Adds ConnectScreen (shown before Login in Tauri when no backend is saved), backed by tauri-plugin-store persisting the operator-entered URL across restarts. CSP's connect-src tightens to 'self' only — all backend traffic already routes through tauri-plugin-http/websocket, which run Rust-side and are outside connect-src's reach anyway — and the real access boundary moves to capabilities/default.json's http:default scope, wildcarded so an operator-chosen host is actually reachable. Adds a "Change server" control in Setup (desktop-only) to repoint an already-configured install. While tracing the desktop auth path for this: tauri-plugin-http's fetch() runs through Rust's reqwest, which keeps its own cookie jar separate from the webview, so document.cookie on tauri://localhost never sees the parking_csrf cookie the server sets (open upstream bug, tauri-apps/tauri#13045/#11518). This means the desktop app has likely been silently sending no CSRF header on every mutation since the shell was first built — pre-existing, independent of this change. Fixed by having sessionView() (routes/auth.ts) also echo the CSRF value in the login/me JSON body; the desktop client stashes it in memory and echoes that instead of reading document.cookie. assertCsrf() itself is untouched. Verified end-to-end against a real LAN-bound dev server: login returns a csrfToken matching the cookie, a mutation using the body-sourced token in X-CSRF-Token succeeds (200), and the same mutation without it still correctly 403s. --- apps/desktop/src-tauri/Cargo.lock | 29 +++++ apps/desktop/src-tauri/Cargo.toml | 4 + .../src-tauri/capabilities/default.json | 8 +- apps/desktop/src-tauri/src/lib.rs | 16 ++- apps/desktop/src-tauri/tauri.conf.json | 4 +- apps/server/src/routes/auth.ts | 24 +++- apps/web/package.json | 1 + apps/web/src/App.tsx | 36 +++++- apps/web/src/ConnectScreen.tsx | 116 ++++++++++++++++++ apps/web/src/api.ts | 53 ++++++-- apps/web/src/lib/backend-config.ts | 88 +++++++++++++ apps/web/src/lib/desktop-updater.ts | 6 +- apps/web/src/lib/i18n/en.ts | 14 +++ apps/web/src/lib/i18n/sq.ts | 14 +++ apps/web/src/lib/origin.ts | 43 +++++-- apps/web/src/lib/platform-ws.ts | 7 +- apps/web/src/lib/tauri-env.ts | 6 + apps/web/src/router.tsx | 50 ++++++++ pnpm-lock.yaml | 10 ++ wiki/decisions/desktop-shell-tauri.md | 69 ++++++++++- wiki/log.md | 24 ++++ 21 files changed, 575 insertions(+), 47 deletions(-) create mode 100644 apps/web/src/ConnectScreen.tsx create mode 100644 apps/web/src/lib/backend-config.ts create mode 100644 apps/web/src/lib/tauri-env.ts diff --git a/apps/desktop/src-tauri/Cargo.lock b/apps/desktop/src-tauri/Cargo.lock index c554d90..bb76ad1 100644 --- a/apps/desktop/src-tauri/Cargo.lock +++ b/apps/desktop/src-tauri/Cargo.lock @@ -2305,6 +2305,7 @@ dependencies = [ "tauri-build", "tauri-plugin-http", "tauri-plugin-process", + "tauri-plugin-store", "tauri-plugin-updater", "tauri-plugin-websocket", ] @@ -3793,6 +3794,22 @@ dependencies = [ "tauri-plugin", ] +[[package]] +name = "tauri-plugin-store" +version = "2.4.4" +source = "registry+https://github.com/rust-lang/crates.io-index" +checksum = "6708afbe549f176b712066e71648ba8fafba20789453718260c7ca356733cb0c" +dependencies = [ + "dunce", + "serde", + "serde_json", + "tauri", + "tauri-plugin", + "thiserror 2.0.18", + "tokio", + "tracing", +] + [[package]] name = "tauri-plugin-updater" version = "2.10.1" @@ -4301,9 +4318,21 @@ source = "registry+https://github.com/rust-lang/crates.io-index" checksum = "63e71662fa4b2a2c3a26f570f037eb95bb1f85397f3cd8076caed2f026a6d100" dependencies = [ "pin-project-lite", + "tracing-attributes", "tracing-core", ] +[[package]] +name = "tracing-attributes" +version = "0.1.31" +source = "registry+https://github.com/rust-lang/crates.io-index" +checksum = "7490cfa5ec963746568740651ac6781f701c9c5ea257c58e057f3ba8cf69e8da" +dependencies = [ + "proc-macro2", + "quote", + "syn 2.0.118", +] + [[package]] name = "tracing-core" version = "0.1.36" diff --git a/apps/desktop/src-tauri/Cargo.toml b/apps/desktop/src-tauri/Cargo.toml index 1012772..c23b6d8 100644 --- a/apps/desktop/src-tauri/Cargo.toml +++ b/apps/desktop/src-tauri/Cargo.toml @@ -33,6 +33,10 @@ tauri-plugin-http = "2" # (ws://127.0.0.1:3000 from the secure tauri://localhost origin) — HTTP and WS # are separate browser checks, so this needs its own plugin. tauri-plugin-websocket = "2" +# Persists the operator-configured backend URL (host:port of the Fastify +# server this install talks to) across restarts.

The second, req.jwtVerify(), reads the HttpOnly cookie — which tauri-plugin-websocket (a bare tungstenite client, no cookie jar) can never send. Every desktop handshake 401'd and use-live-feed reconnected every 10s (confirmed in the park-2 server log). - routes/ws.ts: POST /api/ws/ticket (cookie + CSRF auth) mints a 30s, single-use, in-memory ticket; the WS preHandler accepts it via an x-ws-ticket header after the Origin check, then the same report:read role check. Browser cookie path unchanged; JWT stays out of JS. - platform-ws.ts: fetch a ticket before connect, send it with the Origin header; connect failures now go through logClient (rate-limited). - logger.ts: flush read the CSRF token from document.cookie, null on desktop, so every desktop POST /api/logs 403'd and was dropped silently — no desktop client log had ever reached app_logs. Stash moved to a dependency-free lib/desktop-csrf.ts shared by api.ts and logger.ts. - backend-config.ts: ConnectScreen probe uses the unauthenticated /health (now also returns app: "parking-system") instead of accepting any 401. - README: local-AppImage release gate — tauri dev runs at http://localhost:5173, not tauri://localhost, so none of these origin-dependent bugs reproduce there. - wiki: new section + log entry; four citation corrections. Requires the server image with this commit deployed before the new desktop build connects (the ticket endpoint must exist).
