build workflow (ssut/payload-dumper-go)

The build workflow from ssut/payload-dumper-go, explained and optimized by Latchkey.

What it does

This is the build workflow from the ssut/payload-dumper-go repository, a real project running GitHub Actions. It is shown here with attribution under its Apache-2.0 license.

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

The workflow

name: build

on: [push, pull_request]

jobs:
  build:
    runs-on: ubuntu-latest

    steps:
      - name: Install dependencies
        run: |
          sudo apt -y update
          sudo apt -y install git golang liblzma-dev

      - uses: actions/checkout@v4

      - name: Build
        run: go build .

The same workflow, on Latchkey

Removes redundant runs and caps runaway jobs. Added and changed lines are highlighted.

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• Cancel superseded runs when a branch or PR gets a newer push.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 per trigger. On Latchkey the same minutes cost up to 58% less than GitHub-hosted, with zero queue time.
