Performance optimization on sqlite3GenerateConstraintChecks() - bypass the loop that checks each column for NOT NULL constraints if it is known in advance that the table has no NOT NULL constraints. (check-in: e3c3f4d7 user: drh tags: trunk)
16:38
Clarify some comments and add assert() and testcase() macros to the replace-trigger recheck logic for ticket [c1e19e12046d23fe] (check-in: 8c0042bd user: drh tags: trunk)
16:02
Fix a problem in the legacy ".explain on" formatting when it is used on a query with more than 8 output columns. (check-in: 070b4982 user: drh tags: trunk)

12:27
Overnight, OSSFuzz helpfully pointed out a potential use-after-free bug in yesterdays changes, involving continued use of a pointer after the memory pointed to had been realloc()-ed. Thanks Google. (check-in: c422afb5 user: drh tags: trunk)
01:43
Add missing VdbeCoverage() macro. Fix an off-by-one error in partial index handling. New test cases. Ticket [c1e19e12046d23fe] (check-in: 41cc8e3d user: drh tags: trunk)
00:04
If replace triggers are run during uniqueness checking, then rerun all uniqueness checks a second time using the ABORT algorithm. Fix for ticket [c1e19e12046d23fe] (check-in: fbac0c65 user: drh tags: trunk)

Correction to check-in [bec5b6d4d083556d] so that it detects *all* triggers that might perturb the insertion cursor. Ticket [50c09fc2cf0d91ce]. (check-in: 521f1d36 user: drh tags: trunk)
2019-10-23
