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.
This commit ensures that we *always* populate the ChainHash field when
we’re crafting new channel update messages either due to the periodic
broadcast, or when we’re updating the routing policies of a set of
target channels. Previously, this wasn’t set which would cause nodes to
reject the newly crafted ChannelUpdate messages.
This commit modifies the HTLC integration tests to be mindful of the
max payment size. Rather than sending the payment in one large batch,
we instead now send it in chunks of the max payment size.
This commit modifies the relevant RPC’s to enforce the max payment size
as defined in BOLT-0002. With this commit the largest payment possible
is now 2^32 mSAT, or 4,294,967 satoshis.
This commit adds a new reqQuit channel within SendPayment. The inner
goroutine will use this channel to detect if the request itself has
exited or not. Without this method, we’d possible leak a goroutine if a
client never closed the payment stream.
This commit modifies NewWitnessAddress to return nested p2wkh address.
We do this as this RPC call was put in place to be used within GUI’s to
allow users to deposit funds into their LN wallet. By using nested
p2wkh, we ensure that the generate address that can be used to directly
create channels.
This commit adds to new RPC’s to the Lightning service: UpdateFees and
FeeReport. Additionally, we also update to the latest version of protc,
golang protobuf, and the gRPC gateway.
This commit modifies the way that we create the macaroon database, and
also create the initial macaroons themselves. Rather than creating a
new macaroon DB for each chain, we instead create a single instance for
all chains. Additionally, if the datadir has been modified, and the
macaroon paths haven’t been modified, the macaroons are now scoped to
those paths.
This commit fixes a lingering bug within the logic for the
peer/htlcswitch/channellink. When the link needs to fetch the latest
update to send to a sending party due to a violation of the set routing
policy, previously it would modify the timestamp on the message read
from disk. This was incorrect as it would invalidate the signature
within the message itself. We fix this by instead
This commit adds another conditional send select statement to ensure
that when sending the finalized contract to the breach arbiter, the
peer doesn’t possible cause the daemon to hang on shutdown.
This commit modifies the logic when we are loading alll the channels
that we have with a particular peer to grab the current committed
forwarding policy from disk rather then using the default forwarding
policy. We do this as it’s now possible for active channels to have
distinct forwarding policies.
This commit adds a new method to the HtlcSwitch:
UpdateForwardingPolicies. With this method callers are now able to
modify the forwarding policies of all, or some currently active links.
We also make a slight modification to the way that forwarding policy
updates are handled within the links themselves to ensure that we don’t
override with a zero value for any of the fields.
This commit fixes an lingering bug within the path finding logic of the
router. Previously we used the edge policy directly attached to the
outgoing channel of the node we were traversing to calculate the fees
and time lock information. This is incorrect, as we instead should be
using the policy of the *connecting* node as we’ll need to pay for
transit as they dictate.
To remedy this, we now grab the incoming+outgoing edges and use those
accordingly when building the initial path.
This commit adds a new method to the AuthenticatedGossiper:
PropagateFeeUpdate. This new method will allow callers to update the
fee schedule advertised for a particular channel, or all currently
active channels. With this method exposed, the AuthenticatedGossiper
will now craft the new channel update messages, sign the new state,
commit the new policy to the underlying graph, and finally add the
message to the next announcement epoch batch.
This commit updates the tail end of the funding workflow to properly
include the ChainHash field when crafting ChannelAnnouncements and the
initial ChannelUpdate messages. Additionally, we now properly generate
the proper signatures to match the changes to BOLT0007.
This commit modifies the generation and parsing of errors to abandon
usage of the Code field, and instead use the first byte of the Data
field to store the error codes that we currently use. With this change,
we ensure that our error messages properly match BOLT-0002.
