| 11:21 | Fix multiple problems with RETURNING on a DML statement against a view. (1) Do not allow a RETURNING clause to trick the code generator into thinking that the view being updated has an INSTEAD OF trigger. (2) Generate all result columns for a view in a DML statement. (3) The automatic covering index for a view should cover all result columns of the view. (check-in: b49816fcce user: drh tags: branch-3.41) | |
|
2023-03-27
| ||
| 13:27 | Do not allow constant factoring during PRAGMA integrity_check, since the constants might be stored in registers that are later reused for other purposes. (check-in: a4b5f499d9 user: drh tags: branch-3.41) | |

|
2023-03-25
| ||
| 23:56 | When the left table of a RIGHT JOIN is used inside an aggregate function and the left table employs an index on expressions, then make sure the expressions evaluate to NULL for the cases where the left table should be NULL. (check-in: c51df77ebe user: drh tags: branch-3.41) | |
| 22:42 | When reading sqlite_stat4 data during query planning, be sure to expand zeroblobs prior to running comparisons. (check-in: 60f4d19d91 user: drh tags: branch-3.41) | |
| 19:46 | In the byte-code generator, when the result of an expression needs to be in a particular register, always use the sqlite3ExprCode() routine because it has the smarts to know whether to use OP_Copy or OP_SCopy. Do not try to OP_SCopy inline because an OP_Copy might be required. (check-in: 2d439ccca4 user: drh tags: branch-3.41) | |
| 18:33 | The fix at [13c8c60bb6b4447b] was incomplete in that it failed to clear the reusable register cache that might contain registers in the STAT4 buffer region. This additional change corrects the problem. (check-in: 671bf6f532 user: drh tags: branch-3.41) | |
| 02:02 | Fix a problem in cursor-hints for WITHOUT ROWID tables. (check-in: fc8ec188d9 user: drh tags: branch-3.41) | |

| 17:01 | Fix byte-code register allocation in ANALYZE for STAT4 when there multiple indexes with differing numbers of columns. (check-in: 13c8c60bb6 user: drh tags: branch-3.41) | |
|
2023-03-23
| ||
| 10:58 | The attempt to bring STAT4 up to 100% MC/DC at [55a26c67ed4a3a93] and at [168fa2fb22b8c1ad] are incorrect. Back them out and replace them with a simple NEVER() macro. Error reported by forum post dc4854437b. (check-in: 76e683c5f2 user: drh tags: branch-3.41) | |

| ||
| 16:04 | In the Bloom filter optimization, hash all strings and blobs into the same value, because we do not know if two different strings might compare equal even if they have different byte sequences, due to collating functions. Formerly, the hash of a string or blob was just its length. This could all be improved. (check-in: cc8a0ee40c user: drh tags: branch-3.41) | |

| 15:36 | Fix to check-in [b9190d3da70c4171] - the agg-with-indexed-expr optimization requested by ticket [99378177930f87bd] - that can cause an incorrect answer if an aggregate subquery has a GROUP BY clause, and that GROUP BY contains a term that is not in the result set, and the outer query makes use of expression indexes. Problem reported by forum post a68313d054. (check-in: e069738769 user: drh tags: trunk) | |

| 17:11 | Cherrypick the "(X IS [NOT] NULL)" fix from trunk onto branch-3.41. (check-in: 0fc7f7c2a9 user: drh tags: branch-3.41) | |
| 16:25 | When it is known when preparing a statement that X cannot be NULL or is always NULL, transform the expression (X IS NULL) to integer value 1 or 0 instead of 'true' or 'false'. This is because under some circumstances, "Y IS TRUE" or "Y IS FALSE" may not be equivalent to "Y IS 1" of "Y IS 0".

For the time being, do not add sqlite3_wasm_extra_init.c to fiddle.wasm because it can cause duplicate definitions of extensions which are already built into the shell (a better resolution for this conflict is pending).

| 14:28 | In the Bloom filter optimization, hash all strings and blobs into the same value, because we do not know if two different strings might compare equal even if they have different byte sequences, due to collating functions.
