|
2019-11-07

|
2019-11-03
| ||
| 00:07 | The optimization of check-in [9b2879629c34fc0a] is incorrectly reasoned. The WHERE clause of the partial index might not be true if the table of the partial index is the right table of a left join. So disable the optimization in that case. Ticket [623eff57e76d45f6] (check-in: 3be19e11 user: drh tags: trunk) | |
|
2019-11-02

| 13:32 | In sqlite3GenerateIndexKey(), do not attempt to reuse column values from the previous index if the current index is a partial index as the partial index test may have changed those values. Ticket [a9efb42811fa41ee] (check-in: 17e9f658 user: drh tags: trunk) | |

| 16:08 | Add another missing column number translation to the foreign key logic. (check-in: 32df5edc user: drh tags: trunk) | |
| 15:19 | Omit the optimization that reduces the column-count on rowid-table cursors when the table has generated columns, because we do not know what columns the generator expressions might try to access. (check-in: e6c96ed9 user: drh tags: trunk) | |

| 13:16 | Ignore differences in Expr.op2 in sqlite3ExprCompare() in cases where it does not matter. Ticket [1d2a8efc6c3a595a]. (check-in: 32982067 user: drh tags: trunk) | |
| 12:30 | Enhance the TreeView logic to show information about Expr.op2 for FUNCTION and COLUMN nodes. (check-in: aceeaf9e user: drh tags: trunk) | |
|
2019-10-30

| 18:50 | Always disallow the use of non-deterministic functions in CHECK constraints, even date/time functions that use the 'now' or similar keywords. Provide improved error messages when this requirement is not met. Ticket [830277d9db6c3ba1] (check-in: 2978b65e user: drh tags: trunk) | |
| 16:29 | Simplify the bytecode generation for SQL function calls such that the OP_Function or OP_PureFunc opcodes are coded directly, rather than using the intermediate OP_Function0 or OP_PureFunc0 - opcodes that are now removed. (check-in: 84e02d77 user: drh tags: trunk) | |

| 03:39 | Tighten the generated column requirement such that every table must have at least one non-generated column. Ticket [166347c6fc994155]. (check-in: 4fba090e user: drh tags: trunk) | |

|
2019-10-26
| ||
| 23:51 | Remove code from the constraint checker that generates virtual column values with the incorrect time. Turns out the the regular code for all other columns works correctly and so the incorrect special-case code is not actually needed. Fix for ticket [3ea175512444b0d1]. (check-in: 5b4c0f2d user: drh tags: trunk) | |
| 18:56 | Remove redundant code resulting from a merge error on the previous check-in. (check-in: 713fe86b user: drh tags: trunk) | |
| 18:47 | Add support for generated columns. (check-in: b855acf1 user: drh tags: trunk) | |

| 12:27 | Overnight, OSSFuzz helpfully pointed out a potential use-after-free bug in yesterdays changes, involving continued use of a pointer after the memory pointed to had been realloc()-ed. Thanks Google. (check-in: c422afb5 user: drh tags: trunk) | |
