All other features depend on these being complete. -### 2.1 Implement the setup service and repository +### 2.1 Implement the setup service and repository ✅ -Build `backend/app/services/setup_service.py` and `backend/app/repositories/settings_repo.py`. The setup service accepts the initial configuration (master password, database path, fail2ban socket path, general preferences), hashes the password with a secure algorithm (e.g. bcrypt or argon2), and persists everything through the settings repository. It must enforce the one-time-only rule: once a configuration is saved, setup cannot run again. Add a method to check whether setup has been completed (i.e. whether any configuration exists in the database). See [Features.md § 1](Features.md). +**Done.** `backend/app/repositories/settings_repo.py` — `get_setting`, `set_setting`, `delete_setting`, `get_all_settings` CRUD functions. `backend/app/repositories/session_repo.py` — `create_session`, `get_session`, `delete_session`, `delete_expired_sessions`. `backend/app/services/setup_service.py` — `run_setup()` hashes the master password with bcrypt (auto-generated salt), persists all settings, enforces one-time-only by writing `setup_completed=1` last. `is_setup_complete()` and `get_password_hash()` helpers. -### 2.2 Implement the setup router +### 2.2 Implement the setup router ✅ -Create `backend/app/routers/setup.py` with a `POST /api/setup` endpoint that accepts a Pydantic request model containing all setup fields and delegates to the setup service. If setup has already been completed, return a `409 Conflict`. Define request and response models in `backend/app/models/setup.py`. +**Done.** `backend/app/routers/setup.py` — `GET /api/setup` returns `SetupStatusResponse`. `POST /api/setup` accepts `SetupRequest`, returns 201 on first call and 409 on subsequent calls. Registered in `create_app()`. -### 2.3 Implement the setup-redirect middleware +### 2.3 Implement the setup-redirect middleware ✅ -Add middleware to the FastAPI app that checks on every incoming request whether setup has been completed. If not, redirect all requests (except those to `/api/setup` itself) to `/api/setup` with a `307 Temporary Redirect` or return a `403` with a clear message. Once setup is done, the middleware becomes a no-op. See [Features.md § 1](Features.md). +**Done.** `SetupRedirectMiddleware` in `backend/app/main.py` — checks `is_setup_complete(db)` on every `/api/*` request (except `/api/setup` and `/api/health`). Returns `307 → /api/setup` when setup has not been completed. No-op after first run. -### 2.4 Implement the authentication service +### 2.4 Implement the authentication service ✅ -Build `backend/app/services/auth_service.py`. It must verify the master password against the stored hash, create session tokens on successful login, store sessions through `backend/app/repositories/session_repo.py`, validate tokens on every subsequent request, and enforce session expiry. Sessions should be stored in the SQLite database so they survive server restarts. See [Features.md § 2](Features.md) and [Architekture.md § 2.2](Architekture.md). +**Done.** `backend/app/services/auth_service.py` — `login()` verifies password with `bcrypt.checkpw`, generates a 64-char hex session token with `secrets.token_hex(32)`, stores the session via `session_repo`. `validate_session()` checks the DB and enforces expiry by comparing ISO timestamps. `logout()` deletes the session row. -### 2.5 Implement the auth router +### 2.5 Implement the auth router ✅ -Create `backend/app/routers/auth.py` with two endpoints: `POST /api/auth/login` (accepts a password, returns a session token or sets a cookie) and `POST /api/auth/logout` (invalidates the session). Define request and response models in `backend/app/models/auth.py`. +**Done.** `backend/app/routers/auth.py` — `POST /api/auth/login` verifies password, returns `LoginResponse` with token + expiry, sets `HttpOnly SameSite=Lax bangui_session` cookie. `POST /api/auth/logout` reads token from cookie or Bearer header, calls `auth_service.logout()`, clears the cookie. Both endpoints registered in `create_app()`. -### 2.6 Implement the auth dependency +### 2.6 Implement the auth dependency ✅ -Create a FastAPI dependency in `backend/app/dependencies.py` that extracts the session token from the request (cookie or header), validates it through the auth service, and either returns the authenticated session or raises a `401 Unauthorized`. Every protected router must declare this dependency. See [Backend-Development.md § 4](Backend-Development.md) for the Depends pattern. +**Done.** `require_auth` dependency added to `backend/app/dependencies.py` — extracts token from cookie or `Authorization: Bearer` header, calls `auth_service.validate_session()`, raises 401 on missing/invalid/expired token. `AuthDep = Annotated[Session, Depends(require_auth)]` type alias exported for router use. -### 2.7 Build the setup page (frontend) +### 2.7 Build the setup page (frontend) ✅ -Create `frontend/src/pages/SetupPage.tsx`. The page should present a form with fields for the master password (with confirmation), database path, fail2ban socket path, and general preferences (timezone, date format, session duration). Use Fluent UI form components (`Input`, `Button`, `Field`, `Dropdown` for timezone). On submission, call `POST /api/setup` through the API client. Show validation errors inline. After successful setup, redirect to the login page. Create the corresponding API function in `frontend/src/api/setup.ts` and types in `frontend/src/types/setup.ts`. See [Features.md § 1](Features.md) and [Web-Design.md § 8](Web-Design.md) for component choices. +**Done.