16:14 | Unintentional edits mistakenly checked in. Was: Remove an obsolete and incorrect comment from the whereLoopOutputAdjust() routine in the query planner. No changes to working code. (Closed-Leaf check-in: e1f893c606 user: drh tags: mistake) | |
12:22 | Remove a redundant test case (probably a copy/paste error). Add an assert() to where.c to ensure that automatic indexes do not have there output row counts adjusted downward by supplementary constraints. (check-in: eea4793349 user: drh tags: trunk) | |
