New submission from Doug Hellmann:
Under python 2 when an atexit callback raised an exception the full traceback
was displayed. Under python 3, only the summary of the exception is shown.
Input file:
import atexit
def exit_with_exception(message):
raise RuntimeError(message)
atexit.register(exit_with_exception, 'Registered first')
atexit.register(exit_with_exception, 'Registered second')
Python 2:
$ python2.7 source/atexit/atexit_exception.py
Error in atexit._run_exitfuncs:
Traceback (most recent call last):
File
"/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/atexit.py",
line 24, in _run_exitfuncs
func(*targs, **kargs)
File "source/atexit/atexit_exception.py", line 36, in exit_with_exception
raise RuntimeError(message)
RuntimeError: Registered second
