Just to set my expectation straight. Do you expect/wish this not to
fail because of this in cmd_rev_parse()?
/* No options; just report on whether we're in a git repo or not. */
if (argc == 1) {
setup_git_directory();
git_config(git_default_config, NULL);
return 0;
}
Because we do not have anything other than yes/no to the question
"Are we in Git repository?", I'd expect that the expected answer to
the question would be "no" (if we could say "Yes, we are in a Git
repository but its version and layout is unknown to us so we are not
supposed to look at or touch it", that is a different matter).
So "fatal:" may be bad, but I think not seeing "ok" is what we
want to happen in this case.
Having said that, I am not sure asking for default-config is what we
wanted to do in the above code. Perhaps a more modern way to write
the above code would be to do the "gently" version of setup, without
calling git_config() ourselves, and return the resulting value
returned in *nongit_ok? If we can do so without triggering "fatal:"
and still return "no, we are not in a Git repository we are supposed
to touch", that would be good.
Or are you discussing a more general issue, iow, anything that can
work without repository (i.e. those who do _gently version of the
setup and act on *nongit_ok) should pretend as if there were no
(broken) repository and take the "no we are not in a repository"
codepath?
