This modifies the various channelnotifier notification functions
to instead hit the server and then call the notification routine.
This allows us to accurately modify the server's maps.
Here we introduce the access manager which has caches that will
determine the access control status of our peers. Peers that have
had their funding transaction confirm with us are protected. Peers
that only have pending-open channels with us are temporary access
and can have their access revoked. The rest of the peers are granted
restricted access.
In this commit, we add a `GraphSession` method to the `ChannelGraph`.
This method provides a caller with access to a `NodeTraverser`. This is
used by pathfinding to create a graph "session" overwhich to perform a
set of queries for a pathfinding attempt. With this refactor, we hide
details such as DB transaction creation and transaction commits from the
caller. So with this, pathfinding does not need to remember to "close
the graph session". With this commit, the `graphsession` package may be
completely removed.
The `graphsession.NewRoutingGraph` method was used to create a
RoutingGraph instance with no consistent read transaction across calls.
But now that the ChannelGraph directly implements this, we can remove
The NewRoutingGraph method.
In this commit, we add the --no-backup-archive with a default
as false. When set to true then previous channel backup file will
not be archived but replaced. We also modify TestUpdateAndSwap
test to make sure the new behaviour works as expected.
We add a new config option to set the `ProofMatureDelta` so the users
can tune their graphs based on their own preference over the num of
confs found in the announcement signatures.
In this commit we start to break up the starting process into smaller
pieces, which is needed in the following commit to initialize blockbeat
consumers.
Find and replace all nolint instances refering to the `lll` linter and
replace with `ll` which is the name of our custom version of the `lll`
linter which can be used to ignore log lines during linting.
The next commit will do the configuration of the custom linter and
disable the default one.
and the same for ChannelStateDB.FetchChannel. Most of the calls to these
methods provide a `nil` Tx anyways. The only place that currently
provides a non-nil tx is in the `localchans.Manager`. It takes the
transaction provided to the `ForAllOutgoingChannels` callback and passes
it to it's `updateEdge` method. Note, however, that the
`ForAllOutgoingChannels` call is a call to the graph db and the call to
`updateEdge` is a call to the `ChannelStateDB`. There is no reason that
these two calls need to happen under the same transaction as they are
reading from two completely disjoint databases. And so in the effort to
completely split untangle the relationship between the two databases, we
now dont use the same transaction for these two calls.
Our aim is to completely remove the `channeldb.DB`'s direct dependence
on the `graphdb.ChannelGraph` pointer. The only place where it still
depends on this pointer is in the `(DB).AddrsForNode(..)` method where
it queries both the channel DB and the graph db for the known addresses
for the node in question and then combines the results. So, to separate
these out, we will define an AddrsForNodes interface in this commit
which we will later let both the ChannelGraph and channeldb.DB both
implement and we will merge these results outside of the channeldb
package.
All this commit does is to unify the `AddrSource` interface since this
has been defined separately in a couple of places.
All the structs defined in the `channeldb/models` package are graph
related. So once we move all the graph CRUD code to the graph package,
it makes sense to have the schema structs there too. So this just moves
the `models` package over to `graph/db/models`.
This commit fixes a case where the peer blocks the shutdown process.
During the shutdown, the server will call `s.DisconnectPeer`, which
calls `peer.Disconnect`. Because the peer never enters `peer.Start` via
`s.peerInitializer`, the `startReady` chan will not be closed, causing
`peer.Disconnect` to hang forever. We now fix it by only block on
`startReady` when the peer is started.
If a node contains a channel, but doesn't have a corresponding edge in
the graph database, updating the channel policy would fail. In this
commit the edge is recreated if the channel exists. This ensures a node
can recover from a missing edge in the graph database by calling
updatechanpolicy.
Similar to the sweeper, when we're about to make a new breach
transaction, we ask the sweeper for a new change address, if it has one.
Then when we go to publish, we notify broadcast.
In this commit, we start to use the AuxSweeper (if present) to obtain a
new extra change addr we should add to the sweeping transaction. With
this, we'll take the set of inputs and our change addr, and then maybe
gain a new change addr to add to the sweep transaction.
The extra change addr will be treated as an extra required tx out,
shared across all the relevant inputs. This'll also be used in
NeedWalletInput to make sure that we add an extra input if needed to be
able to pay for the change addr.
In this commit, we add a new AuxSweeper interface. This'll take a set of
inputs, and a change addr for the sweep transaction, then optionally
return a new sweep output to be added to the sweep transaction.
We also add a new NotifyBroadcast method. This'll be used to notify
that we're _about_ to broadcast a sweeping transaction. The set of
inputs is passed in, which allows the caller to prepare for the ultimate
broadcast of the sweeping transaction.
We also add ExtraTxOut to BumpRequest pass fees to NotifyBroadcast. This
allows the callee to know the total fee of the sweeping transaction.
This will be used by external callers to modify the way we resolve
contracts on chain. For a given contract, we'll store an extra "blob",
that will later be presented during the sweeping phase.
This commit renames the previous MissionControl to MissionController and
the previous MissionController interface to MissionControlQuerier. This
is done because soon the (new) MissionController will back multiple
namespaced MissionControl instances. For now, it just houses a single
MissionControl in the default namespace.
This commit also replaces the MissionControl's `now` function with a
`clock.Clock`.
