Use git revisions. Those aren't bzr revisions, they're marks from a git stream dump. If they're messed up, then the parent links in the live git repo are messed up too. I ran some auditing code on the first 1100 or so commits. This is what came out: wrong parent links under :417 wrong parent links under :503 wrong parent links under :512 wrong parent links under :520 wrong parent links under :528 wrong parent links under :613 wrong parent links under :620 wrong parent links under :624 wrong parent links under :626 wrong parent links under :629 wrong parent links under :637 wrong parent links under :641 wrong parent links under :646 wrong parent links under :651 wrong parent links under :655 wrong parent links under :862 wrong parent links under :894 wrong parent links under :926 wrong parent links under :934 wrong parent links under :939 wrong parent links under :947 wrong parent links under :966 wrong parent links under :975 wrong parent links under :1011 multiple root commits: set(['commit@:676', 'commit@:1017', 'commit@:75', 'commit@:579', 'commit@:39', 'commit@:2']) Bottom line is, the topology is badly screwed up. I already knew about the multiple root commits; I'm fairly sure they relate to these junk branches 21 commit refs/tags/lost+found/d4cd8d7c34cc79dc4abd0fec33cec74afa33e2d0 1723 commit refs/tags/lost+found/12d398afa4d2b77d606b28fe43a2e5200c863419 3595 commit refs/tags/lost+found/e387e14faeea08877c99ddf798d5a4c9f7999c72 3763 commit refs/tags/lost+found/9a1501510c2a842e8597d695fec05563161a84b7 3773 commit refs/tags/lost+found/5cf718038f760d6dc2e21dee3ce98061a975488a which I was going to delete anyway. They seem to consist entirely of dummy test commits by Glen Morris. -- Eric S. Raymond
