With a bit of luck, the reflog actually contain useful information. Look at .git/logs/HEAD (or refs/heads/* instead of HEAD for branches' reflog). It's a human-readable text format. You should be able to walk up the history looking for a good commit. > I do a hack that Before anything else: do a backup of your full repository while it's still time. > i change the HEAD commit to the one that i can make sure is right, (don't forget to run "git fsck" to make sure that not only the commit but also its ancestry is right). > In fact, i hope git fsck can fix up such problems(maybe can backup top > commit for example)... Not as far as I know. But "git fsck" has a --lost-found option that can help recovering unreachable (dangling) commits. You may have a look at http://hackage.haskell.org/package/git-repair but I do not think it would solve your particular case. -- Matthieu Moy http://www-verimag.imag.fr/~moy/ -- 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
