I have released a minor update to Plex, a lexical analysis module for Python: http://www.cosc.canterbury.ac.nz/~greg/python/Plex/ The yield() method of the Scanner class has been renamed to produce() for compatibility with Python 2.2 and later. (The old name is still available when running under 2.1 or earlier, or under 2.2 when generators are not being used.) I have also changed one of the tests slightly so that it doesn't get confused by recent changes in the way repr() displays strings containing unprintable characters. -- Greg Ewing, Computer Science Dept, University of Canterbury, Christchurch, New Zealand To get my email address, please visit my web page: http://www.cosc.canterbury.ac.nz/~greg

ANN: Pyrex 0.1.1

by Greg Ewing

I have fixed a few bugs in Pyrex and made it available as version 0.1.1: http://www.cosc.canterbury.ac.nz/~greg/python/Pyrex/ While you're there, pick up the latest version of Plex too (1.1.2), which doesn't use yield as a method name any more. Fixes in this version: * Bogus re-use of temp variables shouldn't happen now. * Access to builtin names now works. * Exceptions should work now (in simple cases, anyway). * Conditions in if-statements now evaluated correctly. More bug fixes are in the works. Thanks to all who have provided feedback so far -- keep it coming! -- Greg Ewing, Computer Science Dept, University of Canterbury, Christchurch, New Zealand To get my email address, please visit my web page: http://www.cosc.canterbury.ac.nz/~greg

ANN: disipyl - a 2D and 3D Python and Jython plotting library

by Paul Magwene

DESCRIPTION: ----------- disipyl is an object-oriented wrapper around the DISLIN plotting library. DISLIN is a powerful and flexible multiplatform (Win32, Unix, Linux, etc.) library designed for displaying scientific data. DISLIN's author, Helmut Michels, has made available a DISLIN plotting extension for the Python programming language (see http://www.linmpi.mpg.de/dislin/ for more details). disipyl provides a set of classes which represent various aspects of DISLIN plots, as well as providing some easy to use classes for creating commonly used plot formats (e.g. scatter plots, histograms, 3-D surface plots). A major goal in designing the library was to facilitate interactive data exploration and plot creation. Documentation, a tutorial, and a demo program are included. The library has been tested on Win32, Linux, and FreeBSD, but I anticipate that it should work on any platform which can make use of Python, NumPy, and the DISLIN python extensions. Feedback, comments, and critique are gladly accepted (email: paul.magwene(a)yale.edu). VERSION: ------- This is release 0.6 of disipyl. CHANGES: ------- New in this release: * support for plot interaction (record plot coordinates via mouse clicks) * new mechanism for quering disipyl objects about the options they support * cleanup of data/option setting mechanisms for disiypl objects * Jython support (when DISLIN java library available - most but not all classes) * updated documentation and tutorial URL: ---- You can find disipyl at: http://pantheon.yale.edu/~pmm34/disipyl.html

Quick followup: I just released version 2.0.1 which fixes a few problems in the test suite. There's also one minor API change that syncs this version with the version that's now in the Python 2.3 cvs tree. It is recommended that you grab the 2.0.1 version, but it's not urgent. -Barry

RELEASED: Python 2.2.1

by Michael Hudson

We've released a bugfix release of Python, 2.2.1! This release should be fully compatible with Python 2.2. Everyone using 2.2 is recommended to upgrade to 2.2.1. On the 2.2.1 pages http://www.python.org/2.2.1/ you can find more information, binaries for Windows, Redhat 7.2 & 6.2, Mandrake 8.2 and MacOS 8, 9 & X, as well as the usual tarball. Thanks are due to those who provided the binaries and to all who tested the prerelases during the 2.2.1 release process! One nasty bug (that affected Zope in obscure circumstances) and a few less serious ones have been fixed since the second release candidate. Two fixes may be of special interest if you use MacOS X: - This release finally works on Mac OS X multiprocessors - The IDE is now fully functional on Mac OS X. This being a bugfix release, there are no exciting new features -- we just fixed a lot of bugs. For a moderately complete list, please see: http://www.python.org/2.2.1/NEWS.txt Cheers, The Python development team.

