Python based http server

[Doug]

I am thinking of using a Python based HTTP server instead of Apache.

I would be interested in one that employed generators and coroutines. I
know those are fairly new features of python, so maybe nothing is
available yet.

coroutines are not a part of Python. Twisted, the best way to write
standalone Python HTTP servers, can use generators productively,
see e.g. http://twistedmatrix.com/documents/howto/flow (but it will
make little sense to you until you understand more about Twisted).

I thought the yield thing in Python 2.3 was a couritine implementation.
Is there a difference between generators and coroutines?

What's the advantage of writing your own HTTP server vs using Apache +
mod_python?

Yes, coroutines are more general than generators.
The code execution is always resumed from the point of calling with
generators, while with coroutines that's not the case.

Why take a ham to scratch a poor fly ?

You even can make a complete server in a windows exe ! hu ! incredible
isn'it ?

And the server will be faster...

Yes. Never used coroutines, so not going to explain that, but
coroutines were (and are, I guess, but not certain) part.of Stackless
Python. Stackless is a separate Python implementation, forked from
CPython. It's currently going through big changes.

Twisted certainly has some virtures. But semi-coroutines, at least, are
part of Python--and therefore it's easy to build full coroutines. See:

http://gnosis.cx/publish/programming...python_b5.html

It's certainly quite possible to use those for a somewhat different
switching framework than Twisted gives you.

(please don't top quote)

Coroutines have a completely separate stack which is saved when they yield,
so you have a load of nested function calls and yield from deep in the
middle of them.

Generators save only a single stack frame, so all yields must come directly
from the generator, not from functions which it calls.

You can use generators to get a similar effect to coroutines by nesting
generators and propogating the yields back up the chain, but this has to be
done explicitly at every level.

Given your expressed requirements: avoiding Apache and using generators,
it sounds a lot like you are doing this merely as a learning experience
or something. After all, who ever heard of "uses generators" as a
practical requirement for a web server?

If you have real requirements, let us know. Otherwise the only
good "advice" you will hear is "what's wrong with Apache"?
