Hello Zope and ZODB users! The folks at Digital Creations, PythonLabs bring to you the second beta release of a Berkeley DB based storage for ZODB. Information about the Berkeley storage, can be found on the Berkeley storage Wiki at http://www.zope.org/Wikis/ZODB/BerkeleyStorage and other ZODB developments can be found on the ZODB Wiki page: http://www.zope.org/Wikis/ZODB/FrontPage This release of the Berkeley storage package contains the Packless.py implementation from 1.0beta1 which provides a non-versioning, non-undoable storage that uses reference counting to eliminate the need for explicit packs (except in the face of object cycles). The 1.0beta2 release adds two new storages: Full.py which is a complete versioning and undoable storage, and Minimal.py which is a rewritten non-versioning, non-undoable storage that will eventually replace Packless.py. Also included is an extensive PyUnit-based test suite. You must install Sleepycat's Berkeley DB 3.2.9 and Robin Dunn's PyBSDDB wrapper package. Berkeley storage 1.0beta2 has been tested with Python 2.0 and 2.1; it may work with Python 1.5.2 but no decision yet has been made whether that will be officially supported. Berkeley storage 1.0beta2 can be installed as a Python distutils package, and works well with StandaloneZODB distribution: http://www.zope.org/Wikis/ZODB/StandaloneZODB It, of course, can also be used with Zope, however please read the release notes concerning undo with the Full.py storage (there's a new non-destructive undo mechanism called Transactional Undo, which is not compatible with Zope 2.3.1 -- Full.py should work with Zope 2.3.1 but you will not be able to undo). Future development will include the integration of cyclic garbage detection with Full.py, and the addition of reference counting and cyclic gc to Minimal.py. See the ZODB Wiki for other developments. The release is available here: http://www.zope.org/Products/bsddb3Storage Discussions should take place on the zodb-dev@zope.org mailing list. Enjoy, -Barry Barry A.
