| 19:42 | Remove unused code and fix comments. Final cleanup before merging. (Closed-Leaf check-in: ce42039f user: drh tags: bloom-filter) | |
| 18:44 | Enable bloom filters for the right table of a LEFT JOIN. Fix unreachable branches. (check-in: d342ab72 user: drh tags: bloom-filter) | |
| 16:17 | Add ".mode off" and ".mode count" to the CLI. (check-in: b11f4d08 user: drh tags: bloom-filter) | |
| 04:45 | Closer to passing all Tcl tests (with an odd failure) (check-in: 6956e989 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: 88b43d79 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: 0fb2a4e0 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: fee46992 user: drh tags: trunk) | |
| 16:15 | Merge the WhereClause fix from trunk (check-in: d3250256 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: 6024682c user: drh tags: trunk) | |

| 23:02 | For CLI, extensibility refinement and small steps toward embedability (check-in: ad9970bc 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: 2739ed51 user: drh tags: bloom-filter) | |
|
2021-12-06
| ||
| 23:07 | Improved EXPLAIN QUERY PLAN output for Bloom filters. (check-in: 00070e1f user: drh tags: bloom-filter) | |

| 19:11 | Merge trunk fixes into the bloom-filter branch. (check-in: edacf803 user: drh tags: bloom-filter) | |

| 15:40 | Do not allow SQLITE_LIMIT_LENGTH to be set lower than 1 as an SQLITE_LIMIT_LENGTH of 0 causes lots of unnecessary problems for users of the sqlite3_str object. (check-in: 8fd5b8ec user: drh tags: trunk) | |
| 15:24 | Do not allow certain dangerous ".testctrl" commands in safe mode. (check-in: 080e72d1 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: 2d9a45ab 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: a7adcf69 user: drh tags: bloom-filter) | |
|
2021-12-05
| ||
| 20:19 | Run as many Bloom filters as possible before index lookups. (check-in: 06f6fefd 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: 5be2470f user: drh tags: bloom-filter) | |
|
2021-12-04
| ||
| 21:11 | Miscellaneous cleanup of the new Bloom-filter code. (check-in: 201b6dd8 user: drh tags: bloom-filter) | |
| 18:45 | Add VdbeCoverage() macros. Adjust the Bloom-filter hash function so that it correctly deals with zero-blobs. (check-in: 629ee2e3 user: drh tags: bloom-filter) | |
| 18:40 | Add design doc for shell extensibility (check-in: 96b8ffb0 user: larrybr tags: cli_extension) | |

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

| 19:27 | Extension interface tweaks in support of planned usage (check-in: ce2a9143 user: larrybr tags: cli_extension) | |
| 19:10 | Merge the sqlite3WhereBegin() simplification from trunk. (check-in: 41ba2dfd 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: 6225e9ab user: drh tags: trunk) | |
| 16:02 | Merge recent trunk enhancements into the bloom-filter branch. (check-in: 11d97fb8 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: 8029e6ba user: drh tags: trunk) | |
| 14:57 | Fix unreachable branches resulting from prior optimizations. (check-in: f3d6853e user: drh tags: trunk) | |

|
2021-12-02
| ||
| 20:30 | Make shell buildable, fix a potential leak-to-be (check-in: eab1e1af 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: 1f2252e6 user: drh tags: trunk) | |
| 18:09 | Merge for CLI fix. (check-in: 98cf1861 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: 8832fa90 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: fcc509d3 user: dan tags: trunk) | |
| 13:45 | Remove an unnecessary branch from exprAnalyze(), resulting in a small performance gain. (check-in: 3312be1d user: drh tags: trunk) | |
| 12:55 | Small performance optimization in sqlite3WhereClauseClear(). (check-in: 080b35e6 user: drh tags: trunk) | |

|
2021-11-29
| ||
| 18:09 | Merge in the proposed date/time function enhancements: (1) Add the unixepoch() function, (2) the 'auto' modifier and (3) the 'julianday' modifier. (check-in: 19c51b46 user: drh tags: trunk) | |
