Content
Consider the following: subprocess.run('sleep 10', shell=True, timeout=.1, capture_output=True) It should raise after 0.1 seconds, but it does not - it waits 10 seconds till sleep finishes and only then raises "subprocess.TimeoutExpired: Command 'sleep 10' timed out after 0.1 seconds" Removing 'capture_output=True' or converting command string to list (and removing shell=True) makes it work. I'm using Python 3.7.3 on Ubuntu 16.04. Reproduces on official docker Python 3.7.3 image alpine3.8.
