| 18:30 | Fix for the test_devsym.c test module for the VFS-SHM refactoring. (check-in: 49d6293375 user: drh tags: wal-refactor) | |
| 18:10 | A couple simple fixes to get wal.test mostly working. (check-in: c744581274 user: drh tags: wal-refactor) | |
| 18:01 | Refactoring the VFS-SHM methods used by WAL. This version compiles and runs non-WAL test cases but crashes and burns on wal.test. (check-in: 2b00152c1a user: drh tags: wal-refactor) | |
| 17:14 | Updates to WAL support in os_win.c: pulled in latest changes from src/os_unix.c; updated tracing; misc. improvements. (check-in: 76504726a1 user: shaneh tags: wal-win32) | |
| 13:50 | Remove the OP_Variable optimization of check-in [48b77b04935d894] since it can lead to malfunctions as described in ticket [26ff0c82d1e90]. (check-in: 7838163d08 user: drh tags: trunk) | |

| 14:46 | Modify the format of the wal-index to use a hash table to index log file segments. (check-in: 40b0a6357b user: dan tags: trunk) | |
| 14:10 | If an ATTACH command fails due to OP_JournalMode but still attaches the database, make sure VACUUM still detaches it when done. (check-in: 6ecdc7ba2b user: drh tags: trunk) | |
| 11:20 | Enhance the OP_JournalMode opcode with an ignore-errors option and use that option the ATTACH command. (check-in: 0bdea4cfbd user: drh tags: trunk) | |

| 20:34 | When running a checkpoint while in locking_mode=EXCLUSIVE, be sure to move the wal-index lock to UNLOCK from READ prior to promoting to CHECKPOINT. (check-in: be114bdf9b user: drh tags: trunk) | |
| 20:02 | Change the xShmOpen() method of the VFS to take the database file name as its argument, not the WAL file name. Also fix some unrelated compiler warnings. (check-in: a65c293926 user: drh tags: trunk) | |
| 18:23 | Additional tweaks to API documentation. No functional code changes. (check-in: e1230782a3 user: drh tags: trunk) | |
| 13:57 | Updates to documentation on the C interfaces supporting WAL. No functional changes to code. (check-in: 681ba20cf0 user: drh tags: trunk) | |
| 13:52 | Fix a recently introduced problem in wal.test. (check-in: 79b52d0ff7 user: dan tags: trunk) | |

| 00:28 | Another attempt to fix permutations.test so that it excludes WAL tests from the journaltest permutation. (check-in: 58c404429c user: drh tags: trunk) | |
|
2010-05-06

| 22:21 | Remove savepoint6.test from the set of tests run by journaltest since savepoint6.test uses journal_mode=WAL. (check-in: 811b45a96b user: drh tags: trunk) | |
| 21:37 | The PRAGMA journal_mode=WAL; command now makes WAL the default journal mode for new databases added with ATTACH, so the behavior is consistent with the other journal modes. (check-in: c3520460a4 user: drh tags: trunk) | |
| 20:19 | Make sure to do a clean shutdown of the library upon existing the shell in order to remove WAL files. (check-in: c1762dda00 user: drh tags: trunk) | |

| 19:04 | Updates to the VFS SHM locking documentation. (check-in: 9927ce4210 user: drh tags: trunk) | |
| 18:48 | Instead of transitioning to RECOVER state from CHECKPOINT when a recovery is required, perform the recovery while holding the CHECKPOINT lock. (check-in: bb0b6021e7 user: dan tags: trunk) | |
| 18:27 | If recovery is run before a checkpoint, change back to a CHECKPOINT lock before performing the actual checkpoint. (check-in: dc98ee169c user: dan tags: trunk) | |
| 18:04 | Only pass -1 as the size parameter to xShmGet when the caller does not care what size mapping is returned. Only call xShmSize when the underlying allocation (not the mapping) should be resized. (check-in: 637f51ddf9 user: dan tags: trunk) | |
| 17:28 | Fix a bug whereby an old snapshot could be checkpointed (and subsequent transactions discarded) if the last connection to disconnect from a WAL database happended to be holding an out-of-date wal-index header. (check-in: d0c0034b0b user: dan tags: trunk) | |
| 16:06 | After throwing an error to say that one cannot change into WAL mode within a tranactions, do not then go and change into WAL mode. (check-in: 56a17dae91 user: drh tags: trunk) | |

