阻塞(Blocking) 阻塞指的是一部分Node.js代码需要等到一些非Node.js代码执行完成之后才能继续执行。这是因为当阻塞发生时,Event Loop无法继续执行。 对于Node.js来说,由于CPU密集的操作导致代码性能很差时,不能称为阻塞。当需要等待非Node.js代码执行时,才能称为阻塞。Node.js中依赖于libuv的同步方法(以Sync结尾)导...

Luaw - Lua meets Node.js Luaw stands for "Lua web server". It also matches abbreviation for an air traffic controller command "Line Up And Wait" that closely resembles the way it handles multiple requests using event loop :) Luaw is an event driven, non blocking IO based HTTP applicatio...
现在通过对Comet的了解,我意识到在web应用中,non-blocking服务确实有非常棒的使用场景:给client推送数据,例如在股票网站上给client推送最新的股票价格。这种场景可通过轮询(poll)方案解决,而Comet使用长轮询(long-polling)或者更好的方案:服务端数据推送(full on push)。这有篇不错的入门指引,Comet的的智慧在于,当cli...
Event-driven, non-blocking I/O with PHP.ReactPHP is a low-level library for event-driven programming in PHP. At its core is an event loop, on top of which it provides low-level utilities, such as: Streams abstraction, async DNS resolver, network client/server, HTTP client/server and ...
