Session Data Using memcache

This package provides a session data manager which stores it’s data in memcache. The package uses lovely.memcached to store it’s data.

IMPORTANT:

This test expects a memcache server running on local port 11211 which is the default port for memcached.

This test runs in level 2 because it needs external resources to work. If you want to run this test you need to use –all as parameter to your test.

Start a memcache instance with : memcached <optional options>

>>> from zope import component
>>> from lovely.memcached.interfaces import IMemcachedClient
>>> from lovely.memcached.utility import MemcachedClient
>>> util = MemcachedClient()
>>> component.provideUtility(util, IMemcachedClient, name='session')
>>> util.invalidateAll()

Now we create a memcache session and connect it to the memcached client.

>>> from lovely.session.memcached import MemCachedSessionDataContainer
>>> sessionData = MemCachedSessionDataContainer()
>>> sessionData.cacheName = u'session'

We need to provide a name for the session data manager because it is used to identify the cache entry in memcache.

>>> sessionData.__name__ = 'MemCacheSession'

>>> session = sessionData['mySessionId']
>>> session
{}
>>> type(session)
<class 'lovely.session.memcached.MemCacheSessionData'>

We can now get data from the session.

>>> data = session['myData']
>>> data
{}
>>> type(data)
<class 'lovely.session.memcached.MemCachePkgData'>

>>> data['info'] = 'stored in memcache'
>>> data
{'info': 'stored in memcache'}

Because the MemCacheSession is transaction aware we need to commit the transaction to store data in the memcache.

>>> import transaction
>>> transaction.commit()

If we now read session data is is read back from the memcache.

>>> session = sessionData['mySessionId']
>>> session['myData']
{'info': 'stored in memcache'}

>>> sessionData.items()
[('mySessionId', <lovely.session.memcached.DataManager object at ...>)]
