[cwvreg] cleanup the event manager when reloading modules
Closes #3848995
The event manager callbacks are not cleaned during reloading.
So the callback defined in the reloaded module appears twice (old and new
version). This may cause problem when the old version is called.
/* -*- 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;
END ;;
