Subject: [ruby-talk:15628] more fun with TCPServer

Hello again :)

I think there must be some kind of strange threading voodoo going on - I
have this working, in a way.  What happens with this is that after multiple
people connect, eventually the threads of all but the last one seem to stop
running after typing a few lines, seemingly stalling on the
user.socket.gets.  The last user to connect can continue to type, and
everything is still echoed out to all the other users, but nothing they type
ever echoes to anyone.  Checking netstat, the buffers on the other
connections continue to grow as other users type, but gets never seems to
happen.  Is this a problem with gets or threading?

Thanks,
David

users = []
port = 4242
server = TCPServer.new('localhost', port)

while (session = server.accept)
    users << User.new(session)
      users.last.thread = Thread.new(users.last) { |user|
        user.linenum = users.length
        user.address = user.socket.addr
        puts "connected: #{user.to_s}"
        until user.socket.eof
          input = user.socket.gets
          puts input
          users.each {|user| user.write(input) }
        end
        users.delete_at(user.linenum - 1)
        user.socket.close
      }
end
