[DO NOT MERGE] ACM-42591: Validate Go backend CI/CD pipeline changes

[Randy424]

Purpose

This is a validation PR for ACM-42591 (CI/CD pipeline for Go backend build, image, and deployment), not intended to merge. It exists to test this story's Containerfile/.tekton/CI changes against the real Konflux pipeline independently of #6779, which currently has its own separate, unrelated blockers (a merge conflict and a compile error in internal/config/config.go).

What's in here

• The Go backend ported from Ginxo/console (Kike's fork, PR ACM-42568 Migrate the console backend to Go #6779's head commit 45fa89082f) — app-logic code, not mine, included only so there's something real to build/lint/test against
• A one-line fix for the DisableEvents compile error present in ACM-42568 Migrate the console backend to Go #6779's head commit, included only to unblock this PR's own CI signal — the real fix belongs in ACM-42568 Migrate the console backend to Go #6779, not here
• Containerfile.acm/.mce: adds the Go build stage
• .tekton/console-acm-51/52-*, console-mce-mce-51/52-*: adds the gomod prefetch declaration required for Konflux's hermetic builds
• Root package.json/dev scripts pointed at Go tooling

What I expect to see

• Konflux builds (console-acm-51/52-on-pull-request, console-mce-mce-51/52-on-pull-request) should pass — this is the main thing being tested
• ci/prow/check and ci/prow/unit-tests-sonarcloud are expected to still fail: they depend on a separate openshift/release PR (giving the Prow runner image a Go toolchain) that hasn't merged yet

Test plan

• Confirm Konflux builds go green with the gomod prefetch fix in place
• Confirm ci/prow/check/unit-tests-sonarcloud fail specifically on "go: command not found", not something else, corroborating the openshift/release runner-image gap

📝 Walkthrough

Walkthrough

The pull request replaces the Node.js backend with a Go backend. It adds Go services, HTTP routes, Kubernetes integrations, proxies, SSE delivery, static assets, container builds, development tooling, startup wiring, and frontend event-stream integration.

Changes

Go runtime and build migration

Layer / File(s)	Summary
Go runtime, containers, and tooling backend/cmd/console/main.go, backend/go.mod, Containerfile.*, package.json, scripts/*, Makefile.prow	The backend builds as a static Go binary, runs through a Go entrypoint, and uses Go-based development, lint, test, certificate, and CI commands.
Backend development configuration backend/.air.toml, backend/.golangci.yml, backend/.gitignore, backend/README.md, backend/AGENTS.md, .vscode/launch.json	Development configuration and documentation now describe the Go backend. The Node.js ESLint and debugger configurations were removed.

Backend services and data flows

Layer / File(s)	Summary
Aggregation, authentication, and configuration backend/internal/aggregate/*, backend/internal/auth/*, backend/internal/config/*, backend/internal/hubresources/*, backend/internal/clusterproxy/*	Added application aggregation, status processing, filtering, pagination, RBAC checks, token handling, TLS configuration, dynamic settings reloads, hub lookups, and cluster-proxy resolution.
Informers and event delivery backend/internal/informers/*, backend/internal/events/*	Added discovery-driven informers, cache and snapshot handling, resource transformation, SSE hubs, compression, authorization filtering, RBAC role storage, and RBAC SSE delivery.
HTTP integrations backend/internal/clusterinfo/*, backend/internal/*proxy/*, backend/internal/oauth/*, backend/internal/rosa/*, backend/internal/upgraderisks/*, backend/internal/user/*, backend/internal/placementdebug/*	Added authenticated handlers for cluster information, Kubernetes and managed-cluster APIs, search, metrics, OAuth, ROSA, Ansible Tower, placement debugging, upgrade risks, user preferences, and VM operations.

HTTP server and frontend integration

Layer / File(s)	Summary
HTTP routing and assets backend/internal/server/*, backend/internal/cors/*, backend/internal/health/*, backend/internal/static/*	Added route registration, /multicloud aliases, CORS behavior, health probes, request logging, TLS serving, graceful shutdown, and static asset delivery with compression and cache handling.
Frontend watch loading frontend/src/components/*, frontend/src/hooks/*, frontend/src/lib/test-event-source.ts, frontend/webpack.config.ts	Frontend event loading now uses reusable stream and cache components. RBAC events use a separate loader. Reconnection, page activity, resource updates, and development proxying are covered by tests.

Data race on gotUA and gotAuth in the test handler.

ServeHTTP posts the chunks concurrently, so the Insights handler runs in two goroutines for the 101-ID input. bodies is guarded by mu, but gotUA and gotAuth are written without the lock. go test -race reports a race here. Move both writes inside the existing critical section.

Full client buffer silently discards events for up to 30 minutes.

When c.ch is full, the event is dropped and the client stays subscribed until purge (30 minutes) elapses. The stream has no replay path, so the browser keeps a stale cache without any error signal.

