chiuinggum opened a new pull request, #57199:
URL: https://github.com/apache/airflow/pull/57199
# Why
- Align FAB provider with Airflow 3’s FastAPI-first direction and reduce
remaining Connexion/Flask surface. This PR is a small step for issue #56730 by
migrating a single endpoint first.
# How
- New FastAPI endpoint: implements `POST /auth/fab/v1/roles` using a router
registered by `FabAuthManager.get_fastapi_app()`. Path and success status
remain compatible (200 OK). The login FastAPI module serves as structural
precedent.
- Data models: added Pydantic models in `api_fastapi/datamodels/roles.py`
(`RoleIn`, `RoleOut`, etc.). The JSON field `actions` is preserved via aliases
while internal naming uses “permissions,” mirroring the Connexion schema.
- Service layer: `api_fastapi/services/roles.py#create_role` reproduces the
legacy flow:
1. validate role name
2. conflict if role exists (409)
3. validate action/resource pairs (400 on missing)
4. `bulk_sync_roles`
5. re-fetch or 500 on unexpected failure
- Authorization parity: introduced a FastAPI dependency that mirrors
`requires_access_custom_view("POST", RESOURCE_ROLE)`; unauthorized → 401,
forbidden → 403 (same semantics as FAB’s Connexion layer)
- OpenAPI docs: response map includes 400/401/403/409 and now 500 for the
rare “created-but-not-found” case, consistent with the new service behavior.
(FastAPI auto-generates the schema from code.)
