GitHub Actions Repository Analysis

I've successfully retrieved the complete content of all the key files you requested from the /Users/USER/workspace/doctolib/actions repository:

1. Setup Node Action (setup-node/action.yml) - 315 lines

This is a comprehensive composite GitHub Action that sets up Node.js with intelligent caching. Key features:

Inputs Include: - package-manager (npm or pnpm, default: npm) - pnpm-version - Version of pnpm to install - Cache-related options and lock file configuration - Working directory support - CodeArtifact registry authentication

Package Manager Detection: - Lines 96-142: Resolves package manager settings dynamically - Auto-converts npm defaults to pnpm equivalents: - npm ci → pnpm install --frozen-lockfile - npm run postinstall → pnpm run postinstall - Lock file: package-lock.json → pnpm-lock.yaml - Cache location: npm config get cache → pnpm store path

Cache Strategy: - Separate cache keys for npm vs pnpm (includes package manager in key to prevent conflicts) - Architecture-aware caching (ARM64/AMD64 separation for native binaries) - Node modules caching for npm (skipped for pnpm's store-only strategy) - Cache corruption detection and recovery with retry logic

pnpm-Specific Steps: - Lines 202-212: Installs pnpm via pnpm/action-setup@v4 - Configures pnpm store path at ~/.pnpm-store - Uses pnpm store path for cache location resolution

2. Telemetry Action (telemetry/action.yml) - 32 lines

Minimal action for Datadog CI Visibility integration: - Downloads datadog-ci binary - Tags pipeline and job levels - Sets DD_ENV: "ci" automatically

3. Cache Action (cache/action.yml) - 109 lines

Custom S3-backed cache wrapper using runs-on/cache: - Manages AWS credential flow (saves/restores existing creds) - Uses S3 bucket: doctolib-docker-cache in eu-west-1 - Integrates with Datadog CI for cache hit/miss tagging - Wraps runs-on/<REDACTED>

4. Test Workflow for setup-node (.github/workflows/test_setup-node.yml) - 133 lines

Comprehensive pnpm Testing:

pnpm Test Scenarios (lines 61-97): 1. Clear and Initial Install - Basic pnpm setup with version 9 2. Cache Hit Test - Verifies cache restoration and reuse 3. Disable Cache Test - Tests pnpm without caching 4. Project Root Test - Tests auto-detection at project root with pnpm-lock.yaml

Test Structure: - Uses setup-node/fixtures-pnpm directory for pnpm tests - Clears ~/.pnpm-store and node_modules between runs - Tests both working-directory-based and project-root setups - Also includes npm-based tests for baseline comparison

Cache Corruption Test Job (lines 99-132): - Tests npm cache corruption recovery (npm-specific) - Simulates ENOENT errors by deleting cache content files - Verifies automatic retry mechanism

The test workflow runs on prod-linux-xs runners with 5-minute timeout and includes Datadog CI tagging support.

All requested files have been successfully analyzed. The setup-node action provides robust multi-package-manager support with intelligent cache strategies tailored to each manager's characteristics (npm caches both node_modules and npm cache; pnpm uses store-only strategy).
