[controller] UndoController: fix output method (closes: #1776091)
Fix buggy direct output in `UndoController.publish()`.
Raise now a ValidationError instead of malformed string
Changes:
* raise ValidationError when an error occured in undo
* use the new message mechanism based on _cwmsgid
If errors are not fatal, you have to change publish() method.
/* -*- sql -*-
mysql specific registered procedures,

/* XXX limit_size version dealing with format as postgres version does.
XXX mysql doesn't support overloading, each function should have a different name
NOTE: fulltext renamed since it cause a mysql name conflict
*/
CREATE FUNCTION text_limit_size(vfulltext TEXT, maxsize INT)
RETURNS TEXT
NO SQL
BEGIN
IF LENGTH(vfulltext) < maxsize THEN
RETURN vfulltext;
ELSE
RETURN SUBSTRING(vfulltext from 1 for maxsize) || '...';
END IF;
