- 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.
- 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
- Add helpers.py with connection management utilities:
- with_connection: context manager for connection lifecycle
- submit_command: execute command and return CommandFuture
- execute: run command with auto connection, raise on failure
- try_execute: run command with auto connection, return result
- Add CommandExecutionError to exec.py for typed error handling
with access to exit_code, stderr, and full result
- Remove run_command method from VirtualEnvironment base class
(now available as submit_command helper)
- Update all call sites to use new helper functions:
- sandbox/session.py
- sandbox/storage/archive_storage.py
- sandbox/bash/bash_tool.py
- workflow/nodes/command/node.py
- Add comprehensive unit tests for helpers with connection reuse
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.
- Add _DockerDemuxer to properly separate stdout/stderr from multiplexed stream
- Fix binary header garbage in Docker exec output (tty=False 8-byte header)
- Fix LocalVirtualEnvironment.get_command_status() to use os.WEXITSTATUS()
- Update tests to use Transport API instead of raw file descriptors
- Introduced Command node type in workflow with associated UI components and translations.
- Enhanced SandboxLayer to manage sandbox attachment for Command nodes during execution.
- Updated various components and constants to integrate Command node functionality across the workflow.
