Collect or create content and exercises about working with existing/legacy code

[illicitonion]

We need to create the SDC Legacy Code module.

This will involve writing a medium-quality codebase our trainees can work in to do things like: Orient themselves, find bugs, fix bugs, add new features. We don't want to give them perfect code, or terrible code, but a realistic mix. We will need to provide specific tasks for them to do in this codebase.

We will also want to curate or create content giving techniques and advice on how to approach existing code.

We have the following draft learning objectives (which we can change if we need):

Understanding legacy code

• Explain the functionality offered by existing code
• Sketch the flow of a request through existing code

Debugging legacy code

• Identify the code responsible for a bug reported against existing code
• Identify the root cause of a bug reported against existing code

Fixing legacy code

• Identify and implement a fix for a bug in existing code

Extending legacy code

• Add a feature to existing code

We also have some experience in this from the CYF+ course "buggy app" project - talk to @illicitonion to get some lessons learned from watching people attempt this project.
