| 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

| 20:13 | Experimental opimizations to speed up FK constraint CASCADE and SET NULL action processing. Requires further testing. check-in: 35a20a5f user: dan tags: experimental-fk-actions | |
| 12:46 | 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 | |

| 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 | |
|

|
2014-12-09
| ||
| 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 | |

|
2014-12-06
| ||
| 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 | |

| 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 | |

| 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 | |

| 21:37 | Always reinitialized the Index.bUnordered and Index.noSkipscan flags before rereading the sqlite_stat1 table, even if SQLITE_ENABLE_STAT4 is defined. check-in: 1e1221fc user: drh tags: trunk | |
| 19:52 | Fix an error in the comments from the previous check-in. check-in: 9660ce54 user: drh tags: trunk | |
| 18:50 | Deploy heuristics (well-commented) to better estimate how much unindexed terms in the WHERE clause filter the number of output rows from a single table. check-in: 22165994 user: drh tags: trunk | |
| 12:22 | Remove a redundant test case (probably a copy/paste error). Add an assert() to where.c to ensure that automatic indexes do not have there output row counts adjusted downward by supplementary constraints. check-in: eea47933 user: drh tags: trunk | |

| 14:05 | Add an ALWAYS on an always-true branch in wal.c. Fix the ANALYZE command so that it resets the "unordered" and "noskipscan" flags on indices when reloading the sqlite_stat1 table. check-in: 9ed97a85 user: drh tags: trunk | |
|
2014-11-18
| ||
| 21:54 | Adding the "noskipscan" token to an sqlite_stat1.stat field prevents an index for being used with the skip-scan algorithm. check-in: 4461bf04 user: drh tags: trunk | |
| 21:45 | Allow an automatic index to be used if the only uses of declared indexes for the same loop use the skip-scan algorithm. check-in: c52f7971 user: drh tags: trunk | |

| 20:22 | Fix a bug in the sqlite3TripAllCursors() routine that prevents it from reporting errors. It is unknown at this time whether or not this omission can result in any incorrect result in an actual query. check-in: 2896f264 user: drh tags: trunk | |
| 20:16 | Update a couple of test cases to account for the fact that ROLLBACK does not always abort all running SELECT statements. check-in: abccda76 user: drh tags: trunk | |
