Summary

This pull request includes the following changes:

  • Documentation: Added detailed module- and class-level docstrings in RPC.py including parameter descriptions, usage examples, and public interface definitions. Updated code comments for better clarity.
  • Refactoring: Improved lifecycle management in RPCServer and introduced enhancements to RPCSignal, such as weak reference handling and improved callable validation. Centralized traceback logging and improved logging consistency.
  • Testing: Implemented unit tests for RPC functionalities, DeviceRegistry, and failure scenarios. Tests simulate real-world usage with mock implementations and capture edge cases related to server lifecycle and reconnection.

- Introduced `test/test_RPC_registry.py` with comprehensive unit tests covering:
  - Device registration, lifecycle, and overwrite protection in `DeviceRegistry`.
  - Core `RPC` functionalities, including method calls, property handling, signal propagation, and unknown method handling.
  - Robustness tests for handling server restarts, client-server reconnections, and registry crashes.
- Added mock server and client implementations (`TestDevice` and `TestClientProxy`) to simulate `RPCServer` and `RPCClient` behaviors for testing.
- Designed failure scenarios for completeness, highlighting areas needing improvement in `RPCServer` lifecycle and client timeout handling.
- Added detailed class docstrings to `RPCSignal` and `RPCProperty` with usage examples and parameter explanations.
- Introduced weak reference handling in `RPCSignal`, ensuring proper garbage collection and preventing memory leaks.
- Improved signal emission behavior by verifying callable validity before invocation.
- Enhanced type annotations and validation in `RPCSignal` to support modern Python type hints.
- Refactored `RPCServer.serve_forever` to delegate event handling to dedicated methods for better readability and maintainability.
- Consolidated repeated traceback printing into a new static method `_print_traceback_from_remote`.
- Replaced several warning logs with error logs to signify critical issues more clearly.
- Updated `RPCServer` to raise exceptions during serious errors (e.g., unreachable proxy) instead of returning warnings.
- Added comprehensive module-level docstrings in `RPC.py` to describe the RPC framework, its components, and usage.
- Introduced detailed class docstrings for `RPCClient`, `RPCServer`, `RPCSignalReceiver`, `RPCProperty`, `RPCSignal`, and `NoResult`.
- Improved method docstrings across multiple classes to include parameter descriptions, return types, and raised exceptions.
- Added `__all__` in `RPC.py` to explicitly define public exports for the module.
- Enhanced existing code by clarifying lifecycle behaviors, event handling, and error scenarios in various methods.
