Loretta e73e1b6364 Optimize Pipe sync handling, logging, and chunked protocol
Refactor synchronous PipeReader/PipeWriter usage to avoid Task allocations via fast-path helpers. Add detailed debug/trace logging for chunked message flows and deserialization. Track active reads to prevent protocol errors. Refactor FindStreamedArgSlot and introduce ResolveStreamedArgType for dynamic streamed arg type resolution, with AyCodeBinaryHubProtocol override. Minor code cleanups and improved logging context throughout. Improves performance, correctness, and debuggability.

SignalRs

Custom binary SignalR protocol, client infrastructure, message tagging, and serialization helpers.

Architecture: For full dispatch flow, tag system, and tech debt documentation see AyCode.Services/docs/SIGNALR.md. Binary protocol: For wire format, zero-copy pipeline, and three-path read logic see AyCode.Services/docs/SIGNALR_BINARY_PROTOCOL.md. Known issues: AyCode.Services/docs/SIGNALR_ISSUES.md

Key Files

Protocol

  • AcBinaryHubProtocol.cs — Unsealed base IHubProtocol replacing JSON+Base64 with AcBinarySerializer. Handles all 9 SignalR message types. Write: BufferWriterBinaryOutput standalone + AcBinarySerializer.Serialize(value, output) zero-copy to pipe. byte[] fast-path writes tag+VarUInt+bytes via BWO. Read: SequenceReader<byte> from pipe's ReadOnlySequence. Three-path ReadSingleArgument: byte[] fast-path (0x44 tag), IsRawBytesData (raw byte[]), typed deser via SignalDataType. _currentSignalParams captures arg[2] for type-aware arg[3] deserialization.
  • AyCodeBinaryHubProtocol.cs — Derived protocol (currently empty). Exists for registration and future project-specific hooks. Register this instead of AcBinaryHubProtocol.

Client

  • AcSignalRClientBase.cs — Abstract SignalR client managing HubConnection, request/response tracking via pooled SignalRRequestModel. SendCoreAsync builds SignalParams (with IsRawBytesData when T == byte[]). CRUD helpers (Post, Get, GetAll, GetAllInto). Configurable timeouts.
  • IAcSignalRHubClient.cs — Client interface + SignalResponseDataMessage (sealed, RawResponseData is object? — typed object or byte[], GetResponseData<T>() direct cast). Legacy message types (IdMessage, SignalPostJsonDataMessage) marked [Obsolete].
  • IAcSignalRHubBase.cs — Base hub interface: OnReceiveMessage(int messageTag, int? requestId, SignalParams signalParams, object data).
  • ISignalParams.csISignalParams base interface + SignalParams (Status, DataSerializerType, Parameters byte[]?, SignalDataType string?, IsRawBytesData bool). Metadata travels as separate hub argument (AcBinary serialized). Parameters and data are independent — both nullable in any direction.

Message Tagging

  • SignalMessageTagAttribute.cs — Three attributes: TagAttribute (base, int messageTag), SignalRAttribute (server method routing + client notification), SignalRSendToClientAttribute (client-side receive).
  • AcSignalRTags.cs — Static constants: None, PingTag, EchoTag.
  • SignalRCrudTags.cs — Sealed class bundling 5 independent CRUD tag integers. GetMessageTagByTrackingState() maps TrackingState -> tag. See AyCode.Services.Server/docs/SIGNALR_DATASOURCE.md.
  • SendToClientType.cs — Enum: None, Others, Caller, All.

Serialization & Pooling

  • SignalRSerializationHelper.cs — Static helpers: SerializeToBinary(), DeserializeFromBinary(), compressed JSON variants.
  • SignalRRequestModel.cs — Poolable (IResettable) request tracking model with ObjectPool for reuse.
