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
2018-12-22
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
15:50
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
15:46
Remove unnecessary whitespace from testcase result strings. check-in: ad70f03c user: drh tags: trunk

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
2018-12-21
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
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

2018-12-14
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

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

03:16
Report corruption when an attempt is made to write a pointer-map page that is also being used as a btree page.

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

dbfuzz2 found a NEVER() that is sometimes true. check-in: 1201615c 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
