Feature #13677: Add more details to error "Name or service not known (SocketError)" - Ruby master - Ruby Issue Tracking System

In general I agree that error messages should be as useful as possible.

(By the way, I think if you indent ruby code here in the bug tracker with four space tokens
on the left side aka ' ', colouring will be enabled. Would make it easier for others to
read it... let me try it).

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)

Edit: Oops not quite ... only indents to the left side as blockquote or so...

    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)
