ruby-on-rails-4 - 对 Firebase 的快速多次调用使 Rails 崩溃

Question

我的 Controller 在某些点击时将数据推送到 Firebase。

class FirebaseController < ApplicationController

    Firebase.base_uri = "https://firebaseProject.Firebaseio.com/"  

    def call_to_firebase

        Firebase.push("firebase_channel", "firebase_data".to_json)

        respond_to do |format|
        format.json { render nothing: true, :status => 204 }
        end
    end
end

如果快速连续调用此 Controller (通过单击调用)，我的 Puma 服务器会立即崩溃。

我正在使用 Rails 4.0.0彪马 2.6.0 ruby 2.0.0

Abort trap: 6

快速是指每秒点击一次。对于速度较慢的点击(例如每 2 秒点击 1 次)，这种情况不会发生。

在循环中从 irb 推送到 firebase 不会导致此错误。

提前致谢，干杯!

您使用的是 firebase-ruby gem 吗？我今天提交了针对此问题的错误修复。您可以像这样通过重写 gem 中有问题的方法来自己对其进行热修补:

模块 Firebase

类请求

def process(method, path, body=nil, query_options={})
  request = Typhoeus::Request.new(build_url(path),
                                  :body => body,
                                  :method => method,
                                  :params => query_options)
  response = request.run
  Firebase::Response.new(response)
end

结束结束

或者等待拉取请求被接受。问题在于 gem 对 Typheous' Hydra 的使用。
