getaddrinfo :: ?

[Chris Morris]

I'm tinkering around with Borges on my XP box and one of the first
things it tries to do out of the chute is:

server = WEBrick::HTTPServer.new(options)
server.listen('::', 7000)

The listen method inside WEBrick is:

def listen(address, port)
res = Socket::getaddrinfo(address, port,
Socket::AF_UNSPEC, # address family
Socket::SOCK_STREAM, # socket type
0, # protocol
Socket::AI_PASSIVE) # flag

I assume '::' is shorthand for something, localhost if I had to guess
... but Googling for :: doesn't work so I've no idea where to start
looking. This is raised as an error:

c:/ruby/lib/ruby/1.8/webrick/server.rb:77:in `getaddrinfo': getaddrinfo:
no addr
ess associated with hostname. (SocketError)
from c:/ruby/lib/ruby/1.8/webrick/server.rb:77:in `listen'
from C:/ruby/lib/ruby/site_ruby/1.8/Borges/WEBrick.rb:67:in `create'
from C:/ruby/lib/ruby/site_ruby/1.8/Borges/WEBrick.rb:77:in `start'
from C:/ruby/lib/ruby/site_ruby/1.8/Borges/WEBrick.rb:88

Can anyone help me here?

I replaced the Borges/WEBrick.rb code with localhost and it gets past
getaddrinfo, but then fails on the TCPServer.new line:

def listen(address, port)
res = Socket::getaddrinfo(address, port,
Socket::AF_UNSPEC, # address family
Socket::SOCK_STREAM, # socket type
0, # protocol
Socket::AI_PASSIVE) # flag
last_error = nil
sockets = []
res.each{|ai|
begin
@logger.debug("TCPServer.new(#{ai[3]}, #{ai[1]})")
sock = TCPServer.new(ai[3], ai[1])
Utils::set_close_on_exec(sock)
sockets << sock
rescue => ex
@logger.warn("TCPServer Error: #{ex}")
last_error = ex
end
}
raise last_error if sockets.empty?
return sockets
end

with the following:

c:/ruby/lib/ruby/1.8/webrick/server.rb:91:in `listen': Unknown Error -
bind(2) (
Errno::E048)
from C:/ruby/lib/ruby/site_ruby/1.8/Borges/WEBrick.rb:67:in `create'
from C:/ruby/lib/ruby/site_ruby/1.8/Borges/WEBrick.rb:77:in `start'
from C:/ruby/lib/ruby/site_ruby/1.8/Borges/WEBrick.rb:88

I replaced the Borges/WEBrick.rb code with localhost and it gets past
getaddrinfo, but then fails on the TCPServer.new line:

I'm guessing this is older Borges code with newer WEBrick code. This is
the failing Borges code:

server = WEBrick::HTTPServer.new(options)
server.listen('127.0.0.1', 7000)
server.mount("/borges", self, options)

The HTTPServer.new call itself sets up shop on TCP port 7000, so the
following listen call is failing because the port is already in use.
Remmed out the .listen line and now we're rolling.

See alpha3, which does this the right way:
http://segment7.net/ruby-code/borges/Borges-1.0.0-alpha3.tar.gz

Oh, ha! I lied, I fixed this _after_ alpha3 (about 5 minutes after)

Here's the patch:
