- Updated slow_query_log_file_basic and general_log_file basis instead of the func version as the func version run good but the basic versions fail. - Sent innodb.test to dev@innodb.com. - variables.test has differences probably due to a bug in mtr or in the SET statement (see bug#39369). - general_log_file_basic.test and slow_query_log_file_bsaic.test have differences, which might be produced by the new mtr (see bug#38124).
