Allow for Delta Runs

[JeroenKnoops]

Problem

We're making a great use of this template.
We're very happy, but in a large organization, this solution does not scale.

When adding 1 person to a group, all repositories are being checked and the run can take up to 3 hours.

Solution

Instead of running everything for all repositories and users, we can also only run the scripts on the files which are changed in the PR.

How to determine which files are necessary

We've created a CLI tool to determine which files need to be included for certain changes.
When a repos file has been changed, we're looking in the groups folder for files which are used for those repos. Same for changes in a groups file, we're looking into the repos folder for relevant files until we found all relevant files.

Process

We're removing all files in repos and groups and only add the found files and process as normal.

Every night we run a complete check.
We can trigger a complete run of x hours manually, if needed.

Used tools

• Action to see which files are changed in a PR: tj-actions/changed-files@v35
• CLI tool (written in Rust) to find the files
• Slack Notificator when complete files are removed, manual actions are required
• Unmodified Outside-collaborators scripts

Share

Do you want me to share this code in a separate repository so people can use these delta runs as well?
