- Added query_cache_type == ALWAYS_OFF to turn of query cache permanently for new open tables. Without this option storage engines has to call query cache for all update querys and invalidate used tables that has a small overhead. When running benchmarks without query cache, this is the option to use! - Updated MyISAM, Aria, MYISAM_MRG and InnoDB to support ALWAYS_OFF. - Setting query_cache_size in a config file will not automatically enable the query cache. - Added query_cache_available() that functions can check if query cache can be used or if it is permanently disabled. - Moved things around in Query_cache::store_query() to get more work done outside of query cache mutex. - Same for Query_cache::send_result_to_client() Co-author: Thirunarayanan Balathandayuthapani <thiru@mariadb.com> - ÌnnoDB changes reviewed and improved
