Subject: [PATCH v2 3/6] python/machine: use subprocess.run instead of subprocess.Popen
Date: Mon, 17 May 2021 14:48:05 -0400 [thread overview]
Message-ID: <20210517184808.3562549-4-jsnow@redhat.com> (raw)
In-Reply-To: <20210517184808.3562549-1-jsnow@redhat.com>
use run() instead of Popen() -- to assert to pylint that we are not
forgetting to close a long-running program.
Signed-off-by: John Snow <jsnow@redhat.com>
