In this commit, we remove the per channel `sigPool` within the
`lnwallet.LightningChannel` struct. With this change, we ensure that as
the number of channels grows, the number of gouroutines idling in the
sigPool stays constant. It's the case that currently on the daemon, most
channels are likely inactive, with only a hand full actually
consistently carrying out channel updates. As a result, this change
should reduce the amount of idle CPU usage, as we have less active
goroutines in select loops.
In order to make this change, the `SigPool` itself has been publicly
exported such that outside callers can make a `SigPool` and pass it into
newly created channels. Since the sig pool now lives outside the
channel, we were also able to do away with the Stop() method on the
channel all together.
Finally, the server is the sub-system that is currently responsible for
managing the `SigPool` within lnd.
Returns a brief json summary of each utxo found by calling
ListUnspentWitness in the wallet. The two arguments are the
minimum and maximum number of conrfirmations (0=include
unconfirmed)
One way applications built on top of lnd can estimate sync percentage is
through comparing the current time to the best known timestamp of the
lnd wallet's sync state. Therefore, we should always return this
information even if the the wallet is not synced.
In this commit, we add an additional check to btcwallet's IsSynced
method to ensure that it is not currently undergoing a rescan. We do
this to block upon starting the server and all other dependent
subsystems until the rescan is complete.
In this commit, we add the lightning address scope before the wallet
starts to prevent a race condition between the wallet syncing and adding
the scope itself. This became more apparent with the recent btcwallet
fixes, as several database transactions now occur between the wallet
being started and it syncing.
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 an additional check to btcwallet's FetchInputInfo
method to ensure the output is actually under control of the wallet.
Previously, the wallet would assume the output was under its control if
the txid of the output was found within the wallet. This is not a safe
assumption to make however, because if we happened to be the sender of
this transaction, it would be found within the wallet but it's not
actually under our control. To fix this, we explicitly check that there
exists an address in our wallet for this output.
This change was inspired by #1984 - the underlying call to
ListUnspent supports a (min, max) range so it makes sense that
the WalletController interface can also support this; a
default no-maximum can be expressed using a MaxInt32 value.
In this commit, we fix an existing bug wherein we wouldn't set the short
channel ID for the close summary in the database in the case that the
remote party force closed. The fix is simple, ensure that within
NewUnilateralCloseSummary we properly set the short channel ID. A test
has also been added in this commit, which fails without the
modifications to lnwallet/channel.go.
Fixes#2072.
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 fix a bug in the arguments to GetTransactions for the
btcwallet implementation of the WalletController interface. Before this
commit, we wouldn't properly return unconfirmed transactions. The issue
was that we didn't specify the special mempool height of "-1", as the
ending height. The mempool height is actually internally converted to
the highest possible height that can fit into a int32.
In this commit, we set the start to zero, and end to -1 (actually
2^32-1) to properly scan for unconfirmed transactions.
Fixes#1422.
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 fix a slight bug by ensuring that the revocation info
at the final state of the channel, as well as the local chan config is
properly set within the channel close summary created within
NewUnilateralCloseSummary. Before this commit, for all cooperative close
transactions, this state would _only_ include the pubkey itself, which
in some cases may not be sufficient to re-derive the key if needed.
