ruby @1.8.6-p114 patch to get Ruby's Socket classes to work with getaddrinfo under 10.5.3

[aguynamedryan+macports@…]

Kurt Schrader posted in ​this thread, that after upgrading to Mac OS X 10.5.3 some calls to DRb fail with:

/opt/local/lib/ruby/1.8/drb/drb.rb:865:in `initialize': getaddrinfo:
nodename nor servname provided, or not known (SocketError)
from /opt/local/lib/ruby/1.8/drb/drb.rb:865:in `open'
from /opt/local/lib/ruby/1.8/drb/drb.rb:865:in `open_server'

It appears that Ruby's calls to getaddrinfo which pass "0" for the servname argument are now returning EAI_NONAME instead of 0, which causes ruby to raise a SocketError

Andy Keep discovered that feeding nil in place of of "0" for the service number works:

irb(main):001:0> require 'socket'
=> true
irb(main):011:0> Socket.getaddrinfo(Socket.gethostname, 0, 
Socket::AF_INET, Socket::SOCK_STREAM, nil, Socket::AI_CANONNAME)
SocketError: getaddrinfo: nodename nor servname provided, or not known
  from (irb):11:in `getaddrinfo'
  from (irb):11
  from :0
irb(main):012:0> Socket.getaddrinfo(Socket.gethostname, nil, 
Socket::AF_INET, Socket::SOCK_STREAM, nil, Socket::AI_CANONNAME)
=> [["AF_INET", 0, "192.168.1.95", "192.168.1.95", 2, 1, 6]]

I have discovered that TCPServer.open('localhost', 0) also fails under 10.5.3 both in MacPorts and in the Ruby installation that ships with Mac OS X Leopard.

I have very little socket programming experience, but I have made a patch that changes Socket's servname argument of "0" and replaces it with NULL before it is passed to getaddrinfo.

I have no idea what unintended effects this might cause, but it seems to have cleared up my problems with DRb and TCPServer for the time being.

Adds a few test cases which expose some of the breakage caused by 10.5.3's change to getaddrinfo

[aguynamedryan+macports@…]

Adds a some code that replaces a servname of "0" with NULL before calling getaddrinfo
