** Implementation of the xBestIndex method for FTS5 tables. Within the 
** WHERE constraint, it searches for the following:
**
**   1. A MATCH constraint against the table column.
**   2. A MATCH constraint against the "rank" column.
**   3. A MATCH constraint against some other column.
**   4. An == constraint against the rowid column.
**   5. A < or <= constraint against the rowid column.
**   6. A > or >= constraint against the rowid column.
**
** Within the ORDER BY, the following are supported:
**
**   5. ORDER BY rank [ASC|DESC]
**   6. ORDER BY rowid [ASC|DESC]
**
** Information for the xFilter call is passed via both the idxNum and 
** idxStr variables. Specifically, idxNum is a bitmask of the following
** flags used to encode the ORDER BY clause:
**
**     FTS5_BI_ORDER_RANK
**     FTS5_BI_ORDER_ROWID
**     FTS5_BI_ORDER_DESC
**
** idxStr is used to encode data from the WHERE clause. For each argument
** passed to the xFilter method, the following is appended to idxStr:
**
**   Match against table column:            "m"
**   Match against rank column:             "r"
**   Match against other column:            "<column-number>"
**   Equality constraint against the rowid: "="
**   A < or <= against the rowid:           "<"
**   A > or >= against the rowid:           ">"
**
** This function ensures that there is at most one "r" or "=". And that if
** there exists an "=" then there is no "<" or ">".
**
** Costs are assigned as follows:
**
**  a) If an unusable MATCH operator is present in the WHERE clause, the
**     cost is unconditionally set to 1e50 (a really big number).
**
**  a) If a MATCH operator is present, the cost depends on the other

** A single instance of this structure is allocated on the stack by 
** sqlite3WindowCodeStep() and a pointer to it passed to the various helper
** routines. This is to reduce the number of arguments required by each
** helper function.
**
** regArg:
**   Each window function requires an accumulator register (just as an
**   ordinary aggregate function does). This variable is set to the first
**   in an array of accumulator registers - one for each window function
**   in the WindowCodeArg.pMWin list.
**
** eDelete:
**   The window functions implementation sometimes caches the input rows
**   that it processes in a temporary table. If it is not zero, this
**   variable indicates when rows may be removed from the temp table (in
**   order to reduce memory requirements - it would always be safe just
**   to leave them there). Possible values for eDelete are:
**
**      WINDOW_RETURN_ROW:
**        An input row can be discarded after it is returned to the caller.
**
**      WINDOW_AGGINVERSE:
**        An input row can be discarded after the window functions xInverse()
**        callbacks have been invoked in it.
**
**      WINDOW_AGGSTEP:
**        An input row can be discarded after the window functions xStep()
**        callbacks have been invoked in it.
**
** start,current,end
**   Consider a window-frame similar to the following:
**
**     (ORDER BY a, b GROUPS BETWEEN 2 PRECEDING AND 2 FOLLOWING)
**
**   The windows functions implmentation caches the input rows in a temp
**   table, sorted by "a, b" (it actually populates the cache lazily, and
**   aggressively removes rows once they are no longer required, but that's
**   a mere detail). It keeps three cursors open on the temp table. One
**   (current) that points to the next row to return to the query engine
**   once its window function values have been calculated. Another (end)
**   points to the next row to call the xStep() method of each window function
**   on (so that it is 2 groups ahead of current). And a third (start) that
**   points to the next row to call the xInverse() method of each window
**   function on.
**
**   Each cursor (start, current and end) consists of a VDBE cursor
**   (WindowCsrAndReg.csr) and an array of registers (starting at
**   WindowCodeArg.reg) that always contains a copy of the peer values 
**   read from the corresponding cursor.
**
**   Depending on the window-frame in question, all three cursors may not
**   be required. In this case both WindowCodeArg.csr and reg are set to
**   0.

#***********************************************************************
#
# This file implements a program that produces scripts (either shell scripts
# or batch files) to implement a particular test that is part of the SQLite
# release testing procedure. For example, to run veryquick.test with a 
# specified set of -D compiler switches.
#
# A "configuration" is a set of options passed to [./configure] and [make]
# to build the SQLite library in a particular fashion. A "platform" is a
# list of tests; most platforms are named after the hardware/OS platform
# that the tests will be run on as part of the release procedure. Each 
# "test" is a combination of a configuration and a makefile target (e.g.
# "fulltest"). The program may be invoked as follows:
#
set USAGE {
$argv0 platforms
    List available platforms.

$argv0 tests ?-nodebug? PLATFORM
    List tests in a specified platform. If the -nodebug switch is 
    specified, synthetic debug/ndebug configurations are omitted. Each
    test is a combination of a configuration and a makefile target.

$argv0 script ?-msvc? CONFIGURATION TARGET
    Given a configuration and make target, return a bash (or, if -msvc
    is specified, batch) script to execute the test. The first argument
    passed to the script must be a directory containing SQLite source code.

$argv0 configurations
    List available configurations.

#***********************************************************************
# 
# This is a test case from content taken "from the wild".  In this
# particular instance, the query was provided with permission by
# Elan Feingold on 2013-06-27.  His message on the SQLite mailing list
# on that date reads:
#
#------------------------------------------------------------------------------
# > Can you send (1) the schema (2) the query that is giving problems, and (3)
# > the content of the sqlite_stat1 table after you have run ANALYZE?   If you
# > can combine all of the above into a script, that would be great!
# >
# > If you send (1..3) above and you give us written permission to include the
# > query in our test suite, that would be off-the-chain terrific.
#
# Please find items 1..3 in this file: http://www.plexapp.com/elan/sqlite_bug.txt
# 
# You have our permission to include the query in your test suite.
# 
# Thanks for an amazing product.
#-----------------------------------------------------------------------------
#
# This test case merely creates the schema and populates SQLITE_STAT1 and
# SQLITE_STAT3 then runs an EXPLAIN QUERY PLAN to ensure that the right plan
# is discovered.  This test case may need to be adjusted for future revisions
# of the query planner manage to select a better query plan.  The query plan
# shown here is known to be very fast with the original data.
#
# This test should work the same with and without SQLITE_ENABLE_STAT3
