PyPy 0.7 is out / first self contained release
by hpk＠trillke.net Aug. 28, 2005

Aug. 28, 2005

pypy-0.7.0: first PyPy-generated Python Implementations ============================================================== What was once just an idea between a few people discussing on some nested mailing list thread and in a pub became reality ... the PyPy development team is happy to announce its first public release of a fully translatable self contained Python implementation. The 0.7 release showcases the results of our efforts in the last few months since the 0.6 preview release which have been partially funded by the European Union: - whole program type inference on our Python Interpreter implementation with full translation to two different machine-level targets: C and LLVM - a translation choice of using a refcounting or Boehm garbage collectors - the ability to translate with or without thread support - very complete language-level compliancy with CPython 2.4.1 What is PyPy (about)? ------------------------------------------------ PyPy is a MIT-licensed research-oriented reimplementation of Python written in Python itself, flexible and easy to experiment with. It translates itself to lower level languages. Our goals are to target a large variety of platforms, small and large, by providing a compilation toolsuite that can produce custom Python versions. Platform, Memory and Threading models are to become aspects of the translation process - as opposed to encoding low level details into a language implementation itself. Eventually, dynamic optimization techniques - implemented as another translation aspect - should become robust against language changes. Note that PyPy is mainly a research and development project and does not by itself focus on getting a production-ready Python implementation although we do hope and expect it to become a viable contender in that area sometime next year. Where to start? ----------------------------- Getting started: http://codespeak.net/pypy/dist/pypy/doc/getting-started.html PyPy Documentation: http://codespeak.net/pypy/dist/pypy/doc/ PyPy Homepage: http://codespeak.net/pypy/ The interpreter and object model implementations shipped with the 0.7 version can run on their own and implement the core language features of Python as of CPython 2.4. However, we still do not recommend using PyPy for anything else than for education, playing or research purposes. Ongoing work and near term goals --------------------------------- PyPy has been developed during approximately 15 coding sprints across Europe and the US. It continues to be a very dynamically and incrementally evolving project with many one-week meetings to follow. You are invited to consider coming to the next such meeting in Paris mid October 2005 where we intend to plan and head for an even more intense phase of the project involving building a JIT-Compiler and enabling unique features not found in other Python language implementations. PyPy has been a community effort from the start and it would not have got that far without the coding and feedback support from numerous people. Please feel free to give feedback and raise questions. contact points: http://codespeak.net/pypy/dist/pypy/doc/contact.html contributor list: http://codespeak.net/pypy/dist/pypy/doc/contributor.html have fun, the pypy team, of which here is a partial snapshot of mainly involved persons: Armin Rigo, Samuele Pedroni, Holger Krekel, Christian Tismer, Carl Friedrich Bolz, Michael Hudson, Eric van Riet Paap, Richard Emslie, Anders Chrigstroem, Anders Lehmann, Ludovic Aubry, Adrien Di Mascio, Niklaus Haldimann, Jacob Hallen, Bea During, Laura Creighton, and many contributors ... PyPy development and activities happen as an open source project and with the support of a consortium partially funded by a two year European Union IST research grant. Here is a list of the full partners of that consortium: Heinrich-Heine University (Germany), AB Strakt (Sweden) merlinux GmbH (Germany), tismerysoft GmbH(Germany) Logilab Paris (France), DFKI GmbH (Germany) ChangeMaker (Sweden), Impara (Germany)

