This commit saves the RPC request used to construct the `Parameters` on
disk. Since it's a proto message, an easy way to read/write it is to
rely on the proto marshal/unmarshal methods. A side effect is that
migration also becomes easy as proto message have its own internal
mechanism to keep track of the compatibility.
This commit refactors the method `manager.SetParameters` to take a
`SetLiquidityParamsRequest`. As we'll see in the following commit, this
will enable us saving the params to disk more easily.
In this commit we add the version 3 htlc, which is implemented with
taproot script spending the two payment paths: the claim path case, and
the timeout case.
Since the code for creating and using a macaroon service is the same for
multiple projects (pool, loop, litd etc), the code has been unified in
lndclient. So this commit removes the macaroon service code and instead
uses the lndclient code.
Packages importing loopd can't import 2x looprpc packages (in the
form of swapserverrpc and looprpc). To get around this, we alias
each import with a different name, updating the server in this
commit.
Packages importing loopd can't import 2x looprpc packages (in the
form of swapserverrpc and looprpc). To get around this, we alias
each import with a different name, starting with the client in this
commit.
Protobuf does not allow naming conflicts for files within the same
process, because all proto messages register themselves in a global
registry.
This is problematic because the server's itests import the client's
looprpc package to make rpc queries to the loopd client, thus importing
duplicate common.proto and server.proto from the client's looprc package
(since they're both in there as well).
This change moves the server's proto files into their own directory so
that they are not imported when we want to use the client's files. We
cannot change the package name for the server, because that would be
a breaking change (the package name is included in URIS). Fortunately,
we have the go_package option which allows us to place generated files
in a different location.
This commit passes routehints all the way from when/if the user passes
them from the cli all the way to the backend loop server. If private is
used, this commit passes that boolean down to different stages, where it
is then converted into routehints.
main: add --private and --route_hints to quote
Adds --private and --route_hints flags to quote cli
In preparation for adding loop in swaps, we relate liquidity rules
to a specific type of swap that we want to dispatch. This allows us
to use a single rule format for multiple swap types.
To allow code with more up-to-date dependencies to import loop, we
bump our lndclient version. The minimum loop version remains 11.1
since we're not using any new apis.
This makes two changes to handling of errors when configuration file
could not be loaded:
1. Only NotFound errors are considered OK - access errors and other FS
issues are now treated as fatal.
2. Failing to load config file specified explicitly via `--configfile`
option is alway a fatal error.
Rationale: If the configfile was specified explicitly then it indicates
the user really wishes to load it. While the user could want it to be
optionally loaded for extra configuration options, this can be
accomplished using an empty file.
If the config file was not specified explicitly then its' path was
computed from loop directory. If the file is inaccessible due to
permissions or other FS errors it's nearly certain other following
operations will fail as well. Failing early with a clear message is thus
beneficial.
This still leaves room for uncaught user error (e.g. mistakenly naming
config file inside loop dir as `loop.conf` instead of `loopd.conf`) but
it's greatly reduced and such error should be easier to identify.

In this commit we add a call to the new probe endpoint directly into the
loop-in quote call. Furthermore we add an option to include private
channels in the loopin swap payment request. This is also useful for when
users quote/probe directly using the client API and specify hop hints.
There is an open issue for Python gRPC clients that is
currently being debugged grpc/grpc#23172
It can be mitigated server-side by specifying h2 in the metadata header.
The version v0.10.1-beta of lnd is quite old with v0.13.0-beta just
being published as RC2. Maintaining backward compatibility in the
lndclient library is quite an effort. We decided to merge the v0.11.1
branch into master meaning that all our projects now have this minimum
version requirement.
This commit bumps the _compile time_ version of lnd to v0.13.0-beta.rc2.
This does not have an effect on the user, the run time backward compatibility
will be preserved. Only the next commit will bump that minimum version.
