Current CI setup (3345b02)

Removed make install-hooks from CI: direct pre-commit run does not require Git-hook registration. Pip still installs the pinned executable; the compatibility-keyed environment cache, Go setup in all ten repos and API-only generation remain. Earlier registration notes below describe superseded commits.

Validated direct execution in a fresh repo with neither Git hook installed, plus actionlint, structural and selected-file checks. Runtime success of older commits is not assumed for this new head.


What

Add .github/workflows/pre-commit.yml, using a shared baseline across the ten Go repos, with the documented API-only generation exception:

  • Run on pull_request with read-only contents permission and non-persistent checkout credentials.
  • Full-SHA pinned checkout/setup-go/setup-python actions; Go selected from go.mod and pre-commit pinned to the locally tested version.
  • Cache Go modules/build data using available root/tool-module checksum files.
  • Only the API workflow runs make generate-all before hooks; the other nine omit the generation step. All ten retain Go setup for formatting, vet and the pinned linter.
  • Run pre-commit run --all-files --show-diff-on-failure, with CGO disabled for hook tooling, a 30-minute timeout and stale-run cancellation.

Prow remains the merge gate. This is a secondary, non-required check; no branch-protection or required-check settings are changed. No application build or test command is added to GitHub Actions.

Important limitations

This minimal workflow does not execute commit-msg. Prow PR-title coverage gaps are tracked in HYPERFLEET-1817.

The pinned LeakTK Git hook scans staged changes, which a clean CI checkout lacks. Its passing is not evidence of secret scanning of PR content. Effective reusable CI scanning belongs to HYPERFLEET-1819; the native-scanner prototype is not included here. Hook selection remains the repo config, so this workflow does not add missing scanners/hygiene hooks to Broker.

Validation

  • actionlint v1.7.12 and YAML lint: passed.
  • Structural checks: only pull_request, read-only permission, credentials not persisted, full action SHAs, Go from go.mod, and a shared baseline differing only by the API generation step.
  • Local pre-commit run --all-files --show-diff-on-failure with Go 1.26.0 / CGO_ENABLED=0: passed. This is hook execution evidence, not a claim of complete secret or commitlint coverage.
  • No runtime source changes. Application integration/live E2E suites were not rerun for this workflow-only change.

Actual green GitHub Actions runs, merge and the next EPD has_ci_workflows observation remain acceptance checks.

Ticket: HYPERFLEET-1806.

Review/setup follow-up

New signed commit d78b6c1: workflow-level permissions: {} denies permissions by default; only jobs.pre-commit.permissions.contents: read grants repository read access. The pre-commit executable is still installed via pip, then make install-hooks registers the project’s Git hooks before execution. All ten workflows remain byte-identical (SHA-256 ea05d2aa6164637832b6d1a3ff69e520bc71ae1eaee8827af579130495e80ed8). actionlint, config checks, make install-hooks and full local hook runs passed again. Runtime results on earlier commit SHAs do not establish success of these new heads.

API-only generation exception (current design)

New signed commit 61d99d8 implements the agreed exception: only API has an explicit make generate-all step. The other nine workflows contain no generation step or Makefile grep. All ten retain actions/setup-go with go-version-file: go.mod and dependency caching, because Go is needed by gofmt/go vet/golangci-lint and hook environments independently of generation. The ticket acceptance criterion and architecture docs now reflect this exception; earlier byte-identical-all-ten notes/hashes above describe superseded commits.

Validation: actionlint and selected-file pre-commit checks passed for the updated workflows; docs Markdown/YAML lint passed. Structural comparison confirms the workflows are identical after removing only API generation, and the other nine files are byte-identical. Fresh runtime results must match these new commit SHAs.

Pre-commit environment cache

New signed commit 649186f adds a dedicated ~/.cache/pre-commit cache keyed by OS/architecture, effective Go/Python versions, PRE_COMMIT_VERSION and the config hash; no broad restore-key fallback. The pre-commit pin is defined once and shared by pip and the cache key. The API-only generation exception remains the only workflow difference. actionlint, YAML/structural checks and selected-file hooks passed; actual cache hits/time savings still require runtime evidence.

