[ruby-core:116557] [Ruby master Bug#20172] Socket.addrinfo failing randomly

Issue #20172 has been updated by ioquatix (Samuel Williams). For reference, I had a user report a similar issue due to `Addrinfo#ip_address`: https://github.com/socketry/falcon/issues/217 ---------------------------------------- Bug #20172: Socket.addrinfo failing randomly https://bugs.ruby-lang.org/issues/20172#change-106574 * Author: mwaldvogel (Michael Waldvogel) * Status: Closed * Priority: Normal * ruby -v: ruby 3.3.0 (2023-12-25 revision 5124f9ac75) [x86_64-linux] * Backport: 3.0: DONTNEED, 3.1: DONTNEED, 3.2: DONTNEED, 3.3: REQUIRED ---------------------------------------- I've recently updated one of my linux systems (Gentoo) to glibc 2.38 (that was the only change). After the update most of the time the below error happens. Among other things this breaks rubygems for me. I've reinstalled ruby 3.2.2 with rvm and didn't encounter the issue. The issue however remained even after reinstalling ruby 3.3.0 and even with ruby master. Since this goes back to getaddrinfo (which is working without any issues outside of ruby) and there seems to be only one bigger change to stdlib socket, I'm assuming the problem was introduced with https://bugs.ruby-lang.org/issues/19965 ``` 3.3.0 :001 > require 'socket' => true 3.3.0 :002 > Socket.getaddrinfo('rubygems.org', 443) (irb):2:in `getaddrinfo': getaddrinfo: Temporary failure in name resolution (Socket::ResolutionError) from (irb):2:in `<main>' from <internal:kernel>:187:in `loop' from /usr/local/rvm/rubies/ruby-3.3.0/lib/ruby/gems/3.3.0/gems/irb-1.11.0/exe/irb:9:in `<top (required)>' from /usr/local/rvm/rubies/ruby-3.3.0/bin/irb:25:in `load' from /usr/local/rvm/rubies/ruby-3.3.0/bin/irb:25:in `<main>' 3.3.0 :003 > Socket.getaddrinfo('rubygems.org', 443) (irb):3:in `getaddrinfo': getaddrinfo: Temporary failure in name resolution (Socket::ResolutionError) from (irb):3:in `<main>' from <internal:kernel>:187:in `loop' from /usr/local/rvm/rubies/ruby-3.3.0/lib/ruby/gems/3.3.0/gems/irb-1.11.0/exe/irb:9:in `<top (required)>' from /usr/local/rvm/rubies/ruby-3.3.0/bin/irb:25:in `load' from /usr/local/rvm/rubies/ruby-3.3.0/bin/irb:25:in `<main>' 3.3.0 :004 > Socket.getaddrinfo('rubygems.org', 443) => [["AF_INET", 443, "151.101.193.227", "151.101.193.227", 2, 1, 6], ["AF_INET", 443, "151.101.193.227", "151.101.193.227", 2, 2, 17], ["AF_INET", 443, "151.101.193.227", "151.101.193.227", 2, 3, 0], ...
