11:39
The SQLITE_EXTRA_IFNULLROW compile-time option causes OP_IfNullRow opcodes to be issued for references to the right-hand side table of *any* flattened join, not just LEFT JOINs. This puts extra stress on the OP_IfNUllRow opcodes for testing purposes. check-in: 1a074c8a user: drh tags: branch-3.19
00:28
The TK_IF_NULL_ROW expression node must be treated as a variable that references the table Expr.iTable. Proposed fix for ticket [7fde638e94287d2c]. check-in: b30a364a user: drh tags: branch-3.19

08:04
Fix a case where NULL was being passed to memcmp() following an OOM. This is probably not a real problem, as the number-of-bytes parameter was passed 0 in this case, but it was causing a santizer complaint. check-in: 3ea2bad2 user: dan tags: trunk

Consolidate two branches of code in the "PRAGMA foreign_key_check" implementation. check-in: 69f51f83 user: dan tags: trunk
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. The second column returned by "PRAGMA foreign_key_check" in this case (WITHOUT ROWID child table) is now always set to NULL. check-in: 690870bd user: dan tags: trunk

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

Only use the skip-ahead-distinct optimization if the index has been analyzed and we know that a skip-head is likely to skip over at least 11 rows. The magic number 11 was determined by experimentation. check-in: 0cf16dec user: drh tags: skip-ahead-distinct

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
