Pulp

Ticket moved to GitHub: "pulp/pulpcore/1896":https://github.com/pulp/pulpcore/issues/1896

Background¶

Pulp architecturally cannot have a task that waits on another task, otherwise on systems where only 1 pulp worker is running Pulp will deadlock. Pulp workers only work on one task at a time, so here is the deadlock example:

1. Task foo starts running
2. Task foo dispatches task bar
3. Task bar never starts because Task foo never finishes and there is only one worker
4. despair

Solution¶

Document a new section named "tasks waiting on tasks" in the plugin writer's guide Tasks section here. It should document this.
