This commit implements an easy optimization by using bolt db’s Batch
method when writing payment details to disk. The AddPaymnent method can
be concurrently called by thousands of grouting due to the way the
payment dispatch pipeline is architected. With this commit, we shave of
a significant amount of running time when users are sending thousands
of payments a second as what would’ve been thousands of writes can now
be coalesced into one or two writes!
This commit eliminates a possible deadlock (or repeated peer connection
failures) that can arise due to the [inbound|outbound]PeerConnected
methods holding the peer mutex too long. We now alleviate this
concurrency issue by calling s.peerConnected in an asynchronous manner.
This is safe as all operations within the method are themselves
goroutine-safe.
This commit fixes a build issue that appears when attempting to
cross-compile binaries to a 32-bit system from a 64-bit system. The
issue was that the defined max-state hint overflows a 32-bit integer. To
fix this issue, we now proeprly specify a type of a uint64 for the typed
constant.
Error `connection refused` was thrown when user tries to get "Alice" to
connect to "Bob" node due to port mismatch introduced in this change [1]
here.
This commit updates the port value to reflect the new change introduced in
[1].

This commit fixes a race condition that was introduced while fixing a
lingering bug in the logic to notify block epoch clients. The race
condition would happen as by removing the default case in the select
statement, it was now possible for the client’s block epoch client to
be closed while the routine was attempting a send on it.
We now eliminate this race condition possibility by adding a wait group
to all goroutines launched to dispatch a block epoch notification. With
this modification, the Stop() goroutine will now wait for all other
goroutine to exit before closing the block epoch channels of all
currently registered clients.
This commit removes all the prior temporary feature bits which were
only added in order to allow clients to gracefully continue functioning
in the midst of all the breaking changes that were landing in the
master branch of the project.
A common pitfall with new users setting up lnd on test net has been
observed to be the initial RPC credential set up between btcd and lnd.
As of a recent version of btcd now performs automatic RPC credential
set up by generating a random rpcuser and rpcpass on start up.
We now take advantage of this by reading the RPC credentials (if
possible and running in simmer mode). As a result, it is now possible
to simply run: `lnd—testnet` assuming a fresh installation of bcd (with
a set btcd.conf).
Fixes#68.
This commit bolsters the logging available within the lnwallet package
by include the logging from both web sockets connections, and the
wtxmgr as part of the exposed package level logging. With this, users
will gain additional avenues for obtaining debug logs from various
parts of the system.
This commit implements some minor coding style, commenting and naming
clean up after the recent major discovery service was merged into the
codebase.
Highlights of the naming changes:
* fundingManager.SendToDiscovery -> SendAnnouncement
* discovery.Discovery -> discovery.AuthenticatedGossiper
The rest of the changes consist primary of grammar fixes and proper
column wrapping.
This commit a bug introduced in the chain notifier while we were
limiting the usage of mutexes within the package. In a prior commit a
default case was introduced in the select statement in order to avoid
the possibility of the main goroutine blocking when dispatching block
epoch notification.
In order to avoid this potentially disastrous bug, we now instead
launch a new goroutine for each client to ensure that all notifications
are reliably dispatched.
This commit slightly modifies the handling of the Connect RPC to allow
users to omit the port when specifying the target node to connect to.
If the port isn’t specified, then the default p2p port will be used in
place.
Added the signer which will be needed in the funding manager to sign
the lnwaire announcement message before sending them to discovery
package. Also in the future the message signer will be used to sign
the users data.
Originally we adding the edge without proof in order to able to use it
for payments path constrcution. This method will allow us to populate
the announcement proof after the exchange of the half proofs and
constrcutrion of full proof finished.
In case if the channel shouldn't be announced to the rest of the network
the proof, which is needed to announce the channel, will not be
populated, fot that reason the ability to store the empty proof has
been added.
Change the name of fields of messages which are belong to the discovery
subsystem in a such way so they were the same with the names that are
defined in the specification.
In this commit announcement signature message has been added which is
needed when peers want to announce their channel to the rest of the
network. This message acts as half proof carrier, nodes exchanges
their half proofs with each other and after that they are able to
construct the full proof.
Add usage of the 'discovery' package in the lnd, now discovery service
will be handle all lnwire announcement messages and send them to the
remote party.
In this commit the routing package was divided on two separete one,
this was done because 'routing' package start take too much responsibily
on themself, so with following commit:
Routing pacakge:
Enitites:
* channeldb.ChannelEdge
* channeldb.ChannelPolicy
* channeldb.NodeLightning
Responsibilities:
* send topology notification
* find payment paths
* send payment
* apply topology changes to the graph
* prune graph
* validate that funding point exist and corresponds to given one
* to be the source of topology data
Discovery package:
Entities:
* lnwire.AnnounceSignature
* lnwire.ChannelAnnouncement
* lnwire.NodeAnnouncement
* lnwire.ChannelUpdateAnnouncement
Responsibilities:
* validate announcement signatures
* sync topology with newly connected peers
* handle the premature annoucement
* redirect topology changes to the router susbsystem
* broadcast announcement to the rest of the network
* exchange channel announcement proofs
Before that moment all that was in the 'routing' which is quite big for
one subsystem.

This commit modifies the logic around the opening p2p handshake to
enforce a strict timeout around the receipt of the responding init
message. Before this commit, it was possible for the daemon and certain
RPC calls to deadlock as if a peer connected, but didn’t respond with
an init msg, then we’d be sitting there waiting for them to respond.
With this commit, we’ll now time out, kill the connection and then
possible attempt to re-connect if the connection was persistent.
Use addresses and ports from NodeAnnouncement messages for reconnection
attempts. For those nodes that don't explicitly report IP addresses, use
the IP address from previous connections connection request along with
the default peer port number.
Minor change to server.go to add ExternalIPs to
channeldb.LightningNode. Also, added a test that utilizes this
functionality and exercises multiple addresses in NodeAnnouncement.
This commit modifies address handling in the NodeAnnouncement struct,
switching from net.TCPAddr to []net.Addr. This enables more flexible
address handling with multiple types and multiple addresses for each
node. This commit addresses the first part of issue #131 .
