Summary

Fix for console-operator triggering excessive DeploymentUpdated events for Deployment.apps/console in the openshift-console namespace on vsphere techpreview serial clusters.

Problem

The console-operator generates excessive DeploymentUpdated events (21–31 per test run, avg 24), exceeding the pathological event threshold. This is a Component Readiness regression (pass rate dropped from 100% to ~33% on affected variants) since July 24.

Regressed test:

[Monitor:legacy-test-framework-invariants-pathological][sig-arch] events should not repeat pathologically for ns/openshift-console-operator

Affected variants: Architecture:amd64, FeatureSet:techpreview, Installer:ipi, Network:ovn, Platform:vsphere, Suite:serial, Topology:ha, Upgrade:none

Summary by CodeRabbit

  • Bug Fixes

    • Console deployments now refresh when ConfigMap content changes, using a consistent content-based hash.
    • Equivalent ConfigMap data produces stable deployment and pod-template annotations, avoiding unnecessary updates.
  • Tests

    • Updated deployment coverage to validate content-based annotation behavior.

…onfig rollout annotation

The console.openshift.io/console-config-version annotation previously
used the ConfigMap's Kubernetes ResourceVersion, which changes on every
API write even when content is identical. This caused spurious deployment
rollouts when the operator re-reconciled and re-applied the same
console-config content, doubling the DeploymentUpdated event count.

Replace GetResourceVersion() with a SHA-256 hash of the ConfigMap's Data
and BinaryData. Now only genuine content changes trigger a rollout.

Walkthrough

The console deployment now uses a deterministic SHA-256 hash of ConfigMap Data and BinaryData. Deployment and pod-template annotations no longer use the ConfigMap resource version. Tests cover content sensitivity and stable key ordering.

Changes

Console ConfigMap hash

Layer / File(s) Summary
ConfigMap hash implementation
pkg/console/subresource/deployment/deployment.go
Adds deterministic SHA-256 hashing for sorted string and binary data keys and values. The deployment annotation uses this hash.
Annotation integration and hash validation
pkg/console/subresource/deployment/deployment_test.go
Updates fixtures and annotation expectations. Adds tests for Data, BinaryData, resource-version independence, map-order independence, and content changes.

Estimated code review effort: 2 (Simple) | ~10 minutes

Merge Risk: 🟡 Moderate · up to 02f6e

The content hash can collide for certain binary ConfigMap values, potentially leaving a deployment unchanged when its configuration has changed. The PR is not merge-ready until the encoding is made unambiguous and the collision case is covered.

📄 CodeRabbit inference engine (.claude/skills/unit-test-review.md)

pkg/**/*_test.go: Most unit tests should use the table-driven test pattern, including a tests := []struct{...} table and t.Run(tt.name, ...) subtests for scenarios with multiple cases.
Test function names and subtest case names should be descriptive of the behavior or scenario being tested (for example, TestGetNodeComputeEnvironments or "Custom hostname and TLS secret set").
Use github.com/go-test/deep (deep.Equal) for struct comparisons instead of == or manual field-by-field checks.
Cover both success and failure paths in unit tests, including edge cases such as empty inputs, boundary values, missing fields, duplicates, and large inputs.
Structure tests using Arrange-Act-Assert so setup, execution, and verification are clearly separated.
When testing error-returning functions, assert error presence correctly and, when relevant, validate the error message substring instead of ignoring the error or discarding it with _.
Prefer dependency injection via interfaces for testability, and keep tests isolated so they do not depend on execution order or shared mutable state.
Extract repeated setup into helper functions when common test fixtures are reused across multiple tests.
Write specific, informative assertions that explain what failed instead of vague or silent failures.
Inline simple test data, but move complex fixtures to helper functions or testdata/ files.
Avoid tests that rely on execution order, share global mutable state, use hardcoded sleeps, omit assertions, or verify implementation details instead of behavior.

No change needed for hash encoding.

The production ConfigMap contains one Data["console-config.yaml"] entry and no BinaryData. The apply path replaces both maps with these generated values. Therefore, the cited multi-entry BinaryData collision cannot occur.

Address CodeRabbit review: replace self-referential test assertions
with independent regression test cases that use hardcoded SHA-256
digests computed outside configMapContentHash.

New TestConfigMapContentHash covers:
- Identical Data/BinaryData with different ResourceVersion → stable hash
- Map iteration order does not affect hash
- Zero-byte binary values are handled correctly
- Changed Data or BinaryData → hash changes

📄 CodeRabbit inference engine (.claude/skills/unit-test-review.md)

pkg/**/*_test.go: Most unit tests should use the table-driven test pattern, including a tests := []struct{...} table and t.Run(tt.name, ...) subtests for scenarios with multiple cases.
Test function names and subtest case names should be descriptive of the behavior or scenario being tested (for example, TestGetNodeComputeEnvironments or "Custom hostname and TLS secret set").
Use github.com/go-test/deep (deep.Equal) for struct comparisons instead of == or manual field-by-field checks.
Cover both success and failure paths in unit tests, including edge cases such as empty inputs, boundary values, missing fields, duplicates, and large inputs.
Structure tests using Arrange-Act-Assert so setup, execution, and verification are clearly separated.
When testing error-returning functions, assert error presence correctly and, when relevant, validate the error message substring instead of ignoring the error or discarding it with _.
Prefer dependency injection via interfaces for testability, and keep tests isolated so they do not depend on execution order or shared mutable state.
Extract repeated setup into helper functions when common test fixtures are reused across multiple tests.
Write specific, informative assertions that explain what failed instead of vague or silent failures.
Inline simple test data, but move complex fixtures to helper functions or testdata/ files.
Avoid tests that rely on execution order, share global mutable state, use hardcoded sleeps, omit assertions, or verify implementation details instead of behavior.

Encode field boundaries and test binary values that contain 0x00.

Line 2277 creates an empty binary value. It does not test a binary value that contains a zero byte.

The current helper writes key, 0x00, value, and 0x00 without length prefixes. BinaryData{"a": []byte("x\x00b\x00y")} and BinaryData{"a": []byte("x"), "b": []byte("y")} produce the same hash input, although they produce different ConfigMap files. A content change can then retain the deployment annotation and suppress the required rollout.

Encode each section, key, and value with unambiguous type and length boundaries. Add a regression case that asserts these two ConfigMaps have different hashes.

Also applies to: 2339-2359

2279, Update the ConfigMap hash helper used by the deployment annotation logic
to encode each section, key, and value with explicit type and length boundaries,
preventing embedded zero bytes or multiple entries from producing identical hash
inputs. Extend the relevant regression tests around the existing zero-byte
binary case to compare BinaryData{"a": []byte("x\x00b\x00y")} with
BinaryData{"a": []byte("x"), "b": []byte("y")} and assert their hashes differ.
