| ||
18:49 | Performance improvements when reading large blobs, especially if SQLITE_DIRECT_OVERFLOW_READ is defined. (check-in: 2312eb6a 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: 683dd379 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: e54330b4 user: drh tags: trunk) | |
2014-04-03
| ||
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: d5513dfa user: drh tags: trunk) | |
14:31 | Fix a typo in the "Synopsis:" comment for the OP_VFilter opcode. (check-in: 48ecdd4a user: drh tags: trunk) | |
00:32 | In the command-line shell, run set writable_schema before running the ".clone" command. (check-in: 9d2ae634 user: drh tags: trunk) | |
2014-04-01
| ||
01:24 | Remove an unnecessary conditional, replacing it with an assert(). Improvements to comments. (Closed-Leaf check-in: 834bf1c3 user: drh tags: overflow-pgno-cache) | |
2014-03-31
| ||
23:57 | Fix a compiler warning when SQLITE_DIRECT_OVERFLOW_READ is defined. Minor performance enhancement and size reduction. (check-in: 96385dc4 user: drh tags: overflow-pgno-cache) | |
22:03 | Merge in the latest changes and fixes from trunk. (check-in: f6211540 user: drh tags: overflow-pgno-cache) | |
20:05 | Remove an unnecessary conditional. (Closed-Leaf check-in: 7473c4df user: drh tags: query-plan-experiments) | |
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: b7830d23 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: ea8b0910 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: b3296267 user: drh tags: trunk) | |
2014-03-29
| ||
21:16 | Experiments in picking better query plans, especially when the usage of one index is a subset of another. (check-in: 8f869ca7 user: drh tags: query-plan-experiments) | |
2014-03-28
| ||
19:47 | Fix a compiler warning and an after-OOM memory leak. (check-in: 58f7ca29 user: drh tags: orderby-planning) | |
18:35 | Merge the latest changes from trunk. (check-in: 3047a25f 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: 27deb6e4 user: drh tags: trunk) | |
12:56 | Fix a harmless compiler warning. (check-in: a4e47150 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: 7fa85eaa user: drh tags: trunk) | |
