We change how the `bitcoind` node connects to the miner by creating a
temp RPC client and use it to connect to the miner. In addition we also
assert the connection is made.
This commit adds a script to hunt flakes for a specific unit test with
trace logs. Also rename the make commands to make them more clear on
whether it's a unit test, itest, or paralleled itest.
The exposed AddNode, AddEdge and UpdateEdge methods of the Builder are
currently synchronous since even though they pass messages to the
network handler which spins off the handling in a goroutine, the public
methods still wait for a response from the handling before returning.
The only part that is actually done asynchronously is the topology
notifications.
We previously tried to simplify things in [this
commit](d757b3bcfc)
but we soon realised that there was a reason for sending the messages to
the central/synchronous network handler first: it was to ensure
consistency for topology clients: ie, the ordering between when there is
a new topology client or if it is cancelled needs to be consistent and
handled synchronously with new network updates. So for example, if a new
update comes in right after a topology client cancels its subscription,
then it should _not_ be notified. Similariy for new subscriptions. So
this commit was reverted soon after.
We can, however, still simplify things as is done in this commit by
noting that _only topology subscriptions and notifications_ need to be
handled separately. The actual network updates do not need to. So that
is what is done here.
This refactor will make moving the topology subscription logic to a new
subsystem later on much easier.
Turns out that actions/setup-go starting with @v4 also adds caching.
With that, our cache size on disk has almost doubled, leading to the
GitHub runner running out of space in certain situation.
We fix that by disabling the automated caching since we already have our
own, custom-tailored version.
For the lncli cmd we now always initiate the coop close even if
there are active HTLCs on the channel. In case HTLCs are on the
channel and the coop close is initiated LND handles the closing
flow in the background and the lncli cmd will block until the
transaction is broadcasted to the mempool. In the background LND
disallows any new HTLCs and waits until all HTLCs are resolved
before kicking of the negotiation process.
Moreover if active HTLCs are present and the no_wait param is not
set the error msg is now highlightning it so the user can react
accordingly.
Before this commit, the only error returned from `IsOurTx` is when the
root bucket was not created. In that case, we should consider the tx to
be not found in our db, since technically our db is empty.
A future PR may consider treating our wallet as the single source of
truth and query the wallet instead to check for past sweeping txns.
Previously, when a given input is found spent in the mempool, we'd mark
it as Published and never offer it to the fee bumper. This is dangerous
as the input will never be fee bumped. We now fix it by always
initializing the input with state Init, and only use mempool to check
for fee and fee rate.
This changes the current restart behavior - as previously when a
sweeping tx is broadcast, the node shuts down, when it starts again, the
input will be offered to the sweeper again, but not to the fee bumper,
which means the sweeping tx will stay in the mempool with the last-tried
fee rate. After this change, after a restart, the input will be swept
again, and the fee bumper will monitor its status. The restart will also
behave like a fee bump if there's already an existing sweeping tx in the
mempool.
This commit handles the case when the input is missing during the RBF
process, which could happen when the bumped tx has inputs being spent by
a third party. Normally we should be able to catch the spend early via
the spending notification and never attempt to fee bump the record.
However, due to the possible race between block notification and spend
notification, this cannot be guaranteed. Thus, we need to handle the
case during the RBF when seeing a `ErrMissingInputs`, which can only
happen when the inputs are spent by others.
This commit refactors `handleInitialTxError` and `createAndCheckTx` to
take a `monitorRecord` param, which prepares for the following commit
where we start handling missing inputs.
This is a minor refactor so the `createAndPublishTx` flow becomes more
clear, also prepares for the following commit where we start to handle
missing inputs.
We now rename "third party" to "unknown" as the inputs can be spent via
an older sweeping tx, a third party (anchor), or a remote party (pin).
In fee bumper we don't have the info to distinguish the above cases, and
leave them to be further handled by the sweeper as it has more context.
This commit refactors the `processRecords` to always handle the inputs
spent when processing the records. We now make sure to handle unknown
spends for all backends (previously only neutrino), and rely solely on
the spending notification to give us the onchain status of inputs.
This commit restricts the graph CRUD interface such that one can only
add a proof to a channel announcement and not update any other fields.
This pattern is better suited for SQL land too.
This commit fixes a bug that would check that the passed `edge` argument
of UpdateChannelEdge is nil but it should actually be checking if the
`edges` bucket is nil.
In this commit, we use the available kvdb `View` method directly for
starting a graph session instead of manually creating and commiting the
transaction. Note this changes behaviour since failed tx create/commit
will now error instead of just log.
In this commit, we add a `GraphSession` method to the `ChannelGraph`.
This method provides a caller with access to a `NodeTraverser`. This is
used by pathfinding to create a graph "session" overwhich to perform a
set of queries for a pathfinding attempt. With this refactor, we hide
details such as DB transaction creation and transaction commits from the
caller. So with this, pathfinding does not need to remember to "close
the graph session". With this commit, the `graphsession` package may be
completely removed.
