Microsoft Visual C++ Compiler for Python 2.7
by Steve Dower 30 Sep '14

30 Sep '14

Microsoft has released a compiler package for Python 2.7 to make it easier for people to build and distribute their C extension modules on Windows. The Microsoft Visual C++ Compiler for Python 2.7 is available from: http://aka.ms/vcpython27 This package contains all the tools and headers required to build C extension modules for Python 2.7 32-bit and 64-bit (note that some extension modules require 3rd party dependencies such as OpenSSL or libxml2 that are not included). Other versions of Python built with Visual C++ 2008 are also supported. You can install the package without requiring administrative privileges and, with the latest version of setuptools, use tools such as pip, wheel, or a setup.py file to produce binaries on Windows. (Note: This version of Visual C++ is no longer supported by Microsoft, and so new features, support, or bug fixes are not available.)

________________________________________________________________________ ANNOUNCING eGenix PyCon UK 2014 Talks & Videos This announcement is also available on our web-site for online reading: http://www.egenix.com/company/news/PyCon-UK-2014-Presentations.html ________________________________________________________________________ We have just published the talk slides and videos of our PyCon UK 2014 presentations. The PyCon UK Conference is the premier conference for Python users and developers in the UK. This year it was held from September 19-22 in Coventry, UK. ________________________________________________________________________ EGENIX TALKS AT PYCON UK 2014 At this year's PyCon UK, Marc-André Lemburg, CEO of eGenix, gave the following talks at the conference. The presentations are available for viewing and download from our Presentations and Talks section: http://www.egenix.com/library/presentations/ When performance matters ... ---------------------------- Simple idioms you can use to make your Python code run faster and use less memory. Python applications sometimes need all the performance they can get. Think of e.g. web, REST or RPC servers. There are several ways to address this: scale up by using more processes, use Cython, use PyPy, rewrite parts in C, etc. However, there are also quite a few things that can be done directly in Python. This talk goes through a number of examples and show cases how sticking to a few idioms can easily enhance the performance of your existing applications without having to revert to more complex optimization strategies. The talk was complemented with a lightning talk titled "Pythons and Flies", which addresses a memory performance idiom and answers one of the audience questions raised in the above talk. Talk video and slides: http://www.egenix.com/library/presentations/PyCon-UK-2014-When-performance-… Python Web Installer -------------------- Installing Python packages is usually done with one of the available package installation systems, e.g. pip, easy_install, zc.buildout, or manually by running "python setup.py install" in a package distribution directory. These systems work fine as long as you have Python-only packages. For packages that contain binaries, such as Python C extensions or other platform dependent code, the situation is a lot less bright. In this talk, we present a new web installer system that we're currently developing to overcome these limitations. The system combines the dynamic Python installation interface supported by all installers ("python setup.py install"), with a web installer which automatically selects, downloads, verifies and installs the binary package for your platform. Talk video and slides: http://www.egenix.com/library/presentations/PyCon-UK-2014-Python-Web-Instal… If you are interested in learning more about these idioms and techniques, eGenix now offers Python project coaching and consulting services to give your project teams advice on how to achieve best performance and efficiency with Python: http://www.egenix.com/services/coaching/ Please contact our eGenix Sales Team for information: sales(a)egenix.com. ________________________________________________________________________ INFORMATION About Python (http://www.python.org/): Python is an object-oriented Open Source programming language which runs on all modern platforms.

