# BUG#12400313 / BUG#64503 test case
#
#
# Description
# -----------
#  
# This test case starts the slave server with: 
# --relay-log-space-limit=8192 --relay-log-purge --max-relay-log-size=4096
# 
# Then it issues some queries that will cause the slave to reach
# relay-log-space-limit. We lock the table so that the SQL thread is
# not able to purge the log and then we issue some more statements.
#
# The purpose is to show that the IO thread will honor the limits
# while the SQL thread is not able to purge the relay logs, which did
# not happen before this patch. 
# It is proved that when the blocking
# condition are removed the occupied relay log space shrinks back to
# below the limit.
