Code

function _metatag_isdefaultrevision($entity) {

  // D7 "Forward revisioning" is complex and causes a node_save() with the
  // future node in node table. This fires hook_node_update() twice and cause
  // abnormal behaviour in metatag.
  //
  // The steps taken by Workbench Moderation is to save the forward revision
  // first and overwrite this with the live version in a shutdown function in
  // a second step. This will confuse metatag. D7 has no generic property
  // in the node object, if the node that is updated is the 'published' version
  // or only a draft of a future version.
  //
  // This behaviour will change in D8 where $node->isDefaultRevision has been
  // introduced. See below links for more details.

  // Every moderation module saving a forward revision needs to return FALSE.
  // @todo Refactor this workaround under D8.
  // Workbench Moderation v1 uses the hook_node_presave() for some custom logic.
  // This was replaced with hook_entity_presave() in v3, so only proceed if the
  // old hook implementation is present.
