19:41
Bug fixes in the ORDER BY optimizer. (check-in: 301bbee4 user: drh tags: qp-enhancements)
18:23
Continued refactoring of the ORDER BY optimization logic. This check-in is close to working, but it still has issues. A few test cases fail. (check-in: adbdc663 user: drh tags: qp-enhancements)

2012-10-06
03:48
Changes for WinRT compatibility. Also, allow version resource compilation and embedding to be disabled at compile-time. (check-in: 4b0facc1 user: mistachkin tags: trunk)
2012-10-05
19:43
Fix a problem in shared-cache mode where a COMMIT statement might cause a busy-handler belonging to a shared-cache connection other than the current writer to be invoked. (check-in: e0c889d6 user: dan tags: trunk)
17:44
Merge the shared-cache related fixes from the shared-cache-fix branch to the trunk. (check-in: 698ec776 user: dan tags: trunk)
17:18
Add a test for the collation-sequence/CHECK constraint problem fixed by the previous commit. (Closed-Leaf check-in: 82b6aa77 user: dan tags: shared-cache-fix)
16:30
Fix a problem with shared-cache mode and CHECK constraints causing one db handle to invoke a collation sequence function registered with another. (check-in: c2c776ab user: dan tags: shared-cache-fix)
14:43
Consolidate all occurrences of the "no such collation sequence" error message into a single spot. (check-in: 8ea67522 user: drh tags: trunk)
07:36
Rename a tool batch file subroutine to avoid confusion about its purpose. (check-in: 43155b15 user: mistachkin tags: trunk)
2012-10-04
19:33
Shared-cache mode fixes for views and virtual tables. (check-in: 2b370dea user: dan tags: shared-cache-fix)
12:10
Yet another refactoring of ORDER BY logic in the query planner. This particular check-in works mostly, but still has a few minor issues. (check-in: 8f448745 user: drh tags: qp-enhancements)
2012-10-03
20:25
Merge updates from trunk. (check-in: 1138815c user: mistachkin tags: configReadOnly)
18:09
Fix an out-of-order memset() that occurs before all variable declarations are finished. Also fix a line that exceeds the 80-character line length limit. (check-in: ba2f492f user: drh tags: trunk)
12:56
Update the query planner to recognize more cases where ORDER BY clauses can be optimized out. Add test cases to verify correct behavior of the ORDER BY optimization when the covering-index-scan optimization is disabled. Fix a harmless compiler warning in the TCL interface. (check-in: 956e4d7f user: drh tags: trunk)
12:38
Fix a query planner problem that only occurs when covering-index-scan is disabled. Fix to tests whose output changed due to the new and more aggressive ORDER BY optimization. (Closed-Leaf check-in: 0f9bb901 user: drh tags: qp-enhancements)
11:02
Fix the TCL interface so that SQL functions implemented in TCL honor the "nullvalue" setting. Also remove from the TCL interface some unused legacy UTF8 translation code left over from SQLite2. (check-in: c1f10a26 user: drh tags: trunk)
00:25
Further attempts to optimize out unnecessary ORDER BY clauses. (check-in: 6744d9a3 user: drh tags: qp-enhancements)
2012-10-02

Work around an optimization issue with the MSVC compiler for ARM. (check-in: 7d301fdf user: mistachkin tags: trunk)
15:19
More lenient handling of ORDER BY optimization in joins with mixed ASC/DESC. This is a better and less restrictive fix for the problem addressed by the previous check-in. (check-in: abcf6a5d user: drh tags: trunk)
14:11
Only continue an ORDER BY optimization into inner loops if the equality constraints on the inner loop match terms of an outer ordered index that are actually used by the ORDER BY clause. (check-in: b0e7b4df user: drh tags: trunk)
01:46
Factor an invariant out the loop termination condition for the ORDER BY satisfied-by-index analyzer routine. (check-in: 545bb336 user: drh tags: trunk)
01:25
Make sure the outer loop cursor numbers are recorded in time for them to be used by the ORDER BY optimizer. (check-in: 351dc8d9 user: drh tags: trunk)
01:10
Improvements to the wheretrace output. (check-in: 76b27765 user: drh tags: trunk)
2012-10-01
20:32
Fix harmless compiler warnings. (check-in: 59c2be75 user: drh tags: trunk)
20:12
Fix several compiler warnings seen with MSVC. (Closed-Leaf check-in: 8b5f617c user: mistachkin tags: msvcWarnings)
18:44
Add SQLITE_FCNTL_BUSYHANDLER. Invoked to provide access to the busy-handler callback to custom VFS implementations. (check-in: 1262d2f4 user: dan tags: trunk)
17:44
Minor changes to the query planner for improved test coverage. (check-in: c12044df user: drh tags: trunk)
12:44
Omit the sqlite3GetReservedNoMutex() routine in build configurations where it is not used. (check-in: f193dbb6 user: drh tags: trunk)
12:16
Make sure the size parameter to read and write VFS methods in the unix VFS do not become too big or go negative. This was not actually possible in the current code. The checks are added to make sure some future bug does not make it possible. (check-in: daebe3bd user: drh tags: trunk)
