Refactor: replace PipeReaderBinaryInput with SegmentBufferReader
- Remove PipeReaderBinaryInput and all related code.
- Add SegmentBufferReader and SegmentBufferReaderInput for efficient, thread-safe chunked streaming deserialization.
- Update AcBinaryDeserializer and AcBinaryHubProtocol to use the new buffer for async segment protocol, improving state management and background deserialization.
- Enhance chunked protocol handling: skip re-presented chunk start frames, track consumed chunk frame bytes, and improve logging.
- Update test infrastructure to support async segment protocol and add AsyncSegmentPipeTransportWriter for realistic testing.
- Update settings.local.json to reflect new build/test commands and remove obsolete files.
- Improves performance, reliability, and testability of chunked SignalR streaming.
Add a production-faithful test harness for SignalR binary protocol, introducing SlabTransportWriter to simulate Kestrel's slab allocator and always force the BufferWriterOutput owned-buffer path. Add large-payload round-trip tests (including non-ASCII cases) to catch position drift and data corruption bugs. Enhance protocol tests to validate multi-segment output and byte-for-byte correctness. All protocol round-trips now exercise the multi-segment, non-array-backed buffer path.
TestMultiSegmentProtocol now uses a custom MemoryPool to simulate Kestrel's slab allocator with 256-byte segments for both writing and reading. This replaces manual multi-segment sequence creation with a real Pipe backed by SlabSimulatingPool, ensuring more realistic segment boundaries and offsets. Old helpers were removed, and comments updated to clarify the improved simulation of production SignalR/Kestrel pipe behavior.
Moved BenchmarkTestDataProvider and TestDataSet to AyCode.Core.Tests.TestModels with public accessibility. Refactored dataset creation methods to accept a resetId parameter, allowing control over TestDataFactory ID resets. Improved code structure, formatting, and documentation for maintainability. The provider is now more flexible and easier to use in tests.
Introduce diagnostic and test infrastructure for SignalR binary protocol serialization/deserialization, including:
- ProtocolRoundTripDiagnosticTest for isolated protocol byte inspection
- TestMultiSegmentProtocol to exercise multi-segment buffer parsing
- TestInvocationBinder for correct parameter type binding
- Updates to TestableSignalRClient2 and TestableSignalRHub2 to route all messages through protocol round-trip
- Enhanced SendMessageToClient to simulate real SignalR transport
- Clarified SequenceBinaryInput segment handling logic
- Made TryParseMessage virtual in AcBinaryHubProtocol for testability
These changes improve test coverage for cross-boundary and multi-segment scenarios in SignalR message handling.