A pair of desktop utilities: calendar, folder merge
by Mark Lutz 28 Sep '14

28 Sep '14

A pair of basic tkinter desktop utility programs that others may find useful: 1) frigcal -- a "refrigerator" style calendar desktop GUI 2) mergeall -- do-it-yourself "cloud" storage, script + GUI Both were coded in part as supplements for book readers, but have grown useful enough to merit a wider post and broader user testing. Feedback welcome; details follow. ------------------------------------------------------------------------ 1) frigcal -- a "refrigerator" style calendar desktop GUI Documentation: http://learning-python.com/README-frigcal.html Download: http://learning-python.com/frigcal.zip Screenshots: http://learning-python.com/screenshots/01-win7-main-window.png http://learning-python.com/screenshots/02-win7-clones-and-images.png http://learning-python.com/screenshots/ A Python 3.X program that implements a basic personal calendar GUI. It uses portable iCalendar files for event storage, and sports Python coded configuration, persistent events, event colorization, multiple calendar files, multiple month windows, and automatic calendar backups. This program is not an Outlook replacement: it does not implement tools such as task scheduling, journaling, alarms, invitations, or recurring or multiday events. In exchange for its limited utility, though, this program minimizes code and GUI complexity; reduces the risk of data loss; and yields a calendar sufficient for most personal needs, that requires neither a subscription nor an account log-in. ------------------------------------------------------------------------ 2) mergeall -- do-it-yourself "cloud" storage, script + GUI Documentation: http://www.rmi.net/~lutz/mergeall.html Download: http://www.rmi.net/~lutz/mergeall.zip Screenshots: http://www.rmi.net/~lutz/launch-mergeall-GUI-screenshot-main.png http://www.rmi.net/~lutz/mergeall-desktop-screenshot-tablet.png http://www.rmi.net/~lutz/mergeall-desktop-screenshot-linux.png A Python 3.X/2.X script and GUI useful for managing backups and changes in multiple copies of large directory trees (folders). Designed to quickly synchronize changes in content mirrored across multiple devices such as laptops, tablets, and USB flashdrives, this program in some contexts can provide a manual alternative to cloud-based storage. Directory tree synchronization isn't the same as a "cloud," of course; but together with fast local storage devices, this program might just help you avoid paying to store your personal data at sites that may share it with, or sell it to, both advertisers and government agencies (who, shockingly, may not have your best interest at heart). ------------------------------------------------------------------------ Cheers, --Mark Lutz (http://learning-python.com, http://www.rmi.net/~lutz)

mds-utils 2.1.0 released
by Michele De Stefano 28 Sep '14

28 Sep '14

I am pleased to announce the release of mds-utils 2.1.0 <http://www.micheledestefano.joomlafree.it/en/mds-utils.html>. Features summary --------------------------- MDS-UTILS provides: 1. a tool for detecting machine endianity. 2. utilities for the Boost uBLAS library. Amongst them, some type traits for detecting different uBLAS matrix types. 3. some useful classes that allow to treat the old C FILE pointer as a C++ stream. 4. C++ wrappers of the main Python objects, independent of those in Boost Python. Wrappers are provided also for NumPy arrays. 5. C++ classes that help on treating Python file objects as C++ streams. 6. a review and refactor of the indexing support in Python extensions. Now access in write mode is supported too. 7. new C++ *to-Python* and *from-Python* converters for some *Boost uBlas* objects and for standard Python objects. These converters do not depend on Boost Python. 8. a new sequence iterator that is able to wrap Python sequences and allows also to modify them. This feature does not depend on Boost.Python. 9. the NDArrayIterator class, that wraps the Numpy C-API iterator and allows easy management of conversions to/from Numpy arrays. 10. some SWIG interface files, for easy integration with SWIG extensions for Python. Each class is a well-documented, small, easy to use and it should never be too difficult to learn to use it. A large percentage of this library makes a heavy usage of the Boost C++ libraries <http://www.boost.org/>: so, they must be installed on the system. It is assumed that the user is familiar with them.

TextTest 3.27 - blackbox testing tool
by Geoff Bache 26 Sep '14

26 Sep '14

Dear all, The latest release of TextTest includes - Support for parallel testing using EC2 cloud - Packaging and release process should now be smoother - Now integrates with Git as well and bzr and hg. - Performance data in HTML reports overhauled and many other things besides. Regards, Geoff Bache .... TextTest is a tool for automatic text-based functional testing. This means running a batch-mode executable in lots of different ways from the command line, and using the text output produced as a means of controlling the behavior of that application. As well as being usable "standalone", it is an extendable framework for black-box testing written in Python. It's also useful as a test management tool wrapping some other test tool as a test runner.

