TxRequestTracker::ReceivedInv

Synopsis

Declared in <txrequest.h>

void
ReceivedInv(
    NodeId peer,
    GenTxid const& gtxid,
    bool preferred,
    std::chrono::microseconds reqtime);

Description

Does nothing if one already exists for that (txhash, peer) combination (whether it's CANDIDATE, REQUESTED, or COMPLETED). Note that the txid/wtxid property is ignored for determining uniqueness, so if an announcement is added for a wtxid H, while one for txid H from the same peer already exists, it will be ignored. This is harmless as the txhashes being equal implies it is a non-segwit transaction, so it doesn't matter how it is fetched. The new announcement is given the specified preferred and reqtime values, and takes its is_wtxid from the specified gtxid.

Parameters

Name	Description
peer	Peer that announced the transaction.
gtxid	Announced txid or wtxid, which also carries the is_wtxid flag.
preferred	Whether the announcement comes from a preferred peer.
reqtime	Earliest time the transaction may be requested from this peer.
