Modify qpush/qpop idempotent operations to return success Modify qpush/qpop such that idempotent instances of the operations return success. That is, repeated qpush -a, qpop -a, qpush patch-name or qpop patch-name will return success. The end goal of each of these operations is to reach a particular state. Whether or not the patches were already applied does not affect that state or operation status. Likewise, be careful to retain the error status on a qpush/qpop without arguments when the end/beginning of the series has been reached.
