Merge Revision revid:svn-v4:16c675df-0fcb-4bc9-8058-dcc011a37293:branches/zip:6674 from MySQL InnoDB
Original revid:svn-v4:16c675df-0fcb-4bc9-8058-dcc011a37293:branches/zip:6674
Original Authors: inaam
Original commit message:
branches/zip bug# 49535
This is a backport of r4924.
mem_heap_get_size() scans all allocated blocks to calculate the total
size of the heap. This patch introduces a new, total_size, field in
mem_block_info_struct. This field is valid only for base block
(i.e.: the first block allocated for the heap) and is set to
ULINT_UNDEFINED in other blocks.
This considerably improves the performance of redo scan during recovery.
