Code

protected function storeSetupCache($cache_key_prefix = '') {
  $cache_key = $this
    ->getSetupCacheKey($cache_key_prefix);
  $lock_key = 'simpletest_store_cache_' . $cache_key . '_' . $this->testId;

  // All concurrent tests share the same test id. Therefore it is possible to
  // use the lock to ensure that only one process will store the cache. This
  // is important as else DB tables created by one process could be deleted
  // by another as the cache copying is idempotent.

  // Try to copy the installation to the setup cache - now that we have a
  // lock to do so.

    // It is non-fatal if the cache cannot be copied as the next test run
    // will try it again.
