Create an infinite loop by causing a watchdog message to be set, which causes the actions to be triggered again, up to actions_max_stack times.

Class

ActionLoopTestCase

Test actions executing in a potential loop, and make sure they abort properly.

Code

protected function triggerActions() {
  $this->drupalGet('<front>', array('query' => array('trigger_actions_on_watchdog' => TRUE)));
  $expected = array();
  $expected[] = 'Triggering action loop';
  for ($i = 1; $i <= variable_get('actions_max_stack', 35); $i++) {
    $expected[] = "Test log #$i";
  }
  $expected[] = 'Stack overflow: too many calls to actions_do(). Aborting to prevent infinite recursion.';

  $result = db_query("SELECT message FROM {watchdog} WHERE type = 'actions_loop_test' OR type = 'actions' ORDER BY wid");
  $loop_started = FALSE;
  foreach ($result as $row) {
    $expected_message = array_shift($expected);
    $this->assertEqual($row->message, $expected_message, t('Expected message %expected, got %message.', array('%expected' => $expected_message, '%message' => $row->message)));
  }
  $this->assertTrue(empty($expected), t('All expected messages found.'));
}
