There's not a ton of reason not to do this, and moving it to the macro removes some code.

Note that this feature bit does absolutely nothing. We signal it (as we already support channel type negotiation), but do not bother to look to see if peers support it, as we don't care - we simply look for the TLV entry and deduce if a peer supports channel type negotiation from that. The only behavioral change at all here is that we don't barf if a peer sets channel type negotiation to required via the feature bit (instead of failing the channel at open-time), but of course no implementations do this, and likely won't for some time (if ever - you can simply fail channels with unknown types later, and there's no reason to refuse connections, really).

With this, a payer can more simply deduce when a payment has failed and use that to remove payment state or finalize a payment failure. commit 0b3240ee6a6e1baeafaed9e766997098be588358 Author: Matt Corallo <[email protected]> Date: Fri Dec 3 19:57:37 2021 +0000 Add a variant to `PendingOutboundPayment` for retries-exceeded When a payer gives up trying to retry a payment, they don't know for sure what the current state of the event queue is. Specifically, they cannot be sure that there are not multiple additional `PaymentPathFailed` or even `PaymentSuccess` events pending which they will see later. Thus, they have a very hard time identifying whether a payment has truly failed (and informing the UI of that fact) or if it is still pending. See [1] for more information. In order to avoid this mess, we will resolve it here by having the payer give `ChannelManager` a bit more information - when they have given up on a payment - and using that to generate a `PaymentFailed` event when all paths have failed. This commit adds the neccessary storage and changes for the new state inside `ChannelManager` and a public method to mark a payment as failed, the next few commits will add the new `Event` and use the new features in our `PaymentRetrier`.

The only behavioral change at all here is that we don't barf if a peer sets channel type negotiation to required via the feature bit (instead of failing the channel at open-time), but of course no implementations do this, and likely won't for some time (if ever - you can simply fail channels with unknown types later, and there's no reason to refuse connections, really).

This would allow a race condition where we could receive a payment (including the counterparty revoking their broadcasted state!) and accept it without recourse as long as the ChannelMonitor receives the block first, the full commitment update dance occurs after the block is connected, and before the ChannelManager receives the block. Obviously this is an incredibly contrived race given the counterparty would be risking their full channel balance for it, but its worth fixing nonetheless as it makes the potential ChannelMonitor states simpler to reason about. The test in this commit also tests the behavior changed in the previous commit. commit aa5e5f967375eb31d8b0d0ed7f20ef31242693f7 Author: Matt Corallo <[email protected]> Date: Fri Jul 23 15:49:24 2021 +0000 Define public getters for all feature flags There's not a ton of reason not to do this, and moving it to the macro removes some code. commit 361639decf9c98ff43d228415e3cab5955e2b973 Author: Matt Corallo <[email protected]> Date: Mon Dec 6 00:12:35 2021 +0000 Remove OnionV2 parsing support OnionV2s don't (really) work on Tor anymore anyway, and the field is set for removal in the BOLTs [1].

This really, really, absolutely should have been a compile failure - the type (with methods called on it!) was ambiguous! Instead, rustc seems to have been defaulting to `Option<()>`, causing us to read zero of the eight bytes in the `user_payment_id` field, which returns an `Err(InvalidValue)` error as TLVs must always be read fully. This should likely be reported to rustc as its definitely a bug, but I cannot seem to cause the same error on any kinda of vaguely-minimized version of the same code.

