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