16:32
A couple more test cases. Closed-Leaf check-in: 0ae14217 user: drh tags: tkt-a7b7803e
16:25
Additional test cases involving the use of a result column specified by its "AS" name as a logical term of the WHERE clause. Ticket [a7b7803e8d1e8699cd]. check-in: d7cc364e user: drh tags: tkt-a7b7803e

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

On atomic-write capable systems, if copying the contents of an in-memory journal to disk fails, close the (on disk) journal file before returning the error to the caller.

2012-12-17
22:32

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

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
16:37

Closed-Leaf check-in: 7280e14c user: dan tags: minmax-opt
2012-12-12

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
10:22
Modify releasetest.tcl so that it runs the "checksymbols" test on a build without SQLITE_DEBUG defined. If SQLITE_DEBUG is defined, the sqlite3WhereTrace variable causes the test to fail. check-in: 75e545a9 user: dan tags: trunk
09:08
Remove a reference to JumpOnce from a comment in vdbe.c. No code changes. check-in: ee662c03 user: dan 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.

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

06:46
Merge updates from trunk. check-in: e65db42c user: mistachkin tags: configReadOnly
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

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
19:28
Ensure the VerifyCookie sub-routine has been run before the database is accessed in an obscure case. Fix for ticket [d6b36be38]. check-in: 2d5f37c9 user: dan tags: trunk
18:38
Some errors in veryquick resolved. Many more to go. check-in: 972443b4 user: drh tags: ticket-71e333e7
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
10:55
Do not run test file malloc3.test as part of the inmemory_journal permutation. Explanation is in a comment at the top of malloc3.test. check-in: df1827b1 user: dan tags: trunk
09:08

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
20:27

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
11:30

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
2012-12-01
