The fixed size helps peers uniquely identify any pieces by splitting the whole transfer equally and indexing them in 1-dimension. It's a rule to help identify pieces, not the only valid rule. In git, given a commit SHA-1 we can identify any parts (or "pieces") that are reachable from that commit using rev-list syntax. Therefore the "identifiable" characteristics still holds even we don't split in fixed size pieces. -- Duy -- 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
