Add a single test case to fts4unicode.test to verify that title-case maps to lower case. Leaf check-in: 46f7c930 user: drh tags: branch-3.7.15

Version 3.7.15.2 check-in: c0e09560 user: drh tags: version-3.7.15.2, branch-3.7.15
11:44
Fix an over-aggressive optimization of ORDER BY on a three-way join where the second table is UNIQUE and the ORDER BY occurs on the third table. Ticket [c997b11c4d53a2ee]. check-in: 3d0609c9 user: drh tags: branch-3.7.15
2012-12-19
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
Fix the segfault problem of ticket [a7b7803e8d1e869] which involved the use of "AS" named result columns as logical terms of the WHERE clause. check-in: b3c9e8f8 user: drh tags: trunk
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
15:53
Proposed fix for ticket [a7b7803e8d1e8699cd8a]. check-in: 3d0e00c7 user: drh tags: tkt-a7b7803e
13:41
Add commentary to the ExprList object to explain how zSpan is overloaded. Add test cases for the new name resolution functionality. check-in: 3e7d84db user: drh tags: name-resolution-fix
02:36
Better resolution of table and column names in joins where some of the terms of the FROM clause are parenthesized. check-in: 7344e791 user: drh tags: name-resolution-fix
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
16:07
Resolve names in FROM-clause subqueries prior to resolving names in the result set expressions of a SELECT statement. check-in: 9b67c633 user: drh tags: trunk
13:12
Remove old commented-out code from parse.y. Fix some over-length source lines in parse.y. No logical changes. check-in: 7e30c021 user: drh tags: trunk
11:59
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. This causes the subsequent rollback operation to use the in-memory journal. Fix for [df678d738adb]. check-in: 8183d8d7 user: dan tags: trunk
2012-12-14
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
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
Attempt to further generalize the min/max optimization so that, if an appropriate index exists, it can be used by any aggregate query that contains only a single aggregate of the form max(colname) or min(colname) and does not contain a GROUP BY clause. Closed-Leaf check-in: 7280e14c user: dan tags: minmax-opt
2012-12-12
14:30
Allow the error message from "PRAGMA integrity_check" to be longer than 20,000 bytes. check-in: 120c82d5 user: drh tags: trunk
13:36
Version 3.7.15 check-in: cd0b37c5 user: dan tags: trunk, release, version-3.7.15
2012-12-11
19:40
Update requirements marks and test cases for multi-VALUE INSERT and to fix typos in requirements text. check-in: 81d9ee0f user: drh tags: trunk
19:10
Fix a typo in a comment that is used to generate documentation. No changes to code. check-in: e38adb60 user: drh tags: trunk
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
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
14:16
Make sure WHERE clause constraints A=B and B=A work the same even with COLLATE clauses. check-in: b3f53668 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
