Products.mcdutils 1.0

A Zope2 product which provides facilities forstoring sessions in memcached.

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.

Change log

1.0 (2019-03-28)

• Zope 4 compatibility

• documentation using Sphinx

• tox configuration for unit, coverage and code quality tests

• package configuration cleanup

• full flake8 compliance

• add ability to set a title for a MemcacheProxy

• add ability to set a title for a MemcacheSessionDataContainer

0.2b3 (2011-11-21)

• Extend MANIFEST.in to include other missing files (.gif, .pt, .txt)

0.2b2 (2011-11-21)

• Fix source distribution by including README.txt and CHANGES.txt via manifest.

• Include test runner in buildout and fix broken tests.

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.

0.1 (2006-05-31)

• CVS tag, ‘mcdutils-0_1’

• Initial public release.
