Insufficient testing on my part; patch at the end. > With git-ssh-pull, the situation is even more vexing - it refuses to > fetch the packs for some reason yet unknown to me (I will debug it > tomorrow). git-ssh-pull doesn't deal in packs; it gets individual objects out of packs, which git-ssh-push (on the remote side) should be extracting. Perhaps you have a git-ssh-push on the remote side that's before I make packs work (it used to need to have the files for objects it was sending). At some point, I have to revisit getting git-ssh-* to generate exactly the required pack and transfer that, but that's an efficiency issue, not a correctness one, and shouldn't be relevant to the problem you're having. --- [PATCH] Also parse objects we already have In the case where we don't know from context what type an object is, but we don't have to fetch it, we need to parse it to determine the type before processing it.
