| 00:07 | Minor enhancements to the TclKit download tool. (check-in: 75e31b1d56 user: mistachkin tags: trunk) | |

| ||
| 00:07 | The optimization of check-in [9b2879629c34fc0a] is incorrectly reasoned. The WHERE clause of the partial index might not be true if the table of the partial index is the right table of a left join. So disable the optimization in that case. Ticket [623eff57e76d45f6] (check-in: 3be19e1151 user: drh tags: trunk) | |
|
2019-11-02
| ||

| 13:45 | "STORED" is not actually a keyword. The parser looks for STORED as an ordinary identifier. (check-in: 167cd574d6 user: drh tags: trunk) | |
| 13:32 | In sqlite3GenerateIndexKey(), do not attempt to reuse column values from the previous index if the current index is a partial index as the partial index test may have changed those values. Ticket [a9efb42811fa41ee] (check-in: 17e9f65814 user: drh tags: trunk) | |

| 13:37 | Fix an fts3 assert() that could fail when operating on a database containing corrupt records. (check-in: 7c52f5478f user: dan tags: trunk) | |
