             Summary: DRA resource-slice tracker goroutine leaks in tests: created with an uncancellable context and no shutdown handle
                 Key: YUNIKORN-3371
                 URL: https://issues.apache.org/jira/browse/YUNIKORN-3371
             Project: Apache YuniKorn
          Issue Type: Bug
          Components: shim - kubernetes
            Reporter: Dale Richardson


Follow-up to YUNIKORN-3357 (PR #1061); burns down the one shared leakcheck exemption
k8s.io/dynamic-resource-allocation/resourceslice/tracker.(*Tracker).initInformers.func1.

{{cache.NewContext}} and {{support.SharedDRAManager}} start the DRA resource-slice tracker's sync monitor ({{tracker.StartTracker}}) with an uncancellable context, and neither keeps a handle that a shutdown path can reach to call {{Tracker.Stop()}}. The monitor's only two exits are therefore unreachable — the context is never cancelled, and the informers it waits on are never started so they never sync. Harmless in production, where a {{Context}} is built once and lives for the process, but every test that builds a {{Context}} leaks one such goroutine permanently.

Proposed fix: create the tracker with a cancellable context, or give {{Context}} a shutdown that calls {{Tracker.Stop()}}, then delete the shared exemption.
