[RELEASED] Python 2.7 alpha 4
by Benjamin Peterson 06 Mar '10

06 Mar '10

On behalf of the Python development team, I'm overjoyed to announce the fourth alpha release of Python 2.7. Python 2.7 is scheduled (by Guido and Python-dev) to be the last major version in the 2.x series. Though more major releases have not been absolutely ruled out, it's likely that the 2.7 release will an extended period of maintenance for the 2.x series. 2.7 includes many features that were first released in Python 3.1. The faster io module, the new nested with statement syntax, improved float repr, set literals, dictionary views, and the memoryview object have been backported from 3.1. Other features include an ordered dictionary implementation, unittests improvements, a new sysconfig module, and support for ttk Tile in Tkinter. For a more extensive list of changes in 2.7, see http://doc.python.org/dev/whatsnew/2.7.html or Misc/NEWS in the Python distribution. To download Python 2.7 visit: http://www.python.org/download/releases/2.7/ Please note that this is a development release, intended as a preview of new features for the community, and is thus not suitable for production use. The 2.7 documentation can be found at: http://docs.python.org/2.7 Please consider trying Python 2.7 with your code and reporting any bugs you may notice to: http://bugs.python.org Enjoy! -- Benjamin Peterson 2.7 Release Manager benjamin at python.org (on behalf of the entire python-dev team and 2.7's contributors)

On behalf of the Python development team, I'm pleased to announce a release candidate for the second bugfix release of the Python 3.1 series, Python 3.1.2. This bug fix release fixes numerous issues found in 3.1.1. This release candidate has been released to solicit testing and feedback over an possible regressions from 3.1.1. Please consider testing it with your library or application and reporting an bugs you encounter. This will help make the final 3.1.2 release, planned in 2 weeks time, all the more stable. The Python 3.1 version series focuses on the stabilization and optimization of the features and changes that Python 3.0 introduced. For example, the new I/O system has been rewritten in C for speed. File system APIs that use unicode strings now handle paths with undecodable bytes in them. Other features include an ordered dictionary implementation, a condensed syntax for nested with statements, and support for ttk Tile in Tkinter. For a more extensive list of changes in 3.1, see http://doc.python.org/3.1/whatsnew/3.1.html or Misc/NEWS in the Python distribution.

ANN: PyUseCase 3.2.1 - GUI testing for PyGTK and Tkinter
by Geoff Bache 05 Mar '10

05 Mar '10

Hi all, I've made a couple of bugfixes to the 3.2 release from last week. Regards, Geoff Bache A bit more detail: PyUseCase is an unconventional GUI testing tool for PyGTK and Tkinter, along with a framework for testing Python GUIs in general. Instead of recording GUI mechanics directly, it asks the user for descriptive names and hence builds up a "domain language" along with a "UI map file" that translates this language into actions on the current GUI widgets. The point is to reduce coupling, allow very expressive tests, and ensure that GUI changes mean changing the UI map file but not all the tests. Instead of an "assertion" mechanism, it auto-generates a log of the GUI appearance and changes to it. The point is then to use that as a baseline for text-based testing, using e.g. TextTest. It also includes support for instrumenting code so that "waits" can be recorded, making it far easier for a tester to record correctly synchronized tests without having to explicitly plan for this.

Version 0.3.8 of the Python config module has been released.
by Vinay Sajip 03 Mar '10

03 Mar '10

Version 0.3.8 of the Python config module has been released. What Does It Do? ================ The config module allows you to implement a hierarchical configuration scheme with support for mappings and sequences, cross-references between one part of the configuration and another, the ability to flexibly access real Python objects, facilities for configurations to include and cross-reference one another, simple expression evaluation and the ability to change, save, cascade and merge configurations. You can easily integrate with command line options using optparse. This module has been developed on python 2.3 but should work on version 2.2 or greater. A test suite using unittest is included in the distribution. A very simple configuration file (simple.cfg): # starts here message: Hello, world! #ends here a very simple program to use it: from config import Config cfg = Config(file('simple.cfg')) print cfg.message results in: Hello, world! Configuration files are key-value pairs, but the values can be containers that contain further values. A simple example - with the example configuration file: messages: [ { stream : `sys.stderr` message: 'Welcome' name: 'Harry' } { stream : `sys.stdout` message: 'Welkom' name: 'Ruud' } { stream : $messages[0].stream message: 'Bienvenue' name: Yves } ] a program to read the configuration would be: from config import Config f = file('simple.cfg') cfg = Config(f) for m in cfg.messages: s = '%s, %s' % (m.message, m.name) try: print >> m.stream, s except IOError, e: print e which, when run, would yield the console output: Welcome, Harry Welkom, Ruud Bienvenue, Yves The above example just scratches the surface. There's more information about this module available at http://www.red-dove.com/config-doc/ Comprehensive API documentation is available at http://www.red-dove.com/config/index.html As always, your feedback is most welcome (especially bug reports, patches and suggestions for improvement). Enjoy! Cheers Vinay Sajip Red Dove Consultants Ltd. Changes since the last release posted on comp.lang.python[.announce]: ===================================================== Fixed parsing bug which caused failure for negative numbers in sequences. Improved resolution logic.

