function assertDirectoryPermissions($directory, $expected_mode, $message = NULL) {

  // Configuration system stores default modes as strings.
  if (is_string($expected_mode)) {

    // Convert string to octal.
    $expected_mode = octdec($expected_mode);

  // Clear out PHP's file stat cache to be sure we see the current value.
  clearstatcache(TRUE, $directory);

  // Mask out all but the last three octets.

  // PHP on Windows has limited support for file permissions. Usually each of
  // "user", "group" and "other" use one octal digit (3 bits) to represent the
  // read/write/execute bits. On Windows, chmod() ignores the "group" and
  // "other" bits, and fileperms() returns the "user" bits in all three
  // positions. $expected_mode is updated to reflect this.
  if (substr(PHP_OS, 0, 3) == 'WIN') {

    // Reset the "group" and "other" bits.
    $expected_mode = $expected_mode & 0700;

    // Shift the "user" bits to the "group" and "other" positions also.
    $expected_mode = $expected_mode | $expected_mode >> 3 | $expected_mode >> 6;
