24 check-ins using file test/where.test version a6bfb5a292

2012-10-03
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: c1f10a2643 user: drh tags: trunk)
00:25
Further attempts to optimize out unnecessary ORDER BY clauses. (check-in: 6744d9a37f user: drh tags: qp-enhancements)
2012-10-02
22:54
Work around an optimization issue with the MSVC compiler for ARM. (check-in: 7d301fdfee 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: abcf6a5d05 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: b0e7b4df6c 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: 545bb33688 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: 351dc8d9ca user: drh tags: trunk)
01:10
Improvements to the wheretrace output. (check-in: 76b2776556 user: drh tags: trunk)
2012-10-01
20:32
Fix harmless compiler warnings. (check-in: 59c2be75ff user: drh tags: trunk)
20:12
Fix several compiler warnings seen with MSVC. (Closed-Leaf check-in: 8b5f617c2a 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: 1262d2f471 user: dan tags: trunk)
17:44
Minor changes to the query planner for improved test coverage. (check-in: c12044df32 user: drh tags: trunk)
12:44
Omit the sqlite3GetReservedNoMutex() routine in build configurations where it is not used. (check-in: f193dbb6b9 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: daebe3bd2d user: drh tags: trunk)
06:50
Ensure that the value returned by xSectorSize() is reasonable (currently defined as between 2^5 and 2^16 bytes) before using it to calculate the amount of padding to add to a wal file. (check-in: 6b4ff83bff user: dan tags: trunk)
2012-09-29
19:10
Improved ORDER BY optimization when outer loops of a join return a single row. (check-in: 62225b4a4c user: drh tags: trunk)
15:45
Disable the bigfile tests on Macs. (check-in: d869eddaf2 user: drh tags: trunk)
14:45
Fix compiler warnings found on Lion. (check-in: fd74d3d917 user: drh tags: trunk)
2012-09-28
20:23
Avoid calling sqlite3BtreeEnter() in a corner case where the corresponding database handle mutex (sqlite3.mutex) may not be held. This prevents a potential deadlock or crash that can occur if the backup API, shared-cache mode and SQLITE_HAVE_CODEC are all in use. (check-in: 89b8c377a6 user: dan tags: trunk)
18:13
Modify the clearCell function to use SQLITE_CORRUPT_BKPT in the one place it was not. (check-in: 472beb306a user: mistachkin tags: trunk)
13:05
Merge the latest trunk changes (especially "PRAGMA busy_timeout" and the ORDER BY query planner optimizations) into the sessions branch. (check-in: 6ca8eae1f8 user: drh tags: sessions)
10:57
Merge the latest trunk changes (PRAGMA busy_timeout and the ORDER BY query planner enhancements) into the apple-osx branch. (check-in: 6a5c59dd7e user: drh tags: apple-osx)
00:44
Query planner enhancements to be more agressive about optimizing out ORDER BY clauses - in particular the query planner now has the ability to omit ORDER BY clauses that span multiple tables in a join. (check-in: 1e874629d7 user: drh tags: trunk)
2012-09-27
23:27
Fix some corner case behavior in the new ORDER BY optimization logic. Remove the SQLITE_OrderByIdx bit from the SQLITE_TESTCTRL_OPTIMIZATIONS mask, since enabling it caused many TH3 tests to fail when the NO_OPT configuration parameter was engaged, and since there really isn't any need to turn that optimization off. The SQLITE_OrderByIdxJoin bit remains. (Closed-Leaf check-in: 98b633717a user: drh tags: qp-enhancements)