What: BayPIGgies meeting When: Wed, 10 Apr 2002, 7:30-9 PM Where: Stanford University, Palo Alto, CA Agenda: Newbies Night Speaker: everyone... Invite everyone you know who may be interested in Python but have questions, would like to learn more about it, or need some advice on an application! These meetings have been very popular in the past, with a good mix of newbies as well as old hands. They are even more fun when one or more Perl experts come around wondering what the big deal is about Python. :-) Come join us for this interactive session! Next Meeting (5/8): Eating Out with Python (our meeting room will not be available, so we will meet and chat over dinner at a local restaurant!) -------------------------------------------------------------------------------- Call For Talks: We are actively seeking speakers for BayPIGgies!

RELEASED: Python 2.1.3

by Guido van Rossum

Today, April 8th 2002, we've released Python 2.1.3, the latest version of Python 2.1. This is not the latest and greatest release, but is for people who want or need to run Python 2.1. Anthony Baxter was the 2.1.3 releasemeister, for which I thank him profusely. Great job, Anthony! The new release is available here: http://www.python.org/2.1.3/ (Note that we no longer release files via SourceForge -- it's a bit of a hassle, and few people seem to download their files from there.) This release has a small number of critical bug fixes that have come up since 2.1.2 was released, in particular one bug that caused Zope to crash under certain obscure circumstances. What's New in Python 2.1.3? --------------------------- Core - Fixed two bugs reported as SF #535905: under certain conditions, deallocating a deeply nested structure could cause a segfault in the garbage collector, due to interaction with the "trashcan" code; access to the current frame during destruction of a local variable could access a pointer to freed memory. - SF #457466: popenx() argument mangling hangs python (win9x only). Under certain circumstances, using any of the popen calls on win9x would cause python to hang. Library - The xml.sax.expatreader.ExpatParser class will no longer create circular references by using itself as the locator that gets passed to the content handler implementation. [SF bug #535474] - A security hole ("double free") was found in zlib-1.1.3, a popular third party compression library used by some Python modules. The hole was quickly plugged in zlib-1.1.4, and the Windows build of Python now ships with zlib-1.1.4. Windows - The installer now installs Start menu shortcuts under (the local equivalent of) "All Users" when doing an Admin install. - If you do what it takes to compile SSL support for Windows, a bug in httplib.py prevented SSL from working correctly. That bug has been fixed, but note that SSL support on Windows is still not enabled in this release. --Guido van Rossum (home page: http://www.python.org/~guido/)

RELEASED email 2.0 (standalone)

by barry＠zope.com

I've just released version 2.0 of the standalone email package. This will likely be the last official standalone release, as I intend to complete the merge of the package into the Python 2.3 cvs tree. The email package is a library for managing email messages, including MIME and other RFC 2822-based message documents. It subsumes most of the functionality in several older standard modules such as rfc822, mimetools, multifile, and other non-standard packages such as mimecntl. The email package is compatible with both Python 2.1 and Python 2.2. Online documentation is available at http://www.python.org/doc/current/lib/module-email.html although this does not yet cover the new features in email 2.0. You can download the lastest version from http://sourceforge.net/project/showfiles.php?group_id=25568 Enjoy, -Barry

Scheduled maintenance for all mail at python.org & zope.og

by barry＠zope.com

We plan on doing another upgrade to the mail server mail.python.org, a.k.a. lists.zope.org on Wednesday 10-Apr-2002, at 11am -0400 (EDT, US/Eastern). We will be upgrading to Exim 4, and 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 15-30 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

ID3.py Version 1.2 Released!

by Ben Gertzfield

I've released version 1.2 of ID3.py, the simple ID3v1 MP3 tag reader/manipulator class for Python. This version includes an exciting new dictionary-based interface, compatible with the ogg.vorbis class, to read all ID3 tags at once. Also, the default genre when creating an ID3 tag has been changed from 0 ("Blues") to 255 ("Unknown"). ID3.py is hosted by SourceForge. Its home page is: http://id3-py.sourceforge.net/ You can always download the latest release of ID3.py from: http://id3-py.sourceforge.net/id3-py.tar.gz There are already Debian GNU/Linux packages available in the unstable distribution. Happy MP3 hacking! Ben Gertzfield
