It is common for production and non-production (development, test) code to connect to different hosts which can produce errors due to wrong configuration. This change will make the ruby stdlib code more consistent as other methods already provide useful error information. Some examples: host = 'nonexistent.example.com'; port = 80 Resolv.getaddress host # => Resolv::ResolvError: no address for nonexistent.example.com Socket.getservbyname host # => SocketError: no such service nonexistent.example.com/tcp Net::HTTP.get Struct.new(:hostname, :port, :scheme).new(host, port, 'http') # => SocketError: Failed to open TCP connection to nonexistent.example.com:80 (getaddrinfo: Name or service not known) If this issue will be resolved, please add any useful information to the error message in addition to the host. -- https://bugs.ruby-lang.org/ Unsubscribe:
