Summary

Consolidates applydesire/deletedesire/readdesire's previously-duplicated envtest suites into a single test/integration package with shared fixtures, and finishes unifying all three controllers' RESTMapper-miss handling to a consistent reset-and-retry-once policy.

  • Move the three controllers' envtest_test.go files into test/integration, split across one file per controller plus a shared envtest_test.go (TestMain) and helpers_test.go
  • Extract shared identity/manifest-content/CRD-install/condition/wait helpers used across all three controllers' tests, replacing near-identical copies
  • HYPERFLEET-1429

Test Plan

  • Unit tests added/updated
  • make lint passes
  • make test-envtest passes

📝 Walkthrough

Summary by CodeRabbit

  • Improvements

    • Improved automatic discovery and recovery for newly installed resource types across apply, read, and delete operations.
    • Improved handling of cluster-scoped resources and manifests that include namespaces.
    • Strengthened coordination across apply, read, and delete workflows to prevent deleted resources from reappearing.
    • Improved read reliability when resource synchronization is delayed or interrupted.
    • Controllers now reconcile immediately on startup before periodic retries.
  • Bug Fixes

    • Repeated apply operations remain no-ops when no changes are needed.
    • Apply operations can reclaim fields contested by other managers.
    • Delete operations correctly handle missing resources and resources blocked by finalizers.
    • Invalid manifests now report Kubernetes API validation errors.

Walkthrough

The change adds a shared envtest harness and helpers for integration tests. It adds ApplyDesire, ReadDesire, DeleteDesire, and combined lifecycle coverage for namespaced, cluster-scoped, and custom resources. Tests cover finalizers, repeated apply, server-side apply ownership, informer shutdown, API validation errors, and CRD discovery refresh. ApplyDesire and ReadDesire retry stale REST mapper lookups once. Informer startup now enqueues desires after synchronization timeout. Former controller-local envtest files were removed.

Estimated code review effort: 4 (Complex) | ~45 minutes

Merge Risk: ⚪ Minimal · up to cd049

This PR consolidates integration tests and standardizes controller retry behavior; no actionable merge-blocking risk remains based on the supplied evidence.

Explanation

Docstring coverage is 77.78% which is insufficient. The required threshold is 80.00%. Docstring coverage is scoped to functions touched by this diff. Analyzed 36 functions across 12 files. (1 skipped: 1 unsupported.)

Full details: Sec-02: Secrets In Log Output

Explanation

No failure condition found. The changed non-test, non-example production files add no token, password, credential, or secret fields or interpolations to logging statements. The only added log calls are in informer_manager.go and contain namespace, name, and timeout fields. No added fmt.Print*, logr, or zap logging calls were found. No CWE/CVE is implicated by this check.

Full details: No Hardcoded Secrets

Explanation

No hardcoded secret was introduced. The PR-added lines contain no API keys, passwords, tokens, credentials, private-key blocks, credential-bearing URLs, or sensitive-name assignments to string literals. The only long base64-like additions are Go module integrity hashes in go.sum, not configuration secrets. The other matches are Kubernetes API identifiers, log text, documentation, or test fixtures, which the check excludes.

Full details: No Weak Cryptography

Explanation

No banned cryptographic primitive or custom cryptographic implementation was introduced by commit cd0497e. The changed Go files add no crypto imports, and repository source contains no references to crypto/md5, crypto/des, crypto/rc4, SHA-1, ECB, HMAC comparison, or ConstantTimeCompare. The dependency changes add goleak and update Kubernetes modules only. No CWE-327 finding applies.

Full details: No Injection Vectors

Explanation

PASS. The changed production code adds RESTMapper reset/retry logic and informer lifecycle handling. It introduces no SQL query construction (CWE-89), exec.Command/exec.CommandContext use (CWE-78), template.HTML wrapping (CWE-79), or yaml.Unmarshal/NewDecoder use (CWE-502). The changed fmt.Sprintf calls only format diagnostic status messages; the other occurrence is in a test file, which this check excludes. Dependency updates add no injection sink.

