Webware for Python

Feeling a little frustrated with Webware, I figured I'd just try to
read the whole thing so I'll understand it better.  Anyway, I thought
I'd document this, by documenting chronologically all the steps that
happen when a request is made to Webware.  I find something like this
can help a lot when there's a lot of methods in various objects, all
of which talk back and forth quite a bit.

This is intended more for someone who wants to modify Webware than
someone who just wants to use Webware.  But I guess much of the point
of open source is that those are often the same thing.

I got a little tired of reading source before I came to understand
what ServletFactories were about.  I feel like there's a philosophy
behind those, but I'm not sure what it is yet... methods that return
classes?

Anyway, feedback and corrections are welcome.  I marked things to
write or places I felt confused with @@.  If I can get this fully
accurate, I think it would make a good addition to the documentation
for WebKit.

Re: [Webware-discuss] Documentation: Anatomy of a Webware Transaction From: Irene Barg <ibarg@as...> - 2001-03-27 13:34 Ian, As a new user of Webware, I found this documentation useful, especially if one were to try to debug a problem. I'm not sure how it fits into the official Webware documentation, but certainly docs like this one, as well as Chuck's "Introduction to Webware for Python" should be made available at the Webware site.

So this is an expansion on the 9 steps outlined in the WebKit User's Guide Overview? Was it Webware in general you are frustrated with or just WebKit? And are you frustrated as an "ordinary" user or someone who wants to modify it? >I got a little tired of reading source before I came to understand >what ServletFactories were about. I feel like there's a philosophy >behind those, but I'm not sure what it is yet... methods that return >classes? Servlet factories do not return classes; they return servlets, e.g. instances. Basically, the application object keeps a map of extensions to servlet factories. When the application responds to a request, it first checks its servlet cache. If it has no available servlets for the request (because it never created them or they are busy serving responses), it asks the right servlet factory to create one. Since the factories are fairly "opaque" they can do whatever fancy stuff they want to in creating the servlet. If you decide to make up your own kind of file, you can give it a unique extension and make a servlet factory for it. >Anyway, feedback and corrections are welcome.

I'll take a look later today. -Chuck

It's in the proceedings of the 9th Python conference. Unfortunately, it appears that they still haven't put the proceedings on-line. I assume they will at some point, since they did for all the other conferences. -Chuck

Yes, just longer and more concrete. I've tried to include all the method names and such. > Was it Webware in general you are frustrated with or just WebKit? And are > you frustrated as an "ordinary" user or someone who wants to modify it? Well, kind of both... I encountered an ordinary user problem, and instead of experimenting I wanted to look at the Webware code so that I could know why the problem occurred and what I had to do to fix it. Basically I was just confused. I haven't revisited it yet, so I suppose I'm still confused, but more confident that I can figure it out this time. One thing I appreciate about CGI is that I understand the entire process very well (because it is very simple). One thing I very much disliked about Zope was how opaque it felt to me. I'm hoping Webware can provide a middle ground -- simple, but not too simple. -- Ian Bicking Colorstudy Web Design ianb@... http://www.colorstudy.com homepage: http://www.colorstudy.com/ianb 4769 N Talman Ave, Chicago, IL 60625 / (773) 275-7241
