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...
Node.js is built uponlibuv, a cross-platform library that abstracts apis/syscalls for asynchronous (non-blocking) input/output provided by the supported OSes (Unix, OS X and Windows at least). Asynchronous IO In this programming model open/read/write operation on devices and resources (sockets...

如你所见,在non-blocking配置中使用了"org.apache.coyote.http11.Http11NioProtocol"替代了"HTTP/1.1"。通过此配置调整Tomcat就会以non-blocking的模式运行。 然后,我们创建两个servlets。第一个LoginServlet用于处理client的登陆并订阅消息主题(channel),示例如下: packagech.maxant.blog.nio.servlet3;importjava.io.I...

Anode.jsbinding to MariaDB's non-blocking (MySQL-compatible) client library. This binding is different from a vanilla libmysqlclient binding in that it uses the non-blocking functions available in MariaDB's client library. As a result, this binding doesnotuse multiple threads to achieve non-blo...

@nodejs/documentation does anyone know if there's a test CI that we could run for this? To increase confidence that the bundle published is the one intended, we could do a checksum comparison. This would ensure that the bundle in doc/api_assets is the one that gets client-side executed...
在package.json 里增加resolutions来覆盖版本定义 1 2 3 "resolutions":{ "stylus":"^0.54.8" } JSON 然后重新yarn install一下就好了。 至此hexo 就可以和 node.js 14 开始愉快的旅程了~ 参考:
Fiddler will show a tab "WebSocket" and we can easily see the full content of packets in Websocket like this: But how to capture packet which doesn't come from browser, but from other runtime (for example Node.js)? I tried npm config first, npm config set proxy...
