Thirty-nine spawn sites in dr-ui, and one in the Android entry point,
called std::thread::spawn or a Builder of their own, and most of the
threads they started were <unnamed> in a panic message or a profiler.
Each now calls executors::spawn with its executor and a role, so the thread is
named <executor>:<role> — net:sync, decode:thumbs, io:catalog-open —
and knows which executor it is on. The three that already set a name
(automation, import, prefetch) keep their name as the role.
Behaviour is unchanged: each job still gets a thread of its own when it
starts, and spawn panics where std::thread::spawn did.
The module's documentation now says how a job is assigned: by what it
spends its time on, so a sweep that fetches bytes and then decodes them
is Decode, and a sidecar write that touches the catalog is Network.
Left as they were: the segmentation and refine workers in masks_ui.rs,
which another change is reworking, and test-only threads.
A copy becomes a duplicate only once its capture time is read, and on a
fresh library that is the sweep, not the scan: the sidebar row stayed
hidden until the next launch. The count is refreshed when a sweep that
dated anything finishes.
Also says on a group left out of the plan that nothing will move, drops
an unused method, and names the review's completion callback type for
clippy.
"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.
dr_ui::duplicates is the half of #67 that touches files. The check reads
each copy's first and last megabyte by range through the backend and
hashes them (or compares stored content hashes where every copy has one),
keeps the probes in the catalog, and reads each copy's sidecar: a group
whose bytes differ, whose copies cannot be read, or whose develop edits
differ is left out and the review says why.
Consolidating a group carries the one edit onto the survivor's sidecar
where it has none, moves the other copies into the trash, and then
commits dr_catalog::duplicates::consolidate. A failure after the first
move puts the files and the sidecar back; a run that died between the
moves and the commit is finished by the next one, which finds each moved
file at its trash path.
Tested end to end on a folder library of real files: the copies land in
.darkroom-trash, the skipped groups are untouched, the edit reaches the
survivor, a catalog failure moves everything back, and restore returns
the copies byte for byte.
