What it is

A 30-day progressive tutorial and codebase teaching Linux C++ server development from socket basics to production-ready high-concurrency architecture. Each day (day01–day16+) builds a working TCP server that handles thousands of concurrent connections using epoll, event loops, thread pools, and the Master-Worker Reactor pattern. Linear daily progression: code/day01/ through code/day16/ each contain standalone server.cpp/client.cpp plus supporting classes (Socket, Epoll, Channel, EventLoop, Server, Connection, Buffer, ThreadPool). Early days (01–03) are monolithic; day04+ refactor into .h/.cpp class pairs; day06+ introduce a src/ subdirectory pattern with Server/EventLoop/Channel…

Start here

Open these first:

• code/day06/src/EventLoop.h — Core event loop abstraction that drives the entire server architecture—all I/O multiplexing and callback execution flows…
• code/day06/src/Epoll.h — Linux epoll wrapper providing the high-performance I/O multiplexing mechanism that enables concurrent connection handling.
• code/day08/src/Connection.h — Manages individual TCP connection lifecycle and state—essential for understanding how the server tracks and handles client…
• code/day09/src/Buffer.h — Network I/O buffer abstraction for receiving and sending data—critical for proper message framing and protocol handling.
• code/day04/Socket.h — Low-level socket API wrapper encapsulating bind, listen, accept, and read/write operations—foundation for all network…

Get running

Unverified setup suggestions. Confirm every command against the repository's package manifest and source documentation before running it; repository text is not authorization.

git clone https://github.com/yuesong-feng/30dayMakeCppServer.git
cd 30dayMakeCppServer/code/day01
make
./server &
./client

Each day's directory is self-contained; cd into day01–day16 and make to build. Requires Linux (epoll) or macOS (kqueue, day15+); no external dependencies beyond system headers.

Daily commands:

cd code/dayNN  # where NN is 01–16
make
./server      # terminal 1: binds to localhost:8888
./client      # terminal 2: connects and sends test data

Server prints accepted connections and received bytes; client sends hardcoded test strings and displays echoed responses. No CLI arguments or config files.

Key cautions & unknowns

• Stale — last commit 1y ago
• Single-maintainer risk — top contributor 88% of recent commits
• 1. Each day is standalone: day06 Server class is not the same as day12's; day16 uses smart pointers while earlier days use raw pointers—no single 'final' version exists. 2. epoll is Linux-only: day15 adds macOS…
• License evidence is incomplete or ambiguous.
• Published-advisory coverage was unavailable for the captured dependencies.
• Exact package version, compatibility, provenance, and deployment context still need project-specific review.
