| 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) | |
|
2010-05-30
| ||
| 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) | |
| 20:24 | Remove the walmode.test case from the inmemory_journal test of permutations.test. (check-in: 27ba9c21fb user: drh tags: trunk) | |
| 17:00 | Fix the wal2.test script so that it works in auto_vacuum mode. (check-in: 6a818afb93 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: 8a53f12c83 user: dan tags: trunk) | |
| 13:28 | Make sure a WAL frame of all zeros is detected as an invalid frame. (check-in: 02d99ad4b5 user: drh tags: trunk) | |
| 12:34 | Fix up test_osinst.c to work with SQLITE_OMIT_VIRTUALTABLE. (check-in: 51fd38152b 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: 65ba804dd1 user: dan tags: trunk) | |
|
2010-05-22
| ||
| 08:22 | Add a couple of missing methods to test_osinst.c.. (check-in: 5c9e9c06ae user: dan tags: trunk) | |
| 00:55 | Add several EXPENSIVE_ASSERT code blocks to validate the wal-index hash table. Fix the bugs that these code blocks fine. Rename walClearHash() to walCleanupHash() and simplify its interface. (check-in: 7aade899e5 user: drh tags: trunk) | |
|
2010-05-21
| ||
| 19:15 | Fix another bug in walClearHash(). (check-in: 40f80ffe70 user: dan tags: trunk) | |
| 18:24 | Comment out the SQLITE_FCNTL_SIZE_HINT from os_unix.c since it does not seem to provide any performance gain there. (check-in: 7d01309da6 user: drh tags: trunk) | |
| 16:23 | Correct an off-by-one bug in the previous commit. (check-in: 75a1130d86 user: dan tags: trunk) | |
| 15:31 | Remove entries from wal-index hash tables when a rollback or savepoint rollback occurs. (check-in: 36795c2b23 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: 1a4eb3a3ef user: drh tags: trunk) | |
|
2010-05-20
| ||
| 23:51 | Add a new xShmBarrier method to the VFS - a shared-memory fence operation. Implement the same in both unix and win32. Use it to make the WAL subsystem more robust. (check-in: 1bd011c9fe user: drh tags: trunk) | |
| 21:21 | Make use of the extra information in the WAL header and frame header to enhance robustness. (check-in: 9580ecb7e3 user: drh tags: trunk) | |
| 16:45 | Convert the wal-header and frame-header to 24 bytes. Extra information in both headers is designed to enhance robustness after crashes, though the extra information is currently unused. This is a snapshot of a work in progress. (check-in: 669706431f user: drh tags: trunk) | |
|
2010-05-19
| ||
| 23:41 | Merge WIN32 WAL support into trunk. Still some issues with locking to resolve. (check-in: 43377663fc user: shaneh tags: trunk) | |
| 22:09 | Cherry-pick the SQLITE_FCNTL_SIZE_HINT patch (check-in [2b7e3b4a30d6a7c4a8] and bump the version number to 3.6.23.2. (check-in: 776679af58 user: drh tags: branch-3.6.23) | |
| 20:30 | Disable the corruptE test which SQLITE_OVERSIZE_CELL_CHECK is enabled. This is a cherrypick merge from check-in [1dc4f9fe9b83467ba]. (check-in: a40d080ca3 user: drh tags: branch-3.6.23) | |
| 19:39 | Add the SQLITE_FCNTL_SIZE_HINT to the os_win.c VFS. (check-in: 9894118d20 user: drh tags: trunk) | |
| 19:26 | Add the SQLITE_FCNTL_SIZE_HINT operator to sqlite3_file_control() and use it to give the VFS hints about the ultimate size of a database file when the file is growing. (check-in: 2b7e3b4a30 user: drh tags: trunk) | |
| 19:09 | Fix a bug in the new checkpoint computation. Also update the checkpoint algorithm in the test scripts to align with the new implementation. (check-in: 8b6056f2ee user: drh tags: trunk) | |
| 18:08 | Revise the checksumming algorithm in wal.c. More variable refactoring. (check-in: 542b90eba6 user: drh tags: trunk) | |
| 17:49 | Refactoring some variable names in wal.c. (check-in: 1d201ff51f user: drh tags: trunk) | |
| 01:53 | Add a large comment to wal.c describing the WAL and wal-index file formats. (check-in: a71a22b52f user: drh tags: trunk) | |
|
2010-05-18
| ||
| 23:29 | Update the wal-index hash format so that hash-table space is reused following a rollback, thus preventing hash table overflows. Add assert()s to verify that hash tables do not overfill. Further refactoring of the wal-index code. (check-in: ada9a8c7b6 user: drh tags: trunk) | |