| 20:00 | Change the behavior of the sqlite3_wal_hook() callback. It should now return SQLITE_OK or an error code and the error code is propagated back up the stack. If a checkpoint is desired, the callback should invoke sqlite3_wal_callback() itself. (check-in: 1b14195e05 user: drh tags: trunk) | |
| 19:09 | Further simplifications to the SHM locking logic. Remove the SQLITE_SHM_QUERY option. Unify the WRITE to READ and RECOVER to READ transitions. (check-in: e9bfa6e4ce user: drh tags: trunk) | |
| 19:04 | Test the handling of errors returned by the xShmXXX() APIs. (check-in: 72663123d6 user: dan tags: trunk) | |
| 18:46 | Do not compare page sizes on source and destination of backup until transactions are started and the page sizes are locked. This is a fix to check-in [7bd44794c4]. (check-in: ec7157788b user: drh tags: trunk) | |
| 18:20 | Simplifications to the SHM locking implementation in os_unix.c. (check-in: 9de05bfb09 user: drh tags: trunk) | |
| 16:23 | Prohibit backup if the destination is using WAL and has a different page size from the source. (check-in: 7bd44794c4 user: drh tags: trunk) | |
| 15:33 | When closing a WAL database, if the exclusive lock on the database file is obtained and the database successfully checkpointed, delete the wal-index file from the file system. (check-in: 2ac5d96c8e user: dan tags: trunk) | |
| 04:11 | Make sure the page size of the main database is fixed following a failed VACUUM attempt. Otherwise, two consecutive failed VACUUM attempts with attempted page_size changes on encrypted or WAL databases could result in database corruption. (check-in: 208e7d5d3a user: drh tags: trunk) | |
| 03:39 | Do not attempt to modify the page_size when running VACUUM on a WAL database. (check-in: 58a1a59be8 user: drh tags: trunk) | |
| 00:22 | Get the previous mutex fix working with SQLITE_DEBUG and with the amalgamation. (check-in: df19928f7e user: drh tags: trunk) | |
| 00:05 | When the in single-threaded mode, the sqlite3_mutex_alloc() interface still returns a non-NULL value. The mutex doesn't do anything, but it tests non-NULL. This way, extensions (or VFSes) that use sqlite3_mutex_alloc() can tell the difference between an OOM error and mutexes being disabled. (check-in: 451fd17575 user: drh tags: trunk) | |

| 19:17 | Fix a bug in the computation of the current time for the alternative CURRENT_TIMESTAMP functions used when SQLITE_OMIT_DATETIME is defined. (check-in: e7ded46b5e user: drh tags: trunk) | |
| 18:51 | Documentation stubs for sqlite3_wal_autocheckpoint and sqlite3_wal_checkpoint. (check-in: 313762427d user: drh tags: trunk) | |
| 18:22 | Fix a bug in the xCurrentTime() method of the os_unix.c VFS. (check-in: 551df11a56 user: drh tags: trunk) | |

| 16:36 | Update the crash-test VFS in test6.c to pass-through the shared-memory methods to the real underlying VFS. This fixes the walcrash.test script. (check-in: ea09ff3791 user: drh tags: trunk) | |
| 16:30 | Change the VFS definition so that all methods take a VFS object pointer as their first parameter. (check-in: 43b5b07f0d user: drh tags: trunk) | |
| 15:58 | Have sqlite3_wal_checkpoint() handle a zero-length string in the same way as a NULL pointer. Fix "PRAGMA wal_checkpoint" so that it checkpoints all attached databases. (check-in: 7fecd21f45 user: dan tags: trunk) | |
| 14:32 | Use VFS method xCurrentTimeInt64 instead of xCurrentTime when it is available. Provide an implementation of xCurrentTimeInt64 for os_unix.c. (check-in: ab77b3ae6d user: drh tags: trunk) | |
| 14:08 | Merge the write-ahead-logging changes into the trunk. (check-in: de9ae443cc user: drh tags: trunk) | |
