From 578c8205fd14c48c6d30ef2889d86f1b4aee060a Mon Sep 17 00:00:00 2001 From: Mikko Rapeli Date: Thu, 22 Jun 2017 16:23:14 +0300 Subject: meta: Fix return value checks from subprocess.call()'s Python function subprocess.call() returns the return value of the executed process. If return values are not checked, errors may go unnoticed and bad things can happen. Change all callers of subprocess.call() which do not check for the return value to use subprocess.check_call() which raises CalledProcessError if the subprocess returns with non-zero value. https://docs.python.org/2/library/subprocess.html#using-the-subprocess-module All users of the function were found with: $ git grep "subprocess\.call" | \ egrep -v 'if.*subprocess\.call|=\ +subprocess\.call|return.*subprocess\.call' Tested similar patch on top of yocto jethro. Only compile tested core-image-minimal on poky master branch.
