Mailman 3 August 2003 - Python-announce-list

PyCon DC 2004 Kickoff!
by PyCon Committee Aug. 4, 2003

Aug. 4, 2003

[Posted to comp.lang.python/python-list, comp.lang.python.announce, zope-announce, pycon-announce, and python-dev.] [Please repost to local Python mailing lists.] Planning for PyCon DC 2004, the Python community conference, is now underway. DC 2004 will be held March 24-26, 2004 in Washington, D.C. It will contain many of the features of this year's successful conference, including a development sprint and a similar cost structure. Registration will be open by October 1. A Call For Proposals will be issued in the next two weeks. Presentations will be required in electronic form for publication on the web. PyCon DC 2003 had a broad range of presentations, from reports on academic and commercial projects to tutorials and case studies, and these will all be included in the Call For Proposals. As long as the presentation is interesting and potentially useful to the Python community, it will be considered for inclusion in the program. There will again be a significant amount of Open Space to allow for informal and spur-of-the-moment presentations for which no formal submission is required. There will also be several Lightning Talk sessions. These informal sessions are opportunities for those who don't want to make a formal presentation. We're looking for volunteers to help run PyCon. If you're interested, subscribe to http://mail.python.org/mailman/listinfo/pycon-organizers Don't miss any PyCon announcements! Subscribe to http://mail.python.org/mailman/listinfo/pycon-announce You can discuss PyCon with other interested people by subscribing to http://mail.python.org/mailman/listinfo/pycon-interest The central resource for PyCon DC 2004 is http://www.python.org/pycon/dc2004/ -- Aahz (aahz(a)pythoncraft.com) <*> http://www.pythoncraft.com/ This is Python. We don't care much about theory, except where it intersects with useful practice. --Aahz

[ANNOUNCE] e4Graph 1.0a8 released
by jyl＠e4graph.com Aug. 4, 2003

Aug. 4, 2003

I am pleased to announce the 1.0a8 release of e4Graph, the eight Alpha release. WHAT IS IT: e4Graph is a C++ library that allows programs to store graph-like data persistently and to access and manipulate that data efficiently. With e4Graph, you can arrange your data in the most natural form that reflects the relationships between its parts, rather than having to force it into a table-like format. The e4Graph library also allows you to concentrate on the relationships you want to represent, and not on how to store them in a database. You can modify data items, and add and remove connections and relationships between pieces of data on the fly. e4Graph allows you to represent an unlimited number of different connections between pieces of data, and your program can selectively manipulate the data according to the relationships it cares about, not having to know about other connections represented in the data set. The e4Graph package also provides bindings in several other languages, currently Tcl, Python and Java, and allows input/output of object graphs via an XML representation. The e4Graph package is built on top of Metakit 2.4.9.2, and optionally uses Tcl 8.4.4, Python 2.2.3, Java 1.1 or later, and Expat 1.95.5. WHERE TO GET: Downloads: http://sourceforge.net/projects/e4graph/ Homepage: http://www.e4graph.com/e4graph/ Changelog: http://www.e4graph.com/e4graph/changes.txt Installation: http://www.e4graph.com/e4graph/e4install.html WHAT IS NEW: Support for MacOS X 10.2 and several other platforms was added. Support for Python 2.2 and later releases was added. The Java binding was updated. The event mechanism was completely overhauled and support for user defined events was added. The vertex caching mechanism was moved from the Tcl binding to the core e4Graph library to enable other language bindings to benefit from the increased performance afforded by the cache. The interface between e4Graph and data base drivers was formalized in preparation for supporting new data base drivers in addition to Metakit. Additional work was done to support 64-bit systems and very large storages; more work is needed. Support for SWIG was added so new language bindings can be created with SWIG, in preparation for incorporating Perl, PHP and Ruby bindings in the next release. Many bugs were fixed. ACKNOWLEDGMENTS: Michael Krimerman contributed the Python binding. J.P. Fletcher helped me get started with SWIG support. Joe Mistachkin provided access to a FreeBSD host for testing. Daniel Steffen and Nicholas Brawn were instrumental helping with MacOS X support. I wish to acknowledge support from the HP test-drive facility and from the SourceForge compile farm. Many people (too many to mention) contributed bug reports and bug fixes. Geoff Shapiro and David Van Maren suggested many useful API changes.

