Description

Update the gateway Docker builder to Go 1.27 and refresh GitHub Actions to current released versions. Update gateway dependencies and vendored sources, including faas-provider, Prometheus, NATS and Go libraries. The updated dependencies require a Go 1.26 module minimum.

Construct expected Prometheus descriptors with NewDesc so the existing assertions retain coverage of metric names, help and labels while accommodating the library's updated diagnostic formatting.

Motivation and Context

Keep gateway builds and dependencies current.

How Has This Been Tested?

On Linux amd64 with Go 1.27.3:

• In gateway: go test ./..., go test -race ./..., go vet ./... and go mod verify passed.
• Root module: go mod verify passed; it has no packages or dependencies, so there are no root unit tests.
• No make dist target exists. Ran the Docker distribution build with docker buildx build --platform linux/amd64,linux/arm64,linux/arm/v7 --output type=oci,dest=/tmp/faas-validation/gateway.oci.tar gateway using an isolated builder. All three platforms passed, including the Dockerfile's license, formatting and native unit-test checks. This covers both workflow platforms and the additional ARMv7 platform in the gateway Makefile.
• Inspected the local OCI manifests and image configs for all three platforms, extracted each gateway binary, and confirmed the matching statically linked ELF architecture with file.
• ARM binaries were cross-compiled; unit tests ran on amd64. No running gateway/provider/NATS integration or target-architecture runtime tests were performed. Docker reports the existing redundant TARGETPLATFORM warning.

AI Pull Request Overview

Disclaimer: This review was generated by automated AI and may contain errors. Do not trust its outputs without human verification.

Summary

• Updates the gateway builder from Go 1.24 to Go 1.27 and raises the gateway module minimum to Go 1.26.
• Refreshes gateway dependencies and synchronizes checksums and vendored module metadata.
• Updates the build and publish workflows to newer major versions of their GitHub Actions.
• Reworks Prometheus descriptor assertions to remain stable across diagnostic string-format changes while preserving explicit metric expectations.
• Both new commits were inspected and contain no prohibited AI authorship or attribution indicators.
• No blocking correctness, compatibility, security, or workflow issues were identified in the scoped changes.

Approval rating (1-10)

9/10. The toolchain, dependency metadata, workflows, and adjusted assertions are internally consistent, with no concrete merge-blocking issue found.

Summary per file

Summary per file

File path	Summary
.github/workflows/build.yml	Updates checkout, QEMU, Buildx, and image-build actions to newer major versions.
.github/workflows/publish.yml	Updates checkout and Docker setup, login, and publishing actions to newer major versions.
gateway/Dockerfile	Moves the gateway build stage from Go 1.24 to Go 1.27.
gateway/go.mod	Raises the Go minimum to 1.26 and updates direct and indirect dependencies.
gateway/go.sum	Synchronizes dependency checksums with the updated module graph.
gateway/metrics/exporter_test.go	Constructs expected Prometheus descriptors through the library API instead of hard-coding diagnostic strings.

Overall Assessment

The final state is coherent: dependencies requiring Go 1.26 are reflected in the module directive, the Docker builder uses Go 1.27, and module checksums and vendoring metadata track the selected versions. The workflow updates preserve the existing build and publish configuration. The Prometheus test change avoids coupling assertions to an internal diagnostic representation without removing the explicit metric names, help text, or variable-label checks. No actionable defect was found.

Detailed Review

Detailed Review

No findings.

The dependency and toolchain changes are aligned across gateway/go.mod, gateway/go.sum, vendoring metadata, and gateway/Dockerfile. The GitHub Actions updates do not alter workflow inputs, permissions, platforms, or publication behavior. The revised metric descriptor assertions still compare independently specified descriptor fields against the descriptors emitted by the exporter.