📝 Summary

Summary by CodeRabbit

  • Chores
    • Added automated pre-commit checks for pull requests.
    • Displays failure differences to make formatting and validation issues easier to review.
    • Automatically prepares required tooling and runs code generation when available before validation.

The pull-request workflow runs on Ubuntu 24.04 with read-only repository permissions and per-reference concurrency cancellation. It sets up Go and Python 3.12, installs pinned pre-commit tooling and hooks, conditionally runs make generate-all when the target exists, and executes all hooks with failure diffs enabled.

Full details: Docstring Coverage

Explanation

No functions found in the changed files to evaluate docstring coverage. Skipping docstring coverage check. Docstring coverage is scoped to functions touched by this diff. Analyzed 0 functions across 0 files. (1 skipped: 1 unsupported.)

Full details: Sec-02: Secrets In Log Output

Explanation

The pull request adds only .github/workflows/pre-commit.yml. The changed file contains no slog, logr, zap, or fmt.Print* log statement and no credential, token, password, or secret used as a log field or interpolated string. CWE/CVE: none applicable.

Full details: No Hardcoded Secrets

Explanation

No hardcoded secret is introduced. The only secret-like strings are full-length hexadecimal GitHub action commit SHAs at .github/workflows/pre-commit.yml:22, :27, and :35; these are immutable action references, not base64 secrets. The workflow contains no API key, token, password, private key, embedded credentials, or string assignment to a sensitive variable.

Full details: No Weak Cryptography

Explanation

No weak cryptography is introduced. The PR adds only .github/workflows/pre-commit.yml; it contains no banned primitive, custom cryptographic implementation, or secret comparison. The workflow invokes existing pre-commit hooks through make install-hooks, but the hook configuration and Makefile are unchanged and contain no matching weak-crypto usage.

Full details: No Injection Vectors

Explanation

No injection pattern from the check is introduced. The PR changes only .github/workflows/pre-commit.yml; it adds fixed commands and a grep condition at lines 39-49, with no SQL construction, exec.Command/exec.CommandContext, template.HTML(), or yaml.Unmarshal(). The workflow's github.ref value is used only for the concurrency group at line 9.

Full details: No Privileged Containers

Explanation

PASS: The pull request changes only .github/workflows/pre-commit.yml. It adds no Kubernetes/OpenShift manifest, Helm template, or Dockerfile. The workflow is a test/CI configuration and contains none of the specified privileged-container settings. No CWE/CVE applies.

Full details: No Pii Or Sensitive Data In Logs

Explanation

PASS — The pull request adds only .github/workflows/pre-commit.yml. Its steps install tools, generate sources, and run pre-commit; it adds no slog, logr, zap, log, or fmt.Print* logging statement. The reviewed file contains no PII, session ID, raw request/response logging, or hostname-with-credentials logging (head d78b6c1, lines 1-53).

Move contents: read to the pre-commit job (CWE-284).

The current job needs read access, but workflow-level permissions also apply to any job added later. Set the permission under jobs.pre-commit instead. (docs.github.com)

As per path instructions, “Set least-privilege permissions per job, not workflow level.”

Temporarily closing and immediately reopening, explicitly authorized by Rafael, to re-emit pull_request.reopened while diagnosing the missing pre-commit Actions run. No commits, workflow settings or permissions are changed and no merge is performed. The API control experiment is documented in openshift-hyperfleet/hyperfleet-api#407; we are testing reopen alone here, without an internal diagnostic branch.

The cache step only saves on success, so any run where the hooks fail throws away the environments it just built, and failing on unformatted code is this check's normal outcome, so fix-and-repush cycles rebuild from scratch every time. Consider splitting it into actions/cache/restore + actions/cache/save with if: always() per the upstream docs.

Closing without merge following the team discussion on HYPERFLEET-1806. EPD now supports Prow, so the need for a parallel GitHub Actions pre-commit check will be reconsidered during the epic review. This work is paused pending that review; Prow remains the merge gate. The branch is retained for reference.
