18:26
Update requirements marks. No changes to code. (check-in: 7556bd9a user: drh tags: trunk)
17:49
Improvements to the way the query planner handles sorting costs, so that very large sorting costs do not overwhelm the loop costs. (check-in: bdaa6947 user: drh tags: trunk)
17:25
Fix a buffer overrun in the previous commit. (Closed-Leaf check-in: 43c59c85 user: dan tags: query-planner-fix)
16:52
Because SQLite internally calculates query plan costs using a logarithmic scale, very large estimated sorting costs can cause all other estimated costs to be rounded down to zero. In these cases break ties between plans with the same total cost by comparing the costs with sorting excluded. This is an alternative fix for the problem addressed by [2af630c572].

15:38
The SQLITE_IOERR_BLOCKED extended error code is not longer used, so remove assert() statements and documentation for that error code. Also make other documentation improvements. (check-in: 36b7c5ce user: drh tags: trunk)
