| 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: 2afc33de2b 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: 90119fecbc 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: 55f5af5e17 user: dan tags: wal) | |
| 16:24 | Reapply commits [837d82a929] and [c05e7dca17] that were accidentally overwritten. (check-in: 598de52700 user: dan tags: wal) | |
| 16:19 | Add xShmXXX() methods to the test VFS in test_devsym.test. (check-in: 1d20342424 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: d9250e84ac 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: 69567c5fca 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: c05e7dca17 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: 837d82a929 user: dan tags: wal) | |
| 14:39 | Separate the concepts of underlying storage size and mapped size in the VFS shared-memory implementation. (check-in: 4cbe49f13f 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: 1f9e8c5c27 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: f660be615a user: dan tags: trunk) | |
| 02:13 | The first 6 WAL tests now work. It's a start. (check-in: a92c1851da 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: 62db5fa3b6 user: drh tags: wal) | |
| 16:40 | Untested implementation of the shared-memory dead-man-switch. (check-in: 706611283e 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: 1bde41cf08 user: drh tags: wal) | |
| 14:58 | Close all open database connections at the end of wal.test. (check-in: 3cc55a7568 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: d1cadeed4e user: dan tags: wal) | |
| 08:47 | Add tests to walthread.test. (check-in: 9e891e7543 user: dan tags: wal) | |

| 18:17 | Add a test to walthread.test for changing between WAL and rollback modes. (check-in: da229e44bd user: dan tags: wal) | |
| 17:49 | Merge two "wal" leaves. (check-in: 13d2d5a66e user: dan tags: wal) | |
| 17:48 | Change walthread.test so that tests can be run with either multiple threads or multiple processes. (check-in: 25f85f6872 user: dan tags: wal) | |
| 17:21 | Changes to the interface design for the xShmLock method of the VFS. (check-in: 348409de26 user: drh tags: wal) | |
| 14:42 | Rename the sqlite3_log_hook() to sqlite3_wal_hook(). Added comments to wal.h. (check-in: bbc385111b user: drh tags: wal) | |

| 18:49 | Merge two "wal" leaves. (check-in: 8c2d43babd 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: be44349d2b user: dan tags: wal) | |
| 14:37 | Fix a problem with identifying a corrupt database in WAL mode. (check-in: c8658da446 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: ed715b47c5 user: drh tags: wal) | |
| 06:49 | Run trans.test and avtrans.test as part of the "wal" permutation. (check-in: c889331051 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: b51a5f8bc6 user: dan tags: wal) | |
| 01:56 | Merge in recent changes from the trunk (check-in: 7a0ac682c3 user: drh 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: ca9d86baf7 user: drh tags: trunk) | |
| 17:42 | Do not attempt to set journal_mode=wal on :memory: or temp file databases. (check-in: 30d0134454 user: dan tags: wal) | |
| 17:36 | Change the default_cache_size pragma to always store a positive value. (check-in: 36fb2cae75 user: drh tags: trunk) | |
| 17:30 | Identify the SQLite version meta-value entry in the db-header output of showdb. (check-in: 245d934b72 user: drh tags: trunk) | |
| 16:57 | Fixes for problems with small caches and SAVEPOINT rollback in WAL mode. (check-in: 6a944f028d 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: 2ff824e58c 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: 23eb408b5d 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: 205e5d8ac0 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: 3d159939cc 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: 56fe5d7624 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: f5e615c28c user: drh tags: wal) | |
