by Richard Jones 21 Feb '11

21 Feb '11

The second PyCon AU will be held in Sydney on the weekend of the 20th and 21st of August at the Sydney Masonic Center. http://pycon-au.org/ We are looking for proposals for Talks on all aspects of Python programming from novice to advanced levels; applications and frameworks, or how you have been involved in introducing Python into your organisation. We're especially interested in short presentations that will teach conference-goers something new and useful. Can you show attendees how to use a module? Explore a Python language feature? Package an application? We welcome first-time speakers; we are a community conference and we are eager to hear about your experience. If you have friends or colleagues who have something valuable to contribute, twist their arms to tell us about it! Please also forward this Call for Proposals to anyone that you feel may be interested. To find out more go to the official Call for Proposals page here: http://pycon-au.org/2011/conference/proposals/ The deadline for proposal submission is the 2nd of May. See you in Sydney in August!

[RELEASED] Python 3.2
by Georg Brandl 20 Feb '11

20 Feb '11

On behalf of the Python development team, I'm delighted to announce Python 3.2 final release. Python 3.2 is a continuation of the efforts to improve and stabilize the Python 3.x line. Since the final release of Python 2.7, the 2.x line will only receive bugfixes, and new features are developed for 3.x only. Since PEP 3003, the Moratorium on Language Changes, is in effect, there are no changes in Python's syntax and built-in types in Python 3.2. Development efforts concentrated on the standard library and support for porting code to Python 3. Highlights are: * numerous improvements to the unittest module * PEP 3147, support for .pyc repository directories * PEP 3149, support for version tagged dynamic libraries * PEP 3148, a new futures library for concurrent programming * PEP 384, a stable ABI for extension modules * PEP 391, dictionary-based logging configuration * an overhauled GIL implementation that reduces contention * an extended email package that handles bytes messages * a much improved ssl module with support for SSL contexts and certificate hostname matching * a sysconfig module to access configuration information * additions to the shutil module, among them archive file support * many enhancements to configparser, among them mapping protocol support * improvements to pdb, the Python debugger * countless fixes regarding bytes/string issues; among them full support for a bytes environment (filenames, environment variables) * many consistency and behavior fixes for numeric operations For a more extensive list of changes in 3.2, see http://docs.python.org/3.2/whatsnew/3.2.html To download Python 3.2 visit: http://www.python.org/download/releases/3.2/ Please consider trying Python 3.2 with your code and reporting any bugs you may notice to: http://bugs.python.org/ Enjoy! - -- Georg Brandl, Release Manager georg at python.org (on behalf of the entire python-dev team and 3.2's contributors)

Release of faulthandler 1.4
by Victor Stinner 14 Feb '11

14 Feb '11

faulthandler is a module to display the Python backtrace on a fatal error (eg. segfault), after a delay (eg. 60 minutes) or when a user signal is send (eg. SIGUSR1). Changes of the version 1.4: * Add register() and unregister() functions * Add optional all_threads argument to enable() * Limit the backtrace to 100 threads * Allocate an alternative stack for the fatal signal handler to be able to display a backtrace on a stack overflow (define HAVE_SIGALTSTACK). Not available on Windows. * Windows installer for Python 3.2(RC3) You can choose the output file (sys.stderr by default) and to dump the backtrace of the current thread (default) or of all threads. faulthandler works on Python 2.5, 2.6, 2.7, 3.1 and 3.2. It is tested on Linux, FreeBSD on Windows, it should work on any operating system.
