Blocking calls with Gevent and WSGI

由 安稳与你 提交于 2019-12-22 11:11:48
问题 I've just started working with coroutines and have read up on gevent and greenlets. For a test I served this code through gevents pywsgi module: from gevent.pywsgi import WSGIServer import gevent def hello_world(env, start_response): gevent.sleep(5) start_response('200 OK', [('Content-Type', 'text/html')]) return ["<b>hello world</b>"] print 'Serving on 8088...' WSGIServer(('127.0.0.1', 8888), hello_world).serve_forever() I expected a result where every request would get a 5 second delay

Flask WSGI application hangs when import nltk

由 随声附和 提交于 2019-12-22 05:01:14
问题 I followed the instructions here to create a onefile flask-app deployed to apache2 with mod-wsgi on ubuntu. That all works fine when using the original flask app. However, when adding import nltk to the flask app apache hangs (no 500). I use python 2.7 and nltk 2.0.4 Others seem to have had similar problems with other packages. Setting WSGIApplicationGroup %{GLOBAL} in the VirtualHost configuration seemed to have helped. However, I still get the same behavior. Did anybody run into the same

网关协议

【推荐】2019 Java 开发者跳槽指南.pdf(吐血整理) >>> CGI CGI即通用网关接口(Common Gateway Interface)，是外部应用程序（CGI程序）与Web服务器之间的接口标准，是在CGI程序和Web服务器之间传递信息的规程。CGI规范允许Web服务器执行外部程序，并将它们的输出发送给Web浏览器，CGI将Web的一组简单的静态超媒体文档变成一个完整的新的交互式媒体。通俗的讲CGI就像是一座桥，把网页和WEB服务器中的执行程序连接起来，它把HTML接收的指令传递给服务器的执行程序，再把服务器执行程序的结果返还给HTML页。CGI 的跨平台性能极佳，几乎可以在任何操作系统上实现。 CGI方式在遇到连接请求（用户请求）先要创建cgi的子进程，激活一个CGI进程，然后处理请求，处理完后结束这个子进程。这就是fork-and-execute模式。所以用cgi方式的服务器有多少连接请求就会有多少cgi子进程，子进程反复加载是cgi性能低下的主要原因。当用户请求数量非常多时，会大量挤占系统的资源如内存，CPU时间等，造成效能低下。 CGI脚本工作流程： 浏览器通过HTML表单或超链接请求指向一个CGI应用程序的URL。 服务器收发到请求。 服务器执行所指定的CGI应用程序。 CGI应用程序执行所需要的操作，通常是基于浏览者输入的内容。

Error: readv() failed (104: Connection reset by peer) while reading upstream

问题 I have facebook apps with flask with nginx and uwsgi. When it receive POST from facebook, it always has error: readv() failed (104: Connection reset by peer) while reading upstream But when I access my apps directly (with GET method), it ran smoothly. What I've done: Limit @app.route with POST method only - doesn't work. Add limit in wsgi: uwsgi_buffer_size (in case request from facebook is big), and uwsgi_harakiri (in case uwsgi provide timeout before finish it request) - doesn't work. I

Python Selector (URL routing library), experience/opinions?

由 匆匆过客 提交于 2019-12-21 09:38:31
问题 Does anyone have opinions about or experience with Python Selector? It looks great, but I'm a bit put off by its "Alpha" status on pypi and lack of unit tests. I mostly like that its simple, self contained, and pure WSGI. All other url routers I've found assume I'm using django, or pylons, or paste, or pull in lots of other dependencies, or just don't let me create a simple mapping of url patterns to wsgi apps. Really, all I want to do is: mapper.add("/regex/{to}/{resource}", my_wsgi_app)

问题 I'm currently on shared hosting plan with dreamhost and have installed Django as per http://wiki.dreamhost.com/Django . However, I also have a wordpress blog that I wish to keep running in a subdirectory, i.e, site.com/blog. Is it possible to do this. Installing Django results in a passenger_wsgi.py file in the Django root directory which redirects all the requests to django if i try to go to my blog i get an error since obviously it's not in url.py. Is it possible to somehow serve the

How to get apache to serve static files on Flask webapp

由 两盒软妹~` 提交于 2019-12-21 05:06:42
问题 I'm getting a 500 internal error while trying to get Apache to serve my static files. The application will be locally hosted (not www facing). There will be no DNS to resolve a 'www.domain.com' name. I want to be able to access the application by entering the IP address of the server when I'm on that network. This is my httpd.conf file (I'm on RHEL): <Directory /var/www/testapp> Order allow,deny Allow from all </Directory> WSGIScriptAlias / /var/www/testapp/service.wsgi If I change the

轻量级django阅读笔记：最小的django应用

【推荐】2019 Java 开发者跳槽指南.pdf(吐血整理) >>> Intro 找不到工作十分难受，在家看书，恰巧翻到这本《轻量级 Django》，看起来还蛮有意思的，做个读书笔记。 1. 最小的 Django App Django 是个重量级框架，所谓最小指的是写最少的代码，理解一个 Django App 的最小组成元素。 作为开场，先创建一个 app.py 文件，作为整个 Django App 存储的地方。 1.1 django.conf.settings 书中使用 django.core.management.execute_from_command_line 作为启动 Django app 的手段。 execute_from_command_line ，就是通过 django startproject 的方式创建的 manage.py 内的主要内容，这种方式启动必须要配置 settings 才行。 在一个常规方式创建的 Django App 中， settings.py 是一个独立的 python 模块， Django 通过 DJANGO_SETTINGS_MODULE 这个环境变量来确定配置信息存储位置。 但是换一种方式， django.conf.settings.configure() 可以手动完成配置。 看代码。 from django.conf import
