Subject: [ruby-core:33813] [Ruby 1.8-Bug#3787] TCPSocket.new() fails on IPv6 connections for IPV4/IPv6 hosts

Issue #3787 has been updated by Akira Matsuda.


Oh, sorry. You're right.

In my case, while I can connect to 1200 via v4,

% ruby -d -v -rsocket -e "p TCPSocket.new('127.0.0.1', 1200)"
ruby 1.8.7 (2010-08-16 patchlevel 302) [i686-darwin10]
#<TCPSocket:0x10018a078>

it fails to connect using v6.

% ruby -d -rsocket -e "p TCPSocket.new('::1', 1200)"
Exception `Errno::ECONNREFUSED' at -e:1 - Connection refused - connect(2)
-e:1:in `initialize': Connection refused - connect(2) (Errno::ECONNREFUSED)
	from -e:1:in `new'
	from -e:1

And I'm sure '::1' stands for localhost.

% ruby -d -rsocket -e "p IPSocket.getaddress('localhost')"
"::1"

Should I post another ticket for this?
