| 18:00 | Fix test cases so that they work with the new EXPLAIN QUERY PLAN output format. Only some of the cases have been fixed. This is an incremental check-in. file: [88287550] check-in: [5f0e803e] user: drh branch: rework-EQP, size: 105392 | |

| 20:24 | Performance enhancement for single-table queries with many OR-connected WHERE clause terms and multiple indexes with the same left-most columns. file: [55a32217] check-in: [1461d543] user: drh branch: trunk, size: 105416 | |

| 02:00 | Fix a couple of typos in comments. No changes to code. file: [63599653] check-in: [a758465e] user: mistachkin branch: trunk, size: 104378 | |
| 01:35 | Query planner heuristic update: When doing a full table scan on a table that has an equality constraint on an unindexed column, do not allow the estimated number of output rows to be greater than half the total number of rows in the table. file: [1c351691] check-in: [73954f93] user: drh branch: trunk, size: 104381 | |

| 16:01 | Fix a problem causing an inaccurate stat4-based estimate for the number of rows visited by a range scan. file: [8880784c] check-in: [052d89b5] user: dan branch: stat4-experimental, size: 88287 | |

| 16:50 | Oops! This check-in was on trunk. But it contains a debugging printf(). Original comment: When the estimated cost to do a sort overwhelms the estimated cost to do individual table lookups, make sure that the table lookup costs are still taken into consideration when selecting the lookup algorithm. file: [35a40a50] check-in: [ec5d84ba] user: drh branch: query-planner-fix, size: 87024 | |
