Game server checks in with the API; drain state from it when enabled (OPE-432) - #5366
Merged
Conversation
Multi-server v2, priority 3 (OPE-432). Every server with a public host
POSTs {site, letter, host, version, numWorkers, liveGames} to
/cluster/checkin every 10s with the deploy API key, so the API's list
shows what is actually running. The reply carries this server's state.
The reply is obeyed (setActive) only when CLUSTER_STATE_SOURCE=api; by
default the drain decision stays with today's apex colour poll, which is
not started at all under the api source so two deciders never fight. A
failed check-in (404 from an API without the registry yet, a challenge
page, a network error) is "no change", never a drain.
Workers add liveGames (GameManager.activeGames) to their lobbyList
report; the master sums them for the check-in. Optional in the schema so
an older worker build reports zero rather than being rejected.
deploy.sh passes CLUSTER_STATE_SOURCE through to the container, and both
deploy workflows read it from vars.CLUSTER_STATE_SOURCE (unset today).

The fake GameManagers in HostedLobbyListing and WorkerLobbyServiceDrain predate activeGames(), so every test that drives a lobbyList report threw "this.gm.activeGames is not a function" once WorkerLobbyService started reporting liveGames. Also assert the count on the far edge: one case drops the sendToMaster stub and captures what the worker actually hands process.send, so a liveGames that is dropped between the report and the wire fails. Messages that are not ours are forwarded to the real channel, since vitest's fork pool talks to its parent over it.

"Dev has no public host" read as if openfront.dev doesn't register. What has no public host is local development: npm run dev sets DOMAIN=localhost with no SUBDOMAIN, so publicHost() is undefined and there is nothing to register. Every deployed host registers under its own site: the apex behind the load balancer via SITE_HOST, else beta, alpha, nightly, main, the colours and branch previews under themselves. Mirrors such as the openfront.dev apex serving nightly are an alias table in the API, never something a server reports about itself, so say that next to `site`. The standalone case becomes a test.each over a branch preview, beta (openfront.io) and nightly (openfront.dev), so the two deployed hosts most likely to be assumed apex-backed are covered by name.

The reply vocabulary grew a third value in infra #700: open, draining, fenced. The schema here still had two, so a fenced reply failed to parse, sendCheckin returned null, and the caller read that as "no change" -- a server an operator had deliberately fenced would have carried on taking new games, the exact opposite of the intent. Extend the enum to the three. applyCheckinState is unchanged in behaviour (active is state === "open"), so draining and fenced both stop new games; the comments now say that is deliberate, and that anything we fail to recognise stays null rather than being guessed as open. Tests: a fenced reply parses and drains under the api source, and the unknown-state case moves to a value outside the vocabulary.

