nirvananimbusa / threaded-server

A stupid simple server with threading

threaded-server

Servers static files and prevents path traversal attacks. Will probably crash if you try anything fancy.

However, it handles requests at about 10 msec/response, which is comparable to Nginx. Try ab -n 1000 -c 100 localhost:8080/ for a comparison.

Usage

$ ./main -h
usage: ./main [<port>] [<host>]

Compiling

Dependencies

• make (or gmake on Mac/BSD)
• a C compiler. clang is the default, change CC=gcc in the makefile if you don't want to install it.
• libmagic (brew install libmagic on Mac, should be preinstalled on Linux/BSD)

Testing

Dependencies

• sed/grep
• curl
• ab (apt install apache2-utils on debian/ubuntu)
• clang-tidy
• cppcheck
• bash and bats

Running Tests

make test

Optional

valgrind --leak-check=full build/main 8080

Run a few queries and see if there's any memory leaks.

But Why?

I'm taking networking and operating systems courses where we don't write any code. I thought it would be nice to get hands-on in system internals.

TODO

• Figure out why -fsanitize=thread thinks my interrupt handler isn't safe
• Check what happens if we run into the thread limit (currently, we spawn a thread for every request no matter how many threads we already have)
• Figure out why sleep(10) in handle_request adds a response time of 18 seconds
• Logging (?)
• Dynamic pages (??)
• HTTP/2.0 (???)
