24 check-ins using file src/sqlite.h.in version 6ec65432

15:12
Add the SQLITE_REVERSE_UNORDERED_SELECTS compile-time option that causes the "PRAGMA reverse_unordered_selects" setting to be on by default. check-in: 75a803e6 user: drh tags: trunk
14:42
Increase the default minimum PMA size for multi-threaded sorting from 10x the page size to 250x the page size. Provide the SQLITE_SORTER_PMASZ compile-time option to change this default. check-in: b05340fe user: drh tags: trunk
04:26
Fix harmless compiler warning. check-in: e97b7a8b user: mistachkin tags: trunk
2014-12-08
20:29
Add extra tests to e_walckpt.test. check-in: d6832aa2 user: dan tags: trunk
20:20
Add missing mutex calls around a call to sqlite3SchemaGet() within sqlite3_open(). check-in: 45415899 user: dan tags: trunk
18:08
Add a missing mutex around calls to clear the KeyInfo cache when closing a database connection. check-in: 7047ce32 user: drh tags: trunk
2014-12-06
14:56
Avoid accessing a single uninitialized byte when moving a rare 3-byte cell from an internal page to a leaf. This was not actually causing a problem, just a valgrind warning. check-in: 6aeece19 user: dan tags: trunk
02:05
Fix a (harmless) uninitialized variable reference in b-tree balancing for auto-vacuumed tables with overflow pages. check-in: dd1dd445 user: drh tags: trunk
2014-12-05
21:18
Avoid a potential NULL pointer deference in the sqlite3_stmt_scanstatus() logic. check-in: 42d44adc user: drh tags: trunk
21:04
Fix a buffer overread that might occur in analyze.c if SQLITE_ENABLE_STAT4 was defined. check-in: c1ae1268 user: dan tags: trunk
20:46
Add new test file e_walckpt.test. Still some tests to come. check-in: e4db3db3 user: dan tags: trunk
19:50
Make sure the WhereTerm objects are fully zeroed when they are allocated. check-in: fdb66733 user: drh tags: trunk
15:31
The KeyInfo cache must be cleared before closing the btree, not after. Revised fix for ticket [e4a18565a36884b00edf]. check-in: 7ed3346e user: drh tags: trunk
14:44
When closing a (shared-cache) database connection, be sure to clear out all KeyInfo objects cached on Index objects. Fix for ticket [e4a18565a36884b00edf]. check-in: adca7688 user: drh tags: trunk
14:36
Add code to check the validity of CollSeq objects during runtime. This code was not able to detect anomalies such as came up as a result of ticket [e4a18565a36884b00edf66541f38c693827968ab] so it is put into a branch for historical reference, with the intent of leaving it out of trunk. Closed-Leaf check-in: 68b23c3d user: drh tags: collseq-checking
14:34
Improved comment on the sharedB.test test script. Closed-Leaf check-in: 71f589e3 user: drh tags: fix-stale-keyinfo-cache
14:07
Test case demonstrating the problem described by ticket [e4a18565a36884b00edf]. check-in: ffea3e90 user: drh tags: fix-stale-keyinfo-cache
05:38
When closing a (shared-cache) database connection, be sure to clear out all KeyInfo objects cached on Index objects. Proposed fix for ticket [e4a18565a36884b00edf]. check-in: 651ed97d user: drh tags: fix-stale-keyinfo-cache
00:32
Fix compiler warnings. check-in: e9955c0e user: drh tags: trunk
00:17
Fix the autoconf and MSVC makefiles, which have been broken for nearly a month. :-( check-in: 520c2b83 user: drh tags: trunk
2014-12-04
21:54
Make sure that a DISTINCT query with an ORDER BY works correctly even if it uses a descending index. Fix for ticket [c5ea805691bfc4204b1cb9e]. check-in: 0d3aef97 user: drh tags: trunk
20:24
Performance enhancement for single-table queries with many OR-connected WHERE clause terms and multiple indexes with the same left-most columns. check-in: 1461d543 user: drh tags: trunk
16:27
If a table is the right operand of a LEFT JOIN, then any column of that table can be NULL even if that column has a NOT NULL constraint. Fix for ticket [6f2222d550f5b0ee7ed]. check-in: 6f6fcbe4 user: drh tags: trunk
15:02
Clarification of the meaning of the second parameter to the busy-handler callback. No changes to code. check-in: 1e2bc484 user: drh tags: trunk
