- Add validation in validateFlags() to enforce initialLogLevel is in [0,10] - Remove unsafe int8 cast in both main.go and enoexec-daemon/main.go - Update flag documentation to clarify CRD levels (0-3) with extended range (0-10) for advanced debugging - Addresses CodeRabbit review comments on cmd/main.go:326 and cmd/enoexec-daemon/main.go:42
Bug: The applyResources() function was using 'return nil' when encountering an empty resource, causing it to exit early and skip processing remaining resources in the ResMap. Changed to 'continue' to skip empty resources while processing all others. Addresses CodeRabbit review comment on suite_test.go:169-171.
Previously, when client.List() failed to retrieve PodPlacementConfigs, the webhook would set ppcList.Items = [] and continue mutating the pod (adding labels and scheduling gates). This violated fail-open semantics. Now returns the original unmodified pod when namespace config cannot be read, implementing true fail-open admission behavior. Addresses CodeRabbit review comment on scheduling_gate_mutating_webhook.go:84-90. Co-Authored-By: Claude Sonnet 4.5 <noreply@anthropic.com>
…tibility Making spec.plugins required in v1beta1 is a breaking change that would cause validation failures on existing PodPlacementConfig objects created without the plugins field. Changes: - Remove +kubebuilder:validation:Required marker - Add omitempty to json tag - Regenerate CRD to remove plugins from required array The code is already defensive - all accesses to Plugins use the PluginsEnabled() helper which has nil checks, so this is safe. Addresses CodeRabbit review comments on api/v1beta1/podplacementconfig_types.go:35-38 and config/crd/bases/multiarch.openshift.io_podplacementconfigs.yaml:92-96. Co-Authored-By: Claude Sonnet 4.5 <noreply@anthropic.com>
…bhook The ClusterPodPlacementConfig validator was not enforcing the singleton name requirement, allowing users to create resources with names other than "cluster". The controller only reconciles the singleton named "cluster", so other names would be ignored. Added validation to reject any ClusterPodPlacementConfig with a name other than "cluster" at admission time. Addresses CodeRabbit review comment on api/v1beta1/clusterpodplacementconfig_webhook.go:70-86. Co-Authored-By: Claude Sonnet 4.5 <noreply@anthropic.com>
The test was checking the informer cache synchronously with Expect() immediately after deletion. Since cache eviction is asynchronous, this could flake under slower envtest runs where the cache hasn't been evicted yet. Changed to Eventually() to wait for the cache to become empty, making the test more robust. Addresses CodeRabbit review comment on internal/controller/podplacementconfig/suite_test.go:138-140. Co-Authored-By: Claude Sonnet 4.5 <noreply@anthropic.com>
The test mutates the singleton ClusterPodPlacementConfig by setting FallbackArchitecture, but only reverts it at the end. If any assertion fails before cleanup, the modified state leaks into subsequent tests. Now using DeferCleanup to capture the original value and restore it even if the test fails, ensuring proper test isolation. Addresses CodeRabbit review comment on internal/controller/podplacement/pod_reconciler_test.go:119-187. Co-Authored-By: Claude Sonnet 4.5 <noreply@anthropic.com>
Previously, NotFound errors (pod/node deleted before event processed) were counted as successful reconciliations, making it hard to track cleanup vs actual success vs errors. Added new metric mto_enoexecevents_stale_total to track events referencing objects that no longer exist. Now the three metrics are: - mto_enoexecevents_total: Successfully processed events - mto_enoexecevents_stale_total: Events for deleted pods/nodes (cleanup) - mto_enoexecevents_invalid_total: Real reconciliation errors This provides better visibility into the different event outcomes. Addresses CodeRabbit review comment on internal/controller/enoexecevent/handler/enoexecevent_controller.go:97-109. Co-Authored-By: Claude Sonnet 4.5 <noreply@anthropic.com>
