Add a new requirement mark for CAST expressions. (check-in: bee2859b user: drh tags: trunk)
19:15
Update requirement marks to reflect changes in wording in the documentation. No changes to code. (check-in: f5ac98ef user: drh tags: trunk)
01:26
Remove unnecessary OP_Close opcodes for a size reduction and performance increase. (check-in: 32be7aae user: drh tags: trunk)
2016-11-21
21:33
Remove unnecessary OP_Close opcodes at the end of INSERT operations, resulting in smaller and faster code. (check-in: abeddb6d user: drh tags: trunk)
18:15
Enhance speedtest1.c so that is works on older versions of SQLite, before the introduction of the group_concat() aggregate function. (check-in: 9979ba80 user: drh tags: trunk)
2016-11-20
17:59
Fix harmless compiler warnings. (check-in: b3b7b42d user: drh tags: trunk)
12:00
Prevent a possible use-after-free bug in the query optimizer. (check-in: 0a98c8d7 user: drh tags: trunk)
2016-11-19
18:31
Remove the requirement to open the wal file before sqlite3_snapshot_recover() is called. Also add some comments to new functions. (check-in: 28393c41 user: dan tags: serializable-snapshot)
17:30
Test some extra error conditions in sqlite3_recover_snapshot(). (check-in: db314213 user: dan tags: serializable-snapshot)
17:20
Add another fault-injection test for sqlite3_snapshot_recover(). (check-in: 7e040406 user: dan tags: serializable-snapshot)
16:35
Fix a problem causing sqlite3_snapshot_recover() to return SQLITE_IOERR_SHORT_READ. (check-in: 525f75fa user: dan tags: serializable-snapshot)
14:53
Fix a bug in sqlite3_snapshot_recover() that could cause subsequent read transactions to use out-of-data cache entries. (check-in: 9abeb798 user: dan tags: serializable-snapshot)
2016-11-18
20:49
Add experimental sqlite3_snapshot_recover() API. (check-in: 174a6076 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: 83b658da user: dan tags: serializable-snapshot)
18:22
Add tests for snapshot interfaces. (check-in: 1f7ee7af user: dan tags: serializable-snapshot)
14:38
Enhance existing snapshot tests to serialize/deserialize snapshots. No new tests. (check-in: 16b9bf92 user: dan tags: serializable-snapshot)
2016-11-17
21:52
Experimental changes for faster in-memory DB operation for large databases. (Closed-Leaf check-in: 4fe94b0f user: drh tags: memdb-opt)

13:54
Change the --enable-debug option on configure so that it enables the ".selecttrace" and ".wheretrace" commands in the command-line shell. (check-in: 2331192b user: drh tags: trunk)
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: 005d5b87 user: drh tags: trunk)
2016-11-15
21:17
Add a needed #include to speedtest1.c. (check-in: 77aeb705 user: drh tags: trunk)
17:37
Experimental changes toward making snapshots serializable. (check-in: b6a81fa1 user: drh tags: serializable-snapshot)
04:00

02:46

2016-11-14
20:47

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: 6f2d43ec user: drh tags: trunk)
15:28
Avoid unnecessary calls to sqlite3ExprCacheAffinityChange() when generating OP_MakeRecord opcodes that do not change any register affinities. (check-in: e211c579 user: drh tags: trunk)
08:19
