In this commit, we introduce a delta from the on-chain HTLC's
expiration. Since clients are now able to specify a confirmation target
for the HTLC sweep, it's possible that the sweep doesn't confirm within
the intended target in the event of an increasing demand for block
space. Once the delta from the HTLC's expiration is reached, we'll begin
to use the default sweep confirmation target when sweeping the HTLC,
which should provide a timely confirmation. This is needed because if
the preimage has already been revealed, then we need to make sure we
sweep the HTLC before the server does.
Previous code in log.go assumed there would by sub system level
enable/disable for loop. This is not yet in place, so converting to same
style as used in the lndclient package.
* Introduced docker integration
* Added Dockerfile to build loopd and loop with no dependencies.
* Added instructions to build and run docker image.
* Fixed documentation on mapping of ~/.lnd
* Would have caused problems because ~/.loop wasn't mapped
* Now map entire home directory
* Updated DOCKER.md example to just map ~/.lnd and ~/.loop.
* Removed mapping of home directory - one of the benefits of docker is being explicit about the resources the container uses so I felt bad mapping the entire home directory when only two known folders were used.
This commit fixes the generation of the htlc address. This bug didn't
affect the swap execution, because the htlc address is only used for
display to the user/caller.
In this commit, we modify all sub-servers as well as the main lnd gRPC
service to use a macaroon per call rather than a connection level
macaroon. The old approach would result in us using the same macaroon
for the entire connection, while this new approach allows us to use
multiple macaroons with a single connection.
We move to this new approach as it doesn't require users to delete their
admin macaroon before being able to use Loop. It also preps us for a
future where there is no admin macaroon, and we instead need to use a
set of macaroons to accomplish our tasks.
In this commit, we modify the `NewLndServices` method to accept the
directory where macaroons are stored, rather than the path for the admin
macaroon. This is a prep to moving towards a multi-macaroon system, as
the `macaroonPouch` will handle storing the various macaroons.
In this commit, we add a new struct, the `macaroonPouch`. This struct
bundles all the macaroons we need for each sub-server. Along the way, we
also export the set of default* paths for lnd, and add a new set of
variables that store the default file names of each of the macaroons for
each sub-server.
The `WithMacaroonAuth` method on the `serializedMacaroon` type will
allow us to attach a macaroon for each call rather than attaching it at
the connection level. This slight change will allow us to use multiple
macaroons over a single RPC connection, rather than a single global
macaroon.
