[issue18746] test_threading.test_finalize_with_trace() fails on FreeBSD buildbot
STINNER Victor added the comment: I don't see this issue anymore on FreeBSD buildbots. It was probably fixed.

[issue18746] test_threading.test_finalize_with_trace() fails on FreeBSD buildbot
koobs added the comment: I'm not sure if this issue is/was related, but it seems the commit addressing #18178 has taken care of the test_finalize_runnning_thread failure. I note that your description specifies test_finalize_with_trace, perhaps suggesting your reproduction case may be something slightly different? FWIW, I don't think I've seen the 'with_trace' test fail on my buildbots (but correct me if I'm wrong) After the commit mentioned above, the FreeBSD 10 buildbot is now green on all branches. -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue18746 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue18746] test_threading.test_finalize_with_trace() fails on FreeBSD buildbot
New submission from STINNER Victor:
The following test fails on FreeBSD buildbot:
def test_finalize_with_trace(self):
# Issue1733757
# Avoid a deadlock when sys.settrace steps into threading._shutdown
assert_python_ok(-c, if 1:
import sys, threading
# A deadlock-killer, to prevent the
# testsuite to hang forever
def killer():
import os, time
time.sleep(2)
print('program blocked; aborting')
os._exit(2)
t = threading.Thread(target=killer)
t.daemon = True
t.start()
# This is the trace function
def func(frame, event, arg):
threading.current_thread()
return func
sys.settrace(func)
)
I ran it manually on my FreeBSD 9.1 VM, I get the following error. I don't know
if it's the same error than the buildbot.
(...)
# clear builtins._
(...)
# restore sys.stderr
# cleanup __main__
# cleanup[1] _sysconfigdata
(...)
# cleanup[1] threading
Exception ignored in: function WeakSet.__init__.locals._remove at
0x801b11058
Traceback (most recent call last):
File /usr/home/haypo/prog/python/default/Lib/_weakrefset.py, line 38, in
_remove
File x.py, line 17, in func
AttributeError: 'NoneType' object has no attribute 'current_thread'
# cleanup[1] _weakrefset
(...)
# cleanup[3] _codecs
PyThreadState_Clear: warning: thread still has a frame
The weakref is probably threading._dangling.
IMO Py_Finalize() should first clear the trace function. Tracing Python
exception while Python is dying (exiting) is insane. I'm surprised that it
works :-)
