|
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: 9c6b38b9 user: drh tags: readonly-wal-recovery) | |
|
2017-11-11
| ||

| 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: ba718754 user: dan tags: readonly-wal-recovery) | |
| 09:08 | Add fault-injection tests for the code on this branch. (check-in: a7d949fb 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: 18b26843 user: dan tags: readonly-wal-recovery) | |
| 08:53 | Fix an LSM problem with read-only connections and compression (not compression-factory) callbacks. (check-in: 51ee5188 user: dan tags: trunk) | |

| 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: 5190d84a 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: ce5d13c2 user: dan tags: readonly-wal-recovery) | |

| 19:30 | Fix the SQLITE_NoopUpdate #define so that it occurs under the correct conditions. (check-in: bdf791f9 user: drh tags: begin-concurrent-pnu) | |
| 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: c1641aff user: drh tags: checkindex) | |
| 18:48 | The "PRAGMA noop_update" command now requires SQLITE_ENABLE_NOOP_UPDATE and no longer requires SQLITE_DEBUG. (check-in: 81baf67c user: drh tags: begin-concurrent-pnu) | |
| 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: 0593a2ba 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.

| 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: 6ffe917d user: drh tags: checkindex) | |
| 01:01 | Actually perform index checks when running sqlite3_checker (check-in: 54530020 user: drh tags: checkindex) | |
| 00:10 | Begin putting functionality into the sqlite3_checker binary. (check-in: e82e883b 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: bb39744f user: drh tags: trunk) | |
| 12:20 | Fix redundancies in the makefiles that resulted from moving shell.c over to shell.c.in. (check-in: bf09fa68 user: drh tags: trunk) | |
| 12:06 | Fix a minor comment typo. No changes to code. (check-in: 5f79e6d9 user: drh tags: trunk) | |

| 23:25 | Add the showshm utility program for printing out the shm header in a human-readable format. (check-in: f6304fd1 user: drh tags: trunk) | |
| 20:44 | Clarify some comments describing the WAL index file. No changes to code. (check-in: 3be3aad9 user: drh tags: trunk) | |
| 19:38 | Add support for indexes on expressions to incremental_index_check. (check-in: 8c1c701f user: dan tags: checkindex) | |
| 18:49 | Improve the performance of the LIKE operator by using strcspn() to aid wildcard matching. (check-in: 37284d4e user: drh tags: trunk) | |
| 18:26 | Speed up wildcard searches in LIKE using strchr() (Closed-Leaf check-in: 4d336d74 user: drh tags: like-compare-opt) | |
| 17:05 | In checkindex.c, use C code instead of SQL/group_concat() to compose various SQL clauses. This is to make it easier to support indexes on expressions. (check-in: 940606b3 user: dan tags: checkindex) | |
| 08:04 | Fix an issue in incremental_index_check with indexes that use non-default collation sequences. (check-in: 3ebb2351 user: dan tags: checkindex) | |
|
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: 457eedfa 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: d17ef7d1 user: drh tags: trunk) | |
| 20:31 | Fix "after" parameter handling in the incremental_index_check code. (check-in: c40c3c62 user: dan tags: checkindex) | |
| 12:20 | Add test cases from OSSFuzz to prevent a regression in co-routine processing. (check-in: 689743d8 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: 0926df09 user: drh tags: mistake) | |
| 20:53 | Add the start of the "incremental_index_check" virtual table in ext/repair/checkindex.c. For incremental verification of index contents. (check-in: d5b9dada user: dan tags: checkindex) | |
| 18:24 | Fix a Pager ref-count leak in the sqlite_dbpage virtual table. (check-in: c063bb04 user: drh tags: trunk) | |
| 17:09 | Handle the Ctrl-C event for the shell on Win32. (check-in: c8aaf371 user: mistachkin tags: trunk) | |
| 12:27 | Additional test case demonstrating the ability to access structure elements using quoted names in the JSON1 extension. (check-in: 8d3cc928 user: drh tags: trunk) | |
|
2017-10-26
| ||
| 20:04 | Enhance the min/max optimization so that it works with indexes on expressions. (check-in: 6caec908 user: drh tags: trunk) | |
