Summary

  • Add checkAPIServer and statusFlush concurrency guards to RunDeprovisioningLifecycle, matching the protection already present in RunProvisioningLifecycle
  • Without these guards, rapid reconciles with a stale informer cache could trigger duplicate AAP deprovision jobs
  • Fix pre-existing bug in storage_controller.go where checkAPIServer closures used r.Client (stale informer cache) instead of r.APIReader (direct API server read)
  • Add CheckAPIServer != nil validation to validateDeprovisionTargets for consistency with validateJobTargets

Changes

Core (pkg/provisioning/provision_lifecycle.go)

  • New CheckAPIServer field on DeprovisionTarget struct
  • RunDeprovisioningLifecycle and RunMultiTargetDeprovisioningLifecycle now accept checkAPIServer and statusFlush callbacks
  • statusFlush guarded with !result.IsZero() — only called when a deprovision job was actually triggered (avoids 409 Conflict on skip/unmanaged paths)
  • New helpers: CheckAPIServerForNonTerminalDeprovisionJob, CheckAPIServerForNonTerminalDeprovisionJobAndTarget

Controllers (10 osac-operator controllers)

  • All controllers updated with proper checkAPIServer (using r.APIReader) and statusFlush closures for deprovisioning
  • storage_controller.go: additionally fixed 6 closures that incorrectly used r.Client instead of r.APIReader

Tests

  • 2 new ClusterOrder integration tests: stale cache guard verification and race condition scenario (verifies exactly 1 deprovision job after rapid reconciles)
  • 1 new unit test: validateDeprovisionTargets rejects nil CheckAPIServer
  • All existing DeprovisionTarget test structs updated with required CheckAPIServer field

Known Gaps (follow-up PRs)

  • bare-metal-fulfillment-operator: passes nil, nil for checkAPIServer/statusFlush — these controllers lack APIReader fields. Proper implementation requires adding APIReader to their reconcilers.
  • RunMultiTargetDeprovisioningLifecycle triggered heuristic: currently uses allTargetsTriggered (all-or-nothing). A per-target Triggered flag would be more precise when only some targets trigger jobs in a given reconcile.

Test plan

  • go build ./... passes
  • make lint — 0 issues
  • make test — all 670 tests pass (668 existing + 2 new integration tests)
  • bare-metal-fulfillment-operator builds and lints clean
  • E2E validation of deprovisioning with concurrent reconciles

Summary by CodeRabbit

  • Bug Fixes

    • Improved deprovisioning reliability by checking the API server for active jobs, even when local cache data is stale.
    • Prevented duplicate deprovisioning jobs during rapid reconciliation cycles.
    • Improved persistence of provisioning and deprovisioning status updates, including conflict retries.
    • Enhanced multi-target deprovisioning to track jobs and flush status consistently.
  • Tests

    • Added coverage for stale cache scenarios, duplicate-job prevention, status updates, and multi-target lifecycle behavior.

RunDeprovisioningLifecycle lacked the checkAPIServer and statusFlush
concurrency guards that RunProvisioningLifecycle already has. Without
these guards, rapid reconciles with a stale informer cache could
trigger duplicate AAP deprovision jobs.

Changes:
- Add CheckAPIServer field to DeprovisionTarget and wire it into
  RunDeprovisioningLifecycle/RunMultiTargetDeprovisioningLifecycle
- Add statusFlush callback to persist status after job trigger,
  preventing stale-object 409 conflicts on subsequent updates
- Guard statusFlush with !result.IsZero() so it only runs when a
  deprovision job was actually triggered (not on skip/unmanaged)
- Add CheckAPIServer nil validation to validateDeprovisionTargets
- Update all 10 osac-operator controllers with proper checkAPIServer
  (using r.APIReader) and statusFlush closures
- Fix pre-existing bug in storage_controller.go: checkAPIServer
  closures used r.Client (stale cache) instead of r.APIReader
- Pass nil for checkAPIServer/statusFlush in bare-metal-fulfillment-
  operator controllers (proper implementation is a follow-up)

Add integration and unit tests for the new checkAPIServer and
statusFlush guards in RunDeprovisioningLifecycle:

- Integration test: verify CheckAPIServerForNonTerminalDeprovisionJob
  detects an existing job even when the in-memory object is stale
- Integration test: simulate rapid reconciles with stale cache and
  verify exactly one deprovision job exists (race condition guard)
- Unit test: verify validateDeprovisionTargets rejects nil
  CheckAPIServer
- Update all DeprovisionTarget test structs with CheckAPIServer field
  to satisfy the new validation requirement

Review Change Stack

Walkthrough

Deprovisioning lifecycle APIs now detect active jobs through the API server and persist status after triggers. OSAC controllers provide these callbacks, storage reads use APIReader, and tests cover stale caches, duplicate prevention, validation, and multi-target behavior.

Changes

Deprovisioning lifecycle

Layer / File(s) Summary
Lifecycle callbacks and multi-target handling
osac-operator/pkg/provisioning/provision_lifecycle.go
The lifecycle checks for active deprovision jobs, supports status flushing, tracks multi-target triggers, and validates required callbacks.
Controller integration and API-server reads
osac-operator/internal/controller/*_controller.go, bare-metal-fulfillment-operator/internal/controller/*_controller.go
OSAC controllers pass API-server job checks and retrying status updates. Storage provisioning reads non-terminal jobs through APIReader. Bare-metal callers pass nil callbacks.
Lifecycle test coverage
osac-operator/pkg/provisioning/provision_lifecycle_test.go, osac-operator/internal/controller/clusterorder_integration_test.go
Tests cover the expanded callback contracts, stale informer caches, duplicate prevention, validation, trigger errors, and multi-target completion.

