The map component itself tracks no hover state. This task adds pointer-event handlers to each country `` element, tracks the hovered country in local state together with the last known mouse coordinates, and renders a positionned HTML tooltip `
` on top of the SVG. +**Violated rule:** Refactoring.md §2.2 — Services must not perform direct `aiosqlite` calls; go through a repository. -**Implementation steps:** +**Files affected:** +- `backend/app/services/ban_service.py` — lines 247, 398, 568, 646: four separate `aiosqlite.connect(f"file:{db_path}?mode=ro", uri=True)` blocks that execute raw SQL against the fail2ban SQLite database. +- `backend/app/services/history_service.py` — lines 118, 208: two more direct `aiosqlite.connect()` blocks against the fail2ban database. -1. **Extend `WorldMapProps` and `GeoLayerProps`** in `WorldMap.tsx`: - - Add `countryNames?: Record` to `WorldMapProps` (optional — falls back to the ISO alpha-2 code when absent). - - Thread it through `GeoLayer` the same way the threshold props are already threaded. +**What to do:** -2. **Add hover state to `GeoLayer`** — declare: - ```ts - const [tooltip, setTooltip] = useState<{ - cc: string; - count: number; - name: string; - x: number; - y: number; - } | null>(null); - ``` - On each country `` element add: - - `onMouseEnter` — set `tooltip` with the country code, count, display name (from `countryNames`, falling back to the alpha-2 code), and mouse page coordinates (`e.clientX`, `e.clientY`). - - `onMouseMove` — update only the `x`/`y` in the existing tooltip (keep name/count stable). - - `onMouseLeave` — set `tooltip` to `null`. - - Skip setting the tooltip for countries where `cc === null` (no ISO mapping available) but keep `onMouseLeave` so re-entering after leaving from an unmapped border still clears the state. - -3. **Render the tooltip inside `GeoLayer`** — because `GeoLayer` is rendered inside `ComposableMap` which is inside `mapWrapper`, the tooltip div cannot be positioned relative to the map wrapper from here (the SVG clip/transform would offset it). Instead, use a React **portal** (`ReactDOM.createPortal`) to mount the tooltip directly on `document.body` so it sits in the root stacking context and can be positioned with `position: fixed` using the raw `clientX`/`clientY` coordinates. - - Tooltip structure (styled with a new `makeStyles` class `tooltip` in `WorldMap.tsx`): - ```tsx - {tooltip && - createPortal( -
- {tooltip.name} - - {tooltip.count.toLocaleString()} ban{tooltip.count !== 1 ? "s" : ""} - -
, - document.body, - )} - ``` - -4. **Tooltip styles** — add three new classes to the `makeStyles` call in `WorldMap.tsx`: - ```ts - tooltip: { - position: "fixed", - zIndex: 9999, - pointerEvents: "none", - backgroundColor: tokens.colorNeutralBackground1, - border: `1px solid ${tokens.colorNeutralStroke2}`, - borderRadius: tokens.borderRadiusSmall, - padding: `${tokens.spacingVerticalXS} ${tokens.spacingHorizontalS}`, - display: "flex", - flexDirection: "column", - gap: tokens.spacingVerticalXXS, - boxShadow: tokens.shadow4, - }, - tooltipCountry: { - fontSize: tokens.fontSizeBase200, - fontWeight: tokens.fontWeightSemibold, - color: tokens.colorNeutralForeground1, - }, - tooltipCount: { - fontSize: tokens.fontSizeBase200, - color: tokens.colorNeutralForeground2, - }, - ``` - -5. **Pass `countryNames` from `MapPage`** — in `MapPage.tsx`, add the `countryNames` prop to the existing `` JSX: - ```tsx - - ``` - -6. **Countries with zero bans** — the tooltip should still appear when the user hovers over a country with `0` bans (showing the name and "0 bans"), so users know the country is tracked but has no bans. Do not suppress the tooltip for zero-count countries. - -**Acceptance criteria:** -- Moving the pointer over any mapped country on the Map page shows a floating tooltip within 0 ms (synchronous state update) containing the country's full display name (e.g. `Germany`) on the first line and the ban count (e.g. `42 bans` or `0 bans`) on the second line. -- Moving the pointer off a country hides the tooltip immediately. -- The tooltip follows the pointer as it moves within a country's borders. -- Clicking a country still selects/deselects it exactly as before; the tooltip does not interfere with the click handler. -- The tooltip is not interactive (`pointerEvents: none`) and does not steal focus from the map. -- `tsc --noEmit` produces no new errors. - -**Status:** ✅ Completed (2026-03-19) +1. Create `backend/app/repositories/fail2ban_db_repo.py`. +2. Move all SQL that touches the fail2ban database into clearly named async functions in that module. Each function must accept the fail2ban database path (`db_path: str`) as a parameter (connection management stays inside the repository function, since the fail2ban database is an external, read-only resource not managed by BanGUI's own connection pool). + - `get_currently_banned(db_path, jail_filter, since) -> list[BanRecord]` + - `get_ban_counts_by_bucket(db_path, ...) -> list[int]` + - `check_db_nonempty(db_path) -> bool` + - `get_history_for_ip(db_path, ip) -> list[HistoryRecord]` + - `get_history_page(db_path, ...) -> tuple[list[HistoryRecord], int]` + — Adjust signatures as needed to cover all query sites. +3. Replace the inline `aiosqlite.connect` blocks in `ban_service.py` and `history_service.py` with calls to the new repository functions. +4. Add the new repository to `backend/tests/test_repositories/` with unit tests that mock the SQLite file. --- -## Feature: Global Unique BanGUI Version +#### TASK B-2 — Remove direct SQL query from `routers/geo.py` -> **2026-03-17** -> The BanGUI application version is currently scattered across three independent files that are not kept in sync: -> - `Docker/VERSION` — `v0.9.8` (release artifact, written by the release script) -> - `frontend/package.json` — `0.9.8` -> - `backend/pyproject.toml` — `0.9.4` ← **out of sync** -> -> Additionally the BanGUI version is only shown in the sidebar footer (`MainLayout.tsx`). Neither the Dashboard nor the Configuration → Server view exposes the BanGUI application version, only the fail2ban daemon version. -> -> Goal: one authoritative version string, propagated automatically to all layers, and displayed consistently on both the Dashboard and the Configuration → Server page. +**Status:** Completed ✅ + +**Violated rule:** Refactoring.md §2.1 — Routers must contain zero business logic; no SQL or repository imports. + +**Files affected:** +- `backend/app/routers/geo.py` — lines 157–165: the `re_resolve_geo` handler runs `db.execute("SELECT ip FROM geo_cache WHERE country_code IS NULL")` directly. + +**What to do:** + +1. Add a function `get_unresolved_ips(db: aiosqlite.Connection) -> list[str]` to the appropriate repository (`geo_cache_repo.py` — create it if it does not yet exist, or add it to `settings_repo.py` if the table belongs there). +2. In the router handler, replace the inline SQL block with a single call to the new repository function via `geo_service` (preferred) or directly if the service layer already handles this path. +3. The final handler body must contain no `db.execute` calls. --- -### Task GV-1 — Establish a single source of truth for the BanGUI version +#### TASK B-3 — Remove repository import from `routers/blocklist.py` -**Scope:** `Docker/VERSION`, `backend/pyproject.toml`, `frontend/package.json`, `backend/app/__init__.py` +**Violated rule:** Refactoring.md §2.1 — Routers must not import from repositories; all data access must go through services. -`Docker/VERSION` is already the file written by the release script (`Docker/release.sh`) and is therefore the natural single source of truth. +**Files affected:** +- `backend/app/routers/blocklist.py` — line 45: `from app.repositories import import_log_repo`; the `get_import_log` handler (around line 220) calls `import_log_repo.list_logs()` directly. -1. Sync the two package manifests to the current release version: - - Set `version` in `backend/pyproject.toml` to `0.9.8` (strip the leading `v` that `Docker/VERSION` contains). - - `frontend/package.json` is already `0.9.8` — no change needed. -2. Make the backend read its version **directly from `Docker/VERSION`** at import time instead of from `pyproject.toml`, so a future release-script bump of `Docker/VERSION` is sufficient. Update `_read_pyproject_version()` in `backend/app/__init__.py`: - - Add a new helper `_read_docker_version() -> str` that resolves `Docker/VERSION` relative to the repository root (two `parents` above `backend/app/`), strips the leading `v` and whitespace, and returns the bare semver string. - - Change `_read_version()` to try `_read_docker_version()` first, then fall back to `_read_pyproject_version()`, then `importlib.metadata`. -3. Make the frontend read its version from `Docker/VERSION` at build time. In `frontend/vite.config.ts`, replace the `pkg.version` import with a `fs.readFileSync('../Docker/VERSION', 'utf-8').trim().replace(/^v/, '')` call so both the dev server and production build always reflect the file. - - Update `declare const __APP_VERSION__: string;` in `frontend/src/vite-env.d.ts` if the type declaration needs adjustment (it should not). +**What to do:** -**Acceptance criteria:** -- `backend/app/__version__` equals the content of `Docker/VERSION` (without `v` prefix) at runtime. -- `frontend` build constant `__APP_VERSION__` equals the same value. -- Bumping only `Docker/VERSION` (e.g. `v0.9.9`) causes both layers to pick up the new version without touching any other file. -- All existing tests pass (`pytest backend/`). - -**Status:** ✅ Completed (2026-03-19) +1. Add a `list_import_logs(db, source_id, page, page_size) -> tuple[list[ImportRunResult], int]` method to `blocklist_service.py` (it can be a thin wrapper that calls `import_log_repo.list_logs` internally). +2. In the router, replace the direct `import_log_repo.list_logs(...)` call with `await blocklist_service.list_import_logs(...)`. +3. Remove the `import_log_repo` import from the router. --- -### Task GV-2 — Expose the BanGUI version through the API +#### TASK B-4 — Move `conffile_parser.py` from `services/` to `utils/` -**Scope:** `backend/app/models/server.py`, `backend/app/models/config.py`, `backend/app/routers/dashboard.py`, `backend/app/routers/config.py` +**Violated rule:** Refactoring.md §2.2 and Architecture §2.1 — `services/` is for business logic. `conffile_parser.py` is a pure, stateless parsing library with no framework dependencies (no FastAPI, no aiosqlite). It belongs in `utils/`. -Add a `bangui_version` field to every API response that already carries the fail2ban daemon `version`, so the frontend can display the BanGUI application version next to it. +**Files affected:** +- `backend/app/services/conffile_parser.py` — all callers that import from `app.services.conffile_parser`. -1. **`backend/app/models/server.py`** — Add to `ServerStatusResponse`: +**What to do:** + +1. Move the file: `backend/app/services/conffile_parser.py` → `backend/app/utils/conffile_parser.py`. +2. Update every import in the codebase from `from app.services.conffile_parser import ...` to `from app.utils.conffile_parser import ...`. +3.

