Merge pull request #16986 from enj/enj/i/rbac_memory/16954
Automatic merge from submit-queue. UPSTREAM: 54257: Use GetByKey() in typeLister_NonNamespacedGet The Get() function of non-namespace lister passes a temporary object to indexer.Get() in order to fetch the actual object from the indexer. This may cause Go to allocate the temporary object on the heap instead of the stack, as it is passed into interfaces. For non-namespaced objects, Get(&Type{ObjectMeta: v1.ObjectMeta{Name: name}}) should be equivalent to GetByKey(name). This could be the root cause of excessive allocations, e.g. in tests clusterRoleLister.Get() has trigger 4 billion allocations. Signed-off-by: Christian Heimes <cheimes@redhat.com> Signed-off-by: Monis Khan <mkhan@redhat.com> Fixes #16954 /assign @deads2k @simo5