PyGObject provides a convenient wrapper for use in Python programs when accessing GObject libraries. Like the GObject library itself PyGObject is licensed under the GNU LGPL, so is suitable for use in both free software and proprietary applications. It is already in use in many applications ranging from small single purpose scripts up to large full featured applications. PyGObject now dynamically accesses any GObject libraries that uses GObject Introspection. It replaces the need for separate modules such as PyGTK, GIO and python-gnome to build a full GNOME 3.0 application. Once new functionality is added to gobject library it is instantly available as a Python API without the need for intermediate Python glue.

devpi-{server-2.1,web-2.2}: upload history, deploy status, groups
by holger krekel 22 Sep '14

22 Sep '14

devpi-{server-2.1,web-2.2}: upload history, deploy status, groups ================================================================== With devpi-server-2.1 and devpi-web-2.2 you'll get a host of fixes and improvements as well as some major new features for the private pypi system: - upload history: release/tests/doc files now carry metadata for by whom, when and to which index something was uploaded - deployment status: the new json /+status gives detailed information about a replica or master's internal state - a new authentication hook supports arbitrary external authentication systems which can also return "group" membership information. An initial separately released "devpi-ldap" plugin implements verification accordingly. You can specify groups in ACLs with the ":GROUPNAME" syntax. - a new "--restrict-modify=ACL" option to start devpi-server such that only select accounts can create new or modify users or indexes For many more changes and fixes, please see the CHANGELOG information below. UPGRADE note: devpi-server-2.1 requires to ``--export`` your 2.0 server state and then using ``--import`` with the new version before you can serve your private packages through devpi-server-2.1. Please checkout the web plugin if you want to have a web interface:: http://doc.devpi.net/2.1/web.html Here is a Quickstart tutorial for efficient pypi-mirroring on your laptop:: http://doc.devpi.net/2.1/quickstart-pypimirror.html And if you want to manage your releases or implement staging as an individual or within an organisation:: http://doc.devpi.net/2.1/quickstart-releaseprocess.html If you want to host a devpi-server installation with nginx/supervisor and access it from clients from different hosts:: http://doc.devpi.net/2.1/quickstart-server.html More documentation here:: http://doc.devpi.net/2.1/ many thanks to Florian Schulze who co-implemented many of the new features. And special thanks go to the two companies who funded major parts of the above work. have fun, Holger Krekel, merlinux GmbH devpi-server-2.1.0 (compared to 2.0.6) ---------------------------------------- - make replication more precise: if a file cannot be replicated, fail with an error log and try again in a few seconds. This helps to maintain a consistent replica and discover the potential remaining bugs in the replication code. - add who/when metadata to release files, doczips and test results and preserve it during push operations so that any such file provides some history which can be visualized via the web-plugin. The metadata is also exposed via the json API (/USER/INDEX/PROJECTNAME[/VERSION]) - fix issue113: provide json status information at /+status including roles and replica polling status, UUIDs of the repository. See new server status docs for more info. - support for external authentication plugins: new devpiserver_auth_user hook which plugins can implement for user/password validation and for providing group membership. - support groups for acl_upload via the ":GROUPNAME" syntax. This requires an external authentication plugin that provides group information. - on replicas return auth status for "+api" requests by relaying to the master instead of using own key. - add "--restrict-modify" option to specify users/groups which can create, delete and modify users and indices. - make master/replica configuration more permanent and a bit safer against accidental errors: introduce "--role=auto" option, defaulting to determine the role from a previous invocation or the presence of the "--master-url" option if there was no previous invocation. Also verify that a replica talks to the same master UUID as with previous requests. - replaced hack from nginx template which abused "try_files" in "location /" with the recommended "error_page"/"return" combo. Thanks Jürgen Hermann - change command line option "--master" to "--master-url" - fix issue97: remove already deprecated --upgrade option in favor of just using --export/--import - actually store UTC in last_modified attribute of release files instead of the local time disguising as UTC. preserve last_modified when pushing a release. - fix exception when a static resource can't be found. - address issue152: return a proper 400 "not registered" message instead of 500 when a doczip is uploaded without prior registration. - add OSX/launchd example configuration when "--gen-config" is issued. thanks Sean Fisk. - fix replica proxying: don't pass original host header when relaying a modifying request from replica to master. - fix export error when a private project doesnt exist on pypi - fix pushing of a release when it contains multiple tox results. - fix "refresh" button on simple pages on replica sites - fix an internal link code issue possibly affecting strangeness or exceptions with test result links - be more tolerant when different indexes have different project names all mapping to the same canonical project name. - fix issue161: allow "{pkgversion}" to be part of a jenkins url devpi-web-2.2.0 (compared to 2.1.6) ---------------------------------------- - require devpi-server >= 2.1.0 - static resources now have a plus in front to avoid clashes with usernames and be consistent with how other urls work: "+static/..." and "+theme-static/..." - adjusted font-sizes and cut-off width of content. - only show underline on links when hovering. - make the "description hasn't been rendered" warning stand out. - version.pt: moved md5 sum from it's own column to the file column below the download link - version.pt: added "history" column showing last modified time and infos about uploads and pushes. - fix issue153: friendly error messages on upstream errors. - index.pt: show permissions on index page devpi-client-2.0.3 (compared to 2.0.2) ---------------------------------------- - use default "https://www.python.org/pypi" when no repository is set in .pypirc see https://docs.python.org/2/distutils/packageindex.html#the-pypirc-file - fix issue152: when --upload-docs is given, make sure to first register and upload the release file before attempting to upload docs (the latter requires prior registration) - fix issue75: add info about basic auth to "url" option help of "devpi use". - fix issue154: fix handling of vcs-exporting when unicode filenames are present. This is done by striking our own code in favor of Marius Gedminas' vcs exporting functions from his check-manifest project which devpi-client now depends on. This also adds in support for svn and bazaar in addition to the already supported git/hg. - devpi list: if a tox result does not contain basic information (probably a bug in tox) show a red error instead of crashing out with a traceback. - fix issue157: filtering of tox results started with the oldest ones and didn't show newer results if the host, platform and environment were the same.

