2023-11-29
16:26
Fix a duplicate assert() caused by the second cherrypick in the previous check-in. (Leaf check-in: f10d4fc4 user: drh tags: branch-3.28)
16:07
Remove Window objects from the corresponding Select.pWin list when they are deleted, as they are, for example, when the ORDER BY clause is optimized out. (check-in: f9c6e6a7 user: drh tags: branch-3.28)
2023-10-19
21:05
Ensure that when an ephemeral cursor is reopened with a second invocation of to OP_OpenEphemeral, the sequence counter is reset and the cache marked as stale. Fix for [9cdc5c46]. (check-in: d4bfa8d2 user: drh tags: branch-3.28)
2023-09-15
20:04
Drop support for the view-scan optimization as it was causing multiple performance regressions. In its place, reduce the estimated row count for DISTINCT subsqueries by a factor of 8. (check-in: 796a65fa user: drh tags: branch-3.28)
2023-02-26
11:52
In the omit-unused-subquery-columns optimization, be sure to remove the EP_Skip and EP_Unlikely flags from the result set expressions that get nulled-out. dbsqlfuzz bf1d3ed6e0e0dd8766027797d43db40c776d2b15. Also fix an incorrect ".selecttrace" code block. (check-in: 83a7f13e user: drh tags: branch-3.28)
2023-02-16
21:01
Fix an #ifdef that uses a different macro name from the main branch. (check-in: ad6ac5d3 user: drh tags: branch-3.28)
19:04

14:29
Do not compute result columns of subqueries that are never used. Make those columns NULL instead. This optimization potentially resolves the enhancement request described by [ticket baa5bb76c35a124c]. (check-in: 0163b697 user: drh tags: branch-3.28)
2022-10-24
13:50
Improve the ability of the query planner to recognize covering indexes even on tables with more than 63 columns and where the index is over columns beyond the 63rd column. (check-in: 3d1992de user: drh tags: branch-3.28)
2022-10-19
11:22
If a query uses an index where one or more of the columns of the index is an expression and if the corresponding expression is used elsewhere in the query, then strive to read the value of the expression out of the index, rather than recomputing it. This is the "Indexed Expression Optimizations". (check-in: 3da10328 user: drh tags: branch-3.28)
2022-09-01
10:41
In the query planner, add a heuristic that will reduce the cost of a full table scan for a materialized view or subquery if the full scan is the outer-most loop. This is shown to speed up some queries. (check-in: e3754cc1 user: drh tags: branch-3.28)
2022-08-10
17:03

2021-11-08
16:38
Add assert()s that verify that cursor numbers on subqueries are always greater than outer cursor numbers. Except, this is not always true in the presence of query flattening. We might need to relax that constraint. This branch will probably become a dead-end. For now it is saved for reference. (Closed-Leaf check-in: 6f436966 user: drh tags: well-ordered-cursors)
15:46
Fix an assert() in memdbTruncate() that could fail when processing a corrupt database. (check-in: b1e29298 user: dan tags: trunk)
2021-11-07
23:33

12:34
Use the FTS_CORRUPT_VTAB macro rather than a direct call to sqlite3Fts3Corrupt() in [2fad2a89527757b3] so that the build works in all cases. (check-in: 029c59cd user: drh tags: trunk)

Fixes to the version of "varsep" group_concat so that (1) it builds under separate compilation and (2) omits tabs in source code and (3) runs faster than trunk.
