Python 2.3a1 released
by Guido van Rossum 31 Dec '02

31 Dec '02

I'm happy to announce the successful release of Python 2.3a1 tonight, on Dec 31 (in *some* timezones :-). Go pick it up from its home page: http://www.python.org/2.3/ This is an alpha release: if you have Python code that's important (to you), please test it thoroughly with this release, but don't use the release for production runs. Please report any problems to the SourceForge bug tracker: http://sourceforge.net/bugs/?group_id=5470 What's new? The language isn't changing much this time. Instead, we have lots of new or improved standard library modules: bsddb, bz2, datetime, heapq, logging, optparse, ossaudiodev, random (Mersenne Twister algorithm), sets, socket (added timeouts), textwrap, and zipimport. That's right, you can now import modules from zip files. More elaborate news is on the website: http://www.python.org/2.3/highlights.html (brief) http://www.python.org/doc/2.3a1/whatsnew/ (extensive) http://www.python.org/2.3/NEWS.html (exhausting) --Guido van Rossum (home page: http://www.python.org/~guido/)

Updated Cygwin Package: python-2.2.2-4
by Jason Tishler 31 Dec '02

31 Dec '02

New News: === ==== I have updated the version of Python to 2.2.2-4. The tarballs should be available on a Cygwin mirror near you shortly. The main purpose of this release is to rebuild the _tkinter module against the latest Cygwin tcltk package. Additionally, the _socket module is *no* longer built as a static module to workaround a Cygwin fork() issue due to DLL base address conflicts. Note that this workaround does not works with the current Cygwin release. Instead, if you are experiencing fork() failures, then you must rebase your Cygwin system. See the README for more details. 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-2.2.2.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] custom 0.3 released
by Luke Kenneth Casson Leighton 29 Dec '02

29 Dec '02

Note by the author ------------------ the history of this project is that it is a live-running and also continuously developing project to meet a hard-nosed businesses needs. the decision to make it open source has been considered for some time, and recently actioned. the primary motivation for releasing Custom as open source is to make it possible for managers and developers to use Custom, not just myself and the day-to-day staff at the business where Custom is in use. on with the release notes... Custom ------ custom is an e-commerce solution for small to medium-sized businesses that provides: - a web front-end for customers and Point-of-Sale staff to place orders - for warehouse staff to manage stock - for accountants and sales staff to manage and generate invoices - for purchasing managers to keep track of suppliers and competitive pricing. Download -------- http://sf.net/projects/custom Requirements ------------ This package requires or uses the following software, where the MySQL or MS-SQL package need not necessarily be installed on the same server as the rest: - Python 2.1 or greater (http://python.org) - EITHER: - MySQL client libraries (http://mysql.org) - Andy Dustman's MySQLdb package (requires MySQL client) (http://sf.net/projects/mysqldb) OR: - Pysxqmll (a Python / MS-SQL / XML client for MS-SQL 2000) (http://sf.net/projects/pysxqmll) [what a stupid name.] - The mxDateTime and DateTime packages (http://starship.skyport.net/~lemburg/mxDateTime.html) - PyCrypto version 1.9a1 or greater (http://sf.net/pycrypto) In case you were wondering, PostgreSQL is under investigation to be added into the database abstraction system that custom uses. custom uses some features in the SocketServer class that were introduced in Python 2.1. If you wish to stick with Python 2.0, you may wish to copy over the SocketServer.py file from the distribution of Python 2.1 or greater, and use that (making sure that you back up your original SocketServer.py file!) SQL --- You must also install MySQL or MS-SQL 2000 on a server, where you may wish to install the SQL server on a separate system. A high-availability cluster pair is recommended, under which circumstances, if you are considering HA, you should NOT install the custom package on the same box as the SQL database. Yet. Optional requirements --------------------- A barcode scanning device, such as those available from Worth Data (www.pcbarcode.com) that reads EAN and other barcodes and pretends to be a USB keyboard, proves to be very useful. If you are running Linux, install the full HID USB device module and the Input Device and Keyboard support modules: CONFIG_INPUT=m CONFIG_INPUT_KEYBDEV=m CONFIG_USB_HID=m Do not be fooled into installing the partial HID USB keyboard device (CONFIG_USB_KBD) on its own, because it won't work, you MUST install the full HID support. TODO ---- - Create website to describe custom - Create user documentation - Move as much administration into SQL as possible NOTES ----- Please read the INSTALL.txt notes in each directory. The order of installation of the packages is not important, however in order to run the start-up commands specified in the INSTALL.txt notes, you should follow the instructions to the letter, in the following order: - pysqldb/ - cgi/ - Example/ - db/ The purpose of each package is explained below: - pysqldb/ pysqldb contains the package DPyDB which is a collection of SQL abstraction and configuration management classes. - cgi/ cgi contains the HTML dynamic content generation scripts for your site. this is the back-bone of the custom package. however, the formatting and presentation of the HTML is left to some base classes, and you are expected to write your own formatting classes, with the Example/ site presentation classes as... well... examples :) for you to base them on. - Example/ Example/ contains some classes responsible for presentation of your web site, and it also contains the configuration file for the whole package, /etc/custom.conf. If you wish to start creating your own web site immediately, you should copy this entire subdirectory, global/search replace the word "Example" in all files with your own appropriate directory name, and start from there. Typical examples of the functions used are print_html and print_footer, which, funnily enough, output the HTML content at the start and end of every web page, respectively. This is the bit where you may wish to consult with other users of custom, or to hire the author to help with your site design... - db/ db contains all the database management routines used by both the front-end and the back-end of the custom package. db depends on pysqldb, and in turn, the cgi scripts and back-office program monitord.py depend on db/

