From 68190b511531886f498a3cf57f9ad7fb126d5fcb Mon Sep 17 00:00:00 2001 From: Markus Lehtonen Date: Fri, 24 Mar 2017 16:43:24 +0200 Subject: oeqa.utils.commands: limit runCmd exception output Make it possible to limit the length of output lines shown in runCmd exceptions. E.g when running bitbake we easily get thousands of lines of log output, where only the last few (tens) are interesting or relevant when an error occurs.
