 ** silly C90 rules prohibit a void* from being cast to a function pointer
 ** and so we have to go through the intermediate pointer to avoid problems
 ** when compiling with -pedantic-errors on GCC.)
 **
 ** The FINDER parameter to this macro is the name of the pointer to the

 **
 ** Most finders simply return a pointer to a fixed sqlite3_io_methods
 ** object.  But the "autolockIoFinder" available on MacOSX does a little

/*
** When the 0x10 bit of PRAGMA optimize is set, any ANALYZE commands
** will be run with an analysis_limit set to the lessor of the value of
** the following macro or to the actual analysis_limit if it is non-zero,
** in order to prevent PRAGMA optimize from running for too long.
**
** The value of 2000 is chosen empirically so that the worst-case run-time
** for PRAGMA optimize does not exceed 100 milliseconds against a variety
** of test databases on a RaspberryPI-4 compiled using -Os and without
** -DSQLITE_DEBUG.  Of course, your mileage may vary.  For the purpose of
** this paragraph, "worst-case" means that ANALYZE ends up being
** run on every table in the database.  The worst case typically only
** happens if PRAGMA optimize is run on a database file for which ANALYZE
** has not been previously run and the 0x10000 flag is included so that
** all tables are analyzed.  The usual case for PRAGMA optimize is that
** no ANALYZE commands will be run at all, or if any ANALYZE happens it
** will be against a single table, so that expected timing for PRAGMA
** optimize on a PI-4 is more like 1 millisecond or less with the 0x10000
** flag or less than 100 microseconds without the 0x10000 flag.
**
** An analysis limit of 2000 is almost always sufficient for the query
** planner to fully characterize an index.  The additional accuracy from
** a larger analysis is not usually helpful.

//	** if the page is overfull. This routine ensures that all cells allocated
//	** to the page and its siblings fit into MemPage.aData[] before returning.
//	**
//	** In the course of balancing the page and its siblings, cells may be
//	** inserted into or removed from the parent page (pParent). Doing so

//	** of the page-size, the aOvflSpace[] buffer is guaranteed to be large

//	** Analyze a term that consists of two or more OR-connected
//	** subterms.  So in:
//	**
//	**     ... WHERE  (a=5) AND (b=7 OR c=9 OR d=13) AND (d=13)
//	**                          ^^^^^^^^^^^^^^^^^^^^
//	**
//	** This routine analyzes terms such as the middle term in the above example.
//	** A WhereOrTerm object is computed and attached to the term under
//	** analysis, regardless of the outcome of the analysis.  Hence:
//	**
//	**     WhereTerm.wtFlags   |=  TERM_ORINFO
//	**     WhereTerm.u.pOrInfo  =  a dynamically allocated WhereOrTerm object
//	**
//	** The term being analyzed must have two or more of OR-connected subterms.
//	** A single subterm might be a set of AND-connected sub-subterms.
//	** Examples of terms under analysis:
//	**
//	**     (A)     t1.x=t2.y OR t1.x=t2.z OR t1.y=15 OR t1.z=t3.a+5
//	**     (B)     x=expr1 OR expr2=x OR x=expr3
//	**     (C)     t1.x=t2.y OR (t1.x=t2.z AND t1.y=15)
//	**     (D)     x=expr1 OR (y>11 AND y<22 AND z LIKE '*hello*')
//	**     (E)     (p.a=1 AND q.b=2 AND r.c=3) OR (p.x=4 AND q.y=5 AND r.z=6)
//	**     (F)     x>A OR (x=A AND y>=B)
//	**
//	** CASE 1:
//	**
//	** If all subterms are of the form T.C=expr for some single column of C and
//	** a single table T (as shown in example B above) then create a new virtual
//	** term that is an equivalent IN expression.  In other words, if the term
//	** being analyzed is:
//	**
//	**      x = expr1  OR  expr2 = x  OR  x = expr3
//	**
//	** then create a new virtual term like this:
//	**
//	**      x IN (expr1,expr2,expr3)
//	**
//	** CASE 2:
//	**
//	** If there are exactly two disjuncts and one side has x>A and the other side
//	** has x=A (for the same x and A) then add a new virtual conjunct term to the
//	** WHERE clause of the form "x>=A".  Example:
//	**
//	**      x>A OR (x=A AND y>B)    adds:    x>=A
//	**
//	** The added conjunct can sometimes be helpful in query planning.
//	**
//	** CASE 3:
//	**
//	** If all subterms are indexable by a single table T, then set
//	**
//	**     WhereTerm.eOperator              =  WO_OR
//	**     WhereTerm.u.pOrInfo->indexable  |=  the cursor number for table T
//	**
//	** A subterm is "indexable" if it is of the form
//	** "T.C <op> <expr>" where C is any column of table T and
//	** <op> is one of "=", "<", "<=", ">", ">=", "IS NULL", or "IN".
//	** A subterm is also indexable if it is an AND of two or more
//	** subsubterms at least one of which is indexable.  Indexable AND
//	** subterms have their eOperator set to WO_AND and they have
//	** u.pAndInfo set to a dynamically allocated WhereAndTerm object.
//	**
//	** From another point of view, "indexable" means that the subterm could
//	** potentially be used with an index if an appropriate index exists.
//	** This analysis does not consider whether or not the index exists; that
//	** is decided elsewhere.  This analysis only looks at whether subterms
//	** appropriate for indexing exist.
//	**
//	** All examples A through E above satisfy case 3.  But if a term
//	** also satisfies case 1 (such as B) we know that the optimizer will
//	** always prefer case 1, so in that case we pretend that case 3 is not
//	** satisfied.
//	**
//	** It might be the case that multiple tables are indexable.  For example,
//	** (E) above is indexable on tables P, Q, and R.
//	**
//	** Terms that satisfy case 3 are candidates for lookup by using
//	** separate indices to find rowids for each subterm and composing
//	** the union of all rowids using a RowSet object.  This is similar
//	** to "bitmap indices" in other database engines.
//	**
//	** OTHERWISE:
//	**
//	** If none of cases 1, 2, or 3 apply, then leave the eOperator set to
//	** zero.  This term is not useful for search.

//	** This function is called when an UPDATE or DELETE operation is being
//	** compiled on table pTab, which is the parent table of foreign-key pFKey.
//	** If the current operation is an UPDATE, then the pChanges parameter is
//	** passed a pointer to the list of columns being modified. If it is a
//	** DELETE, pChanges is passed a NULL pointer.
//	**
//	** It returns a pointer to a Trigger structure containing a trigger
//	** equivalent to the ON UPDATE or ON DELETE action specified by pFKey.
//	** If the action is "NO ACTION" then a NULL pointer is returned (these actions
//	** require no special handling by the triggers sub-system, code for them is
//	** created by fkScanChildren()).
//	**
//	** For example, if pFKey is the foreign key and pTab is table "p" in
//	** the following schema:
//	**
//	**   CREATE TABLE p(pk PRIMARY KEY);
//	**   CREATE TABLE c(ck REFERENCES p ON DELETE CASCADE);
//	**
//	** then the returned trigger structure is equivalent to:
//	**
//	**   CREATE TRIGGER ... DELETE ON p BEGIN
//	**     DELETE FROM c WHERE ck = old.pk;
//	**   END;
//	**
//	** The returned pointer is cached as part of the foreign key object. It
//	** is eventually freed along with the rest of the foreign key object by
//	** sqlite3FkDelete().

//	** This routine attempts to flatten subqueries as a performance optimization.
//	** This routine returns 1 if it makes changes and 0 if no flattening occurs.
//	**
//	** To understand the concept of flattening, consider the following
//	** query:
//	**
//	**     SELECT a FROM (SELECT x+y AS a FROM t1 WHERE z<100) WHERE a>5
//	**
//	** The default way of implementing this query is to execute the
//	** subquery first and store the results in a temporary table, then
//	** run the outer query on that temporary table.  This requires two
//	** passes over the data.  Furthermore, because the temporary table
//	** has no indices, the WHERE clause on the outer query cannot be
//	** optimized.
//	**
//	** This routine attempts to rewrite queries such as the above into
//	** a single flat select, like this:
//	**
//	**     SELECT x+y AS a FROM t1 WHERE z<100 AND a>5
//	**
//	** The code generated for this simplification gives the same result
//	** but only has to scan the data once.  And because indices might
//	** exist on the table t1, a complete scan of the data might be
//	** avoided.
//	**
//	** Flattening is subject to the following constraints:
//	**
//	**  (**)  We no longer attempt to flatten aggregate subqueries. Was:
//	**        The subquery and the outer query cannot both be aggregates.
//	**
//	**  (**)  We no longer attempt to flatten aggregate subqueries. Was:
//	**        (2) If the subquery is an aggregate then
//	**        (2a) the outer query must not be a join and
//	**        (2b) the outer query must not use subqueries
//	**             other than the one FROM-clause subquery that is a candidate
//	**             for flattening.  (This is due to ticket [2f7170d73bf9abf80]
//	**             from 2015-02-09.)
//	**
//	**   (3)  If the subquery is the right operand of a LEFT JOIN then
//	**        (3a) the subquery may not be a join

