Problem/Opportunity

Create a framework to implement AIDL Versioning for RDK-E HAL.

1. Update API: Validate and create a snapshot of the current APIs
2. Freeze API: Freeze the snapshot of the current API to the next version
3. Generate Sources: Generate sources which has implementation for getInterfaceVersion()

Proposed Solution

1. Interfaces will be defined in YAML or JSON
2. A framework will be designed based on Python, which will read these definitions to carry out the required operation.
3. Operations: update_api, freeze_api, generate_sources, generate interface library dependency tree
4. CMake configuration will be written to generate libraries as the main project requires.

Acceptance Criteria (Optional)

AC1 - AIDL interface version management for RDK-E
The AIDL build system shall support snapshotting an AIDL interface version as a new version and perform backwards compatibility checks.

AC2 - Interface Version Checking through Binder Support
An application shall be able to call getInterfaceVersion() on a binder service to retrieve its AIDL version.

AC3 - Provide Documentation for AIDL Versioning
Documentation shall be created to provide step-by-step instructions on how to create AIDL interface version snapshots in an RDK environment.
