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.
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.
In this commit, we modify the existing `TestSendToRouteStructuredError`
test to return an error that doesn't trigger the second chance logic.
Otherwise, we'll get a nil failure result from the mission control
interpretation, meaning we won't exercise the full code path. Instead,
we use a terminal error to ensure that the expected code path is hit.
As is, this test will fail as a recent refactoring causes us to return a
`channeldb.FailureReason` error, since the newly added `handleSendError`
code path in the `SendToRoute` method will return the raw error, rather
than the `shardError`, which is of the expected type.
In this commit, in order to allow the test added in the prior commit to
pass, we'll increment the mockHTLCAmt value by 1 to ensure we never
attempt to add a zero value HTLC.
Fixes#5468
As is, if the remote party proposes a min HTLC of 0 `mSat` to us, then
we won't ever be able to _send outgoing_ in the channel as the
`MayAddOutgoingHtlc` will attempt to add a zero-value HTLC, which isn't
allowed within the protocol.
The default channels created actually already use a min HTLC value of
zero within the tests, so this test case fails as is.
As requested by users of node bundle software. They want to use the
wallet-unlock-password-file configuration option in their
default/template config file. This makes the first-time lnd setup a bit
more tricky since lnd will fail with an error if no wallet exists yet
while that config option is used.
The new wallet-unlock-allow-create option instructs lnd to not fail if
no wallet exists yet but instead spin up its unlocker RPC as it would
without the wallet-unlock-password-file being present.
This is not recommended for auto-provisioned or high-security systems
because the wallet creation RPC is unauthenticated and an attacker could
inject a seed while lnd is in that state.
To make it possible to use the wordlist used for aezeed outside of the
aezeed package we export certain properties of the word list and the
word list itself.
This commit adds two tests to check that a) the correct deadline is used
given different HTLC sets and b) when sweeping anchors the correct
deadlines are used.
