⚖️ Safety Assessment: ✅ Safe

🔍 Release Content Analysis

This PR updates the ghcr.io/codize-dev/piston Docker image digest from c8a33a5 to 50dcb6f. The changes are triggered by an upstream merge (commit 04c2371) that updated base Docker images.

Changes in the New Image (built 2026-02-24):

1. Base Image Updates (from PR Update buildpack-deps:bookworm Docker digest to a6934e0 #39):

   • buildpack-deps:bookworm digest: c35adcb → a6934e0
   • node:20.19.6-bookworm-slim digest: a270640 → b342de0

2. Package Enhancements:

   • Go 1.25.5: Added pre-downloaded golang.org/x/text module support for offline builds
   • Rust 1.93.1: New package added to the language runtime collection

3. Image Characteristics:

   • Size reduction: 654.2 MB → 653.2 MB (~1 MB smaller)
   • Node.js version: 20.19.6 (unchanged)
   • No changes to environment variables or exposed ports
   • Configuration digest changed: f504e46... → 12631d1...

Type of Update:

• Routine base image security and maintenance updates (Debian Bookworm base layer updates)
• No breaking API changes
• No changes to Piston API functionality or configuration interface

🎯 Impact Scope Investigation

Usage Analysis:

The Docker image is referenced in:

1. docker-compose.yaml (production): Uses pinned digest (this PR's target)
2. docker-compose.dev.yaml (development): Uses build: api (not affected)
3. GitHub Actions workflows (.github/workflows/*.yaml): References for CI/CD automation

Impact Assessment:

• API Compatibility: No changes to API endpoints, environment variables, or runtime behavior
• Configuration: No changes required to docker-compose.yaml volume mounts, ports, or environment variables
• Dependencies: Base image updates only affect the container's internal dependencies (system libraries)
• Backwards Compatibility: Fully maintained - the API server interface remains identical
• Security: Base image updates typically include security patches from Debian Bookworm upstream

Dependency Chain:

• The image uses pinned digest notation (@sha256:...) ensuring reproducible deployments
• No changes to the API surface exposed on port 2000
• Language runtime packages in /piston/packages volume remain compatible

💡 Recommended Actions

Immediate Actions:

1. ✅ Safe to merge - This is a routine base image update with no breaking changes
2. Test the updated image in a staging environment (optional but recommended):

   docker pull ghcr.io/codize-dev/piston@sha256:50dcb6f013b1f5de8b544974ec6ff220a9e1c522151da1a2a950b8735fceecc1
   docker-compose up -d

3. Verify API functionality after deployment:

   curl http://localhost:2000/api/v2/runtimes

Post-Merge:

• Monitor application logs for any unexpected behavior (though none is anticipated)
• No code changes required in the application
• No configuration updates needed

Why This is Safe:

• Base image updates only affect internal system libraries (security patches, bug fixes)
• The Piston API image maintains the same Node.js version (20.19.6)
• Docker digest pinning ensures you get exactly this tested version
• The upstream PR Update buildpack-deps:bookworm Docker digest to a6934e0 #39 was successfully built and tested via GitHub Actions (workflow run: 22331492268)
• Image size actually decreased slightly, indicating cleanup or optimization
