Context

2016-03-07
17:49		Merge the virtual table query planner enhancement, the RTREE cost estimate fix, and the statement journal spill delay enhancement from trunk. (check-in: 17fd8f3c user: drh tags: sessions)
2016-03-04
16:42		Merge recent enhancements from trunk. Default page size is 4096. Writes to statement journals are avoided. (check-in: 456df336 user: drh tags: sessions)
14:43		Defer opening and writing statement journals until the size reaches a threshold (currently 64KiB). (check-in: cb9302cc user: drh tags: trunk)
2016-02-25
19:52		Disable the RESTRICT foreign key action if "PRAGMA defer_foreign_keys" is set. (check-in: 8fea1166 user: dan tags: sessions)

** Code for testing the virtual table xBestIndex method and the query
** planner.
*/


/*
** INSTRUCTIONS
**
** This module exports a single tcl command - [register_tcl_module]. When
** invoked, it registers a special virtual table module with a database
** connection.
**
** The virtual table is currently read-only. And always returns zero rows.
** It is created with a single argument - the name of a Tcl command - as
** follows:
**
**   CREATE VIRTUAL TABLE x1 USING tcl(tcl_command);
**
** The command [tcl_command] is invoked when the table is first created (or
** connected), when the xBestIndex() method is invoked and when the xFilter()
** method is called. When it is created (or connected), it is invoked as
** follows:
**
**   tcl_command xConnect
**
** In this case the return value of the script is passed to the
** sqlite3_declare_vtab() function to create the virtual table schema.
**
** When the xBestIndex() method is called by SQLite, the Tcl command is
** invoked as:
**
**   tcl_command xBestIndex CONSTRAINTS ORDERBY MASK
**
** where CONSTRAINTS is a tcl representation of the aConstraints[] array,
** ORDERBY is a representation of the contents of the aOrderBy[] array and
** MASK is a copy of sqlite3_index_info.colUsed. For example if the virtual
** table is declared as:
**
**   CREATE TABLE x1(a, b, c)
**
** and the query is:
**
**   SELECT * FROM x1 WHERE a=? AND c<? ORDER BY b, c;
**
** then the Tcl command is:
**
**   tcl_command xBestIndex                                  \
**     {{op eq column 0 usable 1} {op lt column 2 usable 1}} \
**     {{column 1 desc 0} {column 2 desc 0}}                 \
**     7
**
** The return value of the script is a list of key-value pairs used to
** populate the output fields of the sqlite3_index_info structure. Possible
** keys and the usage of the accompanying values are:
** 
**   "orderby"          (value of orderByConsumed flag)
**   "cost"             (value of estimatedCost field)
**   "rows"             (value of estimatedRows field)
**   "use"              (index of used constraint in aConstraint[])
**   "omit"             (like "use", but also sets omit flag)
**   "idxnum"           (value of idxNum field)
**   "idxstr"           (value of idxStr field)
**
** Refer to code below for further details.
**
** When SQLite calls the xFilter() method, this module invokes the following
** Tcl script:
**
**   tcl_command xFilter IDXNUM IDXSTR ARGLIST
**
** IDXNUM and IDXSTR are the values of the idxNum and idxStr parameters
** passed to xFilter. ARGLIST is a Tcl list containing each of the arguments
** passed to xFilter in text form.
**
** As with xBestIndex(), the return value of the script is interpreted as a
** list of key-value pairs. There is currently only one key defined - "sql".
** The value must be the full text of an SQL statement that returns the data
** for the current scan. The leftmost column returned by the SELECT is assumed
** to contain the rowid. Other columns must follow, in order from left to
** right.

#!/usr/bin/tclsh
#
# This script is used to quickly test a VSIX (Visual Studio Extension) file
# with Visual Studio 2015 on Windows.
#
# PREREQUISITES
#
# 1. This tool is Windows only.
#
# 2. This tool must be executed with "elevated administrator" privileges.
#
# 3. Tcl 8.4 and later are supported, earlier versions have not been tested.
#
# 4. The "sqlite-UWP-output.vsix" file is assumed to exist in the parent
#    directory of the directory containing this script.  The [optional] first
#    command line argument to this script may be used to specify an alternate
#    file.  However, currently, the file must be compatible with both Visual
#    Studio 2015 and the Universal Windows Platform.
#
# 5. The "VERSION" file is assumed to exist in the parent directory of the
#    directory containing this script.  It must contain a version number that
#    matches the VSIX file being tested.
#
# 6. The temporary directory specified in the TEMP or TMP environment variables
#    must refer to an existing directory writable by the current user.
#
# 7. The VS140COMNTOOLS environment variable must refer to the Visual Studio
#    2015 common tools directory.
#
# USAGE
#
# The first argument to this script is optional.  If specified, it must be the
# name of the VSIX file to test.
#
