In fact different branches will store different deltas depending on how their DAGs get topologically sorted. The object I care about is the original text, so that's the hash I store. > In other words, you need to hash the metadata too. Otherwise how do you > consistency-check the _collection_ of files? Well naturally, I hash the metadata too. For every change, there's a toplevel changeset hash that is the hash of the entire project state at that time. And it's all signable and so on. Just like git and just like Monotone. -- Mathematics is the supreme nostalgia of our time. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/ | ||||||||||
