This works, but obviously isn't proper:
if serverAddress not in self._handlerCache:
serverAddress = ('127.0.0.1', serverAddress[1])

self._handlerCache looks like this:
{('127.0.0.1', 8080): [], ('127.0.0.1', 8086): []}

[Webware-discuss] Starting as user webware with environment variables
My webkit setup requires certain environment variables to be set up in order to use Oracle. I'm starting webkit (using the included script) as user webware, but environment variables are not set, so the webkit instance cannot access the Oracle libraries. I can put the environment variables inline with the startup script and Oracle access works, but then /etc/init.d/webkit stop doesn't stop webkit. It kills the right PID (so it seems), but there are still several threads running. In this case I manually kill the first listed thread and they all die. I saw this question in the Wiki, but haven't seen a solution. Anybody got one?

[Webware-discuss] Using session storage without the cookies
This came out of a previous thread I started. I'm using XMLRPC and I want to take advantage of Webware's session storage without using cookies. What I have in mind is to generate a unique id, store and retrieve variables using that unique id. Basically everything about sessions but the cookie. I'll handle sending and receiving the unique id with the XMLRPC client. Any idea how to do this with Webware's sessions? Randall --- This SF.Net email sponsored by Black Hat Briefings & Training.

I have to keep track of lab data, too. It would be great if you could make this available when you are done. Sure, if it would help you. Here is an overview to see if you are interested. Machines in the lab generate electronic reports for their results. These reports are different for each machine. I built a text parser for each report. The LabRat accepts the report through PHP Website -> XMLRPC -> Python LabRat, determines which parser is needed, parses the results, manipulates the data for uploading, uploads the data to a database. This is the scope thus far. There is also a reporting end that uses Reportlab. I have flexibility in the design of LabRat. Some requests may depend on the result of a previous request, so I will need some form of persistence. I do not know how to implement sessions using XMLRPC. I like Webware's session storage because it lasts between process restarts. Could I use Webware's session storage and couple it with a simple client id system? Client requests id -> server sends id -> client sends data to store and id -> server stores data in session using id as key. Is there any strong reason to use XMLRPCServlet and not Page as a base class for your servlets? If you could use Page, you would get the session storage for free. You can still import all kinds of XML modules and libraries to parse or output XML. I looked at Page and saw that session is called from the transaction. I don't see any advantage to using Page as I could just call session from the transaction. The problem lies with cookies. My XMLRPC client doesn't know what to do with a cookie. That's why I'd like to just get at the WebKit session storage. I could develop my own method for giving session ids to the XMLRPC client.

If you don't define __init__, that of the base class will be called automatically. If you do have to do some work in __init__ (which you likely do, since you say that LabRat contains 'all the business logic'), call XMLRPCServlet.__init__(self) from your own __init__ .

Do they persist? Are they present only in the instance they were set in, or all instances? Is the object re-initialized when it 'wakes'? What is and what is not re-initialized depends on what you have in your YourServlet.awake method; what persists depends on your YourServlet.sleep method. I use awake and sleep to automatically clean out everything that has been stored on self during the request: def awake(self, transaction): Page.awake(self, transaction) # Call base class, which is Page in my case but would be XMLRPCServlet in your's I guess # save the keys in the __dict__ as a template for cleaning up later self._dictKeysStart = self.__dict__.keys() def sleep(self, transaction): Page.sleep(self, transaction) # clean out everything that has been left behind dictKeysEnd = self.__dict__.keys() dictKeysStart = self._dictKeysStart[:] # Use a copy to avoid suicide for key in dictKeysEnd: if key not in dictKeysStart: del self.__dict__[key] I'm certainly not complaining.

[Webware-discuss] webware as general app server for web/xmlrpc/soap ?
I am working on a project in which I have chosen to use xmlrpc. As I set out to look for an app server, I wanted one that would allow code changes without restarting the process(es) and one that is non-blocking. I considered building my own from the Python standard library, and I considered twisted. I'm not comfortable with twisted's deffered solution for writing non-blocking code, and neither solution would let me easily manage the server and reload modules, etc. I had used Webware before for building a website and thought it sure would be nice if Webware did XMLRPC. And lo and behold, to my delight, it does! Multi-threaded, easily managed, dynamically realoading modules. And written in pure Python. So I'm happy. So I ponder. Why isn't Webware more aggressive as a general webservices app server. Is there a SOAP implementation? Would it be difficult to create one? Probably not much more difficult to impement than xmprpc. It seems like such a natural fit. Here are its advantages as I see them: 1. Decoupled from the webserver. Apache does a great job of managing connections. Why try to beat it? Webware focuses on the application side. 2. Multi-threaded. Although the global interpreter lock may prevent scaling on SMP machines (hence twisteds async), I've found the performance to be superb in my experience. It is very responsive while handling simultaneous requests. 3. Manageable. The web interface for managing the service is nice. Being able to reload modules with the server running means more uptime. Webware can also watch mtimes on the files to reload them when they are changed. So what else do you want in an app server? Is there a better app server that 'all the other' Pythoneers are using and I'm just missing? If not, ring the bell! Webware is such a simple and powerful framework for building web apps. It lets me program in Python (unlike Zope) and doesn't force me to use a specialized abstracted framework, but provides easy access to the things I need (http request info). So back to my question. Is Webware intended to be a webservices (web/xmlrpc/soap) app server? If not why? I understand it is not like twisted, supporting every protocol under the sun. It should not be. I think it should stay with http based protocols. But why not support them all? If the glove fits.

The solution is still not evident, but I'm getting closer. ''I believe your problem may be that if you set a cookie and redirect in same request the cookie is ignored.'' So why does it work on the first request when the cookie is first set? I'm not quite sure what you mean by redirect. I'm not 'redirecting' the user. The forward() happens on the application server side and is invisible to the browser. Note that the process works the first time the cookie is set. So why would it not work when a new cookie is set?

