#### C Compile and options for use in building executables that 
#    will run on the target platform.  This is usually the same
#    as BCC, unless you are cross-compiling.  This C compiler builds
#    the finished binary for fossil.  The BCC compiler above is used
#    for building intermediate code-generator tools.
#
#TCC = gcc -O6
#TCC = gcc -g -O0 -Wall -fprofile-arcs -ftest-coverage
TCC = gcc -g -Os -Wall

# To add support for HTTPS
TCC += -DFOSSIL_ENABLE_SSL

#### Extra arguments for linking the finished binary.  Fossil needs
#    to link against the Z-Lib compression library.  There are no
#    other dependencies.  We sometimes add the -static option here
#    so that we can build a static executable that will run in a
#    chroot jail.
#
LIB = -lz $(LDFLAGS)

# If using HTTPS:
LIB += -lcrypto -lssl

#### Tcl shell for use in running the fossil testsuite.

TCLSH = tclsh

/*
** COMMAND: ci
** COMMAND: commit
**
** Usage: %fossil commit ?OPTIONS? ?FILE...?
**
** Create a new version containing all of the changes in the current
** checkout.  You will be prompted to enter a check-in comment unless
** the comment has been specified on the command-line using "-m" or a 
** file containing the comment using -M.  The editor defined in the
** "editor" fossil option (see %fossil help set) will be used, or from
** the "VISUAL" or "EDITOR" environment variables (in that order) if
** no editor is set.
**


** All files that have changed will be committed unless some subset of
** files is specified on the command line.
**
** The --branch option followed by a branch name causes the new check-in
** to be placed in the named branch.  The --bgcolor option can be followed
** by a color name (ex:  '#ffc0c0') to specify the background color of
** entries in the new branch when shown in the web timeline interface.
**
** A check-in is not permitted to fork unless the --force or -f
** option appears.  A check-in is not allowed against a closed check-in.
**
** The --private option creates a private check-in that is never synced.
** Children of private check-ins are automatically private.
**
** Options:
**
**    --comment|-m COMMENT-TEXT
**    --message-file|-M COMMENT-FILE
**    --branch NEW-BRANCH-NAME
**    --bgcolor COLOR
**    --nosign

**
**
**    auto-captcha     If enabled, the Login page provides a button to
**                     fill in the captcha password.  Default: on
**
**    auto-shun        If enabled, automatically pull the shunning list
**                     from a server to which the client autosyncs.

**
**    autosync         If enabled, automatically pull prior to commit
**                     or update and automatically push after commit or
**                     tag or branch creation.  If the value is "pullonly"
**                     then only pull operations occur automatically.

**
**    binary-glob      The VALUE is a comma-separated list of GLOB patterns
**                     that should be treated as binary files for merging
**                     purposes.  Example:   *.xml
**
**    clearsign        When enabled, fossil will attempt to sign all commits
**                     with gpg.  When disabled (the default), commits will
**                     be unsigned.
**
**    diff-command     External command to run when performing a diff.
**                     If undefined, the internal text diff will be used.
**
**    dont-push        Prevent this repository from pushing from client to
**                     server.  Useful when setting up a private branch.
**
................................................................................
**                     Example:  *.o,*.obj,*.exe
**
**    localauth        If enabled, require that HTTP connections from
**                     127.0.0.1 be authenticated by password.  If
**                     false, all HTTP requests from localhost have
**                     unrestricted access to the repository.
**




**    mtime-changes    Use file modification times (mtimes) to detect when
**                     files have been modified.  (Default "on".)
**
**    pgp-command      Command used to clear-sign manifests at check-in.
**                     The default is "gpg --clearsign -o ".
**
**    proxy            URL of the HTTP proxy.  If undefined or "off" then
**                     the "http_proxy" environment variable is consulted.
**                     If the http_proxy environment variable is undefined
**                     then a direct HTTP connection is used.





