"""Base class for callbacks structure for svn.ra.open2.
Ra users may pass an instance of this class as is to svn.ra.open2
for some simple operations: as long as authentication is not
required, auth_baton may be None, and some ra implementations do not
use open_tmp_file at all. These are not guarantees, however, and
all but the simplest scripts should fill even these in.
The wc_prop slots, on the other hand, are only necessary for commits
and updates, and progress_func and cancel_func are always optional.
A simple example:
class Callbacks(svn.ra.Callbacks):
def __init__(self, wc, username, password):
self.wc = wc
self.auth_baton = svn.core.svn_auth_open([
svn.client.get_simple_provider(),
svn.client.get_username_provider(),
])
svn.core.svn_auth_set_parameter(self.auth_baton,
svn.core.SVN_AUTH_PARAM_DEFAULT_USERNAME,
username)
svn.core.svn_auth_set_parameter(self.auth_baton,
svn.core.SVN_AUTH_PARAM_DEFAULT_PASSWORD,
password)
def open_tmp_file(self, pool):
path = '/'.join([self.wc, svn.wc.get_adm_dir(pool), 'tmp'])
(fd, fn) = tempfile.mkstemp(dir=path)
os.close(fd)
return fn
def cancel_func(self):
if some_condition():
return svn.core.SVN_ERR_CANCELLED
return 0
