OCPBUGS-104854: Fix excessive DeploymentUpdated events via content hash#1210redhat-chai-bot wants to merge 1 commit into
Conversation
…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. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>

pkg/**/*_test.go: Most unit tests should use the table-driven test pattern, including atests := []struct{...}table andt.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,TestGetNodeComputeEnvironmentsor"Custom hostname and TLS secret set").
Usegithub.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 ortestdata/files.
Avoid tests that rely on execution order, share global mutable state, use hardcoded sleeps, omit assertions, or verify implementation details instead of behavior.

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win
Add independent regression cases for the rollout invariant.
The expected values call configMapContentHash, which is also used by production code. These assertions can pass even when the helper's serialization is incorrect. They do not independently verify that a ResourceVersion-only rewrite keeps the annotation stable or that a Data or BinaryData change updates it.
Add table-driven cases that compare generated annotations for identical content with different ResourceVersion values and for changed content. Include map-order variation and binary values containing zero bytes. Use an independent expected digest or compare the generated annotations directly.
As per path instructions, pkg/**/*_test.go tests should use table-driven cases and cover edge cases.

Fix for console-operator triggering excessive DeploymentUpdated events for
Deployment.apps/consolein theopenshift-consolenamespace on vsphere techpreview serial clusters.Problem
The console-operator generates excessive
DeploymentUpdatedevents (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:
Affected variants: Architecture:amd64, FeatureSet:techpreview, Installer:ipi, Network:ovn, Platform:vsphere, Suite:serial, Topology:ha, Upgrade:none
