| 15:57 | For SQLITE_ENABLE_PREUPDATE_HOOK builds, disable the optimization for a REPLACE command on a WITHOUT ROWID table with no indexes, triggers or foreign key constraints that causes SQLite to clobber any existing row without separately checking for it. This optimization causes SQLite to omit the expected pre-update-hook callbacks. (check-in: 6281ef974c user: dan tags: trunk) | |
|
2019-01-06

| 19:46 | Merge changes from begin-concurrent-wal2. Also modify the unix-excl shm-locks on this branch so that it is not an error to attempt to release an EXCLUSIVE lock that is not held. (check-in: 86685679b4 user: dan tags: begin-concurrent-pnu-wal2) | |
| 17:08 | Reinstate assert() statements in os_unix.c that were removed to allow wal-mode SHARED locks to be taken over more than one locking slot (this branch no longer does that, so the assert() statements can go back in). (check-in: fcb7348ba1 user: dan tags: begin-concurrent-wal2) | |
| 17:00 | Reinstate assert() statements in os_unix.c that were removed to allow wal-mode SHARED locks to be taken over more than one locking slot (this branch no longer does that, so the assert() statements can go back in). (check-in: 8445fb6d5d user: dan tags: wal2) | |

| 21:43 | Fix harmless compiler warnings. (check-in: b57c545a38 user: drh tags: trunk) | |
| 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: e130319317 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| 20:13 | Remove an optimization that can no longer occur, being superceded by the subquery-reuse optimization.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: 4fcdc7a293 user: drh tags: reuse-subqueries) | |
| 18:30 | Merge enhancements and bug fixes from trunk. (check-in: 9fb646f29c user: drh tags: reuse-subqueries) | |
| 17:58 | Small changes to the OP_OpenEphemeral opcode to improve testability. (check-in: f856676c84 user: drh tags: trunk) | |
| 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: 4678cb1044 user: drh tags: trunk) | |

| 14:23 | Additional small performance increase and size reduction to the sqlite3VdbeMakeLabel() mechanism. (check-in: 1bdee199a7 user: drh tags: trunk) | |
| 02:26 | A new implementation of sqlite3VdbeMakeLabel() is faster and makes fewer memory allocations by deferring memory allocation until sqlite3VdbeResolveLabel() is called, at which point the code generator has a better idea of how big the relocation table needs to be. The sqlite3VdbeMakeLabel() routine now takes a Parse* parameter instead of Vdbe*. (check-in: 4a0929ac76 user: drh tags: trunk) | |
