-scm.org/fossil/file). Therefore, if you want to hack on the JavaScript code served by Fossil and mechanisms like [skin editing][cs] don’t suffice for your purposes, you can hack on the JavaScript in your local instance directly, just as you can hack on its C, SQL, and Tcl code. Fossil is free and open source software, under [a single license][2cbsd]. [2cbsd]: https://fossil-scm.org/home/doc/trunk/COPYRIGHT-BSD2.txt [cs]: ./customskin.md ## <a id="snoop"></a>Fossil Does Not Snoop On You There is no tracking or other snooping technology in Fossil other than that necessary for basic security, such as IP address logging on check-ins. (This is in part why we have no [comprehensive user statistics](#stats)!) Fossil attempts to set two cookies on all web clients: a login session cookie and a display preferences cookie. These cookies are restricted to the Fossil instance, so even this limited data cannot leak between Fossil instances or into other web sites. There is some server-side event logging, but that is done entirely without JavaScript, so it’s off-topic here. ## <a id="uses"></a>Places Where Fossil’s Web UI Uses JavaScript The remainder of this document will explain how Fossil currently uses JavaScript and what it does when these uses are blocked. ### <a id="timeline"></a>Timeline Graph Fossil’s [web timeline][wt] uses JavaScript to render the graph connecting the visible check-ins to each other, so you can visualize parent/child relationships, merge actions, etc. We’re not sure it’s even possible to render this in static HTML, even with the aid of SVG, due to the vagaries of web layout among browser engines, screen sizes, etc. Fossil also uses JavaScript to handle clicks on the graph nodes to allow diffs between versions, to display tooltips showing local context, etc. _Graceful Fallback:_ When JavaScript is disabled, this column of the timeline simply collapses to zero width. All of the information you can get from the timeline can be retrieved from Fossil in other ways not using JavaScript: the “`fossil timeline`†command, the “`fossil info`†command, by clicking around within the web UI, etc. _Potential Workaround:_ The timeline could be enhanced with `<noscript>` tags that replace the graph with a column of checkboxes that control what a series of form submit buttons do when clicked, replicating the current JS-based features of the graph using client-server round-trips. For example, you could click two of those checkboxes and then a button labeled “Diff Selected†to replicate the current “click two nodes to diff them†feature. [wt]: https://fossil-scm.org/fossil/timeline ### <a id="wedit"></a>WYSIWYG Wiki Editor The Admin → Wiki → “Enable WYSIWYG Wiki Editing†toggle switches the default plaintext editor for [Fossil wiki][fw] documents to one that works like a basic word processor. This feature requires JavaScript in order to react to editor button clicks like the “**B**†button, meaning “make \[selected\] text boldface.†There is no standard WYSIWYG editor component in browsers, doubtless because it’s relatively straightforward to create one using JavaScript. _Graceful Fallback:_ Edit your wiki documents in the default plain text wiki editor. Fossil’s wiki and Markdown language processors were designed to be edited that way. [fw]: ./wikitheory.wiki ### <a id="ln"></a>Line Numbering When viewing source files, Fossil offers to show line numbers in some cases. Toggling them on and off is currently handled in JavaScript. ([Example][mainc].) _Workaround:_ Edit the URL to give the “`ln`†query parameter per [the `/file` docs](/help?cmd=/file), or provide a patch to reload the page with this parameter included/excluded to implement the toggle via a server round-trip. [mainc]: https://fossil-scm.org/fossil/artifact?ln&name=87d67e745 ### <a id="sxsdiff"></a>Side-by-Side Diff Mode The default “diff†view is a side-by-side mode. If either of the boxes of output — the “from†and “to†versions of the repo contents for that check-in — requires a horizontal scroll bar given the box content, font size, browser window width, etc., both boxes will usually end up needing to scroll since they should contain roughly similar content. Fossil therefore scrolls both boxes when you drag the scroll bar on one because if you want to examine part of a line scrolled out of the HTML element in one box, you probably want to examine the same point on that line in the other box. _Graceful Fallback:_ Manually scroll both boxes to sync their views. ### <a id="sort"></a>Table Sorting On pages showing a data table, the column headers may be clickable to do a client-side sort of the data on that column. _Potential Workaround:_ This feature could be enhanced to do the sort on the server side using a page re-load. ### <a id="tree"></a>File Browser Tree View The [file browser’s tree view mode][tv] uses JavaScript to handle clicks on folders so they fold and unfold without needing to reload the entire page. _Graceful Fallback:_ When JavaScript is disabled, clicks on folders reload the page showing the folder contents instead. You then have to use the browser’s Back button to return to the higher folder level. [tv]: https://www.fossil-scm.org/fossil/dir?type=tree ### <a id="hash"></a>Version Hashes In several places where the Fossil web UI shows a check-in hash or similar, hovering over that check-in shows a tooltip with details about the type of artifact the hash refers to and allows you to click to copy the hash to the clipboard. _Graceful Fallback:_ When JavaScript is disabled, these tooltips simply don’t appear. You can then select and copy the hash using your browser, make “`fossil info`†queries on those hashes, etc. ### <a id="bots"></a>Anti-Bot Defenses Fossil has [anti-bot defenses][abd], and it has some JavaScript code that, if run, can drop some of these defenses if it decides a given page was loaded on behalf of a human, rather than a bot. _Graceful Fallback:_ You can use Fossil’s anonymous login feature to convince the remote Fossil instance that you are not a bot. Coupled with [the Fossil user capability system][caps], you can restore all functionality that Fossil’s anti-bot defenses deny to random web clients by default. [abd]: ./antibot.wiki [caps]: ./caps/ ### <a id="hbm"></a>Hamburger Menu The default skin includes a “hamburger menu†(☰) which uses JavaScript to show a simplified version of the Fossil UI site map using an animated-in dropdown. _Graceful Fallback:_ Clicking the hamburger menu button with JavaScript disabled will take you to the `/sitemap` page instead of showing a simplified version of that page’s content in a drop-down. _Workaround:_ You can remove this button by [editing the skin][cs] header. ### <a id="clock"></a>Clock Some stock Fossil skins include JavaScript-based features such as the current time of day. The Xekri skin includes this in its header, for example. A clock feature requires JavaScript not only to get the time and update inline on the page once a minute, but also so it displays *in the local time zone.* Since none of this code provides a necessary Fossil feature, the core developers are unlikely to try to make these features work better in the absence of JavaScript. However, we are willing to study patches to make this better. For example, the wall clock displays could include the page load time in the dynamically generated HTML shipped from the remote Fossil server, so that in the absence of JavaScript, you at least get the page generation time, expressed in the server’s time zone. |

The "parent" property of file entries refers to the parent hash of that file. In the case of a merge there may be essentially an arbitrary number. The first entry in the list is the "primary" parent. The primary parent is the parent which was not pulled in via a merge operation. The ordering of remaining entries is unspecified and may even change between calls. For example: if, from branch C, we merge in A and B and then commit, then in the artifact response for that commit the hash of branch C will be in the first (primary) position, with the hashes for branches A and B in the following entries (in an unspecified, and possibly unstable, order). Note that the "uuid" and "parent" properties of the "files" entries refer to raw blob hashes, not commit (a.k.a. check-in) hashes. See also [the UUID vs. Hash discussion][uvh]. <a id="file"></a> # File Artifacts Fetches information about file artifacts. **FIXME:** the content type guessing is currently very primitive, and may (but i haven't seen this) mis-diagnose some non-binary files as binary. Fossil doesn't yet have a mechanism for mime-type mappings. **Status:** implemented 20111020 **Required permissions:** "o" **Request:** `/json/artifact/FILE_HASH` **Request options:** - `format=(raw|html|none)` (default=none). If set, the contents of the artifact are included if they are text, else they are not (JSON does not do binary). The "html" flag runs it through the wiki parser. The results of doing so are unspecified for non-embedded-doc files. The "raw" format means to return the content as-is. "none" is the same as not specifying this flag, and elides the content from the response. - DEPRECATED (use format instead): `includeContent=bool` (=false) (CLI: `--content|-c`). If true, the full content of the artifact is returned for text-only artifacts (but not for non-text artifacts). As of 20120713 this option is only inspected if "format" is not specified. **Response payload example: (CHANGED SIGNIFICANTLY ON 20120713)** ```json { "type":"file", "name":"same name specified as FILE_HASH argument", "size": 12345, // in bytes, independent of format=... "parent": "hash of parent file blob. Not set for first generation.", "checkins":[{ "name":"src/json_detail.h", "timestamp":1319058803, "comment":"...", "user":"stephan", "checkin":"d2c1ae23a90b24f6ca1d7637193a59d5ecf3e680", "branch":"json", "state":"added|modified|removed" }, ...], /* The following "content" properties are only set if format=raw|html */ "content": "file contents", "contentSize": "size of content field, in bytes. Affected by the format option!", "contentType": "text/plain", /* currently always text/plain */ "contentFormat": "html|raw" } ``` The "checkins" array lists all checkins which include this file, and a file might have different names across different branches. The size and hash, however, are the same across all checkins for a given blob. <a id="wiki"></a> # Wiki Artifacts Returns information about wiki artifacts. **Status:** implemented 20111020, fixed to return the requested version (instead of the latest) on 20120302. **Request:** `/json/artifact/WIKI_HASH` **Required permissions:** "j" **Options:** - DEPRECATED (use format instead): `bool includeContent` (=false). If true then the raw content is returned with the wiki page, else no content is returned.\ CLI: `--includeContent|-c` - The `--format` option works as for [`/json/wiki/get`](api-wiki.md#get), and if set then it implies the `includeContent` option. **Response payload example:** Currently the same as [`/json/wiki/get`](api-wiki.md#get).

It should be.) The authentication-related operations are described in this section (ordered alphabetically by operation name). The JSON API ties in to/piggybacks on fossil's existing cookie-based login mechanism, but we must also keep in mind that not all JSON-using clients support cookies. Cookie-capable clients can rely on cookies for authentication, whereas non-cookie-aware clients will need to keep track of the so-called "auth token" which is created via a login request, and pass it in with each request (either as a GET parameter or a property of the top-level POST request envelope) to prove to fossil that they are authorized to access the requested resources. For most intents and purposes, the "auth token" and the "login cookie" are the same thing (or serve the same purpose), and the auth token is in fact just the value part of the login cookie (which has a project-specific key). Note that fossil has two conventional user names which can show up in various response but do not refer to specific people: nobody and anonymous. The nobody user is anyone who is not logged in. The anonymous user is logged in but has no persistent user data (no associated user name, email address, or similar). Normally the guest (nobody) user has more access restrictions. The distinction between the two is largely historical - it is a mechanism to keep bots from following the multitudes of links generated by the HTML interface (especially the ZIP files), while allowing interested users to do so by logging in as the anonymous user (which bots have (or *had*, at the time) a harder time doing because the password is randomly generated and protected from brute-force attacks by hashing). In the JSON API, the distinction between anonymous and nobody is not expected to be as prominent as it is in the HTML interface because the reasons for the distinction don't apply in *quite* the same ways to the JSON interface. It is possible, however, that a given repo locks out guest access to, e.g. the wiki or tickets, while still allowing anonymous (logged in) access. <a id="capabilities"></a> # Capabilities (Access Rights) The "cap" request returns information about the so-called "capabilities" (access rights) of the currently logged in user. This command is basically the same as the "whoami" command, but returns capabilities in a more exanded form (same data, different representation) and does not include the authToken in the response. TODO: consider combining this and [whoami](#whoami) into a single whoami response. We don't need both. We also don't really need the permissionFlags member - the same info is already \[in a more cryptic form\] in the capabilities string. **Status:** implemented 201109xx. **Required privileges:** none **Request:** `/json/cap` In CLI mode, permissions are not used/honored, and this command will report that the caller has all permissions (which he effectively does). **Response payload example:** ```json { "userName":"json-demo", "capabilities":"hgjorxz", /* raw fossil permissions list */ "permissionFlags":{ /* Same info in a somewhat friendlier form */ "setup": false, "admin": false, "delete": false, "password": false, "query": false, "checkin": false, "checkout": true, "history": true, "clone": false, "readWiki": true, "createWiki": false, "appendWiki": false, "editWiki": false, "readTicket": true, "createTicket": false, "appendTicket": false, "editTicket": false, "attachFile": false, "createTicketReport": false, "readPrivate": false, "zip": true, "xferPrivate": false } } ``` **FIXME:** several new permissions have been added to fossil since this API was implemented. <a id="login"></a> # Login **Status:** implemented 20110915 (anonymous login 20110918) **Required privileges:** none **Request:** (see below for Anonymous user special case) - `/json/login?name=...&password=...` - `/json/login?n=...&p=...` (for symmetry with existing login mechanism) Or `POST.payload`: `{ "name": ..., "password": ...}` (POST is highly preferred because it keeps the password out of web server logs!) **Response payload example:** (structure changed 20111001) ```json { "authToken":"...", "name":"json-demo", "capabilities":"hgjorxz", "loginCookieName": "fossil-XXXXX" /*project-specific cookie name*/ /* TODO: add authTokenExpiry timestamp (cookie expiry time) */ } ``` We "should" be able to inherit fossil's `REMOTE_USER` handling without any special support, but that is untested so far. (If you happen to test this, please update this doc with (or otherwise report) your results!) The response *also* sets the conventional fossil login cookie (for clients which can make use of cookies), using fossil's existing mechanism for this. Further requests which require authentication must include the `authToken` (from the returned payload value) in the request (or it must be available via fossil's standard cookie) or access may (depending on the request) be denied. The `authToken` may optionally be set in the request envelope or as a GET parameter, and it *must* be given if the request requires restricted access to a resource. e.g. if reading tickets is disabled for the guest user then all non-guest users must send authentication info in their requests in order to be able to fetch ticket info. Cookie-aware clients should send the login-generated cookie with each request, in which case they do not need explicitly include the `authToken` in the JSON envelope/GET arguments. If submitted, the `authToken` is used, otherwise the cookie, if set, is used. Note that fossil uses a project-dependent cookie name in order to help thwart attacks, so there is no simple mapping of cookie *name* to auth token. That said, the cookie's *value* is also the auth token's value. > Special case: when accessing fossil over a local server instance which was started with the `--localauth` flag, the `authToken` is ignored (neither validated nor used for any form of authentication). <a id="login-anonymous"></a> ## Anonymous User Logins The Anonymous user requires special handling because he has a random password. First fetch the password and the so-called "captcha seed" via this request: `/json/anonymousPassword` It will return a payload in the form: ```json { "seed": a_32_bit_unsigned_integer, "password": "1234abcd" /*hexadecimal STRING*/ } ``` The "seed" and "password" values of the response payload must be set as the "anonymousSeed" and "password" fields (respectively) of the subsequent login request. The login request is identical to non-anonymous login except that extra "anonymousSeed" property is required. The password value *may* be time-limited, and *may* eventually become invalidated due to old age. This is unspecified. ***Potential***** (low-probability) bug regarding the seed value:** from what i hear, some unusual JSON platforms don't support full 32-bit precision. If absolutely necessary we could chop off a bit or two from the seed value (*if* it ever becomes a problem and if DRH blesses it). Or we could just make it a double. <a id="logout"></a> # Logout **Status:** implemented 20110916 **Required privileges:** none, but must be logged in **Request:** - `/json/logout?authToken=...token fetched by /login` Or: set the `authToken` property of the POST envelope (as opposed to the `POST.payload`) Or: fossil's normal cookie mechanism is the fallback for the auth token. **Response payload:** The same as the "whoami" response, containing the info for the "nobody" user. This request requires the authentication token, and subsequent logouts without an intervening login will fail with the "auth token not provided" error. In effect this request removes the login entry from the user account, making the token invalid for future requests. In HTTP mode, on success fossil's login cookie is unset by this call. <a id="whoami"></a> # Whoami This request fetches the current user's login name, capabilities, and auth token. This can be used to check whether a login is active when the client has not explicitly logged in (e.g. was logged in automatically via a pre-existing cookie). **Status:** implemented 20110922 **Required privileges:** none **Request:** `/json/whoami` **Response payload example:** ```json { "name": "nobody", "capabilities": "o", "authToken": "fossil auth token (only for logged-in users)" } ``` The reason authToken is included in the response is because it gives client-side JavaScript code a way of fetching/checking for the auth token at app startup. The token is normally sent as a cookie but parsing the cookies in the browser is tedious, and fossil has a project-dependent cookie name (which complicates parsing a bit). If client code digs the cookie out of the browser, the app still wouldn't know if the token is still valid, whereas whoami won't (or shouldn't!) return an expired auth token. If the request does not include authentication info (via the cookie, GET param, or request envelope) then the response will not contain the authToken property and the user's name will be "nobody". |

Only branches with this state are returned. CLI mode options (same semantics as HTTP equivalents), must come last on the CLI: - `-r|--range all|closed|open` - `-a` (equivalent to `-r all`) - `-c` (equivalent to `-r closed`). Only one of `-a`/`-c` may be specified, and if both are specified then which one takes precedence is unspecified. <a id="create"></a> # Create Branch **Status:** implemented 20111002 **Required privileges:** "w" **Request:** `/json/branch/create` **Request options:** - `name=string` (REQUIRED) Name of new branch - `basis=string` (default=trunk) Name of parent branch to branch from. - `bgColor=string` (default=something ugly) In `#RRGGBB` form.

Conflicts are not treated as errors because the CLI 'status' command does not treat them as such. - TODO: Info for the parent version is currently missing. - TODO: "merged with" info for the checkout is currently missing. |

If a commit hash is provided, a diff of the manifests is returned. (That should be considered a bug - we should return a combined diff in that case.) - If hashes from two different types of artifacts are given, results are unspecified. Garbage in, garbage out, and all that. - For file diffs, add the file name(s) to the response payload. |

If checkin is not set then all files from all versions of the tree are returned (but only once per file - not with complete version info for each file in all branches).\ CLI: `--checkin|-ci CHECKIN` - `name=subdirectory` name. To fetch the root directory, don't pass this option, or use an empty value or "/".\ CLI: use `--name|-n NAME` or pass it as the first argument after the `dir` subcommand. **Response payload example:** ```json { "name":"/", /* dir name */ "uuid":"ac6366218035ed62254c8d458f30801273e5d4fc", "checkin":"tip", "entries":[{ "name": "ajax", /* file name/dir name fragment */ "isDir": true, /* only set for directories */ /* The following properties are ONLY set if the 'checkin' parameter is provided. */ "uuid": "..." /*only for files, not dirs*/, "size": number, "timestamp": number },...] } ``` The checkin property is only set if the request includes it. The entry-specific uuid and size properties (e.g. `entries[0].uuid`) are only set if the checkin request property is set and they refer to the latest version of that file for the given checkin. The `isDir` property is only set on directory entries. This command does not recurse into subdirectories, though it "should be" simple enough to add the option to do so. |

And thus this command is named "g"... **Status:** implemented 20111009 **Required permissions:** "a" or "s" **Request:** `/json/g` **Response payload example:** this is a debugging-only request, and has no stable response payload structure. The result object contains all kinds of details gleaned from the fossil environment. Easter egg: this output can be added to ANY response by passing the `debugFossilG` boolean in the POST envelope or GET parameters, or as the `--json-debug-g` flag in CLI mode. This requires admin or setup privileges, though, and it is silently ignored for other users. <a id="rebuild"></a> # Rebuild Repository This request does the same as the "fossil rebuild" command, rebuilding the repo-internal structure. This is often required after upgrading the fossil binary on a system. There "are very probably" cases where calling this over HTTP will not work (e.g. if the user table has changed enough that the access rights cannot be validated without a rebuild, i.e. a chicken/egg scenario). Another consideration is that this request can take a long time to run - rebuilding the fossil repo on my laptop takes about 21 seconds, which is likely longer than the timeout set on an XHR request, meaning that the rebuild transaction will fail. It can safely be run in CLI mode, where timeouts are not normally a concern. As a preliminary benchmark: rebuilding the fossil repo (as of late 2011) takes just over 21 seconds on my 32-bit 1.6GHz netbook. That said, most repos are much smaller and rebuild in under a few seconds. **Status:** implemented 20110929 **Required privileges:** "a" **Request:** `/json/rebuild` Requires admin access rights. **Response payload:** none (response envelope `resultCode` reports failure). Potential TODO: return the amount of time it took to rebuild. <a id="result-codes"></a> # Result Code Descriptions This request returns the full list of result codes documented for Fossil's JSON API. Each result code is returned as an object containing metadata about the result code. **Status:** implemented 20111006 **Required permissions:** none **Request:** `/json/resultCodes` **Response payload example:** ```json [{ "resultCode":"FOSSIL-1000", "cSymbol":"FSL_JSON_E_GENERIC", "number":1000, "description":"Generic error" }, … many more objects with the same structure … ] ``` |

Options: - `sql=string` The SQL code to run. It is expected that it be a SELECT statement, but that is not enforced. This parameter may be set as a POST.payload property, as the POST.payload itself, GET, or as a positional parameter coming after the command name (CLI and HTTP modes, though the escaping would be unsightly in HTTP mode). - `format=string` (default="o"). "o" specifies that each result row should be in the form of key/value pairs (o=object). "a" means each row should be an array of values. **Example request:** POST to: `/json/query` ```json { "authToken": "...", "payload": { "sql": "SELECT * FROM reportfmt", "format": "o" } } ``` **Response payload example:** (assuming the above example) ``` { "columns":[ "rn", "owner", "title", "mtime", "cols", "sqlcode" ], "rows":[ { "rn":1, "owner":"drh", "title":"All Tickets", "mtime":1303870798, }, … ] } ``` The column names are provided in a separate field is because their order is guaranteed to match the order of the query columns, whereas object key/value pairs might get reordered (typically sorted by key) when travelling through different JSON implementations. In this manner, clients can e.g. be sure to render the columns in the proper (query-specified) order. When in "array" mode the "rows" results will be an array of arrays. For example, the above "rows" property would instead look like: `[ [1, "drh", "All Tickets", 1303870798, … ], … ]` Note the column *names* are never *guaranteed* to be exactly as they appear in the SQL *unless* they are qualified with an AS, e.g. `SELECT foo AS foo...`. When generating reports which need fixed column names, it is highly recommended to use an AS qualifier for every column, even if they use the same name as the column. This is the only way to guaranty that the result column names will be stable. (FYI: that behaviour comes from sqlite3, not the JSON bits, and this behaviour *has* been known to change between sqlite3 versions (so this is not just an idle threat of *potential* future incompatibility).) |

May be a symbolic branch name. - raw=bool (=false) If true, then the name is set as it is provided by the client, else it gets "sym-" prefixed to it. Do not use this unless you really know what you're doing. - `value=string` (=null) An optional value. While tags *may* have values in fossil, it is unusual for them to have a value. (This probably has some interesting uses in custom UIs.) - `propagate=bool` (=false) Sets the tag to propagate to all descendants of the given checkin. In CLI modes, the name, checkin, and value parameters may optionally be supplied as positional parameters (in that order, after the command name). In HTTP mode they may optionally be the 4th-6th path elements or specified via GET/`POST.envelope` parameters. **Response payload example:** ```json { "name":"my-tag", "value":"abc", "propagate":true, "raw":false, "appliedTo":"626ab2f3743543122cc11bc082a0603d2b5b2b1b" } ``` The `appliedTo` property is the hash of the check-in to which the tag was applied. This is the "resolved" version of the check-in name provided by the client. <a id="cancel"></a> # Cancel Tag **Status:** implemented 20111006 **Required permissions:** "i" **Request:** `/json/tag/cancel[/name[/checkin]]` **Request options:** - `name=string` The tag name. May optionally be provided as the 4th path element. - `checkin=string` The checkin to untag. May be a symbolic branch name. May optionally be provided as the 5th path element. In CLI modes, the name and checkin parameters may optionally be supplied as positional parameters (in that order, after the command name) or using the `-name NAME` and `-checkin NAME` options. In HTTP mode they may optionally be the 4th and 5th path elements. **Response payload:** none (resultCode indicates failure) <a id="find"></a> # Find Tag Fetches information about artifacts having a particular tag. Achtung: the output of this response is based on the HTML-mode implementation, but it's not yet certain that it's exactly what we want for JSON mode. The request options and response format may change. **Status:** implemented 20111006 **Required permissions:** "o" **Request:** `/json/tag/find[/tagName]` The response format differs somewhat depending on the options: - `name=string` The tag name to search for. Can optionally be the 3rd path element. - `limit=int` (defalt=0) Limits the number of results (0=no limit). Since they are ordered from oldest to newest, the newest N results will be returned. - `type=string` (default=`*`) Searches only for the given type of artifact (using fossil's conventional type naming: ci, e, t, w. - `raw=bool` (=false) If enabled, the response is an array of hashes of the requested artifact type; otherwise, it is an array of higher-level objects. If this is true, the "name" property is interpretted as-is. If it is false, the name is automatically prepended with "sym-" (meaning a branch). (FIXME: the current semantics are confusing and hard to remember. Re-do them.) **Response payload example, in RAW mode: (expect this format to change at some point!)** ```json { "name":"sym-trunk" "raw":true, "type":"*", "limit":2, "artifacts":[ "a28c83647dfa805f05f3204a7e146eb1f0d90505", "dbda8d6ce9ddf01a16f6c81db2883f546298efb7" ] } ``` Very likely todo: return more information with that (at least the artifact type and timestamp). Once the `/json/artifact` family of bits is finished we could use that to return artifact-type-dependent values here. **Response payload example, in non-raw mode:** ``` { "name":"trunk", "raw":false, "type":"*", "limit":1, "artifacts":[{ "uuid":"4b0f813b8c59ac8f7fbbe33c0a369acc65407841", "timestamp":1317833899, "comment":"fixed [fc825dcf52]", "user":"ron", "eventType":"checkin" }] } ``` <a id="list"></a> # List Tags **Status:** implemented 20111006 **Required permissions:** "o" **Request:** `/json/tag/list[/checkinName]` Potential fixme: we probably have too many different response formats here. We should probably break this into multiple subcommands. The response format differs somewhat depending on the options: - `checkin=string` Lists the tags only for the given CHECKIN (can be a branch name). If set, includeTickets is ignored (meaningless in this combination). This option can be set as either a GET/`POST.payload` option, as the last element of the request path, e.g. `/json/tag/list/MYBRANCH` *or* with `POST.payload` set to a string value. - `raw=bool` (default=false) uses "raw" tag names - `includeTickets=bool` (default=false) Determines whether `tkt-` tags are included. There is one of these for each ticket, so there can be many of them (over 900 in the main fossil repo as of this writing). **Response format when raw=false and no checkin is specified:** ```json { "raw":false, "includeTickets":false, "tags":[ "bgcolor", "branch", "closed", …all tag names... ] } ``` Enabling the `raw` option will leave the internal `sym-` prefix on tags which have them but will not change the structure. If `includeTickets` is true then `tkt-` entries (possibly very many!) will be included in the output, else they are elided. **General notes:** The `tags` property will be null if there are no tags, every non-empty repo has at least one tag (for the trunk branch). **Response format when raw=false and checkin is specified:** ```json { "raw":false, "tags":{ "json":null, "json-multitag-test":null } } ``` The `null`s there are the tag values (most tags don't have values). If `raw=true` then the tags property changes slightly: ```json { "raw":true, "tags":{ "branch":"json", "sym-json":null, "sym-json-multitag-test":null } } ``` TODO?: change the tag values to objects in the form `{value:..., tipUuid:string, propagating:bool}`. |

That means that we cannot return a standard set of column names here. Fossil requires certain column naming conventions for purposes of styling the HTML interface, e.g. the "\#" column is always the uuid of the record and "bgcolor" (note the different casing than bgColor used throughout the rest of this API!) has a specific meaning to the HTML report browser. Fossil also allows the tickets to be extended with client-specified fields, so we cannot generically make these results fit into the API-wide naming scheme. Full details are here: [](/doc/trunk/www/custom_ticket.wiki) and: [](/rptsql?rn=1) (That one may require non-default permission.) |

The response payload differs for each artifact type, and the current structures are almost certainly not "final" (e.g. we are still undecided on how/whether to handle artifact links within commit messages and whatnot). By default the entries are returned in chronological order from newest to oldest, but some options might change that. FIXME (20120623): we have some inconsistent `type` vs. `eventType` in the result sets. `type` is the current preferred choice (and it seems unlikely that `eventType` is actually used in any client code). We don't actually need either one (but a use for `type` is easily envisioned), and we may get rid of both. **Common request options (via CLI, GET or POST.payload):** - `limit=integer` limits the number of entries in the response. Default is unspecified (but is "quite possibly 20 or so"). A limit value of 0 disables any limit, fetching all entries (which can take a really long time and might overload clients which have very limited memory).\ CLI mode: `--limit|-n #` - `after="YYYY-MM-DD[ HH:mm:ss]"` limits the search to items on or after the given date string. Reverses the normal timeline sort order. Alias: "a". Only one of "after" or "before" can be used, and if both are specified then which one takes precedence is unspecified.\ CLI mode: `--after|-a "DATE[ TIME]"` - `before="YYYY-MM-DD[ HH:mm:ss]"` limits the search to items on or before the given date string.\ CLI mode: `--before|-b "DATE[ TIME]" - TODOs, still to be ported from the HTML-mode timeline: - circa=DATETIME - tag=string - related=tag name - string=search string <a id="branch"></a> # Branch Timeline **Status:** partially implemented but undocumented because the utility of the current impl is under question. It also doesn't understand most of the common timeline options. <a id="checkin"></a> # Checkin Timeline **Status:** implemented 201109xx **Required privileges:** "o" **Request:** `/json/timeline/checkin` **Response payload example:** ```json { "limit": number, /* if not set, all records are returned */ "timeline":[{ "uuid":"be700e84336941ef1bcd08d676310b75b9070f43", "timestamp":1317094090, "comment":"Added /json/timeline/ci showFiles to ajax test page.", "user":"stephan", "isLeaf":true, "bgColor":null, /* not quite sure why this is null? */ "type":"ci", "parents": ["primary parent hash", "...other parent hashes"], "tags":["json"], "files":[{ "name":"ajax/index.html", "uuid":"9f00773a94cea6191dc3289aa24c0811b6d0d8fe", "parent":"50e337c33c27529e08a7037a8679fb84b976ad0b", "state":"modified" }] },...] } ``` (Achtung: the `parents` property was called `prevUuid` prior to 20120316.) The `parents` property lists the checkins which were parents of this commit. The first entry in the array is the "primary parent" - the one which was not involved in a merge with the child. **Request options:** - `files=bool` toggles the addition of a "files" array property which contains objects describing the files changed by the commit, including their hash, previous hash, and state change type (modified, added, or removed). ([“uuid†here means hash][uvh])\ CLI mode: `--show-files|-f` - `tag|branch=string` selects only entries with the given tag or "close to" the given branch. Only one of these may be specified and if both are specified, which one takes precedence is unspecified. If the given tag/branch does not exist, an error response is generated. The difference between the two is subtle - tag filters only on the given tag (analog to the HTML interface's "r" option) whereas branch can also return entries from other branches which were merged into the requested branch (analog to the HTML interface's "b" option). If one of these is specified, the response payload will contain a "tag" *or* "branch" property with the tag/branch name given by the client. <a id="technote"></a> # Technote (formerly Event) Timeline **Status:** implemented 20180803 **Required privileges:** "j" **Request:** - `/json/timeline/technote` - DEPRECATED: `/json/timeline/event` (technotes were formerly called `events`) **Response payload example:** ```json { "limit": number, /* if not set, all records are returned */ "timeline":[{ "name":"8d18bf27e9f9ff8b9017edd55afc35701407d418", "uuid":"b23962c88c123924a77fd663e91af094780d920a", "timestamp":1478376113, "comment":"Style update due to [8d880f0bb4]", "user":"andygoth", "eventType":"e" },...] } ``` The `uuid` of each entry can be passed to `/json/artifact` to fetch the raw event content. <a id="ticket"></a> # Ticket Timeline **Status:** implemented 201109xx **Required privileges:** "r" or "o" **Request:** `/json/timeline/ticket` **Response payload example:** ```json { "limit": number, /* if not set, all records are returned */ "timeline":[{ "uuid":"5065a5da060e181da49a618f8ae5dc245215e95b", "timestamp":1316511322, "user":"stephan", "eventType":"t", "comment":"Ticket [b64435dba9] <i>How to...</i>", "briefComment":"Ticket [b64435dba9]: 2 changes", "ticketUuid":"b64435dba9cceb709bd54fbc5883884d73f93491" },...] } ``` **Notice that there are two [hashes][uvh] for tickets** - `uuid` is the change hash and `ticketUuid` is the actual ticket’s hash. This is an unfortunate discrepancy vis-a-vis the other timeline entries, which only have one hash. We may want to swap `uuid` to mean the ticket hash and change `uuid` to `commitHash`. <a id="wiki"></a> # Wiki Timeline **Status:** implemented 201109xx **Required privileges:** "j" or "o" **Requests:** - `/json/timeline/wiki` - `/json/wiki/timeline` (alias) **Response payload example:** ```json { "limit": number, /* if not set, all records are returned */ "timeline":[{ "uuid":"4b2026f06eb48eaf187209fcb05ba5438c3b0ef0", "timestamp":1331351121, "comment":"Changes to wiki page [Page3]", "user":"stephan", "eventType":"w" },...] } ``` The `uuid` of each entry can be passed to `/json/artifact` or `/json/wiki/get?uuid=...` to fetch the raw page and the hash of the parent version.

GET/CLI parameters take precedence over those in `POST.payload`, the intention being to use an input file as a template and overriding the template's defaults via the CLI. The options include: - `name=string` Specifies the user name to change. When changing a user's name, the current uid and the new name must be specified.\ **Achtung:** due to fossil-internal ambiguity in the handling of the "name" parameter, this parameter must come from the `POST.payload` data or it will not be recognized. In CLI mode it may be specified with the `--name` flag. - `uid=int` Specifies the uid to change. At least one of uid or name are required. A uid of -1 means to create a new user, in which case the name must be provided. - `password=string` Optionally changes the user's password. When renaming existing or creating new users, be sure to always provide a new password because any old password hash is invalidated by the name change. - `info=string` Optionally changes the user's info field. - `capabilities=string` Optionally changes the user's capabilities field. - `forceLogout=bool` (=false, or true when renaming) Optionally clears any current login info for the current user, which will invalidate any active session. Requires 'a' or 's' privileges. Intended to be used when disabling a user account, to ensure that any open session is invalidated. When a user is renamed this option is implied (and cannot be disabled) because renaming invalidates any currently stored auth token (because the old name is part of the hash equation). Fields which are not provided in the request will not be modified. Non-admin/setup users cannot edit other users and may only change their own data if they have the 'p' (password) privilege. As of 20120217, users who do not have the setup privilege may neither change the setup privilege for any user nor edit another user who has that privilege. That is, only users with setup access may propagate or remove setup status and accounts with the setup privilege may only be edited by themselves and other setup users. **Response payload:** Same as user/get, using the new/saved state of the modified user. Example usage from the command line: ```console $ fossil json user save --name drh --password sqlite3 \ --capabilities "as" --info "DRH" $ fossil json user save --uid 1 --name richard \ --password fossil \ --info "Previously known as drh" ``` **Warnings:** - When creating a new user or renaming a user, if no (new) password is specified in the save request then the user will not be able to log in because the previous password (for existing users) is hashed against the old name. - Renaming a user invalidates any active login token because his old name is a part of the hash. i.e. the user must log back in with the new name after being renamed. **TODOs:** - Login group support. |

Added 20120219. - `glob=wildcard` string (default=`*`). If set, only page names matching the given wildcard are returned. Added 20120325.\ CLI: `--glob|-g STRING` - `like=SQL LIKE string` (default=`%`). If set, only page names matching the given SQL LIKE string are returned. Note that this match is case-INsensitive. If both glob and like are given then only one will work and which one takes precedence is unspecified. Added 20120325.\ CLI: `--like|-l STRING` - `invert=bool` (default=false). If set to a true value, the glob/like filter has a reverse meaning (pages *not* matching the wildcard are returned). Added 20120329.\ CLI: `-i/--invert` **Response payload: format depends on "verbose" option** Non-verbose mode: ```json ["PageName1",..."PageNameN"] ``` In verbose mode: ```json [{ "name":"Apache On Windows XP", "uuid":"a7e68df71b95d35321b9d9aeec3c8068f991926c", "user":"jeffrimko", "timestamp":1310227825, "size":793 /* in bytes */ },...] ``` The verbose-mode output is the same as the [`/json/wiki/get`](#get) output, but without the content. The size property of each reflects the *byte* length of the raw (non-HTMLized) page content. **Potential TODOs:** - Allow specifying (in the request) a list/array of names, as opposed to listing all pages. The page count is rarely very high, though, so an "overload" is very unlikely. (i have one wiki with about 47 pages in it.) <a id="get"></a> # Fetch a Page Fetches a single wiki page, including content and significant metadata. **Status:** implemented 20110922, but response format may change. **Required privileges:** "j" or "o" **Request:** - GET: `/json/wiki/get?name=PageName` - GET: `/json/wiki/get/PageName` - POST: `/json/wiki/get` with page name as `POST.payload` or `POST.payload.name`. **Response payload example:** ```json { "name": "Fossil", "uuid": "...hex string...", "parent": "uuid of parent (not set for first version of page)", "user": "anonymous", "timestamp": 1286143975, "size": 1906, /* In bytes, not UTF8 characters! Affected by format option! */ "content": "..." } ``` **FIXME:** it's missing the mimetype (that support was added to fossil after this was implemented). If given no page to load, or if asked to get a page which does not exist, an error response is generated (a usage- or resource-not-found error, respectively). **Options (via CLI/GET/`POST.payload`):** - `name=string`. The page to fetch. The latest version is fetched unless the uuid paramter is supplied (in which case name is ignored). \ CLI: `--name|-n string`\ Optionally, the name may be the 4th positional argument/request path element. - `uuid=string`. Fetches a specific version. The name parameter is ignored when this is specified.\ CLI: `--uid|-u string` - `format=string ("raw"|"html"|"none")` (default="raw"). Specifies the format of the "content" payload value.\ CLI: `--format|-f string` \ The "none" format means to return no content. In that case the size refers to the same size as the "raw" format. **TODOs:** - Support passing an array of names in the request (and change response to return an array). <a id="create-save"></a> # Create or Save Page **Status:** implemented 20110922. **Required privileges:** "k" (save) or "f" (create) **Request:** - `/json/wiki/create` - `/json/wiki/save` These work only in HTTP mode, not CLI mode. (FIXME: now that we can simulate POST from a file, these could be used in CLI mode.) The semantic differences between save and create are: - Save will fail if the page doesn't already exist whereas create will fail if it does. The createIfNotExists option (described below) can be used to create new pages using the save operation. - The content property is optional for the create request, whereas it is required to be a string for save requests (but it *may* be an empty string). This requirement for save is *almost* arbitrary, and is intended to prevent accidental erasing of existing page content via API misuse. **Response payload example:** The same as for [`/json/wiki/get`](#get) but the page content is not included in the response (only the metadata). **Request options** (via GET or `POST.payload` object): - `name=string` specifies the page name. - `content=string` is the body text.\ Content is required for save (unless `createIfNotExists` is true *and* the page does not exist), optional for create. It *may* be an empty string. - Save (not create) supports a `createIfNotExists` boolean option which makes it a functional superset of the create/save features. i.e. it will create if needed, else it will update. If createIfNotExists is false (the default) then save will fail if given a page name which does not refer to an existing page. - **TODO:** add `commitMessage` string property. The fossil internals don't have a way to do this at the moment (they can as of late 2019). Since fossil wiki commits have always had the same default commit message, this is not a high-priority addition. See:\ [](/doc/trunk/www/fileformat.wiki#wikichng) - **Potential TODO:** we *could* optionally also support multi-page saving using an array of pages in the request payload:\ `[… page objects … ]` <a id="diffs"></a> # Wiki Diffs **Status:** implemented 20120304 **Required privileges:** "h" **Request:** - `/json/wiki/diff[/version1_UUID/version2_UUID]` **Response payload example:** ```json { "v1":"e32ccdcda59e930c77c1e01cebace5d71253f621", "v2":"e15992f475760cdf3a9564d8f88cacb659ab4b07", "diff":"@@ -1,4 +1,9 @@...<SNIP>..." } ``` **Options:** - `v1=uuid` and `v2=uuid` specify the two versions to diff, and are required parameters. They may optionally be specified as the two URL/CLI parameters following the "diff" sub-command/path. This command does not verify that both UUIDs actually refer to the same page name, but do verify that they refer to wiki content. Trivia: passing the same UUIDs to the `/json/diff` command will produce very different results - that one diffs the manifests of the commits. **TODOs:** - Add options for changing the format of the diff, e.g. side-by-side and enabling the HTML markup supported by the main fossil HTML GUI. - Potentially do a name comparison to verify that the diff is against the same page. That said, when "renaming" pages it might be useful to diff two different pages. <a id="preview"></a> # Preview **Status:** implemented 20120310 **Required privileges:** "k" (to limit its use to only those who can edit wiki pages). This limitation is up for debate/reconsideration. **Request:** - `/json/wiki/preview` This command wiki-processes arbitrary text sent from the client. To help curb potential abuse, its use is restricted to those with "k" access rights. The `POST.payload` property must be a string containing Fossil wiki markup. The response payload is also a string, but contains the HTML-processed form of the string. Whether or not "all HTML" is allowed depends on site-level configuration options, and that changes how the input is processed. Note that the links in the generated page are for the HTML interface, and will not work as-is for arbitrary JSON clients. In order to integrate the parsed content with JSON-based clients the HTML will probably need to be post-processed, e.g. using jQuery to fish out the links and re-map wiki page links to a JSON-capable page handler. **TODO**: Update this to accept the other two wiki formats (which didn't exist when this API was implemented): markdown and plain text (which gets HTML-ized for preview purposes). That requires changing the payload to an object, perhaps simply submitting the same thing as `/json/save`. There's no reason we can't support both call forms. <a id="todo"></a> # Notes and TODOs - When server-parsing the wiki content, the generated intra-wiki/intra-site links will only be useful in the context of the original fossil UI (or a work-alike), not arbitrary JSON client apps.