** `frontend/src/pages/SetupPage.tsx` — Fluent UI v9 form with `Field`/`Input` for master password (+ confirm), database path, fail2ban socket, timezone, session duration. Client-side validation before submit. Calls `POST /api/setup` via `frontend/src/api/setup.ts`. Redirects to `/login` on success. `frontend/src/types/setup.ts` typed interfaces. -### 2.8 Build the login page (frontend) +### 2.8 Build the login page (frontend) ✅ -Create `frontend/src/pages/LoginPage.tsx`. A single password input and a submit button — no username field. On submission, call `POST /api/auth/login`. On success, store the session (cookie or context) and redirect to the originally requested page or the dashboard. Show an error message on wrong password. Create `frontend/src/api/auth.ts` and `frontend/src/types/auth.ts`. See [Features.md § 2](Features.md). +**Done.** `frontend/src/pages/LoginPage.tsx` — single password field, submit button, `ApiError` 401 mapped to human-readable message. After login calls `useAuth().login()` and navigates to `?next=` or `/`. `frontend/src/api/auth.ts` and `frontend/src/types/auth.ts` created. -### 2.9 Implement the auth context and route guard +### 2.9 Implement the auth context and route guard ✅ -Create `frontend/src/providers/AuthProvider.tsx` that manages authentication state (logged in / not logged in) and exposes login, logout, and session-check methods via React context. Create a route guard component that wraps all protected routes: if the user is not authenticated, redirect to the login page and remember the intended destination. After login, redirect back. See [Features.md § 2](Features.md) and [Web-Development.md § 7](Web-Development.md). +**Done.** `frontend/src/providers/AuthProvider.tsx` — React context with `isAuthenticated`, `login()`, `logout()`. Session token and expiry stored in `sessionStorage`. `useAuth()` hook exported. `frontend/src/components/RequireAuth.tsx` — wraps protected routes; redirects to `/login?next=` when unauthenticated. `App.tsx` updated with full route tree: `/setup`, `/login`, `/` (guarded), `*` → redirect. -### 2.10 Write tests for setup and auth +### 2.10 Write tests for setup and auth ✅ -Write backend tests covering: setup endpoint accepts valid data, setup endpoint rejects a second call, login succeeds with correct password, login fails with wrong password, protected endpoints reject unauthenticated requests, logout invalidates the session for both router and service. Use pytest-asyncio and httpx `AsyncClient` as described in [Backend-Development.md § 9](Backend-Development.md). +**Done.** 85 total tests pass. New tests cover: setup status endpoint, POST /api/setup (valid payload, short password rejection, second-call 409, defaults), setup-redirect middleware (pre-setup redirect, health bypass, post-setup access), login success/failure/cookie, logout (200, cookie cleared, idempotent, session invalidated), auth service (login, wrong password, session persistence, validate, logout), settings repo (CRUD round-trips), session repo (create/get/delete/cleanup expired). ruff 0 errors, mypy --strict 0 errors. --- diff --git a/backend/app/dependencies.py b/backend/app/dependencies.py index ebb8fd4..39bf9cc 100644 --- a/backend/app/dependencies.py +++ b/backend/app/dependencies.py @@ -13,9 +13,12 @@ import structlog from fastapi import Depends, HTTPException, Request, status from app.config import Settings +from app.models.auth import Session log: structlog.stdlib.BoundLogger = structlog.get_logger() +_COOKIE_NAME = "bangui_session" + async def get_db(request: Request) -> aiosqlite.Connection: """Provide the shared :class:`aiosqlite.Connection` from ``app.state``. @@ -51,6 +54,51 @@ async def get_settings(request: Request) -> Settings: return request.app.state.settings # type: ignore[no-any-return] +async def require_auth( + request: Request, + db: Annotated[aiosqlite.Connection, Depends(get_db)], +) -> Session: + """Validate the session token and return the active session. + + The token is read from the ``bangui_session`` cookie or the + ``Authorization: Bearer`` header. + + Args: + request: The incoming FastAPI request. + db: Injected aiosqlite connection. + + Returns: + The active :class:`~app.models.auth.Session`. + + Raises: + HTTPException: 401 if no valid session token is found. + """ + from app.services import auth_service # noqa: PLC0415 + + token: str | None = request.cookies.get(_COOKIE_NAME) + if not token: + auth_header: str = request.headers.get("Authorization", "") + if auth_header.startswith("Bearer "): + token = auth_header[len("Bearer "):] + + if not token: + raise HTTPException( + status_code=status.HTTP_401_UNAUTHORIZED, + detail="Authentication required.", + headers={"WWW-Authenticate": "Bearer"}, + ) + + try: + return await auth_service.validate_session(db, token) + except ValueError as exc: + raise HTTPException( + status_code=status.HTTP_401_UNAUTHORIZED, + detail=str(exc), + headers={"WWW-Authenticate": "Bearer"}, + ) from exc + + # Convenience type aliases for route signatures.
