| 20:39 | Attempt to optimize "x IS NULL" and "x IS NOT NULL" expressions when x is a column with a NOT NULL constraint. This addresses the performance issue described by forum post a5fc33cf9d8f4ff5. (check-in: de9c86c9 user: dan tags: trunk) | |
| 20:14 | Attempt to optimize "x IS NULL" and "x IS NOT NULL" expressions when x is a column with a NOT NULL constraint. (Closed-Leaf check-in: 5ecd8425 user: dan tags: ifnull-opt) | |

| 16:40 | When a sub-transaction is released, if no pages required by containing sub-transactions were journaled, truncate the statement journal.

| 15:53 | Allow WHERE terms to be pushed down into sub-queries that contain window functions, provided that the WHERE term is made up of entirely of constants and copies of expressions found in the PARTITION BY clauses of all window functions in the sub-query. (check-in: 20689468 user: dan tags: trunk) | |
| 15:36 | Further tests for the push-down optimization with window functions. (Closed-Leaf check-in: 4b089f70 user: dan tags: window-functions-pushdown) | |

| 18:02 | Update sqlite3changeset_apply_v2() so that it handles no-op UPDATE changes (UPDATE changes that modify no columns). This fixes a regression introduced by [e4ccfac09b]. Also modify sqlite3rebaser_rebase() so that it does not output changesets containing such UPDATEs. (check-in: 0288a801 user: dan tags: trunk) | |
