Summary

Part of #776, defect 1 (and the operator side of defect 3).

A config change records its keys for the whole NodeWright. With keys present, NodeState.HasInterrupt only consulted the configInterrupts entries matching them, so a package whose own interrupt never ran on a node (for example a reboot that was failing) completed at config without it and the node was uncordoned. A node that newly matched the selector, or was reset after a config cycle, hit the same thing through the stale keys.

Change

Option A from the issue, tracked per node and package.

• PackageStatus.InterruptPending (interruptPending): set at apply or upgrade for a package that declares its own interrupt, cleared once the interrupt completes (interrupt/complete, including a skipped interrupt promoted to complete) or the package reaches post-interrupt, carried by Upsert otherwise. Clearing at interrupt/complete matters: a config reset of a node at that state must not run the package's own interrupt, such as a reboot, a second time. The wrapper's Upsert supplies whether the package declares one, so packages without an interrupt never get the flag and their node annotations are unchanged.
• HasInterrupt: with config keys recorded, true when a configInterrupts entry matches or the package's own interrupt is still owed on this node. With no keys it is unchanged.
• fudgeInterruptWithPriority takes a per-node owesOwn and adds the package's own interrupt to the matching ones, so the existing priority picks the winner (a reboot beats a service restart).
• package rerun --stage and update-state set the flag on apply/upgrade only for a package that declares an interrupt, and clear it on post-interrupt (and on interrupt/complete for update-state).
• The per-node choice goes through a small nodeInterrupt helper so a spec can cover the node.OwesOwnInterrupt wiring.
• CRD field in config/crd and chart/templates (both groups), legacy conversion, docs.

No migration shim. The issue asked for one so existing entries read as complete. The flag is stored inverted (pending, not complete), so an entry written before the field existed already reads as "not owed" and nothing re-runs on upgrade. The only gap is a node mid-rollout at upgrade time with keys already recorded, which keeps today's behavior.

Not in this PR

• Defect 2 (the gate resetting nodes mid-apply) is already handled on main by the resettable set from fix(operator): only reset complete or erroring nodes on config update #788.
• fix(operator): do not record a config Job that ran on replaced ConfigMap data #810 (in-flight completion) and the envtest follow-up from fix(operator): only reset complete or erroring nodes on config update #788 are separate.

Test plan

• NodeState: flag set, carried and cleared across stages (including interrupt/complete and a promoted skipped interrupt); owed vs settled; matched configInterrupts still run after the own one ran; unchanged with no keys
• wrapper Upsert flags only a package with its own interrupt
• fudgeInterruptWithPriority adds the own interrupt only where owed; a spec on a real wrapped node through nodeInterrupt fails if node.OwesOwnInterrupt is replaced with nil
• package rerun and update-state flag handling, including packages without an interrupt
• conversion fixture covers the new field
• mock regenerated with make generate-mocks (only SkyhookNode.go changed)
• From operator/: make lint; go test ./api/... ./cmd/... ./internal/wrapper/... ./internal/controller/... (envtest 1.34.1). CI ran the chainsaw e2e suites on the earlier commits and passed.

This replaces #878 (same branch, now pushed to NVIDIA/nodewright so CI runs without fork approval). The review there is addressed and the replies are on #878:

• ayuskauskas: flag now cleared at (interrupt, complete), in ProgressSkipped and in update-state; mock regenerated with make generate-mocks.
• lockwobr: nodeInterrupt helper plus a real-node spec for node.OwesOwnInterrupt, and rerun/update-state flag specs; user-guide sentence qualified.
• CodeRabbit: rerun and update-state set the flag only for packages with an interrupt, and rerun --stage post-interrupt clears it.

The threads there are left open for the reviewers to resolve.

📝 Walkthrough

The change adds an optional interruptPending status field to package entries and tracks whether a package still owes its own interrupt. Controller interrupt selection now considers that state alongside matching config interrupts. CLI rerun and update-state operations set or clear the flag based on the requested stage and state. CRD schemas, tests, and documentation are updated to describe and validate the behavior.

Change: Bug fix

Possibly related issues

• [BUG]: Config updates can skip a package's own interrupt, reset nodes mid-apply, and leave stale keys #776 — The issue describes config updates skipping a package’s own interrupt, which this change addresses with per-node pending state and controller interrupt selection.

• NVIDIA/nodewright#878 — This PR addresses the same package-owned interrupt behavior and changes the pending-state, controller-selection, CLI, and schema paths.

Merge Risk: 🔵 Low · up to 77b30

Clarify the config-change guidance so operators do not mistake a completed package interrupt for a reason that matching config interrupts cannot run. This is a bounded documentation issue and does not block merging.

Limit the retry claim to the package’s own interrupt.

A matching configInterrupts entry can trigger an interrupt after interruptPending is cleared. The first sentence says an interrupt runs only while the node still owes the package’s own interrupt. Change it to “A configMap change retries the package’s own interrupt only on a node that still owes it.” As per coding guidelines, “keep docs/ in sync with any behavior change in the same PR.”
