|
2022-10-19
| ||
| 11:22 | If a query uses an index where one or more of the columns of the index is an expression and if the corresponding expression is used elsewhere in the query, then strive to read the value of the expression out of the index, rather than recomputing it.

| 19:29 | Attempt to omit ORDER BY clauses from FROM-clause subqueries if those ORDER BY clauses do not affect the output. See forum thread 2d76f2bcf65d256a for discussion. This can help the query flattener in some cases, resulting in faster query plans. The current implemention does not always work. (check-in: ef97c3e7c3 user: drh tags: omit-subquery-order-by) | |

| 13:52 | Enhance the sqlite3_create_function() interfaces to assume a value of SQLITE_UTF8 is presented with a nonsense value for the preferred encoding. This is undocumented behavior added for robustness. (check-in: c1bb5cff52 user: drh tags: trunk) | |
| 11:52 | Add the usual "#ifdef __cplusplus" magic to header file ext/misc/carray.h. Also update carray.h/carray.c to use SQLITE_API in the usual way. (check-in: 0f97c2a459 user: dan tags: trunk) | |

| 16:48 | Follow-up to [68db1ff9c44fa9c3]: The number of registers needed by PRAGMA foreign_key_check was increased too late for an assert() deep down inside of sqlite3ExprCode(). So move the size increase a little earlier. Forum post 79c9e4797d. (check-in: 7072404ad0 user: drh tags: trunk) | |
| 15:52 | Fix a recently introduced segfault that might occur if a sub-select were used as a term on the RHS of an IN(...) operator for which the LHS is a row-value. (check-in: f586c06a5d user: dan tags: trunk) | |
| 13:53 | Improve the error message in cases where there is a row-value on the LHS of an IN() operator, the RHS is a list (not a sub-select) and at least one element of the list is not a row-value with the correct number of elements. (check-in: 6b22f4e71d user: dan tags: trunk) | |
| 11:51 | Instead of disallowing writes to fts5 tables if there are fts5vocab cursors open on them (commit [c49a6ed7]), abort any fts5vocab queries if the on-disk structure of the fts5 table changes. (check-in: 9dbdc9001e user: dan tags: trunk) | |

| 18:37 | Add the ATOMIC_INTRINSICS compile-time output output. Move sqlite3Int.h in front of ctime.c so that default values that are not overridden are shown in PRAGMA compile-time option output. (check-in: e306952690 user: drh tags: trunk) | |
| 17:15 | Revert [5204c2c4a7b73a64], restoring the old pre-processor logic for determining the availability of the __atomic_store_n()/__atomic_load_n() primitives. (check-in: e690abb9e4 user: dan tags: trunk) | |
| 11:27 | Allow sub-queries in the FROM clause of an UPDATE...FROM statement to access the object being updated without using an alias, as is required in the parent query. (check-in: 740cb43025 user: dan tags: trunk) | |
| 02:40 | Improved rebustness in sqlite3ExprListDup() when it contains a vector assignment from an UPDATE where the initial term is omitted. This can happen during a UNION ALL query flattening while processing a virtual table update in which the first term of the vector is repeated. Forum post 16ca0e9f32. (check-in: 2547cfe38f user: drh tags: trunk) | |
| 01:11 | Ensure that TK_SELECT_COLUMN Expr nodes always have their iTable field set to to the number of columns in the vector. This is not strictly necessary. It just simplifies the state description and make the code easier to reason about. (check-in: 026f08d4cf user: drh tags: trunk) | |

| 12:25 | Put ALWAYS() on a branch that is always true due to [d4097364c511709b]. Fix a testcase precondition associated with the same check-in. (check-in: 55e2fbebb0 user: drh tags: trunk) | |
| 12:08 | Fix a harmless assertion fault discovered by OSSFuzz. The assertion fault is harmless because the assert() checks a condition that that is harmless if false and the assert() is disabled in production builds. (check-in: 79443aabe1 user: drh tags: trunk) | |

|
2021-06-25
| ||
| 14:48 | The OP_ReopenIdx opcode should clear the cursor if the cursor is being reused. This prevents leaving the cursor in an initialized state which could cause problems for a subsequent OP_SeekScan opcode. Fix for ticket [6dcbfd11cf666e21] and the OP_SeekScan optimization of check-in [4a43430fd23f8835]. (check-in: d4bf5243f2 user: drh tags: trunk) | |

| 23:30 | This is another alternative fix to the covering index on WHERE_MULTI_OR in a LEFT JOIN problem that is fixed on trunk nearby. In this alternative, covering indexes are simply disabled for WHERE_MULTI_OR on a LEFT JOIN. This might have run-time impact on some obscure queries. This patch is saved for historical reference only. (Closed-Leaf check-in: 668564100e user: drh tags: multi-or-covidx-fix3) | |
| 23:27 | This is an alternative fix to the covering index on WHERE_MULTI_OR in a LEFT JOIN problem that is fixed nearby. This one works by having the OP_NullRow opcode create the index if it does not already exist. That is slightly more complex. This patch is saved for historical reference only. (Closed-Leaf check-in: 956bafb69f user: drh tags: multi-or-covidx-fix2) | |
| 23:24 | When an index is used by all branches of the WHERE_MULTI_OR optimization and becomes a covering index, make sure the index has been created prior to NULLing it in the OP_NullRow opcode of a LEFT JOIN. See forum post 0575376e07. The covering-index for WHERE_MULTI_OR optimization was added by [62678be3df35cdcb]. Test cases are in the orindex01.test module of TH3.
