# Objective

The git panel currently runs a full `git status` for checking whether
`git` has access to the repository. This was introduced in #43693 and
currently runs on every file save which is problematic for large repos
where `git status` runs a lot of computation.

## Solution

This PR switches to a simple `git rev-parse` command which is cheap and
achieves the same goal.

## Testing

I added a unittest.
