Eventmachine talk - Feb 2008 - don''t call receive_data ?

Is there a way to tell eventmachine to not call receive_data for
certain requests?

here is my workaround using @skip:

BL = {''123.123.123.123'' => true}  # blacklist
module Tester
  include Socket::Constants

  def post_init  # do rate limiting here
    port, ip = Socket.unpack_sockaddr_in(self.get_peername)
    if BL[ip]  # blacklisted, shut down connection
      send_data "denied\n"
      close_connection_after_writing
      @skip = true
      return
    end
  end

  def receive_data(data)
    return if @skip  # is there a way cause receive_data to no tbe called?
    send_data "thanks!\n"
    close_connection_after_writing
  end
end
EventMachine::run {
  EventMachine::start_server("127.0.0.1", 4300, Tester)
}

I''d like to get rid of that @skip variable and check if possible.

thanks,

I think when the connection is closed in #post_init, further #sysreads will
fail, and send a ConnectionUnbound to the event callback, therefore
removing the connection.

I''m not sure if it''s the cleanest way and I didn''t
test it on many
different machines, but trying out your snippet, it works without the @skip
parts:
>   def post_init  # do rate limiting here
>     port, ip = Socket.unpack_sockaddr_in(self.get_peername)
>     if ip == "192.168.11.9"
>       send_data "denied\n"
>       close_connection_after_writing
>     end
>   end
>
>   def receive_data(data)
>     send_data "thanks!\n"
>     close_connection_after_writing
>   end
> end

And returns "denied\n" without "thanks!\n" as expected.
