From 748356ff34899ce74d3d682e13d05b8bc2bc05e3 Mon Sep 17 00:00:00 2001 From: Bruce Ashfield Date: Thu, 28 Sep 2017 11:59:09 -0400 Subject: cml1: remove diffconfig return code checking The following commit: [ commit 578c8205fd14c48c6d30ef2889d86f1b4aee060a Author: Mikko Rapeli Date: Thu Jun 22 16:23:14 2017 +0300 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. Signed-off-by: Mikko Rapeli Signed-off-by: Ross Burton Signed-off-by: Richard Purdie ] Added return code checking to do_diffconfig. Although the change is well intentioned, it isn't correct in this instance since 'diff' returns '1' to indicate that there are differences in the files .. and not as an error code. subprocess.check_call() flags this as an error and the routine aborts. We are already checking the inputs, and in fact already know there's a diff in the files before we even make the call, so there's no need to look for an error in this case. Putting back subprocess.call() restores the routine to working order.
