To itest our autolooper, we need to be able to trigger dispatch on
demand. This functionality is included in a separate rpc server behind
a dev flag. Since it is unlikely that we need to split loop into
multiple rpc servers, this commit simply adds an additional debug server
rather than opting for a full subserver setup.
We update to the latest lndclient that now requires a label when
publishing an on-chain transaction. Instead of just adding an empty
string, we use the proper labels added in a previous commit.
Add a dated fee budget to our swap suggestions. This budget only applies
to automatically dispatched swaps (which will be added in later
commits). We choose to apply the fee budget to our suggestions so that
they perfectly replicate what the autolooper would do. The budget has a
start date so that it can be refreshed once it has been used up over a
period (rather than having to endlessly increase it).
As we add more parameters in this PR, we wil want to test values
beyond our default values. This commit updates the suggest swaps test
helper to take a full setup struct, and adds a default set of channels
and rules which will be used in the absense of this setup struct.
Previously labels with reserved prefixes were added to provide us
with a way to identify automatically dispatched loops. This commit moves
the validation of these labels to the rpc level so that it will only
apply to user-initiated swaps.
As we add more paramters to the liqudity manager, it will become more
difficult to include them in a single cli endpoint with rules. This
commit renames the existing setparam command (which is only used for
rules at present), so that we can have a dedicated paramters cli
command for all the new values we are adding.
To decide whether we event want to attempt a swap, we add a fee limit
that we check against our estimate for the current number of
confirmations we want our sweep to confirm in. If fees are higher than
this limit, we do not suggest swaps.
This commit updates swap suggestions to return loop out requests with
sufficient fields populated so that a loop out can directly be
dispatched from a suggestion. This requires setting of fees an min
sweep conf targets (our htlc conf target and addresss will be set by
the daemon's client rpc server if we do not provide them). We also do
some test refactoring so that we can more easily test the suggest swaps
endpoint.
To make sure we can use the latest version of loop in LiT, we need to
make sure loop compiles against the actual v0.11.1 branch of lnd. There
were some conflicting changes to the macaroon service that didn't make
it to the branch that we need to roll back. Those changes don't affect
loop at all as we were always using the default root key ID anyway.
