Take into account the cost of inner loops when selecting which table of a join to use for the next outer loop. (check-in: 3f87f459 user: drh tags: trunk)
18:22
Disable the table selection rule that tried to prevent full table scans from migrating to the outer loop unless they were optimal. The new scaling of outer-loop costs by cost of inner loops obviates the need for that step. And, in fact, that step causes problems with the new inner-loop cost accounting. (Closed-Leaf check-in: 51bfd63b user: drh tags: inner-loop-cost)

Try to take into account the cost of inner loops when selecting which table of a join to use for the outer loop. (check-in: 94255634 user: drh tags: inner-loop-cost)

15:31
Make sure that the optimizer never tries to create an automatic index on a coroutine subquery. (Closed-Leaf check-in: f83aa0de user: drh tags: subquery-as-coroutine)

00:29
Add an optimization that attempts to run a subquery as a coroutine rather than manifesting it into a temporary table. (check-in: 7af3acbb user: drh tags: subquery-as-coroutine)
2012-10-29
14:27

19:22
Fix a 32-bit integer overflow problem that could cause an error in a CREATE INDEX statement that writes more than 16GB of data. (check-in: e24ba5be user: dan tags: trunk)
18:40
Make sure the automatic index optimization is checked even if the covering index scan optimization was previously selected. (check-in: ac1d5d8a user: drh tags: trunk)
13:46

00:55
Make sure all virtual table cursors have been closed on a prepared statement prior to unlinking the perpared statement from its database connection. The test case for this is in TH3, in the main39.test module. (check-in: 6d42d806 user: drh tags: trunk)
00:11
Make sure all virtual table cursors have been closed on a prepared statement prior to unlinking the perpared statement from its database connection. (Closed-Leaf check-in: f7c5abe8 user: drh tags: deferred-close-order)
2012-10-25
23:47
Further work on getting ssdsim to run. This is an incremental checkin to save my place while jumping off to work on other things. (Leaf check-in: ae2f1627 user: drh tags: ssdsim)
19:25
Fix a bug in fts3 causing it to return SQLITE_NOMEM when NEAR, OR and some auxiliary functions were used together. Also a segfault in vtab.c that could follow an OOM condition. (check-in: 33f4f981 user: dan tags: trunk)
15:43
Fix typo in usage text for the command-line shell. Also, in the same usage text, make the file name argument to -init uppercase for consistency. (check-in: a6d906cf user: mistachkin tags: trunk)

Improvements to the command-line argument parsing in the command-line shell. Command-line options can now occur either before or after the database name and first command and are still accepted and processed. Command-line options are processed even if no database name is given (and :memory: is assumed). (check-in: 317c80cb user: drh tags: trunk)
03:07
Implementation of the INSTR() SQL function, as found in SQL Server, MySQL, and Oracle. (Closed-Leaf check-in: 49ccae96 user: drh tags: instr)