`https://..../timeline/json` - `/timeline?format=json` - `/timeline?json=1` - `/timeline.json` - `/json/timeline?...options...` The API settled on the `/json/...` convention, primarily because it simplifies dispatching and argument-handling logic compared to the `/[.../]foo.json` approach. Using `/json/...` allows us to unify that logic for all JSON sub-commands, for both CLI and HTTP modes. <a id="http-post"></a> # HTTP Post Requests Certain requests, mainly things like editing checkin messages and committing new files entirely, require POST data. This is fundamentally very simple to do - clients post plain/unencoded JSON using a common wrapper envelope which contains the request-specific data to submit as well as some request-independent information (like authentication data). <a id="request-envelope"></a> ## POST Request Envelope POST requests are sent to the same URL as their GET counterpart (if any, else their own path), and are sent as plain-text/unencoded JSON wrapped in a common request envelope with the following properties: - `requestId`: Optional arbitrary JSON value, not used by fossil, but returned as-is in responses. - `command`: Provides a secondary mechanism for specifying which JSON command should be run. A request path of /json/foo/bar is equivalent to a request with path=/json and command=foo/bar. Note that subpaths do not work this way. e.g. path=/json/foo, command=bar will not work, but path=/json, command=foo/bar will. This option is particularly useful when generating JSON for piping in to CLI mode, but it also has some response-dispatching uses on the client side. - `authToken`: Authentication token. Created by a login request. Determines what access rights the user has, and any given request may require specific rights. In principle this is required by any request which needs non-guest privileges, but cookie-aware clients do not manually need to track this (it is managed as a cookie by the agent/browser). - Note that when accessing fossil over a local server instance which was started with the `--localauth` flag, the `authToken` will be ignored and need not be sent with any requests. The user will automatically be given full privileges, as if they were using CLI mode. - `payload`: Command-specific parameters. Most can optionally come in via GET parameters, but those taking complex structures expect them to be placed here. - `indent`: Optionally specifies indentation for the output. 0=no indention. 1=a single TAB character for each level of indentation. >1 means that many spaces per level. e.g. indent=7 means to indent 7 spaces per object/array depth level. cson also supports other flags for fine-tuning the output spacing, and adding them to this interface might be interesting at some point. e.g. whether or not to add a newline to the output. CLI mode adds extra indentation by default, whereas CGI/server modes produce unindented output by default. - `jsonp`: Optional String (client function name). Requests which include this will be returned with `Content-Type application/javascript` and will be wrapped up in a function call using the given name. e.g. if `jsonp=foo` then the result would look like:\ `foo( {...the response envelope...} )` The API allows most of those (normally all but the payload) to come in as either GET parameters or properties of the top-level POSTed request JSON envelope, with GET taking priority over POST. (Reminder to self: we could potentially also use values from cookies. Fossil currently only uses 1 cookie (the login token), and i'd prefer to keep it that way.) POST requests without such an envelope will be rejected, generating a Fossil/JSON error response (as opposed to an HTTP error response). GET requests, by definition, never have an envelope. POSTed client requests *must* send a Content-Type header of either `application/json` , `application/javascript`, or `text/plain`, or the JSON-handling code will never see the POST data. The POST handler optimistically assumes that type `text/plain` "might be JSON", since `application/json` is a newer convention which many existing clients do not use (as of the time these docs were written, back in 2011). ## POST Envelope vs. `POST.payload` When this document refers to POST data, it is referring to top-level object in JSON-format POSTed input data. When we say `POST.payload` we refer to the "payload" property of the POST data. While fossil's core handles *form-urlencoded* POST data, if such data is sent in then parsing it as JSON cannot succeed, which means that (at worst) the JSON-mode bits will "not see" any POST data. Data POSTed to the JSON API must be sent non-form-urlencoded (i.e. as plain text). Framework-level configuration options are always set via the top-level POST envelope object or GET parameters. Request-specific options are set either in `POST.payload` or GET parameters (though the former is required in some cases). Here is an example which demonstrates the possibly not-so-obvious difference between the two types of options (framework vs. request-specific): ```json { "requestId":"my request", // standard envelope property (optional) "command": "timeline/wiki", // also standard "indent":2, // output indention is a framework-level option "payload":{ // *anything* in the payload is request-specific "limit":1 } } ``` When a given parameter is set in two places, e.g. GET and POST, or POST-from-a-file and CLI parameters, which one takes precedence depends on the concrete command handler (and may be unspecified). Most will give precedence to CLI and GET parameters, but POSTed values are technically preferred for non-string data because no additional "type guessing" or string-to-whatever conversion has to be made (GET/CLI parameters are *always* strings, even if they look like a number or boolean). <a id="request-param-types"></a> # Request Parameter Data Types When parameters are sent in the form of GET or CLI arguments, they are inherently strings. When they come in from JSON they keep their full type (boolean, number, etc.). All parameters in this API specify what *type* (or types) they must (or may) be. For strings, there is no internal conversion/interpretation needed for GET- or CLI-provided parameters, but for other types we sometimes have to convert strings to other atomic types. This section describes how those string-to-whatever conversions behave. No higher-level constructs, e.g. JSON **arrays** or **objects**, are accepted in string form. Such parameters must be set in the POST envelope or payload, as specified by the specific API. This API does not currently use any **floating-point** parameters, but does return floating-point results in a couple places. For **integer** parameters we use a conventional string-to-int algorithm and assume base 10 (analog to atoi(3)). The API may err on the side of usability when given technically invalid values. e.g. "123abc" will likely be interpreted as the integer 123. No APIs currently rely on integer parameters with more than 32 bits (signedness is call-dependent but few, if any, use negative values). **Boolean** parameters are a bit schizophrenic... In **CLI mode**, boolean flags do not have a value, per se, and thus require no string-to-bool conversion. e.g. `fossil foo -aBoolOpt -non-bool-opt value`. Those which arrive as strings via **GET parameters** treat any of the following as true: a string starting with a character in the set `[1-9tT]`. All other string values are considered to be false for this purpose. Those which are part of the **POST data** are normally (but not always - it depends on the exact context) evaluated as the equivalent of JavaScript booleans. e.g. if we have `POST.envelope.foo="f"`, and evaluate it as a JSON boolean (as opposed to a string-to-bool conversion), the result will be true because the underlying JSON API follows JavaScript semantics for any-type-to-bool conversions. As long as clients always send "proper" booleans in their POST data, the difference between GET/CLI-provided booleans should never concern them. TODO: consider changing the GET-value-to-bool semantics to match the JS semantics, for consistency (within the JSON API at least, but that might cause inconsistencies vis-a-vis the HTML interface). <a id="response-envelope"></a> # Response Envelope Every response comes in the form of a HTTP response or (in CLI mode) JSON sent to stdout. The body of the response is a JSON object following a common envelope format. The envelope has the following properties: - `fossil`: Fossil server version string. This property is basically "the official response envelope marker" - if it is set, clients can "probably safely assume" that the object indeed came from one of the Fossil/JSON APIs. This API never creates responses which do not contain this property. - `requestId`: Only set if the request contained it, and then it is echoed back to the caller as-is. This can be use to determine (client-side) which request a given response is coming in for (assuming multiple asynchronous requests are pending). In practice this generally isn’t needed because response handling tends to be done by closures associated with the original request object (at least in JavaScript code). In languages without closures it might have some use. It may be any legal JSON value - it need not be confined to a string or number. - `resultCode`: Standardized result code string in the form `FOSSIL-####`. Only error responses contain a `resultCode`. - `resultText`: Possibly a descriptive string, possibly empty. Supplements the resultCode, but can also be set on success responses (but normally isn't). Clients must not rely on any specific values being set here. - `payload`: Request-specific response payload (data type/structure is request-specific). The payload is never set for error responses, only for success responses (and only those which actually have a payload - not all do). - `timestamp`: Response timestamp (GMT Unix Epoch). We use seconds precision because i did not know at the time that Fossil actually records millisecond precision. - `payloadVersion`: Not initially needed, but reserved for future use in maintaining version compatibility when the format of a given response type's payload changes. If needed, the "first version" value is assumed to be 0, for semantic [near-]compatibility with the undefined value clients see when this property is not set. - `command`: Normalized form of the command being run. It consists of the "command" (non-argument) parts of the request path (or CLI positional arguments), excluding the initial "/json/" part. e.g. the "command" part of "/json/timeline/checkin?a=b" (CLI: json timeline checkin...) is "timeline/checkin" (both in CLI and HTTP modes). - `apiVersion`: Not yet used, but reserved for a numeric value which represents the JSON API's version (which can be used to determine if it has a given feature or not). This will not be implemented until it's needed. - `warnings`: Reserved for future use as a standard place to put non-fatal warnings in responses. Will be an array but the warning structure/type is not yet specified. Intended primarily as a debugging tool, and will "probably not" become part of the public client interface. - `g`: Fossil administrators (those with the "a" or "s" permissions) may set the `debugFossilG` boolean request parameter (CLI: `--json-debug-g`) to enable this property for any given response. It contains a good deal of the server-side internal state at the time the response was generated, which is often useful in debuggering problems. Trivia: it is called "g" because that's the name of fossil's internal global state object. - `procTimeMs`: For debugging only - generic clients must not rely on this property. Contains the number of milliseconds the JSON command processor needed to dispatch and process the command. TODO: move the timer into the fossil core so that we can generically time its responses and include the startup overhead in the time calculation. <a id="http-response-header"></a> # HTTP Response Headers The Content-Type HTTP header of a response will be either application/json, application/javascript, or text/plain, depending on whether or not we are in JSONP mode or (failing that) the contents of the "Accept" header sent in the request. The response type will be text/plain if it cannot figure out what to do. The response's Content-Type header *may* contain additional metadata, e.g. it might look like: application/json; charset=utf-8 Apropos UTF-8: note that JSON is, by definition, Unicode and recommends UTF-8 encoding (which is what we use). That means if your console cannot handle UTF-8 then using this API in CLI mode might (depending on the content) render garbage on your screen. <a id="cli-vs-http"></a> # CLI vs. HTTP Mode CLI (command-line interface) and HTTP modes (CGI and standalone server) are consolidated in the same implementations and behave essentially identically, with only minor exceptions. An HTTP path of `/json/foo` translates to the CLI command `fossil json foo`. CLI mode takes options in the fossil-convention forms (e.g. `--foo 3` or `-f 3`) whereas HTTP mode takes them via GET/POST data (e.g. `?foo=1`). (Note that per long-standing fossil convention CLI parameters taking a value do not use an equal sign before the value!) For example: - HTTP: `/json/timeline/wiki?after=2011-09-01&limit=3` - CLI: `fossil json timeline wiki --after 2011-09-01 --limit 3` Some commands may only work in one mode or the other (for various reasons). In CLI mode the user automatically has full setup/admin access. In HTTP mode, request-specific options can also be specified in the `POST.payload` data, and doing so actually has an advantage over specifying them as URL parameters: posting JSON data retains the full type information of the values, whereas GET-style parameters are always strings and must be explicitly type-checked/converted (which may produce unpredictable results when given invalid input). That said, oftentimes it is more convenient to pass the options via URL parameters, rather than generate the request envelope and payload required by POST requests, and the JSON API makes some extra effort to treat GET-style parameters type-equivalent to their POST counterparts. If a property appears in both GET and `POST.payload`, GET-style parameters *typically* take precedence over `POST.payload` by long-standing convention (=="PHP does it this way by default"). (That is, however, subject to eventual reversal because of the stronger type safety provided by POSTed JSON. Philosophically speaking, though, GET *should* take precedence, in the same way that CLI-provided options conventionally override app-configuration-level options.) One notable functional difference between CLI and HTTP modes is that in CLI mode error responses *might* be accompanied by a non-0 exit status (they "should" always be, but there might be cases where that does not yet happen) whereas in HTTP mode we always try to exit with code 0 to avoid generating an HTTP 500 ("internal server error"), which could keep the JSON response from being delivered. The JSON code only intentionally allows an HTTP 500 when there is a serious internal error like allocation or assertion failure. HTTP clients are expected to catch errors by evaluating the response object, not the HTTP result code. <a id="simulating-post-data"></a> # Simulating POSTed data We have a mechanism to feed request data to CLI mode via files (simulating POSTed data), as demonstrated in this example: ```console $ cat in.json { "command": "timeline/wiki", "indent":2, "payload":{"limit":1}} $ fossil json --json-input in.json # use filename - for stdin ``` The above is equivalent to: ```console $ echo '{"indent":2, "payload":{"limit":1}}' \ | fossil json timeline wiki --json-input - ``` Note that the "command" JSON parameter is only checked when no json subcommand is provided on the CLI or via the HTTP request path. Thus we cannot pass the CLI args "json timeline" in conjunction with a "command" string of "wiki" this way. ***HOWEVER...*** Much of the existing JSON code was written before the `--json-input` option was possible. Because of this, there might be some "misinteractions" when providing request-specific options via *both* CLI options and simulated POST data. Those cases will eventually be ironed out (with CLI options taking precedence). Until then, when "POSTing" data in CLI mode, for consistent/predictible results always provide any options via the JSON request data, not CLI arguments. That said, there "should not" be any blatant incompatibilities, but some routines will prefer `POST.payload` over CLI/GET arguments, so there are some minor inconsistencies across various commands with regards to which source (POST/GET/CLI) takes precedence for a given option. The precedence "should always be the same," but currently cannot be due to core fossil implementation details (the internal consolidation of GET/CLI/POST vars into a single set). <a id="json-indentation"></a> # Indentation/Formatting of JSON Output CLI mode accepts the `--indent|-I #` option to set the indention level and HTTP mode accepts `indent=#` as a GET/POST parameter. The semantics of the indention level are derived from the underlying JSON library and have the following meanings: 0 (zero) or less disables all superfluous indentation (this is the default in HTTP mode). A value of 1 uses 1 hard TAB character (ASCII 0x09) per level of indention (the default in CLI mode). Values greater than 1 use that many whitespaces (ASCII 32d) per level of indention. e.g. a value of 7 uses 7 spaces per level of indention. There is no way to specify one whitespace per level, but if you *really* want one whitespace instead of one tab (same data size) you can filter the output to globally replace ASCII 9dec (TAB) with ASCII 32dec (space). Because JSON string values *never* contain hard tabs (they are represented by `\t`) there is no chance that such a global replacement will corrupt JSON string contents - only the formatting will be affected. Potential TODO: because extraneous indention "could potentially" be used as a form DoS, the option *might* be subject to later removed from HTTP mode (in CLI it's fine). In HTTP mode no trailing newline is added to the output, whereas in CLI mode one is normally appended (exception: in JSONP mode no newline is appended, to (rather pedantically and arbitraily) allow the client to add a semicolon at the end if he likes). There is currently no option to control the newline behaviour, but the underlying JSON code supports this option, so adding it to this API is just a matter of adding the CLI/HTTP args for it. Pedantic note: internally the indention level is stored as a single byte, so giving large indention values will cause harmless numeric overflow (with only cosmetic effects), meaning, e.g., 257 will overflow to the value 1. Potential TODO: consider changing cson's indention mechanism to use a *signed* number, using negative values for tabs and positive for whitespace count (or the other way around). This would require more doc changes than code changes :/. <a id="jsonp"></a> # JSONP The API supports JSONP-style output. The caller specifies the callback name and the JSON response will be wrapped in a function call to that name. For HTTP mode pass the `jsonp=string` option (via GET or POST envelope) and for CLI use `--jsonp string`. For example, if we pass the JSONP name `myCallback` then a response will look like: ```js myCallback({...response...}) ``` Note that fossil does not evaluate the callback name itself, other than to verify that it is-a string, so "garbage in, garbage out," and all that. (Remember that CLI and GET parameters are *always* strings, even if they *look* like numbers.) <a id="result-codes"></a> # API Result Codes Result codes are strings which tell the client whether or not a given API call succeeded or failed, and if it failed *perhaps* some hint as to why it failed. The result code is available via the resultCode property of every *error* response envelope. Since having a result code value for success responses is somewhat redundant, success responses contain no resultCode property. In practice this simplifies error checking on the client side. The codes are strings in the form `FOSSIL-####`, where `####` is a 4-digit integral number, left-padded with zeros. The numbers follow these conventions: - The number 0000 is reserved for the "not an error" (OK) case. Since success responses do not contain a result code, clients won't see this value (except in documentation). - All numbers with a leading 0 are reserved for *potential* future use in reporting non-fatal warnings. - Despite *possibly* having leading zeros, the numbers are decimal, not octal. Script code which uses eval() or similar to produce integers from them may need to take that into account. - The 1000ths and 100ths places of the number describe the general category of the error, e.g. authentication- vs. database- vs. usage errors. The 100ths place is more specific than the 1000ths place, allowing two levels of sub-categorization (which "should be enough" for this purpose). This separation allows the server administrator to configure the level of granularity of error reporting. e.g. some admins consider error messages to be security-relevant and like to "dumb them down" on their way to the client, whereas developers normally want to see very specific error codes when tracking down a problem. We can offer a configuration option to "dumb down" error codes to their generic category by simply doing a modulo 100 (or 1000) against the native error code number. e.g. FOSSIL-1271 could (via a simple modulo) be reduced to FOSSIL-1200 or FOSSIL-1000, depending on the paranoia level of the sysadmin. i have tried to order the result code numbers so that a dumb-down level of 2 provides reasonably usable results without giving away too much detail to malicious clients.\ (**TODO:** `g.json.errorDetailParanoia` is used to set the default dumb-down level, but it is currently set at compile-time. It needs to be moved to a config option. We have a chicken/egg scenario with error reporting and db access there (where the config is stored).) - Once a number is assigned to a given error condition (and actually used somewhere), it may not be changed/redefined. JSON clients need to be able to rely on stable result codes in order to provide adequate error reporting to their clients, and possibly for some error recovery logic as well (i.e. to decide whether to abort or retry). The *tentative* list of result codes is shown in the following table. These numbers/ranges are "nearly arbitrarily" chosen except for the "special" value 0000. **Maintenance reminder:** these codes are defined in [`src/json_detail.h`](/finfo/src/json_detail.h) (enum `FossilJsonCodes`) and assigned default `resultText` values in [`src/json.c:json_err_cstr()`](/finfo/src/json.c). Changes there need to be reflected here (and vice versa). Also, we have assertions in place to ensure that C-side codes are in the range 1000-9999, so do not just go blindly change the numeric ranges used by the enum. **`FOSSIL-0###`: Non-error Category** - `FOSSIL-0000`: Success/not an error. Succesful responses do not contain a resultCode, so clients should never see this. - `FOSSIL-0###`: Reserved for potential future use in reporting non-fatal warnings. **`FOSSIL-1000`: Generic Errors Category** - `FOSSIL-1101`: Invalid request. Request envelope is invalid or missing. - `FOSSIL-1102`: Unknown JSON command. - `FOSSIL-1103`: Unknown/unspecified error - `FOSSIL-1104`: RE-USE - `FOSSIL-1105`: A server-side timeout was reached. (i’m not sure we can actually implement this one, though.) - `FOSSIL-1106`: Assertion failed (or would have had we continued). Note: if an `assert()` fails in CGI/server modes, the HTTP response will be code 500 (Internal Server Error). We want to avoid that and return a JSON response instead. All of that said - there seems to be little reason to implementi this, since assertions are "truly serious" errors. - `FOSSIL-1107`: Allocation/out of memory error. This cannot be reasonably reported because fossil aborts if an allocation fails. - `FOSSIL-1108`: Requested API is not yet implemented. - `FOSSIL-1109`: Panic! Fossil's `fossil_panic()` or `cgi_panic()` was called. In non-JSON HTML mode this produces an HTTP 500 error. Clients "should" report this as a potential bug, as it "possibly" indicates that the C code has incorrect argument- or error handling somewhere. - `FOSSIL-1110`: Reading of artifact manifest failed. Time to contact your local fossil guru. - `FOSSIL-1111`: Opening of file failed (e.g. POST data provided to CLI mode). **`FOSSIL-2000`: Authentication/Access Error Category** - `FOSSIL-2001`: Privileged request was missing authentication token/cookie. - `FOSSIL-2002`: Access to requested resource was denied. Oftentimes the `resultText` property will contain a human-language description of the access rights needed for the given command. - `FOSSIL-2003`: Requested command is not available in the current operating mode. Returned in CLI mode by commands which require HTTP mode (e.g. login), and vice versa. FIXME: now that we can simulate POST in CLI mode, we can get rid of this distinction for some of the commands. - `FOSSIL-2100`: Login Failed. - `FOSSIL-2101`: Anonymous login attempt is missing the "anonymousSeed" property (fetched via [the `/json/anonymousPassword` request](api-auth.md#login-anonymous)). Note that this is more specific form of `FOSSIL-3002`. ONLY FOR TESTING purposes should the remaning 210X sub-codes be enabled (they are potentially security-relevant, in that the client knows which part of the request was valid/invalid): - `FOSSIL-2102`: Name not supplied in login request - `FOSSIL-2103`: Password not supplied in login request - `FOSSIL-2104`: No name/password match found **`FOSSIL-3000`: Usage Error Category** - `FOSSIL-3001`: Invalid argument/parameter type(s) or value(s) in request - `FOSSIL-3002`: Required argument(s)/parameter(s) missing from request - `FOSSIL-3003`: Requested resource identifier is ambiguous (e.g. a shortened hash that matches multiple artifacts, an abbreviated date that matches multiple commits, etc.) - `FOSSIL-3004`: Unresolved resource identifier. A branch/tag/uuid provided by client code could not be resolved. This is a special case of #3006. - `FOSSIL-3005`: Resource already exists and overwriting/replacing is not allowed. e.g. trying to create a wiki page or user which already exists. FIXME? Consolidate this and resource-not-found into a separate category for dumb-down purposes? - `FOSSIL-3006`: Requested resource not found. e.g artifact ID, branch name, etc. **`FOSSIL-4000`: Database-related Error Category** - `FOSSIL-4001`: Statement preparation failed. - `FOSSIL-4002`: Parameter binding failed. - `FOSSIL-4003`: Statement execution failed. - `FOSSIL-4004`: Database locked (this is not used anywhere, but reserved for future use). Special-case DB-related errors... - `FOSSIL-4101`: Fossil Schema out of date (repo rebuild required). - `FOSSIL-4102`: Fossil repo db could not be found. - `FOSSIL-4103`: Repository db is not valid (possibly corrupt). - `FOSSIL-4104`: Check-out not found. This is similar to FOSSIL-4102 but indicates that a local checkout is required (but was not found). Note that the 4102 gets triggered earlier than this one, and so can appear in cases when a user might otherwise expect a 4104 error. Some of those error codes are of course "too detailed" for the client to do anything with (e.g.. 4001-4004), but their intention is to make it easier for Fossil developers to (A) track down problems and (B) support clients who report problems. If a client reports, "I get a FOSSIL-4000, how can I fix it?" then the developers/support personnel can't say much unless they know if it's a 4001, 4002, 4003, 4004, or 4101 (in which case they can probably zero in on the problem fairly quickly, since they know which API call triggered it and they know (from the error code) the general source of the problem). ## Why Standard/Immutable Result Codes are Important - They are easily internationalized (i.e. associated with non-English error text) - Clients may be able to add automatic retry strategies for certain problem types by examining the result code. e.g. if fossil returns a locking or timeout error \[it currently does no special timeout/locking handling, by the way\] the client could re-try, whereas a usage error cannot be sensibly retried with the same inputs. - The "category" structure described above allows us some degree of flexibility in how detailed the reported errors are reported. - While the string prefix "FOSSIL-" on the error codes may seem superfluous, it has one minor *potential* advantage on the client side: when managing several unrelated data sources, these error codes can be immediately identified (by higher-level code which may be ignorant of the data source) as having come from the fossil API. Think "ORA-111" vs. "111". |

It will only improve via feedback from those working on the code. --- <a id="before-committing"></a> # Before Committing Changes... Because this code lives in the trunk, there are certain guidelines which must be followed before committing any changes: 1. Read the [checkin preparation list](/doc/trunk/www/checkin.wiki). 2. Changes to the files `src/json_*.*`, and its related support code (e.g. `ajax/*.*`), may be made freely without affecting mainline users. Changes to other files, unless they are trivial or made for purposes outside the JSON API (e.g. an unrelated bug fix), must be reviewed carefully before committing. When in doubt, create a branch and post a request for a review. 3. The Golden Rule is: *do not break the trunk build*. <a id="json-c-api"></a> # JSON C API libcson, the underlying JSON API, is a separate project, included in fossil in "amalgamation" form: see `src/cson_amalgamation.[ch]`. It has thorough API docs and a good deal of information is in its wiki: [](https://fossil.wanderinghorse.net/wikis/cson/) In particular: [](https://fossil.wanderinghorse.net/wikis/cson/?page=CsonArchitecture) gives an overview of its architecture. Occasionally new versions of it are pulled into the Fossil tree, but other developers generally need not concern themselves with that. (Trivia: the cson wiki's back-end is fossil, living on top of a JavaScript+HTML5 application.) Only a small handful of low-level fossil routines actually input or output JSON text (only for reading in POST data and sending the response). In the C code we work with the higher-level JSON value abstractions provided by cson (conceptually similar to an XML DOM). All of the JSON-defined data types are supported, and we can construct JSON output of near arbitrary complexity with the caveat that *cyclic data structures are strictly forbidden*, and *will* cause memory corruption, crashes, double free()'s, or other undefined behaviour. Because JSON cannot, without client-specific semantic extensions to JSON, represent cyclic structures, it is not anticipated that this will be a problem/limitation when generating output for fossil. <a id="json-commands"></a> # Architecture of JSON Commands In order to consolidate CLI/HTTP modes for JSON handling, this code foregoes fossil's conventional command/path dispatching mechanism. Only the top-most "json" command/path is dispatched directly by fossil's core. The disadvantages of this are that we lose fossil's conventional help text mechanism (which is based on code comments in the command/path's dispatcher impl) and the ability to write abbreviated command names in CLI mode ("json" itself may be abbreviated, but not the subcommands). The advantages are that we can handle CLI/HTTP modes almost identically (there are a couple minor differences) by unifying them under the same callback functions much more easily. The top-level "json" command/path uses its own dispatching mechanism which uses either the path (in HTTP mode) or CLI positional arguments to dispatch commands (stopping at the first "flag option" (e.g. -foo) in CLI mode). The command handlers are simply callback functions which return a cson\_value pointer (the C representation of an arbitrary JSON value), representing the "payload" of the response (or NULL - not all responses need a payload). On error these callbacks set the internal JSON error state (detailed in a subsection below) and return NULL. The top-level dispatcher then creates a response envelope and returns the "payload" from the command (if any) to the caller. If a callback sets the error state, the top-level dispatcher takes care to set the error information in the response envelope. In summary: - The top-level dispatchers (`json_page_top()` and `json_cmd_top()`) are called by fossil's core when the "json" command/path is called. They initialize the JSON-mode global state, dispatch the requested command, and handle the creation of the response envelope. They prepare all the basic things which the individual subcommands need in order to function. - The command handlers (most are named `json_page_something()`) implement the `fossil_json_f()` callback interface (see [`src/json_detail.h`](/finfo/src/json_detail.h)). They are responsible for permissions checking, setting any error state, and passing back a payload (if needed - not all commands return a payload). It is strictly forbidden for these callbacks to produce any output on stdout/stderr, and doing so effectively corrupts the out-bound JSON and HTTP headers. There is a wrench in all of that, however: the vast majority of fossil's commands "fail fast" - they will `exit()` if they encounter an error. To handle that, the fossil core error reporting routines have been refactored a small bit to operate differently when we are running in JSON mode. Instead of the conventional output, they generate a JSON error response. In HTTP mode they exit with code 0 to avoid causing an HTTP 500 error, whereas in CLI mode they will exit with a non-0 code. Those routines still `exit()`, as in the conventional CLI/HTTP modes, but they will exit differently. Because of this, it is perfectly fine for a command handler to exit via one of fossil's conventional mechanisms (e.g. `db_prepare()` can be fatal, and callbacks may call `fossil_panic()` if they really want to). One exception is `fossil_exit()`, which does _not_ generate any extra output and will `exit()` the app. In the JSON API, as a rule of thumb, `fossil_exit()` is only used when we *want* a failed request to cause an HTTP 500 error, and it is reserved for allocation errors and similar truly catostrophic failures. That said... libcson has been hacked to use `fossil_alloc()` and friends for memory management, and those routines exit on error, so alloc error handling in the JSON command handler code can afford to be a little lax (the majority of *potential* errors clients get from the cson API have allocation failure as their root cause). As a side-note: the vast majority (if not all) of the cson API calls are "NULL-safe", meaning that will return an error code (or be a no-op) if passed NULL arguments. e.g. the following chain of calls will not crash if the value we're looking for does not exist, is-not-a String (see `cson_value_get_string()` for important details), or if `myObj` is NULL: ```c const char * str = cson_string_cstr( // get the C-string form of a cson_string cson_value_get_string( // get its cson_string form cson_object_get(myObj,"foo") // search for key in an Object ) ); ``` If `"foo"` is not found in `myObj` (or if `myObj` is NULL) then v will be NULL, as opposed to stepping on a NULL pointer somewhere in that call chain. Note that all cson JSON values except Arrays and Objects are *immutable* - you cannot change a string's or number's value, for example. They also use reference counting to manage ownership, as documented and demonstrated on this page: [](https://fossil.wanderinghorse.net/wikis/cson/?page=TipsAndTricks) In short, after creating a new value you must eventually *either* add it to a container (Object or Array) to transfer ownership *or* call `cson_value_free()` to clean it up (exception: the Fossil/JSON command callbacks *return* a value to transfer ownership to the dispatcher). Sometimes it's more complex than that, but not normally. Any given value may legally be stored in any number of containers (or multiple times within one container), as long as *no cycles* are introduced (cycles *will* cause undefined behaviour). Ownership is shared using reference counting and the value will eventually be freed up when its last remaining reference is freed (e.g. when the last container holding it is cleaned up). For many examples of using cson in the context of fossil, see the existing `json_page_xxx()` functions in `json_*.c`. <a id="reporting-errors"></a> # Reporting Errors To report an error from a command callback, one abstractly needs to: - Set g.json.resultCode to one of the `FSL_JSON_E_xxx` values (defined in [`src/json_detail.h`](/finfo/src/json_detail.h)). - *Optionally* set `g.zErrMsg` to contain the (dynamically-allocated!) error string to be sent to the client. If no error string is set then a standard/generic string is used for the given error code. - Clean up any resources created so far by the handler. - Return NULL. If it returns non-NULL, the dispatcher will destroy the value and not include it in the error response. That normally looks something like this: ``` if(!g.perm.Read){ json_set_err(FSL_JSON_E_DENIED, "Requires 'o' permissions."); return NULL; } ``` `json_set_err()` is a variadic printf-like function, and can use the printf extensions supported by mprintf() and friends (e.g. `%Q` and `%q`) (but they are normally not needed in the context of JSON). If the error string is NULL or empty then `json_err_cstr(errorCode)` is used to fetch the standard/generic error string for the given code. When control returns to the top-level dispatching function it will check `g.json.resultCode` and, if it is not 0, create an error response using the `g.json.resultCode` and `g.zErrMsg` to construct the response's `resultCode` and `resultText` properties. If a function wants to output an error and exit by itself, as opposed to returning to the dispatcher, then it must behave slightly differently. See the docs for `json_err()` (in [`src/json.c`](/finfo/src/json.c)) for details, and search that file for various examples of its usage. It is also used by fossil's core error-reporting APIs, e.g. `fossil_panic()` (defined in [`src/main.c`](/finfo/src/main.c)). That said, it would be "highly unusual" for a callback to need to do this - it is *far* simpler (and more consistent/reliable) to set the error state and return to the dispatcher. <a id="command-args"></a> # Getting Command Arguments Positional parameters can be fetched usinig `json_command_arg(N)`, where N is the argument position, with position 0 being the "json" command/path. In CLI mode positional arguments have their obvious meaning. In HTTP mode the request path (or the "command" request property) is used to build up the "command path" instead. For example: CLI: `fossil json a b c` HTTP: `/json/a/b/c` HTTP POST or CLI with `--json-input`: /json with POSTed envelope `{"command": "a/b/c" …}` Those will have identical "command paths," and `json_command_path(2)` would return the "b" part. Caveat: a limitation of this support is that all CLI flags must come *after* all *non-flag* positional arguments (e.g. file names or subcommand names). Any argument starting with a dash ("-") is considered by this code to be a potential "flag" argument, and all arguments after it are ignored (because the generic handling cannot know if a flag requires an argument, which changes how the rest of the arguments need to be interpreted). To get named parameters, there are several approaches (plus some special cases). Named parameters can normally come from any of the following sources: - CLI arguments, e.g. `--foo bar` - GET parameters: `/json/...?foo=bar` - Properties of the POST envelope - Properties of the `POST.payload` object (if any). To try to simplify the guessing process the API has a number of functions which behave ever so slightly differently. A summary: - `json_getenv()` and `json_getenv_TYPE()` search the so-called "JSON environment," which is a superset of the GET/POST/`POST.payload` (if `POST.payload` is-a Object). - `json_find_option_TYPE()`: searches the CLI args (only when in CLI mode) and the JSON environment. - The use of fossil's `P()` and `PD()` macros is discourages in JSON callbacks because they can only handle String data from the CLI or GET parameters (not POST/`POST.payload`). (Note that `P()` and `PD()` *normally* also handle POSTed keys, but they only "see" values posted as form-urlencoded fields, and not JSON format.) - `find_option()` (from `src/main.c`) "should" also be avoided in JSON API handlers because it removes flag from the g.argv arguments list. That said, the JSON API does use `find_option()` in several of its option-finding convenience wrappers. For example code: the existing command callbacks demonstrate all kinds of uses and the various styles of parameter/option inspection. Check out any of the functions named `json_page_SOMETHING()`. <a href="creating-json"></a> # Creating JSON Data <a href="creating-json-values"></a> ## Creating JSON Values cson has a fairly rich API for creating and manipulating the various JSON-defined value types. For a detailed overview and demonstration i recommend reading: [](https://fossil.wanderinghorse.net/wikis/cson/?page=HowTo) That said, the Fossil/JSON API has several convenience wrappers to save a few bytes of typing: - `json_new_string("foo")` is easier to use than `cson_value_new_string("foo", 3)`, and `json_new_string_f("%s","foo")` is more flexible. - `json_new_int()` is easier to type than `cson_value_new_integer()`. - `cson_output_Blob()` and `cson_parse_Blob()` can write/read JSON to/from fossil `Blob`-type objects. It also provides several lower-level JSON features which aren't of general utility but provide necessary functionality for some of the framework-level code (e.g. `cson_data_dest_cgi()`), which is only used by the deepest of the JSON internals). <a href="query-to-json"></a> ## Converting SQL Query Results to JSON The `cson_sqlite3_xxx()` family of functions convert `sqlite3_stmt` rows to Arrays or Objects, or convert single columns to a JSON-compatible form. See `json_stmt_to_array_of_obj()`, `json_stmt_to_array_of_array()` (both in `src/json.c`), and `cson_sqlite3_column_to_value()` and friends (in `src/cson_amalgamation.h`). They work in an intuitive way for numeric types, but they optimistically/natively *assume* that any fields of type TEXT or BLOB are actually UTF8 data, and treat them as such. cson's string class only handles UTF8 data and it is semantically illegal to feed them anything but UTF8. Violating this will likely result in down-stream errors (e.g. when emiting the JSON string output). **The moral of this story is:** *do not use these APIs to fetch binary data*. JSON doesn't do binary and the `cson_string` class does not protect itself against clients feeding it non-UTF8 data. Here's a basic example of using these features: ```c Stmt q = empty_Stmt; cson_value * rows = NULL; db_prepare(&q, "SELECT a AS a, b AS b, c AS c FROM foo"); rows = json_stmt_to_array_of_obj( &sql, NULL ); db_finalize(&q); // side note: if db_prepare()/finalize() fail (==they exit()) // then a JSON-format error reponse will be generated. ``` On success (and if there were results), `rows` is now an Array value, each entry of which contains an Object containing the fields (key/value pairs) of each row. `json_stmt_to_array_of_array()` returns each row as an Array containing the column values (with no column name information). **Note the seemingly superfluous use of the "AS" clause in the above SQL.** Having them is actually significant! If a query does *not* use AS clauses, the row names returned by the db driver *might* be different than they appear in the query (this is documented behaviour of sqlite3). Because the JSON API needs to return stable field names, we need to use AS clauses to be guaranteed that the db driver will return the column names we want. Note that the AS clause is often used to translate column names into something more JSON-conventional or user-friendly, e.g. "SELECT cap AS capabilities...". Alternately, we can convert the individual `sqlite3_stmt` column values to JSON using `cson_sqlite3_column_to_value()`, without refering directly to the db-reported column name. |

In September, 2011, Fossil contributor Stephan Beal had the great pleasure of meeting D. Richard Hipp, Fossil's author, for lunch in Munich, Germany. During the conversation Richard asked, "what does Fossil need next?" Stephan's first answer was, "refactoring into a library/client, as opposed to a monolithic app." We very quickly agreed that the effort required would be "herculean," and second choice was voiced, "a JSON API." They briefly discussed the idea and Richard gave his blessing. That night work began. Why a JSON API? Because it is the next best thing to the "librification" of Fossil, in that it makes Fossil's features available to near-arbitrary applications using a simple, globally available data format. <a id="building"></a> # Building JSON Support In environments supported by fossil's `configure` script, simply pass `--enable-json` to it: ``` $ ./configure --prefix=$HOME --enable-json ... ``` When built without that option, JSON support is disabled. **When reconfiguring the source tree**, ***always be sure to do a "make clean"*** (or equivalent for your platform) between builds (preferably *before* reconfiguring), to ensure that everything is rebuilt properly. If you fail to do that after enabling JSON on a tree which has already been built, most of the sources will not be rebuilt properly. The reason is that the JSON files are actually unconditionally compiled, but when built without `--enable-json` they compile to empty object files. Thus after a reconfigure the (empty) object files are still up-to-date vis-a-vis the sources, and won't be rebuilt. To build Fossil with JSON support on Windows using the Microsoft C compiler: ``` cd win nmake -f Makefile.msc FOSSIL_ENABLE_JSON=1 ``` It has been seen to compile in VC versions 6 and higher. <a id="goals"></a> # Goals & Non-goals The API described here is most certainly not [*REST*](http://en.wikipedia.org/wiki/Representational_state_transfer)-conformant, but is instead JSON over HTTP. The error reporting techniques of the REST conventions (using HTTP error codes) "does not mesh" with my ideas of separation of transport- vs. app-side errors. Additionally, REST requires HTTP methods which are not specified by CGI (namely PUT and DELETE), which means we can't possibly implement a REST-compatible interface on top of fossil (which uses CGI mode even for its built-in server). The **overall goals** of this effort include: - A JSON-based API off of which clients can build customized Fossil UIs and special-purpose applications. e.g. a desktop notification applet which polls for new timeline data. - Arbitrary JSON-using clients should be able to use it. Though JSON originates from JavaScript, it is truly a cross-platform data format with a very high adoption rate. (There’s even a JSON implementation for Oracle PL/SQL.) - Fossil’s CGI and Server modes are the main targets and should be supported equally. CLI JSON mode is of secondary concern (but is in practice easier to test, so it’s generally implemented first). The ***non-goals*** include: - We won’t be able to implement *every* feature of Fossil via a JSON interface, and we won’t try to. - Binary data (e.g. commits of binary files or downloading ZIP files) is not an initial goal, but "might be interesting" once the overall infrastructure is in place and working well. See below for more details about binary data in JSON. - A "pure REST" interface is seemingly not possible due to REST relying on HTTP methods not specified in the CGI standard (PUT and DELETE). Additionally, REST-style error reporting cannot be used by non-HTTP clients (which this code supports). Adding JSON support also gives us a framework off of which to build/enhance other features. Some examples include: - **Internationalization**. Errors are reported via standard codes and the raw artifact data is language-independent. - The ability to author **special-case clients**, e.g. a ticket poller. - Use **arbitrary HTTP-capable languages** to implement such tools. Programming languages which can execute programs and intercept their stdout output can use the JSON API via a local fossil binary. - **Automatable tests.** Many of fossil's test results currently have to be "visually reviewed" for correctness after changes (e.g. changes in the HTML interface). JSON structures can be programmatically checked for correctness. Artifacts are immutable, which allows us to be very specific in what data to expect as output (for artifact-specific requests the payload data will often (but not always) be the same across all requests and all time). <a id="potential-uses"></a> # Potential Client-side Uses Some of the potential client-side uses of this API include... - Custom apps/applets to fetch timeline/ticket/etc. information from arbitrary repositories. There are many possibilities here, including "dashboard" sites which monitor several repositories. - Custom post-commit triggers, by polling for changes and reacting to them (e.g. sending mails). - A custom wiki front-end which uses fossil as the back-end storage, inheriting its versioning and user access support while providing a completely custom wiki-centric UI. Such a wiki need not have, on the surface, anything to do with fossil or source control, as fossil would just become a glorified wiki back-end. This approach also allows clients to serve wiki pages in a format of their choice - since all rendering would be done client-side, they could use whatever format they like. <a id="considerations"></a> # Technical Problems and Considerations A random list of considerations which need to be made and potential problem areas... - **Binary data:** HTML4 and JavaScript have no portable way of handling binary data, so commands which could potentially deal with binary data (e.g. committing a file) are ruled out for the time being. HTML5 and accompanying JavaScript additions will binary data usable client-side. That said, a JSON interface cannot natively work with binary unless it is encoded (base64 or hex or whatever), and such encoding would have to be understood on both the server and client sides, which may rule out usage in some environments.\ **Status:** deferred until needed. My current thinking is to send URLs instead of binary data, and the URLs would point to some path which produces the raw artifact content. We could read POSTed binary input, but this might require some re-tooling of fossil's innards and it precludes the use of a JSON request envelope, so it would be limited to requests which can be configured solely via GET arguments (as opposed to POST envelope/payload options). i.e. configure the JSON bits via GET and POST the binary data. - **64-bit integers:** JSON does not specify integer precision, probably because it targets many different platforms and not all of them can support more than 32 bits. JavaScript (from which JSON derives) supports 53 bits of integer precision. That said, it's "highly unlikely" that we'll have any range problems with "only" 53 bits of precision. The underlying JSON API supports *signed* 32- or 64-bit integers on both 32- and 64-bit builds, but only if "long long" or `int64_t` are available (from the C99 header `stdint.h`). Only multi-gig repositories are ever expected to use large numbers, and even then only rarely (e.g. via the "stat" command). - **Timestamps:** for portability this API uses GMT Unix Epoch timestamps. They are the most portable time representation out there, easily usable in most programming environments. (In hindsight, this should have been Unix + Milliseconds, but the API already pervasively uses seconds-precision.) - **Artifact vs. Artefact:** both are correct vis-a-vis the english language but Fossil consistently uses the former, so we’ll use that. - **Multiple logins per user:** fossil currently does not allow multiple active logins for a given user except anonymous. For all others, the most recent login wins. This is only a very minor annoyance for the HTML interface but will be more problematic for JSON clients. e.g. a user might have a ticket poller and a commit poller running, and both would need to be logged in.\ **Status:** as of 20120315 (commit [*73038baaa3*](http://www.fossil-scm.org/index.html/info/73038baaa3)), fossil allows a user to be logged in multiple times (confirm: only within the same network?). The only caveat is that if any one of them logs out, it will invalidate the login session for the others. This is good enough for the time being, however. It will likely only become painful if we actually get enough apps in the wild that someone might have some running on his mobile phone and some on his PC and some on his server. The workarounds for now are (A) not to log out and (B) program apps/applets/widgets to try to re-login occasionally. Fossil will at some point expire the login, anyway. FIXME: update the expiry time on each request? To do that right we'd have to re-set the cookie on each request :/. We could optionally add a new JSON request which simply updates the login cookie lifetime (e.g. /json/keepalive or expand /json/whoami to do that). |

When posting data to fossil, make sure that the request sends: - **Content-Type** of `application/json`. Fossil also (currently) accepts `application/javascript` and `text/plain` as JSON input, but `application/json` is preferred. The client may optionally send `;charset=utf-8` with the Content-Type, but any other encoding produces undefined results. Behaviour without the charset or with `;charset=utf-8` suffix is identical. - **POST data must be an non-form-encoded JSON string** (ASCII or UTF-8). jQuery, by default, form-urlencodes it, which the fossil json bits cannot read. e.g. post the result of `JSON.stringify(requestObject)`, without any additional encoding on top of it. - **When POSTing via jQuery**, set these AJAX options: - `contentType:'application/json'` - `dataType:'text'` - `data:JSON.stringify(requestObject)` - **When POSTing via XMLHttpRequest** (XHR), be sure to: - `xhr.open( … )` - `xhr.setRequestHeader("Content-Type", "application/json")` - `xhr.send( JSON.stringify( requestObject ) )` The response will be (except in the case of an HTTP 500 error or similar) a JSON or JSONP string, ready to be parsed by your favourite `JSON.parse()` implementation or `eval()`'d directly. <a id="curl-wget"></a> ## Using `curl` and `wget` Both [curl](https://curl.haxx.se/) and [wget](https://www.gnu.org/software/wget/) can be used to post data to this API from the command line or scripts, but both require an extra parameter to set the request encoding. Example: ```console $ cat x.json { "payload": { "sql": "SELECT * FROM reportfmt limit 1", "format": "o" } } # Fossil has been started locally with: # fossil server --localauth # which allows the following requests to work without extra # authenticaion: $ wget -q -O- \ --post-file=x.json \ --header="Content-Type: application/json" \ 'http://localhost:8080/json/query' $ curl \ --data-binary @x.json \ --header 'Content-Type: application/json' \ 'http://localhost:8080/json/query' ``` The relevant parts for encoding are the `--header` flag for `wget` and `curl`, noting that they have different syntaxes for each (`--header=X` vs `--header X`). <a id="javascript"></a> # Example JavaScript (Browser and Shell) In the fossil source tree, [in the ajax directory](/dir/ajax), is test/demo code implemented in HTML+JavaScript. While it is still quite experimental, it demonstrates one approach to creating client-side wrapper APIs for remote Fossil/JSON repositories. There is some additional JS test code, which uses the Rhino JS engine (i.e. from the console, not the browser), under [`ajax/i-test`](/dir/ajax/-itest). That adds a Rhino-based connection back-end to the AJAJ API and uses it for running integration-style tests against an arbitrary JSON-capable repository. <a id="demo-apps"></a> # Demo Apps Known in-the-wild apps using this API: - The wiki browsers/editors at [](https://fossil.wanderinghorse.net/wikis/) |

The Fossil [self-hosting server][sh] is a 1/24th slice VM at [Linode.com][lin] hosting 65 other repositories in addition to Fossil, including some very high-traffic sites such as <http://www.sqlite.org> and <http://system.data.sqlite.org>. This small VM has a typical load of 0.05 to 0.1. A single HTTP request to Fossil normally takes less than 10 milliseconds of CPU time to complete, so requests can be arriving at a continuous rate of 20 or more per second, and the CPU can still be mostly idle. However, there are some Fossil web pages that can consume large amounts of CPU time, especially on repositories with a large number of files or with long revision histories. High CPU usage pages include [`/zip`](/help/zip), [`/tarball`](/help/tarball), [`/annotate`](/help/annotate), and others. On very large repositories, these commands can take 15 seconds or more of CPU time. If these kinds of requests arrive too quickly, the load average on the server can grow dramatically, making the server unresponsive. Fossil provides two capabilities to help avoid server overload problems due to excessive requests to expensive pages: 1. An optional cache is available that remembers the 10 most recently requested `/zip` or `/tarball` pages and returns the precomputed answer if the same page is requested again. 2. Page requests can be configured to fail with a “[503 Server Overload][503]†HTTP error if an expensive request is received while the host load average is too high. Both of these load-control mechanisms are turned off by default, but they are recommended for high-traffic sites. The webpage cache is activated using the [`fossil cache init`](/help/cache) command-line on the server. Add a `-R` option to specify the specific repository for which to enable caching. If running this command as root, be sure to “`chown`†the cache database to give the Fossil server write permission for the user ID of the web server; this is a separate file in the same directory and with the same name as the repository but with the “`.fossil`†suffix changed to “`.cache`â€. To activate the server load control feature visit the Admin → Access setup page in the administrative web interface; in the “**Server Load Average Limit**†box enter the load average threshold above which “503 Server Overload†replies will be issued for expensive requests. On the self-hosting Fossil server, that value is set to 1.5, but you could easily set it higher on a multi-core server. The maximum load average can also be set on the command line using commands like this: fossil set max-loadavg 1.5 fossil all set max-loadavg 1.5 The second form is especially useful for changing the maximum load average simultaneously on a large number of repositories. Note that this load-average limiting feature is only available on operating systems that support the [`getloadavg()`][gla] API. Most modern Unix systems have this interface, but Windows does not, so the feature will not work on Windows. Because Linux implements `getloadavg()` by accessing the `/proc/loadavg` virtual file, you will need to make sure `/proc` is available to the Fossil server. The most common reason for it to not be available is that you are running a Fossil instance [inside a `chroot(2)` jail](./chroot.md) and you have not mounted the `/proc` virtual file system inside that jail. On the [self-hosting Fossil repositories][sh], this was accomplished by adding a line to the `/etc/fstab` file: chroot_jail_proc /home/www/proc proc ro 0 0 The `/home/www/proc` pathname should be adjusted so that the `/proc` component is at the root of the chroot jail, of course. To see if the load-average limiter is functional, visit the [`/test_env`][hte] page of the server to view the current load average. If the value for the load average is greater than zero, that means that it is possible to activate the load-average limiter on that repository. If the load average shows exactly "0.0", then that means that Fossil is unable to find the load average. This can either be because it is in a `chroot(2)` jail without `/proc` access, or because it is running on a system that does not support `getloadavg()` and so the load-average limiter will not function.

