f06b3b2d2bd179fe72742a2247ef614606092d07 Mon Sep 17 00:00:00 2001 From: Suphanat Chunhapanya Date: Thu, 29 Feb 2024 10:19:01 +0700 Subject: [PATCH 04/31] Send IDONTWANT right before validation step Most importantly, this commit adds a new method called PreValidation to the interface PubSubRouter, which will be called right before validating the gossipsub message. In GossipSubRouter, PreValidation will send the IDONTWANT controll messages to all the mesh peers of the topics of the received messages. --- comm.go | 12 +++++--- floodsub.go | 2 ++ gossipsub.go | 69 +++++++++++++++++++++++++++++------------- gossipsub_spam_test.go | 6 ++-- gossipsub_test.go | 2 +- pubsub.go | 38 +++++++++++++++++------ randomsub.go | 2 ++ 7 files changed, 92 insertions(+), 39 deletions(-) diff --git a/comm.go b/comm.go index d96e1c2a..1c014533 100644 --- a/comm.go +++ b/comm.go @@ -205,15 +205,17 @@ func rpcWithControl(msgs []*pb.Message, ihave []*pb.ControlIHave, iwant []*pb.ControlIWant, graft []*pb.ControlGraft, - prune []*pb.ControlPrune) *RPC { + prune []*pb.ControlPrune, + idontwant []*pb.ControlIDontWant) *RPC { return &RPC{ RPC: pb.RPC{ Publish: msgs, Control: &pb.ControlMessage{ - Ihave: ihave, - Iwant: iwant, - Graft: graft, - Prune: prune, + Ihave: ihave, + Iwant: iwant, + Graft: graft, + Prune: prune, + Idontwant: idontwant, }, }, } diff --git a/floodsub.go b/floodsub.go index fd7e6b49..45b3fdee 100644 --- a/floodsub.go +++ b/floodsub.go @@ -71,6 +71,8 @@ func (fs *FloodSubRouter) AcceptFrom(peer.ID) AcceptStatus { return AcceptAll } +func (fs *FloodSubRouter) PreValidation([]*Message) {} + func (fs *FloodSubRouter) HandleRPC(rpc *RPC) {} func (fs *FloodSubRouter) Publish(msg *Message) { diff --git a/gossipsub.go b/gossipsub.go index 50c5bca7..3be8dbe8 100644 --- a/gossipsub.go +++ b/gossipsub.go @@ -663,6 +663,27 @@ func (gs *GossipSubRouter) AcceptFrom(p peer.ID) AcceptStatus { return gs.gate.AcceptFrom(p) } +// PreValidation sends the IDONTWANT control messages to all the mesh +// peers.