To allow no-std users to provide a time source it was exposed as a trait as well. However, it seems somewhat unlikely that a no-std user is going to have a use for providing their own time source (otherwise they wouldn't be a no-std user), and likely they won't have a graph in memory either. `scoring::Time` as currently written is also exceptionally hard to write C bindings for - the C bindings trait mappings relies on the ability to construct trait implementations at runtime with function pointers (i.e. `dyn Trait`s). `scoring::Time`, on the other hand, is a supertrait of `core::ops::Sub` which requires a `sub` method which takes a type parameter and returns a type parameter. Both of which aren't practical in bindings, especially given the `Sub::Output` associated type is not bound by any trait bounds at all (implying we cannot simply map the `sub` function to return an opaque trait object). Thus, for simplicity, we here simply seal `scoring::Time` and make it effectively-private, ensuring the bindings don't need to bother with it. commit a173ded03f84193f8da14301e81fdec419c5e441 Author: Matt Corallo <[email protected]> Date: Mon Nov 22 03:27:17 2021 +0000 Make `Score : Writeable` in c_bindings and impl on `LockedScore` Ultimately we likely need to wrap the locked `Score` in a struct that exposes writeable somehow, but because all traits have to be fully concretized for C bindings we'll still need `Writeable` on all `Score` in order to expose `Writeable` on the locked score. Otherwise, we'll only have a `LockedScore` with a `Score` visible that only has the `Score` methods, never the original type. commit 937403ed780f63a8a48fe1939f9af23b12d04f9c Merge: ef86a3e2 4831de41 Author: Matt Corallo <[email protected]> Date: Wed Nov 24 16:31:32 2021 +0000 Merge pull request #1186 from TheBlueMatt/2021-11-fix-log-select Fix the `max_level_trace` feature commit 4831de41ec40f842148358592da8c1ded7e2d523 Author: Matt Corallo <[email protected]> Date: Tue Nov 23 23:03:34 2021 +0000 Test all log-limiting features in CI commit 31e592bedf0899dc425036d1518dd83fb0161609 Author: Matt Corallo <[email protected]> Date: Tue Nov 23 23:03:13 2021 +0000 Fix compilation with the max_level_trace feature commit d2ac683f4e6267b1ae8997a97b1c1dec1cd540c2 Author: Matt Corallo <[email protected]> Date: Tue Nov 16 20:55:10 2021 +0000 Add a comment describing `update_time_counter` and when its updated commit 391fbfbe1abbd011395542f5f0f96dbc57b8655e Author: Matt Corallo <[email protected]> Date: Sat Nov 13 01:54:54 2021 +0000 Re-broadcast our own gossip even if its same as the last broadcast Even if our gossip hasn't changed, we should be willing to re-broadcast it to our peers.

However, if a peer disconnects or reconnects, we may wish to generate `ChannelUpdate` updates in between new blocks. In such a case, we need to make sure the `timestamp` field is newer than any previous updates' `timestamp` fields, which we do here by simply incrementing it when the channel status is changed. As a side effect of this we have to update `test_background_processor` to ensure it eventually succeeds even if the serialization of the `ChannelManager` changes after the test begins. commit 74828d243567af448cec5f09eb2d6a8eeed3ca48 Author: Matt Corallo <[email protected]> Date: Sat Nov 13 00:27:05 2021 +0000 Separate ChannelAnnouncement and ChannelUpdate broadcast conditions When a `ChannelUpdate` message is generated for broadcast as a part of a `BroadcastChannelAnnouncement` event, it may be newer than our previous `ChannelUpdate` and need to be broadcast.

Instead, we split the broadcast of each message as well as the conditional so that we always attempt to handle each message and update our local graph state, then broadcast the message if its update was processed successfully. commit f69311ccff517f01211415461db666db22290232 Author: Matt Corallo <[email protected]> Date: Tue Nov 9 21:12:30 2021 +0000 Store holder channel reserve and max-htlc-in-flight explicitly Previously, `holder_selected_channel_reserve_satoshis` and `holder_max_htlc_value_in_flight_msat` were constant functions of the channel value satoshis.

We go ahead and do so here, in part as it will make testing different counterparty-selected channel reserve values easier. commit ef86a3e20952a96f7b646a9a4154aa5dc220147a Merge: 19191b45 13e4fd58 Author: Matt Corallo <[email protected]> Date: Tue Nov 23 20:46:38 2021 +0000 Merge pull request #1162 from TheBlueMatt/2021-11-fix-accept-chan-checks Correct initial commitment tx fee affordability checks on open commit 19191b450c8f07e7b703ec83eabaa0d268757bd7 Merge: 2b789578 2c4f16d5 Author: Matt Corallo <[email protected]> Date: Tue Nov 23 20:39:28 2021 +0000 Merge pull request #1178 from jkczyz/2021-11-payment-path-successful Generate PaymentPathSuccessful event for each path commit 2b78957888b86760bb16325a23302d9c979b5602 Merge: ba50dd57 530abc5e Author: Matt Corallo <[email protected]> Date: Tue Nov 23 19:37:09 2021 +0000 Merge pull request #1176 from lightning-signer/2021-11-htlc-anchors Add anchors support for HTLCs commit 2c4f16d5e39e6d4e90d1b9836cceaad11810fbaa Author: Jeffrey Czyz <[email protected]> Date: Thu Nov 18 16:24:14 2021 -0600 Generate PaymentPathSuccessful event for each path A single PaymentSent event is generated when a payment is fulfilled.

