PortChat

The problem

Handling several conversations at once requires the server to manage concurrent connections without blocking message delivery or letting threads interfere with shared state.

What I built

PortChat implements a server-client architecture for text communication across a network. A Python server listens on a port and handles clients in separate threads, allowing multiple people to connect and exchange messages. Commands cover connecting, sending messages, and exiting.

• Use Python sockets to connect clients to a listening server.
• Run each incoming client connection in a separate thread.
• Use locks to protect shared resources and address race conditions.
• Provide commands for connecting, sending messages, and disconnecting.

The result

A Python network chat application built with sockets and threads.
