27 Jan '00

Greetings from the Python conference! I'm pleased to announce the release of JPython 1.1 final, the 100% Pure Java implementation of the Python language. Below is a summary of recent changes. See http://www.jpython.org/NEWS for more details on what's changed. For more information on JPython in general and for links to the downloads, please see http://www.jpython.org/ Enjoy, -Barry -------------------- snip snip -------------------- 26-Jan-2000 JPython 1.1 final released - Only one small CPython compatibility patch to os.mkdir() and os.makedirs() -- optional `mode' argument, which is ignored. 21-Jan-2000 JPython 1.1 release candidate 1 released New JPython features and bug fixes - Race conditions when creating multiple PythonInterpreter objects in an embedded multithreaded Java application have been fixed. - Recursive print of a module's namespace no longer overflows the JVM stack. - Fixed backslashing of quotes inside triple quoted strings (Finn Bock). - Fixes to read(int) method on file objects, which used to return the empty string before EOF was seen. - Class-based exceptions are used in frozen (jpythonc) modules. - Duplicate argument names in a function definition raise the appropriate SyntaxError. - os.path.getsize() has been added. - mutability of tuples under some situations has been fixed. - dictionary insertion order affecting dictionary equality has been fixed (Finn Bock). - Using the --package option with jpythonc has been fixed. Improved CPython 1.5.2 compatibility - optional sizehint argument implemented for readlines() method on file objects. - Better compatibility in %g formatting of floats. - sys.stdout.softspace is now writeable. - re.VERBOSE/re.X flags are implemented. - traceback object's reprs are CPython conformant. - In module os, os.error is equivalent to the builtin OSError. Also, listdir(), mkdir(), makedirs(), remove(), rename(), and rmdir() raise OSError directly. - os.stat() raises an OSError if the file is missing. <A HREF="http://www.jpython.org">JPython 1.1 final</A> - a 100% Pure Java implementation of the Python language.

f2py 1.116: The Fortran to Python Interface Generator
by Pearu Peterson 25 Jan '00

25 Jan '00

I am pleased to announce the first public release of f2py 1.116: Writing Python C/API wrappers for Fortran routines can be a very tedious task, especially if a Fortran routine takes more than 20 arguments but only few of them are relevant for the problems that they solve. The Fortran to Python Interface Generator, or FPIG for short, is a command line tool (f2py) for generating Python C/API modules for wrapping Fortran 77 routines, accessing common blocks from Python, and calling Python functions from Fortran (call-backs). The tool can be downloaded from http://cens.ioc.ee/projects/f2py2e/ where you can find also information about f2py features and its User's Guide. f2py is released under the LGPL license. With regards, Pearu Peterson <pearu(a)ioc.ee> <A HREF="http://cens.ioc.ee/projects/f2py2e/">f2py 1.116</A> - The Fortran to Python Interface Generator.

by Michael Ströder 25 Jan '00

25 Jan '00

HI! I would like to announce a new version of web2ldap, a full-featured LDAPv2 client written in Python designed to run as a CGI-BIN under the control of a WWW server. It's available for free (GPL) from http://www.web2ldap.de/ There's a demo running on: http://sites.inka.de/ms/cgi-bin/web2ldap.py I would like to encourage people to give feedback about the usability of this program. Ciao, Michael. Changes since 0.6.5: - You might have guessed it: Bug hunting and code cleaning! - Better support and example for CSS Changes since 0.6.4: - Implemented modrdn. - Omnipresent button bar throughout the whole UI now (including error messages). - Direct input of LDIF data possible during adding or modifying entries (e.g. for binary data). - Display attributes of entry according to the schema categories (required, allowed, not matching). - Minor bugfixing and code cleaning. Finally you insert your blinky-winky HTML design: - Display entries with HTML template files depending on objectClass. - HTML clean-up to be hopefully SGML-conformant (and friendly to browsers). - Configuration parameters for complete <BODY> tag. - ID params in important HTML tags for using CSS. - Configuration parameters for string placed in <HEAD></HEAD> section (suitable for placing <STYLE> tags). <A HREF="http://www.web2ldap.de/">web2ldap 0.6.6</A> - web-based LDAP client; several enhancements.

