The has_pack_index() function has several oddities that may make it surprising if you are trying to find out if we have a pack with some $hash: - it is not looking for a valid pack that we found while searching object directories. It just looks for any pack-$hash.idx file in the pack directory. - it only looks in the local directory, not any alternates - it takes a bare "unsigned char" hash, which we try to avoid these days The only caller it has is in the dumb http code; it wants to know if we already have the pack idx in question. This can happen if we downloaded the pack (and generated its index) during a previous fetch. Before the previous patch ("dumb-http: store downloaded pack idx as tempfile"), it could also happen if we downloaded the .idx from the remote but didn't get the matching .pack. But since that patch, we don't hold on to those .idx files. So there's no need to look for the .idx file in the filesystem; we can just scan through the packed_git list to see if we have it. That lets us simplify the dumb http code a bit, as we know that if we have the .idx we have the matching .pack already. And it lets us get rid of this odd function that is unlikely to be needed again.