ANN: Cog object database v0.3
by Itamar Shtull-Trauring 28 Dec '02

28 Dec '02

Cog is the Checkpointed Object Graph object database, providing semi-transparent persistence for large sets of interrelated Python objects. It handles automatic loading of objects on reference, and saving of modified objects back to disk. Reference counting is used to automatically remove no longer referenced objects from storage, and objects will be automatically be attached to the database if a persistent object references them. Cog does not provide traditional transaction support. Instead, it provides only a way to flag the database as self-consistent, and guarantees that on system restart, the database will be restored to the most recent possible self-consistent state. Cog was originally written by Oliver Jowett (http://www.randomly.org).

Jay, this is my view from NYC
by Byron 28 Dec '02

28 Dec '02

a very skillful attack who profits? -Israeli incursions in two P.A. towns -the largest British fleet organized in eighteen years "coincidentally" has been on route for days nearing the Middle East for "maneuvers" -America asking for coalition of global powers for new "counter-insurgent" war... a planetary Vietnam. Rather then seriously ask why people would kill themselves and so many others, "we" put an answer in their mouths and say, -Prez-"they attack us because we are the bastion of freedom in the world." period.... Some introspection? No. Respect for the enemy? No. Understanding the enemy? No. That is why the forces of reaction do not know what the terms are or what to do. These are the fruits of the politics of denial. We deny the complaints of our victims, even deny they are our victims, and blind ourselves to a planet of enmity. Understanding this, as I have long fruitlessly preached as a "lunatic", one must take one of three possible courses: X) Understand ones position of domination, take every defensive measure, and terrorize the dominated. Y) Deny ones imperial position and be over run by a million cuts Z) Discard past paradigms worn thin since times before pharaoh, make a detente for all humankind and all the rest of nature, including a transformation in our relationships to the Earth and human to human. The standing "American authorities" want solution Y with a big war on the dispossessed, Islam, and the rest. It would be the fourth world war since the sheep in America seem to have missed the third one. Our "leaders" are inept, impotent, and culpable in one of two ways. First: For a second "hijacked" commercial jet to strike the most critical concentration in the global capitalist economy, twenty minutes after the first, and with no military response, is profound negligence. Particularly in the wake of the 1993 WTC attack, the success of this attack is pure negligence...or... complicity. If it is simple puerile negligence, then the governor of NY, and the mayor of NYC, who are so busy congratulating and patting each other on the back for what a great job they have done, should resign in shame and utter humiliation for their total failure. Also former governor Cuomo should beg the forgiveness of his constituents and the greater public. The joint chiefs of staff, as well as all regional military and air commanders should resign or be court-martialed for negligence. The current administration as well as members of senate and house intelligence and military committees should be removed from office and placed under house arrest for extensive questioning. The former administration should be likewise detained. All planning staffs for civil defense and air security should be detained and questioned, if not court marshaled. That is if an enemy attacked us. If there was, however, foreknowledge by any elements of our government, there should be a grand jury, and also a global response. There have been many comparisons today and since the annihilation of the WTC with Pearl Harbor, the attack on Hawaii in 1941. Years of speculation over the absence of our vital air-craft carriers at that attack, as well as myriad evidence, points to a foreknowledge by F.D.R. which is confirmed by a decade of public study of the code breaking facts of Ultra Mega. Many times after Pearl Harbor the British and Americans allowed their own troop ships to go to the bottom rather than reveal to the enemy that all their codes were useless. This was rationalized then and now as expedient both to motivate the American public to eagerness for war and to help finally win it. Today what would be the motive? In a world that should head for peace we have a threatened way of life, the global capitalist military industrial "complex". In need of perceived enemies and great battles, and willing to accept at least a police state "counter-insurgency" planetary domination system, would they sacrifice the WTC? Symbolically it will inspire hundreds of thousands of those disenfranchised with western freedom to fight and seek training and organizations that can help them achieve something so grand. There is our enemy, since realistically China has not invaded its neighbors significantly for a thousand year and is not likely to threaten the U.S.(only Tibet, and maybe one of Siberia.... wait and see-either way the U.S. never even did anything about Tibet) So now around the world we will have tight security which will not stop anything and the police state planet NWO will attempt to take control and will, basically if they are not stopped here. Guilty or innocent the current authorities have to go, for America and the Earth Feel free to distribute my views... What was it an attack against? a view from NYC: 14sep2001 -- They are cleaning with the cafe now, won't attack smogs later.

