Summary

  • Adds Overridable to api.StepParameter: a step author can explicitly opt a specific declared parameter into being overridden at trigger time (e.g. by a Gangway CreateJobExecution caller via pod_spec_options.envs).
  • Adds ParamOverrides to api.MultiStageTestConfigurationLiteral, populated by ci-operator from the environment, and only ever applied to parameters that set Overridable: true - and scoped per-step, so a same-named parameter on a different, non-opted-in step never receives it.
  • Supports two forms of trigger-time override, so callers no longer need the MULTISTAGE_PARAM_OVERRIDE_<NAME> prefix workaround (and refs/scripts no longer need to declare a duplicate, prefixed parameter and manually reassign it):
    • the parameter's own plain name (e.g. EVAL_MODEL=foo), honored only if that parameter opted in
    • the legacy MULTISTAGE_PARAM_OVERRIDE_<NAME> form, kept for backwards compatibility and taking precedence if both are present
  • No behavior change for parameters that don't set Overridable: true.

Made with Cursor

Summary

ci-operator now supports trigger-time parameter overrides for multi-stage test steps.

  • Parameters opt in with StepParameter.Overridable.
  • Overrides support plain parameter names and the legacy MULTISTAGE_PARAM_OVERRIDE_<NAME> format.
  • Legacy prefixed variables take precedence.
  • Overrides apply only to opted-in parameters and remain isolated per step.
  • Non-overridable parameters keep their existing behavior.
  • Resolved-configuration logging redacts override values.
  • Tests cover opt-in behavior, precedence, default handling, redaction, and cross-step isolation.

📝 Walkthrough

Walkthrough

Changes

Trigger-time parameter overrides now support legacy prefixed and declared plain environment variables. Multi-stage configurations store these overrides and apply them only to parameters marked Overridable. Tests cover precedence, defaults, value preservation, and cross-step isolation.

Parameter override flow

Layer / File(s) Summary
Override contract and multi-stage wiring
pkg/api/types.go, pkg/steps/multi_stage/multi_stage.go
Adds StepParameter.Overridable and MultiStageTestConfigurationLiteral.ParamOverrides. Multi-stage steps copy parameter overrides during construction.
Environment override collection
cmd/ci-operator/main.go, cmd/ci-operator/main_test.go
Collects prefixed and declared plain-name overrides. Prefixed values take precedence. Tests cover recognized names, equal-sign values, and rejection of non-overridable names.
Multi-stage parameter application
pkg/steps/multi_stage/gen.go, pkg/steps/multi_stage/gen_test.go
Applies overrides only to overridable parameters. Tests cover defaults, precedence, and cross-step isolation.

Estimated code review effort: 3 (Moderate) | ~20 minutes

Merge Risk: ⚪ Minimal · up to f7ac7

The change adds explicitly opt-in, step-scoped trigger-time parameter overrides while preserving existing behavior for non-overridable parameters; no actionable merge-blocking risk remains beyond normal checks and review.

Full details: Go Error Handling

Explanation

PASS. The pull request adds no ignored error returns, new panic calls, or unwrapped error paths. The new pointer access checks ms == nil before use, and generated deepcopy code checks ParamOverrides before dereferencing it. Existing _ assignments and panic calls are outside the added logic. The new map lookups are nil-safe in Go.

Full details: Test Coverage For New Features

Explanation

Coverage is present for the new override behavior. TestApplyEnvOverrides covers legacy prefixed variables, equal-sign values, plain opted-in and rejected names, observer parameters, and prefixed-over-plain precedence. TestGeneratePodsOverrideEnvironment covers opt-in enforcement, defaults, and override precedence. TestGeneratePodsOverrideEnvironmentCrossStepIsolation is a regression test for the non-leakage fix. The new helper is exercised through TestApplyEnvOverrides; generated-file changes require no additional tests.

Full details: Stable And Deterministic Test Names

Explanation

The patch adds only standard Go tests. It adds no Ginkgo It, Describe, Context, or related titles. New t.Run names use static string literals such as plain name honored for an opted-in parameter and override is applied to an opted-in parameter. No title contains a generated value, timestamp, node, namespace, pod name, IP address, or identifier.