Most users will download a [https://www.fossil-scm.org/fossil/uv/download.html | precompiled binary] so this is of no consequence to them, and even those who want to compile the code themselves can use one of the [./build.wiki | existing makefiles]. So must people do not need to be concerned with the build complexities of Fossil. But hard-core developers who desire a deep understanding of how Fossil is put together can benefit from reviewing this article. <a name="srctour"></a> <h1>2.0 Source Code Tour</h1> The source code for Fossil is found in the [/dir?ci=trunk&name=src | src/] subdirectory of the source tree. The src/ subdirectory contains all code, including the code for the separate preprocessor programs. Each preprocessor program is a separate C program implemented in a single file of C source code. The three preprocessor programs are: 1. [/file/src/mkindex.c | mkindex.c] 2. [/file/src/translate.c | translate.c] 3. [/file/src/makeheaders.c | makeheaders.c] Fossil uses [http://www.sqlite.org/ | SQLite] for on-disk storage. The SQLite implementation is contained in three source code files that do not participate in the preprocessing steps. These three files that implement SQLite are: 4. sqlite3.c 5. sqlite3.h 6. shell.c All three SQLite source files are byte-for-byte copies of files by the same name in the standard [http://www.sqlite.org/amalgamation.html | amalgamation]. The sqlite3.c file implements the database engine. The shell.c file implements the command-line shell, which is accessed in fossil using the [/help?cmd=sqlite3 | fossil sql] command. The shell.c command-line shell uses the [https://github.com/antirez/linenoise | linenoise] library to implement line editing. linenoise comprises two source files which were copied from the upstream repository with only very minor portability edits: 7. linenoise.c 8. linenoise.h The TH1 script engine is implemented using files: 9. th.c 10. th.h The proprocessing steps are omitted for all of these imported files. The VERSION.h header file is generated from other information sources using a small program called: 11. [/file/src/mkversion.c | mkversion.c] The builtin_data.h header file contains the definitions of C-language byte-array constants that contain various resources such as scripts and images. The builtin_data.h header file is generate from the original resource files using a small program called: 12 [/file/src/mkbuiltin.c | mkbuiltin.c] Examples of built-in resources include the [/file/src/diff.tcl | diff.tcl] script used to implement the --tk option to [/help?cmd=diff| fossil diff], the [/file/src/markdown.md | markdown documentation], and the various CSS scripts, headers, and footers used to implement built-in skins. New resources files are added to the "extra_files" variable in [/file/src/makemake.tcl | makemake.tcl]. The src/ subdirectory also contains documentation about the makeheaders preprocessor program: 13. [../src/makeheaders.html | makeheaders.html] Click on the link to read this documentation. In addition there is a [http://www.tcl-lang.org/ | Tcl] script used to build the various makefiles: 14. makemake.tcl Running this Tcl script will automatically regenerate all makefiles. In order to add a new source file to the Fossil implementation, simply edit makemake.tcl to add the new filename, then rerun the script, and all of the makefiles for all targets will be rebuild. There is an option code verification step implemented using 15. [/file/src/codecheck1.c | codecheck1.c] This file implements a small utility program ("codecheck1") that scans other Fossil source files looking for errors in printf-style format strings. The codecheck1 utility detects missing or surplus arguments on printf-like functions and dangerous uses of "%s" that might permit SQL injection or cross-site scripting attacks. This code check step is run automatically on each build of Fossil, and can also be run separately by typing "make codecheck". Note that the built-in printf format checking of GCC does not function for Fossil since Fossil implements its own printf (in the [/file/src/printf.c | printf.c] source file) that includes special features and formatting letters that are useful to Fossil. The codecheck1 utility can be seen as an enhanced application-specific replacement for the GCC printf format checker. Finally, there is one of the makefiles generated by makemake.tcl: 16. main.mk The main.mk makefile is invoked from the Makefile in the top-level directory. The main.mk is generated by makemake.tcl and should not be hand edited. Other makefiles generated by makemake.tcl are in other subdirectories (currently all in the win/ subdirectory). All the other files in the src/ subdirectory (79 files at the time of this writing) are C source code files that are subject to the preprocessing steps described below. In the sequel, we will call these other files "src.c" in order to have a convenient name. The reader should understand that whenever "src.c" or "src.h" is used in the text that follows, we really mean all (79) other source files other than the exceptions described above. <h1>3.0 Automatically generated files</h1> The "VERSION.h" header file contains some C preprocessor macros that identify the version of Fossil that is to be build. The VERSION.h file is generated automatically from information extracted from the "manifest", "manifest.uuid", and "VERSION" source files in the root directory of the source tree. (The "manifest" and "manifest.uuid" files are automatically generated and updated by Fossil itself. See the [/help/setting | fossil set manifest] command for additional information.) The VERSION.h header file is generated by a C program: src/mkversion.c. To run the VERSION.h generator, first compile the src/mkversion.c source file into a command-line program (named "mkversion.exe") then run: <blockquote><pre> mkversion.exe manifest.uuid manifest VERSION >VERSION.h </pre></blockquote> The pathnames in the above command might need to be adjusted to get the directories right. The point is that the manifest.uuid, manifest, and VERSION files in the root of the source tree are the three arguments and the generated VERSION.h file appears on standard output. The builtin_data.h header file is generated by a C program: src/mkbuiltin.c. The builtin_data.h file contains C-langauge byte-array definitions for the content of resource files used by Fossil. To generate the builtin_data.h file, first compile the mkbuiltin.c program, then run: <blockquote><pre> mkbuiltin.exe diff.tcl <i>OtherFiles...</i> >builtin_data.h </pre></blockquote> At the time of this writing, the "diff.tcl" script (a Tcl/Tk script used to generate implement --tk option on the diff command) is the only resource file processed using mkbuiltin.exe. However, new resources will likely be added using this facility in future versions of Fossil. <a name="preprocessing"></a> <h1>4.0 Preprocessing</h1> There are three preprocessors for the Fossil sources. The mkindex and translate preprocessors can be run in any order. The makeheaders preprocessor must be run after translate. <h2>4.1 The mkindex preprocessor</h2> The mkindex program scans the "src.c" source files looking for special comments that identify routines that implement various Fossil commands, web interface methods, and help text comments. The mkindex program generates some C code that Fossil uses in order to dispatch commands and HTTP requests and to show on-line help. Compile the mkindex program from the mkindex.c source file. Then run: <blockquote><pre> ./mkindex src.c >page_index.h </pre></blockquote> Note that "src.c" in the above is a stand-in for the (79) regular source files of Fossil - all source files except for the exceptions described in section 2.0 above. The output of the mkindex program is a header file that is #include-ed by the main.c source file during the final compilation step. <h2>4.2 The translate preprocessor</h2> The translate preprocessor looks for lines of source code that begin with "@" and converts those lines into string constants or (depending on context) into special "printf" operations for generating the output of an HTTP request. The translate preprocessor is a simple C program whose sources are in the translate.c source file. The translate preprocess is run on each of the other ordinary source files separately, like this: <blockquote><pre> ./translate src.c >src_.c </pre></blockquote> In this case, the "src.c" file represents any single source file from the set of ordinary source files as described in section 2.0 above. Note that each source file is translated separately. By convention, the names of the translated source files are the names of the input sources with a single "_" character at the end. But a new makefile can use any naming convention it wants - the "_" is not critical to the build process. After being translated, the output files (the "src_.c" files) should be used for all subsequent preprocessing and compilation steps. <h2>4.3 The makeheaders preprocessor</h2> |

This can be done all at once, or each preprocessed source file can be compiled into a separate object code file and the resulting object code files linked together in a final step. Some files require special C-preprocessor macro definitions. When compiling sqlite.c, the following macros are recommended: * -DSQLITE_OMIT_LOAD_EXTENSION=1 * -DSQLITE_ENABLE_DBSTAT_VTAB=1 * -DSQLITE_ENABLE_FTS4=1 * -DSQLITE_ENABLE_LOCKING_STYLE=0 * -DSQLITE_LIKE_DOESNT_MATCH_BLOBS=1 * -DSQLITE_THREADSAFE=0 * -DSQLITE_DEFAULT_FILE_FORMAT=4 * -DSQLITE_ENABLE_EXPLAIN_COMMENTS=1 The first three symbol definitions above are required; the others are merely recommended. Extension loading is omitted as a security measure. The dbstat virtual table is needed for the [/help?cmd=/repo-tabsize|/repo-tabsize] page. FTS4 is needed for the search feature. Fossil is single-threaded so mutexing is disabled in SQLite as a performance enhancement. The SQLITE_ENABLE_EXPLAIN_COMMENTS option makes the output of "EXPLAIN" queries in the "[/help?cmd=sqlite3|fossil sql]" command much more readable. When compiling the shell.c source file, these macros are required: * -Dmain=sqlite3_main * -DSQLITE_OMIT_LOAD_EXTENSION=1 The "main()" routine in the shell must be changed into sqlite3_main() to prevent it from colliding with the real main() in Fossil, and to give Fossil an entry point to jump to when the [/help/sqlite3 | fossil sql] command is invoked. All the other source code files can be compiled without any special options. <h1>6.0 Linkage</h1> Fossil needs to be linked against [http://www.zlib.net | zlib]. If the HTTPS option is enabled, then it will also need to link against the appropriate SSL implementation. And, of course, Fossil needs to link against the standard C library. No other libraries or external dependences are used. Fossil includes a copy of [https://github.com/richgel999/miniz | miniz] which can be used as an alternative to zlib. <h1>7.0 Debugging</h1> Debug mode is controlled via FOSSIL_DEBUG preprocessor macro which could be set explicitly at the make command for the target platform. However, in practice it is instead recommended to add a respective configure option for the target platform and then perform a clean build. This way the Debug flags are consistently applied across the whole build process. For example, use these Debug flags in addition to other flags passed to the configure scripts: On Linux, *NIX and similar platforms: <blockquote><pre> ./configure --fossil-debug </pre></blockquote> On Windows: <blockquote><pre> win\buildmsvc.bat FOSSIL_DEBUG=1 </pre></blockquote> The resulting fossil binary could then be loaded into a platform-specific debugger. Source files displayed in the debugger correspond to the ones generated from the translation stage of the build process, that is what was actually compiled into the object files. <h1>8.0 See Also</h1> * [./tech_overview.wiki | A Technical Overview Of Fossil] * [./adding_code.wiki | How To Add Features To Fossil] |

Note that the $ROOT translation only occurs within the `<a href="...">` element, not within the text of the hyperlink. So you should see the $ROOT text on this page, but if you mouse-over the hyperlink the $ROOT value should have been expanded to the actual document root. * Timeline: []($ROOT/timeline) * Site-map: []($ROOT/sitemap) The $ROOT prefix on markdown links is superfluous. The same link works without the $ROOT prefix. (Though: the $ROOT prefix is required for HTML documents.) * Timeline: [](/timeline) * Help: [](/help?cmd=help) * Site-map: [](/sitemap) ## The Magic $CURRENT Document Version Translation In URI text of the form `.../doc/$CURRENT/...` the $CURRENT value is converted to the version number of the document currently being displayed. This conversion happens after translation into HTML and only occurs on href='...' attributes so it does not occur for plain text. * Document index: [](/doc/$CURRENT/www/index.wiki) Both the $ROOT and the $CURRENT conversions can occur on the same link. * Document index: []($ROOT/doc/$CURRENT/www/index.wiki) The translations must be contained within HTML markup in order to work. They do not work for ordinary text that appears to be an href= attribute. * `x href='$ROOT/timeline'` * `x action="$ROOT/whatever"` * `x href="https://some-other-site.com/doc/$CURRENT/tail"` |

([Setup instructions](./mirrortogithub.md) and an [example](https://github.com/drhsqlite/fossil-mirror).) But the export to Git is not perfect. Some information is lost during export due to limitations in Git. This page describes what content of Fossil is not included in an export to Git. ## (1) Wiki, Tickets, Technotes, Forum Git only supports version control. The additional features of Fossil such as Wiki, Tickets, Technotes, and the Forum are not supported in Git, so those features are not included in an export. Third-party Git based tooling may add some of these features (e.g. GitHub, GitLab) but because their data are not stored in the Git blockchain, there is no single destination for Fossil to convert its equivalent data *to*. For instance, Fossil tickets do not become GitHub issues, because that is a proprietary feature of GitHub separate from Git proper, stored outside the blockchain on the GitHub servers. You can also see the problem in its inverse case: you do not get a copy of your GitHub issues when cloning the Git repository. You *do* get the Fossil tickets, wiki, forum posts, etc. when cloning a remote Fossil repo. ## (2) Cherrypick Merges The Git client supports cherrypick merges but does not record the cherrypick parent(s). Fossil tracks cherrypick merges in its blockchain and displays cherrypicks in its timeline. (As an example, the dashed lines [here](/timeline?c=0a9f12ce6655b7a5) are cherrypicks.) Because Git does not have a way to represent this same information in its blockchain, the history of Fossil cherrypicks cannot be exported to Git, only their direct effects on the managed file data. ## (3) Named Branches Git has only limited support for named branches. Git identifies the head check-in of each branch. Depending on the check-in graph topology, this is sufficient to infer the branch for many historical check-ins as well. However, complex histories with lots of cross-merging can lead to ambiguities. Fossil keeps track of historical branch names unambiguously, but the extra details about branch names that Fossil keeps at hand cannot be exported to Git. ## (4) Non-unique Tags Git requires tags to be unique: each tag must refer to exactly one check-in. Fossil does not have this restriction, and so it is common in Fossil to tag multiple check-ins with the same name. For example, it is common in Fossil to tag each check-in creating a release both with a unique version tag *and* a common tag like "release" so that all historical releases can be found at once. ([Example](/timeline?t=release).) Git does not allow this. The "release" tag must refer to just one check-in. The work-around is that the non-unique tag in the Git export is made to refer to only the most recent check-in with that tag. This is why the ["release" tag view][ghrtv] in the GitHub mirror of this repository shows only the latest release version; contrast the prior example. Both URLs are asking the repository the same question, but because of Git's relatively impoverished data model, it cannot give the same answer that Fossil does. [ghrtv]: https://github.com/drhsqlite/fossil-mirror/tree/release ## (5) Amendments To Check-ins Check-ins are immutable in both Fossil and Git. However, Fossil has a mechanism by which tags can be added to its blockchain to provide after-the-fact corrections to prior check-ins. For example, tags can be added to check-ins that correct typos in the check-in comment. The original check-in is immutable and so the original comment is preserved in addition to the correction. But software that displays the check-ins knows to look for the comment-change tag and if present displays the corrected comment rather than the original. ([Example](/info/8ed91bbe44d0d383) changing the typo "os" into "so".) Git has no mechanism for providing corrections or clarifications to historical check-ins. When exporting from Fossil to Git, the latest corrections to a Fossil check-in are used to generate the corresponding Git check-in. But once the Git check-in has been created, any subsequent corrections are omitted as there is no way to transfer them to Git. |

Log into that account. <li><p>Create a new project. GitHub will ask you if you want to prepopulate your project with various things like a README file. Answer "no" to everything. You want a completely blank project. GitHub will then supply you with a URL for your project that will look something like this: <blockquote> https://github.com/username/project.git </blockquote> <li><p>Back on your workstation, move to a checkout for your Fossil project and type: <blockquote> <pre>$ fossil git export /path/to/git/repo --autopush \ https://<font color="orange">username</font>:<font color="red">password</font>@github.com/username/project.git</pre> </blockquote> <p> In place of the <code>/path/to...</code> argument above, put in some directory name that is <i>outside</i> of your Fossil checkout. If you keep multiple Fossil checkouts in a directory of their own, consider using <code>../git-mirror</code> to place the Git export mirror alongside them, for example. Fossil will create this directory if necessary. This directory will become a Git repository that holds a translation of your Fossil repository. <p> The <code>--autopush</code> option tells Fossil that you want to push the Git translation up to GitHub every time it is updated. <p> The URL parameter is the same as the one GitHub gave you, but with your GitHub <font color="orange">username</font> and <font color="red">password</font> added. <p> If your GitHub account uses two-factor authentication (2FA), you will have to <a href="https://github.com/settings/tokens">generate a personal access token</a> and use that in place of your actual password in the URL. This token should have “repo†scope enabled, only. <p> You can also run the command above outside of any open checkout of your project by supplying the “<code>-R repository</code>†option. <li><p>Get some coffee. Depending on the size of your project, the initial "<code>fossil git export</code>" command in the previous step might run for several minutes. <li><p>And you are done! Assuming everything worked, your project is now mirrored on GitHub. <li><p>Whenever you update your project, simply run this command to update the mirror: <blockquote> <pre>$ fossil git export</pre> </blockquote> <p> Unlike with the first time you ran that command, you don’t need the remaining arguments, because Fossil remembers those things. Subsequent mirror updates should usually happen in a fraction of a second. <li><p>To see the status of your mirror, run: <blockquote> <pre>$ fossil git status</pre> </blockquote> </ol> ## Notes: * The mirroring is one-way. If you check in changes on GitHub, those changes will not be reabsorbed by Fossil. There are technical problems that make a two-way mirror all but impossible. This also means that you cannot accept pull requests on GitHub. * The "`fossil git export`" command creates subprocesses that run "`git`" commands, so you must have Git installed on your machine for any of this to work. * The Git repository will have an extra unmanaged top-level directory named "`.mirror_state`" that contains one or more files. Those files are used to store the intermediate state of the translation so that subsequent invocations of "`fossil git export`" will know where you left off the last time and what new content needs to be moved over into Git. Be careful not to mess with the `.mirror_state` directory or any of its contents. Do not put those files under Git management. Do not edit or delete them. * The name of the "trunk" branch is automatically translated into "master" in the Git mirror. * Only check-ins and simple tags are translated to Git. Git does not support wiki or tickets or unversioned content or any of the other features of Fossil that make it so convenient to use, so those other elements cannot be mirrored in Git. * In Git, all tags must be unique. If your Fossil repository has the same tag on two or more check-ins, the tag will only be preserved on the chronologically newest check-in. * There is a [long list of restrictions](https://git-scm.com/docs/git-check-ref-format) on tag and branch names in Git. If any of your Fossil tag or branch names violate these rules, then the names are translated prior to being exported to Git. The translation usually involves converting the offending characters into underscores. <a name='ex1'></a> ## Example GitHub Mirrors As of this writing (2019-03-16) Fossil’s own repository is mirrored on GitHub at: > <https://github.com/drhsqlite/fossil-mirror> In addition, an official Git mirror of SQLite is available: > <https://github.com/sqlite/sqlite> The Fossil source repositories for these mirrors are at <https://www2.fossil-scm.org/fossil> and <https://www2.sqlite.org/src>, respectively. Both repositories are hosted on the same VM at [Linode](https://www.linode.com). On that machine, there is a [cron job](https://linux.die.net/man/8/cron) that runs at 17 minutes after the hour, every hour that does: > /usr/bin/fossil sync -u -R /home/www/fossil/fossil.fossil /usr/bin/fossil sync -R /home/www/fossil/sqlite.fossil /usr/bin/fossil git export -R /home/www/fossil/fossil.fossil /usr/bin/fossil git export -R /home/www/fossil/sqlite.fossil The initial two "sync" commands pull in changes from the primary Fossil repositories for Fossil and SQLite. The last two lines export the changes to Git and push the results up to GitHub. |

You can ignore it for all purposes, but be sure not to accidentally remove it or otherwise damage it - it belongs to fossil, not you. |

Passwords are unique to each repository. Passwords are not part of the persistent state of a project. Passwords are not versioned and are not transmitted from one repository to another during a sync. Passwords are local configuration information that can (and usually does) vary from one repository to the next within the same project. Passwords are stored in the PW field of the USER table. | | | | 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 | <title>Fossil Password Management</title> <h1 align="center">Password Management</h1> Fossil handles user authentication using passwords.

Passwords are local configuration information that can (and usually does) vary from one repository to the next within the same project. Passwords are stored in the PW field of the USER table. In older versions of Fossil (prior to [/timeline?c=2010-01-10T20:56:30 | 2010-01-11]) the password is stored as cleartext. In newer versions of Fossil, the password can be either cleartext or an SHA1 hash (written as a 40-character lower-case hexadecimal number). If the USER.PW field contains a 40-character string, that string is assumed to be a SHA1 hash. If the size of USER.PW is anything other than 40 characters, then it is understood as a plain-text password. |

The server then hashes the password and compares it against the value stored in USER.PW. If they match, the server sets a cookie on the client to record the login. This cookie contains a large amount of high-quality randomness and is thus intractable to guess. The value of the cookie and the IP address of the client is stored in the USER.COOKIE and USER.IPADDR fields | | | | | 69 70 71 72 73 74 75 76 77 78 79 80 81 82 83 84 85 86 | When a user logs into Fossil using the web interface, the login name and password are sent in the clear to the server.

This cookie contains a large amount of high-quality randomness and is thus intractable to guess. The value of the cookie and the IP address of the client is stored in the USER.COOKIE and USER.IPADDR fields of the USER table on the server. The USER.CEXPIRE field holds an expiration date for the cookie, encoded as a Julian day number. On all subsequent HTTP requests, the cookie value is matched against the USER table to enable access to the repository. A login cookie will only work if the IP address matches. This feature is designed to make it more difficult for an attacker to sniff the cookie and take over the connection. A cookie-sniffing attack will only work if the attacker is able to send and receive from the same IP address as the original login. However, we found that doing an exact IP match |

The plan moving forward is to compute the SHA1 hash of the password on the client using JavaScript and then send only the hash over the wire, but that plan has not yet been set in code. <h2>Sync Protocol Authentication</h2> A different authentication mechanism is used when one repository wants to sync (or push or pull or clone) another repository. When two repositories are syncing, the one that initiates the transaction is the client and the repository that responds is the server. The client works by sending HTTP requests to the server with a method of "xfer" and a content-type of "application/x-fossil". The content is Zlib-compressed text consisting of "cards" of instructions. The first card of this content is a "login" card responsible for authentication. The login card contains the login name of the user and a "signature" where the signature is the SHA1 hash of a nonce and the value of USER.PW. The nonce is the |

If the USER.PW on the server only holds the SHA1 hash of the password, then only newer clients will be able to authenticate to the server. The client normally gets the login and password from the "remote URL". <blockquote><pre> | | | | | | 131 132 133 134 135 136 137 138 139 140 141 142 143 144 145 146 147 148 149 150 151 152 153 154 155 | will work for both older and newer clients. If the USER.PW on the server only holds the SHA1 hash of the password, then only newer clients will be able to authenticate to the server. The client normally gets the login and password from the "remote URL". <blockquote><pre> http://<span style="color:blue">login:password</span>@servername.org/path </pre></blockquote> For older clients, the password is used for the shared secret as stated in the URL and with no encoding. For newer clients, the shared secret is derived from the password by transformed the password using the SHA1 hash encoding described above. However, if the first character of the password is "*" (ASCII 0x2a) then the "*" is skipped and the rest of the password is used directly as the share secret without the SHA1 encoding. <blockquote><pre> http://<span style="color:blue">login:*password</span>@servername.org/path </pre></blockquote> This *-before-the-password trick can be used by newer clients to sync against a legacy server that does not understand the new SHA1 password encoding. |

All historical copies of all artifacts are saved. The project maintains an audit trail.</p></li> <li><p>A project resides in one or more repositories. Each repository is administered and operates independently of the others.</p></li> <li><p>Each repository has both global and local state. The global state is common to all repositories (or at least has the potential to be shared in common when the repositories are fully synchronized). The local state for each repository is private to that repository. The global state represents the content of the project. The local state identifies the authorized users and access policies for a particular repository.</p></li> <li><p>The global state of a repository is an unordered collection of artifacts. Each artifact is named by a cryptographic hash (SHA1 or SHA3-256) encoded in lowercase hexadecimal. In many contexts, the name can be abbreviated to a unique prefix. A five- or six-character prefix usually suffices to uniquely identify a file.</p></li> <li><p>Because artifacts are named by a cryptographic hash, all artifacts are immutable. Any change to the content of an artifact also changes the hash that forms the artifacts name, thus creating a new artifact. Both the old original version of the artifact and the new change are preserved under different names.</p></li> <li><p>It is theoretically possible for two artifacts with different content to share the same hash. But finding two such artifacts is so incredibly difficult and unlikely that we consider it to be an impossibility.</p></li> <li><p>The signature of an artifact is the cryptographic hash of the artifact itself, exactly as it would appear in a disk file. No prefix or meta-information about the artifact is added before computing the hash. So you can always find the signature of a file by using the "sha1sum" or "sha3sum" or similar command-line utilities.</p></li> <li><p>The artifacts that comprise the global state of a repository are the complete global state of that repository. The SQLite database that holds the repository contains additional information about linkages between artifacts, but all of that added information can be discarded and reconstructed by rescanning the content artifacts.</p></li> |

That branch will not participate in subsequent clone, sync, push, or pull operations. The branch will remain on the one local repository where it was created. Note that you only use the --private option for the first check-in that creates the private branch. Additional checkins into the private branch remain private automatically. <h2>Publishing Private Changes</h2> After additional work, one might desire to publish the changes associated with a private branch. The usual way to do this is to merge those changes into a public branch. For example: <blockquote><pre> fossil update trunk fossil merge private fossil commit </pre></blockquote> The private branch remains private, but all of the changes associated with the private branch are now folded into the public branch and are hence visible to other users of the project. A private branch created with Fossil version 1.30 or newer can also be converted into a public branch using the <code>fossil publish</code> command. However, there is no way to convert a private branch created with older versions of Fossil into a public branch. The <code>--integrate</code> option of <code>fossil merge</code> (to close the merged branch when committing) is ignored for a private branch -- or the check-in manifest of the resulting merge child would include a <code>+close</code> tag referring to the leaf check-in on the private branch, and generate a missing artifact reference on repository clones without that private branch. It's still possible to close the leaf of the private branch (after committing the merge child) with the <code>fossil amend --close</code> command. <h2>Syncing Private Branches</h2> A private branch normally stays on the one repository where it was originally created. But sometimes you want to share private branches with another repository. For example, you might be building a cross-platform application and have separate repositories on your Windows laptop, your Linux desktop, and your iMac. You can transfer private branches between these machines by using the --private option on the "sync", "push", "pull", and "clone" commands. For example, if you are running "fossil server" on your Linux box and you want to clone that repository to your Mac, including all private branches, use: <blockquote><pre> fossil clone --private http://user@linux.localnetwork:8080/ mac-clone.fossil </pre></blockquote> You'll have to supply a username and password in order for this to work. Fossil will not clone (or sync) private branches anonymously. By default, there are no users that can do private branch syncing. You will have to give a user the "Private" capability ("x") if you want them to be able to do this. We deny such capability for normal users by default to add a barrier to accidental syncing of a private branch to a public server. It is highly recommended that you leave the "x" capability turned off on all repositories used for collaboration (repositories to which many people push and pull) and only enable "x" for local repositories when you need to share private branches. Private branch sync only works if you use the --private command-line option. Private branches are never synced via the auto-sync mechanism. Once again, this restriction is designed to make it hard to accidentally push private branches beyond their intended audience. <h2>Purging Private Branches</h2> You can remove all private branches from a repository using this command: <blockquote><pre> fossil scrub --private </pre></blockquote> Note that the above is a permanent and irreversible change. You will be asked to confirm before continuing. Once the private branches are removed, they cannot be retrieved (unless you have synced them to another repository.) So be careful with the command. <h2>Additional Notes</h2> All of the features above apply to <u>all</u> private branches in a single repository at once. There is no mechanism in Fossil (currently) that allows you to push, pull, clone, sync, or scrub an individual private branch within a repository that contains multiple private branches. |

This page is old and has not been kept up-to-date. See the </nowiki>[/finfo?name=www/qandc.wiki|change history of this page]<nowiki>.</p> <b>Fossil sounds like a lot of reinvention of the wheel. Why create your own DVCS when you could have reused mercurial?</b> <blockquote> <p>I wrote fossil because none of the other available DVCSes met my needs. If the other DVCSes do meet your needs, then you might not need fossil. But they don't meet mine, and so fossil is necessary for me.</p> <p>Features provided by fossil that one does not get with other DVCSes include:</p> <ol> <li> Integrated <a href="wikitheory.wiki">wiki</a>. </li> <li> Integrated <a href="bugtheory.wiki">bug tracking</a> </li> <li> Immutable artifacts </li> <li> Self-contained, stand-alone executable that can be run in a <a href="http://en.wikipedia.org/wiki/Chroot">chroot jail</a> </li> <li> Simple, well-defined, <a href="fileformat.wiki">enduring file format</a> </li> <li> Integrated <a href="webui.wiki">web interface</a> </li> </ol> </blockquote> <b>Why should I use this rather than Trac?</b> <blockquote> <ol> <li> Fossil is distributed. You can view and/or edit tickets, wiki, and code while off network, then sync your changes later. With Trac, you can only view and edit tickets and wiki while you are connected to the server. </li> <li> Fossil is lightweight and fully self-contained. It is very easy to setup on a low-resource machine. Fossil does not require an administrator.</li> <li> Fossil integrates code versioning into the same repository with wiki and tickets. There is nothing extra to add or install. Fossil is an all-in-one turnkey solution. </li> </ol> </blockquote> <b>Love the concept here. Anyone using this for real work yet?</b> <blockquote> Fossil is <a href="http://www.fossil-scm.org/">self-hosting</a>. In fact, this page was probably delivered to your web-browser via a working fossil instance. The same virtual machine that hosts http://www.fossil-scm.org/ (a <a href="http://www.linode.com/">Linode 720</a>) also hosts 24 other fossil repositories for various small projects. The documentation files for <a href="http://www.sqlite.org/">SQLite</a> are hosted in a fossil repository <a href="http://www.sqlite.org/docsrc/">here</a>, for example. Other projects are also adopting fossil. But fossil does not yet have the massive user base of git or mercurial. </blockquote> <b>Fossil looks like the bug tracker that would be in your Linksys Router's administration screen.</b> <blockquote> <p>I take a pragmatic approach to software: form follows function. To me, it is more important to have a reliable, fast, efficient, enduring, and simple DVCS than one that looks pretty.</p> <p>On the other hand, if you have patches that improve the appearance of Fossil without seriously compromising its reliability, performance, and/or maintainability, I will be happy to accept them. Fossil is self-hosting. Send email to request a password that will let you push to the main fossil repository.</p> </blockquote> <b>It would be useful to have a separate application that keeps the bug-tracking database in a versioned file. That file can then be pushed and pulled along with the rest repository.</b> <blockquote> <p>Fossil already <u>does</u> push and pull bugs along with the files in your repository. But fossil does <u>not</u> track bugs as files in the source tree. That approach to bug tracking was rejected for three reasons:</p> <ol> <li> Check-ins in fossil are immutable. So if tickets were part of the check-in, then there would be no way to add new tickets to a check-in as new bugs are discovered. |

But that is not the point. Fossil has several key features that Trac lacks and that I need: most notably the fact that fossil supports disconnected operation.</p> <p>As for bloat: Fossil is a single self-contained executable. You do not need any other packages (diff, patch, merge, cvs, svn, rcs, git, python, perl, tcl, apache, sqlite, and so forth) in order to run fossil. Fossil runs just fine in a chroot jail all by itself. And the self-contained fossil executable is much less than 1MB in size. (Update 2015-01-12: Fossil has grown in the years since the previous sentence was written but is still much less than 2MB according to "size" when compiled using -Os on x64 Linux.) Fossil is the very opposite of bloat.</p> </blockquote> </nowiki> |

You need to either download a <a href="https://www.fossil-scm.org/fossil/uv/download.html">precompiled binary</a> or <a href="build.wiki">compile it yourself</a> from sources. Install Fossil by putting the fossil binary someplace on your $PATH.</p> <a name="fslclone"></a> <h2>General Work Flow</h2> <p>Fossil works with repository files (a database with the project's complete history) and with checked-out local trees (the working directory you use to do your work). (See [./whyusefossil.wiki#definitions | definitions] for more background.) The workflow looks like this:</p> <ul> <li>Create or clone a repository file. ([/help/init|fossil init] or [/help/clone | fossil clone]) <li>Check out a local tree. ([/help/open | fossil open]) <li>Perform operations on the repository (including repository configuration). </ul> <p>The following sections will give you a brief overview of these operations.</p> <h2>Starting A New Project</h2> <p>To start a new project with fossil, create a new empty repository this way: ([/help/init | more info]) </p> <blockquote> <b>fossil init </b><i> repository-filename</i> </blockquote> <h2>Cloning An Existing Repository</h2> <p>Most fossil operations interact with a repository that is on the local disk drive, not on a remote system. Hence, before accessing a remote repository it is necessary to make a local copy of that repository. Making a local copy of a remote repository is called "cloning".</p> <p>Clone a remote repository as follows: ([/help/clone | more info])</p> <blockquote> <b>fossil clone</b> <i>URL repository-filename</i> </blockquote> <p>The <i>URL</i> specifies the fossil repository you want to clone. The <i>repository-filename</i> is the new local filename into which the cloned repository will be written. For example: <blockquote> <b>fossil clone http://www.fossil-scm.org/ myclone.fossil</b> </blockquote> <p>If the remote repository requires a login, include a userid in the URL like this: <blockquote> <b>fossil clone http://</b><i>userid</i><b>@www.fossil-scm.org/ myclone.fossil</b> </blockquote> <p>You will be prompted separately for the password. Use "%HH" escapes for special characters in the userid. Examples: "%40" in place of "@" and "%2F" in place of "/". <p>If you are behind a restrictive firewall, you might need to <a href="#proxy">specify an HTTP proxy</a>.</p> <p>A Fossil repository is a single disk file. Instead of cloning, you can just make a copy of the repository file (for example, using "scp"). Note, however, that the repository file contains auxiliary information above and beyond the versioned files, including some sensitive information such as password hashes and email addresses. If you want to share Fossil repositories directly, consider running the [/help/scrub|fossil scrub] command to remove sensitive information before transmitting the file. <h2>Importing From Another Version Control System</h2> <p>Rather than start a new project, or clone an existing Fossil project, you might prefer to <a href="./inout.wiki">import an existing Git project</a> into Fossil using the [/help/import | fossil import] command. <h2>Checking Out A Local Tree</h2> <p>To work on a project in fossil, you need to check out a local copy of the source tree. Create the directory you want to be the root of your tree and cd into that directory. Then do this: ([/help/open | more info])</p> <blockquote> <b>fossil open </b><i> repository-filename</i> </blockquote> <p>This leaves you with the newest version of the tree checked out. From anywhere underneath the root of your local tree, you can type commands like the following to find out the status of your local tree:</p> <blockquote> <b>[/help/info | fossil info]</b><br> <b>[/help/status | fossil status]</b><br> <b>[/help/changes | fossil changes]</b><br> <b>[/help/diff | fossil diff]</b><br> <b>[/help/timeline | fossil timeline]</b><br> <b>[/help/ls | fossil ls]</b><br> <b>[/help/branch | fossil branch]</b><br> </blockquote> <p>Note that Fossil allows you to make multiple check-outs in separate directories from the same repository. This enables you, for example, to do builds from multiple branches or versions at the same time without having to generate extra clones.</p> <p>To switch a checkout between different versions and branches, use:</p> <blockquote> <b>[/help/update | fossil update]</b><br> <b>[/help/checkout | fossil checkout]</b><br> </blockquote> <p>[/help/update | update] honors the "autosync" option and does a "soft" switch, merging any local changes into the target version, whereas [/help/checkout | checkout] does not automatically sync and does a "hard" switch, overwriting local changes if told to do so.</p> <h2>Configuring Your Local Repository</h2> <p>When you create a new repository, either by cloning an existing project or create a new project of your own, you usually want to do some local configuration. This is easily accomplished using the web-server that is built into fossil. Start the fossil web server like this: ([/help/ui | more info])</p> <blockquote> <b>fossil ui </b><i> repository-filename</i> </blockquote> <p>You can omit the <i>repository-filename</i> from the command above if you are inside a checked-out local tree.</p> <p>This starts a web server then automatically launches your web browser and makes it point to this web server. If your system has an unusual configuration, fossil might not be able to figure out how to start your web browser. In that case, first tell fossil where to find your web browser using a command like this:</p> <blockquote> <b>fossil setting web-browser </b><i> path-to-web-browser</i> </blockquote> <p>By default, fossil does not require a login for HTTP connections coming in from the IP loopback address 127.0.0.1. You can, and perhaps should, change this after you create a few users.</p> <p>When you are finished configuring, just press Control-C or use the <b>kill</b> command to shut down the mini-server.</p> <h2>Making Changes</h2> <p>To add new files to your project, or remove old files, use these commands:</p> <blockquote> <b>[/help/add | fossil add]</b> <i>file...</i><br> <b>[/help/rm | fossil rm]</b> <i>file...</i><br> <b>[/help/addremove | fossil addremove]</b> <i>file...</i><br> </blockquote> <p>You can also edit files freely. Once you are ready to commit your changes, type:</p> <blockquote> <b>[/help/commit | fossil commit]</b> </blockquote> <p>You will be prompted for check-in comments using whatever editor is specified by your VISUAL or EDITOR environment variable.</p> In the default configuration, the [/help/commit|commit] command will also automatically [/help/push|push] your changes, but that feature can be disabled. (More information about [./concepts.wiki#workflow|autosync] and how to disable it.) Remember that your coworkers can not see your changes until you commit and push them.</p> <h2>Sharing Changes</h2> <p>When [./concepts.wiki#workflow|autosync] is turned off, the changes you [/help/commit | commit] are only on your local repository. To share those changes with other repositories, do:</p> <blockquote> <b>[/help/push | fossil push]</b> <i>URL</i> </blockquote> |

([./checkin_names.wiki | more info]) If you omit the <i>VERSION</i>, then fossil moves you to the latest version of the branch your are currently on.</p> <p>The default behavior is for [./concepts.wiki#workflow|autosync] to be turned on. That means that a [/help/pull|pull] automatically occurs when you run [/help/update|update] and a [/help/push|push] happens automatically after you [/help/commit|commit]. So in normal practice, the push, pull, and sync commands are rarely used. But it is important to know about them, all the same.</p> <blockquote> <b>[/help/checkout | fossil checkout]</b> <i>VERSION</i> </blockquote> <p>Is similar to update except that it does not honor the autosync setting, nor does it merge in local changes - it prefers to overwrite them and fails if local changes exist unless the <tt>--force</tt> flag is used.</p> <h2>Branching And Merging</h2> <p>Use the --branch option to the [/help/commit | commit] command to start a new branch. Note that in Fossil, branches are normally created when you commit, not before you start editing. You can use the [/help/branch | branch new] command to create a new branch before you start editing, if you want, but most people just wait until they are ready to commit. To merge two branches back together, first [/help/update | update] to the branch you want to merge into. Then do a [/help/merge|merge] of the other branch that you want to incorporate the changes from. For example, to merge "featureX" changes into "trunk" do this:</p> <blockquote> <b>fossil [/help/update|update] trunk</b><br> <b>fossil [/help/merge|merge] featureX</b><br> <i># make sure the merge didn't break anything...</i><br> <b>fossil [/help/commit|commit] </blockquote> <p>The argument to the [/help/merge|merge] command can be any of the version identifier forms that work for [/help/update|update]. ([./checkin_names.wiki|more info].) The merge command has options to cherry-pick individual changes, or to back out individual changes, if you don't want to do a full merge.</p> The merge command puts all changes in your working check-out. No changes are made to the repository. You must run [/help/commit|commit] separately to add the merge changes into your repository to make them persistent and so that your coworkers can see them. But before you do that, you will normally want to run a few tests to verify that the merge didn't cause logic breaks in your code. The same branch can be merged multiple times without trouble. Fossil automatically keeps up with things and avoids conflicts when doing multiple merges. So even if you have merged the featureX branch into trunk previously, you can do so again and Fossil will automatically know to pull in only those changes that have occurred since the previous merge. <p>If a merge or update doesn't work out (perhaps something breaks or there are many merge conflicts) then you back up using:</p> <blockquote> <b>[/help/undo | fossil undo]</b> </blockquote> <p>This will back out the changes that the merge or update made to the working checkout. There is also a [/help/redo|redo] command if you undo by mistake. Undo and redo only work for changes that have not yet been checked in using commit and there is only a single level of undo/redo.</p> <h2>Setting Up A Server</h2> <p>Fossil can act as a stand-alone web server using one of these commands:</p> <blockquote> <b>[/help/server | fossil server]</b> <i>repository-filename</i><br> <b>[/help/ui | fossil ui]</b> <i>repository-filename</i> </blockquote> <p>The <i>repository-filename</i> can be omitted when these commands are run from within an open check-out, which a particularly useful shortcut for the <b>fossil ui</b> command. <p>The <b>ui</b> command is intended for accessing the web interface from a local desktop. The <b>ui</b> command binds to the loopback IP address only (and thus makes the web interface visible only on the local machine) and it automatically start your web browser pointing at the server. For cross-machine collaboration, use the <b>server</b> command, which binds on all IP addresses and does not try to start a web browser.</p> <p>Servers are also easily configured as: <ul> <li>[./server/any/inetd.md|inetd] <li>[./server/debian/service.md|systemd] <li>[./server/any/cgi.md|CGI] <li>[./server/any/scgi.md|SCGI] </ul> <p>The [./selfhost.wiki | self-hosting fossil repositories] use CGI. <a name="proxy"></a> <h2>HTTP Proxies</h2> <p>If you are behind a restrictive firewall that requires you to use an HTTP proxy to reach the internet, then you can configure the proxy in three different ways. You can tell fossil about your proxy using |
︙ | ︙ | |||
335 336 337 338 339 340 341 | </blockquote> <p>Or unset the environment variable. The fossil setting for the HTTP proxy takes precedence over the environment variable and the command-line option overrides both. If you have an persistent proxy setting that you want to override for a one-time sync, that is easily done on the command-line. For example, to sync with | | | | | > > > > > | | 383 384 385 386 387 388 389 390 391 392 393 394 395 396 397 398 399 400 401 402 403 404 405 | </blockquote> <p>Or unset the environment variable. The fossil setting for the HTTP proxy takes precedence over the environment variable and the command-line option overrides both. If you have an persistent proxy setting that you want to override for a one-time sync, that is easily done on the command-line. For example, to sync with a co-workers repository on your LAN, you might type:</p> <blockquote> <b>fossil sync http://192.168.1.36:8080/ --proxy off</b> </blockquote> <h2 id="links">Other Resources</h2> <ul> <li> <a href="./gitusers.md">Hints for users with prior Git experience</a> <li> <a href="./whyusefossil.wiki">Benefits Of Version Control</a> <li> <a href="./history.md">The Purpose And History of Fossil</a> <li> <a href="./branching.wiki">Branching, Forking, Merge, and Taggings</a> <li> <a href="./hints.wiki">Tips and Usage Hints</a> <li> <a href="./permutedindex.html">Comprehensive documentation index</a> </ul> |

