DifyCli and AppAssets used hardcoded absolute paths under /tmp/.dify/,
causing concurrent sandbox sessions on the same host (e.g. SSH provider)
to overwrite each other's config files and CLI binaries.
- Add Sandbox.id property (uuid4 hex) as a stable, path-safe identifier
independent of provider-specific environment IDs
- Convert DifyCli/AppAssets from static constants to per-sandbox instances
namespaced under /tmp/.dify/{sandbox.id}/
- Replace all vm.metadata.id references with sandbox.id
- Replace upload_file with heredoc-based pipeline step in session.py to
reduce round-trips
Updated multiple modules to utilize gevent for concurrency, ensuring compatibility with gevent-based WSGI servers. This includes replacing threading.Thread and threading.Event with gevent.spawn and gevent.event.Event, respectively, to prevent blocking and improve performance during I/O operations.
- Refactored SandboxBuilder, Sandbox, CommandFuture, and DockerDemuxer to use gevent.
- Added detailed docstrings explaining the changes and benefits of using gevent primitives.
This change enhances the responsiveness and efficiency of the application in a gevent environment.
- Added sandbox archive upload and download proxy endpoints with signed URL verification.
- Introduced security helpers for generating and verifying signed URLs.
- Updated file-related API routes to include sandbox archive functionality.
- Refactored app asset storage methods to streamline download/upload URL generation.
- Added AttrMap and AttrKey classes for type-safe attribute storage.
- Implemented AppAssetsAttrs and SkillAttrs for managing application and skill attributes.
- Refactored Sandbox and initializers to utilize the new attribute management system, enhancing modularity and clarity in asset handling.
- 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.
