OCPBUGS-99266: add CRD-before-CR payload ordering test - #1464
Conversation
Guard the payload-wide invariant that a CustomResource is never applied before the CustomResourceDefinition that defines it. Under the CVO's strict UpdatingPayload ordering, a CR whose run-level is below its CRD's deadlocks the update (OCPBUGS-99266, the empty CRIOCredentialProviderConfig CR at run-level 0000_05 with its CRD at 0000_10). The test classifies each CR/CRD pair as SAFE, NONBLOCKING (same run-level; self-heals via re-apply), or BLOCKING (CR run-level below CRD; deadlocks) using the same run-level/component parsing the CVO applies. TestCheckCRDOrdering_Fixtures covers the classifier hermetically; TestPayloadCRDOrdering walks a real extracted payload when CVO_PAYLOAD_MANIFEST_DIR is set (skipped otherwise, so the default unit run stays hermetic) and is intended to be wired into CI against an oc-adm-release-extract directory. Both BLOCKING and NONBLOCKING pairs fail the payload check: BLOCKING as deadlocks, NONBLOCKING to stop new same-run-level ordering hazards from entering the payload. The long-standing same-run-level pairs already shipping (captured from the 4.22.9 payload) are grandfathered in knownAcceptedNonBlocking, and the one works-by-accident cross-run-level pair (ServiceMonitor, whose CRD pre-exists from prior releases) in knownAcceptedBlocking. Both allowlists are documented and should shrink as the owning repos are cleaned up.

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win
Handle CRD and CR in the same manifest file.
classifyPair requires crd.filename < cr.filename for the same-component SAFE case. A single manifest file that contains the CRD document followed by its CR document produces equal filenames, so the pair is classified NONBLOCKING. The CVO applies documents from one file serially in document order, so that layout is safe. TestPayloadCRDOrdering would fail a valid new manifest that bundles a CRD and its CR.
Record the document index in orderingManifest and use it as the tiebreaker when filenames are equal.
♻️ Proposed change
type orderingManifest struct {
filename string
+ docIndex int // position of this document within its file
runLevel int // parsed from the 0000_NN_ prefix; -1 if unparseable
component string // the NAME in 0000_NN_NAME_; "" if unparseable default: // same run-level
// Same component applies serially in filename byte-order (Go string
// comparison is byte-wise, matching the CVO's C-locale ordering).

+ // Documents within one file apply in document order.
+ return severitySafe
+ }
+ if crd.component == cr.component && crd.filename < cr.filename {
return severitySafe
}The docIndex must be set in parseOrderingManifests from the loop index i.

🩺 Stability & Availability | 🟡 Minor | ⚡ Quick win
Do not abort the payload scan on one unparseable YAML file.
parseOrderingManifests calls t.Fatalf on any parse error, and the walk feeds it every .yaml/.yml file under the directory. An extracted payload directory also contains YAML that is not a Kubernetes manifest, and CVO manifests contain Go template placeholders that are not rendered here. One such file stops the whole check, so a real blocking violation elsewhere is never reported.
Parse per file without t.Fatalf, log the skipped file, and keep scanning.

What
Add a regression test in
pkg/payloadthat enforces a payload-wide invariant: a CustomResource must never be applied before the CustomResourceDefinition that defines it.Two tests:
TestCheckCRDOrdering_Fixtures— hermetic, in-memory cases covering the classifier (SAFE / NONBLOCKING / BLOCKING). Always runs.TestPayloadCRDOrdering— walks a real extracted payload whenCVO_PAYLOAD_MANIFEST_DIRpoints at anoc adm release extractdirectory; skipped otherwise, so the default unit run stays hermetic. Intended to be wired into CI (e.g. an openshift/release step that extracts the payload).Why
Under the CVO's strict
UpdatingPayloadordering, the0000_NNrun-level is a barrier — the CVO will not advance to a higher run-level until the current one completes. A CR whose run-level is below its CRD's therefore deadlocks the update, because the CR's run-level can never finish (its CRD is created at a higher, never-reached run-level). This is exactly OCPBUGS-99266: the emptyCRIOCredentialProviderConfigCR shipped at0000_05while its CRD shipped at0000_10, and once the feature gate went to Default the deadlock became reachable on self-managed-HA upgrades.The openshift/api fix (openshift/api#3011) moves that CR and adds a source-repo unit test, but that test only sees openshift/api's own manifests. Most CRs are shipped by individual operator repos, and only a check over the assembled payload can catch a CR/CRD ordering deadlock introduced anywhere across the ~100 contributing repos. That is what this test provides.
How
The classifier reuses the CVO's own run-level/component parsing (
reMatchPattern) and models the real apply semantics:bootstrap-required, or at a lower run-level → SAFE.TestPayloadCRDOrderingfails on both BLOCKING and NONBLOCKING pairs — BLOCKING as deadlocks, NONBLOCKING to stop new same-run-level ordering hazards from entering the payload. Two documented allowlists grandfather what already ships:knownAcceptedBlocking— the one works-by-accident cross-run-level pair (ServiceMonitor, whosemonitoring.coreos.comCRD pre-exists from every prior release).knownAcceptedNonBlocking— the 26 long-standing same-run-level pairs (monitoring CRs, and operator/config CRs whose CRD is generated by openshift/api at the same run-level), captured from the 4.22.9 payload. These are cross-repo and self-healing; the allowlist should shrink as the owning repos are cleaned up.Test
Against the (pre-fix) 4.22.9 payload the test correctly fails on exactly one pair — the
CRIOCredentialProviderConfigdeadlock — and passes clean once that fix ships.🤖 Generated with Claude Code