This collection is put together by the creator of Fossil, so of course there is selection bias... <h2>On The Usability Of Git:</h2> <ol> <li>Git approaches the usability of iptables, which is to say, utterly unusable unless you have the manpage tattooed on you arm. <blockquote> <i>by mml at [http://news.ycombinator.com/item?id=1433387]</i> </blockquote> <li><nowiki>It's simplest to think of the state of your [git] repository as a point in a high-dimensional "code-space", in which branches are represented as n-dimensional membranes, mapping the spatial loci of successive commits onto the projected manifold of each cloned repository.</nowiki> <blockquote> <i>At [http://tartley.com/?p=1267]</i> </blockquote> <li>Git is not a Prius. Git is a Model T. Its plumbing and wiring sticks out all over the place. You have to be a mechanic to operate it successfully or you'll be stuck on the side of the road when it breaks down. And it <b>will</b> break down. <blockquote> <i>Nick Farina at [http://nfarina.com/post/9868516270/git-is-simpler]</i> </blockquote> <li>Initial revision of "git", The information manager from hell <blockquote> <i>Linus Torvalds - 2005-04-07 22:13:13<br> Commit comment on the very first source-code check-in for git </blockquote> <li>I've been experimenting a lot with git at work. Damn, it's complicated. It has things to trip you up with that sane people just wouldn't ever both with including the ability to allow you to commit stuff in such a way that you can't find it again afterwards (!!!) Demented workflow complexity on acid? <p>* dkf really wishes he could use fossil instead</p> <blockquote> <i>by Donal K. Fellow (dkf) on the Tcl/Tk chatroom, 2013-04-09.</i> </blockquote> <li>Klingon Code Warriors embrace Git; we enjoy arbitrary conflicts. Git is not for the weak and feeble. TODAY IS A GOOD DAY TO CODE. <blockquote> <i>teastain at [http://www.reddit.com/r/programming/comments/xpitj/10_things_i_hate_about_git/c5oj4fk] </blockquote> <li>[G]it is <i>designed</i> to forget things. <blockquote> <i>[http://www.cs.cmu.edu/~davide/howto/git_lose.html] </blockquote> <li>[I]n nearly 31 years of using a computer i have, in total, lost more data to git (while following the instructions!!!) than any other single piece of software. <blockquote> <i>Stephen Beal on the [http://www.mail-archive.com/fossil-users@lists.fossil-scm.org/msg17181.html|Fossil mailing list] 2014-09-01.</i> </blockquote> <li>If programmers _really_ wanted to help scientists, they'd build a version control system that was more usable than Git. <blockquote> <i>Tweet by Greg Wilson @gvwilson on 2015-02-22 17:47</i> </blockquote> <li><img src='xkcd-git.gif' align='top'> <blockquote><i>Randall Munroe. [http://xkcd.com/1597/]</i></blockquote> </ol> <h2>On The Usability Of Fossil:</h2> <ol> <li value=11> Fossil mesmerizes me with simplicity especially after I struggled to get a bug-tracking system to work with mercurial. <blockquote> <i>rawjeev at [http://stackoverflow.com/questions/156322/what-do-people-think-of-the-fossil-dvcs]</i> </blockquote> <li>Fossil is the best thing to happen to my development workflow this year, as I am pretty sure that using Git has resulted in the premature death of too many of my brain cells. I'm glad to be able to replace Git in every place that I possibly can with Fossil. <blockquote> <i>Joe Prostko at [http://www.mail-archive.com/fossil-users@lists.fossil-scm.org/msg16716.html] </blockquote> <li>Fossil is awesome!!! I have never seen an app like that before, such simplicity and flexibility!!! <blockquote> <i>zengr at [http://stackoverflow.com/questions/138621/best-version-control-for-lone-developer]</i> </blockquote> <li>This is my favourite VCS. I can carry it on a USB. And it's a complete system, with it's own server, ticketing system, Wiki pages, and a very, very helpful timeline visualization. And the entire program in a single file! <blockquote> <i>thunderbong commenting on hacker news: [https://news.ycombinator.com/item?id=9131619]</i> </blockquote> </ol> <h2>On Git Versus Fossil</h2> <ol> <li value=15> After prolonged exposure to fossil, i tend to get the jitters when I work with git... <blockquote> <i>sriku - at [https://news.ycombinator.com/item?id=16104427]</i> </blockquote> <li> Just want to say thanks for fossil making my life easier.... Also <nowiki>[for]</nowiki> not having a misanthropic command line interface. <blockquote> <i>Joshua Paine at [http://www.mail-archive.com/fossil-users@lists.fossil-scm.org/msg02736.html]</i> </blockquote> <li>We use it at a large university to manage code that small teams write. The runs everywhere, ease of installation and portability is something that seems to be a good fit with the environment we have (highly ditrobuted, sometimes very restrictive firewalls, OSX/Win/Linux). We are happy with it and teaching a Msc/Phd student (read complete novice) fossil has just been a smoother ride than Git was. <blockquote> <i>viablepanic at [http://www.reddit.com/r/programming/comments/bxcto/why_not_fossil_scm/]</i> </blockquote> <li>In the fossil community - and hence in fossil itself - development history is pretty much sacrosanct. The very name "fossil" was to chosen to reflect the unchanging nature of things in that history. <p>In git (or rather, the git community), the development history is part of the published aspect of the project, so it provides tools for rearranging that history so you can present what you "should" have done rather than what you actually did. <blockquote> <i>Mike Meyer on the Fossil mailing list, 2011-10-04</i> </blockquote> <li>github is such a pale shadow of what fossil does. <blockquote> <i>dkf on the Tcl chatroom, 2013-12-06</i> </blockquote> </ol> |

This article attempts to explain that point of view. [vhist]: /finfo?name=www/rebaseharm.md&ubg ## 1.0 Rebasing is dangerous Most people, even strident advocates of rebase, agree that rebase can cause problems when misused. The Git rebase documentation talks about the [golden rule of rebasing][golden]: never rebase on a public branch. Horror stories of misused rebase abound, and the rebase documentation devotes considerable space toward explaining how to recover from rebase errors and/or misuse. ## <a name="cap-loss"></a>2.0 Rebase provides no new capabilities Sometimes sharp and dangerous tools are justified, because they accomplish things that cannot be done otherwise, or at least cannot be done easily. Rebase does not fall into that category, because it provides no new capabilities. ### <a name="orphaning"></a>2.1 A rebase is just a merge with historical references omitted A rebase is really nothing more than a merge (or a series of merges) that deliberately forgets one of the parents of each merge step. To help illustrate this fact, consider the first rebase example from the [Git documentation][gitrebase]. The merge looks like this: ![merge case](./rebase01.svg) And the rebase looks like this: ![rebase case](./rebase02.svg) As the [Git documentation][gitrebase] points out, check-ins C4\' and C5 are identical. The only difference between C4\' and C5 is that C5 records the fact that C4 is its merge parent but C4\' does not. Thus, a rebase is just a merge that forgets where it came from. The Git documentation acknowledges this fact (in so many words) and justifies it by saying "rebasing makes for a cleaner history." I read that sentence as a tacit admission that the Git history display capabilities are weak and need active assistance from the user to keep things manageable. Surely a better approach is to record the complete ancestry of every check-in but then fix the tool to show a "clean" history in those instances where a simplified display is desirable and edifying, but retain the option to show the real, complete, messy history for cases where detail and accuracy are more important. So, another way of thinking about rebase is that it is a kind of merge that intentionally forgets some details in order to not overwhelm the weak history display mechanisms available in Git. Wouldn't it be better, less error-prone, and easier on users to enhance the history display mechanisms in Git so that rebasing for a clean, linear history became unnecessary? ### <a name="clean-diffs"></a>2.2 Rebase does not actually provide better feature-branch diffs Another argument, often cited, is that rebasing a feature branch allows one to see just the changes in the feature branch without the concurrent changes in the main line of development. Consider a hypothetical case: ![unmerged feature branch](./rebase03.svg) In the above, a feature branch consisting of check-ins C3 and C5 is run concurrently with the main line in check-ins C4 and C6. Advocates for rebase say that you should rebase the feature branch to the tip of main in order to remove main-line development differences from the feature branch's history: ![rebased feature branch](./rebase04.svg) You could choose to collapse C3\' and C5\' into a single check-in as part of this rebase, but that's a side issue we'll deal with [separately](#collapsing). Because Fossil purposefully lacks rebase, the closest you can get to this same check-in history is the following merge: ![merged feature branch](./rebase05.svg) Check-ins C5\' and C7 check-ins hold identical code. The only difference is in their history. The argument from rebase advocates is that with merge it is difficult to see only the changes associated with the feature branch without the commingled mainline changes. In other words, diff(C2,C7) shows changes from both the feature branch and from the mainline, whereas in the rebase case diff(C6,C5\') shows only the feature branch changes. But that argument is comparing apples to oranges, since the two diffs do not have the same baseline. The correct way to see only the feature branch changes in the merge case is not diff(C2,C7) but rather diff(C6,C7). <center><table border="1" cellpadding="5" cellspacing="0"> <tr><th>Rebase<th>Merge<th>What You See <tr><td>diff(C2,C5\')<td>diff(C2,C7)<td>Commingled branch and mainline changes <tr><td>diff(C6,C5\')<td>diff(C6,C7)<td>Branch changes only </table></center> Remember: C7 and C5\' are bit-for-bit identical, so the output of the diff is not determined by whether you select C7 or C5\' as the target of the diff, but rather by your choice of the diff source, C2 or C6. So, to help with the problem of viewing changes associated with a feature branch, perhaps what is needed is not rebase but rather better tools to help users identify an appropriate baseline for their diffs. ## <a name="siloing"></a>3.0 Rebase encourages siloed development The [golden rule of rebasing][golden] is that you should never do it on public branches, so if you are using rebase as intended, that means you are keeping private branches. Or, to put it another way, you are doing siloed development. You are not sharing your intermediate work with collaborators. This is not good for product quality. [Nagappan, et. al][nagappan] studied bugs in Windows Vista and found that best predictor of bugs is the distance on the org-chart between the stake-holders. The bug rate is inversely related to the amount of communication among the engineers. Similar findings arise in other disciplines. Keeping private branches does not prove that developers are communicating insufficiently, but it is a key symptom that problem. [Weinberg][weinberg] argues programming should be "egoless." That is to say, programmers should avoid linking their code with their sense of self, as that makes it more difficult for them to find and respond to bugs, and hence makes them less productive. Many developers are drawn to private branches out of sense of ego. "I want to get the code right before I publish it." I sympathize with this sentiment, and am frequently guilty of it myself. It is humbling to display your stupid mistake to the whole world on an Internet that never forgets. And yet, humble programmers generate better code. What is the fastest path to solid code? Is it to continue staring at your private branch to seek out every last bug, or is it to publish it as-is, whereupon the many eyeballs will immediately see that last stupid error in the code? Testing and development are often done by separate groups within a larger software development organization, because developers get too close to their own code to see every problem in it. Given that, is it better for those many eyeballs to find your problems while they're still isolated on a feature branch, or should that vetting wait until you finally push a collapsed version of a private working branch to the parent repo? Will the many eyeballs even see those errors when they’re intermingled with code implementing some compelling new feature? ## <a name="testing"></a>4.0 Rebase commits untested check-ins to the blockchain Rebase adds new check-ins to the blockchain without giving the operator an opportunity to test and verify those check-ins. Just because the underlying three-way merge had no conflict does not mean that the resulting code actually works. Thus, rebase runs the very real risk of adding non-functional check-ins to the permanent record. Of course, a user can also commit untested or broken check-ins without the help of rebase. But at least with an ordinary commit or merge (in Fossil at least), the operator has the *opportunity* to test and verify the merge before it is committed, and a chance to back out or fix the change if it is broken without leaving busted check-ins on the blockchain to complicate future bisects. With rebase, pre-commit testing is not an option. ## <a name="timestamps"></a>5.0 Rebase causes timestamp confusion Consider the earlier example of rebasing a feature branch: ![rebased feature branch, again](./rebase04.svg) What timestamps go on the C3\' and C5\' check-ins? If you choose the same timestamps as the original C3 and C5, then you have the odd situation C3' is older than its parent C6. We call that a "timewarp" in Fossil. Timewarps can also happen due to misconfigured system clocks, so they are not unique to rebase, but they are very confusing and so best avoided. The other option is to provide new unique timestamps for C3' and C5' but then you lose the information about when those check-ins were originally created, which can make historical analysis of changes more difficult. It might also complicate the legal defense of prior art claims. ## <a name="lying"></a>6.0 Rebasing is lying about the project history By discarding parentage information, rebase attempts to deceive the reader about how the code actually came together. The [Git rebase documentation][gitrebase] admits as much. They acknowledge that when you view a repository as record of what actually happened, doing a rebase is "blasphemous" and "you're _lying_ about what actually happened", but then goes on to justify rebase as follows: > _"The opposing point of view is that the commit history is the **story of how your project was made.** You wouldn't publish the first draft of a book, and the manual for how to maintain your software deserves careful editing. This is the camp that uses tools like rebase and filter-branch to tell the story in the way that's best for future readers."_ This counter-argument assumes you must change history in order to enhance readability, which is not true. In fairness to the Git documentation authors, changing the project history appears to be the only way to make editorial changes in Git. But it does not have to be that way. Fossil demonstrates how "the story of your project" can be enhanced without changing the actual history by allowing users to: 1. Edit check-in comments to fix typos or enhance clarity 2. Attach supplemental notes to check-ins or whole branches 3. Cross-reference check-ins with each other, or with wiki, tickets, forum posts, and/or embedded documentation 4. Cause mistaken or unused branches to be hidden from routine display 5. Fix faulty check-in date/times resulting from misconfigured system clocks 6. And so forth.... These changes are accomplished not by removing or modifying existing repository entries, but rather by adding new supplemental records. The original incorrect or unclear inputs are preserved and are readily accessible. The original history is preserved. But for routine display purposes, the more readable edited presentation is provided. A repository can be a true and accurate representation of history even without getting everything perfect on the first draft. Those are not contradictory goals, at least not in theory. Unfortunately, Git does not currently provide the ability to add corrections or clarifications or supplimental notes to historical check-ins. Hence, once again, rebase can be seen as an attempt to work around limitations of Git. Git could be enhanced to support editorial changes to check-ins. Wouldn't it be better to fix the version control tool rather than requiring users to fabricate a fictitious project history? ## <a name="collapsing"></a>7.0 Collapsing check-ins throws away valuable information One of the oft-cited advantages of rebasing in Git is that it lets you collapse multiple check-ins down to a single check-in to make the development history “clean.†The intent is that development appear as though every feature were created in a single step: no multi-step evolution, no back-tracking, no false starts, no mistakes. This ignores actual developer psychology: ideas rarely spring forth from fingers to files in faultless finished form. A wish for collapsed, finalized check-ins is a wish for a counterfactual situation. The common counterargument is that collapsed check-ins represent a better world, the ideal we're striving for. What that argument overlooks is that we must throw away valuable information to get there. ### <a name="empathy"></a>7.1 Individual check-ins support developer empathy Ideally, future developers of our software can understand every feature in it using only context available in the version of the code they start work with. Prior to widespread version control, developers had no choice but to work that way. Pre-existing codebases could only be understood as-is or not at all. Developers in that world had an incentive to develop software that was easy to understand retrospectively, even if they were selfish people, because they knew they might end up being those future developers! Yet, sometimes we come upon a piece of code that we simply cannot understand. If you have never asked yourself, "What was this code's developer thinking?" you haven't been developing software for very long. When a developer can go back to the individual check-ins leading up to the current code, they can work out the answers to such questions using only the level of empathy necessary to be a good developer. To understand such code using only the finished form, you are asking future developers to make intuitive leaps that the original developer was unable to make. In other words, you are asking your future maintenance developers to be smarter than the original developers! That's a beautiful wish, but there's a sharp limit to how far you can carry it. Eventually you hit the limits of human brilliance. When the operation of some bit of code is not obvious, both Fossil and Git let you run a [`blame`](/help?cmd=blame) on the code file to get information about each line of code, and from that which check-in last touched a given line of code. If you squash the check-ins on a branch down to a single check-in, you throw away the information leading up to that finished form. Fossil not only preserves the check-ins surrounding the one that included the line of code you're trying to understand, its [superior data model][sdm] lets you see the surrounding check-ins in both directions; not only what lead up to it, but what came next. Git can't do that short of crawling the block-chain backwards from the tip of the branch to the check-in you’re looking at, an expensive operation. We believe it is easier to understand a line of code from the 10-line check-in it was a part of — and then to understand the surrounding check-ins as necessary — than it is to understand a 500-line check-in that collapses a whole branch's worth of changes down to a single finished feature. [sdm]: ./fossil-v-git.wiki#durable ### <a name="bisecting"></a>7.2 Bisecting works better on small check-ins Git lets a developer write a feature in ten check-ins but collapse it down to an eleventh check-in and then deliberately push only that final collapsed check-in to the parent repo. Someone else may then do a bisect that blames the merged check-in as the source of the problem they’re chasing down; they then have to manually work out which of the 10 steps the original developer took to create it to find the source of the actual problem. An equivalent push in Fossil will send all 11 check-ins to the parent repository so that a later investigator doing the same sort of bisect sees the complete check-in history. That bisect will point the investigator at the single original check-in that caused the problem. ### <a name="comments"></a>7.3 Multiple check-ins require multiple check-in comments The more comments you have from a given developer on a given body of code, the more concise documentation you have of that developer's thought process. To resume the bisecting example, a developer trying to work out what the original developer was thinking with a given change will have more success given a check-in comment that explains what the one check-in out of ten blamed by the "bisect" command was trying to accomplish than if they must work that out from the eleventh check-in's comment, which only explains the "clean" version of the collapsed feature. ### <a name="cherrypicking"></a>7.4 Cherry-picks work better with small check-ins While working on a new feature in one branch, you may come across a bug in the pre-existing code that you need to fix in order for work on that feature to proceed. You could choose to switch briefly back to the parent branch, develop the fix there, check it in, then merge the parent back up to the feature branch in order to continue work, but that's distracting. If the fix isn't for a critical bug, fixing it on the parent branch can wait, so it's better to maintain your mental working state by fixing the problem in place on the feature branch, then check the fix in on the feature branch, resume work on the feature, and later merge that fix down into the parent branch along with the feature. But now what happens if another branch *also* needs that fix? Let us say our code repository has a branch for the current stable release, a development branch for the next major version, and feature branches off of the development branch. If we rebase each feature branch down into the development branch as a single check-in, pushing only the rebase check-in up to the parent repo, only that fix's developer has the information locally to perform the cherry-pick of the fix onto the stable branch. Developers working on new features often do not care about old stable versions, yet that stable version may have an end user community that depends on that version, who either cannot wait for the next stable version or who wish to put off upgrading to it for some time. Such users want backported bug fixes, yet the developers creating those fixes have poor incentives to provide those backports. Thus the existence of maintenance and support organizations, who end up doing such work. (There is [a famous company][rh] that built a multi-billion dollar enterprise on such work.) This work is far easier when each cherry-pick transfers completely and cleanly from one branch to another, and we increase the likelihood of achieving that state by working from the smallest check-ins that remain complete. If a support organization must manually disentangle a fix from a feature check-in, they are likely to introduce new bugs on the stable branch. Even if they manage to do their work without error, it takes them more time to do the cherry-pick that way. [rh]: https://en.wikipedia.org/wiki/Red_Hat ### <a name="backouts"></a>7.5 Back-outs also work better with small check-ins The inverse of the cherry-pick merge is the back-out merge. If you push only a collapsed version of a private working branch up to the parent repo, those working from that parent repo cannot automatically back out any of the individual check-ins that went into that private branch. Others must either manually disentangle the problematic part of your merge check-in or back out the entire feature. ## <a name="better-plan"></a>8.0 Cherry-pick merges work better than rebase Perhaps there are some cases where a rebase-like transformation is actually helpful, but those cases are rare, and when they do come up, running a series of cherry-pick merges achieves the same topology with several advantages: 1. Cherry-pick merges preserve an honest record of history. (They do in Fossil at least. Git's file format does not have a slot to record cherry-pick merge history, unfortunately.) 2. Cherry-picks provide an opportunity to [test each new check-in before it is committed][tbc] to the blockchain 3. Cherry-pick merges are "safe" in the sense that they do not cause problems for collaborators if you do them on public branches. 4. Cherry-picks keep both the original and the revised check-ins, so both timestamps are preserved. [tbc]: ./fossil-v-git.wiki#testing ## <a name="conclusion"></a>9.0 Summary and conclusion Rebasing is an anti-pattern. It is dishonest. It deliberately omits historical information. It causes problems for collaboration. And it has no offsetting benefits. For these reasons, rebase is intentionally and deliberately omitted from the design of Fossil.

You will probably also want to specific an alternative TCP/IP port using --port. For example: <blockquote><pre> fossil server $REPOSITORY --port 9000 --scgi </pre></blockquote> Then configure your SCGI-aware web-server to send SCGI requests to port 9000 on the machine where Fossil is running. A typical configuration for this in Nginx is: <blockquote><pre> location ~ ^/demo_project/ { include scgi_params; scgi_pass localhost:9000; scgi_param SCRIPT_NAME "/demo_project"; scgi_param HTTPS "on"; } </pre></blockquote> Note that Nginx does not normally send either the PATH_INFO or SCRIPT_NAME variables via SCGI, but Fossil needs one or the other. So the configuration above needs to add SCRIPT_NAME. If you do not do this, Fossil returns an error. |

Many bugs have been encountered. But, thanks in large part to the defensive measures described here, no data has been lost. The integrity checks are doing their job well.</p> <h2>Atomic Check-ins With Rollback</h2> The Fossil repository is stored in an <a href="http://www.sqlite.org/">SQLite</a> database file. ([./tech_overview.wiki | Addition information] about the repository file format.) SQLite is very mature and stable and has been in wide-spread use for many years, so we are confident it will not cause repository corruption. SQLite databases do not corrupt even if a program or system crash or power failure occurs in the middle of the update. If some kind of crash does occur in the middle of a change, then all the changes are rolled back the next time that the database is accessed. A check-in operation in Fossil makes many changes to the repository database. But all these changes happen within a single transaction. If something goes wrong in the middle of the commit, even if that something is a power failure or OS crash, then the transaction is rolled back and the database is unchanged. <h2>Verification Of Delta Encodings Prior To Transaction Commit</h2> The content files that comprise the global state of a Fossil repository are stored in the repository as a tree. The leaves of the tree are stored as zlib-compressed BLOBs. Interior nodes are deltas from their descendants. A lot of encoding is going on. There is zlib-compression which is relatively well-tested but still might cause corruption if used improperly. And there is the relatively new [./delta_encoder_algorithm.wiki | delta-encoding mechanism] designed expressly for Fossil. We want to make sure that bugs in these encoding mechanisms do not lead to loss of data. To increase our confidence that everything in the repository is recoverable, Fossil makes sure it can extract an exact replica of every content file that it changes just prior to transaction commit. So during the course of check-in (or other repository operation) many different files in the repository might be modified. Some files are simply compressed. Other files are delta encoded and then compressed. While all this is going on, Fossil makes a record of every file and the SHA1 or SHA3-256 hash of the original content of that file. Then just before transaction commit, Fossil re-extracts the original content of all files that were written, recomputes the hash, and verifies that the recomputed hash still matches. If anything does not match up, an error message is printed and the transaction rolls back. So, in other words, Fossil always checks to make sure it can re-extract a file before it commits a change to that file. Hence bugs in Fossil are unlikely to corrupt the repository in a way that prevents us from extracting historical versions of files. <h2>Checksum Over All Files In A Check-in</h2> Manifest artifacts that define a check-in have two fields (the R-card and Z-card) that record MD5 hashes of the manifest itself and of all other files in the manifest. Prior to any check-in commit, these checksums are verified to ensure that the check-in agrees exactly with what is on disk. Similarly, the repository checksum is verified after a checkout to make sure that the entire repository was checked out correctly. Note that these added checks use a different hash algorithm (MD5) in order to avoid common-mode failures in the hash algorithm implementation. <h2>Checksums On Structural Artifacts And Deltas</h2> Every [./fileformat.wiki | structural artifact] in a Fossil repository contains a "Z-card" bearing an MD5 checksum over the rest of the artifact. Any mismatch causes the structural artifact to be ignored. The [./delta_format.wiki | file delta format] includes a 32-bit checksum of the target file. Whenever a file is reconstructed from a delta, that checksum is verified to make sure the reconstruction was done correctly. <h2>Reliability Versus Performance</h2> Some version control systems make a big deal out of being "high performance" or the "fastest version control system". Fossil makes no such claims and has no such ambition. Indeed, profiling indicates that Fossil bears a substantial performance cost for doing all of the checksumming and verification outlined above. Fossil takes the philosophy of the <a href="http://en.wikipedia.org/wiki/The_Tortoise_and_the_Hare">tortoise</a>: reliability is more important than raw speed. The developers of Fossil see no merit in getting the wrong answer quickly. Fossil may not be the fastest versioning system, but it is <i>fast enough</i>. Fossil runs quickly enough to stay out of the developer's way. Most operations complete in milliseconds, faster than you can press the "Enter" key. |

As of 2017-07-25 there are three publicly accessible repositories for the Fossil source code: 1. [https://www.fossil-scm.org/] 2. [https://www2.fossil-scm.org/] 3. [https://www3.fossil-scm.org/site.cgi] The canonical repository is (1). Repositories (2) and (3) automatically stay in synchronization with (1) via a <a href="http://en.wikipedia.org/wiki/Cron">cron job</a> that invokes "fossil sync" at regular intervals. Repository (2) also publishes a [./mirrortogithub.md|GitHub mirror of Fossil] as a demonstration. Note that the two secondary repositories are more than just read-only mirrors. All three servers support full read/write capabilities. Changes (such as new tickets or wiki or check-ins) can be implemented on any of the three servers and those changes automatically propagate to the other two servers. Server (1) runs as a CGI script on a <a href="http://www.linode.com/">Linode 8192</a> located in Dallas, TX - on the same virtual machine that hosts <a href="http://www.sqlite.org/">SQLite</a> and over a dozen other smaller projects. This demonstrates that Fossil can run on a low-power host processor. Multiple fossil-based projects can easily be hosted on the same machine, even if that machine is itself one of several dozen virtual machines on single physical box. The CGI script that runs the canonical Fossil self-hosting repository is as follows: <blockquote><pre> #!/usr/bin/fossil repository: /fossil/fossil.fossil </pre></blockquote> Server (3) ran for 10 years as a CGI script on a shared hosting account at <a href="http://www.he.net/">Hurricane Electric</a> in Fremont, CA. This server demonstrated the ability of Fossil to run on an economical shared-host web account with no privileges beyond port 80 HTTP access and CGI. It is not necessary to have a dedicated computer with administrator privileges to run Fossil. As far as we are aware, Fossil is the only full-featured configuration management system that can run in such a restricted environment. The CGI script that ran on the Hurricane Electric server was the same as the CGI script shown above, except that the pathnames are modified to suit the environment: <blockquote><pre> #!/home/hwaci/bin/fossil repository: /home/hwaci/fossil/fossil.fossil </pre></blockquote> In recent years, virtual private servers have become a more flexible and less expensive hosting option compared to shared hosting accounts. So on 2017-07-25, server (3) was moved onto a $5/month "droplet" [https://en.wikipedia.org/wiki/Virtual_private_server|VPS] from [https://www.digitalocean.com|Digital Ocean] located in San Francisco. Server (3) is synchronized with the canonical server (1) by running the following command via cron: <blockquote><pre> /home/hwaci/bin/fossil sync -R /home/hwaci/fossil/fossil.fossil </pre></blockquote> Server (2) is a <a href="http://www.linode.com/">Linode 4096</a> located in Newark, NJ and set up just like the canonical server (1) with the addition of a cron job for synchronization. The same cron job also runs the [/help?cmd=git|fossil git export] command after each sync in order to [./mirrortogithub.md#ex1|mirror all changes to GitHub]. |

This feature allows Fossil to seamlessly integrate into a larger website. We use CGI for the [self-hosting Fossil repository web site](../../selfhost.wiki). To run Fossil as CGI, create a CGI script (here called "repo") in the CGI directory of your web server with content like this: #!/usr/bin/fossil repository: /home/fossil/repo.fossil Adjust the paths appropriately. It may be necessary to set certain permissions on this file or to modify an `.htaccess` file or make other server-specific changes. Consult the documentation for your particular web server. The following permissions are *normally* required, but, again, may be different for a particular configuration: * The Fossil binary (`/usr/bin/fossil` in the example above) must be readable/executable. * *All* directories leading up to the Fossil binary must be readable by the process which executes the CGI. * The CGI script must be executable for the user under which it will run, which often differs from the one running the web server. Consult your site's documentation or the web server’s system administrator. * *All* directories leading to the CGI script must be readable by the web server. * The repository file *and* the directory containing it must be writable by the same account which executes the Fossil binary. (This might differ from the user the web server normally runs under.) The directory holding the repository file(s) needs to be writable so that SQLite can write its journal files. * Fossil must be able to create temporary files in a [directory that varies by host OS](../../env-opts.md#temp). When the CGI process is operating [within a chroot](../../chroot.md), ensure that this directory exists and is readable/writeable by the user who executes the Fossil binary. Once the CGI script is set up correctly, and assuming your server is also set correctly, you should be able to access your repository with a URL like: <b>http://mydomain.org/cgi-bin/repo</b> This is assuming you are running a web server like Apache that uses a “`cgi-bin`†directory for scripts like our “`repo`†example. To serve multiple repositories from a directory using CGI, use the "directory:" tag in the CGI script rather than "repository:". You might also want to add a "notfound:" tag to tell where to redirect if the particular repository requested by the URL is not found: #!/usr/bin/fossil directory: /home/fossil/repos notfound: http://url-to-go-to-if-repo-not-found/ Once deployed, a URL like: <b>http://mydomain.org/cgi-bin/repo/XYZ</b> will serve up the repository `/home/fossil/repos/XYZ.fossil` if it exists. Additional options available to the CGI script are [documented separately](../../cgi.wiki). *[Return to the top-level Fossil server article.](../)* |

To do so, add a line like the following to its configuration file, typically `/etc/inetd.conf`: 80 stream tcp nowait.1000 root /usr/bin/fossil /usr/bin/fossil http /home/fossil/repo.fossil In this example, you are telling `inetd` that when an incoming connection appears on TCP port 80 that it should launch the program `/usr/bin/fossil` with the arguments shown. Obviously you will need to modify the pathnames for your particular setup. The final argument is either the name of the fossil repository to be served or a directory containing multiple repositories. If you use a non-standard TCP port on systems where the port specification must be a symbolic name and cannot be numeric, add the desired name and port to `/etc/services`. For example, if you want your Fossil server running on TCP port 12345 instead of 80, you will need to add: fossil 12345/tcp # fossil server and use the symbolic name “`fossil`†instead of the numeric TCP port number (“12345†in the above example) in `inetd.conf`. Notice that we configured `inetd` to launch Fossil as root. See the top-level section on “[The Fossil Chroot Jail](../../chroot.md)†for the consequences of this and alternatives to it. You can instead configure `inetd` to bind to a higher-numbered TCP port, allowing Fossil to be run as a normal user. In that case, Fossil will not put itself into a chroot jail, because it assumes you have set up file permissions and such on the server appropriate for that user. The `inetd` daemon must be enabled for this to work, and it must be restarted whenever its configuration file changes. This is a more complicated method than the [standalone HTTP server method](./none.md), but it has the advantage of only using system resources when an actual connection is attempted. If no one ever connects to that port, a Fossil server will not (automatically) run. It has the disadvantage of requiring "root" access, which may not be available to you, either due to local IT policy or because of restrictions at your shared Internet hosting service. For further details, see the relevant section in your system's documentation. The FreeBSD Handbook covers `inetd` in [this chapter](https://www.freebsd.org/doc/en/books/handbook/network-inetd.html). *[Return to the top-level Fossil server article.](../)* |

Both of these commands start a Fossil server, usually on TCP port 8080, though a higher numbered port will be used instead if 8080 is already occupied. You can access these using URLs of the form **http://localhost:8080/**, or if _REPOSITORY_ is a directory, URLs of the form **http://localhost:8080/**_repo_**/** where _repo_ is the base name of the repository file without the “`.fossil`†suffix. There are several key differences between “`ui`†and “`server`â€: * “`ui`†always binds the server to the loopback IP address (127.0.0.1) so that it cannot serve to other machines. * Anyone who visits this URL is treated as the all-powerful Setup user, which is why the first difference exists. * “`ui`†launches a local web browser pointed at this URL. You can omit the _REPOSITORY_ argument if you run one of the above commands from within a Fossil checkout directory to serve that repository: $ fossil ui # or... $ fossil server You can abbreviate Fossil sub-commands as long as they are unambiguous. “`server`†can currently be as short as “`ser`â€. You can serve a directory containing multiple `*.fossil` files like so: $ fossil server --port 9000 --repolist /path/to/repo/dir There is an [example script](/file/tools/fslsrv) in the Fossil distribution that wraps `fossil server` to produce more complicated effects. Feel free to take it, study it, and modify it to suit your local needs. See the [online documentation](/help/server) for more information on the options and arguments you can give to these commands. *[Return to the top-level Fossil server article.](../)* |

SCGI) mode, which uses the same [`fossil server`](/help/server) command as for HTTP service. Simply add the `--scgi` command-line option and the stand-alone server will speak the SCGI protocol rather than raw HTTP. This can be used with a web server such as [nginx](http://nginx.org) which does not support [Fossil’s CGI mode](./cgi.md). A basic nginx configuration to support SCGI with Fossil looks like this: location /code/ { include scgi_params; scgi_param SCRIPT_NAME "/code"; scgi_pass localhost:9000; } The `scgi_params` file comes with nginx, and it simply translates nginx internal variables to `scgi_param` directives to create SCGI environment variables for the proxied program; in this case, Fossil. Our explicit `scgi_param` call to define `SCRIPT_NAME` adds one more variable to this set, which is necessary for this configuration to work properly, because our repo isn’t at the root of the URL hierarchy. Without it, when Fossil generates absolute URLs, they’ll be missing the `/code` part at the start, which will typically cause [404 errors][404]. The final directive simply tells nginx to proxy all calls to URLs under `/code` down to an SCGI program on TCP port 9000. We can temporarily set Fossil up as a server on that port like so: $ fossil server /path/to/repo.fossil --scgi --localhost --port 9000 & The `--scgi` option switches Fossil into SCGI mode from its default, which is [stand-alone HTTP server mode](./none.md). All of the other options discussed in that linked document — such as the ability to serve a directory full of Fossil repositories rather than just a single repository — work the same way in SCGI mode. The `--localhost` option is simply good security: we’re using nginx to expose Fossil service to the outside world, so there is no good reason to allow outsiders to contact this Fossil SCGI server directly. Giving an explicit non-default TCP port number via `--port` is a good idea to avoid conflicts with use of Fossil’s default TCP service port, 8080, which may conflict with local uses of `fossil ui` and such. We characterized the SCGI service start command above as “temporary†because running Fossil in the background like that means it won’t start back up on a reboot of the server. A simple solution to that is to add that command to `/etc/rc.local` on systems that have it. However, you might want to consider setting Fossil up as an OS service instead, so that you get the benefits of the platform’s service management framework: * [Linux (systemd)](../debian/service.md) * [Windows service](../windows/service.md) * [macOS (launchd)](../macos/service.md) * [xinetd](../any/xinetd.md) * [inetd](../any/inetd.md) We go into more detail on nginx service setup with Fossil in our [Debian/Ubuntu specific guide](../debian/nginx.md). Then in [a later article](../../tls-nginx.md) that builds upon that, we show how to add TLS encryption to this basic SCGI + nginx setup on Debian type OSes. Similarly, our [OpenBSD specific guide](../openbsd/httpd.md) details how to setup a Fossil server using httpd and FastCGI on OpenBSD. *[Return to the top-level Fossil server article.](../)* [404]: https://en.wikipedia.org/wiki/HTTP_404 |

(Fossil *can* speak HTTPS, but only as a client.) `stunnel` decodes the HTTPS data from the outside world as HTTP before passing it to Fossil, and it encodes the HTTP replies from Fossil as HTTPS before sending them to the remote host that made the request. You can run `stunnel` in one of two modes: socket listener — much like in our [`inetd` doc](./inetd.md) — and as an HTTP reverse proxy. We’ll cover both cases here, separately. ## S<a name="sa"></a>ocket Activation The following `stunnel.conf` configuration configures it to run Fossil in socket listener mode, launching Fossil only when an HTTPS hit comes in, then shutting it back down as soon as the transaction is complete: ```dosini [fossil] accept = 443 TIMEOUTclose = 0 exec = /usr/bin/fossil execargs = /usr/bin/fossil http /home/fossil/ubercool.fossil --https cert = /etc/letsencrypt/live/ubercool-project.org/fullchain.pem key = /etc/letsencrypt/live/ubercool-project.org/privkey.pem ciphers = ECDHE-RSA-AES256-GCM-SHA384:ECDHE-RSA-AES128-GCM-SHA256:ECDHE-RSA-AES256-SHA384:ECDHE-RSA-AES256-SHA:ECDHE-RSA-AES128-SHA256:ECDHE-RSA-AES128-SHA:AES256-GCM-SHA384:AES128-GCM-SHA256:AES256-SHA256:AES128-SHA256:AES128-SHA:DES-CBC3-SHA options = CIPHER_SERVER_PREFERENCE ``` This configuration shows the TLS certificate generated by the [Let’s Encrypt](https://letsencrypt.org) [Certbot](https://certbot.eff.org) in [certonly mode](https://certbot.eff.org/lets-encrypt/debianbuster-other). There are other ways to get TLS certificates, but this is a popular and free option. You will need to adjust the site names and paths in this example. Where this file goes varies by OS type, so check the man pages on your system to find out where it should be locally. See the `stunnel` documentation for further details about this configuration file. It is important that the [`fossil http`](/help/http) command in that configuration include the `--https` option to let Fossil know to use “`https://`†instead of “`http://`†in generated hyperlinks. ## <a name="proxy"></a>Reverse Proxy You can instead have Fossil running in the background in [standalone HTTP server mode](./none.md), bound to a high random TCP port number on localhost via the `--localhost` and `--port` flags, then configure `stunnel` to reverse proxy public HTTPS connections down to it via HTTP. The configuration is the same as the above except that you drop the `exec` and `execargs` directives and add this instead: ```dosini connect = 9000 ``` That tells `stunnel` to connect to an already-running process listening on the given TCP port number. There are a few advantages to this mode: 1. At the cost of some server memory and a tiny bit of idle CPU time, Fossil remains running so that hits can be served a smidge faster than in socket listener mode, where the Fossil binary has to be loaded and re-initialized on each HTTPS hit. 2. The socket listener mode doesn’t work on all platforms that `stunnel` runs on, particularly [on Windows](../windows/stunnel.md). *[Return to the top-level Fossil server article.](../)* |

The typical configuration file is either `/etc/xinetd.conf` or a subfile in the `/etc/xinetd.d` directory. You need a configuration something like this for Fossil: service http { port = 80 socket_type = stream wait = no user = root server = /usr/bin/fossil server_args = http /home/fossil/repos/ } This example configures Fossil to serve multiple repositories under the `/home/fossil/repos/` directory.

Here, we add more detailed information on nginx itself, plus details about running it on Debian type OSes. We focus on Debian 10 (Buster) and Ubuntu 18.04 here, which are common Tier 1 OS offerings for [virtual private servers][vps]. This material may not work for older OSes. It is known in particular to not work as given for Debian 9 and older! If you want to add TLS to this configuration, that is covered [in a separate document][tls] which was written with the assumption that you’ve read this first. [scgii]: ../any/scgi.md [tls]: ../../tls-nginx.md [vps]: https://en.wikipedia.org/wiki/Virtual_private_server ## <a name="benefits"></a>Benefits This scheme is considerably more complicated than the [standalone HTTP server](../any/none.md) and [CGI options](../any/cgi.md). Even with the benefit of this guide and pre-built binary packages, it requires quite a bit of work to set it up. Why should you put up with this complexity? Because it gives many benefits that are difficult or impossible to get with the less complicated options: * **Power** — nginx is one of the most powerful web servers in the world. The chance that you will run into a web serving wall that you can’t scale with nginx is very low. To give you some idea of the sort of thing you can readily accomplish with nginx, your author runs a single public web server that provides transparent name-based virtual hosting for four separate domains: * One is entirely static, not involving any dynamic content or Fossil integration at all. * Another is served almost entirely by Fossil, with a few select static content exceptions punched past Fossil, which are handled entirely via nginx. * The other two domains are aliases for one another — e.g. `example.com` and `example.net` — with most of the content being static. This pair of domains has three different Fossil repo proxies attached to various sections of the URI hierarchy. By using nginx, I was able to do all of the above with minimal repetition between the site configurations. * **Integration** — Because nginx is so popular, it integrates with many different technologies, and many other systems integrate with it in turn. This makes it great middleware, sitting between the outer web world and interior site services like Fossil. It allows Fossil to participate seamlessly as part of a larger web stack. * **Availability** — nginx is already in most operating system binary package repositories, so you don’t need to go out of your way to get it. ## <a name="modes"></a>Fossil Service Modes Fossil provides four major ways to access a repository it’s serving remotely, three of which are straightforward to use with nginx: * **HTTP** — Fossil has a built-in HTTP server: [`fossil server`](../any/none.md). While this method is efficient and it’s possible to use nginx to proxy access to another HTTP server, we don’t see any particularly good reason to make nginx reinterpret Fossil’s own implementation of HTTP when we have a better option. (But see [below](#http).) * **CGI** — This method is simple but inefficient, because it launches a separate Fossil instance on every HTTP hit. Since Fossil is a relatively small self-contained program, and it’s designed to start up quickly, this method can work well in a surprisingly large number of cases. Nevertheless, we will avoid this option in this document because we’re already buying into a certain amount of complexity here in order to gain power. There’s no sense in throwing away any of that hard-won performance on CGI overhead. * **SCGI** — The [SCGI protocol][scgip] provides the simplicity of CGI without its performance problems. * **SSH** — This method exists primarily to avoid the need for HTTPS, but we *want* HTTPS. (We’ll get to that in [another document][tls].) There is probably a way to get nginx to proxy Fossil to HTTPS via SSH, but it would be pointlessly complicated. SCGI it is, then. [scgip]: https://en.wikipedia.org/wiki/Simple_Common_Gateway_Interface ## <a name="deps"></a>Installing the Dependencies The first step is to install some non-default packages we’ll need. SSH into your server, then say: $ sudo apt install fossil nginx ## <a name="scgi"></a>Running Fossil in SCGI Mode For the following nginx configuration to work, it needs to contact a Fossil instance speaking the SCGI protocol. There are [many ways](../) to set that up. For Debian type systems, we recommend following [our systemd system service guide](service.md). There are other ways to arrange for Fossil to run as a service backing nginx, but however you do it, you need to match up the TCP port numbers between it and those in the nginx configuration below. ## <a name="config"></a>Configuration On Debian and Ubuntu systems the primary user-level configuration file for nginx is `/etc/nginx/sites-enabled/default`. I recommend that this file contain only a list of include statements, one for each site that server hosts: include local/example.com include local/foo.net Those files then each define one domain’s configuration. Here, `/etc/nginx/local/example.com` contains the configuration for `*.example.com` and its alias `*.example.net`; and `local/foo.net` contains the configuration for `*.foo.net`. The configuration for our `example.com` web site, stored in `/etc/nginx/sites-enabled/local/example.com` is: server { server_name .example.com .example.net ""; include local/generic; access_log /var/log/nginx/example.com-https-access.log; error_log /var/log/nginx/example.com-https-error.log; # Bypass Fossil for the static documentation generated from # our source code by Doxygen, so it merges into the embedded # doc URL hierarchy at Fossil’s $ROOT/doc without requiring that # these generated files actually be stored in the repo. This # also lets us set aggressive caching on these docs, since # they rarely change. location /code/doc/html { root /var/www/example.com/code/doc/html; location ~* \.(html|ico|css|js|gif|jpg|png)$ { expires 7d; add_header Vary Accept-Encoding; access_log off; } } # Redirect everything else to the Fossil instance location /code { include scgi_params; scgi_param SCRIPT_NAME "/code"; scgi_pass 127.0.0.1:12345; } } As you can see, this is a pure extension of [the basic nginx service configuration for SCGI][scgii], showing off a few ideas you might want to try on your own site, such as static asset proxying. The `local/generic` file referenced above helps us reduce unnecessary repetition among the multiple sites this configuration hosts: root /var/www/$host; listen 80; listen [::]:80; charset utf-8; There are some configuration directives that nginx refuses to substitute variables into, citing performance considerations, so there is a limit to how much repetition you can squeeze out this way. One such example is the `access_log` and `error_log` directives, which follow an obvious pattern from one host to the next. Sadly, you must tolerate some repetition across `server { }` blocks when setting up multiple domains on a single server. The configuration for `foo.net` is similar. See [the nginx docs](http://nginx.org/en/docs/) for more ideas. ## <a name="http"></a>Proxying HTTP Anyway [Above](#modes), we argued that proxying SCGI is a better option than making nginx reinterpret Fossil’s own implementation of HTTP. If you want Fossil to speak HTTP, just [set Fossil up as a standalone server](../any/none.md). And if you want nginx to [provide TLS encryption for Fossil][tls], proxying HTTP instead of SCGI provides no benefit. However, it is still worth showing the proper method of proxying Fossil’s HTTP server through nginx if only to make reading nginx documentation on other sites easier: location /code { rewrite ^/code(/.*) $1 break; proxy_pass http://127.0.0.1:12345; } The most common thing people get wrong when hand-rolling a configuration like this is to get the slashes wrong. Fossil is senstitive to this. For instance, Fossil will not collapse double slashes down to a single slash, as some other HTTP servers will. *[Return to the top-level Fossil server article.](../)* |

There are multiple ways to get a service to launch under `systemd`. We’re going to show two methods which correspond approximately to two of our generic Fossil server setup methods, the [`inetd`](../any/inetd.md) and [standalone HTTP server](../any/none.md) methods. [sdhome]: https://www.freedesktop.org/wiki/Software/systemd/ [wpa]: https://en.wikipedia.org/wiki/Systemd#Adoption ## User Service A fun thing you can easily do with `systemd` that you can’t directly do with older technologies like `inetd` and `xinetd` is to set a server up as a “user†service. You can’t listen on TCP port 80 with this method due to security restrictions on TCP ports in every OS where `systemd` runs, but you can create a listener socket on a high-numbered (≥ 1024) TCP port, suitable for sharing a Fossil repo to a workgroup on a private LAN. To do this, write the following in `~/.local/share/systemd/user/fossil.service`: ```dosini [Unit] Description=Fossil user server After=network.target [Service] WorkingDirectory=/home/fossil/museum ExecStart=/home/fossil/bin/fossil server --port 9000 repo.fossil Restart=always RestartSec=3 [Install] WantedBy=sockets.target WantedBy=multi-user.target ``` Unlike with `inetd` and `xinetd`, we don’t need to tell `systemd` which user and group to run this service as, because we’ve installed it under the account we’re logged into, which `systemd` will use as the service’s owner. We’ve told `systemd` that we want automatic service restarts with back-off logic, making this much more robust than the by-hand launches of `fossil` in the platform-independent Fossil server instructions. The service will stay up until we explicitly tell it to shut down. A simple and useful modification to the above scheme is to add the `--scgi` and `--localhost` flags to the `ExecStart` line to replace the use of `fslsrv` in [the generic SCGI instructions](../any/scgi.md), giving a much more robust configuration. Because we’ve set this up as a user service, the commands you give to manipulate the service vary somewhat from the sort you’re more likely to find online: $ systemctl --user daemon-reload $ systemctl --user enable fossil $ systemctl --user start fossil $ systemctl --user status -l fossil $ systemctl --user stop fossil That is, we don’t need to talk to `systemd` with `sudo` privileges, but we do need to tell it to look at the user configuration rather than the system-level configuration. This scheme isolates the permissions needed by the Fossil server, which reduces the amount of damage it can do if there is ever a remotely-triggerable security flaw found in Fossil. On some `systemd` based OSes, user services only run while that user is logged in interactively. This is common on systems aiming to provide desktop environments, where this is the behavior you often want. To allow background services to continue to run after logout, say: $ sudo loginctl enable-linger $USER You can paste the command just like that into your terminal, since `$USER` will expand to your login name. ### System Service Alternative Another workaround for the problem with user services above is to install the service as a system service instead. This is a better path when you are proxying Fossil with a system-level service, such as [nginx](./nginx.md). There are just a small set of changes required: 1. Install the unit file to one of the persistent system-level unit file directories. Typically, these are: /etc/systemd/system /lib/systemd/system 2. Add `User` and `Group` directives to the `[Service]` section so Fossil runs as a normal user, preferrably one with access only to the Fossil repo files, rather than running as `root`. ## Socket Activation Another useful method to serve a Fossil repo via `systemd` is via a socket listener, which `systemd` calls “[socket activation][sa].†It’s more complicated, but it has some nice properties. It is the feature that allows `systemd` to replace `inetd`, `xinetd`, Upstart, and several other competing technologies. We first need to define the privileged socket listener by writing `/etc/systemd/system/fossil.socket`: ```dosini [Unit] Description=Fossil socket [Socket] Accept=yes ListenStream=80 NoDelay=true [Install] WantedBy=sockets.target ``` Note the change of configuration directory from the `~/.local` directory to the system level. We need to start this socket listener at the root level because of the low-numbered TCP port restriction we brought up above. This configuration says more or less the same thing as the socket part of an `inted` entry [exemplified elsewhere in this documentation](../any/inetd.md). Next, create the service definition file in that same directory as `fossil@.service`: ```dosini [Unit] Description=Fossil socket server After=network.target [Service] WorkingDirectory=/home/fossil/museum ExecStart=/home/fossil/bin/fossil http repo.fossil StandardInput=socket [Install] WantedBy=sockets.target WantedBy=multi-user.target ``` We’ll explain the “`@`†in the file name below. Notice that we haven’t told `systemd` which user and group to run Fossil under. Since this is a system-level service definition, that means it will run as root, which then causes Fossil to [automatically drop into a `chroot(2)` jail](../../chroot.md) rooted at the `WorkingDirectory` we’ve configured above, shortly each `fossil http` call starts. The `Restart*` directives we had in the user service configuration above are unnecessary for this method, since Fossil isn’t supposed to remain running under it. Each HTTP hit starts one Fossil instance, which handles that single client’s request and then immediately shuts down. Next, you need to tell `systemd` to reload its system-level configuration files and enable the listening socket: $ sudo systemctl daemon-reload $ sudo systemctl enable fossil.socket And now you can manipulate the socket listener: $ sudo systemctl start fossil.socket $ sudo systemctl status -l fossil.socket $ sudo systemctl stop fossil.socket Notice that we’re working with the *socket*, not the *service*. The fact that we’ve given them the same base name and marked the service as an instantiated service with the “`@`†notation allows `systemd` to automatically start an instance of the service each time a hit comes in on the socket that `systemd` is monitoring on Fossil’s behalf. To see this service instantiation at work, visit a long-running Fossil page (e.g. `/tarball`) and then give a command like this: $ sudo systemctl --full | grep fossil This will show information about the `fossil` socket and service instances, which should show your `/tarball` hit handler, if it’s still running: fossil@20-127.0.0.1:80-127.0.0.1:38304.service You can feed that service instance description to a `systemctl kill` command to stop that single instance without restarting the whole `fossil` service, for example. In all of this, realize that we’re able to manipulate a single socket listener or single service instance at a time, rather than reload the whole externally-facing network configuration as with the far more primitive `inetd` service.

