Applying InnoDB snapshot, fixes BUG#49535.
Detailed revision comments: r6674 | inaam | 2010-02-11 17:54:44 +0200 (Thu, 11 Feb 2010) | 16 lines 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. rb://108 issue#216 Approved by: Heikki
