      Args:
        path_spec_object (PathSpec): path specification.
        resolver_context (Optional[Context]): resolver context, where None
            represents the built in context which is not multi process safe.
  
      Returns:
        FileEntry: file entry or None if the path specification could not be
            resolved.