//	**        (**) Was: "The outer query may not have a GROUP BY." This case
//	**             is now managed correctly
//	**        (3d) the outer query may not be DISTINCT.
//	**        See also (26) for restrictions on RIGHT JOIN.
//	**
//	**   (4)  The subquery can not be DISTINCT.
//	**
//	**  (**)  At one point restrictions (4) and (5) defined a subset of DISTINCT
//	**        sub-queries that were excluded from this optimization. Restriction
//	**        (4) has since been expanded to exclude all DISTINCT subqueries.
//	**
//	**  (**)  We no longer attempt to flatten aggregate subqueries.  Was:
//	**        If the subquery is aggregate, the outer query may not be DISTINCT.
//	**
//	**   (7)  The subquery must have a FROM clause.  TODO:  For subqueries without
//	**        A FROM clause, consider adding a FROM clause with the special
//	**        table sqlite_once that consists of a single row containing a
//	**        single NULL.
//	**
//	**   (8)  If the subquery uses LIMIT then the outer query may not be a join.
//	**
//	**   (9)  If the subquery uses LIMIT then the outer query may not be aggregate.
//	**
//	**  (**)  Restriction (10) was removed from the code on 2005-02-05 but we
//	**        accidentally carried the comment forward until 2014-09-15.  Original
//	**        constraint: "If the subquery is aggregate then the outer query
//	**        may not use LIMIT."
//	**
//	**  (11)  The subquery and the outer query may not both have ORDER BY clauses.
//	**
//	**  (**)  Not implemented.  Subsumed into restriction (3).  Was previously
//	**        a separate restriction deriving from ticket #350.
//	**
//	**  (13)  The subquery and outer query may not both use LIMIT.
//	**
//	**  (14)  The subquery may not use OFFSET.
//	**
//	**  (15)  If the outer query is part of a compound select, then the
//	**        subquery may not use LIMIT.
//	**        (See ticket #2339 and ticket [02a8e81d44]).
//	**
//	**  (16)  If the outer query is aggregate, then the subquery may not
//	**        use ORDER BY.  (Ticket #2942)  This used to not matter
//	**        until we introduced the group_concat() function.
//	**
//	**  (17)  If the subquery is a compound select, then
//	**        (17a) all compound operators must be a UNION ALL, and
//	**        (17b) no terms within the subquery compound may be aggregate
//	**              or DISTINCT, and
//	**        (17c) every term within the subquery compound must have a FROM clause
//	**        (17d) the outer query may not be
//	**              (17d1) aggregate, or
//	**              (17d2) DISTINCT
//	**        (17e) the subquery may not contain window functions, and
//	**        (17f) the subquery must not be the RHS of a LEFT JOIN.
//	**        (17g) either the subquery is the first element of the outer
//	**              query or there are no RIGHT or FULL JOINs in any arm
//	**              of the subquery.  (This is a duplicate of condition (27b).)
//	**        (17h) The corresponding result set expressions in all arms of the
//	**              compound must have the same affinity.
//	**
//	**        The parent and sub-query may contain WHERE clauses. Subject to
//	**        rules (11), (13) and (14), they may also contain ORDER BY,
//	**        LIMIT and OFFSET clauses.  The subquery cannot use any compound
//	**        operator other than UNION ALL because all the other compound
//	**        operators have an implied DISTINCT which is disallowed by
//	**        restriction (4).
//	**
//	**        Also, each component of the sub-query must return the same number
//	**        of result columns. This is actually a requirement for any compound
//	**        SELECT statement, but all the code here does is make sure that no
//	**        such (illegal) sub-query is flattened. The caller will detect the
//	**        syntax error and return a detailed message.
//	**
//	**  (18)  If the sub-query is a compound select, then all terms of the
//	**        ORDER BY clause of the parent must be copies of a term returned
//	**        by the parent query.
//	**
//	**  (19)  If the subquery uses LIMIT then the outer query may not
//	**        have a WHERE clause.
//	**
//	**  (20)  If the sub-query is a compound select, then it must not use
//	**        an ORDER BY clause.  Ticket #3773.  We could relax this constraint
//	**        somewhat by saying that the terms of the ORDER BY clause must
//	**        appear as unmodified result columns in the outer query.  But we
//	**        have other optimizations in mind to deal with that case.
//	**
//	**  (21)  If the subquery uses LIMIT then the outer query may not be
//	**        DISTINCT.  (See ticket [752e1646fc]).
//	**
//	**  (22)  The subquery may not be a recursive CTE.
//	**
//	**  (23)  If the outer query is a recursive CTE, then the sub-query may not be
//	**        a compound query.  This restriction is because transforming the
//	**        parent to a compound query confuses the code that handles
//	**        recursive queries in multiSelect().
//	**
//	**  (**)  We no longer attempt to flatten aggregate subqueries.  Was:
//	**        The subquery may not be an aggregate that uses the built-in min() or
//	**        or max() functions.  (Without this restriction, a query like:
//	**        "SELECT x FROM (SELECT max(y), x FROM t1)" would not necessarily
//	**        return the value X for which Y was maximal.)
//	**
//	**  (25)  If either the subquery or the parent query contains a window
//	**        function in the select list or ORDER BY clause, flattening
//	**        is not attempted.
//	**
//	**  (26)  The subquery may not be the right operand of a RIGHT JOIN.
//	**        See also (3) for restrictions on LEFT JOIN.
//	**
//	**  (27)  The subquery may not contain a FULL or RIGHT JOIN unless it
//	**        is the first element of the parent query.  Two subcases:
//	**        (27a) the subquery is not a compound query.
//	**        (27b) the subquery is a compound query and the RIGHT JOIN occurs
//	**              in any arm of the compound query.  (See also (17g).)
//	**
//	**  (28)  The subquery is not a MATERIALIZED CTE.  (This is handled
//	**        in the caller before ever reaching this routine.)
//	**
//	**
//	** In this routine, the "p" parameter is a pointer to the outer query.
//	** The subquery is p->pSrc->a[iFrom].  isAgg is true if the outer query
//	** uses aggregates.
//	**
//	** If flattening is not attempted, this routine is a no-op and returns 0.
//	** If flattening is attempted this routine returns 1.
//	**
//	** All of the expression analysis must occur on both the outer query and
//	** the subquery before this routine runs.

//	** Implementation of the xBestIndex method for FTS5 tables. Within the

//	**   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:            "M<column-number>"
//	**   LIKE  against other column:            "L<column-number>"
//	**   GLOB  against other column:            "G<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 ">".
//	**
//	** If an unusable MATCH operator is present in the WHERE clause, then
//	** SQLITE_CONSTRAINT is returned.
//	**
//	** Costs are assigned as follows:
//	**
//	**  a) If a MATCH operator is present, the cost depends on the other
//	**     constraints also present. As follows:
//	**
//	**       * No other constraints:         cost=50000.0
//	**       * One rowid range constraint:   cost=37500.0
//	**       * Both rowid range constraints: cost=30000.0
//	**       * An == rowid constraint:       cost=25000.0
//	**
//	**  b) Otherwise, if there is no MATCH:
//	**
//	**       * No other constraints:         cost=3000000.0
//	**       * One rowid range constraints:  cost=2250000.0
//	**       * Both rowid range constraint:  cost=750000.0
//	**       * An == rowid constraint:       cost=25.0
//	**
//	** Costs are not modified by the ORDER BY clause.
//	**
//	** The ratios used in case (a) are based on informal results obtained from
//	** the tool/fts5cost.tcl script. The "MATCH and ==" combination has the
//	** cost set quite high because the query may be a prefix query. Unless
//	** there is a prefix index, prefix queries with rowid constraints are much
//	** more expensive than non-prefix queries with rowid constraints.
//	**
//	** The estimated rows returned is set to the cost/40. For simple queries,
//	** experimental results show that cost/4 might be about right. But for
//	** more complex queries that use multiple terms the number of rows might
//	** be far fewer than this. So we compromise and use cost/40.

//	** The page getter methods each try to acquire a reference to a
//	** page with page number pgno. If the requested reference is
//	** successfully obtained, it is copied to *ppPage and SQLITE_OK returned.
//	**
//	** There are different implementations of the getter method depending
//	** on the current state of the pager.
//	**
//	**     getPageNormal()         --  The normal getter
//	**     getPageError()          --  Used if the pager is in an error state
//	**     getPageMmap()           --  Used if memory-mapped I/O is enabled
//	**
//	** If the requested page is already in the cache, it is returned.
//	** Otherwise, a new page object is allocated and populated with data
//	** read from the database file. In some cases, the pcache module may
//	** choose not to allocate a new page object and may reuse an existing
//	** object with no outstanding references.
//	**
//	** The extra data appended to a page is always initialized to zeros the
//	** first time a page is loaded into memory. If the page requested is
//	** already in the cache when this function is called, then the extra
//	** data is left as it was when the page object was last used.
//	**
//	** If the database image is smaller than the requested page or if
//	** the flags parameter contains the PAGER_GET_NOCONTENT bit and the
//	** requested page is not already stored in the cache, then no
//	** actual disk read occurs. In this case the memory image of the
//	** page is initialized to all zeros.
//	**
//	** If PAGER_GET_NOCONTENT is true, it means that we do not care about
//	** the contents of the page. This occurs in two scenarios:
//	**
//	**   a) When reading a free-list leaf page from the database, and
//	**
//	**   b) When a savepoint is being rolled back and we need to load
//	**      a new page into the cache to be filled with the data read
//	**      from the savepoint journal.
//	**
//	** If PAGER_GET_NOCONTENT is true, then the data returned is zeroed instead
//	** of being read from the database. Additionally, the bits corresponding
//	** to pgno in Pager.pInJournal (bitvec of pages already written to the
//	** journal file) and the PagerSavepoint.pInSavepoint bitvecs of any open
//	** savepoints are set. This means if the page is made writable at any
//	** point in the future, using a call to sqlite3PagerWrite(), its contents
//	** will not be journaled. This saves IO.
//	**
//	** The acquisition might fail for several reasons.  In all cases,
//	** an appropriate error code is returned and *ppPage is set to NULL.
//	**
//	** See also sqlite3PagerLookup().  Both this routine and Lookup() attempt
//	** to find a page in the in-memory cache first.  If the page is not already
//	** in memory, this routine goes to disk to read it in whereas Lookup()
//	** just returns 0.  This routine acquires a read-lock the first time it
//	** has to go to disk, and could also playback an old journal if necessary.
//	** Since Lookup() never goes to disk, it never has to deal with locks
//	** or journal files.

