| 14:24 | The simplification to sqlite3SelectExpand() in last night's [3a4ffb21] check-in was not completely correct. This adjustment is needed for correct OOM handling in some configurations. (check-in: c5ad5e1675 user: drh tags: trunk) | |

| 13:20 | Avoid using lookaside memory for persistent virtual table structures. (check-in: d815f255df user: drh tags: trunk) | |
| 02:52 | The query planner now always prefers to implement a FROM-clause subquery using a co-routine rather than flattening the subquery into the outer query. (check-in: c9104b59c7 user: drh tags: trunk) | |
| 02:32 | Improvements to a comment in lempar.c. No code changes. (check-in: 8000d23017 user: drh tags: trunk) | |

| 01:25 | Fix unreachable conditionals and revise a testcase that was made obsolete by the changes on this branch. (check-in: 71f0adf7ca user: drh tags: prefer-coroutine-sort-subquery) | |

| 16:08 | Merge the query flattener comment improvements from trunk. (check-in: f62cd4d940 user: drh tags: prefer-coroutine-sort-subquery) | |
| 16:07 | Clean up the comments on the query flattener to more clearly and accurately express the conditions under which the flattener is able to run. (check-in: 0840f9f824 user: drh tags: trunk) | |
| 14:31 | Merge changes from trunk. (check-in: 06f432fb7c user: drh tags: prefer-coroutine-sort-subquery) | |

| 20:06 | Do not flatten subqueries that contain an ORDER BY or GROUP BY clause and can be implemented using a co-routine. (check-in: 042d655dd9 user: drh tags: prefer-coroutine-sort-subquery) | |
| 17:29 | Remove the (undocumented) query-planner control that prevents a "SELECT ALL" subquery in FROM clause from being implemented as a co-routine. This control was added by [a29e117d7ec], where it was called a "stop-gap". (check-in: ff2f5a31a2 user: drh tags: trunk) | |
| 16:56 | Fix over-length source code lines in select.c. No logic changes. (check-in: fd3267ef92 user: drh tags: trunk) | |
