peter 367bcebc9f fix(downloads): revive the worker cancel branch and guard terminal writes (B-sub-1)
The cancel route writes status 'canceled' but the supervisor compared against
'cancelled', so its "a route stopped it -> kill the child, free the asset"
branch was dead code. A canceled job's child ran to completion and wrote 'done'
unconditionally over the route's 'canceled'; since 'done' holds the asset but
'canceled' does not, a later delete released the asset a second time, dropping
ref_count below the live holder count and deleting a file still in use.

Add app/downloads/status.py as the single source of truth for the lifecycle
literals (JobStatus StrEnum + the HOLDING / STOPPED_BY_ROUTE sets) and use it at
the safety-critical sites: the supervisor stop check, the route cancel, and
release_asset's holding set. Make the worker's terminal done/error writes
conditional on the row still being 'running' so a child finishing just after a
route cancel/pause can no longer resurrect it. Add the missing 'canceled'
supervisor regression test.

(The full literal sweep across the downloads surface is left for the E3
downloads owner-unification; this is the data-safety subset.)

Siftlode

Your YouTube subscriptions, the way a feed should work. Siftlode pulls every upload from the channels you follow into one clean, filterable feed — no algorithm deciding what you see, and no Shorts or livestream noise unless you want it. Self-hosted, multi-user, and private: your data stays on your own server.

Siftlode feed

Everything expensive (channels, videos, metadata) is fetched from YouTube once and stored locally, so filtering, searching and sorting are instant and don't burn API quota. Click a video to watch it in an in-app player that resumes where you left off — or open it on youtube.com so your own ad blocker and SponsorBlock keep working.

Features

  • A readable subscription feed — sort and filter by channel, tag, language, topic, length, upload date or watch state; hide channels without unsubscribing; save filter setups as named views.
  • Search all of YouTube from the feed — live results you can play, save or add to playlists like any other video; they stay temporary and out of your catalog unless you keep one.
  • Channel pages & a channel manager — per-channel stats and uploads, priorities, and your own tags to slice the feed by.
  • Playlists with two-way YouTube sync — build them locally, keep them in sync in both directions.
  • In-app player with resume, plus keyboard/scroll controls.
  • Download Center — save videos to the server with yt-dlp in a Plex-friendly layout (format presets, per-user storage quota), trim / crop / split & join them in a built-in editor, then save to your device, share with another user, or hand out a public watch link.
  • Plex library (optional) — point Siftlode at your own Plex server to browse and play its movies and shows alongside your feed, with watch state kept in sync.
  • Multi-user with per-user private state, a shared catalog, and a fair daily API-quota guard.
  • Self-hosted & private, with a first-run web setup wizard and the interface in English and Hungarian.

Quick start (self-hosting)

You don't need to build anything — Siftlode runs from a prebuilt public image, and all configuration (your admin account, Google sign-in, email) happens in a first-run web wizard. You need Docker with the Compose plugin.

1. Get the files and run the installer:

git clone https://git.b1fr0st.eu/peter/siftlode.git
cd siftlode
./install.sh          # Windows (PowerShell):  ./install.ps1

The installer generates a private .env (secrets), pulls the image, starts the app + database, and prints a one-time setup URL like http://localhost:8080/setup?token=….

2. Finish in your browser. Open that URL and follow the wizard:

  1. Admin account — the email + password you'll sign in with.
  2. Google sign-in (optional) — paste a Google OAuth client to enable "Sign in with Google" and pulling your YouTube subscriptions. Skip it to use email + password only.
  3. Email / SMTP (optional) — for verification/notification emails. Skip it and you (the admin) simply approve new accounts yourself.

Then sign in with your admin account. That's it. See docs/self-hosting.md for the full walkthrough.

Just trying it out? Press Enter at the installer's URL prompt to run on http://localhost:8080.

Build from source (alternative)

Prefer to build the image yourself instead of pulling it:

git clone https://git.b1fr0st.eu/peter/siftlode.git
cd siftlode
cp .env.example .env
# generate the two secrets and paste them into .env:
python -c "import secrets;print('SECRET_KEY='+secrets.token_urlsafe(48))"
python -c "import base64,os;print('TOKEN_ENCRYPTION_KEY='+base64.urlsafe_b64encode(os.urandom(32)).decode())"
docker compose up --build -d      # builds from the included Dockerfile

Open http://localhost:8080 and finish in the setup wizard as above. (Set a POSTGRES_PASSWORD in .env too.)

HTTPS / public access

Port 8080 over plain HTTP is fine for a LAN or a quick trial. For public access put a reverse proxy (Caddy, Nginx, Traefik…) in front to terminate TLS, and set the public URL (the installer prompt, or OAUTH_REDIRECT_URL in .env) to your https://… address — this also marks the session cookie secure. Add that same …/auth/callback URL to your Google OAuth client's authorized redirect URIs. Behind a proxy, also set TRUSTED_PROXY_IPS so the rate limiters see the real client IP and can't be bypassed via a forged X-Forwarded-For — see docs/self-hosting.md.

Updating & backups

docker compose -f docker-compose.selfhost.yml pull   # or: docker compose pull
docker compose -f docker-compose.selfhost.yml up -d

Database migrations run automatically on startup. Your data (accounts, subscriptions, playlists, the video catalog) lives in a Postgres volume — back it up with scripts/backup.sh (or backup.ps1 on Windows) and restore with scripts/restore.sh.

How it works

  • Shared catalog, private state. Channels and videos are stored once and shared; each user's subscriptions, tags, playlists and watch/save/hide state are private.
  • Cheap by design. Public reads are cached locally; a shared daily quota budget and a background scheduler keep unattended syncing within YouTube's free API limits. An optional API key lets backfill run without depending on a user's OAuth token.

Tech

FastAPI + PostgreSQL (SQLAlchemy, Alembic) backend; React + Vite + Tailwind + TanStack Query frontend; packaged as a single Docker image with Docker Compose.
