by holger krekel 24 Sep '14

24 Sep '14

tox 1.8: Generative/combinatorial environments specs ============================================================================= I am happy to announce tox 1.8 which implements parametrized environments and should otherwise be fully backward compatible to tox-1.7.2. See https://tox.testrun.org/latest/config.html#generating-environments-conditio… for examples and the new backward compatible syntax in your tox.ini file. Many thanks to Alexander Schepanovski for implementing and refining it based on the specifcation draft. More documentation about tox in general: http://tox.testrun.org/ Installation: pip install -U tox code hosting and issue tracking on bitbucket: https://bitbucket.org/hpk42/tox What is tox? ---------------- tox standardizes and automates tedious test activities driven from a simple ``tox.ini`` file, including: * creation and management of different virtualenv environments with different Python interpreters * packaging and installing your package into each of them * running your test tool of choice, be it nose, py.test or unittest2 or other tools such as "sphinx" doc checks * testing dev packages against each other without needing to upload to PyPI best, Holger Krekel, merlinux GmbH Changes 1.8 (compared to 1.7.2) --------------------------------------- - new multi-dimensional configuration support. Many thanks to Alexander Schepanovski for the complete PR with docs. And to Mike Bayer and others for testing and feedback. - fix issue148: remove "__PYVENV_LAUNCHER__" from os.environ when starting subprocesses. Thanks Steven Myint. - fix issue152: set VIRTUAL_ENV when running test commands, thanks Florian Ludwig. - better report if we can't get version_info from an interpreter executable. Thanks Floris Bruynooghe.

by holger krekel 24 Sep '14

24 Sep '14

pytest-2.6.3: fixes and little improvements =========================================================================== 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 drop-in compatible to 2.5.2 and 2.6.X. 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, among them: Floris Bruynooghe Oleg Sinyavskiy Uwe Schmitt Charles Cloud Wolfgang Schnerring have fun, holger krekel Changes 2.6.3 ====================== - fix issue575: xunit-xml was reporting collection errors as failures instead of errors, thanks Oleg Sinyavskiy. - fix issue582: fix setuptools example, thanks Laszlo Papp and Ronny Pfannschmidt. - Fix infinite recursion bug when pickling capture.EncodedFile, thanks Uwe Schmitt. - fix issue589: fix bad interaction with numpy and others when showing exceptions. Check for precise "maximum recursion depth exceed" exception instead of presuming any RuntimeError is that one (implemented in py dep). Thanks Charles Cloud for analysing the issue. - fix conftest related fixture visibility issue: when running with a CWD outside a test package pytest would get fixture discovery wrong. Thanks to Wolfgang Schnerring for figuring out a reproducable example. - Introduce pytest_enter_pdb hook (needed e.g. by pytest_timeout to cancel the timeout when interactively entering pdb). Thanks Wolfgang Schnerring. - check xfail/skip also with non-python function test items. Thanks Floris Bruynooghe.

PyGObject 3.14.0 Released
by Simon Feltman 23 Sep '14

23 Sep '14

I am pleased to announce version 3.14.0 of the Python bindings for GObject Introspection. This is the first stable release in the 3.14 series. This major release includes refactoring, bug-fixes, performance improvements, and a few API additions. Thanks to all the contributors and a special shout-out to Garrett Regier for some excellent refactoring and marshaling unification work for Python implemented virtual methods. This work enables out and inout array arguments for Python implemented virtual methods. Download ======== The new release is available from ftp.gnome.org: https://download.gnome.org/sources/pygobject/3.14/pygobject-3.14.0.tar.xz (703K) sha256sum: 779effa93f4b59cdb72f4ab0128fb3fd82900bf686193b570fd3a8ce63392d54 Notable changes since PyGObject 3.12.0 ====================================== - Gdk.Event supports setting union member fields directly based on the event type (Christoph Reiter) (#727810) - GLib.GError and GLib.Error are now unified (Simon Feltman) (#712519) - Non-introspected signals support marshaling cairo objects (Simon Feltman) (#694604) - GTypeClass methods show up as Python GObject class methods (Johan Dahlin) (#685218) - Widget.style_get_property and Container.child_get_property return values as Python native types when applicable, making the GValue argument optional. (Simon Feltman) (#685076) - Windows build fixes (Alexey Pavlov) (#734284, #734289, #734286, #734287) - Support for arrays with length fields on structs (Simon Feltman) (#688792) - Fast path Python property access (Simon Feltman) (#723872) - Memory leak fixes when accessing properties which are boxed types (Simon Feltman) (#726999) - [New API] Add gi.require_foreign (Simon Feltman) (#707735) - [New API] Add Gtk.Container.child_get/set overrides to match the C API (Simon Feltman) (#685076) - [New API] Add Python implementation of Object.connect_data() (Simon Feltman) (#701843) Contributors ============ Alexey Pavlov, Andre Klapper, Andrew Grigorev, Christoph Reiter, Garrett Regier, Ignacio Casal Quinteiro, Johan Dahlin, Martin Pitt, Olav Vitters, Paolo Borelli, Piotr Iwaniuk, Simon Feltman, Tobias Mueller About PyGObject =============== GObject is an object system used by GTK+, GStreamer and other libraries. 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.

ANN: Lea 1.3.1 released
by Pierre Denis 21 Sep '14

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...
