Merge branches branch-3.7.2 and stat3-enhancement into a new branch for testing purposes. check-in: 0df04f920b user: drh tags: stat3-3.7.2
13:16
Merge the stat3-enhancement branch with trunk, but keep the resulting merge in a separate branch for now. check-in: 63f2c7859f user: drh tags: stat3-trunk

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: eaf447ea87 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: 3fe5d54f63 user: drh tags: stat3-enhancement
01:10
Fix an error with OOM processing in the ANALYZE logic. check-in: b26ec79c69 user: drh tags: stat3-enhancement

Fix a few harmless compiler warnings. Add SQLITE_ENABLE_STAT3 to the standard compiler warning script. check-in: 3d68f9afee 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: 9650d79628 user: drh tags: stat3-enhancement
01:15
Add the analyze8.test test module for sqlite_stat3. check-in: 2c83ac89dc user: drh tags: stat3-enhancement

Update some test cases to work with sqlite_stat3 instead of sqlite_stat2. check-in: 2504bcfb0c user: drh tags: stat3-enhancement
12:02
Fix a couple of typos in comments in analyze.c. check-in: ae31dc67aa user: dan tags: stat3-enhancement

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: 89b2f70884 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: 1dcd24283e 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: 8225924ea0 user: drh tags: stat3-enhancement

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: 52e1d7e8dd user: drh tags: stat3-enhancement

Make the openDirectory routine in os_unix.c overrideable so that it can be turned into a harmless no-op for the chromium sandbox. check-in: 6b236069e1 user: drh tags: trunk
