- 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.
- 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
- Merge origin/feat/llm-node-support-tools branch
- Fix unused variable tenant_id in dsl.py
- Add None checks for app and workflow in dsl.py
- Add type ignore for e2b_code_interpreter import