Drop the slow client immediately. Closing the channel ends ServeHTTP, and the EventSource reconnect rebuilds a consistent snapshot.

96-102: 🩺 Stability & Availability | 🟠 Major | ⚡ Quick win

Do not cache the namespace fallback after a lookup failure.

namespace sets haveCache = true even when fetchNamespace returned DefaultNamespace because the dynamic client failed or the MCE read failed. The fallback then persists for the process lifetime. On a hub where MCE runs in a non-default target namespace, one transient failure (missing RBAC at startup, API server restart) pins every later HostPort/ProxyURL call to cluster-proxy-addon-user.multicluster-engine.svc.cluster.local, so managed-cluster proxy and VM requests keep failing until the pod restarts.

Cache only successful resolutions. This also lets you avoid holding r.mu across the API call, which currently serializes concurrent proxy requests behind one round trip.

🐛 Proposed fix: cache only on success

 	r.mu.Lock()
-	defer r.mu.Unlock()
-	if r.haveCache {
-		return r.cachedNS
-	}
-	ns := r.fetchNamespace(ctx)
-	r.cachedNS = ns
-	r.haveCache = true
-	return ns
+	cached, ok := r.cachedNS, r.haveCache
+	r.mu.Unlock()
+	if ok {
+		return cached
+	}
+	ns, resolved := r.fetchNamespace(ctx)
+	if !resolved {
+		return DefaultNamespace
+	}
+	r.mu.Lock()
+	r.cachedNS = ns
+	r.haveCache = true
+	r.mu.Unlock()
+	return ns
 }

fetchNamespace then reports whether the lookup succeeded:

func (r *Resolver) fetchNamespace(ctx context.Context) (string, bool) {
	dc, err := r.dynamicClient()
	if err != nil {
		applog.Logger().Error("mce dynamic client", "error", err)
		return DefaultNamespace, false
	}
	ns, err := hubresources.MCETargetNamespace(ctx, dc)
	if err != nil {
		applog.Logger().Error("Error getting MultiClusterEngine", "error", err)
		return DefaultNamespace, false
	}
	if ns == "" {
		return DefaultNamespace, true
	}
	return ns, true

Chunk buckets stay empty; the redistributed apps are discarded.

🟡 Minor · Make the danger classification reachable. · backend/internal/aggregate/status.go:210-214

210-214: 🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

Make the danger classification reachable.

In computeDeployedPodStatuses, the progress branch handles every case where available < desired or desired <= 0. The later danger branch therefore cannot run for numeric resource values. Missing desired becomes 0 in searchFloat, and zero available is handled as progress or skipped when both values are zero. The intended danger cases are reported as progress, which changes deployed-status counts and sorting/filtering.

Handle item["desired"] == nil or zero available before the equality and progress checks.

🟡 Minor · Preserve an explicit zero in available. · backend/internal/aggregate/status.go:203-205

203-205: 🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

Preserve an explicit zero in available.

searchFloat maps a missing value, null, and numeric zero to 0. The fallback changes available: 0, current: 1, and desired: 1 to an effective available value of 1. The equality check then skips the resource. This does not report the workload as fully available because missingCount can still add scoreWarning, but it can omit the resource's scoreProgress classification and clear its messages.

Use current only when available is absent or null.

Queue an event before LOADED to cover the flush.

The source flushes eventQueue before it calls onLoaded. This test emits only LOADED, so the queue is empty and processEventQueue returns early. The assertion therefore does not test the flush named in the test title.

Cap the /operatorCheck request body before decoding.

/operatorCheck and /multicloud/operatorCheck reach operatorCheck after the cors.Middleware and requestLogger wrappers. auth.AuthenticateRequest validates the token, then operatorCheck calls io.ReadAll(r.Body). The server config sets only ReadHeaderTimeout, so an authenticated request can make io.ReadAll retain an arbitrarily large body and exhaust process memory.

Use http.MaxBytesReader and reject trailing data to preserve the current JSON parsing behavior.

🛡️ Proposed fix

-	body, err := io.ReadAll(r.Body)
-	if err != nil {
-		applog.Logger().Error("read operatorCheck body failed", "error", err)
-		w.WriteHeader(http.StatusInternalServerError)

Propagate informer cancellation into List and Watch requests.

cache.ListWatch in client-go v0.32.3 uses legacy callbacks. The reflector calls Watch synchronously and runs List in a separate goroutine. Because both callbacks pass context.TODO(), a slow request can outlive informer shutdown.

Capture the lifecycle context instead. The proposed ListWithContextFunc and WatchFuncWithContext fields are not available in the pinned client-go version.

Guard the login poll during unmount.

PluginDataContextProvider removes LoadData when startLoading becomes false, so LoadEventsData can unmount while /authenticated is pending. Timer-only cleanup is not sufficient: the pending fetch can later run .finally() and schedule a new timer. Its .then() or .catch() can also call tokenExpired() after unmount. Track the unmounted state before handling the response or rearming the timer.
