[migration] re-try without print_function when compiling a script fails
As part of the python3 porting we added the __future__.print_function import to
cubicweb.migration. That started affecting all migration scripts it runs,
which may not be prepared. So if compiling a script results in SyntaxError,
try again without the print_function flag.
Closes #7935030
/* -*- 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 ;;
