This commit removes the activeNetParams global in chainparams.go. This
is necessary to isolate code from the lnd package so we can import it
for use in tests, other projects, etc.
In this commit, we split the database storage into two classes: remote
and local data. If etcd isn't active, then everything is actually just
local though we use two pointers everywhere. If etcd is active, then
everything but the graph goes into the remote database.
There seems to be a misinterpretation of a variable between the
btcwallet and gozmq libraries. When establish a ZMQ connection, it
expects a timeout, which is used to set read deadlines and determine how
long we should wait before attempting a reconnection. Within btcwallet
and lnd however, this is is interpreted as a polling duration,
explaining the current value of 100ms. Under load, especially on
less-capable hardware, this leads to high resource usage as we get into
a constant reconnection loop. To remedy this, we use a timeout of 5s
instead, which is a much more reasonable value for read timeouts, and is
also what's used for LN peers.
In this commit, we create a new chainfee package, that houses all fee
related functionality used within the codebase. The creation of this new
package furthers our long-term goal of extracting functionality from the
bloated `lnwallet` package into new distinct packages. Additionally,
this new packages resolves a class of import cycle that could arise if a
new package that was imported by something in `lnwallet` wanted to use
the existing fee related functions in the prior `lnwallet` package.
To avoid the ChainService still attempting to access the database when
it gets closed, re-order the stop order such that the Chainservice gets
stopped before closing the DB.
In this commit, we fix an oversight that overrode the default ban
duration for neutrino to 5s from the default 24 hrs. We correct this by
raising the ban duration to 48hrs. In the future in order to ignore
these peers persistently, we'll need to start to persist our ban list.
However that's a change for another time.
In this commit, we upgrade regular KeyRing instance to a SecretKeyRing
instance as we need the upgraded instance in order to recover SCB's. Due
to the fact that we don't currently store the full KeyLocator for the
key used to derive a shachain root for each channel, we instead need to
obtain the private key vanilla to re-derive this value.
