Walkthrough

The BSL configuration builder now propagates CloudStorage region settings only for AWS providers. Non-AWS reconciliation removes stale region settings. Azure and GCP tests no longer expect automatic region values.

Changes

CloudStorage region propagation

Layer / File(s)	Summary
Provider-specific region handling internal/controller/bsl.go	The controller assigns CloudStorage regions only for AWS providers and removes stale region values during non-AWS reconciliation.
Non-AWS reconciliation expectations internal/controller/bsl_test.go, internal/controller/cloudstorage_providers_integration_test.go	Azure and GCP tests no longer expect generated region settings. GCP tests continue to validate project and snapshot location settings where applicable.

Out of Scope Changes check	✅ Passed	Check skipped because no linked issues were found for this pull request.
Stable And Deterministic Test Names	✅ Passed	The PR only removes expected region entries from Go test fixtures. No Ginkgo title changes were added; existing tests use static table names via t.Run(tt.name).
Test Structure And Quality	✅ Passed	The touched tests are standard testing.T tests using fake clients, not Ginkgo; the PR only updates expected config maps and adds no cluster resources, waits, or new assertion-quality issues.
Microshift Test Compatibility	✅ Passed	The PR adds no Ginkgo e2e tests; it only updates existing ordinary Go tests and removes expected region values, so the MicroShift check is not applicable.
Single Node Openshift (Sno) Test Compatibility	✅ Passed	The PR changes controller logic and existing standard Go test expectations only; it adds no Ginkgo e2e tests or multi-node/HA assumptions.
Topology-Aware Scheduling Compatibility	✅ Passed	The PR changes only BSL region configuration and test expectations. The diff adds no replicas, affinity, topology spread, node selectors, tolerations, or PDB scheduling constraints.
Ote Binary Stdout Contract	✅ Passed	The three-file diff only changes BSL region handling and test fixtures; it adds no stdout or logging call in main, init, TestMain, or suite setup.
Ipv6 And Disconnected Network Test Compatibility	✅ Passed	The PR adds no new Ginkgo e2e tests. It only removes expected region entries from existing Go table tests, with no IPv4 or external-connectivity assumptions introduced.
No-Weak-Crypto	✅ Passed	The full PR diff contains only provider-region mapping changes and test updates; no MD5, SHA1, DES, RC4, Blowfish, ECB, custom crypto, or secret comparison changes were added.

No-Sensitive-Data-In-Logs	✅ Passed	The complete PR diff adds no logging calls or log fields. It only changes region propagation and test expectations; sensitive literals and existing logs are unchanged.

- Around line 261-266: Update the BSL reconciliation flow around the region
handling and configuration merges to remove any existing
bsl.Spec.Config["region"] for non-AWS providers, including when
bucket.Spec.Config is nil or during provider transitions. Perform the cleanup
after all configuration merges, while preserving region assignment only for
supported AWS configurations.
- Around line 261-266: Update the region propagation condition in the BSL
configuration handling to allow bucket.Spec.Region only when
bucket.Spec.Provider is AWSBucketProvider. Remove the current non-GCP exclusion
so Azure and other providers do not receive config.region, while preserving the
existing non-empty region and config initialization behavior.

Defensive cleanup: consider removing any stale region key for non-AWS providers after the config merge block. If bucket.Spec.Config is nil and the BSL previously carried a region from an earlier AWS reconciliation, that stale key will persist.

if bucket.Spec.Provider != oadpv1alpha1.AWSBucketProvider {
    delete(bsl.Spec.Config, "region")
}
