Subject: [PATCH 1/1] python/machine: Change default timeout to 30 seconds
Date: Mon, 20 Jul 2020 12:02:52 -0400 [thread overview]
Message-ID: <20200720160252.104139-2-jsnow@redhat.com> (raw)
In-Reply-To: <20200720160252.104139-1-jsnow@redhat.com>
3 seconds is too short for some tests running inside busy VMs. Build it out to
a rather generous 30 seconds to find out conclusively if there are more severe
problems in the merge/CI tests.
