Loretta b1cdf80fad Fix SignalR binary protocol: VarUInt framing & type-safe ser 
- Add type-explicit ToBinary/SerializeToBinary overloads to preserve runtime type info for object? serialization, fixing deserialization bugs.
- Refactor VarUInt encoding/decoding to a prefix-tiered scheme (1–5 bytes), replacing LEB128 and preventing buffer overrun/corruption.
- Update all SignalR and serialization call sites to use new overloads.
- Sync SignalR binary protocol VarUInt decoding logic; fix test regressions.
- Add SIGNALR_BINARY_PROTOCOL_VARUINT.md with new wire-format spec and rationale.
- Add debug logging for argument serialization.
- Update .gitignore to not ignore itself.
- Resolves 65 KB value cap and missing in-band abort marker; requires both sender/receiver to use new framing for full compatibility.

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/README.md. Binary protocol: For wire format, zero-copy pipeline, and three-path read logic see AyCode.Services/docs/SIGNALR_BINARY_PROTOCOL/README.md. Known issues: AyCode.Services/docs/SIGNALR/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.cs — ISignalParams 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/README.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.
