61 check-ins using file src/pragma.c version d54cdd40b6

2014-12-12
16:39
Add extra tests to threadtest3. (check-in: f6bf86f907 user: dan tags: trunk)
01:27
Add new tests to the threadtest4.c program. Fix a long-standing data race in WAL mode for shared-cache. (check-in: d8d3e6d04c user: drh tags: trunk)
00:52
Remove the KeyInfo cache (for now - perhaps we will add it back in later - or maybe not since it provides negligible benefit but adds a lot of complexity and thread-safety risk). Add a mutex to ATTACH to deal with a data race. (check-in: 03c443eaf2 user: drh tags: trunk)
00:40
Make sure the Btree mutex is held when setting the locking mode and the secure delete flag when attaching a shared-cache database. (Closed-Leaf check-in: 6bef7ede2b user: drh tags: threadtest4)
00:26
Merge the cell overflow page number cache thread race fix from trunk. (check-in: cefad47ec2 user: drh tags: threadtest4)
00:20
Fix a bug in the threadtest4.c program. Remove the keyinfo cache as it provides minimal performance improvements, and then only at SQL preparation time, not at runtime, and it has problems with data races in shared-cache mode. We might later add the keyinfo cache back but only enable it when shared-cache mode is off. (check-in: b7489f9451 user: drh tags: threadtest4)
2014-12-11
19:29
Add the threadtest4.c test program. Not yet working. (check-in: ec3a74469c user: drh tags: threadtest4)
16:38
Fix a race condition to do with very large index keys in shared-cache mode. (check-in: fc157dd7f1 user: dan tags: trunk)
15:27
Fix a typo in the documentation for sqlite3_threadsafe(). (check-in: 258e747bb7 user: drh tags: trunk)
04:49
Update a comment. (check-in: e0e102a0bd user: mistachkin tags: asciiMode)
03:29
Rename a structure member to improve code clarity. (check-in: d48eda16ef user: mistachkin tags: asciiMode)
03:25
Remove an unused structure member. (check-in: d8404340cb user: mistachkin tags: asciiMode)
03:20
Further simplify shell mode changes. (check-in: cf9c6e7eea user: mistachkin tags: asciiMode)
03:12
Simplify and cleanup the implementation of the new ASCII mode for the shell. (check-in: 66a28f7aba user: mistachkin tags: asciiMode)
02:28
Merge updates from trunk. (check-in: 5b5d3e4d0d user: mistachkin tags: asciiMode)
2014-12-10
20:57
Fix a typo causing a test error in e_walhook.test. (check-in: d9f916ba09 user: dan tags: trunk)
20:29
Add new test file e_walhook.test. (check-in: 2eb6d3e4fb user: dan tags: trunk)
17:34
Revise mutex handling by the sqlite3_win32_reset_heap() function. (check-in: eacb3b7baa user: mistachkin tags: trunk)
04:58
Fix typos in the documentation for sqlite3_table_column_metadata(). No changes to code. (check-in: 3528f8dd39 user: drh tags: trunk)
2014-12-09
22:24
Fix the sqlite3_table_column_metadata() routine so that it gives the correct answer for the "rowid" column in a WITHOUT ROWID table. Enhance it so that it can be used to check for the existence of a table by setting the column name parameter to NULL. The routine is now included in the build by default, even without the SQLITE_ENABLE_COLUMN_METADATA compile-time option. (check-in: cf9be419a1 user: drh tags: trunk)
20:13
Add extra tests to e_walckpt.test. (check-in: 84f9581019 user: dan tags: trunk)
19:16
Lower the default SQLITE_SORTER_PMASZ value back to 10, where it has been for the past couple of releases. Applications that need a larger value can set one. (check-in: 1ba8911c18 user: drh tags: trunk)
19:07
Make the sqlite3_table_column_metadata() interface available by default and without requiring the SQLITE_ENABLE_COLUMN_METADATA compile-time option. Other sqlite3_column_* interfaces that have a run-time penalty even if they are unused still require the SQLITE_ENABLE_COLUMN_METADATA option at compile-time. (check-in: 4f7549ff92 user: drh tags: trunk)
