HYPERFLEET-1439 - feat: cleanup desires after deletion - #303
Conversation
…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. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>

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 :
- Event 1, delete.when is false.
ApplyResourcecreates theReadDesireand theApplyDesire(apply.go:83 and :90). - 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=NotFoundon theReadDesire. This is by design, see readdesire/status.go in the applier: "the target does not currently exist, which is not an error". - Event 2 arrives,
delete.whenis now true. Step 1 discovery reads the mirror, getsNotFound, so the executor goes into step 2 at resource_executor.go:718. - Step 2 calls cleanup.
GetDeleteDesirereturnsErrNotFound(we never posted one, DeleteResource at line 763 is never reached on this path). We fall through and delete the ReadDesire. - The
ApplyDesireis still there. The applier applies it. Now there is an object on the cluster, noReadDesireto see it, noDeleteDesireto 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.

Do not treat ErrNotSyncedYet as confirmed absence during pre-discovery.
preDiscoverAll leaves the resource absent from execCtx.Resources when discovery returns ErrNotSyncedYet. A lifecycle.delete.when expression can then evaluate against that false absence and enter executeResourceDelete. The second discovery fails before tryCleanupDesires, so desires are not removed, but the deletion still fails and retries until the read desire synchronizes. Handle only confirmed NotFound as absence in preDiscoverAll.

This still fails the whole reconciliation on ErrNotSyncedYet, we only dropped the error metric and the log level.
Something like
isNotFound := discoverErr != nil && (apierrors.IsNotFound(discoverErr) || errors.Is(discoverErr, desireclient.ErrNotSyncedYet))
What I am thinking, since not synced means we do not know, but step 2 hands it straight to CleanupAfterDeletion, which probes for an apply desire and returns ErrDeletionPending if the resource might still be on its way. It only finalizes when neither an apply nor a delete desire exists.
It would also be good to comment this in as its not 100% obvious IMO

This applies the Step 2 fix's shape to Step 6, but Step 6 needs a different outcome, not just a quieter version of the same one.
Right now, on ErrDeletionPending here we still fall through to result.Status = StatusFailed / recordResourceError / NewExecutorError, just with a Warn log and no metric instead of Error+metric. That's Health=False (adapter.executionStatus != success), same lever as Step 2.
…ost-delete cleanup Previously, ErrDeletionPending at Step 6 caused StatusFailed.

🎯 Functional Correctness | 🟠 Major | ⚡ Quick win
Test 5 locks in the slow-applier failure that was already raised at line 731 of resource_executor.go.
When Step 6 sees ErrDeletionPending, it now reports success. On the next reconciliation, the executor reaches Step 2 with a NotFound read desire and an unconfirmed delete desire. Step 2 still sets StatusFailed and calls recordResourceError, which sets Adapter.ExecutionError. The adapter then reports Health=False for a normal pending deletion. Test 5 asserts StatusFailed and require.Error, so the test enforces this behaviour.
Handle ErrDeletionPending at Step 2 the same way Step 6 does:
- Keep the resource non-nil in
execCtx.Resources, so thatFinalizedstays false. - Return success with a "deletion pending"
OperationReason. - Update Test 5 to match.
Proposed Step 2 change (`internal/executor/resource_executor.go`, lines 731-745)
if err := re.tryCleanupDesires(ctx, resource, execCtx, transportClient, transportTarget, gvk); err != nil {
if errors.Is(err, desireclient.ErrDeletionPending) {
slog.WarnContext(ctx, "resource desire cleanup: deletion pending, dependents wait",
"resource", resource.Name, "error", err)
execCtx.Resources[resource.Name] = &unstructured.Unstructured{} // or last known state; must be non-nil
result.OperationReason = "deletion pending applier confirmation"
re.metrics.ObserveDeletionDuration(resourceType, time.Since(startTime))
return result, nil
}
// existing failure handling
}The placeholder object must not satisfy dependent CEL checks by accident. If it can, persist the last known state from the read desire instead.