New python-mode project at SourceForge
by Barry Warsaw Aug. 2, 2003

Aug. 2, 2003

I no longer have time to properly maintain python-mode.el, so in the fine open source tradition, I've started a SourceForge project and a mailing list for python-mode. Skip and Ken are co-admins of the project, so this way we can give people access to python-mode without going through the rigamarole of making them committers on the Python project. python-mode(a)python.org is the mailing list (it used to be just an alias). http://sf.net/projects/python-mode is the project. Both are only minimally set up at the moment (I couldn't access cvs tonight so I haven't installed python-mode.el yet). We still need to decide what to do about Misc/python-mode.el. I propose we do imports from the python-mode project at appropriate times. Anyone hacking on python-mode.el should stop doing that in the Python project. Feel free to subscribe to the mailingl ist if you want to help. -Barry

PyBackend: A simple RDBMS backed object persistence framework
by raghuprasad＠yahoo.com Aug. 2, 2003

Aug. 2, 2003

Hi! I am glad to announce the availability of an RDBMS backed object persistence framework in Python. It is in beta version, which means some hidden bugs may be there. It is available under GNU LGPL. So you can try it in your commercial applications too. Following are some of its features, straight ripped out from the project page: * It can store (as well as retrieve) attributes of objects in (from) a relational database supporting atomic transactions. * It allows you to map individual classes to corresponding databases. Hence an application can use multiple databases to populate its objects; all transparent to the application programmer. * It stores all information pertaining to the classes, attributes, databases, database authentication and number of connections per database etc. in a single text based configuration file. * It frees the application programmer from the task of creating and managing database connections. It creates such connections on demand. Maximum number of database connections for each database can be specified as a configuration option. * If your class interact with the database in more complex ways, you can execute your queries directly too. In this case you need not manage any database connections at all. You will get a handle to the correct database to which your class is mapped. * It can ensure atomic transactions even over multiple discrete operations; like over multiple HTTP/XMLRPC requests. Though not used in normal object management, this feature can be quite handy when you want to reserve a database connection exclusively for a particular use, even in a multi threaded application. Details are available at its project page: http://pybackend.sourceforge.net Hope it helps someone:-) cheers Raghu

ANN: Anobind 0.5.0
by Uche Ogbuji Aug. 1, 2003

Aug. 1, 2003

http://uche.ogbuji.net/tech/4Suite/anobind Anobind is a Python/XML data binding, which is just a fancy way of saying it's a very Pythonic XML API. You feed Anobind an XML document and it returns a data structure of corresponding Python objects. For example, the document <monty> <python spam="eggs">What do you mean "bleh"</python> <python ministry="abuse">But I was looking for argument</python> </monty> Would become a set of objects so that you could write binding.monty.python.spam In order to get the value "eggs" or binding.monty.python[1].text_content() In order to get the value "But I was looking for argument". There are other such tools for Python, and what makes Anobind unique is that it's driven by a very declarative rules-based system for binding XML to the Python data. One can register rules that are triggered by XPatterns or plain Python code in order to register specialized binding behavior. It also offers XPath support and some support for round-tripping documents. Anobind is open source, provided under the 4Suite variant of the Apache license. It requires Python 2.2.2 and 4Suite 1.0a3. -- Uche Ogbuji Fourthought, Inc. http://uche.ogbuji.net http://4Suite.org http://fourthought.com XML Data Bindings in Python, Part 2 - http://www.xml.com/pub/a/2003/07/02/py-xml.html Introducing Examplotron - http://www-106.ibm.com/developerworks/xml/library/x-xmptron/ Charming Jython - http://www-106.ibm.com/developerworks/java/library/j-jython.html Python, Web services, and XSLT - http://www-106.ibm.com/developerworks/xml/library/ws-pyth13/ A custom-fit career in app development - http://www.adtmag.com/article.asp?id=7744