This avoids duplicate events when reconnecting to a peer. commit 530abc5efd96da693316f2c45c6169c1ee7064e6 Author: Ken Sedgwick <[email protected]> Date: Tue Nov 16 11:40:27 2021 -0800 Add test vectors for get_htlc_redeemscript wrt anchors commit 50d81220df0d1f73541f39863657ca9bde193afc Author: Ken Sedgwick <[email protected]> Date: Tue Nov 16 09:27:33 2021 -0800 Adjust HTLC_{SUCCESS,TIMEOUT}_TX_WEIGHT when anchors used commit 6c36e011a80cd3d02db8591fb9a19111dceecb86 Author: Ken Sedgwick <[email protected]> Date: Mon Nov 15 19:39:39 2021 -0800 Add anchor support to build_htlc_transaction commit c077f36b4b231b05b9c6bfadd5ef0c017b17eaa0 Author: Ken Sedgwick <[email protected]> Date: Mon Nov 15 18:50:57 2021 -0800 Increase visibility of anchor related methods commit 3efcbab5d42d5c2cd7d37ce18a8bcca211569bb8 Author: Ken Sedgwick <[email protected]> Date: Mon Nov 15 18:03:46 2021 -0800 Add anchor support to commitment HTLC outputs commit 016eb96fc7170bdbab238292d3cc9338c2a66eb9 Author: Matt Corallo <[email protected]> Date: Sun Nov 21 22:29:48 2021 +0000 Support `logger::Record` in C by String-ing the fmt::Arguments This adds a new (non-feature) cfg argument `c_bindings` which will be set when building C bindings. With this, we can (slightly) tweak behavior and API based on whether we are being built for Rust or C users. Ideally we'd never need this, but as long as we can keep the API consistent-enough to avoid material code drift, this gives us a cheap way of doing the "right" thing for both C and Rust when the two are in tension. We also move lightning-background-processor to support the same MSRV as the main lightning crate, instead of only lightning-net-tokio's MSRV. commit 13e4fd586ed0c8439dcada150c4fffa33fa67db9 Author: Matt Corallo <[email protected]> Date: Wed Nov 10 04:40:33 2021 +0000 Test fixed channel reserve checks on channel open commit 940ef05371221138a930b1afc1243cb1cdf63873 Author: Matt Corallo <[email protected]> Date: Wed Nov 10 01:36:26 2021 +0000 Correct initial commitment tx fee affordability checks on open Previously, we would reject inbound channels if the funder wasn't able to meet our channel reserve on their first commitment transaction only if they also failed to push enough to us for us to not meet their initial channel reserve as well. There's not a lot of reason to care about us meeting their reserve, however - its largely expected that they may not push enough to us in the initial open to meet it, and its not actually our problem if they don't. Further, we used our own fee, instead of the channel's actual fee, to calculate fee affordability of the initial commitment transaction. We resolve both issues here, rewriting the combined affordability check conditionals in inbound channel open handling and adding a fee affordability check for outbound channels as well. The prior code may have allowed a counterparty to start the channel with "no punishment" states - violating the reason for the reserve threshold. commit 1d30e06893ff6e19fbbe472ea74ef150f296cbfc Author: Matt Corallo <[email protected]> Date: Wed Nov 10 03:44:04 2021 +0000 Rewrite test_update_fee_that_funder_cannot_afford to avoid magic Instead of magic hard-coded constants, its better for tests to derive the values used so that they change if constants are changed and so that it is easier to re-derive constants in the future as needed. commit a33d3b98d7c6c4c786e53f5c904cb8620ec54e24 Author: Matt Corallo <[email protected]> Date: Mon Nov 15 23:22:08 2021 +0000 Make Channel::commit_tx_fee_msat static and take fee explicitly This may avoid risk of bugs in the future as it requires the caller to think about the fee being used, not just blindly use the current (committed) channel feerate. commit ba50dd57868a78d00ed1a3c7a9089cf39d3ca235 Merge: 22398853 c3c0e602 Author: Matt Corallo <[email protected]> Date: Mon Nov 22 22:45:51 2021 +0000 Merge pull request #1054 from ariard/2021-08-check-outbound-feerate Check for outbound feerate update affordability before sending commit 22398853c97966f42c709669fff3c63486d82993 Merge: 3cb3d18e 1180b633 Author: Matt Corallo <[email protected]> Date: Mon Nov 22 21:55:06 2021 +0000 Merge pull request #1168 from TheBlueMatt/2021-11-mpp-routing-fixes Fix MPP routefinding when we first collect 95% of payment value commit c3c0e60226c594f8a5b949b424e74078fd7a24ce Author: Antoine Riard <[email protected]> Date: Sun Nov 21 21:42:58 2021 -0500 Check outbound update_fee affordance incremented with holding cell HTLCs commit 1180b633b409029b45c5dbe31b698eaabc79f81a Author: Matt Corallo <[email protected]> Date: Mon Nov 8 03:17:34 2021 +0000 Fix MPP routefinding when we first collect 95% of payment value See comment in new test for more details. commit 3cb3d18e1d3a7ab8f1ecaa3923faaf7a6887b062 Merge: 58539b84 3b4b74bc Author: Matt Corallo <[email protected]> Date: Mon Nov 22 18:58:56 2021 +0000 Merge pull request #1145 from tnull/add_gossip_log_level Introduce GOSSIP log level to PeerHandler commit 3b4b74bc6643fbc87e252ad346263fdc22048e51 Author: Elias Rohrer <[email protected]> Date: Mon Nov 22 18:19:08 2021 +0100 Add a new log-level for gossip messages. commit 58539b8440e62dbfe54085949ab6246f4f93cba5 Merge: 1f170dba a4822e5b Author: Matt Corallo <[email protected]> Date: Mon Nov 22 16:40:37 2021 +0000 Merge pull request #1180 from valentinewallace/2021-11-remove-user-pmt-id Remove user_payment_id commit 1f170dba02c45b061116bbb5f1f82a329b6c9a89 Merge: 293e5f21 dea1310c Author: Matt Corallo <[email protected]> Date: Mon Nov 22 15:41:19 2021 +0000 Merge pull request #1182 from TheBlueMatt/2021-11-fix-txid-log Trivial Logging Fixes commit efd9ad22fc7d7c3ab131a7fc08b2aa1e1f46c1c0 Author: Antoine Riard <[email protected]> Date: Thu Nov 18 21:23:41 2021 -0500 Introduce CommitmentStats commit 40f48def109c61d6b569e03113820ee042837d1b Author: Antoine Riard <[email protected]> Date: Mon Sep 27 20:14:06 2021 -0400 Re-add `test_max_dust_htlc_exposure` commit dea1310c55171f03a23dc8d76b0f5cda666a93bf Author: Matt Corallo <[email protected]> Date: Sat Nov 20 22:49:11 2021 +0000 Ensure current channel state is logged for all channels on startup commit 0b072834ab92081bba4ec907b39f1aa78953016c Author: Matt Corallo <[email protected]> Date: Sat Nov 20 22:27:10 2021 +0000 Correct txid logging to reverse bytes.

