| 20:39 | Version 3.7.15.1 (check-in: 6b85b767 user: drh tags: release, version-3.7.15.1, branch-3.7.15) | |
| 17:10 | Backport to the 3.7.15 branch the fix to the segfault problem of ticket [a7b7803e8d1e869] which involved the use of "AS" named result columns as logical terms of the WHERE clause. Also, change the version number to 3.7.15.1. (check-in: bae528f4 user: drh tags: branch-3.7.15) | |
| 16:58 | • Edit [0ae142178d5ff874|0ae14217]: Mark "Closed". (artifact: ce1c4fea user: drh) | |

| 15:53 | Proposed fix for ticket [a7b7803e8d1e8699cd8a]. (check-in: 3d0e00c7 user: drh tags: tkt-a7b7803e) | |
| 15:17 | • Fixed ticket [71e333e7]: COLLATE operator inside CHECK constraint fails in shared-cache mode plus 5 other changes (artifact: 5335c947 user: drh) | |

|
2012-12-18
| ||
| 19:36 | Optimize the degenerate case of a FROM clause table name enclosed all by itself inside parentheses. Generate code as if the parentheses did not exist, rather than the old behavior of manifesting the parenthesized table into a transient table. Also, tag every FROM-clause SELECT subquery that is generated by a parenthesized FROM-clause expression using the SF_NestedFrom flag. The new SF_NestedFrom flag is not yet used for anything. (check-in: 7fecced4 user: drh tags: trunk) | |

| 20:57 | Add to the foreign_key_check pragma an extra output column "parent" that contains the name of the parent table for the constraint that failed. (check-in: 97f7f737 user: drh tags: foreign-key-check) | |
| 20:40 | Enhance the error message for "foreign key mismatch" to include the names of the child and parent tables. Begin adding test cases for PRAGMA foreign_key_check. Make sure PRAGMA foreign_key_check gets all necessary table locks. (check-in: 0f996352 user: drh tags: foreign-key-check) | |
| 18:43 | "PRAGMA foreign_key_check" with no argument checks the foreign keys on all tables. (check-in: 57d47423 user: drh tags: foreign-key-check) | |
| 18:05 | Fix an issue with child keys that are not INTEGER PRIMARY KEY referencing INTEGER PRIMARY KEY in the parent. (check-in: 603b695b user: drh tags: foreign-key-check) | |

| 17:54 | Optimize IN operators in the WHERE clause of queries using virtual tables. (check-in: 3d65c703 user: drh tags: trunk) | |
| 17:48 | Remove an unreachable branch. Improvements to comments. (Closed-Leaf check-in: d2fb7619 user: drh tags: vtab-IN-opt) | |
| 15:54 | Merge in all the trunk changes that have occurred since this branch was opened. (check-in: 6d507e4d user: drh tags: vtab-IN-opt) | |
| 15:36 | Fix the virtual table IN optimizer so that it work even if the virtual table implementation leaves the sqlite3_index_info.aConstraintUsage[].omit flag clear for an equality constraint that it intends to use. (check-in: d6e045f8 user: drh tags: vtab-IN-opt) | |
|
2012-12-13
| ||
| 18:57 | Generalize the min/max optimization so that if an appropriate index exists, the index it can be used by any aggregate query that contains only a single max() or min() and does not contain a GROUP BY clause. (check-in: 52e75594 user: drh tags: trunk) | |
| 18:51 | Increase the version number to 3.7.16 in advance of adding new features for the next release. (check-in: 8bcf5f51 user: drh tags: trunk) | |
|
2012-12-12
| ||

| 18:36 | • Edit [cdbfa664839a4095|cdbfa664]: Mark "Closed". (artifact: 34d82def user: drh) | |
| 18:36 | • Edit [0c31a46801746191|0c31a468]: Mark "Closed". (artifact: 0d591ba3 user: drh) | |
|
2012-12-10
| ||
| 22:19 | When an arithmetic operation with two integer operands must give a floating-point answer due to overflow, make sure the answer is not rounded back to integer by affinity. (check-in: bd7aeeb6 user: drh tags: trunk) | |
|
2012-12-08
| ||
| 23:37 | Pull the latest trunk changes into the sessions branch, and in particular the collating-sequence refactorization. (check-in: 4f6d69ae user: drh tags: sessions) | |
| 22:14 | Factor some work out of the index loop of the bestBtreeIndex() routine for a small performance increase. (check-in: 92c9ab56 user: drh tags: trunk) | |
| 21:51 | Refactor collating-sequence handling as a fix for ticket [71e333e7d2e642]. The Expr.pColl field is removed from the Expr object. The COLLATE operator now becomes a separate instance of Expr in the expression tree. The code generator looks up the correct collating function as needed, rather than referring to Expr.pColl. (check-in: 8542e618 user: drh tags: trunk) | |
| 21:36 | Adjustments to the collating-sequence refactoring to facilitate full-coverage testing and to fix some minor issues found by TH3. (Closed-Leaf check-in: cdbfa664 user: drh tags: ticket-71e333e7) | |

