Code

includes/bootstrap.inc, line 1692

<?php
function drupal_generate_test_ua($prefix) {
  global $databases;

  if (!isset($key)) {
    // We use the database credentials to make the HMAC key, since we
    // check the HMAC before the database is initialized. filectime()
    // and fileinode() are not easily determined from remote.
