[issue37833] tkinter crashes macOS in the latest macOS update 10.14.6

Ronald Oussoren  added the comment:

The py2app issue I mentioned is not relevant for this issue. 

A simple tkinter runs fine with Python 3.7 (64-bit, 3.7.4, Python.org 
installer), the same script causes a WindowServer crash (SEGV) when bundled 
with py2app. 

This is definitely a bug in macOS, the WindowServer should not crash like this 
even if an app is misbehaving. 

I'm therefore changing the status of this issue to closed/third party.

Ronald Oussoren  added the comment:

Interestingly enough both users in the py2app issue I mentioned use the 
python.org installer to install Python.  

One of them mentions this only happens when py2app is used, and that the script 
works fine outside of an app.

I'll look into this tonight (CEST).

Ned Deily  added the comment:

OK, thanks, Ricardo. Since you appear to be using an Anaconda-supplied Tk, I 
suggest you open an issue or otherwise ask for help from the Conda project and, 
as necessary, the Tk folks.  Without more info and unable to reproduce with 
other sources of Tk, there is next to nothing we can do here and the chances 
that this is a Python problem, rather than a Tk or macOS problem, is very slim.

Thanks! I was just looking how to send you all this info, so here it is:

tkinter.TK_VERSION: 8.6
tkinter.info_patchlevel: 8.6.8

$ python3.7 -c 'import _tkinter;print(_tkinter.__file__)'

$ otool -L $(python3.7 -c 'import _tkinter;print(_tkinter.__file__)')

[Ned Deily]

Ned Deily  added the comment:

As far as I know, the best information you can get from Tk about version is the 
patch level which does not necessarily take into account builds from a dev repo 
or patched source.  The easiest way to get that info from tkinter is to use 
test.pythoninfo:

$ python3.7 -m test.pythoninfo
[...]
tkinter.TCL_VERSION: 8.6
tkinter.TK_VERSION: 8.6
tkinter.info_patchlevel: 8.6.8
[...]

It may also be useful to ascertain which Tk libraries tkinter is linked with:

$ python3.7 -c 'import _tkinter;print(_tkinter.__file__)'
/Library/Frameworks/Python.framework/Versions/3.7/lib/python3.7/lib-dynload/_tkinter.cpython-37m-darwin.so

$ otool -L $(python3.7 -c 'import _tkinter;print(_tkinter.__file__)')
/Library/Frameworks/Python.framework/Versions/3.7/lib/python3.7/lib-dynload/_tkinter.cpython-37m-darwin.so:
/Library/Frameworks/Python.framework/Versions/3.7/lib/libtcl8.6.dylib 
(compatibility version 8.6.0, current version 8.6.8)
/Library/Frameworks/Python.framework/Versions/3.7/lib/libtk8.6.dylib 
(compatibility version 8.6.0, current version 8.6.8)
/usr/lib/libSystem.B.dylib (compatibility version 1.0.0, current 
version 1197.1.1)

A followup question: How can I determine the exact version of Tk?

Ronald Oussoren  added the comment:

I had a similar problem during EuroPython, but that was when I had anaconda on 
my machine. I've since removed it because generally don't use it but had it 
installed for a training session.

I haven't tried to reproduce, but also don't run 10.14.6 yet (holding of 
rebooting due to too much active Terminal windows). I'll try to reproduce later 
this week on another machine.

I get reports about this in the py2app repo as well, see 
,
 so this is not just something on a single machine.

Hard to say what is going on without knowing more about the specific version of 
Tk (not just 8.6, but 8.6.8? 8.6.9?).

Thanks for the link but that really doesn’t pin down exactly what Tk is in use. 
This probably should be pursued with the Tk project. Adding Kevin Walzer from 
Tk: Kevin, does this problem sound familiar?

Ricardo Smits  added the comment:

I am on a Conda environment with Python 3.7.4 with the corresponding
Tkinter 8.6 that came with it. I tried to use some apps I compiled with
Pyinstaller and all of them caused this crash. So I tried line by line on
the terminal (to cross out Pyinstaller as the problem) and "root = tk.Tk()"
was where it crashed for me.

Here are more people with the same issues:
https://github.com/pyinstaller/pyinstaller/issues/4334

As Ronald said, most certainly it is a macOS bug, but I don't think they
will bother to fix this when they are so close to their 10.15 release :/

Ned Deily  added the comment:

Can you be more specific about the source of your Pythons and Tk 8.6 and 
exactly what version it is? Tk through tkinter seems to work as expected (and 
without a crash) when I try the current Python.org pythons with their built-in 
Tk 8.6.6 or current MscPorts Pythons with their Tk 8.6.9 all running on the 
latest released 10.14.6 with Supplemental Update on a MacBook Pro.

Ronald, are you able to reproduce this?

This is almost certainly a bug in macOS. I wonder if it is possible to work 
around it in Python.

[issue37833] tkinter crashes macOS in the latest macOS update 10.14.6

[Ricardo Smits]

New submission from Ricardo Smits :

tkVersion == 8.6

After the new update in macOS (10.14.6):

In any python interpreter, when running tk.Tk() it makes macOS crash and logout 
giving the following error:
$ CGSTrackingRegionSetIsEnabled returned CG error 268435459
$ HIToolbox: received notification of WindowServer event port death.
