[issue34609] Idle Unitest

[Cheryl Sabella]

Cheryl Sabella  added the comment:

Following up, I was able to recreate under 3.8 using pdb in powershell, so it's 
not just in IDLE.

Traceback (most recent call last):
  File "N:\projects\cpython\lib\pdb.py", line 1697, in main
pdb._runscript(mainpyfile)
  File "N:\projects\cpython\lib\pdb.py", line 1566, in _runscript
self.run(statement)

Cheryl Sabella  added the comment:

Just to help track this down, 'import math' does not cause the trace, but 
'import email' does.  It seems to be modules that have a loader function.  My 
guess (but I haven't tried it yet) is that this would happen if stepping 
through pdb outside of IDLE too.

Cheryl Sabella  added the comment:

I have Python 3.6.5 on Ubuntu 18.04.  Initially, I was unable to recreate the 
issue.  However, issue33065 from 4 months ago has the same trace (except on a 
different import), so I tried stepping through debug using the minimal example 
that Terry gave and successfully reproduced the trace.

I then tried a new build of 3.8 on Ubuntu and was also able to reproduce by 
using 'step' while in debug.

I also was able to recreate using 'step' under 3.6.3 on Windows 7.

Note: At one point while stepping, the debug window shows a KeyError on 
unittest.  You'll see it yourself, but it is interesting.

Tal Einat  added the comment:

Testing similarly to Terry, this doesn't reproduce with a recent build of 
master branch (3.8) on Ubuntu 16.04.

I'll be able to try a build of older versions with IDLE only in a few days.

[issue34609] Idle Unitest

[Terry J. Reedy]

Terry J. Reedy  added the comment:

I cannot confirm this.  I tested 3.6.6 on Windows 10 with tem3.py containing

import unittest
print unittest

I ran this twice, without and with debug on.  The output:

 RESTART: F:\Python\a\tem3.py 

>>> 
[DEBUG ON]
>>> 
 RESTART: F:\Python\a\tem3.py 

[DEBUG ON]
>>>

On the second run, I hit the [Go] button on Debug Control.  The minimal program 
above needs to be tested with 3.6.6 or 3.7.0 on Linux.
