From: Antoine Riard Date: Thu, 30 Apr 2020 01:22:28 +0000 (-0400) Subject: Rename their_to_self_delay as on_local_tx_csv X-Git-Url: http://git.bitcoin.ninja/?a=commitdiff_plain;h=53884e3e55d0a205304c2e0e00a35185bd558a56;p=rust-lightning Rename their_to_self_delay as on_local_tx_csv on_remote_tx_csv is the CSV delay encumbering remote transactions revokable outputs as required by local. on_local_tx_csv is the CSV delay encumbering local transactions revokable outputs as required by remote. Local/remote is here defined from a code processing viewpoint, process running this code is "local". --- diff --git a/lightning/src/ln/channelmonitor.rs b/lightning/src/ln/channelmonitor.rs index 0a8c4bd46..f547bcc23 100644 --- a/lightning/src/ln/channelmonitor.rs +++ b/lightning/src/ln/channelmonitor.rs @@ -743,7 +743,7 @@ pub struct ChannelMonitor { // first is the idx of the first of the two revocation points their_cur_revocation_points: Option<(u64, PublicKey, Option)>, - their_to_self_delay: u16, + on_local_tx_csv: u16, commitment_secrets: CounterpartyCommitmentSecrets, remote_claimable_outpoints: HashMap>)>>, @@ -832,7 +832,7 @@ impl PartialEq for ChannelMonitor { self.funding_redeemscript != other.funding_redeemscript || self.channel_value_satoshis != other.channel_value_satoshis || self.their_cur_revocation_points != other.their_cur_revocation_points || - self.their_to_self_delay != other.their_to_self_delay || + self.on_local_tx_csv != other.on_local_tx_csv || self.commitment_secrets != other.commitment_secrets || self.remote_claimable_outpoints != other.remote_claimable_outpoints || self.remote_commitment_txn_on_chain != other.remote_commitment_txn_on_chain || @@ -927,7 +927,7 @@ impl ChannelMonitor { }, } - writer.write_all(&byte_utils::be16_to_array(self.their_to_self_delay))?; + writer.write_all(&byte_utils::be16_to_array(self.on_local_tx_csv))?; self.commitment_secrets.write(writer)?; @@ -1060,7 +1060,7 @@ impl ChannelMonitor { pub(super) fn new(keys: ChanSigner, shutdown_pubkey: &PublicKey, on_remote_tx_csv: u16, destination_script: &Script, funding_info: (OutPoint, Script), remote_htlc_base_key: &PublicKey, remote_delayed_payment_base_key: &PublicKey, - their_to_self_delay: u16, funding_redeemscript: Script, channel_value_satoshis: u64, + on_local_tx_csv: u16, funding_redeemscript: Script, channel_value_satoshis: u64, commitment_transaction_number_obscure_factor: u64, initial_local_commitment_tx: LocalCommitmentTransaction, logger: Arc) -> ChannelMonitor { @@ -1073,7 +1073,7 @@ impl ChannelMonitor { let remote_tx_cache = RemoteTxCache { remote_delayed_payment_base_key: *remote_delayed_payment_base_key, remote_htlc_base_key: *remote_htlc_base_key, on_remote_tx_csv, per_htlc: HashMap::new() }; - let mut onchain_tx_handler = OnchainTxHandler::new(destination_script.clone(), keys.clone(), their_to_self_delay, logger.clone()); + let mut onchain_tx_handler = OnchainTxHandler::new(destination_script.clone(), keys.clone(), on_local_tx_csv, logger.clone()); let local_tx_sequence = initial_local_commitment_tx.unsigned_tx.input[0].sequence as u64; let local_tx_locktime = initial_local_commitment_tx.unsigned_tx.lock_time as u64; @@ -1113,7 +1113,7 @@ impl ChannelMonitor { channel_value_satoshis: channel_value_satoshis, their_cur_revocation_points: None, - their_to_self_delay, + on_local_tx_csv, commitment_secrets: CounterpartyCommitmentSecrets::new(), remote_claimable_outpoints: HashMap::new(), @@ -1246,7 +1246,7 @@ impl ChannelMonitor { /// monitor watches for timeouts and may broadcast it if we approach such a timeout.
