 844 # A few subtle things about the request in this test:
 845 #
 846 #  - the server must have commit-graphs present and enabled
 847 #
 848 #  - the history is such that our want/have share a common ancestor ("base"
 849 #    here)
 850 #
 851 #  - we send only a single have, which is fewer than a normal client would
 852 #    send. This ensures that we don't parse "base" up front with
 853 #    parse_object(), but rather traverse to it as a parent while deciding if we
 854 #    can stop the "have" negotiation, and call parse_commit(). The former
 855 #    sees the actual object data and so always loads the three oid, whereas the
 856 #    latter will try to load it lazily.
 857 #
 858 #  - we must use protocol v2, because it handles the "have" negotiation before
 859 #    processing the shallow directives
