In this commit, we modify the deDupedAnnouncements struct slightly. The
element of this struct will now keep track of the set of senders that
sent a particular message. Each time a message is added, we’ll replace
the new message with the old (as normal), but we’ll also add the new
sender to the set of known senders.
With this new feature, we’ll be able to avoid re-sending a message to
the peer that sent it to us in the first place.
In this commit, we add additional detail in the error return hen were’e
unable to properly decode an encapsulated error. This additional
logging was added with the goal of being able to track down a lingering
bug, where at times lnd cannot decode a TemporaryChannelFailure
message.
This commit fixes a lingering bug that could at times cause
incompatibilities with other implementations when attempting a
cooperative channel close. Before this commit, we would use a pointer
to the funding txin everywhere. As a result, each time we made a new
state, or verified one, we would modify the sequence field of the main
txin of the commitment transaction. Due to this if we updated the
channel, then went to do a cooperative channel closure, the sequence of
the txin would still be set to the value we used as the state hint.
To remedy this, we now copy the txin each time when making the
commitment transaction, and also the cooperative closure transaction.
This avoids accidentally mutating the txin itself.
Fixes#502.
This commit fixes a deadlock that could occur when
a peer disconnected during a call to sentToPeer. In
This particular case, a message would successfully
be queued, the peer would shutdown, and we would
block waiting for an error to be returned on the
message's error channel, which would deadlock.
This fixes that by also checking for peer shutdown.
In this commit, we modify the CloseChannel to wait for both nodes to
detect that channel as being active before we attempt to close it. This
should serve to reduce many of the flakes that we’ve been seeing on
travis which were caused by node A detecting the channel as active, but
node B not, leading to a test flake under certain timing conditions.
The new function uses the recently added WaitPredicate method.
Recent changes to the funding manger’s state machine have resulted in
some additional database calls during the funding process. This has
slowed down the tests by a few ms here and there. Recent integration
test runs have begun to fail due to AssertChannelExists returning an
error as the channel hasn’t fully propagated yet. In order to remedy
this, we’ll now use WaitPredicate to poll repeatedly to ensure. This
should serve to reduce flakes encountered within the integration tests.
In this commit, we add a new helper function to the NetworkHarness
struct. This helper function serves to allow test authors to look up
pointer to an active node based on its current public key.
Each time a new node is started, its public key will be re-registered
within the global nodesByPub map.
This commit makes the gossiper track the state of a local
AnnounceSignature message, such that it can retry sending
it to the remote peer if needed. It will also persist this
state in the WaitingProofStore, such that it can resume
from this state at startup.
This commit adds a test that ensures that if we receive a
ChannelUpdate for a channel we don't know about, it will
be reprocessed after we receive a ChannelAnnouncement for
that channel.
This commit makes the gossiper store received ChannelUpdates
that is not for any known channel in a map, such that they
can be reprocessed when the ChannelAnnouncement arrives.
This is done to handle the case where we receive a ChannelUpdate
from our channel counterparty before we have been able to process
our own local ChannelAnnouncement.
This commits slightly rewrites the newly introduced
logic for private channels. Instead of keeping the
channel announce preference in a database within
fundingManager, it is stored as part of the
OpenChannel struct.
In addition, the ChanOpenStatus_Open update is now
sent after the channel is added to the router, instead
of waiting until the 6 blocks confirmation has passed.
This commit adds some comments and does some cleanup
of the logic that makes sure non-public channels
(channels with no AuthProof) are not broadcasted
to the network.
This commit adds the ChannelFlags field, of type
lnwire.FundingFlags, to the OpenChannel struct,
including serialization for database storage.
This is done to preserve the flags that were
sent during channel opening, currently used
to determine whether a channel should be made
public or not after opening.
This commit introduces some new interdependent functionality. As
soon as the fundingLocked message is sent, the channel is
immediately added to the ChannelRouter's internal topology.
Finally, channels are now only broadcasted to the greater
network after six confirmations on the funding transaction
has been reached.
On testate as times the fee estimation can swing widely. As we
currently don’t yet use vsize everywhere internally, we’re forced to
manually scale to weight for the moment. If the returned fee rate is
too low, then it can cause our estimate to go to zero. This also has
the effect of meaning that the chanCloser doesn’t currently advance if
the initial starting fee is zero.
