This commit attempts to make the polling logic in sweeper more linear.
Previously, the sweep's timer is reset/restarted in multiple places,
such as when a new input comes in, or a new block comes in, or a
previous input being spent, making it difficult to follow. We now remove
the old timer and replaces it with a simple polling logic - we will
schedule sweeps every 5s(default), and if there's no input to be swept,
we'd skip, just like the previous `scheduleSweep` does.
It's also worthy noting that, although `scheduleSweep` triggers the
timer to tick, by the time we do the actual sweep in `sweepCluster`,
conditions may have changed. This is now also fixed because we only have
one place to create the clusters and sweeps.
This commit refactors some of the bookkeeping around the ping logic
inside of the Brontide. If the pong response is noncompliant with
the spec or if it times out, we disconnect from the peer.
This change makes the generation of the ping payload a no-arg
closure parameter, relieving the pingHandler of having to
directly monitor the chain state. This makes use of the
BestBlockView that was introduced in earlier commits.
In this commit we change how we select invoices to follow or delete when
starting the InvoiceRegistry to instead of using the deperecated scan
func from channeldb, use specific functions to gather pending and delete
canceled invoices.
This commit makes sure an input is only added to the cluster when it has
successfully estimated its fee rate. Previously, when an error is
returned from `feeRateForPreference`, we'd still add this input to the
cluster, resulting a **lower** fee rates being used because when
averaging the fee rates, we'd think this input has zero fee rate
specified.
An unit test is patched to make the method `clusterByLockTime` more
robust.
* sweep: use longer variable name for clarity in `addToState`
* sweeper: add more docs and debug logs
* sweep: prioritize smaller inputs when adding wallet UTXOs
This commit sorts wallet UTXOs by their values when using them for
sweeping inputs. This way we'd avoid locking large UTXOs when sweeping
inputs and also provide an opportunity to aggregate wallet UTXOs.
* contractcourt+itest: relax anchor sweeping for CPFP purpose
This commit changes from always sweeping anchor for a local force close
to only do so when there is an actual time pressure. After this change,
a forced anchor sweeping will only be attempted when the deadline is
less than 144 blocks.
* docs: update release notes
* itest: update test `testMultiHopHtlcLocalChainClaim` to skip CPFP
Since we now only perform CPFP when both the fee rate is higher and the
deadline is less than 144, we need to update the test to reflect that
Bob will not CPFP the force close tx for the channle Alice->Bob.
* itest: fix `testMultiHopRemoteForceCloseOnChainHtlcTimeout`
* itest: update related tests to reflect anchor sweeping
This commit updates all related tests to reflect the latest anchor
sweeping behavior. Previously, anchor sweeping is always attempted as
CPFP when a force close is broadcast, while now it only happens when the
deadline is less than 144. For non-CPFP purpose sweeping, it will happen
after one block is mined after the force close transaction is confirmed
as the anchor will be resent to the sweeper with a floor fee rate, hence
making it economical to sweep.