The deleteErroredENoExecEvents function was logging delete errors but not returning them. The caller (handleEnoexecDelete) would continue tearing down resources and finalizers even if errored ENoExecEvent objects still existed. Changed function signature to return error, aggregate delete errors, and propagate them to the caller. This ensures cleanup is blocked when deletes fail, preventing finalizer deadlocks. Updated all callers including tests to handle the new error return. Addresses CodeRabbit review comment on internal/controller/operator/clusterpodplacementconfig_controller.go:945-970. Co-Authored-By: Claude Sonnet 4.5 <noreply@anthropic.com>
The upgrade automation README documented using raw 'go mod vendor', which bypasses the repository's supported entrypoint. Updated to use 'make vendor' instead, which respects GOFLAGS=-mod=vendor and the repo's vendoring workflow. Addresses CodeRabbit review comment on hack/upgrade-automation/README.md:78-86. Co-Authored-By: Claude Sonnet 4.5 <noreply@anthropic.com>
The fallback k8s version discovery was extracting only the minor version (e.g., 34 from v0.34.1) and emitting "1.34.0", which drops the patch version. Now captures the full module version (v0.34.1) and transforms it to 1.34.1, preserving the patch number for accurate version matching. Addresses CodeRabbit review comment on hack/upgrade-automation/scripts/lib/version-discovery.sh:25-31. Co-Authored-By: Claude Sonnet 4.5 <noreply@anthropic.com>
The release discovery was including -alpha, -beta, and -rc tags from GitHub releases. If a prerelease was the newest compatible version, the upgrade would pin unstable controller-runtime, controller-tools, or golangci-lint versions. Added grep filter to exclude prerelease tags across all discovery functions (controller-runtime, controller-tools, golangci-lint). Addresses CodeRabbit review comment on hack/upgrade-automation/scripts/lib/version-discovery.sh:142-159, 209-226, 295-304. Co-Authored-By: Claude Sonnet 4.5 <noreply@anthropic.com>
The script was detecting when vendoring upgraded the go directive (because dependencies require it), then forcibly downgrading it back. This produces a go.mod that misstates the actual minimum toolchain and can hide broken upgrades. Now errors out when dependencies require a higher Go version, preventing silently invalid module files. Addresses CodeRabbit review comment on hack/upgrade-automation/scripts/upgrade.sh:519-529. Co-Authored-By: Claude Sonnet 4.5 <noreply@anthropic.com>
This commit addresses four critical issues in the upgrade automation scripts: 1. Prerequisites validation never runs (outrigger-project#14): - Added validate_golang_image_exists() call to verify golang image exists - Added validate_k8s_version_consistency() call to check k8s.io/* versions - Both validations now run before creating upgrade branch 2. GNU-specific grep patterns (macOS incompatible) (outrigger-project#15): - Replaced all grep -P (Perl regex) with sed -E (POSIX extended regex) - Replaced \K lookahead assertions with sed capture groups - Affected lines: version-discovery.sh:28, 78, 117, 154, 204, 221 - Scripts now work on both Linux (GNU) and macOS (BSD) 3. Unconditional git commits fail on re-runs (outrigger-project#17): - Added git status --porcelain checks before commits in Step 1 and 2 - Steps 3/4 always have changes (go.mod/vendor updates) - Steps 5/6 already had conditional commits - Script can now be re-run without failing on unchanged files 4. Skips make vendor and quality checks (outrigger-project#18): - Replaced raw 'go mod vendor' with 'make vendor' in Step 4 - Added 'make fmt' and 'make goimports' before 'make test' in Step 6 - Auto-fixes formatting issues before running validation - Ensures all Makefile targets and quality checks are used These fixes improve script reliability, cross-platform compatibility, re-runability, and adherence to project build standards.

