ANN: Pyro 2.2 is available
by Irmen de Jong Nov. 30, 2001

Nov. 30, 2001

You can get the latest Pyro version (2.2) at http://pyro.sourceforge.net What is Pyro? Pyro is an acronym for PYthon Remote Objects. It is a basic Distributed Object Technology system written entirely in Python. It is extremely easy to implement a distributed system with Pyro, because all network communication code is abstracted and hidden from your application. You just get a remote Python object and invoke methods on the object on the other machine. Pyro offers you a Name Server, an Event Service, mobile objects, remote exceptions, dynamic proxies, remote attribute access, automatic reconnection, a detailed manual, and many examples to get you started right away.

mimedecode.py version 1.1.1
by Oleg Broytmann Nov. 29, 2001

Nov. 29, 2001

Hello! mimedecode.py WHAT IS IT Mail users, especially in non-English countries, often find that mail messages arrived in different formats, with different content types, in different encodings and charsets. Usually this is very good because it allows us to use apropriate formats/encodings/whatever. Sometimes, though, some unification is desireable. For example, one may want to put mail messages into an archive, make HTML indicies, run search indexer, etc. In such situations converting messages to text in one character set and skipping some binary atachmetnts will be much desireable. Here is the solution - mimedecode.py. This is a program to decode MIME messages. The program expects one input file (either on command line or on stdin) which treated as an RFC822 mesage, and decoded to stdout. If the file is not an RFC822 message the file just piped to stdout one-to-one. If it is a simple RFC822 message it is just decoded as one part. If it is a MIME message with multiple parts ("attachments") all parts decoded. Decoding can be controlled by command-line options. WHAT'S NEW in version 1.1.1 Documentation in DocBook v4.1 format. HTML, plain text and manual page.

ANNOUNCE: Optik 1.1.1
by Greg Ward Nov. 28, 2001

Nov. 28, 2001

Optik 1.1.1 =========== Optik is a powerful, flexible, extensible, easy-to-use command-line parsing library for Python. Using Optik, you can add intelligent, sophisticated handling of command-line options to your scripts with very little overhead. Here's an example of using Optik to add some command-line options to a simple script: from optik import OptionParser [...] parser = OptionParser() parser.add_option("-f", "--file", action="store", type="string", dest="filename", help="write report to FILE", metavar="FILE") parser.add_option("-q", "--quiet", action="store_false", dest="verbose", default=1, help="don't print status messages to stdout") (options, args) = parser.parse_args() With these few lines of code, users of your script can now do the "usual thing" on the command-line: <yourscript> -f outfile --quiet <yourscript> -qfoutfile <yourscript> --file=outfile -q <yourscript> --quiet --file outfile (All of these result in options.filename == "outfile" options.verbose == 0 ...just as you might expect.) Even niftier, users can run one of <yourscript> -h <yourscript> --help and Optik will print out a brief summary of your script's optons: usage: <yourscript> [options] options: -h, --help show this help message and exit -fFILE, --file=FILE write report to FILE -q, --quiet don't print status messages to stdout That's just a taste of the flexibility Optik gives you in parsing your command-line. See the documentation included in the package for details. AUTHOR, COPYRIGHT, AVAILABILITY ------------------------------- Optik was written by Greg Ward <gward(a)python.net> The latest version of Optik can be found at http://optik.sourceforge.net/ Copyright (c) 2001 Gregory P. Ward. All rights reserved. CHANGES IN OPTIK 1.1.1 ---------------------- * Various documentation tweaks (thanks to Alan Eldridge <alane(a)geeksrus.net> for prodding me into those, and for doing most of one). * Fixed a bug that prevented users from doing things like -f"" or --file="" on the command-line. Involved rewriting some hairy code in OptionParser, which has the pleasant side-effect that the first argument to an option with multiple arguments can now be jammed up against the option, eg. "-p3 5 1". -- Greg Ward - geek-at-large gward(a)python.net http://starship.python.net/~gward/ Very few profundities can be expressed in less than 80 characters.

