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: 51bfd63b7f user: drh tags: inner-loop-cost)
17:59
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: 942556342a user: drh tags: inner-loop-cost)

Enable the use of coroutines as an alternative to manifesting views used in a FROM clause. (check-in: 9dca18f5fe user: drh tags: trunk)
15:31
Make sure that the optimizer never tries to create an automatic index on a coroutine subquery. (Closed-Leaf check-in: f83aa0de84 user: drh tags: subquery-as-coroutine)

Add an optimization that attempts to run a subquery as a coroutine rather than manifesting it into a temporary table. (check-in: 7af3acbbd4 user: drh tags: subquery-as-coroutine)

14:27

2012-10-25
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: 33f4f9817e 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: a6d906cfeb user: mistachkin tags: trunk)
15:23
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: 317c80cba3 user: drh tags: trunk)

Correct comments and enhance readability of the mkvsix tool. (check-in: 2c3af657fe user: mistachkin tags: trunk)

Ensure that when the source of a backup is a database that is zero bytes in size, the final destination database consists of at least one page. Truncating it to zero bytes is equivalent to zeroing the schema cookie and change counter, which can cause problems for existing clients. (check-in: ca86138bda user: drh tags: trunk)
20:55
Mark an always-true conditional as such. (Closed-Leaf check-in: ae025cae22 user: drh tags: zero-byte-backup-fix)

19:58
Ensure that when the source of a backup is a database that is zero bytes in size, the final destination database consists of at least one page. Truncating it to zero bytes is equivalent to zeroing the schema cookie and change counter, which can cause problems for existing clients. (check-in: af5c9ee4a4 user: dan tags: zero-byte-backup-fix)
