Goal + +Four small refinements called out by the reviewer: + +1. Add a typed REST endpoint that returns the authoritative `EventStatePayload` (a one-shot snapshot) and call it from `challenges.page.ts` before/alongside `wireSse` so the page has state synchronously even if the SSE stream hasn't delivered its first frame yet. +2. In `challenges.store.ts`, stop double-dispatching SSE frames: register only the named `'solve'` listener (plus a one-time `'message'` listener for backward compat with `EventStatusStore` which still uses `'message'`). Move the `applyStatusPayload` call out of the store and back into the page's status wiring, since the status SSE is the responsibility of `EventStatusStore`, not the challenges store. +3. In `backend/src/modules/challenges/challenges.service.ts`, remove the two `publishSolveEvent(...)` calls that fire on `already_solved` (existing-row branch and unique-constraint recovery branch). Only the fresh-insert branch (currently line 414) should publish — duplicate broadcasts are noise since the row is unchanged. +4. Add a small functional REST error interceptor (`HttpInterceptorFn`) that pipes 4xx/5xx responses into a `NotificationService.error(...)` call so the modal/grid can surface failure state without bespoke try/catch everywhere. Register it in `frontend/src/main.ts`. + +## 1. Architectural Reconnaissance + +- **Backend controller surface for events**: `backend/src/modules/challenges/events.controller.ts` exposes `GET /api/v1/events` (SSE) and `backend/src/modules/system/system.controller.ts` exposes `GET /api/v1/events/status` (legacy SSE, plural-segmented) and a public `GET /api/v1/event/status` snapshot. There is no plain JSON REST snapshot for the event window under `/api/v1/challenges`. The new endpoint will live next to the challenges controller (`ChallengesController`). +- **DTO**: `EventStatusService.getState()` returns `EventStatePayload` which matches the snake_case status shape (`serverNowUtc`, `eventStartUtc`, `eventEndUtc`, `secondsToStart`, `secondsToEnd`). We reuse it. +- **Frontend SSE wiring today**: `ChallengesStore.wireSse` registers the same handler for `'message'`, `'solve'`, `'status'`. Because the backend SSE is well-formed (`event: solve` / `event: status`), the dispatcher in `AuthenticatedEventSourceService.parseAndDispatch` fires both `'message'` AND the named event — so the store's handler runs twice per frame. Fix: the challenges store only needs `'solve'` (to update cards + notify modal listeners); the `'status'` frame is consumed by `EventStatusStore` via its existing `'message'` listener (we'll keep that). +- **`EventStatusStore` SSE wiring**: it still uses `addEventListener('message', ...)` and ignores named events. That's correct for backward compat — it doesn't double-process frames. +- **REST error notification**: the app currently has no toast/notification service. We'll add a minimal `NotificationService` with an `error(message)` method that logs to console in non-browser contexts and a small DOM-mountable component is out of scope; the interceptor calls it and any future toast UI can subscribe to its signal. +- **Interceptors run in registration order on the request and reverse order on the response** (`withInterceptors([a, b])` → request runs a→b, response runs b→a). For a pure error inspector that wants to act on every response regardless of what auth/csrf did, we register it AFTER `authInterceptor` so it sees the final response on the way out. + +## 2. Impacted Files + +### Backend — To Modify +- `backend/src/modules/challenges/challenges.controller.ts` — add `@Get('status')` returning `EventStatePayload`. +- `backend/src/modules/challenges/challenges.service.ts` — remove two `publishSolveEvent(...)` calls in the existing-row branch and the constraint-recovery branch; keep the one in the fresh-insert branch. + +### Frontend — To Create +- `frontend/src/app/core/services/notification.service.ts` — minimal signal-based notification store with `error(message)`, `info(message)`, and a `messages` signal. +- `frontend/src/app/core/interceptors/error-notification.interceptor.ts` — `HttpInterceptorFn` that maps non-2xx responses to `NotificationService.error(...)`. + +### Frontend — To Modify +- `frontend/src/app/features/challenges/challenges.service.ts` — add `getEventState()` returning `Observable`. +- `frontend/src/app/features/challenges/challenges.store.ts` — expose `applyStatus(payload)` (already exists), change `wireSse` to register ONLY `'solve'` (drop `'message'` and `'status'` listeners in this store). Move the local handler logic so it doesn't process status frames. +- `frontend/src/app/features/challenges/challenges.page.ts` — call `store.getEventState()` once at boot (before `wireSse`) and pass the result to `eventStatus.applyServerStatus(payload)`; update `wireSse` listener if needed (no change required for status, since `EventStatusStore` handles it). +- `frontend/src/main.ts` — register `errorNotificationInterceptor` AFTER `authInterceptor`. + +### Tests — To Modify +- `tests/backend/challenges-submit-flag.spec.ts` — change the SSE-solve-payload test to subscribe once after a fresh insert; assert that two consecutive correct submissions yield ONE `emitScoreboard` call, not two. +- `tests/frontend/event-status.store.spec.ts` — add a small assertion that `currentServerTimeUtc` returns a valid ISO string and that `reloadAtCountdownZero` fires exactly once. +- New test file `tests/frontend/notification-interceptor.spec.ts` — assert the interceptor calls `NotificationService.error(...)