apn_sender failing to start resque worker for Apple Push Notifications

Question

I am trying to use the apn_sender gem to send Apple Push Notifications. I have followed the instructions at the github page as well as here .

My redis worker starts successfully, and I am (seemingly) able to successfully start a resque worker (and verify its running with the list command) having followed this with this command:

resque:work QUEUE='*'

However, when I try to start the app_sender with

script/apn_sender --environment=production --verbose start

I get the following error:

I, [2013-06-03T16:14:17.848632 #15074]  INFO -- : 2013-06-03 16:14:17 -0400: Running before_first_fork hook

And, my script/apn_sender looks like:

#!/usr/bin/env ruby

# Daemons sets pwd to /, so we have to explicitly set RAILS_ROOT
RAILS_ROOT =File.expand_path(File.join(File.dirname(__FILE__),'..'))

require 'rubygems'
require 'apn'
require 'apn/sender_daemon'

APN::SenderDaemon.new(ARGV).daemonize

Any help would be appreciated!

Answer 1

I am pretty much sure the issue in here is the version of resque. I will double check, but as far as I tested apn_sender works with resque 1.19.0 and nothing over that. The reason in here is some monkey patches on resque gem. After double checking the correct version of resque I will push a update to the gemspec file so nobody will get this anymore. Also in version 2.0(master) we are not monkey patching resque anymore, and wont even be a forced dependency.

Short fix for you, force the resque version to use 1.19.0.
