Can svn_config_enumerate() be called from python?

Hi all,

I've been looking all over the place giving myself a rather drastic crash
course in python, subversion, swig, viewcvs, trac, the subversion book etc in
an attempt to answer for myself whether or not I can call svn_config_enumerate
from python using the swig bindings.

In subversion 1.2.1 I can call it but only if the callback func parameter is
passed as None - anything else causes "TypeError: Expected a pointer".

Can anyone either show me how I can use a callback python function with
svn_config_enumerate, tell me I should be doing this another way (e.g. just
use config methods that don't require a callback) or set me straight on what
is and isn't possible so that I can perhaps focus my research efforts on
helping to fix (in subversion with a patch if necessary) my problem.

I haven't found a single Python invocation of svn_config_enumerate() in my
travels back through time in mailing lists and my wading through current
versions of trac, viewcvs, the subversion book and so on.

A quick bit of background for you. I started on this problem when I submitted
a patch to the ViewCVS project to allow authorisation using the mod_authz_svn
configuration file. I hated my patch because it's hacky and it used some trac
code which isn't on (my patch was meant as an example of what can work and
stated I didn't mean for code to be incorporated directly into viewcvs by
stealing it from trac). I wanted to replace the code borrowed from trac with
python code that calls the exact same subversion apis as mod_authz_svn does
instead of writing new code to interpret the mod_authz_svn config file (why
reinvent the wheel and a whole host of new mistakes to boot?) and then I ran
into the problem with svn_config_enumerate.



Note: I originally posted to the users list (well, I asked where to post and
in response someone suggested I just ask there) but the result of my googling
is that I've decided my questions are getting too technical for the users
list, apologised and moved my hunt for answers to this list instead.
