Update the threadtest3 test program so that its output summary is compatible with releasetest.tcl. In threadtest3, do not record errors that contain the string "no such table" as being fatal errors, since they happen sometimes in a race condition in stress1. check-in: 98cb56e2 user: drh tags: trunk
18:07
Fix problems with the "inmemory_journal" permutation. check-in: 79693f04 user: dan tags: trunk

21:10
Remove 'threadtest' as a target on Windows, due to lack of pthreads. Also, change 'fulltest' to 'fulltestonly'. Closed-Leaf check-in: a010c404 user: mistachkin tags: releasetest-refactor
21:03
Fix typo in library object file name. check-in: f49566a7 user: mistachkin tags: releasetest-refactor

19:52
Add the "checksymbols" target to Makefile.in check-in: 5bd73dba user: drh tags: releasetest-refactor
19:40
Rework the test/releasetest.tcl script so that it uses the autoconf makefile instead of the test/releasetest.mk makefile. Also add options like --dryrun and --buildonly. Omit the --makefile option and replace it with --srcdir with the default computed relative to the releasetest.tcl script itself. check-in: 7c85e831 user: drh tags: releasetest-refactor
2014-12-22
22:02
Fix a typo in an evidence mark on a test script. No changes to code. check-in: a08b0c75 user: drh tags: trunk
18:41
Redefine the way PRAGMA data_version works: It continues to change when any other connection commits, including shared-cache connections, but does not change if the local connection commits. check-in: 7a97826f user: drh tags: trunk
2014-12-21
11:56

14:34
Update the PRAGMA data_version command so that it reponse to changes made by a shared-cache database connection, and also to changes made by the same database connection. Add test cases to verify the new behavior. Closed-Leaf check-in: 44ee5383 user: drh tags: data_version_pragma
2014-12-19
20:27

18:49
Simplify the implementation of the "header-value" pragmas (schema_version, user_version, freelist_count, and application_id) by making them more table-driven. check-in: da27a09d user: drh tags: trunk
2014-12-17
15:03
Experimental opimizations to speed up FK constraint CASCADE and SET NULL action processing. check-in: 8c5dd6cc user: dan tags: trunk

Fix the e_walauto.test script so that it works on windows. check-in: 7d092ebb user: drh tags: trunk
00:20
Enhanced "stress2" testing in the threadtest3.c test program. check-in: ae43539e user: drh tags: trunk
00:08
Make sure the sqlite3BtreeCount() routine does not leave index cursors in an inconsistent state, as doing so might result in an assertion fault inside of sqlite3BtreeKey() called from saveAllCursors() if content is deleted out from under the statement that issued the sqlite3BtreeCount() call. check-in: 5b1b6970 user: drh tags: trunk
2014-12-15
20:49
Changes to threadtest3 so that "stress2" is more similar to the SDS stress test. Closed-Leaf check-in: 5648af96 user: dan tags: threadtest3
16:27
Add new test file e_walauto.test. check-in: 62ef4514 user: dan tags: trunk

2014-12-13
17:41
Further enhancements to threadtest3 stress tests. check-in: ba772cff user: dan tags: trunk
2014-12-12
23:17
Add extra tests to threadtest4.c. Fix a benign data race accessing the text encoding using ENC(db). check-in: d7bb7ea4 user: drh tags: trunk
16:39
Add extra tests to threadtest3. check-in: f6bf86f9 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: d8d3e6d0 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: 03c443ea 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: 6bef7ede user: drh tags: threadtest4
00:26
Merge the cell overflow page number cache thread race fix from trunk. check-in: cefad47e 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: b7489f94 user: drh tags: threadtest4
2014-12-11
19:29
Add the threadtest4.c test program. Not yet working. check-in: ec3a7446 user: drh tags: threadtest4

Fix typos in the documentation for sqlite3_table_column_metadata(). No changes to code. check-in: 3528f8dd 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: cf9be419 user: drh tags: trunk
20:13
Add extra tests to e_walckpt.test. check-in: 84f95810 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: 1ba8911c 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: 4f7549ff 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: 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

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

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

20:51
Add support for SQLITE_CHECKPOINT_TRUNCATE. check-in: edda2b9e 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: 6ee08769 user: dan tags: checkpoint-truncate
19:04
Add the SQLITE_CHECKPOINT_TRUNCATE option. check-in: 8e20a434 user: dan tags: checkpoint-truncate

2014-11-28
13:35
Remove the ill-designed "-end" option from the command-line shell. Instead, allow multiple SQL or dot-commands as command-line arguments. Any -cmd commands are processed first, followed by other command-line arguments, for backwards compatibility. check-in: 24fa2e98 user: drh tags: trunk
11:54
Add the -end option to the command-line shell, which forces it to exit after reading prior command-line options (presumably including one or more -cmd options) and without reading standard input. check-in: b59397b1 user: drh tags: trunk
2014-11-27
11:36
Fix a buffer overread during compilation of CREATE VIRTUAL TABLE statements that featured an explicit database name but no virtual table arguments. For example, "CREATE VIRTUAL TABLE main.ft USING fts4". check-in: f095cde5 user: dan tags: trunk
