2018-12-31
| ||
| 21:43 | Fix harmless compiler warnings. check-in: b57c545a user: drh tags: trunk | |
| 20:39 | Additional steps to help ensure that scalar subqueries are only evaluated once even if they are used in multiple places within the query. This fixes a performance regression reported on the mailing list and caused by check-in [531eca6104e41e43] which was a fix for ticket [787fa716be3a7f650c]. Think of this check-in as an improved fix for that ticket. check-in: e1303193 user: drh tags: trunk | |
| 20:13 | Remove an optimization that can no longer occur, being superceded by the subquery-reuse optimization. Put an assert in place of the optimization to detect if the need for this optimization ever returns. Closed-Leaf check-in: 4fcdc7a2 user: drh tags: reuse-subqueries | |

| 16:36 | Fix the OP_OpenEphemeral opcode in the bytecode engine so that if it is called a second or subsequent time, it merely clears the existing table rather than creating a new one. Proposed fix for ticket [d0866b26f83e9c55e30de0821f5d]. check-in: 4678cb10 user: drh tags: trunk | |

| ||
| 14:23 | Additional small performance increase and size reduction to the sqlite3VdbeMakeLabel() mechanism. check-in: 1bdee199 user: drh tags: trunk | |
| 02:26 | A new implementation of sqlite3VdbeMakeLabel() is faster and makes fewer memory allocations by deferring memory allocation until sqlite3VdbeResolveLabel() is called, at which point the code generator has a better idea of how big the relocation table needs to be. The sqlite3VdbeMakeLabel() routine now takes a Parse* parameter instead of Vdbe*. check-in: 4a0929ac user: drh tags: trunk | |

| 02:16 | Fix a problem in which nested CTEs with the same table name trick the code generator into thinking they are the same CTE, which then tries to use the manifest them both into the same transient table. check-in: 202dd033 user: drh tags: trunk | |
| 00:30 | In the treeview debugging output, provide additional details for the Table object associated with each FROM clause term. check-in: 11d4682d user: drh tags: trunk | |

|
2018-12-25

| 11:17 | Fix a typo in a comment that is used to generate session documentation. check-in: a1f50d57 user: drh tags: trunk | |
| 00:15 | Increase the number of parameters to sqlite3WhereCodeOneLoopStart() to encourage the compiler to inline that routine within sqlite3WhereBegin(). This gives a performance improvement. check-in: 3c2ad0e9 user: drh tags: reuse-subqueries | |
|
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 | |
| 20:00 | Add a few more test cases to walfault2.test and walvfs.test. check-in: 3873941c 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 | |

| 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 | |

| 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 | |
