Re: [libvirt] [PATCH 10/10] Don't ignore allocation failure in virCommandAddEnvPassCommon

From: "Daniel P. Berrange" <berrange(a)redhat.com&gt; The virCommandAddEnvPassCommon method ignored the failure to pre-allocate the env variable array with VIR_RESIZE_N. While this is harmless, it confuses the test harness which is trying to validate OOM handling of every individual allocation call. Signed-off-by: Daniel P.
