From 65e37fdc2909d9c8bb86ca4872725f9175aefd99 Mon Sep 17 00:00:00 2001 From: Matt Corallo Date: Sun, 3 Dec 2023 20:03:51 +0000 Subject: [PATCH] Ensure `ChannelMonitor` `Logger`s are always wrapped with metadata In order to ensure log lines generated by `ChannelMonitor` always have a counterparty and channel ID entry, this consistently wraps `Logger`s in a decorator in all `pub(X)` `ChannelMonitor` functions, removing `pub` markings on `ChannelMonitorImpl` methods that aren't actually publicly reachable anyway. This also lets us clean up the `Logger` types in various `ChannelMonitor` methods. --- lightning/src/chain/chainmonitor.rs | 19 ++-- lightning/src/chain/channelmonitor.rs | 158 +++++++++++++++----------- lightning/src/chain/onchaintx.rs | 27 ++--- lightning/src/chain/package.rs | 20 ++-- 4 files changed, 119 insertions(+), 105 deletions(-) diff --git a/lightning/src/chain/chainmonitor.rs b/lightning/src/chain/chainmonitor.rs index 39fa3a23..8c7bafe3 100644 --- a/lightning/src/chain/chainmonitor.rs +++ b/lightning/src/chain/chainmonitor.rs @@ -620,9 +620,8 @@ where C::Target: chain::Filter, pub fn rebroadcast_pending_claims(&self) { let monitors = self.monitors.read().unwrap();
