Code

protected function getCid() {

    // for example, strings for admin menu items and settings forms are not
    // cached for anonymous users.

    // 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.
