If the provided ChainHash in a QueryChannelRange message does not match
that of our current chain, then we should send a blank response, rather
than reply with channels for the wrong chain.
This shortcut does not work when the destination is a private node. We
also don't have this shortcut for regular payments. This commit
aligns the behavior between SendPayment and QueryRoutes.
This commit updates the channel state machine to
persistently store remote updates that we have received a
signature for, but that we haven't yet included in a commit
signature of our own.
Previously those updates were only stored in memory and
dropped across restarts. This lead to the production of
an invalid signature and channel force closure. The remote
party expects us to include those updates.
This test asserts that remote updates that are locked-in on the local
commitment, but haven't been signed for on the remote commitment, are
properly restored after a restart.
The default was increased for the main sendpayment RPC in commit
d3fa9767a9729756bab9b4a1121344b265410b1a. This commit sets the
same default for QueryRoutes, routerrpc.SendPayment and
router.EstimateRouteFee.
Update the ChannelLink interface to specifically
return the LinkError struct. This error implements
the ClearTextError interface, so will be picked
up as a routing realted error by the router.
With LinkErrors implemented, the switch now
returns a LinkError for all failures on our
incoming/outgoing link and ForwardingError when
the failure occurs down the line.
Update the type check used for checking local payment
failures to check on the ClearTextError interface rather
than on the ForwardingError type. This change prepares
for splitting payment errors up into Link and Forwarding
errors.
This change introduces a LinkError implementation
of the ClearTextError interface. This error is intended
to represent failures which occur on our incoming and
outgoing link when sending, receiving and forwarding
htlcs. Paired with ForwardingError, which is represents
failures that did not occur at our node, this error
covers all non-opaque errors that the switch experiences.
This commit adds a ClearTextError interface
which is implemented by non-opaque errors that
we know the underlying wire failure message for.
This interface is implemented by ForwardingErrors,
because we can fully decrypt the onion blob to
obtain the underlying failure reason. This interface
will also be implemented by errors which originate
at our node in following commits, because we know
the failure reason when we fail the htlc.
The lnwire interface is un-embedded in the
ForwardingError struct in favour of implementing
this interface. This change is made to protect
against accidental passing of a ForwardingError
to the wire, where the embedded FailureMessage
interface will present as wire failure but
will not serialize properly.
Add a constructor for the creation of forwarding errors.
A special constructor is added for the case where we have
an unknown wire failure, and must set a nil failure message.
On both Android and iOS (when not using a simulator) the application
procees doesn't have write permissions to the default lnd directory.
This commit adds a note about using the app directory given by the used
platform.
The wallet unlocker service also requires the TLS certificates to be
added, but this was not set. This commit sets the options similar to
what is done for the regular RPC server.
Before this commit, both writing and reading an encoded empty set of
short channel IDs from the wire would fail. Prior to this commit, we
treated decoding an empty set as a caller error, and failed to write out
the zlib encoding of an empty set in a way that us and the other
implementations were able to read.
To fix this, rather than giving zlib an empty buffer to write out (which
results in an encoding with the zlib header data and the rest), we just
write a blank slice. When decoding, if we have an empty query body, then
we'll return a `nil` slice.
With the above changes, we'll now always write out an empty short
channel ID set as:
```
0001 (1 byte follows) || <encoding_type>
```
A new test has also been added to exercise this case for both known
encoding types.
Since spaces where trimmed only after checking for empty strings, an
empty flag '-- ' would be passed along to lnd. Intead we trim first to
properly ingore such flags.
Modifies TestMissingFeatureDep and TestDestPaymentAddr to use the test
ctx directly instead of generating a closure and using local state to
modify restrictions.
Previously only the fee rate used for the last sweep (the sweep bucket
average) was reported. This commit adds the request fee preference to
the report, which is used to select a bucket and the sweep tx fee rate.
