In this commit, we update the funding workflow to be aware of the new
channel type that doesn't tweak the remote party's output within the
non-delay script on their commitment transaction. To do this, we now
allow the caller of `InnitChannelReservation` to signal if they want the
old or new (tweakless) commitment style.
The funding tests are also updated to test both funding variants, as
we'll still need to understand the legacy format for older nodes.
Checks that we get ErrDoubleSpend as expected when publishing a
conflicting mempool transaction with the same fee as the existing one,
and that we can publish a replacement with a higher fee successfully.
In this commit, we address an edge case that can happen a user rescans
w/ their seed, while retaining their existing `channel.db`. Once they
rescan, if they go to sign for a channel sweep for example, the
commitment key family (actually an account) may not yet have been
created, causing the signing attempt to fail.
We remedy this always creating the account if we go to sign, and the
account isn't found. The change has been structured to make this the
exception, so we'll avoid always needing to do 2 DB hits (check if
account exists, sign), each time we sign.
A new test has been added to exercise this behavior. If the diff from
the `signer.go` file is removed, then the test will fail.
In this commit, we fix a logic flaw in the testCreateSimpleTx test case
which emerged once we the bug fix for dust outputs landed. Before this
commit, we would erroneously fail during valid test execution.
In this commit, we add a new `LastUnusedAddress` method to the
`WalletController` interface. Callers can use this new method to graph
the last unused address, which can be useful for UIs that want to
refresh the address, but not cause nearly unbounded address generation.
The implementation for `btcwallet` uses the existing `CurrentAddress`
method. We've also added a new integration tests to exercise the new
functionality.
This commit is a step to split the lnwallet package. It puts the Input
interface and implementations in a separate package along with all their
dependencies from lnwallet.
This reverts commit 4aa52d267f.
It turns out that the other implementations set values for this field
which aren't based on the actual capacity of the channel. As a result,
we'll no reject most of their channel offerings, since they may offer a
value of a max `uint64` or something else hard coded that's above the
size of the channel. As a result, we're reverting this check for now to
maintain proper compatibility.
In this commit, we add a new test to the existing set of wallet tests to
ensure we can properly detect the confirmation of transactions that
spend our change outputs. We do this as a measure to prevent future
regressions from happening where the wallet doesn't request its backend
to be notified of when an on-chain transaction pays to a change address,
like with the recently discovered SendOutputs bug.
As is, this test will not pass until we update the btcwallet dependency
in the next commit.
In this commit, we add a new test to ensure that all backends will
properly send out notifications when an unconfirmed transcation that we
send is inserted into the tx store. Before we updated the btcwallet
build commit in dep, this would fail for neutrino but now passes.
In this commit, we add a new test to the set of lnwallet integration
tests. In this new test, we aim to ensure that all backends are able to
display unconfirmed transactions in ListChainTransactions. As of this
commit, this test fails as no backends will return unconfirmed
transactions properly.
In this commit, we add an additional degree of isolation to the set of
integration tests. A bug was recently fixed to ensure that the wallet
always starts rescans from _after_ it's birthday. In the past it would
miss some funds that were deposited _right_ before the birthday of the
wallet. Fixing this bug exposed a test flake wherein the btcd node would
itself rescan back and collect some of the funds that were last sent to
the bitcoind node.
In order to fix this, we now ensure that each backend will use a unique
HD seed such that the tests are still deterministic for each backend and
role.
In this commit, we introduce a nice optimization with regards to lnd's
interaction with a bitcoind backend. Within lnd, we currently have three
different subsystems responsible for watching the chain: chainntnfs,
lnwallet, and routing/chainview. Each of these subsystems has an active
RPC and ZMQ connection to the underlying bitcoind node. This would incur
a toll on the underlying bitcoind node and would cause us to miss ZMQ
events, which are crucial to lnd. We remedy this issue by sharing the
same connection to a bitcoind node between the different clients within
lnd.
In this commit, we fix an existing rounding related bug in the codebase.
The RPC interface for btcd and bitcoind return values in BTC rather than
in satoshis. So in several places, we're forced to convert ourselves
manually. The existing logic attempted to do this, but didn't properly
account for rounding. As a result, our values can be off due to not
rounding incorrectly.
The fix for this is easy: simply properly use btcutil.NewAmount
everywhere which does rounding properly.
Fixes#939.
This commit extends the amount of time we wait
for transaction to enter the mempool from
10 to 30 seconds. The wallet's interface tests
seem to be particularly slow when run with the
race flag, a problem which is only exacerbated
by the slowness of travis.
With 10s and the race flag, I was able to repro
the issues locally fairly consistently.
