perf(desktop): provider checks no longer compete with server startup by t3dotgg · Pull Request #35712 · pingdotgg/t3code

t3dotgg · 2026-11-13T00:04:18Z

The desktop app shows nothing useful until the bundled server is ready. Three small waits sat on that path: provider checks spawned claude, codex app-server and ACP runtimes while the server was still starting, the desktop learned about readiness from a 100 ms poll, and the auth token was minted only when the window asked for it.

Now:

Provider checks wait for server startup. The first check of each provider runs after the server publishes ready. This holds in every mode, so a headless server still checks. Settings show the cached status until the check finishes.
The server tells the desktop it is ready. It writes one line on the control pipe the desktop already reads. The HTTP poll stays as the fallback, so WSL still works.
The token is minted at readiness, before the window asks.
The server is spawned before the menu, passkeys and SnapShot setup, not after.

Not done: spawning the server before Electron is ready. The telemetry publisher needs powerMonitor, which only works after ready, and the backend pool depends on it.

Verified

New tests: the first provider check waits for server ready, and the backend becomes ready from the ready line while HTTP probes hang. The start order test now checks that the backend starts before the menu.
vp run check:changed passes.
I booted the real server on a throwaway home. It reached ready, and the first provider checks started 0.5 ms after server.startup.ready.publish. So the wait does not block startup.

Not verified: the packaged Mac app was not run, so startup time was not measured. The expected gain is small, up to about 100 ms from the poll plus less disk and CPU contention on a cold start.

This overlaps #28991 in DesktopApp.ts and managedProvider.ts. Whichever lands second needs a merge.

🤖 Generated with Claude Code

- Spawn the local backend right after the updater sets canInstallUpdates, before menus, passkeys, and SnapShot setup. - The server writes a serverReady line on the desktop control fd once it accepts requests. The desktop races it against the HTTP poll, which stays as the fallback for WSL and other backends without the fd. - Mint the local bearer token as soon as the backend is ready, before the renderer asks for it. - Hold each provider's first status check until server startup finishes, so provider CLIs do not compete with the first client load. The cached status shows until then. Co-Authored-By: Claude Opus 5.5 <[email protected]>

Approvability

Verdict: Approved at f6e6a04

Macroscope's review found this PR approvable — The change starts the desktop backend sooner and delays initial provider checks until server readiness, with HTTP polling retained as a fallback. It preserves existing authentication and exposure settings; remaining discussion concerns limited performance edge cases and test organization.

Walkthrough

The server now announces readiness over desktop telemetry. The desktop backend can use that signal alongside HTTP readiness polling, and desktop startup separates backend startup from later bootstrap work. The provider host also exposes server readiness so the initial provider check can wait for it.

Changes: Startup readiness

Layer / File(s)	Summary
Define and publish server readiness `packages/contracts/src/resourceTelemetry.ts`, `apps/server/src/resourceTelemetry/DesktopTelemetryReceiver.ts`, `apps/server/src/server.ts`, `apps/server/src/serverLifecycleEvents.ts`	The telemetry contract adds a version-1 `serverReady` message. The server announces readiness after command readiness, and lifecycle events expose an effect that completes on the first `ready` event.
Coordinate desktop startup with backend readiness `apps/desktop/src/backend/DesktopBackendManager.ts`, `apps/desktop/src/telemetry/DesktopTelemetryPublisher.ts`, `apps/desktop/src/app/DesktopApp.ts`, `apps/desktop/src/backend/DesktopBackendManager.test.ts`, `apps/desktop/src/app/DesktopApp.test.ts`	The backend manager races HTTP readiness polling against the telemetry signal. Desktop startup starts the backend before menu and window setup, then runs bootstrap with the startup result. Tests cover signal-based readiness and startup ordering.
Wait for server readiness before provider checks `packages/provider-core/src/server/ProviderHost.ts`, `apps/server/src/provider/ProviderHostLive.ts`, `packages/provider-core/src/server/managedProvider.ts`, `packages/provider-core/src/server/managedProvider.test.ts`, `apps/server/src/provider/Drivers/ClaudeMaintenance.test.ts`	The provider host optionally exposes a server-readiness effect. The managed provider waits for it before its initial forced check. Tests verify that the check waits for readiness and update the host mocks.

Estimated code review effort: 3 (Moderate) | ~25 minutes

Merge Risk: Low · up to f6e6a

Provider checks triggered by settings changes or by the periodic refresh can still start before the server is ready, which could slow startup in rare cases. The change is otherwise bounded and its core readiness coordination is tested, so it is mergeable with owner awareness.

Full details: Title check

Explanation

The title "perf(desktop): provider checks no longer compete with server startup" matches the main change. The changeset defers the first provider checks until the server publishes ready, and it also moves the server start earlier and adds a ready signal over the control pipe. The title covers the primary intent, and the objectives confirm the same focus.

Full details: Description check

Explanation

The description follows the template. It has Problem, Change, Scope, and Verification sections, and it states the problem, the changes, and the overlap with #28991. Verification lists focused tests, a check run, and a manual boot with observed timing, and it states what was not verified. The Scope section explains the change as a performance fix but does not link an issue or a maintainer request. The template asks for a linked bug issue or a reason for no issue, so that section is incomplete. The Problem section also does not give explicit reproduction steps. The description is mostly complete, so the check passes.

This repeats the existing initial-check case immediately above. Could you fold the readiness gate into that test, retaining its snapshot and completion assertions?

Minor · Performance & Scalability · Quick win

Gate periodic checks on server readiness too.

If startup exceeds refreshInterval and background demand is enabled, the worker at Lines 410-438 calls refreshOnInterval before host.awaitServerReady completes. That path can call input.checkProvider at Line 181. The first provider CLI can therefore still compete with server startup.

Apply the readiness gate to the periodic worker. Extend the existing readiness test with background demand enabled and an interval that expires before readiness.

As per coding guidelines, “Backend behavior changes ship with focused tests for that behavior.”

Note
🤖 Claude Fable 5.2 responding on behalf of Theo

Not changing this. The periodic worker only runs a check before ready when server startup takes longer than the provider health refresh interval. Startup is about 100 ms in the trace I took, and the interval is far longer, so this path does not happen in practice.
