| derive class from Client |

Hi all,
my intention is do derive a subclass from the Client class
and add
some custum non-standard functionality (filters for listings
etc.).
What I tried is:
#######<file pytest.py>########
import pysvn
class ExtClient(pysvn.Client):
pass
###############################
however, this gives me the following error:
###############################
Traceback (most recent call last):
File "pytest.py", line 3, in <module>
class ExtClient(pysvn.Client):
TypeError: Error when calling the metaclass bases
function() argument 1 must be code, not str
###############################
Ho can I derive classes from Client?
thanks in advance for any hint,
clemens

It's difficult as the class is written in C++ (btw, pysvn.Class() is a function that returns an object of type pysvn._class - that's why you're getting the errors about needing different function arguments). As far as I can figure out the only way to really do it is something like below.
Cheers,
Stephen
class Client:
"""
A wrapper around a pysvn client. This creates a client and wraps calls to
its functions.
"""
client = None
def __init__(self):
; """
; Create a pysvn client and use it
; """
; def get_login(realm, username, may_save):
; user = "me"
; log.debug("setting get_login with username %s" % user)
; return True, user, "", False
c = pysvn.Client()
; c.callback_get_login = get_login
;
c.set_store_passwords(False)
; c.set_auth_cache(False)
; #Using self.__dict__[] to avoid calling setattr in recursive death
self.__dict__["client"] = c
def is_url(self, url):
; """Override the default is_url which just tells you if the url looks
sane. This tries to get info on the file...
; """
; try:
; self.client.info2
(url)
; return True
; except pysvn.ClientError:
; return False
def __setattr__(self, name, val):
"""
; This special method is called when setting a value that isn't found
; elsewhere. It sets the same named value of the pysvn client
"""
; #BE CAREFUL - assigning class-scope variables anywhere in this class
#causes instant setattr recursion death
; setattr(self.client, name, val)
def __getattr__(self, name): """
; This special method is called when something isn't found in the class ; normally. It returns the named attribute of the pysvn client this class
; is wrapping.
; """
; return getattr(self.client, name)