Full details: No Privileged Containers

Explanation

PASS — The pull request changes Go code, tests, documentation, and Go dependencies. It does not modify Dockerfiles, Helm templates, or Kubernetes/OpenShift manifests. The repository scan found no privileged: true, hostPID, hostNetwork, hostIPC, SYS_ADMIN, allowPrivilegeEscalation: true, runAsUser: 0, or USER root. The new envtest files are test code, which this check excludes. No CWE or CVE applies.

Full details: No Pii Or Sensitive Data In Logs

Explanation

No changed logging statement matches the stated sensitive-data conditions. The new readdesire logs emit only validated Kubernetes namespace, name, and a timeout; they do not emit email addresses, SSNs, credit-card data, session IDs, request/response bodies, or credentials. The new fmt.Fprintf calls are envtest-only diagnostics for startup and teardown errors. Equivalent envtest stderr diagnostics already existed in the deleted controller test files, so their relocation does not introduce new exposure. No CWE/CVE applies.

94-95: 📐 Maintainability & Code Quality | 🔵 Trivial | ⚡ Quick win

Capture the Run error instead of discarding it.

_ = c.Run(ctx) drops the controller error. If Run returns early with a real failure, the test does not report it. It fails 10 seconds later inside waitForReason with an unrelated timeout message. This pattern repeats at Lines 191-192, 245-251, and 292-293, and in test/integration/lifecycle_test.go Lines 59 and 142.

Store the error and assert it after cancellation, or log it from the goroutine.

♻️ Proposed change
-	c := readdesire.NewController(store, store, envDynamicClient, envRESTMapper, testManagementCluster, 100*time.Millisecond)
-	go func() { _ = c.Run(ctx) }()
+	c := readdesire.NewController(store, store, envDynamicClient, envRESTMapper, testManagementCluster, 100*time.Millisecond)
+	go func() {
+		if err := c.Run(ctx); err != nil && !errors.Is(err, context.Canceled) {
+			t.Errorf("readdesire Run: %v", err)
+		}
+	}()

Note: t.Errorf from a goroutine is safe, but it must not run after the test returns. Gate it with a done channel as TestEnvtest_ReadDesire_GoroutinesDoNotLeakOnShutdown already does.

Wait for all controller goroutines before measuring the baseline.

Several integration tests start Run in a goroutine and register only t.Cleanup(cancel). Their informer and reflector goroutines can still run when this test records runtime.NumGoroutine(). Retain a done channel and wait for Run to return in each test cleanup, or use a configured goleak check that ignores known envtest goroutines.

Remove the blocking finalizer during cleanup.

The test creates test-pod-finalizer with test.finalizer/block-deletion and never removes it. All three suites now share one apiserver process, so the pod stays in a terminating state and blocks deletion of namespace test-ns-finalizers for the rest of the run. Register a t.Cleanup that clears Finalizers and reports any error.

Sample the goroutine baseline after the shared harness is quiet.

baseline is read at line 230 while goroutines from previously executed tests in this package may still be exiting. That inflates baseline and makes the leak assertion pass even when informer goroutines leak. The check then reports a false pass, which is the failure mode that matters for a leak test.

Poll runtime.NumGoroutine() until it stabilizes before you record baseline.

253-255: 🩺 Stability & Availability | 🟡 Minor | ⚡ Quick win

Register cancel with t.Cleanup — the previous fix did not land. cancel is only called at Line 268. waitForReason at Line 265 can call t.Fatalf, which ends the test goroutine before Line 268. The readdesire.Controller then keeps its worker pool and five informers running against the shared apiserver for the remainder of the package run. Every later test in this process inherits that watch traffic. This test is the goroutine-leak assertion, so an unstopped controller here corrupts the baseline for nothing.

Lines 85, 187, and 292 in this same file already use t.Cleanup(cancel). Keep the explicit cancel() at Line 268 so the shutdown timing under test is unchanged; t.Cleanup only covers the failure path.

