2018-12-22
15:50
Enhance the wal2 header comment in wal.c to explain how the wal-hook is invoked in wal2 mode. (check-in: 118aa7e3 user: dan tags: wal2)
2018-12-21
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)
2018-12-20
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)
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)
15:22
Add extra test case to wal2recover.test. (check-in: 1a5aa734 user: dan tags: wal2)
2018-12-15
20:20
Further test cases for wal2 mode. (check-in: 9cb5f8da user: dan tags: wal2)
07:12
Fix errors in comments in fts5.h. (check-in: 4002790d user: dan tags: trunk)
2018-12-14
21:58
Experimental support for new sqlite3_bind_blob() and sqlite3_bind_text() interfaces that take an extra void* argument that is passed into the destructor in front of the object that is to be destroyed. (Leaf check-in: 33a1924e user: drh tags: custom-destructors)
19:53
Add further tests for wal2 mode. (check-in: 54e628f9 user: dan tags: wal2)
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)
16:26
Add tests cases for recovery in wal2 mode. (check-in: 34f56f8a user: dan tags: wal2)
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)
20:39
Add new test file wal2big.test. (check-in: e3e50bcd user: dan tags: wal2)
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)
19:04
Add tests to ensure that each of the 4 wal read-locks does what it is supposed to. (check-in: 4d5779f3 user: dan tags: wal2)
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
17:56
Change the way wal2 locks work to ensure a reader only ever has to lock a single slot. (check-in: 18b2c23a user: dan tags: wal2)
13:44
Merge latest trunk changes into this branch. (check-in: d8dd98a3 user: dan tags: wal2)
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)