Nov. 28, 2001

I've just released version 2.0.8 of Mailman, the GNU Mailing List Manager. Mailman is released under the GNU General Public License (GPL). Version 2.0.8 closes several cross-site scripting vulnerabilities and includes a few other minor bug fixes. More information on cross-site scripting exploits in general can be found at http://www.cert.org/advisories/CA-2000-02.html I recommend anybody running a version of Mailman up to, and including 2.0.7 to upgrade to version 2.0.8. GNU Mailman is software to help manage electronic mail discussion lists. Mailman gives each mailing list a unique web page and allows users to subscribe, unsubscribe, and change their account options over the web. Even the list manager can administer his or her list entirely via the web. Mailman has most of the features that people want in a mailing list management system, including built-in archiving, mail-to-news gateways, spam filters, bounce detection, digest delivery, and so on. Mailman is compatible with most web servers, web browsers, and mail servers. It runs on GNU/Linux and should run on any other Unix-like operating system. Mailman 2.0.8 requires Python 1.5.2 or newer. To install Mailman from source, you will need a C compiler. For more information on Mailman, including links to file downloads, please see the Mailman web page: http://www.gnu.org/software/mailman And its mirrors at: http://mailman.sourceforge.net http://www.list.org (Note: the gnu.org mirror is not yet updated.) Patches and tarbals are available at http://sourceforge.net/project/showfiles.php?group_id=103 There are email lists (managed by Mailman, of course!) for both Mailman users and developers. See the web sites above for details. Cheers, -Barry -------------------- snip snip -------------------- 2.0.8 (27-Nov-2001) Security fix release to prevent cross-site scripting exploits.

PySomorph 0.91 Graph Isomorphism Library
by Brian Kelley Nov. 27, 2001

Nov. 27, 2001

PySomorph is a python package for investingating subgraph isomorphism. Subgraph Isomorphism is useful for a number of pratical applications spanning from relational theory to investigating chemical structures. PySomorph is a binding to the University of Napoli's <http://amalfi.dis.unina.it/graph/> graph isomorphism library. The main benefit is that edges and nodes of graph structures can be arbitrary python objects. This allows for an amazing amount of flexibility in the creation and searching of various graphs. * Now uses disutils for unix/linux installations. * Fixed a reference counting bug that caused odd failures when certain objects were deleted. * added an example application, subgraph isomorphism for network topology Download and homepage at http://staffa.wi.mit.edu/people/kelley/ Brian Kelley Whitehead Institute for Biomedical Research

ANN Installer Release 5
by gmcm＠hypernet.com Nov. 27, 2001

Nov. 27, 2001

Release 5 of the McMillan Installer is here: http://www.mcmillan-inc.com/install5_ann.html Release 5 is a rewrite of the analysis and building code from earlier releasess. The result is much smaller, faster and more capable. Major changes include: - Instead of using an ini-file configuration (with a host of confusing options), Release 5 uses Python syntax specification files. - An extensible hooks mechanism for modules / packages that use import hacks. - Ability to run on non-ELF platforms (should run on most Unix systems, although I have not been able to test much of this). - Linux users get full binary dependency analysis (so you can include a private installation of TCL/TK or wxWindows, for example). - Windows users can now create "frozen" in-process COM servers. - Refactored C code (many thanks to Alan Green) so embedders can make use of Installer's capabilities. There is also an Installer mailling list. Subscribe at: http://trixie.triqs.com/mailman/listinfo/installer Supported systems include: - Windows - Linux - Unix (alpha quality) Supported Python versions: - Python 1.5 to 2.1 (2.2b2 appears to work too). What is it: The Installer package is any easy way to deploy Python apps to systems without Python installed (or with incompatible Pythons installed). License: MIT style. Contact: gmcm(a)hypernet.com <P><A HREF="http://www.mcmillan-inc.com/install5_ann.html">Installer Release 5</A>Easy Python app deployment. (27-Nov-2001).

pyrepl-0.6
by Michael Hudson Nov. 27, 2001

Nov. 27, 2001

I'm pleased to announce a new version of my pyrepl package. Here's an excerpt from the README: This is pyrepl 0.6, a readline-a-like for Python, which seems to be being released on 2001-11-27. http://starship.python.net/crew/mwh/hacks/pyrepl.html It requires python 2.1 (or newer) with the curses and termios modules built, and features (in less than 3000 lines of code): * sane multi-line editing * history, with incremental search * completion, including displaying of available options * a fairly large subset of the readline emacs-mode keybindings (adding more is mostly just a matter of typing) * a liberal, Python-style, license * a new python top-level * no global variables, so you can run two or more independent readers without having their histories interfering. * generally speaking, a much more interactive experience than readline (it's a bit like a cross between readline and emacs's mini-buffer) [...] Please direct comments to mwh(a)python.net. (If you've released open source software you'll know how frustrating it is to see a couple of hundred downloads and only get a handful of emails, so don't think I'll be irritated by the banality of your comments!) New since 0.5.1: + Rewrote the low level code to be (hopefully) more portable and (certainly) clearer. Most of the code from 0.5.1 is still present, but it's been moved around and refactored (and the names have gotten more sensible). + The above process fixed a fair few bugs. + Implemented a few more emacs-mode bindings. + Nailed another couple of differences between my top-level and the the default one, including playing nice with Tk. + Implemented a saner way of handling window resizes (a sane way of handling signals! Call the Unix police!) + minimal testing on cygwin. [...] Cheers, M. -- 3. Syntactic sugar causes cancer of the semicolon. -- Alan Perlis, http://www.cs.yale.edu/homes/perlis-alan/quotes.html

