XXX Some comments by Seb:
- it is not designed to work for modules with thousands of objects,
so it totally unusable when you have millions of objects
- it is totally unsafe. There is even such code inside :
self.manage_delObjects(id of original object)
commit()
self._setObject(new object instance)
So it is possible to definitely loose data.
- There is no proof that upgrade is really working. With such a
dangerous operation, it would be much more safer to have a proof,
something like the "fix point" after doing a synchronization. Such
checking should even be done before doing commit (like it might
be possible to export objects in the xml format used for exports
before and after, and run a diff).
