| 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]. check-in: 299b9570 user: dan tags: query-planner-fix | |

| 18:47 | Add "segment promotion" to fts5. This prevents the FTS index from growing indefinitely as data is added and deleted. check-in: ba359d78 user: dan tags: fts5 | |
| 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. check-in: ec5d84ba user: drh tags: query-planner-fix | |

| 00:29 | A simpler fix for ticket [3a88d85f36704eebe1] - one that uses less code. The error message is not quite as good, but as this error has apparently not previously occurred in over 8 years of heavy use, that is not seen as a serious problem. check-in: 0ad1ed8e user: drh tags: trunk | |

| 21:31 | Ensure that aggregate functions are not used when evaluating a default value for a table column. Candidate fix for ticket [3a88d85f36704eebe134f7]. check-in: 29ba8128 user: drh tags: trunk | |
| 19:35 | Use doclist indexes for AND queries as well as phrases. check-in: 5d38e6ed user: dan tags: fts5 | |
| 19:16 | Add the ability to evaluate IN operators as a sequence of comparisons as an alternative to the long-standing algorithm of building a lookup table. Use the new implementation in circumstances where it is likely to be faster, such as when the RHS of the IN changes between successive evaluations. check-in: 95286821 user: drh tags: trunk | |

| 18:00 | Remove an unnecessary OP_Null in the IN-operator logic. Attempt to clarify comments explaining the IN-operator code, though it is not clear that the comments are correct even yet - more work to be done. check-in: c11e55fa user: drh tags: trunk | |
| 15:51 | Clean up the IN operator code generation logic to make it easier to reason about. In the process, improve code generation to omit some unused OP_Null operations. check-in: 7c6fbcfe user: drh tags: trunk | |
| 15:34 | The idea of coding IN operator with a short list on the RHS as an OR expression turns out to be helpful. If the list is of length 1 or 2, the OR expression is very slightly faster, but the ephemeral table approach is clearly better for all list lengths greater than 2. Better to keep the code simple. Closed-Leaf check-in: e13175d3 user: drh tags: IN-operator-improvements | |

| 11:16 | Add "doclist index" records to the database. These are to make navigating within very large doclists faster. They are not yet used by queries. check-in: 89377421 user: dan tags: fts5 | |

| 15:44 | Deactivate the DISTINCT in a SELECT on the right-hand side of an IN operator, since it should not make any difference in the output but dues consume extra memory and CPU time. check-in: f4cb5365 user: drh tags: trunk | |

| 19:41 | Add hidden column "rank". Currently this always returns the same value as the bm25() function. check-in: 4cc048c3 user: dan tags: fts5 | |

Shutdown is not done if there are pending database connections and eForce is false, but an error log entry is made instead. check-in: c7303d01 user: drh tags: trunk | |
