Type and lint pass over the openapi controllers, auth pipeline, and
oauth bearer/device-flow plumbing. Down from 36 pyright errors and 16
ruff errors to 0/0; 93 openapi unit tests pass.
Logic fixes:
- libs/oauth_bearer.py: drop private-naming on the friend-API methods
consumed by _VariantResolver (cache_get / cache_set_positive /
cache_set_negative / hard_expire / session_factory). They were always
cross-class accessors — leading underscore was misleading. Add public
registry property on BearerAuthenticator. _hard_expire row_id widened
to UUID | str (matches the StringUUID column type).
- libs/oauth_bearer.py: type validate_bearer / bearer_feature_required
with ParamSpec / PEP-695 so wrapped routes preserve their signature.
- libs/rate_limit.py: same — typed rate_limit decorator.
- services/oauth_device_flow.py: mint_oauth_token / _upsert accept
Session | scoped_session (Flask-SQLAlchemy proxy). Guard row-is-None
after upsert.
- controllers/openapi/{chat,completion,workflow}_messages.py: tuple-vs-
Mapping shape narrowing on AppGenerateService.generate return —
production returns Mapping, tests mock as (body, status). Validate
through Pydantic Response model in both shapes.
- controllers/openapi/oauth_device.py: replace flask_restx.reqparse (banned)
with Pydantic Request/Query models — DeviceCodeRequest, DevicePollRequest,
DeviceLookupQuery, DeviceMutateRequest. Two PEP-695 generic helpers
(_validate_json / _validate_query) translate ValidationError to BadRequest.
- controllers/openapi/auth/strategies.py: Protocol param-name match
(subject_type), Optional narrowing on app/tenant/account_id/subject_email.
- controllers/openapi/auth/steps.py: subject_type-is-None guard before
mounter dispatch.
- core/app/apps/workflow/generate_task_pipeline.py + models/workflow.py:
add WorkflowAppLogCreatedFrom.OPENAPI + matching match-case branch.
Fixes match-exhaustiveness and possibly-unbound created_from.
- libs/device_flow_security.py: pyright ignore on flask after_request
hook (registered by the framework, pyright sees as unused).
- services/oauth_device_flow.py: rename Exceptions to *Error suffix
(StateNotFoundError / InvalidTransitionError / UserCodeExhaustedError);
same for libs/oauth_bearer.py (InvalidBearerError / TokenExpiredError).
Update all callers across openapi controllers.
- controllers/openapi/{oauth_device,oauth_device_sso}.py +
services/oauth_device_flow.py: switch logger.error in except blocks
to logger.exception (TRY400) — keeps the traceback for ops.
- configs/feature/__init__.py: OPENAPI_KNOWN_CLIENT_IDS computed_field
needs an @property alongside for pyright to see it as a value, not a
method. Matches the existing line-451 pattern.
Plus ruff format + import-sort across the openapi tree (pure formatting).
Adds the openapi blueprint branch in load_user_from_request so that
account-branch device-flow approval routes (approve / deny /
approval-context) can authenticate via the console session cookie
under @login_required.
Splits extract_access_token into two helpers:
- extract_console_cookie_token (cookie-only) — used by openapi
approval routes that must not fall through to the Authorization
header, where dfoa_/dfoe_ bearers live (those aren't JWTs and
PassportService.verify would crash on them).
- extract_access_token retains both code paths for legacy callers.
Web and CLI consumers now hit /openapi/v1/* directly, so the dual-mount
shims can go:
- controllers/oauth_device_sso.py (legacy /v1/oauth/device/sso-* + /v1/device/sso-complete)
- controllers/service_api/oauth.py (legacy /v1/oauth/device/*, /v1/me, /v1/oauth/authorizations/self)
- controllers/console/auth/oauth_device.py (placeholder for legacy /console/api/oauth/device/{approve,deny})
- the deferred _register_legacy_console_mount() inside openapi/oauth_device.py
Imports in controllers/console/__init__.py, controllers/service_api/__init__.py,
and extensions/ext_blueprints.py pruned. Tests rewritten to openapi-only.
OPENAPI_CORS_ALLOW_ORIGINS env var defaults to empty (same-origin only).
Operators expand for third-party integrations via comma-separated list.
