I think this can still result in a orphaned process; if the
process.terminate() on the line above is successful, the process will
exit and then process.kill() here will raise an exception and will
call wait. This is true generally everywhere; wait() must be called
regardless of if kill() successed, because kill() will fail if the
process is already dead. It's a little tricky because
process.commuinicate() calls wait(), so you can't unconditionally call
wait(), but my solution was to remove all the kill() and wait() calls
that already exist and add:
try:
run()
except:
logger.debug(....)
raise
finally:
if process.returncode is None:
try:
process.wait(timeout=5)
except TimeoutExpired:
try:
process.kill()
except OSError:
pass
process.wait()
