| 18:57 | Performance improvement for GLOB and LIKE matching for patterns with two or more multi-character wildcards ("*" or "%"). (check-in: 2df0ebf95f user: drh tags: trunk) | |
| 18:49 | Faster version of patternCompare() that uses new return values rather than an extra parameter to communicate wildcard information back up to parent searches. (Closed-Leaf check-in: a1e2b6ce3a user: drh tags: pattern-compare-optimization) | |
| 17:34 | Modify the patternCompare() function (used for GLOB, LIKE) to better handle patterns containing multiple wildcard characters ("*", "%"). (check-in: c5e5614d98 user: dan tags: pattern-compare-optimization) | |

| 16:54 | Add the remember(V,PTR) extension function which copies an SQL value into an application variable. (check-in: d2d30914d8 user: drh tags: trunk) | |
| 16:39 | Merge all the latest changes from trunk. (check-in: 7ca58a07d3 user: drh tags: est_count_pragma) | |
| 14:47 | Fix then handling of the (oversized) integer literal -0x8000000000000000. (check-in: 3816bb415e user: drh tags: trunk) | |
| 05:08 | Change the OP_DecrJumpZero opcode back to its old behavior of always decrementing, except top the decrementing when it reaches the largest negative number. (check-in: 9d0d8c2e7c user: drh tags: trunk) | |
| 04:07 | More improvements to boundary cases in the date/time functions, flowing out of branch coverage testing. (check-in: 1218005ab7 user: drh tags: trunk) | |
| 01:05 | Prevent a warning about integer overflow when using a very large negative LIMIT. (check-in: 96106d5620 user: drh tags: trunk) | |
| 00:48 | Further changes to the date/time functions to suppress harmless signed integer overflow warnings that could have occurred when doing out-of-range date calculations which, according to the docs, give undefined results. (check-in: dc453b3403 user: drh tags: trunk) | |
|

| 20:39 | The documentation says that the built-in date-time functions give undefined results for dates before 0000-01-01 and after 9999-12-31. Change the actually implementation so that the answer given is really NULL. This also avoids unnecessary hand-wringing over an signed integer overflow that might otherwise occur when processing out-of-bound dates. (check-in: d410a83975 user: drh tags: trunk) | |

| 21:22 | Fix broken hyperlinks to the sqlite3_snapshot objection definition in the documentation. No changes to code. (check-in: 9021f6875f user: drh tags: trunk) | |
| 14:52 | Simplify some code in fts5_expr.c. Add some extra test cases for the same. (check-in: 7cc2d60dce user: dan tags: trunk) | |
|
2016-11-26
| ||
| 20:44 | Merge all recent trunk changes, and especially the new sqlite3_snapshot_recover() interface. (check-in: 41a3af5443 user: drh tags: apple-osx) | |
| 19:44 | Add the sqlite3_snapshot_recover() interface and related functionality. (check-in: b70c85ce6d user: drh tags: trunk) | |
|
2016-11-25
| ||
| 20:20 | Clarification of the behavior of sqlite3_stmt_readonly() on BEGIN IMMEDIATE statements. The is comment changes only - no changes to code. (check-in: a4205a83e4 user: drh tags: trunk) | |
| 19:32 | Remove the OP_RowKey opcode. Use OP_RowData in its place. (check-in: 6ac7b07a4a user: drh tags: trunk) | |
