Walkthrough

A new GitHub Actions workflow was introduced that orchestrates building and deploying the playground application to a CDN via Huawei Cloud Object Storage. The workflow validates credentials, builds the playground with versioned metadata including Shanghai timestamps, and uploads artifacts to OBS with versioned and conditional latest-release paths.

Summary

GitHub Actions CDN Deployment Workflow \.github/workflows/deploy-playground-to-cdn\.yml

Introduces new deployment workflow with three jobs: check-secrets validates Huawei Cloud credentials, build clones repo, configures pnpm/Node.js, caches dependencies, and generates version metadata with Shanghai timestamp appended to playground package.json version. Exports CDN_BASE, CDN_BASE_LATEST, OBS_PATH, and OBS_PATH_LATEST environment variables. deploy-cdn job retrieves build artifact, installs obsutil, uploads dist to versioned OBS path, and conditionally updates references in HTML/JS/CSS files for latest release deployments.

Poem

🐰 With whiskers twitching, I build and deploy,
Shanghai timestamps bring rabbity joy,
To Huawei's clouds, the playground springs,
Versioned paths and CDN wings! 🚀

In @.github/workflows/deploy-playground-to-cdn.yml:
- Around line 149-155: Replace the current unpinned download in the "Install
obsutil" step by pinning to a specific obsutil release (avoid /current/),
download both the tarball and the corresponding official SHA256 file, compute
the SHA256 of the downloaded tarball and compare it to the official value, and
abort the workflow with a clear error if the checksum does not match; update the
step that currently runs curl/tar/chmod/mv so it fetches the versioned URL and
checksum, performs the sha256 verification before extracting, and only proceeds
to chmod and sudo mv obsutil when the hash check succeeds.
