Issue 7596: test_logging sometimes fails (original) (raw)

test_logging sometimes fails with the following error, e.g. on the buildbots (*):

Error in atexit._run_exitfuncs: Traceback (most recent call last): File "/home/buildbot/cpython-ucs4/trunk.pitrou-ubuntu-wide/build/Lib/atexit.py", line 24, in _run_exitfuncs func(*targs, **kargs) File "/home/buildbot/cpython-ucs4/trunk.pitrou-ubuntu-wide/build/Lib/logging/init.py", line 1556, in shutdown h.flush() AttributeError: 'NoneType' object has no attribute 'flush' Error in sys.exitfunc: Traceback (most recent call last): File "/home/buildbot/cpython-ucs4/trunk.pitrou-ubuntu-wide/build/Lib/atexit.py", line 24, in _run_exitfuncs func(*targs, **kargs) File "/home/buildbot/cpython-ucs4/trunk.pitrou-ubuntu-wide/build/Lib/logging/init.py", line 1556, in shutdown h.flush() AttributeError: 'NoneType' object has no attribute 'flush' [874213 refs]

I can reproduce this on OS X 10.6 with:

./python.exe Lib/test/regrtest.py test_lib2to3 test_logging

Same here! The failure report in verbose mode is:
