ANN: pyftpdlib 1.5.0 released
by Giampaolo Rodola' 13 Dec '15

13 Dec '15

Hi there guys, I'm pleased to announce pyftpdlib 1.5.0 release. About ===== Python FTP server library provides a high-level portable interface to easily write very efficient and scalable asynchronous FTP servers with Python. It is the most complete RFC-959<http://www.faqs.org/rfcs/rfc959.html> FTP server implementation available for Python <http://www.python.org/> programming language. Main enhancements =============== - Many bugfixes against the SSL implementation. - #365: FTPS (FTP over SSL) is now 25% faster when dealing with clear-text connections. - #340: dropped python 2.4 and 2.5 support. - #344: SSL support for benchmark script. - #351: fallback on using plain send() if sendfile() fails and no data has been transmitted yet. - #356: sendfile() is now used in case we're using SSL but data connection is in clear text. Links ===== Home: https://github.com/giampaolo/pyftpdlib Docs: https://pythonhosted.org/pyftpdlib/ Mailing list: https://groups.google.com/forum/#!forum/pyftpdlib Changes: https://github.com/giampaolo/pyftpdlib/blob/master/HISTORY.rst Thanks -- Giampaolo - http://grodola.blogspot.com

poliastro 0.4, Astrodynamics in Python
by Juan Luis Cano 13 Dec '15

13 Dec '15

Hello all, I am very pleased to announce poliastro 0.4.0, a MIT licensed, pure Python library for studying Orbital Mechanics and Astrodynamics problems! https://poliastro.github.io/ This release several new features: * Angle conversion functions * Equinoctial elements * Numerical propagation * Python 3.5 and NumPy 1.10 compatibility You can install it using either pip or conda: $ pip install poliastro $ conda install poliastro --channel poliastro If you want to see an overview of poliastro capabilities, check out this IPython notebook describing how to plot the trajectory of rover Curiosity to Mars: http://nbviewer.ipython.org/github/poliastro/poliastro/blob/0.4.x/examples/… poliastro is an open source collection of Python subroutines for solving problems in Astrodynamics and Orbital Mechanics. It combines cutting edge technologies like Python JIT compiling (using numba) with young, well developed astronomy packages (like astropy and jplephem) to provide a user friendly API for solving Astrodynamics problems. It is therefore a experiment to mix the best Python open source practices with my love for Orbital Mechanics. The User Guide explains the basic use of the library and examples are provided in the form of IPython notebooks. See the "What's new" document and the GitHub log for a complete list of changes. https://poliastro.github.io/changelog.html#new-in-poliastro-0-4-0 The project is still a work in progress and the codebase is subject to change. Contributions, bug reports, suggestions and advice are more than welcome! https://github.com/poliastro/poliastro/issues Best regards, Juan Luis Cano

PyMailGUI standalone release
by Mark Lutz 11 Dec '15

11 Dec '15

There is a new standalone release of PyMailGUI - a POP/SMTP email client which is a major example in a large Python book (shameless plug omitted). This release's code is identical to that in the book, but has a different launcher and a self-contained package structure for standalone use. PyMailGUI is a bit limited because it was written for use as a teaching tool in a book. On the other hand, it does threading, MIME attachments, Unicode, and more, and is useful enough to have served as its author's primary email tool for over a decade. It may also reduce the probability of your email being read by a giant evil company without your consent. Screenshot: http://learning-python.com/pymailgui/screenshots/main-standalone.png Docs: http://learning-python.com/pymailgui/Readme-PyMailGUI.html Code: http://learning-python.com/pymailgui/ Fetch: http://learning-python.com/downloads/ Cheers, --M.

