From 0b95ff72cb42567dd71685bfdafbcdcd9784ea83 Mon Sep 17 00:00:00 2001 From: Fam Zheng Date: Wed, 12 Jul 2017 15:55:28 +0800 Subject: [PATCH] docker.py: Improve subprocess exit code handling MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit A few error handlings are missing because we ignore the subprocess exit code, for example "docker build" errors are currently ignored. Introduce _do_check() aside the existing _do() method and use it in a few places.
