## Problem
Shelfmark can lose track of hybrid v1/v2 torrents after qBittorrent
completes their metadata download.
Shelfmark initially identifies the torrent by its v1 infohash. Once
metadata resolves, qBittorrent may switch the torrent’s primary `hash`
to the truncated v2 hash, causing lookups using the original v1 hash to
return nothing.
For example:
- v1: `edf46c7f938a3c678081734d7bff8b9c652ba5e5`
- qBittorrent `hash`: `0bed5f40753b342cb143e83c2b21924cc8474731`
- full v2:
`0bed5f40753b342cb143e83c2b21924cc847473134e44d1bd300bdc58c13010f`
At that point, querying `/api/v2/torrents/info` with the original v1
hash returns no records. Querying with the new primary hash works, and
the returned record still contains the original hash in `infohash_v1`.
`find_existing()` also ignored its provided category, so audiobook
torrents fall back to the default ebook category instead. This means the
fallback method for a mismatched download ID never occurs for
audiobooks, leading to a "failed" download that is actually successful
in qBittorrent. As a result, the downloaded files are not automatically
transferred/hardlinked to the output directory.
## Fix
- Match torrents against `hash`, `infohash_v1`, and `infohash_v2`.
- Wait for magnet metadata to finish downloading before returning the
torrent ID.
- Return qBittorrent’s current primary `hash`.
- Search the provided category first, then the configured default, and
finally the full torrent list.

- Bencode encoding/decoding for torrent files
- Hash extraction from magnet links and .torrent files
- Protocol detection (torrent vs usenet)
- Release cache operations
- Handler download flow logic
- User database (CRUD, settings, OIDC subject linking)
- OIDC authentication (group claims, user provisioning, route handlers)
- Admin user management API (create, update, delete, password, per-user settings)
- Multi-user download queue filtering and per-user overrides
- Settings configuration (OIDC fields, show_when conditions)
E2E Tests
Test the full application through its HTTP API. Require the app to be running.
uv run pytest tests/e2e/ -v -m e2e

Integration Tests
Test against real services (qBittorrent, Transmission, etc.). Require the full Docker test stack.
# Start the test stack first
docker compose -f docker-compose.test-clients.yml up -d
# Run integration tests
docker compose -f docker-compose.test-clients.yml exec shelfmark uv run pytest tests/prowlarr/ -v -m integration

monkeypatch.setattr(
"shelfmark.module.config.get",
lambda key, default="": {"KEY": "value"}.get(key, default),
)
# Test your code
result = my_function()
assert result == expected
E2E Test Example
import pytest
from .conftest import APIClient, DownloadTracker
@pytest.mark.e2e
class TestMyEndpoint:
def test_endpoint_works(self, protected_api_client: APIClient):
resp = protected_api_client.get("/api/my-endpoint")
assert resp.status_code == 200
def test_with_cleanup(
self,
protected_api_client: APIClient,
download_tracker: DownloadTracker,
):
# Track IDs for automatic cleanup after test
download_tracker.track("some-id")
# ... test code ...

Expected Skips
Some tests skip when external services aren't available. This is normal:
- "No metadata providers available" - Metadata provider not responding
- "Prowlarr not configured" - Prowlarr settings not set up
- "No releases found" - No indexers configured in Prowlarr
- "Legacy search source unavailable" - Direct download source offline
- "Transmission/qBittorrent not available" - Docker test stack not running
Troubleshooting
Tests can't connect to app
# Check the app/container is running
docker ps
# Check app logs
docker logs <your-shelfmark-container>
Import errors
# Sync the local Python environment first
uv sync --locked --extra browser
# Then run tests from the repo root
uv run pytest ...
Integration tests failing
# Make sure test stack is running
docker compose -f docker-compose.test-clients.yml up -d
# Check client containers
docker ps | grep -E "qbittorrent|transmission|deluge|nzbget|sabnzbd"
Stale test data
Restart the container to reset the in-memory queue between test runs:
docker restart <your-shelfmark-container>
