New submission from Ryder Lewis:
I'm not sure if this is a bug or expected behavior, but basically what I want
to do is log the timestamp when an application exits. Sample script to
illustrate the issue:
==== try.py ====
import time
class A():
def __init__(self):
print("Initializing A. The time is {}".format(time.time()))
def __del__(self):
if time is None:
print("time is None!")
else:
print("Deleting A. The time is {}".format(time.time()))
a = A()
raise SystemExit()
=====
When running this script multiple times, there are 3 possible outcomes:
==== outcome #1 (happens about 25% of my trial runs, what I would expect is
correct behavior) ====
Initializing A. The time is 1400175810.4806361
Deleting A. The time is 1400175810.483156
==== outcome #2 (happens about 50% of my trial runs) ====
Initializing A. The time is 1400175814.1646852
time is None!
==== outcome #3 (happens about 25% of my trial runs) ====
Initializing A. The time is 1400175809.6802816
Exception ignored in: <bound method A.__del__ of <__main__.A object at
0x7fb125eab5f8>>
Traceback (most recent call last):
File "./try.py", line 12, in __del__
TypeError: 'NoneType' object is not callable