Replace every `db.execute` / `db.executemany` call in `geo_service.py` with calls to the new repository. +3. Add tests in `backend/tests/test_repositories/test_geo_cache_repo.py`. + +--- + +#### TASK B-6 — Remove direct SQL from `tasks/geo_re_resolve.py` + +**Violated rule:** Refactoring.md §2.5 — Tasks must not use repositories directly; they must call a service method. + +**Files affected:** +- `backend/app/tasks/geo_re_resolve.py` — line 53: `async with db.execute("SELECT ip FROM geo_cache WHERE country_code IS NULL")`. + +**What to do:** + +After completing TASK B-5, a `geo_service` method (or via `geo_cache_repo` through `geo_service`) that returns unresolved IPs will exist. + +1. Replace the inline SQL block in `_run_re_resolve` with a call to that service method (e.g., `unresolved = await geo_service.get_unresolved_ips(db)`). +2. The task function must contain no `db.execute` calls of its own. + +--- + +#### TASK B-7 — Replace `Any` type annotations in `ban_service.py` + +**Violated rule:** Backend-Development.md §1 — Never use `Any`; all functions must have explicit type annotations. + +**Files affected:** +- `backend/app/services/ban_service.py` — lines 192, 271, 346, 434, 455: uses of `Any` for `geo_enricher` parameter and `geo_map` dict value type. + +**What to do:** + +1. Define a precise callable type alias for the geo enricher, e.g.: ```python - bangui_version: str = Field(..., description="BanGUI application version.") + from collections.abc import Awaitable, Callable + GeoEnricher: TypeAlias = Callable[[str], Awaitable[GeoInfo | None]] ``` -2. **`backend/app/models/config.py`** — Add to `ServiceStatusResponse`: - ```python - bangui_version: str = Field(..., description="BanGUI application version.") - ``` -3. **`backend/app/routers/dashboard.py`** — In `get_server_status`, import `__version__` from `app` and populate the new field: - ```python - return ServerStatusResponse(status=cached, bangui_version=__version__) - ``` -4. **`backend/app/routers/config.py`** — Do the same for the `GET /api/config/service-status` endpoint. - -**Do not** change the existing `version` field (fail2ban daemon version) — keep it exactly as-is so nothing downstream breaks. - -**Acceptance criteria:** -- `GET /api/dashboard/status` response JSON contains `"bangui_version": "0.9.8"`. -- `GET /api/config/service-status` response JSON contains `"bangui_version": "0.9.8"`. -- All existing backend tests pass. -- Add one test per endpoint asserting that `bangui_version` matches `app.__version__`. - -**Status:** ✅ Completed (2026-03-19) +2. Replace `geo_enricher: Any | None` with `geo_enricher: GeoEnricher | None` (both occurrences). +3. Replace `geo_map: dict[str, Any]` with `geo_map: dict[str, GeoInfo]` (both occurrences). +4.

Add a second badge directly adjacent to it that reads `BanGUI v{status.bangui_version}` with the tooltip `"BanGUI version"`. Match the existing badge style. - -3. **Configuration → Server — `ServerHealthSection.tsx`** - The health section already renders a `Version` row with the fail2ban version. Add a new row below it labelled `BanGUI` (or `BanGUI Version`) that renders `{status.bangui_version}`. Apply the same `statLabel` / `statValue` CSS classes used by the adjacent rows. - -4. **Remove the duplicate from the sidebar** — Once the version is visible on the relevant pages, the sidebar footer in `frontend/src/layouts/MainLayout.tsx` can drop `v{__APP_VERSION__}` to avoid showing the version in three places. Replace it with the plain product name `BanGUI` — **only do this if the design document (`Docs/Web-Design.md`) does not mandate showing the version there**; otherwise leave it and note the decision in a comment. - -**Acceptance criteria:** -- Dashboard status bar shows `BanGUI v0.9.8` with an appropriate tooltip. -- Configuration → Server health section shows a `BanGUI` version row reading `0.9.8`. -- No TypeScript compile errors (`tsc --noEmit`). -- Both values originate from the same API field (`bangui_version`) and therefore always match the backend version. - -**Status:** ✅ Completed (2026-03-19) +Remove or rewrite the docstring snippet so it does not contain a bare `print()` call. If the example is kept, annotate it clearly as a documentation-only code block that should not be copied into production code, or replace with a comment like `# info.country_code == "DE"`. --- + +#### TASK B-9 — Remove direct SQL from `main.py` lifespan into `geo_service` + +**Violated rule:** Refactoring.md §2 — Application startup code must not execute raw SQL; data-access logic belongs in a repository (or, when count semantics belong to a domain concern, a service method). + +**Files affected:** +- `backend/app/main.py` — lines 164–168: the lifespan handler runs `db.execute("SELECT COUNT(*) FROM geo_cache WHERE country_code IS NULL")` directly to log a startup warning about unresolved geo entries. + +**What to do:** + +1. After TASK B-5 is complete, `geo_cache_repo` will expose a `get_stats(db) -> dict[str, int]` function (or a dedicated `count_unresolved(db) -> int`). Use that. +2.

Define a shared `GeoEnricher` type alias (e.g., in `app/services/geo_service.py` or a new `app/models/geo.py`) similar to TASK B-7. -2. Update `history_service.py` to use `GeoEnricher | None` for the `geo_enricher` parameter. -3. Replace `list[Any]` for SQL parameters with a more precise type (e.g., `list[object]` or a custom `SqlParam` alias). -4.

Replace `Any` with those aliases in `_ok`, `_safe_get`, and other helper functions. -3. Ensure the public API functions (`get_settings`, etc.) have explicit return types and avoid propagating `Any` to callers. -4.

Invoke this hook in the parent page (`JailDetailPage`) and pass `bannedIps`, `loading`, `error`, `onUnban`, and pagination props down to `BannedIpsSection`. -3. Remove all `api/` imports from `BannedIpsSection.tsx`; the component receives everything through props. -4.

Identify or create the appropriate hook in `frontend/src/hooks/`. Group related concerns — for example, a single `useFiltersConfig` hook can cover fetch, update, and create actions for filters. -2. Move all `useEffect` + API call patterns from the component into the hook. The hook must return `{ data, loading, error, refetch, ...actions }`. -3. The component must receive data and action callbacks exclusively through props or a hook called in its closest page ancestor. -4.

The `useSetup` hook created for TASK F-1 exposes setup-status fetching. Reuse it here, or extract the status-only slice into a `useSetupStatus()` hook that `SetupGuard` and `SetupPage` can both consume. -2. Replace the inline `useEffect` + `getSetupStatus` pattern in `SetupGuard` with a call to the hook. -3. Remove the direct `../api/setup` import from `SetupGuard.tsx`. -4.

