Feature #13568 » 0001-File-path-Raise-IOError-when-a-file-is-O_TMPFILE.patch

      *  not normalize the name.
+     *
      *  The pathname may not point the file corresponding to <i>file</i>.
      *  e.g. file has been moved, deleted, or created with <code>File::TMPFILE</code> option.
      *  For instance, pathname becomes inaccurate when file has been moved or deleted.
+     *
      *  This method raises <code>IOError</code> for a <i>file</i> created using
      *  <code>File::Constants::TMPFILE</code> because they don't have a pathname.
+     *
      *     File.new("testfile").path               #=> "testfile"
      *     File.new("/tmp/../tmp/xxx", "w").path   #=> "/tmp/../tmp/xxx"
