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% )r1 � __weakref__�__�_z_%s%s) r1 �getr( r' r* �str� startswith�endswithr- �lstrip�appendr= )r �namesr �slots�name�strippedr r r � _slotnamesm s6 ��rK c C s� t |�}d| krdkstd�� td��| |f}t�|�|kr*t�|�|kr*dS |tv r8td|t| f ��|tv rFtd|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_registryrA �_inverted_registry��modulerI �code�keyr r r r � s& � � � r c C sV | |f}t �|�|kst�|�|krtd||f ��t |= t|= |tv r)t|= dS dS )z0Unregister an extension code.