` on a 500 response and does NOT call it on a 2xx response. + +## 3. Proposed Changes + +### Backend + +1. **`challenges.controller.ts`** — add (after the existing `board`/`detail`/`submit` handlers): + ```ts + @Get('status') + @ApiOperation({ summary: 'Authenticated event-window snapshot (REST JSON)' }) + async eventState(): Promise { + return this.statusSvc.getState(); + } + ``` + Inject `EventStatusService` into the controller (add to constructor). The existing `getState()` already returns `EventStatePayload`. This endpoint sits at `/api/v1/challenges/status`. We avoid `events/status` to not collide with the existing legacy SSE route. + +2. **`challenges.service.ts`** — remove the `publishSolveEvent(...)` call at line 294 (existing-row branch) and the one at line 368 (unique-constraint recovery branch). Keep only the line 414 call (fresh-insert path). The `publishSolveEvent` helper itself stays (it's still called from the fresh-insert path). + +### Frontend + +1. **`notification.service.ts`** (new): + ```ts + import { Injectable, signal } from '@angular/core'; + export interface Notification { id: number; kind: 'error' | 'info'; message: string; ts: number; } + @Injectable({ providedIn: 'root' }) + export class NotificationService { + private next = 1; + readonly messages = signal([]); + error(message: string): void { + this.push('error', message); + // eslint-disable-next-line no-console + console.error('[notification]', message); + } + info(message: string): void { + this.push('info', message); + // eslint-disable-next-line no-console + console.info('[notification]', message); + } + dismiss(id: number): void { + this.messages.update((cur) => cur.filter((m) => m.id !== id)); + } + private push(kind: Notification['kind'], message: string): void { + const n: Notification = { id: this.next++, kind, message, ts: Date.now() }; + this.messages.update((cur) => [...cur, n]); + } + } + ``` + +2. **`error-notification.interceptor.ts`** (new): + ```ts + import { HttpErrorResponse, HttpInterceptorFn } from '@angular/common/http'; + import { inject } from '@angular/core'; + import { catchError, throwError } from 'rxjs'; + import { NotificationService } from '../services/notification.service'; + function friendlyMessage(status: number, body: any): string { + const code = body?.code as string | undefined; + const msg = (body?.message as string | undefined) ?? ''; + if (code === 'EVENT_NOT_RUNNING') return 'Submissions are only accepted while the event is running.'; + if (code === 'FLAG_INCORRECT') return 'Incorrect flag.'; + if (status === 0) return 'Network error. Please try again.'; + if (status === 401 || status === 403) return 'Your session is no longer valid.'; + if (status >= 500) return 'Server error. Please try again later.'; + return msg || `Request failed (${status}).`; + } + export const errorNotificationInterceptor: HttpInterceptorFn = (req, next) => { + const notify = inject(NotificationService); + return next(req).pipe( + catchError((err) => { + if (err instanceof HttpErrorResponse) { + notify.error(friendlyMessage(err.status, err.error)); + } else { + notify.error('Unexpected error.'); + } + return throwError(() => err); + }), + ); + }; + ``` + +3. **`challenges.service.ts`** — add: + ```ts + getEventState(): Observable { + return this.http + .get('/api/v1/challenges/status', { withCredentials: true }) + .pipe(catchError((err) => throwError(() => toEnvelope(err)))); + } + ``` + Add `EventStatePayload` to the import from `./challenges.pure`. + +4. **`challenges.store.ts`** — update `wireSse` to register only `'solve'`: + ```ts + const handler = (ev: MessageEvent | Event) => this.handleSseFrame(ev); + src.addEventListener('solve', handler); + ``` + Drop the `addEventListener('message', ...)` and `addEventListener('status', ...)` calls inside `wireSse`. `handleSseFrame` already short-circuits non-`'solve'` events by virtue of the `me.type === 'solve'` check at the top, so no further change needed inside that method. + +5. **`challenges.page.ts`** — at `ngOnInit`, before wiring the SSE: + ```ts + // REST snapshot first so the page has synchronous state. + this.store.getEventState().subscribe({ + next: (payload) => this.eventStatus.applyServerStatus(payload), + error: () => undefined, // SSE will deliver the next frame; don't notify. + }); + ``` + No structural change to `wireSse` — the challenges store now only listens for `'solve'`; `EventStatusStore` continues to listen for `'message'` on the same source (which the transport dispatches in addition to `'solve'`). + +6. **`main.ts`** — register the error interceptor last so it sees the final response: + ```ts + provideHttpClient(withInterceptors([csrfInterceptor, authInterceptor, errorNotificationInterceptor])), + ``` + +## 