⏺ API Review Report for PR #2510

  ❌ REVIEW FAILED - Issues Found

  The API review has identified several critical issues that must be addressed before this PR can be approved.

  🚨 Linting Errors (CRITICAL)

  The make lint command failed with kubeapilinter errors:

  +35: Spec field validation issue
  Current (problematic) code:
  Spec InternalReleaseImageSpec `json:"spec,omitzero"`

  Suggested change:
  - Spec InternalReleaseImageSpec `json:"spec,omitzero"`
  + Spec *InternalReleaseImageSpec `json:"spec,omitzero"`

  Explanation: The field has a valid zero value ({}) but incomplete validation. Since it's marked as +required, it should be a pointer to allow the zero value to be set, or the validation should be completed to make the zero value invalid.

  +39: Status field validation issue
  Current (problematic) code:
  Status InternalReleaseImageStatus `json:"status"`

  Suggested change:
  - Status InternalReleaseImageStatus `json:"status"`
  + Status *InternalReleaseImageStatus `json:"status"`

  Explanation: The field has a valid zero value ({}) but incomplete validation. Since status subresources typically allow empty initial states, this should be a pointer to allow the zero value to be set.

  📚 Documentation Issues (MODERATE)

  +48: Missing optional field behavior documentation
  Current (problematic) code:
  // conditions represent the observations of an internal release image current state.
  // +listType=map
  // +listMapKey=type
  // +kubebuilder:validation:MaxItems=20
  // +optional
  Conditions []metav1.Condition `json:"conditions,omitempty"`

  Suggested change:
  - // conditions represent the observations of an internal release image current state.
  + // conditions represent the observations of an internal release image current state.
  + // When omitted, the resource has no status conditions to report.

  Explanation: Optional fields must explain what happens when they are omitted. The field comment should state the behavior when the field is not present.

  +57: Missing optional field behavior documentation
  Current (problematic) code:
  // availableReleases is a list of release bundle identifiers currently detected
  // from the attached ISO.
  // +listType=map
  // +listMapKey=name
  // +kubebuilder:validation:MinItems=1
  // +kubebuilder:validation:MaxItems=64
  // +optional
  AvailableReleases []InternalReleaseImageRef `json:"availableReleases,omitempty"`

  Suggested change:
  - // availableReleases is a list of release bundle identifiers currently detected
  - // from the attached ISO.
  + // availableReleases is a list of release bundle identifiers currently detected
  + // from the attached ISO.
  + // When omitted or empty, no release bundles have been detected from the attached ISO.

  Explanation: Optional fields must explain what happens when they are omitted. Also, the validation constraints (MinItems=1, MaxItems=64) should be documented.

  +66: Missing optional field behavior documentation
  Current (problematic) code:
  // releases is a list of the currently managed release bundles.
  // +listType=map
  // +listMapKey=name
  // +kubebuilder:validation:MinItems=1
  // +kubebuilder:validation:MaxItems=64
  // +optional
  Releases []InternalReleaseImageRef `json:"releases,omitempty"`

  Suggested change:
  - // releases is a list of the currently managed release bundles.
  + // releases is a list of the currently managed release bundles.
  + // When omitted or empty, no release bundles are currently being managed.

  Explanation: Optional fields must explain what happens when they are omitted. Also, the validation constraints (MinItems=1, MaxItems=64) should be documented.

  +78: Missing optional field behavior documentation
  Current (problematic) code:
  // releases is a list of release bundle identifiers that the user wants to
  // add/remove to/from the control plane nodes.
  // +optional
  // +kubebuilder:validation:MinItems=1
  // +kubebuilder:validation:MaxItems=20
  // +listType=map
  // +listMapKey=name
  Releases []InternalReleaseImageRef `json:"releases,omitempty"`

  Suggested change:
  - // releases is a list of release bundle identifiers that the user wants to
  - // add/remove to/from the control plane nodes.
  + // releases is a list of release bundle identifiers that the user wants to
  + // add/remove to/from the control plane nodes.
  + // When omitted or empty, no release bundle operations are requested.
  + // Must contain between 1 and 20 items when specified.

  Explanation: Optional fields must explain what happens when they are omitted. The validation constraints (MinItems=1, MaxItems=20) must also be documented in the field comment.

  +93: Missing optional field behavior documentation
  Current (problematic) code:
  // image is an OCP release imaged referenced by digest.
  // The format of the image pull spec is: host[:port][/namespace]/name@sha256:<digest>,
  // where the digest must be 64 characters long, and consist only of lowercase hexadecimal characters, a-f and 0-9.
  // The length of the whole spec must be between 1 to 447 characters.
  // +optional
  Image machineosconfig.ImageDigestFormat `json:"image,omitempty"`

  Suggested change:
  - // image is an OCP release imaged referenced by digest.
  - // The format of the image pull spec is: host[:port][/namespace]/name@sha256:<digest>,
  - // where the digest must be 64 characters long, and consist only of lowercase hexadecimal characters, a-f and 0-9.
  - // The length of the whole spec must be between 1 to 447 characters.
  + // image is an OCP release imaged referenced by digest.
  + // The format of the image pull spec is: host[:port][/namespace]/name@sha256:<digest>,
  + // where the digest must be 64 characters long, and consist only of lowercase hexadecimal characters, a-f and 0-9.
  + // The length of the whole spec must be between 1 to 447 characters.
  + // When omitted, the release bundle identifier refers to the name only without an associated image.

  Explanation: Optional fields must explain what happens when they are omitted. This field needs to clarify what happens when no image is specified for a release bundle.

  ✅ Positive Findings

  - API Structure: Well-organized with appropriate separation between spec and status
  - Feature Gate: Properly gated behind NoRegistryClusterOperations feature gate
  - Validation Rules: Comprehensive validation using kubebuilder markers and CEL expressions
  - Generated Files: All required generated files (deepcopy, CRDs, swagger docs) are present and properly updated
  - List Support: Proper list type and map key annotations for array fields
  - Compatibility: Correctly marked as compatibility level 4 for alpha API

  📋 Action Required

  1. CRITICAL: Fix the linting errors by addressing the pointer vs value type issues for Spec and Status fields
  2. REQUIRED: Add proper documentation for all optional fields explaining behavior when omitted
  3. RECOMMENDED: Document validation constraints in field comments for better developer experience

  The PR cannot be approved until the critical linting errors are resolved and all optional fields have proper behavior documentation.

⏺ You're absolutely right. Looking more carefully at the validation markers, I missed several undocumented validation markers:

  Additional Undocumented Validation Markers I Missed:

  +47: MaxItems validation not documented
  // +kubebuilder:validation:MaxItems=20
  The comment doesn't mention the maximum of 20 items for conditions.

  +55-56: MinItems and MaxItems validation not documented
  // +kubebuilder:validation:MinItems=1
  // +kubebuilder:validation:MaxItems=64
  The comment doesn't mention the 1-64 item range for availableReleases.

  +63-64: MinItems and MaxItems validation not documented
  // +kubebuilder:validation:MinItems=1  
  // +kubebuilder:validation:MaxItems=64
  The comment doesn't mention the 1-64 item range for releases in status.

  +84-85: MinLength and MaxLength validation not documented
  // +kubebuilder:validation:MinLength=1
  // +kubebuilder:validation:MaxLength=64
  The comment doesn't mention the 1-64 character length constraints for the name field.

  So no, my original review was incomplete. I identified the optional field behavior issues but missed documenting several validation constraints that should be included in the field comments according to OpenShift API documentation standards.
