I should be able to finish it up tomorrow. :-) I don't know if I've made this more complex than I really need to but I've permitted multiple windows per pack. There is just one LRU of all windows across all packs and a maximum amount of address space to use for pack mappings. Least recently used window gets tossed when we need a different window. This permits us to keep say a window active on the front of a pack (near the commits) and another different active window closer to the back (near the blobs). That multiple window feature made it a slightly non-trivial copy and paste from fast-import but I think its worth it for tree walking type applications. -- Shawn. - 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
