Some basics to implement before we could really have network protocols: For client-side fetch, and server-side receive, we'll need: * Reachability walking * Creating indexes (.idx, .rev) from packs (streaming API) * A streaming hash verifier for the pack ingestion path. * Other things involving pack ingestion, such as reading and validating the pack header, un-thinning thin objects, streaming byte to a quarantined .pack while hashing the trailer, checking the trailer near the end. For client-side send, and server-side upload, we'll need: * Reachability walk (always iterators or otherwise streaming; haves/wants; never an entire slice/map of OIDs) * Delta compression based on FastCDC; see 9front git * Using bitmaps * Investigate in detail the architecture of creating thin packs