Only kube-* namespaces are hardcoded as always excluded. Other system namespaces (openshift-*, hypershift-*) can be included or excluded via the namespaceSelector configuration in ClusterPodPlacementConfig. This documentation was incorrectly stating that all three namespace patterns were always excluded, which conflicted with the actual implementation in shouldIgnorePod() at pod_model.go:435. Fixes incorrect documentation identified in CodeRabbit review comment: openshift#183 (comment) Co-Authored-By: Claude Sonnet 4.5 <noreply@anthropic.com>
Changed 'faled' to 'failed' and improved grammar in the help string. Metric help text is displayed in Prometheus/Grafana dashboards and used by operators for monitoring, so correct spelling is important. Co-Authored-By: Claude Sonnet 4.5 <noreply@anthropic.com>
Changed 'caCopyright' to 'Copyright' in the Apache 2.0 license header. Copyright notices must be formatted correctly for legal compliance. Co-Authored-By: Claude Sonnet 4.5 <noreply@anthropic.com>
Added 'text' language tags to fenced code blocks for branch naming example and error output snippets. This fixes markdownlint MD040 warnings and enables proper syntax highlighting in documentation viewers. Co-Authored-By: Claude Sonnet 4.5 <noreply@anthropic.com>
Added documentation to clarify that pullSecretDataList intentionally returns nil error even when pull secrets fail to retrieve or parse. This fail-open design allows image inspection to proceed without authentication rather than blocking pod scheduling due to transient pull secret issues. Addresses CodeRabbit concern about error handling - this is intentional behavior, not a bug. Co-Authored-By: Claude Sonnet 4.5 <noreply@anthropic.com>
The cache-backed ClusterPodPlacementConfig value needs time to update after resource deletion. Change synchronous Expect to Eventually to prevent test flakiness. Co-Authored-By: Claude Sonnet 4.5 <noreply@anthropic.com>

Tests with only TODO comments currently show as passing without testing anything. Use PIt() instead of It() to mark them as pending so they're clearly identified as unimplemented and excluded from test pass counts. Affected tests: - handles images with global pull secrets correctly - handles images with local pull secrets correctly - handles node affinity as intersection of multi-arch images - handles node affinity of multi-arch and single-arch images Co-Authored-By: Claude Sonnet 4.5 <noreply@anthropic.com>
Without defer GinkgoRecover(), panics or assertion failures inside goroutines that start the controller manager are not captured by Ginkgo, causing test suite crashes instead of proper failure reporting. Add defer GinkgoRecover() as the first statement in both podplacement and podplacementconfig suite_test.go manager startup goroutines to ensure Ginkgo properly handles failures. Co-Authored-By: Claude Sonnet 4.5 <noreply@anthropic.com>
Combining declaration and assignment (local var=$(cmd)) masks the command's exit code. If mktemp fails, the script continues with an empty variable instead of failing fast. Separate the declaration and assignment, and add explicit error handling to catch mktemp failures. Addresses ShellCheck SC2155. Co-Authored-By: Claude Sonnet 4.5 <noreply@anthropic.com>
Add nolint comment for G115 gosec warning on int8 conversion at cmd/main.go:331. The conversion is safe because initialLogLevel is validated to be in range [0,10] by validateFlags(), so -initialLogLevel is guaranteed to be in range [-10,0] which fits in int8 range [-128,127].

Prevent potential nil pointer dereference when ClusterPodPlacementConfig is not available. When cppc is nil, treat it as if the NodeAffinityScoring plugin is disabled since there's no configuration to enable it. Co-Authored-By: Claude Sonnet 4.5 <noreply@anthropic.com>
Add nolint directive for unexported status fields that have json:"-" tags. While Go linters typically flag struct tags on unexported fields as redundant, controller-gen (the Kubernetes CRD generator) requires JSON tags on ALL fields in API types, including unexported ones. This resolves the conflict between standard Go linting rules and controller-gen requirements, with an explanatory comment documenting the justification.
…Monitor Replace the deprecated BearerTokenFile field with the modern Authorization field in ServiceMonitor configuration. The new Authorization API automatically uses the default service account token from the same path, maintaining identical behavior while following Prometheus Operator best practices. This change is compatible with prometheus-operator v0.86.2 and later. Co-Authored-By: Claude Sonnet 4.5 <noreply@anthropic.com>
Replace the deprecated fake.NewSimpleClientset() with fake.NewClientset() in test utilities. Both functions have identical behavior, but NewClientset is the recommended API in newer versions of client-go. Co-Authored-By: Claude Sonnet 4.5 <noreply@anthropic.com>
