| 17:49 | Add a few more test cases to walvfs.test. check-in: 14a64df3 user: dan tags: trunk | |
| 16:57 | Avoid an "uninitialized value read" problem in fts5 that can occur with a corrupt database. check-in: 6cae81cd user: dan tags: trunk | |
| 16:04 | Fix a problem with handling corrupt databases in the fts5 integrity-check function. check-in: 9bad745d user: dan tags: trunk | |

| 11:17 | Fix a typo in a comment that is used to generate session documentation. check-in: a1f50d57 user: drh tags: trunk | |
| 00:15 | Increase the number of parameters to sqlite3WhereCodeOneLoopStart() to encourage the compiler to inline that routine within sqlite3WhereBegin(). This gives a performance improvement. check-in: 3c2ad0e9 user: drh tags: reuse-subqueries | |
|
2018-12-24
| ||
| 20:21 | Improvements to EXPLAIN QUERY PLAN formatting. The MULTI-INDEX OR now shows a separate "INDEX" subtree for each index. SCALAR SUBQUERY entries provide a subquery number that is related back to the .selecttrace output. check-in: 7153552b user: drh tags: reuse-subqueries | |
| 20:00 | Add a few more test cases to walfault2.test and walvfs.test. check-in: 3873941c user: dan tags: trunk | |
| 19:59 | Change another fts5 assert() that may fail with a corrupt database to an assert_nc(). check-in: d9653380 user: dan tags: trunk | |
| 18:51 | Add test cases to test file walvfs.test. check-in: d697f6f3 user: dan tags: trunk | |
| 18:10 | Always include OP_Explain opcodes in the bytecode when SQLITE_DEBUG is enabled. check-in: d8c1235c user: drh tags: trunk | |
| 15:22 | Copy some extra test infrastructure from the mutexfree-shmlock branch to trunk. check-in: 883337ff user: dan tags: trunk | |
| 14:30 | Restore a line of code that was previously commented out for debugging. check-in: e53781f5 user: drh tags: reuse-subqueries | |
| 13:34 | Change the way a comparison used to detect corrupt databases in fts3 is done to avoid potential pointer overflow in 32-bit builds. check-in: 95a9a39f user: dan tags: trunk | |
| 12:09 | Do not generate subroutines for non-static SELECT and EXISTS expressions. Fix up some test cases to account for the minor changes in EXPLAIN QUERY PLAN output. check-in: 06de44ec user: drh tags: reuse-subqueries | |
| 11:55 | Prevent the use of subroutines to implement the RHS of IN operators within CHECK constraints. check-in: 6b24d3fb user: drh tags: reuse-subqueries | |
| 02:34 | Experimental code that tries to put the computation of subqueries inside a subroutine, and reuse that subroutine if the same subquery is evaluated more than once. Current code does not work for CHECK constraints. check-in: 6c44838a user: drh tags: reuse-subqueries | |
|
2018-12-23
| ||
| 21:27 | Split the code generation for the RHS of IN operators and for SELECT and EXISTS expressions into two separate subroutines, because there is now little commonality between those to functions. This is intended to help make the code easier to read and maintain. check-in: 2b6494b1 user: drh tags: trunk | |

| 20:32 | Improve the coverage of wal.c provided by the "coverage-wal" test permutation. check-in: 62314851 user: dan tags: trunk | |
| 19:54 | Catch another case of a corrupted structure record in fts5. check-in: fb17fea4 user: dan tags: trunk | |
| 19:09 | Change a faulty assert() in fts5 that could fail on a corrupt db to an if() statement. check-in: 1daaba9f user: dan tags: trunk | |
| 16:14 | Fix one more instance of excess whitespace in test result strings. check-in: c064964d user: drh tags: trunk | |
| 15:46 | Remove unnecessary whitespace from testcase result strings. check-in: ad70f03c user: drh tags: trunk | |
| 15:21 | Fix an assert() in fts5 that could fail with a corrupt database. check-in: 83935b95 user: dan tags: trunk | |
| 13:34 | Fix a "jump or move depends on uninitialized value" valgrind error that could occur in fts5 when dealing with a corrupt database. check-in: 3518c09b user: dan tags: trunk | |
| 09:39 | Avoid a left-shift of a negative value (undefined behaviour) when dealing with a corrupt database in fts3. check-in: b851d124 user: dan tags: trunk | |
| 07:16 | Fix cut-and-paste error in test file fts4umlaut.test. check-in: cad5da1b user: dan tags: trunk | |
| 01:13 | Do not all REPLACE to sneak a NULL value into a NOT NULL column. Detect that situation and ABORT instead. Fix for ticket [e6f1f2e34dceeb1ed61531c7e98]. check-in: db8d1d12 user: drh tags: trunk | |
| 00:34 | The OP_Eq and OP_Ne operators have a special P5 value SQLITE_NOTNULL that asserts that the values are not null. Except that is not always true for a corrupt database. Adjust the assert() and add a testcase() to make this point clear. check-in: a3fdb2c7 user: drh tags: trunk | |
|

