|
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. This is the "Indexed Expression Optimizations". (check-in: 3da1032878 user: drh tags: branch-3.28) | |
|
2022-09-01
| ||
| 10:41 | In the query planner, add a heuristic that will reduce the cost of a full table scan for a materialized view or subquery if the full scan is the outer-most loop. This is shown to speed up some queries. (check-in: e3754cc188 user: drh tags: branch-3.28) | |

|
2021-07-13
| ||
| 15:30 | Remove two incorrect assert() statements from the logic used to derive column names and types from subqueries. This allows the SQL associated with CVE-2020-13871 (ticket [c8d3b9f0a750a529]) to be tested. (Closed-Leaf check-in: d2e6722037 user: dan tags: branch-3.28a) | |

| 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) | |
| 00:07 | Fix an incorrect comment on testcase misc1-27.0. No changes to code. (check-in: 49829ae322 user: drh tags: trunk) | |

Forum post a6b0c05277. (check-in: 68db1ff9c4 user: drh tags: trunk) | |
|
2021-07-02
| ||
| 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) | |
|
2021-07-01
| ||
| 18:19 | Allow unqualified "rowid" references to be used in join queries, provided that only one of the source objects has a rowid. Forum post ab5b077c32636e49 (check-in: d4097364c5 user: dan tags: trunk) | |

| 11:53 | Do not enforce the SQLITE_LIMIT_FUNCTION_ARG limit for internally generated SQL. This prevents problems with statements like ALTER TABLE if the function argument limit is set too low. Forum post 17735aa21f3ddab2. (check-in: 763fdec5b3 user: drh tags: trunk) | |
|
2021-06-28
| ||
| 15:25 | When generating data for a RETURNING clause, avoid assuming cursor number 0 is available for use. (check-in: 4b2c59acce user: dan 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) | |
| 11:21 | Remove a redundant "ANALYZE" line from the ".fullschema" output. (check-in: 7b47f42095 user: drh tags: trunk) | |
| 11:14 | Fix a bug in the ".fullschema" dot-command of the CLI brought to light by check-in [a2ddb89b206c1387] - raising an error on at attempt to access the rowid of a subquery or view. (check-in: 36875827a4 user: drh tags: trunk) | |

|
2021-06-24

| 18:23 | Allow the SQLITE_OPEN_EXCLUSIVE flag in sqlite3_open(). Return the SQLITE_CANTOPEN_EXISTS extended code to indicate that the open failed because the database already exists. (check-in: d091150ff8 user: drh tags: trunk) | |
|
2021-06-23

| 11:12 | Fix a problem handling ORDER BY terms of the form "ORDER BY likely(<integer>)" within window frames. (check-in: 710f75b98b user: dan tags: trunk) | |
|
2021-06-22
| ||
| 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. (check-in: 787c76a865 user: drh tags: trunk) | |
| 18:32 | Add the sqlite3_changes64() and sqlite3_total_changes64() API functions. (check-in: 48fdec22c9 user: dan tags: trunk) | |
| 18:06 | Fix a problem causing sqlite3_changes() to return an incorrect value following a "DELETE FROM tbl" command on an intkey table (because internal b+tree cells were being included in the count). (check-in: f662ff4746 user: dan tags: trunk) | |
| 14:59 | Ensure that the cell array used in balance_nonroot() is always large enough, even if the pages being balanced are corrupt. (check-in: 53f64e83b3 user: dan tags: trunk) | |

| 22:17 | Do not allow an SQLITE_CORRUPT error to mask a prior SQLITE_IOERR in balance_nonroot(). dbsqlfuzz 5e1c86e7f18023f2b9abe3429977d7ea726f50d8 (check-in: 50e818767e user: drh tags: trunk) | |

| 20:20 | Remove unnecessary (redundant) variable initialization from sqlite3BtreeInsert() for a small size reduction and performance increase. (check-in: 70d1836474 user: drh tags: trunk) | |
| 18:35 | The previous check-in is a significant change to btree, so go ahead and increment the version number for the next development cycle. (check-in: 2eb6697051 user: drh tags: trunk) | |
| 18:32 | Split the sqlite3BtreeMovetoUnpacked() routine into two separate routines sqlite3BtreeTableMoveto() and sqlite3BtreeIndexMoveto(), since we usually know the type of btree in advance. This results in less branching and better performance. (check-in: 3b0d34e5e5 user: drh tags: trunk) | |

| 15:36 | Update the "nmakehlp.c" utility program sources associated with the TCL Extension Architecture, obtained from https://core.tcl-lang.org/sampleextension/file. Perhaps this new version will sit better with salmonx's static analyzer (ref1), (ref2). (check-in: 603b851d7d user: drh tags: trunk) | |
| 15:15 | Add NULL checks on all sqlite3_vfs_find(0) calls. This is not strictly necessary. There are no vulnerabilities here. However, adding these checks avoids unnecessary static analyzer complaints. Forum post ce1193be15. (check-in: 272a15b9f4 user: drh tags: trunk) | |
