I wrote the below code

    from git import Git, Remote
    assert isinstance(working_tree_ref, string_types), 'Decorator    requires    ref    name    for    working    tree    checkout'
    def argument_passer(func):
        @wraps(func)
        def remote_repo_creator(self):
            rw_daemon_repo_dir = tempfile.mktemp(prefix=('daemon_repo-%s-' % func.__name__))
            rw_repo_dir = tempfile.mktemp(prefix=('daemon_cloned_repo-%s-' % func.__name__))
            rw_daemon_repo = self.rorepo.clone(rw_daemon_repo_dir, shared=True, bare=True)
            rw_repo = rw_daemon_repo.clone(rw_repo_dir, shared=True, bare=False, n=True)
            try:
                rw_repo.head.commit = working_tree_ref
                rw_repo.head.reference.checkout()
                rw_daemon_repo.daemon_export = True
                with rw_daemon_repo.config_writer() as crw:
                    section = 'daemon'
                    try:
                        crw.add_section(section)
                    except Exception:
                        pass
                    crw.set(section, 'receivepack', True)
                d_remote = Remote.create(rw_repo, 'daemon_origin', rw_daemon_repo_dir)
                d_remote.fetch()
                (base_daemon_path, rel_repo_dir) = osp.split(rw_daemon_repo_dir)

                with git_daemon_launched(Git.polish_url(base_daemon_path, is_cygwin=False), '127.0.0.1', GIT_DAEMON_PORT):
                    rw_repo.git.ls_remote(d_remote)
                    with cwd(rw_repo.working_dir):
