19:29 | For sqlite3_win32_is_nt(), assume WinRT is NT-based and revise #ifdef ordering to prefer the ANSI version of GetVersionEx, when available. (check-in: be0a037244 user: mistachkin tags: trunk) | |
18:21 | Tweak the documentation for SQLITE_LIMIT_WORKER_THREADS. No changes to executable code. (check-in: 672e7387b1 user: drh tags: trunk) | |
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.
