The goal of this project is to run a fast food pizzeria.
This project, after being launched, is meant to receive orders threw a command prompt (the reception).
The reception will dispatch pizzas between several kitchens so it requires a minimum of time to prepare an order.
Each kitchen is a process and every cook is a thread of this process.
Communication between the reception and the kitchens is made (locally) thanks to unix sockets.
At the very beggining, no kitchens are open. A kitchen opens when an order has been received and no other kitchens are available (it can mean there are 0 kitchens open or that all the kitchens are busy with other orders).
If a kitchen stays open for 5 seconds without having anything to do, it closes, leaving no zombie process or thread behind.
There are several sizes for pizzas : S = 1, M = 2, L = 4, XL = 8, XXL = 16.
There are 4 types of pizzas :
- regina (baked in
1 * a * pizza_sizeseconds) made withdoe, tomato, gruyere - margarita (baked in
2 * a * pizza_sizeseconds) made withdoe, tomato, gruyere, ham, mushrooms - americana (baked in
2 * a * pizza_sizeseconds) made withdoe, tomato, gruyere, steak - fantasia (baked in
4 * a * pizza_sizeseconds) made withdoe, tomato, eggplant, goat cheese, chief love
Each kitchen has a maximum of 5 for each ingredient, which are shared between cooks.
Use the make instruction to compile the project.
Use the following commandline : ./plazza a b c
- a being the cooking time multiplier for pizzas.
- b being the number of cooks per kitchen (must be an integer since it would not be very hygienic to have parts of a body inside the kitchens 😄).
- c being the time in milliseconds needed by a kitchen to replace an ingredient.
To place an order you MUST use the following syntax : TYPE SIZE xNUMBER.
Orders can be separated by semicolons. Example : regina XXL x2 ; fantasia M x3 ; margarita S x1.
You may want to use the status command to display the status of each kitchen in activity.
