For some reason the recently added test_ttk_guionly is causing Tcl to
abort on Mac. I would prefer to disable the test for now, except if some
mac owner has the time to fix it.

I would like to know the tcl version being used on the noller-osx86
buildslave too, if possible.

Just saw it didn't cause an abort with the buildslave heller-x86-osx5, btw.

It seems to be good now after a recent modification in how tests are
performed, closing. Sorry for the fuss.

The abort still happens occasionally, see:
http://www.python.org/dev/buildbot/all/OS%20X%20x86%20trunk/builds/118/step-test/0
(last lines)

I've talked with Daniel Steffen, who is one of the maintainers of Tcl/Tk
on Mac OSX, and I was told that all this conditional code in _tkinter.c
and tkappinit.c for TK_AQUA is outdated starting with tk 8.4.8, but tk
8.4.7 that ships with macosx (which happens to be the version being used
by the buildslave mentioned above) also includes the patch that
deprecates the usage, and we should be calling only Tk_Init on
tkappinit.c which will deal with all the details (the details are in
tkMacOSXInit:TkpInit).

There is an entry in tk's changelog that is directly related to this:
http://tktoolkit.cvs.sourceforge.net/viewvc/tktoolkit/tk/ChangeLog.2004?revision=1.1&view=markup
(lines 210-220)

Any chance I can change _tkinter and tkappinit to check for
TKINTER_OLD_AQUA (new macro to be added) instead of TK_AQUA and verify
if it helps the buildslaves ?

To follow up your question posted on issue 6527 (sorry for the
duplicate), I don't currently have a mac to test on.  I might have
access to one in a couple weeks, though.

I noticed this while investigating Issue6834. Is this still an open issue 
for OS X?  Could it explain the symptoms in 6834?

Sorry, that should be Issue6864.

Is this still a problem on OS X?

Mark: maybe, why don't you test this?

This is still an issue for the PPC Tiger buildbot:

test_ttk_guionly
make: *** [buildbottest] Segmentation fault

(Direct link: http://www.python.org/dev/buildbot/builders/PPC%20Tiger%202.7/builds/39/steps/test/logs/stdio)

Presumably this is the same issue 8716.  That issue contains additional details and a patch from Ronald, so I'm not closing it as a duplicate.  

I don't know if the patch on this issue would actually address the issue.  I tried to apply it to py3k but it did not apply cleanly.

ttk_guionly creates a button (ttk.Button()) which calls _load_tile(), which crashs on: master.tk.eval('package require tile')

Can anyone with a Mac look at this issue?

See comments to Issue8716. Suggest any further comments on the "headless" crash issue go there and reserve this issue for investigation into the suggested changes to initialization when using Aqua Tk.  BTW, the supplied patch has compile time Tk version tests which can be problematic since Aqua Tk is dynamically linked and so the exact patch version cannot be determined at compile time.  However, since 8.4.7 is the earliest version we claim to support we could probably dispense with the check, assuming the change is warranted.

As mentioned by Ned this is a duplicate of #8716. 

The proposed change to tkinter initialization in msg81468 might be useful to look into, but I'm not interested in doing that work because I don't use Tkinter myself which makes it harder to test if the change actually helps.

FWIW, the patch looks sane for what it is trying to accomplish.

NOTE: If the Tk version in OSX 10.4 is new enough to not need the workaround that will be disabled by the TKINTER_OLD_AQUA in the patch we could just drop the code.

Can we close this?  I expect that if crashes were still happening from this cause, there would be a newer issue.

Or should this be marked for 3.11?
