|20:39||Additional steps to help ensure that scalar subqueries are only evaluated once even if they are used in multiple places within the query. This fixes a performance regression reported on the mailing list and caused by check-in [531eca6104e41e43] which was a fix for ticket [787fa716be3a7f650c]. Think of this check-in as an improved fix for that ticket. (check-in: e1303193 user: drh tags: trunk)|
|20:13||Remove an optimization that can no longer occur, being superceded by the subquery-reuse optimization. Put an assert in place of the optimization to detect if the need for this optimization ever returns. (Closed-Leaf check-in: 4fcdc7a2 user: drh tags: reuse-subqueries)|
|18:30||Merge enhancements and bug fixes from trunk. (check-in: 9fb646f2 user: drh tags: reuse-subqueries)|

|16:36||Fix the OP_OpenEphemeral opcode in the bytecode engine so that if it is called a second or subsequent time, it merely clears the existing table rather than creating a new one. Proposed fix for ticket [d0866b26f83e9c55e30de0821f5d]. (check-in: 4678cb10 user: drh tags: trunk)|
