Undelete and delete replication

When deleting something, a method will be called for an object 

<?php

$article = new midgard_article(13);

$article->delete();

?>

This could - for the sake of undeleting deleted objects - create a metadata parameter 'metadata.lastaction' = 'delete'.

Chain of actions

  1. delete()
    • sets action to delete
  2. undelete()
    • sets action to update
  3. purge()
    • remove data, leave repligard data
    • Repligard data is used only for replication, so load won't go up

At the moment replication is done based on cron. There is a tool that goes and checks all the data to see which tables have been changed and replicates based on that information.
