That is, should: git replace --graft v1.5.0 v1.4.0 work? On the one hand, I see it as friendly. On the other, it may be a bit surprising when working with something as potentially dangerous a replace refs. If we don't do it automatically, the user can still say "v1.5.0^{commit}" to be explicit. I dunno; maybe I am being overly paranoid. > + /* prepare new parents */ > + for (i = 1; i < argc; i++) { > + unsigned char sha1[20]; > + if (get_sha1(argv[i], sha1) < 0) > + die(_("Not a valid object name: '%s'"), argv[i]); > + lookup_commit_or_die(sha1, argv[i]); > + strbuf_addf(&new_parents, "parent %s\n", sha1_to_hex(sha1)); > + } Either way, I think _this_ peeling is a sane thing to do. -Peff -- To unsubscribe from this list: send the line "unsubscribe git" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
