tox-1.7.0: many bug fixes and little improvements
by holger krekel Jan. 29, 2014

Jan. 29, 2014

Just released tox-1.7.0 (finally), the generic virtualenv-based test runner for Python. It contains a lot of fixes and improvements although there are some bugs remaining. While a lot of pull requests are thankfully offered i could use some more co-maintaining/reviewing to allow for some faster progress. Anyway, to install to 1.7.0 : pip install -U tox and to look at the docs: https://testrun.org/tox/latest/ have fun, holger 1.7.0 --------- - don't lookup "pip-script" anymore but rather just "pip" on windows as this is a pip implementation detail and changed with pip-1.5. It might mean that tox-1.7 is not able to install a different pip version into a virtualenv anymore. - drop Python2.5 compatibility because it became too hard due to the setuptools-2.0 dropping support. tox now has no support for creating python2.5 based environments anymore and all internal special-handling has been removed. - merged PR81: new option --force-dep which allows to override tox.ini specified dependencies in setuptools-style. For example "--force-dep 'django<1.6'" will make sure that any environment using "django" as a dependency will get the latest 1.5 release. Thanks Bruno Oliveria for the complete PR. - merged PR125: tox now sets "PYTHONHASHSEED" to a random value and offers a "--hashseed" option to repeat a test run with a specific seed. You can also use --hashsheed=notset to instruct tox to leave the value alone. Thanks Chris Jerdonek for all the work behind this. - fix issue132: removing zip_safe setting (so it defaults to false) to allow installation of tox via easy_install/eggs. Thanks Jenisys. - fix issue126: depend on virtualenv>=1.11.2 so that we can rely (hopefully) on a pip version which supports --pre. (tox by default uses to --pre). also merged in PR84 so that we now call "virtualenv" directly instead of looking up interpreters. Thanks Ionel Maries Cristian. This also fixes issue140. - fix issue130: you can now set install_command=easy_install {opts} {packages} and expect it to work for repeated tox runs (previously it only worked when always recreating). Thanks jenisys for precise reporting. - fix issue129: tox now uses Popen(..., universal_newlines=True) to force creation of unicode stdout/stderr streams. fixes a problem on specific platform configs when creating virtualenvs with Python3.3. Thanks Jorgen Schäfer or investigation and solution sketch. - fix issue128: enable full substitution in install_command, thanks for the PR to Ronald Evers - rework and simplify "commands" parsing and in particular posargs substitutions to avoid various win32/posix related quoting issues. - make sure that the --installpkg option trumps any usedevelop settings in tox.ini or - introduce --no-network to tox's own test suite to skip tests requiring networks - introduce --sitepackages to force sitepackages=True in all environments. - fix issue105 -- don't depend on an existing HOME directory from tox tests.

execnet-1.2 released: gevent/eventlet support, many improvements
by holger krekel Jan. 29, 2014

Jan. 29, 2014

Hi all, just released execnet-1.2, the tool for writing distributed zero-install python programs. The release contains lots of improvements and fixes. Most notably execnet now supports to use gevent/eventlet models on each of the initiating side and the remote side (configurable separately). See the changelog below for details. Install it via: pip install -U execnet Read the docs here: http://codespeak.net/execnet/ have fun playing, holger 1.2 -------------------------------- - fix issue22 -- during interpreter shutdown don't throw an exception when we can't send a termination sequence anymore as we are about to die anyway. - fix issue24 -- allow concurrent creation of gateways by guarding automatic id creation by a look. Thanks tlecomte. - majorly refactor internal thread and IO handling. execnet can now operate on different thread models, defaults to "thread" but allows for eventlet and gevent if it is installed. - gateway.remote_exec() will now execute in multiple threads on the other side by default. The previous neccessity of running "gateway.remote_init_threads()" to allow for such concurrency is gone. The latter method is now a no-op and will be removed in future versions of execnet. - fix issue20: prevent AttributError at interpreter shutdown by not trying to send close/last_message messages if the world around is half destroyed. - fix issue21: allow to create local gateways with sudo aka makegateway("popen//python=sudo python"). Thanks Alfredo Deza for the PR. - streamline gateway termination and simplify proxy implementation. add more internal tracing. - if execution hangs in computation, we now try to send a SIGINT to ourselves on Unix platforms instead of just calling thread.interrupt_main() - change license from GPL to MIT - introduce execnet.dump/load variants of dumps/loads serializing/unserializing mechanism. - improve channel.receive() communication latency on python2 by changing the default timeout of the underlying Queue.get to a regular None instead of the previous default -1 which caused an internal positive timeout value (a hack probably introduced to allow CTRL-C to pass through for <python2.5 versions). - extended ssh-syntax to allow passing of command line args, e.g. "ssh= -p 50 hostname". The options are passed to the underlying ssh client binary. Thanks tundish. - fix issue15: interoperability with inspect.getstack(). Thanks Peter Feiner. - fix issue10 : skip PYTHONDONTWRITEBYTECODE test if it we are running with PYTHONDONTWRITEBYTECODE set. - dont try the jython pid fixup on a RemoteIO - avoid accidentally setting exc_info() in gateway_base.py

pytest-xdist-1.10 released (distributed testing plugin)
by holger krekel Jan. 29, 2014