//	** RFC-7396 MergePatch for two JSONB blobs.
//	**
//	** pTarget is the target. pPatch is the patch.  The target is updated
//	** in place.  The patch is read-only.
//	**
//	** The original RFC-7396 algorithm is this:
//	**
//	**   define MergePatch(Target, Patch):
//	**     if Patch is an Object:
//	**       if Target is not an Object:
//	**         Target = {} # Ignore the contents and set it to an empty Object
//	**     for each Name/Value pair in Patch:
//	**         if Value is null:
//	**           if Name exists in Target:
//	**             remove the Name/Value pair from Target
//	**         else:
//	**           Target[Name] = MergePatch(Target[Name], Value)
//	**       return Target
//	**     else:
//	**       return Patch
//	**
//	** Here is an equivalent algorithm restructured to show the actual
//	** implementation:
//	**
//	** 01   define MergePatch(Target, Patch):
//	** 02      if Patch is not an Object:
//	** 03         return Patch
//	** 04      else: // if Patch is an Object
//	** 05         if Target is not an Object:
//	** 06            Target = {}
//	** 07      for each Name/Value pair in Patch:
//	** 08         if Name exists in Target:
//	** 09            if Value is null:
//	** 10               remove the Name/Value pair from Target
//	** 11            else
//	** 12               Target[name] = MergePatch(Target[Name], Value)
//	** 13         else if Value is not NULL:
//	** 14            if Value is not an Object:

//	** 16            else:

//	**
//	** Check the JSON argument to see if it is well-formed.  The FLAGS argument
//	** encodes the various constraints on what is meant by "well-formed":
//	**
//	**     0x01      Canonical RFC-8259 JSON text
//	**     0x02      JSON text with optional JSON-5 extensions
//	**     0x04      Superficially appears to be JSONB
//	**     0x08      Strictly well-formed JSONB
//	**
//	** If the FLAGS argument is omitted, it defaults to 1.  Useful values for
//	** FLAGS include:
//	**
//	**    1          Strict canonical JSON text
//	**    2          JSON text perhaps with JSON-5 extensions
//	**    4          Superficially appears to be JSONB
//	**    5          Canonical JSON text or superficial JSONB
//	**    6          JSON-5 text or superficial JSONB
//	**    8          Strict JSONB
//	**    9          Canonical JSON text or strict JSONB
//	**    10         JSON-5 text or strict JSONB
//	**
//	** Other flag combinations are redundant.  For example, every canonical
//	** JSON text is also well-formed JSON-5 text, so FLAG values 2 and 3
//	** are the same.  Similarly, any input that passes a strict JSONB validation
//	** will also pass the superficial validation so 12 through 15 are the same
//	** as 8 through 11 respectively.
//	**
//	** This routine runs in linear time to validate text and when doing strict
//	** JSONB validation.  Superficial JSONB validation is constant time,
//	** assuming the BLOB is already in memory.  The performance advantage
//	** of superficial JSONB validation is why that option is provided.
//	** Application developers can choose to do fast superficial validation or
//	** slower strict validation, according to their specific needs.
//	**
//	** Only the lower four bits of the FLAGS argument are currently used.
//	** Higher bits are reserved for future expansion.   To facilitate
//	** compatibility, the current implementation raises an error if any bit
//	** in FLAGS is set other than the lower four bits.
//	**
//	** The original circa 2015 implementation of the JSON routines in
//	** SQLite only supported canonical RFC-8259 JSON text and the json_valid()
//	** function only accepted one argument.  That is why the default value
//	** for the FLAGS argument is 1, since FLAGS=1 causes this routine to only
//	** recognize canonical RFC-8259 JSON text as valid.  The extra FLAGS
//	** argument was added when the JSON routines were extended to support
//	** JSON5-like extensions and binary JSONB stored in BLOBs.
//	**
//	** Return Values:
//	**
//	**   *   Raise an error if FLAGS is outside the range of 1 to 15.
//	**   *   Return NULL if the input is NULL
//	**   *   Return 1 if the input is well-formed.
//	**   *   Return 0 if the input is not well-formed.

//	/*
//	** Generate code for a compound SELECT statement using a merge
//	** algorithm.  The compound must have an ORDER BY clause for this
//	** to work.
//	**
//	** We assume a query of the following form:
//	**
//	**      <selectA>  <operator>  <selectB>  ORDER BY <orderbylist>
//	**
//	** <operator> is one of UNION ALL, UNION, EXCEPT, or INTERSECT.  The idea
//	** is to code both <selectA> and <selectB> with the ORDER BY clause as
//	** co-routines.  Then run the co-routines in parallel and merge the results
//	** into the output.  In addition to the two coroutines (called selectA and
//	** selectB) there are 7 subroutines:
//	**
//	**    outA:    Move the output of the selectA coroutine into the output
//	**             of the compound query.
//	**
//	**    outB:    Move the output of the selectB coroutine into the output
//	**             of the compound query.  (Only generated for UNION and
//	**             UNION ALL.  EXCEPT and INTERSECT never output a row that
//	**             appears only in B.)
//	**
//	**    AltB:    Called when there is data from both coroutines and A<B.
//	**
//	**    AeqB:    Called when there is data from both coroutines and A==B.
//	**
//	**    AgtB:    Called when there is data from both coroutines and A>B.
//	**
//	**    EofA:    Called when data is exhausted from selectA.
//	**
//	**    EofB:    Called when data is exhausted from selectB.
//	**
//	** The implementation of the latter five subroutines depend on which
//	** <operator> is used:
//	**
//	**
//	**             UNION ALL         UNION            EXCEPT          INTERSECT
//	**          -------------  -----------------  --------------  -----------------
//	**   AltB:   outA, nextA      outA, nextA       outA, nextA         nextA
//	**
//	**   AeqB:   outA, nextA         nextA             nextA         outA, nextA
//	**
//	**   AgtB:   outB, nextB      outB, nextB          nextB            nextB
//	**
//	**   EofA:   outB, nextB      outB, nextB          halt             halt
//	**
//	**   EofB:   outA, nextA      outA, nextA       outA, nextA         halt
//	**
//	** In the AltB, AeqB, and AgtB subroutines, an EOF on A following nextA
//	** causes an immediate jump to EofA and an EOF on B following nextB causes
//	** an immediate jump to EofB.  Within EofA and EofB, and EOF on entry or
//	** following nextX causes a jump to the end of the select processing.
//	**
//	** Duplicate removal in the UNION, EXCEPT, and INTERSECT cases is handled
//	** within the output subroutine.  The regPrev register set holds the previously
//	** output value.  A comparison is made against this value and the output
//	** is skipped if the next results would be the same as the previous.
//	**
//	** The implementation plan is to implement the two coroutines and seven
//	** subroutines first, then put the control logic at the bottom.  Like this:
//	**
//	**          goto Init
//	**     coA: coroutine for left query (A)
//	**     coB: coroutine for right query (B)
//	**    outA: output one row of A
//	**    outB: output one row of B (UNION and UNION ALL only)
//	**    EofA: ...
//	**    EofB: ...
//	**    AltB: ...
//	**    AeqB: ...
//	**    AgtB: ...
//	**    Init: initialize coroutine registers
//	**          yield coA, on eof goto EofA
//	**          yield coB, on eof goto EofB
//	**    Cmpr: Compare A, B
//	**          Jump AltB, AeqB, AgtB
//	**     End: ...
//	**
//	** We call AltB, AeqB, AgtB, EofA, and EofB "subroutines" but they are not
//	** actually called using Gosub and they do not Return.  EofA and EofB loop
//	** until all data is exhausted then jump to the "end" label.  AltB, AeqB,
//	** and AgtB jump to either Cmpr or to one of EofA or EofB.

//	**  (2)  4 byte big-endian integer which is the number of valid page records
//	**       in the journal.  If this value is 0xffffffff, then compute the
//	**       number of page records from the journal size.
//	**  (3)  4 byte big-endian integer which is the initial value for the
//	**       sanity checksum.
//	**  (4)  4 byte integer which is the number of pages to truncate the
//	**       database to during a rollback.
//	**  (5)  4 byte big-endian integer which is the sector size.  The header
//	**       is this many bytes in size.
//	**  (6)  4 byte big-endian integer which is the page size.
//	**  (7)  zero padding out to the next sector size.
//	**  (8)  Zero or more pages instances, each as follows:
//	**        +  4 byte page number.
//	**        +  pPager->pageSize bytes of data.
//	**        +  4 byte checksum
//	**
//	** When we speak of the journal header, we mean the first 7 items above.
//	** Each entry in the journal is an instance of the 8th item.
//	**
//	** Call the value from the second bullet "nRec".  nRec is the number of
//	** valid page entries in the journal.  In most cases, you can compute the
//	** value of nRec from the size of the journal file.  But if a power
//	** failure occurred while the journal was being written, it could be the
//	** case that the size of the journal file had already been increased but
//	** the extra entries had not yet made it safely to disk.  In such a case,
//	** the value of nRec computed from the file size would be too large.  For
//	** that reason, we always use the nRec value in the header.
//	**
//	** If the nRec value is 0xffffffff it means that nRec should be computed
//	** from the file size.  This value is used when the user selects the
//	** no-sync option for the journal.  A power failure could lead to corruption
//	** in this case.  But for things like temporary table (which will be
//	** deleted when the power is restored) we don't care.
//	**
//	** If the file opened as the journal file is not a well-formed
//	** journal file then all pages up to the first corrupted page are rolled
//	** back (or no pages if the journal header is corrupted). The journal file
//	** is then deleted and SQLITE_OK returned, just as if no corruption had
//	** been encountered.
//	**
//	** If an I/O or malloc() error occurs, the journal-file is not deleted
//	** and an error code is returned.
//	**

