WalkthroughThe watch-termination command now requires an explicitly configured positive graceful termination duration. Startup rejects invalid values, and termination-lock timeout handling uses the corrected duration variable. ChangesGraceful termination validation
Estimated code review effort: 1 (Trivial) | ~5 minutes Merge Risk: 🟡 Moderate · up to The command currently accepts 1-second and 2-second durations but may skip cleanup for them, potentially leaving the termination lock in place and suppressing the timeout event when a child does not terminate. This bounded correctness issue should be fixed or explicitly accepted before merge; the diagnostic output error is minor. 🚥 Pre-merge checks | ✅ 14 | ❌ 1❌ Failed checks (1 warning)

Handle positive durations of two seconds or less.
Lines [55]-[58] accept 1s and 2s, but Lines [175]-[178] skip the cleanup goroutine unless the duration is greater than 2s. When --termination-touch-file is set and the child does not terminate, these valid values leave the termination lock in place and suppress the GracefulTerminationTimeout event.
Either reject durations of two seconds or less, or schedule a timeout for every accepted positive duration.
Also applies to: 175-178

Handle the fmt.Println error at line 56.
cmd/watch-termination is separate from the k8s-tests-ext OTE binary, so this path does not require JSON stdout. However, fmt.Println returns an error, and this code ignores it. Check the error and return a non-zero status if the diagnostic cannot be written.

Making the
graceful-termination-durationflag required for thewatch-terminationcommand is safe because:watch-terminationbinary across all openshift repos is in KAS-O'sbindata/assets/kube-apiserver/pod.yamlwhere it is passes the flag explicitly.HyperShiftdoesn't use it.MicroShiftvendors the source but doesn't invoke it.
