0:02:58 [ 28/405/2] test_atexit failed
......
beginning 6 repetitions

test_atexit leaked [12, 12, 12] references, sum=36
test_atexit leaked [4, 4, 4] memory blocks, sum=12
Code of of the test:
def test_callbacks_leak(self):
# This test shows a leak in refleak mode if atexit doesn't
# take care to free callbacks in its per-subinterpreter module
# state.
n = atexit._ncallbacks()
code = r"""if 1:
import atexit
def f():
pass
atexit.register(f)
del atexit
"""
ret = support.run_in_subinterp(code)
self.assertEqual(ret, 0)
self.assertEqual(atexit._ncallbacks(), n)
Hum, I don't understand: the test leaks references on purpose?
To reproduce the bug, use the command:
python -m test -R 3:3 -m test_callbacks_leak test_atexit
Note: Leak isolated my bisect_test.py of bpo-29512.