//	** that might be a hot journal.  Or, it could be that the journal is

//	** The WHERE-clause constant propagation optimization.
//	**
//	** If the WHERE clause contains terms of the form COLUMN=CONSTANT or
//	** CONSTANT=COLUMN that are top-level AND-connected terms that are not
//	** part of a ON clause from a LEFT JOIN, then throughout the query
//	** replace all other occurrences of COLUMN with CONSTANT.
//	**
//	** For example, the query:
//	**
//	**      SELECT * FROM t1, t2, t3 WHERE t1.a=39 AND t2.b=t1.a AND t3.c=t2.b
//	**
//	** Is transformed into
//	**
//	**      SELECT * FROM t1, t2, t3 WHERE t1.a=39 AND t2.b=39 AND t3.c=39
//	**
//	** Return true if any transformations where made and false if not.
//	**
//	** Implementation note:  Constant propagation is tricky due to affinity
//	** and collating sequence interactions.  Consider this example:
//	**
//	**    CREATE TABLE t1(a INT,b TEXT);
//	**    INSERT INTO t1 VALUES(123,'0123');
//	**    SELECT * FROM t1 WHERE a=123 AND b=a;
//	**    SELECT * FROM t1 WHERE a=123 AND b=123;
//	**
//	** The two SELECT statements above should return different answers.  b=a
//	** is always true because the comparison uses numeric affinity, but b=123
//	** is false because it uses text affinity and '0123' is not the same as '123'.
//	** To work around this, the expression tree is not actually changed from
//	** "b=a" to "b=123" but rather the "a" in "b=a" is tagged with EP_FixedCol
//	** and the "123" value is hung off of the pLeft pointer.  Code generator
//	** routines know to generate the constant "123" instead of looking up the
//	** column value.  Also, to avoid collation problems, this optimization is
//	** only attempted if the "a=123" term uses the default BINARY collation.
//	**
//	** 2021-05-25 forum post 6a06202608: Another troublesome case is...
//	**
//	**    CREATE TABLE t1(x);
//	**    INSERT INTO t1 VALUES(10.0);
//	**    SELECT 1 FROM t1 WHERE x=10 AND x LIKE 10;
//	**
//	** The query should return no rows, because the t1.x value is '10.0' not '10'
//	** and '10.0' is not LIKE '10'.  But if we are not careful, the first WHERE
//	** term "x=10" will cause the second WHERE term to become "10 LIKE 10",
//	** resulting in a false positive.  To avoid this, constant propagation for
//	** columns with BLOB affinity is only allowed if the constant is used with
//	** operators ==, <=, <, >=, >, or IS in a way that will cause the correct
//	** type conversions to occur.  See logic associated with the bHasAffBlob flag
//	** for details.

//	**
//	** For a table btree (used for rowid tables), only the pX.nKey value of
//	** the key is used. The pX.pKey value must be NULL.  The pX.nKey is the
//	** rowid or INTEGER PRIMARY KEY of the row.  The pX.nData,pData,nZero fields
//	** hold the content of the row.
//	**
//	** For an index btree (used for indexes and WITHOUT ROWID tables), the
//	** key is an arbitrary byte sequence stored in pX.pKey,nKey.  The
//	** pX.pData,nData,nZero fields must be zero.
//	**
//	** If the seekResult parameter is non-zero, then a successful call to
//	** sqlite3BtreeIndexMoveto() to seek cursor pCur to (pKey,nKey) has already
//	** been performed.  In other words, if seekResult!=0 then the cursor
//	** is currently pointing to a cell that will be adjacent to the cell

//	** smaller then (pKey,nKey).  If seekResult>0 then pCur points to a cell
//	** that is larger than (pKey,nKey).
//	**
//	** If seekResult==0, that means pCur is pointing at some unknown location.
//	** In that case, this routine must seek the cursor to the correct insertion
//	** point for (pKey,nKey) before doing the insertion.  For index btrees,
//	** if pX->nMem is non-zero, then pX->aMem contains pointers to the unpacked
//	** key values and pX->aMem can be used instead of pX->pKey to avoid having

//	** This function is used by the implementation of the IN (...) operator.
//	** The pX parameter is the expression on the RHS of the IN operator, which
//	** might be either a list of expressions or a subquery.
//	**
//	** The job of this routine is to find or create a b-tree object that can
//	** be used either to test for membership in the RHS set or to iterate through
//	** all members of the RHS set, skipping duplicates.
//	**
//	** A cursor is opened on the b-tree object that is the RHS of the IN operator
//	** and the *piTab parameter is set to the index of that cursor.
//	**
//	** The returned value of this function indicates the b-tree type, as follows:
//	**
//	**   IN_INDEX_ROWID      - The cursor was opened on a database table.
//	**   IN_INDEX_INDEX_ASC  - The cursor was opened on an ascending index.
//	**   IN_INDEX_INDEX_DESC - The cursor was opened on a descending index.
//	**   IN_INDEX_EPH        - The cursor was opened on a specially created and
//	**                         populated ephemeral table.
//	**   IN_INDEX_NOOP       - No cursor was allocated.  The IN operator must be
//	**                         implemented as a sequence of comparisons.
//	**
//	** An existing b-tree might be used if the RHS expression pX is a simple
//	** subquery such as:
//	**
//	**     SELECT <column1>, <column2>... FROM <table>
//	**
//	** If the RHS of the IN operator is a list or a more complex subquery, then
//	** an ephemeral table might need to be generated from the RHS and then
//	** pX->iTable made to point to the ephemeral table instead of an
//	** existing table.  In this case, the creation and initialization of the
//	** ephemeral table might be put inside of a subroutine, the EP_Subrtn flag
//	** will be set on pX and the pX->y.sub fields will be set to show where
//	** the subroutine is coded.
//	**
//	** The inFlags parameter must contain, at a minimum, one of the bits
//	** IN_INDEX_MEMBERSHIP or IN_INDEX_LOOP but not both.  If inFlags contains
//	** IN_INDEX_MEMBERSHIP, then the generated table will be used for a fast
//	** membership test.  When the IN_INDEX_LOOP bit is set, the IN index will
//	** be used to loop over all values of the RHS of the IN operator.
//	**
//	** When IN_INDEX_LOOP is used (and the b-tree will be used to iterate
//	** through the set members) then the b-tree must not contain duplicates.
//	** An ephemeral table will be created unless the selected columns are guaranteed
//	** to be unique - either because it is an INTEGER PRIMARY KEY or due to
//	** a UNIQUE constraint or index.
//	**
//	** When IN_INDEX_MEMBERSHIP is used (and the b-tree will be used
//	** for fast set membership tests) then an ephemeral table must
//	** be used unless <columns> is a single INTEGER PRIMARY KEY column or an
//	** index can be found with the specified <columns> as its left-most.
//	**
//	** If the IN_INDEX_NOOP_OK and IN_INDEX_MEMBERSHIP are both set and
//	** if the RHS of the IN operator is a list (not a subquery) then this
//	** routine might decide that creating an ephemeral b-tree for membership
//	** testing is too expensive and return IN_INDEX_NOOP.  In that case, the
//	** calling routine should implement the IN operator using a sequence
//	** of Eq or Ne comparison operations.
//	**
//	** When the b-tree is being used for membership tests, the calling function
//	** might need to know whether or not the RHS side of the IN operator
//	** contains a NULL.  If prRhsHasNull is not a NULL pointer and
//	** if there is any chance that the (...) might contain a NULL value at
//	** runtime, then a register is allocated and the register number written
//	** to *prRhsHasNull. If there is no chance that the (...) contains a
//	** NULL value, then *prRhsHasNull is left unchanged.
//	**
//	** If a register is allocated and its location stored in *prRhsHasNull, then
//	** the value in that register will be NULL if the b-tree contains one or more
//	** NULL values, and it will be some non-NULL value if the b-tree contains no
//	** NULL values.
//	**
//	** If the aiMap parameter is not NULL, it must point to an array containing
//	** one element for each column returned by the SELECT statement on the RHS
//	** of the IN(...) operator. The i'th entry of the array is populated with the
//	** offset of the index column that matches the i'th column returned by the
//	** SELECT. For example, if the expression and selected index are:
//	**
//	**   (?,?,?) IN (SELECT a, b, c FROM t1)
//	**   CREATE INDEX i1 ON t1(b, c, a);
//	**
//	** then aiMap[] is populated with {2, 0, 1}.

