In this commit, we now properly examine the Flag field within the
ChannelUpdate message as a bitfield. Before this commit we would
manually check the flags for zero or one. This was incorrect as a their
bit has now been defined. To properly dispatch the messages, we’ll now
treat it properly as a bitmask.
Add option to set trickleDelay for AuthenticatedGossiper in
command line, with default value of 300 milliseconds. Pass this
value to newServer, which uses it when creating a new instance of
AuthenticatedGossiper. Also set this value to 300 milliseconds when
creating nodes in integration tests.
For Part 1 of Issue #275. Create isolated private struct in
networkHandler goroutine that will de-duplicate
announcements added to the batch. The struct contains maps
for each of channel announcements, channel updates, and
node announcements to keep track of unique announcements.
The struct has a Reset method to reset stored announcements, an
AddMsg(lnwire.Message) method to add a new message to the current
batch, and a Batch method to return the set of de-duplicated
announcements.
Also fix a few minor typos.
In this commit, we fix an existing bug that could result in a panic if
we received a ChannelUpdate message with an unknown set of flags. If
the flag wasn’t set to zero or one, then the pubKey parameter would be
still nil when we attempted to validate it, causing an error to occur.
We remedy this by instead returning an error if the flags are unknown.
In a future commit, we will properly handle the set of flags that
indicates the channel should be disabled.
This commit refactors the SynchronizeNode logic such that
it can be called without interacting with the gossiper's
main execution loop. This method does not require access
to any of the gossiper's internal state, making the change
fairly straightforward. The primary motivation behind
this change is to minimize the possibility of introducing
deadlock scenarios between the gossiper and server.
This commit fixes a slight bug in the announcement processing logic
within the AuthenticatedGossiper. Before this commit, it was possible
for us to ignore one of our now announcements due to it being
pre-mature, rendering (atm) the channel unusable by the ChannelRouter
itself. To fix this, we know only check for a pre mature announcement
iff the message is coming from a remote node.
This commit adds an additional return value to the updateChannel
method. We also now return the original ChannelAnnouncement, this can
be useful as it let’s the caller ensure that the channel announcement
will be broadcast along side the new channel update.
This commit does two things. First we fix a deadlock bug within boltdb
that could arise when the channel router attempted to open a
transaction, while the retransmission loop was attempting to send a
message to the channel router (circular wait). Second, we’ve refactored
out the retransmission into its own function. This allows us to kick
off retransmission as soon as the AuthenticatedGossiper is created.
This commit modifies the recently modified logic for self-channel
retransmission to exclude pruning *our* channels which haven’t been
updated since the broadcastInterval. Instead, we only re-broadcast
channels of ours that haven’t been updated in 24 hours.
This commit fixes an existing bug in the announcement processing of the
authenticated gossiper. We will now only examine an incoming
announcement for validity if it targets the chain that we’re currently
active on.
