Allows certain sweep inputs to be kept in separate transactions at all
times. This is a preparation for anchor outputs. Before the commitment
tx confirms, there are three potential anchors that can be cpfp'ed. We
want to cpfp them all, but if done in the same transaction, the
transaction would guaranteed to be invalid. Exponential backoff would
eventually get the txes published, but having exclusive groups makes the
process faster.
After renewing the certificate, the new certificate wasn't actually
loaded and used, causing the old one to be used until lnd was restarted.
This fixes that by reloading it after it has been written.
This commit makes lnd recreate its TLS certificate if the config's
tlsextradomains or tlsextraips changed. This is useful, since earlier
user would have to manually delete the files to trigger lnd to recreate
them.
To ensure users don't accidentally have their TLS certificate recreated,
we gate it behind a flag --tlsautorefresh that defaults to false.
This commit creates a new utility method IsOutdated that can be used to
check whether a TLS certificate mathces the extra IPs and domains given
in the lnd config.
Adds an integrated routing test of probability extrapolation for untried
channels. The larger part of this commit is mock code to simulate the
Lightning Network.
The difference between this test and the existing pathfinding tests, is that
this test focuses on the feedback loop from result interpretation via
mission control updates and probability estimation back to pathfinding.
Improvements like probability extrapolation were previously only
validated by reasoning, while this setup makes it possible to assert the
improvement in a test and guard it for the future.
Updates were always restored with the same log index. This could cause a
crash when the logs were compacted and possibly other problems
elsewhere.
Extended unit test to cover the crash scenario.
This changes replaces the pending an waiting booleans in fetchChannels
with optional filters which can be more flexibly used. This change
allows filtering of channels without having to reason about the matrix
of possible boolean combinations. A test is added to ensure that the
combinations of these filters act as expected.
This commit adds LinkErrors with failure details to htlcs which fail on
our incoming link. This change is made with the intention of notifying
detailed htlc failure reasons in sendHTLCError. The FailureDetail
interface is implemented on FailureResolutionResults so that they can
directly be used to enrich LinkErrors. sendHtlcError is updated to
take a LinkError in preparation for the addition of a htlcnotifier
which will notify the detail of the error.
This commit adds a linkError field to track the value of failures
which occur at our node. This field is set when local payments or
multi hop htlcs fail in the switch or on our outgoing link. This
addition is required for the addition of a htlc notifier which will
notify these failures in handleDownstreamPacket.
The passing of link error to failAddPacket removes the need for an
additional error field, because the link error's failure detail will
contain any additional metadata. In the places where the failure detail
does not cover all the metadata that was previously supplied by addr
err, the error is logged before calling failAddPacket so that this
change does not reduce the amount of information we log.
Add a FailureDetail interface which allows us have different kinds of
failures for link errors. This interface will be used to cover failures
that occur when on invoice payment, because the errors have already
been enumerated in the invoices package.
Rename FailureDetail in a separate commit so that a FailureDetail
interface can be introduced in the following commit.
OutgoingFailureOnionDecode is renamed to OutgoingFailureDecodeError
to specifically indicate that we could not decode the wire
failure that our payment experienced.
This commit splits the resolution result enum into results divided
by outcome (settled, failed or accepted). This allows us to more
strictly control which resolution results can be used with which
HtlcResolution structs, to prevent the combination of a settle
resolution result with a failure resolution result, for example.
This commit repalces the htlcResolution struct with an interface.
This interface is implemeted by failure, settle and accept resolution
structs. Only settles and fails are exported because the existing
code that handles htlc resolutions uses a nil resolution to indicate
that a htlc was accepted. The accept resolution is used internally
to report on the resolution result of the accepted htlc, but a nil
resolution is surfaced. Further refactoring of all the functions
that call NotifyExitHopHtlc to handle a htlc accept case (rather than
having a nil check) is required.
