[Python-Dev] regrtest hangs on test_tk_guionly

[Eric Smith]

In the trunk, test_tk_guionly hangs if I run it through regrtest. This 
is on a Fedora Core 6 box, without X installed.

If I run test_tk_guionly directly, it exits saying there's no DISPLAY 
set, which is what I'd expect:

------8<------------------
[trunk]$ ./python Lib/test/test_ttk_guionly.py
Traceback (most recent call last):
   File "Lib/test/test_ttk_guionly.py", line 11, in <module>
     raise test_support.TestSkipped("ttk not available: %s" % msg)
test.test_support.TestSkipped: ttk not available: no display name and no 
$DISPLAY environment variable
[29788 refs]
------8<------------------


If I run regrtest with (or without) -v, it hangs without any output from 
test_tk_guionly:

------8<------------------
...
OK
test_transformer
Test multiple targets on the left hand side. ... ok

----------------------------------------------------------------------
Ran 1 test in 0.020s

OK
test_ttk_guionly
<hangs here>
------8<------------------


I'm not seeing a problem in the py3k branch. There, test_tk_guionly is 
skipped:

------8<------------------
test_ttk_guionly
test_ttk_guionly skipped -- ttk not available: no display name and no 
$DISPLAY environment variable
------8<------------------

I'm not sure how to further isolate this, since I can't duplicate it 
when running the test by itself. I'm mostly curious if anyone else is 
seeing this problem. If it's just me, I'll just switch to a Mac, where 
the problem doesn't occur (if for no other reason, because ttk is not 
available). If others are seeing a problem, I'll spend some time 
isolating it.

Is anyone else seeing this problem?

Eric.
