Add a new pulp_content_guard backend configuration option holding the pulp_href of a content guard (typically a composite guard combining a few feature guards). When set, the guard is assigned to every distribution copr creates in Pulp.

Also add the copr-pulp-set-content-guard script for (re)setting the content guard on all distributions of an existing /.

📝 Walkthrough

Walkthrough

The backend adds an optional pulp_content_guard setting. Pulp distribution creation and updates accept the guard. A new command assigns a guard to all distributions in a project. Tests cover payload behavior.

Changes

Pulp content guard support

Layer / File(s) Summary
Distribution guard configuration and API flow
backend/conf/copr-be.conf.example, backend/copr_backend/helpers.py, backend/copr_backend/pulp.py, backend/copr_backend/storage.py, backend/tests/test_pulp.py
The backend reads pulp_content_guard and passes it to Pulp distribution creation. Pulp create and update requests include content_guard when provided. Tests cover both configured and absent guards.
Bulk content guard assignment
backend/run/copr-pulp-set-content-guard
The new command accepts a project and optional guard, resolves the guard from configuration when needed, updates matching distributions, and waits for completion.

Priority: ⬇️ Low

Estimated code review effort: 3 (Moderate) | ~20 minutes

Merge Risk: 🟡 Moderate · up to 7d529

The new command can either fail to start on supported Python environments or report success after updating only the first page of project distributions. These issues should be resolved before relying on it for bulk content-guard assignment.