platform.py - Version 0.7.0
by M.-A. Lemburg 25 Jan '00

25 Jan '00

ANNOUNCING: platform.py - Version 0.7.0 A Python module providing platform information APIs. WHAT IT IS: platform.py was intially developed for the mxCGIPython project to automate the creation of file names including platform specific data for users to be able to recognize and download the appropriate Python interpreter binary for their (or their ISPs) setup. Since then the module has been extended and redesigned to provide a generic interface for querying platform information both in human readable form and for other application purposes through platform dependent special APIs. platform.py supports (at least) these setups: most Windows setups, MacOS, various Linux distributions, various Unices, OpenVMS, Java VM and DOS. WHAT'S NEW ? Version 0.7.0 is the first new version after the intial release and update cycles last year. WHERE CAN I GET IT ? Documentation is provided through doc-strings and many comments in the source code, which can be found via my Python Pages: http://www.lemburg.com/~python/ WHAT DOES IT COST ? It comes with a Python-style license, but is otherwise free for commercial and non-commercial use. WHERE CAN I GET SUPPORT ? Commercial support for all my packages, tools and other Python software will soon be available through my newly founded software company. Keep an eye open on this list for an announcement. REFERENCE: <A HREF="http://www.lemburg.com/~python/">platform.py 0.7.0</A> - generic platform information APIs.

Python Conference weather
by Guido van Rossum 25 Jan '00

25 Jan '00

If you're traveling to the Python Conference, be advised that winter has finally arrived in the Washington, DC area. We're currently experiencing *high* temperatures of 22 degrees F (-6 degrees C); with the wind chill it will feel much colder. So be sure to pack warm clothes. Yesterday, about 6 inches of snow fell, disrupting air travel; more is expected on Sunday, so expect delays flying into DC. Local transportation should be fully operational, but may experience some delays. We've placed a weather advisory in the local section of the conference website: http://www.python.org/workshops/2000-01/local.html Over 250 people have registered for the conference. See you all there! --Guido van Rossum (home page: http://www.python.org/~guido/) -- ----------- comp.lang.python.announce (moderated) ---------- Article Submission Address: python-announce(a)python.org Python Language Home Page: http://www.python.org/ Python Quick Help Index: http://www.python.org/Help.html ------------------------------------------------------------

Stackless Python 1.0 + Continuations 0.6
by Christian Tismer 21 Jan '00

21 Jan '00

ANNOUNCING: Stackless Python 1.0 A Python Implementation That Does Not Use The C Stack * plus the real toy * Continuation Module 0.6 Continuations as First Class Objects What is it? A plugin-replacement for core Python. It should run any program which runs under Python 1.5.2 . But it does not need space on the C stack. Why did I write it? Stackless Python was never written before (afaik), since it was said to be impossible without major rewrites of core Python. I have proven the controverse: It is easy to write, just hard to think. About 3 times harder was finally the continuation module. The whole project took about 6 man months where 80 percent of the time was thinking and trying. The rest was coding and to become a reference counting champion :-) Recent changes: Version 1.0 has been optimized like hell and is now 3-5 percent faster than Standard Python. Continuation module is in version 0.6, very stable, and it allows to save a program's "future" at any time, in a portable way. Continuations are callable Python objects with a very small footprint. Who needs it? Since the continuations are done, this is no more only useful for C programmers who want to try certain new ideas. Everybody who is interested to develop his own generators, coroutines and tiny threads is invited to check it out. Status of the final 1.0: Pystone works correctly and is 5% faster than standard Python. Version 0.3 was 10 percent slower. Continuations work with PythonWin and Idle. The overall result is now better than expected, and I'm happy to call this *FINAL* (until the next version of course:) Downloadable files can be found at http://www.tismer.com/research/stackless/ Some older documentation: http://www.tismer.com/research/stackless/stackless.htm Some better documentation can be found in my IPC8 paper: http://www.tismer.com/research/stackless/spc_final.zip or be read directly as HTML http://www.tismer.com/research/stackless/spcpaper.htm Source code and a VC++6.0 build for Windows (340K): http://www.tismer.com/research/stackless/spc_win32.zip cheers - chris == Christian Tismer :^) <mailto:tismer@appliedbiometrics.com> Applied Biometrics GmbH : Have a break!
