From: Ed Bartosh Date: Wed, 4 May 2016 13:06:25 +0000 (+0300) Subject: wic: decode output of subprocess.communicate X-Git-Tag: uninative-1.0~17 X-Git-Url: https://code.ossystems.io/gitweb?a=commitdiff_plain;h=5b556f58a171e3d45107bb56a1f780e5c1abba37;p=openembedded-core.git wic: decode output of subprocess.communicate stdeout and stderr content returned by communicate API has different types in Python 3(bytes) and Python 2(string). Decoding it to 'utf-8' makes it unicode on both pythons. Decoded stdout and stderr output to utf-8 to make the code working under both Python 2 and Python 3.
