PowerDNS

The PowerDNS server daemon is a versatile nameserver which supports a large number of backends. These backends can either be plain zonefiles or be more dynamic in nature. Additionally, through use of clever programming and caching techniques, PowerDNS offers very high domain resolution performance. ... [More] Prime examples of backends include relational databases, but also (geographical) loadbalancing and failover algorithms. The PowerDNS recursor daemon which is also part of the PowerDNS compilation is a dedicated high performance recursive (aka caching-only) Nameserver that already powers some larger broadband ISPs and as of late learned to embed Lua Scripts making it possible to manipulate DNS Answers from within those Scripts.

Tornado Web Server (tornadoweb)

Tornado is an open source version of the scalable, non-blocking web server and tools that power FriendFeed. The FriendFeed application is written using a web framework that looks a bit like web.py or Google's webapp, but with additional tools and optimizations to take advantage of the underlying non-blocking infrastructure.

Eventlet

Eventlet is a networking library written in Python. It achieves high scalability by using non-blocking io while at the same time retaining high programmer usability by using coroutines to make the non-blocking io operations appear blocking at the source code level.

cogen

Coroutines in python using enhanced generators from python 2.5

gevent

gevent is a coroutine-based Python networking library that uses greenlet to provide a high-level synchronous API on top of libevent event loop. Features include: convenient API around greenlets familiar synchronization primitives socket module that cooperates WSGI server on top of ... [More] libevent-http DNS requests done through libevent-dns monkey patching utility to get pure Python modules to cooperate [Less]

lua-handlers

Provides a set of async. callback based handlers for working with raw TCP/UDP socket, ZeroMQ sockets, or HTTP requests.

Anzu

Anzu is a lightweight web application development framework with Mako templating, gettext i18n, validators and sessions; based on Facebook's Tornado.

Effo Home | Core | Add-ons | Framework | GPLed | Reports Stable Code BaselineSource code on SVN::trunk will be updated day-to-day, so if you need newest code, please get it from SVN::trunk, and maybe it cannot be compiled or has big bugs. While stable code will be tagged onto SVN::tags from the SVN::trunk after testing. When building up together with the code from other Effo member project(s) (e.g. Effo Core), you'd better refer to the Effo Code Baseline, so please read the baseline ID put on SVN::trunk/code_baseline. Whenever a new developer join the project, we'll make a source branch for the new member on SVN::branches. The reviewed code will be commited onto the SVN::trunk. For some special versions of the source code we'd also make the branches on SVN::branches. Please pay attention to the Effo Code Baseline to make the life easy.
