Changes

🚀 Feature Release - Skip Duplicate Downloads with Plex Existence Checking

Overview

Adds intelligent duplicate detection to prevent downloading content that already exists on accessible Plex servers. Includes multi-server support, role-based checking, and performance optimizations for shared Plex environments.

Key Updates

Plex Configuration Enhancements

• Skip duplicate downloads: New skipIfExistsOnPlex setting checks accessible Plex servers before downloading
• Server URL configuration: Configure Plex server URL directly from UI (previously environment variable only)
• Multi-server awareness: Searches owner's server and all shared servers you have access to
• Role-based checking: Primary users check all accessible servers, friend users check only the owner's server
• Efficient API usage: Server list cached per workflow to minimize plex.tv API calls

How it works:

1. User adds content to watchlist
2. During reconciliation, Pulsarr checks if content exists on any accessible Plex server
3. If found, skips adding to Radarr/Sonarr (no download triggered)
4. If not found, proceeds with normal download workflow

Configuration:

• Enable via Plex Configuration page → "Skip if exists on Plex"
• Or set environment variable: SKIP_IF_EXISTS_ON_PLEX=true
• Requires primary token with server access

Performance Optimizations

• Parallel server checks: All accessible servers checked simultaneously for faster results
• Early termination: Stops searching once content is found on any server
• Concurrency control: p-limit ensures optimal performance without overwhelming servers
• Resilient fallback: Owner server always checked even during plex.tv outages

Technical Changes

• Refactored Plex utilities into modular components (labels, metadata, sessions, resources)
• Enhanced error handling with cache clearing on configuration updates
• Improved GUID parsing and label update logic in watchlist workflow
• Per-server access tokens for improved authentication across shared servers

Migration & Compatibility

Database migration - Automatic on startup, adds skipIfExistsOnPlex setting (defaults to disabled)
