21:01
Improved fix for ticket [da78413751863] that does not require disabling the query flattener as was done in [005d5b870625]. This also makes the code generator for vector IN operators a little easier to understand. (check-in: 723f1be3 user: drh tags: trunk)
20:22
Add missing entry for SQLITE_IOERR_VNODE to the switch statement in sqlite3ErrName(). (check-in: e2b3e335 user: dan tags: apple-osx)

05:51
Remove some branches in walTryBeginRead() that were added by check-in [ce5d13c2de] but became unreachable with the addition of logic in check-in [18b26843] that enabled read-only clients to parse the WAL file into a heap-memory WAL-index, thus guaranteeing that the WAL-index header is always available. (check-in: 9c6b38b9 user: drh tags: readonly-wal-recovery)
2017-11-11

18:05

01:05
When sqlite3_checker finds a problem, show the row key as part of the error message, not the row index number. (check-in: 6ffe917d user: drh tags: checkindex)
01:01
Actually perform index checks when running sqlite3_checker (check-in: 54530020 user: drh tags: checkindex)
