So checking if there is an exposed, would raise an error itself! (as it
should provide None as default)
So we'll have to use other means of checking, or we can't use
dictionaries right away. and keeping them all opened, doesn't seem safe
to me.

But i simply question how many people will be changing this.. Most of it
can be done using regular cp2 'pages'.

The ticket gave me another question:

This one bit me not long ago. .i'm trying to reconstruct the problem
while i'm at it. So if you don't have much time:
skip the rest of the email.

/Summary: it shows some odd behaviour using index, default and regular
methods.../
<flames state=off>
<start of large post about parameter usage. . if anyone can use this for
documentation purposes; go ahead>

What should, and will hapen using the following:
class Root(object);
    def index(self,*p):
          if p:
              print `p`
          else:
              print 'index!'
     index.exposed = True
cpg.root = Root()

Ok. if i go to "http://localhost'"  or http://localhost/" i will see
"index!" if i add anything to the location bar, it will fail:
http://localhost/bla/pir:

Traceback (most recent call last):
  File "C:\module\cp2\cherrypy\_cphttptools.py", line 206, in doRequest
    handleRequest(wfile)
  File "C:\module\cp2\cherrypy\_cphttptools.py", line 372, in handleRequest
    func, objectPathList, virtualPathList = mapPathToObject()
  File "C:\module\cp2\cherrypy\_cphttptools.py", line 504, in mapPathToObject
    raise cperror.NotFound # We didn't find anything
NotFound

So that doesn't work?!

now i add root.bla similar to index. .
    def bla(self,*p):
        if p:
            return  `p`
        else:
            return 'bla'
    bla.exposed = True

Okay. here goes: http://localhost/bla and http://localhost/bla/ work
fine. . it displays "bla". .
and going to /bla/pir shows ('pir',)  .. perfect!! _So something is
wrong with index?_. .

Now.

If if would change the bla, to expect 1 parameter, wich i would like to
be defaulted, it's becoming a keyword parameter.
 >>> bla()
 >>> def bla(first='first',*p):
...    print first,p
...
 >>> bla('pir')
pir ()
 >>>

that's nice. . (though one might not expect this to happen, as it's a
keyword parameter, but i like the behaviour)
So here's my new bla:
    def bla(self,first='first',*p):
        return  `first`,`p`
    bla.exposed = True

/bla returns ; ("'first'", '()')
/bla/pir/feedz/iz/doe returns ("'pir'", "('feedz', 'iz', 'doe')")
exactly what i want it to. .

Back to index.. .

i'll replace my index method with the following;
    def index(self,first='first',*p):
        return  `first`,`p`
    index.exposed = True

http://localhost:9000/index and http://localhost:9000/ both return:
("'first'", '()')
But if i move to /someothername it will crash, telling me:

Traceback (most recent call last):
  File "C:\module\cp2\cherrypy\_cphttptools.py", line 206, in doRequest
    handleRequest(wfile)
  File "C:\module\cp2\cherrypy\_cphttptools.py", line 372, in handleRequest
    func, objectPathList, virtualPathList = mapPathToObject()
  File "C:\module\cp2\cherrypy\_cphttptools.py", line 504, in mapPathToObject
    raise cperror.NotFound # We didn't find anything
NotFound

So we introduce root.default. . . This clearly solves the problem.
    def default(self,first='first',*p):
        return  'default:',`first`,`p`
    default.exposed = True

This solves nearly all of my problems!! now i will just delete the
root.index, cause my default is the catch all (i assume)..
Now, all unkown pages, i except to be cought by the default. . . this
would be perfect!!  (i was writing a wiki at the time,
so going to /wiki would come up with the wiki's frontpage.. that would
be nice. . but. .
no, this doesn't work. . if i go to http://localhost/ and i have no
root.index, i'm lost . . It is not caught by the default!!
so _default is not run when there is no root.index and the index would
be run if it was there..._!

Traceback (most recent call last):
  File "C:\module\cp2\cherrypy\_cphttptools.py", line 206, in doRequest

  File "C:\module\cp2\cherrypy\_cphttptools.py", line 504, in mapPathToObject
    raise cperror.NotFound # We didn't find anything
NotFound

so now i need to redirect my root.index to root.default. . .
a. - how do i do it simple, if default would use generators (thus return
a generator) ?  cause
      root.index(self): return self.default() would clearly not be a
sollution then
b. - _can't default become the catch all, even for missing indexes_? As
i thing this behaviour would be more 'natural' and expected.

</flames>

I hope this can serve both for documentation purposes, as well as for
feature request/bugreport . . .

and (okay, flame me for starting this infamous debate again). . .
_if default would become the catch all, even for missing indexes, can't
we simply drop default, and have index have the default behaviour as well?
_I think it would be much simpler then. .
