- B1 (sticky errored asset): get_or_create_asset now resets a reused status=='error'
asset back to 'pending' (+clears the error), so a fresh enqueue/edit of a once-failed
(source,format) pair actually re-downloads instead of the worker short-circuiting the
new job with the stale error. Errored assets carry no expires_at, so without this the
pair was permanently poisoned for all users until someone hit resume.
- B2 (ref_count leak): _release_asset counts 'error' as a holding state, so deleting an
errored job decrements the ref_count that enqueue always incremented (the worker never
decrements on failure). Errored rows are deliberately NOT deleted here — a concurrent
B1 reuse could otherwise be lost-updated + FK-nulled; the row is fileless and harmless.
- B3: admin storage dashboard reads sysconfig.get_int(db,'download_total_max_bytes')
(the admin-editable DB value GC enforces) instead of the raw env default.
- B4: the single-trim branch of normalize_edit_spec guards its float() coercion like the
crop/segments branches — a malformed trim now yields a 400, not an unhandled 500.
- B5: formats.normalize guards int(max_height) → falls back to "best" instead of 500.
Reviewed (race in an earlier B2 draft caught + fixed); localdev boots, B4/B5 unit-verified.
- C3: `_reference_url` (downloads.py) and public.py's inline source-URL block were
the same rule → extract `service.reference_url(job, asset)`; both surfaces now
share it so the "downloaded from" link can't drift between them.
- C4: Content-Disposition filename derivation (ext pick + doubled-ext strip + join)
was duplicated in download_file and watch_file → extract
`storage.download_filename(display_name, container, path)`.
- C5: inline the one-line `_clean_basename` passthrough (folded into C4).
- C6: the `db.get(MediaAsset, job.asset_id) if job.asset_id else None; _serialize(...)`
resolve-then-serialize dance was repeated across 6 single-job handlers → fold into
`_serialize_job(db, job)`. (File-serving handlers that use the asset for their own
checks keep their explicit resolve.)
Behavior-neutral; ruff/parse clean, localdev boots, downloads routes load.
A download whose source title exceeded 255 chars (e.g. a recipe baked into a
Facebook video's title) failed with a StringDataRightTruncation: the worker
auto-fills an empty display_name from the title, which overflows the 255-char
column. Clip the title to 255 at every point it flows into display_name (worker
completion paths + enqueue); the full title is untouched on the asset. Pre-existing
latent bug, surfaced by an unusually long title.
Release v0.31.1.
A queued/downloading row previously showed the bare video id and no thumbnail because asset
metadata was only filled when the download completed. Now:
- service.populate_from_catalog fills title/uploader/thumbnail/date/duration at enqueue from
our own Video/Channel catalog (0 network cost) — feed downloads look right instantly
- worker fills the same from yt-dlp's info_dict on the first progress event (covers ad-hoc
URLs / catalog misses), best-effort, never fails a download
Verified: a paused feed download now shows its real title, channel, thumbnail and duration.
The .gitignore 'downloads/' pattern for the DOWNLOAD_ROOT bind mount also matched the
backend/app/downloads source package, so formats.py/storage.py/service.py never got
committed with M2. Anchor the ignore to '/downloads/' (repo root only) and add the package.
storage.sanitize() now handles arbitrarily messy titles (emoji, ZWJ, fullwidth, clickbait
punctuation): NFKC-normalize, drop emoji/symbol/control unicode categories, collapse
repeated punctuation, underscore-join words -> space-free paths. Accents (HU/DE) preserved,
no ASCII folding. Plex layout uses _-_ separators + Season_{year}.
