From 71207bc935afa5b36412efa081ee1fea26812bc8 Mon Sep 17 00:00:00 2001 From: Lukas Date: Fri, 17 Oct 2025 11:51:16 +0200 Subject: [PATCH] feat: Complete WebSocket integration with core services - Enhanced DownloadService broadcasts for all queue operations - Download progress, complete, and failed broadcasts with full metadata - Queue operations (add, remove, reorder, retry, clear) broadcast queue status - Queue control (start, stop, pause, resume) broadcasts state changes - AnimeService scan progress fully integrated with ProgressService - Scan lifecycle events (start, update, complete, fail) broadcasted - Progress tracking via ProgressService to scan_progress room - ProgressService WebSocket integration - Broadcast callback registered during application startup - All progress types route to appropriate rooms - Throttled broadcasts for performance (>1% changes) - Comprehensive integration tests - Test download progress and completion broadcasts - Test queue operation broadcasts - Test scan progress lifecycle - Test progress service integration - End-to-end flow testing - Updated infrastructure documentation - Detailed broadcast message formats - Room structure and subscription patterns - Production deployment considerations - Architecture benefits and scalability notes --- infrastructure.md | 278 ++++++++++- instructions.md | 7 - src/server/services/download_service.py | 134 ++++- .../integration/test_websocket_integration.py | 470 ++++++++++++++++++ 4 files changed, 868 insertions(+), 21 deletions(-) create mode 100644 tests/integration/test_websocket_integration.py diff --git a/infrastructure.md b/infrastructure.md index 8ee77b7..75c295f 100644 --- a/infrastructure.md +++ b/infrastructure.md @@ -546,9 +546,9 @@ Implemented comprehensive REST API endpoints for download queue management: -
