The problem with delattr (and thus PyObject_DelAttr) arises when you define a __delattr__ method on your class. There is not easy way to then call back into the "normal" python delattr semantics, except by doing object.__delattr__ (which is not optimized by Cython).
Hmmm, perhaps it should be? And similarly for all the other type slots.
I would argue that there should be at least some way to pass a NULL pointer in Cython where a PyObject* is expected.
The trouble is that supporting this in general both safely and efficiently would require keeping track of which object references are allowed to be NULL. Could be done, but might require quite a lot of work. Maybe something more limited could be done such as allowing a literal NULL to be passed to a function argument that is specially marked as permitting this. -- Greg _______________________________________________ cython-devel mailing list cython-devel@python.org http://mail.python.org/mailman/listinfo/cython-devel
