24 Sep '12

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 On behalf of the Python development team, I'm delighted to announce the third release candidate of Python 3.3.0. This is a preview release, and its use is not recommended in production settings. Python 3.3 includes a range of improvements of the 3.x series, as well as easier porting between 2.x and 3.x. Major new features and changes in the 3.3 release series are: * PEP 380, syntax for delegating to a subgenerator ("yield from") * PEP 393, flexible string representation (doing away with the distinction between "wide" and "narrow" Unicode builds) * A C implementation of the "decimal" module, with up to 80x speedup for decimal-heavy applications * The import system (__import__) now based on importlib by default * The new "lzma" module with LZMA/XZ support * PEP 397, a Python launcher for Windows * PEP 405, virtual environment support in core * PEP 420, namespace package support * PEP 3151, reworking the OS and IO exception hierarchy * PEP 3155, qualified name for classes and functions * PEP 409, suppressing exception context * PEP 414, explicit Unicode literals to help with porting * PEP 418, extended platform-independent clocks in the "time" module * PEP 412, a new key-sharing dictionary implementation that significantly saves memory for object-oriented code * PEP 362, the function-signature object * The new "faulthandler" module that helps diagnosing crashes * The new "unittest.mock" module * The new "ipaddress" module * The "sys.implementation" attribute * A policy framework for the email package, with a provisional (see PEP 411) policy that adds much improved unicode support for email header parsing * A "collections.ChainMap" class for linking mappings to a single unit * Wrappers for many more POSIX functions in the "os" and "signal" modules, as well as other useful functions such as "sendfile()" * Hash randomization, introduced in earlier bugfix releases, is now switched on by default In total, almost 500 API items are new or improved in Python 3.3. For a more extensive list of changes in 3.3.0, see http://docs.python.org/3.3/whatsnew/3.3.html To download Python 3.3.0 visit: http://www.python.org/download/releases/3.3.0/ Please consider trying Python 3.3.0 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 3.3's contributors) -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.19 (GNU/Linux) iEYEARECAAYFAlBf+0cACgkQN9GcIYhpnLBqfgCglbN63XUr2m4Ya4ff8Hza1Axl SgMAniQZRJi8uYfeqltf5/G4QV/+SdWT =KXTo -----END PGP SIGNATURE-----

If you want to present your own thing we will have 5 minute lightning talks where anybody can come up the stage to share the latest hacker adventures. On the second conference day we organize Python sprints. Those who would like to be involved in Python core development have now the opportunity to learn how to become a contributor. You can also get involved in Robot framework to build your human-friendly acceptance test cases. Our kind sponsor Google has travel grants for students. Please see the registration page for further details. Non-students can participate to the social dinner event. But don’t worry... we have evening activities organized for the students too! Please note that the speakers list is still not final and we will announce more speakers later. Also more information about the venue and travelling to Helsinki is coming.

pytest-timeout 0.3: py.test plugin to abort long-running tests
by Floris Bruynooghe 19 Sep '12

19 Sep '12

Hello all, I am pleased to announce the release of pytest-timeout 0.3. http://pypi.python.org/pypi/pytest-timeout/0.3 pytest-timeout is a plugin for py.test which allows you to abort tests after a specific timeout. This is useful to e.g. handle hanging tests on a continuous integration server. When tests are aborted you will get stack dumps of all threads in the python process to help you debug why the test hung. All feedback is welcome. Please use the bug tracker on bitbucket to report any issues: https://bitbucket.org/flub/pytest-timeout/ Changelog since 0.2: * Added the PYTEST_TIMEOUT environment variable as a way of specifying the timeout (closes issue #2). * More flexible marker argument parsing: you can now specify the method using a positional argument. * The plugin is now enabled by default. There is no longer a need to specify ``timeout=0`` in the configuration file or on the command line simply so that a marker would work. Regards, Floris

[ANN] python-blosc 1.0.5 released
by Francesc Alted 16 Sep '12

16 Sep '12

============================= Announcing python-blosc 1.0.5 ============================= What is it? =========== A Python wrapper for the Blosc compression library. Blosc (http://blosc.pytables.org) is a high performance compressor optimized for binary data. It has been designed to transmit data to the processor cache faster than the traditional, non-compressed, direct memory fetch approach via a memcpy() OS call. Blosc works well for compressing numerical arrays that contains data with relatively low entropy, like sparse data, time series, grids with regular-spaced values, etc. What is new? ============ - Upgraded to latest Blosc 1.1.4. - Better handling of condition errors, and improved memory releasing in case of errors (thanks to Valentin Haenel and Han Genuit). - Better handling of types (should compile without warning now, at least with GCC). For more info, you can see the release notes in: https://github.com/FrancescAlted/python-blosc/wiki/Release-notes More docs and examples are available in the Quick User's Guide wiki page: https://github.com/FrancescAlted/python-blosc/wiki/Quick-User's-Guide Download sources ================ Go to: http://github.com/FrancescAlted/python-blosc and download the most recent release from there. Blosc is distributed using the MIT license, see LICENSES/BLOSC.txt for details. Mailing list ============ There is an official mailing list for Blosc at: blosc(a)googlegroups.com http://groups.google.es/group/blosc -- Francesc Alted
