Ian Bicking [mailto:[EMAIL PROTECTED] wrote: I would also like to see a standard container. I don't think it even has to be terribly intrusive or conformist -- it just has to create request and response objects, and map those to some resource, which would be somewhat more abstract than servlets. My private experiments suggest that it isn't that hard to make an abstraction layer for Webware and mod_python - in these cases, the main differences are where one finds certain facilities (eg. request and response streams, content type and encoding information) and whether those facilities are implemented by separate objects or not. Providing an environment for a Webware-style plug-in (which takes responsibility for certain resource types) within mod_python isn't an insurmountable problem either, and I'm convinced that there's enough common ground in Twisted and Zope to cover those frameworks as well. Under the covers, in Zope Products, Zope isn't so different after all. I was trying to pursue this kind of unification after PyCon, but I'm afraid I lost momentum, and actually writing code is much more satisfying than trying to organize stuff. I'd still like to pursue it, though. The shootout paper was certainly very interesting, and recent coverage of Twisted Web suggests that it wouldn't be absolutely necessary to put the whole of Webware on top of Twisted to get a decent application environment with a different execution model: http://twistedmatrix.com/users/nafai/pycon-paper/tw_deploy-01.html That would be compelling: a common environment which runs on servers with completely different underlying scalability models (threads, processes, asynchronous tasks) - I doubt that there's such diversity between the mainstream Java application servers. I've been working on a component idea, for adding functionality to servlets -- a bit finer grained than plugins. It's in the Webware sandbox (webware-sandbox.sf.net), in ianbicking/Component, with a user authentication component as an example. I've also used it for (my still in heavy development) form processing toolkit, in FormEncode, also in the Sandbox. Perhaps I should get around to looking at this as well.

Re: [Webware-discuss] Zope vs Webware (Not Really)
I like webware becuase you can write all of the business logic as normal python modules, test them outsite of a webserver w/ full debugging, and then call it from a very small servlet. I hate debuggin in a web server. Here is an example of how I use Webware. I need to pull data from Quickbase.com - a web based database ASP type service. 1) Created a generic QBClient module in python that interacts w/ Quickbase --- All coding done w/o webware at all 2) Create a servlet with this method: def prepareReport(self): qb = QBClient() qb.userName = 'This is not my qbusername' qb.passwd = 'This is not my passwd' qb.database = 'this is not my database' ctable = qb.getCVSTable() -- return CVS data csvdata = ASV.ASV() ASB is a module to parse CVS data csvdata.set_field_names(['Name','Products','Alt1','Alt2','Alt3','Alt4','Alt5']) csvdata.input(ctable,ASV.CSV()) csvdata.data.pop(0) - the top row is header info, lose that self.records = csvdata 3) create a PSP file that uses self.records %def writeTableRecord(row):% tr TD class=reportSectionCell align=left style=text-align:left;b%= row['Name']% TD class=reportSectionCell align=left style=text-align:left;b%= row['Products']% /tr % end % on the other hand if you are building a pretty standard website Zope is much easier. I build a large website and support site in Zope and it was very easy to build up a FAQ and knowledge base. Of course when I had to integrate that Knowbase into a MsSQL database things got interesting. -Aaron Chris Bruce wrote: I truly believe that Python is probably the best web development language around.

Re: [Webware-discuss] Zope vs Webware (Not Really)
I am not to worried about process vs threads right now. My only concern is rolling my own security and stuff like that. I like how Zope's security allows you to use different acl_users folder that supports different authorizations--although I want groups. But on the flip-side, one of the reasons I am reluctant about Zope is that anything I do will only work in Zope. It is not very useable outside Zope. This is the one drawback about developing with python for web-apps compared to Java right now. There are no real standards for developing/deploying python web-apps and it almost always depends on what python app server/apache mod that you use. I hate the fact that the Java community has all these crazy best practices for developing web apps, however some things are kinda cool about the servlet containers when it comes to standard ways of defining security and uri mapping. The idea is really nice that you can take a java .war file (web archive) and drop it into most any java app server and it is ready to go. Then the admin can just modify some xml files. I am not sure if it is good or bad to have some kind of standard container? I wish developing python web-apps could run on most any python app server. But after spending many years developing java apps, I can say for sure that java is really dissappointing for developing web apps. But, I think Webware has some great potential with plug-ins. I just wish there were more of them! But that might be the way to go right now, developing the Zope-like things that make it easy to build web-apps in Zope as plug-ins for Webware.