The `fetchMapColorThresholds` / `updateMapColorThresholds` concern overlaps with TASK F-3 (`useMapColorThresholds` hook). Extend that hook or create a dedicated `useMapColorThresholdsConfig` hook that also exposes an `update(payload)` action. -2. Add `reload()` and `restart()` actions to a suitable config hook (e.g., a `useServerActions` hook or extend `useServerSettings` in `src/hooks/useConfig.ts`). -3. Replace all direct `reloadConfig()`, `restartFail2Ban()`, `fetchMapColorThresholds()`, and `updateMapColorThresholds()` calls in `ServerTab` with the hook-provided actions. -4. Remove all `../../api/config` imports for these four functions from `ServerTab.tsx`. - -**Dependency:** Coordinate with TASK F-3 to avoid creating duplicate `useMapColorThresholds` hook logic. - ---- - -#### TASK F-9 — Move `TimezoneProvider` API call into a hook - -**Status:** Completed ✅ - -**Violated rule:** Refactoring.md §3.2 — A component (including a provider component) must not contain a `useEffect` that calls an API function directly; API calls belong in `src/hooks/`. - -**Files affected:** -- `frontend/src/providers/TimezoneProvider.tsx` — line 20: imports `fetchTimezone` from `../api/setup`; lines 57–62: calls it directly inside a `useCallback` that is invoked from `useEffect`. - -**What to do:** - -1. Create `frontend/src/hooks/useTimezoneData.ts` (or add to an existing setup-related hook) that fetches the timezone and returns `{ timezone, loading, error }`. -2. Call this hook inside `TimezoneProvider` and drive the context value from the hook's `timezone` output — removing the inline `fetchTimezone()` call. -3. Remove the direct `../api/setup` import from `TimezoneProvider.tsx`. -4.

A single unhandled exception in any component will crash the entire application with a white screen. -**Allowed content:** request parsing, response serialisation, dependency injection via `Depends()`, delegation to a service, HTTP error mapping. -**Forbidden content:** SQL queries, business logic, direct use of `fail2ban_client`, any logic that would also make sense in a unit test without an HTTP request. - -Checklist: -- [ ] Every handler calls exactly one service method per logical operation. -- [ ] No `if`/`elif` chains that implement business rules — move these to the service. -- [ ] No raw SQL or repository imports. -- [ ] All response models are Pydantic schemas from `app/models/`. -- [ ] HTTP status codes are consistent with API conventions (200 OK, 201 Created, 204 No Content, 400/422 for client errors, 404 for missing resources, 500 only for unexpected failures). - -### 2.2 Services (`app/services/`) - -**Allowed content:** business rules, coordination between repositories and external clients, validation that goes beyond Pydantic, fail2ban command orchestration. -**Forbidden content:** raw SQL, direct aiosqlite calls, FastAPI `HTTPException` (raise domain exceptions instead and let the router or exception handler convert them). - -Checklist: -- [ ] Service classes / functions accept plain Python types or domain models — not `Request` or `Response` objects. -- [ ] No direct `aiosqlite` usage — go through a repository. -- [ ] No `HTTPException` — raise a custom domain exception or a plain `ValueError`/`RuntimeError` with a clear message. -- [ ] No circular imports between services — if two services need each other's logic, extract the shared logic to a utility or a third service. - -### 2.3 Repositories (`app/repositories/`) - -**Allowed content:** SQL queries, result mapping to domain models, transaction management. -**Forbidden content:** business logic, fail2ban calls, HTTP concerns, logging beyond debug-level traces. - -Checklist: -- [ ] Every public method accepts a `db: aiosqlite.Connection` parameter — sessions are not managed internally. -- [ ] Methods return typed domain models or plain Python primitives, never raw `aiosqlite.Row` objects exposed to callers. -- [ ] No business rules (e.g., no "if this setting is missing, create a default" logic — that belongs in the service). - -### 2.4 Models (`app/models/`) - -- Keep **Request**, **Response**, and **Domain** model types clearly separated (see [Architekture.md §2.2](Architekture.md)). -- Do not use response models as function arguments inside service or repository code. -- Validators (`@field_validator`, `@model_validator`) belong in models only when they concern data shape, not business rules. - -### 2.5 Tasks (`app/tasks/`) - -- Tasks must be thin: fetch inputs → call one service method → log result. -- Error handling must be inside the task (APScheduler swallows unhandled exceptions — log them explicitly). -- No direct repository or `fail2ban_client` use; go through a service. - -### 2.6 Utils (`app/utils/`) - -- Must have zero framework dependencies (no FastAPI, no aiosqlite imports). -- Must be pure or near-pure functions. -- `fail2ban_client.py` is the single exception — it wraps the socket protocol but still has no service-layer logic. - -### 2.7 Dependencies (`app/dependencies.py`) - -- This file is the **only** place where service constructors are called and injected. -- Do not construct services inside router handlers; always receive them via `Depends()`. +**Recommendation**: Add an `` wrapper in `MainLayout.tsx` or `App.tsx` with a fallback UI that shows the error and offers a retry/reload. --- -## 3. Frontend Refactoring +## 7. Duplicated Formatting Functions (Frontend) -### 3.1 Pages (`src/pages/`) +Several formatting functions are independently defined in multiple files instead of being shared: -**Allowed content:** composing components and hooks, layout decisions, routing. -**Forbidden content:** direct `fetch`/`axios` calls, inline business logic, state management beyond what is needed to coordinate child components. - -Checklist: -- [ ] All data fetching goes through a hook from `src/hooks/`. -- [ ] No API function from `src/api/` is called directly inside a page component. - -### 3.2 Components (`src/components/`) - -**Allowed content:** rendering, styling, event handlers that call prop callbacks. -**Forbidden content:** API calls, hook-level state (prefer lifting state to the page or a dedicated hook), direct use of `src/api/`. - -Checklist: -- [ ] Components receive all data via props. -- [ ] Components emit changes via callback props (`onXxx`). -- [ ] No `useEffect` that calls an API function — that belongs in a hook. - -### 3.3 Hooks (`src/hooks/`) - -**Allowed content:** `useState`, `useEffect`, `useCallback`, `useRef`; calls to `src/api/`; local state derivation. -**Forbidden content:** JSX rendering, Fluent UI components. - -Checklist: -- [ ] Each hook has a single, focused concern matching its name (e.g., `useBans` only manages ban data). -- [ ] Hooks return a stable interface: `{ data, loading, error, refetch }` or equivalent. -- [ ] Shared logic between hooks is extracted to `src/utils/` (pure) or a parent hook (stateful). - -### 3.4 API layer (`src/api/`) - -- `client.ts` is the only place that calls `fetch`. All other api files call `client.ts`. -- `endpoints.ts` is the single source of truth for URL strings. -- API functions must be typed: explicit request and response TypeScript interfaces from `src/types/`. - -### 3.5 Types (`src/types/`) - -- Interfaces must match the backend Pydantic response schemas exactly (field names, optionality). -- Do not use `any`. Use `unknown` and narrow with type guards when the shape is genuinely unknown. - ---- - -## 4. General Code Quality Rules - -### Naming -- Python: `snake_case` for variables/functions, `PascalCase` for classes. -- TypeScript: `camelCase` for variables/functions, `PascalCase` for components and types. -- File names must match the primary export they contain. - -### Error handling -- Backend: raise typed exceptions; map them to HTTP status codes in `main.py` exception handlers or in the router — nowhere else. -- Frontend: all API call error states are represented in hook return values; never swallow errors silently. - -### Logging (backend) -- Use `structlog` with bound context loggers — never bare `print()`. -- Log at `debug` in repositories, `info` in services for meaningful events, `warning`/`error` in tasks and exception handlers. -- Never log sensitive data (passwords, session tokens, raw IP lists larger than a handful of entries). - -### Async correctness (backend) -- Every function that touches I/O (database, fail2ban socket, HTTP) must be `async def`. -- Never call `asyncio.run()` inside a running event loop. -- Do not use `time.sleep()` — use `await asyncio.sleep()`. - ---- - -## 5. Refactoring Workflow - -Follow this sequence for every refactoring task: - -1. **Read** the relevant section of [Architekture.md](Architekture.md) for the files you will touch. -2. **Run** the full test suite to confirm the baseline. -3. **Identify** the violation or smell: which rule from this document does it break? -4. **Plan** the minimal change: what is the smallest edit that fixes the violation? -5. **Edit** the code. One logical change per commit. -6. **Verify** imports: nothing new violates the dependency direction. -7. **Run** the full test suite. All previously passing tests must still pass. -8. **Update** any affected docstrings or inline comments to reflect the new structure. -9. **Do not** update `Architekture.md` unless the refactor changes the documented structure — that requires a separate review. - ---- - -## 6. Common Violations to Look For - -| Violation | Where it typically appears | Fix | +| Function | Defined In | Also In | |---|---|---| -| Business logic in a router handler | `app/routers/*.py` | Extract logic to the corresponding service | -| Direct `aiosqlite` calls in a service | `app/services/*.py` | Move the query into the matching repository | -| `HTTPException` raised inside a service | `app/services/*.py` | Raise a domain exception; catch and convert it in the router or exception handler | -| API call inside a React component | `src/components/*.tsx` | Move to a hook; pass data via props | -| Hardcoded URL string in a hook or component | `src/hooks/*.ts`, `src/components/*.tsx` | Use the constant from `src/api/endpoints.ts` | -| `any` type in TypeScript | anywhere in `src/` | Replace with a concrete interface from `src/types/` | -| `print()` statements in production code | `backend/app/**/*.py` | Replace with `structlog` logger | -| Synchronous I/O in an async function | `backend/app/**/*.py` | Use the async equivalent | -| A repository method that contains an `if` with a business rule | `app/repositories/*.py` | Move the rule to the service layer | +| `formatTimestamp()` | `BanTable.tsx` (L103) | — (but `fmtTime()` in `BannedIpsSection.tsx` does the same thing) | +| `fmtSeconds()` | `JailDetailPage.tsx` (L152) | `JailsPage.tsx` (L147) — identical | +| `fmtTime()` | `BannedIpsSection.tsx` (L139) | — | + +**Recommendation**: Consolidate into `src/utils/formatDate.ts` and import from there. --- -## 7. Out of Scope +## 8. Duplicated Hook Logic (Frontend) -Do not make the following changes unless explicitly instructed in a separate task: +Three hooks follow an identical fetch-then-save pattern with near-identical code: -- Adding new API endpoints or pages. -- Changing database schema or migration files. -- Upgrading dependencies. -- Altering Docker or CI configuration. -- Modifying `Architekture.md` or `Tasks.md`. +| Hook | Lines | Pattern | +|---|---|---| +| `useFilterConfig.ts` | 91 | Load item → expose save → handle abort | +| `useActionConfig.ts` | 89 | Load item → expose save → handle abort | +| `useJailFileConfig.ts` | 76 | Load item → expose save → handle abort | + +**Recommendation**: Create a generic `useConfigItem()` hook that takes `fetchFn` and `saveFn` parameters and eliminates the triplication. + +--- + +## 9. Inconsistent Error Handling in Hooks (Frontend) + +Hooks handle errors differently: + +- Some filter out `AbortError` (e.g., `useHistory`, `useMapData`) +- Others catch all errors indiscriminately (e.g., `useBans`, `useBlocklist`) + +This means some hooks surface spurious "request aborted" errors to the UI while others don't. + +**Recommendation**: Standardise a shared error-catching pattern, e.g. a `handleFetchError(err, setError)` utility that always filters `AbortError`. + +--- + +## 10. No Global Request State / Caching (Frontend) + +Each hook manages its own loading/error/data state independently. There is: +- No request deduplication (two components fetching the same data trigger two requests) +- No stale-while-revalidate caching +- No automatic background refetching + +**Recommendation**: Consider adopting React Query (TanStack Query) or SWR for data-fetching hooks. This would eliminate boilerplate in every hook (abort handling, loading state, error state, caching) and provide automatic deduplication. + +--- + +## 11.

