" In this assignment you will write a C++ program that simulates a naïve hierarchical computer file system. To communicate with the file system, you will implement a command-line/terminal that enables the user to create/delete files/folders, print the contents of a directory etc. The file system consists of a root directory (“/”) and optionally other files and directories underneath. The program has a global variable called verbose to control its output. See the verbose command for details. Your program will be executed in the following way: “./bin/fs”. Your program must not receive any external arguments "
" In the following assignment you are required to implement an Actor ThreadPool, and to use it to build a University Management System. In Actor thread pool, each actor has a queue of actions. One can submit new actions for actors and the pool makes sure that each actor will run its actions in the order they were received, while not blocking other threads. The threads in the pool are assigned dynamically to the actors. As an SPL181 team you will implement an Actor Thread Pool."
" In this assignment you will implement an online movie rental service (R.I.P. Blockbuster) server and client. The communication between the server and the client(s) will be performed using a text based communication protocol, which will support renting, listing and returning of movies. Please read the entire document before starting. The implementation of the server will be based on the Thread-Per-Client (TPC) and Reactor servers taught in class. The servers, as seen in class, do not support bi-directional message passing. Any time the server receives a message from a client it can reply back to that specific client itself, but what if we want to send messages between clients, or broadcast an announcment to all clients? The first part of the assignment will be to replace some of the current interfaces with new interfaces that will allow such a case. Note that this part changes the servers pattern and must not know the specific protocol it is running. The current server pattern also works that way (Generics and interfaces). Once the server implementation has been extended you will have to implement an example protocol. We will implement the movie rental service over the User service textbased protocol. The User Service Text-based protocol is the base protocol which will define the message structure and base command. Given an implementation of the protocol we can implement many user service applications. The service you will build is a movie rental service. Since the service requires data to be saved about each user and available movies for rental, we will implement a simple JSON text database which will be read when the server starts and updated each time a change is made. Note that these kinds of services that use passwords and/or money exchange require additional encryption protocols to pass sensitive data. In our assignment we will ignore security and focus on network programming. You will also implement a simple terminal-like client in C++. To simplify matters, commands will be written by keyboard and sent “as is” to the server "
