This fixes REST unembargo deadlocks by locking related affects and trackers before flaw updates that can cascade into visibility/tracker saves.
I also added regression coverage for both deadlock shapes we found:

  • concurrent unembargo of flaws sharing a tracker
  • concurrent affect save while a flaw is being unembargoed

Closes OSIDB-5456.

Review Change Stack

📝 Summary

Summary by CodeRabbit

  • Bug Fixes
    • Improved reliability when unembargoing flaws that share trackers or have concurrent affect updates.
    • Prevented deadlocks during simultaneous flaw, affect, and tracker changes.
    • Added safer retry handling for temporary update conflicts.
    • Improved consistency when flaw updates trigger related tracker changes, including major-incident status transitions.
    • Preserved successful unembargo behavior during concurrent updates.
    • Ensured related records remain synchronized after concurrent unembargo operations.

Walkthrough

FlawSerializer.update now detects tracker-affecting changes, locks related affects and trackers in deterministic UUID order during active transactions, and refreshes the flaw. Threaded tests cover concurrent unembargo operations and affect updates.

Changes

Flaw unembargo concurrency

Layer / File(s) Summary
Transactional locking and change detection
osidb/serializer.py
The serializer uses explicit change flags for component, general-field, major-incident, and impact updates. Inside atomic transactions, it locks related affects and trackers in UUID order before refreshing the flaw.
Concurrent unembargo validation
osidb/tests/endpoints/flaws/test_unembargo.py, .secrets.baseline
Threaded tests cover shared-tracker unembargo and affect-update retry behavior during row-lock contention. The secrets baseline updates the recorded source line.

2530-2540: 🩺 Stability & Availability

No FOR UPDATE incompatibility exists here.

AffectManager adds only a scalar Subquery annotation and prefetch_related("tracker"). The subsequent values_list("uuid", flat=True) selects only uuid and returns scalar values, so these additions do not add the claimed query cost. The locking query has no aggregate, GROUP BY, DISTINCT, or outer join.

No change needed. ATOMIC_REQUESTS is enabled for the default database in deployed, local, and CI settings, so HTTP flaw updates run inside an atomic block.

No change is required for this concern.

TrackingMixinManager does not apply ACL filtering, and AffectManager adds only a scalar Subquery and prefetch_related("tracker"). This path does not add an aggregate, DISTINCT, or GROUP BY.

serializer to compare incoming values with the stored flaw, rather than
triggering solely when tracker-relevant keys appear in validated_data. Reuse the
comparison behavior from update_trackers so title-only or unchanged full PUT
requests do not acquire related affects and tracker locks, while genuine changes
to components, cve_id, impact, major_incident_state, or unembargo_dt still
trigger updates.

Do not report this deadlock. Tracker.can_unembargo() returns False while any tracker-linked affect remains embargoed, so Tracker.unembargo() does not traverse to the other flaw’s affect in the stated scenario.

2540-2549: Restore value-based lock detection.

The intersection checks field presence, not a changed value. Any request that resubmits these unchanged fields takes locks on all related Affect and Tracker rows. This blocks concurrent related updates during the transaction. Compare the incoming values with flaw, and use _major_incident_update_affects_trackers for major_incident_state before locking.

The REST flaw update path is atomic.

FlawView and FlawV1View use FlawSerializer or its subclass. The active environment-specific settings inherit the base settings and enable ATOMIC_REQUESTS=True. The inspected flaw views have no non-atomic override. The proposed REST race path is not supported.

Make the concurrent affect update observable.

AffectFactory can initialize impact to Impact.LOW, making the concurrent update a no-op. The unembargo recursion also performs a full Affect.save(), so the current embargo assertions do not prove that the retry leaves Impact.LOW persisted.

Set a non-LOW initial impact and assert the final impact.

Proposed change
         flaw = FlawFactory(
             embargoed=True,
+            impact=Impact.MODERATE,
             unembargo_dt=datetime(2030, 10, 10, tzinfo=timezone.utc),
         )
         affect = AffectFactory(
             flaw=flaw,
+            impact=Impact.MODERATE,
             affectedness=Affect.AffectAffectedness.AFFECTED,
...
         assert not Affect.objects.get(uuid=affect.uuid).is_embargoed
+        assert Affect.objects.get(uuid=affect.uuid).impact == Impact.LOW

2540-2549: 🚀 Performance & Scalability | 🟠 Major

Compare values before locking related rows.

This reintroduces the presence-based condition from the earlier review. A full PUT can include unchanged tracker-relevant fields. The request then locks every related Affect and Tracker, although update_trackers later performs no tracker save. Compare each supplied value with flaw before acquiring the locks.

Proposed fix

-            validated_data.keys()
-            & {

2569-2570: 🩺 Stability & Availability

The flaw update route runs inside an active transaction. All deployed settings enable ATOMIC_REQUESTS, and FlawView uses FlawSerializer. Therefore _lock_related_update_rows() takes the related-row locks before unembargo() opens its nested transaction. The proposed outer transaction is not needed for the API route.

Make the concurrent affect update observable.

AffectFactory assigns a random impact from the values not greater than the flaw impact, so the initial impact can already be Impact.LOW. The concurrent update then writes the same value and the retry path is not verified. The final assertions at lines 531-532 only check embargo state.

Set a non-LOW initial impact and assert the persisted impact after both threads finish.

💚 Proposed change
         flaw = FlawFactory(
             embargoed=True,
+            impact=Impact.MODERATE,
             unembargo_dt=datetime(2030, 10, 10, tzinfo=timezone.utc),
         )
         affect = AffectFactory(
             flaw=flaw,
+            impact=Impact.MODERATE,
             affectedness=Affect.AffectAffectedness.AFFECTED,
             resolution=Affect.AffectResolution.DELEGATED,
             ps_update_stream=ps_update_stream.name,
             ps_component="component",
         )

And after the joins:

         assert not Affect.objects.get(uuid=affect.uuid).is_embargoed
+        assert Affect.objects.get(uuid=affect.uuid).impact == Impact.LOW
