This commit removes unnecessary and redundant comments from multiple JavaScript modules, streamlining the code and improving readability. No functional changes were made; only comment cleanup and minor formatting adjustments.
Moved CommonUtils.js, ImageUtils.js, and LoggerUtils.js to a new utils/ directory and updated all import paths accordingly throughout the codebase. Also increased the default canvas width in Canvas.js from 512 to 1024.
Extracted and centralized common utility functions such as createCanvas, normalizeToUint8, and generateUniqueFileName in CommonUtils.js to reduce code duplication. Added createImageFromSource to ImageUtils.js. Refactored db.js to use a helper for IndexedDB requests, simplifying error handling and reducing boilerplate. Updated CanvasIO.js, CanvasLayers.js, and Canvas_view.js to use the new utilities.
Replaced manual logger setup in CanvasRenderer, ImageCache, Mask_tool, and db modules with the createModuleLogger utility for cleaner and more consistent logging initialization.
Enhanced the canvas save mechanism to ensure unique file names per node, prevent concurrent saves and executions, and handle missing files more robustly. Switched all logger levels to DEBUG for detailed tracing. Added fallback logic for file naming, improved error handling, and ensured that empty canvases are not saved. These changes improve reliability and traceability of canvas operations, especially in multi-node scenarios.
Images used in canvas layers are now stored in a dedicated 'CanvasImages' object store in IndexedDB, referenced by unique imageId. The Canvas class and db.js were updated to support saving, loading, and removing images by imageId, improving performance and scalability. Legacy imageSrc handling is preserved for backward compatibility, and the database schema version was incremented to 2 to support the new store.
Standardized spacing and object literal formatting across multiple JS files for improved readability and consistency. No functional changes were made. Minor Python formatting adjustment for line length in canvas_node.py.
Introduces a 'Clear Cache' button to the Canvas widget UI, allowing users to clear all saved canvas states. Implements the clearAllCanvasStates function in db.js to handle the deletion of all canvas state entries from the database.
Replaced localStorage usage in Canvas.js with asynchronous IndexedDB operations for saving, loading, and removing canvas state. Added a new db.js module to handle IndexedDB interactions, improving scalability and reliability of state persistence.