4. Test Strategy + +- **Backend** (`tests/backend/challenges-submit-flag.spec.ts`): change the SSE-payload test to subscribe ONCE on `hub.scoreboard$()` and assert that two consecutive correct submissions (with an artificial constraint-recovery path forced via the existing concurrency test) emit only ONE payload. Add a new test that asserts `GET /api/v1/challenges/status` returns the running state with `server_now_utc` + `event_start_utc` + `event_end_utc` + `seconds_to_start` + `seconds_to_end` for an authenticated user. +- **Frontend** (`tests/frontend/event-status.store.spec.ts`): add `applyServerStatus` once, advance the tick, assert `currentServerTimeUtc()` is a valid ISO string and that `reloadAtCountdownZero` fires exactly once (not twice on consecutive ticks where `secondsToStart` is still 0). +- **Frontend** (`tests/frontend/notification-interceptor.spec.ts`, new): create an `HttpClient` via `provideHttpClient(withInterceptors([errorNotificationInterceptor]))` and a fake backend that returns 200 for one URL and 500 for another; assert `NotificationService.messages()` only contains the 500 message. +- All existing 504 tests must continue to pass. + +## 5. Notes / Trade-offs + +- We use a plain REST snapshot instead of "best-authenticated equivalent" of the public `/api/v1/event/status` because the public endpoint is unauthenticated and returns a slightly different shape (legacy `status` field, no `state` enum, only `countdownMs`). The new authenticated snapshot uses the canonical `EventStatePayload` shape and is reused by both the page bootstrap and (later) any admin tooling. +- The error interceptor only fires for HTTP errors thrown by Angular's `HttpClient`. The `ChallengesApiService` wraps these in its own `toEnvelope()` and re-throws, so the interceptor sees `HttpErrorResponse` and the service's catchError re-emits the envelope. We do not double-notify. +- Removing the two `publishSolveEvent` calls is safe because the fresh-insert path (line 414) is the only one that mutates state — the existing-row and constraint-recovery branches do not insert a new row, so emitting a "new solve" SSE frame for them is misleading to other connected clients (who would re-render an unchanged row). diff --git a/.kilo/plans/903.md b/.kilo/plans/903.md deleted file mode 100644 index 2619898..0000000 --- a/.kilo/plans/903.md +++ /dev/null @@ -1,94 +0,0 @@ -# Implementation Plan: Job 903 — Admin Challenges Import must Replace, Modal must Auto-Close - -## 1.

Re-link the now-unreferenced disk files for unlink and unlink any orphaned file rows after the swap. - - `frontend/src/app/features/admin/challenges/challenges.component.ts` — after a successful confirmed import (`onImportConfirm`), call `closeImport()` so the dialog disappears (it currently stays open showing the result message and a manual Close button). - - `docs/guides/admin-challenges.md` — clarify that **Import with `?confirm=overwrite` replaces the entire challenge set** (not just upserts by name).

Proposed Changes - -### 3.1 Backend — `AdminChallengesService.importConfirmed` becomes a full replace - -In `backend/src/modules/admin/challenges.service.ts`, refactor `importConfirmed` (currently lines 412–522) so the confirmed path: - -1. **Stage every file up front** (unchanged logic, lines 421–446). Keep the early `rollbackStaged` on validation failure. -2. **Inside one transaction** (unchanged transaction wrapper, line 450): - a. Load every existing challenge row with `manager.getRepository(ChallengeEntity).find()` (no filter). - b. Capture each existing challenge's `ChallengeFileEntity` rows (`find({ where: { challengeId: In(ids) } })`) so we know which `storedFilename`s are still referenced after the transaction. - c. Delete every existing challenge row with a single `manager.delete(ChallengeEntity, {})` — TypeORM cascades to `challenge_file` and `solve` rows via the existing FK cascade. This is the **replace** semantics. - d. Then iterate `doc.challenges` and (as today) skip entries whose category is unknown, otherwise create a new challenge row + new file rows pointing at the already-staged tokens. Result counts stay `{ imported, skipped, warnings }`. -3. **After commit, clean up disk** — for the captured pre-existing stored filenames, call `fileService.removeFinal(storedFilename)` best-effort (same helper used by `remove()`). Newly-inserted challenges' files are then committed via the existing `commit(item.staged.token)` loop (lines 506–517). -4. **Do not break the preview path.** `previewImport` keeps the existing conflict/unknown-category logic; the destructive replace only happens when `?confirm=overwrite` (controller path `admin-challenges.controller.ts:87-92`). -5. **No changes to DTOs or to the export shape.** `exportAll()` already produces the versioned envelope that the new behavior requires for round-tripping. - -**Edge cases to handle explicitly:** -- Empty `doc.challenges` ⇒ result `{ imported: 0, skipped: [], warnings: [] }`; existing rows are wiped, files unlinked, no new rows created. -- Unknown-category rows ⇒ counted in `skipped`; do **not** preserve them, do **not** abort the wipe.

