Difference From trunk To release

2022-07-01
01:44
Experimental fix to make '%!S' in hyperlinks stop truncating things that are not check-in identifiers. This should probably be optimzied by refactoring the surrounding code to avoid calculating the length more than once. ... (Leaf check-in: 7eba14d1 user: mistachkin tags: nonHashFix)
01:31
Update the custom makefile for MinGW. ... (Leaf check-in: eddd6b4a user: mistachkin tags: trunk)
2022-06-30
22:05
Documented a browser incompatibility in the pikchr-centering CSS, for later analysis/hacking. Comment changes only, no CSS. ... (check-in: d32df118 user: stephan tags: trunk)
2022-02-23
17:18
Spelling corrections caught by Debian's automated tools, thanks to Barak A. Pearlmutter. ... (check-in: 9993c43b user: danshearer tags: trunk)
13:22
Version 2.18 ... (check-in: 84f25d7e user: drh tags: trunk, release, version-2.18)
13:09
The --share-links option seems to be causing no end of confusion. So we'll just make it undocumented and perhaps remove it or document it properly later. ... (check-in: 0a91005e user: drh tags: trunk)

  ***********************************************************************

  This is a JS Worker file for use with the pikchr wasm build. It
  loads the pikchr wasm module and offers access to it via the Worker
  message-passing interface.

  Because we can have only a single message handler, as opposed to an
  arbitrary number of discrete event listeners like with DOM elements,
  we have to define a lower-level message API. Messages abstractly
  look like:

  { type: string, data: type-specific value }

  Where 'type' is used for dispatching and 'data' is a
  'type'-dependent value.

  The 'type' values expected by each side of the main/worker
  connection vary. The types are described below but subject to
  change at any time as this experiment evolves.

  Main-to-Worker message types:

  - pikchr: data=pikchr-format text to render or an object:

  {
    pikchr: source code for the pikchr,
    darkMode: boolean true to adjust colors for a dark color scheme,
    cssClass: CSS class name to add to the SVG
  }

  Workers-to-Main types

  - stdout, stderr: indicate stdout/stderr output from the wasm
  layer. The data property is the string of the output, noting
  that the emscripten binding emits these one line at a time. Thus,
  if a C-side puts() emits multiple lines in a single call, the JS
  side will see that as multiple calls. Example:

  {type:'stdout', data: 'Hi, world.'}

  - module: Status text. This is intended to alert the main thread
  about module loading status so that, e.g., the main thread can
  update a progress widget and DTRT when the module is finished
  loading and available for work. Status messages come in the form
  
  {type:'module', data:{
  type:'status',
  data: {text:string|null, step:1-based-integer}
  }

  with an incrementing step value for each subsequent message. When
  the module loading is complete, a message with a text value of
  null is posted.

  - pikchr: 

  {type: 'pikchr',
    data:{
      pikchr: input text,
      result: rendered result (SVG on success, HTML on error),
      isError: bool, true if .result holds an error report,
      flags: integer: flags used to configure the pikchr rendering,
      width: if !isError, width (integer pixels) of the SVG,
      height: if !isError, height (integer pixels) of the SVG
    }
  }

       Intercepts status updates from the emscripting module init

       {
       text: string | null, // null at end of load process
       step: integer // starts at 1, increments 1 per call
       }

       We have no way of knowing in advance how many steps will
       be processed/posted, so creating a "percentage done" view is
       not really practical. One can be approximated by giving it a
       current value of message.step and max value of message.step+1,
       though.

       When work is finished, a message with a text value of null is
       submitted.

       After a message with text==null is posted, the module may later
       post messages about fatal problems, e.g. an exit() being
       triggered, so it is recommended that UI elements for posting
       status messages not be outright removed from the DOM when
       text==null, and that they instead be hidden until/unless
       text!=null.

