CFFI 1.0.1 released
by Armin Rigo 21 May '15

21 May '15

Hi all, CFFI 1.0.1 final has now been released for CPython! CFFI is a (CPython and PyPy) module to interact with C code from Python. The main news from CFFI 0.9 is the new way to build extension modules: the "out-of-line" mode, where you have a separate build script. When this script is executed, it produces the extension module. This comes with associated Setuptools support that fixes the headache of distributing your own CFFI-using packages. It also massively cuts down the import times.

pytest-2.7.1: bugfix release, wheel support, yield fixtures
by Floris Bruynooghe 19 May '15

19 May '15

pytest-2.7.1: bugfix release, wheel support and yield fixtures ============================================================== pytest is a mature Python testing tool with more than a 1100 tests against itself, passing on many different interpreters and platforms. This release is supposed to be drop-in compatible to 2.7.0. The most user-visible changes are that wheels are now available on pypi and yield fixtures are no longer marked as experimental, they are here to stay. See below for the changes and see docs at: http://pytest.org As usual, you can upgrade from pypi via:: pip install -U pytest Thanks to all who contributed to this release, among them: Bruno Oliveira Holger Krekel Ionel Maries Cristian Floris Bruynooghe Happy testing, The py.test Development Team 2.7.1 (compared to 2.7.0) ------------------------- - fix issue731: do not get confused by the braces which may be present and unbalanced in an object's repr while collapsing False explanations. Thanks Carl Meyer for the report and test case. - fix issue553: properly handling inspect.getsourcelines failures in FixtureLookupError which would lead to to an internal error, obfuscating the original problem. Thanks talljosh for initial diagnose/patch and Bruno Oliveira for final patch. - fix issue660: properly report scope-mismatch-access errors independently from ordering of fixture arguments. Also avoid the pytest internal traceback which does not provide information to the user. Thanks Holger Krekel. - streamlined and documented release process. Also all versions (in setup.py and documentation generation) are now read from _pytest/__init__.py. Thanks Holger Krekel. - fixed docs to remove the notion that yield-fixtures are experimental. They are here to stay :) Thanks Bruno Oliveira. - Support building wheels by using environment markers for the requirements. Thanks Ionel Maries Cristian. - fixed regression to 2.6.4 which surfaced e.g. in lost stdout capture printing when tests raised SystemExit. Thanks Holger Krekel. - reintroduced _pytest fixture of the pytester plugin which is used at least by pytest-xdist.

Trac 1.1.5 Released
by Ryan Ollos 18 May '15

18 May '15

Trac 1.1.5 Released =================== Trac 1.1.5 continues the 1.1.x development line leading to 1.2 with some new features and a few not-so-disruptive changes. Note that the 1.1.x releases are "stable" and tested snapshots of the trunk. They can be seen as sub-milestones on the road towards Trac 1.2. As opposed to maintenance releases, *we offer no guarantees on feature and API compatibility from one 1.1.x release to the next*. However, by following 1.1.x you get a chance to use new features earlier, and therefore be able to contribute feedback when things are still in flux. It's also less risky than just getting the latest trunk, as we won't cut a 1.1.x release in the middle of a series of changes (though we had and still intend to have a good record of keeping things always working on trunk). The intended audience are therefore enthusiast Trac users and Trac plugin developers. These packages should *not* be integrated in distributions, for example. Here are a few highlights: - Corrected highlighting of unmodified values in Config section of the About Trac page ([#6551). - New helper methods on `DatabaseManager` class for plugins to upgrade the database (#8172). - New `[notification-subscriber]` config section for general configuration of notification subscription defaults and `SubscriberList` macro (#11875). - Removed dependency on `ConfigObj` for TracFineGrainedPermissions (#11982). - `Image` macro supports InterWiki prefixes (#12025). Besides the few issues listed here, the fixes made for 0.12.7 and 1.0.6 are also included. You can find all the detailed release notes at: - http://trac.edgewall.org/wiki/TracDev/ReleaseNotes/1.1#DevelopmentReleases - http://trac.edgewall.org/wiki/TracDev/ReleaseNotes/1.0#MaintenanceReleases Download URLs: http://download.edgewall.org/trac/Trac-1.1.5.tar.gz http://download.edgewall.org/trac/Trac-1.1.5.win32.exe http://download.edgewall.org/trac/Trac-1.1.5.win-amd64.exe http://download.edgewall.org/trac/Trac-1.1.5.zip MD5 sums: 8f53ae0f9cd4b0a0b55f0e273dae3c37 Trac-1.1.5.zip c4547e2b6c7e1b174ccafa47227159e1 Trac-1.1.5.tar.gz 3dd67a28440487742264d0f87ace26e2 Trac-1.1.5.win32.exe be7c34e53f429e90dc0bfd7840f6b3e1 Trac-1.1.5.win-amd64.exe SHA1 sums: e00d8211cf558424efa98a36d90e9d39aad5e1b3 Trac-1.1.5.zip 29ffaa71a5256c6b514a5e5442de78718e5be1ed Trac-1.1.5.tar.gz 5f6f851f662c7fbd1bd6d83e7b5953452b400fe1 Trac-1.1.5.win32.exe 418f84f854c0059b7823152db2813620a03d7589 Trac-1.1.5.win-amd64.exe Enjoy! - The Trac Team http://trac.edgewall.org/

winpysetup easy setup of multiple python versions on a clean windows system
by Anthon van der Neut 18 May '15

