From eb59a87dac4dcccf9b4891b8e3c7403772e6076a Mon Sep 17 00:00:00 2001 From: Matt Duran Date: Sun, 19 Oct 2025 15:46:55 -0700 Subject: [PATCH] Fix resource leaks, crashes, and add comprehensive error handling MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit This commit addresses multiple critical issues in the plugin: ## Fixes - Fix #29: Crash when playing Live TV (ArgumentException: Guid can't be empty) - Fix #60: Crash when playing movies outside TubeArchivist library - Fix resource leak: HttpClient and HttpClientHandler were never disposed - Fix infinite loop in PluginConfiguration caused by property setters ## Changes ### Resource Management (IDisposable) - Implement IDisposable pattern for Plugin class - Properly dispose HttpClient and HttpClientHandler on shutdown - Unsubscribe from PlaybackProgress and UserDataSaved events - Prevent memory leaks and socket exhaustion ### Collection Validation with Caching - Add CacheTubeArchivistCollectionId() for O(1) collection lookups - Implement IsItemInTubeArchivistCollection() with: - Early type checking (reject non-Episode items immediately) - Cached collection ID matching for efficient validation - Depth limiting (max 10 levels) to prevent infinite loops - Null-safe parent chain traversal - Filter collection query to use Folder type only (avoids ghost CollectionFolder entries) - Add RefreshTubeArchivistCollectionId() for configuration changes - Fallback to hierarchy-based checking when cache unavailable ### Async Error Handling - Convert async void event handlers to proper async void → async Task pattern - Add top-level exception handling in OnPlaybackProgress and OnWatchedStatusChange - Wrap async logic in try-catch blocks with proper logging - Add ConfigureAwait(false) to all await calls ### Configuration Stability - Add value change checks in PluginConfiguration property setters - Prevent infinite loops from repeated property assignments during deserialization - Only refresh cache/reconnect when values actually change ### Debugging & Logging - Add comprehensive logging throughout collection validation - Log parent chain traversal for troubleshooting - Log all collections found during cache initialization - Add detailed sync progress logging ## Performance Improvements - Collection validation: O(n) hierarchy traversal → O(1) cached lookup - Reduced redundant API calls and hierarchy traversals - Fixed memory leak from undisposed HttpClient ## Testing All 23 existing tests pass.
