I've released version 1.2 of the Spread Module for Python: http://www.python.org/other/spread/ About the Spread Module ----------------------- This package contains a simple Python wrapper module for the Spread toolkit (see below). The wrapper is compatible with Python 2.1 and 2.2. It wraps Spread mailboxes and messages in Python objects with appropriate methods and attributes, and turns Spread errors into Python exceptions. Virtually all Spread features are accessible from Python. About Spread ------------

From the Spread website (http://www.spread.org):

Spread is a toolkit that provides a high performance messaging service that is resilient to faults across external or internal networks. Spread functions as a unified message bus for distributed applications, and provides highly tuned application-level multicast and group communication support. Spread services range from reliable message passing to fully ordered messages with delivery guarantees, even in case of computer failures and network partitions. Spread is designed to encapsulate the challenging aspects of asynchronous networks and enable the construction of scalable distributed applications, allowing application builders to focus on the differentiating components of their application. Changes since release 1.2 ------------------------- - Changed internal uses of Python's object memory API to stop using macro versions of the names (that worked fine, but was dubious practice for non-core extension modules). - Changed mbox.disconnect() to be as safe as possible when SPREAD_DISCONNECT_RACE_BUG is not defined. - Added a test to ensure than the scenario described below doesn't deadlock (two threads in a process sharing an mbox, and one thread doing mbox.receive() waiting for the other thread to do mbox.multicast()). This test deadlocks with high probability if you define SPREAD_DISCONNECT_RACE_BUG. - SPREAD_DISCONNECT_RACE_BUG is turned off, although Spread 3.16.2 still suffers the insecurity it was guarding against. Alas, the workaround can cause deadlocks, depending on how the app uses Spread. Enjoy! --Guido van Rossum (home page: http://www.python.org/~guido/)
