I am in the process of converting a largish Python program to Cython.
One thing my software does throughout is to create package-specific
exception types, so that exception handler code can accurately catch
only certain types of exceptions. For example, one subpackage defines
the following exception types:
----
import Crux
class Exception(Crux.Exception):
pass
class ValueError(Exception, ValueError):
def __init__(self, str):
self._str = str
def __str__(self):
return self._str
----
As you can see, this code defines module-specific classes with the same
names as the top-level Python exception types. The Cython compiler
complains with errors like:
/home/jasone/crux/crux/./src/Crux/CTMatrix.pyx:19:0: Assignment to
non-lvalue 'Exception'
Is this a "feature" or a bug in Cython?
Thanks,
Jason
