From ca8549d2bd32f17f8b69d1edbe3f2976fba504b4 Mon Sep 17 00:00:00 2001 From: Gregory Maxwell Date: Tue, 22 Nov 2016 02:50:24 +0000 Subject: [PATCH] Always drop the least preferred HB peer when adding a new one. When a BIP152 HB-mode peer is in the least preferred position and disconnects, they will not be by ForNode on the next loop. They will continue to sit in that position and prevent deactivating HB mode for peers that are still connected. There is no reason for them to stay in the list if already gone, so drop the first element unconditionally if there are too many. Fixes issue #9163. --- src/main.cpp | 5 ++--- 1 file changed, 2 insertions(+), 3 deletions(-) diff --git a/src/main.cpp b/src/main.cpp index 4293a6bebf..dd57153eae 100644 --- a/src/main.cpp +++ b/src/main.cpp @@ -529,12 +529,11 @@ void MaybeSetPeerAsAnnouncingHeaderAndIDs(const CNodeState* nodestate, CNode* pf if (lNodesAnnouncingHeaderAndIDs.size() >= 3) { // As per BIP152, we only get 3 of our peers to announce // blocks using compact encodings. - bool found = connman.ForNode(lNodesAnnouncingHeaderAndIDs.front(), [&connman, fAnnounceUsingCMPCTBLOCK, nCMPCTBLOCKVersion](CNode* pnodeStop){ + connman.ForNode(lNodesAnnouncingHeaderAndIDs.front(), [&connman, fAnnounceUsingCMPCTBLOCK, nCMPCTBLOCKVersion](CNode* pnodeStop){ connman.PushMessage(pnodeStop, NetMsgType::SENDCMPCT, fAnnounceUsingCMPCTBLOCK, nCMPCTBLOCKVersion); return true; }); - if(found) - lNodesAnnouncingHeaderAndIDs.pop_front(); + lNodesAnnouncingHeaderAndIDs.pop_front(); } fAnnounceUsingCMPCTBLOCK = true; connman.PushMessage(pfrom, NetMsgType::SENDCMPCT, fAnnounceUsingCMPCTBLOCK, nCMPCTBLOCKVersion);
