To elaborate a bit: the OP, while angry, produced both a
detailed
analysis *and* a PR. It's normal to be angry when an
advertised
feature doesn't work and it makes you lose hours of work
(or, even,
forces you to a wholesale redesign). Producing a
detailed analysis and a
PR is more than most people will ever do.
His *other* email seems reasonable, and warrants a response,
yes. But
are we to take the suggestion made here (to drop tkinter)
seriously,
based on the fact that there's a (rare - at least it appears
that the
many IDLE users haven't hit it yet) race condition that
causes a crash
in Python 2.7? (It appears that the problem doesn't happen
in the
python.org <http://python.org> 3.x builds, if I understand
the description of the issue).
In 3.x, Tkinter+threads is broken too, albeit in a different way --
see https://bugs.python.org/issue33412
<https://bugs.python.org/issue33412> (this should've been the 2nd
link in the initial message, sorry for the mix-up).
The observation in that issue that tkinter and threads should be
handled in specific ways is certainly a given for old hands, who have
long put the GUI code in one thread with one or more concurrent worker
threads typically communicating through queues. But I haven't built
anything like that recently, so I couldn't say how helpful the current
documenation might be.
Interacting with the GUI only in the main thread is something that I've
had to do in other languages (it is/was the recommended practice), so I
naturally do the same with Python and tkinter. It's also easier to
reason about because you don't get elements of the GUI changing
unexpectedly.
