…rieval
The "Cluster version operator acknowledges upgrade" check waited only for
status.observedGeneration to catch up, within a fixed per-platform timeout.
The CVO advances observedGeneration only after the release payload has been
retrieved, verified, and accepted, so a slow release-image retrieval can blow
the timeout and fail the test even though the CVO is legitimately making
progress.
Make the wait tolerate a slow-but-progressing retrieval and fail fast only on a
genuine, non-recoverable payload rejection:
- succeed as soon as observedGeneration catches up (payload accepted);
- fail fast only when the CVO terminally rejects the payload -- ReleaseAccepted=False
with a reason retrying cannot fix (LoadPayload, VerifyPayloadVersion, or
PreconditionChecks);
- otherwise keep waiting up to a bounded hard cap. A RetrievePayload failure is
the CVO retrying a slow, unreachable, or transiently-erroring pull (including a
registry auth failure), which frequently succeeds on a later attempt, so it is
not treated as fatal; a pull that never succeeds still fails the test when the
cap elapses.
The previous revision failed fast on any ReleaseAccepted=False, but the CVO
reports ReleaseAccepted=False with reason "RetrievePayload" after each failed
retrieval attempt of a slow-but-eventually-successful pull, so that check would
still have failed the very runs this fixes. It also failed at the short
per-platform timeout when no target-matched ReleaseAccepted condition was yet
visible, but the CVO does not reliably publish its "retrieving" condition until
the first attempt completes, so a legitimately slow first pull would trip that
check too. Both are removed: the wait is now bounded solely by the hard cap and
fail-fast is reserved for terminal rejections. The 20m cap aligns with the
maximum acknowledgement wait in openshift#31654.
The fail-fast error surfaces only the ReleaseAccepted condition reason (a fixed
CVO step identifier); the raw condition message is omitted because it echoes the
requested image and retrieval error, which can carry internal registry
hostnames or other sensitive data into JUnit output and cluster events.

What / Why
Fixes OCPBUGS-115163: the
[sig-cluster-lifecycle] Cluster version operator acknowledges upgradecheck can time out while the CVO is legitimately retrieving a slow release payload, producing a false acknowledgement failure.The check waited only for
status.observedGenerationto catch up, within a fixed per-platform timeout (2m default / 4m OpenStack / 10m bare metal). The CVO advancesobservedGenerationonly after the release payload has been retrieved, verified, and accepted, so a slow release-image pull outlasts the fixed window even while the CVO is making progress, and the test fails.Approach
Keep acknowledgement gated on the payload actually being accepted (
observedGenerationcatching up), but make the wait tolerate a slow-but-progressing retrieval and fail fast only on a terminal payload rejection — one that retrying cannot fix. The decision keys on the CVOReleaseAcceptedClusterVersion condition, whoseReasonis the CVO's payload-load step.ReleaseAccepted=Falsecases and why some are terminalRetrievePayloadLoadPayloadVerifyPayloadVersionPreconditionChecksWhy
RetrievePayloadis not terminal. The CVO reportsReleaseAccepted=False, reason=RetrievePayloadafter each failed retrieval attempt of a pull that is merely slow (theversion-*pod hits its 2-minuteActiveDeadlineSeconds, or the build-farm registry is temporarily slow/unreachable). Such pulls routinely succeed on a subsequent attempt — the OCPBUGS-115163 failures are exactly this shape (GCP/Azure/libvirt runs that time out a few times, thenPayloadLoadedfires and the cluster upgrades). Failing fast here would fail the very runs this PR targets. A persistent registry-auth failure (invalid username/password) surfaces under this same reason and is indistinguishable from a slow pull by reason alone, so it is treated identically (keep waiting) and correctly fails when the cap elapses — bounded, never a false pass.Why the others are terminal.
LoadPayload,VerifyPayloadVersion, andPreconditionChecksdescribe a payload or cluster state that retrying cannot fix; waiting them out to the cap only wastes time, so we fail fast — surfacing only the reason (a fixed CVO step identifier), never the raw condition message, which can carry internal registry hostnames.Force: truenuance (this test forces the update): the CVO bypasses signature verification and downgrades precondition failures to warnings when forced, so in practice onlyLoadPayloadandVerifyPayloadVersioncan actually fire here.PreconditionChecksis kept in the terminal set defensively (correct if the test ever runs unforced).Behavior
observedGenerationcatches up (payload accepted) — unchanged success criterion.ReleaseAccepted=False(LoadPayload/VerifyPayloadVersion/PreconditionChecks), surfacing only the condition reason.maxCVOUpdateAckTimeout(20m, matching the maximum acknowledgement wait in OCPBUGS-115163: test/e2e/upgrade/upgrade: 20m fatal observation for update-ack #31654). A retrieval that never succeeds, or a request the CVO never picks up, still fails when the cap elapses.The failure message uses the
Timed outprefix only when the hard-cap deadline actually expires; a terminal rejection or a desired-update conflict surfaced by the poll uses a neutralFailed while waiting for cluster to acknowledge upgradeprefix.Why the earlier revisions of this PR were changed
ReleaseAccepted=False. But the CVO stampsReleaseAccepted=False, reason=RetrievePayloadon each failed attempt of a slow-but-eventually-successful pull, so that check would still have failed the very runs this fixes.ReleaseAccepted=Unknown) condition until the first attempt completes, so a legitimately slow first pull shows no target-matched condition at the short timeout and would trip that check.Both checks are removed: the wait is bounded solely by the hard cap and fail-fast is reserved for terminal rejections.
Supersedes #31583 (which accepted a "retrieval started" signal as acknowledgement — rejected because it would let a real download/verification failure pass with no bounded place left to catch it). Complementary to #31654 (same test; shared 20m maximum wait). The underlying retrieval slowness is also being addressed upstream in openshift/cluster-version-operator#1361; this change hardens the test itself so it does not raise false failures regardless.
Testing
Local, on the changed package:
go test ./test/e2e/upgrade/— table-driven unit tests pass:releaseAcceptedForTarget— in-progress match, failure match, stale/other-image ignored (incl. version-matches-but-image-differs), version-only match/non-match.isTerminalReleaseAcceptedFailure— terminal reasons vs retriableRetrievePayloadvs non-Falseconditions.ackProgress— success on generation catch-up, keep-waiting on retrieving/retrieval-failure, fail-fast on terminal rejection, and acceptance winning over a stale terminal condition.go vet ./test/e2e/upgrade/— clean.gofmt -l— clean.go build ./test/e2e/upgrade/— compiles. (Fullopenshift-testsbinary build covered by CI.)Validated against real recent CI runs: slow-but-successful pulls (e.g. libvirt
2099777836721115136, request→PayloadLoaded ~2m26s) now pass; persistent metal registry-auth failures (e.g.2100551312939683840) fail bounded at the cap rather than being conflated with slow pulls.Summary by CodeRabbit
