[issue17883] Fix buildbot testing of Tkinter
Zachary Ware added the comment: The buildbots appear to be happy, no more hanging and no more testLoadWithUNC failure. There is a failure in test_tcl on one bot, but it is not related to this issue. -- resolution: - fixed stage: patch review - committed/rejected status: open - closed ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue17883 ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue17883] Fix buildbot testing of Tkinter
Zachary Ware added the comment: Ok, I've managed to cobble together a buildbot setup to test the hang myself and have come up with a couple possible solutions. The first is to change the buildbot service on the slaves to allow desktop interaction. This way, the tests can actually run. If that's not possible, it's probably simplest to just pass -u-gui to the buildslaves in question, since there is in fact no gui available. That should at least fix the test_ttk_guionly problem. As for the test_tcl problem, how about this patch? It simply wraps the Popen call in a try/except, and converts to a skip in case of an 'Access is denied' error. -- nosy: +pitrou resolution: fixed - Added file: http://bugs.python.org/file30700/issue17883-skip-on-error.diff ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue17883 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

As it turns out, 3.3(+)'s test.support has an _is_gui_available function that prevents the hang, added in issue9931. Ironically, it was not added to 2.7 because the 2.7 buildbots weren't showing symptoms...because the tests weren't actually being run. I'll work on trying to backport the patch that added _is_gui_available, but my experience with ctypes is practically nil, so if anyone can get to it before I can post a patch, don't hold off on my account. -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue17883 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue17883] Fix buildbot testing of Tkinter
Terry J. Reedy added the comment:
Amaury and Martin: there is a problem on one machine with
test.test_tcl.TclTest.testLoadWithUNC that you two jointly wrote, reviewed, and
applied in #6470.
This issue (17883) is above getting the tcl/tk/tkinter tests to actually be run
on 2.7, which they were not before. Zack's patch succeeded in doing that, and
the tests all pass on all buildbots except (if I understand correctly) on one
Snakebite machine x86 Windows Server 2003 [SB] 2.7.
(According to http://buildbot.python.org/all/builders/, the only other
Server-2.7 bot is x86 Windows Server 2008 [SB] 2.7, and that seems not to have
run these tests: the most recent(?) log says test_tk skipped -- DLL load
failed: The specified module could not be found.. But if I understand, this
was back in January.)
With the original
f = os.popen('%s -c import Tkinter; print Tkinter' % (unc_name,))
f.read() returns '', so 'Tkinter' is not found in the null string and the
assertion that it is fails.
To get more info -- from an error traceback presumed to be on stderr -- we
tried using subprocess.POpen instead and the child process startup fails with
WindowsError: [Error 5] Access is denied, so the Python import is never
tried. Unless there is an error in the subprocess call or if Win Servers
require a different version of UNC, it would seem that the test is not at
fault.
a) Is Windows Server 2003 is really meant to be spported?
b) Are UNCs expected to behave differently on Server 2003?
c) Can UNCs be disabled on a particular machine?
In other words, should we just ignore this error, and possibly catch it with
'except WinError?

...which doesn't say much. Here's a patch that updates the test to use

The test passes on my machine with and without the patch, so I can't do much
more debugging until we get some useful output from the buildbot.

Terry J. Reedy added the comment:
I wonder if there is something special about the environment on that Snakebite
machine. At the top, it says
PATH=C:\Perl\site\bin;C:\Perl\bin;E:\apps\activestate-python-2.7.2.5-x86\;E:\apps\activestate-python-2.7.2.5-x86\Scripts;...
Could the presence of activestate-python affect the build?
Ignoring the 'no buffer in 3.0' warnings, there are a couple of warnings that
suggest updates to test_tcl.py. Another issue though.
The context for the failure is
with test_support.EnvironmentVarGuard() as env:
env.unset(TCL_LIBRARY)
f = os.popen('%s -c import Tkinter; print Tkinter' % (unc_name,))
self.assertTrue('Tkinter.py' in f.read())
I do not know why test_tcl is testing the ability of python to be opened from a
unc path (I am not familiar with them), but anyway...
The assertion is testing the read of the printed Tkinter module representation.
On my 2.7.4 install, the result is module 'Tkinter' from
'C:\Programs\Python27\lib\lib-tk\Tkinter.pyc'. On my machine, the test reads
that and passes. (On 3.x, the test is ('tkinter' in f.read()) as the file is
tkinter/__init__.py instead of Tkinter.py.)
To see what is going on with the failing machine, an update to
self.assertIn('Tkinter.py', f.read())
will show the f.read() that does not contain 'Tkinter.py'.

[issue17883] Fix buildbot testing of Tkinter
New submission from Zachary Ware: Ezio, you brought up the fact that the 2.7 Windows buildbots were skipping the Tkinter tests in Terry's core-mentorship thread about tkinter on Windows last month, and I've finally learned what is causing that failure. It appears that when 689a813f4afc and df39b0bc4106 were committed, they were not backported to 2.7. Attached is a patch to backport those two changesets, which should make things (more) right. This only affects running tests via PCbuild/rt.bat (or Tools/buildbot/test.bat, which calls PCbuild/rt.bat), and doesn't do anything for finding the tcl/tk .dlls any other time. -- components: Tests, Tkinter, Windows files: 2.7_rt.bat_tcltk_fix.diff keywords: patch messages: 188184 nosy: ezio.melotti, terry.reedy, zach.ware priority: normal severity: normal status: open title: Fix buildbot testing of Tkinter type: behavior versions: Python 2.7 Added file: http://bugs.python.org/file30080/2.7_rt.bat_tcltk_fix.diff ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue17883 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
