2023-08-24Rework vehicle signals support to use KUKSA.val databrokerScott Murray7-434/+846
Rework the VehicleSignals class and its use in the Navigation and Hvac classes to switch from using the original KUKSA.val server via WebSockets to the KUKSA.val databroker's gRPC "VAL" API. Notable changes: - The VehicleSignals API has changed a bit with respect to setting signals, callers now need to pass the new value as the type that matches the signal as opposed to always passing a string, and optionally indicate if an actuator's target or value is being set. Subscribe operations now also allow subscribing for either actuator targets or values. - It is possible that the values returned by get and subscribe operations will be changed to using QVariant instead of QStrings in a future follow up, but that has not been done in these changes. - The connected signal from VehicleSignals still has roughly the same meaning, but the authorize function and authorized signals are to some degree redundant now. They have been kept for compatibility, but may be removed in a follow up set of changes. - The section header in the .ini files expected by the VehicleSignalsConfig class has been changed from "vis-client" to "kuksa-client" since the databroker is not a VIS server, and to some degree forcing an update on the part of clients is useful since their authorization tokens also need to change. - The client key and certificate support has been removed from the VehicleSignalsConfig class, as they are no longer used in either the server or databroker as of KUKSA.val 0.4.0. A new optional parameter, "tls-server-name", has been added to work with the new TLS support behavior. It can be used to override the expected host name for connecting to a non-local databroker instance. - The Navigation constructor now takes an additional parameter to indicate whether the instance acts as a router or a client. The underlying need for this stems from an application acting as a router needing to subscribe to the destination setting actuator targets.

2022-12-30vehicle-signals: Increase double value precisionScott Murray1-1/+1
The code for double values for VSS signals was using the default Qt double to string conversion, which defaults to a max of 6 decimal places, explicitly format with 9 so that latitude and longtitude values for the navigation related signals do not get truncated.

2022-09-10Add applaunchd gRPC API wrapperScott Murray2-31/+0
Changes: - Add applaunchd gRPC API wrapper in applauncher directory, clients can include AppLauncherClient.h to use it. - To facilitate generating protobuf and gRPC code with protoc, switch from CMake to meson for building. While the code generation can be done in CMake, it is a lot more straightforward with meson, and if use of this library continues meson will be easier to maintain. Known issues: - The behavior of the client implementation here with respect to the server side (i.e. applaunchd) going away is currently robust, but could stand improvement with some further investigation. As the code stands, starting applications works when applaunchd becomes available again, but the streaming status RPC that is tied to window activation in the homescreen does not reconnect, and there seem to be some things that need to be resolved with respect to Qt object connection expiry to do so. If the Qt demos continue to be used in a significant fashion, this may be worth picking up.

2022-07-04Add VIS vehicle signal supportScott Murray4-0/+557
Add vehicle-signals library that exposes configuration and interface objects to use Vehicle Information Service (VIS) signals from a VIS server such as KUKSA.val. In this initial version Qt signals to expose some of the low level VIS errors to clients have not been implemented, as it is not immediately obvious how they could be leveraged in the AGL demo usecases. If the Qt demos continue to be used for past the Needlefish release this may warrant revisiting.
