In this commit, we fix the logging when adding new gossip syncers. The
old log would log the byte array, rather than the byte slice. We fix
this by slicing before logging.
This commit adds a poll 20 ms interval to WaitPredicate, similar to what
is done for WaitInvariant. This makes the predicate not being checked
super-rapidly, potentially filling the logs with useless info over the
wait predicate interval.
In this commit, we finish the fix for the inbound/outbound peer bool in
the server. The prior commit forgot to also flip the inbound/output maps
in Inbound/Outbound peer connected. As a result, the checks were
incorrect and could cause lnd to refuse to accept any more inbound
connections in the case of a concurrent connection attempt.
With the recent bug fixes in the peer connection, it's no longer the
case that just disconnecting a certain peer causes it to no longer
connect to the other. As a result, we now shutdown Alice to ensure no
reconnection occurs. We'll then later restart alice when we restart
dave.
In this commit, we ensure that if we're already ignoring a connection,
then we also ignore the pending persistent connection request.
Otherwise, we'll move to accept the replaced connection, but then
continue to attempt connection requests.
In this commit, we modify the look up for inbound peers to ensure that
we connect to the "freshest" address until we need to execute the
peerTerminationWatcher. We do this as it's possible for a channel to be
created by the remote peer during our session. If we don't query for the
node's address at the latest point, then we'll miss this new node
announcement for the node.
This commit adds the helper method shutdownAndAssert, and makes us shut
down nodes created temporarily during the test cases using defers
instead of at the end of the test. This makes it easier to remember to
shut them down, as it is done right after they are started.
This commit changes the gossiper to direct messages to
peer objects, instead of sending them through the
server every time. The primary motivation is to reduce
contention on the server's mutex and, more importantly,
avoid deadlocks in the Triangle of Death.
In this commit, we ensure that the packet queue will always exit, by
continually signalling the main goroutine until it atomically sets a
bool that indicates its has been fully shutdown. It has been observed
that at times the main goroutine will wake up (due to the signal), but
then bypass the select and actually miss the quit signal, as a result
another signal is required. We'll continue to signals in a lazy loop
until the goroutine has fully exited.
This commit moves the generic interface for
Lightning Network peers so that it can be
imported directly into the switch and gossiper.
Eventually, the majority of the peer logic
would be moved into this package for testing
and modularization.
In this commit we modify the existing sendtoroutes command such that
users can either specify the route over stdin (using the special '-'
flag), via the keyword argument, or via the positional argument.
In this commit, we modify the logic for the two primary payment related
RPCs to reduce duplication, indentation, and consolidate logic. As a
result, we'll now accept rpcPaymentIntents, turn those into regular
paymentIntents (convert from proto) before finally dispatching via
unified function.
In this commit, we modify the recent refactoring of the mission control
sub-system to overload the existing payment session, rather than create
a brand new one. This allows us to re-use more of the existing logic, and
also feedback into mission control the failures incurred by any user
selected routes.
This commit add 3 integration tests for send-to-route RPC call.
One test ensures that single-hop payments are processed. Another test
checks that payments through a multi-hop route are processed. Lastly,
there is a test to check error propagation while sending payments via fake
predefined route.
This commit removes a possible deadlock in the switch,
which can be triggered under certain failure conditions.
Previously, we would acquire the link's read lock for
the duration of HtlcSatisfiesPolicy, though we only
need to use it grab the current policy. The deadlock could
be caused in the cases where we attempt to log the failure,
which access the read-protected ShortChanID method.
In this commit, we address the meaning of the inbound parameter to
peerConnected. An inbound connection is defined as a connection
initiated by the peer, rather than ourselves.
We also update the inbound value for the peerConnected calls within
OutboundPeerConnected and InboundPeerConnected to reflect the definition
above.
We remove the internale broadcastMessage method, and instead handle the
mutex handling within BroadcastMessage. This lets us hold the mutex only
when neccessary.
This commit removes the sendToPeer method from the server, and instead
moves the necessary logic into SendToPeer. This let's us make the mutex
acquisition more fine-grained, only holding it while reading from the
peer map. Earlier it was required to be held during the whole call to
sendToPeer, as the method would access the map internally.
