02:10 | Remove an incorrect ALWAYS() macro. Fix for ticket [e5c6268dd807fa8950] - a problem introduced in SQLite 3.9.0 and found by libFuzzer. (check-in: 824ad96f72 user: drh tags: trunk) | |
01:17 | Add a clarifying comment to the virtual table test module 'test8'. (check-in: e92f97a679 user: mistachkin tags: trunk) | |
00:49 | Do not try to eliminate No-ops at the end of VDBE program as this can cause problems for some DISTINCT handling algorithms, and does not improve performance. This also fixes an assertion fault found by libFuzzer. (check-in: 19d9f9ce69 user: drh tags: trunk) | |
