| 03:42 | Improvement to a comment. No changes to code. (Closed-Leaf check-in: 486949fc03 user: drh tags: readonly-wal-recovery) | |
|
2017-11-13
| ||
| 05:51 | Remove some branches in walTryBeginRead() that were added by check-in [ce5d13c2de] but became unreachable with the addition of logic in check-in [18b26843] that enabled read-only clients to parse the WAL file into a heap-memory WAL-index, thus guaranteeing that the WAL-index header is always available. (check-in: 9c6b38b9a9 user: drh tags: readonly-wal-recovery) | |
|
2017-11-11
| ||
| 20:11 | In wal.c: improved comments, new assert() and testcase() macros, and replace some magic numbers with appropriate symbolic constants. (check-in: 13ec8a77a4 user: drh tags: readonly-wal-recovery) | |

| 20:02 | Get read-only SHM file tests passing on Win32. (check-in: abef053535 user: mistachkin tags: readonly-wal-recovery) | |
| 18:53 | Further corrections to read-only SHM file handling on Win32. (check-in: 43c311701b user: mistachkin tags: readonly-wal-recovery) | |
| 18:21 | Corrections to Win32 lock detection for SHM files. (check-in: 3a91be975d user: mistachkin tags: readonly-wal-recovery) | |

|
2017-11-08
| ||
| 19:26 | Extra comments on the sqlite3OsShmMap() call in walBeginUnlocked(). No changes to code. (check-in: 033ee92bf4 user: drh tags: readonly-wal-recovery) | |
| 17:51 | Turns out that SQLITE_READONLY_CANTLOCK is an historical name that must be preserved. So make a new SQLITE_READLOCK_CANTINIT name instead. (check-in: 04974a8b5c user: drh tags: readonly-wal-recovery) | |
| 17:32 | Change the name of SQLITE_READONLY_CANTLOCK to SQLITE_READONLY_CANTINIT. (check-in: 6d7f94faa7 user: drh tags: readonly-wal-recovery) | |
|
2017-11-07
| ||
| 21:25 | Update an assert in wal.c. (check-in: 94527b897b user: dan tags: readonly-wal-recovery) | |
| 21:15 | Handle the race condition that may occur if another process connects and then checkpoints and truncates the wal file while a readonly-shm client is building its heap-memory wal-index. (check-in: 5a6703fc3f user: dan tags: readonly-wal-recovery) | |
| 15:43 | On unix, if the *-shm file cannot be opened for read/write access, open it read-only and proceed as if the readonly_shm=1 URI option were specified. (check-in: ba718754fa user: dan tags: readonly-wal-recovery) | |
| 09:08 | Add fault-injection tests for the code on this branch. (check-in: a7d949fb73 user: dan tags: readonly-wal-recovery) | |
|
2017-11-06
| ||
| 19:49 | Add further test cases for the new code on this branch. And a couple of fixes. (check-in: 71af9acb22 user: dan tags: readonly-wal-recovery) | |
|
2017-11-04
| ||
| 21:06 | Add further tests for the code added on this branch. (check-in: a6716fcde3 user: dan tags: readonly-wal-recovery) | |
| 18:10 | In cases where a readonly_shm client cannot take the DMS lock on the *-shm file, have it parse the wal file and create a wal-index to access it in heap memory. (check-in: 18b268433d user: dan tags: readonly-wal-recovery) | |
|
2017-11-03
| ||
| 17:17 | Allow readonly_shm connections to access the *-shm file using read() even if it is unable to take a DMS lock. (check-in: 9b0d5c4ff7 user: dan tags: fcntl_shm_read) | |
|
2017-11-02
| ||
| 18:57 | Fix test cases in wal2.test broken by the locking change in the previous commit. (check-in: f569c35172 user: dan tags: readonly-wal-recovery) | |
| 11:12 | Avoid locking shm-lock WAL_READ_LOCK(0) during recovery. Doing this allows recovery to proceed while a readonly_shm connection in unlocked mode has an ongoing read transaction. (check-in: 5190d84a29 user: dan tags: readonly-wal-recovery) | |
|
2017-11-01
| ||
| 20:59 | If a readonly_shm connection cannot map the *-shm file because no other process is holding the DMS lock, have it read from the database file only, ignoring any content in the wal file. (check-in: ce5d13c2de user: dan tags: readonly-wal-recovery) | |
| 19:50 | Make sure the JSON1 extension is available to sqlite3_checker.exe (check-in: a946a8ed46 user: drh tags: trunk) | |
| 19:44 | Add the checkindex.c extension and the sqlite3_checker utility program used for doing live validation of large databases. (check-in: 0c5d18a01e user: drh tags: trunk) | |
| 19:22 | Adjust page numbers in the ext/repair/test/checkfreelist01.test module due to the fact that the pending-byte page is no longer shifted down to a low-numbered page but is in its rightful place. (Closed-Leaf check-in: c1641affae user: drh tags: checkindex) | |
| 18:31 | Add the "sqlite3_imposter DB SCHEMA ROOT SQL" command to sqlite3_checker. Use it to fix the checkindex01.test module. There are still errors reported by the checkfreelist01.test module. (check-in: 0593a2ba74 user: drh tags: checkindex) | |
| 18:05 | Move the test scripts for checkfreelist and checkindex over into the ext/repair/test directory. Run them now using the sqlite3_checker utility with the --test option. Some tests are currently failing due to an incomplete port. This is an incremental check-in. (check-in: 17f8d5e111 user: drh tags: checkindex) | |
| 13:09 | Minor cleanup in checkindex.c. Add progress displays when checking a single index in the top-level TCL script for sqlite3_checker. (check-in: 3ca31cc3ff user: drh tags: checkindex) | |
| 07:06 | Merge latest trunk changes into this branch. (check-in: 985bfc9929 user: dan tags: readonly-wal-recovery) | |
| 01:05 | When sqlite3_checker finds a problem, show the row key as part of the error message, not the row index number. (check-in: 6ffe917d10 user: drh tags: checkindex) | |
| 01:01 | Actually perform index checks when running sqlite3_checker (check-in: 5453002026 user: drh tags: checkindex) | |
| 00:10 | Begin putting functionality into the sqlite3_checker binary. (check-in: e82e883b93 user: drh tags: checkindex) | |
|
2017-10-31
| ||
| 18:15 | Merge all recent enhancements from trunk. (check-in: 24adf90ffb user: drh tags: checkindex) | |
| 14:56 | Update the built procedures for the sqlite3_analyzer utility to allow it to be linked with an external sqlite3.o library. Automatically detect a missing dbstat extension and report the compile-time error. (check-in: bb39744f4b user: drh tags: trunk) | |
| 12:20 | Fix redundancies in the makefiles that resulted from moving shell.c over to shell.c.in. (check-in: bf09fa683e user: drh tags: trunk) | |
| 12:06 | Fix a minor comment typo. No changes to code. (check-in: 5f79e6d9c3 user: drh tags: trunk) | |
| 03:40 | Remove unnecessary NEVER() and ALWAYS() conditionals. (check-in: 1c80c75d4b user: drh tags: trunk) | |
|
2017-10-30
| ||
| 23:25 | Add the showshm utility program for printing out the shm header in a human-readable format. (check-in: f6304fd142 user: drh tags: trunk) | |
| 20:44 | Clarify some comments describing the WAL index file. No changes to code. (check-in: 3be3aad9ec user: drh tags: trunk) | |
| 18:49 | Improve the performance of the LIKE operator by using strcspn() to aid wildcard matching. (check-in: 37284d4e8f user: drh tags: trunk) | |
| 18:26 | Speed up wildcard searches in LIKE using strchr() (Closed-Leaf check-in: 4d336d7420 user: drh tags: like-compare-opt) | |
|
2017-10-28
| ||
| 20:54 | Increase the version number for the next release - which is still months away but there have been significant query planner enhancements since the previous release. (check-in: 457eedfac0 user: drh tags: trunk) | |
| 20:51 | Reactivate query flattening when the result set of the outer query has no function calls or subqueries. This is a partial reversal of check-in [c9104b59]. Co-routines are still preferred if the outer query has a complex result set, but for simple results sets, query flattening is used. Check-in [4464f40ccd7] is completely backed out due to this change. (check-in: d17ef7d153 user: drh tags: trunk) | |
| 12:20 | Add test cases from OSSFuzz to prevent a regression in co-routine processing. (check-in: 689743d8e3 user: drh tags: trunk) | |
|
2017-10-27
| ||
| 23:28 | I was a little concerned about this check-in. Though I could not generate a failure myself, I thought it was risky. I checked it in for further testing. Then, overnight, OSSFuzz found a failure case for me. So the change is now moved out into a deadend branch. Was: Use OP_SCopy rather than OP_Copy to transfer results from a co-routine to its consumer. This undoes an earlier fix for ticket [98825a79ce] by check-in [ec6a06246e] because that problem no longer occurs due to WHERE clause push-down. (Closed-Leaf check-in: 0926df095f user: drh tags: mistake) | |
| 18:24 | Fix a Pager ref-count leak in the sqlite_dbpage virtual table. (check-in: c063bb04da user: drh tags: trunk) | |
