Go workflow (kashav/fsql)

The Go workflow from kashav/fsql, explained and optimized by Latchkey.

What it does

This is the Go workflow from the kashav/fsql repository, a real project running GitHub Actions. It is shown here with attribution under its MIT license.

Below, Latchkey shows a faster, safer version produced by its optimization engine.

The workflow

name: Go

on:
  push:
    branches: [ master ]
  pull_request:
    branches: [ master ]

jobs:
  build:
    runs-on: ubuntu-latest
    strategy:
      matrix:
        go-version: [ '1.19', '1.20', '1.21' ]

    steps:
    - uses: actions/checkout@v3

    - name: Set up Go ${{ matrix.go-version }}
      uses: actions/setup-go@v3
      with:
        go-version: ${{ matrix.go-version }}

    - name: Install dependencies
      run: go get .

    - name: Build
      run: make

    - name: Test
      run: make test

The same workflow, on Latchkey

What changed

• Run on Latchkey managed runners with one line (runs-on), which apply the fixes below automatically and self-heal transient failures. This example uses latchkey-small; pick the runner size that fits the job.
• Cancel superseded runs when a branch or PR gets a newer push.
• Add a job timeout so a hung step cannot burn hours of runner time.

This workflow runs 1 job (3 with the matrix expanded) per trigger. On Latchkey the same minutes cost up to 58% less than GitHub-hosted, with zero queue time.
