OCPEDGE-3039: Fixes TNF PHC flaky tests

[vimauro]

Summary by CodeRabbit

• Tests
  • Improved etcd disruption recovery validation by clearing stale failure status before each scenario.
  • Extended simulated network disruptions to better align with fencing timing.
  • Updated recovery checks to confirm degraded health clears after network restoration.
  • Added informational validation for offline events on the node actually fenced during recovery.
  • Adjusted event validation to account for timing differences and cases where status events may not be captured.

Walkthrough

The edge topology tests now clear stale etcd failure actions before disruptions and strengthen network recovery validation. The network disruption lasts beyond the fencing-priority delay and checks recovery for the node that Pacemaker fenced.

Changes

Edge topology validation

Layer / File(s)	Summary
Etcd failure baseline and evidence test/extended/edge_topologies/tnf_etcd_disruption.go	The tests run pcs resource cleanup, poll pcs status until stale etcd failures are absent, and validate later failures against the current disruption.
Network disruption recovery validation test/extended/edge_topologies/tnf_recovery.go	The test uses a 25-second disruption, records disruptionStart, waits for PacemakerHealthCheckDegraded to clear, and checks PacemakerNodeOffline for the learner node that Pacemaker fenced.

Estimated code review effort: 3 (Moderate) | ~20 minutes

Merge Risk: ⚪ Minimal · up to 31f3e

This change improves edge topology disruption-test isolation and recovery validation. No concrete merge-blocking risk remains.

Full details: Stable And Deterministic Test Names

Explanation

No failure condition was introduced. The PR changes only the two candidate Go files, and the complete Ginkgo title-call set is identical between HEAD^^ and HEAD: 6 g.It titles in tnf_etcd_disruption.go and 10 in tnf_recovery.go. All titles are static strings. New dynamic node values occur in g.By body steps and logging, not in It, Describe, Context, or When titles.

Full details: Test Structure And Quality

Explanation

No explicit test-structure failure was introduced. The new Eventually calls in clearEtcdFailedActionsBaseline and both etcd failure checks use finite timeouts and polling intervals. The new health-condition and event waits also use bounded timeouts. Added assertions include diagnostic messages. The affected suites already use BeforeEach, AfterEach, and DeferCleanup; the PR adds no uncleaned cluster-scoped resource. The recovery and failure checks remain related to each disruption behavior. Existing patterns use the same helper and wait structure. The unchanged disruption-pod lifecycle and older assertions without messages are pre-existing and do not establish pull-request causality.

Full details: Microshift Test Compatibility

Explanation

No MicroShift compatibility failure is introduced. The full PR diff adds no new g.It, g.Describe, g.Context, or g.When declarations. It only changes existing test bodies and adds a helper. All affected tests are inside Describe blocks tagged [apigroup:config.openshift.io], which is an explicitly supported MicroShift skip mechanism for the unavailable API group.

Full details: Single Node Openshift (Sno) Test Compatibility

Explanation

No new Ginkgo test declarations were added. The PR keeps the existing Describe and It declarations unchanged and only modifies existing two-node tests plus helper logic. The multi-node assumptions were pre-existing, so this check does not identify a new SNO compatibility issue.

Full details: Topology-Aware Scheduling Compatibility

Explanation

PASS — The PR changes only two Go test files: test/extended/edge_topologies/tnf_etcd_disruption.go and test/extended/edge_topologies/tnf_recovery.go. The diff adds test polling, cleanup, timing, and event-check logic. It does not add or modify deployment manifests, operator code, controllers, replicas, affinity, topology spread, selectors, tolerations, or PDBs. The topology-aware scheduling check is therefore not applicable.

Full details: Ote Binary Stdout Contract

Explanation

The PR changes only two Ginkgo test files. The added framework.Logf calls are inside g.It bodies and inside their Eventually callbacks, where test output is intercepted. The added clearEtcdFailedActionsBaseline function only runs remote commands and constructs errors; it does not write to process stdout. The diff adds no fmt.Print*, log.Print*, klog, init, TestMain, suite setup, or RunSpecs output. The shell echo strings are remote command scripts, not writes by the OTE binary process.

Full details: Ipv6 And Disconnected Network Test Compatibility

Explanation

PASS. The PR adds no new Ginkgo declarations; it modifies existing disruption tests. The changed code adds PCS cleanup/status polling, timing, and cluster-internal Pacemaker event checks. It adds no hardcoded IPv4 address, IPv4-only parsing, public URL, registry pull, or external service. The existing network helper selects the node internal address dynamically and uses ip6tables when net.ParseIP(...).To4() is nil.

Full details: No-Weak-Crypto

Explanation

PASS: The PR changes only TNF etcd and network-disruption test logic. The full PR diff adds no MD5, SHA1, DES, 3DES, RC4, Blowfish, or ECB usage. It adds no cryptographic implementation and no secret or token comparison. The changed code uses Pacemaker status cleanup, event checks, and timing changes only.

Full details: Container-Privileges

Explanation

PASS. The pull request changes only two Go test files. The diff adds no container or Kubernetes manifest fields for privileged, hostPID, hostNetwork, hostIPC, SYS_ADMIN, allowPrivilegeEscalation, or root execution. The added sudo pcs commands run existing node-side test commands and do not introduce a manifest privilege setting.

Full details: No-Sensitive-Data-In-Logs

Explanation

The pull request adds sensitive logging. In tnf_etcd_disruption.go, new framework.Logf calls log raw sudo pcs status output and the raw Failed Resource Actions section at lines 632, 641, 690, and 699. ExtractPcsFailedActions returns the output from the section marker through the end, which can include Pacemaker node names and other internal hostnames. New error messages also embed that raw section at lines 352, 636, and 694, so a failed assertion can expose it. The PR also adds a network-test call that activates existing event logging with learnerNode.Name in tnf_recovery.go line 256.

Resolution

Do not log raw pcs status, failed-action sections, or command errors that contain them. Parse the result and log only a fixed status or a sanitized action type without node names or other cluster identifiers. Replace the raw failedSection text in retry errors with a generic message. Remove node names from the newly activated Pacemaker event log, or use a non-identifying label.
