Decorator to wrap callable with memoizing function using cache. Repeated calls with the same arguments will lookup result in cache and avoid function evaluation. If name is set to None (default), the callable name will be determined automatically. When timeout is set to zero, function results will not be set in the cache. Cache lookups still occur, however. Read :doc:`case-study-landing-page-caching` for example usage. If typed is set to True, function arguments of different types will be cached separately. For example, f(3) and f(3.0) will be treated as distinct calls with distinct results. The original underlying function is accessible through the __wrapped__ attribute. This is useful for introspection, for bypassing the cache, or for rewrapping the function with a different cache. An additional `__cache_key__` attribute can be used to generate the cache key used for the given arguments. Remember to call memoize when decorating a callable. If you forget, then a TypeError will occur. :param str name: name given for callable (default None, automatic) :param float timeout: seconds until the item expires (default 300 seconds) :param int version: key version number (default None, cache parameter) :param bool typed: cache different types separately (default False) :param str tag: text to associate with arguments (default None) :param set ignore: positional or keyword args to ignore (default ()) :return: callable decorator zname cannot be callablec � �� ��� ��t � � � fn�f�t � � � � ���� �fd�� � ���� fd�}|�_ �S )z3Decorator created by memoize() for callable `func`.Nc �� �� � j | i |��}�� |t � d�� � }|t u r: �| i |��}�du p�t k p�dk }|r�� ||�� �d�� � |S )z:Wrapper for callable to cache arguments and return values.T)r8 Nr )r7 r8 )� __cache_key__r r r r? ) �argsrb r4 �result� valid_timeout�funcr r7 r r. �wrappers ������r ro z7DjangoCache.memoize.<locals>.decorator.<locals>.wrapper� s� �� � ,�g�+�T�<�V�<�<�� ���#�v�w�d��C�C���V�#�#� !�T�4� 2�6� 2� 2�F� �4�� '�"�o�5�'�"�Q�;� "� %� � ��� � "� #� #� #�"&� !� � � � � r c �* �� t �| |��� � S )z,Make key for cache given function arguments.)r )rk rb �base�ignore�typeds ���r rj z=DjangoCache.memoize.<locals>.decorator.<locals>.__cache_key__� s �� �"�4��v�u�f�E�E�Er )r r rj ) rn rj rq ro rr r% r r7 r rs r. s ` @@�������r � decoratorz&DjangoCache.memoize.<locals>.decorator� s� ����� �)-� �I�d�O�O�%�%�D�7�D� �4�[�[� � � � � � � � � � �[� �0 F� F� F� F� F� F� F� %2�G� !��Nr )�callable� TypeError)r r% r r. rs r7 rr rt s ``````` r �memoizezDjangoCache.memoizer si �������� �^ �D�>�>� 7�� 5�6�6� 6�" � " � " � " � " � " � " � " � " � " � " �H �r )N)NNFFFF)NNFFT)NT)r NNT)TF) �__name__� __module__� __qualname__�__doc__r �propertyr r# r) r+ r r2 r r6 r? rA rC rE rG rM rO rQ rU rW rY r[ r] r_ ra r1 rw � __classcell__)r s @r r r s� �� � � � � �7�7� I� I� I� I� I� �%� %� �X�%�'� '� '�6� 6� 6� 6�'� '� '� �� � �� F� F� F� F�F �� �� ��L� L� L� L�: %� %� %� %� �� � ��F� F� F� F�: "1�$�d� 6� 6� 6� 6�( ��� ��F� F� F� F�8 .� .� .� .�C� C� C� C�:?� ?� ?� ?�8 "� "� "� "�$� $� $�=� =� =� =�'� '� '�%� %� %�&� &� &�"� "� "�#� #� #� � � � +:� 4� 4� 4� 4� � ��� ��V� V� V� V� V� V� V� Vr r N)r{ � functoolsr � django.core.cache.backends.baser r � ImportError�corer r r �fanoutr r rf r r �<module>r� s� �� 3� 3� � � � � � � 5� 5� 5� 5� 5� 5��?�?�?�?�?�?�?��� � � ��O�O�O����� 1� 0� 0� 0� 0� 0� 0� 0� 0� 0� � � � � � �w� w� w� w� w�)� w� w� w� w� ws � �!�!
