| 18:05 | Performance optimization on the Column opcode. check-in: ecc98bef user: drh tags: trunk | |
| 14:19 | Performance optimization in sqlite3WalkExpr(). check-in: 2f8bd5fa user: drh tags: trunk | |
| 12:52 | Increase the version number to 3.11.0 due to the WAL overwrite enhancement. check-in: 8e807bfa user: drh tags: trunk | |
| 12:13 | If a single page is written to the wal file more than once, instead of appending the second and subsequent copy to the wal file, overwrite the first. Update: See the important bug fix at [f694e60a]! check-in: d493d4f1 user: dan tags: trunk | |
| 08:12 | Add a test case to waloverwrite.test to check that savepoint rollback does not cause a problem. Closed-Leaf check-in: 87dae56c user: dan tags: wal-overwrite-frames | |
| 03:48 | Slightly smaller and faster LIKE/GLOB comparison implementation. check-in: 5dddcc78 user: drh tags: trunk | |

| 23:55 | All WAL frame overwrites even if there are active savepoints. This is safe because a ROLLBACK TO will cause all reverted pages to be rewritten to the WAL file prior to COMMIT. check-in: 99b31a6b user: drh tags: wal-overwrite-frames | |
| 18:57 | If it is known that checksums will be recalculated on transaction commit, skip calculating checksums when appending frames to the wal file. When recalculating checksums, recalculate them starting with the first overwritten frame - not the first frame in the transaction. check-in: 16b34f25 user: dan tags: wal-overwrite-frames | |
| 16:39 | If a single page is written to the wal file more than once, have each subsequent copy overwrite the original frame. check-in: 5d113aef user: dan tags: wal-overwrite-frames | |

| 16:06 | Have the vdbe layer call sqlite3BtreeEnter() on all b-trees in use from within sqlite3VdbeExec() even in SQLITE_THREADSAFE=0 builds. This ensures that BtShared.db is set correctly. check-in: d0214602 user: dan tags: shared-cache-fix | |
| 02:06 | Add the "sqlite3 -sourceid" command in the TCL interface. Use that command and others to output additional information about the test configuration at the conclusion of a TCL test. check-in: 4f80440b user: drh tags: trunk | |
|

| 15:54 | Disable the --limit-mem option on fuzzcheck unless the SQLITE_ENABLE_MEMSYS5 or SQLITE_ENABLE_MEMSYS3 compile-time options are used. check-in: 55a11fd6 user: drh tags: trunk | |
| 11:01 | Version 3.10.0 check-in: fd0a50f0 user: drh tags: trunk, release, version-3.10.0 | |
|
2016-01-05
| ||
| 03:39 | Always use -DSQLITE_ENABLE_MEMSYS5 for fuzzcheck so that the --limit-mem option will work. check-in: a8556977 user: drh tags: trunk | |

| 13:06 | Fix the conflict2.test module which was broken by check-in [e30062e9f6c]. check-in: b779ca8a user: drh tags: trunk | |
| 12:07 | A new approach to very large sqlite3_mprintf() strings: Back out the [d655a665] check-in and instead make the size fields in StrAccum unsigned. Strings generated by sqlite3_mprintf() can now be as large as 2^31-1 bytes. check-in: 7adb789f user: drh tags: trunk | |
| 04:44 | Improved comment on the vtabH-3.1 test. check-in: 22abe080 user: drh tags: trunk | |

| 17:03 | Enhance the command-line shell so that it can handle MBCS characters on input and output. check-in: 3d81dfe3 user: drh tags: trunk | |
| 16:51 | Changes to the way that the default BINARY collating sequence is recorded result in a slightly smaller and slightly faster executable. More work could be done to make this cleaner. check-in: 2081d757 user: drh tags: trunk | |
| 15:18 | Simplification to the xfer-optimization logic. check-in: f35ba018 user: drh tags: trunk | |
| 14:06 | Remove unnecessary tests from the LIKE pattern matcher. Slightly faster and slightly smaller, and it should also now works with EBCDIC. check-in: 0a99a8c4 user: drh tags: trunk | |

| 10:54 | Enhance the 'utc' modifier on date/time functions so that if the LHS is already known to be in UTC, the modifier becomes a no-op. This is not an incompatibility because the behavior is documented as "undefined" in that scenario. check-in: b910a3d5 user: drh tags: trunk | |
|
2015-12-21
| ||

| 13:51 | Simplified alignment constraints in the memory reuse logic of sqlite3VdbeMakeReady(). check-in: e998513e user: drh tags: trunk | |
| 12:44 | Add the experimental snapshot interface. Because it is experimental, it is subject to change or removal at a later date. check-in: 9b124a5a user: drh tags: trunk | |
| 04:11 | Fix a memory allocation bug introduced last week by check-in [a9e819082ba]. The bug only appears on systems where the size of a structure is not always a multiple of 8 - which in practice means only on 32-bit windows systems. check-in: 96d3e99f user: drh tags: trunk | |
| 03:27 | Mention that the snapshot interfaces are only available if SQLite is compiled with SQLITE_ENABLE_SNAPSHOT. Closed-Leaf check-in: 843c15a5 user: drh tags: snapshot-get | |

| 22:48 | Snapshot documentation updates. Comment changes only - no changes to code. check-in: ef51a398 user: drh tags: snapshot-get | |
| 20:03 | Update the sqlite3_snapshot_get() API so that if the caller does not have an open read transaction on the named database, one is automatically opened. check-in: b9c90f10 user: dan tags: snapshot-get | |
| 19:44 | Add tests to snapshot.test. check-in: f3b74362 user: dan tags: snapshot-get | |

| 17:23 | Further simplifications to the VDBE code generation logic that flow out of the previous check-in. check-in: 6a5dfe85 user: drh tags: trunk | |
| 16:26 | Simplification of the DROP TRIGGER logic using sqlite3NestedParse() instead of hand-coded VDBE code. This is a manual cherry-pick of the key change from check-in [c80bbf14b365d]. check-in: 8021b4c8 user: drh tags: trunk | |