Allowed headers: Authorization, Content-Type, X-CSRF-Token. Methods:
GET POST PATCH DELETE OPTIONS. Max-Age 600s. supports_credentials=True
so cookie-authed approve/deny work once Phase D moves them in.
Disallowed origins receive a normal 200 OPTIONS response without the
Access-Control-Allow-Origin header — flask-cors's standard behavior;
browser blocks the cross-origin request from the disallowed origin.
Plan: docs/superpowers/plans/2026-04-26-openapi-migration.md (in difyctl repo).
New Flask blueprint at /openapi/v1/ that will host user-scoped
programmatic endpoints (device flow, identity, sessions, workspaces).
Ships only a smoke route GET /openapi/v1/_health for now; subsequent
phases lift handlers in from service_api, console, and the orphan
oauth_device_sso.py.
CORS is intentionally omitted here and configured in step A.5 once
the allowlist envvar lands.
Plan: docs/superpowers/plans/2026-04-26-openapi-migration.md (in difyctl repo).
Adds a CLI-friendly authorization flow so difyctl (and future
non-browser clients) can obtain user-scoped tokens without copy-
pasting cookies or raw API keys. Two grant paths share one device
flow surface:
1. Account branch — user signs in via the existing /signin
methods, /device page calls console-authed approve, mints a
dfoa_ token tied to (account_id, tenant).
2. External-SSO branch (EE) — /v1/oauth/device/sso-initiate signs
an SSOState envelope, hands off to Enterprise's external ACS,
receives a signed external-subject assertion, mints a dfoe_
token tied to (subject_email, subject_issuer).
API surface (all under /v1, EE-only endpoints 404 on CE):
POST /v1/oauth/device/code — RFC 8628 start
POST /v1/oauth/device/token — RFC 8628 poll
GET /v1/oauth/device/lookup — pre-validate user_code
GET /v1/oauth/device/sso-initiate — SSO branch entry
GET /v1/device/sso-complete — SSO callback sink
GET /v1/oauth/device/approval-context — /device cookie probe
POST /v1/oauth/device/approve-external — SSO approve
GET /v1/me — bearer subject lookup
DELETE /v1/oauth/authorizations/self — self-revoke
POST /console/api/oauth/device/approve — account approve
POST /console/api/oauth/device/deny — account deny
Core primitives:
- libs/oauth_bearer.py: prefix-keyed TokenKindRegistry +
BearerAuthenticator + validate_bearer decorator. Two-tier scope
(full vs apps:run) stamped from the registry, never from the DB.
- libs/jws.py: HS256 compact JWS keyed on the shared Dify
SECRET_KEY — same key-set verifies the SSOState envelope, the
external-subject assertion (minted by Enterprise), and the
approval-grant cookie.
- libs/device_flow_security.py: enterprise_only gate, approval-
grant cookie mint/verify/consume (Path=/v1/oauth/device,
HttpOnly, SameSite=Lax, Secure follows is_secure()), anti-
framing headers.
- libs/rate_limit.py: typed RateLimit / RateLimitScope dispatch
with composite-key buckets; both decorator + imperative form.
- services/oauth_device_flow.py: Redis state machine (PENDING ->
APPROVED|DENIED with atomic consume-on-poll), token mint via
partial unique index uq_oauth_active_per_device (rotates in
place), env-driven TTL policy.
Storage: oauth_access_tokens table with partial unique index on
(subject_email, subject_issuer, client_id, device_label) WHERE
revoked_at IS NULL. account_id NULL distinguishes external-SSO
rows. Hard-expire is CAS UPDATE (revoked_at + nullify token_hash)
so audit events keep their token_id. Retention pruner DELETEs
revoked + zombie-expired rows past OAUTH_ACCESS_TOKEN_RETENTION_DAYS.
Frontend: /device page with code-entry, chooser (account vs SSO),
authorize-account, authorize-sso views. SSO branch detaches from
the URL user_code and reads everything from the cookie via
/approval-context. Anti-framing headers on all responses.
Wiring: ENABLE_OAUTH_BEARER feature flag; ext_oauth_bearer binds
the authenticator at startup; clean_oauth_access_tokens_task
scheduled in ext_celery.
