Thanks. That works. Should I file a bug about that not working?
I got svn.ra.open2() and svn.ra.get_dir() working, but I'm unable to make the
receiver/baton part of
l = svn.ra.get_log2(session, None, 1, 4, 0, False, False, [], receiver,
None)
work. The receiver is supposed to be a svn_log_entry_receiver_t. I tried to do
def receiver(baton, entry):
print entry
but I get
TypeError: argument number 8:
How does swig wrap svn_log_entry_receiver_t?
I have not been able to find any python sample code that uses svn.ra.
