Kubernetes: Quiet Data Gets a Second Look

Today's activity centers on a wave of fixes for update-path validation bugs, where checks that only inspect a new object's data—ignoring what's already safely stored—reject valid, unchanged resources. Five duplicate PRs also landed to fix ControllerRevision restores in StatefulSets, alongside continued arithmetic overflow cleanup in autoscaling.

Contributor thc1006 shows up three times with this exact theme. PR 142170 fixes LimitRanger so it stops re-checking persistent volume claim min and max limits on every…

A related thread is precision and overflow bugs. PR 142192 fixes an HPA utilization calculation that silently overflowed at very large pod metric values, sometimes reporting zero percent utilization instead of the real number. PR 142215 fixes a similar zero-guard problem in kubectl describe node, which was printing…

On the reliability side, five nearly identical PRs — 142159 through 142163 — all restore only the spec field from a ControllerRevision when rolling back a StatefulSet, preventing unintended changes to other parts of the object. The duplication looks like parallel backports rather than redundant work, but it's worth…

Elsewhere, pohly's DRA capacity-naming fix in 142202 addresses a driver-prefix mismatch that was silently breaking resource claims, and thc1006's 141118 tightens…
