Yukon test fails on Windows 2019 runner with npcap pre-installed. #401

Closed clyde-johnston closed 1 year ago

clyde-johnston commented 1 year ago

During the pytest, the app tries to open a udp socket and create a multicast group on the loopback address using WinSock. This stackoverflow may give a clue how to fix it. It suggests not terminating the program in order to keep the socket open. The WinSock error code is [WSAEADDRNOTAVAIL].

The key error line is:

.nox\pytest\Lib\site-packages\pycyphal\transport\udp_ip_v4.py:127: in make_input_socket 359 raise InvalidMediaConfigurationError( 360 E pycyphal.transport._error.InvalidMediaConfigurationError: Could not register multicast group membership 239.0.29.85 via 127.0.0.0 using <socket.socket [closed] fd=-1, family=2, type=2, proto=17> [WSAEADDRNOTAVAIL]

I was able to reproduce this on a PC (according to Yukon with no npcap installed) in a non-test setup just now:

however the Npcap installer says this: image After closing Yukon, Npcap is able to install With Npcap installed, I can reproduce the problem:

Now when I change 127.0.0.0 addresses in Yukon to 127.0.0.1, then the problem disappears.

The tests pass on a 4.8GHz processor with 32GB of RAM:
