Why is `node.js` dying when called from inside python/uwsgi?

问题 From the shell this python code which start and communicates with a node.js process works fine: > from subprocess import * > js = "(function(m) { console.log(m) })('hello world')" > (out,err) = Popen(["node"], stdin=PIPE, stdout=PIPE, stderr=PIPE, shell=False).communicate(js) > out "hello world\n" But when I run the same code from within uwsgi I instead get this in err : 'FATAL ERROR: v8::Context::New() V8 is no longer usable\n' Any insights from either the wsgi community or the node.js

Django 的认识，面试题 1. 对Django的认识？ #1.Django是走大而全的方向，它最出名的是其全自动化的管理后台：只需要使用起ORM，做简单的对象定义，它就能自动生成数据库结构、以及全功能的管理后台。 #2.Django内置的ORM跟框架内的其他模块耦合程度高。 #应用程序必须使用Django内置的ORM，否则就不能享受到框架内提供的种种基于其ORM的便利； #理论上可以切换掉其ORM模块，但这就相当于要把装修完毕的房子拆除重新装修，倒不如一开始就去毛胚房做全新的装修。 #3.Django的卖点是超高的开发效率，其性能扩展有限；采用Django的项目，在流量达到一定规模后，都需要对其进行重构，才能满足性能的要求。 #4.Django适用的是中小型的网站，或者是作为大型网站快速实现产品雏形的工具。 #5.Django模板的设计哲学是彻底的将代码、样式分离； Django从根本上杜绝在模板中进行编码、处理数据的可能。 2. Django 、Flask、Tornado的对比 #1.Django走的是大而全的方向,开发效率高。它的MTV框架,自带的ORM,admin后台管理,自带的sqlite数据库和开发测试用的服务器 #给开发者提高了超高的开发效率 #2.Flask是轻量级的框架,自由,灵活,可扩展性很强,核心基于Werkzeug WSGI工具和jinja2模板引擎 #3

问题 While hitting a REST resource ( my_resource ) in Python, the uWSGI server is throwing the following error in its log: SIGPIPE: writing to a closed pipe/socket/fd (probably the client disconnected) on request my_resource (ip <my_ip>) !!! uwsgi_response_write_body_do(): Broken pipe [core/writer.c line 164] IOError: write error It seems to be related to a timeout (the client disconnected before the request could finish processing).
