Hi all,

I have just released version 0.9.4 of Shed Skin, a
(restricted-)Python-(2.x)-to-C++ compiler.

This is the fourth maintenance release since 0.9, so no new major features
were added. There have been many minor improvements though, and 3 new
examples were added, bringing the total number of examples to 75.

Please see my blog for more details about the release:

holger krekel — 2013-06-14T14:47:29

Hi all,

devpi-0.9.1 is out which fixes bugs and introduces support for pushing a
tested release candidate from a private index to pypi.  See

    http://doc.devpi.net

on the ease of doing "devpi upload", "test" and "push" commands
as well as general information on the devpi-server and devpi tools.

Thanks to all issue reporters and to Andi Albrecht for his pull request.

[ANN] ErlPort (library to connect Erlang to Python) 1.0.0alphareleased

Dmitry Vasilev — 2013-06-11T13:10:59

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

Continuous Deployment Style Build System for Python

James Carpenter — 2013-05-17T14:33:14

Defend Against Fruit is focused on providing a pragmatic,
continuous deployment style build system for Python.
Current Python build systems do not properly account for
the needs of effective continuous deployment. This package
extends the Python tooling to add the missing pieces,
including integration with Artifactory.

With an eye to agile development principles and fast-feedback,
we want a build system which satisfies the following goals:

* Every SCM change-set committed should result in a
  potentially shippable release candidate.

* When a defect is introduced, we want to immediately detect
  and isolate the offending SCM change-set. This is true
  even if the defect was introduced into a library we depend upon.

* Library management should be so easy as to never impede code changes,
  even in multi-component architecture.

devpi-0.9: pypi caching server and packaging workflow meta tool

holger krekel — 2013-06-10T21:53:25

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 functi

Kiwi PyCon 2013 Financial Aid program

Tim Knapp — 2013-06-10T03:46:13

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!

numba 0.9

mark florisson — 2013-06-04T10:53:27

Numba 0.9 adds support better math functions for all supported data
types (complex and floating). The release also comes with open-sourced
generalized ufunc support from numbapro. This allows users to write a
NumPy generalized ufunc directly in python and compile it with numba.
There is now also support for long double on all platforms. The
support comes with a new dependency on llvmmath. Array expressions and
their performance have also been improved.

ANN: IMAPClient 0.10

Menno Smits — 2013-06-05T23:31:21

I'm very happy to announce IMAPClient 0.10.

IMAPClient is an easy-to-use, Pythonic and complete IMAP client library
that is much friendlier to use than the imaplib module in the standard
library. It is mature and well tested, including functional tests that
check against actual IMAP server implementations.

This is the first release to support Python 3. Python versions 2.6, 2.7,
3.2 and 3.3 are now officially supported. Support for Python 2.4 and 2.5
has been dropped.

For details on what's changed in this release please see this blog post:

ANN: A new version (0.3.4) of the Python module which wraps GnuPG hasbeen released.

Vinay Sajip — 2013-06-05T10:38:14

A new version of the Python module which wraps GnuPG has been released.

What Changed?
=============
This is a minor enhancement and bug-fix release. See the project website ( http://code.google.com/p/python-gnupg/ ) for more information. Summary:

An encoding bug which caused an exception when getting the GPG version has been fixed.
Recipients can be passed in a set or frozenset as well as in a list or tuple.
The keyring argument now accepts a list of public keyring filenames as well as a single filename.
A secret_keyring argument has been added which accepts either a single filename or a list of filenames for secret keyrings.

The current version passes all tests on Windows (CPython 2.4, 2.5, 2.6, 2.7, 3.1 and Jython 2.5.1), Mac OS X (Python 2.5) and Ubuntu (CPython 2.4, 2.5, 2.6, 2.7, 3.0, 3.1, 3.2). On Windows, GnuPG 1.4.11 has been used for the tests.

Eventlet 0.13 is going to have minor incompatible change insubprocess API

Sergey Shepelev — 2013-06-04T17:26:16

Hello.

I'm trying to reach out for as many Eventlet users as possible. This message contains specific actions to be taken by project owners to ensure compatibility with future versions of eventlet.

1. We're going to have a minor backward incompatible change. It will *only* affect you if you use Eventlet specific `check_interval` positional argument, e.g. subprocess.Popen(...).wait(0.1). Which is very unlikely, but I have to make sure. Checking will take less than minute best case.

2. Please run the following search against your code base:

grep -lr -E 'import.+subprocess' . |xargs grep -nE '\.wait\([^)]' |fgrep -v 'check_interval='

3. If you have any results on step 3, please check that either you imported subprocess from eventlet.green or used monkey_patch and matched lines correspond to eventlet.green.subprocess.Popen objects

4. If you have any results on step 4, that is, you pass check_interval as first positional argument to .wait() method of Popen object, please change it to keyword argument `check

Antonio Valentino — 2013-06-03T17:19:46

===========================
  Announcing PyTables 3.0.0
===========================

We are happy to announce PyTables 3.0.0.

PyTables 3.0.0 comes after about 5 years from the last major release
(2.0) and 7 months since the last stable release (2.4.0).

This is new major release and an important milestone for the PyTables 
project since it provides the long waited support for Python 3.x, which 
has been around for 4 years.

Almost all of the core numeric/scientific packages for Python already 
support Python 3 so we are very happy that now also PyTables can provide 
this important feature.


What's new
==========

A short summary of main new features:

- Since this release, PyTables now provides full support to Python 3
- The entire code base is now more compliant with coding style
   guidelines described in PEP8.
- Basic support for HDF5 drivers.  It now is possible to open/create an
   HDF5 file using one of the SEC2, DIRECT, LOG, WINDOWS, STDIO or CORE
   drivers.
- Basic support for in-memory image file

  * experimental support for QoS: ingress, sfq, tbf, htb, u32

A reasonable and well-documented QoS support is planned for 0.2.0, but 
one can start to play with it already now. Actually, the main goal of 
this project part is to get complete implementation of tcmsg, supported 
by modern kernels, and make it possible to manage qdisc-related stuff 
without external utilities (tc), directly communicating with the kernel.

iPOPO v0.5

Thomas Calmant — 2013-05-22T14:02:15

Hi all,

iPOPO is a service-oriented component model (SOCM) framework for Python, inspired from the Java project iPOJO.
It is separated in two parts:

* Pelix: a service-oriented architecture framework (SOA), which provides a
  registry of services and a life-cycle for modules.
* iPOPO: the SOCM, which handles the components

A component is an object with a life-cycle, requiring services and providing ones, and associated to properties. The code of a component is reduced to its functional purpose.
Life-cycle, dependencies, ... are handled by iPOPO.

This project provides utility services:
* a shell, to interact with the framework (console or remote)
* a HTTP service, to dynamically provide small servlets
* EventAdmin, a publish/subscribe communication service between components
* Remote services, to share services between Pelix frameworks

The project is released under the GPLv3 license, its source code is available on Github:
https://github.com/tcalmant/ipopo
