From ad6ac1244fd175d08bcee62060a9a0b7975930fb Mon Sep 17 00:00:00 2001 From: Brandon Williams Date: Wed, 14 Mar 2018 11:31:45 -0700 Subject: connect: discover protocol version outside of get_remote_heads In order to prepare for the addition of protocol_v2 push the protocol version discovery outside of 'get_remote_heads()'. This will allow for keeping the logic for processing the reference advertisement for protocol_v1 and protocol_v0 separate from the logic for protocol_v2.
