The ServiceLauncher and ProcessLauncher in oslo.service will, by default, log config options at DEBUG level at the start of a service, which is what would happen when starting nova-api using eventlet. Running nova-api under wsgi has been supported since Pike, but the wsgi app code doesn't log the debug options like oslo.service would, so this adds that back in. The placement-api wsgi app code would log the options but based on whether or not debug logging is enabled, which is different from how it works in oslo.service, so the config option that is checked is changed in this patch, and a release note is added for that subtle behavior change. Closes-Bug: #1732000 Change-Id: I680fd9761a049cac619b7793fa5c60e6daf4fa47