21 Sep '14

Lea, discrete probability distributions in Python ================================================= I have the pleasure to announce the release of Lea 1.3.1. NEW: Lea now runs on Python 3 (and still on Python 2.x) ! Lea is a Python package that allows you to define and play with discrete probability distributions in an intuitive way. Lea can model a broad range of random discrete phenomenons. Then, it allows calculating probabilities of events, whether atomic, aggregated or combined through operations. A typical example is the probabilities of the sum of N dice having known, possibly unfair, probability distributions. Download (PyPi) =============== <http://pypi.python.org/pypi/lea> http://pypi.python.org/pypi/lea Project page / documentation ============================ <http://code.google.com/p/lea/> http://code.google.com/p/lea/ Features ======== - models finite discrete probability distributions - standard distribution indicators (mean, standard deviation,.) - arithmetic and logical operators on probability distribution - cartesian products, conditional probabilities, joint distributions - generation of random samples - open-source project, LGPL license - runs on Python 2.x and 3.x - pure Python module, lightweight - no package dependency - probabilities stored as rationals (no floating-point biases) Hoping Lea could be helpful in this uncertain universe...

pytest-xdist-1.11: restarting crash nodes, fixture cache fix
by holger krekel 18 Sep '14

18 Sep '14

I just released pytest-xdist-1.11, the distributed testing plugin for pytest. It introduces automatic restarting of crashed nodes, courtesy of a complete PR from Floris Bruynooghe. This also works well together with pytest-timeout by the same author: When one or more test functions hang or crash, the overall test run will still complete and report about the incidents. See the changelog below for more changes and the pypi project page for what pytest-xdist offers in general: https://pypi.python.org/pypi/pytest-xdist/ Thanks also to an undisclosed company who partly funded the work and to Andreas Pelme for contributing analysis of a fixture caching failure including a test. best, Holger Krekel 1.11 ------------------------- - fix pytest/xdist issue485 (also depends on py-1.4.22): attach stdout/stderr on --boxed processes that die. - fix pytest/xdist issue503: make sure that a node has usually two items to execute to avoid scoped fixtures to be torn down pre-maturely (fixture teardown/setup is "nextitem" sensitive). Thanks to Andreas Pelme for bug analysis and failing test. - restart crashed nodes by internally refactoring setup handling of nodes. Also includes better code documentation. Many thanks to Floris Bruynooghe for the complete PR.

