Vicențiu Ciorbaru	1c858dd9e0	Make win_big test specify only if Sort_merge_passes have happened ... The number is irrelevant and may differ by architecture. We are only interested if it happened or not	2016-09-24 15:12:34 +02:00
Sergei Petrunia	047963922c	MDEV-9736: Window functions: multiple cursors to read filesort result ... Add support for having multiple IO_CACHEs with type=READ_CACHE to share the file they are reading from. Each IO_CACHE keeps its own in-memory buffer. When doing a read or seek operation on the file, it notifies other IO_CACHEs that the file position has been changed. Make Rowid_seq_cursor use cloned IO_CACHE when reading filesort result.	2016-09-24 15:12:34 +02:00
