[issue44310] lru_cache memory leak

[Pablo Galindo Salgado]

Pablo Galindo Salgado <pablogsal at gmail.com> added the comment:

Using a weak dictionary is not a correct solution as the cache must take string ownership of the arguments and return value to do it's job properly. Moreover, there are many types in Python that don't support weak references so this will be a backwards incompatible change and limiting the cache quite a lot.