Index.py sets session variable. 3. Index.py forwards request to View.py (Not a redirect in browser terms. User has not yet received a response.) 4. View.py reads session variable and produces output to browser. These steps work on a NEW SESSION and continue to work until the session times out.

[Webware-discuss] Performance Concern
I'm having some performance problems. It seems that when a servlet takes a long time to service a request, no other requests are completed until it finishes. The case in which I observed this behavior: I have a servlet that takes input and sends an email using smtplib. Today I had network trouble so it could not connect to the mail server. The servlet would try for about 30 or so seconds to connect before it failed. While it was attempting to connect, !!!no other servlets would respond!!! As soon as it finished, they responded. My app is not in production yet, but this looks like a potential hangup. Does this behavior sound reasonable for webkit? My understanding is that servlets fill requests in serial and that two or more different servlets should be able to fill requests at the same time. Is this correct? If so, then I may need to reconfigure my application because it seems that only one servlet can respond at one time. The serial thing raises another issue. I have been building my application with a controller(Index.py) that receives all requests and directs them (self.forward()) to the appropriate servlet. It makes my program feel more like an application than a pile of scripts. Anyway, I'm beginning to think that my application will only be able to serve one request at a time becuase every requests goes to Index.py before it is forwarded. It really want to use webware (I love Python), so please tell me how I can make it perform well.

lots of good html
The error I get looks like this:
AttributeError: _home_randall_pyrocks_MyContext_real_estate_psp_ba instance has no attribute '_request'
Why can't I access the request object this way? Is (def writeContent: )
the only way to access request, etc. ?
I'm still trying to understand how webware works. Answers or references
to docs are appreciated.
Thanks.

[Webware-discuss] automatic html validation help
I'm trying to configure webware to use the html validation. I've
installed the wdg validation software and now I'm stuck on the SitePage
configuration. I'm new to Python and Webware and probably just showing
my ignorance, but here is an explanation of my problem.
When I override the writeBodyParts method like this:
def writeBodyParts(self):
Page.writeBodyParts()
self.validateHTML()
I get this error when viewing a page that uses SitePage:
TypeError: unbound method writeBodyParts() must be called with Page
instance as first argument (got nothing instead)
The error makes sense. The method expects and instance. But if I feed
it an instance (self), it will loop forever. ???
Here is my SitePage (actually called StarkPage):
from WebKit.Page import Page
class StarkPage(Page):
def writeDocType(self):
self.writeln('''http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd";>''')
def writeBodyParts(self):
Page.writeBodyParts()
self.validateHTML('')
And here is the psp using it:
<[EMAIL PROTECTED] extends="StarkPage"%>
<[EMAIL PROTECTED] method="writeContent"%>
return "StarkVegas.Com"
StarkVegas.Com
that?
I would appreciate any help.
Thanks

[Webware-discuss] new confused user
I've been looking for a better way to write web applications. I've used asp/vbscript and then moved to php on apache/linux. I used the webkit adapter and setup a seperate application directory and it works fine. I added a psp handler in the apache configuration and it works OK too. What I'm confused about right now is the Page/SitePage stuff. From what I understand, psp files use the Page ?servlet? and by default override the writeHTML method. How does writeHTML become the default method? I would like writeContent or writeBody to be the default method because I don't want to have to write <%@ Page method="writeContent"%> in every psp file. Note that the psp files are not in the application directory. The app directory is /var/www/appdir and psp directory is /var/www/html/pspdir. I looked at the examples and this is what I am seeing: <%@ page imports ="sys,os,time,PSP.Examples.PSPExamplePage:PSPExamplePage"%> <%@ page method="writeContent" %> <%@ page extends="PSPExamplePage"%> Do I I have to do all of this with every psp file? Can I define some SitePage with a default method of writeContent so that I can just write content and the rest of the document will be automatically generated?

[Webware-discuss] php convert - need guidance
I've used php for 1 year and I think it's great, but I'm trying to
improve my programming methods and find php is not sufficient for my
needs. I've played around with python and I really like its syntax,
ease of use, oo design, among other things. I've found myself doing oo
in php, trying to separate core logic from presentation logic and create
reusable code. PHP will work, but is not designed for this. Java looks
like a good solution. It is a very well structured language that has
mature solutions and a huge user-base. High quality open source
solutions such as JBOSS are inviting! Although, over the years, I've
shyed away from Java for a few reasons. 1. Slower development due to
typing variables and compiling code. 2. Not open source. I prefer to
use open source when it is available.
My opinions (and/or feelings) right now:
Python is my language of choice because of its fast development, oo
design, portability, maturity, and good user base. Now I'm looking for
a good application server. I don't like a servlet only solution. I
prefer to create xhtml documents with coded inserted in it (psp style)
so that it still looks like an xhtml document. But I only want display
logic in the psp file. What I despise is:
method 1
\r\n";
echo "\r\n";
echo "".$title."\r\n";
echo ...
I prefer:
method 2
require('datalogic.php');
...
I use php examples because that's what I'm familiar with.
I've used method 1 for a while and this is what I see in the servlet
only approach. method 2 makes for much cleaner presentation xhtml files.
Templates. Don't like them. Why use templates when method 2 works fine
and is clean.
I'm new to servlet jargon, so please excuse me if I show my ignorance.
It looks like with webware, I can create a psp file that, when
requested, can call on a servlet, which using various classes does the
dirty work and returns the results to the psp file for display. Is this
correct? Is webware the best open source application server available
to work in this manner? I would appreciate any advice on which
direction I should take. Thanks.
