[JIRA] (OVIRT-2446) Github push trigger will fail if was trigger by a tag push

Roy Golan created OVIRT-2446: -------------------------------- Summary: Github push trigger will fail if was trigger by a tag push Key: OVIRT-2446 URL: https://ovirt-jira.atlassian.net/browse/OVIRT-2446 Project: oVirt - virtualization made easy Issue Type: By-EMAIL Reporter: Roy Golan Assignee: infra When pushing a tag to a GH it triggers the jenkins webhook. In the invoked job, it will try to fech a new head with that tag, but that will fail since the repo doesn't have a head since it is started as git init. A breakdown from https://jenkins.ovirt.org/job/oVirt_ovirt-openshift-extensions_standard-o... - git init a repo *14:57:15* > git init /home/jenkins/workspace/oVirt_ovirt-openshift-extensions_standard-on-ghpush/ovirt-openshift-extensions # timeout=10 - git fetch tags (maybe the problem is here as it doesn't reffer to refs/tags) *15:35:07* [check-merged.el7.x86_64] > git fetch --tags --progress https://gerrit.ovirt.org/jenkins +refs/heads/*:refs/remotes/origin/* - fetch upstream changes, which is here a tag v0.3.2, so it uses 'refs/tags/v0.3.2' *14:57:18* > git fetch --tags --progress https://github.com/oVirt/ovirt-openshift-extensions +refs/tags/v0.3.2:myhead This fails with *14:57:19* stderr: error: cannot update ref 'refs/heads/myhead': trying to write non-commit object 3c7b5a5d243d1f3bcecbe7b527726b06113d0ec5 to branch 'refs/heads/myhead' While in regular merge with a tag on it uses 'refs/heads/master': *15:35:10* [check-merged.el7.x86_64] > git fetch --tags --progress https://gerrit.ovirt.org/jenkins +refs/heads/master:myhead Since refs/tags/v0.3.2 doesn't exist locally it can't reference it. Since refs/heads/master exists locally it can create the alias 'myhead' to it. I would like to have the option to push a tag and trigger a build but this is not working atm without a commit attached to it. -- This message was sent by Atlassian Jira (v1001.0.0-SNAPSHOT#100090)
