From 1cdf413ac6f993dc2074741be4627acdc3f10304 Mon Sep 17 00:00:00 2001 From: Dan Smith Date: Mon, 23 May 2022 13:56:13 -0700 Subject: [PATCH] Do not barf stack trace if stats DB is missing This can happen if devstack fails to run, but we still run the post tasks. Also could happen if some sort of hybrid job configuration does not run all of devstack but we still end up running post jobs. Just warn to stderr and assume no DB info.