//	** That is the only documented guarantee.  However, countless applications
//	** developed over the years have made baseless assumptions about column names

//	** when modifying this routine to avoid breaking legacy.
//	**
//	** See Also: sqlite3ColumnsFromExprList()

//	** The PRAGMA short_column_names and PRAGMA full_column_names settings are
//	** deprecated.  The default setting is short=ON, full=OFF.  99.9% of all
//	** applications should operate this way.  Nevertheless, we need to support the
//	** other modes for legacy:
//	**
//	**    short=OFF, full=OFF:      Column name is the text of the expression has it
//	**                              originally appears in the SELECT statement.  In
//	**                              other words, the zSpan of the result expression.
//	**
//	**    short=ON, full=OFF:       (This is the default setting).  If the result
//	**                              refers directly to a table column, then the
//	**                              result column name is just the table column
//	**                              name: COLUMN.  Otherwise use zSpan.
//	**
//	**    full=ON, short=ANY:       If the result refers directly to a table column,
//	**                              then the result column name with the table name

//	** Generate code to do constraint checks prior to an INSERT or an UPDATE
//	** on table pTab.
//	**
//	** The regNewData parameter is the first register in a range that contains
//	** the data to be inserted or the data after the update.  There will be
//	** pTab->nCol+1 registers in this range.  The first register (the one
//	** that regNewData points to) will contain the new rowid, or NULL in the
//	** case of a WITHOUT ROWID table.  The second register in the range will
//	** contain the content of the first table column.  The third register will
//	** contain the content of the second table column.  And so forth.
//	**
//	** The regOldData parameter is similar to regNewData except that it contains
//	** the data prior to an UPDATE rather than afterwards.  regOldData is zero
//	** for an INSERT.  This routine can distinguish between UPDATE and INSERT by
//	** checking regOldData for zero.
//	**
//	** For an UPDATE, the pkChng boolean is true if the true primary key (the
//	** rowid for a normal table or the PRIMARY KEY for a WITHOUT ROWID table)
//	** might be modified by the UPDATE.  If pkChng is false, then the key of
//	** the iDataCur content table is guaranteed to be unchanged by the UPDATE.
//	**
//	** For an INSERT, the pkChng boolean indicates whether or not the rowid
//	** was explicitly specified as part of the INSERT statement.  If pkChng
//	** is zero, it means that the either rowid is computed automatically or
//	** that the table is a WITHOUT ROWID table and has no rowid.  On an INSERT,
//	** pkChng will only be true if the INSERT statement provides an integer
//	** value for either the rowid column or its INTEGER PRIMARY KEY alias.
//	**
//	** The code generated by this routine will store new index entries into
//	** registers identified by aRegIdx[].  No index entry is created for
//	** indices where aRegIdx[i]==0.  The order of indices in aRegIdx[] is
//	** the same as the order of indices on the linked list of indices
//	** at pTab->pIndex.
//	**
//	** (2019-05-07) The generated code also creates a new record for the
//	** main table, if pTab is a rowid table, and stores that record in the
//	** register identified by aRegIdx[nIdx] - in other words in the first
//	** entry of aRegIdx[] past the last index.  It is important that the
//	** record be generated during constraint checks to avoid affinity changes
//	** to the register content that occur after constraint checks but before
//	** the new record is inserted.
//	**
//	** The caller must have already opened writeable cursors on the main
//	** table and all applicable indices (that is to say, all indices for which
//	** aRegIdx[] is not zero).  iDataCur is the cursor for the main table when
//	** inserting or updating a rowid table, or the cursor for the PRIMARY KEY
//	** index when operating on a WITHOUT ROWID table.  iIdxCur is the cursor
//	** for the first index in the pTab->pIndex list.  Cursors for other indices
//	** are at iIdxCur+N for the N-th element of the pTab->pIndex list.
//	**
//	** This routine also generates code to check constraints.  NOT NULL,
//	** CHECK, and UNIQUE constraints are all checked.  If a constraint fails,
//	** then the appropriate action is performed.  There are five possible
//	** actions: ROLLBACK, ABORT, FAIL, REPLACE, and IGNORE.
//	**
//	**  Constraint type  Action       What Happens
//	**  ---------------  ----------   ----------------------------------------
//	**  any              ROLLBACK     The current transaction is rolled back and
//	**                                sqlite3_step() returns immediately with a
//	**                                return code of SQLITE_CONSTRAINT.
//	**
//	**  any              ABORT        Back out changes from the current command
//	**                                only (do not do a complete rollback) then
//	**                                cause sqlite3_step() to return immediately
//	**                                with SQLITE_CONSTRAINT.
//	**
//	**  any              FAIL         Sqlite3_step() returns immediately with a
//	**                                return code of SQLITE_CONSTRAINT.  The
//	**                                transaction is not rolled back and any
//	**                                changes to prior rows are retained.
//	**
//	**  any              IGNORE       The attempt in insert or update the current
//	**                                row is skipped, without throwing an error.
//	**                                Processing continues with the next row.
//	**                                (There is an immediate jump to ignoreDest.)
//	**
//	**  NOT NULL         REPLACE      The NULL value is replace by the default
//	**                                value for that column.  If the default value
//	**                                is NULL, the action is the same as ABORT.
//	**
//	**  UNIQUE           REPLACE      The other row that conflicts with the row
//	**                                being inserted is removed.
//	**
//	**  CHECK            REPLACE      Illegal.  The results in an exception.
//	**
//	** Which action to take is determined by the overrideError parameter.
//	** Or if overrideError==OE_Default, then the pParse->onError parameter
//	** is used.  Or if pParse->onError==OE_Default then the onError value
//	** for the constraint is used.

//	**
//	** Preconditions:
//	**
//	**   1.  iDataCur is an open cursor on the btree that is the canonical data
//	**       store for the table.  (This will be either the table itself,
//	**       in the case of a rowid table, or the PRIMARY KEY index in the case
//	**       of a WITHOUT ROWID table.)
//	**
//	**   2.  Read/write cursors for all indices of pTab must be open as
//	**       cursor number iIdxCur+i for the i-th index.
//	**
//	**   3.  The primary key for the row to be deleted must be stored in a
//	**       sequence of nPk memory cells starting at iPk.  If nPk==0 that means
//	**       that a search record formed from OP_MakeRecord is contained in the
//	**       single memory location iPk.
//	**
//	** eMode:
//	**   Parameter eMode may be passed either ONEPASS_OFF (0), ONEPASS_SINGLE, or
//	**   ONEPASS_MULTI.  If eMode is not ONEPASS_OFF, then the cursor
//	**   iDataCur already points to the row to delete. If eMode is ONEPASS_OFF
//	**   then this function must seek iDataCur to the entry identified by iPk
//	**   and nPk before reading from it.
//	**
//	**   If eMode is ONEPASS_MULTI, then this call is being made as part
//	**   of a ONEPASS delete that affects multiple rows. In this case, if
//	**   iIdxNoSeek is a valid cursor number (>=0) and is not the same as
//	**   iDataCur, then its position should be preserved following the delete
//	**   operation. Or, if iIdxNoSeek is not a valid cursor number, the
//	**   position of iDataCur should be preserved instead.
//	**
//	** iIdxNoSeek:
//	**   If iIdxNoSeek is a valid cursor number (>=0) not equal to iDataCur,
//	**   then it identifies an index cursor (from within array of cursors
//	**   starting at iIdxCur) that already points to the index entry to be deleted.
//	**   Except, this optimization is disabled if there are BEFORE triggers since
//	**   the trigger body might have moved the cursor.

//	** This routine is called to handle SQL of the following forms:
//	**
//	**    insert into TABLE (IDLIST) values(EXPRLIST),(EXPRLIST),...
//	**    insert into TABLE (IDLIST) select
//	**    insert into TABLE (IDLIST) default values
//	**
//	** The IDLIST following the table name is always optional.  If omitted,
//	** then a list of all (non-hidden) columns for the table is substituted.
//	** The IDLIST appears in the pColumn parameter.  pColumn is NULL if IDLIST
//	** is omitted.
//	**
//	** For the pSelect parameter holds the values to be inserted for the
//	** first two forms shown above.  A VALUES clause is really just short-hand
//	** for a SELECT statement that omits the FROM clause and everything else
//	** that follows.  If the pSelect parameter is NULL, that means that the
//	** DEFAULT VALUES form of the INSERT statement is intended.
//	**
//	** The code generated follows one of four templates.  For a simple
//	** insert with data coming from a single-row VALUES clause, the code executes
//	** once straight down through.  Pseudo-code follows (we call this
//	** the "1st template"):
//	**
//	**         open write cursor to <table> and its indices
//	**         put VALUES clause expressions into registers
//	**         write the resulting record into <table>
//	**         cleanup
//	**
//	** The three remaining templates assume the statement is of the form
//	**
//	**   INSERT INTO <table> SELECT ...
//	**
//	** If the SELECT clause is of the restricted form "SELECT * FROM <table2>" -
//	** in other words if the SELECT pulls all columns from a single table
//	** and there is no WHERE or LIMIT or GROUP BY or ORDER BY clauses, and
//	** if <table2> and <table1> are distinct tables but have identical
//	** schemas, including all the same indices, then a special optimization
//	** is invoked that copies raw records from <table2> over to <table1>.
//	** See the xferOptimization() function for the implementation of this
//	** template.  This is the 2nd template.
//	**
//	**         open a write cursor to <table>
//	**         open read cursor on <table2>
//	**         transfer all records in <table2> over to <table>
//	**         close cursors
//	**         foreach index on <table>
//	**           open a write cursor on the <table> index
//	**           open a read cursor on the corresponding <table2> index
//	**           transfer all records from the read to the write cursors
//	**           close cursors
//	**         end foreach
//	**
//	** The 3rd template is for when the second template does not apply
//	** and the SELECT clause does not read from <table> at any time.
//	** The generated code follows this template:
//	**
//	**         X <- A
//	**         goto B
//	**      A: setup for the SELECT
//	**         loop over the rows in the SELECT
//	**           load values into registers R..R+n
//	**           yield X
//	**         end loop
//	**         cleanup after the SELECT
//	**         end-coroutine X
//	**      B: open write cursor to <table> and its indices
//	**      C: yield X, at EOF goto D
//	**         insert the select result into <table> from R..R+n
//	**         goto C
//	**      D: cleanup
//	**
//	** The 4th template is used if the insert statement takes its
//	** values from a SELECT but the data is being inserted into a table
//	** that is also read as part of the SELECT.  In the third form,
//	** we have to use an intermediate table to store the results of
//	** the select.  The template is like this:
//	**
//	**         X <- A
//	**         goto B
//	**      A: setup for the SELECT
//	**         loop over the tables in the SELECT
//	**           load value into register R..R+n
//	**           yield X
//	**         end loop
//	**         cleanup after the SELECT
//	**         end co-routine R
//	**      B: open temp table
//	**      L: yield X, at EOF goto M
//	**         insert row from R..R+n into temp table
//	**         goto L
//	**      M: open write cursor to <table> and its indices
//	**         rewind temp table
//	**      C: loop over rows of intermediate table
//	**           transfer values form intermediate table into <table>
//	**         end loop

