GitLab pipeline API change: detached pipeline refs changed - Marge fails to detect pipeline

[veeg]

Due to recent GitLab API Change, the refs slug received from list pipelines returns a ref changed to format refs/merge-requests/[MERGE_REQUEST_NUMBER]/head, instead of [BRANCH_NAME].

This is only applicable when the pipeline is ran on merge_requests, e.g., detached.

The following call needs to be augmented with a refs argument:

marge-bot/marge/job.py

Lines 138 to 142 in 183be28

	pipelines = Pipeline.pipelines_by_branch(
	merge_request.source_project_id,
	merge_request.source_branch,
	self._api,
	)

[veeg]

This API change has renderes Margebot useless for our deployment.

Does anyone have a suggestion on how this scenario should be handled, and I can have a stab at implementing it.

We are stymied by this too. One thought could be to get all of the pipelines associated with the project_id, by adding an all_pipelines() method to Pipeline, requiring the iterator in get_mr_ci_status() looking for the matching sha to deal with the longer list.