ANN: Python Benchmark Suite -- pybench 1.0
by M.-A. Lemburg Nov. 26, 2001

Nov. 26, 2001

________________________________________________________________________ ANNOUNCING: pybench -- The Python Benchmark Suite Version 1.0.0 Extendable suite of of low-level benchmarks for measuring the performance of the Python implementation (interpreter, compiler or VM). ________________________________________________________________________ WHAT IS IT ?: pybench is a collection of tests that provides a standardized way to measure the performance of Python implementations. It takes a very close look at different aspects of Python programs and let's you decide which factors are more important to you than others, rather than wrapping everything up in one number, like the other performance tests do (e.g. pystone which is included in the Python Standard Library). pybench has been used in the past by several Python developers to track down performance bottlenecks or to demonstrate the impact of optimizations and new features in Python. There's currently no documentation and no distutils support in pybench; that'll go into one of the next releases. For now, please read the source code. The command line interface for pybench is the file pybench.py. Run this script with option '--help' to get a listing of the possible options. Without options, pybench will simply execute the benchmark and then print out a report to stdout. Here's some sample output: """ Tests: per run per oper. overhead ---------------------------------------------------------------------- BuiltinFunctionCalls: 131.50 ms 1.03 us 0.50 ms BuiltinMethodLookup: 195.85 ms 0.37 us 1.00 ms CompareFloats: 126.00 ms 0.28 us 1.00 ms CompareFloatsIntegers: 201.05 ms 0.45 us 0.50 ms CompareIntegers: 192.05 ms 0.21 us 2.00 ms CompareInternedStrings: 117.65 ms 0.24 us 3.50 ms ...

This release includes a few more tests and extends the range of supported Python versions to 1.5.x - 2.2. It is also the first publically announced new version of pybench in years. ________________________________________________________________________ WHERE CAN I GET IT ? The download archive of the package can be found at: http://www.lemburg.com/files/python/ ________________________________________________________________________ WHAT DOES IT COST ? pybench comes with a Python style license, which means that you can use them in both commercial and non-commercial settings without fee or charge. It comes with full source code. ________________________________________________________________________ WHERE CAN I GET SUPPORT ? Commercial quality support for this package is available from eGenix.com Software GmbH in form of support tickets. Please see http://www.lemburg.com/files/python/eGenix-mx-Extensions.html#Support for details about the eGenix support offerings. ________________________________________________________________________ REFERENCE: <P><A HREF="http://www.lemburg.com/files/python/">pybench 1.0</A> - Python Benchmark Suite.

Roundup 0.3.0 - an issue tracking system
by Richard Jones Nov. 22, 2001

Nov. 22, 2001

This release contains several new features which will require migration, so please read MIGRATION.txt! Big stuff in this release: - lots of bug fixes, thanks to all users for their great feedback! - much more flexible administration tool - much better handling of errors - more configuration options - CGI login uses cookies instead of basic auth - passwords are encoded in the database - much, much more: see the CHANGES file for details. Source and documentation is available at the website: http://roundup.sourceforge.net/ Release Info (via download page): http://sourceforge.net/project/showfiles.php?group_id=31577 Mailing lists - the place to ask questions: http://sourceforge.net/mail/?group_id=31577 About Roundup ============= Roundup is a simple-to-use and -install issue-tracking system with command-line, web and e-mail interfaces. It is based on the winning design from Ka-Ping Yee in the Software Carpentry "Track" design competition. Note: Ping is not responsible for this project. The contact for this project is richard(a)users.sourceforge.net. Roundup manages a number of issues (with flexible properties such as "description", "priority", and so on) and provides the ability to (a) submit new issues, (b) find and edit existing issues, and (c) discuss issues with other participants. The system will facilitate communication among the participants by managing discussions and notifying interested parties when issues are edited. One of the major design goals for Roundup that it be simple to get going. Roundup is therefore usable "out of the box" with any python 2.0+ installation. It doesn't even need to be "installed" to be operational, though a disutils-based install script is provided. It comes with two issue tracker templates and three database back-ends.
