now it works ... and running it for 100'000 revisions slowly increases
the memory. but the main problem seems to be replay. you have an
example? i did not find anything in the test subversion testcases.


import svn.client
import svn.core
import svn.ra

pool = svn.core.Pool()
client = svn.client.create_context(pool)
client.config = svn.core.svn_config_get_config(None)
client.auth_baton =
svn.core.svn_auth_open([svn.client.get_simple_provider(pool)], pool)

ra = svn.client.open_ra_session("http://gcc.gnu.org/svn/gcc", client,
def rcvr(orig_paths, rev, author, date, message, pool):
    if orig_paths is not None:
        for x in orig_paths:
    print rev
svn.ra.get_log(ra, [""], 0, 100000, 0, True, False, rcvr)

client = svn.client.create_context(pool)
