This reverts commit 85eb8145fb.
Logging here can be overly verbose and moreover in case of event
handling failure, we loop back without any added delay.
ChannelManager is parameterized by a Router, which must also implement
MessageRouter. Instead, add a MessageRouter parameter such that the
Router and MessageRouter traits can be de-coupled. This simplifies using
something other than DefaultMessageRouter, which DefaultRouter currently
delegates to.
Currently we don't have any visibility if BackgroundProcessor
takes considerably more of time to process events, adding logs
to help debug such issues.
In order to maintain interface consistency, we refactor all message
handler interfaces to take `PublicKey` rather than `&PublicKey`, as the
difference in efficiency should be negigible and the former is easier to
handle in binding languages.
Over time, we also want to move (no pun intended) towards all messaging
interfaces using move semantics, so dropping the reference for
`PublicKey` is the first step in this direction.
Now that we don't have to have everything in our entire ecosystem
use the same `std`/`no-std` feature combinations we should start by
untangling our own features a bit.
This takes the first step by removing the `no-std` feature entirely
from the `lightning-background-processor` crate and removing most
feature implications on dependencies from the remaining `std`
feature.
It also addresses a CI oversight where we were not testing
`lightning-background-processor` without the `std` feature in CI at
all.
Version 0.32.2 of `rust-bitcoin` deprecates a number of methods that
are commonly used in this project, most visibly `txid()`, which is
now called `compute_txid()`. This resulted in a lot of warnings, and
this commit is part of a series that seeks to address that.
The `rust-bitcoin` project is working towards making the public API
separate from the directory structure; eventually the
`bitcoin::blockdata` will go away, to make maintenance easier here stop
using the `blockdata` module.
Do not run the formatter, so as to make review easier. This patch was
created mechanically using:
search-and-replace bitcoin::blockdata bitcoin
and having defined
```bash
search-and-replace () {
if (($# != 2))
then
echo "Usage: $0 <this> <that>"
return
fi
local this="$1"
local that="$2"
for file in $(git grep -l "$this")
do
perl -pi -e "s/$this/$that/g" "$file"
done
}
```
`ChannelId` is just a 32-byte array, so there's not a lot of value
in passing it by reference to `funding_transaction_generated`,
which we fix here.
This is also nice for bindings as languages like Java can better
analyze whether the `ChannelManager` ends up with a reference to
the `ChannelId`.
Previously, we would require our users to handle all events
successfully inline or panic will trying to do so. If they would exit
the `EventHandler` any other way we'd forget about the event and
wouldn't replay them after restart.
Here, we implement fallible event handling, allowing the user to return
`Err(())` which signals to our event providers they should abort event
processing and replay any unhandled events later (i.e., in the next
invocation).
This uses the newly introduced conditional configuration checks that are
now configurable withint Cargo (beta).
This allows us to get rid of our custom python script that checks for
expected features and cfgs.
This does introduce a warning regarding the unknown lint in Cargo
versions prior to the current beta, but since these are not rustc errors,
they won't break any builds with the "-D warnings" RUSTFLAG.
Moving to this lint actually exposed the "strict" feature not being
present in the lightning-invoice crate, as our python script didnt
correctly parse the cfg_attr where it appeared.
Add a trait for handling async payments messages to OnionMessenger. This allows
users to either provide their own custom handling for async payments messages
or rely on a version provided by LDK.
When `OnionMessenger` first developed a timer and events interface,
we accessed the `OnionMessenger` indirectly via the `PeerManager`.
While this is a fairly awkward interface, it avoided a large pile
of generics on the background processor interfaces. However, since
we now have an `AOnionMessenger` trait, this concern is no longer
significant. Further, because we now want to use the built-in
`OnionMessenger` async event processing method, we really need a
direct referene to the `OnionMessenger` in the background
processor, which we add here optionally.
The `PaymentHash`, `PaymentSecret`, `PaymentPreimage`, and
`ChannelId` types are all small wrappers around `[u8; 32]` and are
used throughout the codebase but were defined in the top-level
`ln/mod.rs` file and the relatively sparsely-populated
`ln/channel_id.rs` file.
Here we move them to a common `types` module and go ahead and
update all our in-crate `use` statements to refer to the new
module for bindings. We do, however, leave a `pub use` alias for
the old paths to avoid upgrade hassle for users.
In this commit i added additional parameter `error_message` to
`force_close_sending_error`. This parameter will allow users to
configure error message and send to peers during the force closing
of channel.I have also updated the tests for this updated function.
.. we simply check that the `OutputSweeper` generates a spending tx and
that the `TrackedSpendableOutput` is pruned once it reaches
`ANTI_REORG_DELAY`.
Replace instance of ChannelManager in BackgroundProcessor and in
Persister with AChannelManager. This reduces the number of type
parameters need in those types, which would need to be repeated in an
async version of Persister.
When an `std::future::Future` is `poll()`ed, we're only supposed to
use the latest `Waker` provided. However, we currently push an
`StdWaker` onto our callback list every time `poll` is called,
waking every `Waker` but also using more and more memory until the
`Future` itself is woken.
Here we fix this by removing any `StdWaker`s stored for a given
`Future` when it is `drop`ped or prior to pushing a new `StdWaker`
onto the list when `poll`ed.
Sadly, the introduction of a `Drop` impl for `Future` means we
can't trivially destructure the struct any longer, causing a few
methods to need to take `Future`s by reference rather than
ownership and `clone` a few `Arc`s.
Fixes#2874
