| 07:16 | Fix cut-and-paste error in test file fts4umlaut.test. (check-in: cad5da1bf5 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: db8d1d12f5 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: a3fdb2c78d 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: 48438bb35b user: drh tags: trunk) | |
| 22:08 | Improved detection of shadow table corruption in RTREE. (check-in: b39bf4356e 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: da587d1857 user: dan tags: trunk) | |
| 19:55 | Use SQLITE_PREPARE_NO_VTAB in rtree as well. (Closed-Leaf check-in: 82a2ae7132 user: dan tags: prepare-no-vtab) | |
| 19:30 | Add tests for the use of SQLITE_PREPARE_NO_VTAB in fts5. (check-in: 1999612010 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: 25666e3d03 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: 1abb83d29a user: drh tags: trunk) | |
| 18:50 | The fts4umlaut.test module requires FTS5, so do not try to run it without that module. (check-in: dee3ae9001 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: 0bf4c70a68 user: drh tags: trunk) | |
| 17:51 | Fix a potential NULL-pointer deference in RTREE due to corrupt shadow tables. (check-in: 1fdd3604ee user: drh tags: trunk) | |
| 16:53 | Prevent an infinite loop in rtree that can result from a corrupt shadow table. (check-in: 085667180b 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: ed8531e575 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: 99bce4358b user: drh tags: trunk) | |
| 11:53 | Remove an assert() that could fail on a corrupt db from fts3_write.c. (check-in: 4cdcda408a 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: 98f3430778 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: 16fff05347 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: ddf06db702 user: dan tags: trunk) | |
|
2018-12-18
| ||
| 20:31 | In defensive mode, do not allow shadow tables to be renamed using ALTER TABLE. (check-in: 23e200da5c user: dan tags: trunk) | |
|
2018-12-17
| ||
| 22:19 | Move variable declaration to address compilation issue (C89). (check-in: d64f248da3 user: mistachkin tags: trunk) | |
|
2018-12-15
| ||
| 07:12 | Fix errors in comments in fts5.h. (check-in: 4002790d94 user: dan tags: trunk) | |
|

| ||
| 18:11 | Fix harmless compiler warnings. (check-in: 27221c6990 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: 395599116d 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: 8ba3d9f380 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: f8b781cf41 user: drh tags: trunk) | |
| 13:47 | Fix a harmless compiler warning in Sessions. (check-in: fc9791ea98 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: 32754ca6f8 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: 160b1e31c0 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: 7e4ed8b5c2 user: drh tags: trunk) | |
| 08:40 | Possible fix for [d96eba87]. (Closed-Leaf check-in: 89a25abfcd user: dan tags: tkt-d96eba87) | |
| 03:16 | Report corruption when an attempt is made to write a pointer-map page that is also being used as a btree page. Also, fix a bug in fuzzcheck that cause it to overlook a pointer-map bug that was trigger by the fuzzcheck test data, and also fix the pointer-map bug. (check-in: cc42dd1510 user: drh tags: trunk) | |
| 03:14 | Detect when an attempt is made to write to a pointer map page that is also being used as a btree page and report corruption. (Closed-Leaf check-in: 3036fd71ac user: drh tags: fuzzcheck-fix) | |
| 02:29 | Fix a bug in the custom in-memory VFS used by fuzzcheck. This bug masks other bugs that should have caused some existing fuzzdata7.db entries to fail, and so this fix is initially on a branch until those other bugs can be repaired. (check-in: e0994e9995 user: drh tags: fuzzcheck-fix) | |

| 22:58 | Fix the dbtotxt decoder in the CLI so that it ignores excess bytes. (check-in: 18740bd448 user: drh tags: trunk) | |
| 21:52 | dbfuzz2 found a NEVER() that is sometimes true. (check-in: 1201615cbb user: drh tags: trunk) | |
| 21:11 | Add extra tests for database corruption inside the defragmentPage() routine, as dbfuzz2 has found ways for corruption to leak into that point. Add test cases in fuzzdata7.db. (check-in: 997b65117f user: drh tags: trunk) | |
| 21:05 | Fix a problem in sqlite3BtreeDelete() in which deleting an entry from a corrupt database can leave a btree page with zero cells. (check-in: 682053d1e6 user: drh tags: trunk) | |
| 20:49 | Add the "decode_hexdb" TCL command to testfixture. Add the dbfuzz001.test module to demonstration how to use decode_hexdb to deserialize a dbtotxt database description for use in a corruption test. (check-in: 1f583c53f3 user: drh tags: trunk) | |
| 18:59 | Fix the CLI to keep proper track of input line numbers for use in error messages, even after processing in-line hex database inputs using ".open --hexdb". (check-in: 7ffa985816 user: drh tags: trunk) | |
| 18:30 | Fix the CLI so that the ".open --hexdb" command works even if it is contained in a subscript that is read using ".read". (check-in: 67a87399b8 user: drh tags: trunk) | |
| 15:52 | Merge the dbtotxt enhancement from trunk. (Closed-Leaf check-in: b386fce9a2 user: drh tags: dbfuzz2-cases) | |
| 15:06 | Add the "dbtotxt" utility program and the ability to read "dbtotxt" output as a deserialized input database in the CLI, using the --hexdb option to the ".open" command. (check-in: e3bf1d3ea5 user: drh tags: trunk) | |
| 12:37 | Include OPTS in the build of dbfuzz2. (check-in: eac9c0c496 user: drh tags: trunk) | |
| 12:28 | Fix the Makefile so that it honors CFLAGS when building sessionfuzz. (check-in: 54231ac4ca user: drh tags: trunk) | |
| 03:36 | New database corruption test cases discovered by dbfuzz2. The new cases have been added to test/fuzzdata7.db, but have not yet all been fixed, so tests will not currently pass. (check-in: b4210d320c user: drh tags: dbfuzz2-cases) | |

| 21:34 | Fix another problem found by Matthew Denton's new fuzzer. (check-in: 2b690dbdff user: drh tags: trunk) | |
| 20:11 | Remove an ALWAYS() from a branch that is not always taken. The test case found by OSSFuzz has been added to TH3. (check-in: 5c7dab8553 user: drh tags: trunk) | |
| 11:23 | OSSFuzz found a case where an assert() inside sqlite3ExprCompare() can be true. Test case added to TH3. (check-in: 23b62fb160 user: drh tags: trunk) | |
