## M0 CDP network spike
|
||||
|
||||
Run against the Clark binary declared by `clark-browser` 0.2.1:
|
||||
|
||||
```sh
|
||||
cd ../clark-browser
|
||||
python3 -m clarkbrowser fetch
|
||||
cd ../lume-ctrl
|
||||
M0_CDP_PORT=40746 M0_HTTP_PORT=40745 \
|
||||
CLARK_BINARY_PATH="$HOME/.clarkbrowser/chromium-148.0.7778.96/chrome" npm run spike
|
||||
npm test
|
||||
```
|
||||
|
||||
The two explicit loopback ports make the recorded run directly comparable; omit them to select free ports automatically, or change them if already occupied.
|
||||
|
||||
The spike starts only loopback listeners and uses generated, one-day self-signed TLS material in a temporary directory. Chromium accepts that local certificate with `--ignore-certificate-errors`; no proxy, CA installation, traffic interception, VNC, or external fixture is involved. `artifacts/m0-events.sample.jsonl` is the sanitized event output and `artifacts/m0-report.json` is the run result/resource snapshot.
|
||||
|
||||
### Connection and schema
|
||||
|
||||
Clark is launched directly with `--remote-debugging-address=127.0.0.1`. The runner waits on `/json/version`, discovers the startup page through `/json/list`, connects to its `webSocketDebuggerUrl`, and navigates to the already-listening loopback fixture before triggering test traffic. This avoids `clarkserve`'s current `0.0.0.0` default; a protected gateway and short-lived credentials remain required outside a local Spike.
|
||||
|
||||
Every JSONL line has `schema_version`, `session_id`, `target_id`, and `kind`. HTTP records use `request_id`; WebSocket records use the CDP `requestId` as `connection_id`. Kind-specific fields are nested under `request`, `response`, `headers`, `body`, or `error`. Query strings are removed, sensitive headers are replaced by `[REDACTED]`, and WebSocket payloads are never persisted. Response bodies are safe by default: a fetched body is recorded as `{state:"fetched",storage:"omitted",reason:"default_body_policy",bytes:N}` with no content; oversize and unavailable bodies retain distinct structured states.
|
||||
|
||||
### Coverage and limits
|
||||
|
||||
| Case | Clark 0.2.1 / Chromium 148.0.7778.96 | Evidence or limit |
|
||||
| --- | --- | --- |
|
||||
| HTTP request → response → finished | Pass | Same `request_id` asserted for `/ok`, `/large`, and `/secure`. |
|
||||
| Failed HTTP request | Pass | Unused loopback port produces `loadingFailed`; error text retained. |
|
||||
| HTTPS without MITM | Pass | Direct browser connection to local TLS fixture; no network intermediary. |
|
||||
| WebSocket lifecycle and frames | Pass | Created, handshake, sent, received, and closed share one `connection_id`; payload omitted. |
|
||||
| `getResponseBody` success | Pass | Called after `loadingFinished`; fetched bytes are recorded but content is omitted by default. |
|
||||
| Sensitive response body | Pass | Random secret fixture is fetched; serialized JSONL is asserted not to contain its value. |
|
||||
| Body size limit | Pass | 2 KiB fixture is reported as `size_limit` and not persisted with the 1 KiB default. |
|
||||
| Body unavailable | Pass | Calling on the failed request returns the original CDP error as structured `cdp_error`. |
|
||||
| Target close | Pass | Target connection closes; browser process remains alive. |
|
||||
| CDP disconnect/reconnect | Pass | Browser-side target close triggers the real socket `close` callback; the browser stays alive and a new target accepts a verified CDP command. |
|
||||
| Cookie / Authorization / Set-Cookie | Pass | `Network.*ExtraInfo` values are redacted before JSONL serialization. |
|
||||
| Cache-specific body availability | Not covered | Cache behavior varies by response/cache mode; retain optional-body semantics in M1. |
|
||||
| Sustained high-rate WebSocket | Not covered | M0 stores metadata only; add frame/event caps before M1 load testing. |
|
||||
| Multi-target/session isolation | Not covered | Explicitly M1 scope. |
|
||||
| Startup `Page.navigate` | Intermittent | This build can report `Inspector.detached: Render process gone`; the exact startup failure is bounded and recorded. |
|
||||
|
||||
The resource numbers are a one-time `ps` snapshot of the browser process tree, not a benchmark. Repeat under the intended container limits before setting capacity targets.
|
||||
|
||||
The runner restarts Clark at most three times only from the local startup navigation/readiness block, and only after CDP reports the exact detached reason `Render process gone.`. Every failed attempt is retained in `attempt_failures`; a timeout without that reason and every post-startup error fail immediately with the original message.
