action #138029
Updated by okurz 6 months ago
## Motivation
Whilst a `wheels.yaml` is in place a request to GitHub is made for each reference to a GitHub-hosted repo in that file every time a job is prepared. This can amount to several hundreds of attempts daily even with a single repo. This is why we should look into caching wheel repositories, i.e. tiny git repositories, which are commonly stored on github. So I suggest we research a bit what are current best practices how to handle that. Maybe there are generic solutions and we don't want to reinvent the wheel.
## Acceptance criteria
* **AC1**: When there are no changes to a wheel repository we know how openQA tests on workers could access the content of wheels from a location within the openQA infrastructure without needing to reclone from github
* **AC2:** When there are changes to a wheel repository we know how openQA tests would be able to access to most recent code version from wheel repos
## Suggestions
* Read #60272
* Conduct a web research how to "cache github repositories"
* Look into "git worktrees" for repositories and branches, see #60272
* Look into the existing caching mechanisms used for needles and test distributions
* Optional: Build a prototype