62-62: 📐 Maintainability & Code Quality | 🔵 Trivial | ⚡ Quick win

Capture the Controller.Run error instead of discarding it. _ = readC.Run(ctx) swallows the only signal that the controller failed to start. If Run returns early with an error, the test does not report it. It instead fails 10 seconds later inside waitForReason with a status-timeout message that names the wrong cause. This pattern repeats at Line 147 in this file and at Lines 96, 198, and 303 of test/integration/readdesire_controller_test.go; fix it once with a shared helper.

Ignoring a returned error is only acceptable as intentional degradation with a comment, per the HyperFleet error-handling checks.

The ticket asks for a goroutine-count assertion after "rapid create and delete churn," but this test creates desires once and then shuts down. Consider adding a loop that repeatedly creates and deletes desires while the controller is running, then checking the goroutine count, to cover the informer start/stop cycle leak risk.

There's no test for applying updated content. The no-op test proves unchanged content doesn't mutate the object, but nothing verifies that changing a desire's KubeContent and reconciling again actually updates the live object.

Reset() in resolveGVR is still unrate-limited.

pollOnce calls resolveGVR for every ReadDesire on every pollInterval tick. A permanently unresolvable resource returns NoMatchError each time, so c.mapper.Reset() invalidates the shared discovery cache on every tick for every such desire. With a 50-100ms poll interval this becomes continuous discovery traffic against the apiserver (CWE-400). Gate the reset behind a minimum interval or a per-identity one-shot.

Extract the shared three-controller setup.

Both tests repeat the same block: create the store, build three identities, create the ApplyDesire and ReadDesire, construct three controllers with the same arguments, and start three goroutines. Only the identity constructor and the manifest builder differ. Extract a helper that returns the store and the three identities, then keep the divergent assertions in each test.

Release the timer when stopCh wins the race.

time.After keeps its runtime timer armed for the full timeout even after stopCh closes and this goroutine returns. Each informer start arms one 30-second timer, so create/delete churn accumulates dead timers for up to 30 seconds. Use time.NewTimer with a deferred Stop.

Downgrade both slog.Error calls to match the actual severity.

The teardown branch at Line 193 fires on a normal shutdown of an informer that has not synced yet. That is expected during a clean stop, not a failure. The timeout branch at Line 206 is documented degradation: the code enqueues the key, the informer keeps retrying, and AddFunc corrects the status later. Both are slog.Warn cases. Error-level logs on routine shutdown paths pollute alerting.

Clean up the namespaces and the finalizer-blocked Pod.

TestEnvtest_DeleteDesire_SimpleCases leaves test-ns-simple in the shared API server. TestEnvtest_DeleteDesire_WaitsForFinalizers leaves both test-ns-finalizers and its terminating Pod. A repeated envtest run can then fail on Create with AlreadyExists.

Register cleanup for each Namespace. For the finalizer case, remove the test finalizer, wait for Pod deletion, then delete and wait for Namespace deletion.

As per path instructions, “MUST clean up on ALL paths including early returns.”

Update TestEnvtest_DeleteDesire_SimpleCases and
TestEnvtest_DeleteDesire_WaitsForFinalizers to register cleanup for every
created Namespace on all paths, including early returns. For the finalizer case,
remove the test finalizer from the Pod, wait until the Pod is deleted, then
delete the Namespace and wait for its deletion. Ensure cleanup runs before each
test exits.

…st/integration

Consolidates applydesire/deletedesire/readdesire's previously-duplicated
envtest suites into a single test/integration package with shared fixtures,
and finishes unifying all three controllers' RESTMapper-miss handling to a
consistent reset-and-retry-once policy.

- Move the three controllers' envtest_test.go files into test/integration,
  split across one file per controller plus a shared envtest_test.go
  (TestMain) and helpers_test.go
- Extract shared identity/manifest-content/CRD-install/condition/wait
  helpers used across all three controllers' tests, replacing near-identical
  copies
