test(cli): stop judging a stale record on a port another test can take - #4403
Conversation
The fallback-port fixture records a port from allocateFreePort, which reports the port it has already released. On a four-shard runner every other test binding an ephemeral port is a candidate to take it, and when that happens status finds a listener on the recorded port, reports the record as live, and the assertion fails against something the test never set up. It failed exactly that way on the preview promotion run while the same commit passed on dev. Confirm the recorded port refuses immediately before and immediately after the status probe, and re-allocate when something took it in between. The assertion is unchanged and no weaker: a run only counts when the endpoint demonstrably refused across the whole probe, and exhausting the attempts fails with that reason rather than silently passing.

If another shard binds recordedPort after the first refusal check and releases it before the second—while the blocking runStatusJson call is executing—both checks still return true, but observed.proxy.staleProcessState is false. Assigning that result to parsed terminates the retry loop and reproduces the flaky assertion this change is intended to fix. Retry when the observed state is not true; because the configured port remains occupied, a genuinely broken implementation will still exhaust all attempts and fail.

Accept only ECONNREFUSED as a refusal.
createConnection from node:net can emit errors that do not indicate a refused connection. At tests/cli/cli-status-json.test.ts:897, those errors can make both refusal checks pass without exercising the stale-port path. Resolve true only when error.code === "ECONNREFUSED".
Proposed fix
- socket.once("error", () => settle(true));
+ socket.once("error", error => settle(error.code === "ECONNREFUSED"));📝 Committable suggestion
‼️ IMPORTANT
Carefully review the code before committing. Ensure that it accurately replaces the highlighted code, contains no missing lines, and has no issues with indentation. Thoroughly test & benchmark the code to ensure it meets the requirements.

Product tree is dev at 7bfb2ad. Only package.json differs, carrying the stable channel version 2.52.0. This promotion follows a CI repair and a regression sweep: dev had drifted 79 commits past its last finished run and the one run allowed to complete had failed. lidge-jun#4390 fixed an integration test that never denied anything and had been red on dev since lidge-jun#4342; lidge-jun#4396/lidge-jun#4397/lidge-jun#4398 closed four gaps in the quota avoidance contract lidge-jun#4368 introduced; lidge-jun#4403 made a port fixture deterministic.

Summary
a fallback-port record is judged on the recorded port, not the configured onefixture deterministic. It records a port fromallocateFreePort, which returns a port it has already released, so on a sharded runner another test can bind it beforestatusprobes. When that happensstatuscorrectly sees a listener, reports the record as live, and the assertion fails against a setup the test never established.Verification
test 3/4, while the identical product tree passed on dev in 34691465021. Same code, different outcome, which is what identifies it as port contention rather than a regression.Checklist
