I have observed this in both Python 3.7 and Python 3.8. Does anyone have
any insights or suggestions for how to debug this? It seems likely to be
hard to produce a reproducible test case.

is a "common idiom", but not common enough to be
familiar to me and tricky to be inconsistent. But now I know, and the crash
is gone :)

large" by production standards, only by test data
standards. It's about 500kb and not at all deeply nested, basically a long
list of dictionaries. But I don't seem to be able to reduce it further
either.

ish characters in it. It works at least once, and
then crashes on the second or third send of the same data.
I paste the stacktrace from Python 3.7.4 below. Please let me know how I
can debug this further. I'm using Visual Studio 2017 on Windows 10 if that
helps.

OK, I'll do that if nobody points me at some existing docs here.

seems misleading to me, as it is only relevant if writing
to the console. It would be useful to contrast the behaviour with and
without "-u" when writing to files I would say.

ays pick a random one and hope for the best, but I was hoping
someone here might have a tip for one that has been used and debugged
and is likely to work.

I feel certain there must be some way to do this as it seems a rather
basic thing somehow, can anyone give me a hint?

I wonder if there is some standard way to deal with this situation?

Possibly, although for me "logging" is exposed as a module, and ought
to behave as one when requesting the m
is some other way to do that? I can naturally
write my own method to do this but wondered if I'm missing something
here.

Hi all,
I wonder if there are others out there who like me have tried to use
the logging module's configuration file and found it bloated and over-
complex for simple usage (i.e. a collection of loggers writing to
files)
At the moment, if I want to add a new logger "foo" writing to its own
file "
t stdin, stdout and stderr of the child
process to os.devnull then it will wait 10 seconds on Linux also,
which I'd also expect as we can't collect info from these places if
they've been forwarded elsewhere. It seems like Windows somehow
doesn't notice this.
Any help gratefully appreciated.
Regards,
Geoff Bache
