Announce: Linux Desktop Testing Project (LDTP) 2.0.1 released
by Nagappan Alagappan Jan. 19, 2010

Jan. 19, 2010

Hello all, LDTPv2 a complete rewrite of LDTPv1 in Python. This release is dedicated to Eitan Isaacson[1]. Eitan wrote the LDTPv2 framework and important API's in LDTPv2 ! My co-workers in VMware Ranjith Murugan, Gaurav Sharma and Anupa Kamath, did a wonderful job in verifying the compatibility of LDTPv1 and v2. Special thanks to them and my manager Greg McShea on supporting this effort. Special thanks to Ara Pulido[2] for tracking the LDTPv2 status and pushing us to make the release at the earliest, as Ara wants to include LDTPv2 in Ubuntu Lucid, before feature freeze. Following are the difference between LDTPv1 and v2: * getlabel function is deprecated - you can use getobjectproperty('winodw', 'objectname', 'label') # To verify the display text * Label in v2 doesn't return the accelerator key (eg: in v1 "_Find" will be returned on v2 just "Find" is returned) * Strict data types are checked, in v1 most of the inputs are considered as string, if not they will be converted to string, but on v2 exception will be thrown, if incorrect type is passed to any function * In v1 we have ldtp binary, on v2 we need to check ldtpd.sh for now, this doesn't return the version for now, it has to be implemented, if you check for "ldtp --version" in v1 * In v1 each action command was given 1 second sleep time internally before execution, but on v2 there is no delay unless its set in environment variable LDTP_COMMAND_DELAY. So, the script has to use appropriate wait time * As Javier (from Ubuntu QA team) found, launchapp, argument name changed from 'arg' to 'args' Some of missing API in v2: * Calendar object * logFailures in v1 is not implemented in v2 * LDTP logging methods * appundertest * launchapp2 * blackoutregion * label object * panel object * ProcessStatistics LTFX is completely removed in LDTP v2 in favor of wnck implmentation Download LDTPv2 source from http://download.freedesktop.org/ldtp/2.x/2.0.x/ldtp2-2.0.1.tar.gz New dependency: python-twisted-web python-pyatspi python-gtk python-gnome Will schedule binary package building for different Linux distribution using openSUSE Build Service - http://download.opensuse.org/repositories/home:/anagappan:/ldtp2:/ Documentation references: For detailed information on LDTP framework and latest updates visit http://ldtp.freedesktop.org For information on various APIs in LDTP including those added for this release can be got from http://ldtp.freedesktop.org/user-doc/index.html Report bugs - http://ldtp.freedesktop.org/wiki/Bugs To subscribe to LDTP mailing lists, visit http://ldtp.freedesktop.org/wiki/Mailing_20list IRC Channel - #ldtp on irc.freenode.net Thanks Nagappan [1] - http://monotonous.org/ [2] - http://ubuntutesting.wordpress.com/ -- Linux Desktop (GUI Application) Testing Project - http://ldtp.freedesktop.org http://nagappanal.blogspot.com

py.test-1.2.0: junitxml, standalone test scripts, pluginization
by holger krekel Jan. 18, 2010

