7 check-ins related to "mutex-free-pcache"
2011-01-18
| ||
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: e5ca59e63b user: drh tags: trunk) | |
16:13 | Get all test cases working with the mutex-free-pcache implementation. (Closed-Leaf check-in: 2dc98d2999 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: f1cf02efcb user: drh tags: mutex-free-pcache) | |

21:32 | Here is a completely new implementation of the mutex-free-pcache. This one uses a common code base and automatically selects whether or not to use mutexes depending on compile-time and start-time options. (check-in: d094a1bfb7 user: drh tags: mutex-free-pcache) | |
18:30 | Fix a typo in the documentation for sqlite3_stmt_readonly(). (check-in: 56417a3386 user: drh tags: trunk) | |

16:12 | Provide an alternative and experimental pcache implementation that avoids the use of mutexes at the expense of using more memory. (Closed-Leaf check-in: 2ea5bd1287 user: drh tags: mutex-free-pcache) | |
15:17 | Fix comments, including some documentation comments, in the page cache logic. No code changes. (check-in: c80e9c1a0d user: drh tags: trunk) | |
