fix(site): OpenCLI on Windows and a run timeout - #408
Conversation
📝 WalkthroughWalkthroughOpenCLI now selects the npm executable for the current platform and applies a configurable runtime limit to commands. It monitors the Node process while reading stdout concurrently, and removes the request file when spawning fails or a timeout occurs. ChangesOpenCLI command execution

DEFAULT_TIMEOUT_SECS when no override is present.
- Line 80: Update the timeout calculation around Duration::from_secs so an
explicitly set environment override is used as the effective limit, even when it
is shorter than the declared timeout; when no override is set, preserve the
existing default-versus-declared timeout calculation and margin.
- Line 331: In the child-process polling branch around try_wait, preserve the
wait error; when try_wait returns Err, kill and reap the child before returning
that error, rather than breaking into reader.join() while Node may still be
running.

Let the environment override shorten a declared timeout.
If a command declares --timeout 600, AGENT_BROWSER_OPENCLI_TIMEOUT=1 still produces a 660-second limit. The max operation prevents the override from stopping a stalled long-timeout command at the requested limit. When the override is set, use it as the effective limit; otherwise, use the greater of the default and the declared timeout plus its margin.

Clean up the child when try_wait fails.
If try_wait() returns Err while Node is still running, this branch leaves Node running and proceeds to reader.join(). The reader can then wait for stdout until Node exits, with no deadline or reported wait error. Kill and reap the child on this branch, then return the wait error after cleanup.

Make the default-timeout test independent of the environment.
If AGENT_BROWSER_OPENCLI_TIMEOUT is set to a value other than 300, this assertion fails even though run_timeout() follows its configured override. Test the default through an environment-independent helper, or isolate and restore the variable for this test.

Two gaps in #407:
npm.cmdthere andCommanddoesn't apply PATHEXT, sosite updatesilently skipped OpenCLI. It now callsnpm.cmdon Windows.timeoutarg + 60s when larger (login flows), withAGENT_BROWSER_OPENCLI_TIMEOUTto override. Stdout is read on a thread so a large result can't block on a full pipe while waiting.Verified:
AGENT_BROWSER_OPENCLI_TIMEOUT=1 chrome-use site hackernews/bestfails with exit 1 and the timeout message; without it the command returns data.cargo test --release: 1482 passed.Summary by CodeRabbit
