Hello,
I've got a Python program that does client COM programming on Windows, for Excel and National
Instruments TestStand.
When I convert it to a Windows EXE file with cx_Freeze, at exit, I get a
message like this:
Exception KeyError: KeyError(2768,) in <module 'threading' from '<frozen>'>
ignored
It seems not to be an exception; rather some sort of debug message that I can't get rid of--a
little unusual.
Any ideas why this might be happening? I assume it is something to do with a COM-related thread
not finishing "correctly" at exit. The number quoted in the KeyError appears likely to be a
Windows process/thread ID. This message doesn't occur when running the original Python program;
only when running the cx_Freeze-generated EXE.
This is using cx_Freeze 4.1.2 with Python 2.6.5 on Windows 2000.

This may be related:
http://bugs.python.org/issue1596321
But I'm not sure what might be a good work-around when using cx_Freeze.

I found that a very basic Python program that does nothing except `import threading` causes this
message.
(I had hoped that `import threading` in the main program might be a work-around, after reading the
comments on the Python bug report linked above. My program originally didn't import threading
directly, but evidently uses it indirectly for win32com COM client programming.)

I looked at the source code, and found that in the initscripts/Console.py--
http://cx-freeze.svn.sourceforge.net/viewvc/cx-freeze/trunk/initscripts/Console.py?revision=205&view=markup
--there are the following lines:
if sys.version_info[:2] >= (2, 5):
module = sys.modules.get("threading")
if module is not None:
module._shutdown()
If these lines are commented-out, then the error message at exit does not occur.
Why are those lines there, and what is the consequence of me removing them?

Craig McQueen
