enricobuehler 0868b6a364 fix(vdisplay): compositor availability follows the live session, not the env
GNOME/Mutter reported "Unavailable" on a host sitting in a live Mutter
session — and, on the same request, "Default", because the two columns had
different sources. available() asked each backend, and those probes read
the process env (XDG_CURRENT_DESKTOP for Mutter, WAYLAND_DISPLAY for
KWin's registry handshake, SWAYSOCK for sway) — env a host started outside
the session (systemd --user, a TTY, ssh) never inherited. It is only
retargeted at the live session on the connect path, so the answer also
flipped depending on whether anyone had connected yet.

Both columns now come from the same /proc scan detect() already used: the
live session's compositor is usable by definition, as is an explicit
operator pin, and the per-backend probe stays as the fallback for backends
that are not the live session (gamescope, which spawns its own). A live
KWin without the zkde_screencast grant now surfaces as available and fails
at create with that probe's precise message, which beats "no usable
compositor" on a box visibly running KDE.

Mutter's env sniff stays deliberately narrow — one var, not three.
XDG_CURRENT_DESKTOP is the one apply_session_env owns end to end (written
per connect, scrubbed when nothing is live); sniffing DESKTOP_SESSION
alongside would resurrect the bug that scrub exists to prevent, where a
stale value after a gnome-shell crash routes the next client into a dead
session.

Non-Linux hosts now report no compositors at all rather than five Linux
backends flagged unavailable with no default — on Windows the pf-vdisplay
driver is the only backend and vdisplay::open ignores the argument, so the
old list read as broken detection instead of "not applicable here". The
console says so explicitly.

punktfunk web — management console

The browser UI for the punktfunk host's management REST API (crates/punktfunk-host/src/mgmt.rs, OpenAPI at api/openapi.json). It shows live status, host capabilities, paired clients, the pairing-PIN flow, and session controls.

Stack: TanStack Start (full SSR) on Bun via Nitro v2 (bun preset) · React Query through orval codegen from the OpenAPI spec · @unom/ui — the shared punktfunk/unom design system the marketing site + docs are built on (Tailwind v4, animated components on the violet brand over dark chrome) · Paraglide i18n (en/de). Package manager + runtime: Bun.

The @unom registry mapping lives in .npmrc; the auth token comes from ~/.npmrc (or a CI secret).

Develop

# from web/  — Bun is the toolchain (https://bun.sh)
bun install               # runs `prepare` → codegen (orval + paraglide)
bun run dev               # http://localhost:47992

# The dev server proxies /api → https://127.0.0.1:47990 (the host's mgmt API; it serves HTTPS
# with the host's self-signed identity cert — the dev proxy uses `secure: false`).
# Point it elsewhere: PUNKTFUNK_MGMT_URL=https://<host>:47990 bun run dev

Start a host with the management API up:

# from the repo root — `serve` brings up the native punktfunk/1 plane + the mgmt API (the console
# only needs the mgmt API; add --gamestream too if you also want the Moonlight surface):
WAYLAND_DISPLAY=wayland-kde XDG_CURRENT_DESKTOP=KDE \
  cargo run -rp punktfunk-host -- serve
# loopback :47990, no token (a token is mandatory for non-loopback binds).

If the host runs with --mgmt-token, set it under Settings → API token (stored in localStorage, sent as Authorization: Bearer … by the orval fetcher).

Build & run (Nitro + Bun)

The console runs on bun (Bun.serve is a Bun API — node can't run it): Nitro's bun preset plus a custom entry (nitro-entry/bun-https.mjs) that calls Bun.serve({ tls }), so it serves HTTPS (HTTP/1.1 over TLS) with the host's own identity cert (the cert native clients already pin). One trust anchor across the data plane, the mgmt API, and this console. (No HTTP/2 — Bun.serve has no h2 server — and no HTTP/3, which a browser won't speak against this self-signed, no-SAN host cert; a browser-trusted, SAN-matching cert + a fronting server would be needed, out of scope for a LAN console.)

bun run build             # → .output/  (Nitro `bun` preset + our Bun.serve TLS entry)
PORT=47992 HOST=0.0.0.0 \
  PUNKTFUNK_UI_PASSWORD=PUNKTFUNK_MGMT_TOKEN=\
  PUNKTFUNK_MGMT_URL=https://127.0.0.1:47990 \
  PUNKTFUNK_UI_TLS_CERT=~/.config/punktfunk/cert.pem \
  PUNKTFUNK_UI_TLS_KEY=~/.config/punktfunk/key.pem PUNKTFUNK_UI_SECURE=1 \
  bun run start           # = bun run .output/server/index.mjs
# PUNKTFUNK_UI_TLS_* unset ⇒ plain HTTP (local dev); both set ⇒ HTTPS (HTTP/1.1 over TLS).
# The host's self-signed mgmt cert is accepted only for the proxy's loopback hop, scoped in code
# (Bun per-request TLS: server/routes/api/[...].ts) — no process-wide NODE_TLS_REJECT_UNAUTHORIZED.
# See .env.example.
bun run lint              # tsc --noEmit

The built Nitro bun server SSR-renders the app and is the only thing exposed on the LAN. Run it on the same box as the host; it serves the console over HTTPS on :47992 (or $PORT).

Auth (backend-for-frontend)

Single-user, login-gated. Config via env (see .env.example):

  • The console requires a login (PUNKTFUNK_UI_PASSWORD). On success the server sets a sealed session cookie (h3 useSession, AES-GCM). server/middleware/auth.ts gates every request — pages redirect to /login, /api returns 401 — and fails closed (503) if PUNKTFUNK_UI_PASSWORD is unset, so a misconfigured LAN server admits no one.
  • The bearer-token admin surface of the management API is loopback-only — the host honors a bearer token only from a loopback peer, so the admin API is never LAN-exposed. The web server holds PUNKTFUNK_MGMT_TOKEN server-side and injects it when proxying /api/**PUNKTFUNK_MGMT_URL (loopback; server/routes/api/[...].ts). The token never reaches the browser; the browser only ever holds the session cookie. (The host also binds the read-only surface — host status + the game library — to the LAN so paired native clients can fetch it directly over mTLS; that path uses client certs, not the token, and never touches this console.)

So: browser ──password──▶ web server (session cookie) ──mgmt token, server-side──▶ mgmt API. Run the host with a matching token: cargo run -rp punktfunk-host -- serve + PUNKTFUNK_MGMT_TOKEN=… (or --mgmt-token …). vite dev has no gate (localhost-only) and proxies straight to the loopback mgmt API.

Toolchain notes (load-bearing): TanStack Start's start-plugin-core peer-requires Vite ≥ 7 — on Vite 6 the build's prerender/post-build hook silently doesn't run. @vitejs/plugin-react must match Vite (v5 ↔ Vite 7, v6 ↔ Vite 8); it's required even for dev (TanStack Start's dev mode needs the React Refresh runtime, else a blank screen). Nitro is the server target — without it vite build only emits client+SSR bundles, no deployable server. The Nitro bun preset makes .output/server/index.mjs Bun-runnable.

Codegen

Generated code is not committed (gitignored) — reproduced from sources:

  • bun run codegen — regenerate the API client (orval) + i18n runtime (paraglide). Runs on bun install (prepare) and before dev/build (pre* for orval; the Vite plugin compiles paraglide on dev/build).
  • After a management-API change, regenerate the spec on the Rust side first: cargo run -p punktfunk-host -- openapi > api/openapi.json, then bun run api:gen.
