Project 1: chirc¶

In this project, you will implement a simple Internet Relay Chat (IRC) server called chirc. This project has three goals:

To learn how to program with sockets, as well as some basic concurrent programming (including refreshing some concepts covered in CMSC 14300/14400 or 15400)
To implement a system that is (partially) compliant with an established network protocol specification.
To allow you to become comfortable with high-level networking concepts before we move on to the lower-level concepts in this course.

Please refer to the following documents to complete this project:

Make sure you’ve read our Getting Started page. That page also includes instructions on how to register for the project (and how to get your Git repo)
chirc specification: In this project, you will be implementing Assignments 1, 4, and 5 of chirc.

Initializing your Project 1 Repository¶

Make sure that you have read the Getting Started page before following the instructions below.

One-time setup instructions

Only one team member needs to run these commands. Create an empty directory and, inside that directory run the following commands. In the commands below, $REPO_URL refers to the SSH URL of your repository. To get this URL, log into GitHub and navigate to your project repository. Then, under “Quick setup — if you’ve done this kind of thing before”, make sure the “SSH” button is selected, and copy the URL that appears next to it. It should look something like this: git@github.com:uchicago-cmsc23320-aut-24/chirc-p1-jdoe-jrandom.git

git init
git remote add origin $REPO_URL
git remote add upstream https://github.com/uchicago-cs/chirc.git
git pull upstream main
git branch -M main
git push -u origin main

Cloning instructions

Once the repository has been set up, you can clone the repository in other locations as follows:

git clone $REPO_URL
git remote add upstream https://github.com/uchicago-cs/chirc.git

Submission¶

Before submitting, make sure you’ve added, committed, and pushed all your code to GitHub. You will submit your code through Gradescope, which you can access through our Canvas site.

When submitting through Gradescope, you will be asked to select a repository to submit. Make sure that you select the correct repository and branch. Please note that you can submit as many times as you want before the deadline.

Please note that you must make a single submission per pair of students (do not make two submissions, one per student). When making your submission, you will be allowed to add “team members” to your submission. Make sure you add your project partner in your submission.

In this project, Gradescope will only fetch the following files from your repository:

All .c and .h files inside the src/ directory (including any subdirectories you may have added in that directory)
The CMakeLists.txt file in the root of your repository
The DOCUMENTATION.md file in the root of your repository

Once you submit your files, an “autograder” will run. This autograder should produce the same test results as when you run the code yourself; if it doesn’t, please let us know so we can look into it.
