I recently figured out a way to alter the transport API slightly to make it possible to attach foreign VCSes there. This amounts to allowing get_refs_list() to leave the sha1s null, and allowing fetch() to set them. This just requires a copy of a ref list in the clone path, and a check to make null (for not having a ref) not match null (for not knowing the hash of the ref) in the fetch logic. I think I will end up changing the spec, mostly to allow a single non-trivial call to the helper to provide both the list of refs and the fast-import stream; this matches how the pack protocol works (except, of course, that the initial list doesn't have hashes, and the output goes to fast-import instead of unpack-objects). I'm going to rebase the series at some point, but I've been focused more on the more core transport and remote stuff now that I think I can go through that. -Daniel *This .sig left intentionally blank* -- 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
