| 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) | |
| 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) | |
| 17:05 | Fix a problem with resizing the wal-index mapping after the mapping has been extended by an external process. (check-in: 79d356fe user: dan 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) | |
| 02:13 | The first 6 WAL tests now work. It's a start. (check-in: a92c1851 user: drh tags: wal) | |

| 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) | |
| 14:58 | Close all open database connections at the end of wal.test. (check-in: 3cc55a75 user: dan tags: wal) | |
| 14:51 | Fix a bug in the WAL checkpoint code causing SQLite to use an inconsistent cache in a subsequent transaction. (check-in: d1cadeed user: dan tags: wal) | |
| 08:47 | Add tests to walthread.test. (check-in: 9e891e75 user: dan tags: wal) | |
|

| ||
| 18:17 | Add a test to walthread.test for changing between WAL and rollback modes. (check-in: da229e44 user: dan tags: wal) | |
| 17:49 | Merge two "wal" leaves. (check-in: 13d2d5a6 user: dan tags: wal) | |
| 17:48 | Change walthread.test so that tests can be run with either multiple threads or multiple processes. (check-in: 25f85f68 user: dan tags: wal) | |
| 17:21 | Changes to the interface design for the xShmLock method of the VFS. (check-in: 348409de user: drh tags: wal) | |
| 14:42 | Rename the sqlite3_log_hook() to sqlite3_wal_hook(). Added comments to wal.h. (check-in: bbc38511 user: drh tags: wal) | |

| 18:49 | Merge two "wal" leaves. (check-in: 8c2d43ba user: dan tags: wal) | |
| 18:43 | Add a test to check that a checkpointer releases its locks before returning, even if it has been prevented by a conflicting lock from checkpointing the database. (check-in: be44349d user: dan tags: wal) | |
| 14:37 | Fix a problem with identifying a corrupt database in WAL mode. (check-in: c8658da4 user: dan tags: wal) | |
| 11:49 | Add the xShmRelease() method to the VFS. The os_unix.c implementation of the shared memory logic is still non-functional. (check-in: ed715b47 user: drh tags: wal) | |
| 06:49 | Run trans.test and avtrans.test as part of the "wal" permutation. (check-in: c8893310 user: dan tags: wal) | |
| 05:42 | Fix a problem that occurs when one process causes the log-summary file to grow and then a second process attempts to read the database. (check-in: b51a5f8b user: dan tags: wal) | |
| 01:56 | Merge in recent changes from the trunk (check-in: 7a0ac682 user: drh tags: wal) | |
