# The slave is started with relay_log_space_limit=10 bytes,
# to force the deadlock after one event.

source include/master-slave.inc;
connection slave;
stop slave;

# This will generate a master's binlog > 10 bytes

# Give the I/O thread time to block.
sleep 2;
# A bug caused the I/O thread to refuse stopping.

# The I/O thread stops filling the relay log when
# it's >10b. And the SQL thread cannot purge this relay log
# as purge is done only when the SQL thread switches to another
# relay log, which does not exist here.
# So we should have a deadlock.
# if it is not resolved automatically we'll detect
# it with master_pos_wait that waits for farther than 1Ob;
# it will timeout after 10 seconds;
# also the slave will probably not cooperate to shutdown
# (as 2 threads are locked)
