10 check-ins in a bisect
|
2021-01-25
| ||
| 21:24 | BAD (1) Add an extra log message in the case of an SQLITE_CORRUPT_INDEX error. (check-in: 0571c241 user: drh tags: trunk) | |
|
2020-11-18
| ||
| 18:36 | BAD (3) Add test infrastructure for cksumvfs. And update cksumvfs so that it works in concert with version 2 VFSs. No changes to core SQLite. (check-in: 43d4801d user: dan tags: trunk) | |
|
2020-10-14
| ||
| 15:46 | BAD (5) Enhanced documentation for sqlite3_vtab_nochange() to make it clear that it is an optimization and that virtual table implementations should be prepared for it to always return false. (check-in: 3e264361 user: drh tags: trunk) | |
|
2020-10-02
| ||
| 12:49 | BAD (6) Remove an incorrect assert() from the OP_SeekScan opcode. (check-in: c0400f8c user: drh tags: trunk) | |
|
2020-10-01
| ||
| 14:36 | BAD (7) The IN-early-out optimization does not work for virtual tables. Do not try to use it there. Fix for ticket [2d5a3163563d559f]. Test cases in TH3. (check-in: dbec6910 user: drh tags: trunk) | |
|
2020-09-30
| ||
| 18:06 | BAD (10) Improved query optimization for multi-column indexes where the second or later columns are constrained by an IN operator and the earlier index columns limit the search to a small number of rows. Use the new OP_SeekScan opcode which does scanning of the relevant range of the index but gives up and falls back to doing a seek if the number of rows scanned grows to large, in order to guard against pathological cases where the estimated number of rows to be scanned is far too small. (check-in: 4a43430f user: drh tags: trunk) | |
| 17:32 | GOOD (9) Back out the incorrect optimization of check-in [e51ecadcbdef5ce6] as ticket [5c4e7aa793943803] reports a case where the optimization does not work. (check-in: 7395e96b user: drh tags: trunk) | |
| 09:17 | GOOD (8) Better understanding of savepoint code (check-in: ce6d8d62 user: shearer tags: trunk) | |
|
2020-09-21
| ||
| 14:53 | GOOD (4) In fts5 integrity checks, do not compare the contents of the index against an external content table unless specifically requested. (check-in: 78216369 user: dan tags: trunk) | |
|
2020-08-14
| ||
| 13:23 | GOOD (2) Version 3.33.0 (check-in: fca8dc8b user: drh tags: trunk, release, version-3.33.0) | |