Jan. 18, 2010

Hi all, i just released some bits related to automated testing with Python: py-1.2.0: py.test core which grew junitxml, standalone-script generation pytest-xdist-1.0: separately installable dist-testing & looponfailing plugin pytest-figleaf-1.0: separately installable figleaf-coverage testing plugin See below or at this URL for the announcement: http://pylib.org/announce/release-1.2.0.html If you didn't experience much speed-up or previously had problems with distributed testing i recommend you try to install "pytest-xdist" now and see if it works better. For me it speeds up some tests runs by 500% on a 4 CPU machine due to its better internal model and several fixes. (It's five times because several tests depend on IO and don't block CPU meanwhile). Another tip: if you use "pip" (best with a virtualenv) you can do e.g.: pip install pytest-xdist pip uninstall pytest-xdist to conveniently activate/deactivate plugins for py.test. easy_install works ok as well but has no uninstall, yet remains the only option for installing with Python3 at the moment, though. You need to use the fine 'distribute' project's easy_install for the latter. cheers & have fun, holger py.test/pylib 1.2.0: junitxml, standalone test scripts, pluginization -------------------------------------------------------------------------------- py.test is an advanced automated testing tool working with Python2, Python3 and Jython versions on all major operating systems. It has a simple plugin architecture and can run many existing common Python test suites without modification. It offers some unique features not found in other testing tools. See http://pytest.org for more info. py.test 1.2.0 brings many bug fixes and interesting new abilities: * --junitxml=path will create an XML file for use with CI processing * --genscript=path creates a standalone py.test-equivalent test-script * --ignore=path prevents collection of anything below that path * --confcutdir=path only lookup conftest.py test configs below that path * a 'pytest_report_header' hook to add info to the terminal report header * a 'pytestconfig' function argument gives direct access to option values * 'pytest_generate_tests' can now be put into a class as well * on CPython py.test additionally installs as "py.test-VERSION", on Jython as py.test-jython and on PyPy as py.test-pypy-XYZ Apart from many bug fixes 1.2.0 also has better pluginization: Distributed testing and looponfailing testing now live in the separately installable 'pytest-xdist' plugin. The same is true for 'pytest-figleaf' for doing coverage reporting. Those two plugins can serve well now as blue prints for doing your own. thanks to all who helped and gave feedback, have fun, holger krekel, January 2010 Changes between 1.2.0 and 1.1.1 ===================================== - moved dist/looponfailing from py.test core into a new separately released pytest-xdist plugin. - new junitxml plugin: --junitxml=path will generate a junit style xml file which is processable e.g. by the Hudson CI system. - new option: --genscript=path will generate a standalone py.test script which will not need any libraries installed. thanks to Ralf Schmitt. - new option: --ignore will prevent specified path from collection. Can be specified multiple times. - new option: --confcutdir=dir will make py.test only consider conftest files that are relative to the specified dir. - new funcarg: "pytestconfig" is the pytest config object for access to command line args and can now be easily used in a test. - install 'py.test' and `py.which` with a ``-$VERSION`` suffix to disambiguate between Python3, python2.X, Jython and PyPy installed versions. - new "pytestconfig" funcarg allows access to test config object - new "pytest_report_header" hook can return additional lines to be displayed at the header of a test run. - (experimental) allow "py.test path::name1::name2::..." for pointing to a test within a test collection directly. This might eventually evolve as a full substitute to "-k" specifications. - streamlined plugin loading: order is now as documented in customize.html: setuptools, ENV, commandline, conftest. also setuptools entry point names are turned to canonical namees ("pytest_*") - automatically skip tests that need 'capfd' but have no os.dup - allow pytest_generate_tests to be defined in classes as well - deprecate usage of 'disabled' attribute in favour of pytestmark - deprecate definition of Directory, Module, Class and Function nodes in conftest.py files. Use pytest collect hooks instead. - collection/item node specific runtest/collect hooks are only called exactly on matching conftest.py files, i.e. ones which are exactly below the filesystem path of an item - change: the first pytest_collect_directory hook to return something will now prevent further hooks to be called. - change: figleaf plugin now requires --figleaf to run. Also change its long command line options to be a bit shorter (see py.test -h). - change: pytest doctest plugin is now enabled by default and has a new option --doctest-glob to set a pattern for file matches. - change: remove internal py._* helper vars, only keep py._pydir - robustify capturing to survive if custom pytest_runtest_setup code failed and prevented the capturing setup code from running. - make py.test.* helpers provided by default plugins visible early - works transparently both for pydoc and for interactive sessions which will regularly see e.g. py.test.mark and py.test.importorskip. - simplify internal plugin manager machinery - simplify internal collection tree by introducing a RootCollector node - fix assert reinterpreation that sees a call containing "keyword=..." - fix issue66: invoke pytest_sessionstart and pytest_sessionfinish hooks on slaves during dist-testing, report module/session teardown hooks correctly. - fix issue65: properly handle dist-testing if no execnet/py lib installed remotely. - skip some install-tests if no execnet is available - fix docs, fix internal bin/ script generation -- ----- End forwarded message ----- --

execnet-1.0.3: safer ssh-interpreter termination
by holger krekel Jan. 18, 2010

Jan. 18, 2010

execnet is a small and stable pure-python library for working with local or remote clusters of Python interpreters, with ease. It supports seamless instantiation of remote interpreters through the 'ssh' command line binary. The 1.0.3 release is a minor backward compatible release with these changes: - refine termination: CTRL-C and gateway.exit will now try harder to interrupt remote execution. this helps to avoid left-over ssh-processes. - fix read-on-non-blocking-files issue probably related to jython only: the low-level read on subprocess pipes may be non-blocking, returning less bytes than requested - so we now loop. - Windows/python2.4: fix bug that killing subprocesses would fail - make RemoteError and TimeoutError available directly on execnet namespace - fix some doc and test issues (thanks thm and ronny), add ssh_fileserver example - update internal copy of apipkg - always skip remote tests if no ssh specs given More info here: http://codespeak.net/execnet cheers, holger --

