Module ProcessManagement 

Process Management Module

This module provides comprehensive lifecycle management for external sidecar processes within the Mountain editor ecosystem. It is responsible for:

Core Responsibilities

1. Process Spawning: Launching and configuring sidecar processes with proper environment variables, IPC channels, and communication endpoints

2. Lifecycle Management: Monitoring process health, handling automatic restarts on failure, managing graceful shutdowns, and tracking process state

3. Communication Setup: Establishing IPC connections via gRPC/Vine, performing initial handshakes, and ensuring bidirectional communication

4. Initialization Data: Constructing comprehensive initialization payloads for both the Sky frontend and Cocoon extension host

Architecture

The module is divided into two main components:

• CocoonManagement: Handles the VS Code extension host process (Cocoon) which provides compatibility with VS Code extensions

• InitializationData: Constructs and validates initialization payloads containing workspace information, extension manifests, and system configuration

Port Allocation

The module reserves specific ports for gRPC communication:

• 50051: Mountain Vine server (main process)
• 50052: Cocoon Vine server (extension host)

Feature Flags

• ExtensionHostCocoon: Enables Cocoon extension host (required for VS Code extension compatibility)

Error Handling

All operations return Result<(), CommonError> with detailed error context for graceful degradation when sidecar processes are unavailable.
