Update installers to Tcl/Tk 8.6.14

[chrstphrchvz]

Tcl/Tk 8.6.14 is out today: https://sourceforge.net/p/tcl/mailman/tcl-core/thread/SA1PR09MB887585E09B30AE57F0E7F2E3865F2%40SA1PR09MB8875.namprd09.prod.outlook.com/#msg58743251

I will open a few PRs for these shortly: one here for the macOS installer, and others at cpython-source-deps for Windows:
python/cpython-source-deps#33
python/cpython-source-deps#34

There is still a known test failure with Tk 8.6.14 which I have neglected: gh-107262

I believe the Windows build needs to be updated to use the new version (PCbuild/get_externals.bat and PCbuild/tcltk.props). @zooba @zware

[zooba]

Yeah, Windows is not done yet. I should have time later today to bring in the new sources and set the build up.

[zooba]

It looks like something has changed in Tkinter as a result of the new version. @terryjreedy is this something you can look into? You can see the build results on #117030

[terryjreedy]

@zooba I have no record or recollection of receiving your Mar 20 note. I just read the release announcement and don't see any problem at least with IDLE. I will do some manual testing after updating. Glad to see update in both 3.13 and 3.14. Fine to leave 3.12 alone.

8.6.14 is a bugfix release, and it can contain changes affecting Tkinter users. https://wiki.tcl-lang.org/page/Changes+in+Tcl%2FTk+8%2E6%2E14

Is there a way for Windows and macOS users to update Tcl/Tk separately? If they can only use the version shipped with Python, we should provide the last stable bugfix release.

Thanks for the reminder, @serhiy-storchaka. This should have been backported earlier to 3.12.x for the macOS installer but I guess I was waiting to see if any issues arose with the 3.13 alphas. PR #119922 will be merged for the upcoming 3.12.4 release.

[aivarannamaa]

The discussion under PR-s is confusing for me, so I'll ask here -- is Tcl/Tk 8.6.14 coming for Python 3.12 Windows installers? 3.12.4 seems to be still with 8.6.13.

There is an error in tkinter.Tk()

This probably means that Tcl wasn't installed properly.

The correct path to search is C:/Python313-64/tcl/tcl8.6. In python 3.12.4 is C:/Python312-64/tcl/tcl8.6 also.

[terryjreedy]

Same binary, some Python commands, Win10, works fine for me.

>>> import tkinter
>>> tkinter.Tk()
<tkinter.Tk object .>

No idea why the difference.

[terryjreedy]

IDLE works normally and reports 8.6.14, as expected.

[marcelotduarte]

I experienced this error using GHA for testing cx_Freeze.
So I installed it in a VM with W11 to test.
The difference may be that I didn't install python for all users, like GH.
The error in GHA:

  This probably means that Tcl wasn't installed properly.

I'm going to go ahead and mark this as complete. For posterity, v3.13.0 shipped with Tcl/Tk v8.6.14 on Windows and macOS; v3.12.4-v3.12.7 have Tcl/Tk v8.6.14 on macOS and v8.6.13 on Windows. v3.13.1 and v3.12.8 will have Tcl/Tk v8.6.15 on both platforms; v3.12.8 will have Tix v8.4.3 as built against Tcl/Tk v8.6.13 on Windows.