18 May '15

I am happy to announce the availability of winpysetup version 0.2 dd 2015-05-18 Winpysetup ( https://bitbucket.org/ruamel/winpysetup/ ) allows setting up a clean testing on Windows for multiple python versions without downloading and installing MSI installers, prerequisites, all the time waiting for the last to finish in order to click a few options to start the next install. - install Windows (or clone your clean Windows Virtual Machine) - Download winpysetup.exe and start it. ( https://bitbucket.org/ruamel/winpysetup/downloads/winpysetup.exe ) - Once the program is done (now is a good time to make another snapshot if you run Windows in a VM), open a new Command Prompt (to get the change in PATH) and change to a directory without spaces in the path (e.g. C:\src). - Run: hg clone --insecure https://hg@bitbucket.org/ruamel/minimal - Change to the minimal directory and run tox. - Watch how tox invokes py.test succesfully against Python 2.7/2.6/3.3/3.4 and pypy (you can of course run tox immediately on your own, more interesting, code as well). Installed items include: pip, easy_install, mercurial, tox, detox, py.test and the Visual C compiler for Python 2.7 Special hooks can change the behavior of the installer. In particular: - the list of python versions to install can be easily extended/reduced - the list of default packages to install can be extended/reduced winpysetup has been testen on: WinXP with Service Pack 2 (32 bit) Windows 7 (32 and 64 bit) Feedback is welcome, in particular if tested on other Windows environments to which I currently don't have access. Thanks to Holger Krekel for confirming that automating a Windows box setup would be a good idea, and to the VirtualBox developers for making the execution of 250+ test installs less time consuming.

[ANN] bcolz v0.9.0
by Valentin Haenel 17 May '15

17 May '15

====================== Announcing bcolz 0.9.0 ====================== What's new ========== This is mostly a smallish feature and bugfix release. One large topic was implementing 'addcol' and 'delcol' to properly handle on-disk tables. 'addcol' now has a new keyword argument 'move' that allows you to specify if you want to move or copy the data. 'delcol' has a new keyword argument 'keep' which allows you preserve the data on disk when removing a column. Additionally, ctable now supports an 'auto_flush' keyword that makes it flush to disk automatically after any methods that may write data. Another important aspect is handling the GIL. In this release, we do keep the GIL while calling Blosc compress and decompress in order to support lock-free operation of newer Blosc versions (1.5.x and beyond) that no longer have a global state. Furthermore we now distribute the 'carray_ext.pxd' as part of the package via PyPi to ease building applications on bcolz, for example *bquery*. Finally, the Sphinx based API documentation is now autogenerated from the docstrings in the Python sources. For the full list, please check the release notes at: https://github.com/Blosc/bcolz/blob/v0.9.0/RELEASE_NOTES.rst What it is ========== *bcolz* provides columnar and compressed data containers that can live either on-disk or in-memory. Column storage allows for efficiently querying tables with a large number of columns. It also allows for cheap addition and removal of column. In addition, bcolz objects are compressed by default for reducing memory/disk I/O needs. The compression process is carried out internally by Blosc, an extremely fast meta-compressor that is optimized for binary data. Lastly, high-performance iterators (like ``iter()``, ``where()``) for querying the objects are provided. bcolz can use numexpr internally so as to accelerate many vector and query operations (although it can use pure NumPy for doing so too). numexpr optimizes the memory usage and use several cores for doing the computations, so it is blazing fast. Moreover, since the carray/ctable containers can be disk-based, and it is possible to use them for seamlessly performing out-of-memory computations. bcolz has minimal dependencies (NumPy), comes with an exhaustive test suite and fully supports both 32-bit and 64-bit platforms. Also, it is typically tested on both UNIX and Windows operating systems. Together, bcolz and the Blosc compressor, are finally fulfilling the promise of accelerating memory I/O, at least for some real scenarios: http://nbviewer.ipython.org/github/Blosc/movielens-bench/blob/master/queryi… Other users of bcolz are Visualfabriq (http://www.visualfabriq.com/) the Blaze project (http://blaze.pydata.org/), Quantopian (https://www.quantopian.com/) and Scikit-Allel (https://github.com/cggh/scikit-allel) which you can read more about by pointing your browser at the links below. * Visualfabriq: * *bquery*, A query and aggregation framework for Bcolz: * https://github.com/visualfabriq/bquery * Blaze: * Notebooks showing Blaze + Pandas + BColz interaction: * http://nbviewer.ipython.org/url/blaze.pydata.org/notebooks/timings-csv.ipynb * http://nbviewer.ipython.org/url/blaze.pydata.org/notebooks/timings-bcolz.ip… * Quantopian: * Using compressed data containers for faster backtesting at scale: * https://quantopian.github.io/talks/NeedForSpeed/slides.html * Scikit-Allel * Provides an alternative backend to work with compressed arrays * https://scikit-allel.readthedocs.org/en/latest/bcolz.html Installing ========== bcolz is in the PyPI repository, so installing it is easy:: $ pip install -U bcolz Resources ========= Visit the main bcolz site repository at: http://github.com/Blosc/bcolz Manual: http://bcolz.blosc.org Home of Blosc compressor: http://blosc.org User's mail list: bcolz(a)googlegroups.com http://groups.google.com/group/bcolz License is the new BSD: https://github.com/Blosc/bcolz/blob/master/LICENSES/BCOLZ.txt Release notes can be found in the Git repository: https://github.com/Blosc/bcolz/blob/master/RELEASE_NOTES.rst ---- **Enjoy data!**
