ANN: OSE 7.0 finally available.
by grahamd＠dscpl.com.au Oct. 31, 2001

Oct. 31, 2001

After almost a year of beta releases, OSE 7.0 is finally available. At its core, OSE is a C++ class library for general purpose programming, but also includes support for building event driven systems and distributed applications using a request/reply and publish/subscribe style service agent framework. The ability to interact with an application is facilitated using a HTTP servlet framework and RPC over HTTP interfaces. In short, OSE could be said to take technology from event driven real time systems, message oriented middleware, application server and web service technology and wraps it all into one. Although C++ at its core, OSE also provides wrappers for the Python programming language. This mix means that OSE serves as a useful platform for building standalone or distributed applications in Python, C++ or a mix of both. Its support of both XML-RPC and SOAP protocols through a single service interface makes it ideal for building web based services. Further information on OSE and the software itself, can be found at: http://ose.sourceforge.net This includes over 100 pages of documentation on the Python interfaces alone. The Python documentation can be viewed on the site as HTML, or as a single PDF file at: http://ose.sourceforge.net/python-manual.pdf OSE is released under the QPL. This release is the culmination of over 10 years of development, OSE first being available over the Internet in 1993.

[ANN] MoinMoin 0.10
by J�rgen Hermann Oct. 30, 2001

Oct. 30, 2001

A WikiWikiWeb is a collaborative hypertext environment, with an emphasis on easy access to and modification of information. MoinMoin is a Python WikiClone that allows you to easily set up your own wiki, only requiring a Web server and a Python installation (1.5.2, 1.6 or 2.0). The most prominent change of this release is a fix for a UNIX time billenium bug (affecting RecentChanges sorting and page diffs). See below for a list of new features that were integrated since the last release. Following version 0.10, there will be some major refactorings regarding storage and output generation (see TODO for details). This version is still Python 1.5.2 compatible, but it's not extensively tested for that version and some parts of the system might not work there, especially seldom used macros and actions. Bug reports welcome! Homepage: http://moin.sourceforge.net/ Download: http://sf.net/project/showfiles.php?group_id=8482&release_id=59369 http://prdownloads.sourceforge.net/moin/ Mailing lists: http://lists.sourceforge.net/lists/listinfo/moin-user http://lists.sourceforge.net/lists/listinfo/moin-devel New features: * "#deprecated" processing instruction * config entry "SecurityPolicy" to allow for customized permissions (see "security.py" for more) * added distutils support * though not extensively tested, the standalone server now does POST requests, i.e. you can save pages; there are still problems with persistent global variables! It only works for Python >= 2.0. * "bang_meta" config variable and "!NotWikiWord" markup * "url_mappings" config variable to dynamically change URL prefixes (especially useful in intranets, when whole trees of externally hosted documents move around) * setting "mail_smarthost" and "mail_from" activates mailing features (sending login data on the UserPreferences page) * very useful for intranet developer wikis, a means to view pydoc documentation, formatted via a XSLT stylesheet, for details see http://purl.net/wiki/python/TeudViewer?module=MoinMoin.macro.TeudView or MoinMoin/macro/TeudView.py * "LocalSiteMap" action by Steve Howell <showell(a)zipcon.com> * Added FOLDOC to intermap.txt Bugfixes: * Full config defaults, import MoinMoin now works w/o moin_config.py * Better control over permissions with config.umask * Bugfix for a UNIX time billenium bug (affecting RecentChanges sorting and page diffs) * data paths with directory names containing dots caused problems

mimedecode.py version 1.1
by Oleg Broytmann Oct. 30, 2001

Oct. 30, 2001

Hello! mimedecode.py WHAT IS IT Mail users, especially in non-English countries, often find that mail messages arrived in different formats, with different content types, in different encodings and charsets. Usually this is very good because it allows us to use apropriate formats/encodings/whatever. Sometimes, though, some unification is desireable. For example, one may want to put mail messages into an archive, make HTML indicies, run search indexer, etc. In such situations converting messages to text in one character set and skipping some binary atachmetnts will be much desireable. Here is the solution - mimedecode.py. This is a program to decode MIME messages. The program expects one input file (either on command line or on stdin) which treated as an RFC822 mesage, and decoded to stdout. If the file is not an RFC822 message the file just piped to stdout one-to-one. If it is a simple RFC822 message it is just decoded as one part. If it is a MIME message with multiple parts ("attachments") all parts decoded. Decoding can be controlled by command-line options. WHAT'S NEW in version 1.1.0 Continuation parameters (RFC2231) are now fully supported. WHERE TO GET Master site: http://phd.pp.ru/Software/Python/#mimedecode Faster mirrors: http://phd.by.ru/Software/Python/#mimedecode http://phd2.chat.ru/Software/Python/#mimedecode Requires: Python 2.0+ (actually tested with 2.1.1), configured mailcap database.

