New submission from Ronal Abraham <ronalabra...@gmail.com>:
There doesn't appear to be a way to prematurely kill a subprocess using the high-level asyncio subprocess APIs (https://docs.python.org/3.9/library/asyncio-subprocess.html) without getting a traceback on exit. On exit, the attached program writes the following to stderr: $ python3.9 kill_subprocess.py Exception ignored in: <function BaseSubprocessTransport.__del__ at 0x1065f0dc0> Traceback (most recent call last): ... raise RuntimeError('Event loop is closed') RuntimeError: Event loop is closed If I uncomment `# process._transport.close()` or comment `asyncio.sleep(1)`, the walkback disappears. (I get the same behavior in python 3.8. I haven't tried other python versions.) ---------- components: asyncio files: kill_subprocess.py messages: 391349 nosy: asvetlov, rabraham, yselivanov priority: normal severity: normal status: open title: Cannot cleanly kill a subprocess using high-level asyncio APIs type: behavior versions: Python 3.8, Python 3.9 Added file: https://bugs.python.org/file49965/kill_subprocess.py _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue43884> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
