# fix(prowlarr): prevent silent loss of indexer seed limits Related to #795, though not a fix for that specific (closed) report — see note below. ## Problem With "Use Prowlarr seed preferences" enabled, ~5–10% of torrent grabs are added to the download client without their configured share limits and seed indefinitely (∞ ETA in qBittorrent). Seed limits are resolved once at search time. `get_indexer_seed_settings()` builds on `get_indexers()`, which swallows all API errors and returns `[]`. A transient failure of the `/api/v1/indexer` call therefore produces an empty settings dict that is indistinguishable from "no limits configured", while the search itself (separate HTTP calls) still succeeds. Every result from that search is cached without `configuredSeedTimeMinutes`; grabbing one sends the torrent to the client with no limits. Compounding factors: `cache_release()` is last-write-wins by GUID, so one degraded search can strip enrichment from a previously good cache entry; and the retry fields persisted at queue time snapshot the same missing values, so retries reproduce the failure. ## Changes - **`api.py`** — `get_indexers()` / `get_enabled_indexers_detailed()` gain a keyword-only `raise_on_error` (default `False`, existing behavior unchanged). `get_indexer_seed_settings()` uses it, so fetch failures now propagate and an empty dict strictly means "nothing configured". - **`source.py`** — searches fetch settings via `_fetch_indexer_seed_settings()`, which maintains a module-level last-known-good copy (merged on each success) and falls back to it with a warning when the fetch fails. After one successful fetch, results can no longer be cached un-enriched. - **`handler.py`** — grab-time safety net in `_resolve_download()`: if seed preferences are enabled, the release is a torrent, and no configured limits are present in the cached result, the handler re-resolves the limits from Prowlarr for that indexer (`restrict_to=[indexerId]`) before adding to the client. If limits still can't be resolved, a warning is logged so the condition is visible instead of silent. - **Tests** — regression coverage: last-known-good fallback (success updates cache, failure falls back, failure with no history returns empty, fallback copy is mutation-safe) and grab-time fallback (used when enrichment is missing, tolerates Prowlarr being down, skipped when enrichment is present). Existing test stubs for `get_enabled_indexers_detailed` updated to accept the new kwarg. ## Testing - `uv run pytest tests/prowlarr/test_handler.py tests/prowlarr/test_source.py tests/prowlarr/test_integration_handler.py` — 93 passed, 2 skipped (Python 3.14.4) - Full `tests/prowlarr` run has 11 pre-existing failures on this environment (Windows path-separator assertions in the qBittorrent/NZBGet/SABnzbd/Transmission client tests, e.g. `/downloads/x` vs `\downloads\x`); confirmed these also fail on unpatched `main` and are unrelated to this change - `uv run ruff check` / `ruff format --check` — clean on touched files - `uv run basedpyright` — 0 errors on touched files No behavior change when `PROWLARR_USE_SEED_PREFERENCES` is disabled; the fallback path only activates when the preference is on and enrichment is missing for a torrent. --- **Note on #795:** this PR references #795 for background context on the seed-limits feature, but it does not fix that report — #795 was about seed limits not being converted/applied at all (a units mismatch), and was already fixed by #946 / #959. This PR fixes a separate, still-present bug: `get_indexers()` silently swallowing transient API errors, which intermittently drops seed limits even when the feature is otherwise working correctly.
Test Suite
This directory contains the test suite for Shelfmark. Tests are organized by scope and component.
Quick Start

uv run pytest tests/ -v -m "not integration and not e2e"
# Run all Python static analysis (lint, format, typecheck, dead code)
make python-checks
# Run E2E API tests against a running app stack

Test Types
Unit Tests
Fast tests that mock external dependencies. Run these frequently during development.
uv run pytest tests/prowlarr/ -v -m "not integration"
What they test:
- Download client logic (status mapping, URL handling, error cases)
- 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

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>
