Code

protected function addLanguageFallback(SelectInterface $query, $langcode) {
    // Always get the language-specific alias before the language-neutral one.
    // For example 'de' is less than 'und' so the order needs to be ASC, while
    // 'xx-lolspeak' is more than 'und' so the order needs to be DESC.
    $langcode_list = [
        $langcode,
        LanguageInterface::LANGCODE_NOT_SPECIFIED,
    ];
    if ($langcode === LanguageInterface::LANGCODE_NOT_SPECIFIED) {
        array_pop($langcode_list);
    }
    elseif ($langcode > LanguageInterface::LANGCODE_NOT_SPECIFIED) {
        $query->orderBy('base_table.langcode', 'DESC');

        $query->orderBy('base_table.langcode', 'ASC');
    }
