23 check-ins using file src/vdbeaux.c version 521b954f

2011-02-11
20:52
Skip flattening if subquery has LIMIT and outer query is DISTINCT. Fix for ticket [752e1646fc]. (check-in: 55973999 user: shaneh tags: trunk)
06:59
Fix a bug in the new WHERE-clause processing that tries to use an index to resolve IS NOT NULL constraints when SQLITE_ENABLE_STAT2 is defined. The bug could cause memory overruns and segfaults. The bug was new to the code and has not appeared in an official release. Found during structural testing. (check-in: a5c36b9f user: drh tags: trunk)
03:56
Allow an index paired with an IS NULL constraint to be used for sorting under the condition that the index be treated as a non-unique index. (check-in: d78949fc user: drh tags: trunk)
02:43
Disable unused NULL tests when SQLITE_ENABLE_STAT2 is not in use. (check-in: 5ecd1178 user: drh tags: trunk)
2011-02-10
21:08
Add .testctrl option to CLI. (check-in: f85afa0e user: shaneh tags: trunk)
18:56
Split the documentation for sqlite3_wal_checkpoint_v2() and its constants onto separate pages. No changes to code. (check-in: 0ef8ffd1 user: drh tags: trunk)
17:46
Prevent a segfault when automatic indices try to use a column with an unknown collating function. Ticket [77aa3b1e6592582e38605d36]. This check-in also removes some stray \r characters unrelated to the problem. (check-in: f01030a0 user: drh tags: trunk)
00:08
Refactor the cost function in the query planner. Give extra cost (thus reduce likelihood of selection) to full table scans. (check-in: 878da276 user: drh tags: trunk)
2011-02-09
19:55
Make sure code *compiles* with each OMIT and ENABLE option. Mostly changes to test modules. (check-in: 7cc515ed user: shaneh tags: trunk)
18:19
Do not report corruption if the the db size header field is greater than the file size on disk unless the two change-counter header fields are identical. Fix for ticket [89b8c9ac54]. (check-in: 00c4596f user: dan tags: trunk)
15:25
Update Makefile.in for fts3_aux changes. (check-in: 38b7cb33 user: shaneh tags: trunk)
03:04
Use macros to define the relative costs of search and seek operations when computing costs in the query planner. Current constants seems wrong and need to be fixed, but doing so will alter test results. Need more experimentation to determine accurate relative costs. (check-in: 5f2ec44b user: drh tags: trunk)
03:03
Simplifications to the sqlite3_wal_checkpoint_v2() logic. (check-in: 652b8835 user: drh tags: trunk)
2011-02-07
23:56
Cleanup to the OP_Checkpoint opcode. (check-in: f611a5a8 user: drh tags: trunk)
16:24
Fix some test cases in walfault.test. Extend one test case to restore code coverage. Add wal5.test to the "coverage-wal" permutation. (check-in: f83b07ac user: dan tags: trunk)
15:12
Change blocking-checkpoint tests so that they run once using "PRAGMA wal_checkpoint" and once using calls to sqlite3_wal_checkpoint_v2(). Also fix edge cases surrounding the output variables set by wal_checkpoint_v2(). (check-in: 5a4b6652 user: dan tags: trunk)
2011-02-05
15:47
Ensure fts4aux can handle a table name in single or double quotes as a constructor argument. (check-in: 929d62e4 user: dan tags: trunk)
14:37
Add test cases for fts4aux. Fix a bug affecting fts3 tables with multiple columns. (check-in: dc511e60 user: dan tags: trunk)
2011-02-04
18:56
Change fts4aux to (additionally) report on term frequency in individual columns of an fts table. (check-in: 3996f92a user: dan tags: trunk)
14:28
Significant changes have occurred since the 3.7.5 release so go ahead and increase the version number to 3.7.6. (check-in: 999c915a user: drh tags: trunk)
06:36
Merge the stat2 query planner enhancements into the trunk. (check-in: 499edcbc user: drh tags: trunk)
05:47
If a deferred foreign key constraint fails on a statement that is not part of a larger transation, make sure that the statement fully ends so that subsequent invocations of the same statement will not pass the constraint because they think the transaction is not closed. This is a merge of the deferred-fk-quirk branch together with a test case. (check-in: 2f94d462 user: drh tags: trunk)
2011-01-24
16:00
Ensure that if a deferred FK constraint is violated by a statement that creates its own implicit transaction, the statement is not an "active-write" after sqlite3_step() returns. (Closed-Leaf check-in: 8063197e user: dan tags: deferred-fk-quirk)
