commit c076038e82fcd5f5188ec7f889c9c9dc5d5eafd3 Author: Damian Johnson atagar@torproject.org Date: Sat Aug 24 10:45:14 2013 -0700

Handling bridge-ip-versions as a general extrainfo field

In commit 0d01ad6 I added support for the 'bridge-ip-versions' lines. These are only relevant to bridge descriptors, and ineed don't presently appear in the extrainfo consensus. However, that once could be said about the 'bridge-ips' field too.

It's wrong for bridge attributes to appear on public relays, but there's nothing in the spec prohibiting it. Hence moving this attribute's handler to the common ExtraInfoDescriptor parent class. --- stem/descriptor/extrainfo_descriptor.py | 36 +++++++++++++++---------------- 1 file changed, 17 insertions(+), 19 deletions(-)
