This commit adds a new primary goroutine to the server struct:
peerBootstrapper. If peer boostrapping isn’t disabled in the config,
this new goroutine will be launched to attempt to establish a set of
initial connections for a new node. The logic is pretty straight
forward: first a set of initial connections is attempted, if after our
first epoch, we don’t have enough connections yet, then we’ll attempt
to query for an additional set. In each iteration, if we haven’t been
successful, then we increase our exponential backoff in order to not
spam any of our bootstrapping sources.
This commit adds a new interface the to discovery package:
NetworkPeerBootstrapper. The NetworkPeerBootstrapper interface is meant
to be used to bootstrap a new peer joining the network to the set of
existing active peers within the network. Callers are encouraged to
utilize several boostrappers in series as redundant sources of
information. The MultiSourceBootstrap function will takes a set of
boostrappers, and compose their outputs into a single unified set of
addresses.
Two concrete implementations of the NetworkPeerBootstrapper interface
have been added as a part of this commit: the ChannelGraphBootstrapper
and the DNSSeedBootstrapper. The former will utilize the authenticated
node advertisements within the calling nodes view to boostrap new
connections. The latter will use a set of BOLT-0010 compliant DNS seeds
to query. This DNS seeding more will likely be used by nodes initial
joining the network, as they may not yet have the channel graph as they
haven’t connected to any peers.
This commit fixes an existing bug in the announcement processing of the
authenticated gossiper. We will now only examine an incoming
announcement for validity if it targets the chain that we’re currently
active on.
In this commit we’ve updated to the latest versions of roasbeef/btcutil
and ltcsuite/ltcd. With this change we fix two bugs:
* The Bech32HRPSegwit parameter wasn’t being copied over in
applytLiteCoinParams
* btcutil.DecodeAddress wasn’t properly using the passed net params
We no longer attach the RPC client to the lnwallet logging instance as
it can generate a ton of spam in trace mode as it’ll dump the entire
hex encoded blocks, transactions, etc.
Previously, our old lnwire.Error message used a special code to
indicate different types of errors. With the recent push for spec
compatibility, we removed this field and instead stuffed the error into
the first byte of the error data. This works between lnd nodes, but
with other implementations they may send different errors which use a
different error scheme.
To fix this, we’ll now unconditionally return the error to the end
caller (if one exists).
This commit fixes a prior goroutine leak that could result in a node
having thousands of goroutines, particularly due to many concurrent
channel fundings. We now ensure that for each BlockEpoch client
created, we ensure that the client is cancelled once the creating
grouting exits.
This modifies the tests that deal serializing the Invoice type to limit
the creation date to seconds since Go1.9 added the concept of a
monotonic component to times which does not round trip through
MarshalBinary and UnmarshalBinary and therefore causes the tests to fail.
In particular, it modifies the creation dates in the randInvoice,
makeFakePayment, makeRandomFakePayment, and TestInvoiceWorkflow
functions.
This results in allowing TestOutgoingPaymentSerialization,
TestOutgoingPaymentWorkflow, and TestInvoiceWorkflow to pass.
This corrects the fuzz test in TestLightningWireProtocol for
MsgCommitSig to avoid creating an empty slice since the decoded message
only creates a slice when there are greater than zero signatures and an
empty slice is not considered equal to a nil slice under reflection.
This can be tested by running the TestLightningWireProtocol 1000 times
in a loop with and without this change.
This commit adds a precautionary check for the error returned if the
channel hasn’t yet been announced when attempting to read the our
current routing policy to initialize the channelLink for a channel.
Previously, if the channel wasn’t they announced, the function would
return early instead of using the default policy.
We also include another bug fix, that avoids a possible nil pointer
panic in the case that the ChannelEdgeInfo reread form the graph is
nil.
This commit fixes a bug within the HTLC construction and commitment
transaction construction that would result in HTLC _values_ within the
commitment transaction being off by a factor of 1000. This was due to
the fact that we failed to convert the amount of an HTLC, in mSAT, to
SAT before placing it as an output within the commitment transaction.
When attempt to locate the output index of a particular half, we use
the unconverted amount, meaning it was unnoticed.
This commit adds a new assertion within the TestSimpleAddSettleWorkflow
test to ensure that the HTLC is found within the commitment transaction
with the proper value in satoshi.
This commit updates the glide hashes for btcd, neutrino, and btcwallet
to their latest versions. This change was prompted, as we've recently
fixed two bugs: one in btcd, and one in neutrino. The btcd in btcd was
due to not properly setting a pointer, which caused the new gcs related
RPC calls to now respond correctly. The neutrino bug was due to a nil
pointer panic that was triggered by not ensuring that we actually had a
`syncPeer` before referencing it.
This commit introduces a RetributionStore interface, which
establishes the methods used to access persisted information
regarding breached channels. A RetributionStore is used to
persist retributionInfo regarding all channels for which
the wallet has signaled a breach.
The current design could be improved by moving certain
functionality, e.g. closing channels and htlc links, such
that they are handled by upstream by their respective
subsystems. This was investigated, but deemed preferable to
postpone to a later update to prevent the current
implementation from sprawling amongst too many packages.
The test suite creates a mockRetributionStore and ensures that
it exhibits the same behavior as the retribution store backed
by a channeldb.DB.
This commit adds a breached contract retribution storage layer using
boltdb to the breach arbiter. The breach arbiter now stores retribution
state on disk between detecting a contract breach, broadcasting a
justice transaction that sweeps the channel, and finally witnessing the
justice transaction confirm on the blockchain. It is critical that such
state is persisted on disk, so that if our node restarts at any point
during the retribution procedure, we can recover and continue from the
persisted state.
This commit updates the glide packages in the repo to point to the
latest btcsuite repos. With this change, we’ll now be able to take
advantage of many of the recent updates to the btcsuite package of
repos. One highlight is that after this commit, we’ll now be using
bech32 by default for p2wkh addresses.
This commit updates the installation docs to specify the min golfing
version. Additionally, we ensure that users running on linux will
download the latest version of golfing from their ppa. Finally, we also
now link directly to the golfing page of pre-compiled binaries for
users that seek to grab the source directly from the official goading
website.
Fixes#263.
This commit fixes a bug that could arise if either we had not, or the
remote party had not advertised a routing policy for either outgoing
channel edge. In this commit, we now detect if a policy wasn’t
advertised, falling back to the default routing policy if so.
Fixes#259.
This commit is a precautionary commit put in place in order to ensure
that the logic of macaroon retrieval doesn’t run into a bug triggered
by returning a reference into bolt’s active memory map. This can arise
if one returns a pointer directly read from the database. We seek to
avoid this by instead ensuring all byte slices are fully copied before
returning.