RE: [Webware-discuss] Zope vs Webware (Not Really)
Ian writes: Personally I detest XML files -- the beauty of OO is when data is not exposed, just methods, and XML exposes data in an inflexible way. But the interchangeability would be great. At Autodesk, we had an object-oriented approach to XML for the Streamline engineering collaboration service. We had class libraries in both C++ and Java for client code (web apps, server apps, and publishing apps), who used objects rather than XML text. XML was used to persist CAD data in packages, crack open packages to populate databases, and stream structured metadata from databases to web clients. It is very much like C# uses attributes to serialize objects in XML, but we had a finer degree of control. The wrong XML definition was shown to balloon text size to an unacceptable degree pretty quickly. More recently, I used Webware/Python to prototype an online catalog for a local not-for-profit institute serving the visually-impaired. The catalog was defined in XML. (No formal schema, just me inventing a syntax. The initial catalog has 90-100 entries, enough to give me a warm feeling that the XML has pretty good coverage.) One of the goals for the site design was to be able to maintain the web presentation separately from the catalog content. The website look and feel would not change often, but products would be added or deleted from the catalog on an ongoing basis, prices would change, etc. [It should be noted that the online catalog and site are designed only for presentation, and not to support direct purchase at this time.] I got two things from python: 1) A nice class hierarchy for the web page types (welcome, show items in a given category, show search-by-keyword results, show specific item) along with a parallel class hierarchy for the XML filters needed to support them. 2) Good built-in support for SAX parsing, without validation. Given that, what I got from Webware was a straightforward and repeatable organization for the WriteContent method on my python server pages: # parse values from the HTTP request, if any, ... # Read the catalog and render the page, for example # base = os.path.dirname(self.request().serverSidePath()) pp = GoreySearchPage(self, base, 'Gorey.xml', ...) pp.read() pp.render() The read() method parses the XML file, pulling out the juicy bits. The render() method writes the HTML response. Granted, the python statements to crank out the HTML response were tedious to write, but there is a lot of common content across the page types, which was well-supported by the class hierarchy. I was able to get a feature-rich site running in about a week, with no previous Webware experience and somewhat rusty python skills, and to extend the functionality easily a couple times already. On the XML side, the catalog file worked as I intended it to. Changes were automatically reflected in the website, even if the change added or removed a product category, changed the number of pages occupied by a category, or added/removed an entry from a keyword search result on screen. (An aside: pagination is very important when delivering data to the visually-impaired, some of whom might be using a text-to-speech system to READ webpages to them, others who might be using very large type. As a sighted user, I tend to want many results on a page. But I have also experienced the tedium of the mechanical voice droning on and on. We are experimenting with various strategies for separately formatting content to suit users with various classes of visual impairment.) So Webware seemed to be the right venue for getting a proof-of-concept done in a short amount of time, while still having an understandable and extensible design. It remains to be seen whether we will go live with that architecture.

Re: [Webware-discuss] Zope vs Webware (Not Really)
Hi, Chris.
I muddle my way through both Zope and Webware almost daily. I'm neither
a novice nor an expert with either.
With mod_webkit, you get to take advantage of Apache's built-in
functionality. If mod_ssl is installed/configured, then secure stuff
dynamically generated through webkit is a given. Trying to get Zope and
SSL to play nicely is a far cry from easy. Plus, someone's going to
have to admin the Apache server anyway (incl. vhosting), so why not
keep things simple?
Webware is knowing Python and some HTML, even CSS if you like. You
don't have to learn yet another markup language or worry about crazy or
non-intuitive syntax (e.g. dtml-call dict.update({'a': 'b'}). You'll
write fewer lines of code using Webware since you don't have to worry
about closing DTML tags, which can also cause some headaches if you're
deeply nesting things.
Also, whether you shove data into a database or use pickles in the
filesystem (not recommended for concurrency reasons), that information
is available system-wide. MiddleKit looks promising and works, though I
haven't gotten it to work 100% with MySQL yet (missing a req'd module,
too much other stuff to do). Getting stuff out of the ZODB, as far as I
know, isn't easy or intuitive.
In Zope, I find myself writing a lot of External Methods to do the
'heavy lifting', and call them from within the DTML. In WebKit, the
'heavy lifting' is just part of the Python, not a requisite separate
entity.
Wherever I'm not *required* to use Zope, I don't even think about it...
I go straight to Webware/WebKit.

I am not looking to start a debate or anything, just trying to get some
fresh points of view. Some of the reasons why I am looking at Webware:
MiddleKit
mod_webkit
I have had weird ZODB issues in the past.
Maximum use of Python
Features about Zope I like:
Webbased access to development and whole system
Built in Security (no coding)
Super fast to develop and deploy apps
Virtual Host Support
Thanks,
Chris

Re: [Webware-discuss] Zope vs Webware (Not Really)
Thanks for the info. If you have any additional suggestions or comments, please let me know. As far as security, is UserKit useable?

My experience, shared by a number of other people, is that UserKit doesn't help with the interesting problems (like security, authentication, etc), and isn't worth it for the conceptual overhead.

What is meant by this? If it really is an I project and not a we project, I don't think Zope has much to offer you. I tried a while back, but never managed to do anything useful with Zope. To me, Zope seems only appropriate for a large team of developers. The learning curve is pretty steep for one person to climb without someone elses shoulders to stand on now and then.
