JyNI 2.7-alpha.3 released!
by Stefan Richthofer 16 Feb '16

16 Feb '16

Following up on the recent release of Jython 2.7.1 beta 3 I am proud to announce the release of JyNI 2.7-alpha.3. Take a look at jyni.org or go directly to the release: https://github.com/Stewori/JyNI/releases/tag/v2.7-alpha.3 Binaries are provided for target platforms JyNI is tested on. It should in principle be buildable/workable also on other posix platforms. Main new features are: * OS-X support * CPython-compatible garbage collection of native objects * capable of loading ctypes (core functionality tested) What comes next? ---------------- With this release I updated jyni.org/#roadmap; take a look to learn about plans for alpha.4, alpha.5 and beta.1. However, before I continue work toward alpha.4 I will check some Python frameworks that have ctypes-only native dependency for workability (e.g. PyOpenGL). Wish List --------- With this release I also introduce the Wish List section jyni.org/#wish-list. The intention of this list is to focus on actually *needed* API with priority before attempting exhaustive API support. If you have desire for a specific extension to work, send me a mail regarding jyni.org/#wish-list and I will check whether your extension is a "low hanging fruit" that can be supported via minor improvements. Especially extensions from the above mentioned category of ctypes-only-dependency highly qualify. Enjoy! -Stefan

[ANN] bzr 2.7.0 released
by Richard Wilbur 15 Feb '16

15 Feb '16

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 On behalf of the Bazaar team and community, I'm happy to announce availability of a new release of the bzr adaptive version control system. Bazaar <http://bazaar.canonical.com/> is a Canonical project and part of the GNU project <http://gnu.org/> to produce a free operating system. Thanks to everyone who contributed patches, suggestions, and feedback. Special thanks are due Vincent Ladeuil, without whom this release would not have made it out the door in time to be a part of the next Ubuntu Long-Term-Support release (16.04), and from whom I have been learning a great deal. Bazaar is now available for download from https://launchpad.net/bzr/2.7/2.7.0 as a source tarball. There is another source tarball that is nearly identical and equally valid (signed by the same developer) available on PyPI - the Python Package Index.[0] We used to point from PyPI to the source tarball on launchpad, but PyPI[1] now requires us to host any downloads locally. This requires an additional PKG-INFO file which is now part of our normal tarball creation process. Thus, from now on there will be no need for two tarballs. Volunteers are welcome to build a windows and an OSX installer. When those are created they will be available at the above link. Bazaar is also available for *BSD through the ports ecosystem at https://www.freshports.org/devel/bzr/ thanks to Matthew Fuller. This release marks the start of a new long-term-stable series. From here, we will only make bugfix releases on the 2.7 series (2.7.1, etc), while 2.8 will become our new development series. This is a bugfix release (20 bugs fixed) over the 2.6 series focusing on test issues triggered by various python 2.7 updates. All known fixed bugs are included here. Users are encouraged to upgrade from the other stable series. bzr 2.7 will be the last series with active python 2.6 testing and support. Python 2.6 hasn't received any updates since v2.6.9 of 29 Oct 2013. Python 2.7.9 of 10 Dec 2014 was the oldest version to receive a security fix with ssl library's match_hostname. See http://doc.bazaar.canonical.com/bzr.dev/en/release-notes/bzr-2.7.html for more details, Richard References: [0] https://pypi.python.org/pypi [1] https://www.python.org/dev/peps/pep-0470/ PEP 0470 -- Removing External Hosting Support on PyPI -----BEGIN PGP SIGNATURE----- Version: GnuPG v1 iEYEARECAAYFAlbB3NEACgkQp86zxxGv8LB2mACcCsQSWPY5y73koEqiTI/Bqq8r mVkAoKWs8pzvK7nmGcxgpzCEWA2oIEfr =ax6c -----END PGP SIGNATURE-----

EuroPython 2016: Sending out the first gravitational waves
by M.-A. Lemburg 15 Feb '16

