Member Function Documentation

BlockChecked()

void PeerLogicValidation::BlockChecked ( const CBlock &  block, const CValidationState &  state  )

overridevirtual

Overridden from CValidationInterface.

Handle invalid block rejection and consequent peer banning, maintain which peers announce compact blocks.

Reimplemented from CValidationInterface.

BlockConnected()

void PeerLogicValidation::BlockConnected ( const std::shared_ptr< const CBlock > &  pblock, const CBlockIndex *  pindex, const std::vector< CTransactionRef > &  vtxConflicted  )

overridevirtual

Overridden from CValidationInterface.

Evict orphan txn pool entries (EraseOrphanTx) based on a newly connected block. Also save the time of the last tip update.

Reimplemented from CValidationInterface.

CheckForStaleTipAndEvictPeers()

void PeerLogicValidation::CheckForStaleTipAndEvictPeers

(

const Consensus::Params &

consensusParams

)

Evict extra outbound peers. If we think our tip may be stale, connect to an extra outbound

ConsiderEviction()

void PeerLogicValidation::ConsiderEviction	(	CNode *	pto,
		int64_t	time_in_seconds
	)

Consider evicting an outbound peer based on the amount of time they've been behind our tip

EvictExtraOutboundPeers()

void PeerLogicValidation::EvictExtraOutboundPeers

(

int64_t

time_in_seconds

)

If we have extra outbound peers, try to disconnect the one with the oldest block announcement

FinalizeNode()

void PeerLogicValidation::FinalizeNode ( NodeId  nodeid, bool &  fUpdateConnectionTime  )

overridevirtual

Handle removal of a peer by updating various state and removing it from mapNodeState

Implements NetEventsInterface.

InitializeNode()

void PeerLogicValidation::InitializeNode ( CNode *  pnode )

overridevirtual

Initialize a peer by adding it to mapNodeState and pushing a message requesting its version

Implements NetEventsInterface.

NewPoWValidBlock()

void PeerLogicValidation::NewPoWValidBlock ( const CBlockIndex *  pindex, const std::shared_ptr< const CBlock > &  pblock  )

overridevirtual

Overridden from CValidationInterface.

Maintain state about the best-seen block and fast-announce a compact block to compatible peers.

Reimplemented from CValidationInterface.

ProcessMessages()

bool PeerLogicValidation::ProcessMessages ( CNode *  pfrom, std::atomic< bool > &  interrupt  )

overridevirtual

Process protocol messages received from a given node

Parameters

[in]	pfrom	The node which we have received messages from.
[in]	interrupt	Interrupt condition for processing threads

Implements NetEventsInterface.

SendMessages()

bool PeerLogicValidation::SendMessages ( CNode *  pto ) -> cs_sendProcessing)

overridevirtual

Send queued protocol messages to be sent to a give node.

Parameters

[in]

pto

The node which we are sending messages to.

Returns

True if there is more work to be done

Implements NetEventsInterface.

SendRejectsAndCheckIfBanned()

bool PeerLogicValidation::SendRejectsAndCheckIfBanned ( CNode *  pnode, bool  enable_bip61  )

private

UpdatedBlockTip()

void PeerLogicValidation::UpdatedBlockTip ( const CBlockIndex *  pindexNew, const CBlockIndex *  pindexFork, bool  fInitialDownload  )

overridevirtual

Overridden from CValidationInterface.

Update our best height and announce any block hashes which weren't previously in ChainActive() to our peers.

Reimplemented from CValidationInterface.
