Archangel
=========
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
What Archangel provides
------------------------
* Pre-forking Webserver
* WSGI connector
* The ability to run multiple dissimilar WSGI apps in the same process and
route requests to them individually based off of PATH_INFO or HOST headers
What Archangel does not provide
--------------------------------
* 'Cron' like functionality, this is now implemented via Tulip_. get a copy of
the mainloop with ``loop = tulip.get_event_loop()``, then attach your cron
function with ``loop.call_repeatably(15.0, my_cron)`` which will call your
``my_cron`` function every 15 seconds
* Unix Signal support, this functionality is already provided by Tulip_ via the
``add_signal_handler`` functionality
* Long running background tasks. Tulip_ can be used to launch background
contexts via ``call_soon``. note that CPU bound tasks should ``yield``
periodically to prevent blocking of other tasks or use ``run_in_executor``
provided by the main loop.
Possible Future Features
-------------------------
* Internal 'signalling' allowing applications to signal each other and respond
accordingly
Compatibility Notes
--------------------
* For performance, any 3rd party library you use will need to be
tulip_/pep-3156_ compatible and return a future on blocking calls so that it
may be ``yield from``'d. libraries using open() and socket.socket or other
blocking calls will still work without issue but will prevent other requests
from being handled while the system call is blocked
* To use traditional style locks and events, use the implementations in tulip_
rather than the ``threading`` library
TWIG: Tulipe Webservices Gateway Interface
------------------------------------------
Archangel provides a test-bed for developing a new protocol loosely based
off of pep-3333_/WSGI, Designed for use with Tulip_ and providing a more
'stream' like interface. This can be used to implement long polling clients as
well as support traditional WSGI like request/response through the use of
middleware that will be bundled with Archangel.
An inital draft of the TWIG spec can be found here__
__ http://code.pocketnix.org/archangel/file/tip/TWIG
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
Getting the Latest version
---------------------------
The latest version of Archangel can be obtained with mercurial/hg using the
following command:
hg clone http://code.pocketnix.org/archangel
