ANN: RPQueue 0.22
by Josiah Carlson Oct. 9, 2013

Oct. 9, 2013

Hello everyone, For those of you who didn't know, if you are interested in a Redis-backed time and/or fifo-queue with priorities, retries, etc., to be used with Python, one exists and is mature: it's called RPQueue, and it seeks to simplify your life of task execution. The recent changelog entries are below my signature. The package has been around for two years next month, and does exactly what you expect it to do - no more, no less. You can find the package at: https://github.com/josiahcarlson/rpqueue/ https://pypi.python.org/pypi/rpqueue Please CC me on any replies if you have any questions or comments. Thank you, - Josiah #----------------------------------- 0.22 ------------------------------------ [fixed] setup.py-based installations. Ran into the bug myself :/ #----------------------------------- 0.21 ------------------------------------ [changed] where available, rpqueue will now use Lua to move delayed tasks from the time-based priority queue to fifo queues. This should reduce overhead in all cases, and should drastically improve performance for those that use large numbers of delayed tasks. [changed] the version number is now PEP 386/440 compliant. [added] this changelog that will document updates/changes/improvements in an easily referenced location. [fixed] thanks to https://github.com/dmaust , rpqueue added a missing 'redis' requirement.

PROPOSAL: PyCons in Africa
by real-not-anti-spam-address＠apple-juice.co.uk Oct. 8, 2013

Oct. 8, 2013

I have a written a first draft outlining a proposal for a PyCon in a sub-Saharan African nation where there has never been one. <http://pycons-in-africa.readthedocs.org> There's an email list for people interested in becoming involved in the idea: <http://groups.google.com/group/pycons-in-africa>. I'm seeking support for the proposal, from all parties who'd need to be involved, from Python user groups in African cities where a PyCon might be viable, to people who'd want to take part and the wider Python community. If anyone would like to add themselves to the list of potential collaborators on this, please do so using GitHub: <https://github.com/evildmp/pycons-in-africa/blob/master/docs/collaborat ors.rst>. If you can't do that, just ask me to add the information. There's a wiki on GitHub too: <https://github.com/evildmp/pycons-in-africa/wiki>. I'm also seeking critical opinions on this, so if you think it's a poor idea, or poorly conceived, or that there would be better ways to achieve the aims in the proposal, or something key that's missing from it, I would like to hear why you think that, so I can address any problems. Thanks, Daniele

by David Malcolm Oct. 8, 2013

Oct. 8, 2013

"firehose" is a Python package intended for managing the results from code analysis tools (e.g. compiler warnings, static analysis, linters, etc). It currently provides parsers for the output of gcc, clang-analyzer, cppcheck, and findbugs. These parsers convert the results into a common data model of Python objects, with methods for lossless roundtrips through a provided XML format. There is also a JSON equivalent. It is available on pypi here: https://pypi.python.org/pypi/firehose and via git from: https://github.com/fedora-static-analysis/firehose The mailing list is: https://admin.fedoraproject.org/mailman/listinfo/firehose-devel Firehose is Free Software, licensed under the LGPLv2.1 or (at your option) any later version. It requires Python 2.7 or 3.2 onwards, and has been successfully tested with PyPy. Changes since 0.2: This release adds a parser for the output of the findbugs tool, along with various bugfixes and other internal cleanups. Thanks to Léo Cavaillé, Matthieu Caneill, Nicolas Dandrimont, and yeshuxiong for their help with this release. Enjoy! Dave

