Describe the bug
fatal error: stack overflow
with Circular dependency detected global scope resources
To Reproduce
We had a buggy global cluster Resource LogStorage which had a ownerRef of itself.
k get LogStorage tigera-secure -oyaml | grep -A6 ownerReferences
ownerReferences:
- apiVersion: operator.tigera.io/v1
blockOwnerDeletion: true
controller: true
kind: LogStorage
name: tigera-secure
uid: 740a9840-7c61-4911-ba8a-6d1a118cfbb6
with argocd 3.3.3 and this PR?(#26640) we got a stack overflow.
Expected behavior
Circular dependency should not results in a stack overflow
