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.
This commit removes the unknown required feature bit check from the
invoice decoding logic. This allows greater utility to users of the
decodepayreq rpc since it can provide inspection of otherwise invalid
invoices. In the prior commit, this check moved into our path finding
logic, so invalid features taken from an invoice will instead cause a
failure when attempting to pay.
This commit brings us inline with recent modifications to the spec, that
say we shouldn't pay nodes whose feature vectors signal unknown required
features, and also that we shouldn't route through nodes signaling
unknown required features.
Currently we assert that invoices don't have such features during
decoding, but now that users can specify feature vectors via the rpc
interface, it makes sense to perform this check deeper in call stack.
This will also allow us to remove the check from decoding entirely,
making decodepayreq more useful for debugging.
This commit removes channeldb.FetchAllInvoices and changes tests such
that expectation sets are prepared in the test case instead of selected
from the DB.
In this commit, we update the routing package to use the new
`sphinx.NewOnionPacket` method. The new version of this method allows us
to specify _how_ the packet should be filled before it's used to create
a mix-header. This isn't a fundamental change (totally backwards
compatible), instead it plugs a privacy leak that may have revealed to
the destination how long the true route was.
This commit adds an initial peer online event for channels
that have peers that are online when they are created. This
addresses a race between the peer coming online and an
existing channel being added to the event store; if the
peer comes online first, the existing channel will not have
its initial online event added.