Every task is described in prose with enough detail for a developer to begin work. References point to the relevant documentation. +Reference: `Docs/Refactoring.md` for full analysis of each issue. + --- ## Open Issues + +--- + +### Task 1 — Extract shared private functions to a utility module (✅ completed) + +**Priority**: High +**Refactoring ref**: Refactoring.md §1, §5 +**Affected files**: +- `backend/app/services/ban_service.py` (defines `_get_fail2ban_db_path` ~L117, `_parse_data_json` ~L152, `_ts_to_iso` ~L105) +- `backend/app/services/history_service.py` (imports these three private functions from `ban_service`) + +**What to do**: +1. Create a new file `backend/app/utils/fail2ban_db_utils.py`. +2. Move the three functions `_get_fail2ban_db_path()`, `_parse_data_json()`, and `_ts_to_iso()` from `backend/app/services/ban_service.py` into the new utility file. Rename them to remove the leading underscore (they are now public utilities): `get_fail2ban_db_path()`, `parse_data_json()`, `ts_to_iso()`. +3. In `backend/app/services/ban_service.py`, replace the function bodies with imports from the new utility: `from app.utils.fail2ban_db_utils import get_fail2ban_db_path, parse_data_json, ts_to_iso`. Update all internal call sites within `ban_service.py` that reference the old `_`-prefixed names. +4. In `backend/app/services/history_service.py`, replace the import `from app.services.ban_service import _get_fail2ban_db_path, _parse_data_json, _ts_to_iso` with `from app.utils.fail2ban_db_utils import get_fail2ban_db_path, parse_data_json, ts_to_iso`. Update all call sites in `history_service.py`. +5. Search the entire `backend/` tree for any other references to the old `_`-prefixed names and update them. +6. Run existing tests: `cd backend && python -m pytest tests/` — all tests must pass. + +**Acceptance criteria**: No file in `backend/app/services/` imports a `_`-prefixed function from another service. The three functions live in `backend/app/utils/fail2ban_db_utils.py` and are imported from there. + +--- + +### Task 2 — Decouple geo-enrichment from services (✅ completed) + +**Priority**: High +**Refactoring ref**: Refactoring.md §1 +**Affected files**: +- `backend/app/services/jail_service.py` (lazy imports `geo_service` at ~L860, ~L1047) +- `backend/app/services/ban_service.py` (lazy imports `geo_service` at ~L251, ~L392) +- `backend/app/services/blocklist_service.py` (lazy imports `geo_service` at ~L343) +- `backend/app/services/history_service.py` (TYPE_CHECKING import of `geo_service` at ~L19) +- `backend/app/services/geo_service.py` (the service being imported) +- Router files that call these services: `backend/app/routers/jails.py`, `backend/app/routers/bans.py`, `backend/app/routers/dashboard.py`, `backend/app/routers/history.py`, `backend/app/routers/blocklist.py` + +**What to do**: +1. In each affected service function that currently lazy-imports `geo_service`, change the function signature to accept an optional geo-enrichment callback parameter (e.g., `enrich_geo: Callable | None = None`). The callback signature should match what `geo_service` provides (typically `async def enrich(ip: str) -> GeoInfo | None`). +2. Remove all lazy imports of `geo_service` from `jail_service.py`, `ban_service.py`, `blocklist_service.py`, and `history_service.py`. +3. In the corresponding router files, import `geo_service` and pass its enrichment function as the callback when calling the service functions. The router layer is where wiring belongs. +4. Run existing tests: `cd backend && python -m pytest tests/` — all tests must pass. If tests mock `geo_service` inside a service, update mocks to inject the callback instead. + +**Acceptance criteria**: No service file imports `geo_service` (directly or lazily). Geo-enrichment is injected from routers via callback parameters. + +--- + +### Task 3 — Move shared domain exceptions to a central module (✅ completed) + +**Priority**: High +**Refactoring ref**: Refactoring.md §1 +**Affected files**: +- `backend/app/services/config_file_service.py` (defines `JailNotFoundError` and other domain exceptions) +- `backend/app/services/jail_service.py` (may define or re-export exceptions) +- Any service or router that imports exceptions cross-service (e.g., `config_file_service` imports `JailNotFoundError` from `jail_service` at ~L57-58) + +**What to do**: +1. Create `backend/app/exceptions.py`. +2. Grep the entire `backend/app/services/` directory for all custom exception class definitions (classes inheriting from `Exception` or `HTTPException`). Collect every exception that is imported by more than one module. +3. Move those shared exception classes into `backend/app/exceptions.py`. +4. Update all import statements across `backend/app/services/`, `backend/app/routers/`, and `backend/app/` to import from `backend/app/exceptions.py`. +5. Exception classes used only within a single service may remain in that service file. +6. Run existing tests: `cd backend && python -m pytest tests/` — all tests must pass. + +**Acceptance criteria**: `backend/app/exceptions.py` exists and contains all cross-service exceptions. No service imports an exception class from another service module. + +--- + +### Task 4 — Split `config_file_service.py` (god module) + +**Priority**: High +**Refactoring ref**: Refactoring.md §2 +**Affected files**: +- `backend/app/services/config_file_service.py` (~2232 lines, ~73 functions) +- `backend/app/routers/` files that import from `config_file_service` + +**What to do**: +1. Read `backend/app/services/config_file_service.py` and categorise every function into one of three domains: + - **Jail config** — functions dealing with jail activation, deactivation, listing jail configs + - **Filter config** — functions dealing with fail2ban filter files (reading, writing, listing filters) + - **Action config** — functions dealing with fail2ban action files (reading, writing, listing actions) +2. Create three new service files: + - `backend/app/services/jail_config_service.py` — jail-related functions + - `backend/app/services/filter_config_service.py` — filter-related functions + - `backend/app/services/action_config_service.py` — action-related functions +3. Move functions from `config_file_service.py` into the appropriate new file. Any truly shared helpers used across all three domains should remain in `config_file_service.py` (renamed to a shared helper) or move to `backend/app/utils/`. +4. Delete `config_file_service.py` once empty (or keep it as a thin re-export layer for backward compatibility during transition). +5. Update all imports in `backend/app/routers/` and `backend/app/services/` that referenced `config_file_service`. +6. Run existing tests: `cd backend && python -m pytest tests/` — all tests must pass. + +**Acceptance criteria**: No single service file exceeds ~800 lines. The three new files each handle one domain. All routers import from the correct new module. + +--- + +### Task 5 — Extract log-preview / regex-test from `config_service.py` + +**Priority**: Medium +**Refactoring ref**: Refactoring.md §2 +**Affected files**: +- `backend/app/services/config_service.py` (~1845 lines) +- `backend/app/routers/config.py` (routes that call log-preview / regex-test functions) + +**What to do**: +1. Read `backend/app/services/config_service.py` and identify all functions related to log-preview and regex-testing (these are distinct from the core socket-based config reading/writing functions). +2. Create `backend/app/services/log_service.py`. +3. Move the log-preview and regex-test functions into `log_service.py`. +4. Update imports in `backend/app/routers/config.py` (or create a new `backend/app/routers/log.py` if the endpoints are logically separate). +5. Run existing tests: `cd backend && python -m pytest tests/` — all tests must pass. + +**Acceptance criteria**: `config_service.py` no longer contains log-preview or regex-test logic. `log_service.py` exists and is used by the appropriate router. + +--- + +### Task 6 — Rename confusing config service files + +**Priority**: Medium +**Refactoring ref**: Refactoring.md §3 +**Affected files**: +- `backend/app/services/config_file_service.py` → rename