`import-url --file=something.yaml ...` doesn't save stage anywhere

[Suor]

The underlying issue is PipelineFile.dump() having unsafe design and breaking polymorphism. Here the suffix of the --file determines what class will be used as Dvcfile and while SingleStageFile.dump() indeed dumps the stage, PipelineFile.dump() does not by default.

This issue caused #3907 and was explained there in more detail. It may cause other undiscovered and future issues.

@Suor, import stages are not supported for dvc.yaml.

Nothing stops me from trying though, dvc will act surprisingly.

And I spend 10 minutes to find this, there are probably more. Until PipelineFile.dump() is fixed this will continue.

So why there are two kinds of dvcfile ? Compatible with the older version?

@karajan1001 Sorry for the delay. Correct, we are using dvc.yaml for pipelines and *.dvc for dvc add/import/import-url.

@Suor @efiop Is this still an issue? For now, I'm lowering the priority to p2.

Closing as stale.
