Code

public function trySoap($function) {
  $args = func_get_args();
  array_shift($args);
  try {
    $results = call_user_func_array(array(
      $this,
      $function,
    ), $args);

    // If returned without exceptions, reset the refreshed flag.
    $this->refreshed = FALSE;
    return $results;
  } catch (SoapFault $e) {

    // sf:INVALID_SESSION_ID is thrown on expired login (and other reasons).
    // Our only recourse is to try refreshing our auth token. If we get any
    // other exception, bubble it up.
    if ($e->faultcode != 'sf:INVALID_SESSION_ID') {
      throw $e;
    }
    if (!$this->refreshed) {

      // If we got an invalid session exception, try to refresh the auth
      // token through REST API. The "refreshed" flag will make sure we retry
      // only once.
      $this->refreshed = TRUE;
      $this->salesforceApi
        ->refreshToken();
      return $this
        ->trySoap($function, $args);
    }

    // If we've already tried a refresh, this refresh token is probably
    // invalid. Kill it, log, and bubble the exception.
    $this
      ->setConnected(FALSE);
    variable_del('salesforce_refresh_token');
    $link = l(t('the Salesforce configuration page'), 'admin/config/services/salesforce');
