A bare host like '192.168.1.5:8080' or 'qbittorrent.lan:8080' (no scheme)
is what users naturally type, but requests then raises 'No connection
adapters were found for ...' — it can't pick an http/https adapter, and a
bare host:port even gets misparsed as scheme=host. This surfaced as the
generic 'qbittorrent probe failed' with a 'login error: No connection
adapters were found' in the logs.
Add normalize_client_url() in torrent_clients/base: default a missing scheme
to http:// (+ trim trailing slash), and route all three adapters'
_load_config through it. Transmission normalizes the base before appending
/transmission/rpc.
Tests: normalizer unit cases + per-adapter regression (bare host -> http://).
Note: usenet adapters (sabnzbd/nzbget) share the same pattern and need the
same treatment in a follow-up.
Second commit in the torrent + usenet rollout. SoulSync now speaks
three different BitTorrent client APIs through one uniform adapter
contract — picks the active client by config and dispatches the same
verbs to whichever backend the user uses. Each adapter handles its
own auth quirk (qBit cookie + CSRF Referer, Transmission session-id
renegotiation, Deluge JSON-RPC session) and maps native state
strings onto a shared 7-value set so the rest of the app stays
client-agnostic.
- core/torrent_clients/base.py: TorrentClientAdapter Protocol +
TorrentStatus dataclass. Eight verbs: is_configured, check_connection,
add_torrent (URL/magnet), add_torrent_file (raw bytes), get_status,
get_all, remove, pause, resume.
- core/torrent_clients/__init__.py: adapter_for_type factory +
get_active_adapter that reads torrent_client.type each call so
settings changes take effect without restart.
- core/torrent_clients/qbittorrent.py: WebUI v2 adapter. Cookie auth
via /api/v2/auth/login, transparent 403 re-login, Referer header
to satisfy qBit's CSRF guard. add_torrent returns the just-added
hash via /torrents/info sort=added_on (qBit's add endpoint doesn't
echo the hash).
- core/torrent_clients/transmission.py: RPC adapter. Auto-resolves
bare host URLs to /transmission/rpc, handles the 409 + new
X-Transmission-Session-Id renegotiation transparently, accepts
HTTP basic auth. add_torrent_file base64-encodes payload per spec.
- core/torrent_clients/deluge.py: Deluge 2.x JSON-RPC adapter.
Password-only auth, distinguishes magnet vs HTTP URL at the RPC
method layer, applies category via Label plugin (best-effort —
label plugin is optional).
- core/connection_test.py: 'torrent_client' branch picks the right
adapter, runs check_connection, surfaces a per-client error
message.
- config/settings.py: torrent_client.{type, url, username, password,
category, save_path} defaults + torrent_client.password in the
encrypted-at-rest secrets list.
- web_server.py: 'torrent_client' added to the /api/settings POST
allow-list so saved config persists.
- webui/index.html: new Torrent Client panel on the Indexers &
Downloaders tab — client-type dropdown, URL, username, password,
category, optional save path, Test Connection.
- webui/static/settings.js: load/save wiring + testTorrentClientConnection.
- webui/static/helper.js: WHATS_NEW + VERSION_MODAL_SECTIONS entry.