The 10-digit random password generated for that user is fairly strong against remote attack, even without explicit password guess rate limiting, but because that user has so much power, you may want to give it a much stronger password under Admin → Users.</a></li> <li><p>Run the Admin → Security-Audit tool to verify that other security-related permissions and settings are as you want them. Consider clicking the “Take it private†link on that page to lock down the security on that site to a level appropriate to a private repository, even if you will eventually want some public service. It's better to start from a secure position and open up service feature-by-feature as necessary than it is to start from a fully open position and lock down features one by one to achieve a secure stance.</p></li> </ol> <p>With the repository secured, it is safe to upload a copy of the repository file to your server and proceed with server setup, below. Further configuration steps can wait until <a href="#postsetup">after the server is running</a>.</p> <h2 id="methods">Activation Methods</h2> <p>There are basically four ways to run a Fossil server:</p> <ol> <li><a id="cgi" href="any/cgi.md">CGI</a> <li>Socket listener <li><a id="standalone" href="any/none.md">Stand-alone HTTP server</a> <li><a id="scgi" href="any/scgi.md">SCGI</a> </ol> <p>All of these methods can serve either a single repository or a directory hierarchy containing mulitiple repositories.</p> <p>You are not restricted to a single server setup. The same Fossil repository can be served using two or more of the above techniques at the same time. These methods use clean, well-defined, standard interfaces (CGI, SCGI, and HTTP) which allow you to easily migrate from one method to another in response to changes in hosting providers or administrator preferences.</p> <h3>CGI</h3> <p>Most ordinary web servers can <a href="any/cgi.md">run Fossil as a CGI script</a>. This method is known to work with Apache, <tt>lighttpd</tt>, and <a href="any/althttpd.md"><tt>althttpd</tt></a>. The Fossil server administrator places a <a href="$ROOT/help?cmd=cgi">short CGI script</a> in the web server's document hierarchy and when a client requests the URL that corresponds to that script, Fossil runs and generates the response.</p> <p>CGI is a good choice for merging Fossil into an existing web site, particularly on hosts that have CGI set up and working. The Fossil <a href="../selfhost.wiki">self-hosting repositories</a> are implemented with CGI underneath <tt>althttpd</tt>.</p> <h3>Socket Listener</h3> <p>Socket listener daemons such as <a id="inetd" href="any/inetd.md"><tt>inetd</tt></a>, <a id="xinetd" href="any/xinetd.md"><tt>xinetd</tt></a>, <a id="stunnel" href="any/stunnel.md"><tt>stunnel</tt></a>, <a href="macos/service.md"><tt>launchd</tt></a>, and <a href="debian/service.md"><tt>systemd</tt></a> can be configured to invoke the the <a href="$ROOT/help?cmd=http"><tt>fossil http</tt></a> command to handle each incoming HTTP request. The "<tt>fossil http</tt>" command reads the HTTP request off of standard input, computes an appropriate reply, and writes the reply on standard output. There is a separate invocation of the "<tt>fossil http</tt>" command for each HTTP request. The socket listener daemon takes care of relaying content to and from the client, and (in the case of <a href="any/stunnel.md">stunnel</a>) handling TLS decryption and encryption. <h3>Stand-alone HTTP Server</h3> <p>This is the <a href="any/none.md">easiest method</a>. A stand-alone server uses the <a href="$ROOT/help?cmd=server"><tt>fossil server</tt></a> command to run a process that listens for incoming HTTP requests on a socket and then dispatches a copy of itself to deal with each incoming request. You can expose Fossil directly to the clients in this way or you can interpose a <a href="https://en.wikipedia.org/wiki/Reverse_proxy">reverse proxy</a> layer between the clients and Fossil.</p> <h3>SCGI</h3> <p>The Fossil standalone server can also handle <a href="any/scgi.md">SCGI</a>. When the <a href="$ROOT/help?cmd=server"><tt>fossil server</tt></a> command is run with the extra <tt>--scgi</tt> option, it listens for incoming SCGI requests rather than HTTP requests. This allows Fossil to respond to requests from web servers <a href="debian/nginx.md">such as nginx</a> that don't support CGI. SCGI is a simpler protocol to proxy than HTTP, since the HTTP doesn't have to be re-interpreted in terms of the proxy's existing HTTP implementation, but it's more complex to set up because you also have to set up an SCGI-to-HTTP proxy for it. It is worth taking on this difficulty only when you need to integrate Fossil into an existing web site already being served by an SCGI-capable web server.</p> <h2 id="matrix">Activation Tutorials</h2> <p>We've broken the configuration for each method out into a series of sub-articles.

If you want a Fossil server to launch in the background on a Mac, it’s the way Apple wants you to do it. `launchd` is to macOS as `systemd` is to most modern Linux desktop systems. (Indeed, `systemd` arguably reinvented the perfectly good, pre-existing `launchd` wheel.) Unlike in [our `systemd` article](../debian/service.md), we’re not going to show the per-user method here, because those so-called [LaunchAgents][la] only start when a user is logged into the GUI, and they stop when that user logs out. This does not strike us as proper “server†behavior, so we’ll stick to system-level LaunchDaemons instead. However, we will still give two different configurations, just as in the `systemd` article: one for a standalone HTTP server, and one using socket activation. For more information on `launchd`, the single best resource we’ve found is [](launchd.info). The next best is: $ man launchd.plist [la]: http://www.grivet-tools.com/blog/2014/launchdaemons-vs-launchagents/ [ldhome]: https://developer.apple.com/library/archive/documentation/MacOSX/Conceptual/BPSystemStartup/Chapters/CreatingLaunchdJobs.html [wpa]: https://en.wikipedia.org/wiki/Launchd ## Standalone HTTP Server To configure `launchd` to start Fossil as a standalone HTTP server, write the following as `com.example.dev.FossilHTTP.plist`: ```xml <?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd"> <plist version="1.0"> <dict> <key>Label</key> <string>com.example.dev.FossilHTTP</string> <key>ProgramArguments</key> <array> <string>/usr/local/bin/fossil</string> <string>server</string> <string>--port</string> <string>9000</string> <string>repo.fossil</string> </array> <key>WorkingDirectory</key> <string>/Users/you/museum</string> <key>KeepAlive</key> <true/> <key>RunAtLoad</key> <true/> <key>StandardErrorPath</key> <string>/tmp/fossil-error.log</string> <key>StandardOutPath</key> <string>/tmp/fossil-info.log</string> <key>UserName</key> <string>you</string> <key>GroupName</key> <string>staff</string> <key>InitGroups</key> <true/> </dict> </plist> ``` In this example, we’re assuming your development organization uses the domain name “`dev.example.org`â€, that your short macOS login name is “`you`â€, and that you store your Fossils in “`~/museum`â€. Adjust these elements of the plist file to suit your local situation. You might be wondering about the use of `UserName`: isn’t Fossil supposed to drop privileges and enter [a `chroot(2)` jail](../../chroot.md) when it’s started as root like this? Why do we need to give it a user name? Won’t Fossil use the owner of the repository file to set that? All I can tell you is that in testing here, if you leave the user and group configuration at the tail end of that plist file out, Fossil will remain running as root! Install that file and set it to start with: $ sudo install -o root -g wheel -m 644 com.example.dev.FossilHTTP.plist \ /Library/LaunchDaemons/ $ sudo launchctl load -w /Library/LaunchDaemons/com.example.dev.FossilHTTP.plist Because we set the `RunAtLoad` key, this will also launch the daemon. Stop the daemon with: $ sudo launchctl unload -w /Library/LaunchDaemons/com.example.dev.FossilHTTP.plist ## Socket Listener Another useful method to serve a Fossil repo via `launchd` is by setting up a socket listener: ```xml <?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd"> <plist version="1.0"> <dict> <key>Label</key> <string>com.example.dev.FossilSocket</string> <key>ProgramArguments</key> <array> <string>/usr/local/bin/fossil</string> <string>http</string> <string>repo.fossil</string> </array> <key>Sockets</key> <dict> <key>Listeners</key> <dict> <key>SockServiceName</key> <string>9001</string> <key>SockType</key> <string>stream</string> <key>SockProtocol</key> <string>TCP</string> <key>SockFamily</key> <string>IPv4</string> </dict> </dict> <key>inetdCompatibility</key> <dict> <key>Wait</key> <false/> </dict> <key>WorkingDirectory</key> <string>/Users/you/museum</string> <key>UserName</key> <string>you</string> <key>GroupName</key> <string>staff</string> <key>InitGroups</key> <true/> </dict> </plist> ``` Save it as “`com.example.dev.FossilSocket.plist`†and install and load it into `launchd` as above. This version differs in several key ways: 1. We’re calling Fossil as `fossil http` rather than `fossil server` to make it serve a single request and then shut down immediately. 2. We’ve told `launchd` to listen on our TCP port number instead of passing it to `fossil`. 3. We’re running the daemon in `inetd` compatibility mode of `launchd` with “wait†mode off, which tells it to attach the connected socket to the `fossil` process’s stdio handles. 4. We’ve removed the `Standard*Path` keys because they interfere with our use of stdio handles for HTTP I/O. You might therefore want to start with the first method and then switch over to this one only once you’ve got the daemon launching debugged, since once you tie up stdio this way, you won’t be able to get logging information from Fossil via that path. (Fossil does have some internal logging mechanisms, but you can’t get at them until Fossil is launching!) 5. We’ve removed the `KeepAlive` and `RunAtLoad` keys because those options aren’t appropriate to this type of service. 6. Because we’re running it via a socket listener instead of as a standalone HTTP server, the Fossil service only takes system resources when it’s actually handling an HTTP hit. If your Fossil server is mostly idle, this method will be a bit more efficient than the first option. *[Return to the top-level Fossil server article.](../)* |

It's minimal and lightweight but secure and capable, and provides a clean interface for setting up a Fossil server using FastCGI. This article will detail the steps required to setup a TLS-enabled `httpd` configuration that serves multiple Fossil repositories out of a single directory within a chroot, and allow `ssh` access to create new repositories remotely. **NOTE:** The following instructions assume an OpenBSD 6.7 installation. [httpd]: https://www.openbsd.org/papers/httpd-asiabsdcon2015.pdf ## <a name="fslinstall"></a>Install Fossil Use the OpenBSD package manager `pkg_add` to install Fossil, making sure to select the statically linked binary. ```console $ doas pkg_add fossil quirks-3.325 signed on 2020-06-12T06:24:53Z Ambiguous: choose package for fossil 0: <None> 1: fossil-2.10v0 2: fossil-2.10v0-static Your choice: 2 fossil-2.10v0-static: ok ``` This installs Fossil into the chroot. To facilitate local use, create a symbolic link of the fossil executable into `/usr/local/bin`. ```console $ doas ln -s /var/www/bin/fossil /usr/local/bin/fossil ``` As a privileged user, create the file `/var/www/cgi-bin/scm` with the following contents to make the CGI script that `httpd` will execute in response to `fsl.domain.tld` requests; all paths are relative to the `/var/www` chroot. ```sh #!/bin/fossil directory: /htdocs/fsl.domain.tld notfound: https://domain.tld repolist errorlog: /logs/fossil.log ``` The `directory` directive instructs Fossil to serve all repositories found in `/var/www/htdocs/fsl.domain.tld`, while `errorlog` sets logging to be saved to `/var/www/logs/fossil.log`; create the repository directory and log file—making the latter owned by the `www` user, and the script executable. ```console $ doas mkdir /var/www/htdocs/fsl.domain.tld $ doas touch /var/www/logs/fossil.log $ doas chown www /var/www/logs/fossil.log $ doas chmod 755 /var/www/cgi-bin/scm ``` ## <a name="chroot"></a>Setup chroot Fossil needs both `/dev/random` and `/dev/null`, which aren't accessible from within the chroot, so need to be constructed; `/var`, however, is mounted with the `nodev` option. Rather than removing this default setting, create a small memory filesystem with [`mount_mfs(8)`][mfs] upon which `/var/www/dev` will be mounted so that the `random` and `null` device files can be created. ```console $ doas mkdir /var/www/dev $ doas mount_mfs -s 1M /dev/sd0b /var/www/dev $ doas cd /var/www/dev $ doas /dev/MAKEDEV urandom $ doas mknod -m 666 null c 2 2 $ ls -l total 0 crw-rw-rw- 1 root daemon 2, 2 Jun 20 08:56 null lrwxr-xr-x 1 root daemon 7 Jun 18 06:30 random@ -> urandom crw-r--r-- 1 root wheel 45, 0 Jun 18 06:30 urandom ``` [mfs]: https://man.openbsd.org/mount_mfs.8 To make the mountable memory filesystem permanent, open `/etc/fstab` as a privileged user and add the following line to automate creation of the filesystem at startup: ```console swap /var/www/dev mfs rw,-s=1048576 0 0 ``` Then add the following to [`/etc/rc.local(8)`][rc.local] to automate creation of the `random` and `null` device files. ``` echo -n "[!] create device nodes: /var/www/dev/{urandom,null}" cwd=$(pwd) cd /var/www/dev /dev/MAKEDEV urandom mknod -m 666 null c 2 2 cd $cwd echo "." ``` [rc.local]: https://man.openbsd.org/rc.conf.local.8 The same user that executes the fossil binary must have writable access to the repository directory that resides within the chroot; on OpenBSD this is `www`. In addition, grant repository directory ownership to the user who will push to, pull from, and create repositories. ```console $ doas chown -R user:www /var/www/htdocs/fsl.domain.tld $ doas chmod 775 /var/www/htdocs/fsl.domain.tld ``` ## <a name="httpdconfig"></a>Configure httpd On OpenBSD, [httpd.conf(5)][httpd] is the configuration file for `httpd`. To setup the server to serve all Fossil repositores within the directory specified in the CGI script, and automatically redirect standard HTTP requests to HTTPS—apart from [Let's Encrypt][LE] challenges issued in response to [acme-client(1)][acme] certificate requests—create `/etc/httpd.conf` as a privileged user with the following contents. [LE]: https://letsencrypt.org [acme]: https://man.openbsd.org/acme-client.1 [httpd.conf(5)]: https://man.openbsd.org/httpd.conf.5 ```apache server "fsl.domain.tld" { listen on * port http root "/htdocs/fsl.domain.tld" location "/.well-known/acme-challenge/*" { root "/acme" request strip 2 } location * { block return 301 "https://$HTTP_HOST$REQUEST_URI" } location "/*" { fastcgi { param SCRIPT_FILENAME "/cgi-bin/scm" } } } server "fsl.domain.tld" { listen on * tls port https root "/htdocs/fsl.domain.tld" tls { certificate "/etc/ssl/domain.tld.fullchain.pem" key "/etc/ssl/private/domain.tld.key" } hsts { max-age 15768000 preload subdomains } connection max request body 104857600 location "/*" { fastcgi { param SCRIPT_FILENAME "/cgi-bin/scm" } } location "/.well-known/acme-challenge/*" { root "/acme" request strip 2 } } ``` **NOTE:** If not already in possession of a HTTPS certificate, comment out the `https` server block and proceed to securing a free [Let's Encrypt Certificate](#letsencrypt); otherwise skip to [Start `httpd`](#starthttpd). ## <a name="letsencrypt"></a>Let's Encrypt Certificate In order for `httpd` to serve HTTPS, secure a free certificate from Let's Encrypt using `acme-client`. Before issuing the request, however, ensure you have a zone record for the subdomain with your registrar or nameserver. Then open `/etc/acme-client.conf` as a privileged user to configure the request. ```dosini authority letsencrypt { api url "https://acme-v02.api.letsencrypt.org/directory" account key "/etc/acme/letsencrypt-privkey.pem" } authority letsencrypt-staging { api url "https://acme-staging.api.letsencrypt.org/directory" account key "/etc/acme/letsencrypt-staging-privkey.pem" } domain domain.tld { alternative names { www.domain.tld fsl.domain.tld } domain key "/etc/ssl/private/domain.tld.key" domain certificate "/etc/ssl/domain.tld.crt" domain full chain certificate "/etc/ssl/domain.tld.fullchain.pem" sign with letsencrypt } ``` Start `httpd` with the new configuration file, and issue the certificate request. ```console $ doas rcctl start httpd $ doas acme-client -vv domain.tld acme-client: /etc/acme/letsencrypt-privkey.pem: account key exists (not creating) acme-client: /etc/acme/letsencrypt-privkey.pem: loaded RSA account key acme-client: /etc/ssl/private/domain.tld.key: generated RSA domain key acme-client: https://acme-v01.api.letsencrypt.org/directory: directories acme-client: acme-v01.api.letsencrypt.org: DNS: 172.65.32.248 ...

DNosz(???n{L}???D???4[?B] (1174 bytes) acme-client: /etc/ssl/domain.tld.crt: created acme-client: /etc/ssl/domain.tld.fullchain.pem: created ``` A successful result will output the public certificate, full chain of trust, and private key into the `/etc/ssl` directory as specified in `acme-client.conf`. ```console $ doas ls -lR /etc/ssl -r--r--r-- 1 root wheel 2.3K Mar 2 01:31:03 2018 domain.tld.crt -r--r--r-- 1 root wheel 3.9K Mar 2 01:31:03 2018 domain.tld.fullchain.pem /etc/ssl/private: -r-------- 1 root wheel 3.2K Mar 2 01:31:03 2018 domain.tld.key ``` Make sure to reopen `/etc/httpd.conf` to uncomment the second server block responsible for serving HTTPS requests before proceeding. ## <a name="starthttpd"></a>Start `httpd` With `httpd` configured to serve Fossil repositories out of `/var/www/htdocs/fsl.domain.tld`, and the certificates and key in place, enable and start `slowcgi`—OpenBSD's FastCGI wrapper server that will execute the above Fossil CGI script—before checking that the syntax of the `httpd.conf` configuration file is correct, and (re)starting the server (if still running from requesting a Let's Encrypt certificate). ```console $ doas rcctl enable slowcgi $ doas rcctl start slowcgi slowcgi(ok) $ doas httpd -vnf /etc/httpd.conf configuration OK $ doas rcctl start httpd httpd(ok) ``` ## <a name="clientconfig"></a>Configure Client To facilitate creating new repositories and pushing them to the server, add the following function to your `~/.cshrc` or `~/.zprofile` or the config file for whichever shell you are using on your development box. ```sh finit() { fossil init $1.fossil && \ chmod 664 $1.fossil && \ fossil open $1.fossil && \ fossil user password $USER $PASSWD && \ fossil remote-url https://$USER:$PASSWD@fsl.domain.tld/$1 && \ rsync --perms $1.fossil $USER@fsl.domain.tld:/var/www/htdocs/fsl.domain.tld/ >/dev/null && \ chmod 644 $1.fossil && \ fossil ui } ``` This enables a new repository to be made with `finit repo`, which will create the fossil repository file `repo.fossil` in the current working directory; by default, the repository user is set to the environment variable `$USER`. It then opens the repository and sets the user password to the `$PASSWD` environment variable (which you can either set with `export PASSWD 'password'` on the command line or add to a *secured* shell environment file), and the `remote-url` to `https://fsl.domain.tld/repo` with the credentials of `$USER` who is authenticated with `$PASSWD`. Finally, it `rsync`'s the file to the server before opening the local repository in your browser where you can adjust settings such as anonymous user access, and set pertinent repository details. Thereafter, you can add files with `fossil add`, and commit with `fossil ci -m 'commit message'` where Fossil, by default, will push to the `remote-url`. It's suggested you read the [Fossil documentation][documentation]; with a sane and consistent development model, the system is much more efficient and cohesive than `git`—so the learning curve is not steep at all.

Data sharing and synchronization can be entirely peer-to-peer. Fossil uses [https://en.wikipedia.org/wiki/Conflict-free_replicated_data_type|conflict-free replicated data types] to ensure that (in the limit) all participating peers see the same content. <h2>But, A Server Can Be Useful</h2> Fossil does not require a server, but a server can be very useful. Here are a few reasons to set up a Fossil server for your project: 1. <b>A server works as a complete project website.</b><p> Fossil does more than just version control. It also supports [../tickets.wiki|trouble-tickets], [../wikitheory.wiki|wiki], and a [../forum.wiki|forum]. The [../embeddeddoc.wiki|embedded documentation] feature provides a great mechanism for providing project documentation. The [../unvers.wiki|unversioned files] feature is a convenient way to host builds and downloads on the project website. 2. <b>A server gives developers a common point of rendezvous for syncing their work.</b><p> It is possible for developers to synchronize peer-to-peer but that requires the developers coordinate the sync, which in turn requires that the developers both want to sync at the same moment. A server aleviates this time dependency by allowing each developer to sync whenever it is convenient (for example, automatically syncing after each commit and before each update). Developers all stay in sync with each other, without having to interrupt each other constantly to set up a peer-to-peer sync. 3. <b>A server provides project leaders with up-to-date status.</b><p> Project coordinators and BDFLs can click on a link or two at the central Fossil server for a project, and quickly tell what is going on. They can do this from anywhere, even from their phones, without needing to actually sync to the device they are using. 4. <b>A server provides automatic off-site backups.</b><p> A Fossil server is an automatic remote backup for all the work going into a project. You can even set up multiple servers, at multiple sites, with automatic synchronization between them, for added redundancy. Such a set up means that no work is lost due to a single machine failure. |

We recommend that you use the simpler [reverse proxying method](./iis.md) instead unless there is some compelling reason why that method cannot work for you, such as its dependence on non-stock IIS extensions. (Keep in mind that both extensions it requires are by Microsoft, not third parties!) Once you’ve got this scheme working, it gives the same benefits as those listed at the top of the linked-to document. There is a small benefit you get from using CGI over reverse proxying on other OSes, which is that the Fossil program only runs briefly in order to serve each HTTP hit. Once the request is done, that Fossil instance shuts back down, releasing all of its resources. You don’t need to keep a background Fossil HTTP server running full-time to provide CGI-based Fossil service. You lose a lot of that benefit on Windows: 1. It only matters to start with on servers that are highly RAM constrained. (Roughly ≤ 128 MiB.) Our configuration steps below assume you’re using the Windows and IIS GUIs, which have RAM requirements well in excess of this, making Fossil’s resource requirements a drop in the bucket next to them. On the [Azure B1s][b1s] virtual machine I used to prepare these instructions, the Windows Server Manager GUI kept filling the VM’s 1 GiB of RAM during feature installation and crashing. I had to upgrade the VM’s RAM to 2 GiB just to get useful work done! 2. Process creation on Windows is [much more expensive][cp] than on the other OSes Fossil runs on, so the benefits of firing up a Fossil executable to process each HTTP request are partially swamped by the overhead of doing so. Therefore, unless you’re willing to replace all of the GUI configuration steps below with command line equivalents, or shut the GUI down entirely after configuring IIS, CGI is a much less compelling option on Windows. **WARNING:** The following tutorial appears to fail with the current (2019-08-17) version of Fossil, [apparently][fbug] due to an inability of Fossil to detect that it’s being run in CGI mode. [b1s]: https://azure.microsoft.com/en-us/blog/introducing-b-series-our-new-burstable-vm-size/ [cp]: https://stackoverflow.com/a/48244/142454 [fbug]: https://fossil-scm.org/forum/forumpost/de18dc32c0 ## Install IIS with CGI Support The steps for this are identical to those for the [reverse proxying IIS setup](./iis.md#install) except that you need to enable CGI in the last step, since it isn’t installed by default. For Windows Server, the path is: ![Install CGI in IIS](./cgi-install-iis.png) The path is similar on the consumer-focused versions of Windows, once you get to that last step. ## Setup 1. Install the Fossil executable to `c:\inetpub\wwwroot\bin` on the web server. We can’t use an executable you might already have because IIS runs under a separate user account, so we need to give that executable special permissions, and that’s easiest to do under the IIS tree: ![IIS fossil.exe execute permission](./cgi-bin-perm.png) 2. In IIS Manager (a.k.a. `INETMGR`) drill down into the Sites folder in the left-side pane and right-click your web site’s configuration. (e.g. “Default Web Siteâ€) 3. On that menu say “Add Virtual Directory.†Give it the alias “`cgi`†and point it at a suitable directory, such as “`c:\inetpub\wwwroot\cgi`â€. 4. Double-click the “Handler Mappings†icon, then in the right-side pane, click “Add Script Map...†Apply the following settings: ![IIS script map dialog](./cgi-script-map.png) The Executable path must point to the path we set up in step 1, not to some other `fossil.exe` you may have elsewhere on your system. You will need to change the default “`*.dll`†filter in the Open dialog to “`*.exe`†in order to see it when browsing via the “`...`†button. 5. Create a file called `repo.fslcgi` within the CGI directory you chose in step 3, with a single line like this: repository: c:\Users\SOMEONE\museum\repo.fossil Give the actual path to the repository, of course. 6. Up at the top level of IIS Manager, double-click the “ISAPI and CGI Restrictions†icon, then click “Add...†in the right-side pane. Give the script you just created permission to execute: ![IIS CGI execute permission](./cgi-exec-perm.png) 7.

The first part of the scheme below sets Fossil up as an HTTP server, so you might be wondering why you wouldn’t just modify that to make it listen on all network interfaces on TCP port 80, so you can avoid the need for IIS entirely. For simple use cases, you can indeed do without IIS, but there are several use cases where adding it is helpful: 1. Proxying Fossil with IIS lets you [add TLS encryption][tls], which [Fossil does not currently speak](../../ssl.wiki) in its server role. 2. The URL rewriting we do below allows Fossil to be part of a larger site already being served with IIS. 3. You can have a mixed-mode site, with Fossil acting as a powerful dynamic content management service and IIS as a fast static content server. The pure-Fossil alternative requires that you check all of your static content into Fossil as versioned or unversioned artifacts. This article shows how you can get any combination of those benefits by using IIS as a reverse proxy for `fossil server`. There are other ways to use IIS to serve Fossil, such as [via CGI](./cgi.md). ## Background Fossil Service Setup You will need to have the Fossil HTTP server running in the background, serving some local repository, bound to localhost on a fixed high-numbered TCP port. For the purposes of testing, simply start it by hand in your command shell of choice: fossil serve --port 9000 --localhost repo.fossil That command assumes you’ve got `fossil.exe` in your `%PATH%` and you’re in a directory holding `repo.fossil`. See [the platform-independent instructions](../any/none.md) for further details. For a more robust setup, we recommend that you [install Fossil as a Windows service](./service.md), which will allow Fossil to start at system boot, before anyone has logged in interactively. ## <a name="install"></a>Install IIS IIS might not be installed in your system yet, so follow the path appropriate to your host OS. We’ve tested only the latest Microsoft OSes as of the time of this writing, but the basic process should be similar on older OSes. ### Windows Server 2019 1. Start “Server Manager†2. Tell it you want to “Add roles and features†3. Select “Role-based or feature-based installation†4. Select your local server 5. In the Server Roles section, enable “Web Server (IIS)†### Windows 1. Open Control Panel 2. Go to “Programs†3. Select “Turn Windows features on or off†in the left-side pane 4. In the “Windows Features†dialog, enable “Internet Information Services†The default set of IIS features there will suffice for this tutorial, but you might want to enable additional features. ## Setting up the Proxy The stock IIS setup doesn’t have reverse proxying features, but they’re easily added through extensions. You will need to install the [Application Request Routing][arr] and [URL Rewrite][ure] extensions. In my testing here, URL Rewrite showed up immediately after installing it, but I had to reboot the server to get ARR to show up. (Yay Windows.) You can install these things through the direct links above, or you can do it via the Web Platform Installer feature of IIS Manager (a.k.a. `INETMGR`). Set these extensions up in IIS Manager like so: 1. Double-click the “Application Request Routing Cache†icon. 2. Right-click in the window that results, and select “Server Proxy Settings...†3. Check the “Enable Proxy†box in the dialog. Click the “Apply†text in the right-side pane. 4. Return to the top server-level configuration area of IIS Manager and double-click the “URL Rewrite†icon. Alternately, you might find “URL Rewrite†in the right-side pane from within the ARR settings. 5. Right click in the window that results, and click “Add Rule(s)...†Tell it you want a “Blank rule†under “Inbound rulesâ€. 6. In the dialog that results, create a new rule called “Fossil repo proxy.†Set the “Pattern†to “`^(.*)$`†and “Rewrite URL†set to “`http://localhost:9000/{R:1}`â€. That tells it to take everything in the path part of the URL and send it down to localhost:9000, where `fossil server` is listening. 7. Click “Apply†in the right-side pane, then get back to the top level configuration for the server, and click “Restart†in that same pane. At this point, if you go to `http://localhost/` in your browser, you should see your Fossil repository’s web interface instead of the default IIS web site, as before you did all of the above. This is a very simple configuration. You can do more complicated and interesting things with this, such as redirecting only `/code` URLs to Fossil by setting the Pattern in step 6 to “`^/code(.*)$`â€. (You would also need to pass `--baseurl http://example.com/code` in the `fossil server` command to make this work properly.) IIS would then directly serve all other URLs. You could also intermix ASP.NET applications in the URL scheme in this way. See the documentation on [URL Rewrite rules][urr] for more ideas. *[Return to the top-level Fossil server article.](../)* [arr]: https://www.iis.net/downloads/microsoft/application-request-routing [tls]: https://docs.microsoft.com/en-us/iis/manage/configuring-security/understanding-iis-url-authorization [ure]: https://www.iis.net/downloads/microsoft/url-rewrite [urr]: https://docs.microsoft.com/en-us/iis/extensions/url-rewrite-module/creating-rewrite-rules-for-the-url-rewrite-module |

This problem has two halves: ## No App Startup Without Desktop The easy methods for starting a program in Windows at system start all require an interactive desktop. There is no *easy* way to start an arbitrary program on Windows at boot before anyone has logged in. In Unix terms, Windows has no simple equivalent to [the `/etc/rc.local` file][rcl]. You can partially get around the first problem by setting your `fossil server` call up as one of the user’s interactive startup items. Windows 10 has its own [idiosyncratic way of doing this][si10], and in older systems you have [several alternatives to this][si7]. Regardless of the actual mechanism, these will cause the Fossil standalone HTTP server to start on an *interactive desktop login* only. While you’re sitting at the Windows login screen, the Fossil server is *down*. [rcl]: http://nixdoc.net/man-pages/FreeBSD/man8/rc.local.8.html [si10]: https://www.tenforums.com/tutorials/2944-add-delete-enable-disable-startup-items-windows-10-a.html [si7]: https://www.wikihow.com/Change-Startup-Programs-in-Windows-7 ## No Simple Background Mode Windows also lacks a direct equivalent of the Bourne shell’s “`&`†control operator to run a program in the background, which you can give in Unix’s `rc.local` file, which is just a normal Bourne shell script. By “background,†I mean “not attached to any interactive user’s login session.†When the `rc.local` script exits in Unix, any program it backgrounded *stays running*. There is no simple and direct equivalent to this mechanism in Windows. If you set `fossil server` to run on interactive login, as above, it will shut right back down again when that user logs back out. With Windows 10, it’s especially problematic because you can no longer make the OS put off updates arbitrarily: your Fossil server will go down every time Windows Update decides it needs to reboot your computer, and then Fossil service will *stay* down until someone logs back into that machine interactively. ## Better Solutions Because of these problems, we only recommend setting `fossil server` up on Windows this way when you’re a solo developer or you work in a small office where everyone arrives more or less at the same time each day, and everyone goes home about the same time each day, so that one user can keep the Fossil server up through the working day. If your needs go at all beyond this, you should expect proper “server†behavior, which you can get on Windows by [registering Fossil as a Windows service](./service.md), which solves the interactive startup and shutdown problems above, at a bit of complexity over the Startup Items method. You may also want to consider putting that service behind [an IIS front-end proxy](./iis.md) to add additional web serving features. *[Return to the top-level Fossil server article.](../)* |

You have Administrative access to a Windows 2012r2 or above server. 2. You have PowerShell 5.1 or above installed. ## Place Fossil on Server However you obtained your copy of Fossil, it is recommended that you follow Windows conventions and place it within `\Program Files\FossilSCM`. Since Fossil 2.10 is a 64bit binary, this is the proper location for the executable. This way Fossil is at an expected location and you will have minimal issues with Windows interfering in your ability to run Fossil as a service. You will need Administrative rights to place fossil at the recommended location. If you will only be running Fossil as a service, you do not need to add this location to the path, though you may do so if you wish. ## Installing Fossil as a Service Luckily the hard work to use Fossil as a Windows Service has been done by the Fossil team. We simply have to install it with the proper command line options. Fossil on Windows has a command `fossil winsrv` to allow installing Fossil as a service on Windows. This command is only documented on the windows executable of Fossil. You must also run the command as administrator for it to be successful. ### Fossil winsrv Example The simplest form of the command is: ``` fossil winsrv create --repository D:/Path/to/Repo.fossil ``` This will create a windows service named 'Fossil-DSCM' running under the local system account and accessible on port 8080 by default. `fossil winsrv` can also start, stop, and delete the service. For all available options, please execute `fossil help winsrv` on a windows install of Fossil. If you wish to server a directory of repositories, the `fossil winsrv` command requires a slightly different set of options vs. `fossil server`: ``` fossil winsrv create --repository D:/Path/to/Repos --repolist ``` <a name='PowerShell'></a> ### Advanced service installation using PowerShell As great as `fossil winsrv` is, it does not have one to one reflection of all of the `fossil server` [options](/help?cmd=server). When you need to use some of the more advanced options, such as `--https`, `--skin`, or `--extroot`, you will need to use PowerShell to configure and install the Windows service. PowerShell provides the [New-Service](https://docs.microsoft.com/en-us/powershell/module/microsoft.powershell.management/new-service?view=powershell-5.1) command, which we can use to install and configure Fossil as a service. The below should all be entered as a single line in an Administrative PowerShell console. ```PowerShell New-Service -Name fossil -DisplayName fossil -BinaryPathName '"C:\Program Files\FossilSCM\fossil.exe" server --port 8080 --repolist "D:/Path/to/Repos"' -StartupType Automatic ``` Please note the use of forward slashes in the repolist path passed to Fossil. Windows will accept either back slashes or forward slashes in path names, but Fossil has a preference for forward slashes. The use of `--repolist` will make this a multiple repository server. If you want to serve only a single repository, then leave off the `--repolist` parameter and provide the full path to the proper repository file. Other options are listed in the [fossil server](/help?cmd=server) documentation. The service will be installed by default to use the Local Service account. Since Fossil only needs access to local files, this is fine and causes no issues. The service will not be running once installed. You will need to start it to proceed (the `-StartupType Automatic` parameter to `New-Service` will result in the service auto-starting on boot). This can be done by entering ```PowerShell Start-Service -Name fossil ``` in the PowerShell console. Congratulations, you now have a base http accessible Fossil server running on Windows. *[Return to the top-level Fossil server article.](../)* |

It is recommended for public repositories to go to the extra step of configuring stunnel to provide a proper HTTPS setup. ## Assumptions 1. You have Administrative access to a Windows 2012r2 or above server. 2. You have PowerShell 5.1 or above installed. 3. You have acquired a certificate either from a Public CA or an Internal CA. These instructions were tested with Fossil 2.10 and stunnel 5.55. Other versions may not function in a similar manner. There is a bug in Fossil 2.9 and earlier that prevents these versions of Fossil from properly constructing https URLs when used with stunnel as a proxy. Please make sure you are using Fossil 2.10 or later on Windows. ## Configure Fossil Service for https Due to the need for the `--https` option for successfully using Fossil with stunnel, we will use [Advanced service installation using PowerShell](./service.md#PowerShell). We will need to change the command to install the Fossil Service to configure it properly for use with stunnel as an https proxy. Run the following: ```PowerShell New-Service -Name fossil-secure -DisplayName fossil-secure -BinaryPathName '"C:\Program Files\FossilSCM\fossil.exe" server --localhost --port 9000 --https --repolist "D:/Path/to/Repos"' -StartupType Automatic ``` The use of `--localhost` means Fossil will only listen for traffic on the local host on the designated port - 9000 in this case - and will not respond to network traffic. Using `--https` will tell Fossil to generate HTTPS URLs rather than HTTP ones. `New-Service` does not automatically start a service on install, so you will need to enter the following to avoid rebooting the server: ```PowerShell Start-Service -Name fossil-secure ``` ## Install stunnel 5.55 Download stunnel from the [downloads](https://www.stunnel.org/downloads.html) page. Select the latest stunnel windows package (at the time of writing this is `stunnel-5.55-win64-installer.exe`). Execute the installer and make sure you install openSSL tools when you install stunnel. You will need this to convert your certificate from PFX to PEM format. Even though the installer says it is for win64, it installs stunnel by default to `\Program Files (x86)\stunnel`. ## Get your certificate ready for Stunnel Whether you use a Public Certificate Authority or Internal Certificate Authority, the next step is exporting the certificate from Windows into a format useable by Stunnel. ### Export Certificate from Windows If your certificate is installed via Windows Certificate Management, you will need to export the certificate into a usable format. You can do this either using the Windows Certificate Management Console, or PowerShell. #### Certificate Management Console Start `mmc.exe` as an Administrator. Select 'File>Add/Remove Snapin', select 'Certificates' from the list, and click 'Add'. Select 'Computer Account', 'Next', 'Local Computer', and then 'Finish'. In the Console Root, expand 'Certificates', then 'Personal', and select 'Certificates'. In the middle pane find and select your certificate. Right click the certificate and select 'All Tasks>Export'. You want to export as PFX the Private Key, include all certificates in the certification path, and use a password only to secure the file. Enter a path and file name to a working directory and complete the export. Continue with [Convert Certificate from PFX to PEM](#convert). #### PowerShell If you know the Friendly Name of the Certificate this is relatively easy. Since you need to export the private key as well, you must run the following from an Administrative PowerShell console. ```PowerShell $passwd = ConvertTo-SecureString -string "yourpassword" -Force -AsPlainText Get-ChildItem Cert:\LocalMachine\My | Where{$_.FriendlyName -eq "FriendlyName"} | Export-PfxCertificate -FilePath fossil-scm.pfx -Password $passwd ``` You will now have your certificate stored as a PFX file. <a name="convert"></a> ### Convert Certificate from PFX to PEM For this step you will need the openssl tools that were installed with stunnel. ```PowerShell # Add stunnel\bin directory to path for this session. $env:PATH += ";${env:ProgramFiles(x86)}\stunnel\bin" # Export Private Key openssl.exe pkcs12 -in fossil-scm.pfx -out fossil-scm.key -nocerts -nodes # Export the Certificate openssl.exe pkcs12 -in fossil-scm.pfx -out fossil-scm.pem -nokeys ``` Now move `fossil-scm.key` and `fossil-scm.pem` to your stunnel config directory (by default this should be located at `\Program Files (x86)\stunne\config`). ## stunnel Configuration Use the reverse proxy configuration given in the generic [Serving via stunnel document](../any/stunnel.md#proxy). On Windows, the `stunnel.conf` file is located at `\Program Files (x86)\stunnel\config`. You will need to modify it to point at the PEM and key files generated above. After completing the above configuration restart the stunnel service in Windows with the following: ```PowerShell Restart-Service -Name stunnel ``` ## Open up port 443 in the Windows Firewall The following instructions are for the [Windows Advanced Firewall](https://docs.microsoft.com/en-us/windows/security/threat-protection/windows-firewall/windows-firewall-with-advanced-security). If you are using a different Firewall, please consult your Firewall documentation for how to open port 443 for inbound traffic. The following command should be entered all on one line. ```PowerShell New-NetFirewallRule -DisplayName "Allow Fossil Inbound" -Description "Allow Fossil inbound on port 443 using Stunnel as TLS Proxy." -Direction Inbound -Protocol TCP -LocalPort 443 -Action Allow -Program "C:\Program Files (x86)\Stunnel\bin\stunnel.exe" ``` You should now be able to access your new Fossil Server via HTTPS. *[Return to the top-level Fossil server article.](../)* |

