Split part of "PRAGMA ota_mode" off into "PRAGMA pager_ota_mode". This allows some specialized custom VFS implementations to intercept and implement the expected pager-related effects of this pragma. (check-in: 209f672e user: dan tags: ota-update)
08:25
Add a command line program that uses the extension. This serves as example code and is also useful for performance testing. (check-in: ffa1524e user: dan tags: ota-update)

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)
2014-08-29
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)

22:43
Merge the CAST operator enhancements from trunk. (check-in: 6c8f86e4 user: drh tags: threads)

16:43
Rework the way trees of MergeEngine objects are built in vdbesort.c to make it easier to follow. Fix memory leaks that could follow an OOM or IO error. Add various comments to explain functions in vdbesort.c. (check-in: 69026ec7 user: dan tags: threads)
2014-04-15
20:52
Fix some problems to do with OOM conditions in vdbesort.c. Some problems remain. (check-in: 2f94f9ce user: dan tags: threads)

18:41
Improve performance in single-threaded mode by having the final merge pass keys directly to the VDBE, instead of going via a final PMA. (Closed-Leaf check-in: 02610cd9 user: dan tags: threads-experimental)
