Would a git hook block you from committing it locally, or would it just run on the server side?
I’m not sure how our one at work is implemented, but we can actually commit @nocommit files in our local repo, and push them into the code review system. We just can’t merge any changes that contain it.
It’s used for common workflows like creating new database entities. During development, the ORM system creates a dev database on a test DB cluster and automatically points the code to it with a @nocommit comment above it. When the code is approved, the new schema is pushed to prod and the code is updated to point to the real DB.
Also, the codebase is way too large for something like ripgrep to search the whole codebase in a reasonable time, which is why it only searches the commit diffs themselves.
