| ||
| 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) | |
|
2018-12-18
| ||
| 20:31 | In defensive mode, do not allow shadow tables to be renamed using ALTER TABLE. (check-in: 23e200da user: dan tags: trunk) | |
|
2018-12-17
| ||
| 22:19 | Move variable declaration to address compilation issue (C89). (check-in: d64f248d user: mistachkin tags: trunk) | |
|
2018-12-15
| ||
| 07:12 | Fix errors in comments in fts5.h. (check-in: 4002790d user: dan tags: trunk) | |
|
2018-12-14
| ||
| 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) | |
| 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: cc42dd15 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: 3036fd71 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: e0994e99 user: drh tags: fuzzcheck-fix) | |
|
2018-12-13
| ||
| 22:58 | Fix the dbtotxt decoder in the CLI so that it ignores excess bytes. (check-in: 18740bd4 user: drh tags: trunk) | |
| 21:52 | dbfuzz2 found a NEVER() that is sometimes true. (check-in: 1201615c 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: 997b6511 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: 682053d1 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: 1f583c53 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: 7ffa9858 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: 67a87399 user: drh tags: trunk) | |
| 15:52 | Merge the dbtotxt enhancement from trunk. (Closed-Leaf check-in: b386fce9 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: e3bf1d3e user: drh tags: trunk) | |
| 12:37 | Include OPTS in the build of dbfuzz2. (check-in: eac9c0c4 user: drh tags: trunk) | |
| 12:28 | Fix the Makefile so that it honors CFLAGS when building sessionfuzz. (check-in: 54231ac4 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: b4210d32 user: drh tags: dbfuzz2-cases) | |
|
2018-12-12
| ||
| 21:34 | Fix another problem found by Matthew Denton's new fuzzer. (check-in: 2b690dbd 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: 5c7dab85 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: 23b62fb1 user: drh tags: trunk) | |
|
2018-12-11
| ||
| 12:51 | Small performance improvement in sqlite3_step(). (check-in: d1db8d58 user: drh tags: trunk) | |
| 12:20 | Small performance improvement in the sqlite3_bind() family of interfaces. (check-in: 1dc0c3df user: drh tags: trunk) | |
|
2018-12-10
| ||
| 20:01 | Further refinements to the sqlite3_normalized_sql() interface. TH3 now gives 100% MC/DC on that interface. (check-in: c96bf6cc user: drh tags: trunk) | |
| 18:15 | Refactor the sqlite3_normalized_sql() implementation. (check-in: 06e955e5 user: drh tags: trunk) | |
| 16:49 | Fix issues with the new normalizer. (Leaf check-in: 057d7d40 user: drh tags: normalize-refactor) | |
| 16:00 | Refactor the sqlite3_normalized_sql() implementation. This is a work-in-progress. There are still issues. (check-in: a4c890b0 user: drh tags: normalize-refactor) | |
| 08:41 | Fix a problem with using "<db>-vacuum" (the default) as the state database when resuming an RBU vacuum. (check-in: c878d741 user: dan tags: trunk) | |
| 01:48 | Add support for the VACUUM INTO command. (check-in: 77f150b8 user: drh tags: trunk) | |
| 00:41 | Fix the shell1.test test for the new format of the .backup command. (Closed-Leaf check-in: 9748d799 user: drh tags: vacuum-into) | |
| 00:40 | Merge fixes from trunk. (check-in: ab1e58fa user: drh tags: vacuum-into) | |
|
2018-12-08
| ||
| 01:09 | Add the --async option to the ".backup" command in the CLI. (check-in: 7b6a605b user: drh tags: vacuum-into) | |
| 00:43 | Allow the INTO clause of VACUUM to be a text-valued expression. (check-in: af172b53 user: drh tags: vacuum-into) | |
