| 14:45 | Changes to make WAL more robust against SHM locking failures and OOM errors. (check-in: ebf4041383 user: drh tags: trunk) | |
| 14:43 | In the rowhash.test, make sure global variables are cleared prior to use. (check-in: 28efe0a404 user: drh tags: trunk) | |
| 12:58 | Undo one of the "const" markers from the previous check-in because the value needs to be changable, even if it is not actually ever changed in the current implementation. (check-in: c24ac3563f user: drh tags: trunk) | |
| 05:53 | Add some 'const' markers to static data that is really constant. (check-in: e7073e23b8 user: dan tags: trunk) | |

| 21:02 | The shared-memory used by WAL on linux now really is shared memory in /dev/shm. On other unix flavors, the file is in a temporary directory rather than in the same directory as the database. (check-in: fc18c4aadb user: drh tags: trunk) | |
| 19:15 | Changes to the way faults are injected into xShmXXX VFS calls. (check-in: 716d99f392 user: dan tags: trunk) | |
| 17:46 | Change the OOM and IO error test cases in walfault.test so that each test case runs both types of error simulation. (check-in: b627e15368 user: dan tags: trunk) | |
| 15:44 | Delay the decision to restart the log file until data is actually ready to be written to the log file (instead of at the start of a write transaction). (check-in: b1abfaaf53 user: dan tags: trunk) | |
| 15:24 | The incremental checkpoint feature is not perfect yet, but it is working well enough to merge it into the trunk. (check-in: 1d3e569e59 user: drh tags: trunk) | |
| 14:30 | Merge with [15abbc3416]. (Closed-Leaf check-in: f4b9003a2d user: dan tags: wal-incr-ckpt) | |
| 14:12 | If an attempt to get a read-lock on the WAL fails with SQLITE_BUSY_RECOVER, call the busy-handler at the btree level. (check-in: ce64496509 user: dan tags: wal-incr-ckpt) | |
| 13:17 | Fix a bug introduced by the previous check-in but only seen if SQLITE_ENABLE_EXPENSIVE_ASSERTS is turned on. (check-in: 9c9ec8994b user: drh tags: wal-incr-ckpt) | |
| 12:58 | Fix an off-by-one boundary-value issue in walCleanupHash(). (check-in: f039552e63 user: drh tags: wal-incr-ckpt) | |
| 11:08 | Do not hold the shared-memory mutex in os_unix.c if returning NULL. (check-in: 9622dd468c user: dan tags: wal-incr-ckpt) | |
| 10:44 | If the checkpoint fails to obtain an exclusive lock on one of the read-lock bytes, do not consider this an error. (check-in: 9e95e35728 user: dan tags: wal-incr-ckpt) | |
| 07:51 | Fixes to the test cases in wal2.test. (check-in: cd5fbcbce8 user: dan tags: wal-incr-ckpt) | |
| 01:08 | Comment edits and cleanup in wal.c. No functional code changes. (check-in: e8e666ab82 user: drh tags: wal-incr-ckpt) | |
| 00:28 | Attempt to get the filectrl.test script running. (check-in: e46a8f2b75 user: drh tags: wal-incr-ckpt) | |
| 00:03 | Fix os_unix.c so that it will compile and build on a Mac. (check-in: bc707c83e5 user: drh tags: wal-incr-ckpt) | |
|

