Re: [Zope-dev] method attribute __roles__ in Zope 2.8

I can across the following problem while trying to fix the broken FTP service for Zope 2.8:

ObjectManager.manage_FTPstat() tries to access self.manage_FTPlist.__roles__ whose value is ('Manager',') in Zope 2.7. In 2.8 this attribute is not available.

In Zope 2.7 and before, ExtensionClass methods were magic objects. When you used "method.attr", then the method actually used "getattr(method.im_self, method.im_func.func_name+'attr')" to retrieve "attr" (i.e. "attr" where retrieved from the bound object). For the new style ExtensionClass implementation (used from Zope 2.8 on), Jim removed this magic. You can use the "getattr" above to resolve the attribute. -- Dieter
