An example, not entirely stable, web server

Prerequisites

• Linux or MacOS
• Optionally: the C++ IDE juCi++
  • If you do not install juCi++, you will need to install additional dependencies such as g++, cmake and make

Installing dependencies

Debian based distributions

sudo apt-get install libboost-thread-dev libboost-regex-dev

Arch Linux based distributions

sudo pacman -S boost

MacOS

brew install boost

Download

git clone https://gitlab.stud.iie.ntnu.no/eidheim/buggy-web-server

Compile and run

Alternative 1

In a terminal:

juci buggy-web-server

In juCi++, choose Compile and Run in the Project menu.

Alternative 2

In a terminal:

cd buggy-web-server
mkdir build
cd build
cmake ..
make
./web_server  # Press control-c to stop the server

See web page

Alternative 1

Open http://localhost:8080 in a web browser

Alternative 2

In a terminal:

telnet localhost 8080
GET / HTTP/1.1        # Press enter twice here

Debugging

First, stop the web server (if it is running). In juCi++, choose Kill Last Process in the Project menu.

In a terminal:

cd build
mkdir debug
cd debug
cmake -DCMAKE_BUILD_TYPE=Debug ../..
make
gdb ./web_server                     # In MacOS, instead use: lldb ./web_server
run
