From: Leif Ryge Date: Fri, 5 Feb 2016 11:37:22 +0000 (+0000) Subject: remove introducer's set_encoding_parameters X-Git-Url: https://git.rkrishnan.org/%5B/%5D%20/uri/frontends/COPYING.GPL?a=commitdiff_plain;h=56a9f5adaf9cddf8cf5613d153482026564e9d3b;p=tahoe-lafs%2Ftahoe-lafs.git remove introducer's set_encoding_parameters I'm not sure why this ever existed, but it doesn't appear to be used. (If an introducer called a client's set_encoding_parameters method it would keep the provided parameters in an instance attribute but would not actually use them.) --- diff --git a/src/allmydata/introducer/client.py b/src/allmydata/introducer/client.py index f463c120..be440067 100644 --- a/src/allmydata/introducer/client.py +++ b/src/allmydata/introducer/client.py @@ -28,9 +28,6 @@ class WrapV2ClientInV1Interface(Referenceable): # for_v1 for ann_v1 in announcements]) return self.original.got_announcements(anns_v1, lp) - def remote_set_encoding_parameters(self, parameters): - self.original.remote_set_encoding_parameters(parameters) - class RIStubClient(RemoteInterface): # for_v1 """Each client publishes a service announcement for a dummy object called the StubClient.