pytest-2.4: may better fixtures be with you
by holger krekel Oct. 4, 2013

Oct. 4, 2013

The just released pytest-2.4.0 brings many improvements and numerous bug fixes while remaining plugin- and test-suite compatible apart from a few supposedly very minor incompatibilities. See below for a full list of details. A few feature highlights: - new yield-style fixtures `pytest.yield_fixture <http://pytest.org/latest/yieldfixture.html>`_, allowing to use existing with-style context managers in fixture functions. - improved pdb support: ``import pdb ; pdb.set_trace()`` now works without requiring prior disabling of stdout/stderr capturing. Also the ``--pdb`` options works now on collection and internal errors and we introduced a new experimental hook for IDEs/plugins to intercept debugging: ``pytest_exception_interact(node, call, report)``. - shorter monkeypatch variant to allow specifying an import path as a target, for example: ``monkeypatch.setattr("requests.get", myfunc)`` - better unittest/nose compatibility: all teardown methods are now only called if the corresponding setup method succeeded. - integrate tab-completion on command line options if you have `argcomplete <http://pypi.python.org/pypi/argcomplete>`_ configured. - allow boolean expression directly with skipif/xfail if a "reason" is also specified. - a new hook ``pytest_load_initial_conftests`` allows plugins like `pytest-django <http://pypi.python.org/pypi/pytest-django>`_ to influence the environment before conftest files import ``django``. - reporting: color the last line red or green depending if failures/errors occured or everything passed. The documentation has been updated to accomodate the changes, see `http://pytest.org <http://pytest.org>`_ To install or upgrade pytest:: pip install -U pytest # or easy_install -U pytest **Many thanks to all who helped, including Floris Bruynooghe, Brianna Laugher, Andreas Pelme, Anthon van der Neut, Anatoly Bubenkoff, Vladimir Keleshev, Mathieu Agopian, Ronny Pfannschmidt, Christian Theunert and many others.** may passing tests be with you, holger krekel Changes between 2.3.5 and 2.4 ----------------------------------- known incompatibilities: - if calling --genscript from python2.7 or above, you only get a standalone script which works on python2.7 or above. Use Python2.6 to also get a python2.5 compatible version. - all xunit-style teardown methods (nose-style, pytest-style, unittest-style) will not be called if the corresponding setup method failed, see issue322 below. - the pytest_plugin_unregister hook wasn't ever properly called and there is no known implementation of the hook - so it got removed. - pytest.fixture-decorated functions cannot be generators (i.e. use yield) anymore. This change might be reversed in 2.4.1 if it causes unforeseen real-life issues. However, you can always write and return an inner function/generator and change the fixture consumer to iterate over the returned generator. This change was done in lieu of the new ``pytest.yield_fixture`` decorator, see below. new features: - experimentally introduce a new ``pytest.yield_fixture`` decorator which accepts exactly the same parameters as pytest.fixture but mandates a ``yield`` statement instead of a ``return statement`` from fixture functions. This allows direct integration with "with-style" context managers in fixture functions and generally avoids registering of finalization callbacks in favour of treating the "after-yield" as teardown code. Thanks Andreas Pelme, Vladimir Keleshev, Floris Bruynooghe, Ronny Pfannschmidt and many others for discussions. - allow boolean expression directly with skipif/xfail if a "reason" is also specified. Rework skipping documentation to recommend "condition as booleans" because it prevents surprises when importing markers between modules. Specifying conditions as strings will remain fully supported. - reporting: color the last line red or green depending if failures/errors occured or everything passed. thanks Christian Theunert. - make "import pdb ; pdb.set_trace()" work natively wrt capturing (no "-s" needed anymore), making ``pytest.set_trace()`` a mere shortcut. - fix issue181: --pdb now also works on collect errors (and on internal errors) . This was implemented by a slight internal refactoring and the introduction of a new hook ``pytest_exception_interact`` hook (see next item). - fix issue341: introduce new experimental hook for IDEs/terminals to intercept debugging: ``pytest_exception_interact(node, call, report)``. - new monkeypatch.setattr() variant to provide a shorter invocation for patching out classes/functions from modules: monkeypatch.setattr("requests.get", myfunc) will replace the "get" function of the "requests" module with ``myfunc``. - fix issue322: tearDownClass is not run if setUpClass failed. Thanks Mathieu Agopian for the initial fix. Also make all of pytest/nose finalizer mimick the same generic behaviour: if a setupX exists and fails, don't run teardownX. This internally introduces a new method "node.addfinalizer()" helper which can only be called during the setup phase of a node. - simplify pytest.mark.parametrize() signature: allow to pass a CSV-separated string to specify argnames. For example: ``pytest.mark.parametrize("input,expected", [(1,2), (2,3)])`` works as well as the previous: ``pytest.mark.parametrize(("input", "expected"), ...)``. - add support for setUpModule/tearDownModule detection, thanks Brian Okken. - integrate tab-completion on options through use of "argcomplete". Thanks Anthon van der Neut for the PR. - change option names to be hyphen-separated long options but keep the old spelling backward compatible. py.test -h will only show the hyphenated version, for example "--collect-only" but "--collectonly" will remain valid as well (for backward-compat reasons). Many thanks to Anthon van der Neut for the implementation and to Hynek Schlawack for pushing us. - fix issue 308 - allow to mark/xfail/skip individual parameter sets when parametrizing. Thanks Brianna Laugher. - call new experimental pytest_load_initial_conftests hook to allow 3rd party plugins to do something before a conftest is loaded. Bug fixes: - fix issue358 - capturing options are now parsed more properly by using a new parser.parse_known_args method. - pytest now uses argparse instead of optparse (thanks Anthon) which means that "argparse" is added as a dependency if installing into python2.6 environments or below. - fix issue333: fix a case of bad unittest/pytest hook interaction. - PR27: correctly handle nose.SkipTest during collection. Thanks Antonio Cuni, Ronny Pfannschmidt. - fix issue355: junitxml puts name="pytest" attribute to testsuite tag. - fix issue336: autouse fixture in plugins should work again. - fix issue279: improve object comparisons on assertion failure for standard datatypes and recognise collections.abc. Thanks to Brianna Laugher and Mathieu Agopian. - fix issue317: assertion rewriter support for the is_package method - fix issue335: document py.code.ExceptionInfo() object returned from pytest.raises(), thanks Mathieu Agopian. - remove implicit distribute_setup support from setup.py. - fix issue305: ignore any problems when writing pyc files. - SO-17664702: call fixture finalizers even if the fixture function partially failed (finalizers would not always be called before) - fix issue320 - fix class scope for fixtures when mixed with module-level functions. Thanks Anatloy Bubenkoff. - you can specify "-q" or "-qq" to get different levels of "quieter" reporting (thanks Katarzyna Jachim) - fix issue300 - Fix order of conftest loading when starting py.test in a subdirectory. - fix issue323 - sorting of many module-scoped arg parametrizations - make sessionfinish hooks execute with the same cwd-context as at session start (helps fix plugin behaviour which write output files with relative path such as pytest-cov) - fix issue316 - properly reference collection hooks in docs - fix issue 306 - cleanup of -k/-m options to only match markers/test names/keywords respectively. Thanks Wouter van Ackooy. - improved doctest counting for doctests in python modules -- files without any doctest items will not show up anymore and doctest examples are counted as separate test items. thanks Danilo Bellini. - fix issue245 by depending on the released py-1.4.14 which fixes py.io.dupfile to work with files with no mode. Thanks Jason R. Coombs. - fix junitxml generation when test output contains control characters, addressing issue267, thanks Jaap Broekhuizen - fix issue338: honor --tb style for setup/teardown errors as well. Thanks Maho. - fix issue307 - use yaml.safe_load in example, thanks Mark Eichin. - better parametrize error messages, thanks Brianna Laugher - pytest_terminal_summary(terminalreporter) hooks can now use ".section(title)" and ".line(msg)" methods to print extra information at the end of a test run.