| ||
| 20:28 | Fix issues with locking_mode=EXCLUSIVE in WAL. (check-in: 8deba0cebd user: drh tags: wal-incr-ckpt) | |
| 18:24 | Add an "isInit" field in the wal-index header that must be non-zero for a valid header. Use this to detect an uninitialized wal-index. (check-in: a16fde1901 user: drh tags: wal-incr-ckpt) | |
| 16:56 | Fix an inconsistent #ifdef in wal.c. Fix os_unix.c so that it does not allow moving an SHM lock directly exclusive to shared without going through unlocked. (check-in: 552658da28 user: drh tags: wal-incr-ckpt) | |
| 16:41 | Avoid dropping the checkpoint lock after a recovery run as a precursor to a checkpoint operation. (check-in: cc25cfa046 user: dan tags: wal-incr-ckpt) | |
| 16:17 | Zero the checkpoint header as the last step of successful WAL recovery. Avoid an unnecessary lock/unlock in WalBeginReadTransaction. (check-in: db3509c55d user: dan tags: wal-incr-ckpt) | |
| 16:10 | Get the new xShmLock interface design working on os_win.c. (check-in: 149a7082e2 user: drh tags: wal-incr-ckpt) | |
| 14:39 | Make sure WAL alway requests enough shared-memory space. (check-in: 138f128317 user: drh tags: wal-incr-ckpt) | |
| 14:28 | Remove the tests that enable tracing based on the existance of the "vdbe_*" files when in SQLITE_DEBUG mode. (check-in: cdbb4e7ca7 user: drh tags: wal-incr-ckpt) | |
| 14:18 | Update another test case in wal.test. (check-in: 99fde69e61 user: dan tags: wal-incr-ckpt) | |
| 13:11 | Change WAL test cases to account for the improved concurrency in the new checkpoint logic. (check-in: 2d6f248505 user: drh tags: wal-incr-ckpt) | |
| 12:30 | Do not fail a checkpoint just because active readers prevent backfill. (check-in: 9aa4243e0c user: drh tags: wal-incr-ckpt) | |
| 12:15 | Add WALTRACE() macros to help with debugging and analysis. (check-in: 765c33181a user: drh tags: wal-incr-ckpt) | |
| 12:02 | Another minor fix to checkpoint on the WAL branch. (check-in: 853f1e3f77 user: dan tags: wal-incr-ckpt) | |
| 11:39 | Fix a bug in checkpoint introduced by [181ceb32ea]. (check-in: b499dbc88a user: dan tags: wal-incr-ckpt) | |
| 11:16 | Fix some asserts and other things in the new WAL branch. (check-in: 181ceb32ea user: dan tags: wal-incr-ckpt) | |
| 06:38 | Changes to the way one of the WAL/OOM tests works. (check-in: 15abbc3416 user: dan tags: trunk) | |
| 01:41 | WAL runs but quickly deadlocks. (check-in: ace58acbf1 user: drh tags: wal-incr-ckpt) | |
|

| 19:55 | Initial code for incremental checkpoint in WAL mode. This check-in compiles on unix and runs as long as you do not engage WAL mode. WAL mode crashes and burns. Consider this check-in a baseline implementation for getting the new capability up and running. (check-in: ef3ba7a17f user: drh tags: wal-incr-ckpt) | |
|
2010-05-29
| ||
| 08:40 | Add tests to fkey2.test to check that ON CONFLICT clauses do not affect SQLite's behaviour when an FK constraint is violated. (check-in: e9e5b10019 user: dan tags: trunk) | |
| 06:18 | Minor changes to checksum related test cases. (check-in: 60c22bde52 user: dan tags: trunk) | |
|
2010-05-28
| ||
| 11:16 | Add a test to walcksum.test to stress the checksum calculation. (check-in: 778d0c1768 user: dan tags: trunk) | |
|
2010-05-26
| ||
| 17:31 | Make sure the wal-index mapping is always large enough to cover the entire active area of the wal-index. (check-in: 42705babba user: drh tags: trunk) | |
| 15:06 | Change the semantics of xShmGet() such that it will never increase the size of shared memory. xShmSize() must be used to grow the size of shared memory. A shared memory segment size cannot be shrunk (except by dropping it). (check-in: 72de007312 user: drh tags: trunk) | |
|
2010-05-25
| ||
| 15:53 | Updated header comments in wal.c. No functional code changes. (check-in: 687632a6b3 user: drh tags: trunk) | |
| 15:23 | Add a busy-handler to a test case in walthread.test to prevent errors. (check-in: d3d348aa97 user: dan tags: trunk) | |
| 13:49 | Modify walcrash2.test so that it works with DEFAULT_AUTOVACUUM=1. (check-in: 77438882dd 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: 40030c0739 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: ed77556adc user: dan tags: trunk) | |
| 02:24 | Remove unreachable code associated with WAL from the pager. (check-in: 54c1718e6d user: drh tags: trunk) | |
|

| 20:27 | OOM errors during an auto-checkpoint are benign. (check-in: 3d252ce5d0 user: drh tags: trunk) | |
