NE-2839: Add HAProxy version upgrade tests - #31602
Conversation
The IngressControllerMultipleHAProxyVersions feature allows selecting HAProxy versions per IngressController. During y-stream upgrades (e.g. 4.22 to 5.0), the default HAProxy version may change (2.8 to 3.2), and versions can be deprecated ahead of removal in a later release. Add HAProxyVersionUpgradeTest, a single upgrade test parameterized by Mode and registered three times to cover the scenarios that matter across an upgrade: - Unset: no HAProxyVersion set; the running version must follow whatever the new release's default becomes after the upgrade. - Default: pinned to the current default version; must retain that exact version after upgrade. - NonDefault: pinned to a supported, non-default, non-deprecated version; must retain that exact version after upgrade. Skip() avoids exercising unsafe scenarios: it skips when the IngressController API lacks the haproxyVersion field, when a pinned mode would run against a multi-hop upgrade chain (a version could be deprecated and removed between hops, with no reliable way to predict that beforehand), and when NonDefault mode has no non-deprecated non-default version available to test with. This favors skipping over risking the shared upgrade job, since a pinned version that blocks the CVO would fail every other upgrade test running alongside it. Setup creates a custom IngressController with the version implied by Mode and confirms the runtime HAProxy version matches before the upgrade starts. Test waits for the upgrade to complete, resolves the expected version (the post-upgrade default for Unset, the original pin otherwise), and validates it via both the IngressController status (EffectiveHAProxyVersion) and the HAProxy runtime socket. Also refactors multi-haproxy.go: extracts shared helpers (apiHasHAProxyVersionField, getHAProxyVersionConfig and its non-default/upgradeable version derivation) used by both the day-2 tests and the new upgrade tests, and makes teardown delete IngressControllers concurrently instead of sequentially. https://redhat.atlassian.net/browse/NE-2839 Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>

Full details: Stable And Deterministic Test NamesExplanation No changed Ginkgo test title contains run-specific data. The new upgrade tests use Full details: Test Structure And QualityExplanation PASS. The new upgrade test uses the repository's upgrade lifecycle with Setup and Teardown. Created IngressControllers are tracked and deleted with a bounded deletion wait. The shared multi-HAProxy tests use BeforeEach and AfterEach. All new polling waits have explicit timeouts, and the readiness helper propagates context. The new test assertions include diagnostic messages. The status and runtime checks validate one HAProxy version behavior through two related observations, not unrelated behaviors. No explicit test-structure failure was introduced. Full details: Microshift Test CompatibilityExplanation The pull request adds three upgrade tests in Resolution MicroShift compatibility notice: This test uses APIs or features that are not available on MicroShift. If this repository's presubmit CI does not already include MicroShift jobs, please verify your test works on MicroShift by running an additional CI job. Because this is an upgrade test, add a MicroShift skip protection, such as Full details: Single Node Openshift (Sno) Test CompatibilityExplanation The added HAProxy upgrade tests do not introduce a multi-node or HA assumption. Each test creates one IngressController with Replicas=1, uses a Private endpoint strategy, and checks version status and the runtime socket for that controller. The version-discovery code only reads OpenShift APIs and handles external topology; it does not require multiple nodes, node roles on separate hosts, failover, anti-affinity, topology spread, rescheduling, or multiple endpoints. The shared helper changes also add no such requirement. Therefore no SNO skip guard is required under this check. Full details: Topology-Aware Scheduling CompatibilityExplanation PASS: The pull request changes only upgrade and router e2e test code plus context handling. It adds no deployment manifests, operator scheduling logic, anti-affinity, topology spread constraints, PDBs, tolerations, or control-plane node selectors. The new test creates an IngressController with one replica but does not derive that count from node topology.

Added lines contain no MD5, SHA-1, DES, 3DES, RC4, Blowfish, or ECB references, no crypto package imports or primitive calls, and no secret/token comparison logic.

context.WithTimeout with an appropriate deadline, and defer the returned cancel
function. Ensure the resulting context is passed to the CRD, deployment, and
configuration reads while preserving the existing precheck behavior.

- Line 233: Update waitForIngressControllerReady and its callers to accept
context.Context, passing the caller’s ctx from the return path in the ingress
setup flow and using it to cancel or bound the readiness wait instead of relying
only on the fixed five-minute timeout.

at test/extended/router/multi-haproxy.go:317-320 so polling callbacks return
non-transient API read errors instead of converting them to (false, nil); retry
only explicitly transient errors, and never ignore error returns.

I'm a bit confused, hypershift isn't setting deprecatedVersion? Isn't that a bug? We are dropping HAProxy 2.8 in 5.1, if hypershift is not setting upgradeable=false, then upgrading a hypershift cluster from 5.0 with haproxy28 pinned would likely break (TBD i'm not sure what happens when an API value is dropped...likely just nil'ed out).
Maybe I don't understand hypershift upgrade architecture.

nvm, it's being defaulted in the CIO to 2.8 explicitly - no concern here.
But we can follow up with cleaning this up later when we drop 28 from 5.1.

simple addition for hypershift and straightforward context updates. No issue from me. I can see you are already testing hypershift and it's passing, but I will let you finish CI and apply verified. |

/override ci/prow/e2e-vsphere-ovn Automated triage: This failure appears unrelated to the PR changes. Job classification: Eligible long-running end-to-end job: Revision check: Run SHA Execution status: Tests executed. The suite ran Completed supporting jobs: Overlap assessment: The PR changes five test files for HAProxy version and router upgrade coverage; it does not modify router controller or external-certificate secret-management implementation. The failing test is in the existing external-certificate route path, which is not among the changed files. No direct overlap was found. Other external-certificate tests in this run passed, including secret recreation/RBAC and route update cases. Missing-coverage risk: Low for accepting this PR. The failure is a documented pre-existing race in the route secret-management path, with the condition remaining at Rationale: The failure signature matches the known external-certificate race rather than the PR's HAProxy version test changes. Override is appropriate for this executed-test flake. If you disagree with this assessment, rerun the current job with AI-generated. Review for accuracy. |

This is the second PR for the same functionality, it fixes HAProxy version related tests on Hypershift, previously we inferred incorrectly the namespace of the Ingress operator deployment.