comtypes 0.6.2 released
by Thomas Heller Jan. 18, 2010

Jan. 18, 2010

I'm happy to announce the 0.6.2 comtypes release: http://sourceforge.net/projects/comtypes/ Here are the release notes: comtypes 0.6.2 released. Summary of important changes: - Several bug fixes for COM event handlers implemented in Python. - Allow typelib wrappers that (wrongly?) contain 'SAFEARRAY(VARIANT)*'. - DllCanUnloadNow() always returns S_FALSE in comtypes inproc COM servers. - The COM interfaces IViewObject, IViewObject2, and IViewObjectEx in the new module comtypes.viewobject. -------------------------------------------------------------------------- Detailed changelog since version 0.6.0: 2010-01-15 Thomas Heller <theller(a)python.net> * Bumped version number to 0.6.2. * CoUninitialize() returns nothing, not HRESULT. 2009-12-22 Thomas Heller <theller(a)python.net> * Bug fixes for event handlers implemented in Python. 2009-12-11 Thomas Heller <theller(a)python.net> * COM servers implemented in Python can now fire events; it did not work in some cases. * When an exception occurs in a COM event handler, a traceback is printed. 2009-11-26 Thomas Heller <theller(a)python.net> * Allow typelib wrappers that contain 'SAFEARRAY(VARIANT*)' parameter types to be imported. Calling these methods will fail, though. 2009-11-13 Thomas Heller <theller(a)python.net> * To avoid a memory leak when PyInitialize()/PyUninitialize() are called several times, return S_FALSE from inproc server's DllCanUnloadNow(). 2009-11-05 Thomas Heller <theller(a)python.net> * COMObject subclasses can now implement a _final_release_() method to free up resources, for example. This method is called when the COM reference count reaches zero. * Implement __hash__ method in dynamic dispatch classes. This fixes a 'python -3' warning. * comtypes\safearray.py: When numpy is not installed, creating safearrays took a very long time. This is fixed now. * comtypes\test\test_server.py: New way to test COM client and server. Work in progress. 2009-10-22 Thomas Heller <theller(a)python.net> * Support broken COM objects that provide IProvideClassInfo2, but not IProvideClassInfo (although the latter is derived from the former). See http://sourceforge.net/tracker/index.php?func=detail&aid=2829887&group_id=1… * Fixed a regression from the 0.4 version, [out] parameters didn't accept pointers or arrays any longer. Thanks again to Michael Eddington. 2009-10-19 Thomas Heller <theller(a)python.net> * Fix a memory leak in Python COM servers. Thanks to Michael Eddington for the patch. 2009-10-02 Thomas Heller <theller(a)python.net> * comtypes\test\test_server.py: Start a better approach to test both COM object calls and COM object implementations. 2009-09-09 Thomas Heller <theller(a)python.net> * Fix returning SAFEARRAY of VT_RECORDs. Based on a patch from Eduardo Arias. * New module comtypes.viewobject, contains the interfaces IViewObject, IViewObject2, IViewObjectEx. IAdviseSink is faked. * Change version number to 0.6.2dev. 2009-09-04 Thomas Heller <theller(a)python.net> * CoTaskMemFree does not return a HRESULT. Patch from James Teh. 2009-08-19 Thomas Heller <theller(a)python.net> * Bumped version number to 0.6.1. 2009-08-07 Thomas Heller <theller(a)python.net> * When an interface was specified in the call to IClassObject.CreateInstance, return that instead of calling GetBestInterface. Patch from James Teh. 2009-08-04 Thomas Heller <theller(a)python.net> * Added comtypes.CoGetClassObject() low-level function, comtypes.client.GetClassObject() high-level function, and implemented a pythonic interface to IClassFactory's CreateInstance method: def CreateInstance(self, punkouter=None, interface=None, dynamic=False) * Added the 'dynamic=False' parameter to the comtypes.client.CoGetObject and comtypes.client.GetActiveObject functions. Suggested by James Teh. 2009-06-17 Thomas Heller <theller(a)python.net> * comtypes.automation: Support VT_I8 and VT_UI8 SAFEARRAYs. * comtypes._comobject: Restore compatibility with Python 2.3. * Add the comtypes.IServiceProvider interface. Based on a patch from Michael Curran. 2009-04-30 Thomas Heller <theller(a)python.net> * Change version number in repository to 0.6.0.2dev. * Replace the VARIANTEnumerator implementation class in comtypes.server.automation with a new one which should actually be usable. * A completely new way how localserver and inproc server instances are managed: A comtypes.LocalServer or comtypes.InprocServer instance is attached to the comtypes.COMObject class at runtime. These changes keep localserver running as long as COMObject instances are alive. 2009-04-29 Thomas Heller <theller(a)python.net> * comtypes.errorinfo.ReportException now takes an additional 'stacklevel' named argument. * Add E_OUTOFMEMORY hresult code. * Register the InprocServer32 only when running as script or py2exe dll, not when running as py2exe exe server. 2009-04-25 Thomas Heller <theller(a)python.net> * SAFEARRAYs can now also be created from multi-dimensional numpy arrays. 2009-04-23 Thomas Heller <theller(a)python.net> * Change version number in repository to 0.6.0.1dev. * SAFEARRAYs can now also be created from array.array objects, and from (one-dimensional) numpy arrays. This is a lot faster than creating them from Python lists or tuples, at least for large arrays. * ctypes instances like c_int, c_ubyte, and so on can now be assigned to VARIANT().value. This allows to force creation of VARIANTs with the corresponding typecodes V_I4, VT_UI1 and alike. * Accept typelibs that contain SAFEARRAY(char). 2009-03-17 Thomas Heller <theller(a)python.net> * Fixed the return type of ITypeLib::ReleaseTLibAttr, which is documented wrongly in MSDN. The return type is void, not HRESULT. Reported to cause crashes on Windows 7. 2009-01-29 Thomas Heller <theller(a)python.net> * Restore compatibility with Python 2.3. * comtypes\client\_code_cache.py: Add missing 'import types' in comtypes\client\_code_cache.py. -- Thanks, Thomas -- Thanks, Thomas