**
******************************************************************************
**
** This SQLite extension implements SQL functions readfile() and
** writefile(), and eponymous virtual type "fsdir".
**
** WRITEFILE(FILE, DATA [, MODE [, MTIME]]):
**
**   If neither of the optional arguments is present, then this UDF
**   function writes blob DATA to file FILE. If successful, the number
**   of bytes written is returned. If an error occurs, NULL is returned.
**
**   If the first option argument - MODE - is present, then it must
**   be passed an integer value that corresponds to a POSIX mode
**   value (file type + permissions, as returned in the stat.st_mode
**   field by the stat() system call). Three types of files may
**   be written/created:
**
**     regular files:  (mode & 0170000)==0100000
**     symbolic links: (mode & 0170000)==0120000
**     directories:    (mode & 0170000)==0040000
**
**   For a directory, the DATA is ignored. For a symbolic link, it is
**   interpreted as text and used as the target of the link. For a
**   regular file, it is interpreted as a blob and written into the
**   named file. Regardless of the type of file, its permissions are
**   set to (mode & 0777) before returning.
**
**   If the optional MTIME argument is present, then it is interpreted
**   as an integer - the number of seconds since the unix epoch. The
**   modification-time of the target file is set to this value before
**   returning.
**
**   If three or more arguments are passed to this function and an
**   error is encountered, an exception is raised.
**
** READFILE(FILE):
**
**   Read and return the contents of file FILE (type blob) from disk.
**
** FSDIR:
**
**   Used as follows:
**
**     SELECT * FROM fsdir($path [, $dir]);
**
**   Parameter $path is an absolute or relative pathname. If the file that it
**   refers to does not exist, it is an error. If the path refers to a regular
**   file or symbolic link, it returns a single row. Or, if the path refers
**   to a directory, it returns one row for the directory, and one row for each
**   file within the hierarchy rooted at $path.
**
**   Each row has the following columns:
**
**     name:  Path to file or directory (text value).
**     mode:  Value of stat.st_mode for directory entry (an integer).
**     mtime: Value of stat.st_mtime for directory entry (an integer).
**     data:  For a regular file, a blob containing the file data. For a
**            symlink, a text value containing the text of the link. For a
**            directory, NULL.
**
**   If a non-NULL value is specified for the optional $dir parameter and
**   $path is a relative path, then $path is interpreted relative to $dir. 
**   And the paths returned in the "name" column of the table are also 
**   relative to directory $dir.
**
** Notes on building this extension for Windows:
**   Unless linked statically with the SQLite library, a preprocessor
**   symbol, FILEIO_WIN32_DLL, must be #define'd to create a stand-alone
**   DLL form of this extension for WIN32. See its use below for details.

**      ORDER BY 1;
**
** The two query parameters are optional.  $prefix is the text of the
** current word being typed and that is to be completed.  $wholeline is
** the complete input line, used for context.
**
** The raw completion() table might return the same candidate multiple
** times, for example if the same column name is used to two or more
** tables.  And the candidates are returned in an arbitrary order.  Hence,
** the DISTINCT and ORDER BY are recommended.

**
** This file implements a VFS shim that allows an SQLite database to be
** appended onto the end of some other file, such as an executable.
**
** A special record must appear at the end of the file that identifies the
** file as an appended database and provides the offset to the first page
** of the exposed content. (Or, it is the length of the content prefix.)
** For best performance page 1 should be located at a disk page boundary,
** though that is not required.
**
** When opening a database using this VFS, the connection might treat
** the file as an ordinary SQLite database, or it might treat it as a
** database appended onto some other file.  The decision is made by
** applying the following rules in order:
**
**  (1)  An empty file is an ordinary database.
**
**  (2)  If the file ends with the appendvfs trailer string
**       "Start-Of-SQLite3-NNNNNNNN" that file is an appended database.
**
**  (3)  If the file begins with the standard SQLite prefix string
**       "SQLite format 3", that file is an ordinary database.
**
**  (4)  If none of the above apply and the SQLITE_OPEN_CREATE flag is
**       set, then a new database is appended to the already existing file.
**
**  (5)  Otherwise, SQLITE_CANTOPEN is returned.
**
** To avoid unnecessary complications with the PENDING_BYTE, the size of
** the file containing the database is limited to 1GiB. (1073741824 bytes)
** This VFS will not read or write past the 1GiB mark.  This restriction
** might be lifted in future versions.  For now, if you need a larger
** database, then keep it in a separate file.
**
** If the file being opened is a plain database (not an appended one), then
** this shim is a pass-through into the default underlying VFS. (rule 3)

**
**
** "prefix file" -  file onto which the database has been appended.
** "padding"     -  zero or more bytes inserted so that "database"
**                  starts on an APND_ROUNDUP boundary
** "database"    -  The SQLite database file
** "append-mark" -  The 25-byte "Start-Of-SQLite3-NNNNNNNN" that indicates
**                  the offset from the start of prefix-file to the start
**                  of "database".
**
** The size of the database is iMark - iPgOne.
**
** The NNNNNNNN in the "Start-Of-SQLite3-NNNNNNNN" suffix is the value
** of iPgOne stored as a big-ending 64-bit integer.
**
** iMark will be the size of the underlying file minus 25 (APND_MARKSIZE).
** Or, iMark is -1 to indicate that it has not yet been written.

