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
2016-11-25
20:20

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

21:01
Disable the query flattener optimization for SELECT statements that are on the RHS of vector IN operators. This is a hack that fixes the bug described in ticket [da7841375186386c]. A better solution that does not disable the query flattener is needed, but this will server for the time being. check-in: 27438fb4 user: drh tags: branch-3.15
