# ==== Purpose ====
#
# Test that server can work fine after moving binlog or relay log
# files to another directory and setting binlog or relay log paths to
# the new path.
# 
# ==== Method ====
#
# Start replication, and then shutdown the master, move the binary
# logs and the log index file to a another directory and then restart
# the server with option to set the new binlog directory. After master
# restarted successfully, do the similar on slave to check the relay
# log of slave.
#
# ==== Reference ====
#
# BUG#12133 master.index file keeps mysqld from starting if bin log has been moved
# BUG#42576 Relay logs in relay-log.info&localhost-relay-bin.index not processed after move
