From 22078d5e533e59a9aa6999abefbf6ece4e01de8d Mon Sep 17 00:00:00 2001 From: Christopher Larson Date: Fri, 31 Jul 2015 11:16:46 -0700 Subject: bitbake: bb.parse: properly error out on filesystem errors We've had a long-standing bug where a legitimate error reading a file (IOError or OSError) is always suppressed as though it was a 'file not found' case. As a concrete example, if you do a `chmod 000 conf/local.conf`, it'll silently not parse local.conf, rather than erroring to let the user know about the problem. Fix this by handling the ENOENT case specifically.
