EventMachine Unleashes the Mind

Question

I create a program with EventMachine, and sometimes clients on weak Internet will run unbind in our program. I was wondering how I can determine why the unbind function is running, and if I can do something to help these weak clients.

Answer 1

Unbind is called when the connection is terminated for any reason, usually you need to connect to the server.

class MyConnection < EM::Connection def initialize(host, port) @host, @port = host, port @retry = 0 end def self.connect(host, port, timeout) EM.connect(host, port, self, host, port) end def connection_completed @retry = 0 end def unbind if @retry < 3 EM.add_timer(1){ @retry +=1 && reconnect(@host, @port) } else fail "Can't reconnect" end end end 

Answer 2

you can also define unbind with the "reason" parameter:

 def unbind(reason=nil) end
