memcached. This means testing with local dev caches (not memcache) will warn developers if they are introducing inadvertent importabilities. There is also the ability to silence the warning if a dev is not planning to use memcache and knows what they are doing with their keys. Thanks to Carl Meyer for the patch. Fixed #6447. Backport of r13766 from trunk. git-svn-id: http://code.djangoproject.com/svn/django/branches/releases/1.2.X@13767 bcc190cf-cafb-0310-a4f2-bffc1f526a37
