# Deprecate or remove this module when no supported version of Django still
# supports Python 2. Until then, keep it to allow pluggable apps to support
# Python 2 and Python 3 without raising a deprecation warning.

Fixed #21351 -- Replaced memoize with Python's lru_cache. Replaced the custom, untested memoize with a similar decorator from Python's 3.2 stdlib. Although some minor performance degradation (see ticket), it is expected that in the long run lru_cache will outperform memoize once it is implemented in C. Thanks to EvilDMP for the report and Baptiste Mispelon for the idea of replacing memoize with lru_cache. 2013-11-02 04:15:41 +08:00
