The #891 'also remove image/sidecar-only folders' toggle never worked. Job settings are
persisted as a nested dict under repair.jobs.<id>.settings (RepairWorker.set_job_settings),
but the scan read flat keys — repair.jobs.empty_folder_cleaner.remove_residual_files — which
never matched, so it always fell back to the False default and skipped every image/.lrc-only
folder. (remove_junk_files had the same mismatch but its default is True, which is why only the
truly-empty 'deleted' folder kept showing up.) Now reads from .settings like get_job_config /
lossy_converter do.
The pure dir_is_removable logic was already correct + tested; the bug was purely the config
read in scan(), which had no test. Added two scan-level regression tests driving the real
JobContext + a config that stores the toggle the way the UI does.
Reorganize leaves a cover.jpg (and other leftovers) behind when it moves an album,
and the Empty Folder Cleaner is too conservative to sweep them. Two complementary
fixes over one shared 'residual file' predicate (core/library/residual_files.py:
junk + cover/scan images + lyric/metadata sidecars), so both features agree on what
a dead folder is.
1. Reorganize (proactive): _delete_album_sidecars now sweeps ALL residual files when
a source dir has no audio left — previously only a fixed list of cover NAMES, so
back.jpg / disc.png / .webp survived and kept the folder un-prunable.
2. Empty Folder Cleaner (the request): new opt-in 'Remove Residual Files' setting
(default off) treats a folder holding only images/sidecars/junk as removable —
cleans the existing backlog + arbitrary names. Auto-renders as a UI toggle.
Safe by construction: whitelist-only (a booklet.pdf / video / .txt is real content
and kept), reorganize sweep gated on no-audio, cleaner re-checks at apply time.
20 new tests; 272 reorganize/repair/empty-folder green.
A maintenance job to keep the music library tidy — finds empty folders left behind
by imports/relocations/deletions (empty artist/album dirs, or dirs holding only OS
junk like .DS_Store/Thumbs.db) and removes them.
Safety is the focus (deleting directories is destructive):
- only TRULY empty folders are flagged — a folder with a cover image or any audio
is never touched; only OS-junk files count as "no real content" (a setting),
- the library root + symlinked dirs are never removed,
- walks bottom-up so a parent left empty by its removable children cascades,
- the apply handler RE-CHECKS emptiness at delete time, so a folder that gained a
file between scan and apply is left alone.
dir_is_removable + remove_empty_folder are pure/injectable seams. Wired through the
job registry, repair_worker apply handler (_fix_empty_folder), fixable-types, and
the findings UI. Opt-in (default off), weekly interval.
Tests (10): removable decision (empty / real-file / surviving-subdir / junk-only /
strict mode) + apply re-check (removes empty + junk, refuses content/root/symlink).
Repair + integrity suites green; ruff clean.
