From af7e9b608d7a78dbb1a87a31a5b45c758f15c0ec Mon Sep 17 00:00:00 2001 From: Matt Corallo Date: Mon, 25 Jul 2022 18:08:44 +0000 Subject: [PATCH] Change `LowerBoundedFeeEstimator` fn name to make it hard to swap This change the method name on `LowerBoundedFeeEstimator` to further differentiate it from the generic `FeeEstimator` trait. --- lightning/src/chain/chaininterface.rs | 6 +++--- lightning/src/chain/package.rs | 6 +++--- lightning/src/ln/channel.rs | 10 +++++----- lightning/src/ln/channelmanager.rs | 4 ++-- 4 files changed, 13 insertions(+), 13 deletions(-) diff --git a/lightning/src/chain/chaininterface.rs b/lightning/src/chain/chaininterface.rs index 50570dfd..be86261f 100644 --- a/lightning/src/chain/chaininterface.rs +++ b/lightning/src/chain/chaininterface.rs @@ -72,7 +72,7 @@ impl LowerBoundedFeeEstimator where F::Target: FeeEstimator { LowerBoundedFeeEstimator(fee_estimator) } - pub fn get_est_sat_per_1000_weight(&self, confirmation_target: ConfirmationTarget) -> u32 { + pub fn bounded_sat_per_1000_weight(&self, confirmation_target: ConfirmationTarget) -> u32 { cmp::max( self.0.get_est_sat_per_1000_weight(confirmation_target), FEERATE_FLOOR_SATS_PER_KW, @@ -100,7 +100,7 @@ mod tests { let test_fee_estimator = &TestFeeEstimator { sat_per_kw }; let fee_estimator = LowerBoundedFeeEstimator::new(test_fee_estimator); - assert_eq!(fee_estimator.get_est_sat_per_1000_weight(ConfirmationTarget::Background), FEERATE_FLOOR_SATS_PER_KW); + assert_eq!(fee_estimator.bounded_sat_per_1000_weight(ConfirmationTarget::Background), FEERATE_FLOOR_SATS_PER_KW); } #[test] @@ -109,6 +109,6 @@ mod tests { let test_fee_estimator = &TestFeeEstimator { sat_per_kw }; let fee_estimator = LowerBoundedFeeEstimator::new(test_fee_estimator); - assert_eq!(fee_estimator.get_est_sat_per_1000_weight(ConfirmationTarget::Background), sat_per_kw); + assert_eq!(fee_estimator.bounded_sat_per_1000_weight(ConfirmationTarget::Background), sat_per_kw); } } diff --git a/lightning/src/chain/package.rs b/lightning/src/chain/package.rs index b0cfa9bf..30530303 100644 --- a/lightning/src/chain/package.rs +++ b/lightning/src/chain/package.rs @@ -778,13 +778,13 @@ fn compute_fee_from_spent_amounts(input_amounts: u64, predic where F::Target: FeeEstimator, L::Target: Logger, { - let mut updated_feerate = fee_estimator.get_est_sat_per_1000_weight(ConfirmationTarget::HighPriority) as u64; + let mut updated_feerate = fee_estimator.bounded_sat_per_1000_weight(ConfirmationTarget::HighPriority) as u64; let mut fee = updated_feerate * (predicted_weight as u64) / 1000; if input_amounts <= fee { - updated_feerate = fee_estimator.get_est_sat_per_1000_weight(ConfirmationTarget::Normal) as u64; + updated_feerate = fee_estimator.bounded_sat_per_1000_weight(ConfirmationTarget::Normal) as u64; fee = updated_feerate * (predicted_weight as u64) / 1000; if input_amounts <= fee { - updated_feerate = fee_estimator.get_est_sat_per_1000_weight(ConfirmationTarget::Background) as u64; + updated_feerate = fee_estimator.bounded_sat_per_1000_weight(ConfirmationTarget::Background) as u64; fee = updated_feerate * (predicted_weight as u64) / 1000; if input_amounts <= fee { log_error!(logger, "Failed to generate an on-chain punishment tx as even low priority fee ({} sat) was more than the entire claim balance ({} sat)", diff --git a/lightning/src/ln/channel.rs b/lightning/src/ln/channel.rs index f612cb97..b698a919 100644 --- a/lightning/src/ln/channel.rs +++ b/lightning/src/ln/channel.rs @@ -917,7 +917,7 @@ impl Channel { return Err(APIError::APIMisuseError { err: format!("Holder selected channel reserve below implemention limit dust_limit_satoshis {}", holder_selected_channel_reserve_satoshis) }); } - let feerate = fee_estimator.get_est_sat_per_1000_weight(ConfirmationTarget::Normal); + let feerate = fee_estimator.bounded_sat_per_1000_weight(ConfirmationTarget::Normal); let value_to_self_msat = channel_value_satoshis * 1000 - push_msat; let commitment_tx_fee = Self::commit_tx_fee_msat(feerate, MIN_AFFORDABLE_HTLC_COUNT, opt_anchors); @@ -1064,11 +1064,11 @@ impl Channel { // We generally don't care too much if they set the feerate to something very high, but it // could result in the channel being useless due to everything being dust. let upper_limit = cmp::max(250 * 25, - fee_estimator.get_est_sat_per_1000_weight(ConfirmationTarget::HighPriority) as u64 * 10); + fee_estimator.bounded_sat_per_1000_weight(ConfirmationTarget::HighPriority) as u64 * 10); if feerate_per_kw as u64 > upper_limit { return Err(ChannelError::Close(format!("Peer's feerate much too high.
