[issue31438] IDLE 3 crashes and quits when caret character typed

Terry J. Reedy added the comment:

Glad it is working and thanks for the detail notes.

Ned, is there anything we should change on the web page?  Perhaps emphasize 
more not to upgrade to tcl/tk 8.6?  Is it usual to have to re-install python?

Alper, please do not revert headers after a core dev has changed them.  This 
was never about IDLE, except insofar as IDLE is a victim of the problem.  IDLE 
is a tkinter program and you could have written a tkinter program yourself with 
a similar problem.

[issue31438] IDLE 3 crashes and quits when caret character typed

[ALPER PAKSOY]

ALPER PAKSOY added the comment:

Problem has been solved after installation of ActiveTcl 8.5.18.0 from 
ActiveState's web site as per Terry’s recommendations and, then, reinstallation 
of Python 3.6.2 package from python.org. However, there were many (mis)steps 
per my ignorance and laziness in between. Thank you very much for all the help!

Noteworthy case notes:

1. The previously installed IDLE 3.6.2 as part of the Python 3.6.2 package 
continued crashing whenever I entered the caret character after the 
installation of ActiveTcl 8.5.18.0. I noticed that the IDLE’s Tk version showed 
8.5.9 even after I installed, as recommended, ActiveTcl 8.5.18.0, and rebooted 
my computer. Note that the “info patchlevel” script I executed within tclsh had 
started returning “8.5.18” instead of “8.5.9” after the installation of 
ActiveTcl 8.5.18.0.

2. I could not find a way to make the existing Python / IDLE 3.6.2 installation 
recognise ActiveTcl 8.5.18.0 as the IDLE’s Tk version kept showing 8.5.9. 
Therefore, I  reinstalled the Python 3.6.2 package downloaded from python.org. 
The package made the installation to a new location rather than overwriting the 
existing Python / IDLE 3.6.2 files.

3. The newly installed IDLE 3.6.2 has been working fine without showing any 
signs of instability. There are no crashes when I type the caret character. Its 
Tk version shows 8.5.18 along with the tclsh interpreter. 

4. I removed all the files associated with the “buggy” Python / IDLE 3.6.2 
installation via the terminal window in order to prevent any future confusion 
between the old and new installations.

5. Though I installed ActiveTcl 8.6.6.8606 from ActiveState’s web site in my 
earlier trials, I don’t think I was able to fully test whether this latest Tcl 
really works with Python / IDLE 3.6.2 or not. After installing ActiveTcl 
8.6.6.8606, the “info patchlevel” I executed within tchlsh started returning 
“8.6.6” but the (old) IDLE 3.6.2’s Tk version still showed 8.5.9. I, then, 
installed ActiveTcl 8.5.18.0 after uninstalling ActiveTcl 8.6.6.8606 as a 
precaution. It  occurred to me that I may need to reinstall the Python 3.6.2 
package from python.org only after installing the ActiveTcl 8.5.18.0.

[issue31438] IDLE 3 crashes and quits when caret character typed

[Terry J. Reedy]

Terry J. Reedy added the comment:

If your installed Python with the 64/32 Mac installer from python.org, follow 
the instruction, on the link given, to install Active 8.5.18 and *not* 8.6.  I 
believe the issue is that the _tkinter binary is compiled to work with 8.5, not 
8.6.

If you used any other installer, talk with its providers.

Ned, is 3.6.2 tkinter on Mac supposed to work with tcl/tk 8.6.6?

I downloaded and installed TCL 8.6.6.8606 and restarted my computer. I verified 
that the new version was installed. Unfortunately the problem has not been 
solved. Thank you.

In the future, please upload plain text.  I am fairly certain that this is a 
duplicate of previous issues about Apple's buggy tcl/tk causing crashes  that 
bypass Python's error reporting.

[issue31438] IDLE 3 crashes and quits when caret character typed

[ALPER PAKSOY]

New submission from ALPER PAKSOY:

IDLE 3 crashes and quits whenever I type the caret (^) character in the editor. 
I have to copy and paste the caret character into the IDLE editor whenever I 
have to use the caret character. I have the IDLE 3.6.2 running on macOS Sierra 
(v10.12.6) on mid-2011 27" iMac. Attached is an example  error log generated 
when IDLE 3 crashes after the typing of the caret character.
