Added support for optional/default parameters in SignalR method invocation. The hub now fills in missing arguments with default values when not provided, and throws if required parameters are missing. Added comprehensive tests for default parameter handling, a new handler method for testing, and a tag constant. Also improved code style with C# pattern matching and made UseStringCaching immutable.
Major overhaul of binary serializer/deserializer tests: split and expand test coverage for primitives, objects, navigation, generics, circular refs, and edge cases. Fix critical bugs in property skipping, string interning, type mismatch diagnostics, nullable assignment, and VarInt decoding. Add WASM-optimized deserialization options with string caching. Switch SignalR compression from Brotli to Gzip and introduce GzipHelper. Add comprehensive StockTaking test models and real-world bug reproductions. Improve diagnostics, test discovery, and add benchmark/utility scripts.
Major refactor: all SignalR responses now use a single unified `SignalResponseDataMessage` type with binary payloads. JSON responses are Brotli-compressed for efficiency. Removed legacy JSON/Binary response types and MessagePack server-to-client serialization. Updated all serialization extensions for zero-allocation binary ops. Refactored client/server/data source/test code to use new message and serialization model. Improved deserialization robustness for primitives. Modernized and streamlined test suite.
- Fix: Ensure property names and skipped strings are interned during binary deserialization, preventing interned string index mismatches.
- Add: Extensive regression tests for string interning edge cases, including property mismatch (server has more properties than client), deeply nested objects, repeated/unique strings, and empty/null handling.
- Add: New test DTOs and infrastructure for property mismatch scenarios.
- Update: SignalR test helpers and services to support both JSON and Binary serialization in all tests.
- Improve: SignalRRequestModelPool now initializes models on Get().
- These changes address production bugs and ensure robust, consistent string interning and property skipping in AcBinarySerializer.
Add regression tests for string-stored DateTime values in GenericAttribute-like collections, ensuring exact value preservation in Binary serialization. Fix AcBinaryDeserializer to only intern strings >= 4 chars, matching serializer logic and preventing intern table index mismatches. Refactor SignalR tests to run under both JSON and Binary modes, and add comprehensive tests for edge cases and production bug scenarios. Clean up test code and comments for clarity.
Major overhaul of JSON serialization/deserialization:
- Added AcJsonDeserializationException for clearer error reporting.
- Robust JSON validation, type checking, and double-serialization detection.
- Fast-path primitive (de)serialization for all common .NET types.
- Direct support for Dictionary<TKey, TValue> and improved collection handling.
- Enhanced $id/$ref reference resolution and in-place merging.
- Optimized property metadata caching and filtering.
- Comprehensive error handling with detailed messages.
- Extensive new tests for primitives, collections, references, and error cases.
- Benchmarks for serialization, deserialization, and merge scenarios.
SignalR infrastructure improvements:
- Refactored AcSignalRClientBase/AcWebSignalRHubBase for testability (virtual methods, test constructors).
- Added SignalRRequestModelPool for efficient request/response tracking.
- Improved parameter deserialization and IdMessage handling.
- New tags (PingTag, EchoTag) for SignalR messaging.
New test and benchmark infrastructure for SignalR:
- Shared test models and data factories for DTOs, primitives, and complex graphs.
- In-memory, dependency-free SignalR client/hub for round-trip testing.
- Exhaustive test suites for message processing, method invocation, and edge cases (including prior production bugs with Task<T>).
- Benchmarks for SignalR serialization, deserialization, and round-trip performance.
Other changes:
- Improved TaskHelper.WaitTo/WaitToAsync with more accurate polling and cancellation support.
- ExtensionMethods.InvokeMethod now properly unwraps Task/ValueTask results.
- General code cleanup, improved comments, and removal of obsolete code.
- Project references updated for shared test/benchmark infrastructure.
These changes deliver a robust, high-performance, and fully tested JSON/SignalR (de)serialization system, ready for production and advanced testing scenarios.