Further, its incredibly awkward to have a `scorer` sub-module, but only have a single struct in it, with the relevant trait it is the only implementation of somewhere else. Not having `Score` in the `scorer` sub-module is further confusing because it's the only module anywhere that references scoring at all. commit 9bec35ddde1750359c47b0a83f820ab7287cfd03 Author: Matt Corallo <[email protected]> Date: Fri Nov 12 04:16:23 2021 +0000 Penalize large HTLCs relative to channels in default `Scorer` Sending HTLCs which are any greater than a very small fraction of the channel size tend to fail at a much higher rate.

This is obviously nonsense if the channel type is some future version - the client needs to fail to deserialize as it doesn't understand the channel's type. We adapt the serialization logic here to only write out the `ChannelTypeFeatures` field if it is something other than only-static-remote-key, and simply consider that "default" (as it is the only supported type today). Then, we write out the channel type as an even TLV, implying clients which do not understand it must fail to read the `Channel`. Note that we do not need to bother reserving the TLV type no longer written as it never appeared in a release (merged post-0.0.103). commit 4d6c26248d85abe9a3c8aeefe31b4ebafd3b5bee Merge: 4bb81ff5 5e998cce Author: Matt Corallo <[email protected]> Date: Tue Nov 16 16:18:20 2021 +0000 Merge pull request #1119 from TheBlueMatt/2021-10-less-aggressive-htlc-timeouts Be less aggressive in outbound HTLC CLTV timeout checks commit 5e998cce6ba4511df483cf893cd19b51a0ac0214 Author: Matt Corallo <[email protected]> Date: Wed Oct 13 04:19:13 2021 +0000 Be less aggressive in outbound HTLC CLTV timeout checks We currently assume our counterparty is naive and misconfigured and may force-close a channel to get an HTLC we just forwarded them.

Worse, this results in refusing to forward payments today, failing HTLCs for largely no reason. Instead, we keep a fairly conservative check, but not one which will fail HTLC forwarding spuriously - testing only that the HTLC doesn't expire for a few blocks from now.

Note that this feature bit does absolutely nothing. We signal it
(as we already support channel type negotiation), but do not bother
to look to see if peers support it, as we don't care - we simply
look for the TLV entry and deduce if a peer supports channel type
negotiation from that.
The only behavioral change at all here is that we don't barf if a
peer sets channel type negotiation to required via the feature bit
(instead of failing the channel at open-time), but of course no
implementations do this, and likely won't for some time (if ever -
you can simply fail channels with unknown types later, and there's
no reason to refuse connections, really).
