A cache collector to allow for dynamic building of the locale cache.

Namespace

Drupal\locale

Code

protected function getCid() {
  if (!isset($this->cid)) {

    // Add the current user's role IDs to the cache key, this ensures that,
    // for example, strings for admin menu items and settings forms are not
    // cached for anonymous users.
    $user = \Drupal::currentUser();
    $rids = $user ? implode(':', $user
      ->getRoles()) : '';
    $this->cid = "locale:{$this->langcode}:{$this->context}:{$rids}";

    // Getting the roles from the current user might have resulted in t()
    // calls that attempted to get translations from the locale cache. In that
    // case they would not go into this method again as
    // CacheCollector::lazyLoadCache() already set the loaded flag. They would
    // however call resolveCacheMiss() and add that string to the list of
    // cache misses that need to be written into the cache. Prevent that by
    // resetting that list. All that happens in such a case are a few uncached
    // translation lookups.
