This needs to find slots defined by the class and its bases, so we can't simply return the __slots__ attribute. We must walk down the Method Resolution Order and concatenate the __slots__ of each class found there. (This assumes classes don't modify their __slots__ attribute to misrepresent their slots after the class is defined.) � __slotnames__Nr r) � __weakref__�__�_z_%s%s)r) r4 ) r) �getr# r" � isinstance�str� startswith�endswithr% �lstrip�appendr3 )r �namesr �slots�name�strippedr r r � _slotnames` s2 rB c C s� t |�}d| kodkn s(td��| |f}tj|�|krPtj|�|krPdS |tkrltd|t| f ��|tkr�td|t| f ��|t|< |t|< dS )zRegister an extension code.r i���zcode out of rangeNz)key %s is already registered with code %sz$code %s is already in use for key %s)�int� ValueError�_extension_registryr7 �_inverted_registry)�moduler@ �code�keyr r r r � s c C sR | |f}t j|�|ks$tj|�|kr4td||f ��t |= t|= |tkrNt|= dS )z0Unregister an extension code.