The result branch is kept as a defensive fallback for any future flow that intentionally keeps the modal open (e.g. partial-failure display). - -### 3.3 Docs — clarify the replace semantics - -- `docs/guides/admin-challenges.md` — under the "Import" section (line 103) replace the third bullet ("Click Overwrite & Import … the server upserts challenges inside one transaction by case-insensitive name") with: "Click **Overwrite & Import** → the client posts the same document with `?confirm=overwrite`. The server stages every file up front (rolling back any FS failure), then **wipes every existing challenge (cascade-deleting their `challenge_file` and `solve` rows and best-effort unlinking their disk files) and inserts the archive's challenges** in one transaction." -- Update the last "Notes" line on idempotency (line 138) to: "Importing the same document twice is idempotent: every existing challenge (matching or not) is replaced by the archive contents." -- `docs/architecture/key-files.md` — update the `challenges.service.ts` responsibility to "... CRUD, list aggregates, transactional deletion, export, full-replace import orchestration." - -## 4. Test Strategy - -### 4.1 Backend contract test — `tests/backend/admin-challenges-import-replace.spec.ts` - -- Mirror the wiring of `tests/backend/admin-challenges-import-export.spec.ts`: `:memory:` SQLite, unique `mkdtempSync(os.tmpdir() + '/hipctf-challenges-import-replace-…')` `UPLOAD_DIR`, all migrations including `UpgradeChallengeAdminSchema1700000000500`, TypeOrmModule.forFeature for `CategoryEntity`, `ChallengeEntity`, `ChallengeFileEntity`, `SolveEntity`. -- AAA structure. Mocking strategy: no external boundaries — use real in-memory SQLite + real `ChallengeFilesService` writing to the temp dir. Isolation: per-file temp dir (no parallel FS races). -- Tests (minimal, one logical assertion each): - 1. **Replace wipes unrelated challenges** — Seed `Alpha` (CRY, NC, port=1337, flag='flag{a}', with one staged file committed) and `Bravo` (CRY, WEB). Call `importConfirmed` with a single-challenge doc `{ name: 'Imported Charlie', … categorySystemKey: 'CRY', … }`. Assert `list({}).map(r => r.name)` is exactly `['Imported Charlie']` and that `chRepo.count()` equals 1. - 2. **Disk files of wiped challenges are unlinked** — Capture the stored filename of Alpha's committed file via `fileRepo.findOne({ where: { challengeId: alpha.id } })`. After the import, assert `fs.existsSync(path.join(finalDir, alphaStoredName))` is `false`, while the new challenge's stored file exists. - 3. **Empty archive wipes everything** — Re-seed Alpha, then `importConfirmed` with `{ challenges: [] }`. Assert `chRepo.count() === 0` and the previously-committed disk file is unlinked. - 4. **Unknown-category rows are skipped, not preserved** — Seed `Keep` (WEB). Import a doc containing one unknown-category challenge plus nothing else. Assert `result.skipped` has length 1 and `list({})` is empty (the wipe still happened). - -### 4.2 Frontend modal test — `tests/frontend/admin-challenges-import-autoclose.spec.ts` - -- Smart container test using `TestBed.createComponent(AdminChallengesComponent)` to exercise the live handler. -- Mock `AdminService` (`jest.fn()` for `previewChallengeImport`, `confirmChallengeImport`, `listChallenges`, `listCategories`, `exportChallenges`) and stub the document `createElement('input')` file-picker flow by setting `importDoc`/`importPreview` directly via a small helper (or by calling the public `openImport()` + injecting the file via a fake `` ref). Keep it minimal: directly drive the component signals is preferable to mocking the file picker. -- AAA structure. Mocking strategy: only `AdminService` (network boundary). No DOM snapshotting; we assert on signal values (OnPush friendly) and DOM text via `fixture.nativeElement.textContent` if needed. -- Tests: - 1. **`onImportConfirm` closes the modal after success** — arrange: `component.importOpen.set(true)`, `component.importDoc.set({ … })`, `component.importPreview.set({ total: 1, conflicts: [], unknownCategories: [], warnings: [] })`. Stub `admin.confirmChallengeImport` to resolve `{ imported: 1, skipped: [], warnings: [] }` and `admin.listChallenges` to resolve `[]`. Act: `await component.onImportConfirm()`.
