Hi, Here's something I noticed back in 2012 or so, and stumbled upon again recently. Start eg at the root of git's own repository: $ cd xdiff/ $ git archive --format=tar HEAD .. | tar t fatal: ..: '..' is outside repository at '/Users/matthias/prog/git' In the best case, I would have hoped to get an archive of the whole repository here. At a minimum, I would hope for an error message that was less confusing: the directory I was referring to is very much inside the repository. For comparison, `git -C .. archive --format=tar HEAD | tar t` has the behaviour that I would expect in this scenario: a tarball of the whole repository. (I don't know enough about git to produce a patch to fix this at this point, but I can try looking into fixing this.) Thanks, Matthias.
