New submission from Amber Wright <ambw...@gmail.com>:
The return code of python on linux/MacOS when the program is ended with a KeyboardInterrupt should be -2, when running with multiprocessing the exitcode is 1. I've attached a reproduced example. >From The Process.join() docs: >https://docs.python.org/3/library/multiprocessing.html#multiprocessing.Process.exitcode > A negative value -N indicates that the child was terminated by signal N. output: $ /usr/local/opt/python@3.9/bin/python3 -m test Traceback (most recent call last): File "/usr/local/Cellar/python@3.9/3.9.6/Frameworks/Python.framework/Versions/3.9/lib/python3.9/runpy.py", line 197, in _run_module_as_main return _run_code(code, main_globals, None, File "/usr/local/Cellar/python@3.9/3.9.6/Frameworks/Python.framework/Versions/3.9/lib/python3.9/runpy.py", line 87, in _run_code exec(code, run_globals) File "/Users/awright/docker/2108/test.py", line 49, in <module> sys.exit(main()) File "/Users/awright/docker/2108/test.py", line 41, in main return target() File "/Users/awright/docker/2108/test.py", line 10, in target time.sleep(99999) KeyboardInterrupt proc.wait()=-2 Process SpawnProcess-1: Traceback (most recent call last): File "/usr/local/Cellar/python@3.9/3.9.6/Frameworks/Python.framework/Versions/3.9/lib/python3.9/multiprocessing/process.py", line 315, in _bootstrap self.run() File "/usr/local/Cellar/python@3.9/3.9.6/Frameworks/Python.framework/Versions/3.9/lib/python3.9/multiprocessing/process.py", line 108, in run self._target(*self._args, **self._kwargs) File "/Users/awright/docker/2108/test.py", line 10, in target time.sleep(99999) KeyboardInterrupt proc.exitcode=1 See also: https://bugs.python.org/issue1054041 and https://bugs.python.org/issue41602 ---------- components: Interpreter Core files: test.py messages: 400384 nosy: ambwrig priority: normal severity: normal status: open title: Python doesn't exit with proper resultcode on SIGINT in multiprocessing.Process versions: Python 3.10, Python 3.11, Python 3.8, Python 3.9 Added file: https://bugs.python.org/file50237/test.py _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue45023> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
