Perhaps a rather quick Py2.4.1 would be in order. Ideally, it should include other important fixes: * Tim's critical thread bug http://www.python.org/sf/1069160 * Compile of _socket fails on 2.4 (SGI Orion only) http://www.python.org/sf/1086642 (waiting for a developer who has this set-up) * sys.stdin segfaults on invalid stdin http://www.python.org/sf/1084766 (Jeff Epler has already isolated the problem) * truncated gzip file triggers zlibmodule segfault http://www.python.org/sf/1083110 (assigned to Andrew) * various installer issues (all currently assigned to Martin) * bad arg type to isspace in struct module http://www.python.org/sf/1072182 (assigned to me) * fix bug in StringIO.truncate - length not changed http://www.python.org/sf/951915 (assigned to me) * Fix for off-by-one bug in urllib.URLopener.retrieve http://www.python.org/sf/810023 (assigned to me) Raymond

PyCon is coming - we need your help
by Steve Holden Dec. 21, 2004

Dec. 21, 2004

Dear Python User: I wonder if you would be kind enough to take the time to read this email and help us to publicize PyCon DC 2005, being held March 23-26 at the Cafritz Conference Center of George Washington University. The Call for Participation went out some time ago, but it is a good time to remind people that the deadline for submissions is December 31. If you personally are thinking of submitting a paper then this can be a reminder to do so soon! We already have acceptances from two keynote speakers, and hope to announce them when a third is finalised shortly. As always you can find out about the conference at http://www.pycon.org/ http://www.python.org/pycon/ This year we are going to be able to accept credit card payments for the first time, which we hope will be more convenient for delegates. The registration fees this year are the same as for 2004: Early Bird (to Jan 22) $175 ($125 student) Regular (to Mar 19) $250 ($175 student) On-Site $300 ($225 student) A further announcment will be made when the registration site opens for business. In the meantime I would appreciate your assistance in posting this message via any channels you know of that have an interest in the Python language and its applications - publicity is the key to getting the most diverse group of people at PyCon. regards Steve Holden Chairman, PyCON DC 2005 -- PyCon DC 2005: The third Python Community Conference http://www.pycon.org/ http://www.python.org/pycon/ The scoop on Python implementations and applications

Py2.4 _sre uses uninitialised memory (Bug 1088891)
by Andrew McNamara Dec. 21, 2004

Dec. 21, 2004

_sre.c, data_stack_grow() in Py2.4 uses realloc()'ed memory without initialising the newly allocated memory. For complex regexps that require additional sre stack space, this ultimately results in a core dump or corrupted heap. Filling the newly allocated memory with 0x55 makes the problem more obvious (dies on a reference to 0x55555558) for me. See bug ID 1088891: http://sourceforge.net/tracker/index.php?func=detail&aid=1088891&group_id=5… Can I be the only person who crafts diabolical regexps? Here, have a lend of my brown paper bag... -- Andrew McNamara, Senior Developer, Object Craft http://www.object-craft.com.au/

Which means that there is no way in 2.4.0 to marshal an object in the old version format as a string -- you'd have to work around by writing a real file and reading it back :-( Armin

MS VC compiler versions
by M.-A. Lemburg Dec. 19, 2004

Dec. 19, 2004

Preparing for the distutils patch to allow building extensions using the .NET SDK compilers, I am compiling a list of version numbers and MS compiler logo outputs in order to use these to identify the correct compiler to use for the extensions. These are the compilers I have found so far: * MS VC6 (German version; optimizing VC6 compiler): Optimierender Microsoft (R) 32-Bit C/C++-Compiler, Version 12.00.8804, fuer x86 Copyright (C) Microsoft Corp 1984-1998. Alle Rechte vorbehalten. * MS .NET SDK 1.1 Compiler (German version; non-optimizing VC7.1 compiler): Microsoft (R) 32-Bit C/C++-Standardcompiler Version 13.10.3077 für 80x86 Copyright (C) Microsoft Corporation 1984-2002. Alle Rechte vorbehalten. * MS VC7.1 (aka .NET 2003, US version; optimizing VC7.1 compiler) Microsoft (R) 32-bit C/C++ Optimizing Compiler Version 13.10.3077 for 80x86 Copyright (C) Microsoft Corporation 1984-2002. All rights reserved. [It looks as if optimizing vs. non-optimizing is not something that you can detect by looking at the version number.] Could you please provide me with more version numbers and logo printouts ?

mmap feature or bug?
by Josiah Carlson Dec. 19, 2004

Dec. 19, 2004

Quick questions: Is mmap's inability to be subclassed a feature or bug? Is one's inability to use a = mmapinstance.__setslice__;a(1,2,'a') (and others) a feature or bug? I would imagine they are bugs, but I just wanted to make sure and post the report/request in the proper location. Thank you, - Josiah

Python in education
by Randy Chung Dec. 19, 2004

Dec. 19, 2004

Hi everyone, I'm going to be leading a class on Python at the University of California, Berkeley next semester (starting in January). I'm interested in using actual bugs in Python as exercises for the class, the goal being 1) to give the students something "real" to work with, and 2) to (hopefully) contribute back anything we manage to put together to the Python dev team. What I'm looking for are some oustanding bugs which the more experienced devs feel would be straightforward to implement (which might not have been implemented yet because they're not very interesting, or there are simply too many other things to do right now). I'd appreciate any and all suggestions any of you might be able to provide. I think that Python will have a better chance at wider adoption if universities would provide courses for the language. I'm running this class partly because I'd like to give back to the community which produced a language I've enjoyed using, and any assistance would be greatly appreciated. If you feel this is off topic, please feel free to reply to me off-list. Thanks, Randy Chung
