| 13:39 | Change the way a comparison used to detect corrupt databases in fts3 is done to avoid potential pointer overflow in 32-bit builds. Cherrypick of [95a9a39ff7]. (check-in: 27199380 user: dan tags: branch-3.22) | |
| 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) | |

| 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) | |

| 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) | |

| 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) | |

| ||
| 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) | |
| 20:28 | Add a missing OP_ColumnsUsed opcode to code for expressions like "? IN (SELECT ...)" in cases where expression can use an index that may contain NULL values. (Backported fix from version 3.14.0). (Leaf check-in: 11368e67 user: drh tags: branch-3.8.9) | |
| 20:20 | Add the OP_ColumnsUsed opcode (when compiled with SQLITE_ENABLE_COLUMN_USED_MASK) as a hint to the b-tree layer as to which columns of a btree cursor will be used. (Backport from 3.8.11) (check-in: b29e02f8 user: drh tags: branch-3.8.9) | |
| 19:53 | Add further tests for wal2 mode. (check-in: 54e628f9 user: dan tags: wal2) | |

| 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) | |

| 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) | |
