This updates handleGetBlockchainInfo to properly return blockchain info
in the case of an empty blockchain where only the genesis block exists.
Also added tests to cover
handleGetBlockchainInfo
.This can be tested manually with an empty blockchain by running
dcrd
with--connect=127.0.0.1
(so that it doesn't connect to any peers) and--datadir=~/some-tmp-dir
to give it an empty database.Fixes #2235
