SimpleChat Phase 2 – SEG2105 Assignment 2

📌 Overview

This project extends the Phase 1 SimpleChat application using the OCSF framework. It introduces enhanced client-server functionality, command handling, and user identification to support a more interactive and robust messaging system.

🛠 Features Implemented

✅ Client-Side Enhancements

• Graceful shutdown detection when server disconnects
• Support for custom port and host via command-line arguments
• Command interface using # prefix:
  • #quit, #logoff, #login
  • #sethost, #setport, #gethost, #getport
• Mandatory login ID passed as first argument
• Automatic #login <loginid> sent to server on connect

✅ Server-Side Enhancements

• Console interface via ServerConsole class
• Server commands:
  • #quit, #stop, #close, #start
  • #setport <port>, #getport
• Displays connection/disconnection messages for clients
• Handles #login <loginid> from clients
  • Stores login ID
  • Prefixes messages with login ID
  • Rejects duplicate or late login attempts

🧪 Test Cases

All 13 test cases from the assignment document were executed and passed:
