In this commit, we fix an existing bug in the pruneGraphNodes method.
Before this commit, if a node was involved in a channel, but only one of
the edges was advertised, then either it, or the other node would be
erroneously pruned from the graph. They shouldn't be pruned as there's
still an edge connecting the, although only 1/2 of the edge is actually
advertised.
In order to fix this, we'll now do two passes: the first pass will
populate a ref count map of all known nodes in the graph, the second
pass will increment the ref count each time a node is found in the
graph. With this two pass method, we ensure that nodes are only deleted
if there are absolutely no edges pointing to them within the graph.
In this commit, we extend the TestPruneGraphNodes test to also test the
case of when a node is involved in a channel, but only a single edge for
that channel has been advertised. In order to test this, we add an
additional node to the graph, and also a new channel. However, this
channel will only have a single edge advertised. As result, when we
prune the set of edges, the only node remaining should be the node that
didn't have any edges at all.
callbacks
The FindPeer and SendToPeer callbacks are no longer needed within the
fundingManager due to the previous commit allowing us to send messages
to peers directly.
In this commit, we modify the existing message sending functionality
within the fundingmanager. Due to each mesage send requiring to hold the
server's lock to retrieve the peer, we might run into a case where the
lock is held for a larger than usual amount of time and would therefore
block on sending the message within the fundingmanager. We remedy this
by taking a similar approach to some recent changes within the gossiper.
We now keep track of each peer within the internal fundingmanager
messages and send messages directly to them.
In this commit, we modify the way to handle historical spend dispatches
to ensure that we don't block the client for very old rescans. Rather
than blocking and waiting for the rescan to finish (which may take
minutes in the worst case), we'll now instead launch a goroutine to
handle the async response of the rescan.
Due to some of the previous commits, we no longer have persistent
connections to peers whom we have no open channels with. It might be the
case that this is triggered throughout any of the tests, so we'll ensure
that the Alice and Bob harnesses are connected before running each test.
In this commit, we extend the server's functionality to prune link nodes
on startup. Since we currently only decide whether to prune a link node
from the database based on a channel close, it's possible that we have
link nodes lingering from before this functionality was added on.
In this commit, we alter cooperative channel closures to also use
MarkChannelResolved in order to unify the logic for the different types
of channel closures.
In this commit, we update the main invoiceEvents channel within the
invoiceregistry to now have an initial buffer size of 100. We do this as
it's been reported by users that on start up they're unable to actually
create or settle invoices manually. Traces have shown that this is due
to contention while holding the invoice mutex. To attempt to solve this,
we add an additional buffer to the channel as most sends will now be
routinely non blocking.
In this commit, we fix an existing bug related to duplicate invoice
settle.s Before this commit, the second (and later) times an invoice was
settled we would return a nil pointer. This would result in the new
invoiceRegistry panicing as it would go to attempt to notify with a nil
invoice.
We fix this by returning the invoice on disk (unmodified) for each
settle after the initial one.
Fixes#1568.
In this commit, we add a new test to ensure that duplicate invoice
settles work as expected. At the present time, this test will fail as
the second to last assertion fails as we'll return a nil invoice the
second time around.
