In this commit, we modify the Node interface to return a set of raw
bytes, rather than the full pubkey struct. We do this as within the
package, commonly we only require the pubkey bytes for fingerprinting
purposes. Before this commit, we were forced to _always_ decompress the
pubkey which can be expensive done thousands of times a second.
In this commit, we add a quit channel to the AddMsg method of the
msgStream struct. Before this commit, if the queue was full, the
readHandler would block and be unable to exit. We remedy this by
leveraging the existing quit channel of the peer as an additional select
case within the AddMsg method.
This commit fixes a bug in the integration test, that
reliably fails after disabling the height hint cache.
The test originally asserted that the htlc funds were
in limbo, but was reading a stale copy of the force
close information. Recently, the test was amended to
provided a valid read of the force close in
96a079873a6da2f0a93adc30945971fc07c5e610. However,
the issue was not apparent until build against the
disabled height hint cache.
The test is now correct to assert that there are no
funds in limbo, as the commitment output has been
swept, but the htlcs are still in the contract
court, so the nursery is unaware of them. We also
add another sanity check to validate that there are
no pending htlcs on the force close at that point
in time.
In this commit, we select on the peer's QuitSignal to allow the caller
to unblock if the peer itself is disconnecting. With this change, we now
ensure that it isn't possible for a peer to block on this method and
prevent a graceful exit.
In this commit, we extend the Peer interface with a new QuitSignal
method. This method is meant to expose a read-only quit channel which
will allow callers to cancel any actions based on the lifetime of the
underlying peer.
In this commit, we thread through the quit of the peer to the execution
of the apply function for a msgStream. This change ensures that if the
target is still processing the message, then the peer is able to exit
cleanly and not block insensately.
In this commit, we add a caller quit channel to waitUntilChannelOpen.
This ensures that the caller won't block forever if it needs to exit
before the funding manager exits, or the channel barrier is actually
closed.
In this commit we move the atomic var increment that signals the
consumer goourtine has exited to the top of the method in a defer
statement. This cleans up some duplicate code and also adheres to the
pattern of using defers to signal cleaning up any dependent goroutine
state on exit.
In this commit, we raise the readHandler wait group done into a defer
statement at the top of the method. This fixes an existing but that
would cause the readHandler to declare it had exited, yet possibly still
be waiting on the chan message stream below to exit.
In this commit, we increase the fwdpkg gc interval
to avoid having it conflict with switch tests that
inspect forwarding packages. The current timeout is
a little too short on travis, and sporadically fails
TestChannelLinkCleanupSpuriousResponses, which was
added recently.
In this commit, we address a bug where it's possible that we still
attempt to manually scan for a transaction to determine whether it's
been included in the chain even after successfully checking the txindex
and not finding it there. Now, we'll short-circuit this process by
exiting early if the txindex lookup was successful but the transaction
in question was not found. Otherwise, we'll fall back to the manual
scan.
