Zope 3.4.0 Released!
by Stephan Richter 31 Jan '09

31 Jan '09

January 29, 2009 - The Zope 3 development team announces the Zope 3.4.0 release. After 2 years of development, the Zope Foundation and the larger Zope community is proud to announce the release of Zope 3.4.0. The focus of the Zope 3.4 development effort has been the conversion from a monolithic source tree, to a set of many small packages (eggs), that can be used independently of each other. The core has been further stabilized through numerous bug fixes, and many new add-on packages have been developed to provide a richer development experience. With this release also comes a renewed commitment to a short and reliable release cycle of 6 months. Packages and Eggs ----------------- Zope 3 is now fully converted to an egg-based system. While some work still remains, it integrates very well with the rest of the Python community. The conversion to egg-based packaging also enables other Python developers to only have to use small bits and pieces of the complete Zope software system. The conversion means that Zope 3 developers do not use the classic Zope 3 tar-ball release anymore. However, for your convenience, Zope 3 developers will provide the classic Zope 3 tar ball releases for at least the 3.4 series and probably for 3.5 as well. So how are Zope 3 applications built using only eggs? The Known Good Set (KGS) ~~~~~~~~~~~~~~~~~~~~~~~~ The known good set -- or in short KGS -- is a configuration of packages and their versions that are known to work well together. The compatibility is frequently verified by running over twelve thousand tests on a daily basis [1]_. The KGS is tested against Python 2.4 and 2.5 on the 32- and 64-bit platforms. The list of controlled packages and their versions for Zope 3.4 can be found at the Zope 3 KGS site [2]_. The KGS can be used in several ways [3]_. The most common way is to "nail" the versions by downloading the version configuration file [4]_ and insert them as follows in your buildout configuration:: [buildout] versions = versions ... [versions] zope.interface = 3.4.0 ... ``zopeproject`` Project Builder ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ To start building a project using a common setup, a package called `zopeproject` can be used to quickly setup the boilerplate for the project. Ample documentation is provided at the `zopeproject` home page [5]_. `zopeproject` uses Paste or ZDaemon to create a working server. The following commands get you started:: $ easy_install zopeproject $ zopeproject HelloWorld $ cd HelloWorld $ bin/helloworld-ctl foreground Demo Packages ~~~~~~~~~~~~~ At this point, there is no demo package demonstrating a simple Zope 3 application setup. However, the ``z3c.formdemo`` package can be used as a fairly minimal setup. To get started with it, enter the following:: $ svn co svn://svn.zope.org/repos/main/z3c.formdemo/tags/1.5.3 formdemo $ cd formdemo $ python bootstrap.py $ ./bin/buildout -v $ ./bin/demo fg ..

The binary installer is recommended for Windows. Zope 3.4 requires Python 2.4 or 3.5 to run. You must also have zlib installed on your system. Resources --------- - Zope 3 Development Web Site: http://wiki.zope.org/zope3 - Zope 3 Developers Mailing List: http://mail.zope.org/mailman/listinfo/zope-dev Retired: http://mail.zope.org/mailman/listinfo/zope3-dev - Zope 3 Users Mailing List: http://mail.zope.org/mailman/listinfo/zope-users - Bug tracker at launchpad: https://launchpad.net/zope3 - IRC Channel: #zope3-dev at irc.freenode.net About Zope 3 ------------ Zope 3 is a web application server that continues to build on the heritage of Zope. It was rewritten from scratch based on the latest software design patterns and the experiences of Zope 2. The component architecture is the very core of Zope 3 that allows developers to create flexible and powerful web applications. Compatibility with Zope 2 ~~~~~~~~~~~~~~~~~~~~~~~~~ Zope 3 is not upwards compatible with Zope 2. This means you cannot run Zope 2 applications in Zope 3. We continue to work on the transition from Zope 2 to Zope 3 by making Zope 2 use more and more of the Zope 3 infrastructure. This means that new code written in Zope 2 can benefit from Zope 3 technology. Also, with care, code can be written that works in both Zope 3 and Zope 2. This allows a Zope 2 application to slowly evolve towards Zope 3. Unchanged Zope 2 applications are never expected to work in Zope 3, however. About the Zope Foundation ------------------------- The Zope Foundation, based in Fredricksburg, Virginia, is a not-for-profit organisation that provides support for the Zope community and the Zope platform and its associated software. Its community includes the open source community of contributers as well as the community of businesses and organizations that use Zope.

ANN: Release of version 2.0 of the discrete event simulation package SimPy
by kgmuller 29 Jan '09

29 Jan '09

We are happy to announce the release of SimPy 2.0, a major new version. Download from: https://sourceforge.net/project/showfiles.php?group_id=62366&release_id=6374 17 Your feedback (errors found, proposals for changes, etc.) is requested, using the SimPy Users Mailing List (simpy-users {at}lists.sourceforge.net). SimPy 2.0 requires Python 2.3 or later. It does not yet run under Python 3.0. The release of a SimPy version for Python 3.0 is planned for later in 2009. What is SimPy? -------------- SimPy is a process-based discrete-event simulation language based on standard Python and released under the GNU LGPL. It provides the modeller with components of a simulation model. These include processes, for active components like customers, messages, and vehicles, and resources, for passive components that form limited capacity congestion points like servers, checkout counters, and tunnels. It also provides monitor variables to aid in gathering statistics. Simpy comes with extensive documentation, tutorials and many example models. SimPy provides plotting and a GUI capability "out of the box". What is new in SimPy 2.0? ------------------------- Object Oriented API =================== In addition to its existing API, SimPy now also has an object oriented API. The additional API - allows running SimPy in parallel on multiple processors or multi-core CPUs, using Parallel Python. - supports better structuring of SimPy programs, - allows easy extension of model classes by sub-classing, thus providing a capability for developing application libraries, - allows subclassing of class *Simulation* and thus provides users with the capability of creating new simulation modes/libraries like *SimulationTrace*, and - reduces the total amount of SimPy code, thereby making it easier to maintain. Note that the OO API is in addition to the old API. SimPy 2.0 is fully backward compatible. Debugging with GUI ================== A new debugging and teaching tool has been added. With the SimulationGUIDebug library, SimPy now supports the user-driven event stepping through models. Windows show the event list and the status of Process and Resource instances. This powerful tool has been provided by Brian Jacobs, Kip Nicol and Logan Rockmore, a group of senior students of Professor Matloff at U. of California at Davis. Documentation ============= SimPy's documentation has been expanded, restructured and processed by the Sphinx documentation generation tool. This has generated one coherent, well structured HTML document which can be easily browsed. A search capability is included. Acknowledgments --------------- SimPy 2.0 has been primarily developed by Stefan Scherfke and Ontje Lünsdorf, starting from SimPy 1.9. Their work has resulted in a most elegant combination of an object oriented API with the existing API, maintaining full backward compatibility. It has been quite easy to integrate their product into the existing SimPy code and documentation environment. Thanks, guys, for this great job! SimPy 2.0 is dedicated to you! The many contributions of the SimPy user and developer communities are of course also gratefully acknowledged. Download, test, enjoy and give us feedback! Happy SimPying! Klaus Muller Tony Vignaux
