Adds omitempty and omitzero tags where appropriate to align our API with conventions set by kubernetes and openshift.

Summary by CodeRabbit

  • API Changes
    • Several empty or zero-valued fields in cluster object set and deployment data may now be omitted from JSON output, changing how unset fields are represented.
    • Cluster object set status cannot be removed once set; updates that remove it are rejected.
    • The status field uses zero-value omission behavior, while observed phase details follow empty-value omission behavior.
    • Phase object lists in cluster object sets and deployments are treated as atomic during Kubernetes patch and merge operations.

Walkthrough

JSON serialization tags changed on fields in the ClusterObjectDeployment and ClusterObjectSet API types. Phase object lists are now atomic in the API marker and CRD schemas. ClusterObjectSet validation rejects removal of status after it has been set.

Changes: Cluster object API changes

Layer / File(s) Summary
Update API serialization tags
api/v1/clusterobjectdeployment_types.go, api/v1/clusterobjectset_types.go, hack/api-lint-diff/run.sh, api/v1/clusterobjectset_types_test.go
Several fields now use omitempty. ClusterObjectSet.Status uses omitzero. Linter suppressions and the Warn policy were added, and test expectations now match required-value errors.
Declare phase object lists atomic
api/v1/clusterobjectset_types.go, helm/olmv1/base/object-controller/crd/experimental/*, manifests/experimental*.yaml
The ClusterObjectSetPhase.Objects API marker and the deployment and object-set CRD schemas declare phase object lists atomic.
Prevent removal of existing status
api/v1/clusterobjectset_types.go, applyconfigurations/api/v1/clusterobjectset.go, helm/olmv1/base/object-controller/crd/experimental/olm.operatorframework.io_clusterobjectsets.yaml, manifests/experimental*.yaml
Validation rejects updates that remove ClusterObjectSet.status when it existed in the previous object. Comments and schema descriptions document that status cannot be removed once set.

Full details: Docstring Coverage

Explanation

Docstring coverage is 0.00% which is insufficient. The required threshold is 80.00%. Docstring coverage is scoped to functions touched by this diff with cyclomatic complexity of at least 2. Documentation-only edits and deletions within surviving functions are included; unchanged diff context and fully deleted functions are excluded. Analyzed 1 functions across 5 files. (3 skipped: 3 unsupported.)

As noted in previous reviews, omitempty creates issues for these fields. Unless other actions are suggested, I propose we set //nolint:kubeapilinter on these with reasons stated.
