In this commit BOLT#4 specification message have been added to the
lnwire package. This messsage is needed in order to notify payment
sender that forwarding node unable to parse the onion blob.
In this commit onion routing error from BOLT#4 have been added, the
initial error construction have been splitted on two parts: The first
part which contains the actual data will reside inside the lnwire
package because it contains all necessary function to decode/encode
the data. The second part obfuscation and hmac checking will resides
inside the lighting-onion package because it requires the key
generation.
The latest builds of neutrino and btcwallet include a number of
performance optimizations that should speed up the sync of neutrino
nodes while ensuring all the pessary data is in place for re-org
safety.
This commit fixes a possible panic within the funding manger’s workflow
for pending channels. We now ensure that the local discovery signal
retrieved from the localDiscoverySignals map is always non-nil.
Otherwise, we risk a server panic in the case that a node retransmits
the FundingLocked message after a channel has been fully processed, or
even just sends a FundingLocked message for a non-existent channel.
This commit adds the possibility for the initiator of a
channel to send the update_fee message, as specified
in BOLT#2. After the message is sent and both parties
have committed to the updated fee, all new commitment
messages in the channel will use the specified fee.
This new build of lightning-onion includes the routines necessary to
implement the encryption and decryption of HTLC errors as defined
within the specification.
Support for regtest allows us to create integration tests to verify
interoperability with other implementations. This seems to work, and
allows to connect to `btcd` and indirectly to `bitcoind` so we can run
lnd on the same network as eclair and c-lightning.
For details about my integration framework check this repo:

A rather nasty re-org related bug was recently fixed in the upstream
version of roasbeef’s btcwallet. In order to fix this within the main
lnd build, we update the glide files such that the latest changes will
be pulled in.
This commit fixes a minor bug in the goroutine that’s launched to check
the sync status of a particular node. Previously, the goroutine could
end up infinitely stuck on a send as once the chain has been detected
as synced, it didn't exit.
We fix this now by ensure that the goroutine always terminates after
the initial notification to the caller. Additionally, we not ensure
that both the internal and exterior goroutine are both reading off of
the peer’s quit channel.
If an HTLC’s value is below a node’s dust limit, the amount for that
HTLC should be applied to to the fee used for the channel’s commitment
transaction.
This commit modifies the travis build script, and our local test script
to ensure that the race condition builds are conducted in a parallel
build. After this commit two travis builds will be kicked off for each
push/commit: one that runs the race condition tests in isolation, and
another that runs the integration tests then the coverage tests.
In order to do the above cleanly, the integration tests are now guarded
behind a build flag. In order to run the integration tests, one now
needs to specify the `-tags rpctest` flag when running the `go test`
command.
This commit fixes a regression introduce in the prior commit which
added full verification of the per-hop payloads to the ChannelLink
interface. When this was initially implemented, the added checks
weren’t guarded on the existence of debughtlc’s. As a result,
debughtlc’s would be rejected as they don’t match the expected invoice
value.
This commit fixes that issue by only checking the hop payload if debug
HTLC mode isn’t on.
A prior commit modified the walletbalance RPC to return satoshi instead
of BTC. As a result, we need to update the SetUp method in the
networkHarness to ensure we expect the proper value when asserting
wallet balances.
The btclog package has been changed to defining its own logging
interface (rather than seelog's) and provides a default implementation
for callers to use.
There are two primary advantages to the new logger implementation.
First, all log messages are created before the call returns. Compared
to seelog, this prevents data races when mutable variables are logged.
Second, the new logger does not implement any kind of artifical rate
limiting (what seelog refers to as "adaptive logging"). Log messages
are outputted as soon as possible and the application will appear to
perform much better when watching standard output.
Because log rotation is not a feature of the btclog logging
implementation, it is handled by the main package by importing a file
rotation package that provides an io.Reader interface for creating
output to a rotating file output. The rotator has been configured
with the same defaults that btcd previously used in the seelog config
(10MB file limits with maximum of 3 rolls) but now compresses newly
created roll files. Due to the high compressibility of log text, the
compressed files typically reduce to around 15-30% of the original
10MB file.
This commit fixes a send on closed channel panic by adding additional
synchronization when cancelling the notifications for a particular
topology client. We now ensure that all goroutines belonging to a
particular topology client exit fully before we close the notification
channel in order to avoid a panic.
This commit fixes a race condition that would at times occur in the
htlcswitch.TestChannelLinkBidirectionalOneHopPayments test case. A race
condition would occur in the goroutine running ReceiveNewCommitment
compared with the grouting that would obtain the snapshot in order to
make a forwarding decision.
We fix this by creating a new public key for each new commitment
transaction such that we complete avoid the read/write race condition.
This commit increases the history size of the race condition detector
such that we will more reliably be able to recover the stack in the
case that a race condition occurs.
This commit fixes a bit of a wart in the configuration file handling
wherein if the config file isn’t found, an error was printed to stderr.
At times, this would cause the testing framework to erroneously mark as
test as failed. Instead, we now keep a particular config file error,
and check that, printing to a warning log level.
