ANN: PSF Contribution Documents
by M.-A. Lemburg March 13, 2002

March 13, 2002

The Python Software Foundation (PSF; http://www.python.org/psf/) was created to (eventually) hold the intellectual property (IP) for the Python programming language. In order to be able to succeed in this, contributions to the Python programming language will have to be covered by legally valid contribution agreements. To make this process as simple as possible, the PSF members have come up with three different contribution agreements. The current versions of those agreements have been posted to a new mailing list at: http://mail.python.org/mailman/listinfo/psf-forms-discuss If you want to participate in the final discussion of these documents, please sign up to the list. Thank you, -- Marc-Andre Lemburg CEO eGenix.com Software GmbH ______________________________________________________________________ Company & Consulting: http://www.egenix.com/ Python Software: http://www.egenix.com/files/python/

New mailing list for Grouch
by Greg Ward Feb. 27, 2002

Feb. 27, 2002

I have just created a mailing list for general discussion of Grouch, my object schema specification and verification system for Python. (In plain terms, it's a type-checker for Python databases.) Anything Grouch-related is fair game: usage questions, bug reports, development issues, questions about the code, future plans, etc. You can join the list at http://mail.mems-exchange.org/mailman/listinfo/grouch-users The list archives (currently empty, of course) are at http://mail.mems-exchange.org/pipermail/grouch-users/ -- Greg Ward - software developer gward(a)mems-exchange.org MEMS Exchange http://www.mems-exchange.org

A mailing list for PyChecker has been created: pychecker-list(a)lists.sourceforge.net This list is meant for general discussion of PyChecker. It can also be used for general discussion of static analysis issues for python.

[ANN] JPE 2.0 The Java-Python Extension
by Frederic Giacometti Feb. 26, 2002

Feb. 26, 2002

This is the official announcement of the second version of JPE. JPE (The Java-Python Extension) is a production-grade seamless integration of Python and Java. JPE lets you call Java objects and classes from Python, and vice-versa, within the same process space. JPE is reentrant (cross-language callbacks), and supports multi-threading concurently in Java and Python. The reference web site for JPE is http://jpe.sourceforge.net As compared to its first release: 1) Build The build system of JPE is based on a new build library (libplus): - Java and python are auto-detected from the command line, and everything else is derived from there (Java libraries, library paths...). - libplus generated its own makefiles, and runtime environment (env variables) for the build and test phases; so there is no need to set-up anything - everything is now plateform-independant, and the same scripts are used on Win32 and posix (no more GNU make / cygwin make required on windows) - JPE has been ported to posix environments. However, a shared python library is required on these platforms. You can build your onw, or use the branched version of Python 2.1, named 'pythonx', which is provided for these purposes. - JPE is distributed in source form from CVS. Substantial efforts have been invested to provide a config and build environment that makes it straightforward to configure, build from source, and test multi-component, multi-platform software systems. Hopefully, that can be one step ahead from the current autoconf or distutil systems. Easily extensible to support arbitrary software components and tools, libplus currently supports C, C++, Python, Java, and swig wrappers. Libplus generates configuration-specific makefiles that chain software component dependencies together, and provides runtime software/tool configuration information. Litteratly, this is an 'open-source' project :)) 2) New capabilities of JPE, for the 2d release: - Java bean support: Jbean properties are accessed as regular python attributes - Cross-language native array access: JPE integrates the bufarray python extension type; a layer on top of the python buffer interface that provides type-safe access to contiguous fixed-length C arrays (actually, 99% of the situations in scientific C or Fortran libraries). This integration permits to safely access arrays by shared memory reference between Java, Python, and C; while hidding the native memory format. 3) Acknowledgements: Arakné, and The Molecular Graphics Laboratory at The Scripps Research Institute.

ANN: decompyle 2.2 beta 1
by Hartmut Goebel Feb. 26, 2002

Feb. 26, 2002

Announcing: decompyle -- A Python byte-code decompiler version 2.2 beta 1 'decompyle' converts Python byte-code back into equivalent Python source. It accepts byte-code from any Python version starting with 1.5 up to 2.2. The generated source is very readable: docstrings, lists, tuples and hashes get pretty-printed. 'decompyle' may also verify the equivalence of the generated source by by compiling it and comparing both byte-codes. New Features ------------ Since Release 0.6.0: * Now decompyles byte-code from Python versions 1.5 up to 2.2 * Now requires Python 2.2 but is able to decompyle older byte-coe, too. Prior version of decompyle had to be run with the Python version which generated the byte-code. * pretty-prints docstrings, hashes, lists and tuples * decompyle is now a script and a package * Now adds an emacs mode-hint and tab-width to the output files * enhanced test suite: more test patterns, .pyc/.pyo included * avoids unnecessary 'global' statements * many internal changes and code overhouls Please refere to the file 'CHANGES' for a list of changes in this release. Where to get it? ---------------- The source archives and instructions for isntalling the package can be found at: http://www.goebel-consult.de/decompyle/ Simple Help Needed! ------------------- Please help testing 'decompyle'! The EXTENDED_ARG token is untested (this is a new token for Python 2.0 which is used only if many items exist within a code object). If you have byte-code which does or may include this token, please try to decompyle your application. It's easy: the script 'test_pythonlib' which is included in the source distribution does the job for you. Just read the simple instruction there. Requirements ------------ 'decompyle' requires Python 2.2 or later. Known Bugs/Restrictions ----------------------- * The EXTENDED_ARG token is untested (this is a new token for Python 2.0 which is used only if many items exist within a code object). * Byte-code generated by Python 2.2 differs byte-code generated by a prior version even for the same source. This is due the intruduction of iterators. Currently 'Decompyle' fails verifying the source if the byte-code was generated by an older version of Python. * Verifying decompyled source with optizimzed byte code (.pyo) when running without optimizations (option '-O' not given) fails in most cases. Same is true for vis-a-versa. This is due to the fact that Python generated different bytecode depending on option '-O'. +++hartmut -- | hartmut Goebel | hartmut(a)goebel.noris.de // | | Software Manufactur | \X/ |

We plan on upgrading the mail server mail.python.org on Wednesday 27-Feb-2002, at 11am -0500 (EST, US/Eastern). This will affect all mail and mailing lists on the python.org and zope.org domains. Downtime should be minimal; if all goes well, just 10-15 minutes. You shouldn't even notice it. If you still cannot get email through by noon our time, check the www.python.org home page for status, or email Barry (barry(a)zope.com), Martijn (mj(a)zope.com), and Greg (gward(a)mems-exchange.org). -Postmaster @ {python,zope}.org
