Handles tracking, selecting and publishing revisions.

Code

public function getPublishedRevisionId($type, $id) {
  $info = entity_get_info();

  // Get the version ID of the published revision directly from the database.
  // It is not possible to rely on $entity->original here since that does not

  // because we may be in the process of saving it.
