Pulp

Here's some background information.

One can create an importer for a file repository with one of three download policies: immediate, on_demand and background. For more information, see the documentation on pulp.app.models.Importer. Unfortunately, the on_demand and background download policies are implemented as no-ops. This means that:

• If the desired content has already been downloaded and cached on disk, syncs will succeed.
• If the desired content has not been downloaded and cached on disk, syncs will fail.

As a user, my expectation is that if a download policy is unsupported, then it should be impossible to create an importer with that download policy. It's highly surprising that one can create a file importer with an unsupported download policy.