15 Feb '16

We are pleased to announce the launch of our all new EuroPython 2016 website. Over the last few weeks, we have been busy talking to sponsors and getting the website prepared for the launch. You may have heard about the recent direct observation of gravitational waves by the LIGO (Laser Interferometer Gravitational-wave Observatory). What you may not know is that Python helped in analyzing the data, so we now have two things to celebrate: 1. Python’s use in this phenomenal direct proof of Einstein’s prediction and 2. the launch of our 2016 edition of the EuroPython conference. So here it is: *** https://ep2016.europython.eu/ *** July 17 - 24 2016 Many thanks go to our launch sponsors who have signed up early to give us that extra boost in motivation to get the conference and it’s website set up. Meet our Launch Sponsors ------------------------ * Bilbao Ekintza * Intel * UPV/EHU * Udemy * Python Software Foundation * Blue Yonder * Jet Brains * Numberly * Flying Circus * Limejump * RedHat * Vzzual.com * Django-CMS * Riverbank PS: We’d like to thank the EuroPython Web WG for the web site improvements and our friends at Python Italia for making their code available. With gravitational regards, -- EuroPython 2016 Team http://ep2016.europython.eu/ http://www.europython-society.org/

Sphinx 1.4-alpha1 released
by Takayuki Shimizukawa 14 Feb '16

14 Feb '16

Hi all, I'm very happy to announce the release of Sphinx 1.4-alpha1 available on the Python package index at <http://pypi.python.org/pypi/Sphinx/1.4a1>. This is the first testing release for Sphinx 1.4 that includes: * 31 features * 10 incompatible changes * 20 fixes of bugs/buglets from the 1.3.5 version of Sphinx For the full changelog, go to < http://www.sphinx-doc.org/en/master/changes.html>. Thanks to all coraborators and contributers! What's new in 1.4 (very short version)? ======================================= Features added -------------- * Directive: glossary term supports grouping key for index entries by using classifier syntax (experimental) * Directive: Support Imgmath (pngmath with svg support). * Builder: XeTeX and LuaTeX for the LaTeX builder. * Builder: Add the ``dummy`` builder: syntax check without output. * Builder: Add EPUB 3 builder (experimental) * Search: Chinese language search index. * Search: Japanese language search index by using Janome * Search: splitter customization for Japanese language search index * Domain: cpp domain improvements * Ext: Add sphinx.ext.githubpages to publish the docs on GitHub Pages * Ext: Add ``sphinx.ext.autosectionlabel`` extension to allow reference sections using its title. * API: Add Sphinx.add_source_parser() to add source_suffix and source_parsers from extension * Image recognition by using ``imagesize`` package w/o PIL/Pillow Incompatible changes -------------------- * sphinx_rtd_theme has become optional. Please install it manually. * :confval:`html_extra_path` also copies dotfiles in the extra directory, and refers to :confval:`exclude_patterns` to exclude extra files and directories. * Under glossary directive, each terms are converted into individual ``term`` nodes and ``termsep`` node is removed. By this change, output layout of every builders are changed a bit. * The default highlight language is now Python 3. This means that source code is highlighted as Python 3 (which is mostly a superset of Python 2), and no parsing is attempted to distinguish valid code. * `Locale Date Markup Language <http://unicode.org/reports/tr35/tr35-dates.html#Date_Format_Patterns>`_ like ``"MMMM dd, YYYY"`` is default forma for `today_fmt` and `html_last_updated_fmt`. However strftime format like ``"%B %d, %Y"`` is also supported for backward compatibility until Sphinx-1.5. Later format will be disabled from Sphinx-1.5. What is it? =========== Sphinx is a tool that makes it easy to create intelligent and beautiful documentation for Python projects (or other documents consisting of multiple reStructuredText source files). Website: http://sphinx-doc.org/ IRC: #sphinx-doc on irc.freenode.net Enjoy! -- Takayuki SHIMIZUKAWA http://about.me/shimizukawa

