To keep diff reasonable it did so in ChannelMonitor after the LocalCommitmentTransaction had been constructed and passed over the wall, but there's little reason to do so - we should just be constructing them with the data from the start, filled in by Channel. This cleans up some internal interfaces a bit, slightly reduces some data duplication and moves us one step forward to exposing the guts of LocalCommitmentTransaction publicly in a sensible way. ---

Delay creating outbound ChannelMonitor until funding_signed rcpt Previously, we created the initial ChannelMonitor on outbound channels when we generated the funding_created message. This was somewhat unnecessary as, at that time, we hadn't yet received clearance to broadcast our initial funding transaction, and thus there should never be any use for a ChannelMonitor. It also complicated ChannelMonitor a bit as, at this point, we didn't have an initial local commitment transaction. By moving the creation of the initial ChannelMonitor to when we receive our counterparty's funding_signed, we can ensure that any ChannelMonitor will always have both a latest remote commitment tx and a latest local commitment tx for broadcast. This also fixes a strange API where we would close a channel unceremoniously on peer-disconnection if we hadn't yet received the funding_signed, but we'd already have a ChannelMonitor for that channel. While it isn't strictly a bug (some potential DoS issues aside), it is strange that these two definitions of a channel being open were not in sync. --- lightning/src/ln/chanmon_update_fail_tests.rs | 59 +++------- lightning/src/ln/channel.rs | 103 ++++++++---------- lightning/src/ln/channelmanager.rs | 35 +----- lightning/src/ln/functional_test_utils.rs | 29 ++--- lightning/src/ln/functional_tests.rs | 9 +- 5 files changed, 81 insertions(+), 154 deletions(-) diff --git a/lightning/src/ln/chanmon_update_fail_tests.rs b/lightning/src/ln/chanmon_update_fail_tests.rs index 71e4d376f7d..5d8c47377c7 100644 --- a/lightning/src/ln/chanmon_update_fail_tests.rs +++ b/lightning/src/ln/chanmon_update_fail_tests.rs @@ -1629,12 +1629,9 @@ fn monitor_update_claim_fail_no_response() { claim_payment(&nodes[0], &[&nodes[1]], payment_preimage_2, 1_000_000);
