From 1f592b045fb6b2788c595e573412aa93f3ebc850 Mon Sep 17 00:00:00 2001 From: Matt Corallo Date: Tue, 22 Jun 2021 01:33:44 +0000 Subject: [PATCH] Do not log_debug when we receive duplicate gossip messages We very often receive duplicate gossip messages, which now causes us to log at the DEBUG level, which is almost certainly not what a user wants. Instead, we add a new form of ErrorAction which causes us to only log at the TRACE level. --- lightning/src/ln/msgs.rs | 5 +++++ lightning/src/ln/peer_handler.rs | 19 ++++++++++++++----- lightning/src/routing/network_graph.rs | 8 ++++---- 3 files changed, 23 insertions(+), 9 deletions(-) diff --git a/lightning/src/ln/msgs.rs b/lightning/src/ln/msgs.rs index f02a47835..c45e2277f 100644 --- a/lightning/src/ln/msgs.rs +++ b/lightning/src/ln/msgs.rs @@ -38,6 +38,7 @@ use core::fmt::Debug; use std::io::Read; use util::events::MessageSendEventsProvider; +use util::logger; use util::ser::{Readable, Writeable, Writer, FixedLengthReader, HighZeroBytesDroppedVarInt}; use ln::{PaymentPreimage, PaymentHash, PaymentSecret}; @@ -688,7 +689,11 @@ pub enum ErrorAction { msg: Option }, /// The peer did something harmless that we weren't able to process, just log and ignore + // New code should *not* use this.
