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.

Introduced `get_wildcard_address` function for explicit wildcard binding. - Updated examples to use `get_available_interfaces` and `get_optimal_binding_address` for address selection. - Ensured consistent usage of the new address paradigm across all example files. - Added tests to verify the implementation of the new address paradigm and wildcard feature. --- examples/advanced/network_discover.py | 9 +- examples/bootstrap/bootstrap.py | 12 +- examples/chat/chat.py | 13 +- examples/doc-examples/example_multiplexer.py | 13 +- examples/doc-examples/example_net_stream.py | 14 +- examples/doc-examples/example_running.py | 13 +- examples/doc-examples/example_transport.py | 13 +- examples/echo/echo.py | 7 +- examples/identify/identify.py | 13 +- examples/kademlia/kademlia.py | 14 +- examples/ping/ping.py | 13 +- examples/pubsub/pubsub.py | 14 +- libp2p/utils/address_validation.py | 64 ++++----- tests/examples/test_examples_bind_address.py | 105 +++++++------- tests/utils/test_default_bind_address.py | 144 +++++++++++-------- 15 files changed, 280 insertions(+), 181 deletions(-) diff --git a/examples/advanced/network_discover.py b/examples/advanced/network_discover.py index 71edd209..13f7d03a 100644 --- a/examples/advanced/network_discover.py +++ b/examples/advanced/network_discover.py @@ -14,6 +14,7 @@ try: expand_wildcard_address, get_available_interfaces, get_optimal_binding_address, + get_wildcard_address, ) except ImportError: # Fallbacks if utilities are missing @@ -29,6 +30,9 @@ except ImportError: def get_optimal_binding_address(port: int, protocol: str = "tcp"): return Multiaddr(f"/ip4/127.0.0.1/{protocol}/{port}") + def get_wildcard_address(port: int, protocol: str = "tcp"): + return Multiaddr(f"/ip4/0.0.0.0/{protocol}/{port}") + def main() -> None: port = 8080 @@ -37,7 +41,10 @@ def main() -> None: for a in interfaces: print(f" -
