fix(e2e): reap connect after dashboard forward handoff - #9614
Conversation
Signed-off-by: Aaron Erickson <aerickson@nvidia.com>
📝 WalkthroughWalkthroughAdds a dashboard connect handoff runner with bounded output capture, forward-start detection, timeout and cancellation handling, process cleanup, artifact persistence, integration coverage, and semantic-phase policy registration. ChangesDashboard connect handoff
Estimated code review effort: 4 (Complex) | ~45 minutes Merge Risk: 🟡 Moderate · up to This PR changes dashboard end-to-end process handoff and cleanup. Large timeout values may trigger near-immediate forced cleanup, while transient reachability errors can produce false failures; a PID-file race may also mask the underlying test result. These bounded correctness risks require follow-up before merge. Sequence Diagram(s)sequenceDiagram

forwardPid check so process termination, waitForProcessExit, and the exit
assertion are skipped when PID creation failed. Move or retain the process
liveness assertion for a known PID in the try block, ensuring the test proves
the spawned process exists without allowing cleanup assertions to mask the
original failure.

dashboard connect-handoff test with an exact assertion on the parsed forward

stopped forward while preserving the existing positive running-state behavior.
- Around line 225-248: The dashboard reachability probe in the forwardReachable
command currently exits on the first connection error, allowing transient
ECONNREFUSED failures. Update the inline Node.js probe to retry connections with
bounded backoff until success or the existing 5-second probe deadline, while
preserving cleanup and exit behavior so the overall 10-second command timeout
remains sufficient.

Reject timer delays that Node.js clamps to 1 ms.
If timeoutMs or stopGraceMs exceeds 2_147_483_647, Node.js schedules the corresponding timer with a 1 ms delay. Reject these values and add tests for 2_147_483_648 for both budgets.

Read the PID file once.
existsSync(pidFile) followed by readFileSync(pidFile, "utf8") has a TOCTOU window. If fixture cleanup removes the file between these calls, the finally path throws and can mask the original test failure. Read once and catch ENOENT; keep other filesystem errors fatal.

Summary
Refs #9606. Stacked on #9323.
Related delivery: #9140. Related epic: #7744.
The dashboard remote-bind target recovered a missing forward successfully, then waited for ordinary interactive
nemoclaw connectto exit before evaluating the already-emitted recovery proof. The shell remained attached by design until the generic command timeout killed its process group, changing the historic no-exit result into exit 143 and preventing the target from reaching its independent bind and audit assertions.This change observes the real connect child asynchronously. Once the existing forward-recovery proof appears, it signals and reaps only the attached connect leader and requires its captured descriptors to close without forced cleanup. A correctly backgrounded forward remains live for the existing exact owner, all-interface bind, reachability, and security-audit verification. Ordinary interactive and noninteractive
connectbehavior is unchanged.Changes
