Functions that need to be loaded on every Backdrop request.

Code

  // running tests. However, for security reasons, it is imperative that we
  // validate we ourselves made the request.
  if ($test_prefix = backdrop_valid_test_ua()) {
    // Set the test run id for use in other parts of Backdrop.
    $test_info = &$GLOBALS['backdrop_test_info'];
    $test_info['test_run_id'] = $test_prefix;
    $test_info['in_child_site'] = TRUE;

      // Extract the current default database prefix.
