This commit adds a postgres store to the loopdb package.
Ths postgres migrator uses a replacer filesystem to replace the
sqlite types to postgres types in the migration.
This commit adds a batch insert to the interface. This greatly reduces
the time the migration will take. It is not implemented for the boltdb, as
we will not be supporting migrating to the boltdb.
This commit changes the stable protocol version to be the Musig2 protocol.
The experimental version is set to the stable version
in order for the flag to still work if a user has it set.
This commit adds a new struct to hold all HTLC keys and refactors the
SwapContract which is used by both loopin and loopout swaps to use this
new struct. The newly added internal keys will for now hold the script
keys to keep everything equivalent but are already stored and read back
if the protocol version is set to MuSig2.
This commit adds a new protocol version which will add MuSig2 loop in
and loop out using key reveal and extends the existing protocol with new
message members to be able to pass around htlc internal public keys.
The commit also fixes some minor formatting issues in the server proto.
This commit fixes outstanding linter issues, that we're not found by
running `make lint` locally. The linter issues were found by running
`docker run -v $(pwd):/build loop-tools golangci-lint run --whole-files`
I added the `revive` to the excludes as it would be to much of a
refactor and IMO seems unneccesary. E.g.
`interface.go:222:6: exported: type name will be used as
loop.LoopInTerms by other packages, and that stutters; consider
calling this InTerms (revive)`. I think `loop.LoopInTerms` is fine.
This commit adds a new bucket to save liquidity parameters. We've
skipped the serialization and deserialization implementations here and
leave them to be handled by the liquidity package.
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.
We already have a Label field in the embedded SwapContract
field for loop in swaps. This commit removes an erroneously
added Label field in LoopInContract which may be a cause of
ambiguity when referencing this field.
To make sure we don't just block for forever if another Loop daemon
process is already running, we add a timeout and error out if obtaining
the unique file lock fails after 5 seconds.
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).
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.
This commit bumps the current protocol version and integrates htlc v2
with loop in/out for new swaps, while keeping htlc v1 for any pending
swaps with previous protocol versions.
This commit adds the protocol version to each stored swap. This will be
used to ensure that when swaps are resumed after a restart, they're
correctly handled given any breaking protocol changes.
To allow users to specify differing confirmation targets, we store the
swap conf target per-swap. This makes us restart safe, so we do not
forget confirmation values for swaps that are in flight when we restart.
This commits adds an optional label to our swaps, and writes it to
disk under a separate key in our swap bucket. This approach is chosen
rather than an on-the-fly addition to our existing swap contract field
so that we do not need to deal with EOF checking in the future. To allow
creation of unique internal labels, we add a reserved prefix which can
be used by the daemon to set labels that are distinct from client set
ones.
A database field was already in place to allow channel selection for
loop in. Unfortunately this field, which contains a short channel id,
isn't easily usable for controlling the loop server payment. Because of
non-strict forwarding, it is only possible to constrain a route to a
specific last hop pubkey.
This commit converts the existing field into a pubkey field.