**
**    ssh-command      Command used to talk to a remote machine with
**                     the "ssh://" protocol.
**
**    web-browser      A shell command used to launch your preferred
**                     web browser when given a URL as an argument.
**                     Defaults to "start" on windows, "open" on Mac,

 *  sha1.c

 *
 *  Description:
 *      This file implements the Secure Hashing Algorithm 1 as
 *      defined in FIPS PUB 180-1 published April 17, 1995.
 *

 *      The SHA-1, produces a 160-bit message digest for a given
 *      data stream.  It should take about 2**n steps to find a
 *      message with the same digest as a given message and
 *      2**(n/2) to find any two messages with the same digest,
 *      when n is the digest size in bits.  Therefore, this
 *      algorithm can serve as a means of providing a
 *      "fingerprint" for a message.
 *
 *  Portability Issues:
 *      SHA-1 is defined in terms of 32-bit "words".  This code
 *      uses <stdint.h> (included via "sha1.h" to define 32 and 8
 *      bit unsigned integer types.  If your C compiler does not
 *      support 32 bit unsigned integers, this code is not
 *      appropriate.
 *
 *  Caveats:
 *      SHA-1 is designed to work with messages less than 2^64 bits
 *      long.  Although SHA-1 allows a message digest to be generated
 *      for messages of any number of bits less than 2^64, this
 *      implementation only works with messages with a length that is
 *      a multiple of the size of an 8-bit character.
 *

** COMMAND: ticket
** Usage: %fossil ticket SUBCOMMAND ...
**
** Run various subcommands to control tickets
**
**     %fossil ticket show (REPORTTITLE|REPORTNR) ?TICKETFILTER? ?options?
**
**         options can be:
**           ?-l|--limit LIMITCHAR?
**           ?-q|--quote?
**           ?-R|--repository FILE?
**
**         Run the ticket report, identified by the report format title
**         used in the gui. The data is written as flat file on stdout,
**         using "," as separator. The seperator "," can be changed using
**         the -l or --limit option.
**         If TICKETFILTER is given on the commandline, the query is
**         limited with a new WHERE-condition.
**           example:  Report lists a column # with the uuid
**                     TICKETFILTER may be [#]='uuuuuuuuu'
**           example:  Report only lists rows with status not open
**                     TICKETFILTER: status != 'open'
**         If the option -q|--quote is used, the tickets are encoded by
**         quoting special chars(space -> \\s, tab -> \\t, newline -> \\n,
**         cr -> \\r, formfeed -> \\f, vtab -> \\v, nul -> \\0, \\ -> \\\\).
**         Otherwise, the simplified encoding as on the show report raw
**         page in the gui is used.
**
**         Instead of the report title its possible to use the report
**         number. Using the special report number 0 list all columns,
**         defined in the ticket table.
**
**     %fossil ticket list fields
**
**         list all fields, defined for ticket in the fossil repository
**
**     %fossil ticket list reports
**
**         list all ticket reports, defined in the fossil repository
**
**     %fossil ticket set TICKETUUID FIELD VALUE ?FIELD VALUE .. ? ?-q|--quote?
**     %fossil ticket change TICKETUUID FIELD VALUE ?FIELD VALUE .. ? ?-q|--quote?
**
**         change ticket identified by TICKETUUID and set the value of
**         field FIELD to VALUE. Valid field descriptions are:
**            status, type, severity, priority, resolution,
**            foundin, private_contact, resolution, title or comment
**         Field names given above are the ones, defined in a standard
**         fossil environment. If you have added, deleted columns, you
**         change the all your configured columns.
**         You can use more than one field/value pair on the commandline.
**         Using -q|--quote  enables the special character decoding as
**         in "ticket show". So it's possible, to set multiline text or
**         text with special characters.
**
**     %fossil ticket add FIELD VALUE ?FIELD VALUE .. ? ?-q|--quote?
**
**         like set, but create a new ticket with the given values.
**
** The values in set|add are not validated against the definitions
** given in "Ticket Common Script".
