Problems with netio and public_api tests when running without Internet #567

Open gavv opened 9 months ago

gavv commented 9 months ago

When network interfaces are up, but there is no Internet connection, one test in roc-test-netio hangs for a while. However after a while all tests pass.

When all network interfaces, except loopback, are down, some tests in roc-test-netio and roc-test-public-api fail:

(tested on Linux)

We need to investigate the reason and if possible, make tests passing without delays when there is no Internet.

Note: use -v option to enable logs in tests.

If no network interface is up except localhost on Ubuntu 20.04, the test udp_ports::add_multicast_receiver fails:
