This commit removes the mutex from ClientStats and instead puts that in
clientStats which wraps ClientStats with a mutex. This is so that the
tower client interface can return a ClientStats struct without worrying
about copying a mutex.
Simiarly to the previous commit, this commit moves the RemoveTower
method from the Client to the TowerClientManager interface. The manager
handles any DB related handling. The manager will first attempt to
remove the tower from the in-memory state of each client and then will
attempt to remove the tower from the DB. If the removal from the DB
fails, the manager will re-add the tower to the in-memory state of each
client.
In this commit we move the AddTower method from the Client interface to
the TowerClientManager interface. The wtclientrpc is updated to call the
`AddTower` method of the Manager instead of calling the `AddTower`
method of each individual client. The TowerClient now is also only
concerned with adding a new tower (or new tower address) to its
in-memory state; the tower Manager will handle adding the tower to the
DB.
The docker image have been updated so we are using another protobuf
version to generate the files. The generate files include the version of
the compiler used to creating them, so we need this commit to pass the
`rpc-check` step in our CI.
Add a new `exclude_exhausted_sessions` field to the relevant
wtclient.proto requests. This was chosen instead of "include_exhausted"
so as to not break the API.
Prior to this commit, the wtclient would request tower info from both
the legacy client and the anchors client and would then merge the
results returned. This is incorrect since the two clients will have
different session info and different "active" statuses for the same
tower. This commit thus ensures that we dont lose this info.
Use kvdb package v1.4.1. This update also forced the protobuf version to
be bumped which required `make rpc` to be run to update the generated
files. This also required a bump in the github pinned dependencies
config for the grpc and protobuf libs.
In this commit, a migration is done that takes all the AckedUpdates of
all sessions and stores them in the RangeIndex pattern instead and
deletes the session's old AckedUpdates bucket. All the logic in the code
is also updates in order to write and read from this new structure.
In this commit, we start making use of the new ListClientSession
functional options added in the previous commit. We use the functional
options in order to calculate the max commit heights per channel on the
construction of the tower client. We also use the options to count the
total number of acked and committed updates. With this commit, we are
also able to completely remove the AckedUpdates member of the
ClientSession since it is no longer used anywhere in the code.
This commit was previously split into the following parts to ease
review:
- 2d746f68: replace imports
- 4008f0fd: use ecdsa.Signature
- 849e33d1: remove btcec.S256()
- b8f6ebbd: use v2 library correctly
- fa80bca9: bump go modules
As a preparation for the migration to the grpc-gateway/v2 library we
declare each service's REST annotations in its own file. This is
optional in the v1 library but mandatory in v2.
We'd never decrement the number of pending backups upon a watchtower
accepting one, making it confusing for users to determine whether their
backups have actually been accepted. Along the way, we also rename
NumTasksReceived to NumTasksPending to better reflect its purpose.
This commit deprecates/replaces the old field `sat_per_byte` with
`sat_per_vbyte`. While the old field suggests sat per byte, it’s
actually using sat per virtual byte. We use the Hidden param to hide all
the deprecated flags. These flags won't show up in help menu onwards,
while stay valid that can be passed from cli. Thus bash scripts
referencing these fields won't be broken.
In order to be able to register the subservers with the root grpc server
before we have all dependencies available, we wrap them in an
GrpcHandler struct. This struct will initially hold an empty reference
to the subservers, which allows us to register with the GRPC server, and
later populate and create the subserver instance.
The logger string used to identify the wtclient and wtclientrpc loggers
was the same, leading to being unable to modify the log level of the
wtclient logger as it would be overwritten with the wtclientrpc's one.
To simplify things, we decide to use the existing RPC logger for
wtclientrpc.
We now use the jsonpb marshaler to convert the RPC responses to
JSON in lncli and REST. The jsonpb has a setting to use the
original name as defined in the proto file and the explicit
json_name definition is not necessary any more.
The jsonpb setting is called OrigName and needs to be true.
