| 19:42 | Remove unused code and fix comments. Final cleanup before merging. (Closed-Leaf check-in: ce42039f56 user: drh tags: bloom-filter) | |
| 18:44 | Enable bloom filters for the right table of a LEFT JOIN. Fix unreachable branches. (check-in: d342ab722d user: drh tags: bloom-filter) | |
| 16:17 | Add ".mode off" and ".mode count" to the CLI. (check-in: b11f4d080a user: drh tags: bloom-filter) | |
| 04:45 | Closer to passing all Tcl tests (with an odd failure) (check-in: 6956e98908 user: larrybr tags: cli_extension) | |
| 01:28 | Add SQLITE_TESTCTRL_LOGEST and enhance the LogEst utility program. Improvements to testability of bloom filters. (check-in: 88b43d798c user: drh tags: bloom-filter) | |
|
2021-12-08
| ||
| 19:50 | Improvements on the decision of whether or not to use a Bloom filter. (check-in: 0fb2a4e08f user: drh tags: bloom-filter) | |
| 18:50 | Enhance the sqlite3SrcListAppendFromTerm() routine so that it sets the Parser error on an OOM, causing an earlier unwind of the stack. (check-in: fee4699252 user: drh tags: trunk) | |
| 16:15 | Merge the WhereClause fix from trunk (check-in: d325025677 user: drh tags: bloom-filter) | |
| 16:07 | In the WhereClause object, do not assume that all TERM_VIRTUAL terms appear at the end of the list, because that is no longer true. Instead, keep a separate nBase count that is the size of the list excluding the tail of virtual terms. Use nBase instead of nTerm when scanning terms that are not virtual. Add assert()s to validate correctness of WhereClause. (check-in: 6024682ca4 user: drh tags: trunk) | |

| 23:02 | For CLI, extensibility refinement and small steps toward embedability (check-in: ad9970bcb5 user: larrybr tags: cli_extension) | |
| 22:37 | Do not generate a Bloom filter if it cannot be used prior to the next seek, as that leads to a misleading EXPLAIN QUERY PLAN. (check-in: 2739ed5192 user: drh tags: bloom-filter) | |
|
2021-12-06
| ||
| 23:07 | Improved EXPLAIN QUERY PLAN output for Bloom filters. (check-in: 00070e1fff user: drh tags: bloom-filter) | |

| 19:11 | Merge trunk fixes into the bloom-filter branch. (check-in: edacf8034d user: drh tags: bloom-filter) | |

| 15:24 | Do not allow certain dangerous ".testctrl" commands in safe mode. (check-in: 080e72d119 user: drh tags: trunk) | |
| 15:08 | Fix SQLITE_TESTCTRL_IMPOSTER so that it is a harmless no-op if the schema parameter is invalid. (check-in: 2d9a45ab10 user: drh tags: trunk) | |
| 13:07 | Attempt to vary the size of Bloom filters based on an estimate of how many keys the filter will hold. (check-in: a7adcf6908 user: drh tags: bloom-filter) | |
|
2021-12-05
| ||
| 20:19 | Run as many Bloom filters as possible before index lookups. (check-in: 06f6fefd67 user: drh tags: bloom-filter) | |
| 00:45 | Try to run all Bloom filters before any Seeks. This gives a small performance gain on the Star-Schema Benchmark. (check-in: 5be2470f87 user: drh tags: bloom-filter) | |
|
2021-12-04
| ||
| 21:11 | Miscellaneous cleanup of the new Bloom-filter code. (check-in: 201b6dd875 user: drh tags: bloom-filter) | |

| 13:43 | First attempt to use Bloom filters to optimize star-schema queries. (check-in: 28161fba9b user: drh tags: bloom-filter) | |

| 19:27 | Extension interface tweaks in support of planned usage (check-in: ce2a91438a user: larrybr tags: cli_extension) | |
| 19:10 | Merge the sqlite3WhereBegin() simplification from trunk. (check-in: 41ba2dfdd3 user: drh tags: bloom-filter) | |
| 18:53 | Factor the noop-join-elimination optimization out of the sqlite3WhereBegin() routine and into a separate "no-inline" subroutine, in order to reduce the complexity of sqlite3WhereBegin() and thereby encourage C compilers to inline sqlite3WhereCodeOneLoopStart(). (check-in: 6225e9abcb user: drh tags: trunk) | |
| 16:02 | Merge recent trunk enhancements into the bloom-filter branch. (check-in: 11d97fb8be user: drh tags: bloom-filter) | |
| 15:48 | Fix exprAnalyze() after recent performance enhancements so that it is able to handle IF_NULL_ROW opcode correctly, again. (check-in: 8029e6bab5 user: drh tags: trunk) | |
| 14:57 | Fix unreachable branches resulting from prior optimizations. (check-in: f3d6853ee8 user: drh tags: trunk) | |

|
2021-12-02
| ||
| 20:30 | Make shell buildable, fix a potential leak-to-be (check-in: eab1e1af5b user: larrybr tags: cli_extension) | |
| 18:15 | Optimizations to exprAnalyze() and sqlite3WhereExprUsage() save about 1.5 million CPU cycles for speedtest1, and result in a smaller binary. (check-in: 1f2252e65d user: drh tags: trunk) | |
| 18:09 | Merge for CLI fix. (check-in: 98cf18611d user: larrybr tags: cli_extension) | |
| 14:28 | Move the TK_IS token so that it is adjacent to the TK_IN token, as this allows the C compiler to optimize better, resulting in a slightly smaller and faster executable. (check-in: 8832fa9088 user: drh tags: trunk) | |
| 14:16 | In the shell tool, avoid modifying internal data structures until after the arguments to ".open" have been parsed. (check-in: fcc509d325 user: dan tags: trunk) | |
| 13:45 | Remove an unnecessary branch from exprAnalyze(), resulting in a small performance gain. (check-in: 3312be1db3 user: drh tags: trunk) | |

|
2021-11-30
| ||
| 14:07 | In the automatic index generator logic, be more precise about when a partial automatic index is allowed in order to capture more cases where it is legal to use a partial automatic index. (check-in: 664b461bb5 user: drh tags: trunk) | |
|
2021-11-29
