Vicențiu Ciorbaru	be2b833c42	It is now possible to remove values multiple times from window functions ... This can happen with degenerate frame definitions that are always empty.	2016-09-09 18:53:01 +03:00
Vicențiu Ciorbaru	1adc3fab23	MDEV-10097: Assertion `count > 0' failed in Item_sum_sum::add_helper(bool) ... When specifying a RANGE type frame that exceeds the partition size, both for the top and bottom cursors we end up removing more rows than added to the aggregate function. This happens because our TOP range cursor, which removes values from the aggregate function, would be allowed to breach partition boundaries, while the BOTTOM range cursor would not. To prevent this from happening, force the TOP range cursor to only move within the current partition, as does the BOTTOM range cursor.	2016-09-09 18:32:35 +03:00
