sv

A basic web server written in C with support for TLS

Dependencies

This project depends on OpenSSL (-lssl and -lcrypto), libmagic and GCC. If you are using a moderately recent linux distribution these should be already present.

How to build

make

How to use

A default configuration is present in config.conf. To invoke run ./sv config.conf this will default to serving a test website on port 9092

Particularities

• This server is single threaded I might make it multithreaded at some point I tried to keep the number of "globals" to a minimum so it should be relatively straight forwards.

• This project depends on GCC In order to try and cut down on possible memory bugs, this project is build with GCC's -fanalyzer.

• This server supports TLS

• This server currently only supports one connection per thread, this results in the server being pretty slow.

What do do next

• Multi-threading

• More than 1 connection per thread, io_uring or libuv both look interesting, probably will go with libuv.

• Make it so that the tls detection code does not break the handshake from the point of view of the ssl lib, ungetc perhaps.

• Lots of TODOs in the code.

• More tests