Full details: Test Structure And Quality

Explanation

PASS: The pull request adds or updates only Go tests using the standard testing package. The changed files contain no Ginkgo It, BeforeEach, AfterEach, Eventually, or Consistently blocks. The tests construct pod objects in memory and do not create cluster resources or perform indefinite waits. The Ginkgo-specific check is therefore inapplicable.

Full details: Microshift Test Compatibility

Explanation

PASS — The pull request adds only standard Go unit tests (TestApplyEnvOverrides, TestGeneratePodsOverrideEnvironment, and related tests). No new Ginkgo It, Describe, Context, or When tests were added, and the changed test lines contain no MicroShift-incompatible APIs or resources. The custom check is therefore not applicable.

Full details: Single Node Openshift (Sno) Test Compatibility

Explanation

PASS: The pull request adds only standard Go unit tests (func Test... using testing.T) in cmd/ci-operator/main_test.go and pkg/steps/multi_stage/gen_test.go. It adds no Ginkgo It, Describe, Context, or When e2e test. The complete diff contains no multi-node or HA assumptions covered by this check.

Full details: Topology-Aware Scheduling Compatibility

Explanation

PASS — The pull request does not add or modify deployment scheduling constraints. The implementation changes environment parsing, API parameter fields, and multi-stage pod environment generation. The focused diff contains no node selectors, node affinity, anti-affinity, topology spread constraints, replica logic, tolerations, or PDB changes. Therefore, the topology-aware scheduling check is not applicable.

Full details: Ote Binary Stdout Contract

Explanation

The pull request does not add or alter any process-level stdout write. Its changed code only parses environment variables, stores ParamOverrides, and applies values to generated pod environments. The diff adds no fmt.Print*, os.Stdout, Ginkgo setup, or logging calls. Existing stdout logging and klog.LogToStderr(false) in cmd/ci-operator/main.go are unchanged and therefore are not caused by this pull request.

Full details: Ipv6 And Disconnected Network Test Compatibility

Explanation

PASS: The pull request adds only standard Go unit tests (func Test... using testing.T) in cmd/ci-operator/main_test.go and pkg/steps/multi_stage/gen_test.go. It adds no Ginkgo e2e tests. The added tests construct in-memory pod specifications and environment maps, with no IPv4 assumptions or external connectivity.

Full details: No-Weak-Crypto

Explanation

PASS — The pull request adds environment override handling, API fields, and parameter propagation only. The exact diff introduces no MD5, SHA-1, DES/3DES, RC4, Blowfish, ECB, custom cryptography, or secret/token comparisons. The existing crypto/sha256 import is unchanged from the parent revision.

Full details: Container-Privileges

Explanation

PASS: The pull-request diff adds parameter override fields and environment-handling logic only. The complete added-line scan found zero matches for privileged, hostPID, hostNetwork, hostIPC, SYS_ADMIN, allowPrivilegeEscalation, runAsUser, runAsNonRoot, securityContext, or capabilities. Existing security-context code in pkg/steps/multi_stage/gen.go is unchanged. No changed manifest introduces a listed privilege condition.

Full details: No-Sensitive-Data-In-Logs

Explanation

No changed code logs override values. applyEnvOverrides only stores environment values in Environment and ParamOverrides, and generateParams places opted-in values into pod environment variables. The existing verbose Resolved configuration trace runs before applyEnvOverrides, so it does not serialize the new values. Other changed production paths contain no value-bearing log statements. The legacy prefixed environment handling was already present.

Handle the YAML marshal error.

sigs.k8s.io/yaml.Marshal can return an error. The o.verbose branch discards it and may emit an empty configuration trace. Capture and log the error, then emit the trace only when marshaling succeeds.

Adds an Overridable flag on step parameters, so ci-operator can apply a
trigger-time environment variable override (e.g. from Gangway's
pod_spec_options.envs) to a normally-named parameter, without requiring
the ref/script boilerplate of declaring and reassigning a separate
MULTISTAGE_PARAM_OVERRIDE_<NAME> parameter. The legacy prefixed form is
still supported and takes precedence for backwards compatibility, and
overrides are only ever honored for parameters that explicitly set
Overridable: true, so unrelated parameters can't be tampered with.
