- Introduced `GetUploadUrlPayload` and `BatchUploadPayload` models for handling file uploads.
- Implemented `AppAssetFileUploadUrlResource` for generating pre-signed upload URLs.
- Added `AppAssetBatchUploadResource` to support batch creation of asset nodes from a tree structure.
- Enhanced `AppAssetService` with methods for obtaining upload URLs and batch creation of assets.
- Removed checksum handling from file creation to streamline the process.
- Introduced AppBundleService for managing app bundle publishing and importing, integrating workflow and asset services.
- Added methods for exporting app bundles as ZIP files, including DSL and asset management.
- Implemented source zip extraction and validation to enhance asset import processes.
- Refactored asset packaging to utilize AssetZipPackager for improved performance and organization.
- Enhanced error handling for bundle format and security during import operations.
- Updated binary files for Dify CLI on various platforms (darwin amd64, darwin arm64, linux amd64, linux arm64).
- Refactored skill compilation in LLMNode to improve clarity and maintainability by explicitly naming parameters and incorporating AppAssets for base path management.
- Minor fix in AppAssetFileTree to remove unnecessary leading slash in path construction.
- Moved sandbox-related classes and functions into a dedicated module for better organization.
- Updated the sandbox initialization process to streamline asset management and environment setup.
- Removed deprecated constants and refactored related code to utilize new sandbox entities.
- Enhanced the workflow context to support sandbox integration, allowing for improved state management during execution.
- Adjusted various components to utilize the new sandbox structure, ensuring compatibility across the application.
- Introduced DraftAppAssetsInitializer for handling draft assets.
- Updated SandboxLayer to conditionally set sandbox ID and storage based on workflow version.
- Improved asset initialization logging and error handling.
- Refactored ArchiveSandboxStorage to support exclusion patterns during archiving.
- Modified command and LLM nodes to retrieve sandbox from workflow context, supporting draft workflows.
- Introduce _app_id attribute to store application ID from system variables
- Add _get_app_id method to retrieve and validate app_id
- Update on_graph_start to log app_id during sandbox initialization
- Integrate ArchiveSandboxStorage for persisting and restoring sandbox files
- Ensure proper error handling for sandbox file operations
- Add AppAssetsInitializer to load published app assets into sandbox
- Refactor VMFactory.create() to VMBuilder with builder pattern
- Extract SandboxInitializer base class and DifyCliInitializer
- Simplify SandboxLayer constructor (remove options/environments params)
- Fix circular import in sandbox module by removing eager SandboxBashTool export
- Update SandboxProviderService to return VMBuilder instead of VirtualEnvironment
The original fix seems correct on its own. However, for chatflows with multiple answer nodes, the `message_replace` command only preserves the output of the last executed answer node.
- Simplified the SandboxLayer initialization by removing unused parameters and consolidating sandbox creation logic.
- Integrated SandboxManager for better lifecycle management of sandboxes during workflow execution.
- Updated error handling to ensure proper initialization and cleanup of sandboxes.
- Enhanced CommandNode to retrieve sandboxes from SandboxManager, improving sandbox availability checks.
- Added unit tests to validate the new sandbox management approach and ensure robust error handling.
