Johnny-cache on Heroku

Hi, today i got the awesome caching library for Django johnny cache working on heroku.

What you will need
1. My fork of johnny cache that adds a new cacheing backend with support for
django-pylibmc-sasl==0.2.4
pylibmc==1.2.3
2. A heroku memcachier addon
3. The settings.

STEP 1
For development install my fork locally

pip install git+git://github.com/grillermo/johnny-cache.git

Now add these lines to your requirements.txt, at the end of it

git+git://github.com/grillermo/johnny-cache.git

django-pylibmc-sasl==0.2.4
pylibmc==1.2.3


STEP 2
Install the addon on your app

heroku addons:add memcachier:dev --app yourHerokuApp

STEP 3

Add these to your settings file

    os.environ['MEMCACHE_SERVERS'] = os.environ.get('MEMCACHIER_SERVERS', '')
    os.environ['MEMCACHE_USERNAME'] = os.environ.get('MEMCACHIER_USERNAME', '')
    os.environ['MEMCACHE_PASSWORD'] = os.environ.get('MEMCACHIER_PASSWORD', '')

    CACHES = {}
    CACHES['default'] = {
            'BACKEND': 'johnny.backends.memcached.PyLibMCCacheSasl',
            'BINARY': True,
            'JOHNNY_CACHE': True,
            'LOCATION': 'localhost:11211',
            'OPTIONS': {
                'ketama': True,
                'tcp_nodelay': True,
            },
            'TIMEOUT': 500,
        }
    JOHNNY_MIDDLEWARE_KEY_PREFIX='a_nice_string_of_your_choosing'

    # The first middleware on the list

    MIDDLEWARE_CLASSES = (
        'johnny.middleware.LocalStoreClearMiddleware',
        'johnny.middleware.QueryCacheMiddleware',
        ...
    ) 

By all means if you encounter problems, contact me @grillermo or leave a comment here, i suffered this installation and my experience could help somebody in need.

On a related issue i couldnt uninstall already installed packages by pip so i had to fix my buildpack so heroku respects these command
heroku labs:enable user_env_compile --app bandtastic
heroku config:add CLEAN_VIRTUALENV=true
What these will do is make heroku reinstall all the packages from your requirements.txt everytime you push, so make sure you only do this once you update your johnny cache installation with my repo and then you should do

heroku config:remove CLEAN_VIRTUALENV

To go back to normality
To use my build pack run
heroku config:add BUILDPACK_URL=git://github.com/grillermo/heroku-buildpack-python.git

 UPDATE

DONT DO IT, do not install johnny cache on heroku, at least using Memcachier this is my new relic performance log

 Look at that! wtf im using the C client pylibmc,  response time almost trippled!
