Regarding this hunk, since we only care about a single "did we get
any error, or did we unpack OK" bit, I think this should be more
like
if (unpack_loose_header(...) != ULHR_OK) {
error(_("unable to..."), path);
goto out;
}
It is true, as Ævar mentioned, that there is another place in the
same file that uses switch() in loose_object_info(), and it should
remain to be switch() on the returned enum because it wants to
behave differnetly depending on the kind of error it gets. But that
is not a reason to make this part that only cares about a single
"did it fail?" into a switch and force future developers to add a
useless case arm.
I left it there as posted in the previous round because I was too
lazy ;-) and also it is something we can clean up with a follow up
patch outside the series. As my today's focus has been to reduce
the number of topics waiting for a reroll, I'd rather leave things
that are not outright broken but needs clean up as they are for the
sake of expediency.
Thanks.
