Re: [Zope-dev] Adapter for class with slots

The minimal reproduction recipe to see the error is this:

class Slotted(object): __slots__ = ('__provides__')

zope.component.provideAdapter( lambda x: True, (Slotted,), zope.interface.Interface)

Which will raise File "/home/wosc/.python-eggs/zope.component-3.7.1-py2.6.egg/zope/component/registry.py", line 419, in _getAdapterRequired elif not ISpecification.providedBy(r): TypeError: 'member_descriptor' object is not callable

Why is this? Can this be made to work? How would I go about investigating that?

It looks to me like a possible bug in zope.interface. Try deleting _zope_interface_coptimizations.so to hopefully expand that traceback. Shane
