Is there any sample code that uses that? You're talking about these in

   /** notification callback function.
    * This will be called by notify_func2() by default.
    * @deprecated Provided for backward compatibility with the 1.1 API. */
   svn_wc_notify_func_t notify_func;

   /** notification callback baton for notify_func()
    * @deprecated Provided for backward compatibility with the 1.1 API. */
   void *notify_baton;

I tried to use them, but I can't assign anything to them. This code doesn't work:

import svn.client
import svn.core

def n(*a):
   print a

pool = svn.core.svn_pool_create(None)
client_ctx = svn.client.svn_client_create_context(pool)
client_ctx.notify_baton = n

Trying to set client_ctx.notify_baton2, client_ctx.notify_func and
client_ctx.notify_func all get some error:

TypeError: argument number 2: a 'C/C++ pointer' is expected, 'function(<function
n at 0xb76c4a74>)' is received

Also, the script doesn't use the recurse flag to svn_client_ls(), to save memory
and make the script a little easier to write, so there wasn't a need for the

BTW, what is the ordering of results from a recursive svn_client_ls() call?
