[js utils] backport some generic code from comments cube
to handle inline ajax form as you get to add comment to entities.
Following stuff has been generalized and backported to ease such things:
* lazy_view_holder() method on EntityCtxComponent class, to build
place holder where the form will be inserted
* ajax_composite_form() function in cw.web.views.ajaxedit, to build
the form itself
* reload() and reloadCtxComponentsSection() javascript function in
cubicweb.ajax.js for the javascript processing side
/* -*- 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 ;;
