What's New in Python 3.3
by Raymond Hettinger Aug. 13, 2012

Aug. 13, 2012

Hello all, I'll soon be starting the edits of Whatsnew for 3.3. When I did this for 3.2, it took over 150 hours of work to research all the changes. This time there are many more changes, so my previous process won't work (reviewing every "new in 3.3" entry in the docs, every entry in the voluminous Misc/NEWS file, etc). You can help out by checking-in draft entries for your favorite new features. That way, I can avoid the time consuming curation step and focus on the text, organization, … [View More]

[RELEASED] Python 3.3.0 beta 2
by Georg Brandl Aug. 12, 2012

Aug. 12, 2012

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 On behalf of the Python development team, I'm happy to announce the second beta release of Python 3.3.0 -- a little later than originally scheduled, but much better for it. 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 … [View More]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! (*) Please note that this document is usually finalized late in the release cycle and therefore may have stubs and missing entries at this point. - -- 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) iEYEARECAAYFAlAnxVAACgkQN9GcIYhpnLAECACcDeE+N2AfYVnuwMkq682znfDU ODAAn0J87+MVA9WHEV5iYZd3ub9ZhbpC =LvY0 -----END PGP SIGNATURE----- [View Less]

SPARC testers (and buildbot!) needed
by Stefan Krah Aug. 10, 2012

Aug. 10, 2012

Hello, currently the only cheap way for developers to test on SPARC that I'm aware of is using this old Debian qemu image: http://people.debian.org/~aurel32/qemu/sparc/ That image still uses linuxthreads and may contain any number of platform bugs. It is currently impossible to run the test suite without bus errors, see: http://bugs.python.org/issue15589 Could someone with access to a SPARC machine (perhaps with a modern version of Debian-sparc) grab a clone from http://hg.python.org/… [View More]
