Summary

  • Add DesireCleaner optional interface to transportclient for removing transport-layer bookkeeping after confirmed resource deletion
  • Implement CleanupAfterDeletion on the desire client — removes the delete desire (only when the applier confirms deletion) then the read desire; returns an error if deletion is not yet confirmed, causing the
    executor to retry on the next reconciliation
  • Wire cleanup into the resource executor at both deletion code paths: resource already gone before delete (step 2) and post-delete re-discovery confirms removal (step 6)
  • Scoped to by-name discovery only; resources discovered by label selectors are unaffected and should be cleaned up by the garbage collector sweeper

Test plan

  • make lint
  • make test

…tion

Add DesireCleaner interface and implement CleanupAfterDeletion on the
desire client. When a resource is confirmed deleted (Step 2: already gone,
Step 6: confirmed after delete), the executor cleans up the delete desire
(only if Successful=True) and then the read desire. Scoped to by-name
discovery only.

📝 Summary

Summary by CodeRabbit

  • New Features

    • Added automatic cleanup of transport-layer deletion and read state after a resource is confirmed absent.
    • Cleanup also handles resources already missing before deletion.
    • Cleanup is skipped while deletion remains pending and reports errors when cleanup fails.
  • Bug Fixes

    • Improved lifecycle deletion handling for confirmed, pending, and partially tracked resources.
    • Added clearer error propagation for cleanup and storage failures.

Walkthrough

The change adds the optional DesireCleaner interface and implements CleanupAfterDeletion for delete and read desires. Cleanup removes confirmed bookkeeping, preserves pending deletions, and propagates lookup or deletion errors. The executor now renders discovery targets centrally and invokes cleanup when a resource is already absent or confirmed deleted. Cleanup errors fail execution. Tests cover cleanup states, error paths, target forwarding, and skipped cleanup.

Merge Risk: 🟡 Moderate · up to 8676a

Concurrent reconciliation can cause deletion cleanup to remove the bookkeeping for a newly recreated resource, leaving it unmanaged until another event restores it. Resolve the lifecycle races before merging.

Require a confirmed delete lifecycle before removing a read desire.

CleanupAfterDeletion proceeds after GetDeleteDesire returns desire.ErrNotFound, then deletes the current read desire. ResourceExecutor can concurrently reach ApplyResource, whose ensureReadDesire creates or recreates the same identity. Cleanup can therefore delete the new reconciliation’s read desire and stop discovery reconciliation for the recreated resource (CWE-367). Return without deleting the read desire when no confirmed paired delete desire exists, or correlate cleanup to that lifecycle atomically.

Make desire cleanup atomic to avoid deleting a replacement read desire. ApplyResource calls ensureReadDesire before its apply write. For a non-skip operation with a different target version, it can delete and recreate the same read-desire identity while cleanup is between removing the confirmed delete desire and calling GetReadDesire. Cleanup then reads the replacement's current version, so DeleteReadDesire succeeds instead of rejecting a stale version and removes the replacement (CWE-367). Use one atomic store operation to validate and remove the confirmed delete desire and paired read desire. Abort cleanup when reconciliation wins the race.

So coderabbit picked up on this from a concurrency angle, a reapply racing cleanup. But it also can fire sequentially too, so it is definitely a race we want to patch.

Help paint that picture ill walk through two events for the same cluster :

  1. Event 1, delete.when is false. ApplyResource creates the ReadDesire and the ApplyDesire (apply.go:83 and :90).
  2. The applier's read informer starts, does its initial List, and the object is not there yet because the apply pass has not run. It writes Reason=NotFound on the ReadDesire. This is by design, see readdesire/status.go in the applier: "the target does not currently exist, which is not an error".
  3. Event 2 arrives, delete.when is now true. Step 1 discovery reads the mirror, gets NotFound, so the executor goes into step 2 at resource_executor.go:718.
  4. Step 2 calls cleanup. GetDeleteDesire returns ErrNotFound (we never posted one, DeleteResource at line 763 is never reached on this path). We fall through and delete the ReadDesire.
  5. The ApplyDesire is still there. The applier applies it. Now there is an object on the cluster, no ReadDesire to see it, no DeleteDesire to remove it, and the adapter has already reported the resource as gone.

Returning a plain fmt.Errorf here makes the executor unable to tell "the store is broken" from "the applier has not got to it yet". Those need different handling: the first is a failure, the second is a wait.

Right now any cleanup error becomes StatusFailed, recordResourceError, a DeletionStatusError metric, and an executor error. recordResourceError writes Adapter.ExecutionError, and that goes out in the status we report to the API. So on a slow applier, a completely normal reconciliation shows up as a failed one. 🤔

I think resource.Discovery.ByName == "" will mean selector discovered resorources will skip cleanup with no log, no validation error or nothing. Reason i picked up on this is a POC i done awhile back leaked the same way.

The four executor tests prove the wiring (cleanup is called with the right namespace and name on both paths, not called when still present, failure propagates), which is good. What they cannot show is anything about desire timing, because the mock is the k8s client with a cleaner bolted on, so post-delete discovery is instantly NotFound.

  • Slow applier. Apply on event 1, mark the read desire Synced with content. Event 2 with delete.when true: assert a DeleteDesire exists, the ApplyDesire is gone, the ReadDesire is still there, result is success with the "awaiting" reason. Then mark the DeleteDesire Deleted and the ReadDesire NotFound, run event 3: assert both desires are removed and the result is success.
  • Fast applier. Same setup, but mark Deleted and NotFound between the DeleteResource call and post-delete discovery. Easiest way is a store wrapper whose CreateDeleteDesire also flips the statuses. Assert cleanup runs on event 2 and both desires are gone.
  • Transient NotFound before apply lands. Apply on event 1, mark the ReadDesire NotFound with no content, do not touch the ApplyDesire. Event 2 with delete.when true: assert the ReadDesire still exists and a DeleteDesire now exists. This is the regression test for the cleanup.go:36 comment and it fails on the current code.

The helpers in internal/desireclient/helpers_test.go (putDeleteDesire, putConfirmedDeleteDesire) are nearly what you need, they just live in the wrong package. Moving them to a small internal/desireclient/desiretest package would let both test suites share them.
