# This test proves that ER_RPL_ASYNC_EXECUTING_QUERY is thrown
# if there is an error executing queries to fetch sender
# membership details.
#
# 0. This test needs 3 servers.
# 1. Start GR on M1(primary) and create user rpl_user.
#    Also start GR on M2(secondary), and create user
#    rpl_user with revoking all its privileges, so that
#    Monitor IO/IO thread fails querying on server2.
# 2. Add asynchronous connection failover servers and
#    verify that they are inserted successfully in
#    performance_schema.replication_asynchronous_connection_failover.
# 3. Create and start new channel ch1_3: M3(replica), M1(source)
#    and verify channel ch1_3 IO and SQL THREADS are ON.
# 4. Verify 2 senders are added automatically to
#    replication_asynchronous_connection_failover table.
# 5. STOP GR on M1.
# 6. Verify error ER_RPL_ASYNC_EXECUTING_QUERY is logged in M3.
# 7. Cleanup.
