- Enhanced the SandboxManager to use a sharded locking mechanism for improved concurrency and performance.
- Replaced the global lock with shard-specific locks, allowing for lock-free reads and reducing contention.
- Updated methods for registering, retrieving, unregistering, and counting sandboxes to work with the new sharded structure.
- Improved documentation within the class to clarify the purpose and functionality of the sharding approach.
- 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.
- Introduced threading to handle Docker's stdout/stderr streams, improving thread safety and preventing race conditions.
- Replaced buffer-based reading with queue-based reading for stdout and stderr.
- Updated read methods to handle errors and end-of-stream conditions more gracefully.
- Enhanced documentation to reflect changes in the demuxing process.
- Improved error message handling by assigning the stderr output to a variable for better readability.
- Ensured consistent error reporting when a command fails, maintaining clarity in the output.
- Updated error handling to provide detailed stderr output when a command fails.
- Streamlined working directory and command rendering by combining operations into single lines.
- Simplified the command execution logic by removing unnecessary shell invocations.
- Enhanced working directory validation by directly using the `test` command.
- Improved command parsing with `shlex.split` for better handling of raw commands.
- Added checks to verify the existence of the specified working directory before executing commands.
- Updated command execution logic to conditionally change the working directory if provided.
- Included FIXME comments to address future enhancements for native cwd support in VirtualEnvironment.run_command.
- Added FIXME comments to indicate the need for unifying runtime config checking in AdvancedChatAppGenerator and WorkflowAppGenerator.
- Introduced sandbox management in WorkflowService with proper error handling for sandbox release.
- Enhanced runtime feature handling in the workflow execution process.
- 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.
