Mailman 3 April 2002 - Python-announce-list

Personal python webmail
by Adam Hixson 25 Apr '02

25 Apr '02

I'd like to announce the release of a new, simple program to allow individuals the joy that is webmail. Requiring python 2.2, openssl, the m2crypto module and a pop client that can deposit mail into /var/mail unix-like files ppwm v0.0.4.1.0 will serve email over a secured http connection. It can handle MIME attachments as well. Give it a try.

[ANN] ClientCookie: HTTP cookie handling on client end
by John J. Lee 25 Apr '02

25 Apr '02

ClientCookie 0.02a http://wwwsearch.sourceforge.net/README-ClientCookie http://wwwsearch.sourceforge.net/ClientCookie-0.02a.tar.gz or http://wwwsearch.sourceforge.net/ClientCookie-002a.zip WARNING: this is an alpha release: interfaces may change (probably not, though). Since this is a port rather than completely new code though, it does actually seem to work quite well! Also note that redirects are not handled correctly yet when used with the extended urllib2 callables (urlopen, HTTPHandler, etc): they'll probably accept and send cookies when they shouldn't in some cases. This is a Python port of Gisle Aas' HTTP::Cookies Perl module from the libwww-perl web client library. The purpose of this Python package is to allow the easy extraction of HTTP cookies from "Set-Cookie" and "Set-Cookie2" (RFC 2965) headers, and generation of "Cookie" and "Cookie2" headers appropriate for a particular HTTP request. Incoming cookies are checked for acceptability based on the host name, etc. Cookies are only set on outgoing requests if they match the request's host name, path, etc. Python 2.0 or above is required (though I may fix it to work with 1.52 eventually), and urllib2 is recommended. Note that the version of urllib2.py from Python 2.0 is too old: you need the version from Python 2.1 (available from the source distribution or CVS from http://www.python.org), which itself depends on inspect.py -- just copy them into your Python search path. import ClientCookie import urllib2 request = urllib2.Request("http://www.acme.com/") # note we're using the urlopen from ClientCookie, not urllib2 result = ClientCookie.urlopen(request) # let's say this next request requires a cookie that was set in result request2 = urllib2.Request("http://www.acme.com/flying_machines.html") result2 = ClientCookie.urlopen(request) (lower-level usage is also possible) Distrubuted under the Perl Artistic License.

Stackless goes Limbo
by Christian Tismer 24 Apr '02

24 Apr '02

Hi all, after some time of consideration, I have decided to move the interface to Stackless Python's multitasking towards the ideas behind the Limbo Language. Besides the tasklets, there are "channel" objects, which allow for communication between tasklets. This approach is simple and powerful. Blocking of tasklets takes place on writes when no tasklet is listening, or on reads, when no data is available. There is some nice introduction to Limbo at http://www.vitanuova.com/inferno/papers/descent.html written by Brian W. Kernighan, one of the inventors of the C language. I hope to have a prototype ready by end of April.

[ANN] Py Subscriptions
by cook＠pyzine.com 23 Apr '02

23 Apr '02

El Segundo, CA - 2002 April 23 - Py Parlour Press announced today that subscriptions for Py, an independent print zine for Python developers, were now available. "The idea of being shackled to this zine for the next year of my life apparently appeals to some deep masochistic subconscious yearning I am unaware of in my waking hours" said Bryan Richard, editor and publisher. The cost for a Domestic subscription is US$10.00 and US$15.00 for all orders outside the United States. A single subscription is for four (4) issues of Py. "Subscriptions were by far the most frequent request received, right after a media type that didn't disintegrate when exposed to sunlight." Pythonistas can subscribe online at www.PyZine.com. In other news, PyZine.com just went through a massive facelift, making it an almost usable website. A couple of new features were added (the Py-O-Meter which carries a running total of zines sold) and the FAQ was given a serious throttling. About Py It's a print zine. About Python. Get hip to that. About Py Parlour Press (the multinational media conglomerate) Py Parlour Press is a guy named Bryan Richard and the saints that contribute articles (who spare you, the reader, from Bryan's writing). Bryan is a book nerd, drives a beat blue Volvo, and listens to way too much Songs:Ohia, which contains way too many E minor chords. With the addition of subscriptions Bryan should be ensconced in Hearst Castle before the year is out.

Python Cryptograph Toolkit 1.9alpha1
by Andrew Kuchling 23 Apr '02

23 Apr '02

I've wrapped up a new, alpha-quality, release of the Python Cryptography Toolkit. It's not backward-compatible with earlier releases, in an effort to fix the design errors I've made in the past. Dodgy algorithms have been dropped, and one new one, AES, has been added. The public-key code is also gone. A list of the changes in this version: * Added Crypto.Cipher.AES. * Added the CTR mode and the variable-sized CFB mode from the NIST standard on feedback modes. * Removed Diamond, HAVAL, MD5, Sapphire, SHA, and Skipjack. MD5 and SHA are included with Python; the others are all of marginal usefulness in the real world. * Renamed the module-level constants ECB, CFB, &c., to MODE_ECB, MODE_CFB, as part of making the block encryption modules compliant with PEP 272. (I'm not sure about this change; if enough users complain about it, I might back it out.) * Made the hashing modules compliant with PEP 247 (not backward compatible -- the major changes are that the constructor is now MD2.new and not MD2.MD2, and the size of the digest is now given as 'digest_size', not 'digestsize'. * The Crypto.PublicKey package is no longer installed; the interfaces are all wrong, and I have no idea what the right interfaces should be. See the TODO file for a list of other fixes I'd like to make before finalizing this as version 2.0. CVS is available through the pycrypto project on SourceForge. The source code is available at http://www.amk.ca/files/python/pycrypto-1.9a1.tar.gz . -- A.M. Kuchling http://www.amk.ca run-time. n. (QA testing) the moment when the programmer shouts "Must run!" and disappears. -- Stan Kelly-Bootle, _The Computer Contradictionary_

ANN: Python Computer Graphics Kit v1.0beta2
by Matthias Baas 21 Apr '02

21 Apr '02

The second beta release of the Python Computer Graphics Kit is available at http://cgkit.sourceforge.net What is it? ----------- The kit is a collection of Python modules that contain the basic types and functions required for creating 3D computer graphics images. The kit includes several new types such as vectors, matrices and quaternions. It contains a binding for Pixar's RenderMan interface which is a renderer independent API to communicate 3D data to renderers which will finally produce a 2D image. There are already several RenderMan compliant renderers freely available (they are not part of the kit). The kit also includes some of the functionality from the RenderMan Shading Language which enables you to create procedural models or textures from within Python. Even though the kit focuses on RenderMan, the new types or the Shading Language functionality can also be used for other rendering mechanism such as OpenGL or other renderers such as POV-Ray. The kit should run on any platform where Python (and a C/C++ compiler) is available. Windows users can download a binary version for Python 2.1 or Python2.2. What's new? ----------- The noise module is far more complete than before. In addition to the normal noise function there's a periodic noise function and a cellnoise function which is constant between integer points. All functions also have a vector version that return a vector instead of a single float. There has also been a small bugfix in the RenderMan binding concerning CSG, and a few other minor modifications (see the changelog). The kit should also compile under Linux now (the noise module couldn't be imported in the previous version). For more information, visit: http://cgkit.sourceforge.net - Matthias -
