Method status

atomic-repository/src/repository/status.rs:24–448

Compute the status of the working copy. Optimized for repositories with tens of thousands of files: 1. **Single TREE pass** — builds tracked_paths + inode_map together 2. **FILE_INDEX fast path** — stat-only check for unchanged files 3. **Clean files skipped** — only Modified/Added/Deleted/Untracked allocated 4. **Deferred walkdir** — filesystem walk only when untracked files requested # Perfor

        // Always build the explicit change filter.  The TREE table is
        // global — it contains entries from ALL views, including child
        // views.  Without filtering, files recorded on child views leak
        // into the parent's status as false "Deleted" entries.
        //
        // The previous "universal" fast-path (skip filter for
        // is_shared() && parent.is_none()) was unsound: the dev view is
        // shared with no parent, but child/sibling views may have unique
        // changes.  Skipping the filter caused TREE entries created by
        // those changes to surface as phantom `Deleted` files in dev's
        // status.
        //
        // The filter computation is O(C) where C is changes on the view —
        // a single B-tree scan, fast even on large repos.
        //
        // None means "no current view" (a misconfigured repo); preserve
        // the legacy "show everything" behavior in that case rather than
        // producing an empty status.
