2024-09-10[ruby/resolv] test_dns: Fix FD leakKasumi Hanazuki
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.

2024-08-13[ruby/resolv] test_dns: Fix failure on WindowsSorah Fukumori
(https://github.com/ruby/resolv/pull/58) test_dns: Fix failure on Windows 1. Switch to #with_udp_and_tcp helper method for EACCES retries on Windows; the given UDP socket is unnecessary though. 2. Using 127.0.0.1 should be fine, as it must give different host:port pair. 3. On Windows, 5 retries of bind(2) appears still flaky, doubling it for sure. follow-up: https://github.com/ruby/resolv/pull/50 follow-up: https://github.com/ruby/resolv/commit/6252914e95dfdf8995d8074df6cafe6f0a76c1ca https://github.com/ruby/resolv/commit/0a0d57e369
2024-08-13[ruby/resolv] Fix TCP fallback with multiple nameserversIgor Pstyga
Under the following conditions the exception `Resolv::DNS::Requester::RequestError: host/port don't match` is raised: - Multiple nameservers are configured for Resolv::DNS - A nameserver falls back from UDP to TCP - TCP request hits Resolv::DNS timeout - Resolv::DNS retries the next nameserver More details here https://bugs.ruby-lang.org/issues/8285 https://github.com/ruby/resolv/commit/7d524df80e Co-authored-by: Julian Mehnle <julian@mehnle.net>
2024-03-31[ruby/resolv] Add an explicit with_udp_and_tcp helper to test_dns.rbKJ Tsanaktsidis
This helper tries to bind UDP and TCP sockets to the same port, by retrying the bind if the randomly-assinged UDP port is already taken in TCP. This fixes a flaky test. [Bug #20403] https://github.com/ruby/resolv/commit/3d135f99d9

2023-11-24[ruby/resolv] Fix the fallback from UDP to TCP due to message truncationJeremy Evans
If truncation is detected, return immediately from decode so that the UDP connection can be retried with TCP, instead of failing to decode due to trying to decode a truncated response. Fixes [Bug #13513] https://github.com/ruby/resolv/commit/0de996dbca
2023-11-22[ruby/resolv] IPv6: update to_s method to be RFC5952 compliantJohn Bond
(https://github.com/ruby/resolv/pull/25) * IPv6: update to_s method to be RFC5952 compliant I noticed that the resolv library does not honour RFC 5952 Section 4.2.2. in relation to textural representation of ipv6 addresses: The symbol "::" MUST NOT be used to shorten just one 16-bit 0 field. For example, the representation 2001:db8:0:1:1:1:1:1 is correct, but 2001:db8::1:1:1:1:1 is not correct.

2020-11-07Remove sender/message_id pair after response received in resolvJeremy Evans
Once a response for a given DNS request has been received (which requires a matching message id), the [sender, message_id] pair should be removed from the list of valid senders. This makes it so duplicate responses from the same sender are ignored. Fixes [Bug #12838] Notes: Merged: https://github.com/ruby/ruby/pull/3536
