Please use git shallow clone as jobs default -------------------------------------------- Key: OVIRT-1173 URL: https://ovirt-jira.atlassian.net/browse/OVIRT-1173 Project: oVirt - virtualization made easy Issue Type: By-EMAIL Reporter: rgolan Assignee: infra Labels: standard-ci Most if not all the git clone of the jobs don't need history at all. For ovirt-engine I see it downloading *11Mb* using --depth 1 vs. *157Mb* for regular clone. R
