In this commit BOLT№2 retranmission logic for the channel link have
been added. Now if channel link have been initialised with the
'SyncState' field than it will send the lnwire.ChannelReestablish
message and will be waiting for receiving the same message from remote
side. Exchange of this message allow both sides understand which
updates they should exchange with each other in order sync their
states.
This commit where added as a measure to avoid the panic during several
server simultanoius fault. The panic happened becuase *t.Testing
structure is not concurrent safe.
In this commit, we address a lingering TODO within the
TestUpdateForwardingPolicy test case to ensure that Bob will reject the
payment the second time around due to an update in his fee policy.
In this commit, we update the TestLinkForwardTimelockPolicyMismatch to
instead _subtract_ time from the first HTLC extended to the initial
hop. We now subtract instead as giving intermediate hops more time
is.now permitted.
This commit adds a new test case for the default implementation of the
ChannelLink to ensure that the bandwidth is updated properly in the
face of commitment transaction overflows, and the subsequent draining
of said overflown commitment transaction.
This commit adds a new test for the current default ChannelLink
implementation to ensure that the bandwidth updates for a link are
externally consistent from the PoV of callers after a modifying action.
This commit temporary increases the timeout for the
TestChannelLinkBidirectionalOneHopPayments test in order to account for
the slowness of the travis instances that our tests are run on.
This commit modifies the TestChannelLinkBidirectionalOneHopPayments
test to ensure that each payment sent is safely above the dust
threshold. Note that the dust threshold itself is now higher due to the
existence of the HTLC covenant transactions which the HTLC values
themselves must cover.
This change ensure that this test operates under “normal” operation
conditions in order to catch any bugs introduced during a major change.
Within the network, it's important that when an HTLC forwarding failure
occurs, the recipient is notified in a timely manner in order to ensure
that errors are graceful and not unknown. For that reason with
accordance to BOLT №4 onion failure obfuscation have been added.
In this commit usage of the pending packet queue have been added.
This queue will consume the downstream packets if state machine return
the error that we do not have enough capacity for htlc in commitment
transaction. Upon receiving settle/fail payment descriptors - add htlc
have been removed, we release the slot, and process pending add htlc
requests.
Step #5 in making htlcManager (aka channelLink) testable:
Combine all that have been done so far and add test framework for channel
links which allow unit test:
* message ordering
* detect redundant messages
* single hop payment
* multihop payment
* several cancel payment scenarios
