| 18:49 | Performance improvements when reading large blobs, especially if SQLITE_DIRECT_OVERFLOW_READ is defined. (check-in: 2312eb6a9e user: drh tags: trunk) | |
| 18:20 | Merge changes to the query planner that strive to ensure that any index usage that is a proper subset of some other index usage always has a slightly higher cost. (check-in: 683dd379a2 user: drh tags: trunk) | |
| 14:12 | Ensure the "PRAGMA journal_mode=WAL" works coming from any other journal_mode with ATTACH-ed databases. (check-in: e54330b431 user: drh tags: trunk) | |

| 16:29 | Use OP_Copy instead of OP_SCopy when moving results out of a subquery, to prevent the subquery results from changing out from under the outer query. Fix for ticket [98825a79ce1456]. Problem introduced by check-in [1e64dd782a126f48d78]. (check-in: d5513dfa23 user: drh tags: trunk) | |
| 14:31 | Fix a typo in the "Synopsis:" comment for the OP_VFilter opcode. (check-in: 48ecdd4aff user: drh tags: trunk) | |

| 23:57 | Fix a compiler warning when SQLITE_DIRECT_OVERFLOW_READ is defined. Minor performance enhancement and size reduction. (check-in: 96385dc460 user: drh tags: overflow-pgno-cache) | |
| 22:03 | Merge in the latest changes and fixes from trunk. (check-in: f6211540c9 user: drh tags: overflow-pgno-cache) | |
| 20:05 | Remove an unnecessary conditional. (Closed-Leaf check-in: 7473c4dfc1 user: drh tags: query-plan-experiments) | |
| 19:57 | Add the SQLITE_MAX_WORKER_THREADS compile time option. And the SQLITE_CONFIG_WORKER_THREADS sqlite3_config() switch. (check-in: 2774710df8 user: dan tags: threads) | |
| 19:49 | Also make sure an index that is a proper subset of some other index has a higher cost than that other index. Add test cases. (check-in: b7830d232b user: drh tags: query-plan-experiments) | |
| 18:24 | Make sure that an index that covers a proper superset of the WHERE clause terms of some other index has a lower cost than the other index. (check-in: ea8b091004 user: drh tags: query-plan-experiments) | |
| 13:42 | Avoid a (harmless) buffer overread that is possible on an OOM when MEMSYS5 is engaged. (check-in: b3296267fb user: drh tags: trunk) | |
|

| ||
| 21:16 | Experiments in picking better query plans, especially when the usage of one index is a subset of another. (check-in: 8f869ca7a6 user: drh tags: query-plan-experiments) | |
| 19:48 | Changes to make the multi-threaded sorter sort stably. (Closed-Leaf check-in: 83a105c864 user: dan tags: threads-closed) | |
| 10:01 | Fix a broken assert() in vdbesort.c. (check-in: 18d1b402f2 user: dan tags: threads) | |
| 09:34 | Fix a problem in vdbesort.c causing spurious SQLITE_NOMEM errors when using memsys3 or memsys5. (check-in: a683c05f62 user: dan tags: threads) | |
| 06:27 | Add the optimization to avoid some unnecessary calls to sqlite3VdbeRecordUnpack() added to the trunk by [707ea170b3]. (check-in: fc4d04e6b0 user: dan tags: threads) | |

2014-03-28
| ||
| 19:47 | Fix a compiler warning and an after-OOM memory leak. (check-in: 58f7ca2930 user: drh tags: orderby-planning) | |
| 19:18 | Merge latest changes from orderby-planning branch. (check-in: 4c7fb54234 user: dan tags: threads) | |
| 18:35 | Merge the latest changes from trunk. (check-in: 3047a25f1c user: drh tags: orderby-planning) | |
| 14:41 | Disable the wal64k.test script for non-unix systems since it depends on unix-only features. (check-in: 27deb6e49b user: drh tags: trunk) | |
| 12:56 | Fix a harmless compiler warning. (check-in: a4e47150f3 user: drh tags: trunk) | |
| 03:12 | Enhance the sqlite3VdbeRecordCompare() routines so that if they encounter database corruption, they will set the UnpackedRecord.isCorrupt field and return 0. The sqlite3BtreeMovetoUnpacked() routine detects this and returns SQLITE_CORRUPT, causing the corruption to be reported back to the top-level. (check-in: 7fa85eaaaf user: drh tags: trunk) | |