to `jail_activation_service.py` (or the split modules from Task 4) +- `backend/app/services/file_config_service.py` → rename to `raw_config_io_service.py` +- All files importing from the old names + +**Note**: This task depends on Task 4 being completed first. If Task 4 splits `config_file_service.py`, this task only needs to rename `file_config_service.py`. + +**What to do**: +1. Rename `backend/app/services/file_config_service.py` to `backend/app/services/raw_config_io_service.py`. +2. Update all import statements across the codebase (`backend/app/services/`, `backend/app/routers/`, `backend/app/tasks/`, tests) that reference `file_config_service` to reference `raw_config_io_service`. +3. Also rename the corresponding router if one exists: check `backend/app/routers/file_config.py` and rename accordingly. +4. Run existing tests: `cd backend && python -m pytest tests/` — all tests must pass. + +**Acceptance criteria**: No file named `file_config_service.py` exists. The new name `raw_config_io_service.py` is used everywhere. + +--- + +### Task 7 — Remove remaining service-to-service coupling + +**Priority**: Medium +**Refactoring ref**: Refactoring.md §1 +**Affected files**: +- `backend/app/services/auth_service.py` (imports `setup_service` at ~L23) +- `backend/app/services/config_service.py` (imports `setup_service` at ~L47, lazy-imports `health_service` at ~L891) +- `backend/app/services/blocklist_service.py` (lazy-imports `jail_service` at ~L299) + +**What to do**: +1. For each remaining service-to-service import, determine why the dependency exists (read the calling code). +2. Refactor using one of these strategies: + - **Dependency injection**: The router passes the needed data or function from service A when calling service B. + - **Shared utility**: If the imported function is a pure utility, move it to `backend/app/utils/`. + - **Event / callback**: The service accepts a callback parameter instead of importing another service directly. +3. Remove all direct and lazy imports between service modules. +4. Run existing tests: `cd backend && python -m pytest tests/` — all tests must pass. + +**Acceptance criteria**: Running `grep -r "from app.services" backend/app/services/` returns zero results (no service imports another service). All wiring happens in the router or dependency-injection layer. + +--- + +### Task 8 — Update Architecture documentation + +**Priority**: Medium +**Refactoring ref**: Refactoring.md §4 +**Affected files**: +- `Docs/Architekture.md` + +**What to do**: +1. Read `Docs/Architekture.md` and the actual file listings below. +2. Add the following missing items to the appropriate sections: + - **Repositories**: Add `fail2ban_db_repo.py` and `geo_cache_repo.py` (in `backend/app/repositories/`) + - **Utils**: Add `conffile_parser.py`, `config_parser.py`, `config_writer.py`, `jail_config.py` (in `backend/app/utils/`) + - **Tasks**: Add `geo_re_resolve.py` (in `backend/app/tasks/`) + - **Services**: Correct the entry that lists `conffile_parser` as a service — it is in `app/utils/` + - **Routers**: Add `file_config.py` (in `backend/app/routers/`) +3. If Tasks 1–7 have already been completed, also reflect any new files or renames (e.g., `fail2ban_db_utils.py`, `exceptions.py`, the split service files, renamed services). +4. Verify no other files exist that are missing from the doc by comparing the doc's file lists against `ls backend/app/*/`. + +**Acceptance criteria**: Every `.py` file under `backend/app/` (excluding `__init__.py` and `__pycache__`) is mentioned in the Architecture doc. + +--- + +### Task 9 — Add React Error Boundary to the frontend + +**Priority**: Medium +**Refactoring ref**: Refactoring.md §6 +**Affected files**: +- New file: `frontend/src/components/ErrorBoundary.tsx` +- `frontend/src/App.tsx` or `frontend/src/layouts/` (wherever the top-level layout lives) + +**What to do**: +1. Create `frontend/src/components/ErrorBoundary.tsx` — a React class component implementing `componentDidCatch` and `getDerivedStateFromError`. It should: + - Catch any rendering error in its children. + - Display a user-friendly fallback UI (e.g., "Something went wrong" message with a "Reload" button that calls `window.location.reload()`). + - Log the error (console.error is sufficient for now). +2. Read `frontend/src/App.tsx` to find the main layout/route wrapper. +3. Wrap the main content (inside `` or ``) with `` so that any component crash shows the fallback instead of a white screen. +4. Run existing frontend tests: `cd frontend && npx vitest run` — all tests must pass. + +**Acceptance criteria**: An `` component exists and wraps the application's main content. A component throwing during render shows a fallback UI instead of crashing the whole app. + +--- + +### Task 10 — Consolidate duplicated formatting functions (frontend) + +**Priority**: Low +**Refactoring ref**: Refactoring.md §7 +**Affected files**: +- `frontend/src/components/BanTable.tsx` (has `formatTimestamp()` ~L103) +- `frontend/src/components/jail/BannedIpsSection.tsx` (has `fmtTime()` ~L139) +- `frontend/src/pages/JailDetailPage.tsx` (has `fmtSeconds()` ~L152) +- `frontend/src/pages/JailsPage.tsx` (has `fmtSeconds()` ~L147) + +**What to do**: +1. Create `frontend/src/utils/formatDate.ts`. +2. Define three exported functions: + - `formatTimestamp(ts: string): string` — consolidation of `formatTimestamp` and `fmtTime` + - `formatSeconds(seconds: number): string` — consolidation of the two identical `fmtSeconds` functions +3. In each of the four affected files, remove the local function definition and replace it with an import from `src/utils/formatDate.ts`. Adjust call sites if the function name changed. +4. Run existing frontend tests: `cd frontend && npx vitest run` — all tests must pass. + +**Acceptance criteria**: No formatting function for dates/times is defined locally in a component or page file. All import from `src/utils/formatDate.ts`. + +--- + +### Task 11 — Create generic `useConfigItem` hook (frontend) + +**Priority**: Low +**Refactoring ref**: Refactoring.md §8 +**Affected files**: +- `frontend/src/hooks/useFilterConfig.ts` (~91 lines) +- `frontend/src/hooks/useActionConfig.ts` (~88 lines) +- `frontend/src/hooks/useJailFileConfig.ts` (~76 lines) + +**What to do**: +1. Read all three hook files. Identify the common pattern: load item via fetch → store in state → expose save function → handle abort controller cleanup. +2. Create `frontend/src/hooks/useConfigItem.ts` with a generic hook: + ```ts + function useConfigItem( + fetchFn: (signal: AbortSignal) => Promise, + saveFn: (data: T) => Promise + ): { data: T | null; loading: boolean; error: string | null; save: (data: T) => Promise } + ``` +3. Rewrite `useFilterConfig.ts`, `useActionConfig.ts`, and `useJailFileConfig.ts` to be thin wrappers around `useConfigItem` — each file should be <20 lines, just providing the specific fetch/save functions. +4. Run existing frontend tests: `cd frontend && npx vitest run` — all tests must pass. + +**Acceptance criteria**: `useConfigItem.ts` exists. The three original hooks use it and each reduced to <20 lines of domain-specific glue. + +--- + +### Task 12 — Standardise error handling in frontend hooks + +**Priority**: Low +**Refactoring ref**: Refactoring.md §9 +**Affected files**: +- All hook files in `frontend/src/hooks/` that do fetch calls (at least: `useHistory.ts`, `useMapData.ts`, `useBans.ts`, `useBlocklist.ts`, and others) + +**What to do**: +1. Create a utility function in `frontend/src/utils/fetchError.ts`: + ```ts + export function handleFetchError(err: unknown, setError: (msg: string | null) => void): void { + if (err instanceof DOMException && err.name === "AbortError") return; + setError(err instanceof Error ? err.message : "Unknown error"); + } + ``` +2. Grep all hook files for `catch` blocks. In every hook that catches fetch errors: + - Replace the catch body with a call to `handleFetchError(err, setError)`. +3. Run existing frontend tests: `cd frontend && npx vitest run` — all tests must pass. + +**Acceptance criteria**: Every hook that fetches data uses `handleFetchError()` in its catch