//	** This function is used to parse both URIs and non-URI filenames passed by the
//	** user to API functions sqlite3_open() or sqlite3_open_v2(), and for database
//	** URIs specified as part of ATTACH statements.
//	**
//	** The first argument to this function is the name of the VFS to use (or
//	** a NULL to signify the default VFS) if the URI does not contain a "vfs=xxx"
//	** query parameter. The second argument contains the URI (or non-URI filename)
//	** itself. When this function is called the *pFlags variable should contain
//	** the default flags to open the database handle with. The value stored in
//	** *pFlags may be updated before returning if the URI filename contains
//	** "cache=xxx" or "mode=xxx" query parameters.
//	**
//	** If successful, SQLITE_OK is returned. In this case *ppVfs is set to point to
//	** the VFS that should be used to open the database file. *pzFile is set to
//	** point to a buffer containing the name of the file to open.  The value
//	** stored in *pzFile is a database name acceptable to sqlite3_uri_parameter()
//	** and is in the same format as names created using sqlite3_create_filename().
//	** The caller must invoke sqlite3_free_filename() (not sqlite3_free()!) on
//	** the value returned in *pzFile to avoid a memory leak.
//	**
//	** If an error occurs, then an SQLite error code is returned and *pzErrMsg
//	** may be set to point to a buffer containing an English language error
//	** message. It is the responsibility of the caller to eventually release
//	** this buffer by calling sqlite3_free().

		 **
		 ** DETERMINATION OF WHEN TO RUN ANALYZE
		 **
		 ** In the current implementation, a table is analyzed if only if all of
		 ** the following are true:
		 **
		 ** (1) MASK bit 0x00002 is set.
		 **
		 ** (2) The table is an ordinary table, not a virtual table or view.
		 **
		 ** (3) The table name does not begin with "sqlite_".
		 **
		 ** (4) One or more of the following is true:
		 **      (4a) The 0x10000 MASK bit is set.
		 **      (4b) One or more indexes on the table lacks an entry
		 **           in the sqlite_stat1 table.
		 **      (4c) The query planner used sqlite_stat1-style statistics for one
		 **           or more indexes of the table at some point during the lifetime
		 **           of the current connection.
		 **
		 ** (5) One or more of the following is true:
		 **      (5a) One or more indexes on the table lacks an entry
		 **           in the sqlite_stat1 table.  (Same as 4a)
		 **      (5b) The number of rows in the table has increased or decreased by
		 **           10-fold.  In other words, the current size of the table is
		 **           10 times larger than the size in sqlite_stat1 or else the
		 **           current size is less than 1/10th the size in sqlite_stat1.
		 **
		 ** The rules for when tables are analyzed are likely to change in
		 ** future releases.  Future versions of SQLite might accept a string

		 ** What follows is a massive switch statement where each case implements a
		 ** separate instruction in the virtual machine.  If we follow the usual
		 ** indentation conventions, each case should be indented by 6 spaces.  But
		 ** that is a lot of wasted space on the left margin.  So the code within
		 ** the switch statement will break with convention and be flush-left. Another
		 ** big comment (similar to this one) will mark the point in the code where
		 ** we transition back to normal indentation.
		 **
		 ** The formatting of each case is important.  The makefile for SQLite
		 ** generates two C files "opcodes.h" and "opcodes.c" by scanning this
		 ** file looking for lines that begin with "case OP_".  The opcodes.h files
		 ** will be filled with #defines that give unique integer values to each
		 ** opcode and the opcodes.c file is filled with an array of strings where
		 ** each string is the symbolic name for the corresponding opcode.  If the
		 ** case statement is followed by a comment of the form "/# same as ... #/"
		 ** that comment is used to determine the particular value of the opcode.
		 **
		 ** Other keywords in the comment that follows each case are used to
		 ** construct the OPFLG_INITIALIZER value that initializes opcodeProperty[].
		 ** Keywords include: in1, in2, in3, out2, out3.  See
		 ** the mkopcodeh.awk script for additional information.
		 **
		 ** Documentation about VDBE opcodes is generated by scanning this file
		 ** for lines of that contain "Opcode:".  That line and all subsequent
		 ** comment lines are used in the generation of the opcode.html documentation
		 ** file.
		 **
		 ** SUMMARY:

		 ** Synopsis: Scan-ahead up to P1 rows
		 **
		 ** This opcode is a prefix opcode to OP_SeekGE.  In other words, this
		 ** opcode must be immediately followed by OP_SeekGE. This constraint is
		 ** checked by assert() statements.
		 **
		 ** This opcode uses the P1 through P4 operands of the subsequent
		 ** OP_SeekGE.  In the text that follows, the operands of the subsequent
		 ** OP_SeekGE opcode are denoted as SeekOP.P1 through SeekOP.P4.   Only
		 ** the P1, P2 and P5 operands of this opcode are also used, and  are called
		 ** This.P1, This.P2 and This.P5.
		 **
		 ** This opcode helps to optimize IN operators on a multi-column index
		 ** where the IN operator is on the later terms of the index by avoiding
		 ** unnecessary seeks on the btree, substituting steps to the next row
		 ** of the b-tree instead.  A correct answer is obtained if this opcode
		 ** is omitted or is a no-op.
		 **
		 ** The SeekGE.P3 and SeekGE.P4 operands identify an unpacked key which
		 ** is the desired entry that we want the cursor SeekGE.P1 to be pointing
		 ** to.  Call this SeekGE.P3/P4 row the "target".
		 **
		 ** If the SeekGE.P1 cursor is not currently pointing to a valid row,
		 ** then this opcode is a no-op and control passes through into the OP_SeekGE.
		 **
		 ** If the SeekGE.P1 cursor is pointing to a valid row, then that row
		 ** might be the target row, or it might be near and slightly before the
		 ** target row, or it might be after the target row.  If the cursor is
		 ** currently before the target row, then this opcode attempts to position
		 ** the cursor on or after the target row by invoking sqlite3BtreeStep()
		 ** on the cursor between 1 and This.P1 times.
		 **
		 ** The This.P5 parameter is a flag that indicates what to do if the
		 ** cursor ends up pointing at a valid row that is past the target
		 ** row.  If This.P5 is false (0) then a jump is made to SeekGE.P2.  If

** M is the type of branch.  I is the direction taken for this instance of
** the branch.
**
**   M: 2 - two-way branch (I=0: fall-thru   1: jump                )
**      3 - two-way + NULL (I=0: fall-thru   1: jump      2: NULL   )
**      4 - OP_Jump        (I=0: jump p1     1: jump p2   2: jump p3)
**
** In other words, if M is 2, then I is either 0 (for fall-through) or
** 1 (for when the branch is taken).  If M is 3, the I is 0 for an
** ordinary fall-through, I is 1 if the branch was taken, and I is 2
** if the result of comparison is NULL.  For M=3, I=2 the jump may or
** may not be taken, depending on the SQLITE_JUMPIFNULL flags in p5.
** When M is 4, that means that an OP_Jump is being run.  I is 0, 1, or 2
** depending on if the operands are less than, equal, or greater than.
**
** iSrcLine is the source code line (from the __LINE__ macro) that
** generated the VDBE instruction combined with flag bits.  The source
** code line number is in the lower 24 bits of iSrcLine and the upper
** 8 bytes are flags.  The lower three bits of the flags indicate
** values for I that should never occur.  For example, if the branch is
** always taken, the flags should be 0x05 since the fall-through and
** alternate branch are never taken.  If a branch is never taken then
** flags should be 0x06 since only the fall-through approach is allowed.
**
** Bit 0x08 of the flags indicates an OP_Jump opcode that is only
** interested in equal or not-equal.  In other words, I==0 and I==2
** should be treated as equivalent
**

