Method open_readonly

atomic-repository/src/repository/mod.rs:399–427

Open an existing repository in read-only mode. This method opens the repository without acquiring a write lock on the database, allowing concurrent read access from multiple processes. It's suitable for read-only operations like `status`, `diff`, `log`, and `change`. Use this method when you only need to query the repository state and don't need to make any modifications. This is especially usef

            return Self::open_sandbox(working_root, canonical, &view);
        }
        let root = Self::find_root(path.as_ref())?;
        let dot_dir = root.join(DOT_DIR);
