| 15:53 | Updated header comments in wal.c. No functional code changes. check-in: 687632a6 user: drh tags: trunk | |
| 15:23 | Add a busy-handler to a test case in walthread.test to prevent errors. check-in: d3d348aa user: dan tags: trunk | |
| 13:49 | Modify walcrash2.test so that it works with DEFAULT_AUTOVACUUM=1. check-in: 77438882 user: dan tags: trunk | |
| 13:40 | Update header comments in wal.c to correctly describe the WAL file format. Update the locking region offsets in os_unix.c and os_win.c and add assert() statement to verify that the locking region offsets are correct. check-in: 40030c07 user: drh tags: trunk | |
| 10:50 | If a writer exits unexpectedly in the middle of a transaction, have the following writer remove any wal-index hash-table entries left by the interrupted transaction. check-in: ed77556a user: dan tags: trunk | |
| 02:24 | Remove unreachable code associated with WAL from the pager. check-in: 54c1718e user: drh tags: trunk | |

| 17:00 | Fix the wal2.test script so that it works in auto_vacuum mode. check-in: 6a818afb user: drh tags: trunk | |
| 13:57 | Change the checksum used in WAL files so that each frames checksum depends on the content of the WAL header and all frame headers and content up to and including the frame to which the checksum is attached. check-in: 8a53f12c user: dan tags: trunk | |
| 13:28 | Make sure a WAL frame of all zeros is detected as an invalid frame. check-in: 02d99ad4 user: drh tags: trunk | |

| 10:39 | Change the WAL file format to support two kinds of checksums - one that is fast to calculate on little-endian architectures and another that is fast on big-endian architectures. A flag in the wal-header indicates which the file uses. check-in: 65ba804d user: dan tags: trunk | |
|
2010-05-22
| ||
| 08:22 | Add a couple of missing methods to test_osinst.c.. check-in: 5c9e9c06 user: dan tags: trunk | |

2010-05-21
| ||
| 19:15 | Fix another bug in walClearHash(). check-in: 40f80ffe user: dan tags: trunk | |

| 13:16 | Fix the wal-index header read routine so that it correctly detects a zero header as being malformed and in need of a wal-index rebuild. check-in: 1a4eb3a3 user: drh tags: trunk | |
|
2010-05-20
| ||

|
2010-05-19
| ||

| 19:39 | Add the SQLITE_FCNTL_SIZE_HINT to the os_win.c VFS. check-in: 9894118d user: drh tags: trunk | |

|
2010-05-18
| ||

| 18:01 | Refactoring of the WalIterator implementation. check-in: b5b60fdc user: drh tags: trunk | |

| 12:56 | Comment clarifications in wal.c. check-in: a029be10 user: drh tags: trunk | |
| 12:37 | Keep additional state information in the pager in an effort to reduce the number of SQLITE_FCNTL_SIZE_HINTs. (Note: This change was found to make no performance difference and so has been moved onto a side branch. Use the parent check-in instead of this one.) Closed-Leaf check-in: 97d88a86 user: drh tags: branch-3.6.1-exp | |
|
2010-05-17
| ||

| 15:52 | An improvement to the SQLITE_FCNTL_SIZE_HINT change that invokes the hint less often and only when really needed. check-in: a1d20ceb user: drh tags: branch-3.6.1 | |
| 15:33 | Invoke the SQLITE_FCNTL_SIZE_HINT opcode on the sqlite3_file_control() interface for database files before extending the size of the file. The VFS can use this hint to preallocate space. check-in: 9a083711 user: drh tags: branch-3.6.1 | |
|
2010-05-15
| ||
| 10:24 | Add a note to the documentation of sqlite3_wal_hook() to say not to return SQLITE_ROW or SQLITE_DONE. Or any other value that is not a valid SQLite error code. check-in: 2f0b6cbf user: dan tags: trunk | |

|
2010-05-14
| ||
| 20:15 | Fix a typo that (by bad luck) was not a syntax error but which caused some important lines of code to be skipped when SQLITE_DEBUG was not used. check-in: 9ef99d97 user: drh tags: trunk | |
| 19:24 | Make sure the value of an INTEGER PRIMARY KEY column supplied to triggers and especially to FK constraints really contains the ROWID and not the NULL that is stored in the column itself. Ticket [dd08e5a988d00dec]. check-in: 636f8609 user: drh tags: trunk | |
| 16:34 | Pull in all the latest changes from the trunk. Update the win32 SHM methods to work with the new interface design. Closed-Leaf check-in: 4b69f2cd user: drh tags: wal-win32 | |

|
2010-05-12
| ||
| 19:02 | (Moved to the mistake branch due to compile errors in test_osinst.c.) Change the vfs instrumentation code in test_osinst.c to make it easier to deploy. Add a vtab implementation for reading the binary log file format. check-in: ee13c884 user: dan tags: mistake | |

2010-05-07
| ||
| 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: be114bdf 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: a65c2939 user: drh tags: trunk | |
| 18:23 | Additional tweaks to API documentation. No functional code changes. check-in: e1230782 user: drh tags: trunk | |

| 09:43 | Test another IO error case in wal.c. check-in: 8b3b5ab8 user: dan tags: trunk | |
| 06:59 | Fix a problem with checkpointing large log files created by an external process. check-in: 8f94bde5 user: dan tags: trunk | |
| 05:46 | Since walIndexTryHdr() can no longer encounter any error conditions, change tehe function signature so that it does not return an error code. This removes unreachable branches from other code. check-in: 061a282c user: dan tags: trunk | |
| 00:28 | Another attempt to fix permutations.test so that it excludes WAL tests from the journaltest permutation. check-in: 58c40442 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: 811b45a9 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: c3520460 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: c1762dda 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: bb0b6021 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: dc98ee16 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: 637f51dd 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: d0c0034b 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: 56a17dae user: drh tags: trunk | |
