Back out the change at [47cd634c98b502d4] which was incorrect. Add a test case so that we don't accidently back out that change again. (check-in: 596ac2a4 user: drh tags: trunk)
17:28
Add further comments to window.c. (check-in: 90046456 user: dan tags: trunk)
16:46
New test cases for window functions with RANGE BETWEEN and DESC NULLS FIRST. (check-in: f7002f86 user: drh tags: trunk)
16:14
Fix a bug in RANGE window functions that use "ORDER BY <expr> DESC NULLS FIRST" as the window-frame ORDER BY clause. (check-in: 39b4cad4 user: dan 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)
2019-08-29
23:24
Remove a faulty testcase() macro. (check-in: 80124ae5 user: drh tags: trunk)
21:16
Improve vdbe branch coverage of NULLS LAST code. (check-in: e8e9f77d user: dan tags: trunk)
19:34
Fix other problems similar to ticket [c0390363]. (check-in: 96ff2ba9 user: dan tags: trunk)
16:48
Add a missing VdbeCoverage() macro. (check-in: 33da6092 user: drh tags: trunk)
16:17
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)
00:27
Improve Lemon so that it enlarges some of its tables slightly in order to avoid having to index range checks on table lookups for a performance increase. (check-in: 4be6a23a user: drh tags: trunk)
2019-08-28
11:49
Fix an unreachable branch in sqlite3ParserFallback() (Closed-Leaf check-in: e059178b user: drh tags: lemon-optimization)
11:31
Further improvements to parser speed by enlarging lookup tables to eliminate the need to do range checking on the index prior to lookup. (check-in: 47d3e091 user: drh tags: lemon-optimization)
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
19:59
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)
