2016-11-26
19:44
Add the sqlite3_snapshot_recover() interface and related functionality. (check-in: b70c85ce6d user: drh tags: trunk)
2016-11-25

Remove the OP_RowKey opcode. Use OP_RowData in its place. (check-in: 6ac7b07a4a user: drh tags: trunk)
19:18
Refactor the sqlite3BtreeKey() and sqlite3BtreeData() internal interfaces into sqlite3BtreePayload() and sqlite3BtreePayloadChecked(), respectively.

2016-11-18
20:49
Add experimental sqlite3_snapshot_recover() API. (check-in: 174a6076a8 user: dan tags: serializable-snapshot)
18:43
Require that the database handle be in autocommit mode for sqlite3_snapshot_get() to succeed. This is because it may open a read transaction on the database file. (check-in: 83b658dad0 user: dan tags: serializable-snapshot)
18:22
Add tests for snapshot interfaces. (check-in: 1f7ee7af7b user: dan tags: serializable-snapshot)

13:13
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: 005d5b8706 user: drh tags: trunk)

17:25
Fix the ossfuzz.c test module so that it does not segfault after a "PRAGMA empty_result_callbacks=1;". Add the ossshell.c program for simple command-line testing of ossfuzz.c. (check-in: 6f2d43eca6 user: drh tags: trunk)
15:28

19:01
Enhance the OP_IdxInsert opcode so that it can used unpacked key values if they are available. Update the code generator to take advantage of this new capability. The speedtest1.c test is about 2.6% faster as a result. Later: This also introduced bug [30027b613b]. Bummer. (check-in: 925840cfdb user: drh tags: trunk)
18:45
Merge trunk with this branch. (Closed-Leaf check-in: dd62d2de6e user: dan tags: sorter-opt)