ANN: wxPython 3.0.1.1
by Robin Dunn 12 Sep '14

12 Sep '14

Announcing ---------- wxPython 3.0.1.1 (classic) has been released and is now available for download at http://wxpython.org/download.php. This build adds some updates of the 3rdParty libraries that were left out of the last build by mistake. Various binaries are available for 32-bit and 64-bit Windows, and also for OSX using the Carbon and Cocoa APIs, for Python 2.6 and 2.7. Source code is also available at http://wxpython.org/download.php of course, for building your own. What is wxPython? ----------------- wxPython is a GUI toolkit for the Python programming language. It allows Python programmers to create programs with a robust, highly functional graphical user interface, simply and easily. It is implemented as a set of Python extension modules that wrap the GUI components of the popular wxWidgets cross platform library, which is written in C++. wxPython is a cross-platform toolkit. This means that the same program will usually run on multiple platforms without modifications. Currently supported platforms are 32-bit and 64-bit Microsoft Windows, most Linux or other Unix-like systems using GTK2, and Mac OS X 10.4+. In most cases the native widgets are used on each platform to provide a 100% native look and feel for the application. -- Robin Dunn Software Craftsman http://wxPython.org

ANN: Bokeh 0.6 release
by Bryan Van de Ven 10 Sep '14

10 Sep '14

On behalf of the Bokeh team, I am very happy to announce the release of Bokeh version 0.6! Bokeh is a Python library for visualizing large and realtime datasets on the web. Its goal is to provide to developers (and domain experts) with capabilities to easily create novel and powerful visualizations that extract insight from local or remote (possibly large) data sets, and to easily publish those visualization to the web for others to explore and interact with. This release includes many bug fixes and improvements over our most recent 0.5.2 release: * Abstract Rendering recipes for large data sets: isocontour, heatmap * New charts in bokeh.charts: Time Series and Categorical Heatmap * Full Python 3 support for bokeh-server * Much expanded User and Dev Guides * Multiple axes and ranges capability * Plot object graph query interface * Hit-testing (hover tool support) for patch glyphs See the CHANGELOG for full details. I'd also like to announce a new Github Organization for Bokeh: https://github.com/bokeh. Currently it is home to Scala and and Julia language bindings for Bokeh, but the Bokeh project itself will be moved there before the next 0.7 release. Any implementors of new language bindings who are interested in hosting your project under this organization are encouraged to contact us. In upcoming releases, you should expect to see more new layout capabilities (colorbar axes, better grid plots and improved annotations), additional tools, even more widgets and more charts, R language bindings, Blaze integration and cloud hosting for Bokeh apps. Don't forget to check out the full documentation, interactive gallery, and tutorial at http://bokeh.pydata.org as well as the Bokeh IPython notebook nbviewer index (including all the tutorials) at: http://nbviewer.ipython.org/github/ContinuumIO/bokeh-notebooks/blob/master/… If you are using Anaconda, you can install with conda: conda install bokeh Alternatively, you can install with pip: pip install bokeh BokehJS is also available by CDN for use in standalone javascript applications: http://cdn.pydata.org/bokeh-0.6.min.js http://cdn.pydata.org/bokeh-0.6.min.css Issues, enhancement requests, and pull requests can be made on the Bokeh Github page: https://github.com/continuumio/bokeh Questions can be directed to the Bokeh mailing list: bokeh(a)continuum.io If you have interest in helping to develop Bokeh, please get involved!

ANN: wxPython 3.0.1.0 release
by Robin Dunn 08 Sep '14

08 Sep '14

Announcing ---------- wxPython 3.0.1.0 (classic) has been released and is now available for download at http://wxpython.org/download.php. (Finally! Sorry, but life and work has kept me busy.) No new features to speak of, but there has been lots of bug fixes in wxWidgets and a few on the wxPython side too. Various binaries are available for 32-bit and 64-bit Windows, and also for OSX using the Carbon and Cocoa APIs, for Python 2.6 and 2.7. Source code is also available at http://wxpython.org/download.php of course, for building your own. What is wxPython? ----------------- wxPython is a GUI toolkit for the Python programming language. It allows Python programmers to create programs with a robust, highly functional graphical user interface, simply and easily. It is implemented as a set of Python extension modules that wrap the GUI components of the popular wxWidgets cross platform library, which is written in C++. wxPython is a cross-platform toolkit. This means that the same program will usually run on multiple platforms without modifications. Currently supported platforms are 32-bit and 64-bit Microsoft Windows, most Linux or other Unix-like systems using GTK2, and Mac OS X 10.4+. In most cases the native widgets are used on each platform to provide a 100% native look and feel for the application. -- Robin Dunn Software Craftsman http://wxPython.org

