- 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 AcBinaryHubProtocol for thread safety
- Removed shared _currentHeaderContext; header context is now passed as a parameter through Parse* and ReadArguments/ReadSingleArgument methods, and stored per-binder for chunked messages.
- Updated AyCodeBinaryHubProtocol to use the new header context flow for type resolution and argument deserialization.
- Added concurrency tests to verify protocol instance safety under multi-threaded use and prevent state corruption or type resolution races.
- Improved documentation and comments to clarify the stateless, concurrency-safe design.
Refactor SignalR protocol registration; add DI options
- Added AcSignalRServerProtocolExtensions and AcSignalRProtocolExtensions for idiomatic AddAcBinaryProtocol registration (server/client), using a shared BuildProtocol factory for DI/IOptions/inline config.
- Introduced AcHubConnectionOptions and AcSignalRConnectionExtensions for configuration-driven client setup.
- Refactored AcSignalRClientBase to require a preconfigured IHubConnectionBuilder, moving all connection/protocol config out of the base class.
- Removed legacy protocol constructors; all protocol instantiation is now options-based.
- Enforced WASM + AsyncSegment guard in AcBinaryHubProtocolOptions.Validate.
- Updated SIGNALR_BINARY_PROTOCOL.md and GLOSSARY.md for new DI/config patterns.
- Minor: updated settings.local.json with new DLL/plugin inspection commands.
- Added AcBinaryHubProtocolOptions for unified protocol configuration (serializer, mode, buffer size, flush strategy, timeout, name, logger) with validation and DI support.
- Refactored AcBinaryHubProtocol and AyCodeBinaryHubProtocol to use options object; legacy constructors now delegate to options-based API.
- Added per-chunk flush timeout to AsyncPipeWriterOutput and AcBinarySerializer; throws TimeoutException on slow consumers.
- Improved XML docs and comments for pipeline/backpressure/timeout clarity.
- Updated SIGNALR_BINARY_PROTOCOL.md to document new options and AsyncSegment platform rules.
- Simplified logging with null-conditional operators
- Temporarily disabled WASM AsyncSegment guard for testing
- Unified argument deserialization via GetArgBytes for zero-copy and pooled buffer support
- Removed DeserializeFromSequence in favor of new approach
- Applied improvements to AyCodeBinaryHubProtocol
- Updated comments and performed minor code cleanup
Refactor AyCodeBinaryHubProtocol header logic
Refactored the per-message header to use a DataFlags enum, encoding data argument properties in a single byte for more expressive client handling. Introduced HeaderContext to encapsulate header state. Updated WriteHeader and ReadHeader to use the new format, and refactored ReadSingleArgument to support fast-paths for byte[], ConsumerDeserialize, and header-supplied types. Removed obsolete _currentSignalParams logic and improved documentation throughout.
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.
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.
Implement self-describing chunked protocol ([201][UINT16][data], [202] end) for AsyncSegment mode, enabling true zero-copy, pipeline-parallel serialization/deserialization of large arguments in SignalR.
- AsyncPipeWriterOutput now reserves a 3-byte header per chunk and supports two backpressure modes.
- AcBinaryHubProtocol routes streamable arguments through WriteMessageChunked, with chunk accumulation and background deserialization on the receiver.
- Logging now uses ILogger; documentation and wire format details updated.
- Consumer code updated to use new mode and diagnostics.
- Improves throughput, memory usage, and maintainability for large payloads.
Refactored binary protocol to support three explicit serialization/transport strategies via BinaryProtocolMode: Bytes (byte[]), Segment (zerocopy PipeWriter), and AsyncSegment (async PipeWriter with pipeline parallelism). Updated AcBinaryHubProtocol and AyCodeBinaryHubProtocol to select serialization/deserialization paths based on mode. Improved documentation and XML comments to describe each mode's behavior and performance. DI registration now explicitly selects AsyncSegment mode for AyCodeBinaryHubProtocol. Default remains Bytes mode. These changes clarify protocol mechanics and enable better performance tuning.
Implements segment-level streaming for SignalR binary protocol via new AsyncPipeWriterOutput and PipeReaderBinaryInput types, enabling chunked serialization/deserialization directly over PipeWriter/PipeReader. Adds BinaryProtocolMode enum to select between standard and streaming modes. Updates protocol classes and documentation. Lays groundwork for future async streaming support.
Refactored AcBinaryHubProtocol and AyCodeBinaryHubProtocol to remove the VarUInt length prefix for raw byte[] arguments. Now, the protocol writes a tag (0x44) followed directly by the raw bytes, with argLength implying the payload size. Updated read logic to match: on detecting the tag, the code skips it and returns the remaining bytes as the payload. Updated documentation to clarify the new fast-path, protocol roles, and AcBinary detection. Set BufferWriterChunkSize to 4096 for SignalR in the base protocol for better alignment with Kestrel. Marked the related issue as resolved.
- Move SignalParams-aware deserialization logic from AcBinaryHubProtocol to new AyCodeBinaryHubProtocol, enabling project-specific customization.
- Make key deserialization and helper methods in AcBinaryHubProtocol protected and virtual for easier extension.
- Improve byte[] handling to distinguish between AcBinary-serialized and raw data.
- Remove diagnostic serialization verification from the base protocol.
- Update DI registration to use AyCodeBinaryHubProtocol with configurable options.
- Adjust client code to support object-based response data and raw byte handling.
- Comment out SignalResponseDataMessage diagnostic logger in Program.cs.
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 refactor: all byte[] payloads in SignalR hub/client interfaces, plumbing, and DTOs are now wrapped in SignalData, a disposable, ArrayPool-backed type with Span access. Introduces AyCodeBinaryHubProtocol (derived from AcBinaryHubProtocol) to rent pooled buffers for SignalData on receive. All message signatures, diagnostics, and serialization logic updated. Documentation and tests revised to reflect SignalData usage. Enables zero-copy, low-GC, high-performance binary messaging for large payloads.
