I would have thought "git repack -adl" works, but I think there is something a little funny in the logic. It reports "nothing new to pack", but does not delete the loose objects. But packing first then worked: $ git clone large-parent child $ echo $PWD/large-parent/.git/objects >child/.git/objects/info/alternates $ cd child $ du -sh .git/objects 51M .git/objects $ git repack -adl && du -sh .git/objects Nothing new to pack. 51M .git/objects $ git repack -ad && du -sh .git/objects Counting objects: 3, done. Delta compression using up to 2 threads. Compressing objects: 100% (2/2), done. Writing objects: 100% (3/3), done. Total 3 (delta 0), reused 0 (delta 0) 51M .git/objects $ git repack -adl && du -sh .git/objects Nothing new to pack. 20K .git/objects -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
