pytest-xdist fails when running same tests several times

[cooraz]

Hi
I am having an issue with py.test xdist.
I have a PC running the socketserver.py with Loop = True to allow multiple tests, but this seems to be an issue.
When I run a simple test case like:

import time, pytest

def f():
    return 3

def test_f():
    assert f() == 4

using the command line:
py.test -d --tx socket=ip-of-pc:8888 --rsyncdir Testpackage Testpackage
The first executing will return the result, as expect. However, if the same line is executed again, py.test will fail with the following error message:

=================================== ERRORS ====================================
_______________________ ERROR collecting test_script.py _______________________
import file mismatch:
imported module 'Testpackage.test_script' has this __file__ attribute:
  /home/user1/Downloads/pyexecnetcache/Testpackage/test_script.py
which is not the same as the test file we want to collect:
  /home/user1/Downloads/pyexecnetcache/pyexecnetcache/Testpackage/test_script.py
HINT: remove __pycache__ / .pyc files and/or use a unique basename for your test
 file modules
=========================== 1 error in 0.22 seconds ===========================

The package struct is:

Testpackage
   |-     __init__py 
   |-    test_script.py

It seems like the socketserver doesn't do any cleanup, after the test has finished.

I have tried to delete the pyexecnetcache(put in trash) after the first test run, but this gives a similar result:

=================================== ERRORS ====================================
_______________________ ERROR collecting test_script.py _______________________
import file mismatch:
imported module 'Testpackage.test_script' has this __file__ attribute:

e/test_script.py

My client PC is running Linux, but it is a problem on windows too.
Im running py.test 2.9.2 and xdist 1.14

Might be caused by #3968?

closing this as upstream issue with execnet socket servers, pytest cant fix that
