If you drop down to the \"git pack-objects\" level, you can\n manually convince it to do so.\n\n I have a patch to add \"git repack -k\", which packs even unreachable\n objects (we use this at GitHub, since our routine repository\n maintenance never deletes objects). If people are interested, I can\n clean it up and post it to the list.\n\n - why your repo grew during the gc; packed unreachable objects are\n exploded into loose objects during a gc, so they can age and expire\n on their own (we use filesystem mtimes to determine how old they\n are).\n\n Git is smart enough not to explode loose objects that it is just\n going to prune in a moment. But the default expiration time is 2\n weeks, so there's a good chance it would want to keep some of them.\n\n If you use \"git gc --prune=now\", that should prune everything\n immediately (and this is safe, as long as you know there are no\n simultaneous users of your local repository).\n\n-Peff\n"}]}