Verdict
COMMENT — The head commit (4e423a0, "treat ErrDeletionPending as non-fatal during post-delete cleanup") lands the step-6 fix @ciaranRoche asked for, and the DesireCleaner capability-interface design matches HYPERFLEET-1439 and the adapter delete-flow docs. This pass found only two cosmetic nits, both new. Not an approval because one prior concern (step-2 still fails the reconciliation on ErrDeletionPending) remains present and now diverges from the just-fixed step 6 — see Previous concerns. That concern is already tracked in @ciaranRoche's threads, so it is not re-posted inline.
Setup notes
None — JIRA validation ran (jira CLI available), HyperFleet standards + all 10 mechanical checks fetched cleanly, and the adapter architecture docs were consulted directly.
Summary of recommendations
| # | Severity | Category | Confidence | Location |
|---|---|---|---|---|
| 1 | nit | Pattern | High | internal/executor/resource_executor.go:299 |
| 2 | nit | Improvement | High | internal/executor/resource_executor.go:805 |
Both are inline. Mechanical checks (error-handling, resource-lifecycle, exhaustiveness, testing, code-quality, code-hygiene, naming, concurrency, security, performance), intra-PR consistency, impact analysis, and doc/code cross-referencing surfaced no other new findings. Error wrapping in cleanup.go follows the Error Model Standard (lowercase, %w, errors.Is, sentinel ErrDeletionPending), the delete switch blocks are exhaustive with defaults, and the new desiretest helpers correctly call t.Helper().
JIRA validation
Ticket HYPERFLEET-1439 — Implement the delete-confirmation lifecycle via a transport capability (Story, component Adapter).
- ✅ Capability interface, zero concrete-client assertions —
DesireCleaneris defined next to the transport contract ininterface.go; the desire client implements it (compile-timevar _ transportclient.DesireCleaner = (*Client)(nil)inclient.go); the executor consumes it only viatransportClient.(transportclient.DesireCleaner). - ✅ Same-event confirmation path (step 2) — probes the delete desire's
Successfulcondition, stores the nil/deleted sentinel, then cleans up both desires viaCleanupAfterDeletion(probes the delete/apply desires rather than re-discovering, matching the "mirror lags reality after delete" note). - ✅ Later-event orphan path (step 6) — already-cleaned and never-existed cases both close to finalized.
- ✅ Fast/slow applier timings — covered by
TestResourceExecutor_DesireTransport_FastApplier/_SlowApplier, plus a transient-NotFound regression test guarding the apply/cleanup race. ⚠️ "Selector-based discovery deletions … explicitly rejected with a documented limitation" —tryCleanupDesiresreturnsnilsilently for selector-discovered resources (resource.Discovery.ByName == "") with no log or explicit limitation marker in code; the limitation lives only in the PR description. Functionally correct (GC sweeper owns those), but the "documented limitation" aspect is thin. Already flagged by @ciaranRoche (thread); not duplicated here.
Impact warnings
None. DesireCleaner is an optional interface — the other transport implementers (k8sclient, maestroclient, dryrun recording client) opt out through the ok type assertion and keep rediscovery-based delete verification, so no files outside the PR need updating.
Previous concerns
My previous review (00ca110) tracked two items. Rechecked at 4e423a0:
-
Addressed —
ErrNotSyncedYetfailing the delete at the discovery gate (discussion_r4060340392). TheisNotFoundguard still folds in the sentinel atinternal/executor/resource_executor.go:711–internal/executor/resource_executor.go:712:apierrors.IsNotFound(discoverErr) || errors.Is(discoverErr, desireclient.ErrNotSyncedYet), so a not-yet-synced read desire flows into step 2 instead of failing at discovery. -
Addressed (step 6) — A pending deletion reported as a failed reconciliation, post-delete path (discussion_r4060320407). The head commit now makes
ErrDeletionPendingnon-fatal at step 6 (internal/executor/resource_executor.go:806–internal/executor/resource_executor.go:821): on that sentinel it restores the pre-delete discovered state (execCtx.Resources[resource.Name] = discovered), logs at Warn, and continues toStatusSuccess— exactly @ciaranRoche's suggested shape.TestResourceExecutor_DesireTransport_Step6_DeletionPending_NonFatalassertsNoError+StatusSuccess. -
Still present — A pending deletion reported as a failed reconciliation, pre-delete path (step 2) (discussion_r4036868510). Step 2 at
internal/executor/resource_executor.go:731–internal/executor/resource_executor.go:745still setsresult.Status = StatusFailed+re.recordResourceError(...)+NewExecutorError(...)onErrDeletionPending; only the log level (Warn) and the skippedDeletionStatusErrormetric differ.recordResourceErrorwritesAdapter.ExecutionError(which drivesHealth=False), so a slow-applier "resource already gone before the delete event" case still surfaces as a failed reconciliation. This contradicts the adapter delete-flow design, where a not-yet-finalized delete is an expected in-progress state (Finalized=False, reconcile again), not a hard failure — and it now diverges from the just-fixed step 6, so the identicalErrDeletionPendingfromtryCleanupDesiresis fatal at step 2 but non-fatal at step 6.TestResourceExecutor_DesireTransport_Step2_DeletionPending_DeleteNotConfirmedeven assertsStatusFailed, so the current behavior is intended in code but conflicts with the design and with step 6. Tracked in @ciaranRoche's threads; not re-posted inline.

nit — non-blocking suggestion
Category: Pattern
Confidence: High
The new discoveryTarget type was inserted between the // discoverResource discovers the applied resource… doc comment (just above) and the discoverResource function it describes. As a result godoc now attaches that comment to discoveryTarget, and discoverResource is left undocumented. Move discoveryTarget (and renderDiscoveryTarget) below discoverResource, or give the type its own comment and keep the existing comment on the function it belongs to.

Alright since Angel Bot is calling out some of my original feedback, having discussed this off PR with Michal, step 2 staying on the failure path is right. That is our lever holding Finalized back when there nothing in the resources map.
I think the main thing now holding back this PR from being merged is a comment on the step 2 block saying the executionStatus gaurd is what hold s Finalized back, as we have been back and forth on this, I dont want our future selves to 'fix' it
Adds a comment explaining why the result status and error are recorded after a post-delete action failure. - Document that Health=False reporting depends on these fields being set - Note the constraint: Finalized=True cannot be prevented without exposing a discovered resource in the execution context