tox-2.3.0: bug fixes, new plugin hooks
by holger krekel 11 Dec '15

11 Dec '15

Just released tox-2.3.0, the python test configuration and automation tool. It brings some important bug fixes and more hooks related to testenvironment creation and installation, allowing upcoming plugins like tox-debian to add extra steps during installation. I'd like to send special thanks to the Tryton foundation who organized some funding in order to tackle the proper fixing of a serious regression of tox-2.2 (see changelog below). thanks also to David Stanek, Julien Castets, Nelfin for their contributions. You'll find the current docs for tox here: https://testrun.org/tox/latest/ and have fun, holger krekel -- about me: http://holgerkrekel.net/about-me/ contracting: http://merlinux.eu 2.3.0 ----- - DEPRECATE use of "indexservers" in tox.ini. It complicates the internal code and it is recommended to rather use the devpi system for managing indexes for pip. - fix issue285: make setenv processing fully lazy to fix regressions of tox-2.2.X and so that we can now have testenv attributes like "basepython" depend on environment variables that are set in a setenv section. Thanks Nelfin for some tests and initial work on a PR. - allow "#" in commands. This is slightly incompatible with commands sections that used a comment after a "\" line continuation. Thanks David Stanek for the PR. - fix issue289: fix build_sphinx target, thanks Barry Warsaw. - fix issue252: allow environment names with special characters. Thanks Julien Castets for initial PR and patience. - introduce experimental tox_testenv_create(venv, action) and tox_testenv_install_deps(venv, action) hooks to allow plugins to do additional work on creation or installing deps. These hooks are experimental mainly because of the involved "venv" and session objects whose current public API is not fully guranteed. - internal: push some optional object creation into tests because tox core doesn't need it.

Pylint and Pylint's Astroid projects moved to the Python Code-Quality Authority
by Ian Cordasco 10 Dec '15

10 Dec '15

Hi everyone! It's my pleasure to announce to you that PyLint and its Astroid library have migrated to git from mercurial and have migrated from BitBucket to the Python Code-Quality Authority (PyCQA) organization on GitHub. The new URLs are: - PyLint: https://github.com/pycqa/pylint - Astroid: https://github.com/pycqa/astroid For those who do not know, Pylint (http://www.pylint.org/) is a Python source code analyzer which looks for programming errors, helps enforcing a coding standard and sniffs for some code smells. Astroid provides a common base representation of python source code for projects such as pychecker, pyreverse, pylint. Cheers, Ian PyCQA Administrator Flake8, mccabe, pep8, and pyflakes core developer

ANN: Cpyx 0.2
by David N. Mashburn 09 Dec '15

09 Dec '15

Announcing Cpyx version 0.2 Github: https://github.com/davidmashburn/cpyx Bitbucket: https://bitbucket.org/davidmashburn/cpyx PyPI: https://pypi.python.org/pypi/Cpyx Cpyx is a utility to automatically build C and Cython code using either distutils or command line cython and gcc. Numpy is supported in both cases. The two core functions are cc and cpyx which compile c sources and cython+c sources respecively. * "cc" builds a shared library from all included inputs, using path resolution and quoting to aid in debugging issues (gcc commands should run verbatim from any directory). * "cpyx" builds multiple c and cython sources into a python extension module. Cpyx is quite simple (the main two functions are only ~100 lines of code), so it is easy to fiddle with. Example usage: import Cpyx Cpyx.cpyx('some_file.pyx', ['one_file.c', 'another_file.c']) Complete examples can be found here: https://github.com/davidmashburn/Cpyx/tree/master/examples NEW IN VERSION 0.2: *All functions were significantly overhauled and function names were changed* (old Cdll and Cpyx/CpyxLib became "cc" and "cpyx" respectively). Support for inlined cython code has been dropped since cython now supports this automatically using "cython.inline". New helpful utilities for extracting C function information (i.e. to generate code using templates): * get_function_raw_arguments -- Get all arguments as a single string (everything inside the parentheses) * get_function_args -- Get a string for each argument * get_function_types_and_variables -- Get a list of [type, variable] for each argument * rebuild_function_signature -- Get a well-formatted version of the full function signature Ideally, Cpyx should work anywhere gcc, cython, and python/numpy are installed. The 0.1 branch was relatively well-tested and worked on Windows (XP/Vista/7), Linux (Ubuntu), and Mac OS X (Leopard/Snow Leopard). The 0.2 branch has been pretty thoroughly tested on Ubuntu Linux, but let me know if it does not work for you on any OS. distutils may or may not work on Windows with mingw I know there are other tools out there (most notably pyximport and sage's misc/cython.py) to do this same kind of thing (and in much cooler ways). But Cpyx scratches my itch, so I thought I'd put it out there. Happy Cythoning! This project supports work that I did at Vanderbilt University and am doing at Pluralsight, LLC. Cheers! -David Mashburn <P><A HREF="https://github.com/davidmashburn/cpyx">Cpyx 0.2</A> - A gcc/cython/distutils wrapper for compiling Cython and C code directly from python. (10-Dec-15)
