From: Brian Warner Date: Mon, 23 Apr 2012 22:02:22 +0000 (-0400) Subject: Fix introweb display for mixed V1/V2 clients. Closes #1721. X-Git-Url: https://git.rkrishnan.org/pf/content/en//%22%22?a=commitdiff_plain;h=84c9f3bfb4bdfde0e771d6ee291689b0a691e623;p=tahoe-lafs%2Ftahoe-lafs.git Fix introweb display for mixed V1/V2 clients. Closes #1721. This significantly cleans up the IntroducerServer web-status renderers. Instead of poking around in the introducer's internals, now the web-status renderers get clean AnnouncementDescriptor and SubscriberDescriptor objects. They are still somewhat foolscap-centric, but will provide a clean abstraction boundary for future improvements. The specific #1721 bug was that old (V1) subscribers were handled by wrapping their RemoteReference in a special WrapV1SubscriberInV2Interface object, but the web-status display was trying to peek inside the object to learn what host+port it was associated with, and the wrapper did not proxy those extra attributes. A test was added to test_introducer to make sure the introweb page renders properly and at least contains the nicknames of both the V1 and V2 clients. --- diff --git a/src/allmydata/introducer/common.py b/src/allmydata/introducer/common.py index 2f6e9c89..c7347971 100644 --- a/src/allmydata/introducer/common.py +++ b/src/allmydata/introducer/common.py @@ -1,6 +1,7 @@ import re, simplejson -from allmydata.util import keyutil, base32 +from foolscap.api import SturdyRef +from allmydata.util import keyutil, base32, rrefutil def make_index(ann, key_s): """Return something that can be used as an index (e.g. a tuple of @@ -34,7 +35,7 @@ def convert_announcement_v1_to_v2(ann_t): assert type(ver) is str assert type(oldest) is str ann = {"version": 0, - "nickname": nickname.decode("utf-8"), + "nickname": nickname.decode("utf-8", "replace"), "app-versions": {}, "my-version": ver, "oldest-supported": oldest, @@ -90,3 +91,67 @@ def unsign_from_foolscap(ann_t): key_vs = claimed_key_vs ann = simplejson.loads(msg.decode("utf-8")) return (ann, key_vs) + +class SubscriberDescriptor: + """This describes a subscriber, for status display purposes.