Updated Cygwin Package: python-2.3-1
by Jason Tishler Aug. 1, 2003

Aug. 1, 2003

New News: === ==== I have updated the version of Python to 2.3-1. The tarballs should be available on a Cygwin mirror near you shortly. Note this package was built against Cygwin 1.3.22-1. Hence, it is *not* a 64-bit, Cygwin 1.5.x test package. Old News: === ==== Python is an interpreted, interactive, object-oriented programming language. If interested, see the Python web site for more details: http://www.python.org/ Please read the README file: /usr/doc/Cygwin/python-2.3.README since it covers requirements, installation, known issues, etc. To update your installation, click on the "Install Cygwin now" link on the http://cygwin.com/ web page. This downloads setup.exe to your system. Then, run setup and answer all of the questions. Note that we have recently stopped downloads from sources.redhat.com (aka cygwin.com) due to bandwidth limitations. This means that you will need to find a mirror which has this update. In the US, ftp://mirrors.rcn.net/mirrors/sources.redhat.com/cygwin/ is a reliable high bandwidth connection. In Germany, ftp://ftp.uni-erlangen.de/pub/pc/gnuwin32/cygwin/mirrors/cygnus/ is usually pretty good. In the UK, http://programming.ccp14.ac.uk/ftp-mirror/programming/cygwin/pub/cygwin/ is usually up-to-date within 48 hours. If one of the above doesn't have the latest version of this package then you can either wait for the site to be updated or find another mirror. The setup.exe program will figure out what needs to be updated on your system and will install newer packages automatically. If you have questions or comments, please send them to the Cygwin mailing list at: cygwin(a)cygwin.com . I would appreciate if you would use this mailing list rather than emailing me directly. This includes ideas and comments about the setup utility or Cygwin in general. If you want to make a point or ask a question, the Cygwin mailing list is the appropriate place. *** CYGWIN-ANNOUNCE UNSUBSCRIBE INFO *** If you want to unsubscribe from the cygwin-announce mailing list, look at the "List-Unsubscribe: " tag in the email header of this message. Send email to the address specified there. It will be in the format: cygwin-announce-unsubscribe-you=yourdomain.com(a)cygwin.com Jason -- PGP/GPG Key: http://www.tishler.net/jason/pubkey.asc or key servers Fingerprint: 7A73 1405 7F2B E669 C19D 8784 1AFD E4CC ECF4 8EF6

ANN: managesieve 0.3
by Hartmut Goebel Aug. 1, 2003

Aug. 1, 2003

Announcing: managesieve ============= Version 0.3 A MANGAGESIEVE client library for remotely managing Sieve scripts, including an interactive 'sieveshell'. This module allows accessing a Sieve-Server for managing Sieve scripts there. For more information about the MANAGESIEVE protocol see draft http://www.ietf.org/internet-drafts/draft-martin-managesieve-04.txt . Changes since 0.2 ----------------- * managesieve: - MANAGESIEVE.authenticate() now only returns a OK/NO/BYE result like any command not asking data from the server * sieveshell: - added 'edit', which may create scripts, too. (posix only) - now prints out the server capabilities, thus the user knows what ther server is capable of (and which Sieve-Commands may be used). - fixed some minor bugs - sieveshell was missing in archive What is MANAGESIEVE? -------------------- Sieve scripts allow users to filter incoming email. Message stores are commonly sealed servers so users cannot log into them, yet users must be able to update their scripts on them. This module implements a protocol "managesieve" for securely managing Sieve scripts on a remote server. This protocol allows a user to have multiple scripts, and also alerts a user to syntactically flawed scripts. This an interim measure as it is hoped that eventually Sieve scripts will be stored on ACAP. Availablity ----------- 'managesieve' is available for download at http://www.crazy-compilers.com/py-lib/managesieve.html Requirements ------------ Requires Python >= 2.0 Not yet implemented ------------------- - Only athentication method LOGIN is currently supported. - STARTTLS is not yet implemented. - sieve-names are only quoted dump (put into quotes, but no escapes yet). Copyright/License ----------------- (C) Copyright 2003 by Hartmut Goebel <h.goebel(a)crazy-compilers.com> License: Python Software Foundation License http://www.opensource.org/licenses/PythonSoftFoundation.html License for 'sieveshell' and test suite: GPL http://www.opensource.org/licenses/gpl-license.php Credits ------- Based on Sieve.py from Ulrich Eck <ueck(a)net-labs.de> which is part of of 'ImapClient' (see http://www.zope.org/Members/jack-e/ImapClient), a Zope product. Some ideas taken from imaplib written by Piers Lauder <piers(a)cs.su.oz.au> et al. -- Regards Schönen Gruß Hartmut Goebel -- | Hartmut Goebel | IT-Security -- effizient | | h.goebel(a)goebel-consult.de | www.goebel-consult.de |
