Revision 1389d9ddaa68a4cbf5018d88f971b9bbb7aaa3c9 authored by Junio C Hamano on 06 January 2007, 10:16:19 UTC, committed by Junio C Hamano on 07 January 2007, 06:57:34 UTC
The logic in an earlier round to detect reflog entries that point at a broken commit was not sufficient. Just like we do not trust presense of a commit during pack transfer (we trust only our refs), we should not trust a commit's presense, even if the tree of that commit is complete. A repository that had reflog enabled on some of the refs that was rewound and then run git-repack or git-prune from older versions of git can have reflog entries that point at a commit that still exist but lack commits (or trees and blobs needed for that commit) between it and some commit that is reachable from one of the refs. This revamps the logic -- the definition of "broken commit" becomes: a commit that is not reachable from any of the refs and there is a missing object among the commit, tree, or blob objects reachable from it that is not reachable from any of the refs. Entries in the reflog that refer to such a commit are expired. Since this computation involves traversing all the reachable objects, i.e. it has the same cost as 'git prune', it is enabled only when a new option --fix-stale. Fortunately, once this is run, we should not have to ever worry about missing objects, because the current prune and pack-objects know about reflogs and protect objects referred by them. Unfortunately, this will be absolutely necessary to help people migrate to the newer prune and repack. Signed-off-by: Junio C Hamano <junkio@cox.net>
