Refactored binary serialization and cloning to use pool-backed byte[]-output overloads of AcBinarySerializer, reducing allocations and improving performance. Updated CloneTo and CopyTo to use explicit runtime types. SignalParams now emits a Null marker for nulls. Updated SignalRSerializationHelper to use lighter overloads. Added DebugLogArgument for deserialization debug logging. Improved comments and code clarity.
- 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.
Refactor SignalR protocol type resolution logic
Removed SignalParams.SignalDataType and migrated type resolution to protocol headers using new WriteHeader/ReadHeader extensibility hooks. AyCodeBinaryHubProtocol now writes and reads the concrete data argument type in the message header, enabling correct deserialization of object-typed arguments. Updated AcBinaryHubProtocol to support header context and made relevant helpers protected. Cleaned up legacy SignalDataType logic and improved documentation.
Implements a high-performance raw byte[] protocol path for SignalR DataSource GetAll/LoadDataSource, using a new IsRawBytesData flag in SignalParams. When enabled, the server pre-serializes response data and sends it as a byte array, which the protocol passes through without further (de)serialization. The client receives the raw bytes and deserializes as needed, avoiding double serialization/deserialization and improving performance for large payloads.
Adds SerializerType selection to DataSource, propagates SignalParams through hub and protocol layers, and updates client/server/test code to support the new path. Also includes diagnostics flags for binary serialization debugging and fixes for multi-segment buffer handling.
Major overhaul for SignalR response pipeline:
- All deserialization now uses byte[] (offset/length) for zero-copy, allocation-free operation; all span/memory overloads removed.
- SignalR protocol sends (signalParams, object) directly; SignalData envelope and related logic removed.
- Server sets SignalParams.SignalDataType so protocol deserializes to the correct runtime type on the client.
- SignalResponseDataMessage now only used for client request/response tracking and stream path; RawResponseData holds the actual object.
- All extension methods, helpers, and infrastructure updated to use new byte[]-based APIs.
- AcSignalRDataSource and all test/benchmark code updated for new object flow.
- Removes all diagnostics, logging, and error handling related to binary envelopes.
- Enables true zero-copy, type-safe, allocation-free SignalR response handling.
Major protocol/API change: replace SignalReceiveParams with SignalParams everywhere. SignalParams now carries packed method parameters as a single byte[] and provides SetParameterValues/GetParameterValues for type-safe packing/unpacking. All hub/client interfaces, method signatures, and dispatch logic updated. Legacy parameter serialization helpers removed; all parameter logic is encapsulated in SignalParams. Documentation and tests updated to reflect new wire format and flow. This unifies parameter handling, clarifies the protocol, and enables robust, extensible type-guided serialization. Breaking change.
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.
Major protocol update: OnReceiveMessage now takes metadata (SignalReceiveParams) and payload (byte[]) as separate hub arguments, not a single envelope. Metadata is AcBinary-serialized; payload uses protocol fast-path. Updated all client/server code, interfaces, and docs. Added ISignalParams and SignalReceiveParams types. Improved AcBinaryHubProtocol diagnostics and made byte[] fast-path more robust. This enables clearer, more debuggable, and future-proof SignalR binary messaging.
