[albatross-users] problems with a RandomModularSessionApp

[Chiron Consulting]

New to albatross, delighted with it so far, having a problem that I 
can't figure out.  Checked the archive, and don't notice anybody else 
having it, so I thought I'd ask.

1. Running apache 2.0.44, mod_python 3.0.3, python 2.2, and albatross 
1.01 ... everything seems to run fine, examples all work

2. I've got apache configured to handle any/all .html files in the 
documentroot directory using my mod_python handler.  this worked fine.

3. I built a trivial SimpleApp-based albatross program, which also works 
fine:

<code>

# myhandler.py
from albatross import SimpleApp
from albatross.apacheapp import Request

class StartPage:
    def page_display(self, ctx):
       ctx.run_template('start')

# note: the start template is trivial, with no replaceable parms.
# i plugged those in, and it also works fine.

class myApp(SimpleApp):
    def __init__(self):
       SimpleApp.__init__(self,
             base_url = 'myhandler.py',
             template_path = '/usr/local/apache/htdocs/templates',
             start_page = 'start',
             secret = '-=-secret-=-')

app = myApp()
app.register_page('start', StartPage())

def handler(req):
    return app.run(Request(req))

</code>

4. The 'start' template in the above example was a trivial html file, 
with no replaceable parms.  I added replaceable parms, and implemented a 
  page_enter() method for the StartPage class, and all went as expected.

5. Here's where I start running into problems.  I want to use the 
RandomModularSessionApp to build a more sophisticated app.  Here's the 
mod_python handler code:

<code>

from albatross import RandomModularSessionApp
from albatross.apacheapp import Request

class myApp(RandomModularSessionApp):
    def __init__(self):
       RandomModularSessionApp.__init__(self,
             base_url = 'myhandler.py',
             page_path = 'htdocs',
             start_page = 'start',
             secret = 'same-secret-as-always',
             session_appid = 'whatever')

def handler(req):
    app = rpApp()
    return app.run(Request(req))

</code>

and here's the module for the (still trivial) start page:

def page_display(ctx):
    ctx.run_template('start')


With the albatross session server running, an attempt to access this app 
at the URL "http://localhost/" generates the following traceback error:

Template traceback (most recent call last):

     new_loc = self.redirect_url(loc)

   File "/usr/local/lib/python2.2/site-packages/albatross/apacheapp.py", 
line 34, in get_servername
     return self.__req.connection.server.server_hostname
AttributeError: server


I have no idea what's going on here, or how to fix it.  Any ideas?

Thanks,
