In this commit, we add a new proto generation script to match the one in
the main lnrpc package. This script differs, as we don't need to
generate the REST proxy stuff (for now).
In this commit, we introduce a new sub-package within the greater RPC
package. This new sub-package will house a new set of sub-RPC servers
to expose experimental features behind build flags for upstream
consumers. In this commit, we add the first config for the service,
which will simply expose the lnwallet.Signer interface over RPC.
In the default file, we have what the config will be if the build tag
(signerrpc) is off. In this case, the config parser won't detect any
times, and if specified will error out. In the active file, we have the
true config that the server will use. With this new set up, we'll
exploit these build flags heavily in order to create a generalized
framework for adding additional sub RPC servers.
In this commit, we update the makefile to be aware of go modules. Along
the way, we remove all references to dep as we no longer use it within
this project. Note that in order to allow usage of go modules within the
$GOPATH directory, we set the `GO111MODULE=on` environment variable.
In this commit, we modify all existing historical rescans for
ChainNotifier backends to scan backwards rather than forwards. If we
know that a transaction has been confirmed, or outpoint spent, the it's
likely that the event has recently transpired assuming we've been
offline for a short period of time. Therefore, if we scan backwards
rather than forwards, then we can save potentially hundreds or thousands
of block fetches if the event recently happened close to the tip of the
chain.
We bound this search at the genesis block, to ensure we don't underflow
the uint32 used throughout the package in the main loop.
This adds the scenario where a channel is closed while the node is
offline, the node loses state and comes back online. In this case the
node should attempt to resync the channel, and the peer should resend a
channel sync message for the closed channel, such that the node can
retrieve its funds.
We pool the database for the channel commit point with an exponential
backoff. This is meant to handle the case where we are in process of
handling a channel sync, and the case where we detect a channel close
and must wait for the peer to come online to start channel sync before
we can proceed.
This commit adds an optional field LastChanSyncMsg to the
CloseChannelSummary, which will be used to save the ChannelReestablish
message for the channel at the point of channel close.
This commit adds a new file legacy_serialization.go, where a copy of the
current deserializeCloseChannelSummary is made, called
deserializeCloseChannelSummaryV6.
The rationale is to keep old deserialization code around to be used
during migration, as it is hard maintaining compatibility with the old
format while changing the code in use.
