finish yesterday work on rql constraints: * Fix inheritance pb: there are some places where we filter constraints according to the class hierarchy, so rql unique constraint should'nt be neither a RQLContraint nor a RQLVocabularyConstraint subclass. Added test in unittest_schema reflecting this. * So now we have to get explicitly RQLUniqueConstraint where desired (eg in server/hooks.py) * Update i18ncubicweb command to include constraint types in generated pot file (this should have been there for a while...) * Update unittest_schemaserial which has been broken when serializing format for rql constraints has changed

/* -*- 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

    IF LENGTH(vfulltext) < maxsize THEN
       RETURN vfulltext;
    ELSE
       RETURN SUBSTRING(vfulltext from 1 for maxsize) || '...';
