[JIRA] (OVIRT-1821) jenkins 'check-patch.sh' does not always generate differences.html in downstream repos

jenkins 'check-patch.sh' does not always generate differences.html in downstream repos -------------------------------------------------------------------------------------- Key: OVIRT-1821 URL: https://ovirt-jira.atlassian.net/browse/OVIRT-1821 Project: oVirt - virtualization made easy Issue Type: Bug Reporter: Barak Korren Assignee: infra Labels: standard-ci The 'check-patch.sh' script in the 'jenkins' repo knows how to generate a 'differences.html' file when job YAML changes. The 'jenkins' repo is designed to be used as an upstream source repo for other repos, and it is designed that 'check-patch.sh' will be usable on those DS repos. When YAML changes from the 'jenkins' repo make it into the DS repos via a patch to the 'upstream-sources.yaml' file in the DS repo, and 'check-patch.sh' runs on that repo, 'differences.html' is not being generated, because the change to 'upstream-sources.yaml' does not look like a job YAML change. We need to change 'check-patch.sh' so that when running in a DS repo, it knows how to look and diagnose changes coming from the upstream repo.
