The logic is different. We perform an Additive semantics here. It means check as much as possible errors. I just don't want to immediately return in the parent function. Hence I add this block.

For the changes in the controller, I don't think the new code significantly improve the readability (the old code looks neater). What do you think?

For existing code, removing anonymous function has no impact. But usually, we don't add return call in the middle of webhook checks, which I agree with.

[cvvz]

The real problem is that we update conditions(status) too frequently, the anonymous function was introduced here to avoid too many updateStatusConditionIfNotMatch like this:

if updateErr := c.updateStatusConditionIfNotMatch(ctx, wObj, kaitov1beta1.WorkspaceConditionTypeSucceeded, metav1.ConditionFalse,
	"workspaceFailed", err.Error()); updateErr != nil {
	klog.ErrorS(updateErr, "failed to update workspace status", "workspace", klog.KObj(wObj))
	return reconcile.Result{}, updateErr
}

This will make the code messy if we use it as an error recorder.

IMO, it should be improved from two aspects:

1. use Recorder.Eventf to record important event/step rather than update condition/status during sync loop. Recorder.Eventf is one line code and we can easily track the event by kubectl describe command
2. Update crd status for only once at the end of sync loop , which includes generate and update current condition.

I filed issue https://github.com/kaito-project/kaito/issues/1067 to track.

Talk to the way to handle error. IMO, the webhook can use errs.Also to collect and return as much as possible errors. I still can't get what's the goal of the anonymous function in webhook. Could you explain to me with some specific examples? Thanks. As for the anonymous function in reconciler, it is used to avoid using too many updateStatusConditionIfNotMatch, as what I mentioned above, we should fix this from the root. I will revert my fix for this part.

[zhuangqh]

Without anonymous function, the correct logic is (following the policy to check as much as errors and don't immeidately return in parent control flow)

		var (
			cmName = i.Config
			cmNS   = namespace
			err    error
		)
		if cmName == "" {
			klog.Infof("Inference config not specified. Using default: %q", DefaultInferenceConfigTemplate)
			cmName = DefaultInferenceConfigTemplate
			cmNS, err = utils.GetReleaseNamespace()
			if err != nil {
				errs = errs.Also(apis.ErrGeneric(fmt.Sprintf("Failed to determine release namespace: %v", err), "namespace"))
			} else if err := i.validateConfigMap(ctx, cmNS, cmName, instanceType); err != nil {
				errs = errs.Also(apis.ErrGeneric(fmt.Sprintf("Failed to evaluate validateConfigMap: %v", err), "Config"))
			}
		} else if err := i.validateConfigMap(ctx, cmNS, cmName, instanceType); err != nil {
			errs = errs.Also(apis.ErrGeneric(fmt.Sprintf("Failed to evaluate validateConfigMap: %v", err), "Config"))
		}

just use anonymous function and simple return to make this logic clearer.

[zhuangqh]

I don't hold strong point about this policy. If you persist in removing this anonymous function and return immediately. I'm ok.