These extensions work like any other CGI program, except that they also have access to the Fossil login information and can (optionally) leverage the "skins" of Fossil so that they appear to be more tightly integrated into the project. An example of where this is useful is the [https://sqlite.org/src/ext/checklist|checklist application] on the [https://sqlite.org/|SQLite] project. The checklist helps the SQLite developers track which release tests have passed, or failed, or are still to be done. The checklist program began as a stand-alone CGI which kept its own private user database and implemented its own permissions and login system and provided its own CSS. By converting checklist into a Fossil extension, the same login that works for the [https://sqlite.org/src|main SQLite source repository] also works for the checklist. Permission to change elements of the checklist is tied on permission to check-in to the main source repository. And the standard Fossil header menu and footer appear on each page of the checklist. <h2>2.0 How It Works</h2> CGI Extensions are disabled by default. An administrator activates the CGI extension mechanism by specifying an "Extension Root Directory" or "extroot" as part of the server setup. If the Fossil server is itself run as [./server/any/cgi.md|CGI], then add a line to the [./cgi.wiki#extroot|CGI script file] that says: <blockquote><pre> extroot: <i>DIRECTORY</i> </pre></blockquote> Or, if the Fossil server is being run using the "[./server/any/none.md|fossil server]" or "[./server/any/none.md|fossil ui]" or "[./server/any/inetd.md|fossil http]" commands, then add an extra "--extroot <i>DIRECTORY</i>" option to that command. The <i>DIRECTORY</i> is the DOCUMENT_ROOT for the CGI. Files in the DOCUMENT_ROOT are accessed via URLs like this: <blockquote> https://example-project.org/ext/<i>FILENAME</i> </blockquote> In other words, access files in DOCUMENT_ROOT by appending the filename relative to DOCUMENT_ROOT to the [/help?cmd=/ext|/ext] page of the Fossil server. Files that are readable but not executable are returned as static content. Files that are executable are run as CGI. <h3>2.1 Example #1</h3> The source code repository for SQLite is a Fossil server that is run as CGI. The URL for the source code repository is [https://sqlite.org/src]. The CGI script looks like this: <blockquote><verbatim> #!/usr/bin/fossil repository: /fossil/sqlite.fossil errorlog: /logs/errors.txt extroot: /sqlite-src-ext </verbatim></blockquote> The "extroot: /sqlite-src-ext" line tells Fossil that it should look for extension CGIs in the /sqlite-src-ext directory. (All of this is happening inside of a chroot jail, so putting the document root in a top-level directory is a reasonable thing to do.) When a URL like "https://sqlite.org/src/ext/checklist" is received by the main webserver, it figures out that the /src part refers to the main Fossil CGI script and so it runs that script. Fossil gets the remainder of the URL to work with: "/ext/checklist". Fossil extracts the "/ext" prefix and uses that to determine that this a CGI extension request. Then it takes the leftover "/checklist" part and appends it to the "extroot" to get the filename "/sqlite-src-ext/checklist". Fossil finds that file to be executable, so it runs it as CGI and returns the result. The /sqlite-src-ext/checklist file is a [https://wapp.tcl.tk|Wapp program]. The current source code to the this program can be seen at [https://www.sqlite.org/src/ext/checklist/3070700/self] and recent historical versions are available at [https://sqlite.org/docsrc/finfo/misc/checklist.tcl] with older legacy at [https://sqlite.org/checklistapp/timeline?n=all] There is a cascade of CGIs happening here. The web server that receives the initial HTTP request runs Fossil as a CGI based on the "https://sqlite.org/src" portion of the URL. The Fossil instance then runs the checklist sub-CGI based on the "/ext/checklists" suffix. The output of the sub-CGI is read by Fossil and then relayed on to the main web server which in turn relays the result back to the original client. <h3>2.2 Example #2</h3> The [https://fossil-scm.org/home|Fossil self-hosting repository] is also a CGI that looks like this: <blockquote><verbatim> #!/usr/bin/fossil repository: /fossil/fossil.fossil errorlog: /logs/errors.txt extroot: /fossil-extroot </verbatim></blockquote> The extroot for this Fossil server is /fossil-extroot and in that directory is an executable file named "fileup1" - another [https://wapp.tcl.tk|Wapp] script. (The extension mechanism is not required to use Wapp. You can use any kind of program you like. But the creator of SQLite and Fossil is fond of [https://www.tcl.tk|Tcl/Tk] and so he tends to gravitate toward Tcl-based technologies like Wapp.) The fileup1 script is a demo program that lets the user upload a file using a form, and then displays that file in the reply. There is a link on the page that causes the fileup1 script to return a copy of its own source-code, so you can see how it works. <h2>3.0 CGI Inputs</h2> The /ext extension mechanism is an ordinary CGI interface. Parameters are passed to the CGI program using environment variables. The following standard CGI environment variables are supported: * AUTH_TYPE * AUTH_CONTENT * CONTENT_LENGTH * CONTENT_TYPE * DOCUMENT_ROOT * GATEWAY_INTERFACE * HTTP_ACCEPT * HTTP_ACCEPT_ENCODING * HTTP_COOKIE * HTTP_HOST * HTTP_IF_MODIFIED_SINCE * HTTP_IF_NONE_MATCH * HTTP_REFERER * HTTP_USER_AGENT * PATH_INFO * QUERY_STRING * REMOTE_ADDR * REMOTE_USER * REQUEST_METHOD * REQUEST_URI * SCRIPT_DIRECTORY * SCRIPT_FILENAME * SCRIPT_NAME * SERVER_NAME * SERVER_PORT * SERVER_PROTOCOL Do a web search for "[https://duckduckgo.com/?q=cgi+environment_variables|cgi environment variables]" to find more detail about what each of the above variables mean and how they are used. Live listings of the values of some or all of these environment variables can be found at links like these: * [https://fossil-scm.org/home/test_env] * [https://sqlite.org/src/ext/checklist/top/env] In addition to the standard CGI environment variables listed above, Fossil adds the following: * FOSSIL_CAPABILITIES * FOSSIL_NONCE * FOSSIL_REPOSITORY * FOSSIL_URI * FOSSIL_USER The FOSSIL_USER string is the name of the logged-in user. This variable is missing or is an empty string if the user is not logged in. The FOSSIL_CAPABILITIES string is a list of [./caps/ref.html|Fossil capabilities] that indicate what permissions the user has on the Fossil repository. The FOSSIL_REPOSITORY environment variable gives the filename of the Fossil repository that is running. The FOSSIL_URI variable shows the prefix of the REQUEST_URI that is the Fossil CGI script, or is an empty string if Fossil is being run by some method other than CGI. The [https://sqlite.org/src/ext/checklist|checklist application] uses the FOSSIL_USER environment variable to determine the name of the user and the FOSSIL_CAPABILITIES variable to determine if the user is allowed to mark off changes to the checklist. Only users with check-in permission to the Fossil repository are allowed to mark off checklist items. That means that the FOSSIL_CAPABILITIES string must contain the letter "i". Search for "FOSSIL_CAPABILITIES" in the [https://sqlite.org/src/ext/checklist/top/self|source listing] to see how this happens. If the CGI output is one of the forms for which Fossil inserts its own header and footer, then the inserted header will include a Content Security Policy (CSP) restriction on the use of javascript within the webpage. Any <script>...</script> elements within the CGI output must include a nonce or else they will be suppressed by the web browser. The FOSSIL_NONCE variable contains the value of that nonce. So, in other words, to get javascript to work, it must be enclosed in: <blockquote><verbatim> <script nonce='$FOSSIL_NONCE'>...</script> </verbatim></blockquote> Except, of course, the $FOSSIL_NONCE is replaced by the value of the FOSSIL_NONCE environment variable. <h3>3.1 Input Content</h3> If the HTTP request includes content (for example if this is a POST request) then the CONTENT_LENGTH value will be positive and the data for the content will be readable on standard input. <h2>4.0 CGI Outputs</h2> CGI programs construct a reply by writing to standard output. The first few lines of output are parameters intended for the web server that invoked the CGI. These are followed by a blank line and then the content. Typical parameter output looks like this: <blockquote><verbatim> Status: 200 OK Content-Type: text/html </verbatim></blockquote> CGI programs can return any content type they want - they are not restricted to text replies. It is OK for a CGI program to return (for example) image/png. The fields of the CGI response header can be any valid HTTP header fields. Those that Fossil does not understand are simply relayed back to up the line to the requester. Fossil takes special action with some content types. If the Content-Type is "text/x-fossil-wiki" or "text/x-markdown" then Fossil converts the content from [/wiki_rules|Fossil-Wiki] or [/md_rules|Markdown] into HTML, adding its own header and footer text according to the repository skin. Content of type "text/html" is normally passed straight through unchanged. However, if the text/html content is of the form: <blockquote><verbatim> <div class='fossil-doc' data-title='DOCUMENT TITLE'> ... HTML content there ... </div> </verbatim></blockquote> In other words, if the outer-most markup of the HTML is a <div> element with a single class of "fossil-doc", then Fossil will adds its own header and footer to the HTML. The page title contained in the added header will be extracted from the "data-title" attribute. Except for the three cases noted above, Fossil makes no changes or additions to the CGI-generated content. Fossil just passes the verbatim content back up the stack towards the requester. <h2>5.0 Filename Restrictions</h2> For security reasons, Fossil places restrictions on the names of files in the extroot directory that can participate in the extension CGI mechanism: 1. Filenames must consist of only ASCII alphanumeric characters, ".", "_", and "-", and of course "/" as the file separator. Files with names that includes spaces or other punctuation or special characters are ignored. 2. No element of the pathname can begin with "." or "-". Files or directories whose names begin with "." or "-" are ignored. If a CGI program requires separate data files, it is safe to put those files in the same directory as the CGI program itself as long as the names of the data files contain special characters that cause them to be ignored by Fossil. <h2>6.0 Trouble-Shooting Hints</h2> Remember that the /ext will return any file in the extroot directory hierarchy as static content if the file is readable but not executable. When initially setting up the /ext mechanism, it is sometimes helpful to verify that you are able to receive static content prior to starting work on your CGIs. Also remember that CGIs must be executable files. Fossil likes to run inside a chroot jail, and will automatically put itself inside a chroot jail if it can. The sub-CGI program will also run inside this same chroot jail. Make sure all embedded pathnames have been adjusted accordingly and that all resources needed by the CGI program are available within the chroot jail. If anything goes wrong while trying to process an /ext page, Fossil returns a 404 Not Found error with no details. However, if the requester is logged in as a user that has <b>[./caps/ref.html#D | Debug]</b> capability then additional diagnostic information may be included in the output. If the /ext page has a "fossil-ext-debug=1" query parameter and if the requester is logged in as a user with Debug privilege, then the CGI output is returned verbatim, as text/plain and with the original header intact. This is useful for diagnosing problems with the CGI script. |

They are set with the <tt>fossil settings</tt> command, or through the web interface in the Settings page in the Admin section. For a list of all settings, view the Settings page, or type <tt>fossil help settings</tt> from the command line. <h3>Repository settings</h3> Settings are set on a per-repository basis. When you clone a repository, a subset of settings are copied to your local repository. If you make a change to a setting on your local repository, it is not synced back to the server when you <tt>push</tt> or <tt>sync</tt>. If you make a change on the server, you need to manually make the change on all repositories which are cloned from this repository. You can also set a setting globally on your local machine. The value will be used for all repositories cloned to your machine, unless overridden explicitly in a particular repository. Global settings can be set by using the <tt>-global</tt> option on the <tt>fossil settings</tt> command. <h3>"Versionable" settings</h3> Most of the settings control the behaviour of fossil on your local machine, largely acting to reflect your preference on how you want to use Fossil, how you communicate with the server, or options for hosting a repository on the web. However, for historical reasons, some settings affect how you work with versioned files. These are <tt>allow-symlinks</tt>, <tt>binary-glob</tt>, <tt>crlf-glob</tt>, <tt>crnl-glob</tt>, <tt>empty-dirs</tt>, <tt>encoding-glob</tt>, <tt>ignore-glob</tt>, <tt>keep-glob</tt> and <tt>manifest</tt>. The most important is <tt>ignore-glob</tt> which specifies which files should be ignored when looking for unmanaged files with the <tt>extras</tt> command. Because these options can change over time, and the inconvenience of replicating changes, these settings are "versionable". As well as being able to be set using the <tt>settings</tt> command or the web interface, you can create versioned files in the <tt>.fossil-settings</tt> subdirectory of the check-out root, named with the setting name. The contents of the file is the value of the setting, and these files are checked in, committed, merged, and so on, as with any other file. Where a setting is a list of values, such as <tt>ignore-glob</tt>, you can use a newline as a separator as well as a comma. For example, to set the list of ignored files, create a <tt>.fossil-settings/ignore-glob</tt> file where each line contains a glob for ignored files. If you set the value of a setting using the <tt>settings</tt> command as well as a versioned file, the versioned setting will take precedence. A warning will be displayed. |

Fossil purposely makes it difficult for users to delete content. Old content is part of the project's <i>*ahem*</i> fossil record and should be maintained indefinitely to maintain an accurate history of the project. Nevertheless, there may occasionally arise legitimate reasons for deleting content. Such reasons include: * Spammers inserted inappropriate content into a wiki page, forum post, or ticket. Fossil lets you easily hide or amend such content, but since it is not a legitimate part of the project's history, there is no value in keeping it, so it is best removed permanently. * A file that contains trade secrets or that is under someone else's copyright was accidentally committed and needs to be backed out. * A malformed control artifact was inserted and is disrupting the operation of Fossil. <h2>Alternatives</h2> All of these are rare cases: Fossil is [./antibot.wiki | designed to foil spammers up front], legally problematic check-ins should range from rare to nonexistent, and you have to go way out of your way to force Fossil to insert bad control artifacts. Therefore, before we get to methods of permanently deleting content from a Fossil repos, let's give some alternatives that usually suffice, which don't damage the project's fossil record: <ul> <li><p>When a forum post or wiki article is "deleted," what actually happens is that a new empty version is added to the Fossil [./blockchain.md | block chain]. The web interface interprets this as "deleted," but the prior version remains available if you go digging for it.</p></li> <li><p>When you close a ticket, it's marked in a way that causes it to not show up in the normal ticket reports. You usually want to give it a Resolution such as "Rejected" when this happens, plus possibly a comment explaining why you're closing it. This is all new information added to the ticket, not deletion.</p></li> <li><p>When you <tt>fossil rm</tt> a file, a new manifest is checked into the repository with the same file list as for the prior version minus the "removed" file. The file is still present in the repository; it just isn't part of that version forward on that branch.</p></li> <li><p>If you make a bad check-in, you can shunt it off to the side by amending it to put it on a different branch, then continuing development on the prior branch: <p> <tt>$ fossil amend abcd1234 --branch BOGUS --hide<br> $ fossil up trunk</tt> <p> The first command moves check-in ID <tt>abcd1234</tt> (and any subsequent check-ins on that branch!) to a branch called <tt>BOGUS</tt>, then hides it so it doesn't show up on the timeline. You can call this branch anything you like, and you can re-use the same name as many times as you like. No content is actually deleted: it's just shunted off to the side and hidden away. You might find it easier to do this from the Fossil web UI in the "edit" function for a check-in. <p> The second command returns to the last good check-in on that branch so you can continue work from that point.</p></li> <li><p>When the check-in you want to remove is followed by good check-ins on the same branch, you can't use the previous method, because it will move the good check-ins, too. The solution is: <p> <tt>$ fossil merge --backout abcd1234</tt> <p>That creates a diff in the check-out directory that backs out the bad check-in <tt>abcd1234</tt>. You then fix up any merge conflicts, build, test, etc., then check the reverting change into the repository. Again, nothing is actually deleted; you're just adding more information to the repository which corrects a prior check-in.</p></li> </ul> <h2>Shunning</h2> Fossil provides a mechanism called "shunning" for removing content from a repository. Every Fossil repository maintains a list of the hash names of "shunned" artifacts. Fossil will refuse to push or pull any shunned artifact. Furthermore, all shunned artifacts (but not the shunning list itself) are removed from the repository whenever the repository is reconstructed using the "rebuild" command. <h3>Shunning lists are local state</h3> The shunning list is part of the local state of a Fossil repository. In other words, shunning does not propagate to a remote repository using the normal "sync" mechanism. An artifact can be shunned from one repository but be allowed to exist in another. The fact that the shunning list does not propagate is a security feature. If the shunning list propagated then a malicious user (or a bug in the fossil code) might introduce a shun record that would propagate through all repositories in a network and permanently destroy vital information. By refusing to propagate the shunning list, Fossil ensures that no remote user will ever be able to remove information from your personal repositories without your permission. The shunning list does not propagate to a remote repository by the normal "sync" mechanism, but it is still possible to copy shuns from one repository to another using the "configuration" command: <b>fossil configuration pull shun</b> <i>remote-url</i><br> <b>fossil configuration push shun</b> <i>remote-url</i> The two command above will pull or push shunning lists from or to the <i>remote-url</i> indicated and merge the lists on the receiving end. "Admin" privilege on the remote server is required in order to push a shun list. In contrast, the shunning list will be automatically received by default as part of a normal client "pull" operation unless disabled by the "<tt>auto-shun</tt>" setting. Note that the shunning list remains in the repository even after the shunned artifact has been removed. This is to prevent the artifact from being reintroduced into the repository the next time it syncs with another repository that has not shunned the artifact. <h3>Managing the shunning list</h3> The complete shunning list for a repository can be viewed by a user with "admin" privilege on the "/shun" URL of the web interface to Fossil. That URL is accessible under the "Admin" button on the default menu bar. Items can be added to or removed from the shunning list. "Sync" operations are inhibited as soon as the artifact is added to the shunning list, but the content of the artifact is not actually removed from the repository until the next time the repository is rebuilt. When viewing individual artifacts with the web interface, "admin" |

This is most true for repositories accessed over the Internet, especially if they will be accessed from edge networks you do not control, since that admits of various forms of [https://en.wikipedia.org/wiki/Man-in-the-middle_attack|man in the middle attack]. TLS protects the credentials used to access the server, prevents eavesdropping, prevents in-flight data modification, prevents server identify spoofing, and more. There are two major aspects to this, both of which have to be addressed in different ways. Those are the subjects of the next two major sections. <h2 id="client">Fossil TLS Configuration: Client Side</h2> Fossil itself has built-in support for TLS on the client side only. That is to say, you can build it against [https://www.openssl.org/|the OpenSSL library], which will allow it to clone and sync with a remote Fossil repository via <tt>https</tt> URIs. <h3 id="openssl-bin">Building Against OpenSSL Automatically</h3> The <tt>configure</tt> script will attempt to find OpenSSL on your system automatically. It first tries asking the <tt>pkg-config</tt> system where the OpenSSL development files are, and if that fails, it falls back to looking through a list of likely directories. If it can't find the files it needs, the most common solution is to install the OpenSSL development package on your system via your OS's package manager. Examples: * <b>RHEL & Fedora</b>: <tt>sudo yum install openssl-devel</tt> * <b>Debian & Ubuntu</b>: <tt>sudo apt install libssl-dev</tt> * <b>FreeBSD</b>: <tt>su -c 'pkg install openssl'</tt> * <b>macOS</b>: <tt>sudo brew install openssl</tt> * <b>Cygwin</b>: Install <tt>openssl-devel</tt> via Cygwin's <tt>setup-*.exe</tt> program The macOS case requires explanation. Apple last shipped OpenSSL develpoment files in OS X 10.6 (Snow Leopard), choosing to deprecate it from that point forward. (Apple wants you to use their proprietary platform-specific encryption methods instead.) Since macOS has no built-in package manager, a number have sprung up out of the FOSS world. It is not known to this author whether Fossil's current build system can find OpenSSL as installed with any of these other package managers, so unless you have a particular reason to avoid it, we recomend that you use [https://brew.sh|Homebrew] on macOS to install OpenSSL as above. Fossil's build system will seek it out and use it automatically. <h3 id="openssl-src">Building Against a Non-Platform Version of OpenSSL</h3> The Fossil build system has a few other methods for finding OpenSSL when the automatic methods fail or when you'd prefer that Fossil use a different version of OpenSSL than the one Fossil's build system picks on its own. A good reason to do this is when the Fossil build system finds a functioning version of OpenSSL which is nevertheless unsuitable. One common case is that your OS is sufficiently outdated that the platform version of OpenSSL can no longer communicate with remote systems adhering to the latest advice on secure communications. An old OpenSSL might not support any of the [https://en.wikipedia.org/wiki/Cipher_suite|cipher suites] the remote Fossil repository's HTTPS proxy is willing to offer, for example, so that even though both sides are speaking a variant of TLS/SSL, the peers cannot come to an agreement on the cryptography. If you've installed the OpenSSL development files somewhere that Fossil's build system cannot find on its own, you can clue it in by passing the <tt>--with-openssl</tt> option to the <tt>configure</tt> script. Type <tt>./configure --help</tt> for details. Another option is to download the source code to OpenSSL and build Fossil against that private version of OpenSSL: <pre> cd compat # relative to the Fossil source tree root tar xf /path/to/openssl-*.tar.gz ln -fs openssl-x.y.z openssl cd openssl ./config # or, e.g. ./Configure darwin64-x86_64-cc make -j11 cd ../.. ./configure --with-openssl=tree make -j11 </pre> That will get you a Fossil binary statically linked to this in-tree version of OpenSSL. Beware, taking this path typically opens you up to new problems, which are conveniently covered in the next section! <h3 id="certs">Certificates</h3> To verify the identify of a server, TLS uses [https://en.wikipedia.org/wiki/X.509#Certificates|X.509 certificates], a scheme that depends on a trust hierarchy of so-called [https://en.wikipedia.org/wiki/Certificate_authority | Certificate Authorities]. The tree of trust relationships ultimately ends in the CA roots, which are considered the ultimate arbiters of who to trust in this scheme. The question then is, what CA roots does Fossil trust? If you are using a self-signed certificate, Fossil will initially not know that it can trust your certificate, so you'll be asked if you want to accept the certificate the first time you communicate with the server. Verify the certificate fingerprint is correct, then answer "always" if you want Fossil to remember your decision. If you are cloning from or syncing to Fossil servers that use a certificate signed by a well-known CA or one of its delegates, Fossil still has to know which CA roots to trust. When this fails, you get an error message that looks like this in Fossil 2.11 and newer: <pre> Unable to verify SSL cert from www.fossil-scm.org subject: CN = sqlite.org issuer: C = US, O = Let's Encrypt, CN = Let's Encrypt Authority X3 sha256: bf26092dd97df6e4f7bf1926072e7e8d200129e1ffb8ef5276c1e5dd9bc95d52 accept this cert and continue (y/N)? </pre> In older versions, the message was much longer and began with this line: <pre> SSL verification failed: unable to get local issuer certificate </pre> Fossil relies on the OpenSSL library to have some way to check a trusted list of CA signing keys. There are two common ways this fails: # <p>The OpenSSL library Fossil is linked to doesn't have a CA signing key set at all, so that it initially trusts no certificates at all.</p> # <p>The OpenSSL library does have a CA cert set, but your Fossil server's TLS certificate was signed by a CA that isn't in that set.</p> A common reason to fall into the second trap is that you're using certificates signed by a local private CA, as often happens in large enterprises. You can solve this sort of problem by getting your local CA's signing certificate in PEM format and pointing OpenSSL at it: <pre> fossil set --global ssl-ca-location /path/to/local-ca.pem </pre> The use of <tt>--global</tt> with this option is common, since you may have multiple reposotories served under certificates signed by that same CA. However, if you have a mix of publicly-signed and locally-signed certificates, you might want to drop the <tt>--global</tt> flag and set this option on a per-repository basis instead. A common way to run into the broader first problem is that you're on FreeBSD, which does not install a CA certificate set by default, even as a dependency of the OpenSSL library. If you're using a certificate signed by one of the major public CAs, you can solve this by installing the <tt>ca_root_nss</tt> package. That package contains the Mozilla NSS certificate bundle, which gets installed in a location that OpenSSL checks by default, so you don't need to change any Fossil settings. (This is the same certificate set that ships with Firefox, by the way.) The same sort of thing happens with the Windows build of OpenSSL, but for a different core reason: Windows does ship with a stock CA certificate set, but it's not in a format that OpenSSL understands how to use. Rather than try to find a way to convert the data format, you may find it acceptable to use the same Mozilla NSS cert set. I do not know of a way to easily get this from Mozilla themselves, but I did find a [https://curl.haxx.se/docs/caextract.html|third party source] for the <tt>cacert.pem</tt> file. I suggest placing the file into your Windows user home directory so that you can then point Fossil at it like so: <pre> fossil set --global ssl-ca-location %userprofile%\cacert.pem </pre> This can also happen if you've linked Fossil to a version of OpenSSL [#openssl-src|built from source]. That same <tt>cacert.pem</tt> fix can work in that case, too. When you build Fossil on Linux platforms against the binary OpenSSL package provided with the OS, you typically get a root cert store along with the platform OpenSSL package, either built-in or as a hard dependency. <h4>Client-Side Certificates</h4> You can also use client side certificates to add an extra layer of authentication, over and above Fossil's built in user management. If you are particularly paranoid, you'll want to use this to remove the ability of anyone on the internet from making any request to Fossil. Without presenting a valid client side certificate, the web server won't invoke the Fossil CGI handler. Configure your server to request a client side certificate, and set up a certificate authority to sign your client certificates. For each person who needs to access the repository, create a private key and certificate signed with that CA. The PEM encoded private key and certificate should be stored in a single file, simply by concatenating the key and certificate files. Specify the location of this file with the <tt>ssl-identity</tt> setting, or the <tt>--ssl-identity</tt> option to the <tt>clone</tt> command. If you've password protected the private key, the password will be requested every time you connect to the server. This password is not stored by fossil, as doing so would defeat the purpose of having a password. If you attempt to connect to a server which requests a client certificate, but don't provide one, fossil will show an error message which explains what to do to authenticate with the server. <h2 id="server">Fossil TLS Configuration: Server Side</h2> Fossil's built-in HTTP server feature does not currently have a built-in way to serve via HTTP over TLS, a.k.a. HTTPS, even when you've linked Fossil to OpenSSL. To serve a Fossil repository via HTTPS, you must put it behind some kind of HTTPS proxy. We have a number of documents elsewhere in this repository that cover your options for [./server/ | serving Fossil repositories]. A few of the most useful of these are: * <a id="stunnel" href="./server/any/stunnel.md">Serving via stunnel</a> * <a id="althttpd" href="./server/any/althttpd.md">Serving via stunnel + althttpd</a> * <a id="nginx" href="./server/any/scgi.md">Serving via SCGI (nginx)</a> <h2 id="enforcing">Enforcing TLS Access</h2> To use TLS encryption in cloning and syncing to a remote Fossil repository, be sure to use the <tt>https:</tt> URI scheme in <tt>clone</tt> and <tt>sync</tt> commands. If your server is configured to serve the repository via both HTTP and HTTPS, it's easy to accidentally use unencrypted HTTP if you forget the all-important 's'. As of Fossil 2.8, there is a setting in the Fossil UI under Admin → Access called "Redirect to HTTPS," which is set to "Off" by default. Changing this only affects web UI access to the Fossil repository. It doesn't affect clones and syncs done via the <tt>http</tt> URI scheme. In Fossil 2.7 and earlier, there was a much weaker form of this setting affecting the <tt>/login</tt> page only. If you're using this setting, you should migrate to the new setting as soon as possible, because the old setting allows multiple ways of defeating it. <b id="rloop">WARNING:</b> Enabling HTTPS redirects at the Fossil repo level while running Fossil behind an HTTPS proxy can result in an infinite redirect loop. It happens when the proxy mechanism presents "<tt>http</tt>" URIs to Fossil, so Fossil issues a redirect, so the browser fetches the page again, causing Fossil to see an "<tt>http</tt>" URI again, so it issues a redirect...'round and 'round it goes until the web browser detects it's in a redirect loop and gives up. This problem prevents you from getting back into the Admin UI to fix it, but there are several ways to fix it: # <p><b>Reset via CLI.</b> You can turn the setting back off from the CLI with the command "<tt>fossil -R /path/to/repo.fossil set redirect-to-https 0</tt>". (Currently doesn't work.)</p> # <p><b>Backup first.</b> This setting is stored in the Fossil repository, so if you make a backup first <i>on the server</i>, you can restore the repo file if enabling this feature creates a redirect loop.</p> # <p><b>Download, fix, and restore.</b> You can copy the remote repository file down to a local machine, use <tt>fossil ui</tt> to fix the setting, and then upload it to the repository server again.</p> It's best to enforce TLS-only access at the front-end proxy level anyway. It not only avoids the problem entirely, it can be significantly more secure. The [./tls-nginx.md|nginx TLS proxy guide] shows one way to achieve this.</p> <h2>Terminology Note</h2> This document is called <tt>ssl.wiki</tt> for historical reasons. The TLS protocol was originally called SSL, and it went through several revisions before being replaced by TLS. Years before this writing, SSL finally became entirely obsolete due to weaknesses in the protocol fixed in the later TLS series of protocols. Some people still use the term "SSL" when they actually mean "TLS," but in the Fossil project, we always use "TLS" except when we must preserve some sort of historical compatibility, as with this document's name in order to avoid broken external URLs. The Fossil TLS-related settings also often use "<tt>ssl</tt>" in their names, for the same reason. This series of protocols is also called "HTTPS" after the URI scheme used to specify "HTTP over TLS." |

Does it use a lot of disk space or bandwidth? Is it scalable? In an attempt to answers these questions, this report looks at several projects that use fossil for configuration management and examines how well they are working. The following table is a summary of the results. (Last updated on 2018-06-04.) Explanation and analysis follows the table. <table border=1> <tr> <th>Project</th> <th>Number Of Artifacts</th> <th>Number Of Check-ins</th> <th>Project Duration<br>(as of 2018-06-04)</th> <th>Uncompressed Size</th> <th>Repository Size</th> <th>Compression Ratio</th> <th>Clone Bandwidth</th> </tr> <tr align="center"> <td>[http://www.sqlite.org/src/timeline | SQLite] <td>77492 <td>20686 <td>6580 days<br>18.02 years <td>5.6 GB <td>70.0 MB <td>80:1 <td>51.1 MB </tr> <tr align="center"> <td>[http://core.tcl.tk/tcl/timeline | TCL] <td>161991 <td>23146 <td>7375 days<br>20.19 years <td>8.0 GB <td>222.0 MB <td>36:1 <td>150.5 MB </tr> <tr align="center"> <td>[/timeline | Fossil] <td>39148 <td>11266 <td>3971 days<br>10.87 years <td>3.8 GB <td>42.0 MB <td>90:1 <td>27.4 MB </tr> <tr align="center"> <td>[http://www.sqlite.org/slt/timeline | SLT] <td>2384 <td>169 <td>3474 days<br>9.51 years <td>2.1 GB <td>145.9 MB <td>14:1 <td>143.4 MB </tr> <tr align="center"> <td>[http://www.sqlite.org/th3.html | TH3] <td>12406 <td>3718 <td>3539 days<br>9.69 years <td>544 MB <td>18.0 MB <td>30:1 <td>14.7 MB </tr> <tr align="center"> <td>[http://www.sqlite.org/docsrc/timeline | SQLite Docs] <td>8752 <td>2783 <td>3857 days<br>10.56 years <td>349.9 MB <td>16.3 MB <td>21:1 <td>13.57 MB </tr> </table> <h2>Measured Attributes</h2> In Fossil, every version of every file, every wiki page, every change to every ticket, and every check-in is a separate "artifact". One way to think of a Fossil project is as a bag of artifacts. Of course, there is a lot more than this going on in Fossil. Many of the artifacts have meaning and are related to other artifacts. But at a low level (for example when synchronizing two instances of the same project) the only thing that matters is the unordered collection of artifacts. In fact, one of the key characteristics of Fossil is that the entire project history can be reconstructed simply by scanning the artifacts in an arbitrary order. The number of check-ins is the number of times that the "commit" command has been run. A single check-in might change a 3 or 4 files, or it might change dozens or hundreds of files. Regardless of the number of files changed, it still only counts as one check-in. The "Uncompressed Size" is the total size of all the artifacts within the repository assuming they were all uncompressed and stored separately on the disk. Fossil makes use of delta compression between related versions of the same file, and then uses zlib compression on the resulting deltas. The total resulting repository size is shown after the uncompressed size. On the right end of the table, we show the "Clone Bandwidth". This is the total number of bytes sent from server back to the client. The number of bytes sent from client to server is negligible in comparison. These byte counts include HTTP protocol overhead. In the table and throughout this article, "GB" means gigabytes (10<sup><small>9</small></sup> bytes) not <a href="http://en.wikipedia.org/wiki/Gibibyte">gibibytes</a> (2<sup><small>30</small></sup> bytes). Similarly, "MB" and "KB" means megabytes and kilobytes, not mebibytes and kibibytes. <h2>Analysis And Supplemental Data</h2> Perhaps the two most interesting data points in the above table are SQLite and SLT. SQLite is a long-running project with long revision chains. Some of the files in SQLite have been edited over a thousand times. Each of these edits is stored as a delta, and hence the SQLite project gets excellent 80:1 compression. SLT, on the other hand, consists of many large (megabyte-sized) SQL scripts that have one or maybe two edits each. There is very little delta compression occurring and so the overall repository compression ratio is much lower. Note also that quite a bit more bandwidth is required to clone SLT than SQLite. For the first nine years of its development, SQLite was versioned by CVS. The resulting CVS repository measured over 320MB in size. So, the developers were surprised to see that the equivalent Fossil project (the first nine years on SQLite) would clone with only 13MB of bandwidth. The "sync" protocol used by fossil has turned out to be surprisingly efficient. A typical check-in on SQLite might use 3 or 4KB of network bandwidth. For example, the [04eef9522386a59e] check-in used a single HTTP request of 2099 bytes and got back a reply of 1116 bytes. The sync protocol is efficient enough that, once cloned, Fossil can easily be used over a dial-up connection. |

Each artifact is identified by a cryptographic hash of its content, expressed as a lower-case hexadecimal string. Synchronization is the process of sharing artifacts between repositories so that all repositories have copies of all artifacts. Because artifacts are unordered, the order in which artifacts are received is unimportant. It is assumed that the hash names of artifacts are unique - that every artifact has a different hash. To a first approximation, synchronization proceeds by sharing lists hash values for available artifacts, then sharing the content of artifacts whose names are missing from one side or the other of the connection. In practice, a repository might contain millions of artifacts. The list of hash names for this many artifacts can be large. So optimizations are employed that usually reduce the number of hashes that need to be shared to a few hundred.</p> <p>Each repository also has local state. The local state determines the web-page formatting preferences, authorized users, ticket formats, and similar information that varies from one repository to another. The local state is not usually transferred during a sync. Except, some local state is transferred during a [/help?cmd=clone|clone] in order to initialize the local state of the new repository. Also, an administrator can sync local state using the [/help?cmd=configuration|config push] and [/help?cmd=configuration|config pull] commands. <a name="crdt"></a> <h3>1.1 Conflict-Free Replicated Datatypes</h3> <p>The "bag of artifacts" data model used by Fossil Fossil is apparently an implementation of a particular [https://en.wikipedia.org/wiki/Conflict-free_replicated_data_type|Conflict-Free Replicated Datatype (CRDT)] called a "G-Set" or "Grow-only Set". The academic literature on CRDTs only began to appear in about 2011, and Fossil predates that research by at least 4 years. But it is nice to know that theorists have now proven that the underlying data model of Fossil can provide strongly-consistent replicas using only peer-to-peer communication and without any kind of central authority.</p> <p>If you are already familiar with CRDTs and were wondering if Fossil used them, the answer is "yes". We just don't call them by that name.</p> <h2>2.0 Transport</h2> <p>All communication between client and server is via HTTP requests. The server is listening for incoming HTTP requests. The client issues one or more HTTP requests and receives replies for each request.</p> <p>The server might be running as an independent server using the <b>server</b> command, or it might be launched from inetd or xinetd using the <b>http</b> command. Or the server might be launched from CGI. (See "[./server/|How To Configure A Fossil Server]" for details.) The specifics of how the server listens for incoming HTTP requests is immaterial to this protocol. The important point is that the server is listening for requests and the client is the issuer of the requests.</p> <p>A single push, pull, or sync might involve multiple HTTP requests. The client maintains state between all requests. But on the server side, each request is independent. The server does not preserve any information about the client from one request to the next.</p> <p>Note: Throughout this article, we use the terms "server" and "client" to represent the listener and initiator of the interaction, respectively. Nothing in this protocol requires that the server actually be a back-room processor housed in a datacenter, nor does the client need to be a desktop or handheld device. For the purposes of this article "client" simply means the repository that initiates the conversation and "server" is the repository that responds. Nothing more.</p> <h4>2.0.1 Encrypted Transport</h4> <p>In the current implementation of Fossil, the server only understands HTTP requests. The client can send either clear-text HTTP requests or encrypted HTTPS requests. But when HTTPS requests are sent, they first must be decrypted by a web server or proxy before being passed to the Fossil server. This limitation may be relaxed in a future release.</p> <h3>2.1 Server Identification</h3> <p>The server is identified by a URL argument that accompanies the push, pull, or sync command on the client. (As a convenience to users, the URL can be omitted on the client command and the same URL from the most recent push, pull, or sync will be reused. This saves |

The nonce is the SHA1 hash of the remainder of the message - all text that follows the newline character that terminates the login card. The signature is the SHA1 hash of the concatenation of the nonce and the users password.</p> <p>For each login card, the server looks up the user and verifies that the nonce matches the SHA1 hash of the remainder of the message. It then checks the signature hash to make sure the signature matches. If everything checks out, then the client is granted all privileges of the specified user.</p> <p>Privileges are cumulative. There can be multiple successful login cards. The session privileges are the bit-wise OR of the privileges of each individual login.</p> <h3>3.3 File Cards</h3> <p>Artifacts are transferred using either "file" cards, or "cfile" or "uvfile" cards. The name "file" card comes from the fact that most artifacts correspond to files that are under version control. The "cfile" name is an abbreviation for "compressed file". The "uvfile" name is an abbreviation for "unversioned file". </p> <h4>3.3.1 Ordinary File Cards</h4> <p>For sync protocols, artifacts are transferred using "file" cards. File cards come in two different formats depending on whether the artifact is sent directly or as a delta from some other artifact.</p> <blockquote> <b>file</b> <i>artifact-id size</i> <b>\n</b> <i>content</i><br> <b>file</b> <i>artifact-id delta-artifact-id size</i> <b>\n</b> <i>content</i> </blockquote> <p>File cards are followed by in-line "payload" data. The content of the artifact or the artifact delta is the first <i>size</i> bytes of the x-fossil content that immediately follow the newline that terminates the file card. </p> <p>The first argument of a file card is the ID of the artifact that is being transferred. The artifact ID is the lower-case hexadecimal representation of the name hash for the artifact. The last argument of the file card is the number of bytes of payload that immediately follow the file card. If the file card has only two arguments, that means the payload is the complete content of the artifact. If the file card has three arguments, then the payload is a delta and second argument is the ID of another artifact that is the source of the delta.</p> <p>File cards are sent in both directions: client to server and server to client. A delta might be sent before the source of the delta, so both client and server should remember deltas and be able to apply them when their source arrives.</p> <h4>3.3.2 Compressed File Cards</h4> <p>A client that sends a clone protocol version "3" or greater will receive artifacts as "cfile" cards while cloning. This card was introduced to improve the speed of the transfer of content by sending the compressed artifact directly from the server database to the client.</p> <p>Compressed File cards are similar to File cards, sharing the same in-line "payload" data characteristics and also the same treatment of direct content or delta content. Cfile cards come in two different formats depending on whether the artifact is sent directly or as a delta from some other artifact.</p> <blockquote> <b>cfile</b> <i>artifact-id usize csize</i> <b>\n</b> <i>content</i><br> <b>cfile</b> <i>artifact-id delta-artifact-id usize csize</i> <b>\n</b> <i>content</i><br> </blockquote> <p>The first argument of the cfile card is the ID of the artifact that is being transferred. The artifact ID is the lower-case hexadecimal representation of the name hash for the artifact. The second argument of the cfile card is the original size in bytes of the artifact. The last argument of the cfile card is the number of compressed bytes of payload that immediately follow the cfile card. If the cfile card has only three arguments, that means the payload is the complete content of the artifact. If the cfile card has four arguments, then the payload is a delta and the second argument is the ID of another artifact that is the source of the delta and the third argument is the original size of the delta artifact.</p> <p>Unlike file cards, cfile cards are only sent in one direction during a clone from server to client for clone protocol version "3" or greater.</p> <h4>3.3.3 Private artifacts</h4> <p>"Private" content consist of artifacts that are not normally synced. However, private content will be synced when the the [/help?cmd=sync|fossil sync] command includes the "--private" option. </p> <p>Private content is marked by a "private" card: <blockquote> <b>private</b> </blockquote> <p>The private card has no arguments and must directly precede a file card that contains the private content.</p> <h4>3.3.4 Unversioned File Cards</h4> <p>Unversioned content is sent in both directions (client to server and server to client) using "uvfile" cards in the following format: <blockquote> <b>uvfile</b> <i>name mtime hash size flags</i> <b>\n</b> <i>content</i> </blockquote> <p>The <i>name</i> field is the name of the unversioned file. The <i>mtime</i> is the last modification time of the file in seconds since 1970. The <i>hash</i> field is the hash of the content for the unversioned file, or "<b>-</b>" for deleted content. The <i>size</i> field is the (uncompressed) size of the content in bytes. The <i>flags</i> field is an integer which is interpreted as an array of bits. The 0x0004 bit of <i>flags</i> indicates that the <i>content</i> is to be omitted. The content might be omitted if it is too large to transmit, or if the sender merely wants to update the modification time of the file without changing the files content. The <i>content</i> is the (uncompressed) content of the file. <p>The receiver should only accept the uvfile card if the hash and size match the content and if the mtime is newer than any existing instance of the same file held by the receiver. The sender will not normally transmit a uvfile card unless all these constraints are true, but the receiver should double-check. <p>A server should only accept uvfile cards if the login user has the "y" write-unversioned permission. <p>Servers send uvfile cards in response to uvgimme cards received from the client. Clients send uvfile cards when they determine that the server needs the content based on uvigot cards previously received from the server. <h3>3.4 Push and Pull Cards</h3> <p>Among the first cards in a client-to-server message are the push and pull cards. The push card tells the server that the client is pushing content. The pull card tells the server that the client wants to pull content. In the event of a sync, both cards are sent. The format is as follows:</p> <blockquote> <b>push</b> <i>servercode projectcode</i><br> <b>pull</b> <i>servercode projectcode</i> </blockquote> <p>The <i>servercode</i> argument is the repository ID for the client. The <i>projectcode</i> is the identifier of the software project that the client repository contains. The projectcode for the client and server must match in order for the transaction to proceed.</p> <p>The server will also send a push card back to the client during a clone. This is how the client determines what project code to put in the new repository it is constructing.</p> <p>The <i>servercode</i> argument is currently unused. <h3>3.5 Clone Cards</h3> <p>A clone card works like a pull card in that it is sent from client to server in order to tell the server that the client wants to pull content. The clone card comes in two formats. Older clients use the no-argument format and newer clients use the two-argument format.</p> <blockquote> <b>clone</b><br> <b>clone</b> <i>protocol-version sequence-number</i> </blockquote> <h4>3.5.1 Protocol 3</h4> <p>The latest clients send a two-argument clone message with a protocol version of "3". (Future versions of Fossil might use larger protocol version numbers.) Version "3" of the protocol enhanced version "2" by introducing the "cfile" card which is intended to speed up clone operations. Instead of sending "file" cards, the server will send "cfile" cards</p> <h4>3.5.2 Protocol 2</h4> <p>The sequence-number sent is the number of artifacts received so far. For the first clone message, the sequence number is 0. The server will respond by sending file cards for some number of artifacts up to the maximum message size. <p>The server will also send a single "clone_seqno" card to the client so that the client can know where the server left off. <blockquote> <b>clone_seqno</b> <i>sequence-number</i> </blockquote> <p>The clone message in subsequent HTTP requests for the same clone operation will use the sequence-number from the clone_seqno of the previous reply.</p> <p>In response to an initial clone message, the server also sends the client a push message so that the client can discover the projectcode for this project.</p> <h4>3.5.3 Legacy Protocol</h4> <p>Older clients send a clone card with no argument. The server responds to a blank clone card by sending an "igot" card for every artifact in the repository. The client will then issue "gimme" cards to pull down all the content it needs. <p>The legacy protocol works well for smaller repositories (50MB with 50,000 artifacts) but is too slow and unwieldy for larger repositories. The version 2 protocol is an effort to improve performance. Further performance improvements with higher-numbered clone protocols are possible in future versions of Fossil. <h3>3.6 Igot Cards</h3> <p>An igot card can be sent from either client to server or from server to client in order to indicate that the sender holds a copy of a particular artifact. The format is:</p> <blockquote> <b>igot</b> <i>artifact-id</i> ?<i>flag</i>? </blockquote> <p>The first argument of the igot card is the ID of the artifact that the sender possesses. The receiver of an igot card will typically check to see if it also holds the same artifact and if not it will request the artifact using a gimme card in either the reply or in the next message.</p> <p>If the second argument exists and is "1", then the artifact identified by the first argument is private on the sender and should be ignored unless a "--private" [/help?cmd=sync|sync] is occurring. <p>The name "igot" comes from the English slang expression "I got" meaning "I have". <h4>3.6.1 Unversioned Igot Cards</h4> <p>Zero or more "uvigot" cards are sent from server to client when synchronizing unversioned content. The format of a uvigot card is as follows: <blockquote> <b>uvigot</b> <i>name mtime hash size</i> </blockquote> <p>The <i>name</i> argument is the name of an unversioned file. The <i>mtime</i> is the last modification time of the unversioned file in seconds since 1970. The <i>hash</i> is the SHA1 or SHA3-256 hash of the unversioned file content, or "<b>-</b>" if the file has been deleted. The <i>size</i> is the uncompressed size of the file in bytes. <p>When the server sees a "pragma uv-hash" card for which the hash does not match, it sends uvigot cards for every unversioned file that it holds. The client will use this information to figure out which unversioned files need to be synchronized. The server might also send a uvigot card when it receives a uvgimme card but its reply message size is already oversized and hence unable to hold the usual uvfile reply. <p>When a client receives a "uvigot" card, it checks to see if the file needs to be transferred from client to server or from server to client. If a client-to-server transmission is needed, the client schedules that transfer to occur on a subsequent HTTP request. If a server-to-client transfer is needed, then the client sends a "uvgimme" card back to the server to request the file content. <h3>3.7 Gimme Cards</h3> <p>A gimme card is sent from either client to server or from server to client. The gimme card asks the receiver to send a particular artifact back to the sender. The format of a gimme card is this:</p> <blockquote> <b>gimme</b> <i>artifact-id</i> </blockquote> <p>The argument to the gimme card is the ID of the artifact that the sender wants. The receiver will typically respond to a gimme card by sending a file card in its reply or in the next message.</p> <p>The "gimme" name means "give me". The imperative "give me" is pronounced as if it were a single word "gimme" in some dialects of English (including the dialect spoken by the original author of Fossil). <h4>3.7.1 Unversioned Gimme Cards</h4> <p>Sync synchronizing unversioned content, the client may send "uvgimme" cards to the server. A uvgimme card requests that the server send unversioned content to the client. The format of a uvgimme card is as follows: <blockquote> <b>uvgimme</b> <i>name</i> </blockquote> <p>The <i>name</i> is the name of the unversioned file found on the server that the client would like to have. When a server sees a uvgimme card, it normally responses with a uvfile card, though it might also send another uvigot card if the HTTP reply is already oversized. <h3>3.8 Cookie Cards</h3> <p>A cookie card can be used by a server to record a small amount of state information on a client. The server sends a cookie to the client. The client sends the same cookie back to the server on its next request. The cookie card has a single argument which is its payload.</p> |

