fix(cloud-functions): delete deployment before function

[sanjay-saxena]

TL;DR

Delete an existing function deployment before deleting the function record. This preserves deployment cleanup and records deployment deletion in the audit trail.

Additional Details

Function deletion now checks for a deployment and deletes it first. The deployment cleanup removes the queue and workers, records the deployment audit event, and then allows function and secret cleanup to proceed. Function versions that were never deployed continue to delete successfully.

For the Reviewer

Review the deletion sequence in FunctionManagementService and the optional deployment cleanup path in FunctionDeploymentService.

For QA

• Added a controller regression test for deleting an undeployed function.
• Not run locally. The nvcf-core:tests target requires Docker.
• QA Needed: No

Issues

Fixes #1251

Checklist

• I am familiar with the Contributing Guidelines.
• I have signed off my commits for Developer Certificate of Origin (DCO) compliance.
• New or existing tests cover these changes.
• The documentation is up to date with these changes.

Summary by CodeRabbit

• Bug Fixes
  • Improved function deletion handling for versions without deployments.
  • Function deletion now completes successfully and returns 204 No Content when no deployment exists.
  • Deployment deletion is recorded in the operation audit trail.
  • Added clearer deletion activity logging.

📝 Walkthrough

Walkthrough

Function version deletion now conditionally removes an existing deployment, includes deployment deletion in audit processing, logs deletion lifecycle events, and supports deletion of undeployed versions without throwing.

Changes

Function deletion

Layer / File(s)	Summary
Conditional deployment cleanup src/control-plane-services/cloud-functions/nvcf-core/src/main/java/com/nvidia/nvcf/service/function/FunctionDeploymentService.java	The service delegates deletion through an entity/deployment overload and adds deleteFunctionDeploymentIfPresent. forceDeleteFunctionDeployment is now private.
Function deletion orchestration and validation src/control-plane-services/cloud-functions/nvcf-core/src/main/java/com/nvidia/nvcf/service/function/FunctionManagementService.java, src/control-plane-services/cloud-functions/nvcf-core/src/test/java/com/nvidia/nvcf/rest/function/management/FunctionManagementControllerTest.java	Function deletion logs lifecycle events, invokes conditional deployment cleanup with audit payload support, and retains related audit operations. The test verifies successful deletion of an undeployed function version.

Estimated code review effort: 3 (Moderate) | ~20 minutes

Merge Risk: 🟠 High · up to ef971

Function deletion can remove the function record and secrets even when deployment cleanup fails, leaving orphaned resources and an incorrect successful outcome. The PR is not merge-ready until cleanup failures stop the remaining deletion.

Explanation

The implementation addresses deployment-first deletion, cleanup delegation, audit payload support, and undeployed function deletion. The summary confirms a regression test for undeployed deletion, but it does not confirm test coverage for deployed deletion.

Update deletion-flow documentation if it exists.

This change makes deployment cleanup and deployment auditing occur before function and secret deletion. Confirm whether an architecture or sequence diagram documents this flow. Update it if needed.

As per coding guidelines: When a change modifies runtime behavior, data flow, or component interactions, ask whether architecture or sequence diagrams need updating.

Add a deployed deletion test to FunctionManagementControllerTest.

FunctionManagementService.deleteFunction calls deleteFunctionDeploymentIfPresent, but the existing tests create no deployment. They do not cover deployment, queue, worker, or deployment-audit cleanup.
