[ANN] Release 0.66.0 of Task Coach
by Frank Niessink 31 Oct '07

31 Oct '07

Hi, I'm happy to announce release 0.66.0 of Task Coach. This release contains a few small feature enhancements, a few small bugfixes and a translation in Traditional Chinese. Bug fixed: * Make categories and category viewer more robust. Features added: * Added Traditional Chinese translation thanks to Joey Weng. * Added an 'overall categories' column that recursively shows the categories a task belongs to, i.e. its own categories and the categories of its parent task(s). * Column widths are saved between sessions. * Ctrl-PageUp and Ctrl-PageDown can be used to cycle through open viewers. What is Task Coach? Task Coach is a simple task manager that allows for hierarchical tasks, i.e. tasks in tasks. Task Coach is open source (GPL) and is developed using Python and wxPython. You can download Task Coach from: http://www.taskcoach.org In addition to the source distribution, packaged distributions are available for Windows XP/Vista, Mac OSX, and Linux (Debian and RPM format). Note that Task Coach is alpha software, meaning that it is wise to back up your task file regularly, and especially when upgrading to a new release. Cheers, Frank

PyCon 2008 - Call for Tutorials
by Greg Lindstrom 31 Oct '07

31 Oct '07

PyCon 2008 is being held in Chicago this year. The general conference is March 14-16 with the proceeding day, March 13th, being the traditional "tutorial day". We have had a lot of input on topics to cover and now we are looking for qualified instructors to sign up to present the sessions. Tutorials are 3 hours long (with break) and instructors are paid for their effort ($1000.00 + conference registration). PyCon is planned and run by volunteers just like you. Why not get involved? Pop on over to us.pycon.org <http://us.pycon.org/2008/about> for conference details or email us at pycon-tutorials(a)python.org and let us know what you would like to present as a tutorial. Thanks, --greg

Version 1.2 of mod_wsgi is now available.
by Graham Dumpleton 31 Oct '07

31 Oct '07

Version 1.2 of mod_wsgi is now available. The software and documentation are both available from: http://www.modwsgi.org The mod_wsgi package consists of an Apache web server module designed and implemented specifically for hosting Python based web applications that support the WSGI interface specification. Examples of major Python web frameworks and applications which are known to work in conjunction with mod_wsgi include CherryPy, Django, MoinMoin, Pylons, Trac and TurboGears. Version 1.2 of mod_wsgi is a bug fix only release, addressing issues with WSGI specification compliance, sub process invocation from Python in a mod_wsgi daemon process and most importantly of all, an issue whereby a second sub interpreter instance could be created for each WSGI application group when targeted by a specifically formed URL. This latter issue of a second sub interpreter being created only affects users of Apache 1.3 and 2.0. Because it can have the affect of doubling the memory in use by the application, it is highly recommended that users of these Apache versions upgrade to mod_wsgi 1.2, given that in a memory constrained environment the bug could be exploited as a form of remote denial of service attack. A description of all changes in this version can be found in the change notes at: http://code.google.com/p/modwsgi/wiki/ChangesInVersion0102 If you have any questions about mod_wsgi or wish to provide feedback, use the Google group for mod_wsgi found at: http://groups.google.com/group/modwsgi Enjoy Graham Dumpleton

ordereddict 0.4 (incl. sorteddict)
by Anthon van der Neut 30 Oct '07

30 Oct '07

I am pleased to announce version 0.4 of the ordereddict module. Changes: - added pickling - added optional relaxed initialisation/update (from unordered dicts) - added KVIO (Key Value Insertion Order ie. key moves to back on update) - implemented a seperate subtype sorteddict, with KSO (Key Sorted Order) You *can* specify a function for key transformation before comparison (such as string.lower) sorteddict does not have all of the ordereddict methods as some of them make no sense (eg. slice assignment, rename, setkeys) -------- From the blurb on ordereddict's home-page: This is an implementation of an ordered dictionary with Key Insertion Order (KIO: updates of values do not affect the position of the key), Key Value Insertion Order (KVIO, an existing key's position is removed and put at the back). Sorted dictionaries are also provided. Currently only with Key Sorted Order (KSO, no sorting function can be specified, but a transform function to be applied on the key before comparison can be supplied. It implementation is directly derived from dictobject.c and its speed is 5-10% slower than dict() and 5-9 times faster than Larosa/Foord excellent pure Python implemention. This module has been tested under: Ubuntu 7.04, gcc : Python 2.5.1 Ubuntu 7.04, gcc : Python 2.4.4 Ubuntu 6.06, gcc : Python 2.5.1 Windows XP, Visual Studio 2003: Python 2.5.1 ordereddict's home on the web is at http://www.xs4all.nl/~anthon/Python/ordereddict there you also find the links where the source can be downloaded. The .zip file there included a precompiled .pyd file for Windows.

