web2py

I have a thread doing a lot of CPU-intensive processing, which seems to be blocking out other threads. How do I limit it? This is for web2py specifically, but a general solution would be fine. I actually just ended up diving into this issue not long ago, you wont be able to change the thread priority but there are ways around this. To give you a bit of background on the problem, in the cPython implementation CPU bound threads can cause other threads to starve because of the way the Global Interpreter Lock or GIL is released and acquired. Oddly enough this problem is made worse in a multicore

I'm going to develop a small web application on Gae with a registration section, login\logout and stuff like that. Since Google app Engine does not support session out of the box and I don't want to restrict access using google Accounts, I am forced to pick a Framework that offers this kind of facilities. My choices are: Web2py Djangoappengine Webpy Reading its book, Web2py seems to offer session object and has a good access control, offering an Auth class that implements Role-Based Access Control . I don't know Djangoappengine yet but I suppose it offers Django Auth . Webpy works on appengine

I'm seeing weird behavior on this code: images = dict(cover=[],second_row=[],additional_rows=[]) for pic in pictures: if len(images['cover']) == 0: images['cover'] = pic.path_thumb_l elif len(images['second_row']) < 3: images['second_row'].append(pic.path_thumb_m) else: images['additional_rows'].append(pic.path_thumb_s) My web2py app gives me this error: if len(images['cover']) == 0: TypeError: object of type 'NoneType' has no len() I can't figure out what's wrong in this. Maybe some scope issue? You assign something new to images['cover'] : images['cover'] = pic.path_thumb_l where pic.path

I would like to learn the benefits of using HTML helpers in web2py instead of plain HTML markup elements. As an example, I read the following HTML markup builder code in a web2py application (reddish): {{=A(IMG(_src=URL(r=request,c='static',f='up.png')),

The following code works: import pyodbc cnxn = pyodbc.connect('DRIVER={SQL Server};SERVER=localhost;DATABASE=testDB;UID=testUser;PWD=password1') cursor = cnxn.cursor() cursor.execute("select * from tbUsers") rows = cursor.fetchall() for row in

本文主要是对Web2py框架的介绍和安装使用。 一、 介绍 全栈式Web框架；Web2py是 Google 在 web.py 基础上二次开发而来的，兼容 Google App Engine 。是一个为Python语言提供的全功能Web应用框架，旨在敏捷快速的开发Web应用，具有快速、安全以及可移植的数据库驱动的应用。 官方网站为: http://www.web2py.com/ 二、 安装和使用 安装网站: http://www.web2py.com/ 我本地是Windows所以就算点击红色标记处 通常会以ZIP包的形式下载，你可以选择解压在那个目录下。 1.使用 很简单就是运行web2py.exe会弹出这个 2.你可以自定义端口和输入对应的密码即可，然后点击start server，默认IE浏览器打开，出现如下界面：
