A high performance webserver based off tulip (pep-3156)
Project description
Archangel is a webserver designed to be fast and easy to use for personal usage. It was created to replace an internal webserver based off of flup for fcgi and wsgiref for http serving (basically anything would be an improvement) as well as explore the new pep-3156/Tulip based library by Guido van Rossum
Archangel is designed to be ‘fast’. This does not mean however that archangel is fast, Archangel is instead intended to explore how fast a server using an event loop based of tulip can be made to go and what is needed to get it there.
As an additional side effect it should serve as a light house in the fog as to what you should or should not do with Tulip (Of course it is still yet to be determine on which side of the divide Archangel ends up)
Tenets:
- Only do things when we need to:
Do things “Just in Time”
- Only do things we have to:
Be lazy
- Do it quickly:
Go back to sleep as fast as possible
WSGI-STREAM
Archangel also provides a test-bed for developing a new protocol loosely based off of pep-3333 but designed for the needs of streaming and for use with tulip. Due to the use of the yield from construct by tulip compatible event loops, using yield to incrementaly return a body is not possible. As such, an alternate interface is needed to support both writing the body as one whole chunk and iteratively generating the body as well as providing compatibility with the ideas of WSGI for ‘wrapping’ apps in middleware. At this time (version 0.1) file like proxies are being used for both the request and the response that can be ‘corked’ or paused until start_response has been called, preserving a similar interface to WSGI and allowing a WSGI-STREAM middleware to fully emulate a WSGI middleware interface
Requirements
Python 3.3 or greater
Distutils2 (to replace setup.py, a fallback is provided)
A copy of the Tulip library
PyYaml for parsing the config files
