The server maintains a separate JSON file cache to remember config values that were set during `create` and `update` operations. This cache is: +- Read on every `GET /api/providers` request +- Written on every `POST` (create) and `PUT` (update) that includes config values +- Cleaned up on `DELETE` +- Bootstrapped at server startup with a default for `nvidia-inference` + +--- + +## 11.

It obtains this from two sources: + +1. **Environment Variable:** `BREV_ENV_ID` (set by the Brev platform at container start) +2. **Host Header Detection:** Extracted from incoming request `Host` headers matching `\d+-(.+?)\.brevlab\.com` + +```python +def _extract_brev_id(host: str) -> str: + """Example: '80810-abcdef123.brevlab.com' → 'abcdef123'""" + match = re.match(r"\d+-(.+?)\.brevlab\.com", host) + return match.group(1) if match else "" +``` + +Detection is **idempotent** — once a Brev ID is detected from a Host header, it's cached globally and never overwritten. + +### URL Building + +``` +_build_openclaw_url(token): + If Brev ID available: + → https://80810-{brev_id}.brevlab.com/[?token=xxx] + Else: + → http://127.0.0.1:{PORT}/[?token=xxx] +``` + +**The URL points to the welcome-ui server itself** (port 8081 = `80810` in Brev URL format), NOT directly to port 18789. This is critical because: +- Brev's port-forwarding creates subdomains per port +- Cross-origin requests between Brev port subdomains are blocked +- By proxying through port 8081, the browser stays on one origin + +### Connection Details URL (for CLI users) + +``` +Gateway URL: + If Brev ID: https://8080-{brev_id}.brevlab.com + Else: http://{hostname}:8080 +``` + +This is a DIFFERENT port (8080) — the NemoClaw gateway itself, not the welcome-ui. + +--- + +## 14.

Gotchas, Edge Cases & Migration Warnings + +### 18.1 Proxy Mode Suppresses Default Headers + +When `_proxy_response = True`, the `end_headers()` method does NOT add CORS or Cache-Control headers. This flag is set to `True` before writing proxy response headers and reset to `False` in the `finally` block. If this is not handled correctly, proxy responses will get double headers. + +### 18.2 WebSocket Detection Before Route Matching + +WebSocket upgrade requests are checked BEFORE any API route. This means if a WebSocket upgrade request is sent to `/api/sandbox-status`, it will be proxied to the sandbox (if ready) instead of handled as an API call. This is intentional — the sandbox's OpenClaw UI uses WebSockets. + +### 18.3 Sandbox Ready Check Is Polled from Multiple Paths + +`_sandbox_ready()` is called: +1. In the routing function (to decide proxy vs. welcome-ui mode) +2. In `/api/sandbox-status` handler (with slightly different logic) +3. Both can trigger the `idle`/`creating` → `running` transition + +This means the sandbox can be detected as running even if `_run_sandbox_create` hasn't finished its own polling loop yet. + +### 18.4 No Body Parsing for OPTIONS + +OPTIONS requests return `204` immediately with CORS headers. No body parsing occurs. + +### 18.5 Config Cache Race Condition + +The provider config cache (`/tmp/nemoclaw-provider-config-cache.json`) has no file locking. Concurrent requests that modify different providers could overwrite each other's changes. In practice this is rare since provider CRUD is typically sequential. + +### 18.6 ANSI Stripping Is Critical + +All CLI output parsing MUST strip ANSI escape codes first. The `nemoclaw` CLI may use colored output even when stdout is a pipe. The regex used: +``` +\x1b\[[0-9;]*[a-zA-Z] +``` + +### 18.7 Policy Stripping Has Two Code Paths + +If PyYAML is not installed, the policy field stripping falls back to regex-based line stripping. The Node.js version should always use a YAML parser (like `js-yaml`) since it will be available in the Node ecosystem. + +### 18.8 Subprocess Environment + +The sandbox creation subprocess inherits the full environment (`os.environ.copy()`). No additional env vars are injected through the subprocess env — they're passed via the `-- env VAR=VAL` syntax in the command itself. + +### 18.9 The `--from` Flag Changed + +The code has a commented-out line: +```python +# "--from", NEMOCLAW_IMAGE, +``` +And uses instead: +```python +"--from", "nemoclaw", +``` +This means it uses a local sandbox name rather than a container image reference. + +### 18.10 Inject Key Hardcodes Provider Name + +The `_run_inject_key` function hardcodes `nvidia-inference` as the provider name. This is not configurable via the API. + +### 18.11 Error State Truncation + +When sandbox creation fails, only the last 2000 characters of the log are stored: +```python +_sandbox_state["error"] = f.read()[-2000:] +``` + +### 18.12 Static File Serving Falls Through to SimpleHTTPRequestHandler + +For non-API, non-index paths when the sandbox is NOT ready, Python's built-in `SimpleHTTPRequestHandler` serves files from the `ROOT` directory. This supports directory listing and MIME type detection. The Node.js equivalent would be `express.static()` or similar. + +### 18.13 Host Header Rewriting in Proxy + +Both HTTP and WebSocket proxies rewrite the `Host` header to `127.0.0.1:18789`. All other headers are forwarded as-is. This is critical because the upstream may validate the Host header. + +### 18.14 Connection Closure After Proxy + +Both HTTP and WebSocket proxy handlers set `self.close_connection = True`, forcing the connection closed after each proxied request. This prevents HTTP keep-alive from causing issues with the proxy. + +### 18.15 Process Group Isolation + +`start_new_session=True` on the sandbox creation Popen means the subprocess and all its children are in a separate process group. Sending SIGTERM to the server won't kill the sandbox creation process. + +### 18.16 Key Hash Is SHA-256 + +```python +hashlib.sha256(key.encode()).hexdigest() +``` + +The full hex digest is stored, but only the first 12 characters are logged for debugging. + +### 18.17 Log Streaming Gap for Node.js + +The Python server writes sandbox creation output to `/tmp/nemoclaw-sandbox-create.log` but does NOT stream it to the frontend. The frontend polls `/api/sandbox-status` every 3 seconds for status only. **For the Node.js version, you should add a log-streaming endpoint** (e.g., SSE or WebSocket on `/api/sandbox-logs`) that tails the log file in real-time. + +### 18.18 Temp File Cleanup Patterns + +- **Sandbox creation:** Temp policy file is cleaned up in the main flow after `proc.wait()`, but could be leaked if an exception occurs before that point. +- **Policy sync:** Temp file is cleaned up in a `finally` block — always cleaned up. + +The Node.js version should use `try/finally` or `process.on('exit')` to ensure cleanup. + +--- + +## 19.

