test_tkinter failing on MacOS #128846DescriptionBug report
Bug description:
test_tkinter is failing on MacOS (Sequoia 15.2, M1 MacBook Pro, in my case). It was working fine yesterday, so without delving into this too deeply, I'm going to suggest this change overnight broke things. See attached log
commit da8825ea95a7096bb4f933d33b212a94ade10f6e

gh-128562: Fix generation of the tkinter widget names (GH-128604)
There were possible conflicts if the widget class name ends with a digit.
@Xiaokang2022
(FWIW, test_ttk is failing for me on 3.13, but not main. It appears to be a different problem.)

Activityzanieb commented on Jan 14, 2025 zanieb commented on Jan 14, 2025 I can reproduce this on main / f7ceb31 but reverting da8825e does not resolve the failure. zanieb commented on Jan 14, 2025 I also reproduced this on an arbitrary older commit 2fcdc84 (and then b2ac70a)
If I go back to ce740d4, which I need to run the GUI tests on my machine, I get a bunch of failures — including what looks like the failures reported here. @smontanaro I don't know if it makes sense that these tests worked yesterday. zanieb commented on Jan 14, 2025 It looks like this is caused by using tk 9.0+, at least on my machine, Brew upgraded to a new version.
You can confirm with
❯ ./python.exe -c 'import tkinter; tcl = tkinter.Tcl(); print(tcl.call("info", "patchlevel"))'
9.0.1
In which case, this is part of
I don't think the tests are expected to pass with tk 9 yet. smontanaro commented on Jan 14, 2025 ContributorAuthor More actions Hmmm... This might turn out to be pilot error. I have a config file in my personal build environment which gets Tcl/Tk libs from my Conda env:
TCLTK_CFLAGS=-I/Users/skip/miniconda3/envs/python312/include
TCLTK_LIBS='-L/Users/skip/miniconda3/envs/python312/lib -Wl,-rpath,/Users/skip/miniconda3/envs/python312/lib -ltk8.6 -ltkstub8.6 -ltcl8.6 -ltclstub8.6'
Somehow that was dropped from a command recalled from my bash history, so I was picking up 9.0.1. Now that I've corrected my commands, my build on main works and yields the expected version:
% ./python.exe -c 'import tkinter; tcl = tkinter.Tcl(); print(tcl.call("info", "patchlevel"))'
8.6.13
I've yet to pull in the correct command on my 3.13 Terminal window, so it still yields the later version:
% ./python.exe -c 'import tkinter; tcl = tkinter.Tcl(); print(tcl.call("info", "patchlevel"))'
9.0.1
Would it be worthwhile running this bit of code in the test suite, then skipping the tests if Tcl/Tk v9 was found? zanieb commented on Jan 14, 2025 That seems reasonable to me, but I'd be curious to hear from someone that's a stakeholder for that topic. sobolevn commented on Jan 15, 2025 Xiaokang2022 commented on Jan 15, 2025 This doesn't seem to be the cause of my commit, which passed macOS-related tests. terryjreedy commented on Jan 15, 2025 @serhiy-storchaka is the tkinter expert, not me. I would like to be able to use 9.0, but I don't know where that stands now. warsaw commented on Jul 9, 2026 FWIW, I see test_tkinter blocking unrelated 3.13 backports, pretty consistently. On a local 3.13 branch, both test_tkinter and test_ttk fail for me consistently too.

For me, they pass on all newer branches. serhiy-storchaka commented on Jul 9, 2026 test_wm_iconbitmap has separate issue #146531. Other failures are not related to it.
The original report was 1.5 years ago, there were many changes in tests since then, especially in last month. Please check if the originally reported failure still reproduced (besides test_wm_iconbitmap). I have no Mac, so my capabilities to address Mac-only issues are limited. warsaw commented on Jul 9, 2026 @hugovk "fixed" the timeout, but I still see two actual failures:
