Merge enhancements from trunk. (check-in: 4945a662 user: drh tags: approximate-analyze)
19:56
Do not factor out constant functions into the initialization section of a prepared statement, because even though they are constant, they can still throw exceptions. Instead, put such functions in an OP_Once block. This fixes ticket [3c9eadd2a6ba0aa5] and causes COALESCE() and CASE...END to be short-circuit. (check-in: c5f96a08 user: drh tags: trunk)
19:41
Rename sqlite3ExprCodeAtInit() to sqlite3ExprCodeRunJustOnce(). Other changes to make the new code cleaner. Test cases added. (Closed-Leaf check-in: d7f18489 user: drh tags: do-not-factor-functions)

17:58
Do not factor out constant functions into the initialization section at the end of the prepared statement, be cause if they throw an exception, it will abort the statement even if the function is never called.

16:46

The sqlite3ExprCodeFactorable() routine should make a copy of non-factorable expressions, as they might be coming from a DEFAULT or generated column in a table constraint. (check-in: a2d6f108 user: drh tags: trunk)

Change the sqlite3.pDfltColl (the default collating sequence for the database connection) so that it is the collating sequence appropriate for the database encoding, not the UTF8 collating sequence. This helps to ensure that the database encoding collation is always used, even for expressions that do not have an defined collating sequence. Ticket [1b8d7264567eb6fc].

Ensure that the filename passed into the xFullPathname method of the VFS is acceptable as an argument to sqlite3_uri_parameter(). The interface spec does not guarantee this, but it has been so historically and some applications have come to depends on it. (check-in: bfb09371 user: drh tags: trunk)

Update the fuzzcheck test module so that it avoids inserting text values that contain embedded NULs in the XSQL table. Fix some legacy entries in the test/fuzzdata8.db that had embedded NULs.

If STAT4 determines that a WHERE clause term that is not used by an index has very high probability of being true, then do not use that term to reduce the estimated output row count. (check-in: 40739c79 user: drh tags: trunk)
16:46
Rework this changes so that instead of setting the WhereTerm.truthProb when a term is seen to be of low selectivity, it merely sets a new flag (the TERM_HIGHTRUTH flag) which causes whereLoopOutputAdjust() to ignore that term. (Closed-Leaf check-in: 4558163b user: drh tags: stat4-truthprob)

In the OP_Column opcode, if the cursor is marked NullRow (due to being the right table of a LEFT JOIN that does not match) and the cursor is the table cursor for an OR-optimization with a covering index, then do not substitute the covering index cursor, since the covering index cursor does not have the NullRow flag set.
