At long last, the fourth and final beta release of ZEO 1.0 is available at http://www.zope.org/Products/ZEO. I expect to release 1.0 final next week. Zope Enterprise Objects (ZEO) provides the ability for multiple processes to use a single Zope Object Database. ZEO turns the Zope object system into a distributed architecture, allowing multiple processors, machines, and networks to act as one website. The 1.0b4 release fixes all the major bugs reported since 1.0b3. The list of bug fixes is: - Improved robustness of ZEO under load. Many non-fatal socket errors are caught and handled now. Also fix NameError bug that could cause ZEO to fail on Windows. - Reduced the likelihood that a thread.error exception ("release unlocked lock") will be raised if a client disconnects from a storage unexpectedly. - Fixed a bug in undo handling that caused connections to be reset and prevented undos from propagating to all clients. - Fixed a bug that prevented a client from reconnecting to a server if the server restarted. - Fixed start.py so that it prints a message on the console when it fails in addition to using zLOG. - Fleshed out installation instructions and version dependencies. - Fixed bug in non-transactional undo that caused undo to fail and clients to restart.