Estimated code review effort: 4 (Complex) | ~45 minutes

Merge Risk: 🟠 High · up to 78e6d

Deprovisioning can still launch duplicate external jobs when API reads fail, status updates conflict, or bare-metal controllers reconcile against stale state without the new guards. This is a high-impact correctness risk that should be fixed before merging.

672-694: 🚀 Performance & Scalability | 🔵 Trivial | ⚡ Quick win

Flush only after a new job is created.

Line 677 sets triggered for an already persisted non-terminal job after a polling pass. Line 690 then calls statusFlush on every reconciliation while that job remains active. Record the target job ID before the lifecycle call and flush only when that call creates or replaces the deprovision job.

Add duplicate-job guards to bare-metal deprovisioning.

Both calls disable checkAPIServer and statusFlush. A rapid reconciliation with stale job status can therefore trigger the same external deprovision job more than once.

  • bare-metal-fulfillment-operator/internal/controller/baremetalinstance_controller.go#L790-L794: pass a direct API-server non-terminal job check and a retrying status-flush callback.

Read the latest object through the API reader in every status-retry helper.

A cached r.Get can reuse a stale resourceVersion across conflict retries. The flush can then fail, while the lifecycle only logs the error. The job status remains unpersisted, so a later reconcile can trigger a duplicate external job.

Use r.mgr.GetLocalManager().GetAPIReader() for ComputeInstanceReconciler and r.APIReader for the other four reconcilers.

Do not treat an API read error as no active job.

Line 498 returns false for every apiReader.Get error. The lifecycle then triggers a deprovision job although it could not verify that another reconciliation has not already persisted one. Propagate the error through the callback contract, or requeue without triggering when the direct read fails.

As per path instructions, "Never ignore error returns."

converted into “no active job”: propagate the error through its callback
contract, or requeue and return without triggering deprovision when the direct
read fails. Preserve the existing false result only for a successful read that
confirms no active job, and update callers of this callback as needed.

Looks good to me — this PR correctly extends the deprovisioning lifecycle with the same concurrency guards (checkAPIServer + statusFlush) already present in the provisioning path, and fixes the pre-existing r.Client vs r.APIReader bug in storage_controller.go. A few low-severity observations below.

Review

Findings

Low

  • [logic-error] osac-operator/pkg/provisioning/provision_lifecycle.go:679 — In RunMultiTargetDeprovisioningLifecycle, the triggered flag is set to true whenever any target has a non-terminal deprovision job after runDeprovisioningLifecycleForTarget returns — not only when a new job was created during this call. This causes statusFlush to fire during polling cycles (pre-existing job still running), producing unnecessary API server writes. The provisioning counterpart (RunMultiTargetProvisioningLifecycle) avoids this by using runLifecycleCore's explicit triggered return value, which only reports true when a genuinely new job was created. No production controller currently calls RunMultiTargetDeprovisioningLifecycle, so impact is theoretical.
    Remediation: Compare the deprovision job ID before and after the per-target call to detect genuinely new triggers.

  • [race-condition-pre-existing] osac-operator/pkg/provisioning/provision_lifecycle.go:603 — The checkAPIServer and statusFlush guards cover the initial trigger path (!HasJobID) but not the backoff retrigger path in handleDeprovisionBackoffForTarget, which calls triggerDeprovisionJobForTarget directly. The provisioning side gates all trigger paths through evaluateAction. Not introduced by this PR; noted for follow-up parity.

  • [doc-comment-inconsistency] osac-operator/pkg/provisioning/provision_lifecycle.go:486CheckAPIServerForNonTerminalDeprovisionJob omits the extract parameter description that its provisioning counterpart includes ("The extract parameter (a JobsExtractor) determines which jobs array to check").
    Remediation: Add the extract parameter description to match the provisioning counterpart's doc template.

  • [doc-comment-inconsistency] osac-operator/pkg/provisioning/provision_lifecycle.go:493CheckAPIServerForNonTerminalDeprovisionJobAndTarget has a single-line doc while its provisioning counterpart explains why the targeted variant is needed.
    Remediation: Expand to match the provisioning counterpart's level of detail.

  • osac-operator/pkg/provisioning/provision_lifecycle.go:679: [low] logic-error

In RunMultiTargetDeprovisioningLifecycle, the triggered flag is set to true whenever any target has a non-terminal deprovision job after runDeprovisioningLifecycleForTarget returns, not only when a new job was created during this call. This causes statusFlush to fire during polling cycles, producing unnecessary API server writes. The provisioning counterpart avoids this via runLifecycleCore's explicit triggered return value. No production caller exists today.

Suggested fix: Compare the deprovision job ID before and after the per-target call to detect genuinely new triggers, matching the provisioning side's approach.

  • osac-operator/pkg/provisioning/provision_lifecycle.go (file-level): Line 603 · [low] race-condition-pre-existing

The checkAPIServer and statusFlush guards cover the initial trigger path (!HasJobID) but not the backoff retrigger path in handleDeprovisionBackoffForTarget, which calls triggerDeprovisionJobForTarget directly. The provisioning side gates all trigger paths through evaluateAction. Not introduced by this PR; noted for follow-up parity.

  • osac-operator/pkg/provisioning/provision_lifecycle.go:486: [low] doc-comment-inconsistency

CheckAPIServerForNonTerminalDeprovisionJob omits the extract parameter description that its provisioning counterpart includes.

Suggested fix: Add the extract parameter description to match the provisioning counterpart's doc template.

  • osac-operator/pkg/provisioning/provision_lifecycle.go:493: [low] doc-comment-inconsistency

CheckAPIServerForNonTerminalDeprovisionJobAndTarget has a single-line doc while its provisioning counterpart explains why the targeted variant is needed.

Suggested fix: Expand to match the provisioning counterpart's level of detail.