SQLObject 0.9.2
by Oleg Broytmann 30 Oct '07

30 Oct '07

Hello! I'm pleased to announce the 0.9.2 release of SQLObject. What is SQLObject ================= SQLObject is an object-relational mapper. Your database tables are described as classes, and rows are instances of those classes. SQLObject is meant to be easy to use and quick to get started with. SQLObject supports a number of backends: MySQL, PostgreSQL, SQLite, and Firebird. It also has newly added support for Sybase, MSSQL and MaxDB (also known as SAPDB). Where is SQLObject ================== Site: http://sqlobject.org Development: http://sqlobject.org/devel/ Mailing list: https://lists.sourceforge.net/mailman/listinfo/sqlobject-discuss Archives: http://news.gmane.org/gmane.comp.python.sqlobject Download: http://cheeseshop.python.org/pypi/SQLObject/0.9.2 News and changes: http://sqlobject.org/News.html What's New ========== News since 0.9.1 ---------------- Bug Fixes ~~~~~~~~~ * Remove 'limit' from SelectResults after setting start/end so .clone() never sees limit again. * Fixed a bug in sqlbuilder._LikeQuoted() - call sqlrepr() on the expression to escape single quotes if the expression is a string. * Fixed a bug in Versioning - do not copy "alternateID" and "unique" attributes from the versioned table. * Fixed a misspelled 'zerofill' option's name. * Fixed StringCol and UnicodeCol: use sqlType with MSSQL. * Fixed startswith/endswith/contains for UnicodeCol. * Fixed bugs in SQLiteConnection.guessColumn(). Other Changes ~~~~~~~~~~~~~ * Removed SelectResults.__nonzero__, which was a design mistake. Raising an exception in __nonzero__() is inconsistent with other iterators (bool(iter([])) => True). * Changed the default value for 'varchar' in BLOBColumns from 'auto' to False (so that the default type for the columns in MySQL is BLOB, not TEXT). * Changed the implementation type in BoolCol under MySQL from TINYINT to BOOL (which is a synonym for TINYINT(1)). For a more complete list, please see the news: http://sqlobject.org/News.html Oleg. -- Oleg Broytmann http://phd.pp.ru/ phd(a)phd.pp.ru Programmers don't die, they just GOSUB without RETURN.

lxml 1.3.6 released
by Stefan Behnel 29 Oct '07

29 Oct '07

Hi all, lxml 1.3.6 is up on PyPI. This is a bug fix release for the stable 1.3 series. It features two important fixes for crash bugs. Updating is recommended. http://codespeak.net/lxml/ http://pypi.python.org/pypi/lxml/ ** Install it with $ easy_install lxml==1.3.6 ** What is lxml? """ In short: lxml is the most feature-rich and easy-to-use library for working with XML and HTML in the Python language. lxml is a Pythonic binding for the libxml2 and libxslt libraries. It is unique in that it combines the speed and feature completeness of these libraries with the simplicity of a native Python API. """ Have fun, Stefan 1.3.6 (2007-10-29) ================== Bugs fixed ---------- * Backported decref crash fix from 2.0 * Well hidden free-while-in-use crash bug in ObjectPath Other changes ------------- * The test suites now run ``gc.collect()`` in the ``tearDown()`` methods. While this makes them take a lot longer to run, it also makes it easier to link a specific test to garbage collection problems that would otherwise appear in later tests.
