| 11:33 | Fix a typo in the walmode.test test script introducted yesterday. check-in: dcabc90c user: drh tags: wal | |
| 11:19 | Fix the sqlite3_mutex_alloc() interface to return NULL (not segfault) when operating in threadsafe mode. (This is a general-purpose bug fix which really ought to be ported to trunk.) check-in: 64840a3c user: drh tags: wal | |
| 08:30 | Add test case demonstrating deadlock during recovery of very large log files. No fix yet. check-in: 63ea318e user: dan tags: wal | |
| 00:59 | Do not allow journal_mode=WAL if the underlying VFS does not support xShmOpen. check-in: d1fcccec user: drh tags: wal | |

| 22:28 | Merge in changes from the trunk. check-in: 76bf0eee user: drh tags: wal | |
| 21:03 | Avoid assertion faults in queries using indices with redundant columns. Ticket [3dbdcdb14e7f41]. check-in: 946e06cd user: drh tags: trunk | |
| 17:47 | Change the SHM VFS logic in os_unix.c so that it does not hold an exclusive lock n the mapped memory when also holding a CHECKPOINT lock. This improves concurrency between readers and checkpointers. check-in: 8660cda6 user: drh tags: wal | |
| 17:28 | Remove some obsolete debugging parameters. check-in: a012aed4 user: drh tags: wal | |

| 16:50 | Fix a problem with calculating the required size of the wal-index when appending frames. check-in: 9526b111 user: dan tags: wal | |
| 16:48 | In the debugging output for SHM-LOCK in os_unix.c, use symbolic names for the lock states rather than raw numbers. check-in: 2afc33de user: drh tags: wal | |
| 16:41 | Fix a problem in the previous commit. Both unixShm.lockState and unixShm.readLock should be set to READ when downgrading from a WRITE to a READ lock check-in: 90119fec user: dan tags: wal | |
| 16:38 | Fix a bug whereby upgrading from a READ_FULL to a WRITE lock, and then back to a read lock was dropping all WAL locks. check-in: 55f5af5e user: dan tags: wal | |
| 16:24 | Reapply commits [837d82a929] and [c05e7dca17] that were accidentally overwritten. check-in: 598de527 user: dan tags: wal | |
| 16:19 | Add xShmXXX() methods to the test VFS in test_devsym.test. check-in: 1d203424 user: dan tags: wal | |
| 16:12 | Correctly record the fact that the SHM lock reached PENDING if it did so but failed to reach CHECKPOINT. check-in: d9250e84 user: drh tags: wal | |
| 15:54 | Fix a couple uninitialized variables in the xShmLock method of the unix VFS. Improved debugging logic for xShmLock. check-in: 69567c5f user: drh tags: wal | |
| 15:49 | When closing a WAL connection, attempt an exclusive lock on the database file. If the lock is obtained, checkpoint the database and delete the wal and wal-index files. check-in: c05e7dca user: dan tags: wal | |
| 15:24 | If a reader attempts to upgrade to a writer, but is not reading the most recent database snapshot, return SQLITE_BUSY. check-in: 837d82a9 user: dan tags: wal | |
| 14:39 | Separate the concepts of underlying storage size and mapped size in the VFS shared-memory implementation. check-in: 4cbe49f1 user: drh tags: wal | |
| 11:43 | Add a missing walIndexUnmap() call to the checkpoint code. Change a couple of SQLITE_CANTOPEN constants to SQLITE_CANTOPEN_BKPT. check-in: 1f9e8c5c user: dan tags: wal | |
| 10:24 | Fix an assert() in sqlite3WalRead(). check-in: 2e7a0050 user: dan tags: wal | |
| 10:06 | Add missing mutexes to unixShmClose(). check-in: a4741cb5 user: dan tags: wal | |
| 09:52 | Fix a couple of assert() statements in os_unix.c and wal.c. Combine sqlite3WalIsDirty() with sqlite3WalUndo(). check-in: a8f958be user: dan tags: wal | |
| 09:32 | Add a missing walIndexUnmap() to sqlite3WalSnapshotOpen(). check-in: 72b95fde user: dan tags: wal | |
| 06:02 | Merge latest bugfix into wal branch. check-in: 265e66e6 user: dan tags: wal | |
| 05:57 | Zero the "immediate FK constraint counter" associated with a statement object when sqlite3_reset() is called. Fix for [c39ff61c43]. check-in: f660be61 user: dan tags: trunk | |

| 22:34 | Refactor wal.c to use the VFS. This check-in compiles and links and works ok as long as you leave WAL turned off, but WAL does not work. check-in: 62db5fa3 user: drh tags: wal | |
| 16:40 | Untested implementation of the shared-memory dead-man-switch. check-in: 70661128 user: drh tags: wal | |
| 15:17 | Progress towards a VFS that will support WAL. Locking code is in place but is untested. Still no support for the DMS. check-in: 1bde41cf user: drh tags: wal | |

| 14:37 | Fix a problem with identifying a corrupt database in WAL mode. check-in: c8658da4 user: dan tags: wal | |

| 19:17 | Optimization: Convert an ORDER BY clause into a no-op if the query also contains a GROUP BY clause that will force the same output order. check-in: ca9d86ba user: drh tags: trunk | |
| 17:42 | Do not attempt to set journal_mode=wal on :memory: or temp file databases. check-in: 30d01344 user: dan tags: wal | |

| 16:57 | Fixes for problems with small caches and SAVEPOINT rollback in WAL mode. check-in: 6a944f02 user: dan tags: wal | |
| 16:47 | Further enhancements to the showdb utility: A page number followed by "b" causes a btree decoding to occur on the page. check-in: 2ff824e5 user: drh tags: trunk | |
| 15:44 | Enhancements to the showdb.c utility program. Automatically detect the page size and adjust the display accordingly. Add the "dbheader" display option. check-in: 23eb408b user: drh tags: trunk | |
| 12:39 | Add the "wal" permutation to run existing test files savepoint.test and savepoint2.test in WAL mode. check-in: 205e5d8a user: dan tags: wal | |
| 10:40 | Add mutexes to fix a race condition in wal.c. This isn't a very good fix. check-in: 3d159939 user: dan tags: wal | |
| 00:19 | Change the names of the log.c and log.h source files to wal.c and wal.h. check-in: 56fe5d76 user: drh tags: wal | |
| 00:04 | Begin moving WAL-specific I/O into the VFS. This checkin contains VFS infrastructure but it is untested and is not yet hooked up to the WAL. The version number is bumped to 3.7.0 because of the VFS extension. check-in: f5e615c2 user: drh tags: wal | |
