We've only ever made macaroons with the v2 versions, so we should
explicitly reject those that aren't actually v2. We add a basic test
along the way, and also add a similar check for the version encoded in
the macaroon ID.
* sweep: use longer variable name for clarity in `addToState`
* sweeper: add more docs and debug logs
* sweep: prioritize smaller inputs when adding wallet UTXOs
This commit sorts wallet UTXOs by their values when using them for
sweeping inputs. This way we'd avoid locking large UTXOs when sweeping
inputs and also provide an opportunity to aggregate wallet UTXOs.
* contractcourt+itest: relax anchor sweeping for CPFP purpose
This commit changes from always sweeping anchor for a local force close
to only do so when there is an actual time pressure. After this change,
a forced anchor sweeping will only be attempted when the deadline is
less than 144 blocks.
* docs: update release notes
* itest: update test `testMultiHopHtlcLocalChainClaim` to skip CPFP
Since we now only perform CPFP when both the fee rate is higher and the
deadline is less than 144, we need to update the test to reflect that
Bob will not CPFP the force close tx for the channle Alice->Bob.
* itest: fix `testMultiHopRemoteForceCloseOnChainHtlcTimeout`
* itest: update related tests to reflect anchor sweeping
This commit updates all related tests to reflect the latest anchor
sweeping behavior. Previously, anchor sweeping is always attempted as
CPFP when a force close is broadcast, while now it only happens when the
deadline is less than 144. For non-CPFP purpose sweeping, it will happen
after one block is mined after the force close transaction is confirmed
as the anchor will be resent to the sweeper with a floor fee rate, hence
making it economical to sweep.
* multi: extend InvoiceDB methods with a context argument
This commit adds a context to InvoiceDB's methods. Along this refactor
we also extend InvoiceRegistry methods with contexts where it makes
sense. This change is essential to be able to provide kvdb and sqldb
implementations for InvoiceDB.
* channeldb: restrict invoice tests to only use an InvoiceDB instance
* docs: update release notes for 0.18.0
* htlcswitch/hop: use InvalidOnionVersion for replayed packets
The link will send an update_fail_malformed_htlc, so we need to set
the BADONION bit. Since there isn't a replay-specific error, we
set the failure code to InvalidOnionVersion which has the BADONION bit.
* release-notes: update for 0.17.1
* Add instructions to generate type hints
Use mypy to generate .pyi files as well. These files are useful for type hinting in IDEs.
* Update python.md
fix lines that got swapped in copy-paste
* remove mypy
mypy is not a dependency
In this commit, we modify the incoming contest resolver to use a
concurrent queue. This is meant to ensure that the invoice registry
subscription loop never blocks. This change is meant to be minimal and
implements option `5` as outlined here:
https://github.com/lightningnetwork/lnd/issues/8023.
With this change, the inner loop of the subscription dispatch method in
the invoice registry will no longer block, as the concurrent queue uses
a fixed buffer of a queue, then overflows into another queue when that
gets full.

In this commit, we add the ability to obtain blocking and mutex
profiles. The blocking profile will show which goroutines are
consistently blocked on synchronization primitives like channels, or
I/O. The mutex profile will show which mutexes are very contested.
The blocking profile can be enabled with a new arg: `--blockingprofile`.
The mutex profile can be enabled with a new arg: `--mutexprofile`. These
are both ignored if the profile port isn't set.
Activating these profiles requires the caller to pass in a sampling
rate. For now I've set it just to `1` to test things out. Unfortunately
documentation is rather scarce, so there aren't any good guides re what
these values should be set to. AFAICT, these add more overhead than the
other prowling options, so they shouldn't necessarily be enabled
persistently in production.
In this commit, we update the set of protos to accept the local secret
nonces over RPC. This is actually a 97 byte value, as it includes the
two 32 byte nonces, as well as the 33 byte value of the public key of
the signer.
This is needed in order to be able to open taproot channels over the RPC
interface.
In this commit, we increase the max message size for the ws proxy. We
have a similar setting for the normal gRPC server which was tuned to be
able to support decoding `GetNetworkInfo` as the channel graph got
larger. We keep the default buffer size of 64 KB, but allow that to be
expanded to up to 4 MB (current value) to decode larger messages.
One alternative would be to modify the `Split` function to break up
larger lines into smaller ones. We'd need to double check that the
libraries at a higher level of abstraction can handle the chunks. The
scan function would look something like:
```go
splitFunc := func(data []byte, eof bool) (int, []byte, error) {
if len(data) >= chunkSize {
return chunkSize, data[:chunkSize], nil
}
return bufio.ScanLines(data, eof))
}
scanner.Split(splitFunc)
```
In this commit, update the start up logic to gracefully handle a
seemingly rare case. In this case, a peer detects local data loss with a
set of active HTLCs. These HTLCs then eventually expire (they may or may
not actually "exist"), causing a force close decision. Before this PR,
this attempt would fail with a fatal error that can impede start up.
To better handle such a scenario, we'll now catch the error when we fail
to force close due to entering the DLP and instead terminate the state
machine at the broadcast state. When a commitment transaction eventually
confirms, we'll play it as normal.
