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.
