| 00:33 | Improvements to PRAGMA integrity_check for better detection of malformed records. Integrity_check now avoids returning SQLITE_CORRUPT on a corrupt record.

| 00:13 | PRAGMA integrity_check returns SQLITE_OK even if it encounters corruption while scanning indexes. (Closed-Leaf check-in: 81f62e99f2 user: drh tags: improved-integrity-check) | |
| 00:01 | Fix test script comment. No changes to code. (check-in: a5a1949259 user: mistachkin tags: trunk) | |