336 337 338 339 340 341 342 | <p>The reqconfig card is normally sent in response to the "fossil configuration pull" command. The format is as follows: <blockquote> <b>reqconfig</b> <i>configuration-name</i> </blockquote> | | | > > > > > > > > > > > > > > > > > > > > | > > | > > > | > > > > > > < > > > > | | | 528 529 530 531 532 533 534 535 536 537 538 539 540 541 542 543 544 545 546 547 548 549 550 551 552 553 554 555 556 557 558 559 560 561 562 563 564 565 566 567 568 569 570 571 572 573 574 575 576 577 578 579 580 581 582 583 584 585 586 587 588 589 590 591 592 593 594 595 596 597 598 599 600 601 602 603 604 605 606 607 608 609 610 611 612 613 614 615 616 617 618 619 620 621 622 623 624 625 626 627 | <p>The reqconfig card is normally sent in response to the "fossil configuration pull" command. The format is as follows: <blockquote> <b>reqconfig</b> <i>configuration-name</i> </blockquote> <p>As of 2018-06-04, the configuration-name must be one of the following values: <table border=0 align="center"> <tr><td valign="top"> <ul> <li> css <li> header <li> footer <li> details <li> logo-mimetype <li> logo-image <li> background-mimetype <li> background-image <li> index-page <li> timeline-block-markup <li> timeline-max-comment <li> timeline-plaintext <li> adunit <li> adunit-omit-if-admin <li> adunit-omit-if-user <ul></td><td valign="top"><ul> <li> th1-docs <li> th1-hooks <li> th1-setup <li> tcl <li> tcl-setup <li> project-name <li> short-project-name <li> project-description <li> index-page <li> manifest <li> binary-glob <li> clean-glob <li> ignore-glob <li> keep-glob <li> crlf-glob <ul></td><td valign="top"><ul> <li> crnl-glob <li> encoding-glob <li> empty-dirs <li> allow-symlinks <li> dotfiles <li> parent-project-code <li> parent-projet-name <li> hash-policy <li> mv-rm-files <li> ticket-table <li> ticket-common <li> ticket-change <li> ticket-newpage <li> ticket-viewpage <li> ticket-editpage <ul></td><td valign="top"><ul> <li> ticket-reportlist <li> ticket-report-template <li> ticket-key-template <li> ticket-title-expr <li> ticket-closed-expr <li> xfer-common-script <li> xfer-push-script <li> xfer-commit-script <li> xfer-ticket-script <li> @reportfmt <li> @user <li> @concealed <li> @shun </ul></td></tr> </table> <p>New configuration-names are likely to be added in future releases of Fossil. If the server receives a configuration-name that it does not understand, the entire reqconfig card is silently ignored. The reqconfig card might also be ignored if the user lacks sufficient privilege to access the requested information. <p>The configuration-names that begin with an alphabetic character refer to values in the "config" table of the server database. For example, the "logo-image" configuration item refers to the project logo image that is configured on the Admin page of the [./webui.wiki | web-interface]. The value of the configuration item is returned to the client using a "config" card. <p>If the configuration-name begins with "@", that refers to a class of values instead of a single value. The content of these configuration items is returned in a "config" card that contains pure SQL text that is intended to be evaluated by the client. <p>The @user and @concealed configuration items contain sensitive information and are ignored for clients without sufficient privilege. <h3>3.10 Configuration Cards</h3> |

A client will only accept a config card if it had sent a corresponding reqconfig card in its request. <p>The content of the configuration item is used to overwrite the corresponding configuration data in the receiver. <h3>3.11 Pragma Cards</h3> <p>The client may try to influence the behavior of the server by issuing a pragma card: <blockquote> <b>pragma</i> <i>name value...</i> </blockquote> <p>The "pragma" card has at least one argument which is the pragma name. The pragma name defines what the pragma does. A pragma might have zero or more "value" arguments depending on the pragma name. <p>New pragma names may be added to the protocol from time to time in order to enhance the capabilities of Fossil. Unknown pragmas are silently ignored, for backwards compatibility. <p>The following are the known pragma names as of 2019-06-30: <ol> <li><p><b>send-private</b> <p>The send-private pragma instructs the server to send all of its private artifacts to the client. The server will only obey this request if the user has the "x" or "Private" privilege. <li><p><b>send-catalog</b> <p>The send-catalog pragma instructs the server to transmit igot cards for every known artifact. This can help the client and server to get back in synchronization after a prior protocol error. The "--verily" option to the [/help?cmd=sync|fossil sync] command causes the send-catalog pragma to be transmitted.</p> <li><p><b>uv-hash</b> <i>HASH</i> <p>The uv-hash pragma is sent from client to server to provoke a synchronization of unversioned content. The <i>HASH</i> is a SHA1 hash of the names, modification times, and individual hashes of all unversioned files on the client. If the unversioned content hash from the client does not match the unversioned content hash on the server, then the server will reply with either a "pragma uv-push-ok" or "pragma uv-pull-only" card followed by one "uvigot" card for each unversioned file currently held on the server. The collection of "uvigot" cards sent in response to a "uv-hash" pragma is called the "unversioned catalog". The client will used the unversioned catalog to figure out which files (if any) need to be synchronized between client and server and send appropriate "uvfile" or "uvgimme" cards on the next HTTP request.</p> <p>If a client sends a uv-hash pragma and does not receive back either a uv-pull-only or uv-push-ok pragma, that means that the content on the server exactly matches the content on the client and no further synchronization is required. <li><p><b>uv-pull-only</b></i> <p>A server sends the uv-pull-only pragma to the client in response to a uv-hash pragma with a mismatched content hash argument. This pragma indicates that there are differences in unversioned content between the client and server but that content can only be transferred from server to client. The server is unwilling to accept content from the client because the client login lacks the "write-unversioned" permission.</p> <li><p><b>uv-push-ok</b></i> <p>A server sends the uv-push-ok pragma to the client in response to a uv-hash pragma with a mismatched content hash argument. This pragma indicates that there are differences in unversioned content between the client and server and that content can only be transferred in either direction. The server is willing to accept content from the client because the client login has the "write-unversioned" permission.</p> <li><p><b>ci-lock</b> <i>CHECKIN-HASH CLIENT-ID</i></p> <p>A client sends the "ci-lock" pragma to the server to indicate that it is about to add a new check-in as a child of the CHECKIN-HASH check-in and on the same branch as CHECKIN-HASH. If some other client has already indicated that it was also trying to commit against CHECKIN-HASH, that indicates that a fork is about to occur, and the server will reply with a "ci-lock-fail" pragma (see below). Check-in locks automatically expire when the check-in actually occurs, or after a timeout (currently 24-hours but subject to change). <li><p><b>ci-lock-fail</b> <i>LOGIN MTIME</i></p> <p>When a server receives two or more "ci-lock" pragma messages for the same check-in but from different clients, the second a subsequent ci-lock will provoke a ci-lock-fail pragma in the reply to let the client know that it if continues with the check-in it will likely generate a fork. The LOGIN and MTIME arguments are intended to provide information to the client to help it generate a more useful error message. </p> <li><p><b>ci-unlock</b> <i>CLIENT-ID</i></p> <p>A client sends the "ci-unlock" pragma to the server after a successful commit. This instructs the server to release any lock on any check-in previously held by that client. The ci-unlock pragma helps to avoid false-positive lock warnings that might arise if a check-in is aborted and then restarted on a branch. </ol> <h3>3.12 Comment Cards</h3> <p>Any card that begins with "#" (ASCII 0x23) is a comment card and is silently ignored.</p> <h3>3.13 Message and Error Cards</h3> <p>If the server discovers anything wrong with a request, it generates an error card in its reply. When the client sees the error card, it displays an error message to the user and aborts the sync operation. An error card looks like this:</p> <blockquote> <b>error</b> <i>error-message</i> </blockquote> <p>The error message is English text that is encoded in order to be a single token. A space (ASCII 0x20) is represented as "\s" (ASCII 0x5C, 0x73). A newline (ASCII 0x0a) is "\n" (ASCII 0x6C, x6E). A backslash (ASCII 0x5C) is represented as two backslashes "\\". Apart from space and newline, no other whitespace characters nor any unprintable characters are allowed in the error message.</p> <p>The server can also send a message card that also prints a message on the client console, but which is not an error: <blockquote> <b>message</b> <i>message-text</i> </blockquote> <p>The message-text uses the same format as an error message. <h3>3.14 Unknown Cards</h3> <p>If either the client or the server sees a card that is not described above, then it generates an error and aborts.</p> <h2>4.0 Phantoms And Clusters</h2> <p>When a repository knows that an artifact exists and knows the ID of that artifact, but it does not know the artifact content, then it stores that artifact as a "phantom". A repository will typically create a phantom when it receives an igot card for an artifact that it does not hold or when it receives a file card that references a delta source that it does not hold. When a server is generating its reply or when a client is generating a new request, it will usually send gimme cards for every phantom that it holds.</p> <p>A cluster is a special artifact that tells of the existence of other artifacts. Any artifact in the repository that follows the syntactic rules of a cluster is considered a cluster.</p> <p>A cluster is line oriented. Each line of a cluster is a card. The cards are separated by the newline ("\n") character. Each card consists of a single character card type, a space, and a single argument. No extra whitespace and no trailing or leading whitespace is allowed. All cards in the cluster must occur in strict lexicographical order.</p> <p>A cluster consists of one or more "M" cards followed by a single "Z" card. Each M card holds an argument which is an artifact ID for an artifact in the repository. The Z card has a single argument which is the lower-case hexadecimal representation of the MD5 checksum of all preceding M cards up to and included the newline character that occurred just before the Z that starts the Z card.</p> <p>Any artifact that does not match the specifications of a cluster exactly is not a cluster. There must be no extra whitespace in |

Only the most recent version of each file (the version with the largest mtime value) is retained. <p>Unversioned files are synchronized using the [/help?cmd=unversioned|fossil unversioned sync] command. <p>A schematic of an unversioned file synchronization is as follows: <ol> <li>The client sends a "pragma uv-hash" card to the server. The argument to the uv-hash pragma is a hash of all filesnames, mtimes, and content hashes for the unversioned files held by the client. <hr> <li>If the unversioned content hash from the client matches the unversioned content hash on the server, then nothing needs to be done and the server no-ops.

You might think of these artifacts as "files", since in many cases the artifacts are exactly that. But other "structural artifacts" are also included in the mix. These structural artifacts define the relationships between artifacts - which files go together to form a particular version of the project, who checked in that version and when, what was the check-in comment, what wiki pages are included with the project, what are the edit histories of each wiki page, what bug reports or tickets are included, who contributed to the evolution of each ticket, and so forth. This low-level file format is called the "global state" of the repository, since this is the information that is synced to peer repositories using push and pull operations. The low-level file format is also called "enduring" since it is intended to last for many years. The details of the low-level, enduring, global file format are [./fileformat.wiki | described separately]. This article is about how Fossil is currently implemented. Instead of dealing with vague abstractions of "enduring file formats" as the [./fileformat.wiki | other document] does, this article provides some detail on how Fossil actually stores information on disk. <h2>2.0 Three Databases</h2> Fossil stores state information in [http://www.sqlite.org/ | SQLite] database files. SQLite keeps an entire relational database, including multiple tables and indices, in a single disk file. The SQLite library allows the database files to be efficiently queried and updated using the industry-standard SQL language. SQLite updates are atomic, so even in the event of a system crashes or power failure the repository content is protected. Fossil uses three separate classes of SQLite databases: <ol> <li>The configuration database <li>Repository databases <li>Checkout databases </ol> The configuration database is a one-per-user database that holds global configuration information used by Fossil. There is one repository database per project. The repository database is the file that people are normally referring to when they say "a Fossil repository". The checkout database is found in the working checkout for a project and contains state information that is unique to that working checkout. Fossil does not always use all three database files. The web interface, for example, typically only uses the repository database. And the [/help/all | fossil settings] command only opens the configuration database when the --global option is used. But other commands use all three databases at once. For example, the [/help/status | fossil status] command will first locate the checkout database, then use the checkout database to find the repository database, then open the configuration database. Whenever multiple databases are used at the same time, they are all opened on the same SQLite database connection using SQLite's [http://www.sqlite.org/lang_attach.html | ATTACH] command. The chart below provides a quick summary of how each of these database files are used by Fossil, with detailed discussion following. <table border="1" width="80%" cellpadding="0" align="center"> <tr> <td width="33%" valign="top"> <h3 align="center">Configuration Database<br>"~/.fossil" or<br> "~/.config/fossil.db"</h3> <ul> <li>Global [/help/settings |settings] <li>List of active repositories used by the [/help/all | all] command </ul> </td> <td width="34%" valign="top"> <h3 align="center">Repository Database<br>"<i>project</i>.fossil"</h3> <ul> <li>[./fileformat.wiki | Global state of the project] encoded using delta-compression <li>Local [/help/settings|settings] <li>Web interface display preferences <li>User credentials and permissions <li>Metadata about the global state to facilitate rapid queries </ul> </td> <td width="33%" valign="top"> <h3 align="center">Checkout Database<br>"_FOSSIL_" or ".fslckout"</h3> <ul> <li>The repository database used by this checkout <li>The version currently checked out <li>Other versions [/help/merge | merged] in but not yet [/help/commit | committed] <li>Changes from the [/help/add | add], [/help/delete | delete], and [/help/rename | rename] commands that have not yet been committed <li>"mtime" values and other information used to efficiently detect local edits <li>The "[/help/stash | stash]" <li>Information needed to "[/help/undo|undo]" or "[/help/redo|redo]" </ul> </td> </tr> </table> <a name='configdb'></a> <h3>2.1 The Configuration Database</h3> The configuration database holds cross-repository preferences and a list of all repositories for a single user. The [/help/settings | fossil settings] command can be used to specify various operating parameters and preferences for Fossil repositories. Settings can apply to a single repository, or they can apply globally to all repositories for a user. If both a global and a repository value exists for a setting, then the repository-specific value takes precedence. All of the settings have reasonable defaults, and so many users will never need to change them. But if changes to settings are desired, the configuration database provides a way to change settings for all repositories with a single command, rather than having to change the setting individually on each repository. The configuration database also maintains a list of repositories. This list is used by the [/help/all | fossil all] command in order to run various operations such as "sync" or "rebuild" on all repositories managed by a user. <a name='configloc'></a> <h4>2.1.1 Location Of The Configuration Database</h4> On Unix systems, the configuration database is named by the following algorithm: <blockquote><table border="0"> <tr><td>1. if environment variable FOSSIL_HOME exists <td> → <td>$FOSSIL_HOME/.fossil <tr><td>2. if file ~/.fossil exists<td> →<td>~/.fossil <tr><td>3. if environment variable XDG_CONFIG_HOME exists <td> →<td>$XDG_CONFIG_HOME/fossil.db <tr><td>4. if the directory ~/.config exists <td> →<td>~/.config/fossil.db <tr><td>5. Otherwise<td> →<td>~/.fossil </table></blockquote> Another way of thinking of this algorithm is the following: * Use "$FOSSIL_HOME/.fossil" if the FOSSIL_HOME variable is defined * Use the XDG-compatible name (usually ~/.config/fossil.db) on XDG systems if the ~/.fossil file does not already exist * Otherwise, use the traditional unix name of "~/.fossil" This algorithm is complex due to the need for historical compatibility. Originally, the database was always just "~/.fossil". Then support for the FOSSIL_HOME environment variable as added. Later, support for the [https://specifications.freedesktop.org/basedir-spec/basedir-spec-latest.html|XDG-compatible configation filenames] was added. Each of these changes needed to continue to support legacy installations. On Windows, the configuration database is the first of the following for which the corresponding environment variables exist: * %FOSSIL_HOME%/_fossil * %LOCALAPPDATA%/_fossil * %APPDATA%/_fossil * %USERPROFILES%/_fossil * %HOMEDRIVE%%HOMEPATH%/_fossil The second case is the one that usually determines the name Note that the FOSSIL_HOME environment variable can always be set to determine the location of the configuration database. Note also that the configuration database file itself is called ".fossil" or "fossil.db" on unix but "_fossil" on windows. The [/help?cmd=info|fossil info] command will show the location of the configuration database on a line that starts with "config-db:". <h3>2.2 Repository Databases</h3> The repository database is the file that is commonly referred to as "the repository". This is because the repository database contains, among other things, the complete revision, ticket, and wiki history for a project. It is customary to name the repository database after then name of the project, with a ".fossil" suffix. For example, the repository database for the self-hosting Fossil repository is called "fossil.fossil" and the repository database for SQLite is called "sqlite.fossil". <h4>2.2.1 Global Project State</h4> The bulk of the repository database (typically 75 to 85%) consists of the artifacts that comprise the [./fileformat.wiki | enduring, global, shared state] of the project. The artifacts are stored as BLOBs, compressed using [http://www.zlib.net/ | zlib compression] and, where applicable, using [./delta_encoder_algorithm.wiki | delta compression]. The combination of zlib and delta compression results in a considerable space savings. For the SQLite project (when this paragraph was last updated on 2020-02-08) the total size of all artifacts is over 7.1 GB but thanks to the combined zlib and delta compression, that content only takes less than 97 MB of space in the repository database, for a compression ratio of about 74:1. The median size of all content BLOBs after delta and zlib compression have been applied is 156 bytes. The median size of BLOBs without compression is 45,312 bytes. Note that the zlib and delta compression is not an inherent part of the Fossil file format; it is just an optimization. The enduring file format for Fossil is the unordered set of artifacts. The compression techniques are just a detail of how the current implementation of Fossil happens to store these artifacts efficiently on disk. All of the original uncompressed and un-delta'd artifacts can be extracted from a Fossil repository database using the [/help/deconstruct | fossil deconstruct] command. Individual artifacts can be extracted using the [/help/artifact | fossil artifact] command. When accessing the repository database using raw SQL and the [/help/sqlite3 | fossil sql] command, the extension function "<tt>content()</tt>" with a single argument which is the SHA1 or SHA3-256 hash of an artifact will return the complete uncompressed content of that artifact. Going the other way, the [/help/reconstruct | fossil reconstruct] command will scan a directory hierarchy and add all files found to a new repository database. The [/help/import | fossil import] command works by reading the input git-fast-export stream and using it to construct corresponding artifacts which are then written into the repository database. <h4>2.2.2 Project Metadata</h4> The global project state information in the repository database is supplemented by computed metadata that makes querying the project state more efficient. Metadata includes information such as the following: * The names for all files found in any check-in. * All check-ins that modify a given file * Parents and children of each check-in. * Potential timeline rows. * The names of all symbolic tags and the check-ins they apply to. * The names of all wiki pages and the artifacts that comprise each wiki page. * Attachments and the wiki pages or tickets they apply to. * Current content of each ticket. * Cross-references between tickets, check-ins, and wiki pages. The metadata is held in various SQL tables in the repository database. The metadata is designed to facilitate queries for the various timelines and reports that Fossil generates. As the functionality of Fossil evolves, the schema for the metadata can and does change. But schema changes do not invalidate the repository. Remember that the metadata contains no new information - only information that has been extracted from the canonical artifacts and saved in a more useful form. Hence, when the metadata schema changes, the prior metadata can be discarded and the entire metadata corpus can be recomputed from the canonical artifacts. That is what the [/help/rebuild | fossil rebuild] command does. <h4>2.2.3 Display And Processing Preferences</h4> The repository database also holds information used to help format the display of web pages and configuration settings that override the global configuration settings for the specific repository. All of this information (and the user credentials and privileges too) is local to each repository database; it is not shared between repositories by [/help/sync | fossil sync]. That is because it is entirely reasonable that two different websites for the same project might have completely different display preferences and user communities. One instance of the project might be a fork of the other, for example, which pulls from the other but never pushes and extends the project in ways that the keepers of the other website disapprove of. Display and processing information includes the following: * The name and description of the project * The CSS file, header, and footer used by all web pages * The project logo image * Fields of tickets that are considered "significant" and which are therefore collected from artifacts and made available for display * Templates for screens to view, edit, and create tickets * Ticket report formats and display preferences * Local values for [/help/settings | settings] that override the global values defined in the per-user configuration database. Though the display and processing preferences do not move between repository instances using [/help/sync | fossil sync], this information can be shared between repositories using the [/help/config | fossil config push] and [/help/config | fossil config pull] commands. The display and processing information is also copied into new repositories when they are created using [/help/clone | fossil clone]. <h4>2.2.4 User Credentials And Privileges</h4> Just because two development teams are collaborating on a project and allow push and/or pull between their repositories does not mean that they trust each other enough to share passwords and access privileges. Hence the names and emails and passwords and privileges of users are considered private information that is kept locally in each repository. Each repository database has a table holding the username, privileges, and login credentials for users authorized to interact with that particular database. In addition, there is a table named "concealed" that maps the SHA1 hash of each users email address back into their true email address. The concealed table allows just the SHA1 hash of email addresses to be stored in tickets, and thus prevents actual email addresses from falling into the hands of spammers who happen to clone the repository. The content of the user and concealed tables can be pushed and pulled using the [/help/config | fossil config push] and [/help/config | fossil config pull] commands with the "user" and "email" as the AREA argument, but only if you have administrative privileges on the remote repository. <h4>2.2.5 Shunned Artifact List</h4> The set of canonical artifacts for a project - the global state for the project - is intended to be an append-only database. In other words, new artifacts can be added but artifacts can never be removed. But it sometimes happens that inappropriate content is mistakenly or maliciously added to a repository. The only way to get rid of the undesired content is to [./shunning.wiki | "shun"] it. The "shun" table in the repository database records the hash values for all shunned artifacts. The shun table can be pushed or pulled using the [/help/config | fossil config] command with the "shun" AREA argument. The shun table is also copied during a [/help/clone | clone]. <a name='localdb'></a> <h3>2.3 Checkout Databases</h3> Fossil allows a single repository to have multiple working checkouts. Each working checkout has a single database in its root directory that records the state of that checkout. The checkout database is named "_FOSSIL_" or ".fslckout". The checkout database records information such as the following: * The name of the repository database file. * The version that is currently checked out. * Files that have been [/help/add | added], [/help/rm | removed], or [/help/mv | renamed] but not yet committed. * The mtime and size of files as they were originally checked out, in order to expedite checking which files have been edited. * Other check-ins that have been [/help/merge | merged] into the working checkout but not yet committed. * Copies of files prior to the most recent undoable operation - needed to implement the [/help/undo | undo] and [/help/redo | redo] commands. * The [/help/stash | stash]. * State information for the [/help/bisect | bisect] command. For Fossil commands that run from within a working checkout, the first thing that happens is that Fossil locates the checkout database. Fossil first looks in the current directory. If not found there, it looks in the parent directory. If not found there, the parent of the parent. And so forth until either the checkout database is found or the search reaches the root of the file system. (In the latter case, Fossil returns an error, of course.) Once the checkout database is located, it is used to locate the repository database. Notice that the checkout database contains a pointer to the repository database but that the repository database has no record of the checkout databases. That means that a working checkout directory tree can be freely renamed or copied or deleted without consequence. But the repository database file, on the other hand, has to stay in the same place with the same name or else the open checkout databases will not be able to find it. A checkout database is created by the [/help/open | fossil open] command. A checkout database is deleted by [/help/close | fossil close]. The fossil close command really isn't needed; one can accomplish the same thing simply by deleting the checkout database. Note that the stash, the undo stack, and the state of the bisect command are all contained within the checkout database. That means that the fossil close command will delete all stash content, the undo stack, and the bisect state. The close command is not undoable. Use it with care. <h2>3.0 See Also</h2> * [./makefile.wiki | The Fossil Build Process] * [./contribute.wiki | How To Contribute Code To Fossil] * [./adding_code.wiki | Adding New Features To Fossil] |

This feature requires the TH1 hooks feature to be enabled at compile-time. Additionally, the "th1-hooks" repository setting must be enabled at runtime in order to successfully make use of this feature. TH1 Hook Related User-Defined Procedures ---------------------------------------- In order to activate TH1 hooks, one or more of the following user-defined procedures should be defined, generally from within the "th1-setup" script (setting) for a repository. The following bullets summarize the available TH1 hooks: * command\_hook -- _Called before execution of a command._ * command\_notify -- _Called after execution of a command._ * webpage\_hook -- _Called before rendering of a web page._ * webpage\_notify -- _Called after rendering of a web page._ TH1 Hook Related Variables for Commands --------------------------------------- * cmd\_name -- _Name of command being executed._ * cmd\_args -- _Current command line arguments._ * cmd\_flags -- _Bitmask of CMDFLAG values for the command being executed._ TH1 Hook Related Variables for Web Pages ---------------------------------------- * web\_name -- _Name of web page being rendered._ * web\_args -- _Current web page arguments._ * web\_flags -- _Bitmask of CMDFLAG values for the web page being rendered._ <a name="cmdReturnCodes"></a>TH1 Hook Related Return Codes for Commands ----------------------------------------------------------------------- * TH\_OK -- _Command will be executed, notification will be executed._ * TH\_ERROR -- _Command will be skipped, notification will be skipped, error message will be emitted._ * TH\_BREAK -- _Command will be skipped, notification will be skipped._ * TH\_RETURN -- _Command will be executed, notification will be skipped._ * TH\_CONTINUE -- _Command will be skipped, notification will be executed._ For commands that are not included in the Fossil binary, allowing their execution will cause the standard "unknown command" error message to be generated, which will typically exit the process. Therefore, adding a new command generally requires using the TH_CONTINUE return code. <a name="webReturnCodes"></a>TH1 Hook Related Return Codes for Web Pages ------------------------------------------------------------------------ * TH\_OK -- _Web page will be rendered, notification will be executed._ * TH\_ERROR -- _Web page will be skipped, notification will be skipped, error message will be emitted._ * TH\_BREAK -- _Web page will be skipped, notification will be skipped._ * TH\_RETURN -- _Web page will be rendered, notification will be skipped._ * TH\_CONTINUE -- _Web page will be skipped, notification will be executed._ For web pages that are not included in the Fossil binary, allowing their rendering will cause the standard "Not Found" error message to be generated, which will cause an HTTP 404 status code to be sent. Therefore, adding a new web page generally requires using the TH_CONTINUE return code. <a name="triggerReturnCodes"></a>Triggering TH1 Return Codes from a Script -------------------------------------------------------------------------- * TH\_OK -- _This is the default return code, nothing special needed._ * TH\_ERROR -- _Use the **error** command._ * TH\_BREAK -- _Use the **break** command._ * TH\_RETURN -- _Use the **return -code 5** command._ * TH\_CONTINUE -- _Use the **continue** command._ <a name="command_hook"></a>TH1 command_hook Procedure ----------------------------------------------------- * command\_hook This user-defined procedure, if present, is called just before the execution of a command.

Origins ------- TH1 began as a minimalist re-implementation of the Tcl scripting language. There was a need to test the SQLite library on Symbian phones, but at that time all of the test cases for SQLite were written in Tcl and Tcl could not be easily compiled on the SymbianOS. So TH1 was developed as a cut-down version of Tcl that would facilitate running the SQLite test scripts on SymbianOS. Fossil was first being designed at about the same time that TH1 was being developed for testing SQLite on SymbianOS. Early prototypes of Fossil were written in pure Tcl. But as the development shifted toward the use of C-code, the need arose to have a Tcl-like scripting language to help with code generation. TH1 was small and light-weight and used minimal resources and seemed ideally suited for the task. The name "TH1" stands "Test Harness 1", since that was its original purpose. Overview -------- TH1 is a string-processing language. All values are strings. Any numerical operations are accomplished by converting from string to numeric, performing the computation, then converting the result back into a string. (This might seem inefficient, but it is faster than people imagine, and numeric computations do not come up very often for the kinds of work that TH1 does, so it has never been a factor.) A TH1 script consist of a sequence of commands. Each command is terminated by the first *unescaped* newline or ";" character. The text of the command (excluding the newline or semicolon terminator) is broken into space-separated tokens. The first token is the command name and subsequent tokens are the arguments. In this sense, TH1 syntax is similar to the familiar command-line shell syntax. A token is any sequence of characters other than whitespace and semicolons. Or, all text without double-quotes is a single token even if it includes whitespace and semicolons. Or, all text within nested {...} pairs is a single token. The nested {...} form of tokens is important because it allows TH1 commands to have an appearance similar to C/C++. It is important to remember, though, that a TH1 script is really just a list of text commands, not a context-free language with a grammar like C/C++. This can be confusing to long-time C/C++ programmers because TH1 does look a lot like C/C++, but the semantics of TH1 are closer to FORTH or Lisp than they are to C. Consider the `if` command in TH1. if {$current eq "dev"} { puts "hello" } else { puts "world" } The example above is a single command. The first token, and the name of the command, is `if`. The second token is `$current eq "dev"` - an expression. (The outer {...} are removed from each token by the command parser.) The third token is the `puts "hello"`, with its whitespace and newlines. The fourth token is `else"` And the fifth and last token is `puts "world"`. The `if` command evaluates its first argument (the second token) as an expression, and if that expression is true, evaluates its second argument (the third token) as a TH1 script. If the expression is false and the third argument is `else`, then the fourth argument is evaluated as a TH1 expression. So, you see, even though the example above spans five lines, it is really just a single command. All of this also explains the emphasis on *unescaped* characters above: the curly braces `{ }` are string quoting characters in Tcl/TH1, not block delimiters as in C. This is how we can have a command that extends over multiple lines. It is also why the `else` keyword must be cuddled up with the closing brace for the `if` clause's scriptlet. The following is invalid Tcl/TH1: if {$current eq "dev"} { puts "hello" } else { puts "world" } If you try to run this under either Tcl or TH1, the interpreter will tell you that there is no `else` command, because with the newline on the third line, you terminated the `if` command. Occasionally in Tcl/TH1 scripts, you may need to use a backslash at the end of a line to allow a command to extend over multiple lines without being considered two separate commands. Here's an example from one of Fossil's test scripts: return [lindex [regexp -line -inline -nocase -- \ {^uuid:\s+([0-9A-F]{40}) } [eval [getFossilCommand \ $repository "" info trunk]]] end] Those backslashes allow the command to wrap nicely within a standard terminal width while telling the interpreter to consider those three lines as a single command. Summary of Core TH1 Commands ---------------------------- The original Tcl language after when TH1 is modeled has a very rich repertoire of commands. TH1, as it is designed to be minimalist and embedded has a greatly reduced command set. The following bullets summarize the commands available in TH1: * array exists VARNAME * array names VARNAME * break * catch SCRIPT ?VARIABLE? * continue * error ?STRING? * expr EXPR * for INIT-SCRIPT TEST-EXPR NEXT-SCRIPT BODY-SCRIPT * if EXPR SCRIPT (elseif EXPR SCRIPT)* ?else SCRIPT? * info commands * info exists VARNAME * info vars * lindex LIST INDEX * list ARG ... * llength LIST * lsearch LIST STRING * proc NAME ARG-LIST BODY-SCRIPT * rename OLD NEW * return ?-code CODE? ?VALUE? * set VARNAME VALUE * string compare STR1 STR2 * string first NEEDLE HAYSTACK ?START-INDEX? * string index STRING INDEX * string is CLASS STRING * string last NEEDLE HAYSTACK ?START-INDEX? * string length STRING * string range STRING FIRST LAST * string repeat STRING COUNT * unset VARNAME * uplevel ?LEVEL? SCRIPT * upvar ?FRAME? OTHERVAR MYVAR ?OTHERVAR MYVAR? All of the above commands work as in the original Tcl. Refer to the <a href="https://www.tcl-lang.org/man/tcl/contents.htm">Tcl documentation</a> for details. Summary of Core TH1 Variables ----------------------------- * tcl\_platform(engine) -- _This will always have the value "TH1"._ * tcl\_platform(platform) -- _This will have the value "windows" or "unix"._ * th\_stack\_trace -- _This will contain error stack information._ TH1 Extended Commands --------------------- There are many new commands added to TH1 and used to access the special features of Fossil. The following is a summary of the extended commands: * anoncap * anycap * artifact * cgiHeaderLine * checkout * combobox * copybtn * date * decorate * dir * enable\_output * encode64 * getParameter * glob\_match * globalState * hascap * hasfeature * html * htmlize * http * httpize * insertCsrf * linecount * markdown * nonce * puts * query * randhex * redirect * regexp * reinitialize * render * repository * searchable * setParameter * setting * stime * styleHeader * styleFooter * styleScript * tclEval * tclExpr * tclInvoke * tclIsSafe * tclMakeSafe * tclReady * trace * unversioned content * unversioned list * utime * verifyCsrf * verifyLogin * wiki Each of the commands above is documented by a block comment above their implementation in the th\_main.c or th\_tcl.c source files. All commands starting with "tcl", with the exception of "tclReady", require the Tcl integration subsystem be included at compile-time. Additionally, the "tcl" repository setting must be enabled at runtime in order to successfully make use of these commands. <a name="anoncap"></a>TH1 anoncap Command ----------------------------------------- * anoncap STRING... Returns true if the anonymous user has all of the capabilities listed in STRING. <a name="anycap"></a>TH1 anycap Command --------------------------------------- * anycap STRING Returns true if the current user user has any one of the capabilities listed in STRING. <a name="artifact"></a>TH1 artifact Command ------------------------------------------- * artifact ID ?FILENAME? Attempts to locate the specified artifact and return its contents. An error is generated if the repository is not open or the artifact cannot be found. <a name="cgiHeaderLine"></a>TH1 cgiHeaderLine Command ----------------------------------------------------- * cgiHeaderLine line Adds the specified line to the CGI header. <a name="checkout"></a>TH1 checkout Command ------------------------------------------- * checkout ?BOOLEAN? Return the fully qualified directory name of the current checkout or an empty string if it is not available. Optionally, it will attempt to find the current checkout, opening the configuration ("user") database and the repository as necessary, if the boolean argument is non-zero. <a name="combobox"></a>TH1 combobox Command ------------------------------------------- * combobox NAME TEXT-LIST NUMLINES Generates and emits an HTML combobox. NAME is both the name of the CGI parameter and the name of a variable that contains the currently selected value. TEXT-LIST is a list of possible values for the combobox. NUMLINES is 1 for a true combobox. If NUMLINES is greater than one then the display is a listbox with the number of lines given. <a name="copybtn"></a>TH1 copybtn Command ----------------------------------------- * copybtn TARGETID FLIPPED TEXT ?COPYLENGTH? Output TEXT with a click-to-copy button next to it. Loads the copybtn.js Javascript module, and generates HTML elements with the following IDs: * TARGETID: The `<span>` wrapper around TEXT. * copy-TARGETID: The `<span>` for the copy button. If the FLIPPED argument is non-zero, the copy button is displayed after TEXT. The optional COPYLENGTH argument defines the length of the substring of TEXT copied to clipboard: * <= 0: No limit (default if the argument is omitted). * >= 3: Truncate TEXT after COPYLENGTH (single-byte) characters. * 1: Use the "hash-digits" setting as the limit. * 2: Use the length appropriate for URLs as the limit (defined at compile-time by `FOSSIL_HASH_DIGITS_URL`, defaults to 16). <a name="date"></a>TH1 date Command ----------------------------------- * date ?-local? Return a strings which is the current time and date. If the -local option is used, the date appears using localtime instead of UTC. <a name="decorate"></a>TH1 decorate Command ------------------------------------------- * decorate STRING Renders STRING as wiki content; however, only links are handled. No other markup is processed. <a name="dir"></a>TH1 dir Command --------------------------------- * dir CHECKIN ?GLOB? ?DETAILS? Returns a list containing all files in CHECKIN. If GLOB is given only the files matching the pattern GLOB within CHECKIN will be returned. If DETAILS is non-zero, the result will be a list-of-lists, with each element containing at least three elements: the file name, the file size (in bytes), and the file last modification time (relative to the time zone configured for the repository). <a name="enable_output"></a>TH1 enable\_output Command ------------------------------------------------------ * enable\_output BOOLEAN Enable or disable sending output when the combobox, copybtn, puts, or wiki commands are used. <a name="encode64"></a>TH1 encode64 Command ------------------------------------------- * encode64 STRING Encode the specified string using Base64 and return the result. <a name="getParameter"></a>TH1 getParameter Command --------------------------------------------------- * getParameter NAME ?DEFAULT?

Additional global state variables may be exposed in the future. <a name="hascap"></a>TH1 hascap Command --------------------------------------- * hascap STRING... Returns true if the current user has all of the capabilities listed in STRING. <a name="hasfeature"></a>TH1 hasfeature Command ----------------------------------------------- * hasfeature STRING Returns true if the binary has the given compile-time feature enabled. The possible features are: 1. **ssl** -- _Support for the HTTPS transport._ 1. **legacyMvRm** -- _Support for legacy mv/rm command behavior._ 1. **execRelPaths** -- _Use relative paths with external diff/gdiff._ 1. **th1Docs** -- _Support for TH1 in embedded documentation._ 1. **th1Hooks** -- _Support for TH1 command and web page hooks._ 1. **tcl** -- _Support for Tcl integration._ 1. **useTclStubs** -- _Tcl stubs enabled in the Tcl headers._ 1. **tclStubs** -- _Uses Tcl stubs (i.e. linking with stubs library)._ 1. **tclPrivateStubs** -- _Uses Tcl private stubs (i.e. header-only)._ 1. **json** -- _Support for the JSON APIs._ 1. **markdown** -- _Support for Markdown documentation format._ 1. **unicodeCmdLine** -- _The command line arguments are Unicode._ 1. **dynamicBuild** -- _Dynamically linked to libraries._ 1. **mman** -- _Uses POSIX memory APIs from "sys/mman.h"._ 1. **see** -- _Uses the SQLite Encryption Extension._ Specifying an unknown feature will return a value of false, it will not raise a script error. <a name="html"></a>TH1 html Command ----------------------------------- * html STRING Outputs the STRING escaped for HTML. <a name="htmlize"></a>TH1 htmlize Command ----------------------------------------- * htmlize STRING Escape all characters of STRING which have special meaning in HTML. Returns the escaped string. <a name="http"></a>TH1 http Command ----------------------------------- * http ?-asynchronous? ?--? url ?payload? Performs an HTTP or HTTPS request for the specified URL. If a payload is present, it will be interpreted as text/plain and the POST method will be used; otherwise, the GET method will be used. Upon success, if the -asynchronous option is used, an empty string is returned as the result; otherwise, the response from the server is returned as the result. Synchronous requests are not currently implemented. <a name="httpize"></a>TH1 httpize Command ----------------------------------------- * httpize STRING Escape all characters of STRING which have special meaning in URI components. Returns the escaped string. <a name="insertCsrf"></a>TH1 insertCsrf Command ----------------------------------------------- * insertCsrf While rendering a form, call this command to add the Anti-CSRF token as a hidden element of the form. <a name="linecount"></a>TH1 linecount Command --------------------------------------------- * linecount STRING MAX MIN Returns one more than the number of \n characters in STRING. But never returns less than MIN or more than MAX. <a name="markdown"></a>TH1 markdown Command ------------------------------------------- * markdown STRING Renders the input string as markdown. The result is a two-element list. The first element contains the body, rendered as HTML. The second element is the text-only title string. <a name="nonce"></a>TH1 nonce Command ------------------------------------- * nonce Returns the value of the cryptographic nonce for the request being processed. <a name="puts"></a>TH1 puts Command ----------------------------------- * puts STRING Outputs the STRING unchanged. <a name="query"></a>TH1 query Command ------------------------------------- * query ?-nocomplain? SQL CODE Runs the SQL query given by the SQL argument. For each row in the result set, run CODE. In SQL, parameters such as $var are filled in using the value of variable "var". Result values are stored in variables with the column name prior to each invocation of CODE. <a name="randhex"></a>TH1 randhex Command ----------------------------------------- * randhex N Returns a string of N*2 random hexadecimal digits with N<50. If N is omitted, use a value of 10. <a name="redirect"></a>TH1 redirect Command ------------------------------------------- * redirect URL ?withMethod? Issues an HTTP redirect to the specified URL and then exits the process. By default, an HTTP status code of 302 is used. If the optional withMethod argument is present and non-zero, an HTTP status code of 307 is used, which should force the user agent to preserve the original method for the request (e.g. GET, POST) instead of (possibly) forcing the user agent to change the method to GET. <a name="regexp"></a>TH1 regexp Command --------------------------------------- * regexp ?-nocase? ?--? exp string Checks the string against the specified regular expression and returns non-zero if it matches. If the regular expression is invalid or cannot be compiled, an error will be generated. <a name="reinitialize"></a>TH1 reinitialize Command --------------------------------------------------- * reinitialize ?FLAGS? Reinitializes the TH1 interpreter using the specified flags. <a name="render"></a>TH1 render Command --------------------------------------- * render STRING Renders the TH1 template and writes the results. <a name="repository"></a>TH1 repository Command ----------------------------------------------- * repository ?BOOLEAN? Returns the fully qualified file name of the open repository or an empty string if one is not currently open. Optionally, it will attempt to open the repository if the boolean argument is non-zero. <a name="searchable"></a>TH1 searchable Command ----------------------------------------------- * searchable STRING... Return true if searching in any of the document classes identified by STRING is enabled for the repository and user has the necessary capabilities to perform the search. The possible document classes are: 1. **c** -- _Check-in comments_ 1. **d** -- _Embedded documentation_ 1. **t** -- _Tickets_ 1. **w** -- _Wiki_ To be clear, only one of the document classes identified by each STRING needs to be searchable in order for that argument to be true. But all arguments must be true for this routine to return true. Hence, to see if ALL document classes are searchable: if {[searchable c d t w]} {...} But to see if ANY document class is searchable: if {[searchable cdtw]} {...} This command is useful for enabling or disabling a "Search" entry on the menu bar. <a name="setParameter"></a>TH1 setParameter Command --------------------------------------------------- * setParameter NAME VALUE Sets the value of the specified query parameter. <a name="setting"></a>TH1 setting Command ----------------------------------------- * setting name Gets and returns the value of the specified setting. <a name="stime"></a>TH1 stime Command ------------------------------------- * stime Returns the number of microseconds of CPU time consumed by the current process in system space. <a name="styleHeader"></a>TH1 styleHeader Command ------------------------------------------------- * styleHeader TITLE Render the configured style header for the selected skin. <a name="styleFooter"></a>TH1 styleFooter Command ------------------------------------------------- * styleFooter Render the configured style footer for the selected skin. <a name="styleScript"></a>TH1 styleScript Command ------------------------------------------------- * styleScript Render the configured JavaScript for the selected skin. <a name="tclEval"></a>TH1 tclEval Command ----------------------------------------- **This command requires the Tcl integration feature.** * tclEval arg ?arg ...?