Node.js should use `child_process.spawn()` with event-driven I/O. + +2. **Synchronous file reads in Python → async in Node.js:** Several functions (`_read_config_cache`, `_gateway_log_ready`, `_read_openclaw_token`) read files synchronously. In Node.js, use async versions to avoid blocking the event loop. + +3. **Global mutable state with locks → No locks needed in Node.js:** Since Node.js is single-threaded (event loop), you don't need locks for `_sandbox_state` and `_inject_key_state`. Simple objects work, but be careful with async operations that could interleave. + +4. **SimpleHTTPRequestHandler → Express static middleware:** Python's built-in static file handler supports directory listing and content-type detection. Ensure the Node.js equivalent handles the same MIME types. + +5. **subprocess.run() blocking → child_process.execFile() callback/promise:** All CLI calls in Python use blocking `subprocess.run()`. In Node.js, wrap `child_process.execFile()` in promises. + +6. **subprocess.Popen with streaming → child_process.spawn() with pipe:** The sandbox creation process uses line-by-line output streaming. In Node.js, `spawn()` gives you stdout/stderr as streams. + +7. **HTTP proxy reads full body → Node.js can stream:** The Python proxy reads the entire response body before forwarding. Node.js should pipe the response stream directly for better performance and to support log streaming. + +--- + +## Appendix A: Complete Request/Response Matrix + +| Method | Path | Status Codes | Auth | Body In | Body Out | +|--------|------|-------------|------|---------|----------| +| GET | `/api/sandbox-status` | 200 | No | None | JSON | +| POST | `/api/install-openclaw` | 200, 409 | No | None | JSON | +| POST | `/api/inject-key` | 200, 202, 400 | No | JSON | JSON | +| POST | `/api/policy-sync` | 200, 400, 502 | No | YAML text | JSON | +| GET | `/api/connection-details` | 200 | No | None | JSON | +| GET | `/api/providers` | 200, 502 | No | None | JSON | +| POST | `/api/providers` | 200, 400, 502 | No | JSON | JSON | +| PUT | `/api/providers/{name}` | 200, 400, 502 | No | JSON | JSON | +| DELETE | `/api/providers/{name}` | 200, 400, 502 | No | None | JSON | +| GET | `/api/cluster-inference` | 200, 400, 502 | No | None | JSON | +| POST | `/api/cluster-inference` | 200, 400, 502 | No | JSON | JSON | +| OPTIONS | any | 204 | No | None | None | +| GET/HEAD | `/`, `/index.html` | 200 | No | None | HTML | +| GET/HEAD | `/*.css`, `/*.js` | 200/404 | No | None | Static | +| * | any (sandbox ready) | varies | No | Proxied | Proxied | + +## Appendix B: Log Format Reference + +All server logging goes to `stderr` with prefixed tags: + +| Prefix | Source | +|--------|--------| +| `[welcome-ui]` | General server messages, proxy errors | +| `[sandbox]` | Lines from sandbox creation subprocess | +| `[inject-key HH:MM:SS]` | Key injection lifecycle | +| `[policy-sync HH:MM:SS]` | Policy sync lifecycle | + +Timestamps use `time.strftime("%H:%M:%S")` (local time, no date). diff --git a/brev/welcome-ui/__tests__/brev-detection.test.js b/brev/welcome-ui/__tests__/brev-detection.test.js new file mode 100644 index 0000000..2eb49f9 --- /dev/null +++ b/brev/welcome-ui/__tests__/brev-detection.test.js @@ -0,0 +1,76 @@ +// SPDX-FileCopyrightText: Copyright (c) 2025-2026 NVIDIA CORPORATION & AFFILIATES.
