| 16:04 | Fix a problem with handling corrupt databases in the fts5 integrity-check function. (check-in: 9bad745d user: dan tags: trunk) | |
| 15:04 | Here is the beginnings of an effort to factor out the implementation of scalar subqueries to be implemented as subroutines at the end of the main body of bytecode, after the jump back to the OP_Init opcode. This is an incremental check-in that contains only preliminary changes. (check-in: 50e5f390 user: drh tags: factor-out-scalar-subselect) | |

|
2018-12-24
| ||
| 20:21 | Improvements to EXPLAIN QUERY PLAN formatting. The MULTI-INDEX OR now shows a separate "INDEX" subtree for each index. SCALAR SUBQUERY entries provide a subquery number that is related back to the .selecttrace output. (check-in: 7153552b 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

| 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) | |

| 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) | |
