tcp

An earlier experimental TCP server and networking core written in C.

Status: discontinued, preserved for reference and learning.

Repository structure

• src/io/socket.*: socket operations.
• src/io/conn.*: connection handling.
• src/io/pool.*: experimental pooling and concurrency.
• src/server/server.*: server lifecycle.
• src/error/error.*: error handling.
• src/main.c: example server using port 8080.

Build

The existing Makefile uses Clang and ar to build a static library and demonstration executable:

make
make fclean  # remove objects and outputs

Outputs are written under bin/.

Why it was stopped

The project began as a way to explore socket lifecycles, low-level networking, and concurrency. Building out HTTP handling and performance-oriented architecture expanded the scope beyond the original learning exercise. Rather than presenting incomplete work as a supported library, the implementation remains here as a reference for individual ideas and experiments.

Related experiments: choplib/http, a separate non-blocking HTTP/1.1 server, and choplib/http-workers, a worker-based TCP prototype.

Limitations

There are no guarantees of protocol completeness, reliability, security hardening, or portability. The concurrency implementation should not be assumed correct without independent testing.
