Eventmachine talk - Dec 2007 - connection_completed never called after popen

Hi Francis,

Is it possible to make EventMachine call the connection_completed method
after a successful popen?  I''m setting some variables in the block
passed to
popen but they''re not yet available to post_init at the time the latter
function is called.

Best regards,

--Michael

No problem with this request in principle but can you give a code sample to
show exactly what you''re trying to do? I''m not seeing the
timing problem,
and I''d like a unit test in any case. Thanks.

Sure, here''s an abstract test case:

class Executor < EventMachine::Connection
    attr_accessor :command, :param

    def self.popen(command, param)
        conn = EventMachine::popen(command, self) do |conn|
            conn.command = command
            conn.param = param
        end
    end

    def post_init
         puts "#{@param}" # Race condition: @param not defined yet
->
exception thrown
    end
end

Best regards,