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: 75a803e694 user: drh tags: trunk)
14:54
Merge the KeyInfo cache mutex fix from trunk. (check-in: f0940c73bd user: drh tags: sessions)
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: b05340fe3c user: drh tags: trunk)
04:26
Fix harmless compiler warning. (check-in: e97b7a8b4d user: mistachkin tags: trunk)
2014-12-08
20:29
Add extra tests to e_walckpt.test. (check-in: d6832aa24c user: dan tags: trunk)
20:20
Add missing mutex calls around a call to sqlite3SchemaGet() within sqlite3_open(). (check-in: 4541589954 user: dan tags: trunk)
18:08
Add a missing mutex around calls to clear the KeyInfo cache when closing a database connection. (check-in: 7047ce32a2 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: 6aeece19a2 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: dd1dd4451f user: drh tags: trunk)
2014-12-05
21:18
Avoid a potential NULL pointer deference in the sqlite3_stmt_scanstatus() logic. (check-in: 42d44adc13 user: drh tags: trunk)
21:04
Fix a buffer overread that might occur in analyze.c if SQLITE_ENABLE_STAT4 was defined. (check-in: c1ae1268b9 user: dan tags: trunk)
20:46
Add new test file e_walckpt.test. Still some tests to come. (check-in: e4db3db3a6 user: dan tags: trunk)
20:05
Merge the fix for the shared-cache KeyInfo cache bug from trunk. (check-in: 5a73da6a30 user: drh tags: sessions)
19:50
Make sure the WhereTerm objects are fully zeroed when they are allocated. (check-in: fdb667335c 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: 7ed3346e8c 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: adca7688de 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: 68b23c3d41 user: drh tags: collseq-checking)
14:34
Improved comment on the sharedB.test test script. (Closed-Leaf check-in: 71f589e3f8 user: drh tags: fix-stale-keyinfo-cache)
14:07
Test case demonstrating the problem described by ticket [e4a18565a36884b00edf]. (check-in: ffea3e905a 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: 651ed97de1 user: drh tags: fix-stale-keyinfo-cache)
00:41
Import from trunk the fix the "test" target on the autoconf and MSVC makefiles and some minor compiler warning fixes. (check-in: c9f20eb2fb user: drh tags: sessions)
00:32
Fix compiler warnings. (check-in: e9955c0e14 user: drh tags: trunk)
00:17
Fix the autoconf and MSVC makefiles, which have been broken for nearly a month. :-( (check-in: 520c2b838d user: drh tags: trunk)
2014-12-04
23:35
Incorporate the SQLITE_CHECKPOINT_TRUNCATE enhancement and a couple of obscure bug fixes from trunk. (check-in: 34ffa3b3c0 user: drh tags: sessions)
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: 0d3aef97eb 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: 1461d543ac 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: 6f6fcbe473 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: 1e2bc484f8 user: drh tags: trunk)
14:01
Fix comment typos reported on the mailing list. No changes to code. (check-in: 93a71c9f05 user: drh tags: trunk)
04:50
Add an implementation mark and fix a comment describing the OP_Checkpoint opcode. (check-in: 7475b90c55 user: drh tags: trunk)
2014-12-03
19:25
Add evidence marks and assert()s used as evidence for checkpoint requirements. (check-in: b2da8afc76 user: drh tags: trunk)

20:51
Add support for SQLITE_CHECKPOINT_TRUNCATE. (check-in: edda2b9e7a user: drh tags: trunk)
19:35
When attempting to restart a wal file, make any required calls to sqlite3_randomness() before waiting on or checking for wal file readers. This restores the behaviour exhibited by the trunk. (Closed-Leaf check-in: 6ee08769f0 user: dan tags: checkpoint-truncate)
19:04
Add the SQLITE_CHECKPOINT_TRUNCATE option. (check-in: 8e20a43419 user: dan tags: checkpoint-truncate)
