A 4:1 composite drawn in one square cell is a strip a few pixels high.
A photograph about twice as wide as it is tall (1.9 and up) now spans
two columns, three from 2.9, with a thumbnail class of its own whose
long edge is sized for that width; on the tablet, or where the columns
are too few to put it beside anything, it takes the whole row.
Rows are computed in one place, library_ui::layout. The grid is a
lattice of slots: each cell is drawn at the slot Rust gives it, and a
wide cell that would not fit in what is left of a row starts the next
one, leaving the gap empty so the grid still reads in capture order.
The scrollbar spans the slots, a scroll reports a slot that the layout
turns back into an ordinal, and scrubs, restores and the cursor go
through the same conversion. Up and down step by rows through the
layout rather than by a row's worth of ordinals; left and right, a
shift-click's run, burst folding and the timeline are ordinal-based
and unchanged.
The window's own read carries each photograph's w and h, so the cells
know their shape with no query per cell. Where the wide ones sit in
the whole list is one query, run when what the grid lists changes or
when a window finds the layout out of date, and a library with no
panorama answers it from a partial index created on first use
(images_wide), not a schema bump. The merge makes the wide thumbnail
for a wide composite along with the others.
rustfmt over the files the albums work touched, and the album merge's
incoming row as a named struct rather than an eight-field tuple, which
clippy's type_complexity refused.
Export took a path typed into the settings page, or a folder inside the
library on the server. The first is how exports end up somewhere nobody
looks; the second put JPEGs into the tree a scan catalogues, where they
came back as photographs beside the RAWs they were made from.
The destination is now an album (FR-EXP-10), chosen by name in the
export sheet. Albums are listed under the collections in the sidebar;
"+" there, or "New album…" in the sheet, opens a sheet for its name and
its folder — on this device through the platform's dialogue, or on the
server through the browser with "New folder". A server folder inside
the library is refused, and the sheet says why. Selecting an album
narrows the grid to the photographs behind its files: library::Scope
is Collection or Album, and scope_clause is the one place the two are
spelled, which also retires the two copies of the collection predicate
total_images_scoped and read_cells_scoped had inlined.
A batch resolves the album when it starts, and refuses in words when
none is chosen, it has gone, or its folder is local to another device.
Each item reports the image it came from, and the files written are
recorded against the album in one transaction when the batch ends.
A server album lives outside the library, so its queued uploads are
relative to the account root. That is a third line in the outbox's
.dest record rather than a leading slash, because a record written
before albums may carry a stray slash and must keep the meaning it was
written with.
An export folder set before albums becomes an album called "Exports"
on first open, so upgrading does not lose where exports were going.
The old destination fields stay in ExportSettings so older settings
files still read.
library.rs was 7,729 lines wiring together everything "open a remote
library" touches: scanning, pulling other devices' judgements out of
sidecars found along the way, writing local edits back out to the
sidecar outbox, pushing/reloading XMP by hand, fetching and prefetching
thumbnails and originals, generating thumbnails locally, the metadata
and thumbnail background sweeps, on-disk paths for the catalog and
model files, and reading the grid's cells, spans and rating filter.
Same motivation as the develop.rs split (docs/dev/code-health.md CH-1):
a pure, no-behaviour-change move into one file per area, each under
about 1,500 lines.
Tracing actual call sites rather than trusting the file's physical
layout mattered here: `persist`, `load_folder_etags`, `pull_sidecars`,
`load_sidecar_etags`, `record_sidecar_read` and `apply_judgement` sit
textually beside the XMP push/reload functions but are called only
from `run_scan` (pulling a device's own past judgements out of the
sidecars a scan just walked), so they went to scan.rs and not xmp.rs.
`cells` came out at over 1,800 lines once its tests moved with it and
split further into cells.rs (windowed reads, trash, ordinals) and
spans.rs (collection scope, manual reordering, the capture-time
histogram) -- ten submodules rather than the nine first planned.
Previously-private items reached from a sibling module became
`pub(super)`, narrower than the whole-crate reachability one file gave
them. Tests moved with the code they test; the two test fixtures used
across more than one file (`scanned`, and develop.rs's
`session_with_a_left_half_subject` in the matching commit) joined the
shared `test_support` module alongside the existing `entry`/
`with_images`/`image_ids` helpers. `mod.rs` re-exports every module's
public items under `library::`, including the `pub(crate)`
`test_support` module `repairs.rs` reads its fixtures from, so no file
outside `library` needed a change.
The previous commit split develop.rs the same way; taken alone it left
dr-ui without library.rs, so that intermediate commit does not build on
its own. This one restores it.
