Http-Server

C implementation of http Server that can host any http websites. Server can be run in following ways,

1. Serially : Single thread of execution will handle every request one after another.
2. Using processes : For new request new process is created.
3. Using Threads : For new request new thread is created.
4. Using ThreadPool : Limited number of threads handles the job one after another(most efficient).

Files:

bounded_buffer.c/h: Implementation of circular queue.

csuc_http: Implementation of head file that has structures of http header packages.

log.c/h: Functions that manages logs.

Server.c: Main implementation of server code.

Stimer.c/Stimer.h: All required functions to manage time.

supporting_functions.c: Small functions those are used in server.c

Running

Compile using MakeFile and run with the options available.

make
http_server -d sample_site

Options

-d :

Set directory location of website to be hosted.

http_serve -d sample_site

-p :

Set port number of server.

http_serve -d sample_site -p 9000

-f :

Run server using multiple processes. For every new request process will get created.

http_serve -f -d sample_site -p 9000

-t :

Run server using threads. For every new request thread will get created.

http_serve -t -d sample_site -p 9000

-w :

Run server with limited numbers of worked threads.

http_serve -w 10 -d sample_site -p 9000

-q :

Limit the queue size for thread pool strategy. Only use this option with -w.

http_serve -w 10 -q 10 -d sample_site -p 9000

Serial Operation :

If no f,t,w options are provided, server will run in serial mode.

http_serve -w 10 -d sample_site -p 9000

-v:

Set log level to ERROR,WARNING,INFO or DEBUG.

http_serve -w 10 -d sample_site -p 9000 -v ERROR
http_serve -w 10 -d sample_site -p 9000 -v WARNING
http_serve -w 10 -d sample_site -p 9000 -v INFO
http_serve -w 10 -d sample_site -p 9000 -v DEBUG

ignals Handled:

SIGINT|SIGTERM :

Use ctrl + c to shutdown server or use kill.

SIGUSR2:

Change the current log level.

    If process id for my server is 34567
    kill -SIGUSR2 34567

    Current log level INFO

SIGUSR1:

Display server statistics.

    If process id for my server is 34567
    kill -SIGUSR1 34567
