The 2 pipelines you see are
- readdocs pipeline
- merge-pipeline - auto starts - does the pre stage and pauses.

Its not a replacement for merge train.[merge train is a way to do the merge when the MR is tested and ready for merge]

However you can use this as a replacement for starting a new pipeline from the web interface https://gitlab.com/petsc/petsc/-/pipelines/new
[i.e instead of starting a web interface pipeline - you just go to the MR page - 'pipeline tab' and hit continue]

Or you can ignore this and continue to use the web interface.

You shouldn't have to cancel the automatic MR pipeline. They should just stay paused.

And I don't remember getting e-mails from these stalled MR pipelines. Perhaps you got them because of pre-stage failures?

However if you have errors in pre stage tests - you might as well check and fix them.

The one thats causing most trouble is readdocs pipeline. Its probably best to disable it until its issues are resolved.
