v0.3.1 - 2020-08-23

Added

  • Docker-based GitHub Actions Workflows

    • Replace native GitHub Actions with containers created and managed through the atc0005/go-ci project.

    • New, primary workflow

      • with parallel linting, testing and building tasks
      • with three Go environments
        • "old stable"
        • "stable"
        • "unstable"
      • Makefile is not used in this workflow
      • staticcheck linting using latest stable version provided by the atc0005/go-ci containers

    • Separate Makefile-based linting and building workflow

      • intended to help ensure that local Makefile-based builds that are referenced in project README files continue to work as advertised until a better local tool can be discovered/explored further
      • use golang:latest container to allow for Makefile-based linting tooling installation testing since the atc0005/go-ci project provides containers with those tools already pre-installed
        • linting tasks use container-provided golangci-lint config file except for the Makefile-driven linting task which continues to use the repo-provided copy of the golangci-lint configuration file

    • Add Quick Validation workflow

      • run on every push, everything else on pull request updates
      • linting via golangci-lint only
      • testing
      • no builds

    • each badge also links to the associated workflow results

    • actions/checkout
      • updated from v2.3.1 to v2.3.2

  • README

    • Link badges to applicable GitHub Actions workflows results
    • Add Table of contents

  • Linting

    • Local
      • Makefile
        • install latest stable golangci-lint binary instead of using a fixed version
    • CI
      • remove repo-provided copy of golangci-lint config file at start of linting task in order to force use of Docker container-provided config file
