From dd5b0114cf9021e8639e48c2a33f0aaf82aeb14e Mon Sep 17 00:00:00 2001 From: John Newbery Date: Fri, 20 Jan 2017 14:13:14 -0500 Subject: [Trivial] add comment about setting peer as HB peer. This adds a comment to the new logic for setting HB peers based on block validation (and aligns the code below to reflect the comment). It's not obvious why we're checking mapBlocksInFlight. Add a comment to explain. --- src/net_processing.cpp | 10 +++++++++- 1 file changed, 9 insertions(+), 1 deletion(-) (limited to 'src') diff --git a/src/net_processing.cpp b/src/net_processing.cpp index 36a5257635..94faaac37b 100644 --- a/src/net_processing.cpp +++ b/src/net_processing.cpp @@ -865,7 +865,15 @@ void PeerLogicValidation::BlockChecked(const CBlock& block, const CValidationSta Misbehaving(it->second.first, nDoS); } } - else if (state.IsValid() && !IsInitialBlockDownload() && mapBlocksInFlight.count(hash) == mapBlocksInFlight.size()) { + // Check that: + // 1.