Vulture 0.6 released
by Jendrik Seipp 07 Sep '14

07 Sep '14

vulture - Find dead code ======================== vulture finds unused classes, functions and variables in Python code. This helps you cleanup and find errors in your programs. If you run it on both your library and test suite you can find untested code. Due to Python's dynamic nature it is impossible to find all dead code for a static code analyzer like vulture, because it ignores scopes and scans only token names. Additionally some dynamic items that are not explicitly mentioned in the code may be incorrectly reported as dead code. Download ======== http://pypi.python.org/pypi/vulture Features ======== - Fast: Uses static code analysis - Lightweight: Only one module - Complements pyflakes and has the same output syntax - Supports Python 2.6, 2.7 and 3.x News ==== * Ignore function names starting with "test_". * Parse variable names in new format strings (e.g. "This is {x}".format(x="nice")). * Only parse alphanumeric variable names in format strings and ignore types. * Abort with exit code 1 on syntax errors. * Support installation under Windows by using setuptools (thanks Reuben Fletcher-Costin). Cheers, Jendrik

prophy 0.4.2 - fast serialization protocol
by Krzysztof Laskowski 07 Sep '14

07 Sep '14

Hello, I'd like to announce Prophy, the serialization protocol. It has a schema language and compiler generating codecs for Python and C++. It's aimed to provide tools similar to Google Protobuf to handle messages of XDR-like wire format: no tags, unpacked ints, padding for alignment. Reason for starting up the project when so many outstanding serialization protocols exist is the simplicity of native binary wire format. Prophy lets severely restricted embedded environments to encode messages efficiently (in-place) and allows acceptance tests and cooperating devices to use automatic but more resource-hungry codecs. License: MIT PyPI: https://pypi.python.org/pypi/prophy/0.4.2 Documentation: http://prophy.readthedocs.org Github: https://github.com/aurzenligl/prophy Email: krzysztof.laskowski.1986(a)gmail.com Current release is 0.4.2. Before 1.0 I plan to do: - Python 3 support, - full C++ codec (structs and unions with vectors instead of arrays and generated encode, decode, print methods), - language enhancements (includes, inner definitions, bool, string). Feel free to provide feedback. Best Regards, Krzysztof Laskowski

Polly - Python program to generate XKCD 936 passwords from your email
by Skip Montanaro 06 Sep '14

06 Sep '14

Based on a discussion on comp.lang.python, I stole an idea from Chris Angelico. His D&D game has a parrot that listens to the chatter of the participants. You can ask Polly for a password and it will spit out an XKCD 936 password from the words it has seen. I don't play D&D, but I get a ton of mail from public mailing lists and Internet forums, so I figured I could use that stream of messages as a word set. In deference to Chris, I named it Polly. Polly is written in Python and uses imaplib to monitor an IMAP folder for messages. It seems stable enough at this point that mentioning it outside of other threads on comp.lang.python seems useful. I have no official release, just a Github repository: https://github.com/smontanaro/polly Feel free to fork it and play around. I've never used imaplib for anything, and figure that code code could use a bit of help. Skip

devpi-server-2.0.4 hotfix for pypi.python.org change
by holger krekel 01 Sep '14

01 Sep '14

devpi-server-2.0.4 is a hotfix release to adapt to a pypi.python.org change from three days ago which would cause devpi to fail installations for packages like "Sphinx", "Django" ... because pypi now serves them under their canonical name instead of the registered one. As usual, docs for the devpi system are at http://doc.devpi.net best and have fun, Holger Krekel, merlinux GmbH devpi-server 2.0.4 -------------------- - fix issue139: adapt to a recent change in pypi which now serves under URLs using normalized project names instead of the "real" registered name Thanks Timothy Allen and others for sorting this out. - fix issue129: fix __init__ provided version and add a test that it always matches the one which pkg_resources sees (which gets it effectively from setup.py)
