2017-02-23
02:15
Add two NEVER() operators in the sqlite3BtreeRowCountEst() routine. (check-in: 7a959f6d user: drh tags: auto-analyze)
00:58
Do a single OP_Expire at the very end of "PRAGMA optimize", and omit the OP_Expire on ANALYZE commands invoked by the pragma. (check-in: 188300a3 user: drh tags: auto-analyze)
2017-02-22
20:24
Change the name of the analyze_as_needed pragma to "optimize". Enhance the comment (which will become documentation, assuming these changes land on trunk) to explain that the optimize pragma is likely to be enhanced in various ways in future releases and that applications should not depend upon the current behavior. (check-in: 9fced545 user: drh tags: auto-analyze)
19:49
Merge integrity_check and other improvements from trunk. (check-in: fe073905 user: drh tags: auto-analyze)
19:41
Move a branch condition in analyze.c inside an #ifdef SQLITE_ENABLE_STAT4 block. (check-in: d6afd98d user: dan tags: trunk)
19:27
Improve the performance of ANALYZE when SQLITE_ENABLE_STAT4 is defined. (check-in: 737a8244 user: dan tags: trunk)
18:53
Improvements to PRAGMA integrity_check. Verify CHECK constraints. Verify NOT NULL constraints even on table that lack indexes. Verify CHECK and NOT NULL constraints with PRAGMA quick_check. (check-in: aa02bd3c user: drh tags: trunk)
18:04
Cleanup and simplification of the output row count limit control of PRAGMA integrity_check. (Closed-Leaf check-in: 5af7d72e user: drh tags: integrity-check-improvements)
15:11
Fix integrity_check so that it verifies NOT NULL constraints even for tables that have no indexes. Enhance quick_check so that it verifies NOT NULL and CHECK constraints. (check-in: 5264844b user: drh tags: integrity-check-improvements)
14:15
Enhance "PRAGMA integrity_check" so that it verifies CHECK constraints. (check-in: 549bae08 user: drh tags: integrity-check-improvements)
2017-02-21
21:24
In sqlite3VdbeHalt(), return as soon as possible if Vdbe.magic!=VDBE_MAGIC_RUN. This makes sqlite3_reset() slightly faster in some cases. (check-in: 80adc0cb user: dan tags: trunk)