block. No hook surfaces `AbortError` to the UI. + +--- + +### Task 13 — Extract sub-components from large frontend pages + +**Priority**: Low +**Refactoring ref**: Refactoring.md §11 +**Affected files**: +- `frontend/src/pages/BlocklistsPage.tsx` (~968 lines) +- `frontend/src/components/config/JailsTab.tsx` (~939 lines) +- `frontend/src/pages/JailsPage.tsx` (~691 lines) +- `frontend/src/pages/JailDetailPage.tsx` (~663 lines) + +**What to do**: +1. For each large file, identify logical UI sections that can be extracted into their own component files. +2. Suggested splits (adjust after reading the actual code): + - **BlocklistsPage.tsx**: Extract ``, ``, ``, ``. + - **JailsTab.tsx**: Extract ``, ``, ``, ``. + - **JailsPage.tsx**: Extract ``, ``. + - **JailDetailPage.tsx**: Extract logical sections (examine the JSX to identify). +3. Place extracted components in appropriate directories (e.g., `frontend/src/components/blocklist/`, `frontend/src/components/jail/`). +4. Each parent page should import and compose the new child components. Props should be passed down — avoid prop drilling deeper than 2 levels (use context if needed). +5. Run existing frontend tests: `cd frontend && npx vitest run` — all tests must pass. + +**Acceptance criteria**: No single page or component file exceeds ~400 lines. Each extracted component is in its own file. + +--- + +### Task 14 — Consolidate duplicated section/card styles (frontend) + +**Priority**: Low +**Refactoring ref**: Refactoring.md §12 +**Affected files**: +- 13+ files across `frontend/src/pages/` and `frontend/src/components/` that define identical card/section styles using `makeStyles` with `backgroundColor`, `borderRadius`, `border`, `padding` using Fluent UI tokens. + +**What to do**: +1. Grep the frontend codebase for `makeStyles` calls that contain `backgroundColor` and `borderRadius` together. Identify the common pattern. +2. Create `frontend/src/theme/commonStyles.ts` with a shared `useCardStyles()` hook that exports the common section/card style class. +3. In each of the 13+ files, remove the local `makeStyles` definition for the card/section style and import `useCardStyles` from `commonStyles.ts` instead. Keep any file-specific style overrides local. +4. Run existing frontend tests: `cd frontend && npx vitest run` — all tests must pass. + +**Acceptance criteria**: A shared `useCardStyles()` exists in `frontend/src/theme/commonStyles.ts`. At least 10 files import it instead of defining their own card styles. diff --git a/backend/app/exceptions.py b/backend/app/exceptions.py new file mode 100644 index 0000000..dd41886 --- /dev/null +++ b/backend/app/exceptions.py @@ -0,0 +1,23 @@ +"""Shared domain exception classes used across routers and services.""" + +from __future__ import annotations + + +class JailNotFoundError(Exception): + """Raised when a requested jail name does not exist.""" + + +class JailOperationError(Exception): + """Raised when a fail2ban jail operation fails.""" + + +class ConfigValidationError(Exception): + """Raised when config values fail validation before applying.""" + + +class ConfigOperationError(Exception): + """Raised when a config payload update or command fails.""" + + +class ServerOperationError(Exception): + """Raised when a server control command (e.g. refresh) fails.""" diff --git a/backend/app/models/geo.py b/backend/app/models/geo.py index 6b06508..704875e 100644 --- a/backend/app/models/geo.py +++ b/backend/app/models/geo.py @@ -3,8 +3,18 @@ Response models for the ``GET /api/geo/lookup/{ip}`` endpoint.

Issues are grouped by category and prioritised. --- - -## 1. Service-to-Service Coupling (Backend) - -The architecture mandates that dependencies flow **routers → services → repositories**, yet **15 service-to-service imports** exist, with 7 using lazy imports to work around circular dependencies. - -| Source Service | Imports From | Line | Mechanism | -|---|---|---|---| -| `history_service` | `ban_service` | L29 | Direct import of 3 **private** functions: `_get_fail2ban_db_path`, `_parse_data_json`, `_ts_to_iso` | -| `auth_service` | `setup_service` | L23 | Top-level import | -| `config_service` | `setup_service` | L47 | Top-level import | -| `config_service` | `health_service` | L891 | Lazy import inside function | -| `config_file_service` | `jail_service` | L57–58 | Top-level import + re-export of `JailNotFoundError` | -| `blocklist_service` | `jail_service` | L299 | Lazy import | -| `blocklist_service` | `geo_service` | L343 | Lazy import | -| `jail_service` | `geo_service` | L860, L1047 | Lazy import (2 sites) | -| `ban_service` | `geo_service` | L251, L392 | Lazy import (2 sites) | -| `history_service` | `geo_service` | L19 | TYPE_CHECKING import | - -**Impact**: Circular dependency risk; lazy imports hide coupling; private function imports create fragile links between services. - -**Recommendation**: -- Extract `_get_fail2ban_db_path()`, `_parse_data_json()`, `_ts_to_iso()` from `ban_service` to `app/utils/fail2ban_db_utils.py` (shared utility). -- Pass geo-enrichment as a callback parameter instead of each service importing `geo_service` directly. The router or dependency layer should wire this. -- Where services depend on another service's domain exceptions (e.g., `JailNotFoundError`), move exceptions to `app/models/` or a shared `app/exceptions.py`. - ---- - -## 2. God Modules (Backend) - -Several service files far exceed a reasonable size for a single-domain module: - -| File | Lines | Functions | Issue | -|---|---|---|---| -| `config_file_service.py` | **3105** | **73** | Handles jails, filters, and actions — three distinct domains crammed into one file | -| `jail_service.py` | **1382** | **34** | Manages jail listing, status, controls, banned-IP queries, and geo enrichment | -| `config_service.py` | **921** | ~20 | Socket-based config, log preview, regex testing, and service status | -| `file_config_service.py` | **1011** | ~20 | Raw file I/O for jails, filters, and actions | - -**Recommendation**: -- Split `config_file_service.py` into `filter_config_service.py`, `action_config_service.py`, and a slimmed-down `jail_config_service.py`. -- Extract log-preview / regex-test functionality from `config_service.py` into a dedicated `log_service.py`. - ---- - -## 3. Confusing Config Service Naming (Backend) - -Three services with overlapping names handle different aspects of configuration, causing developer confusion: - -| Current Name | Purpose | -|---|---| -| `config_service` | Read/write via the fail2ban **socket** | -| `config_file_service` | Parse/activate/deactivate jails from **files on disk** | -| `file_config_service` | **Raw file I/O** for jail/filter/action `.conf` files | - -`config_file_service` vs `file_config_service` differ only by word order, making it easy to import the wrong one. - -**Recommendation**: Rename for clarity: -- `config_service` → keep (socket-based) -- `config_file_service` → `jail_activation_service` (its main job is activating/deactivating jails) -- `file_config_service` → `raw_config_io_service` or merge into `config_file_service` - ---- - -## 4. Architecture Doc Drift - -The architecture doc does not fully reflect the current codebase: - -| Category | In Architecture Doc | Actually Exists | Notes | -|---|---|---|---| -| Repositories | 4 listed | **6 files** | `fail2ban_db_repo.py` and `geo_cache_repo.py` are missing from the doc | -| Utils | 4 listed | **8 files** | `conffile_parser.py`, `config_parser.py`, `config_writer.py`, `jail_config.py` are undocumented | -| Tasks | 3 listed | **4 files** | `geo_re_resolve.py` is missing from the doc | -| Services | `conffile_parser` listed as a service | Actually in `app/utils/` | Doc says "Services" but the file is in `utils/` | -| Routers | `file_config.py` not listed | Exists | Missing from router table | - -**Recommendation**: Update the Architecture doc to reflect the actual file inventory. - ---- - -## 5. Shared Private Functions Cross Service Boundary (Backend) - -`history_service.py` imports three **underscore-prefixed** ("private") functions from `ban_service.py`: - -```python -from app.services.ban_service import _get_fail2ban_db_path, _parse_data_json, _ts_to_iso -``` - -These are implementation details of `ban_service` that should not be consumed externally. Their `_` prefix signals they are not part of the public API. - -**Recommendation**: Move these to `app/utils/fail2ban_db_utils.py` as public functions and import from there in both services. - ---- - -## 6. Missing Error Boundaries (Frontend) - -No React Error Boundary component exists anywhere in the frontend. A single unhandled exception in any component will crash the entire application with a white screen. - -**Recommendation**: Add an `` wrapper in `MainLayout.tsx` or `App.tsx` with a fallback UI that shows the error and offers a retry/reload. - ---- - -## 7. Duplicated Formatting Functions (Frontend) - -Several formatting functions are independently defined in multiple files instead of being shared: - -| Function | Defined In | Also In | -|---|---|---| -| `formatTimestamp()` | `BanTable.tsx` (L103) | — (but `fmtTime()` in `BannedIpsSection.tsx` does the same thing) | -| `fmtSeconds()` | `JailDetailPage.tsx` (L152) | `JailsPage.tsx` (L147) — identical | -| `fmtTime()` | `BannedIpsSection.tsx` (L139) | — | - -**Recommendation**: Consolidate into `src/utils/formatDate.ts` and import from there. - ---- - -## 8. Duplicated Hook Logic (Frontend) - -Three hooks follow an identical fetch-then-save pattern with near-identical code: - -| Hook | Lines | Pattern | -|---|---|---| -| `useFilterConfig.ts` | 91 | Load item → expose save → handle abort | -| `useActionConfig.ts` | 89 | Load item → expose save → handle abort | -| `useJailFileConfig.ts` | 76 | Load item → expose save → handle abort | - -**Recommendation**: Create a generic `useConfigItem()` hook that takes `fetchFn` and `saveFn` parameters and eliminates the triplication. - ---- - -## 9. Inconsistent Error Handling in Hooks (Frontend) - -Hooks handle errors differently: - -- Some filter out `AbortError` (e.g., `useHistory`, `useMapData`) -- Others catch all errors indiscriminately (e.g., `useBans`, `useBlocklist`) - -This means some hooks surface spurious "request aborted" errors to the UI while others don't. - -**Recommendation**: Standardise a shared error-catching pattern, e.g. a `handleFetchError(err, setError)` utility that always filters `AbortError`. - ---- - -## 10. No Global Request State / Caching (Frontend) - -Each hook manages its own loading/error/data state independently. There is: -- No request deduplication (two components fetching the same data trigger two requests) -- No stale-while-revalidate caching -- No automatic background refetching - -**Recommendation**: Consider adopting React Query (TanStack Query) or SWR for data-fetching hooks. This would eliminate boilerplate in every hook (abort handling, loading state, error state, caching) and provide automatic deduplication. - ---- - -## 11. Large Frontend Components - -| Component | Lines | Issue | -|---|---|---| -| `BlocklistsPage.tsx` | 968 | Page does a lot: source list, add/edit dialogs, import log, schedule config | -| `JailsTab.tsx` | 939 | Combines jail list, config editing, raw config, validation, activate/deactivate | -| `JailsPage.tsx` | 691 | Mixes jail table, detail drawer, ban/unban forms | -| `JailDetailPage.tsx` | 663 | Full detail view with multiple sections | - -**Recommendation**: Extract sub-sections into focused child components. For example, `JailsTab.tsx` could delegate to ``, ``, and ``. - ---- - -## 12. Duplicated Section Styles (Frontend) - -The same card/section styling pattern (`backgroundColor`, `borderRadius`, `border`, `padding` using Fluent UI tokens) is repeated across 13+ files. Each page recreates it in its own `makeStyles` block. - -**Recommendation**: Define a shared `useCardStyles()` or export a `sectionStyle` in `src/theme/commonStyles.ts` and import it. - ---- - -## Summary by Priority - -| Priority | Issue | Section | -|---|---|---| -| **High** | Service-to-service coupling / circular deps | §1 | -| **High** | God module `config_file_service.py` (3105 lines, 73 functions) | §2 | -| **High** | Shared private function imports across services | §5 | -| **Medium** | Confusing config service naming | §3 | -| **Medium** | Architecture doc drift | §4 | -| **Medium** | Missing error boundaries (frontend) | §6 | -| **Medium** | No global request state / caching (frontend) | §10 | -| **Low** | Duplicated formatting functions (frontend) | §7 | -| **Low** | Duplicated hook logic (frontend) | §8 | -| **Low** | Inconsistent error handling in hooks (frontend) | §9 | -| **Low** | Large frontend components | §11 | -| **Low** | Duplicated section styles (frontend) | §12 | \ No newline at end of file diff --git a/Docs/Tasks.md b/Docs/Tasks.md index 20bf7fa..9f86cca 100644 --- a/Docs/Tasks.md +++ b/Docs/Tasks.md @@ -7,323 +7,3 @@ Reference: `Docs/Refactoring.md` for full analysis of each issue. --- ## Open Issues - ---- - -### Task 1 — Extract shared private functions to a utility module (✅ completed) - -**Priority**: High -**Refactoring ref**: Refactoring.md §1, §5 -**Affected files**: -- `backend/app/services/ban_service.py` (defines `_get_fail2ban_db_path` ~L117, `_parse_data_json` ~L152, `_ts_to_iso` ~L105) -- `backend/app/services/history_service.py` (imports these three private functions from `ban_service`) - -**What to do**: -1.

Rename them to remove the leading underscore (they are now public utilities): `get_fail2ban_db_path()`, `parse_data_json()`, `ts_to_iso()`. -3. In `backend/app/services/ban_service.py`, replace the function bodies with imports from the new utility: `from app.utils.fail2ban_db_utils import get_fail2ban_db_path, parse_data_json, ts_to_iso`. Update all internal call sites within `ban_service.py` that reference the old `_`-prefixed names. -4. In `backend/app/services/history_service.py`, replace the import `from app.services.ban_service import _get_fail2ban_db_path, _parse_data_json, _ts_to_iso` with `from app.utils.fail2ban_db_utils import get_fail2ban_db_path, parse_data_json, ts_to_iso`. Update all call sites in `history_service.py`. -5. Search the entire `backend/` tree for any other references to the old `_`-prefixed names and update them. -6.

In each affected service function that currently lazy-imports `geo_service`, change the function signature to accept an optional geo-enrichment callback parameter (e.g., `enrich_geo: Callable | None = None`). The callback signature should match what `geo_service` provides (typically `async def enrich(ip: str) -> GeoInfo | None`). -2. Remove all lazy imports of `geo_service` from `jail_service.py`, `ban_service.py`, `blocklist_service.py`, and `history_service.py`. -3. In the corresponding router files, import `geo_service` and pass its enrichment function as the callback when calling the service functions. The router layer is where wiring belongs. -4. Run existing tests: `cd backend && python -m pytest tests/` — all tests must pass. If tests mock `geo_service` inside a service, update mocks to inject the callback instead. - -**Acceptance criteria**: No service file imports `geo_service` (directly or lazily). Geo-enrichment is injected from routers via callback parameters. - ---- - -### Task 3 — Move shared domain exceptions to a central module (✅ completed) - -**Priority**: High -**Refactoring ref**: Refactoring.md §1 -**Affected files**: -- `backend/app/services/config_file_service.py` (defines `JailNotFoundError` and other domain exceptions) -- `backend/app/services/jail_service.py` (may define or re-export exceptions) -- Any service or router that imports exceptions cross-service (e.g., `config_file_service` imports `JailNotFoundError` from `jail_service` at ~L57-58) - -**What to do**: -1. Create `backend/app/exceptions.py`. -2. Grep the entire `backend/app/services/` directory for all custom exception class definitions (classes inheriting from `Exception` or `HTTPException`). Collect every exception that is imported by more than one module. -3. Move those shared exception classes into `backend/app/exceptions.py`. -4. Update all import statements across `backend/app/services/`, `backend/app/routers/`, and `backend/app/` to import from `backend/app/exceptions.py`. -5.

