Question

我按照确切的步骤从rapns迁移到rpush。 https://github.com/rpush/rpush/wiki/Moving-from-Rapns-to-Rpush

一切似乎都没问题所以我决定在rails控制台中运行这个例子。

n = Rpush::Apns::Notification.new
n.app = Rpush::Apns::App.find_by_name("ios_app")
n.device_token = "..." # 64-character hex string
n.alert = "hi mom!"
n.save!
Rpush.push

我在执行rpush / daemon / apprunner.rb时得到这个堆栈：18

@runners[app_id].enqueue(group) if @runners[app_id]

更准确地说是app_runner.rb：122

batch_size = (notifications.size / num_dispatcher_loops.to_f).ceil

我有与https://github.com/rpush/rpush/wiki/Configuration

相同的配置文件

更新1 我在app_runner.rb中添加了一些日志：

def enqueue(notifications)
    ap notifications
    ap service
    ap num_dispatcher_loops
    if service.batch_deliveries?
      batch_size = (notifications.size / num_dispatcher_loops.to_f).ceil
      notifications.in_groups_of(batch_size, false).each do |batch_notifications|
        batch = Batch.new(batch_notifications)
        queue.push(QueuePayload.new(batch))
      end
    else
      batch = Batch.new(notifications)
      notifications.each do |notification|
        queue.push(QueuePayload.new(batch, notification))
        reflect(:notification_enqueued, notification)
      end
    end
  end

以下是日志：

Answer 1

在红宝石中除以零会给你无限：

irb(main):002:0> 4 / 0.to_f
=> Infinity

在这种情况下，您的调试显示num_dispatcher_loops为0.围绕代码（rpush/daemon/app_runner.rb），这是@dispatcher_loops的长度，它被初始化为空但填充在{{ 1}}。我的猜测是后者没有被调用。它应该在#start_dispatchers中发生。追溯（仅在代码库中搜索）会导致回到.start_app和Daemon以及Embed上的顶级方法。 Synchronizer可能实际上并未正常运行。

您使用什么方法（来自README中的“运行Rpush”）来运行rpush？
