| 18:32 | 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) | |
| 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: 94255634 user: drh tags: inner-loop-cost) | |

| 21:03 | Pull all the latest trunk enhancements into the sessions branch. (check-in: fce667f2 user: drh tags: sessions) | |
| 18:09 | Enable the use of coroutines as an alternative to manifesting views used in a FROM clause. (check-in: 9dca18f5 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: f83aa0de user: drh tags: subquery-as-coroutine) | |
| 14:44 | Fix a typo in the header comment for the OpenPseudo opcode. (check-in: 4f106123 user: drh tags: subquery-as-coroutine) | |
| 14:39 | Make it possible to disable the subquery-by-coroutine optimization using sqlite3_test_control(). Remove an always-false conditional. (check-in: 564631f3 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) | |
