Module conversion to 5.x

Is this module maintaned?
I think file transfer resume thru private metod is a must have.

A little bug is that anonimous users can download. I've achieved to workaroun this doing the following in filerequest.module _filerequest_download() function:

Add $filepath = implode('/', $args); affter $args = func_get_args(); without removing $config["filename"] = implode('/', $args);
Comment foreach line and the }
Change $headers = module_invoke_all($module, 'file_download', $_GET['file']); to $headers = module_invoke_all('file_download', $filepath);

Final function code looks as follows:

/**
 * Process the download request. If it's a file leecher redirect it to the
 * associated node, otherwise return an access_denied error.
 */
function _filerequest_download() {
  define("__DRUPAL_BASE_DIR", dirname(dirname(dirname(__FILE__))).DIRECTORY_SEPARATOR);
  require_once("downloadhandler.php");

  $args = func_get_args();
  //BY NITEMAN
  $filepath = implode('/', $args);
  // END BY NITEMAN
  $config["filename"] = implode('/', $args);
  $config["filereq_antileech_enabled"] = variable_get('filereq_antileech_enabled', true);
  $config["filereq_antileech_regex"] = variable_get('filereq_antileech_regex', preg_quote($_SERVER["HTTP_HOST"]));
  $config["filereq_antileech_image_mode"] = variable_get('filereq_antileech_image_mode', 0);
  $config["filereq_antileech_image_file"] = variable_get('filereq_antileech_image_file', "modules/filerequest/watermark.png");

  if (!__fr_can_download_file($config)) define("__FILEREQ_LEECH", $file);

  if (defined("__FILEREQ_LEECH"))
  {
    global $__fr_reporting_leech;
    if ($__fr_reporting_leech) __fr_delayed_report();
    $result = db_result(db_query("SELECT nid FROM {files} WHERE filepath = '%s'", $config["filename"]));
    if ($result !== false)
    {
      drupal_goto("node/".$result);
      exit;
    }
    drupal_access_denied();
    return;
  }
  $config["filename"] = file_create_path($config["filename"]);
  if (file_exists($config["filename"])) {
    $list = module_list();
    // BY NITEMAN foreach ($list as $module) {
      // BY NITEMAN $headers = module_invoke_all($module, 'file_download', $_GET['file']);
      $headers = module_invoke_all('file_download', $filepath);
      if (in_array(-1, $headers)) {
        return drupal_access_denied();
      }
      else if (count($headers)) {
        // set custom headers
        $forceMime = '';
        foreach ($headers as $header) {
          header($header);
          if (preg_match('#^Content-Type: (.*)$#i', $header, $match)) {
            $forceMime = $match[1];
          }
        }
        // make sure no caching headers are set
        header("Cache-Control:");
        header("Pragma:");
        header("Expires:");
        // unset other headers we (might) set
        header("Content-Range:");
        header("Content-Length:");
        header("Content-Type:");
        header("Last-Modified:");
        header("Content-Disposition:");
        __fr_process_download($config["filename"], preg_match("#(\?|&)download(&|$)#", $_SERVER["REQUEST_URI"]), $config["watermark"], $forceMime);
        exit();
      }
    // BY NITEMAN}
  }
  drupal_not_found();
}

Every change is marked with NITEMAN word ;)

This should be fixed in Drupal core. We could use a review of issue 91934 to help get file transfer resume support for private downloads in core.
