Updates to the default settings in Makefile.linux-gcc. check-in: 3044cf69 user: drh tags: trunk
14:27
When we play games with COLLATE in order to commute an operator in the WHERE clause processing, be sure not to use the commuted operator to qualify a partial index, as insufficient COLLATE information is preserved to verify that the expression will correctly qualify the index. Ticket [767a8cbc6d20bd68] check-in: 5351e920 user: drh tags: trunk

02:21
When applying the IN_INDEX_NOOP optimization and the LHS has REAL affinity, also apply REAL affinity to each element of the RHS. Ticket [2841e99d104c6436]. check-in: 88833a9c user: drh tags: trunk

Fix an obsolete comment that defines the meaning of one of the parameters to the sqlite3FindInIndex() subroutine. No changes to code. check-in: 0c946f08 user: drh tags: trunk
00:58
When computing an expression value for an index-on-expression or a CHECK constraint and the expressions uses a REAL table column, but the value of that column is an integer (in other words, when it is using the store-real-as-integer optimization) be sure to promote the value to real before evaluating the expression. Ticket [57af00b6642ecd68]. check-in: 0658c16e user: drh tags: trunk

When the affinity of a table column is INT or REAL, make the affinity of corresponding index columns NUMERIC. This increases the precision of index lookups for large numbers so that it matches the precision of ordinary comparison operators. Ticket [40812aea1fde9594] check-in: e0d909c7 user: drh tags: trunk
23:15
Make sure OP_RealAffinity has been applied to all columns of type REAL in the excluded.* pseudo-table of an UPSERT. Ticket [5a3dba8104421320] check-in: 67381dad user: drh tags: trunk

16:00
The expression "(X IS FALSE) IN (FALSE)" does not imply that X is NOT NULL. Ticket [f8f472cbc77ba9c9] check-in: dd661348 user: drh tags: trunk
15:11
The expression "(X IS FALSE) BETWEEN FALSE AND TRUE" does not implie that X is not NULL. Ticket [fba33c8b1df6a915] check-in: 057fb8b1 user: drh tags: trunk
13:07
The expression "(x IS FALSE) IS FALSE" does not imply that X is not NULL. Ticket [a6408d42b9f44462] check-in: 45ff2b1f user: drh tags: trunk

Remove an unreachable branch in the NULLS LAST logic of RANGE window functions. check-in: 47cd634c user: drh tags: trunk
15:50
Fix another case where SQLite assumes that if "~(? AND FALSE)" is true, "?" must be non-null. check-in: 616f5663 user: dan tags: trunk
15:06
Avoid assuming that for "~ (? AND FALSE)" to be true, "?" must not be NULL, just as we do for "NOT (? AND FALSE)". Fix for ticket [c0390363]. check-in: 84ae41fd user: dan tags: trunk
14:25
Fix a potential buffer overrun in fts5 caused by corrupted database records. check-in: c465d0eb user: dan tags: trunk

02:09
Increase the size of the yy_lookahead table so that it is never necessary to down bounds checking on the index. check-in: bafd8723 user: drh tags: lemon-optimization
2019-08-27

Add support for "ORDER BY ... NULLS FIRST" and "ORDER BY ... NULLS LAST". Use this to fix ticket [f8a7060e]. check-in: 94085fb3 user: dan tags: trunk
17:59
The ALWAYS() added by the previous check-in was incorrect. Take it back out. check-in: 336235db user: drh tags: trunk
17:28
Add ALWAYS() to an always true conditional that results from the previous check-in. Add a test case for ticket [dbaf8a6820be1ece] to supplement those already checked into TH3. check-in: aff20980 user: drh tags: trunk
17:01
Omit the "x IN (y)" to "x==y" optimization of check-in [e68b427afbc82e20] (and ticket [e39d032577df6942]) as it causes difficult affinity problems as demonstrated by ticket [dbaf8a6820be1ece] and the original assertion fault is no longer a factor due to countless other changes of the previous 5 years. check-in: 7f5168a7 user: drh tags: trunk
10:05
If a TEMP TRIGGER references an auxiliary schema, and that auxiliary schema is detached, move the trigger to reference the TEMP schema before completing the detach, so that the trigger does not hold a dangling schema pointer. Ticket [ac8dd4a32ba4322f] check-in: 069c2f4c user: drh tags: trunk
