#
# This test validates transactions monitor dies if client disconnects post
# executing UDF or when UDF errors out.
# KILL query is blocked so testing of KILL connection cannot be done.
#
# Test:
# 0. This test requires two servers
# 1. Start group in single primary mode.
# Server1 will be primary and server 2 secondary.
# 2. Add a debug point to block the primary change on validation.
# 3. Start a primary change on server 1 using connection client_disconnect
# 4. Wait for the THD_transaction_monitor thread to start.
# 5. Disconnect the client_disconnect connection.
# And signal the operation to run.
# 6. Check the monitor thread exited.
# 7. Cleanup