…version, then flag it as latest (OPE-433) (#5369) Roadmap item 4 of **Server list v2** (`docs/MultiServer.md`, designed in #5365): the deploy pipeline starts producing the objects the static Worker will serve, and tells the API which commit new players of a site should get. Nothing reads any of this yet — the Worker does not exist and the API has no registry — so the uploads are additive and prod is unaffected. This lands before the cut because it touches CI. ## What a deploy now publishes Per **site** and per **version**, alongside the hashed assets and the existing `index-<short>.html`: ``` game_assets/sites/<site>/v/<short>/index.html game_assets/sites/<site>/v/<short>/desktop/release.json game_assets/sites/<site>/v/<short>/desktop/version.json ``` Site is `SITE_HOST` when the deployment sits behind a load balancer, else `<subdomain>.<domain>`; version is the 7-char prefix of `static/commit.txt`. All three go through the existing `PUT $R2_ENDPOINT/game_assets/upload/<urlencoded key>`, which prefixes `game_assets/` itself — the key layout settled with the infra registry PR. Both renderers run inside the freshly built image with the live container's env file, exactly as the replay shell already does, so what is published is what that build's server would itself have produced. ## The page carries no server `renderHtmlContent(path, { perServer: false })` omits `cluster`, `instanceLetter`, `instanceId`, `serverHost` and `siteHost`. A page served to every player of a version must not name one server — the client asks the API for the server list instead. `index.html`'s three unconditional lines are now guarded exactly like `serverHost` and `siteHost` already were, so **a render that supplies the locals is byte-for-byte what it always produced**. I verified that directly: a throwaway test rendered `origin/main`'s template and this one side by side under identical env and compared, for both a set and an empty `INSTANCE_ID`. The committed test asserts the exact rendered block instead — order, eight-space indentation, trailing commas. No new placeholder was added. openfront-desktop renders this same template itself and a missing local is a `ReferenceError`, i.e. a blank window; guarding an existing one is safe, because the shell supplies a value and the line still emits. `vendorTemplate.test.ts` over there keeps passing. The legacy `index-<short>.html` upload deliberately **keeps** the server values, until OPE-431 lands — today's client throws without a worker-count source. ## The descriptors move earlier, not elsewhere `src/server/RenderDesktopDescriptor.ts` builds the descriptor the game server already serves at `/desktop/*.json`, from the same `buildDescriptor` with the same env-derived opts (`clientVersion` = `GIT_COMMIT`, `requireCdnBase` iff prod), one deploy earlier. Publishing it per version lets the Worker answer for a site with no game server reachable, and makes a rollback a pointer flip rather than a redeploy. `release.json`'s `template.html` stays the raw EJS template by design — the Steam shell renders it itself. **Worth a look:** the CLI redirects stdout-bound logging to stderr before loading `DesktopRelease`. `DesktopRelease` imports `Logger`, and dotenv's "injected env" banner, `Logger.ts`'s OTEL line and winston's `Console` transport (stdout for *every* level, including `buildDescriptor`'s empty-`cdnBase` warning) all write to stdout. Any one of them would have prefixed `release.json` with prose that no Steam client can parse. That is why the module imports are dynamic — a static import is hoisted above the rebind, and `prettier-plugin-organize-imports` would reorder it anyway. There is a test asserting stdout is pure JSON while the noise is still readable on stderr. ## Flagging `latest` `update.sh` ends by POSTing `{ site, version }` to `${R2_ENDPOINT}/cluster/latest`. It runs **last, after the new container is up**, because the API refuses a version no server has checked in for — and that refusal is the interlock that stops a deploy pointing every player at a build that cannot serve them. There is no separate health wait in `update.sh`; this retry loop is the closest thing to one, and CI's own "Wait for deployment to start" polls `/commit.txt` afterwards. | Response | Outcome | | --- | --- | | `200` / `204` | Logged, done. | | `404` | The API predates the registry. Warn and continue, never retried, never strict — the expected answer everywhere today. | | `409`, `000`, `5xx` | Retried every 5s for up to 90s; servers register within ~10s of boot. | | `4xx` | A bad key or malformed request. Decided immediately — retrying cannot fix it. | Past the retries it warns and continues, because the page and its servers still come from `BOOTSTRAP_CONFIG` and nothing a player sees has changed — **unless** `CLUSTER_STATE_SOURCE=api` is in the site's env file, which says its clients take the server list from the API. An unflagged version then means no server is `open` and nobody can start a game, so the deploy fails rather than reporting a success it did not achieve. The passthrough for that variable comes from #5366, so it is absent on every site today and the lenient path is what runs. Two deliberate extensions to the spec: an unreachable or 500-ing API is treated like a 409 (the deploy is equally unfinished either way), and in strict mode any non-200/404 fails, not only 409. Silently succeeding on a 500 when clients read the API is the same failure 409-strict exists to prevent. ## Tests - `tests/server/RenderHtml.test.ts` — the environment-only and full renders of the **real** `index.html`. There was no test rendering it before; every existing case used a one-line stub. Also pins that `instanceId` survives a full render when it is empty (the guard keys off the rendered local, the JSON string `""`, which is truthy). - `tests/RenderDesktopDescriptor.test.ts` — the CLI's output shape, the `--version-pointer` form, the production CDN requirement, and stdout purity. It stages the shipped file at the same relative depth against a fixture build rather than paraphrasing it, so the real argument handling and the real `BuildOpts` are what run. - `tests/UpdateFlagLatest.test.ts` — `flag_latest`'s decision table, extracted from `update.sh` between markers and driven by a scripted `curl` on `PATH`, the way `tests/UpdateRestartPolicy.test.ts` tests the restart policy. `npx tsc --noEmit`, `npm run lint`, `prettier --check` and `bash -n update.sh deploy.sh` all clean; full `npx vitest run` green (451 files, 5539 tests).

…(OPE-432) (openfrontio#5366) Multi-server v2, priority 3 (OPE-432, parent OPE-429). Independent of openfrontio#5365; both must be on `main` before the v34 cut. **Dormant by default**: an extra best-effort POST every 10s that tolerates a 404, and the drain decision stays with today's apex colour poll until `CLUSTER_STATE_SOURCE=api` is set. ## What - **Check-in loop** (`src/server/ClusterCheckin.ts`, wired in `Master.ts`): every server with a public host POSTs `{ site, letter, host, version, numWorkers, liveGames }` to `${jwtIssuer}/cluster/checkin` with the deploy API key, every 10s. `site` is `SITE_HOST` behind a load balancer (`openfront.io` for blue/green), else the deployment's own host, so every deployed host registers under its own site: `beta.openfront.io`, `alpha.openfront.dev`, `nightly.openfront.dev`, `main.openfront.dev`, `green`/`blue.openfront.dev`, and each `<branch>.openfront.dev` preview (never in main's list). Hostnames that merely mirror a deployment (the `openfront.dev` apex → nightly; `beta.openfront.io` when it points at staging) are resolved by an alias table in the API (OPE-434), not here. Only local development (`npm run dev`: `DOMAIN=localhost`, no `SUBDOMAIN`) has no public host and registers nowhere. - **State source switch:** `CLUSTER_STATE_SOURCE=api` makes the reply (`{ state: "open" | "draining" }`) drive `lobbyService.setActive`, and the apex `/api/health` colour poll is not started at all, so two deciders never fight. Unset (today) keeps the apex poll and only logs. A failed check-in is "no change", never a drain: an unreachable API must not stop the live server from scheduling lobbies. - **Live-game count:** workers add `liveGames` (`GameManager.activeGames()`) to their existing `lobbyList` IPC report; the master sums them. Optional in the schema so an older worker build reports zero rather than being rejected. - **Plumbing:** `deploy.sh` writes `CLUSTER_STATE_SOURCE` into the container env file; `deploy.yml` and `release.yml` read it from `vars.CLUSTER_STATE_SOURCE` (unset today). Flipping it is a GitHub variable change plus a redeploy, no code. `docs/MultiServer.md` gets its check-in section once openfrontio#5365 (which adds the "Server list v2" chapter) lands, to avoid a conflicting edit in the same region. ## Tests `tests/server/ClusterCheckin.test.ts` (body per environment, dev opts out, request shape and auth header, null on 404 / bad state / HTML / network error, the source switch), `tests/server/MasterLobbyServiceLiveGames.test.ts` (summing, older worker builds, dead workers).