ANN: rom 0.21 - Redis object mapper for Python
by Josiah Carlson Oct. 2, 2013

Oct. 2, 2013

Hey everyone, As time progresses, so does my Redis object mapper. The "rom" package is a Redis object mapper for Python. It sports an interface similar to Django's ORM, SQLAlchemy + Elixir, or Appengine's datastore. The changelog for recent releases can be seen below my signature. You can find the package at: https://www.github.com/josiahcarlson/rom https://pypi.python.org/pypi/rom And docs can be found at: http://pythonhosted.org/rom/ Please CC me on any replies if you have any questions or comments. Thank you, - Josiah #----------------------------------- 0.21 ------------------------------------ [fixed] upload for rom 0.20 was missing new columns.py, now fixed #----------------------------------- 0.20 ------------------------------------ [changed] Added exception when performing .all(), .execute(), or .count() on query objects that have had no filters or attribute ordering provided. This addresses issue #12. [changed] Moved column definitions to their own module, shouldn't affect any normal uses of rom. [added] For users of Redis 2.6 and later, there is a beta Lua-enabled writing option that allows for multiple unique columns on models. In some cases, this may improve performance when writing many entities very quickly. [added] The ability to reload an entity from Redis, optionally discarding any modifications to the object itself. Check out the documentation for Model.refresh(), Session.refresh(), and Session.refresh_all() [added] Tests for the newly changed/added features. [changed] Tests no longer use flushdb() - all test models/indexes/etc. are prefixed with RomTest, and we find/delete such keys before and after any tests are run. Now anyone can reasonably run the test suite. #----------------------------------- 0.19 ------------------------------------ [fixed] Thanks to a bug report by https://github.com/MickeyKim , was notified of a bug when using unique indexes, which is now fixed and has a testcase. #----------------------------------- 0.18 ------------------------------------ [fixed] Thanks to a bug report by https://github.com/MickeyKim , was notified and received an interim patch for a bug that could cause deleted entities to be resurrected on session.commit() or session.flush() . This has now been fixed and a testcase has been added.
