The `log.go` file of each subserver is a copy and paste of the others.
All of them have the same typo, an extra space in a comment, and the
the definition of a function not used anywhere.
Was discovered in a race unit test in lightning node connect that uses
the websocket proxy to connect to the hashmail server on the client
side.
By not shadowing the err variable we end up reading and writing to the
same variable from two different goroutines, which causes the data race.
Because Taproot key spend only spends don't allow us to re-construct the
spent pkScript from the witness alone, we cannot support registering
spend notifications for v1 pkScripts only. We instead require the
outpoint to be specified. This commit makes it possible to only match by
outpoint and also adds an itest for it.
To help debug remote signing issues, it's helpful to get the raw PSBT
that failed to be parsed. This is necessary since serializing an invalid
PSBT is allowed and the checks only fail when trying to de-serialize
such an invalid packet.
In this commit, we add a new field to the WalletBalance call that
permits users to account for the set of outputs that may be locked due
to a pending transaction. Without this field any time users locked
outputs for things like PSBT signing, then they disappear from the
WalletBalance call, which may cause a panic.
In this commit we move the tracking of the outstanding intercepted htlcs
to InterceptableSwitch. This is a preparation for making the htlc
interceptor required.
Required interception involves tracking outstanding htlcs across
multiple grpc client sessions. The per-session routerrpc
forwardInterceptor object is therefore no longer the best place for
that.
This commit was previously split into the following parts to ease
review:
- 2d746f68: replace imports
- 4008f0fd: use ecdsa.Signature
- 849e33d1: remove btcec.S256()
- b8f6ebbd: use v2 library correctly
- fa80bca9: bump go modules
Previously, we'd always add up to the maximum number of hop hints
(and beyond!) when selecting hop hints in our first pass. This
change updates hop hint selection to always stick to our hop hint
limit, and to the "hop hint factor" that we scale our invoices by.
This change will result in selecting fewer channels in our first
pass if their total inbound capacity reaches our hop hint factor.
This prevents us from revealing as many private channels as
before, but has the downside of providing fewer options for
payers.
In this commit, we increase the legacy fee limit threshold (the amount
below which we'll allow 100% of funds to go to fees for the non-v2 RPC
calls) from 50 sats to 1k sats.
The API doc generator failed after merging #6149 because of the `lncli
importgraph` tag in the proto file.
We could also fix the API doc generator by adding the "dev" build tag,
but not including any dev only features in the API docs is probably the
preferred path.
Update SelectHopHints to return a set of hop hints that can be
converted to route hints / functional options by the caller. This
change allows external code to call SelectHopHints to get a set of
route hints and use them as it likes, rather than limiting the
return value to functional options for invoice creation.
When updating the channel routing policy, we encounter an inaccurate
precision error when calculating the routing fee. The issue stems from
the way the IEEE 754 standard works.
The solution here is to add a uint64 parameter (as mentioned in the
issue) and keep the float64 fee_rate parameter but rounding the product
of the base and fee rate.
This commits adds the devrpc package which implements a subserver that
adds clean separation for RPC calls useful for development and
debugging. This subserver is only compiled in if the dev tag is set.
Furthermore the commit adds the devrpc.ImportGraph call which can
import a graph dump obtained from another node by calling DescribeGraph.
Since the graph dump does not include the auth proofs, the imported
channels will be considered private.
This commit adds the `force` flag to the `XImportMissionControl` RPC
which allows skipping rules around the pair import except for what is
mandatory to make values meaningful. This can be useful for when clients
would like to forcibly override MC state in order to manipulate routing
results.
We use SignOutputRaw which expects a witness script being set, even for
P2WKH. There is a special case in SignOutputRaw for the case where the
script is a p2wkh script, then the input script is reconstructed
correctly for the sighash.
This commit fixes a potential blocking when notifying invoice updates.
When a new subscription client is created followed by an immediate
cancel, it's likely the client will be removed from the registry's
map(noop) and then added to its map again. This subscription will then
be kept in registry until lnd is restarted. Another more serious issue
is when multiple subscriptions are made for the same invoice, when the
above case happens, other subscriptions may never send invoice updates
because a previous client has a stopped notification queue that blocks
following notifications.
when payment_hash or final_cltv_delta and payment_request was set, the error message showed that the parameters shouldn't be set with dest instead of payment_request
