How to check if repository mirror is up to date in Gitlab?

Question

I am trying to use repository mirroring to streamline my workflow. I have a repository that uses pull mirroring from the upstream. I am trying to trigger mirror update via api

My questions:

• Can I find out that the mirror update I triggered if finished?
• Alternatively, can I find out if the mirror (or a particular branch on a mirror) is up-to-date with the upstream?

To give you more context, I want to:

• refresh the mirror
• create a branch on the mirror
• create a merge request to the upstream

I refresh the mirror to ensure that the merge request can be merged without conflicts. My pipeline is the only source of merge requests to the upstream. I am afraid of race condition between refresh mirror request and create branch request.

Answer 1

There are two fields ton the get single project endpoint GET /projects/:id

• import_status (with "finished" as a marker of success)
• import_error (with null as a marker of success)

I wasn't able to find out the timestamp of last mirror update though.
