Not sure what's exactly going on but pytest-xdist started emitting INTERNALERRORs and failing in version 1.23.1 (and 1.23.2). pytest-xdist-1.23.0 does not emit these.

EDIT: minimal repro:

$ cat test_foo.py
def test_foo():
    open('/dev/null', 'rb')
$ python3.6 -mpytest test_foo.py -W once -n2

To reproduce:

$ python3.6 -mvenv tmp
$ ./tmp/bin/python3.6 -mpip install pytest pytest-xdist six
$ git clone https://github.com/airspeed-velocity/asv.git
$ cd asv
$ git checkout 6f729bb9808116c1ebaa77c6684a4c8120926051
$ ../tmp/bin/python3.6 -mpytest test/test_dev.py -n2

Hi @pv,

I suspect your code emitting a warning which contains a BufferedReader in one of its arguments...

When you run without xdist, do you see any warnings which might fit the bill?

Yes, there are ResourceWarning: unclosed file <_io.BufferedReader name=8> emitted.
But I guess ideally pytest-xdist shouldn't choke on those?

Yes, you are absolutely right.
