18:02
Fix a problem in "PRAGMA foreign_key_check" in handling a WITHOUT ROWID child table with an INTEGER PRIMARY KEY parent key. Also, if an FK violation is detected in a WITHOUT ROWID child table, do not try to read and return the rowid.

14:16
Fix memory leaks in the code on this branch. Make use of the sqlite3_index_constraint.usage field. Do not try to handle ORDER BY terms with explicit COLLATE clauses - they don't get passed to the vtab layer anyway. check-in: 0cd75a87 user: dan tags: schemalint

Add the TK_IF_NULL_ROW opcode to deal with non-NULL result columns in the result set of a view or subquery on the RHS of a LEFT JOIN that gets flattened. Closed-Leaf check-in: 3a5860d8 user: drh tags: left-join-view
17:30
When doing a DISTINCT query using an index, try to use the index to skip ahead to the next distinct element, rather than doing a full scan of the index. (This is the "skip-ahead-distinct" optimization.) check-in: f489b5bb user: drh tags: trunk
17:18
An initial attempt to optimize VIEWs that occur as the right operand of a LEFT JOIN. This particular check-in does not work correctly because it does not deal with the case of columns in the VIEW that return non-NULL even when all columns in the table of the VIEW are NULL because of the LEFT JOIN. check-in: 1838a59c user: drh tags: left-join-view

Allow a user column name to be used on the LHS of a MATCH operator in FTS5. check-in: 6f54ffd1 user: dan tags: trunk
01:19
Forward port the skip-ahead-distinct branch which was abandoned for some reason that I do not recall. This port should have been achived by a merge of trunk into the previous head of skip-ahead-distinct, but that did not work. So I had to manually "rebase" the changes. check-in: 132339a1 user: drh tags: skip-ahead-distinct
00:12
Fix a regression caused by the fix for ticket [6c9b5514077fed34551f98e64c09a1] - control characters allowed in JSON. check-in: 8e7b6118 user: drh tags: trunk

When evaluating a query that uses an index on an expression, try to use the expression values read directly from the index rather than reevaluating the expression. check-in: a47efb7c user: drh tags: trunk

Changes to allow the code in sqlite3expert.c to be tested directly (via the API in sqlite3expert.h) instead of by invoking the sqlite3_expert application. Fix memory leaks and other problems. check-in: 5dd98317 user: dan tags: schemalint
12:31
Add a new JSON test case to verify that all control characters are escaped in the json_quote() function. check-in: 6ee12221 user: drh tags: trunk
12:25
Change the JSON extension so that it disallows control characters inside of strings. Fix for ticket [6c9b5514077fed34551f98e64c09a10dc2fc8e16]. check-in: 475d8f82 user: drh tags: trunk
