Summary of Changes

Hello @googs1025, I'm Gemini Code Assist¹! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request significantly enhances the status reporting capabilities of the RoleSet custom resource by introducing a new Progressing condition. This addition provides a more detailed view of the RoleSet's lifecycle, allowing users and automated systems to track its transient states as underlying roles are being updated or scaled, thereby improving observability and operational insight.

Highlights

• New Condition Type: Introduced RoleSetProgressing as a new ConditionType in the API definition to provide more granular status updates during resource reconciliation.
• Enhanced Condition Reasons: Defined a set of new constants for Ready, Progressing, and ReplicaFailure condition reasons (e.g., RoleSetReasonRolesReady, RoleSetReasonRolesProgressing), offering more specific context for status messages.
• Progressing Condition Logic: Implemented logic within the RoleSet controller's status calculation to determine if a RoleSet is Progressing. This state is now set when roles have unready replicas or are in the process of updating, based on ReadyReplicas and UpdatedReadyReplicas.
• Status Update Refinement: Updated existing RoleSetReady and RoleSetReplicaFailure condition setting to utilize the newly defined reason constants, improving consistency and clarity across all status conditions.

Code Review

This pull request introduces a Progressing condition to the RoleSet status, which is a valuable addition for observing the state of a RoleSet during updates. The implementation is mostly correct, but I've identified a few areas for improvement in the sync.go file to enhance code clarity, correctness, and consistency in user-facing messages. My suggestions include simplifying a redundant condition, making status messages more consistent and grammatically correct, and refining the logic for state transitions of the new Progressing condition.

[gemini-code-assist]

The condition to check if a role is progressing is partially redundant. The third part of the || condition, (roleStatus.UpdatedReplicas > 0 && roleStatus.UpdatedReadyReplicas < roleStatus.UpdatedReplicas), is already covered by the second part, roleStatus.UpdatedReadyReplicas < roleStatus.UpdatedReplicas.

If UpdatedReadyReplicas is less than UpdatedReplicas, it implies UpdatedReplicas must be greater than 0 (since replica counts are non-negative). This redundancy can be removed to simplify the code and improve clarity.

            if roleStatus.ReadyReplicas < *role.Replicas ||
					roleStatus.UpdatedReadyReplicas < roleStatus.UpdatedReplicas {
				progressingRoles = append(progressingRoles, role.Name)
				isProgressing = true
			}

[gemini-code-assist]

The message for not-ready roles uses is not ready and "," as a separator. For better readability and grammatical correctness when multiple roles are listed, consider changing this to are not ready and using ", " as a separator. This also makes it consistent with the progressing message on line 142.

			fmt.Sprintf("Roles %s are not ready", strings.Join(notReadyRoles, ", ")),

[gemini-code-assist]

This logic sets the Progressing condition to False if it existed in the previous status, regardless of its previous state (True or False). To be more precise and avoid unnecessary status updates, it's better to only set the condition to False if it was previously True. This more clearly indicates a completed transition from a progressing state.

		if currentProgressingCond != nil && currentProgressingCond.Status == v1.ConditionTrue {

[googs1025]

The current Progressing logic is as here 🤔

[googs1025]

If it is Progressing, add condition.
If it is not Progressing, then if the Progressing condition exists, it means it has been completed. If not, it means it is not Progressing.

[Jeffwan]

thanks for driving the efforts. Let me take a look @googs1025

[Jeffwan]

I read the PR and notice it expose the progressing status through the condition. We may also need pause interaction. I think the initial requirement is not that clear. Let me collect more feedback and polish the original issue.

[googs1025]

I noticed that we only have Paused related fields in Storm Service controller. Do we need to have Paused field in Roleset controller as well?