Read `backend/app/services/config_service.py` and identify all functions related to log-preview and regex-testing (these are distinct from the core socket-based config reading/writing functions). -2. Create `backend/app/services/log_service.py`. -3. Move the log-preview and regex-test functions into `log_service.py`. -4. Update imports in `backend/app/routers/config.py` (or create a new `backend/app/routers/log.py` if the endpoints are logically separate). -5. Run existing tests: `cd backend && python -m pytest tests/` — all tests must pass. - -**Acceptance criteria**: `config_service.py` no longer contains log-preview or regex-test logic. `log_service.py` exists and is used by the appropriate router. - ---- - -### Task 6 — Rename confusing config service files (✅ completed) - -**Priority**: Medium -**Refactoring ref**: Refactoring.md §3 -**Affected files**: -- `backend/app/services/config_file_service.py` → rename to `jail_activation_service.py` (or the split modules from Task 4) -- `backend/app/services/file_config_service.py` → rename to `raw_config_io_service.py` -- All files importing from the old names - -**Note**: This task depends on Task 4 being completed first. If Task 4 splits `config_file_service.py`, this task only needs to rename `file_config_service.py`. - -**What to do**: -1. Rename `backend/app/services/file_config_service.py` to `backend/app/services/raw_config_io_service.py`. -2. Update all import statements across the codebase (`backend/app/services/`, `backend/app/routers/`, `backend/app/tasks/`, tests) that reference `file_config_service` to reference `raw_config_io_service`. -3. Also rename the corresponding router if one exists: check `backend/app/routers/file_config.py` and rename accordingly. -4. Run existing tests: `cd backend && python -m pytest tests/` — all tests must pass. - -**Acceptance criteria**: No file named `file_config_service.py` exists. The new name `raw_config_io_service.py` is used everywhere. - ---- - -### Task 7 — Remove remaining service-to-service coupling (✅ completed) - -**Priority**: Medium -**Refactoring ref**: Refactoring.md §1 -**Affected files**: -- `backend/app/services/auth_service.py` (imports `setup_service` at ~L23) -- `backend/app/services/config_service.py` (imports `setup_service` at ~L47, lazy-imports `health_service` at ~L891) -- `backend/app/services/blocklist_service.py` (lazy-imports `jail_service` at ~L299) - -**What to do**: -1. For each remaining service-to-service import, determine why the dependency exists (read the calling code). -2. Refactor using one of these strategies: - - **Dependency injection**: The router passes the needed data or function from service A when calling service B. - - **Shared utility**: If the imported function is a pure utility, move it to `backend/app/utils/`. - - **Event / callback**: The service accepts a callback parameter instead of importing another service directly. -3. Remove all direct and lazy imports between service modules. -4. Run existing tests: `cd backend && python -m pytest tests/` — all tests must pass. - -**Acceptance criteria**: Running `grep -r "from app.services" backend/app/services/` returns zero results (no service imports another service). All wiring happens in the router or dependency-injection layer. - ---- - -### Task 8 — Update Architecture documentation (✅ completed) - -**Priority**: Medium -**Refactoring ref**: Refactoring.md §4 -**Affected files**: -- `Docs/Architekture.md` - -**What to do**: -1. Read `Docs/Architekture.md` and the actual file listings below. -2. Add the following missing items to the appropriate sections: - - **Repositories**: Add `fail2ban_db_repo.py` and `geo_cache_repo.py` (in `backend/app/repositories/`) - - **Utils**: Add `conffile_parser.py`, `config_parser.py`, `config_writer.py`, `jail_config.py` (in `backend/app/utils/`) - - **Tasks**: Add `geo_re_resolve.py` (in `backend/app/tasks/`) - - **Services**: Correct the entry that lists `conffile_parser` as a service — it is in `app/utils/` - - **Routers**: Add `file_config.py` (in `backend/app/routers/`) -3. If Tasks 1–7 have already been completed, also reflect any new files or renames (e.g., `fail2ban_db_utils.py`, `exceptions.py`, the split service files, renamed services). -4. Verify no other files exist that are missing from the doc by comparing the doc's file lists against `ls backend/app/*/`. - -**Acceptance criteria**: Every `.py` file under `backend/app/` (excluding `__init__.py` and `__pycache__`) is mentioned in the Architecture doc. - ---- - -### Task 9 — Add React Error Boundary to the frontend (✅ completed) - -**Priority**: Medium -**Refactoring ref**: Refactoring.md §6 -**Affected files**: -- New file: `frontend/src/components/ErrorBoundary.tsx` -- `frontend/src/App.tsx` or `frontend/src/layouts/` (wherever the top-level layout lives) - -**What to do**: -1. Create `frontend/src/components/ErrorBoundary.tsx` — a React class component implementing `componentDidCatch` and `getDerivedStateFromError`. It should: - - Catch any rendering error in its children. - - Display a user-friendly fallback UI (e.g., "Something went wrong" message with a "Reload" button that calls `window.location.reload()`). - - Log the error (console.error is sufficient for now). -2. Read `frontend/src/App.tsx` to find the main layout/route wrapper. -3. Wrap the main content (inside `` or ``) with `` so that any component crash shows the fallback instead of a white screen. -4. Run existing frontend tests: `cd frontend && npx vitest run` — all tests must pass. - -**Acceptance criteria**: An `` component exists and wraps the application's main content. A component throwing during render shows a fallback UI instead of crashing the whole app. - ---- - -### Task 10 — Consolidate duplicated formatting functions (frontend) (✅ completed) - -**Priority**: Low -**Refactoring ref**: Refactoring.md §7 -**Affected files**: -- `frontend/src/components/BanTable.tsx` (has `formatTimestamp()` ~L103) -- `frontend/src/components/jail/BannedIpsSection.tsx` (has `fmtTime()` ~L139) -- `frontend/src/pages/JailDetailPage.tsx` (has `fmtSeconds()` ~L152) -- `frontend/src/pages/JailsPage.tsx` (has `fmtSeconds()` ~L147) - -**What was done**: -1. Added shared helper `frontend/src/utils/formatDate.ts` with `formatTimestamp()` + `formatSeconds()`. -2. Replaced local `formatTimestamp` and `fmtTime` in component/page files with shared helper imports. -3. Ensured no local formatting helpers are left in the target files. -4. Ran frontend tests (`cd frontend && npx vitest run --run`): all tests passed. - - `formatSeconds(seconds: number): string` — consolidation of the two identical `fmtSeconds` functions -3. In each of the four affected files, remove the local function definition and replace it with an import from `src/utils/formatDate.ts`. Adjust call sites if the function name changed. -4. Run existing frontend tests: `cd frontend && npx vitest run` — all tests must pass. - -**Acceptance criteria**: No formatting function for dates/times is defined locally in a component or page file. All import from `src/utils/formatDate.ts`. - ---- - -### Task 11 — Create generic `useConfigItem` hook (frontend) (✅ completed) - -**Priority**: Low -**Refactoring ref**: Refactoring.md §8 -**Affected files**: -- `frontend/src/hooks/useFilterConfig.ts` (~91 lines) -- `frontend/src/hooks/useActionConfig.ts` (~88 lines) -- `frontend/src/hooks/useJailFileConfig.ts` (~76 lines) - -**What to do**: -1. Read all three hook files. Identify the common pattern: load item via fetch → store in state → expose save function → handle abort controller cleanup. -2. Create `frontend/src/hooks/useConfigItem.ts` with a generic hook: - ```ts - function useConfigItem( - fetchFn: (signal: AbortSignal) => Promise, - saveFn: (data: T) => Promise - ): { data: T | null; loading: boolean; error: string | null; save: (data: T) => Promise } - ``` -3. Rewrite `useFilterConfig.ts`, `useActionConfig.ts`, and `useJailFileConfig.ts` to be thin wrappers around `useConfigItem` — each file should be <20 lines, just providing the specific fetch/save functions. -4. Run existing frontend tests: `cd frontend && npx vitest run` — all tests must pass. - -**Acceptance criteria**: `useConfigItem.ts` exists. The three original hooks use it and each reduced to <20 lines of domain-specific glue. - ---- - -### Task 12 — Standardise error handling in frontend hooks (✅ completed) - -**Priority**: Low -**Refactoring ref**: Refactoring.md §9 -**Affected files**: -- All hook files in `frontend/src/hooks/` that do fetch calls (at least: `useHistory.ts`, `useMapData.ts`, `useBans.ts`, `useBlocklist.ts`, and others) - -**What to do**: -1. Create a utility function in `frontend/src/utils/fetchError.ts`: - ```ts - export function handleFetchError(err: unknown, setError: (msg: string | null) => void): void { - if (err instanceof DOMException && err.name === "AbortError") return; - setError(err instanceof Error ? err.message : "Unknown error"); - } - ``` -2. Grep all hook files for `catch` blocks. In every hook that catches fetch errors: - - Replace the catch body with a call to `handleFetchError(err, setError)`. -3. Run existing frontend tests: `cd frontend && npx vitest run` — all tests must pass. - -**Acceptance criteria**: Every hook that fetches data uses `handleFetchError()` in its catch block. No hook surfaces `AbortError` to the UI. - ---- - -### Task 13 — Extract sub-components from large frontend pages (✅ completed) - -**Priority**: Low -**Refactoring ref**: Refactoring.md §11 -**Affected files**: -- `frontend/src/pages/BlocklistsPage.tsx` (~968 lines) -- `frontend/src/components/config/JailsTab.tsx` (~939 lines) -- `frontend/src/pages/JailsPage.tsx` (~691 lines) -- `frontend/src/pages/JailDetailPage.tsx` (~663 lines) - -**What to do**: -1. For each large file, identify logical UI sections that can be extracted into their own component files. -2. Suggested splits (adjust after reading the actual code): - - **BlocklistsPage.tsx**: Extract ``, ``, ``, ``. - - **JailsTab.tsx**: Extract ``, ``, ``, ``. - - **JailsPage.tsx**: Extract ``, ``. - - **JailDetailPage.tsx**: Extract logical sections (examine the JSX to identify). -3. Place extracted components in appropriate directories (e.g., `frontend/src/components/blocklist/`, `frontend/src/components/jail/`). -4. Each parent page should import and compose the new child components. Props should be passed down — avoid prop drilling deeper than 2 levels (use context if needed). -5. Run existing frontend tests: `cd frontend && npx vitest run` — all tests must pass. - -**Acceptance criteria**: No single page or component file exceeds ~400 lines. Each extracted component is in its own file. - ---- - -### Task 14 — Consolidate duplicated section/card styles (frontend) (✅ completed) - -**Priority**: Low -**Refactoring ref**: Refactoring.md §12 -**Affected files**: -- 13+ files across `frontend/src/pages/` and `frontend/src/components/` that define identical card/section styles using `makeStyles` with `backgroundColor`, `borderRadius`, `border`, `padding` using Fluent UI tokens. - -**What to do**: -1. Grep the frontend codebase for `makeStyles` calls that contain `backgroundColor` and `borderRadius` together. Identify the common pattern. -2. Create `frontend/src/theme/commonStyles.ts` with a shared `useCardStyles()` hook that exports the common section/card style class. -3. In each of the 13+ files, remove the local `makeStyles` definition for the card/section style and import `useCardStyles` from `commonStyles.ts` instead. Keep any file-specific style overrides local. -4. Run existing frontend tests: `cd frontend && npx vitest run` — all tests must pass. - -**Acceptance criteria**: A shared `useCardStyles()` exists in `frontend/src/theme/commonStyles.ts`. At least 10 files import it instead of defining their own card styles.
