feat(web): one sidebar click updates every machine and provider

[t3dotgg]

If you run T3 Code on several machines, updating meant visiting each one: the desktop app from the sidebar, each server from Connections, and providers from Provider settings. Now the sidebar update button does all of it in one click.

How it works

When any connected machine has work, the button shows what it will update ("Update this app, 2 servers, and 3 providers"). One confirm dialog lists each machine on one line, then:

1. Providers update on every connected machine. This finishes before any server restarts.
2. Servers on other machines move to the version this desktop app is about to install. On web, they move to the web app's version. The existing updateServer flow waits for each server to reconnect.
3. This desktop app installs last, because its relaunch ends the run. Its download runs alongside steps 1 and 2. A failed download skips only the local install.

The button uses the server update icon from Connections (circle with up arrow). The download arrow stays for a local-only app update. During a run the button is dimmed, and it shows download progress while this app downloads.

Rules for which servers are included:

• Server updates show only after npm has the version. The client checks registry.npmjs.org/t3/<version> and re-checks every 5 minutes. Provider updates, remote desktop apps (they use their own update feed), and the local install are not gated.
• Servers hosted by this desktop app (the primary backend and local WSL backends) are skipped, because the app install updates them.
• A background service stays on its release channel. A nightly desktop app does not move a stable server to nightly. A remote desktop app follows its own update feed.
• Disconnected machines, sessions without environment:maintain, and installs that need a manual update are skipped. The existing notice and Connections settings still handle them.

With only a local app update, the button keeps today's flow: download, then click to restart. Mobile already has per-environment updates and is not changed. The legacy sidebar is not changed.

No contract or server changes. useServerUpdate and the provider batch (now useProviderUpdates) are reused as they are.

Screenshots

Web, with two outdated providers on the connected server.

Before (main)	After

Click opens one confirm dialog with one line per machine. When restarts will stop running threads, it says how many, and how many can resume afterwards:

This screenshot uses a temporary local patch to show 2 remote servers and 3 running threads, because the dev environment has no remote server that is behind or agent that is running. The patch is not committed.

With servers and this app included, the lines read like This app: 0.0.50, restarts last and alvin: server to 0.0.50, Codex, Claude. The unit tests cover this text.

Running threads

The dialog counts the running threads on the machines that restart: each server it updates, plus this app's own servers when this app installs. Provider updates restart nothing. Threads on a server with Continue threads after restarts on can resume afterwards. Since #18461 that setting is on by default, with a limit of 3 automatic resumes in a row, and it never resumes a thread that waits on the user. The text says "can resume", not "will", because recovery still skips some threads.

The dialog does not change the setting. An earlier version had a checkbox that saved it on every restarting server. With the safe default, that checkbox only added a way to turn continuation off everywhere by accident, so it is gone.

Verification

• updateEverything.logic.test.ts covers which servers are chosen (this app's own server, release channel, scope, disconnected, manual, up to date), the run order (servers wait for providers, the local install runs last, a failed download skips only the install), and the summary and per-machine text.
• The tests also cover which servers restart (updated servers, plus this app's servers only when it installs) and which of them resume threads.
• Web typecheck, targeted lint, knip, and sidebar tests pass (14).
• Checked in a web dev client: the button, tooltip, and confirm dialog render (screenshots above). I did not confirm the run. Not tested with several machines or in a desktop build, which needs a second paired server.

Approvability

Verdict: Not approved

Macroscope's review found this PR not approvable — This PR changes the sidebar into a new cross-machine update workflow that can update providers, restart remote servers, and relaunch the desktop app, with version and npm-release gating plus running-thread interruption concerns. The substantial production logic and changed default action make this broader than a small isolated update.

📝 Walkthrough

Walkthrough

The sidebar now offers a coordinated update flow for eligible providers, servers, and the local app. The flow checks server eligibility and npm publication, then coordinates update order and presents confirmation details.

Changes

Combined Updates

Layer / File(s)	Summary
Select eligible server update targets apps/web/src/components/sidebar/updateEverything.logic.ts, apps/web/src/components/sidebar/useUpdateEverything.ts, apps/web/src/state/npmRelease.ts, apps/web/src/versionSkew.ts	Server targets are filtered by connection, maintenance permission, update capability, target version, and release channel. The npm release hook checks for an exact published version. Version mismatch resolution can compare against a specified client version.
Coordinate provider, server, and local updates apps/web/src/components/sidebar/updateEverything.logic.ts, apps/web/src/components/sidebar/useUpdateEverything.ts, apps/web/src/components/ProviderUpdatesAction.tsx, apps/web/src/components/ServerUpdateAction.tsx, apps/web/src/components/sidebar/updateEverything.logic.test.ts	The update run overlaps local download with provider updates, then updates servers and installs the local app if its download succeeds. Tests cover target selection, restart-machine collection, update order, failure handling, and summary text.
Present and trigger combined updates apps/web/src/components/sidebar/SidebarUpdatePill.tsx, apps/web/src/components/sidebar/DesktopUpdateStatusIcon.tsx, apps/web/src/components/sidebar/UpdateEverythingDialog.tsx, docs/user/updating.md	The sidebar presents combined-update status and confirmation details. Local download and install actions use helpers that handle action errors and thrown failures. The documentation describes update order and target rules.
