By default python doesn't run full test suite, but regrtest accepts -u parameter. The simplest way to reproduce is:

$ ./python -m test.regrtest -u gui test_ttk_guionly

[bitdancer]

It does not hang for me on Gentoo. When I run the test suite before a checkin, I use -uall, and I've never had test_ttk hang for me. I did an 'hg pull; hg up' before running the command line you give below.

[serhiy-storchaka]

$ ./python -m test.regrtest -u gui test_ttk_guionly

For me (on 32-bit Ubuntu 10.04, Tk 8.5) it failed:

test test_ttk_guionly failed -- Traceback (most recent call last):
  File "/home/serhiy/py/cpython/Lib/tkinter/test/test_ttk/test_widgets.py", line 579, in test_tab_identifiers
    self.fail("Tab with text 'a' not found")
AssertionError: Tab with text 'a' not found

[asvetlov]

For me it still fails. I use Ubuntu 12.04, 11.10 was failed also IIRC.

[asvetlov]

Update: test_ttk_guionly hangs on Ubuntu with Unity. It passed on Arch as well as on Ubuntu via xvfb-run.

[asvetlov]

Fir Unity it hangs on Tcl_ConditionWait inside Tcl_DoOneEvent function.

[serhiy-storchaka]

For me it passed with Openbox and Compiz, but fails with KWin.

Andrew, is this still a problem with current Unity? Or with updated version of tk 8.5, or any version of 8.6?

Should we downgrade this from 'critical'? After 3 years, it seems not to be ;-).

[ambv]

Unsetting priority.

[terryjreedy]

A year or so ago, I asked people on python-list who could to run the gui tests on their linux boxes and report. About 6 did and with one possible exception, and not that reported here, everyone reported success. So, unless someone can report otherwise, I think this should be closed.

I think we should regularly ask the community to help with gui tests.

[asvetlov]

Yes, everything works on Ubuntu 17.10