Tornado this month, PyCon Dress Rehearsal next month at PyGTA
by Mike C. Fletcher Jan. 13, 2010

Jan. 13, 2010

We've got two fun months of PyGTA lined up. This month we'll be exploring the world of the Tornado web server (http://www.tornadoweb.org), next month we've got a 3-speaker dress rehearsal for PyCon 2010. The details: Tuesday, 19th January, 2010, 7pm Tornado Hacking Tornado <http://www.tornadoweb.org> (http://www.tornadoweb.org) is an Open Source non-blocking web server. It's used by FriendFeed to provide lightweight "server push" to the browser on the scale of thousands of simultaneous clients per server. We'll explore how to code with Tornado, and in particular, how to write callback-based asynchronous code. We'll also look at how server-push (polling, long-polling and streaming variants) works works on both the server and client side. If people are interested, we can also look at the REST-based CouchDB (asynchronous) client, or do some collaborative hacking on the ChatTrack (conference feedback tool) or TorChannels (generic push channels for Tornado) codebases. Tuesday, 16th February, 2010, 7pm (gather) PyCon Dress Rehearsal 3 PyCon 2010 Presenters will do a dress rehearsal of their PyCon 2010 presentations <http://us.pycon.org/2010/conference/talks/> just before they head down to Atlanta. All three talks are targeting beginner or general audiences, so feel free to bring along your new Pythonista friends. We have 3 PyCon previews scheduled: * Think Globally, Hack Locally - Teaching Python in Your Community — Leigh Honeywell * What We've Learned From Building Basie — Greg Wilson * Debating 'til Dawn: Topics to keep you up all night — Mike Fletcher We will give each presenter 20 minutes and then as much question/answer and feedback time as they want. At PyCon they'll only get 30 minutes total, but we want to give them as much feedback as possible so they can polish their presentation for the larger audience. We'll start the presentations at 7:30 (sharp) at Linux Caffe. If you bring a laptop, there will be an immediate feedback channel available. Directions to the venue, RSS feeds of upcoming events, and all the details are available on the web site: http://www.pygta.org Enjoy yourselves, Mike -- ________________________________________________ Mike C.

QOTW: "... if I want to know something new (be it a computer language or anything else, such as economics, history, science) I skip the introductory material and go directly to the discussion, to the issues.

Release of version 0.21.0 of CodeInvestigator
by hans moleman Jan. 11, 2010

Jan. 11, 2010

CodeInvestigator 0.21.0 was released on January 11. Bug changes: - In Windows, a shortcut was only created when an Administrator did the install: Administrator privileges are no longer required. Functionality changes: - Tabs styling. - Drive letters show in the sub-menu under Windows. - 'About' in Menu - Changed the code background colors. - Firefox doesn't need to be closed down before a restart of CI. You need Python 2.6 and Firefox for CodeInvestigator. CodeInvestigator is a tracing tool for Python programs. Running a program through CodeInvestigator creates a recording. Program flow, function calls, variable values and conditions are all stored for every line the program executes. The recording is then viewed with an interface consisting of the code. The code can be clicked: A clicked variable displays its value, a clicked loop displays its iterations. You read code, and have at your disposal all the run time details of that code. A computerized desk check tool and another way to learn about your program. http://sourceforge.net/project/showfiles.php?group_id=183942
