Fix in prowgen to respect capabilities

[jmguzik]

Summary

prowgen now respects image capabilities when it generates test jobs. It derives capabilities from required project images, including indirect image dependencies, cluster profiles, release payloads, and multi-stage test configurations.

The logic excludes pull-spec dependencies and overridden dependencies. It also handles optional images and built images in release configurations.

Generated presubmit jobs now receive the correct capability labels, including propagated capabilities such as arm64. Tests cover dependency propagation, exclusions, optional image chains, and cluster-profile and release-based tests.

Pipeline controller notification
This repo is configured to use the pipeline controller. Second-stage tests will be triggered either automatically or after lgtm label is added, depending on the repository configuration. The pipeline controller will automatically detect which contexts are required and will utilize /test Prow commands to trigger the second stage.

For optional jobs, comment /test ? to see a list of all defined jobs. To trigger manually all jobs from second stage use /pipeline required command.

This repository is configured in: automatic mode

Test job capability derivation

Layer / File(s)	Summary
Resolve capabilities from required images pkg/prowgen/prowgen.go, pkg/prowgen/prowgen_test.go	Capability resolution follows direct and recursive image dependencies. It excludes pull-spec overrides and optional images when appropriate. It handles cluster profiles and release configurations.
Propagate capabilities to generated jobs pkg/prowgen/prowgen.go, pkg/prowgen/prowgen_test.go	Generated test jobs receive resolved capabilities. Tests verify dependency-specific capabilities and arm64 propagation for cluster-profile tests.

Estimated code review effort: 4 (Complex) | ~45 minutes

Merge Risk: 🟡 Moderate · up to caaa6

Generated jobs can receive unnecessary constrained-pool capability labels for releases that exclude built images, potentially reducing scheduling availability. Release identity and IncludeBuiltImages handling should be corrected before merge.

Full details: Go Error Handling

Explanation

PASS. The changed production code introduces no unchecked error return. DependencyParts returns (stream string, name string, explicit bool), so the discarded third value is a boolean, not an error. The existing NewProwJobBaseBuilderForTest error is checked and wrapped with %w. The new pointer dereferences have guards or valid local invariants: ClusterClaim, multi-stage pointers, LiteralTestStep, and release integration are checked; image pointers are inserted only from config.Images.Items and are checked during dependency traversal. No new panic call is present.

Full details: Test Coverage For New Features

Explanation

The pull request adds unit coverage for the new capability derivation. TestProjectImageCapabilitiesForTest covers direct and transitive image dependencies, cluster-profile selection, optional-image exclusion, release configurations, inline and literal multi-stage configurations, and case-insensitive pull-spec overrides. TestGenerateJobsPropagatesDependentImageCapabilities and TestGenerateJobsPropagatesArm64ImageCapabilityToClusterProfileTest verify the changed GenerateJobs behavior and provide regression coverage that would fail without the new capability injection.

Full details: Stable And Deterministic Test Names

Explanation

The pull request adds only Go testing tests, not Ginkgo tests. The new Test... names are fixed identifiers. The t.Run(tc.name, ...) subtest names come from a table of literal, static strings such as cluster profile requires all non-optional images and release without built images does not select image builds. No added title contains a pod name, timestamp, UUID, node, namespace, IP address, or other run-dependent value.

Full details: Test Structure And Quality

Explanation

The added tests are standard Go unit tests, not Ginkgo tests. They exercise pure capability derivation and generated in-memory job configuration. They create no cluster resources, call no cluster APIs, and use no Eventually or Consistently waits. Assertions include diagnostic messages, and each table subtest targets one capability-selection case; the job-generation tests verify one related propagation behavior. No custom-check failure condition is introduced.

Full details: Microshift Test Compatibility

Explanation

PASS — The pull request adds capability-derivation logic and standard Go unit tests in pkg/prowgen. The test file imports testing and contains Test... functions. It adds no Ginkgo constructs such as It, Describe, Context, or When, and it adds no e2e test. Therefore, the MicroShift Test Compatibility check is not applicable.

Full details: Single Node Openshift (Sno) Test Compatibility

Explanation

PASS — The pull request changes only pkg/prowgen/prowgen.go and Go unit tests in pkg/prowgen/prowgen_test.go. The added tests use testing.T (Test... functions), not Ginkgo It, Describe, Context, or When. They do not add cluster tests or multi-node/HA assumptions. The SNO check is therefore not applicable.

Full details: Topology-Aware Scheduling Compatibility

Explanation

PASS: The pull request changes only pkg/prowgen/prowgen.go and its tests. The implementation adds capability labels to generated Prow jobs. It does not add or modify deployment manifests, operator code, controllers, replicas, affinity, topology spread, node selectors, tolerations, or PDBs. The topology-aware scheduling check is therefore not applicable.

Full details: Ote Binary Stdout Contract

Explanation

PASS: The pull request changes only pkg/prowgen/prowgen.go and its tests. The added code derives capabilities and labels; it adds no fmt.Print*, log.Print*, klog, os.Stdout, Ginkgo suite setup, TestMain, or init writes. pkg/prowgen is a library package, not an OTE binary entry point. No process-level stdout contract violation was introduced.

Full details: Ipv6 And Disconnected Network Test Compatibility

Explanation

PASS — The pull request adds standard Go unit tests (func Test...(t *testing.T)) in pkg/prowgen/prowgen_test.go, not new Ginkgo e2e tests. No It, Describe, Context, or When declarations were added. The quay.io value is only a dependency-override test fixture; the tests do not connect to or pull from it.

Full details: No-Weak-Crypto

Explanation

PASS — The commit adds capability-selection logic and tests only. The diff adds no MD5, SHA1, DES, 3DES, RC4, Blowfish, or ECB usage. It adds no cryptographic implementation and no secret or token comparisons. The only new standard-library import is strings, used for case-insensitive dependency-name matching.

Full details: Container-Privileges

Explanation

PASS. The pull request changes pkg/prowgen to add capability/<name> job labels derived from project-image metadata. The exact commit additions contain no privileged, hostPID, hostNetwork, hostIPC, SYS_ADMIN, allowPrivilegeEscalation, or security-context fields. The repository shows these labels are scheduler metadata consumed by the dispatcher, not Kubernetes container security settings. Existing privileged test data is unchanged.

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

Explanation

PASS: The pull request adds no production logging calls, logger imports, or print statements. The new code derives capabilities and writes them to Prow job labels; it does not log them. The only new test diagnostics use fixed capability labels and values. No added code formats passwords, tokens, API keys, PII, session IDs, hostnames, or customer data for logs.
