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' �getr! r � isinstance�str� startswith�endswithr# �lstrip�appendr1 )r �namesr �slots�name�strippedr r r � _slotnames` s2 r@ c C s� t |�}d| kr dks&n td��| |f}t�|�|krNt�|�|krNdS |tkrjtd|t| f ��|tkr�td|t| f ��|t|< |t|< dS )zRegister an extension code.� i���zcode out of rangeNz)key %s is already registered with code %sz$code %s is already in use for key %s)�int� ValueError�_extension_registryr5 �_inverted_registry)�moduler> �code�keyr r r r � s c C sR | |f}t �|�|ks$t�|�|kr4td||f ��t |= t|= |tkrNt|= dS )z0Unregister an extension code.
