Implemented full WSS support with TLS configuration - Added handshake timeout and connection state tracking - Created comprehensive test suite with 13+ WSS unit tests - Added Python-to-Python WebSocket peer-to-peer tests - Implemented multiaddr parsing for /ws, /wss, /tls/ws formats - Added connection state tracking and concurrent close handling - Created standalone WebSocket client for testing - Fixed circular import issues with multiaddr utilities - Added debug tools for WebSocket URL testing All WebSocket transport functionality is complete and working. Tests demonstrate WebSocket transport works correctly at the transport layer. Higher-level libp2p protocol compatibility issues remain (same as JS interop). --- debug_websocket_url.py | 65 ++ libp2p/transport/__init__.py | 16 +- libp2p/transport/transport_registry.py | 78 +- libp2p/transport/websocket/connection.py | 60 +- libp2p/transport/websocket/listener.py | 97 +- libp2p/transport/websocket/multiaddr_utils.py | 202 ++++ libp2p/transport/websocket/transport.py | 135 ++- test_websocket_client.py | 243 +++++ tests/core/transport/test_websocket.py | 888 ++++++++++++++++++ tests/core/transport/test_websocket_p2p.py | 516 ++++++++++ tests/interop/test_js_ws_ping.py | 103 +- 11 files changed, 2294 insertions(+), 109 deletions(-) create mode 100644 debug_websocket_url.py create mode 100644 libp2p/transport/websocket/multiaddr_utils.py create mode 100755 test_websocket_client.py create mode 100644 tests/core/transport/test_websocket_p2p.py diff --git a/debug_websocket_url.py b/debug_websocket_url.py new file mode 100644 index 000000000..328ddbd56 --- /dev/null +++ b/debug_websocket_url.py @@ -0,0 +1,65 @@ +#!/usr/bin/env python3 +""" +Debug script to test WebSocket URL construction and basic connection. +""" + +import logging + +from multiaddr import Multiaddr + +from libp2p.transport.websocket.multiaddr_utils import parse_websocket_multiaddr + +# Configure logging +logging.basicConfig(level=logging.DEBUG) +logger = logging.getLogger(__name__) + + +async def test_websocket_url(): + """Test WebSocket URL construction.""" + # Test multiaddr from your JS node + maddr_str = "/ip4/127.0.0.1/tcp/35391/ws/p2p/12D3KooWQh7p5xP2ppr3CrhUFsawmsKNe9jgDbacQdWCYpuGfMVN" + maddr = Multiaddr(maddr_str) + + logger.info(f"Testing multiaddr: {maddr}") + + # Parse WebSocket multiaddr + parsed = parse_websocket_multiaddr(maddr) + logger.info( + f"Parsed: is_wss={parsed.is_wss}, sni={parsed.sni}, rest_multiaddr={parsed.rest_multiaddr}" + ) + + # Construct WebSocket URL + if parsed.is_wss: + protocol = "wss" + else: + protocol = "ws" + + # Extract host and port from rest_multiaddr + host = parsed.rest_multiaddr.value_for_protocol("ip4") + port = parsed.rest_multiaddr.value_for_protocol("tcp") + + websocket_url = f"{protocol}://{host}:{port}/" + logger.info(f"WebSocket URL: {websocket_url}") + + # Test basic WebSocket connection + try: + from trio_websocket import open_websocket_url + + logger.info("Testing basic WebSocket connection...") + async with open_websocket_url(websocket_url) as ws: + logger.info("āœ… WebSocket connection successful!") + # Send a simple message + await ws.send_message(b"test") + logger.info("āœ… Message sent successfully!") + + except Exception as e: + logger.error(f"āŒ WebSocket connection failed: {e}") + import traceback + + logger.error(f"Traceback: {traceback.format_exc()}") + + +if __name__ == "__main__": + import trio + + trio.run(test_websocket_url) diff --git a/libp2p/transport/__init__.py b/libp2p/transport/__init__.py index 67ea6a740..29b3e63bd 100644 --- a/libp2p/transport/__init__.py +++ b/libp2p/transport/__init__.py @@ -10,19 +10,25 @@ from .upgrader import TransportUpgrader from libp2p.abc import ITransport -def create_transport(protocol: str, upgrader: TransportUpgrader | None = None) -> ITransport: +def create_transport(protocol: str, upgrader: TransportUpgrader | None = None, **kwargs) -> ITransport: """ Convenience function to create a transport instance. -
