| ||
| 19:57 | Add the SQLITE_MAX_WORKER_THREADS compile time option. And the SQLITE_CONFIG_WORKER_THREADS sqlite3_config() switch. (check-in: 2774710d user: dan tags: threads) | |
| 16:53 | • Edit [83a105c864247a02|83a105c8]: Move to branch threads-closed. (artifact: b3cbb445 user: dan) | |
| 16:53 | • Edit [83a105c864247a02|83a105c8]: Mark "Closed". Add tag "threads-closed". (artifact: a4ca9392 user: dan) | |

| 19:48 | Changes to make the multi-threaded sorter sort stably. (Closed-Leaf check-in: 83a105c8 user: dan tags: threads-closed) | |

| 09:34 | Fix a problem in vdbesort.c causing spurious SQLITE_NOMEM errors when using memsys3 or memsys5. (check-in: a683c05f user: dan tags: threads) | |
| 06:27 | Add the optimization to avoid some unnecessary calls to sqlite3VdbeRecordUnpack() added to the trunk by [707ea170b3]. (check-in: fc4d04e6 user: dan tags: threads) | |
|
2014-03-28
| ||

|
2014-03-27

| 19:25 | Instead of allocating a single large buffer at the beginning of each sort operation, start with a small buffer and extend it using realloc() as required. (check-in: 81987c8c user: dan tags: orderby-planning) | |
