FLUSH LOGS now rotates relay logs, and a new variable max_relay_log_size. Plus a very small bit of code cleaning. libmysqld/lib_sql.cc: open_log has no default arguments anymore. mysql-test/r/rpl_flush_log_loop.result: result update now that FLUSH LOGS rotates relay logs. mysql-test/r/rpl_log.result: result update now that FLUSH LOGS rotates relay logs. mysql-test/r/rpl_rotate_logs.result: result update now that max_binlog_size is 4096. mysql-test/t/rpl_rotate_logs-master.opt: now max_binlog_size must be a multiple of 4096 (see change in mysqld.cc) sql/log.cc: Got rid of default arguments of various MYSQL_LOG methods (the default arguments made code reading uneasy). Set max_size in ::init(). New function set_max_size() to set max_size of a MYSQL_LOG on-the-fly. More DBUG info. sql/mysql_priv.h: no defaults in open_log(). New variables max_relay_log_size. sql/mysqld.cc: New variable and option max_relay_log_size. max_binlog_size and max_relay_log_size are multiples of IO_SIZE. No more default arguments for log functions. sql/set_var.cc: New variable max_relay_log_size. If it is 0, then max_binlog_size will apply to relay logs. When one of these variables is changed, fix_max_%log_size is called to update max_size of the binary and/or relay logs. sql/slave.cc: New function rotate_relay_log(). sql/slave.h: New function rotate_relay_log(). sql/sql_class.h: New member max_size of MYSQL_LOG (for automatic rotation). New method set_max_size() for setting on-the-fly. sql/sql_parse.cc: Flush the relay log in FLUSH LOGS.
