| 17:03 | Do not use mutexes in the pcache implementation unless SQLITE_ENABLE_MEMORY_MANAGMENT is defined. This is a performance enhancement. A side effect is that pcaches will not steal pages from one another unless ENABLE_MEMORY_MANAGEMENT is set, or unless SQLITE_THREADSAFE=0. check-in: e5ca59e6 user: drh tags: trunk | |
| 16:13 | Get all test cases working with the mutex-free-pcache implementation. Closed-Leaf check-in: 2dc98d29 user: drh tags: mutex-free-pcache | |
| 15:17 | Do not use SQLITE_MUTEX_STATIC_MEM2 since it has been reused as STATIC_OPEN. Instead, create a new static mutex STATIC_PMEM which is an alias for the unused STATIC_LRU2. check-in: f1cf02ef user: drh tags: mutex-free-pcache | |
