[New-bugs-announce] [issue44282] IDLE: ColorDelegatorTest test_incremental_editing failures

[Terry J. Reedy]

New submission from Terry J. Reedy <tjreedy at udel.edu>:

idlelib.idle_test.test_colordelagator.ColorDelegatorTest.test_incremental_editing has failed on at least on the following machines.  

Pip32  CI Pipelines Win32
Gen3x  https://buildbot.python.org/all/#/builders/464  x86 Gentoo Installed with X 3.x
GenPR  https://buildbot.python.org/all/#/builders/465  x86 Gentoo Installed with X PR

Failures seen.  Since tests are sequential without subtesting, failure means successors are not tested.

line  keyword start       want            got  
569   ('BUILTIN', '1.0'), ('1.0', '1.3')  ()              Gen3x, x3; GenPR
573   ('BUILTIN', '1.0'), ('1.0', '1.3')  ()              Gen3x, x5
586   ('BUILTIN', '1.0'), ('1.0', '1.3')  ()              GenPR
597   ('KEYWORD', '1.0'), ()              ('1.0', '1.1')  Pip32, x2

As far as I can tell, looking at Windows buildbots, the 1 failure on Win32 has not been repeated.  If there have been any on CI machines, I have not been informed.

A few years ago, I believe Gentoo was the only *nix buildbot running tkinter and IDLE tests. It has a problem with a builtin at the beginning of the line about 10-20% of test runs.  This are the majority of its failures in the last week.  Perhaps there is a timing issue we can fix.
