Code

protected function lazyLoadCache() {
  parent::lazyLoadCache();

  // On a cold start $this->storage will be empty and the whitelist will
  // need to be rebuilt from scratch. The whitelist is initialized from the
  // list of all valid path roots stored in the 'router.path_roots' state,
  // with values initialized to NULL. During the request, each path requested
  // that matches one of these keys will be looked up and the array value set
  // to either TRUE or FALSE. This ensures that paths which do not exist in
  // the router are not looked up, and that paths that do exist in the router
  // are only looked up once.
  if (empty($this->storage)) {
    $this
      ->loadMenuPathRoots();
