mariadb/mysql-test/include/show_rpl_debug_info.inc

# ==== Purpose ====
#
# Print status information for replication, typically used to debug
# test failures.
#
# First, the following is printed on slave:
#
#   SHOW SLAVE STATUS
#   SHOW PROCESSLIST
#   SHOW BINLOG EVENTS IN <binlog_name>
#
# Where <binlog_name> is the currently active binlog.
#
# Then, the following is printed on master:
#
#   SHOW MASTER STATUS
#   SHOW PROCESSLIST
#   SHOW BINLOG EVENTS IN <sql_binlog_name>
#   SHOW BINLOG EVENTS IN <io_binlog_name>
#
# Where <sql_binlog_name> is the binlog name that the slave sql thread
# is currently reading from and <io_binlog_name> is the binlog that
# the slave IO thread is currently reading from.
#
# ==== Usage ====
#
# [let $master_connection= <connection>;]
# source include/show_rpl_debug_info.inc;
#
# If $master_connection is set, debug info will be retrieved from the
# connection named $master_connection.  Otherwise, it will be
# retrieved from the 'master' connection if the current connection is
# 'slave'.