Zope 3.1.0 RC 2 released!
by Stephan Richter Aug. 28, 2005

Aug. 28, 2005

Hello everyone, The Zope 3 development team is proud to announce Zope 3.1.0 candidate 2. Zope 3 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. It is in our opinion that Zope 3.1 is more than ready for production use, which is why we decided to drop the 'X' for experimental from the name. We will also continue to work on making the transition between Zope 2 and Zope 3 as smooth as possible. As a first step, Zope 2.8 includes Zope 3 features in the form of Five. Now that we have a release that we would like to declare stable next week, we are looking for translators, who translate Zope 3 into their favorite language! We are utilizing the Rosetta system from Ubuntu for managing those translations. If you are not familiar with Rosetta, please send us a mail to zope3-dev(a)zope.org and we get you set up. Downloads http://zope.org/Products/Zope3/ Installation instructions for both Windows and Un*x/Linux are now available in the top level 'README.txt' file of the distribution. The binary installer is recommended for Windows. Zope 3.1 requires Python 2.3.5 or 2.4.1 to run. You must also have zlib installed on your system. Changes Since 3.1.0c1 - Removed an untested missfeature that can cause infinite loops in principalfolder's Principal class. - Switch to METAL 1.1, which solved a serious bug. - Grant view cleaned up. - Add missing id attribute to select widget. - pytz has been updated. - Some code optimization in the HTTP factory of the publisher and ftesting framework. - Multiple headers having the same name are correctly handled now. - Now SQL operation parameters will be properly encoded before executing. - More carefully handle case when SQL parameters is a tuple or a list of a tuples. - All request factories can now be configured. - Script and Installation documentation improvements. - Fixed several bugs in API doc. Also provided some flexibility with the UI. - Fix to source widget hasInput and associated changes - Updated Build System. - Fix I18n bugs. Updated Russian and German translations. Most Important Changes Since 3.0 - New Pluggable Authentication Utility (PAU), which is similar in philosophy to the Zope 2 PAS. The following features are available in the in the basic PAU facility: + Credentials Plugins: Basic HTTP Auth, Session + Authenticator Plugins: Principal Folder, Group Folder For a detailed description of the pluggable authentication utility, see 'zope/app/authentication/README.txt'. - Major simplifications to the component architecture: + Removal of the concept of a service. All outstanding services were converted to utilities: Error Reporting, FSSync, Authentication. + Site Managers are global and local now; adapters and utilties are directly registered with the site manager. Now global and local component registration and lookup behaves very similar. + Local registrations can now only have two states: active and inactive. This simplified the code so much, that 'zope.app.utility', 'zope.app.registration' and 'zope.app.site' were all merged into 'zope.app.component'. + Implemented menus as utilities. The API also supports sub-menus now. + Implemented views as adapters. Skins and layers are now simply interfaces that the request provides. - Added an integer-id facility for assigning integer identifiers to objects. - Added basic catalog and index frameworks. - Added "sources", which are like vocabularies except that they support very large collections of values that must be searched, rather than browsed. - Created a new granting UI that allows advanced searching of principal sources. - Implemented a generic user preferences systsem that was designed to be easily used in TALES expressions and via Python code. Preferences can be edited via 'http://localhost:8080/++preferences++/'. A demo of the preferences can be found at:: http://svn.zope.org/Zope3/trunk/src/zope/app/demo/skinpref/ - ZCML now supports conditional directives using the 'zcml:condition' attribute. The condition is of the form "verb argument". Two verbs, 'have feature' and 'installed module' are currently implemented. Features can be declared via the 'meta:provides' directive. - Improved API doctool: Code Browser now shows interfaces, text files and ZCML files; the new Book Module compiles all available doctext files into an organized book; the new Type Module lets you browser all interface types and discover interfaces that provide types; views are shown in the interface details screen; views and adapters are categorized into specific, extended and generic; user preferences allow you to customize certain views; 3rd party modules can now be added to the Code Browser. - Improved I18n-based number and datetime formatting by integrating 'pytz' for timezone support, implementing all missing format characters, and reinterpreting the ICU documentation to correctly parse patterns. - Added '++debug++' traversal adapter that allows you to turn on debugging flags in 'request.debug'. Currently the following flags are defined: source, tal, errors. - Improved logout support. - Added the HTTP request recorder, which lets you inspect raw HTTP requests and responses. It can be used to create functional doctests without requiring third-party tools such as TCPWatch. - Developed a generic 'browser:form' directive. It is pretty much the same as the 'browser:editform' directive, except that the data is not stored on some context or adapted context but sent as a dictionary to special method (by default). For a complete list of changes see the 'CHANGES.txt' file.

ANN: wxBrowser 0.3.0
by Johan Lindberg Aug. 28, 2005

Aug. 28, 2005

wxBrowser 0.3.0 is available for download at SourceForge. Introduction The wxBrowser is an application browser, which is similar to a regular web browser, but it doesn't read HTML to generate and display content; it reads wxwML (XML), generates and dynamically executes wxPython GUI code. GUI events are bound to URLs instead of functions. If an event is triggered the wxBrowser requests a new document from the URL, expecting wxwML back. It translates the wxwML into wxPython code and executes it. See http://www.pulp.se/wx/wxBrowser.pdf for more info Changes This is a complete rewrite of 0.2.5. I added support for "client-side scripting" and the possibility to add and/or customize handling of widgets. Note! This version of the wxBrowser has no "Open URL" dialog so you must enter the URL at the command prompt. Download You can download the python source from SourceForge (http://sourceforge.net/project/showfiles.php?group_id=134835&package_id=148…) and there's a sample application at http://www.pulp.se/wx/contacts/v2 that you can use to test it. More information See: http://sourceforge.net/projects/wxbrowser and http://www.pulp.se/ Disclaimer The wxBrowser is still very "work in progress", there's still lots of things to be done but this version is complete enough to play around with and try out the idea. I haven't had the opportunity to try this version on any other OS than Windows XP. If you do, please let me know what happens. WARNING! By adding client-side scripting I've also made it rather EASY to have the wxBrowser execute "malicious python code" that can possibly harm your computer so please be careful with what applications you point your wxBrowser to. I won't take responsibility for any damages done to your computer by using this software. -- Johan Lindberg, 2005-08-28 johan(a)pulp.se

[ANN] rpncalc-2.0
by Raymond L. Buvel Aug. 20, 2005

Aug. 20, 2005

The rpncalc package adds an interactive Reverse Polish Notation (RPN) interpreter to Python. This interpreter allows the use of Python as an RPN calculator. You can easily switch between the RPN interpreter and the standard Python interpreter. Home page: http://calcrpnpy.sourceforge.net/ Changes in 2.0 * Added function to compute the roots of a polynomial. * Added functions to save and restore the stacks and user variables. * Added clnum package which provides arbitrary precision floats and rationals in both real and complex forms. Also provides the functions in the standard math and cmath libraries in extended precision floating point. * Switched the RPN interpreter to use the clnum package for all operations. The standard Python float and complex are still available but require an explicit conversion. * Switched ratfun so that it requires the clnum package. This simplified some of the code for handling integer coefficients. It also makes it possible to use Laguerre's method for finding the roots of polynomials. * Changed the license to the GPL because the clnum package uses a GPL library.
