In this commit, we lower the default CLTV delta from 144 (1 day) to 40
blocks (~7 hours). We do this as the initial value was purposefully very
high, and was only in place as place holder in earlier versions of the
software. Such a high value can also discourage path finding algorithms
from taking lnd paths due to the negative impact of CLTV value in widely
deployed heuristics.
In this commit, we update the `TestChanSyncFailure` method to pass given
the new behavior around updating borked channel states. In order to do
this, we add a new method to allow the test to clear an existing channel
state. This method may be of independent use in other areas in the
codebase in the future as well.
In this commit, we ensure that we mark the channel as borked before we
remove the link during the force close process. This ensures that if the
peer reconnects right after we remove the link, then it won't be loaded
into memory in `loadActiveChannels`. We'll now:
* mark the channel as borked
* remove the link
* read the channel state from disk
* force close
This ensures that the link (if it's active) is able to commit any
pending changes to disk before we read out the channel to force close.
In this commit, we add a new test: `TestForceCloseBorkedState`. This
ensures that it isn't possible to update the channel state once a
channel has been marked as borked. This assumes that all calls to
`ForceClose` will also mark the channel as borked. This isn't the case
yet, so this test fails as is.
When using the unit test flakehunter and specifying a package, after the
first successful run, all of the tests would be run, rather than just
the ones within the specified package.
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.
In this commit, we add two new address types to `NewAddressRequest`.
These address types will allow the caller to retrieve the last _unused_
address, rather than always rotating to the next address in the
keychain.
In this commit, we update the path finding logic to
ignore a channel if the HTLC value (including the fees
at the point) exceeds the max HTLC value (if set) of the
link.
Since the MaxHTLC field was recently added to the ChannelEdgePolicy struct,
and the Flags field was broken into ChannelFlags and MessageFlags, the
test edge policies should be updated accordingly.
In this commit, we rename the new `MaxHtlc` field to `MaxHtlcMsat`. We
do this in order to adhere to the new practice to suffix each amount
related field with their proper unit.
