| 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: 9d0d8c2e user: drh tags: trunk | |
| 04:07 | More improvements to boundary cases in the date/time functions, flowing out of branch coverage testing. check-in: 1218005a user: drh tags: trunk | |
| 01:05 | Prevent a warning about integer overflow when using a very large negative LIMIT. check-in: 96106d56 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: dc453b34 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: d410a839 user: drh tags: trunk | |

| ||
| 21:22 | Fix broken hyperlinks to the sqlite3_snapshot objection definition in the documentation. No changes to code. check-in: 9021f687 user: drh tags: trunk | |
| 14:52 | Simplify some code in fts5_expr.c. Add some extra test cases for the same. check-in: 7cc2d60d user: dan tags: trunk | |
|
2016-11-26
| ||
| 20:44 | Merge all recent trunk changes, and especially the new sqlite3_snapshot_recover() interface. check-in: 41a3af54 user: drh tags: apple-osx | |
| 19:44 | Add the sqlite3_snapshot_recover() interface and related functionality. check-in: b70c85ce user: drh tags: trunk | |
|

| 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: a4205a83 user: drh tags: trunk | |
| 19:32 | Remove the OP_RowKey opcode. Use OP_RowData in its place. check-in: 6ac7b07a user: drh tags: trunk | |
| 19:18 | Refactor the sqlite3BtreeKey() and sqlite3BtreeData() internal interfaces into sqlite3BtreePayload() and sqlite3BtreePayloadChecked(), respectively. This is a continuation of the optimization started by check-in [2d831074cf]. The result is a slightly smaller and faster binary. check-in: 49ebc219 user: drh tags: trunk | |
| 17:03 | Small performance increase and size reduction in the OP_Column opcode. check-in: a9498407 user: drh tags: trunk | |
| 15:47 | Performance enhancement to sqlite3_snprintf(). check-in: c53dca7f user: drh tags: trunk | |
| 15:11 | Performance improvement in sqlite3StrAccumFinish() for the common case where no memory allocation is required. check-in: b6acf5d4 user: drh tags: trunk | |
| 14:30 | Add a comment to help clarify the EP_FromJoin hack in exprCodeBetween(). check-in: 6df7c574 user: drh tags: trunk | |
