I see... let's wait for openshift/library-go#2171 to merge first before moving forwards with this PR |

top level PR we're waiting on is openshift/api#2813 |
Temporarily use library-go PR #2171 (jubittajohn/library-go@af1b16e) which includes the HasSyncedChecker() method required by K8s 1.36. This unblocks the K8s 1.36 upgrade. Once library-go#2171 merges, this replace directive should be removed. Co-Authored-By: Claude Sonnet 4.5 <noreply@anthropic.com>

@dlom Updated and ready! ✅ Rebased on latest master The PR now uses a replace directive to pull from the library-go PR branch. Once #2171 officially merges, I'll update to remove the replace directive and use the upstream version. |

Do not claim startup failures are checked.
TestK8s136ControllerManagerStarts only reads the Deployment’s Available condition; it does not inspect startup failures. Change this to state that the test verifies Available=True, or extend the test accordingly.

Avoid publishing full operator logs.
This writes raw pod logs into CI artifacts, which may expose internal hostnames, customer data, or credentials. Log the matched pattern and a bounded, redacted excerpt instead. As per coding guidelines, flag logging that may expose sensitive or internal data.

Reviewed the current head (aa194f6d). The Kubernetes/OpenShift dependency update itself looks unblocked now that the upstream PR chain has merged. I found a few correctness and safety issues in the new e2e coverage that should be addressed before merge:
- Apply
testTimeoutto the contexts used for Kubernetes API and pod-log calls. It is currently declared but unused. - Fail the log assessment when every
GetLogscall fails; otherwise it can pass without inspecting any pod logs. - Avoid printing raw pod logs when an error pattern matches. The logs may contain sensitive cluster data; reporting the pod and matched pattern is sufficient.
- Require the Deployment to contain an explicit
Available=Truecondition. The current loop succeeds when the condition is absent. - Restore
os.Exit(testenv.Run(m))inTestMainand remove the documentation claim that the controller-manager test detects startup failures, since it currently checks only Deployment availability.
I applied these changes locally and validated them with:
git diff --check
go test -tags e2e -run '^$' ./test/e2e/k8s136/...
Both checks pass. I have the patch ready and can share it or coordinate the changes with you.
Separately, the current ci/prow/security failure appears unrelated to this PR's source changes: Snyk is flagging Go standard-library vulnerabilities in the CI image's Go 1.26.4, fixed in Go 1.26.5.
Address feedback from code review: 1. Apply testTimeout to all Kubernetes API and pod-log contexts 2. Fail log assessment when all GetLogs calls fail (track successfulLogChecks) 3. Don't print raw pod logs on error match (may contain sensitive data) 4. Require explicit Available=True condition in deployment check 5. Restore os.Exit(testenv.Run(m)) in TestMain All issues identified by coworker review are now resolved. Tests compile cleanly with no errors. Co-Authored-By: Claude Sonnet 4.5 <noreply@anthropic.com>
E2E Test Fixes ✅Fixed all correctness and safety issues identified in code review:
Tests compile cleanly: Security Test Note

@dlom The Issue DetailsThe Snyk security scan is flagging Go standard library vulnerabilities in the CI environment's Go 1.26.4, which are fixed in Go 1.26.5:
These vulnerabilities affect 1,884 paths across 1,762 dependencies — all rooted in the Go toolchain version, not application code. Application Code Status✅ 0 application vulnerabilities found RequestThis is a CI infrastructure issue that affects the build environment, not this PR's changes. Could you please override the security check or advise on next steps? The K8s 1.36 upgrade code changes are unrelated to these Go stdlib CVEs. All other tests (unit, e2e, verify) are passing or in progress. Thanks! |
Applied patch from coworker review with improvements: - Use operationCtx consistently (don't shadow ctx parameter) - Use strings.Contains from stdlib instead of custom helpers - Rename successfulLogChecks to inspectedLogs for clarity - Update error messages to be more specific - Remove unnecessary custom contains() helper functions All changes from cco-1066-e2e-review.patch applied. Tests compile cleanly. Co-Authored-By: Claude Sonnet 4.5 <noreply@anthropic.com>
