RPM Support

Let's say I execute the following commands:

pulp-admin rpm repo create \
    --repo-id ichi \
    --feed 'https://repos.fedorapeople.org/pulp/pulp/fixtures/rpm/' \
    --download-policy on_demand
pulp-admin -vv rpm repo sync run --repo-id ichi
pulp-admin -vv repo download --repo-id ichi

Importantly, the repository has an on_demand download policy. As a result, the repo sync run command doesn't download any content units from the remote repository onto disk. The third command forces content units to be downloaded onto disk. (Adding --verify-all has no effect.)

For more information on this feature, see:

• http://docs.pulpproject.org/dev-guide/integration/rest-api/repo/sync.html?highlight=verify_all_units#download-a-repository
• http://docs.pulpproject.org/user-guide/deferred-download.html?highlight=verify_all_units#re-using-files-on-disk-when-db-is-lost

Well, that's what's supposed to happen. In reality, Pulp never downloads any content units onto disk. This especially apparent if one resets Pulp directly before executing the script above: no /var/lib/pulp/content directory is created.

The system logs show no indication that anything has gone wrong:

The best clue I have as to what's wrong are the task reports. Here's an example of what pulp-admin writes to console during the execution of the third script command, above:
