Django 1.9 cache.get_or_set works incorrectly with DummyCache backend

[Oleksiy Ivanenko]

Hi,

I'm trying to use Django 1.9rc2
There is some issue when you use django.core.cache.cache.get_or_set with DummyCache backend.

from django.core.cache import cache

cache.get_or_set('some_key', 'my_val')  # Always returns None. Not a default value

This thing brakes all my tests, when I use DummyCache.

Is this behaviour expected?
Or we need to figure out how to handle it?

It seems to be an omission in the implementation. Feel free to create a Trac ticket and offer a patch if you can.

For future reference, please don't cross post between django-users (appropriate place for "is it a bug?" questions) and django-developers. Thanks!
