A quick script to selectively remove Failed Jobs from Resque 1.x

Copy to snippet below and paste it in a rails console

def delete_if
 redis = Resque.redis

 (0...Resque::Failure.count).each do |i|
 string = redis.lindex(:failed, i)
 break if string.nil?

 job = Resque.decode(string)
 remove = yield job
 next unless remove

 redis.lrem(:failed, 1, string)
 redo
 end
end

To selectively delete a subset of failed jobs, say delete all push notification jobs that have failed because of http errors

delete_if do |job|
 job['payload']['class'] == 'SendPushNotification' &&
 job['exception'] == 'Pusher::HTTPError'
end
