| 12:22 | Add test for the code that detects an inconsistent pair of wal-index headers to wal2.test. (check-in: 157feba10f user: dan tags: trunk) | |
| 11:56 | If an attempt to sync the database file as part of a checkpoint fails, do not update the shared "nBackfill" variable. Otherwise, another process could wrap the log and overwrite content before it is synced into the database. (check-in: b813233d76 user: dan tags: trunk) | |
| 10:37 | Fix a problem where an SQLITE_BUSY in the checkpoint code was being treated as an IO error (abandoning, instead of just limiting, the checkpoint). (check-in: 02c4040ce2 user: dan tags: trunk) | |
|
2010-06-03
| ||
| 19:10 | Fix another problem in test_vfs.c. (check-in: df7d59899c user: dan tags: trunk) | |
| 18:20 | Have test_vfs.c simulate IO errors in xShmLock. (check-in: fcbf7cf189 user: dan tags: trunk) | |
| 18:02 | Performance fix for winShmClose(). (check-in: ed7774de04 user: drh tags: trunk) | |
| 16:58 | Add extra tests for removing elements from wal-index hash tables as part of a rollback. (check-in: af3e598ad9 user: dan tags: trunk) | |
| 12:35 | Delay opening the sub-journal until SQLite actually needs to write data to it. (check-in: c43deb33ae user: dan tags: trunk) | |
| 12:09 | Remove global variables when compiled with SQLITE_OMIT_WSD (check-in: dd10a547f1 user: drh tags: trunk) | |
| 09:25 | Enhancements to test_vfs.c and walfault.test. (check-in: ac0de2f39e user: dan tags: trunk) | |
| 09:17 | If an error (OOM or SQLITE_FULL error) occurs while executing an SQL statement and a statement-transaction is automatically rolled back as a result, if a second error occurs during the statement rollback do a full transaction rollback instead. Otherwise the client can be left with an inconsistent cache. This can affect both WAL and rollback modes. (check-in: eb80ddc665 user: dan tags: trunk) | |
| 09:01 | If a malloc fails while allocating a savepoint object at the pager level, do not try to roll that savepoint back later on. (check-in: 91cb08ffb6 user: dan tags: trunk) | |
|

| 20:38 | When a lock fails due to an I/O error (not an SQLITE_BUSY) then the checkpoint should fail. (check-in: c6eb0a2727 user: drh tags: trunk) | |
| 18:59 | Fix a problem with rolling back to a savepoint opened before the writer decided to wrap the log file. (check-in: 6b4aed6aae user: dan tags: trunk) | |
| 17:15 | If an error occurs while writing frames to the log to commit a transaction, do not mark the pages as clean in the cache. Otherwise, the subsequent rollback does not roll them back (leaving the client to continue with a cache that makes it appear that the transaction was committed - inconsistent with the database on disk). (check-in: cb571c1b71 user: dan tags: trunk) | |
| 16:40 | Added implementation of vfslog_time() for Windows testing. (check-in: b3109f85bd user: shaneh tags: trunk) | |
| 16:39 | Updated wal2.test for windows testing. (check-in: c3606f3985 user: shaneh tags: trunk) | |
| 15:59 | Make sure the directory used by os_unix.c for shared-memory files is always the same, regardless of individual client permissions and environment variable settings. (check-in: f97bd520f0 user: drh tags: trunk) | |
| 15:43 | When walTryBeginRead() encounters an I/O error trying to set a lock (as opposed to SQLITE_BUSY) be sure to propagate that error back up the call stack. (check-in: aa2c2b67a7 user: drh tags: trunk) | |
| 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) | |
