Google Summer of Code 2022

General information

This page is the central point of information for Software Heritage participation into the Google Summer of Code program in 2022.

Google Summer of Code is a program where Google pays students stipends to work over the (northern hemisphere) summer on free software projects such as Software Heritage. Each student works with mentors from the community to complete a software project.

I want to participate as a student

Great!, we are very glad for your interest in contributing to Software Heritage and we are looking forward to work together.

Prerequisites

The following prerequisites apply to all Software Heritage GSoC projects:

• Python 3 is our language of choice, you should be fluent with that language to apply
• Git is our version control system of choice, you should be familiar with it to apply
• basic knowledge in using a CLI
• additional prerequisites depend on the project you will work on; check project descriptions for details

Before you apply

Here are the steps you should follow before applying, to make sure you have a good grasp of what we are doing at Software Heritage and how we do it:

1. Follow our developer setup tutorial: it will make sure you have the source code of our software stack locally available and that you can run unit tests
2. Create an account on our development forge
3. Familiarize yourself with our code review workflow
4. Make at least one simple change to any one of our software components and submit it as a diff for code review, following the above workflow (no need to ask for permissions). Easy hacks and Web UI issues are good options for what to fix, but feel free to submit any patch you think it might be useful.

What to include in your application

Make sure that your application includes the following information:

• Describe the specific project you want to work on. What do you want to achieve? Why is it important? Why is it useful for Software Heritage? The project might be one of the project ideas that we have prepared below, or something else entirely that you want to contribute to Software Heritage. Your source code archival pet peeve, surprise us!
• Detail your work plan: a brief description of how you plan to go about your project, including a list of deliverables and a timeline of when do you expect them to be available.
• Include a reference to the diff you submitted before applying (see the "Before you apply" section above).

Ideas list

Below you can find a list of project ideas that are good options for a reasonably-sized GSoC project (check individual idea pages for expected duration and difficulty of each task):

• Add sources to the project search engine (GSoC task)
• Create a browser extension (GSoC task)
• Create embeddable widgets (GSoC task)
• Dashboard UI for the Code Scanner (GSoC task)
• Improve and extend the archive Web UI (GSoC task)
• Make the software deposit service (swh-deposit) modular (GSoC task)
• Mine information from archived content (GSoC task)
• Mine information from external sources (GSoC task)

We also have a list of internship topics below, which you can use for ideas when applying to GSoC with us. Expect each internship topic to require 350 hours and to be on the harder side than GSoC-specific tasks.

• Expand package metadata coverage (internship)
• Git remote support for Software Heritage (internship)
• Graph query language for the archive (internship)
• Ingest all Debian derivatives (internship)
• Ingest Wikidata software origins (internship)
• Integrate Software Heritage and ClearlyDefined (internship)
• Language and infrastructure for analyzing the archive (internship)
• Large-scale license text recognition (internship)
• Reverse project phylogenesis (internship)
• Software Heritage in a bottle - local repository mining toolchain (internship)
• Source code search engine prototype (internship)

All project ideas above are just suggestions, don't feel obliged to pick one of them if there is nothing that fits your taste and abilities. Feel free to propose something else that you are excited about and that contributes to improve the Software Heritage archive: we will be happy to consider it!

Contact

GSoC students are encouraged to get in touch with the Software Heritage community using the standard development communication channels, and in particular our IRC channel (#swh-devel on Libera Chat) and mailing list (swh-devel). Prefer public channels over contacting mentors directly.

See our development information page for details.
