What do you mean by "pipline job" and "commit job" here? For a pull request, it will show all jobs configured with trigger "pull request open/update", and the commit these jobs fired off is the current merge commit (target branch and source branch) of the pull request.

commit build job is the one inline with a commit pipeline build job -> I meant PR build job, is the one displayed on the right in a PR

I think the issue there was the conflicting triggers mentioned in issue #863

I see. Commit job is different from PR job. When you push a commit to source branch of a pull request, the commit job runs against head commit of the source branch if you have a trigger to run job upon branch update, and PR job runs against merged commit of source branch and target branch if you have a trigger to run job upon pull request open or update.

If you observe odd behavior, please try to reproduce it and let me know the steps.

I've since figured out the difference, thanks
