Tornado Workers There’s also a Tornado worker class. It can be used to write applications using the Tornado framework. Although the Tornado workers are capable of serving a WSGI application, this is not a recommended configuration. Choosing a Worker Type The default synchronous workers assume that...
SIGHUP: Reload the configuration, start the new worker processes with a new configuration and gracefully shutdown older workers. SIGUP对应的信号处理函数是Arbiter.reload。简化后的核心代码如下: 1 def reload(self): 2 old_address = self.cfg.address 3 4 # reload conf,重新加载配置 5 self.app.rel...
This resource bound assumption is why we require a buffering proxy in front of a default configuration Gunicorn. If you exposed synchronous workers to the internet, a DOS attack would be trivial by creating a load that trickles data to the servers. For the curious,Slowlorisis an example of t...
1. Gunicorn项目的入口文件分析 从前面分析中,不难看出Gunicorn项目的入口文件是【/gunicorn/app/wsgiapp.py】,该文件及其相关文件内容如下(无关紧要的信息,省略掉)。 ### gunicorn/app/wsgiapp.py ###classWSGIApplication(Application):# some code are omitteddefrun():fromgunicorn.app.wsgiappimportWSGIAppli...

最近使用Gunicorn+Flask部署了一套服务,顺便研究下Gunicorn的源码,看看Python 的Prefork模型是如何实现的。具体Gunicorn的用法可以看官方文档,本文直接从源码开始入手。 官方主页:Gunicorn 官方文档:Gunicorn Document 源码版本:gunicorn (version 19.9.0) 源码目录结构: ...
@evgeni has done some testing and found that adding the --preload flag to the gunicorn execution command line for the pulpcore-content service reduces the memory overhead required by several hundred megabytes, because it is able to share more memory pages, and several copies of the pulpcore-con...