The Tcl interpreter will be created automatically if it has not been already. <a name="tclExpr"></a>TH1 tclExpr Command ----------------------------------------- **This command requires the Tcl integration feature.** * tclExpr arg ?arg ...? Evaluates the Tcl expression and returns its result verbatim. If a Tcl script error is generated, it will be transformed into a TH1 script error. The Tcl interpreter will be created automatically if it has not been already. <a name="tclInvoke"></a>TH1 tclInvoke Command --------------------------------------------- **This command requires the Tcl integration feature.** * tclInvoke command ?arg ...? Invokes the Tcl command using the supplied arguments. No additional substitutions are performed on the arguments. The Tcl interpreter will be created automatically if it has not been already. <a name="tclIsSafe"></a>TH1 tclIsSafe Command --------------------------------------------- **This command requires the Tcl integration feature.** * tclIsSafe Returns non-zero if the Tcl interpreter is "safe". The Tcl interpreter will be created automatically if it has not been already. <a name="tclMakeSafe"></a>TH1 tclMakeSafe Command ------------------------------------------------- **This command requires the Tcl integration feature.** * tclMakeSafe Forces the Tcl interpreter into "safe" mode by removing all "unsafe" commands and variables. This operation cannot be undone. The Tcl interpreter will remain "safe" until the process terminates. The Tcl interpreter will be created automatically if it has not been already. <a name="tclReady"></a>TH1 tclReady Command ------------------------------------------- * tclReady Returns true if the binary has the Tcl integration feature enabled and it is currently available for use by TH1 scripts. <a name="trace"></a>TH1 trace Command ------------------------------------- * trace STRING Generates a TH1 trace message if TH1 tracing is enabled. <a name="unversioned_content"></a>TH1 unversioned content Command ----------------------------------------------------------------- * unversioned content FILENAME Attempts to locate the specified unversioned file and return its contents. An error is generated if the repository is not open or the unversioned file cannot be found. <a name="unversioned_list"></a>TH1 unversioned list Command ----------------------------------------------------------- * unversioned list Returns a list of the names of all unversioned files held in the local repository. An error is generated if the repository is not open. <a name="utime"></a>TH1 utime Command ------------------------------------- * utime Returns the number of microseconds of CPU time consumed by the current process in user space. <a name="verifyCsrf"></a>TH1 verifyCsrf Command ----------------------------------------------- * verifyCsrf Before using the results of a form, first call this command to verify that this Anti-CSRF token is present and is valid. If the Anti-CSRF token is missing or is incorrect, that indicates a cross-site scripting attack. If the event of an attack is detected, an error message is generated and all further processing is aborted. <a name="verifyLogin"></a>TH1 verifyLogin Command ------------------------------------------------- * verifyLogin Returns non-zero if the specified user name and password represent a valid login for the repository. <a name="wiki"></a>TH1 wiki Command ----------------------------------- * wiki STRING Renders STRING as wiki content. Tcl Integration Commands ------------------------ When the Tcl integration subsystem is enabled, several commands are added to the Tcl interpreter. They are used to allow Tcl scripts access to the Fossil functionality provided via TH1. The following is a summary of the Tcl commands: * th1Eval * th1Expr <a name="th1Eval"></a>Tcl th1Eval Command ----------------------------------------- **This command requires the Tcl integration feature.** * th1Eval arg Evaluates the TH1 script and returns its result verbatim. If a TH1 script error is generated, it will be transformed into a Tcl script error. <a name="th1Expr"></a>Tcl th1Expr Command ----------------------------------------- **This command requires the Tcl integration feature.** * th1Expr arg Evaluates the TH1 expression and returns its result verbatim. If a TH1 script error is generated, it will be transformed into a Tcl script error. |

Fossil is <u>not</u> based on SQLite. The current implementation of Fossil uses SQLite as a local store for the content of the distributed database and as a cache for meta-information about the distributed database that is precomputed for quick and easy presentation. But the use of SQLite in this role is an implementation detail and is not fundamental to the design. Some future version of Fossil might do away with SQLite and substitute a pile-of-files or a key/value database in place of SQLite. (Actually, that is very unlikely to happen since SQLite works amazingly well in its current role, but the point is that omitting SQLite from Fossil is a theoretical possibility.) The underlying database that Fossil implements has nothing to do with SQLite, or SQL, or even relational database theory. The underlying database is very simple: it is an unordered collection of "artifacts". An artifact is a list of bytes - a "file" in the usual manner of thinking. Many artifacts are simply the content of source files that have been checked into the Fossil repository. Call these "content artifacts". Other artifacts, known as "control artifacts", contain ASCII text in a particular format that defines relationships between other artifacts, such as which content artifacts that go together to form a particular version of the project. Each artifact is named by its SHA1 or SHA3-256 hash and is thus immutable. Artifacts can be added to the database but not removed (if we ignore the exceptional case of [./shunning.wiki | shunning].) Repositories synchronize by computing the union of their artifact sets. SQL and relation theory play no role in any of this. SQL enters the picture only in the implementation details. The current implementation of Fossil stores each artifact as a BLOB in an SQLite |

The schema of the local relational database changes from time to time as the Fossil implementation is enhanced, and the content is recomputed from the unchanging bag of artifacts. The local relational database is an implementation detail which currently happens to use SQLite. Another way to think of the relational tables in a Fossil repository is as an index for the artifacts.

That answers the first question. <h2>SQL Is A High-Level Scripting Language</h2> The second concern states that Fossil does not use a high-level scripting language. But that is not true. Fossil uses SQL (as implemented by SQLite) as its scripting language. This misunderstanding likely arises because people fail to appreciate that SQL is a programming language. People are taught that SQL is a "query language" as if that were somehow different from a "programming language". But they really are two different flavors of the same thing. I find that people do better with SQL if they think of SQL as a programming language and each statement of SQL is a separate program. SQL is a peculiar programming language in that one uses SQL to specify <i>what</i> to compute whereas in most other programming languages one specifies <i>how</i> to carry out the computation. This difference means that SQL is an extraordinary high-level programming language, but it is still just a programming language. For certain types of problems, SQL has a huge advantage over other programming languages because it is so high level and because it allows programmers to focus more on the <i>what</i> and less on the <i>how</i> of a computation. In other words, programmers tend to think about problems at a much higher level when using SQL; this can result in better applications. SQL is also very dense. In practice, this often means that a few lines of SQL can often replace hundreds or thousands of lines of procedural code, with a corresponding decrease in programming effort and opportunities to introduce bugs. Fossil happens to be one of those problems for which SQL is well suited. Much of the "heavy lifting" within the Fossil implementation is carried out using SQL statements. It is true that these SQL statements are glued together with C code, but it turns out that C works surprisingly well in that role. Several early prototypes of Fossil were written in a scripting language (TCL). We normally find that TCL programs are shorter than the equivalent C code by a factor of 10 or more. But in the case of Fossil, the use of TCL was actually making the code longer and more difficult to understand. And so in the final design, we switched from TCL to C in order to make the code easier to implement and debug. Without the advantages of having SQLite built in, the design might well have followed a different path. Most reports generated by Fossil involve a complex set of queries against the relational tables of the repository database. These queries are normally implemented in only a few dozen lines of SQL code. But if those queries had been implemented procedurally using a key/value or pile-of-files database, it may have well been the case that a high-level scripting language such as Tcl, Python, or Ruby may have worked out better than C. |

Each ticket change artifact corresponds to a single change to a ticket. The act of creating a ticket is considered a change. Each ticket change artifact contains the following information: <ul> <li>The ID of the ticket that was changed <li>The time stamp for when the change occurred <li>The user who made the change <li>A list of key/value pairs that show what changed in the ticket </ul> To determine the current state of a particular ticket, Fossil orders the change artifacts for that ticket from oldest to most recent, then applies each change in time stamp order. On each change artifact, there are one or more key/value pairs that implement the change. The key corresponds to a field of the ticket that is modified. The value may either replace the earlier value for that key, or the value may be appended to the prior value. <h2>2.0 Ticket Tables</h2> The low-level artifact format for ticket content is tedious and cumbersome to access in real time. To facility reporting and display of tickets, the low-level artifact information is collected and summarized in a pair of SQL tables in each local repository. Display and reporting of tickets is accomplished by querying these two tables. Note that only the low-level ticket change artifacts are synced. The content of the two ticket tables can always be reconstructed from the ticket change artifacts. And, indeed, the reconstruction of the ticket tables from low-level artifacts happens automatically whenever new ticket change artifacts are received by the system. The important point to remember is that display of tickets is accomplished using SQL tables but that recording and syncing of ticket information is accomplished using ticket change artifacts. <h3>2.1 Ticket Table Schema</h3> The two ticket tables are called TICKET and TICKETCHNG. The default schema (as of this writing) for these two tables is shown below: <blockquote><verbatim> CREATE TABLE ticket( -- Do not change any column that begins with tkt_ tkt_id INTEGER PRIMARY KEY, tkt_uuid TEXT UNIQUE, tkt_mtime DATE, tkt_ctime DATE, -- Add as many fields as required below this line type TEXT, status TEXT, subsystem TEXT, priority TEXT, severity TEXT, foundin TEXT, private_contact TEXT, resolution TEXT, title TEXT, comment TEXT ); CREATE TABLE ticketchng( -- Do not change any column that begins with tkt_ tkt_id INTEGER REFERENCES ticket, tkt_rid INTEGER REFERENCES blob, tkt_mtime DATE, -- Add as many fields as required below this line login TEXT, username TEXT, mimetype TEXT, icomment TEXT ); CREATE INDEX ticketchng_idx1 ON ticketchng(tkt_id, tkt_mtime); </verbatim></blockquote> Generally speaking, there is one row in the TICKETCHNG table for each change to each ticket. In other words, there is one row in the TICKETCHNG table for each low-level ticket change artifact. The TICKET table, on the other hand, contains a summary of the current status of each ticket. Fields of the TICKET and TICKETCHNG tables that begin with "tkt_" are used internally by Fossil. The logic inside of Fossil that converts ticket change artifacts into row data for the two ticket tables expects the "tkt_" fields to always be present. All of the other fields of the TICKET and TICKETCHNG tables are "user defined" in the sense that they can be anything the administrator of the system wants them to be. The user-defined fields should correspond to keys in the key/value pairs of the ticket change artifacts. The <b>tkt_id</b> fields of TICKET and TICKETCHNG are an integer key used to uniquely identify the ticket to which the row belongs. These keys are for internal use only and may change when doing a "fossil rebuild". The <b>tkt_uuid</b> field is the unique hexadecimal identifier for the ticket. Ticket identifiers appear to be SHA1 hash strings, but they are not really the hash of any identifiable artifact. They are just random hexadecimal numbers. When creating a new ticket, Fossil uses a (high-quality) pseudo-random number generator to create the ticket number. The ticket numbers are large so that the chance of collision between any two tickets is vanishingly small. The <b>tkt_mtime</b> field of TICKET shows the time (as a Julian day number) of the most recent ticket change artifact for that ticket. The <b>tkt_mtime</b> field of TICKETCHNG shows the timestamp on the ticket change artifact that the TICKETCHNG row refers to. The <b>tkt_ctime</b> field of TICKET is the time of the oldest ticket change artifact for that ticket, thus holding the time that the ticket was created. The <b>tkt_rid</b> field of TICKETCHNG is the integer primary key in the BLOB table of the ticket change artifact that gave rise to the row in the TICKETCHNG table. All the other fields of the TICKET and TICKETCHNG tables are available for customization for individual projects. None of the remaining fields are required, but all of them are needed in order to use the default ticket creating, viewing, and editing scripts. It is recommended that the other fields be retained and that customizations be restricted to adding new fields above and beyond the default. <h3>2.2 Translating Artifacts To Tables</h3> Each row in the TICKETCHNG table corresponds to a single ticket change artifact. The tkt_id field is the integer primary key of the TICKET table entry for the corresponding ticket. The tkt_rid field is the integer primary key for the BLOB table entry that contains the low-level artifact text. The tkt_mtime field is the time stamp on the ticket change artifact, expressed as a Julian day number. If the ticket change artifact contains a key/value pair where the key is "login", then the corresponding value is stored in the login field of the TICKETCHNG table. The same it true for "username", "mimetype", and "icomment" fields. Any time there is a key/value pair in the ticket change artifact and the key corresponds to the name of a field in the TICKETCHNG table, then the value of that key/value pair is stored in the TICKETCHNG table. If the TICKETCHNG table has a field for which there is no corresponding key/value pair in the artifact, then that field of the TICKETCHNG table is NULL. If there are key/value pairs in the artifact that have no corresponding field in the TICKETCHNG table, those key/value pairs are silently ignored. Each row in the TICKET table records the overall status of a ticket. The tkt_id field is a unique integer primary key for the ticket. the tkt_uuid field is the global ticket identifier - a larger random hexadecimal constant. The tkt_mtime and tkt_ctime fields hold the times of the most recent and the oldest ticket change artifacts for this ticket, respectively. To reconstruct the TICKET table, the ticket change artifacts are visited in time stamp order. As each ticket change artifact is visited, its key/value pairs are examined. For any key/value pair in which the key is the same as a field in the TICKET table, the value of that pair either replaces or is appended to the previous value of the corresponding field in the TICKET table. Whether a value is replaced or appended is determined by markings in the ticket change artifact itself. Most fields are usually replaced. (For example, to change the status from "Open" to "Fixed" would involve a key value pair "status/Fixed" with the replace attribute set). The main exception is the "comment" field, which is usually appended with new comment text. Note that the replace-or-append mark on ticket change artifacts is only used by the TICKET table. Since the initial value of all fields in the TICKETCHNG table is NULL, the replace-or-append mark makes no difference there. <h3>2.3 Old-Style versus New-Style Tickets</h3> Older versions of Fossil (before [/timeline?c=2012-11-27T16:26:29 | 2012-11-27]) only supported the TICKET table. In this older style, new comments were added to tickets by using the append-value feature on the comment field. Thus the TICKET.COMMENT field contains the complete text of all user comments already appended together and ready for display. A problem with the old approach is that all comment text had to be in the same format. In other words, the all comment text had to be either plaintext or wiki or HTML. It was not possible for some comments to be in HTML and others to be plaintext. Some site administrators wanted the ability to mix plaintext, wiki, and HTML comments and display each comment according to its chosen format. Hence, Fossil was enhanced to support the "new-style" tickets. The TICKETCHNG table was added to support new-style tickets. In the new style, comment text is stored with the "icomment" (for "Incremental Comment") key and appears separately, and with its on mimetype, in multiple rows of the TICKETCHNG table. It then falls to the TH1 script code on the View Ticket Page to query the TICKETCHNG table and extract and format the various comments in time stamp order. |

HTTPS) to Fossil is to run it behind a web proxy that supports TLS. This document explains how to use the powerful [nginx web server](http://nginx.org/) to do that. This document is an extension of the [Serving via nginx on Debian][nod] document. Please read that first, then come back here to extend its configuration with TLS. [nod]: ./server/debian/nginx.md ## Install Certbot The [nginx-on-Debian document][nod] had you install a few non-default packages to the system, but there’s one more you need for this guide: $ sudo apt install certbot You can extend this guide to other operating systems by following the instructions found via [the front Certbot web page][cb] instead, telling it what OS and web stack you’re using. Chances are good that they’ve got a good guide for you already. # Configuring Let’s Encrypt, the Easy Way If your web serving needs are simple, [Certbot][cb] can configure nginx for you and keep its certificates up to date. Simply follow Certbot’s [nginx on Ubuntu 18.04 LTS guide][cbnu]. We’d recommend one small change: to use the version of Certbot in the Ubuntu package repository rather than download it from the Certbot site. You should be able to use the nginx configuration given in our [Serving via nginx on Debian][nod] guide with little to no change. The main thing to watch out for is that the TCP port number in the nginx configuration needs to match the value you gave when starting Fossil. If you followed that guide’s advice, it will be 9000. Another option is to use [the `fslsrv` script](/file/tools/fslsrv), in which case the TCP port number will be 12345 or higher. # Configuring Let’s Encrypt, the Hard Way If you’re finding that you can’t get certificates to be issued or renewed using the Easy Way instructions, the problem is usually that your nginx configuration is too complicated for Certbot’s `--nginx` plugin to understand. It attempts to rewrite your nginx configuration files on the fly to achieve the renewal, and if it doesn’t put its directives in the right locations, the domain verification can fail. Let’s Encrypt uses the [Automated Certificate Management Environment][acme] protocol (ACME) to determine whether a given client actually has control over the domain(s) for which it wants a certificate minted. Let’s Encrypt will not blithely let you mint certificates for `google.com` and `paypal.com` just because you ask for it! Your author’s configuration, glossed [in the HTTP-only guide][nod], is complicated enough that the current version of Certbot (0.28 at the time of this writing) can’t cope with it. That’s the primary motivation for me to write this guide: I’m addressing the “me†years hence who needs to upgrade to Ubuntu 20.04 or 22.04 LTS and has forgotten all of this stuff. 😉 ## Step 1: Shifting into Manual The first thing to do is to turn off all of the Certbot automation, because it’ll only get in our way. First, disable the Certbot package’s automatic background updater: $ sudo systemctl disable certbot.timer Next, edit `/etc/letsencrypt/renewal/example.com.conf` to disable the nginx plugins. You’re looking for two lines setting the “install†and “auth†plugins to “nginxâ€. You can comment them out or remove them entirely. ## Step 2: Configuring nginx This is a straightforward extension to [the HTTP-only configuration](./server/debian/nginx.md#config): server { server_name .foo.net; include local/tls-common; charset utf-8; access_log /var/log/nginx/foo.net-https-access.log; error_log /var/log/nginx/foo.net-https-error.log; # Bypass Fossil for the static Doxygen docs location /doc/html { root /var/www/foo.net; location ~* \.(html|ico|css|js|gif|jpg|png)$ { expires 7d; add_header Vary Accept-Encoding; access_log off; } } # Redirect everything else to the Fossil instance location / { include scgi_params; scgi_pass 127.0.0.1:12345; scgi_param HTTPS "on"; scgi_param SCRIPT_NAME ""; } } server { server_name .foo.net; root /var/www/foo.net; include local/http-certbot-only; access_log /var/log/nginx/foo.net-http-access.log; error_log /var/log/nginx/foo.net-http-error.log; } One big difference between this and the HTTP-only case is that we need two `server { }` blocks: one for HTTPS service, and one for HTTP-only service. ### HTTP over TLS (HTTPS) Service The first `server { }` block includes this file, `local/tls-common`: listen 443 ssl; ssl_certificate /etc/letsencrypt/live/example.com/fullchain.pem; ssl_certificate_key /etc/letsencrypt/live/example.com/privkey.pem; ssl_dhparam /etc/letsencrypt/ssl-dhparams.pem; ssl_stapling on; ssl_stapling_verify on; ssl_protocols TLSv1 TLSv1.1 TLSv1.2; ssl_ciphers "ECDHE-ECDSA-AES128-GCM-SHA256:ECDHE-ECDSA-AES256-GCM-SHA384:ECDHE-ECDSA-AES128-SHA:ECDHE-ECDSA-AES256-SHA:ECDHE-ECDSA-AES128-SHA256:ECDHE-ECDSA-AES256-SHA384:ECDHE-RSA-AES128-GCM-SHA256:ECDHE-RSA-AES256-GCM-SHA384:ECDHE-RSA-AES128-SHA:ECDHE-RSA-AES256-SHA:ECDHE-RSA-AES128-SHA256:ECDHE-RSA-AES256-SHA384:DHE-RSA-AES128-GCM-SHA256:DHE-RSA-AES256-GCM-SHA384:DHE-RSA-AES128-SHA:DHE-RSA-AES256-SHA:DHE-RSA-AES128-SHA256:DHE-RSA-AES256-SHA256â€; ssl_session_cache shared:le_nginx_SSL:1m; ssl_prefer_server_ciphers on; ssl_session_timeout 1440m; These are the common TLS configuration parameters used by all domains hosted by this server. The first line tells nginx to accept TLS-encrypted HTTP connections on the standard HTTPS port. It is the same as `listen 443; ssl on;` in older versions of nginx. Since all of those domains share a single TLS certificate, we reference the same `example.com/*.pem` files written out by Certbot with the `ssl_certificate*` lines. The `ssl_dhparam` directive isn’t strictly required, but without it, the server becomes vulnerable to the [Logjam attack][lja] because some of the cryptography steps are precomputed, making the attacker’s job much easier. The parameter file this directive references should be generated automatically by the Let’s Encrypt package upon installation, making those parameters unique to your server and thus unguessable. If the file doesn’t exist on your system, you can create it manually, so: $ sudo openssl dhparam -out /etc/letsencrypt/dhparams.pem 2048 Beware, this can take a long time. On a shared Linux host I tried it on running OpenSSL 1.1.0g, it took about 21 seconds, but on a fast, idle iMac running LibreSSL 2.6.5, it took 8 minutes and 4 seconds! The next section is also optional. It enables [OCSP stapling][ocsp], a protocol that improves the speed and security of the TLS connection negotiation. The next section containing the `ssl_protocols` and `ssl_ciphers` lines restricts the TLS implementation to only those protocols and ciphers that are currently believed to be safe and secure. This section is the one most prone to bit-rot: as new attacks on TLS and its associated technologies are discovered, this configuration is likely to need to change. Even if we fully succeed in [keeping this document up-to-date](#evolution), the nature of this guide is to recommend static configurations for your server. You will have to keep an eye on this sort of thing and evolve your local configuration as the world changes around it. Running a TLS certificate checker against your site occasionally is a good idea. The most thorough service I’m aware of is the [Qualys SSL Labs Test][qslt], which gives the site I’m basing this guide on an “A†rating at the time of this writing. The long `ssl_ciphers` line above is based on [their advice][qslc]: the default nginx configuration tells OpenSSL to use whatever ciphersuites it considers “high security,†but some of those have come to be considered “weak†in the time between that judgement and the time of this writing. By explicitly giving the list of ciphersuites we want OpenSSL to use within nginx, we can remove those that become considered weak in the future. <a id=â€hstsâ€></a>There are a few things you can do to get an even better grade, such as to enable [HSTS][hsts], which prevents a particular variety of [man in the middle attack][mitm] where our HTTP-to-HTTPS permanent redirect is intercepted, allowing the attacker to prevent the automatic upgrade of the connection to a secure TLS-encrypted one. I didn’t enable that in the configuration above, because it is something a site administrator should enable only after the configuration is tested and stable, and then only after due consideration. There are ways to lock your users out of your site by jumping to HSTS hastily. When you’re ready, there are [guides you can follow][nest] elsewhere online. ### HTTP-Only Service While we’d prefer not to offer HTTP service at all, we need to do so for two reasons: * The temporary reason is that until we get Let’s Encrypt certificates minted and configured properly, we can’t use HTTPS yet at all. * The ongoing reason is that the Certbot [ACME][acme] HTTP-01 challenge used by the Let’s Encrypt service only runs over HTTP. This is not only because it has to work before HTTPS is first configured, but also because it might need to work after a certificate is accidentally allowed to lapse, to get that server back into a state where it can speak HTTPS safely again. So, from the second `service { }` block, we include this file to set up the minimal HTTP service we require, `local/http-certbot-only`: listen 80; listen [::]:80; # This is expressed as a rewrite rule instead of an "if" because # http://wiki.nginx.org/IfIsEvil #rewrite ^(/.well-known/acme-challenge/.*) $1 break; # Force everything else to HTTPS with a permanent redirect. #return 301 https://$host$request_uri; As written above, this configuration does nothing other than to tell nginx that it’s allowed to serve content via HTTP on port 80 as well. We’ll uncomment the `rewrite` and `return` directives below, when we’re ready to begin testing. Notice that this configuration is very different from that in the [HTTP-only nginx on Debian][nod] guide. Most of that guide’s nginx directives moved up into the TLS `server { }` block, because we eventually want this site to be as close to HTTPS-only as we can get it. ## Step 3: Dry Run We want to first request a dry run, because Let’s Encrypt puts some rather low limits on how often you’re allowed to request an actual certificate. You want to be sure everything’s working before you do that. You’ll run a command something like this: $ sudo certbot certonly --webroot --dry-run \ --webroot-path /var/www/example.com \ -d example.com -d www.example.com \ -d example.net -d www.example.net \ --webroot-path /var/www/foo.net \ -d foo.net -d www.foo.net There are two key options here. First, we’re telling Certbot to use its `--webroot` plugin instead of the automated `--nginx` plugin. With this plugin, Certbot writes the [ACME][acme] HTTP-01 challenge files to the static web document root directory behind each domain. For this example, we’ve got two web roots, one of which holds documents for two different second-level domains (`example.com` and `example.net`) with `www` at the third level being optional. This is a common sort of configuration these days, but you needn’t feel that you must slavishly imitate it; the other web root is for an entirely different domain, also with `www` being optional. Since all of these domains are served by a single nginx instance, we need to give all of this in a single command, because we want to mint a single certificate that authenticates all of these domains. The second key option is `--dry-run`, which tells Certbot not to do anything permanent. We’re just seeing if everything works as expected, at this point. ### Troubleshooting the Dry Run If that didn’t work, try creating a manual test: $ mkdir -p /var/www/example.com/.well-known/acme-challenge $ echo hi > /var/www/example.com/.well-known/acme-challenge/test Then try to pull that file over HTTP — not HTTPS! — as `http://example.com/.well-known/acme-challenge/test`. I’ve found that using Firefox or Safari is better for this sort of thing than Chrome, because Chrome is more aggressive about automatically forwarding URLs to HTTPS even if you requested “`http`â€. In extremis, you can do the test manually: $ telnet foo.net 80 GET /.well-known/acme-challenge/test HTTP/1.1 Host: example.com HTTP/1.1 200 OK Server: nginx/1.14.0 (Ubuntu) Date: Sat, 19 Jan 2019 19:43:58 GMT Content-Type: application/octet-stream Content-Length: 3 Last-Modified: Sat, 19 Jan 2019 18:21:54 GMT Connection: keep-alive ETag: "5c436ac2-4" Accept-Ranges: bytes hi You type the first two lines at the remote system, plus the doubled “Enter†to create the blank line, and you get something back that hopefully looks like the rest of the text above. The key bits you’re looking for here are the “hi†line at the end — the document content you created above — and the “200 OK†response code. If you get a 404 or other error response, you need to look into your web server logs to find out what’s going wrong. Note that it’s important to do this test with HTTP/1.1 when debugging a name-based virtual hosting configuration like this. Unless you test only with the primary domain name alias for the server, this test will fail. Using the example configuration above, you can only use the easier-to-type HTTP/1.0 protocol to test the `foo.net` alias. If you’re still running into trouble, the log file written by Certbot can be helpful. It tells you where it’s writing it early in each run. ## Step 4: Getting Your First Certificate Once the dry run is working, you can drop the `--dry-run` option and re-run the long command above. (The one with all the `--webroot*` flags.) This should now succeed, and it will save all of those flag values to your Let’s Encrypt configuration file, so you don’t need to keep giving them. ## Step 5: Test It Edit the `local/http-certbot-only` file and uncomment the `redirect` and `return` directives, then restart your nginx server and make sure it now forces everything to HTTPS like it should: $ sudo systemctl restart nginx Test ideas: * Visit both Fossil and non-Fossil URLs * Log into the repo, log out, and log back in * Clone via `http`: ensure that it redirects to `https`, and that subsequent `fossil sync` commands go directly to `https` due to the 301 permanent redirect. This forced redirect is why we don’t need the Fossil Admin → Access "Redirect to HTTPS on the Login page" setting to be enabled. Not only is it unnecessary with this HTTPS redirect at the front-end proxy level, it would actually [cause an infinite redirect loop if enabled](./ssl.wiki#rloop). ## Step 6: Re-Point Fossil at Your Repositories As of Fossil 2.9, the permanent HTTP-to-HTTPS redirect we enabled above causes Fossil to remember the new URL automatically the first time it’s redirected to it. All you need to do to switch your syncs to HTTPS is: $ cd ~/path/to/checkout $ fossil sync ## Step 7: Renewing Automatically Now that the configuration is solid, you can renew the LE cert with the `certbot` command from above without the `--dry-run` flag plus a restart of nginx: sudo certbot certonly --webroot \ --webroot-path /var/www/example.com \ -d example.com -d www.example.com \ -d example.net -d www.example.net \ --webroot-path /var/www/foo.net \ -d foo.net -d www.foo.net sudo systemctl restart nginx I put those commands in a script in the `PATH`, then arrange to call that periodically. Let’s Encrypt doesn’t let you renew the certificate very often unless forced, and when forced there’s a maximum renewal counter. Nevertheless, some people recommend running this daily and just letting it fail until the server lets you renew. Others arrange to run it no more often than it’s known to work without complaint. Suit yourself. ----------- <a id=â€evolutionâ€></a> **Document Evolution** Large parts of this article have been rewritten several times now due to shifting technology in the TLS and proxying spheres.

Only the newest version of each unversioned file is retained. Though history is omitted, unversioned content is synced between repositories. In the event of a conflict during a sync, the most recent version of each unversioned file is retained and older versions are discarded. Unversioned files are useful for storing ephemeral content such as builds or frequently changing web pages. The [https://www.fossil-scm.org/fossil/uv/download.html|download] page of the self-hosting Fossil repository is stored as unversioned content, for example. <h2>Accessing Unversioned Files</h2> Unversioned files are <u>not</u> a part of a check-out. Unversioned files are intended to be accessible as web pages using URLs of the form: "http://domain/cgi-script/<b>uv</b>/<i>FILENAME</i>". In other words, the URI method "<b>uv</b>" (short for "unversioned") followed by the name of the unversioned file will retrieve the content of the file. The MIME type is inferred from the filename suffix. The content of unversioned files can also be retrieved using the [/help?cmd=unversioned|fossil unvers cat <i>FILENAME</i>] command. A list of all unversioned files on a server can be seen using the [/help?cmd=/uvlist|/uvlist] URL. ([/uvlist|example]). <h2>Syncing Unversioned Files</h2> Unversioned content is synced between repositories, though not by default. Special commands or command-line options are required. Unversioned content can be synced using the following commands: <blockquote><pre> fossil sync <b>-u</b> fossil clone <b>-u</b> <i>URL local-repo-name</i> fossil unversioned sync </pre></blockquote> The [/help?cmd=sync|fossil sync] and [/help?cmd=clone|fossil clone] commands will synchronize unversioned content if and only if the "-u" (or "--unversioned") command-line option is supplied. The [/help?cmd=unversioned|fossil unversioned sync] command will synchronize the unversioned content without synchronizing anything else. Notice that the "-u" option does not work on [/help?cmd=push|fossil push] or [/help?cmd=pull|fossil pull]. The "-u" option is only available on "sync" and "clone". A rough equivalent of an unversioned pull would be the [/help?cmd=unversioned|fossil unversioned revert] command. The "unversioned revert" command causes the unversioned content on the local repository to overwritten by the unversioned content found on the remote repository. <h2>Implementation Details</h2> <i>(This section outlines the current implementation of unversioned files. This is not an interface spec and hence subject to change.)</i> Unversioned content is stored in the repository in the "unversioned" table: <blockquote><pre> CREATE TABLE unversioned( uvid INTEGER PRIMARY KEY AUTOINCREMENT, -- unique ID for this file name TEXT UNIQUE, -- Name of the file rcvid INTEGER, -- From whence this file was received mtime DATETIME, -- Last change (seconds since 1970) hash TEXT, -- SHA1 hash of uncompressed content sz INTEGER, -- Size of uncompressed content encoding INT, -- 0: plaintext 1: zlib compressed content BLOB -- File content ); </pre></blockquote> If there are no unversioned files in the repository, then the "unversioned" table does not necessarily exist. A simple way to purge all unversioned content from a repository is to run: <blockquote><pre> fossil sql "DROP TABLE unversioned; VACUUM;" </pre></blockquote> No delta compression is performed on unversioned files, since there is no history to delta against. Unversioned content is exchanged between servers as whole, uncompressed files (though the content does get compressed when the overall HTTP message payload is compressed). SHA1 hash exchanges are used to avoid sending content over the wire unnecessarily. See the [./sync.wiki|synchronization protocol documentation] for further information. |

This web interface provides everything you need to run a software development project: * [./bugtheory.wiki | Ticketing and bug tracking] * [./wikitheory.wiki | Wiki] * [./embeddeddoc.wiki | On-line documentation] * [./event.wiki | Technical notes] * [./forum.wiki | Forum] * Timelines * Full text search over all of the above * Status information * Graphs of revision and branching history * File and version lists and differences * Download historical versions as ZIP archives * Historical change data * Add and remove tags on check-ins * Move check-ins between branches * Revise check-in comments * Manage user credentials and access permissions * And so forth... (some [./webpage-ex.md|examples]) You get all of this, and more, for free when you use Fossil. There are no extra programs to install or setup. Everything you need is already pre-configured and built into the self-contained, stand-alone Fossil executable. As an example of how useful this web interface can be, the entire [./index.wiki | Fossil website], including the document you are now reading, is rendered using the Fossil web interface, with no enhancements, and little customization. <blockquote> <b>Key point:</b> <i>The Fossil website is just a running instance of Fossil! </blockquote> Note also that because Fossil is a distributed system, you can run the web interface on your local machine while off network (for example, while on an airplane) including making changes to wiki pages and/or trouble ticket, then synchronize with your co-workers after you reconnect. When you clone a Fossil repository, you don't just get the project source code, you get the entire project management website. <h2>Very Simple Startup</h2> To start using the built-in Fossil web interface on an existing Fossil repository, simply type this: <b>fossil ui existing-repository.fossil</b> Substitute the name of your repository, of course. The "ui" command will start a web server running (it figures out an available TCP port to use on its own) and then automatically launches your web browser to point at that server. If you run the "ui" command from within an open check-out, you can omit the repository name: <b>fossil ui</b> The latter case is a very useful short-cut when you are working on a Fossil project and you want to quickly do some work with the web interface. Notice that Fossil automatically finds an unused TCP port to run the server on and automatically points your web browser to the correct URL. So there is never any fumbling around trying to find an open port or to type arcane strings into your browser URL entry box. The interface just pops right up, ready to run. The Fossil web interface is also very easy to setup and run on a network server, as either a CGI program or from inetd, or as an SCGI server. Details on how to do that are described further below. <h2>Things To Do Using The Web Interface</h2> You can view <b>timelines</b> of changes to the project. The default "Timeline" link on the menu bar takes you to a page that shows the 20 most recent check-ins, wiki page edits, ticket/bug-report changes, |

Any changes you make will automatically merge with changes from your co-workers the next time your repository is synchronized. You can view and edit <b>wiki</b> by following the "Wiki" link on the menu bar. Fossil has its own easy-to-remember [/wiki_rules | markup rules], or if you prefer, it also support [/md_rules | Markdown]. And, as with tickets, all of your edits will automatically merge with those of your co-workers when your repository synchronizes. You can view summary reports of <b>branches</b> in the check-in graph by visiting the "Branches" link on the menu bar. From those pages you can follow hyperlinks to get additional details. These screens allow you to easily keep track of what is going on with separate sub-teams within your project team. The "Files" link on the menu allows you to browse through the <b>file hierarchy</b> of the project and to view complete changes histories on individual files, with hyperlinks to the check-ins that made those changes, and with diffs and annotated diffs between versions. The web interface supports [./embeddeddoc.wiki | embedded documentation]. Embedded documentation is documentation files (usually in wiki format) that are checked into project as part of the source tree. Such files |

To run Fossil as CGI, just put the <b>sample-project.fossil</b> file in a directory where CGI scripts have both read and write permission on the file and the directory that contains the file, then add a CGI script that looks something like this: <verbatim> #!/usr/local/bin/fossil repository: /home/www/sample-project.fossil </verbatim> Adjust the script above so that the paths are correct for your system, of course, and also make sure the Fossil binary is installed on the server. But that is <u>all</u> you have to do. You now have everything you need to host a distributed software development project in less than five minutes using a two-line CGI script. Instructions for setting up an SCGI server are [./scgi.wiki | available separately]. You don't have a CGI- or SCGI-capable web server running on your server machine? Not a problem. The Fossil interface can also be launched via inetd or xinetd. An inetd configuration line sufficient to launch the Fossil web interface looks like this: <verbatim> 80 stream tcp nowait.1000 root /usr/local/bin/fossil \ /usr/local/bin/fossil http /home/www/sample-project.fossil </verbatim> As always, you'll want to adjust the pathnames to whatever is appropriate for your system. The xinetd setup uses a different syntax but follows the same idea. |

Often the project is a software application and the individual files are source code together with makefiles, scripts, and "README.txt" files. Other examples of projects include books or manuals in which each chapter or section is held in a separate file. <ul> <li><p>Projects change and evolve. The whole purpose of version control is to track and manage that evolution. <li><p>Most projects contain many files, but it is possible to have a project consisting of just a single file. <li><p>Fossil requires that all the files for a project must be collected into a single directory hierarchy - a single folder possibly with layers of subfolders. Fossil is not a good choice for managing a project that has files scattered hither and yon all over the disk. In other words, Fossil only works for projects where the files are laid out such that they can be archived into a ZIP file or tarball. </ul> <li><p><b>Repository</b> → (also called "repo") a single file that contains all historical versions of all files in a project. A repo is similar to a ZIP archive in that it is a single file that stores compressed versions of many other files. Files can be extracted from the repo and new files can be added to the repo, just as with a ZIP archive. But a repo has other capabilities above and beyond what a ZIP archive can do. <ul> <li><p>Fossil does not care what you name your repository files, though names ending with ".fossil" are recommended. <li><p>A single project typically has multiple, redundant repositories on separate machines. <li><p>All repositories stay synchronized with one another by exchanging information via HTTP or SSH. <li><p>All repos for a single project redundantly store all information about that project. So if any one repo is lost due to a disk crash, all content is preserved in the surviving repos. <li><p>The usual arrangement is one repository per user. And since most users these days have their own computer, that means one repository per computer. But this is not a requirement. It is ok to have multiple copies of the same repository on the same computer. <li><p>Fossil works fine with just a single copy of the repository. But in that case there is no redundancy. If that one repository file is lost due to a hardware malfunction, then there is no way to recover the project. <li><p>Best practice is to keep all repositories for a user in a single folder. Folders such as "~/Fossils" or "%USERPROFILE%\Fossils" are recommended. Fossil itself does not care where the repositories are stored. Nor does Fossil require repositories to be kept in the same folder. But it is easier to organize your work if all repositories are kept in the same place. </ul> <li><p><b>Check-out</b> → a set of files that have been extracted from a repository and that represent a particular version or snapshot of the project. <ul> <li><p>Check-outs must be on the same computer as the repository from which they are extracted. This is just like with a ZIP archive: one must have the ZIP archive file on the local machine before extracting files from ZIP archive. <li><p>There can be multiple check-outs (in different folders) from the same repository. <li><p>The repository must be on the same computer as the check-out, but the relative locations of the repo and the check-out are arbitrary. The repository may be located inside the folder holding the check-out, but it certainly does not have to be and usually is not. <li><p>A special file exists in every check-out that tells Fossil from which repository the check-out was extracted, and which version of the project the check-out represents. This is the ".fslckout" file on unix systems or the "_FOSSIL_" file on Windows. </ul> <li><p><b>Check-in</b> → another name for a particular version of the project. A check-in is a collection of files inside of a repository that represent a snapshot of the project for an instant in time. Check-ins exist only inside of the repository. This contrasts with a check-out which is a collection of files outside of the repository. <ul> <li><p>Every check-out knows the check-in from which it was derived. But check-outs might have been edited and so might not exactly match their associated check-in. <li><p>Check-ins are immutable. They can never be changed. But check-outs are collections of ordinary files on disk. The files of a check-out can be edited just like any other file. <li><p>A check-in can be thought of as an historical snapshot of a check-out. <li><p>"Check-in", "version", "snapshot", and "revision" are synonyms. <li><p> When used as a noun, the word "commit" is another synonym for "check-in". When used as a verb, the word "commit" means to create a new check-in. </ul> </ul> <li><p><b>Basic Fossil commands</b> <ul> <li><p><b>clone</b> → Make a copy of a repository. The original repository is usually (but not always) on a remote machine and the copy is on the local machine. The copy remembers the network location from which it was copied and (by default) tries to keep itself synchronized with the original. <li><p><b>open</b> → Create a new check-out from a repository on the local machine. <li><p><b>update</b> → Modify an existing check-out so that it is derived from a different version of the same project. <li><p><b>commit</b> → Create a new version (a new check-in) of the project that is a snapshot of the current check-out. <li><p><b>revert</b> → Undo all local edits on a check-out. Make the check-out be an exact copy of its associated check-in. <li><p><b>push</b> → Copy content found in a local repository over to a remote repository. (Fossil usually does this automatically in response to a "commit" and so this command is seldom used, but it is important to understand it.) <li><p><b>pull</b> → Copy new content found in a remote repository into a local repository. A "pull" by itself does not modify any check-out. The "pull" command only moves content between repositories. However, the "update" command will (often) automatically do a "pull" before attempting to update the local check-out. <li><p><b>sync</b> → Do both a "push" and a "pull" at the same time. <li><p><b>add</b> → Add a new file to the local check-out. The file must already be on disk. This command tells Fossil to start tracking and managing the file. This command affects only the local check-out and does not modify any repository. The new file is inserted into the repository at the next "commit" command. <li><p><b>rm/mv</b> → Short for 'remove' and 'move', these commands are like "add" in that they specify pending changes to the structure of the check-out. As with "add", no changes are made to the repository until the next "commit". </ul> <li><p><b>The history of a project is a Directed Acyclic Graph (DAG)</b> <ul> <li><p>Fossil (and other distributed VCSes like Git and Mercurial, but not Subversion) represent the history of a project as a directed acyclic graph (DAG). <ul> <li><p>Each check-in is a node in the graph <li><p>If check-in X is derived from check-in Y then there is an arc in the graph from node X to node Y. <li><p>The older check-in (X) is call the "parent" and the newer check-in (Y) is the "child". The child is derived from the parent. </ul> <li><p>Two users (or the same user working in different check-outs) might commit different changes against the same check-in. This results in one parent node having two or more children. <li><p>Command: <b>merge</b> → combines the work of multiple check-ins into a single check-out. That check-out can then be committed to create a new check-in that has two (or more) parents. <ul> <li><p>Most check-ins have just one parent, and either zero or one child. <li><p>When a check-in has two or more parents, one of those parents is the "primary parent". All the other parent nodes are "secondary" or "merge" parents. Conceptually, the primary parent shows the main line of development. Content from the merge parents is added into the main line. <li><p>The "direct children" of a check-in X are all children that have X as their primary parent. <li><p>A check-in node with no direct children is sometimes called a "leaf". <li><p>The "merge" command changes only the check-out. The "commit" command must be run subsequently to make the merge a permanent part of project. </ul> <li><p>Definition: <b>branch</b> → a sequence of check-ins that are all linked together in the DAG through the primary parent. <ul> <li><p>Branches are often given names which propagate to direct children. The tradition in Fossil is to call the main branch "trunk". In Git, the main branch is usually called "master". <li><p>It is possible to have multiple branches with the same name. Fossil has no problem with this, but it can be confusing to humans, so best practice is to give each branch a unique name. <li><p>The name of a branch can be changed by adding special tags to the first check-in of a branch. The name assigned by this special tag automatically propagates to all direct children. </ul> </ul> <li><p><b>Why version control is important (reprise)</b> <ol type="A"> <li><p>Every check-in and every individual file has a unique name - its SHA1 or SHA3-256 hash. Team members can unambiguously identify any specific version of the overall project or any specific version of an individual file. <li><p>Any historical version of the whole project or of any individual file can be easily recreated at any time and by any team member. <li><p>Accidental changes to files can be detected by recomputing their cryptographic hash. <li><p>Files of unknown origin can be identified using their hash. <li><p>Developers are able to work in parallel, review each others work, and easily merge their changes together. External revisions to the baseline can be easily incorporated into the latest changes. <li><p>Developers can follow experimental lines of development, then revert back to an earlier stable version if the experiment does not work out. Creativity is enhanced by allowing crazy ideas to be investigated without destabilizing the project. <li><p>Developers can work on several independent subprojects, flipping back and forth from one subproject to another at will, and merge patches together or back into the main line of development as they mature. <li><p>Older changes can be easily backed out of recent revisions, for example if bugs are found long after the code was committed. <li><p>Enhancements in a branch can be easily copied into other branches, or into the trunk. <li><p>The complete history of all changes is plainly visible to all team members. Project leaders can easily keep track of what all team members are doing. Check-in comments help everyone to understand and/or remember the reason for each change. <li><p>New team members can be brought up-to-date with all of the historical code, quickly and easily. <li><p>New developers, interns, or inexperienced staff members who still do not understand all the details of the project or who are otherwise prone to making mistakes can be assigned significant subprojects to be carried out in branches without risking main line stability. <li><p>Code is automatically synchronized across all machines. No human effort is wasted copying files from machine to machine. The risk of human errors during file transfer and backup is eliminated. <li><p>A hardware failure results in minimal lost work because all previously committed changes will have been automatically replicated on other machines. <li><p>The complete work history of the project is conveniently archived in a single file, simplifying long-term record keeping. <li><p>A precise historical record is maintained which can be used to support copyright and patent claims or regulatory compliance. </ol> </ol> |

The [/wiki_rules | formatting rules for fossil wiki] are designed to be simple and intuitive. The idea is that wiki provides paragraph breaks, numbered and bulleted lists, and hyperlinking for simple documents together with a safe subset of HTML for more complex formatting tasks. The [/md_rules | Markdown formatting rules] are more complex, but are also more widely known, and are thus provided as an alternative. <h2>Stand-alone Wiki Pages</h2> Each wiki page has its own revision history which is independent of the sequence of check-ins (check-ins). Wiki pages can branch and merge just like check-ins, though as of this writing (2008-07-29) there is no mechanism in the user interface to support branching and merging. The current implementation of the wiki shows the version of the wiki page that has the most recent time stamp. In other words, if two users make unrelated changes to the same wiki page on separate repositories and those repositories are synced, the wiki page will fork. The web interface will display whichever edit was checked in last. The other edit can be found in the history. The file format will support merging the branches back together, but there is no mechanism in the user interface (yet) to perform the merge. Every change to a wiki page is a separate [./fileformat.wiki | control artifact] of type [./fileformat.wiki#wikichng | "Wiki Page"]. <h2>Embedded Documentation</h2> Files in the source tree that use the ".wiki", ".md", or ".markdown" suffixes can be accessed and displayed using special URLs to the fossil server. This allows project documentation to be stored in the source tree and accessed online. (Details are described [./embeddeddoc.wiki | separately].) Some projects prefer to store their documentation in wiki. There is nothing wrong with that. But other projects prefer to keep documentation as part of the source tree, so that it is versioned along with the source tree and so that only developers with check-in privileges can change it. Embedded documentation serves this latter purpose. Both forms of documentation use the exact same markup. Some projects may choose to use both forms of documentation at the same time. Because the same format is used, it is trivial to move a file from wiki to embedded documentation or back again as the project evolves. <h2>Bug-reports and check-in comments and Forum messages</h2> The comments on check-ins and the text in the descriptions of bug reports both use wiki formatting. Exactly the same set of formatting rules apply. There is never a need to learn one formatting language for documentation and a different markup for bugs or for check-in comments. <a name="assocwiki"></a> <h2>Auxiliary notes attached to check-ins or branches</h2> Stand-alone wiki pages with special names "branch/<i>BRANCHNAME</i>" or "checkin/<i>HASH</i>" are associated with the corresponding branch or check-in. The wiki text appears in an "About" section of timelines and info screens. Examples: * [/timeline?r=graph-test-branch] shows the text of the [/wiki?name=branch/graph-test-branch&p|branch/graph-test-branch] wiki page at the top of the timeline * [/info/19c60b7fc9e2] shows the text of the [/wiki?name=checkin/19c60b7fc9e2400e56a6f938bbad0e34ca746ca2eabdecac10945539f1f5e8c6&p|checkin/19c60b7fc9e2...] wiki page in the "About" section. This special wiki pages are very useful for recording historical notes. |