PyWX 1.0b2 release (Python for AOLserver)
by Titus Brown 27 Dec '02

27 Dec '02

We are pleased to announce the release of PyWX version 1.0b2. This is our second beta release; it is known to be fairly stable. PyWX can be retrieved from SourceForge, http://download.sourceforge.net/PyWX/PyWX-1.0b2.tar.gz The PyWX homepage is http://pywx.idyll.org What is PyWX? ------------- PyWX is a Python module for AOLserver. AOLserver is a free, open-source, enterprise-class, multi-threaded web server whose performance on dynamic content is reputed to beat Apache. It is used at many large web sites including AOL and ArsDigita. It includes an internal database API that allows persistent database connections. Python is a clean, object-oriented scripting language with excellent support for complicated data structures and great libraries for web programming. PyWX embeds a Python interpreter into AOLserver, allowing threaded execution of Python scripts--even CGI scripts--within the server process. It also allows the Python script to access almost all of AOLserver's internal API via a C extension module. PyWX supports many other features, including + Threaded execution of CGI scripts within emulated CGI environment. + Cross-connection data-persistence. + Access to AOLserver's persistent database mechanism. + Internal Webware and Quixote adaptors. + Pretty good documentation. + Object-oriented Python wrapping of AOLserver's C API functions. Almost all of AOLserver's facilities are available to Python scripts. + Full access to AOLserver's Tcl interpreter from Python, and vice versa. + Optional compiled-script caching. What's new in version 1.0b2? ---------------------------- + configuration script now works properly, documentation updated. + Fixes for gcc 3.x. + Fix for a memory leak (the last detectable one!). + Several fixes for handling POSTed multipart/form-data. + Fix for uncaught exception. + Cleanup of internal HTTP header handling. + Extreme simplification of internals, fix of a crashing bug. + Update for AOLserver 3.5. + Added a handler for the Quixote application server. + Fixed unnecessary proliferation of end-of-connection callbacks. Version 1.0b2 is a bug fix version for 1.0b1 that has been tested over the past year and a half. It is currently used in several stable projects, and there are no known bugs remaining. As a rough measure of its current performance, without optimizing the machine PyWX can deliver a trivial Python script at roughly 230-310 pages per second on a single-processor Pentium 3/500MHz under Linux, and a trivial Oracle database-querying script at about 75-90 pages/s. (The range depends on PyWX configuration.) Please check out our home page at http://pywx.idyll.org and our SourceForge project page at http://sourceforge.net/projects/pywx/ for more information on PyWX, including mailing lists, development archives, and several example pages. You may also be interested in: http://www.aolserver.com -- AOLserver http://www.python.org -- the Python programming language http://webware.sourceforge.net -- Webware toolkit http://www.mems-exchange.org/software/quixote/ -- Quixote toolkit Cheers, Titus Brown for the PyWX team.
