"Duplicate originals" appears under the trash in the collections sidebar while the catalog holds any, and Settings says how many there are beside the other whole-library passes. Both open one page: every group with its picture and paths, the copy that stays (tap another path to change it), a per-group Include box, what the survivor will gain and any flag, label or face conflict, and why a group was skipped. The summary is the dry run -- "N groups, M files to trash, K skipped" -- and nothing moves until "Check" has read the copies and "Move M copies to trash" is pressed. Both run on workers with progress on the page, in the activity register and, for the move, on the library status line; Stop ends a job between groups. When it ends the grid, the sidebar and the trash are refreshed and the survivors' judgements are written to their sidecars and XMP the way a rating keystroke writes them. The page is paginated at 30 groups, so a redraw decodes 30 thumbnails and previews 30 merges whatever the size of the library. Back and Escape leave it like its own Back button.

//! TRACES: FR-CAT-4 | FR-NC-3 | NFR-P9
|
|
//! Drives the library grid from scan and thumbnail workers.
|
|
//!
|
|
//! Owns the bridge between three background activities and one single-threaded
|
|
//! event loop:
|
|
//!
|
|
//! - a **scan** worker walking the remote tree into the catalog
|
|
//! - a **thumbnail** worker range-fetching previews for visible cells
|
|
//! - the **grid model** Slint renders
|
|
//!
|
|
//! Nothing here blocks. Workers post through mpsc channels drained by Slint
|
|
//! timers, which is the same shape [`crate::launch_ui`] uses for login.
|
|
//!
|
|
//! # Why thumbnails are fetched, not derived from the scan
|
|
//!
|
|
//! A scan yields paths and sizes, nothing visual. Each thumbnail costs its own
|
|
//! range request, so they are fetched **only for cells the grid actually
|
|
//! wants** — never for the whole library up front. On the reference library
|
|
//! that is the difference between a few MB and ~370 GB (ARCH §6.7).
|
|
//!
|
|
//! Split into one module per area of behaviour (docs/dev/code-health.md CH-1):
|
|
//! `controller` holds the running state every other module reads and writes
|
|
//! through `pub(super)` fields; `open` is the launch-to-scan cycle and the
|
|
//! worker that checks the catalog file before either touches it; `offline`
|
|
//! is what of a collection is on this device and the prompt that offers to
|
|
//! change it; `window` fills the grid model from the catalog and drains the
|
|
//! thumbnail fetch; `sync` is the background passes that reach beyond the
|
|
//! loaded window — the metadata sweep, the whole-library thumbnail pass, and
|
|
//! the exchange with the server; `ratings_keywords` applies a judgement or a
|
|
//! keyword to a selection and queues the sidecar and XMP writes behind it;
|
|
//! `timeline` is the capture-time sidebar and the photographer's place,
|
|
//! which move together closely enough to live in one file; `grid` wires the
|
|
//! grid's own callbacks — the keyboard cursor, cell-size zoom, the routes
|
|
//! into and out of develop; `filter_bar` wires the rating, people, date and
|
|
//! offline-scope filters. `mod.rs` re-exports what the rest of the crate
|
|
//! calls by `library_ui::` path, so nothing outside this module needs to
|
|
//! change.
