doesn't recognize it This is a 5.1 version of the patch. Problem: 'log' and 'log_slow_queries' were "fixed" variables, i.e. they showed up in SHOW VARIABLES, but could not be used in expressions like "select @@log". Also, using them in the SET statement produced an incorrect "unknown system variable" error. Solution: Since as of MySQL 5.1.12 one can enable or disable the general query log or the slow query log at runtime by changing values of general_log/slow_query_log, make 'log' and 'log_slow_queries" to be synonyms for 'general_log' and 'slow_query_log' respectively. This makes expressions using the '@@var' syntax backward compatible with 5.0 and SHOW VARIABLES output to be consistent with the SET statement.