**
******************************************************************************
**
** This SQLite extension implements SQL functions readfile() and
** writefile(), and eponymous virtual type "fsdir".
**
** WRITEFILE(FILE, DATA [, MODE [, MTIME]]):
**
**   If neither of the optional arguments is present, then this UDF
**   function writes blob DATA to file FILE. If successful, the number
**   of bytes written is returned. If an error occurs, NULL is returned.
**
**   If the first option argument - MODE - is present, then it must
**   be passed an integer value that corresponds to a POSIX mode
**   value (file type + permissions, as returned in the stat.st_mode
**   field by the stat() system call). Three types of files may
**   be written/created:
**
**     regular files:  (mode & 0170000)==0100000
**     symbolic links: (mode & 0170000)==0120000
**     directories:    (mode & 0170000)==0040000
**
**   For a directory, the DATA is ignored. For a symbolic link, it is
**   interpreted as text and used as the target of the link. For a
**   regular file, it is interpreted as a blob and written into the
**   named file. Regardless of the type of file, its permissions are
**   set to (mode & 0777) before returning.
**
**   If the optional MTIME argument is present, then it is interpreted
**   as an integer - the number of seconds since the unix epoch. The
**   modification-time of the target file is set to this value before
**   returning.
**
**   If three or more arguments are passed to this function and an
**   error is encountered, an exception is raised.
**
** READFILE(FILE):
**
**   Read and return the contents of file FILE (type blob) from disk.
**
** FSDIR:
**
**   Used as follows:
**
**     SELECT * FROM fsdir($path [, $dir]);
**
**   Parameter $path is an absolute or relative pathname. If the file that it
**   refers to does not exist, it is an error. If the path refers to a regular
**   file or symbolic link, it returns a single row. Or, if the path refers
**   to a directory, it returns one row for the directory, and one row for each
**   file within the hierarchy rooted at $path.
**
**   Each row has the following columns:
**
**     name:  Path to file or directory (text value).
**     mode:  Value of stat.st_mode for directory entry (an integer).
**     mtime: Value of stat.st_mtime for directory entry (an integer).
**     data:  For a regular file, a blob containing the file data. For a
**            symlink, a text value containing the text of the link. For a
**            directory, NULL.
**
**   If a non-NULL value is specified for the optional $dir parameter and
**   $path is a relative path, then $path is interpreted relative to $dir. 
**   And the paths returned in the "name" column of the table are also 
**   relative to directory $dir.
**
** Notes on building this extension for Windows:
**   Unless linked statically with the SQLite library, a preprocessor
**   symbol, FILEIO_WIN32_DLL, must be #define'd to create a stand-alone
**   DLL form of this extension for WIN32. See its use below for details.

** This file implements an eponymous virtual table that returns suggested

**
** Suggested usage:
**
**     SELECT DISTINCT candidate COLLATE nocase
**       FROM completion($prefix,$wholeline)
**      ORDER BY 1;
**
** The two query parameters are optional.  $prefix is the text of the
** current word being typed and that is to be completed.  $wholeline is
** the complete input line, used for context.
**
** The raw completion() table might return the same candidate multiple
** times, for example if the same column name is used to two or more
** tables.  And the candidates are returned in an arbitrary order.  Hence,
** the DISTINCT and ORDER BY are recommended.
**
** This virtual table operates at the speed of human typing, and so there
** is no attempt to make it fast.  Even a slow implementation will be much
** faster than any human can type.

**
** This file implements a VFS shim that allows an SQLite database to be
** appended onto the end of some other file, such as an executable.
**
** A special record must appear at the end of the file that identifies the
** file as an appended database and provides the offset to the first page
** of the exposed content. (Or, it is the length of the content prefix.)
** For best performance page 1 should be located at a disk page boundary,
** though that is not required.
**
** When opening a database using this VFS, the connection might treat
** the file as an ordinary SQLite database, or it might treat it as a
** database appended onto some other file.  The decision is made by
** applying the following rules in order:
**
**  (1)  An empty file is an ordinary database.
**
**  (2)  If the file ends with the appendvfs trailer string
**       "Start-Of-SQLite3-NNNNNNNN" that file is an appended database.
**
**  (3)  If the file begins with the standard SQLite prefix string
**       "SQLite format 3", that file is an ordinary database.
**
**  (4)  If none of the above apply and the SQLITE_OPEN_CREATE flag is
**       set, then a new database is appended to the already existing file.
**
**  (5)  Otherwise, SQLITE_CANTOPEN is returned.
**
** To avoid unnecessary complications with the PENDING_BYTE, the size of
** the file containing the database is limited to 1GiB. (1073741824 bytes)
** This VFS will not read or write past the 1GiB mark.  This restriction
** might be lifted in future versions.  For now, if you need a larger
** database, then keep it in a separate file.
**
** If the file being opened is a plain database (not an appended one), then
** this shim is a pass-through into the default underlying VFS. (rule 3)

