From ef563c5a1e1a638a99dc615a34324d068993c106 Mon Sep 17 00:00:00 2001 From: Ed Santiago Date: Wed, 15 Jun 2022 13:10:32 -0600 Subject: logformatter: link to logs using Cirrus API One day we may use AWS for part of CI. Do you want to maintain two separate code paths in this script for linking to artifacts in multiple cloud providers? Can you say no? I knew you could. Cirrus already knows the location of the artifacts and provides a transparent mechanism for accessing them. Use it. This PR exposed a nasty bug in our environment-variable handling: envariables passed through to the containerized environment were being double-space-escaped, so "FOO=a b" ended up as "FOO=a\ b" (with a backslash), with one consequence being invalid URLs. The solution is simple: run 'podman -e FOO', not '-e FOO=value'. Finally, reinstate the environment-variable dump (in comments). I had removed this in a moment of panic over leaking secrets, but no, that doesn't happen. Exclude scary-sounding vars anyway.