Eventlet 0.18.3 released
by Sergey Shepelev 13 Feb '16

13 Feb '16

Eventlet is a concurrent networking library for Python that allows you to change how you run your code, not how you write it. https://pypi.python.org/pypi/eventlet/0.18.3 The most scandal Eventlet release so far: https://pypi.python.org/pypi/eventlet/0.18.3 *Important note*: do not use versions 0.18.0 and 0.18.1, they contain known bug in wsgi on Python3. 0.18 line features Python3 compatible green.OpenSSL. Now important backward incompatible changes: - socket.send() will return fast, it no longer attempts to retry like sendall() which makes it consistent with Python standard library and removes a source of very subtle errors. - monkey patching removes things from `select` module, that we could not make green. This includes `select.poll()`, epoll, kqueue, etc. See full list here http://eventlet.net/doc/changelog.html the motivation here is that we want to prevent you from accidentally blocking whole process, while thinking it should all work together. Other goodies: * greenio: Fixed a bug that could cause send() to start an endless loop on ENOTCONN; Thanks to Seyeong Kim * wsgi: Fixed UNIX socket address being trimmed in "wsgi starting" log; Thanks to Ihar Hrachyshka * subprocess: Fixed missing subprocess.mswindows attribute on Python 3.5; Thanks to Josh VanderLinden * ssl/monkey patching: Fixed a bug that would cause merely importing eventlet to monkey patch the ssl module; Thanks to David Szotten * wsgi: Made the error raised in case of chunk read failures more precise (this should be backwards compatible as the new exception class, wsgi.ChunkReadError, is a subclass of ValueError which was being used there before); Thanks to Samuel Merritt * greenio: Fixed socket.recv() sometimes returning str instead of bytes on Python 3; Thanks to Janusz Harkot * websocket: Fixed TypeError on empty websocket message (Python 3); Thanks to Fukuchi Daisuke * greenio: Fixed handling blocking IO errors in various GreenSocket methods; Thanks to Victor Stinner * greenio: Fixed GreenPipe ignoring the bufsize parameter on Python 2; Thanks to Phus Lu * greenio: Made read() support buflen=-1 and added readall() (Python 3); Thanks to David Szotten * wsgi: Improved request body discarding * subprocess: Fixed universal_newlines support * wsgi: Output of 0-byte chunks is now suppressed; Thanks to Samuel Merritt Improved the documentation; Thanks to Ramakrishnan G, ashutosh-mishra and Azhar Hussain * greenio: Changed GreenFileIO.write() (Python 3) to always write all data to match the behavior on Python 2; Thanks to Victor Stinner documentation: Added support for building plain text documentation; thanks to Levente Polyak * backdoor: Added Unix and IPv6 socket support; Thanks to Eric Urban Our website: http://eventlet.net/ Direct package download links: https://pypi.python.org/packages/3.4/e/eventlet/eventlet-0.18.3-py2.py3-non… https://pypi.python.org/packages/source/e/eventlet/eventlet-0.18.3.tar.gz

[ANN] MicroPython 1.6
by Paul Sokolovsky 12 Feb '16

12 Feb '16

Hello, MicroPython is a lean and efficient Python implementation for microcontrollers, embedded, and mobile systems (which also runs just as fine on desktops, servers, and clouds). https://github.com/micropython/micropython https://github.com/micropython/micropython/releases/tag/v1.6 There're following major changes since 1.5: 1. LwIP module support for embedded TCP/IP networking. 2. IPv6 support in the Unix port. 3. Beta support for persistent bytecode (similar to CPython's .pyc) 4. 64-bit NaN boxing (improved floating-point performance if enabled). 5. Support for new official PyBoards PYBv1.1 and PYBLITEv1.0. 6. Long int constant folding during bytecode compilation (glad that CPython will catch up in that area thanks to FAT Python project). 7. There's a ongoing crowdfunding campaign to fund complete and well-maintained MicroPython port to ubiquitous ESP8266 WiFi SoC, and improve networking and IoT support in MicroPython in general: https://www.kickstarter.com/projects/214379695/micropython-on-the-esp8266-b… -- Best regards, Paul mailto:pmiscml@gmail.com
