At > least as far as I can tell... Yes, we used to run into problems with failed pushes sometimes at GitHub. A later `git gc` will clean up the tmp_* objects (via `git prune`), but of course we will not run the prune if the repack fails. Also note that a push will just keep receiving objects as long as the client wishes to send them, spooling straight to disk, before any enforcement hooks have a chance to run. So on stock git, you could in theory just fill up the receiver's disk, and then git will leave the file sitting around. I have a patch to make index-pack just do a hard hangup after receiving `receive.maximumBytes` bytes (with an appropriate message to stderr). It's not an exact measure of the size of the push (since we need to complete thin packs, and we may also explode smaller packs), but it at least bounds the size that the sender can push. I'm happy to share the patch if others are interested (it's only a few lines). I've also considered a patch to have index-pack clean up tmp_pack_* automatically on exit, default to off (i.e., the current behavior). A busy site could turn it on globally, and then shut it off for a specific repo when trying to debug a push problem. I find that the leftover tmp_pack files are very seldom of interest for forensic debugging. I haven't bothered to write that patch, though; we dropped our prune expiration time well below the 2-week default, so the tmp files get cleaned up pretty regularly now. -Peff -- 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
