Walkthrough

The PR updates github.com/stretchr/testify, Helm, and go.yaml.in/yaml/v3. It adds github.com/ProtonMail/go-crypto and github.com/cloudflare/circl as indirect dependencies.

Changes

Go module dependency updates

Layer / File(s) Summary
Update module dependencies
go.mod
Helm is upgraded to v3.21.4. Testify and YAML are also upgraded. The module adds two indirect dependencies: github.com/ProtonMail/go-crypto v1.4.1 and github.com/cloudflare/circl v1.6.3.

Estimated code review effort: 1 (Trivial) | ~2 minutes

Merge Risk: 🟠 High · up to 962d2

This dependency upgrade is associated with YAML manifest splitting that can misinterpret an indented --- inside a literal block, producing truncated or mismatched manifests and potentially incorrect deployments; the PR is not merge-ready until the parser is corrected and a regression fixture is added.

Suggested reviewers: fgiudici, joelanford, rashmigottipati

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: Stable And Deterministic Test Names

Explanation

PASS: The pull request does not add or modify any test files or Ginkgo test titles. The diff changes go.mod, go.sum, and vendored Helm/dependency production code only. Repository searches found no Ginkgo declarations, so this check has no introduced unstable or overly specific test name to flag.

Full details: Test Structure And Quality

Explanation

PASS. The pull request changes dependency metadata and vendored dependency files only. It does not add or modify repository Ginkgo tests, It blocks, setup/cleanup hooks, cluster operations, waits, or assertions. The changed vendored *_test_data.go and test-vector files contain fixture data, not Ginkgo test code. Therefore the custom check is not applicable.

Full details: Microshift Test Compatibility

Explanation

PASS: The pull request changes only dependency metadata and vendored dependency files. The committed diff has no new or modified repository e2e/test source outside vendor, and no added Ginkgo declarations. Therefore, the MicroShift compatibility check is not applicable.

Full details: Single Node Openshift (Sno) Test Compatibility

Explanation

The check is not applicable. The PR commit changes only go.mod, go.sum, and vendored dependency files. It adds or modifies no repository Go tests, Ginkgo declarations, or OpenShift e2e test paths. Therefore, it introduces no SNO multi-node test assumption.

Full details: Topology-Aware Scheduling Compatibility

Explanation

PASS: The PR changes only go.mod, go.sum, vendor/modules.txt, and vendored dependency files. The vendored Helm hunks update file handling and OpenPGP imports; they add no deployment manifests, operator/controller logic, or scheduling constraints. The patch contains no anti-affinity, topology spread, replica, node selector, taint, toleration, or PDB changes.

Full details: Ote Binary Stdout Contract

Explanation

PASS. The pull request changes only dependency metadata and vendored Helm/crypto code. The application command and package code have no pull-request changes. The only direct stdout writes in changed source are in vendor/github.com/cloudflare/circl/math/fp448/fuzzer.go, a FuzzReduction function guarded by //go:build gofuzz; it is not main, init, TestMain, a suite hook, or RunSpecs setup. The repository builds cluster-olm-operator and contains no OTE/OpenShift test binary or Ginkgo suite. Existing fmt.Println and klog calls in cmd/cluster-olm-operator/main.go are unchanged and therefore cannot establish pull-request causality.

Full details: Ipv6 And Disconnected Network Test Compatibility

Explanation

PASS — The pull request changes only go.mod, go.sum, and vendored dependency files. The diff adds or modifies no Ginkgo tests, e2e tests, or test declarations. The custom check is therefore not applicable.

Full details: No-Weak-Crypto

Explanation

The PR adds and wires vendored OpenPGP code that uses prohibited weak algorithms. vendor/github.com/ProtonMail/go-crypto/openpgp/internal/algorithm/cipher.go imports crypto/des, exposes TripleDES, and calls des.NewTripleDESCipher. The added OpenPGP code also imports crypto/sha1, exposes SHA-1 support, and uses SHA-1 for legacy private-key checks and MDC processing. Helm provenance now imports this package, and its DecryptKey path can reach the legacy cipher implementation. The detached-signature path also explicitly permits SHA-1. These are changed files introduced by the dependency migration, not only pre-existing application code.

Resolution

Use an OpenPGP dependency and configuration that do not include or dispatch DES/3DES or SHA-1. Reject SHA-1 signatures and legacy encrypted keys, and use AES/AEAD with strong hashes for supported operations. Remove the weak legacy implementation from the vendored build or isolate it from production paths. Use crypto/subtle.ConstantTimeCompare for any comparison that validates a secret or token.

Full details: Container-Privileges

Explanation

PASS: The pull request changes only Go dependency metadata and vendored Go sources. It does not add or modify any Dockerfile, Kubernetes manifest, or Helm manifest. The existing Dockerfile sets USER 1001, and the existing Deployment sets runAsNonRoot: true and allowPrivilegeEscalation: false; no privileged: true, host namespace settings, or SYS_ADMIN capability are present. The relevant files are unchanged from the parent commit.

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

Explanation

PASS. The pull request changes dependency metadata and vendored dependency code only. The Helm changes update empty-file handling and OpenPGP imports; they add no logging. A diff search found no added application logging or logs of passwords, tokens, API keys, PII, session IDs, hostnames, or customer data. The only new fmt.Printf calls are in a //go:build gofuzz mathematical fuzzer and print generated test values.

Hi @dependabot[bot]. Thanks for your PR.

I'm waiting for a openshift member to verify that this patch is reasonable to test. If it is, they should reply with /ok-to-test on its own line. Until that is done, I will not automatically test new commits in this PR, but the usual testing commands by org members will still work.

Regular contributors should join the org to skip this step.

Once the patch is verified, the new status will be reflected by the ok-to-test label.

I understand the commands that are listed here.

Fix YAML document splitting before upgrading Helm.

splitYAMLDocuments treats an indented --- inside a literal block scalar as a document separator. A two-document stream can produce three parts, causing truncated or mismatched manifest files. Use YAML-aware document boundaries and add a regression fixture.

only still-valid issues, skip the rest with a brief reason, keep changes
minimal, and validate.

In `@go.mod` at line 21, Update splitYAMLDocuments to recognize document
separators only at valid YAML document boundaries, excluding indented --- lines
within literal block scalars; add a regression fixture covering a two-document
stream with such content and verify it produces exactly two complete manifests
before upgrading Helm.