| 22:11 | Update the dbtotxt utility program so that it does not output characters that are special to TCL, thus making the output of dbtotxt easier to insert into test scripts. check-in: 48438bb3 user: drh tags: trunk | |
| 22:08 | Improved detection of shadow table corruption in RTREE. check-in: b39bf435 user: drh tags: trunk | |
| 20:18 | Add new sqlite3_prepare_v3() flag SQLITE_PREPARE_NO_VTAB, for preparing statements that are not allowed to use any virtual tables. Use this to prevent circular references in triggers on virtual table shadow tables from causing resource leaks. check-in: da587d18 user: dan tags: trunk | |
| 19:55 | Use SQLITE_PREPARE_NO_VTAB in rtree as well. Closed-Leaf check-in: 82a2ae71 user: dan tags: prepare-no-vtab | |
| 19:30 | Add tests for the use of SQLITE_PREPARE_NO_VTAB in fts5. check-in: 19996120 user: dan tags: prepare-no-vtab | |
| 19:29 | Add new sqlite3_prepare_v3() flag SQLITE_PREPARE_NO_VTAB, for preparing statements that are not allowed to use any virtual tables. Use this to prevent circular references in triggers on virtual table shadow tables from causing resource leaks. check-in: 25666e3d user: dan tags: prepare-no-vtab | |
| 18:51 | In FTS3, avoid calling memcpy() with a NULL source pointer, even if the transfer amount is zero bytes. check-in: 1abb83d2 user: drh tags: trunk | |
| 18:50 | The fts4umlaut.test module requires FTS5, so do not try to run it without that module. check-in: dee3ae90 user: drh tags: trunk | |
| 18:17 | Fix the node hash function in RTREE to ensure that it always returns a non-negative value. check-in: 0bf4c70a user: drh tags: trunk | |
| 17:51 | Fix a potential NULL-pointer deference in RTREE due to corrupt shadow tables. check-in: 1fdd3604 user: drh tags: trunk | |
| 16:53 | Prevent an infinite loop in rtree that can result from a corrupt shadow table. check-in: 08566718 user: drh tags: trunk | |
| 15:13 | Fix the RTree extension so that it correctly ignores constraints that it does not understand, even if they are against a dimension column. check-in: ed8531e5 user: drh tags: trunk | |
| 13:30 | In RTREE, turn an assert() into an if() because the condition can sometimes be false when dealing with a corrupt database. check-in: 99bce435 user: drh tags: trunk | |
| 11:53 | Remove an assert() that could fail on a corrupt db from fts3_write.c. check-in: 4cdcda40 user: dan tags: trunk | |

| 22:08 | Do not set the Cursor.seekOp test variable in the OP_NotExists opcode. This is a change to test logic only and does not affect deliverable builds. check-in: 98f34307 user: drh tags: trunk | |
| 17:32 | Fix a bug in the code that detects self-referencing rows as part of foreign key processing. Fix for [50d2a6c2]. check-in: 16fff053 user: dan tags: trunk | |
| 15:04 | Fix a segfault caused by using the RAISE function incorrectly (library now returns an error instead of crashing). check-in: ddf06db7 user: dan tags: trunk | |

| 18:11 | Fix harmless compiler warnings. check-in: 27221c69 user: drh tags: trunk | |
| 17:57 | Fix possible integer overflow while running PRAGMA integrity_check on a database file with a badly corrupted freelist. check-in: 39559911 user: drh tags: trunk | |
| 16:20 | Back out the expansion of the temporary buffer size from [32754ca6f86da816] and replace it with an explicit test for buffer overreads. check-in: 8ba3d9f3 user: drh tags: trunk | |
| 16:00 | Avoid a buffer overread in ptrmapPutOvflPtr() that can occurs in a corrupt database file that has large entries and uses autovacuum. check-in: f8b781cf user: drh tags: trunk | |
| 13:47 | Fix a harmless compiler warning in Sessions. check-in: fc9791ea user: drh tags: trunk | |
| 13:35 | Expand the size of the temporary page used during btree rebalancing by a few bytes, to avoid problems with small buffer overreads that can occur on corrupted database files. check-in: 32754ca6 user: drh tags: trunk | |
| 13:18 | When saving the position of a cursor at the b-tree layer, allocate a few extra bytes at the end of the buffer used to save the key. Otherwise, if the key is corrupt, the code that restores the cursor position may overread the buffer by a little. check-in: 160b1e31 user: dan tags: trunk | |
| 11:16 | Fix a problem with bytecode generation when a query involves two or more indexes on expressions connected by OR. Ticket [d96eba87698a428c1ddd0790ea04] check-in: 7e4ed8b5 user: drh tags: trunk | |
| 08:40 | Possible fix for [d96eba87]. Closed-Leaf check-in: 89a25abf user: dan tags: tkt-d96eba87 | |
