InvoiceBuilder is parameterized by a SigningPubkeyStrategy, either
ExplicitSigningPubkey and DerivedSigningPubkey. It also holds an
Option<KeyPair>, which may be None and Some for those strategies,
respectively. This leads to methods for InvoiceBuilder parameterized by
DerivedSigningPubkey needing to blindly unwrap the Option<KeyPair>.
Instead, have DerivedSigningPubkey wrap KeyPair.
The function used to sign BOLT 12 messages only takes a message digest.
This doesn't allow signers to independently verify the message before
signing nor does it allow them to derive the necessary signing keys, if
needed.
Introduce a TaggedHash wrapper for a message digest, which each unsigned
BOLT 12 message type constructs upon initialization. Change the signing
function to take AsRef<TaggedHash>, which each unsigned type implements.
This allows the signing function to take any unsigned message and obtain
its tagged hash.
This gives people more freedom with the channel monitors. For Mutiny
this would be nice for us to be able to create copies of them and pass
aorund in memory without having to serialize until we actually want to.

Small bugfix from Matt Corallo <git@bluematt.me>
This should at least marginally more aggressively target things
which are more likely to have changed in CI, making `ci-tests.sh`
more useful as a "default" script for developers to run locally.
While this is generally uneccessary as users set the `no-std` or
`std` features on the `lightning` crate directly, having this
allows `lightning-background-processor` to be built by itself
without extra dep lines. Specifically, the bindings are moving to
using the `-Z avoid-dev-deps` option, which now causes
`lightning-background-processor` to fail to build directly.
Previously, we barely gave any hints why we excluded certain hops during
pathfinding. Here, we introduce more verbose logging by a) accounting
how much candidates we ignored for which reasons and b) logging any
first/last/blinded hops we end up ignoring.
Fixes#1646.
As `RouteParameters` are not included anymore in
`Event::PaymentPathFailed` since 0.0.115, and we don't give value/payee
as immediate arguments to `find_route` anymore.
A channel's `short_channel_id` is currently only set when the funding
transaction is confirmed via `transactions_confirmed`, which might be
well after the channel initally becomes usable, e.g., in the 0conf case.
Previously we would panic due to a reachable `unwrap` when receiving a
counterparty's `announcement_signatures` message for a 0conf channel
pending confirmation on-chain.
Here we fix this bug by avoiding unsafe `unwrap`s and just erroring out
and ignoring the announcement_signatures message if the `short_channel_id`
hasn't been set yet.
While bindings should probably be able to figure out that this is
the same type as `Self`, for now we simply swap the type to make
the bindings generator have an easier go of it.
The bindings are being updated to consider all traits even if the
trait itself is no-export, which causes issues generating code
around the `Duration` impl here.
We missed one method that now cannot be bindings exported - the
`payment_paths` method, as it returns a slice of objects, which
cannot be supported in bindings.
In bindings we can't practically pass a mutable PSBT, and instead
need to pass an owned transaction and have the sign method return a
signed copy. We do this here for all build modes as its not a
material API change for Rust users.
This code was always effectively dead - we have a special
`MultiThreadedLockableScore` type which wraps a `Mutex` for
bindings users, so there's no need to implement any
bindings-specific scoring logic for them.
Given we build `InFlightHtlcs` per route-fetch call, there's no
reason to pass them out by reference rather than simply giving the
user the full object. This also allows them to tweak the in-flight
set before fetching a route.
We already hold them in a vec, so there's no cost to passing them
by ownership vs making it a slice. Further, this helps bindings as
we can't represent slices to non-pointers in a sensible way.
In bindings we can't practically pass a mutable transaction, and
instead need to pass an owned transaction and have the sign method
return a signed copy. We do this here for all build modes as the
API is roughly equivalent also to Rust users.
We introduce a `UnfundedChannelContext` which contains a counter for the
current age of an unfunded channel in timer ticks. This age is incremented
for every `ChannelManager::timer_tick_ocurred` and the unfunded channel
is removed if it exceeds `UNFUNDED_CHANNEL_AGE_LIMIT_TICKS`.
The value will not be persisted as unfunded channels themselves are not
persisted.
