AIT-395: fix both Windows bugs — command shims and the teardown abort (0.14.16) - #59
Conversation
…lthy install `spawnSync` does no PATHEXT expansion, so a bare `npm`/`npx`/`claude` is ENOENT on Windows even when the tool is installed, and naming the `.cmd` shim directly is EINVAL. doctor reported "not found on PATH" for npm and npx and exited 1 on a working install; `hookmyapp mcp` had the same bug in all five `claude` spawns. Route every external-tool spawn through `runTool()`, which goes via cmd.exe `/c` with separate args on Windows — `shell: true` would concatenate argv and mangle the JSON payload `claude mcp add-json` expects. Also demote npm/npx from hard checks to informational: the CLI never shells out to npm, so a probe that can't see it says nothing about whether the CLI works. A hard gate there blocked agents from completing onboarding on Windows. Reported by a customer on Node 24.14.0 / CLI 0.14.13 (AIT-395, sup_81).

When the Windows display language is not English and Claude Code is absent, cmd.exe emits a translated command-not-found diagnostic, so this English-only substring check returns false. Consequently, removeClaudeMcp() reports a spurious cleanup warning during logout, while getClaudeMcpStatus() misreports the missing installation as merely “not connected”; use a locale-independent probe or exit condition instead.

`flushAndExit` called `process.exit()` the moment the telemetry drain resolved. On Windows that aborts the process while libuv handles are still closing: Assertion failed: !(handle->flags & UV_HANDLE_CLOSING), file src\win\async.c Exit code 9, AFTER the command printed its correct output — reported on login, notifications and workspace list, which makes exit codes unusable for scripting and makes a successful login look like a failure. Set `process.exitCode` and let the loop drain instead, and close fetch's keep-alive sockets (Node parks them in a global undici dispatcher that outlives the request) so there is nothing left holding it. An unref'd watchdog still force-exits if some handle we don't own keeps the process alive, which is the only case the old hard exit was buying us. Measured on the built CLI: 24ms between last output and exit. `flushAndExit` no longer terminates, so the --help/--version path in main() returns explicitly instead of falling through to parse-error handling. Add a windows-latest CI job that builds, runs the suite, and asserts `doctor --json` sees npm/npx and exits 0. Both Windows bugs in AIT-395 shipped because every job was ubuntu-only; mocked tests with an injected platform cannot catch either. Refs AIT-395, sup_81.
First run of the suite on windows-latest surfaced 7 failures, none of them Windows bugs in the CLI — the tests themselves assumed POSIX: - mcp.test.ts mocked node:child_process and asserted the raw spawnSync argv, which on Windows legitimately carries the cmd.exe /c prefix. Mock the `runTool` seam instead, so the assertions describe what mcp.ts asks to run rather than how the platform spells it. - secrets.test.ts asserted mode 0o600. Windows has no mode bits; the file is protected by the per-user profile ACL. POSIX-only. - eperm-actionable.test.ts builds a read-only dir with chmod, which is a no-op on Windows, so the EPERM it exists to trigger never happens. POSIX-only. - notifications-nudge.test.ts split a path on '/', which yields the whole absolute path on Windows and produced a doubled mkdir target. Use basename. - billing.test.ts's fake-timer poll loop needs more than the default 30s of real time on the Windows runner. Refs AIT-395.
The fake-timer poll tests in billing.test.ts step timers in 100ms increments; the windows-latest runner is slow enough to blow the 30s default doing it. A runner speed difference, not a product bug. One config knob rather than a per-test timeout that the next poll test forgets to copy. Refs AIT-395.

For the Undici version supported by this project, does Dispatcher.close() wait for active requests to settle, and does it provide a timeout option?
💡 Result:
Yes, the Undici Dispatcher.close method is designed to gracefully wait for enqueued requests to complete before resolving the returned promise or invoking the optional callback [1][2][3]. Regarding a timeout option, Dispatcher.close does not provide a parameter to specify a timeout for this closing operation [1][3]. While the Undici library includes various timeout settings for individual requests (such as headersTimeout and bodyTimeout) [3], these do not apply to the close method itself. Consequently, if active requests hang, the close operation will also wait indefinitely unless the underlying requests themselves are subject to their own timeouts or are manually aborted [4][3].

