Zope X3 3.0.0 beta 1 released
by Stephan Richter 05 Jun '04

05 Jun '04

Dear Python community, The Zope 3 development team is proud to announce the first beta release of Zope X3 3.0.0. Zope X3 is the next major Zope release and has been written from scratch based on the latest software design patterns and the experiences of Zope 2. The "X" in the name stands for "experimental", since this release does not try to provide any backward-compatibility to Zope 2. Download http://zope.org/Products/ZopeX3 Installation instructions for both Windows and Un*x/Linux are now available in the top level README.txt of the distribution. Changes to alpha 2 - More packages have been removed from the distribution. This includes the 'session' package and all the packages that deal with Python code inside the ZODB, such as 'zodbcode' and persistent interfaces. - Complete reimplementation of the event system to use subscribers. - Updated the online help system (not to be confused with API doc tool) to reflect the latest APIs and design patterns. - The access log can now be configured via the 'zope.conf' file. - The underlying component lookup machinery has been overhauled. Every Zope thread now knows automatically about the context. This simplified the component lookup API a lot. - Several bug fixes. - The Russian translation was completed and the German one was updated as well. Goals The API is frozen now for X3.0.0. We would like to ask all people to test this release and report any bugs or mis-behaviors! The beta period is scheduled to last for about 1 month. During this month we will try to complete the following tasks: - Fix outstanding bugs. - Optimize critical components to speed up the system. - Write and update documentation. - Add and complete translations. - Remove as many XXX comments as possible. There is still much to do! Even if you are not a programmer, you can help! Please send any bug reports and comments to zope3-dev(a)zope.org! Thank you very much in advance for your help! Contributors Jim Fulton, Marius Gedminas, Fred Drake, Philipp von Weitershausen, Stephan Richter, Dmitry Vasiliev, Scott Pascoe, Bjorn Tillenius, Eckart Hertzler, Roger Ineichen, Stuart Bishop Thanks to everyone!

ruleCore 1.1beta3
by marco＠analog.se 04 Jun '04

04 Jun '04

This release is hopefully the last beta before 1.1 and should be used instead of 1.0. It contains mainly a number of small fixes and better documentation. ruleCore is a kind of rule engine designed for detection of complex patterns of events. RuleCore can be configured to detect a number of interesting patterns in the events that enter the engine. The most obvious ones would be sequences of events, events combined with logical operators (and, or, not). A more advanced use would be to say something about time. For example that a sequence of events must occur within five hours or that a deadline event must come before next tuesday after the occurance of another starting event. The engine can also detect that an event is missing. The complex event detection capability is the main focus of ruleCore and thus there is many things missing. Such as delivery of detection events to subscribers and so on. The main use would then be to use ruleCore as an event detection component in a bigger system. The events, we imagine, are sent to the ruleCore engine from a number of busines systems or other applications with the capability to generate events. Events can be sent to ruleCore through plain TCP/IP sockets (very simple string format), XML-RPC, The IBM WebSphere message queue or the Rendezvous message bus from Tibco Inc. ruleCore home page: www.rulecore.com Download from Sourceforge: www.sourceforge.net/projects/rulecore The business people would call this type of systems for "Business Activity Monitoring" BAM or "Business Event Management" BEM solutions.

my cgipm and std python cgi
by Dave Hastings 03 Jun '04

03 Jun '04

I have added a link to the manual that was created for our new CGI module. I hope this clears up some questions and confusion about the module. http://www.unixbeast.com/CGIpm/vote.cgi . The manual is in PDF format. Please keep in mind the manual, in its current state, was written with the idea that the module was going to be named CGIpm. It will be changed when the new name is set. The module was not intended to be better than or replace the existing cgi module that is built in with python. It is rather an expansion so to speak. All the functions and their definitions are outlined in the manual listed above. Looks like 'CGIpy' is still winning by a bunch ! Dave cgipm(a)unixbeast.com

pyrad 0.7 - native python RADIUS implementation
by Wichert Akkerman 02 Jun '04

02 Jun '04

pyrad is an implementation of a RADIUS client and server as described in RFC2865, 2866, and others. It takes care of all the details like building RADIUS packets, sending and receiving them, and en-/decoding responses. (RADIUS is a common protocol used for authentication, authorisation and accounting for remote access (and similar) services). Changes since previous release ------------------------------ New features on request of Thomas Boettcher from Aachen University: * add HandleAuthPacket and HandleAcctPacket hooks to Server class * Pass on dict attribute when creating a reply packet * Allow specififying new attributes when using Server.CreateReplyPacket Example ------- Here is an example of doing a authentication request: import pyrad.packet from pyrad.client import Client from pyrad.dictionary import Dictionary srv=Client(server="radius.my.domain", secret="s3cr3t", dict=Dictionary("dicts/dictionary", "dictionary.acc")) req=srv.CreateAuthPacket(code=pyrad.packet.AccessRequest, User_Name="wichert", NAS_Identifier="localhost") req["User-Password"]=req.PwCrypt("password") reply=srv.SendPacket(req) if reply.code==pyrad.packet.AccessAccept: print "access accepted" else: print "access denied" print "Attributes returned by server:" for i in reply.keys(): print "%s: %s" % (i, reply[i]) And an example for a trivial RADIUS server: from pyrad import dictionary, packet, server class FakeServer(server.Server): def _HandleAuthPacket(self, fd, pkt): server.Server._HandleAuthPacket(self, fd, pkt) reply=self.CreateReplyPacket(pkt) reply.code=packet.AccessAccept self.SendReplyPacket(fd, reply) srv=FakeServer(dict=dictionary.Dictionary("dictionary")) srv.hosts["127.0.0.1"]=server.RemoteHost("127.0.0.1", "s3cr3t", "localhost") srv.BindToAddress("") srv.Run() Requirements ------------ pyrad requires Python 2.2 or later. Author, copyright, availability ------------------------------- pyrad was written by Wichert Akkerman <wichert(a)wiggy.net> The current version and documentation can be found at its homepage: http://www.wiggy.net/code/pyrad/ Copyright 2002-2004 Wichert Akkerman.