| 13:26 | Fix the header comment on the OP_Compare operator. (check-in: 2722f407 user: drh tags: ticket-71e333e7) | |
| 04:10 | Duplicating check constraint expressions prior to code generation is no longer required, and so it is removed. (check-in: 1a9db8dc user: drh tags: ticket-71e333e7) | |
| 03:34 | Veryquick passes all tests now. (check-in: 7b96115e user: drh tags: ticket-71e333e7) | |
| 00:52 | Recognize TK_COLLATE operators that have been transformed into TK_REGISTER. Skip both TK_COLLATE and TK_AS operators when looking for the top of an expression. (check-in: f66c1db2 user: drh tags: ticket-71e333e7) | |
|
2012-12-07
| ||
| 23:23 | Improved error messages when column integers in an ORDER BY clause are out of range. (check-in: bd960d93 user: drh tags: ticket-71e333e7) | |
| 23:10 | For an ORDER BY on a compound SELECT, take the collating sequence from the left-most term of the compound. (check-in: 8e724b38 user: drh tags: ticket-71e333e7) | |

| 22:18 | Fix a long-standing issue with the distinct-as-aggregate optimization that only expressed when the new collating-sequence logic is turned on. (check-in: 0aaf52a3 user: drh tags: ticket-71e333e7) | |
| 21:02 | Fix the processing of ORDER BY clauses with COLLATE terms on compound queries. 52 veryquick test failures remain. (check-in: 49654453 user: drh tags: ticket-71e333e7) | |
| 20:31 | Many more tests are passing. Only about 100 failures remain in veryquick. (check-in: f9fa7581 user: drh tags: ticket-71e333e7) | |
| 18:38 | Some errors in veryquick resolved. Many more to go. (check-in: 972443b4 user: drh tags: ticket-71e333e7) | |
| 16:03 | • Edit [7fafab12e4c0c832|7fafab12]: Edit check-in comment. (artifact: ac6ff8f2 user: drh) | |
| 14:02 | Veryquick now runs to completion without segfaulting or asserting. But there are still lots of errors. (check-in: 7fafab12 user: drh tags: ticket-71e333e7) | |
|
2012-12-06
| ||
| 21:16 | Remove the Expr.pColl field and compute the collating sequence as it is needed. This fixes the test script "shared9.test", though there is still a memory leak. And there are other problems. Consider this a work-in-progress. (check-in: fd011cb2 user: drh tags: ticket-71e333e7) | |
| 19:01 | Add the SQLITE_FCNTL_TEMPFILENAME file control that asks the underlying VFS to return a new temporary filename. Per request from NSS team at Mozilla. (check-in: 1a63b1d5 user: drh tags: trunk) | |
| 15:15 | Add a test case that demonstrates ticket [71e333e7d2e642]. (check-in: cc6e0785 user: drh tags: ticket-71e333e7) | |
| 15:05 | • New ticket [71e333e7] COLLATE operator inside CHECK constraint fails in shared-cache mode. (artifact: 7f899f32 user: drh) | |

|
2012-12-05

| 14:31 | Make sure memory is freed using a routine that is compatible with the routine used to allocate the memory. The SQLITE_MEMDEBUG compile-time option enforces this. (check-in: 9f6c6885 user: drh tags: trunk) | |
|
2012-12-04
| ||
| 11:03 | Fix a harmless compiler warning. (check-in: 12693deb user: drh tags: trunk) | |

| 00:59 | Improvements to the 'tcl' shell output mode. Escape doublequotes, set separator to space when mode is set, and skip separator after final column. (check-in: 487ba753 user: drh tags: trunk) | |
| 00:58 | • Edit [41fd9dd29034b226|41fd9dd2]: Mark "Closed". (artifact: 7e1a4ee1 user: drh) | |

|
2012-12-03
| ||
| 19:42 | Remove an unreachable condition. Replace it with an assert(). (check-in: 7d5fc1a3 user: drh tags: trunk) | |
| 17:04 | Make sure that the optimization that set the maximum column that will be used on a particular query does not mistakenly change an opcode other than OP_OpenRead or OP_OpenWrite. In particular, make sure it does not overwrite the P4 field of an OP_SorterOpen. (check-in: b0c1ba65 user: drh tags: trunk) | |