//	/*
//	** Generate the beginning of the loop used for WHERE clause processing.
//	** The return value is a pointer to an opaque structure that contains
//	** information needed to terminate the loop.  Later, the calling routine
//	** should invoke sqlite3WhereEnd() with the return value of this function
//	** in order to complete the WHERE clause processing.
//	**
//	** If an error occurs, this routine returns NULL.
//	**
//	** The basic idea is to do a nested loop, one loop for each table in
//	** the FROM clause of a select.  (INSERT and UPDATE statements are the
//	** same as a SELECT with only a single table in the FROM clause.)  For
//	** example, if the SQL is this:
//	**
//	**       SELECT * FROM t1, t2, t3 WHERE ...;
//	**
//	** Then the code generated is conceptually like the following:
//	**
//	**      foreach row1 in t1 do       \    Code generated
//	**        foreach row2 in t2 do      |-- by sqlite3WhereBegin()
//	**          foreach row3 in t3 do   /
//	**            ...
//	**          end                     \    Code generated
//	**        end                        |-- by sqlite3WhereEnd()
//	**      end                         /
//	**
//	** Note that the loops might not be nested in the order in which they
//	** appear in the FROM clause if a different order is better able to make
//	** use of indices.  Note also that when the IN operator appears in
//	** the WHERE clause, it might result in additional nested loops for
//	** scanning through all values on the right-hand side of the IN.
//	**
//	** There are Btree cursors associated with each table.  t1 uses cursor
//	** number pTabList->a[0].iCursor.  t2 uses the cursor pTabList->a[1].iCursor.
//	** And so forth.  This routine generates code to open those VDBE cursors
//	** and sqlite3WhereEnd() generates the code to close them.
//	**
//	** The code that sqlite3WhereBegin() generates leaves the cursors named
//	** in pTabList pointing at their appropriate entries.  The [...] code
//	** can use OP_Column and OP_Rowid opcodes on these cursors to extract
//	** data from the various tables of the loop.
//	**
//	** If the WHERE clause is empty, the foreach loops must each scan their
//	** entire tables.  Thus a three-way join is an O(N^3) operation.  But if
//	** the tables have indices and there are terms in the WHERE clause that
//	** refer to those indices, a complete table scan can be avoided and the
//	** code will run much faster.  Most of the work of this routine is checking
//	** to see if there are indices that can be used to speed up the loop.
//	**
//	** Terms of the WHERE clause are also used to limit which rows actually
//	** make it to the "..." in the middle of the loop.  After each "foreach",
//	** terms of the WHERE clause that use only terms in that loop and outer
//	** loops are evaluated and if false a jump is made around all subsequent
//	** inner loops (or around the "..." if the test occurs within the inner-
//	** most loop)
//	**
//	** OUTER JOINS
//	**
//	** An outer join of tables t1 and t2 is conceptually coded as follows:
//	**
//	**    foreach row1 in t1 do
//	**      flag = 0
//	**      foreach row2 in t2 do
//	**        start:
//	**          ...
//	**          flag = 1
//	**      end
//	**      if flag==0 then
//	**        move the row2 cursor to a null row
//	**        goto start
//	**      fi
//	**    end
//	**
//	** ORDER BY CLAUSE PROCESSING
//	**
//	** pOrderBy is a pointer to the ORDER BY clause (or the GROUP BY clause
//	** if the WHERE_GROUPBY flag is set in wctrlFlags) of a SELECT statement
//	** if there is one.  If there is no ORDER BY clause or if this routine
//	** is called from an UPDATE or DELETE statement, then pOrderBy is NULL.
//	**
//	** The iIdxCur parameter is the cursor number of an index.  If
//	** WHERE_OR_SUBCLAUSE is set, iIdxCur is the cursor number of an index
//	** to use for OR clause processing.  The WHERE clause should use this
//	** specific cursor.  If WHERE_ONEPASS_DESIRED is set, then iIdxCur is
//	** the first cursor in an array of cursors for all indices.  iIdxCur should
//	** be used to compute the appropriate cursor depending on which index is
//	** used.

/*
** SELECT REWRITING
**
**   Any SELECT statement that contains one or more window functions in
**   either the select list or ORDER BY clause (the only two places window
**   functions may be used) is transformed by function sqlite3WindowRewrite()
**   in order to support window function processing. For example, with the
**   schema:
**
**     CREATE TABLE t1(a, b, c, d, e, f, g);
**
**   the statement:
**
**     SELECT a+1, max(b) OVER (PARTITION BY c ORDER BY d) FROM t1 ORDER BY e;
**
**   is transformed to:
**
**     SELECT a+1, max(b) OVER (PARTITION BY c ORDER BY d) FROM (
**         SELECT a, e, c, d, b FROM t1 ORDER BY c, d
**     ) ORDER BY e;
**
**   The flattening optimization is disabled when processing this transformed
**   SELECT statement. This allows the implementation of the window function
**   (in this case max()) to process rows sorted in order of (c, d), which
**   makes things easier for obvious reasons. More generally:
**
**     * FROM, WHERE, GROUP BY and HAVING clauses are all moved to
**       the sub-query.
**
**     * ORDER BY, LIMIT and OFFSET remain part of the parent query.
**
**     * Terminals from each of the expression trees that make up the
**       select-list and ORDER BY expressions in the parent query are
**       selected by the sub-query. For the purposes of the transformation,
**       terminals are column references and aggregate functions.
**
**   If there is more than one window function in the SELECT that uses
**   the same window declaration (the OVER bit), then a single scan may
**   be used to process more than one window function. For example:
**
**     SELECT max(b) OVER (PARTITION BY c ORDER BY d),
**            min(e) OVER (PARTITION BY c ORDER BY d)
**     FROM t1;
**
**   is transformed in the same way as the example above. However:
**
**     SELECT max(b) OVER (PARTITION BY c ORDER BY d),
**            min(e) OVER (PARTITION BY a ORDER BY b)
**     FROM t1;
**
**   Must be transformed to:
**
**     SELECT max(b) OVER (PARTITION BY c ORDER BY d) FROM (
**         SELECT e, min(e) OVER (PARTITION BY a ORDER BY b), c, d, b FROM
**           SELECT a, e, c, d, b FROM t1 ORDER BY a, b
**         ) ORDER BY c, d
**     ) ORDER BY e;
**
**   so that both min() and max() may process rows in the order defined by
**   their respective window declarations.
**
** INTERFACE WITH SELECT.C
**
**   When processing the rewritten SELECT statement, code in select.c calls
**   sqlite3WhereBegin() to begin iterating through the results of the
**   sub-query, which is always implemented as a co-routine. It then calls
**   sqlite3WindowCodeStep() to process rows and finish the scan by calling
**   sqlite3WhereEnd().
**
**   sqlite3WindowCodeStep() generates VM code so that, for each row returned
**   by the sub-query a sub-routine (OP_Gosub) coded by select.c is invoked.
**   When the sub-routine is invoked:
**
**     * The results of all window-functions for the row are stored
**       in the associated Window.regResult registers.
**
**     * The required terminal values are stored in the current row of
**       temp table Window.iEphCsr.
**
**   In some cases, depending on the window frame and the specific window
**   functions invoked, sqlite3WindowCodeStep() caches each entire partition
**   in a temp table before returning any rows. In other cases it does not.
**   This detail is encapsulated within this file, the code generated by
**   select.c is the same in either case.
**
** BUILT-IN WINDOW FUNCTIONS
**
**   This implementation features the following built-in window functions:
**
**     row_number()
**     rank()
**     dense_rank()
**     percent_rank()
**     cume_dist()
**     ntile(N)
**     lead(expr [, offset [, default]])
**     lag(expr [, offset [, default]])
**     first_value(expr)
**     last_value(expr)
**     nth_value(expr, N)
**
**   These are the same built-in window functions supported by Postgres.
**   Although the behaviour of aggregate window functions (functions that
**   can be used as either aggregates or window functions) allows them to
**   be implemented using an API, built-in window functions are much more
**   esoteric. Additionally, some window functions (e.g. nth_value())
**   may only be implemented by caching the entire partition in memory.
**   As such, some built-in window functions use the same API as aggregate
**   window functions and some are implemented directly using VDBE
**   instructions. Additionally, for those functions that use the API, the
**   window frame is sometimes modified before the SELECT statement is
**   rewritten. For example, regardless of the specified window frame, the
**   row_number() function always uses:
**
**     ROWS BETWEEN UNBOUNDED PRECEDING AND CURRENT ROW
**
**   See sqlite3WindowUpdate() for details.
**
**   As well as some of the built-in window functions, aggregate window
**   functions min() and max() are implemented using VDBE instructions if
**   the start of the window frame is declared as anything other than
**   UNBOUNDED PRECEDING.

//	** Also requiring special handling are the cases:
//	**
//	**   ROWS BETWEEN <expr1> PRECEDING AND <expr2> PRECEDING
//	**   ROWS BETWEEN <expr1> FOLLOWING AND <expr2> FOLLOWING
//	**
//	** when (expr1 < expr2). This is detected at runtime, not by this function.
//	** To handle this case, the pseudo-code programs depicted above are modified
//	** slightly to be:
//	**
//	**     ... loop started by sqlite3WhereBegin() ...
//	**     if( new partition ){
//	**       Gosub flush
//	**     }
//	**     Insert new row into eph table.
//	**     if( first row of partition ){
//	**       Rewind(csrEnd) ; Rewind(csrStart) ; Rewind(csrCurrent)
//	**       regEnd = <expr2>
//	**       regStart = <expr1>
//	**       if( regEnd < regStart ){
//	**         RETURN_ROW
//	**         delete eph table contents
//	**         continue
//	**       }
//	**     ...
//	**
//	** The new "continue" statement in the above jumps to the next iteration
//	** of the outer loop - the one started by sqlite3WhereBegin().
//	**
//	** The various GROUPS cases are implemented using the same patterns as
//	** ROWS. The VM code is modified slightly so that:
//	**
//	**   1. The else branch in the main loop is only taken if the row just
//	**      added to the ephemeral table is the start of a new group. In
//	**      other words, it becomes:
//	**
//	**         ... loop started by sqlite3WhereBegin() ...
//	**         if( new partition ){
//	**           Gosub flush
//	**         }
//	**         Insert new row into eph table.
//	**         if( first row of partition ){
//	**           Rewind(csrEnd) ; Rewind(csrStart) ; Rewind(csrCurrent)
//	**           regEnd = <expr2>
//	**           regStart = <expr1>
//	**         }else if( new group ){
//	**           ...
//	**         }
//	**       }
//	**
//	**   2. Instead of processing a single row, each RETURN_ROW, AGGSTEP or
//	**      AGGINVERSE step processes the current row of the relevant cursor and
//	**      all subsequent rows belonging to the same group.
//	**
//	** RANGE window frames are a little different again. As for GROUPS, the
//	** main loop runs once per group only. And RETURN_ROW, AGGSTEP and AGGINVERSE
//	** deal in groups instead of rows. As for ROWS and GROUPS, there are three
//	** basic cases:
//	**
//	**   RANGE BETWEEN <expr1> PRECEDING AND <expr2> FOLLOWING
//	**
//	**     ... loop started by sqlite3WhereBegin() ...
//	**       if( new partition ){
//	**         Gosub flush
//	**       }
//	**       Insert new row into eph table.
//	**       if( first row of partition ){
//	**         Rewind(csrEnd) ; Rewind(csrStart) ; Rewind(csrCurrent)
//	**         regEnd = <expr2>
//	**         regStart = <expr1>
//	**       }else{
//	**         AGGSTEP
//	**         while( (csrCurrent.key + regEnd) < csrEnd.key ){
//	**           RETURN_ROW
//	**           while( csrStart.key + regStart) < csrCurrent.key ){
//	**             AGGINVERSE
//	**           }
//	**         }
//	**       }
//	**     }
//	**     flush:
//	**       AGGSTEP
//	**       while( 1 ){
//	**         RETURN ROW
//	**         if( csrCurrent is EOF ) break;
//	**           while( csrStart.key + regStart) < csrCurrent.key ){

