9324	cmemcache and python-memcache hashing differences	Ludvig Ericson	nobody	"There needs to be support for decidedly using either ''only'' python-memcached or cmemcache.

The reason being that the two libraries hash different ways - if you have a box with cmemcache and two without, one of those boxes will store sessions on a different memcached than the other two.

I'm not sure what to do about it, but Malcolm wants documentation and/or a setting with which you can tell Django ""use only this library"" and fail if it isn't found.

Arguably, this should be something that the two libraries come together on, but at least solving it on our part would be nice.

It might be relevant that I've made a hackesque module which monkey patches python-memcached to hash the same way as cmemcache, see http://pypi.python.org/pypi/cmemcache_hash"		closed	Core (Cache system)	dev		wontfix			Accepted	0	0	0	0	0	0