Node.js supported by package.json global undici dispatcher close() behavior Node 18 20 22 close waits active requests no timeout
💡 Result:
In Node.js (including versions 18, 20, and 22 which utilize Undici), the dispatcher.close method is designed to gracefully close the dispatcher by waiting for enqueued and in-flight requests to complete before resolving the returned promise or invoking the provided callback [1][2][3]. Key behaviors include: 1. Graceful Shutdown: When called, the dispatcher stops accepting new requests and waits for existing active or enqueued requests to finish [1][4][5]. 2. No Explicit Timeout: The standard close method does not accept a timeout parameter and does not inherently force-close active requests after a specific duration [1][2][6]. 3. HTTP/2 Considerations: While the standard behavior for HTTP/1.1 is to wait for requests to complete, there have been documented instances where HTTP/2 implementations may terminate pending requests prematurely due to internal handling of the protocol's stream lifecycle [7]. 4. Alternative - Destroy: If you need to force-close a dispatcher without waiting for active requests to complete, the.destroy method is available. Unlike close,.destroy will immediately terminate active requests and clean up resources [1][3]. In summary,.close is the "polite" way to shut down, ensuring pending work finishes without a built-in timeout, whereas.destroy is the "abrupt" way to shut down immediately.

Start the watchdog before awaiting closeHttpAgent.
Dispatcher.close() waits for active requests and has no close-timeout option. A hung request can prevent flushAndExit() from reaching the watchdog setup.
Set process.exitCode and start the unref'd watchdog before await closeHttpAgent(), or bound closeHttpAgent() with EXIT_DRAIN_MS.

…, CI hardening From CodeRabbit on #59: - `isCommandNotFound` matched only cmd.exe's English diagnostic, so a German or Japanese Windows would be told Claude Code is installed when it isn't. Check status 9009 first — cmd.exe translates the message, not the status. - `dispatcher.close()` waits for in-flight requests and takes no timeout, so one hung fire-and-forget request would have held the CLI open forever where the old hard exit killed it. Race it against 1s, then `destroy()`. - The Windows doctor smoke failed on any runner network blip. Parse the JSON first (a teardown abort emits none — that is the real signal) and only enforce the exit code when the network check itself passed. - `persist-credentials: false` on both checkouts: every later step runs repo code and nothing here pushes. Tests: fake timers in the flushAndExit specs so the unref'd watchdog can't fire against a restored real `process.exit` and kill the worker; restore ComSpec after the spawn-tool cases; cover the 9009 path. Refs AIT-395.
billing.test.ts's fake-timer poll tests blew the 30s default on ubuntu too, not just Windows — they step timers up to 500 times and CI load decides whether that fits. One budget for both runners. Refs AIT-395.
…nfig The describe block in billing.test.ts closes with its own `}, 30_000)`, and a suite-level budget wins over vitest.config.ts — so the previous commit's 60s config never applied to the tests that were timing out. Raise it where it is actually read. Refs AIT-395.
Fixes AIT-395. Both bugs a customer reported from Windows 11, Node 24.10.0, CLI 0.14.13 (support ticket
sup_81).Bug 1 — every networked command aborted at teardown (exit 9)
Commands printed their correct output and then died:
Reported on
login,notificationsandworkspace list.flushAndExitcalledprocess.exit()as soon as the telemetry drain resolved, which on Windows aborts the process while libuv handles are still closing. A successful login looked like a failure, and exit codes were unusable for scripting or CI.Fix: set
process.exitCodeand let the loop drain instead of hard-exiting, and close fetch's keep-alive sockets first (Node parks them in a global undici dispatcher that outlives the request), so nothing is left holding the loop. An unref'd watchdog still force-exits if a handle we don't own keeps the process alive — the only case the old hard exit was actually buying us. Measured on the built CLI: 24ms between last output and exit, no added latency.flushAndExitno longer terminates, so the--help/--versionpath inmain()returns explicitly instead of falling through into parse-error handling.Bug 2 — bare spawns never resolve
.cmdshimsspawnSyncdoes no PATHEXT expansion, so a barenpm/npx/claudeis ENOENT on Windows even with the tool installed, and naming the shim directly is EINVAL.doctorreported npm, npx and Claude Code as missing and exited 1 on a healthy install;hookmyapp mcp install --agent claudealways failed, sologinnever auto-configured the MCP server on Windows.Fix: new
lib/spawn-tool.tswithrunTool(), which routes through cmd.exe/cwith separate args on Windows. Notshell: true— that concatenates argv instead of escaping it and mangles the JSON payloadclaude mcp add-jsonexpects (the customer hit exactly that while working around it).isCommandNotFound()handles the Windows shape, where the spawn succeeds and only cmd.exe's output reveals the missing command.doctorand all fiveclaudespawns inmcp.tsroute through it.npm/npx also drop from hard checks to informational: the CLI runs on Node alone and never shells out to npm, so a probe that cannot see it says nothing about whether the CLI works. As a hard gate it blocked agents from completing onboarding.
