| 17:50 | When the block sorting optimization is used in a scalar subquery, be sure to exit the loop as soon as the first valid output row is received. Fix for ticket [cb3aa0641d9a4]. (check-in: cdbb0947 user: drh tags: trunk) | |
|
2014-09-01
| ||
| 17:36 | Add support for using separate worker threads to speed large sorts. The SQLITE_MAX_WORKER_THREADS and SQLITE_DEFAULT_WORKER_THREADS compile-time options and the SQLITE_LIMIT_WORKER_THREADS argument to sqlite3_limit() and the "PRAGMA threads=N" pragma are added. (check-in: b1c0f0bc user: drh tags: trunk) | |
|
2014-08-30
| ||
| 15:49 | In the command-line shell, added options --lookaside, --pagecache, and --scratch used to configure auxiliary memories. (check-in: f61db04b user: drh tags: trunk) | |
|
2014-08-29
| ||
| 19:06 | Disable worker threads when SQLITE_THREADSAFE=0. Set the default compile-time maximum number of worker threads to 8 and honor the SQLITE_DEFAULT_WORKER_THREADS compile-time constant (which defaults to 0). (Closed-Leaf check-in: 33fa0410 user: drh tags: threads) | |
| 18:06 | Fix the speedtest1.c test program to set the worker thread count using the threads pragma. (check-in: 2ab4b5ad user: drh tags: threads) | |
| 14:40 | Merge recent performance enhancements from trunk onto the threads branch. (check-in: 35c44a3c user: drh tags: threads) | |
| 14:20 | Not a fault after all, rather a testing mistake. Move this change back to trunk. Was: Avoid an unnecessary OP_Move operation for expression subqueries. (check-in: 2a74129a user: drh tags: trunk) | |
| 12:29 | Contains a fault. Was: Avoid an unnecessary OP_Move operation for expression subqueries. (Closed-Leaf check-in: 462f42af user: drh tags: mistake) | |
|
2014-08-28
| ||
| 19:38 | Improved WHERETRACE messages for the estimated output row reductions from range scans. (check-in: fdd478bb user: drh tags: trunk) | |
