ANNOUNCE: flufl.bounce 2.2
by Barry Warsaw 21 Jun '13

21 Jun '13

I am happy to announce flufl.bounce version 2.2. The flufl.bounce library provides a set of heuristics and an API for detecting the original bouncing email addresses from a bounce message. Many formats found in the wild are supported, as are VERP and RFC 3464 (DSN). flufl.bounce is the bounce detection library used by GNU Mailman. flufl.bounce is compatible with Python 2.6, 2.7, 3.2, and 3.3. My deep gratitude to Mark Sapiro for his help in preparing the 2.2 release. Thanks also to the other contributors named below. Here's what's new in version 2.2: * Added recognition for a bogus Dovecot over-quota rejection sent as an MDN rather than a DSN. (LP: #693134) * Tweaked a simplematch regexp that didn't always work. (LP: #1079254) * Added recognition for bounces from mail.ru. Thanks to Andrey Rahmatullin. (LP: #1079249) * Fixed UnicodeDecodeError in qmail.py with non-ascii message. Thanks to Theo Spears. (LP: #1074592) * Added recognition for another Yahoo bounce format. Thanks to Mark Sapiro. (LP: #1157961) * Fix documentation bug. (LP: #1026403) * Document the zope.interface requirement. (LP: #1021383) Full documentation is available here: http://pythonhosted.org/flufl.bounce/ The project home page is at: https://launchpad.net/flufl.bounce You can report bugs at: https://bugs.launchpad.net/flufl.bounce Download the package from the Cheeseshop: https://pypi.python.org/pypi/flufl.bounce Enjoy, -Barry

[ANN] ErlPort (library to connect Erlang to Python) 1.0.0alpha released
by Dmitry Vasilev 11 Jun '13

11 Jun '13

Hi all, I've just released ErlPort version 1.0.0alpha. ErlPort is a library for Erlang which helps connect Erlang to a number of other programming languages (currently supported Python and Ruby). Apart from using ErlPort as a tool to call Python/Ruby functions from Erlang it also can be used as a middleware for Python/Ruby instances. Check http://erlport.org for more details. The new version of ErlPort is basically a complete redesign and rewrite of the project. The main changes in this version are: - Redesigned as Erlang application - Added support for all recent (2.5 and higher) versions of Python - Added support for all recent (1.8.6 and higher) versions of Ruby - Added support for custom data types Why ErlPort can be interesting for Python developers? ----------------------------------------------------- Apart from calling Python functions from Erlang or Erlang function from Python, ErlPort also allows to use Erlang as a middleware for Python. The following is a small inter-process recursion example (place it in roll.py file). Actually this example will be even simpler with ErlPort 1.0.0. from os import getpid from erlport.erlterms import Atom from erlport.erlang import call, self def roll(n, procs=None): if procs is None: procs = [] procs.append(self()) print "Hello from %s" % getpid() if n > 1: status, pid = call(Atom("python"), Atom("start"), []) if status == "ok": procs = call(Atom("python"), Atom("call"), [pid, Atom("roll"), Atom("roll"), [n - 1, procs]]) return procs And it can be used with Erlang shell and ErlPort like this: 1> {ok, P} = python:start(). {ok,<0.34.0>} 2> python:call(P, roll, roll, [5]). Hello from 7747 Hello from 7749 Hello from 7751 Hello from 7753 Hello from 7755 [<0.34.0>,<0.37.0>,<0.40.0>,<0.43.0>,<0.46.0>] -- Dmitry Vasiliev <dima at hlabs.org> http://hlabs.org http://twitter.com/hdima

devpi-0.9: pypi caching server and packaging workflow meta tool
by holger krekel 11 Jun '13

11 Jun '13

Hi all, i just released devpi-server-0.9, devpi-client-0.9 and a convenience meta "devpi-0.9" package to install them both. Main news for devpi-server, the caching pypi server: - github-style user and index management: you can upload to USER/NAME indexes with the default being "root/dev", an overlay index that serves all pypi.python.org packages and the ones you upload to it. - integrates now well with latest CDN changes, maintains a consistent quite real-time local pypi cache - redis dependency is gone, only pure Python deps left Main news for the initial release of devpi-client, the packaging workflow tool: - provides install/upload/test sub commands to perform common tasks with an index - provides user/index/use/server commands to manage context and the automated server Lastly, to get started super-quickly, there is a new site with all the docs: http://doc.devpi.net I'd like to use the 0.9 series to refine the command line interface, fix bugs and implement some more functionality before heading for a more stable 1.0 release. have fun, holger krekel

by Tim Knapp 10 Jun '13

10 Jun '13

Hi, The Kiwi PyCon 2013 Organising Committee would like to announce the availability of the Kiwi PyCon 2013 Financial Aid program. The program's purpose is to make the conference accessible to everyone, particularly those who due to financial difficulties would otherwise not be able to attend. We are particularly interested in potential speakers as it would be a shame for the conference to miss out on your talk contribution merely due to financial concerns. Further information regarding the program can be found here: http://nz.pycon.org/financial-aid/ And don't forget the Call for Proposals ends next Tuesday, June 18 so please get those talk/tutorial submissions in! -- Kind regards, Tim Knapp (On behalf of the Kiwi PyCon 2013 Organising Committee)
