So, the proposal is to create an index of young objects without doing reachability analysis (I still didn't get the point of packing them; as I pointed out, it seems to be rather counter-productive) to help the actual packing? From what I vaguely understood: 1. Index all the young objects to save a history traversal (?) 2. Perform the reachability analysis using the index in step 1, and then generate the pack. I'm not yet clear about what information 1 contains to help 2. Is it the rough ordering? (The big important objects come near the top of the pack, and the deltas are generated against them). I say "rough" because the ordering might change after the unreachable objects are pruned. *scratches head* -- To unsubscribe from this list: send the line "unsubscribe git" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
