Can't configure memcached backend to use unix socket

[munhitsu]

So far unix socket is the only way to apply access control on memcached daemon:

memcached -m 16 -s memcached.sock

At this point django expects memcached to be on "server:port".
Can you extend it to also support files?

settings.py:

CACHE_BACKEND = 'memcached://../memcached.sock/?timeout=' +str(TIMEOUT)+ '&max_entries=' +str(MAXENTRIES)

Exception:

File "/vhost/cr3studio/cr3studio/django_site/django/django/core/cache/backends/memcached.py", line 17, in __init__
    self._cache = memcache.Client(server.split(';'))
TypeError: expected "server:port" but "../memcached.sock" found

PS: you can assign it to me :)

Third party issue: cmemcache.

In fact python-memcached seems to be also affected.
Still testing.

Try:

CACHE_BACKEND = 'memcached://unix:memcached.sock'

I use:

memcached -u nobody -s /tmp/memcached.sock -a 0777

My settings.py:

CACHE_BACKEND = 'memcached://unix:/tmp/memcached.sock'

It works.

Replying to seifert:

Which python memcached module are you using?

Replying to munhitsu:

I use python-memcached.

I use python-memcached.

In python-memcache 1.40, the setting you suggest fails with the following exception:

ValueError: invalid literal for int() with base 10: '/tmp/memcached.sock'

However, it does work with python-memcache 1.43, the latest at this time.

Since python-memcache consists of but one file, memcache.py, I suggest that you ship the appropriate version of this file as part of your site's code, with the sys.path properly set so that it's your shipped version that gets imported by Django rather than that of the system.

The resolution of this ticket requires no code change in Django, but the documentation should probably be updated to mention this possibility. What do you think, Django people?
