From c55401ba1646202fa36e4973b05dbacaa146cb16 Mon Sep 17 00:00:00 2001 From: Ross Burton Date: Wed, 1 Mar 2017 12:07:44 +0000 Subject: oeqa: add output to subprocess exceptions Out of the box subprocess.CalledProcessError.__str__() just displays the command and exit code, which isn't very useful for debugging. Add a function to oeqa.utils.subprocesstweak to monkey-patch __str__() so that it can also display the value of stdout and stderr.