ikaaro 0.61.0 released
by J. David Ibáñez 03 Mar '10

03 Mar '10

This is a Content Management System built on Python & itools, among other features ikaaro provides: - content and document management (index&search, metadata, etc.) - multilingual user interfaces and content - high level modules: wiki, forum, tracker, etc. This is the companion release of itools 0.61; most important changes in this development cycle have gone to itools, and so this ikaaro release is relatively small: - The bundled jquery has been upgraded from 1.3.2 to 1.4.2 - Minor user interface improvements here and there - Sensible speed-up, mostly due to the optimizations to the database layer in itools.handlers For further details check the UPGRADE file.

itools 0.61.0 released
by J. David Ibáñez 03 Mar '10

03 Mar '10

itools is a Python library, it groups a number of packages into a single meta-package for easier development and deployment: itools.abnf itools.ical itools.srx itools.core itools.log itools.stl itools.csv itools.odf itools.tmx itools.datatypes itools.office itools.uri itools.fs itools.pdf itools.web itools.gettext itools.pkg itools.workflow itools.git itools.python itools.xapian itools.handlers itools.relaxng itools.xliff itools.html itools.rest itools.xml itools.http itools.rss itools.xmlfile itools.i18n itools.soup The new package itools.soup is a minimal wrapper around the libsoup [1] library. Now the itools web server is based on this library, and so the API has considerably changed (check the documentation and the upgrade notes to learn more). This change improves the itools support of the HTTP protocol. The itools.vfs package has been renamed to itools.fs, and now includes a local-file-system (lfs) layer proving the same API as our virtual file system. This change is to sensibly improve performance, particularly to the itools.handlers database system. The new itools.log package offers a simple logging facility. It is inspired by the logging mechanism available in the Glib [2] library, and will eventually become just a wrapper. The ipkg-install.py and ipkg-cache-list.py scripts have been removed; now we are using "usine" [3] to automatize software deployment. The ipkg-build.py script should now work on Windows. The itools.core package has seen some additions: - the 'OrderedDict' class, for forward compatibility with Python 2.7 - the 'lazy' decorator, to make lazy properties (based on an article by Rick Copeland [4]) - the 'thingy_type' metaclass: an ongoing experiment to fusion classes & class-instances Other minor improvements include slightly better support for the ical file format. Now the libsoup library is required for the itools.http and itools.web packages. The minimum supported versions of glib and pygobject are now 2.20 and 2.18 respectively. Check the upgrade notes to learn more.

(See below.) * BUGFIX: ``pop`` now does interpolation in list values as well. * BUGFIX: where interpolation matches a section name rather than a value it is ignored instead of raising an exception on fetching the item. * BUGFIX: values that use interpolation to reference members that don't exist can now be repr'd. * BUGFIX: Fix to avoid writing '\r\r\n' on Windows when `write` is given a file opened in text mode ('w'). See below for important details on the change to using list values with string interpolation. What is ConfigObj? ============== **ConfigObj** is a simple but powerful config file reader and writer: an *ini file round tripper*. Its main feature is that it is very easy to use, with a straightforward programmer's interface and a simple syntax for config files. ConfigObj has a host of powerful features: * Nested sections (subsections), to any level * List values * Multiple line values * Full Unicode support * String interpolation (substitution) * Integrated with a powerful validation system - including automatic type checking/conversion - and allowing default values - repeated sections * All comments in the file are preserved * The order of keys/sections is preserved * Powerful ``unrepr`` mode for storing/retrieving Python data-types String Interpolation and List Values ========================= For general information on string interpolation in ConfigObj see: http://www.voidspace.org.uk/python/configobj.html#string-interpolation Since version 4.7 string interpolation is done on string members of list values. If interpolation changes any members of the list then what you get back is a /copy/ of the list rather than the original list. This makes fetching list values slightly slower when interpolation is on, it also means that if you mutate the list changes won't be reflected in the original list: >>> c = ConfigObj() >>> c['foo'] = 'boo' >>> c['bar'] = ['%(foo)s'] >>> c['bar'] ['boo'] >>> c['bar'].append('fish') >>> c['bar'] ['boo'] Instead of mutating the list you must create a new list and reassign it. -- http://www.ironpythoninaction.com/

EPD 6.1 & Upcoming Webinars
by Amenity Applewhite 02 Mar '10

02 Mar '10

March is shaping up to be as busy as ever: planning SciPy 2010 (http://conference.scipy.org/scipy2010 ), two great webinars...and a new release of EPD! *Enthought Python Distribution 6.1* In EPD 6.1, NumPy and SciPy are dynamically linked against the MKL linear algebra routines. This allows EPD users to seamlessly benefit from the highly optimized BLAS and LAPACK routines in the MKL. We were certainly expecting to observe performance improvements, but we were surprised at just how dramatic the optimizations were for applications run on dual and multi-core Intel® processors. Refer to our benchmarking tests for more info: http://www.enthought.com/epd/mkl Then try it yourself! http://www.enthought.com/products/getepd.php *Enthought March Webinars* This Friday, Travis Oliphant will lead a webinar on optimization methods in EPD. Then, on the 19th, we'll host a webinar on Python libraries for integrating C and C++ code, namely Weave, Cython, and ctypes. Enthought Python Distribution Webinar How do I... optimize? Friday, March 5: 1pm CST/7pm UTC Wait-list (for non-subscribers): email amenity(a)enthought.com Scientific Computing with Python Webinar Weave, Cython, and ctypes Friday, March 19: 1pm CST/7pm UTC Register: https://www1.gotomeeting.com/register/335697152 Enjoy!
