The reference server implementation of Socket.IO runs on Node.js and was developed by LearnBoost. There are now server implementations Only ~3 lines of code are required to tie-in gevent-socketio in your framework. Note: you need to use the gevent python WSGI server to use gevent- socketio. Namespaces: since you mostly have one websocket/socket

证，健壮性无比强大。 背景 背景 最近在做一个基于 Websocket 的长连中间件，服务端使用实现了 Socket.IO 协议（基于WebSocket协 议，提供长轮询降级能力） 的 netty-socketio  框架，该框架为 Netty 实现，鉴于本人对 Netty 比较 熟，并且对比同样实现了 Socket.IO 协议的其他框架，Netty 的口碑都要更好一些，因此选择这个框架作 为底层核心。 的内存，随着Bug被触发，内存也没有释放。问题缩小之后，接下来开始“撸源码”，捉虫！ 阶段7：线下排查 阶段7：线下排查 接下来，我们将本地服务重启，开始完整的线下排查过程。同时将目光定位到 netty-socketio 这个框架 的 Disconnect 事件（客户端WebSocket连接关闭时会调用到这里），基本上可以确定，在 Disconnect 事件前后申请的内存并没有释放。 在使用 idea debug

返回一个根据文件对象进行更新的摘要对象。 fileobj 必须是一个以二进制模式打开用于读取的文件型对象。它接受来自内置open(), BytesIO 实例, socket.socket.makefile() 创建的 SocketIO 及其他类似的文件对象。此函数也可能绕过 Python 的并直接使用来自fileno() 的文件描述符。在此函数返回或引发异常之后必须假定 fileobj 已处于未知状态。应当由调用方来负责关闭
