The Files library starts here. A user's every download, clip and upload now
lands in a source folder made per origin (YouTube, Plex clips, uploads, one per
other site), decided once in downloads/folders.py at every place a job is made.
How long a file stays moves from the shared asset to the user's job: stamped
from its folder when it is done, never for a file the user keeps. The GC warns
each user once, then takes the expired file out of their library; the cache cap
never evicts a kept file, and an evicted one leaves every holder's library.
The media mount is /files now (FILES_ROOT, FILES_HOST_PATH, volume
siftlode_files); docs/self-hosting.md says how to carry an old volume over.
Migration 0102 places every existing job and carries each done file's expiry
over from its asset.
safe_abs_path takes a missing path and answers None, which drops one baselined
type error.
- Every ffmpeg/ffprobe over a library file names the demuxers it may use
(edit.INPUT_GUARD; a downloaded thumbnail edit.THUMB_GUARD): a playlist-type
demuxer would read local paths named inside a user's upload.
- A re-encode ends on an even frame (edit.EVEN_FRAME): an odd 4:4:4/RGB source
failed its conversion; a clip stores the frame its file has.
- An upload counts against its owner's cap from the moment it lands (queued, or
kept after a failed conversion) — the footprint, the GC's cap and the admin
view read one ON_DISK predicate — and a conversion that outgrows the cap is
refused, keeping the original.
- The converted name keeps _a{id} (a dotted bare name once lost it and two
uploads shared a file); a converted file placed but not committed is removed,
and the orphan sweep enters .uploads; the LRU cap never evicts an upload.
- Ingest judges the extension the file is stored under; a failed conversion is
convert_failed / upload_missing, reports the "converting" phase, and notifies
as an upload. Job statuses in routes/downloads use JobStatus.
