19 Nov '15

Hello Everyone, i'm pleased to announce the release of pytest-2.8.3: bug fixes ======================= 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 2.8.2. 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 Florian Bruhin Gabe Hollombe Gabriel Reis Hartmut Goebel John Vandenberg Lee Kamentsky Michael Birtwell Raphael Pierzina Ronny Pfannschmidt William Martin Stewart Happy testing, The py.test Development Team 2.8.3 (compared to 2.8.2) ----------------------------- - fix #1169: add __name__ attribute to testcases in TestCaseFunction to support the @unittest.skip decorator on functions and methods. Thanks Lee Kamentsky for the PR. - fix #1035: collecting tests if test module level obj has __getattr__(). Thanks Suor for the report and Bruno Oliveira / Tom Viner for the PR. - fix #331: don't collect tests if their failure cannot be reported correctly e.g. they are a callable instance of a class. - fix #1133: fixed internal error when filtering tracebacks where one entry belongs to a file which is no longer available. Thanks Bruno Oliveira for the PR. - enhancement made to highlight in red the name of the failing tests so they stand out in the output. Thanks Gabriel Reis for the PR. - add more talks to the documentation - extend documentation on the --ignore cli option - use pytest-runner for setuptools integration - minor fixes for interaction with OS X El Capitan system integrity protection (thanks Florian)

devpi-{server,web}-2.5.0 perf/bug fix releases
by holger krekel 19 Nov '15

19 Nov '15

We just released devpi-{server,web}-2.5.0 to pypi, see changelogs below for more details. While it's not required to do an export/import cycle for this release it's recommended especially if you are running with replicas. Docs for the private pypi packaging server at: http://doc.devpi.net Thanks to Florian Schulze, Jason R. Coombs and all issue reporters. For your information, we are now starting work for devpi-server-3.0 which will introduce further speedups, internal code simplifications and new features (like mirroring from arbitrary pypi-servers). cheers, holger krekel server-2.5.0 (2015-11-19) ------------------------- - fix a regression of 2.3.0 which would cause many write-transactions for mirrored simple-page entries that didn't change. Previous to the fix, accesses to mirrored simple pages will result in a new write-transaction every 30 minutes if the page is accessed which is likely on a somewhat busy site. If you running with replicas it is recommended to do an an export/import cycle to remove all the unneccessary writes that were produced since devpi-server-2.3.0. They delay the setup of new replicas considerably. - add info about pypi_whitelist on simple page when root/pypi is blocked for a project. - replica simple-page serving will not unneccessarily wait for new simple-page entries to arrive at the replication side if the master does not return any changes in the initial simple-page request. Previously a replica would wait for the replication-thread to catch up even if no links changed. - fix setup.py to work on py34 and with LANG="C" environments. Thanks Jason R. Coombs. - fix issue284: allow users who are listed in acl_upload to delete packages web-2.5.0 (2015-11-19) ---------------------- - fix issue288: classifiers rendering wrong with read only data views - index.pt, project.pt, version.pt: added info about pypi_whitelist. This requires devpi-server > 2.4.0 to work. - fix issue286: indexing of most data failed due to new read only views

ANN: bcolz 0.12.0 released
by Francesc Alted 16 Nov '15

16 Nov '15

======================= Announcing bcolz 0.12.0 ======================= What's new ========== This release copes with some compatibility issues with NumPy 1.10. Also, several improvements have happened in the installation procedure, allowing for a smoother process. Last but not least, the tutorials haven been migrated to the IPython notebook format (a huge thank you to Francesc Elies for this!). This will hopefully will allow users to better exercise the different features of bcolz. For a more detailed change log, see: https://github.com/Blosc/bcolz/blob/master/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/model/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!** -- Francesc Alted

devpi-server-2.4.0 and friends: speedup, fixes, profiling
by holger krekel 11 Nov '15

11 Nov '15

We just pushed devpi-{server,web,client,common} release files out to pypi. Most notably, the private pypi package server allows much faster installs due to much improved simple-page serving speed. See the changelog below for a host of other changes and fixes as well as for compatibility warnings. Docs about the devpi system are to be found here: http://doc.devpi.net Many thanks to my co-maintainer Florian Schulze and particularly to Stephan Erb and Chad Wagner for their contributions. cheers, holger -- about me: http://holgerkrekel.net/about-me/ contracting: http://merlinux.eu devpi-server 2.4.0 (2015-11-11) ------------------------------- - NOTE: devpi-server-2.4 is compatible to data from devpi-server-2.3 but not the other way round. Once you run devpi-server-2.4 you can not go back. It's always a good idea to make a backup before trying a new version :) - NOTE: if you use "--logger-cfg" with .yaml files you will need to install pyyaml yourself as devpi-server-2.4 dropped it as a direct dependency as it does not install for win32/python3.5 and is not needed for devpi-server operations except for logging configuration. Specifying a *.json file always works. - add timeout to replica requests - fix issue275: improve error message when a serverdir exists but has no version - improve testing mechanics and name normalization related to storing doczips - refine keyfs to provide lazy deep readonly-views for dict/set/list/tuple types by default. This introduces safety because users (including plugins) of keyfs-values can only write/modify a value by explicitly getting it with readonly=False (thereby deep copying it) and setting it with the transaction. It also allows to avoid unnecessary copy-operations when just reading values. - fix issue283: pypi cache didn't work for replicas. - performance improvements for simple pages with lots of releases. this also changed the db layout of the caching from pypi.python.org mirrors but will seamlessly work on older data, see NOTE at top. - add "--profile-requests=NUM" option which turns on per-request profiling and will print out after NUM requests are executed and then restart profiling. - fix tests for pypy. We officially support pypy now. devpi-client-2.3.2 (2015-11-11) ------------------------------- - fix git submodules for devpi upload. ``.git`` is a file not a folder for submodules. Before this fix the repository which contains the submodule was found instead, which caused a failure, because the files aren't tracked there. - new option "devpi upload --setupdir-only" which will only vcs-export the directory containing setup.py. You can also set "setupdirs-only = 1" in the "[devpi:upload]" section of setup.cfg for the same effect. Thanks Chad Wagner for the PR. devpi-web 2.4.2 (2015-11-11) ---------------------------- - log exceptions during search index updates. - adapted tests/code to work with devpi-server-2.4 devpi-common 2.0.8 (2015-11-11) ------------------------------- - fix URL.joinpath to not add double slashes

tox-2.2.0: fixes and new ignore_outcome setting
by holger krekel 11 Nov '15

11 Nov '15

I just released tox-2.2.0, see changelog below. More about tox here: http://tox.testrun.org have fun, holger -- about me: http://holgerkrekel.net/about-me/ contracting: http://merlinux.eu 2.2.0 ----- - fix issue265 and add LD_LIBRARY_PATH to passenv on linux by default because otherwise the python interpreter might not start up in certain configurations (redhat software collections). Thanks David Riddle. - fix issue246: fix regression in config parsing by reordering such that {envbindir} can be used again in tox.ini. Thanks Olli Walsh. - fix issue99: the {env:...} substitution now properly uses environment settings from the ``setenv`` section. Thanks Itxaka Serrano. - fix issue281: make --force-deps work when urls are present in dependency configs. Thanks Glyph Lefkowitz for reporting. - fix issue174: add new ``ignore_outcome`` testenv attribute which can be set to True in which case it will produce a warning instead of an error on a failed testenv command outcome. Thanks Rebecka Gulliksson for the PR. - fix issue280: properly skip missing interpreter if {envsitepackagesdir} is present in commands. Thanks BB:ceridwenv
