Sanitizes wishlist track data for consistent backend/frontend handling, enhances wishlist process state reporting for better UI sync, and refactors frontend modal logic to prevent auto-show conflicts and ensure user-driven visibility. Also improves polling and rehydration to keep frontend state in sync with server-side auto-processing.
Introduces a new atomic cancel system (V2) for download tasks, ensuring single-step cancellation with proper worker slot management and backend-driven state. Updates both backend (web_server.py) and frontend (script.js) to support V2 cancel API, persistent cancel state, and improved UI handling for cancelling tasks, eliminating race conditions and dual state management.
Introduces backend API endpoints and frontend logic to persist and restore artist download bubble state across page refreshes. Snapshots are saved and hydrated with live download status, ensuring continuity of user progress and UI state. Includes debounce logic for efficient snapshot saving and automatic cleanup of outdated or invalid snapshots.
Refactored download monitor to handle error and timeout retries directly and consistently, removing legacy retry methods. Improved batch completion logic to ensure batches are only marked complete when all tasks are truly finished, preventing premature completion. Updated client-side polling to never stop automatically, using exponential backoff on failures, and fixed worker counting to exclude post-processing tasks. Enhanced post-processing and verification workflows to avoid double completion callbacks and ensure proper task state transitions.
Introduces a new post-processing workflow in web_server.py that verifies file existence and integrity before marking download tasks as completed. Updates status handling to include a 'post_processing' state and reflects this in the frontend UI, ensuring users see accurate progress and preventing premature completion status for downloads.
Adds server-side validation and healing for download batch worker counts to prevent ghost workers and orphaned tasks, including periodic batch state checks and recovery logic. Enhances thread safety with batch-specific locks and improves error handling in worker slot management. On the frontend, implements exponential backoff for polling failures, validates server responses, and logs worker count discrepancies for better debugging and UI consistency.
Added debounced updates for the artist downloads section to prevent rapid UI refreshes. Enhanced debug logging and error handling for download status changes and bulk completion. Introduced a utility to force refresh all artist download statuses. Updated CSS for better spacing and overflow handling in artist bubble containers and images.
Introduces backend API and frontend integration for downloading missing tracks from artist albums and singles. Adds artist download bubbles, management modal, and related state/UI logic to script.js, with supporting styles in style.css. Also refactors some type hints in web_server.py for consistency.
