Member Function Documentation

CheckForStaleTipAndEvictPeers()

virtual void PeerManager::CheckForStaleTipAndEvictPeers ( )

pure virtual

Evict extra outbound peers.

If we think our tip may be stale, connect to an extra outbound. Public for unit testing.

GetNodeStateStats()

virtual bool PeerManager::GetNodeStateStats ( NodeId  nodeid, CNodeStateStats &  stats  )

pure virtual

Get statistics from node state.

IgnoresIncomingTxs()

virtual bool PeerManager::IgnoresIncomingTxs ( )

pure virtual

Whether this node ignores txs received over p2p.

make()

std::unique_ptr< PeerManager > PeerManager::make ( const CChainParams &  chainparams, CConnman &  connman, CAddrMan &  addrman, BanMan *  banman, CScheduler &  scheduler, ChainstateManager &  chainman, CTxMemPool &  pool, bool  ignore_incoming_txs  )

Here is the caller graph for this function:

Misbehaving()

virtual void PeerManager::Misbehaving ( const NodeId  pnode, const int  howmuch, const std::string &  message  )

pure virtual

Increment peer's misbehavior score.

If the new value >= DISCOURAGEMENT_THRESHOLD, mark the node to be discouraged, meaning the peer might be disconnected and added to the discouragement filter. Public for unit testing.

ProcessMessage()

virtual void PeerManager::ProcessMessage ( CNode &  pfrom, const std::string &  msg_type, CDataStream &  vRecv, const std::chrono::microseconds  time_received, const std::atomic< bool > &  interruptMsgProc  )

pure virtual

Process a single message from a peer.

Public for fuzz testing

RelayTransaction()

virtual void PeerManager::RelayTransaction ( const uint256 &  txid, const uint256 &  wtxid  )

pure virtual

Relay transaction to all peers.

SendPings()

virtual void PeerManager::SendPings ( )

pure virtual

Send ping message to all peers.

SetBestHeight()

virtual void PeerManager::SetBestHeight ( int  height )

pure virtual

Set the best height.