CFP: The 3rd Workshop on Reflective and Adaptive Middleware
by Nanbor Wang 02 Jun '04

02 Jun '04

My sincere apology to those who receive multiple copies. ---------------------------------------------------------------------- CALL FOR PAPERS The 3rd Workshop on Reflective and Adaptive Middleware (RM2004) in conjunction with the 5th International Middleware Conference 2004 Toronto, Ontario, Canada Tuesday October 19, 2004 http://www.txcorp.com/~nanbor/RM2004/ ---------------------------------------------------------------------- Overview -------- Most of the middleware used and developed today is characterised by its inflexibility in adapting to different target environments and application areas. This lack of adaptability usually comes from the fact that middleware is traditionally built as a single monolithic entity. This inflexibility usually can be characterised by either the inability to adapt the behaviour of the platform, the inability to adapt its structure, or even both. In application domains such as mobile computing, distributed multimedia, and distributed real-time and embedded (DRE) systems, where resources are both constrained and variable in time, having the ability to reconfigure the middleware in order to optimise the resource usage and/or provide the desired quality of service (QoS) becomes a key feature. Applying reflective techniques to middleware in order to "open up" the implementation, is one of the ways to provide a greater degree of configurability and dynamic adaptability at the middleware level. In the past few years, researchers have been experimenting with the use of reflection, component-based software engineering, software architecture design patterns and component frameworks, to achieve these goals. Following the success of the past two workshops, RM2004 aims at providing researchers with a leading edge view on the state of the art in reflective and adaptive middleware, and with the challenging problems that remain unsolved. This workshop permits researchers from around the world investigating middleware adaptation to interact and share ideas. It will provide the platform to further the application of adaptive middleware techniques to a variety of domains, such as medicine, command and control, homeland security, entertainment and commerce. Submission Guidelines --------------------- Attendance to the workshop is based on the submission of a position paper, poster, or demo. Position papers should not exceed 6 pages of text using 10 point size type on letter/A4 paper in ACM format. Document templates for most popular document processing tools can be found at http://www.acm.org/sigs/pubs/proceed/template.html. Poster submissions should be accompanied with a 2-page abstract summarizing the poster. Similarly, demo submissions should be in the form of 2-page abstract. Papers and extend abstracts should be emailed to Nanbor Wang at <nanbor(a)txcorp.com> with subject line clearly identifying "RM2004 submission" before submission deadline. All papers and abstracts should be in either PS, PDF or Microsoft Word, format. All workshop papers will be published via ACM's Digital Library. Selected extended, enhanced papers will be invited for publishing in the IEEE Distributed Systems Online. Topics of interest to this workshop include, but not limit to the following: * Design and performance of adaptive reflective middleware platforms * Application of adaptive and reflective middleware techniques to achieve reconfigurability and/or adaptability * Application of adaptive and reflective middleware techniques to achieve separation of concerns * Design of Meta Object Protocols (MOP) for adaptive and reflective middleware * Experiences with adaptive and reflective technologies in suitable application domains e.g., real-time systems, mobile computing, etc. * Fundamental developments in the theory and practice of reflection, as it relates to middleware * Experience with existing mechanisms, such as CORBA portable interceptors, or the OMG Meta- Object Facility * Consideration of alternative techniques for dynamic configuration and/or reconfiguration * Examination of potentially complementary techniques, such as aspect-oriented programming * Techniques to improve performance and/or scalability of adaptive and reflective techniques * Approaches to maintain the integrity of adaptive and reflective technologies * Tool support for adaptive and reflective middleware * Combination of RM and software development techniques, such as design patterns, component frameworks and software architectures * Design and programming abstractions to manage the complexity of reflective and adaptive mechanisms * Composition of systemic aspects and adaptive behaviours into component middleware applications * Abstraction, specification, and modelling of composable systemic aspects and behaviours in component middleware framework. Important Dates --------------- Paper and abstract submission Saturday, July 10, 2004 Acceptance notification Tuesday, August 10, 2004 Final papers due Wednesday, September 1, 2004 Workshop Tuesday, October 19, 2004 Program Committee ----------------- .

new CGI module vote
by Dave Hastings 02 Jun '04

02 Jun '04

My partner and myself have created a new python module that reflects the cgi.pm perl module. The new python module provides functions for HTTP header and environment purposes, HTML forms, and general HTML shortcuts. If you are familiar with the cgi.pm perl module then you should already know what our new python module includes since we tried to incorporate all of the functions. We created this module for people who would really like to use the cgi.pm perl module or who would like the functionality that the perl module provides, but are not enthused to program in perl. We have completed the module. There does remain one thing before we can announce the module on the announce list, it needs a name. We have created a web page (using the new python module) that has a vote on it. I am asking for people to go to http://www.unixbeast.com/CGIpm/vote.cgi and vote on what you think the most fitting name would be. CGIpy seems to be the most popular right now. Once we feel that there are enough votes we will give the winning name to the module and I will again post to the announce list announcing the module itself, and where to download it. Thank you so much for you time - David Hastings cgipm(a)unixbeast.com - Michael Sampson samp0082(a)umn.edu
