In this commit, we take an initial step towards converting the existing
breach arbiter and utxo nursery logic into contract resolvers by moving
the files as is, into the `contractcourt` pacakge.
This commit is primarily move only, though we had to massage some
interfaces and config names along the way to make things compile and the
tests run properly.
Fixes#5796.
Some historical channels might not have the forwarding packages
recorded. And since the error might be silenced, the historical channel
might be nil.
With the middleware handler in place, we now need to add a new gRPC
interceptor to the interceptor chain that will send messages to the
registered middlewares for each event that could be of interest to them.
The RPC DeletePayment allows deleteing single payment from its ID. When calling with `FailedHtlcsOnly` set in the request only failed HTLCs of this payment will be deleted.
We'll want to re-use the abandon channel functionality for the batch
funding, as a cleanup in case the funding is aborted before publishing
any transaction.
This field will be examined later down the stack along with the set of
feature bits to determine if explicit channel commitment type
negotiation is possible or not.
Adds an optional tx parameter to ForAllOutgoingChannels and FetchChannel
so that data can be queried within the context of an existing database
transaction.
As a preparation to not have a local and remote version of the database
around anymore, we rename the variables into what their actual function
is. In case of the RPC server we even directly use the channel graph
instead of the DB instance. This should allow us to extract the channel
graph into its own, separate database (perhaps with better access
characteristics) in the future.
If the wallet recovery chain rescan was aborted before it finished, the
user would need to remember to use a positive recovery_window value the
next time they unlock the wallet for the rescan to continue. Because
forgetting to do so could lead to an incomplete wallet state (and
therefore potential missing funds) we rather don't allow shutting down
lnd through the RPC while a rescan is in progress.
This won't prevent any user from manually signaling Ctrl+C to kill lnd.
But that user might also check the log and see there's still something
going on that's preventing lnd from shutting down.
An often requested feature is to use the abandonchannel API in regular
builds and not only dev builds to get rid of stuck channels that had
their funding transaction invalidated.
The initial reason for putting the call behind the build flag was a
safety concern to make sure nobody uses this on active channels by
accident.
Fixes#5325.
Corrects a problem introduced in #5281 that caused the synced_to_chain
flag in the GetInfo call to never become true when the router subsystem
is running in Neutrino mode (channel validation turned off).
With this patch, we'll fail out earlier in the cycle in case of
some wonky parameters, and not leave zombie payments in the router
which currently are not cleaned up.
GetNodeInfo retrieves the policies for every edge the node belongs to.
When these policies are retrieved from the database, they're returned
in the following order: the first policy is the outgoing policy from the
node, and the second is the incoming policy to the node. This ordering
is not consistent with the ordering we have within our other RPCs like
GetChanInfo and DescribeGraph, where policies are sorted based on the
smaller public key of the nodes within an edge.
We fix this by maintaining the same order as our other RPCs.
The router has a lot of work to do for each block. So it might be
possible that it isn't yet up to date with the most recent block,
even if the wallet is. This can happen in environments with high CPU
load (such as parallel itests). Since the `synced_to_chain` flag in
the response of this call is used by many wallets (and also our
itests) to make sure everything's up to date, we add the router's
state to it. So the flag will only toggle to true once the router was
also able to catch up.
Since we want to support AMP payment using a different unique payment
identifier (AMP payments don't go to one specific hash), we change the
nomenclature to be Identifier instead of PaymentHash.
In this commit, we add strict zombie pruning as a config level param.
This allow us to add the option for those that want a tighter graph, and
not change the default composition of the channel graph for most users
over night.
In addition, we expand the test case slightly by testing that the self
node won't be pruned, but also that if there's a node with only a single
known stale edge, then both variants will prune that edge.
