A Zope2 product which provides facilities forstoring sessions in memcached.
Project description
Products.mcdutils
The Products.mcdutils product supplies a replacement for the ZODB-based session data container supplied by the Transience product, shipped with the Zope core prior to Zope 4 and available as a separate package after that. Rather than using a ZODB storage as the backing store for session data, as Transience does, Products.mcdutils stores session data in a cluster of one or more memcached servers.
This approach is a bit of a cheat, as it uses the daemons as primary stores, rather than as caches for results of an expensive query. Nevertheless, the semantics are not a bad match for typical session usage.

0.2b1 (2011-11-19)
Turn product into an egg and release on PyPI.
Implement a forced refresh of the in-process cache of memcache data at the end of transactions to avoid stale data.
mapping.py: Added ‘getContainerKey’ method to ‘MemCacheMapping’ in order to make it compatible with the API of the TemporaryFolder version (allows the session testing rig code can generate error messages).
Added (preliminary) RAMCacheManager replacement.
Removed proxy’s ‘create’ method, to allow other multiple of data to be stored. The session data container now handles instantiating the mapping.
Fixed the pickling of mappings correctly, instead of requiring that the proxy pick out the ‘data’ member.
Expanded API for IProxy to expose more of the memcached client API.
