This series is the early stages of adding infrastructure to git to memory-effective but fast and scalable caching of object graphs. The inspiration comes from a desire to build a libfastimport and also the outstanding FIXME in hash.c Patches 1 and 2 are the first small components that have emerged from my experiments with different ways of representing and indexing graphs. Patch 3 doesn't exist at the time of composing this summary but will be an alternate hash table implementation the builds on the first two. I'm putting this out for early feedback, to be incorporated into a future complete series. -- David Barr -- 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