High-level parallelization in Python
by Konrad Hinsen Oct. 30, 2001

Oct. 30, 2001

The current development version of Scientific Python contains an experimental package for high-level parallelization. It is based on the Bulk Synchronous Parallel (BSP) paradigm (see www.bsp-worldwide.org for more information), which is much simpler than the more popular message-passing paradigm and also safer, especially due to the impossibility of deadlocks. The main initial goal of the Python BSP package is a well-integrated Pythonesque implementation of BSP that makes parallel programming accessible to a wider range of developers. Performance has been a secondary criterion until now and can certainly be improved, but the current implementation is quite usable for coarse-grained parallelism. The package is labelled "experimental" because it has only been tested with a very small number of applications; future experience may lead to modifications that are not necessarily fully compatible with the current release. Scientific Python 2.3.1 is available from ftp://dirac.cnrs-orleans.fr/pub/ScientificPython/ScientificPython-2.3.1.tar.gz Prerequisites are Python 1.5.2 or higher (2.1 recommended for full access to all features) and an MPI implementation. A tutorial is included, but can also be obtained separately from http://dirac.cnrs-orleans.fr/programs/BSP_Tutorial.pdf -- ------------------------------------------------------------------------------- Konrad Hinsen | E-Mail: hinsen(a)cnrs-orleans.fr Centre de Biophysique Moleculaire (CNRS) | Tel.: +33-2.38.25.56.24 Rue Charles Sadron | Fax: +33-2.38.63.15.17 45071 Orleans Cedex 2 | Deutsch/Esperanto/English/ France | Nederlands/Francais -------------------------------------------------------------------------------

MacPython 2.2b1 released
by Jack Jansen Oct. 30, 2001

Oct. 30, 2001

MacPython 2.2b1 has been released. This is a beta distribution which will undoubtedly still contain bugs. Installers in various forms can be downloaded via http://www.cwi.nl/~jack/macpython.html . Python is a high-level programming language that is suitable for simple scripting tasks as well as writing large applications. MacPython offers a lot of Mac-specific extensions, including access to all major MacOS Toolbox modules (QuickDraw, QuickTime, AppleScript and many more), an Integrated Development Environment (in Python!), frameworks for windowing applications, unix-compatible cgi-scripting, image-manipulation libraries, numerical libraries, tk-based machine independent windowing and lots more. It also uniquely among Pythons allows you to create fully selfcontained (and, hence, distributable) applications without needing a C compiler or anything. What's new in MacPython 2.2? - Types and classes are unified, so you can subclass builtin types. - Iterators and generators allow objects to be "looped over" and producer/consumer-style programming. - Accept both unix- and mac-style newlines - Automatic garbage collection - Better Carbon support and better integration with OS X command line Python Known problems with 2.2b1: - Does not work on Mac OS X multiprocessor machines. - BuildApplication fails for programs using packages. -- Jack Jansen | ++++ stop the execution of Mumia Abu-Jamal ++++ Jack.Jansen(a)oratrix.com | ++++ if you agree copy these lines to your sig ++++ www.cwi.nl/~jack | ++++ see http://www.xs4all.nl/~tank/ ++++

[ANN] 'dbdoc' database schema documentation generator
by Steve Purcell Oct. 29, 2001

Oct. 29, 2001

If you have ever wanted javadoc-style HTML documentation for your database schemas, or a consistent way of programatically inspecting a database schema, then 'dbdoc' may interest you. This small project defines a simple Python API for inspecting database schemas, and uses it to generate documentation (optionally incorporating descriptive text placed in an auxiliary file). Support is initially provided for PostgreSQL. Would anyone like to volunteer to implement the schema introspection API for another database? If so, get in touch! To find out more, please visit http://dbdoc.sourceforge.net/ , where dbdoc has just seen its fourth release. Best wishes to all, -Steve -- Steve Purcell, Pythangelist Get testing at http://pyunit.sourceforge.net/

ANN: Anygui 0.1a3
by Magnus Lie Hetland Oct. 25, 2001

Oct. 25, 2001

Greetings! Anygui 0.1a3 has been released, and may be dowloaded from the anygui project page (http://sourceforge.net/projects/anygui). Anygui is a generic GUI package which allows you to write programs that will work with several backends, such as Tkinter, wxPython, PythonWin and Java Swing. The name is inspired by the standard library package anydbm, because the behaviour is similar: You write your program using the Anygui API, and Anygui figures out which back-end to use. Since the second alpha, tentative support has been added for the Model/View architecture (also called Document/View). For more information, please visit the Anygui web site at http://anygui.sf.net Magnus Lie Hetland, Anygui admin -- Magnus Lie Hetland http://hetland.org
