Bug #11880012: INDEX_SUBQUERY, BLACKHOLE, HANG IN PREPARING WITH 100% CPU USAGE Infinite loop in the subselect_indexsubquery_engine::exec() function caused Server hang with 100% CPU usage. The BLACKHOLE storage engine didn't update handler's table->status variable after index operations, that caused an infinite "while(!table->status)" execution. Index access methods of the BLACKHOLE engine handler have been updated to set table->status variable to STATUS_NOT_FOUND or 0 when such a method returns a HA_ERR_END_OF_FILE error or 0 respectively. 2012-03-28 10:22:31 +02:00			`#`
