| ||
| 18:58 | Minor tweaks to query planning weights so that when STAT4 is enabled and functioning, a full table scan is more likely to be selected if that seems like the fastest solution. Only do this when STAT4 info is available because an error has a large potential downside. (Leaf check-in: 263293f1 user: drh tags: branch-3.28) | |
|
2020-10-02
| ||
| 13:57 | Import further corner-case fixes for the in-scan-vs-index or OP_SeekScan optimization from trunk. (check-in: c144d640 user: drh tags: branch-3.28) | |
| 12:11 | For the OP_SeekScan optimization, the OP_IdxGT does not necessarily come right after the OP_SeekGE. So use the P2 operand of OP_SeekScan to point to the first instruction after OP_IdxGT. Problem found by dbsqlfuzz. (check-in: ec37744c user: drh tags: branch-3.28) | |
| 02:07 | Disable the OP_SeekScan opcode of the in-scan-vs-index optimization when in PRAGMA reverse_unordered_selects mode, as the OP_SeekScan only works with forwards scans. Thanks to OSSFuzz for pointing out the problem to us. (check-in: 9a1cdf7e user: drh tags: branch-3.28) | |
|
2020-09-30
| ||
| 18:22 | Improved query optimization for multi-column indexes where the second or later columns are constrained by an IN operator and the earlier index columns limit the search to a small number of rows. Use the new OP_SeekScan opcode which does scanning of the relevant range of the index but gives up and falls back to doing a seek if the number of rows scanned grows to large, in order to guard against pathological cases where the estimated number of rows to be scanned is far too small. (check-in: f07ac3fb user: drh tags: branch-3.28) | |
|
2020-09-01
| ||
| 02:02 | Improvements to the IN-early-out optimization so that it works more efficiently when there are two or more indexed IN clauses on a single table. (check-in: 49b7631e user: drh tags: branch-3.28) | |
|
2020-08-31
| ||
| 19:19 | An attempt to improve the performance of the IN-early-out optimization (see check-in [09fffbdf9f2f6ce3]) by avoiding unnecessary calls to the b-tree search algorithm in OP_IfNoHope when the index key is at hand and the same answer can be obtained by doing a quick key comparison. Update: Experiment did not work out. (Closed-Leaf check-in: 8301da31 user: drh tags: branch-3.28-in-early-out-fail) | |
|
2020-08-17
| ||
| 21:03 | When doing an UPDATE or DELETE using a multi-column index where only a few of the earlier columns of the index are useful for the index lookup, postpone doing the main table seek until after all WHERE clause constraints have been evaluated, in case those constraints can be covered by unused later terms of the index, thus avoiding unnecessary main table seeks.

| 14:56 | Do not allow shadow tables to be dropped in defensive mode. (check-in: ad1f760f user: drh tags: branch-3.28) | |
| 14:30 | Import the 3.31.0-beta FTS3/4 code directly into the 3.28 branch, thus providing 3.28 with all the latest 3.31 fixes. FTS3 has not been enhanced to use any core functionality that was not already available in 3.23, so no modifications were made to FTS3 sources for this import. (check-in: be4269c6 user: drh tags: branch-3.28) | |

| 18:35 | In the Table object, change the nVCol field to nNVCol - the number of non-virtual columns, as that is the quantity that we need most. (check-in: 4ad66af0 user: drh tags: generated-columns) | |
| 18:07 | Bug fix with INSERT using an explicit column list on a table with a non-final STORED column. (check-in: 61b4459a user: drh tags: generated-columns) | |

| 13:15 | Fix the table_info and table_xinfo pragmas so that they work with virtual columns. Table_info omits virtual columns. Table_xinfo gives them a "hidden" flag of 2, and 3 for STORED columns. (check-in: 069351b8 user: drh tags: generated-columns) | |

| 14:56 | If an AFTER DELETE trigger fires when a conflict row is deleted by REPLACE conflict resolution, make sure the conflict really has been resolved and that the trigger did not recreate the row before continuing. Ticket [a8a4847a2d96f5de] (check-in: eea1e7aa user: drh tags: trunk) | |