/******************************************************************************
************************** Begin Proxy Locking ********************************
**
** Proxy locking is a "uber-locking-method" in this sense:  It uses the
** other locking methods on secondary lock files.  Proxy locking is a
** meta-layer over top of the primitive locking implemented above.  For
** this reason, the division that implements of proxy locking is deferred
** until late in the file (here) after all of the other I/O methods have
** been defined - so that the primitive locking methods are available
** as services to help with the implementation of proxy locking.
**
****
**
** The default locking schemes in SQLite use byte-range locks on the
** database file to coordinate safe, concurrent access by multiple readers
** and writers [http://sqlite.org/lockingv3.html].  The five file locking
** states (UNLOCKED, PENDING, SHARED, RESERVED, EXCLUSIVE) are implemented
** as POSIX read & write locks over fixed set of locations (via fsctl),
** on AFP and SMB only exclusive byte-range locks are available via fsctl
** with _IOWR('z', 23, struct ByteRangeLockPB2) to track the same 5 states.
** To simulate a F_RDLCK on the shared range, on AFP a randomly selected
** address in the shared range is taken for a SHARED lock, the entire
** shared range is taken for an EXCLUSIVE lock):
**
**      PENDING_BYTE        0x40000000
**      RESERVED_BYTE       0x40000001
**      SHARED_RANGE        0x40000002 -> 0x40000200
**
** This works well on the local file system, but shows a nearly 100x
** slowdown in read performance on AFP because the AFP client disables
** the read cache when byte-range locks are present.  Enabling the read
** cache exposes a cache coherency problem that is present on all OS X
** supported network file systems.  NFS and AFP both observe the
** close-to-open semantics for ensuring cache coherency
** [http://nfs.sourceforge.net/#faq_a8], which does not effectively
** address the requirements for concurrent database access by multiple
** readers and writers
** [http://www.nabble.com/SQLite-on-NFS-cache-coherency-td15655701.html].
**
** To address the performance and cache coherency issues, proxy file locking
** changes the way database access is controlled by limiting access to a
** single host at a time and moving file locks off of the database file
** and onto a proxy file on the local file system.
**
**
** Using proxy locks
** -----------------
**
** C APIs
**
**  sqlite3_file_control(db, dbname, SQLITE_FCNTL_SET_LOCKPROXYFILE,
**                       <proxy_path> | ":auto:");
**  sqlite3_file_control(db, dbname, SQLITE_FCNTL_GET_LOCKPROXYFILE,
**                       &<proxy_path>);
**
**
** SQL pragmas
**
**  PRAGMA [database.]lock_proxy_file=<proxy_path> | :auto:
**  PRAGMA [database.]lock_proxy_file
**
** Specifying ":auto:" means that if there is a conch file with a matching
** host ID in it, the proxy path in the conch file will be used, otherwise
** a proxy path based on the user's temp dir
** (via confstr(_CS_DARWIN_USER_TEMP_DIR,...)) will be used and the
** actual proxy file name is generated from the name and path of the
** database file.  For example:
**
**       For database path "/Users/me/foo.db"
**       The lock path will be "<tmpdir>/sqliteplocks/_Users_me_foo.db:auto:")
**
** Once a lock proxy is configured for a database connection, it can not
** be removed, however it may be switched to a different proxy path via
** the above APIs (assuming the conch file is not being held by another
** connection or process).
**
**
** How proxy locking works
** -----------------------
**
** Proxy file locking relies primarily on two new supporting files:
**
**   *  conch file to limit access to the database file to a single host
**      at a time
**
**   *  proxy file to act as a proxy for the advisory locks normally
**      taken on the database
**
** The conch file - to use a proxy file, sqlite must first "hold the conch"
** by taking an sqlite-style shared lock on the conch file, reading the
** contents and comparing the host's unique host ID (see below) and lock
** proxy path against the values stored in the conch.  The conch file is
** stored in the same directory as the database file and the file name
** is patterned after the database file name as ".<databasename>-conch".
** If the conch file does not exist, or its contents do not match the
** host ID and/or proxy path, then the lock is escalated to an exclusive
** lock and the conch file contents is updated with the host ID and proxy
** path and the lock is downgraded to a shared lock again.  If the conch
** is held by another process (with a shared lock), the exclusive lock
** will fail and SQLITE_BUSY is returned.
**
** The proxy file - a single-byte file used for all advisory file locks
** normally taken on the database file.   This allows for safe sharing
** of the database file for multiple readers and writers on the same
** host (the conch ensures that they all use the same local lock file).
**
** Requesting the lock proxy does not immediately take the conch, it is
** only taken when the first request to lock database file is made.
** This matches the semantics of the traditional locking behavior, where
** opening a connection to a database file does not take a lock on it.
** The shared lock and an open file descriptor are maintained until
** the connection to the database is closed.
**
** The proxy file and the lock file are never deleted so they only need
** to be created the first time they are used.
**
** Configuration options
** ---------------------
**
**  SQLITE_PREFER_PROXY_LOCKING
**
**       Database files accessed on non-local file systems are
**       automatically configured for proxy locking, lock files are
**       named automatically using the same logic as
**       PRAGMA lock_proxy_file=":auto:"
**
**  SQLITE_PROXY_DEBUG
**
**       Enables the logging of error messages during host id file
**       retrieval and creation
**
**  LOCKPROXYDIR
**
**       Overrides the default directory used for lock proxy files that
**       are named automatically via the ":auto:" setting
**
**  SQLITE_DEFAULT_PROXYDIR_PERMISSIONS
**
**       Permissions to use when creating a directory for storing the
**       lock proxy files, only used when LOCKPROXYDIR is not set.
**
**
** As mentioned above, when compiled with SQLITE_PREFER_PROXY_LOCKING,
** setting the environment variable SQLITE_FORCE_PROXY_LOCKING to 1 will
** force proxy locking to be used for every database file opened, and 0
** will force automatic proxy locking to be disabled for all database
** files (explicitly calling the SQLITE_FCNTL_SET_LOCKPROXYFILE pragma or
** sqlite_file_control API is not affected by SQLITE_FORCE_PROXY_LOCKING).

//	** Open a shared-memory area associated with open database file pDbFd.

//	** as the open database file and has the same name as the open database
//	** file with the "-shm" suffix added.  For example, if the database file
//	** is "/home/user1/config.db" then the file that is created and mmapped
//	** for shared memory will be called "/home/user1/config.db-shm".
//	**
//	** Another approach to is to use files in /dev/shm or /dev/tmp or an
//	** some other tmpfs mount. But if a file in a different directory
//	** from the database file is used, then differing access permissions
//	** or a chroot() might cause two different processes on the same
//	** database to end up using different files for shared memory -
//	** meaning that their memory would not really be shared - resulting
//	** in database corruption.  Nevertheless, this tmpfs file usage
//	** can be enabled at compile-time using -DSQLITE_SHM_DIRECTORY="/dev/shm"
//	** or the equivalent.  The use of the SQLITE_SHM_DIRECTORY compile-time
//	** option results in an incompatible build of SQLite;  builds of SQLite
//	** that with differing SQLITE_SHM_DIRECTORY settings attempt to use the
//	** same database file at the same time, database corruption will likely
//	** result. The SQLITE_SHM_DIRECTORY compile-time option is considered
//	** "unsupported" and may go away in a future SQLite release.
//	**
//	** When opening a new shared-memory file, if no other instances of that
//	** file are currently open, in this process or in other processes, then
//	** the file must be truncated to zero length or have its header cleared.
//	**
//	** If the original database file (pDbFd) is using the "unix-excl" VFS
//	** that means that an exclusive lock is held on the database file and
//	** that no other processes are able to read or write the database.  In
//	** that case, we do not really need shared memory.  No shared memory

//	**      WHERE_EXPRIDX    The index is likely a covering index, but it is

//	**                       expressions that are indexed.  Score it as a

//	** Add all WhereLoop objects for a single table of the join where the table

//	**
//	** The costs (WhereLoop.rRun) of the b-tree loops added by this function
//	** are calculated as follows:
//	**
//	** For a full scan, assuming the table (or index) contains nRow rows:
//	**
//	**     cost = nRow * 3.0                    // full-table scan
//	**     cost = nRow * K                      // scan of covering index
//	**     cost = nRow * (K+3.0)                // scan of non-covering index
//	**
//	** where K is a value between 1.1 and 3.0 set based on the relative
//	** estimated average size of the index and table records.
//	**
//	** For an index scan, where nVisit is the number of index rows visited
//	** by the scan, and nSeek is the number of seek operations required on
//	** the index b-tree:
//	**
//	**     cost = nSeek * (log(nRow) + K * nVisit)          // covering index
//	**     cost = nSeek * (log(nRow) + (K+3.0) * nVisit)    // non-covering index
//	**
//	** Normally, nSeek is 1. nSeek values greater than 1 come about if the
//	** WHERE clause includes "x IN (....)" terms used in place of "x=?". Or when
//	** implicit "x IN (SELECT x FROM tbl)" terms are added for skip-scans.
//	**
//	** The estimated values (nRow, nVisit, nSeek) often contain a large amount
//	** of uncertainty.  For this reason, scoring is designed to pick plans that
//	** "do the least harm" if the estimates are inaccurate.  For example, a
//	** log(nRow) factor is omitted from a non-covering index scan in order to
//	** bias the scoring in favor of using an index, since the worst-case
//	** performance of using an index is far better than the worst-case performance
