_tkinter.TclError: integer value too large to represent

This bug looks similar to issue25263.

The compile step mentions Tk version 8.6.4.2:

"tk-8.6.4.2 already exists, skipping."

It seems like the test never fails on 3.6, while 3.6 contains the fix b9d672491d5082c541bf267eb7bb99fdc6529324. Let's try to backport this change to 3.5 and 2.7 branches.

See also bpo-16840.

Thank you for backporting the fix. Seems I just forgot about this.

> Thank you for backporting the fix. Seems I just forgot about this.

The bug wasn't notice before since test_tk fails once, but then pass
when run again... It fails randomly. But I noticed a warning on a
build, and so saw the bug. More stable buildbots should help to catch
more random bugs.

I backported fixes to 2.7 and 3.5 branches. The test fails randomly, so I close the issue and hope that it doesn't come back.

If it comes back on 3.5, we should now get the identifier which caused the failure. I will reopen the issue if the bug occurs again.

Change the Python version to 2.7 only, since Python 3.5 doesn't accept bug fixes anymore (only security fixes).

I didn't see this failure since one month on the 2.7 buildbots. While I fear that the bug still exists, I close it to clean up my list of open issues. I will reopen the issue if the bug strikes back!

Too bad, the bug is not dead:

In Python 2 hex() adds the 'L' suffix for longs.

I'm not 100% sure that this build really tested the commit fbdd3eeba3e526e162f2eb54d224cf36ed8cfea1. We had an issue on the buildbot, the 2.7 builder was disabled.

Ah, this is Cygwin!

This is a Tk bug (https://core.tcl.tk/tk/tktview?name=5ee8af61e5ef8e233158a43459624f4ecf58a6fe). It was fixed, but not completely. The fix doesn't work on Cygwin.

> Ah, this is Cygwin!

Hmm, no; Cygwin isn't installed on ware-win81-release.

When was the fix made?  2.7 on Windows currently uses 8.5.15, we can bump it up to latest 8.5 if that will help.

The fix was made 2015-11-09. The tag core-8-5-15 was created 2013-09-16.

I'm not well experienced with fossil and thought that 8.5.15 contains this fix, but now I see that this is not true. Yes, updating Tcl/Tk can help.

If you'd like to do that update, there are some instructions at https://github.com/python/cpython-source-deps.  You can get AppVeyor to use dependencies from your fork of `cpython-source-deps` by adjusting PCbuild/get_externals.bat:32 to point to your username temporarily.

If you don't want to mess with it, I'll get to it sooner or later :)

I manually cleared `externals\tcltk64` on that bot some time ago, and it appears to be happy now.

I think so :)
