I see some CI failures in my forked repo, which seem related to this change. I realized that this patch is not good as it alters the meaning of the test case (the TCP requester now experiences early shutdown instead of timeout). I'll revise the patch. |
The listening TCP socket is closed by `with_udp_and_tcp` helper, but the connected socket is leaking. ``` Leaked file descriptor: TestResolvDNS#test_multiple_servers_with_timeout_and_truncated_tcp_fallback: 12 : #<TCPSocket:fd 12, AF_INET, 127.0.0.1, 50888> COMMAND PID USER FD TYPE DEVICE SIZE/OFF NODE NAME ruby 3248055 chkbuild 12u IPv4 112546322 0t0 TCP localhost:50888->localhost:40112 (CLOSE_WAIT) ``` For the purpose of the test case to simulate a timeout over TCP transport, we have to delay closing this socket until the end the test case. Fixup: ruby#50
