agent_instance: tripathi456_gvisor-based-python-repl_issue_15_326d48a9 Tries to fix: #15

🚀 Implemented ForeverVM Minimal: A Python REPL persistence system

• Added: Complete implementation using pickle-based serialization for session persistence
• Added: Worker pool management, stdout capture, and expression/statement evaluation support
• Added: HTTP API with Flask for session creation and code execution

This PR delivers a minimal implementation of ForeverVM that enables persistent Python REPL sessions by serializing the environment state, with support for idle session checkpointing and automatic restoration when needed. Ready for review!

use uv to initialise the project inside the forevervm_minimal folder.

[tripathi456]

you have to take a cue from the command

docker run --runtime=runsc --rm -it \
  -v "$(pwd)/server.py:/server.py" \
  -p 8000:8000 \
  python:3.9.21-alpine3.21 \
  python /server.py

So that the main.py you wrote can be run inside a docker (inside gvisor)

🐳 Added Docker with gVisor Support for ForeverVM

I've created the necessary infrastructure to run ForeverVM in a Docker container with gVisor runtime for improved isolation and security:

• Created: Dockerfile based on Python 3.9.21 Alpine for a lightweight container setup
• Added: Standalone server.py script that can run directly in the container
• Added: Multiple deployment scripts (docker-run.sh, docker-run-simple.sh, run-forevervm.sh) for flexibility

The implementation follows the requested pattern of mounting the server script and snapshot directory into the container, ensuring ForeverVM can run safely within the gVisor sandbox.

🐳 ForeverVM in gVisor Docker Implemented

• Added: Docker/gVisor integration for ForeverVM minimal implementation with standalone server.py that bundles all components into a single file
• Added: Various runtime scripts including run-forevervm.sh for gVisor container deployment and test-forevervm.py for API testing
• Added: Combined server supporting both HTTP and TCP protocols with proper isolation via gVisor runtime

The implementation follows the requested pattern for running a Python REPL in a secure gVisor container and persisting sessions using ForeverVM's custom serialization. Ready for review!
