从 GitHub 操作中运行的当前工作流中获取最新成功运行的工作流的提交 hash？

Question

I'm writing a LaTeX document in a GitHub repository and I want to use git-latexdiff to compile a pdf file which shows the differences between HEAD and the commit hash of the last successful workflow run:

git latexdiff "$LAST_SUCCESSFUL_COMMIT_HASH" HEAD --no-view -o diff.pdf

So I need a way to access the commit hash of the latest successful workflow run from within the current workflow run.

I didn't find anything in the docs but maybe there is a workaround?

Answer 1

I actually solved the problem myself by writing a small GitHub Action using the GitHub Actions API :

const core = require('@actions/core');
const github = require('@actions/github');

try {
  const octokit = github.getOctokit(core.getInput('github_token'));

  octokit.actions.listWorkflowRuns({
    owner: process.env.GITHUB_REPOSITORY.split('/')[0],
    repo: process.env.GITHUB_REPOSITORY.split('/')[1],
    workflow_id: core.getInput('workflow_id'),
    status: "success",
    branch: core.getInput('branch'),
    event: "push"
  }).then( res => {
    const headCommits = res.data.workflow_runs.map(run => {return run.head_commit});

    const sortedHeadCommits = headCommits.sort( (a, b) => {
        const dateA = new Date(a.timestamp);
        const dateB = new Date(b.timestamp);
        if (dateA < dateB) return -1;
        if (dateA > dateB) return 1;
        return 0;
    });

    const lastSuccessCommitHash = sortedHeadCommits[sortedHeadCommits.length -1].id;

    core.setOutput("commit_hash", lastSuccessCommitHash)
  })
} catch (error) {
  core.setFailed(error.message);
}

This is in Powershell

$url = "https://api.github.com/repos/OWNER/REPO/actions/runs"
$token = "********"
$response = invoke-restMethod $url  -headers @{Authorization = "bearer $token"}


$response.workflow_runs | ForEach-Object {
  if($_.conclusion -eq "success"){
    $last_successful_commit = $_.head_sha
    break
  }
} 
Write-host "Last successful commit is $last_successful_commit"
