In this commit, we add a simple bash script to parse out the current PR
number from an environment variable in the GH actions context, and use
that to check to see if the PR has been referenced in the release notes
or not. This isn't 100% fool proof, but it should catch most of the
common cases.
This commit removes an assertion which is not needed because with etcd
we can safely create keys and values with the same key since they are
stored under different keys in the DB. This saves us one unnecessary Get
on every Put.
The etcd cursor Delete stepped to the next item in the range before
Delete to not invalidate the iteation. This is unnecessary and not
compatible with bbolt, resulting in an extra fetch too.
In this commit, we attempt to fix a race condition that may occur in the
current AMP and MPP tests.
It appears the following scenario is possible:
* The `mppTestContext` [is used to create 6 channels back to
back](https://github.com/lightningnetwork/lnd/blob/master/lntest/itest/lnd_amp_test.go#L43)
* The method used to create the channel ends up calling
[`openChannelAndAssert`](edd4152682/lntest/itest/lnd_mpp_test.go (L300))
which'll open the channel, mine 6 blocks, [then ensure that the
channel gets
advertised](edd4152682/lntest/itest/assertions.go (L78))
* Later on, [we wait for all nodes to hear about all channels on the
network
level](https://github.com/lightningnetwork/lnd/blob/master/lntest/itest/lnd_amp_test.go#L62)
I think the issue here is that we'll potentially already have mined 30
or so blocks before getting to the final nodes, and those nodes may have
already heard about the channel already. This may then cause their
[`lightningNetworkWatcher`](edd4152682/lntest/node.go (L1213))
goroutine to not properly dispatch this, since it's assumed that the
channel hasn't been announced (or notified) when the method is called.
One solution here is to just check if the channel is already in the
node's graph or not, when we go to register the notification. If we do
this in the same state machine as the watcher, then we ensure if the
channel is already known, the client is immediately notified. One thing
that can help us debug this more in the future is adding additional
logging in some of these helper goroutines so we can more easily track
the control flow.
This commit implements this solution by checking to ensure that the
channel isn't already known in our channel graph before attempting to
wait for its notification, as we may already have missed the
notification before this registration request came in.
This commit creates the file lnd_misc_test.go to hold all miscellaneous
tests in the file lnd_test.go. From now on, the lnd_test.go will only be
responsible for handling the "top" level functionalities such as
splitting test cases and run them. Newly created test cases should find
their places in the related test files, or create new one when needed.
This commit refactors the function assertNumConnections to use
wait.NoError. Prior to this commit, `make lint` will fail on this
function. While fixing it, it's noticed that wait.NoError suits the
case so it's refactored to use it.
From bbolt docs:
// Seek positions the cursor at the passed seek key. If the key does not exist,
// the cursor is moved to the next key after seek. Returns the new pair.
In this commit, we fix a regression introduced by a recent bug fix in
this area. Before this change, we'd inspect the error returned by
`processSendError`, and then fail the payment from the PoV of mission
control using the returned error.
A recent refactoring removed `processSendError` and combined the logic
with `tryApplyChannelUpdate` in order to introduce a new
`handleSendError` method that consolidates the logic within the
`shardHandler`. Along the way, the behavior of the prior check was
replicated in the form of a new internal `failPayment` closure. However,
the new function closure ends up returning a `channeldb.FailureReason`
instance, which is actually an `error`.
In the wild, when `SendToRoute` fails due to an error at the
destination, then this new logic caused the `handleSendErorr` method to
fail with an error, returning an unstructured error back to the caller,
instead of the usual payment failure details.
We fix this by no longer checking the `handleSendErorr` for an error as
normal. The `handleSendErorr` function as is will always return an error
of type `*channeldb.FailureReason`, therefore we don't need to treat it
as a normal error. Instead, we check for the type of error returned, and
update the control tower state accordingly.
With this commit, the test added in the prior commit now passes.
Fixes#5477.