/* An open appendvfs file
**
** An instance of this structure describes the appended database file.
** A separate sqlite3_file object is always appended. The appended
** sqlite3_file object (which can be accessed using ORIGFILE()) describes
** the entire file, including the prefix, the database, and the
** append-mark.
**
** The structure of an AppendVFS database is like this:
**
**   +-------------+---------+----------+-------------+
**   | prefix-file | padding | database | append-mark |
**   +-------------+---------+----------+-------------+
**                           ^          ^
**                           |          |
**                         iPgOne      iMark
**
**
** "prefix file" -  file onto which the database has been appended.
** "padding"     -  zero or more bytes inserted so that "database"
**                  starts on an APND_ROUNDUP boundary
** "database"    -  The SQLite database file
** "append-mark" -  The 25-byte "Start-Of-SQLite3-NNNNNNNN" that indicates
**                  the offset from the start of prefix-file to the start
**                  of "database".
**
** The size of the database is iMark - iPgOne.
**
** The NNNNNNNN in the "Start-Of-SQLite3-NNNNNNNN" suffix is the value
** of iPgOne stored as a big-ending 64-bit integer.
**
** iMark will be the size of the underlying file minus 25 (APND_MARKSIZE).
** Or, iMark is -1 to indicate that it has not yet been written.

** An instance of struct TriggerStep is used to store a single SQL statement
** that is a part of a trigger-program.
**

** Instances of struct TriggerStep are stored in a singly linked list (linked
** using the "pNext" member) referenced by the "step_list" member of the
** associated struct Trigger instance. The first element of the linked list is
** the first step of the trigger-program.
**

** The "op" member indicates whether this is a "DELETE", "INSERT", "UPDATE" or
** "SELECT" statement. The meanings of the other members is determined by the
** value of "op" as follows:
**

** (op == TK_INSERT)
** orconf    -> stores the ON CONFLICT algorithm
** pSelect   -> The content to be inserted - either a SELECT statement or
**              a VALUES clause.
** zTarget   -> Dequoted name of the table to insert into.


** pIdList   -> If this is an INSERT INTO ... (<column-names>) VALUES ...

/*
 * An instance of struct TriggerStep is used to store a single SQL statement
 * that is a part of a trigger-program.

 *
 * Instances of struct TriggerStep are stored in a singly linked list (linked
 * using the "pNext" member) referenced by the "step_list" member of the
 * associated struct Trigger instance. The first element of the linked list is
 * the first step of the trigger-program.

 *
 * The "op" member indicates whether this is a "DELETE", "INSERT", "UPDATE" or
 * "SELECT" statement. The meanings of the other members is determined by the
 * value of "op" as follows:

 *
 * (op == TK_INSERT)
 * orconf    -> stores the ON CONFLICT algorithm
 * pSelect   -> If this is an INSERT INTO ... SELECT ... statement, then
 *              this stores a pointer to the SELECT statement. Otherwise NULL.
 * zTarget   -> Dequoted name of the table to insert into.
 * pExprList -> If this is an INSERT INTO ... VALUES ... statement, then
 *              this stores values to be inserted. Otherwise NULL.
 * pIdList   -> If this is an INSERT INTO ... (<column-names>) VALUES ...
 *              statement, then this stores the column-names to be
 *              inserted into.
 *
 * (op == TK_DELETE)
 * zTarget   -> Dequoted name of the table to delete from.
 * pWhere    -> The WHERE clause of the DELETE statement if one is specified.
 *              Otherwise NULL.
 *
 * (op == TK_UPDATE)
 * zTarget   -> Dequoted name of the table to update.
 * pWhere    -> The WHERE clause of the UPDATE statement if one is specified.
 *              Otherwise NULL.
 * pExprList -> A list of the columns to update and the expressions to update
 *              them to. See sqlite3Update() documentation of "pChanges"
 *              argument.
