| 21:25 | Add SQLITE_DBCONFIG options LEGACY_ALTER_TABLE, NO_DQS_SCHEMA, and NO_DQS. (check-in: 1fad2092 user: drh tags: new-dbconfig-options) | |
| 17:37 | Deprecate the SQLITE_ALLOW_COVERING_INDEX_SCAN compile-time option when it is turned off. This probably will impact no-one. If it does, they will get an error message instructing them to contact developers, so that we can get feedback that somebody is actually using this feature. Start-time disabling of covering index scan is not affected. (check-in: 23e49f99 user: drh tags: trunk) | |
| 13:25 | • Fixed ticket [f1580ba1]: Built-in RTRIM collating sequence yields incorrect comparisons plus 8 other changes (artifact: 71c96e66 user: drh) | |
| 13:24 | Fix the implementation of the built-in RTRIM collating sequence so that it works for control characters at the end of the string. Ticket [f1580ba1b574e9e9] (check-in: 86fa0087 user: drh tags: trunk) | |
| 12:29 | • Fixed ticket [ce8717f0]: LIKE malfunctions for UNIQUE COLLATE NOCASE column plus 6 other changes (artifact: 751df5f0 user: drh) | |
| 12:28 | Refactor the LIKE optimization decision logic so that it uses sqlite3AtoF() on both boundary keys to determine if the optimization can be used when the LHS is something that might not have TEXT affinity. Ticket [ce8717f0885af975]. See also [c94369cae9b561b1], [b043a54c3de54b28], [fd76310a5e843e07], and [158290c0abafde67]. (check-in: b4a9e09e user: drh tags: trunk) | |
| 11:03 | • New ticket [f1580ba1] Row is not fetched in WITHOUT ROWID table and a composite primary key. (artifact: 253e38a4 user: mrigger) | |
| 10:01 | • New ticket [ce8717f0] LIKE malfunctions for UNIQUE COLLATE NOCASE column. (artifact: 81eff856 user: mrigger) | |

| 19:06 | Fix problem with window functions min() and max() when used with a PARTITION clause and a frame starting point other than "UNBOUNDED PRECEDING". (check-in: 43eb1e75 user: dan tags: exp-window-functions) | |
| 14:30 | Merge latest trunk changes into this branch. (check-in: 5cf5f180 user: dan tags: exp-window-functions) | |
| 14:27 | Improve comments and code legibility in new file window.c. (check-in: bb915854 user: dan tags: exp-window-functions) | |

| 18:06 | Fix an error in the walfault.test script introduced by the previous check-in. (check-in: a2b9374f user: drh tags: trunk) | |
| 18:01 | Move the xShmMap method to in between xShmLock and xShmBarrier, since it seems to fit in there logically. (check-in: 58dfd83d user: drh tags: trunk) | |
| 17:09 | Merge the experimental shared-memory mmap-by-chunk changes into the trunk. (check-in: f295e7ed user: drh tags: trunk) | |
| 16:16 | Add the new xShmMap (formerly xShmPage) to os_win.c. (check-in: 13e7a824 user: dan tags: experimental) | |
| 14:07 | Remove xShmGet/Size/Release from the sqlite3_vfs structure. Change the name of xShmPage to xShmMap. Remove some code that is now unused from os_unix.c and some of the test VFS implementations. (check-in: fc0cabc1 user: dan tags: experimental) | |

| 11:18 | Change the interface to internal function walGetHash() to make it easier to follow. (check-in: 5e8e2e97 user: dan tags: experimental) | |
| 10:30 | Add the xShmPage method to the "crash" vfs in test6.c. (check-in: 1008f536 user: dan tags: experimental) | |
| 07:53 | Add some fault-injection tests to improve coverage. (check-in: 37b26d12 user: dan tags: experimental) | |
