Loretta cdd54d3196 Refactor SignalR param serialization to pure binary format 
Replaces legacy JSON-in-Binary parameter envelopes with a length-prefixed, per-parameter binary format for all client→server calls. Introduces SerializeParametersToBinary and DeserializeParametersFromBinary for type-safe, zero-copy parameter handling. Marks IdMessage, SignalPostJsonDataMessage, and related wrappers as obsolete. Updates all client CRUD/messaging helpers and server-side dispatch to use object[] binary serialization. Adds DataSerializerType to SignalReceiveParams for response format indication. Updates tests and documentation to reflect new protocol. BREAKING CHANGE: not compatible with previous JSON-in-Binary clients/servers.

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 dual BWO pattern see AyCode.Services/docs/SIGNALR_BINARY_PROTOCOL.md.

Key Files

Protocol

  • AcBinaryHubProtocol.cs — Custom IHubProtocol replacing JSON+Base64 with AcBinarySerializer. Handles all 9 SignalR message types (Invocation, StreamItem, Completion, Ping, Close, etc.). Uses BufferWriterBinaryOutput standalone mode for zero-copy writes to the SignalR pipe. byte[] fast-path bypasses the serializer entirely. Inner SpanReader ref struct for zero-alloc parsing.

Client

  • AcSignalRClientBase.cs — Abstract SignalR client managing HubConnection, request/response tracking via pooled SignalRRequestModel. Methods: SendMessageToServerAsync<TResponse>(), CRUD helpers (Post, Get, GetAll, GetAllInto). Configurable timeouts.
  • IAcSignalRHubClient.cs — Client interface + SignalResponseDataMessage (sealed, supports JSON/Binary with GZip, caching, diagnostics).
  • IAcSignalRHubBase.cs — Base hub interface: OnReceiveMessage(int messageTag, int? requestId, SignalReceiveParams receiveParams, byte[] data).
  • ISignalParams.cs — ISignalParams base interface + SignalReceiveParams (Status). Metadata travels as separate hub argument (AcBinary serialized), payload byte[] uses protocol fast-path (zero-copy).

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, CreateResponseData().
  • SignalRRequestModel.cs — Poolable (IResettable) request tracking model with ObjectPool for reuse.
