# If the action thread is killed but the distributed execution
# has already gone beyond a point where all servers agreed (cannot be
# canceled) then the action will complete.
#
# Test:
# 0. This test requires two servers
# 1. Use the debug point "group_replication_block_group_action_stop" on server 1
# 2. Start a change to single primary mode on server 1
# 3. Wait for the stage to be: Primary Switch: waiting for operation to
# complete on all members
# 4. Kill the query
# 5. Unblock the debug point with "signal.action_stop_continue"
# 6. Check the action returns successfully.
# 7. Cleanup
