# Bug#17879675:SHUTDOWN HANG IF SEMISYNC IS ENABLED AND SLAVE ABORT
#
# Problem:
# ========
# Step 1. enable semisync and set a big value for
# rpl_semi_sync_master_timeout.
#
# Step 2. kill io thread of slave, so the threads on master will keep on
# WAITING ACK FROM SLAVE.
#
# Step 3.shutdown the master ---hang
#
# Test:
# =====
# Stop IO thread and execute a transaction on master. The transaction thread
# will wait for an ack as IO thread is stopped.  Now shutdown the master the
# shutdown should not hang.  Shutdown should stop the dump thread and the
# dump thread should wakeup the waiting transaction thread and switch off
# semisync as there are no active slaves connected to the server.