Jan. 29, 2014

Hi all, also released pytest-xdist-1.11 with some little improvements and speedups regarding overheads for distributing tests (maybe 10%, not too much). Install it with: pip install -U pytest-xdist and checkout the pypi page: https://pypi.python.org/pypi/pytest-xdist best, holger 1.10 ------------------------- - add glob support for rsyncignores, add command line option to pass additional rsyncignores. Thanks Anatoly Bubenkov. - fix pytest issue382 - produce "pytest_runtest_logstart" event again in master. Thanks Aron Curzon. - fix pytest issue419 by sending/receiving indices into the test collection instead of node ids (which are not neccessarily unique for functions parametrized with duplicate values) - send multiple "to test" indices in one network message to a slave and improve heuristics for sending chunks where the chunksize depends on the number of remaining tests rather than fixed numbers. This reduces the number of master -> node messages (but not the reverse direction)

Thanks Wolfgang L. for reporting and tracking it down. - fixed docs and code to use "pytest" instead of "py.test" almost everywhere. Thanks Jurko Gospodnetic for the complete PR. - fix issue425: mention at end of "py.test -h" that --markers and --fixtures work according to specified test path (or current dir) - fix issue413: exceptions with unicode attributes are now printed correctly also on python2 and with pytest-xdist runs. (the fix requires py-1.4.20) - copy, cleanup and integrate py.io capture from pylib 1.4.20.dev2 (rev 13d9af95547e) - address issue416: clarify docs as to conftest.py loading semantics - fix issue429: comparing byte strings with non-ascii chars in assert expressions now work better. Thanks Floris Bruynooghe. - make capfd/capsys.capture private, its unused and shouldnt be exposed

PyDev 3.3.3 Released
by Fabio Zadrozny Jan. 28, 2014

Jan. 28, 2014

Hi All, PyDev 3.3.3 has been released Details on PyDev: http://pydev.org Details on its development: http://pydev.blogspot.com LiClipse (PyDev standalone with goodies such as support for Django Templates, Kivy Language, Mako Templates, Html, Javascript, etc): http://brainwy.github.io/liclipse/ What is PyDev? --------------------------- PyDev is a plugin that enables users to use Eclipse for Python, Jython and IronPython development -- making Eclipse a first class Python IDE -- It comes with many goodies such as code completion, syntax highlighting, syntax analysis, code analysis, refactor, debug, etc. Release Highlights: ------------------------------- * **Important**: PyDev requires Eclipse 3.8 or 4.3 onwards and Java 7! For older versions, keep using PyDev 2.x (see LiClipse: http://brainwy.github.io/liclipse for a PyDev standalone with all requirements bundled). * **Code Completion**: - Compiled modules are now indexed and shown in the context-insensitive code-completion. - In an empty file, a code-completion request will show options related to creating modules (press Ctrl+Space twice to show only those templates). * **Performance**: - Building (indexing) of Python files is **much** faster. - Code completion does not get slown down by other analysis done in the background due to shell synchronization. * **Interactive Console**: - The interactive console now has tab-completion (so, tab can be used to show completions such as in IPython). * **Debugger**: - **Locals are now properly changed in the debugger** -- along with set next statement and auto-reloading this can make a debug session much more enjoyable! - Added a way to skip functions on a step-in on functions with **#@DontTrace** comments: - **Makes it possible to skip a lot of boilerplate code on a debug session!** - Can be enabled/disabled in the debugger preferences; - Ctrl+1 in a line with a method shows option to add **#@DontTrace** comment (if enabled in the preferences). - Debugging Stackless is much improved, especially for versions of Stackless released from 2014 onwards (special thanks to Anselm Kruis who improved stackless itself for this integration to work properly). - Reload during a debug session is improved and more stable: - Only updates what it can in-place or adds new attributes; - Shows what's being patched in the console output; - New hooks are provided for clients which may want to extend the reload; - See: Auto Reload in Debugger: http://pydev.org/manual_adv_debugger_auto_reload.html for more details. * **General**: - Compiled modules are now indexed, so, **fix import with Ctrl+1 now works with itertools, PyQt and other 'forced builtins'**. - When diffing a Python file, the PyDev comparison (with proper syntax highlighting) is now the default. - When finding a definition in a .pyd file, if there's a related .pyx in the same location, it's opened. - Running unit-tests will not try to import files that are in folders that don't have an __init__.py file. - Alt+Shift+O can be used to toggle mark occurrences. - Ctrl+3 not bound by default anymore on PyDev so that it does not conflict with the Eclipse Ctrl+3 (Ctrl+/ can be used instead). - Fixed recursion issue when finding file in pydev package explorer. - When configuring the interpreter, links are not followed when resolving entries for the PYTHONPATH. - It's possible to launch a directory containing a __main__.py file executable. - Fixed issues when creating django project without any existing project in the workspace. - Fixed deadlock on code-completion. - __pycache__ folders are hidden by default. * **Organize imports**: - When saving a file, if automatically organizing imports, don't remove unused imports even if that option is checked. - When saving a file, if automatically organizing imports, and nothing changes, don't change the buffer (so, no undo command is created). - @NoMove can be used in an import so that the import organizer doesn't mess with it. * **Refactoring**: - Fixed error when moving resource in PYTHONPATH to a dir out of the PYTHONPATH. - On a search make sure we search only python files, not dlls (which could give OutOfMemory errors and make the search considerably slower). - Multiple fixes on the rename module refactoring. Cheers, -- Fabio Zadrozny ------------------------------------------------------ Software Developer LiClipse http://brainwy.github.io/liclipse PyDev - Python Development Environment for Eclipse http://pydev.org http://pydev.blogspot.com
