[issue5673] Add timeout option to subprocess.Popen
Pablo Bitton added the comment: I've been using the subprocess-timeout-v5.patch patch with 2.x. Isn't that version supposed to work with 2.x? Other than the stated problem, the patched module generally works, and is very helpful. -- ___ Python tracker <http://bugs.python.org/issue5673> ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
[issue5673] Add timeout option to subprocess.Popen
Pablo Bitton added the comment:
I'd like to report a problem I encountered with the discussed use pattern using
subprocess-timeout-v5.patch on linux. I don't have python3 installed at work,
sorry.
When running:
p = subprocess.Popen("tcpdump -i eth0 > file &", stdin=subprocess.PIPE,
stdout=subprocess.PIPE, stderr=subprocess.PIPE, shell=True,
universal_newlines=True)
try:
out, err = p.communicate(timeout=1)
except subprocess.TimeoutExpired:
p.kill()
out, err = p.communicate()
After the timeout happens, the last line raises a ValueError: I/O operation on
closed file.
The exception is thrown from the register_and_append call for self.stdout in
_communicate_with_poll. I'm sorry again for not being able to attach the full
traceback.
The problem doesn't reproduce without the '&' or the '> file', and doesn't
reproduce with other executables I've tried.
