| 13:45 | Fix the stat3 analysis loader to be compatible with sqlite3_db_status(). Also fix some OOM issues with the stat3 analysis loader. (Closed-Leaf check-in: eaf447ea user: drh tags: stat3-enhancement) | |
| 02:51 | Fix a bug in the cleanup of stat tables on a DROP TABLE in autovacuum mode. (check-in: 3fe5d54f user: drh tags: stat3-enhancement) | |
| 01:10 | Fix an error with OOM processing in the ANALYZE logic. (check-in: b26ec79c user: drh tags: stat3-enhancement) | |

| 17:06 | Fix a few harmless compiler warnings. Add SQLITE_ENABLE_STAT3 to the standard compiler warning script. (check-in: 3d68f9af user: drh tags: stat3-enhancement) | |
| 02:07 | Allow the sqlite3VdbeJumpHere() routine to accept a negative or zero address if a prior memory allocation error has occurred. The new sqlite_stat3 logic needs this. (check-in: 9650d796 user: drh tags: stat3-enhancement) | |
| 01:15 | Add the analyze8.test test module for sqlite_stat3. (check-in: 2c83ac89 user: drh tags: stat3-enhancement) | |

| 12:58 | Update some test cases to work with sqlite_stat3 instead of sqlite_stat2. (check-in: 2504bcfb user: drh tags: stat3-enhancement) | |
| 12:02 | Fix a couple of typos in comments in analyze.c. (check-in: ae31dc67 user: dan tags: stat3-enhancement) | |

| 19:35 | Further testing and bug fixing for sqlite_stat3. Added the Index.avgEq field to index statistics. Fixed several problems in the query planner associated with stat3. (check-in: 89b2f708 user: drh tags: stat3-enhancement) | |
| 15:25 | Add the sqlite_stat3.nDLT field. Use an linear congruence PRNG to choose which samples to select from among those with the same nEq field. (check-in: 1dcd2428 user: drh tags: stat3-enhancement) | |
| 00:58 | The ANALYZE command picks for 15 samples for sqlite_stat3 with the largest nEq fields, plus 5 other evenly spaced samples. (check-in: 8225924e user: drh tags: stat3-enhancement) | |

| 01:51 | Begin a branch that experimentally replaces sqlite_stat2 with a new table called sqlite_stat3 that will hopefully facilitate better query planning decisions. (check-in: 52e1d7e8 user: drh tags: stat3-enhancement) | |
