| 04:19 | Specifying an invalid mutex implementation (via SQLITE_CONFIG_MUTEX) should cause the default one to be used instead. (check-in: 1a97bc81 user: mistachkin tags: mutexInitCmpSwap) | |
| 03:40 | Clarify the new mutex implementation reset logic in sqlite3_shutdown(). (check-in: f9a03483 user: mistachkin tags: mutexInitCmpSwap) | |
| 03:35 | Add more asserts to the mutex subsystem. (check-in: 7562f1fb user: mistachkin tags: mutexInitCmpSwap) | |
