- 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.
Major overhaul of JSON serialization/deserialization:
- Introduce AcJsonSerializerOptions for reference handling and max depth
- Centralize type checks, primitive/collection logic in JsonUtilities
- Add depth limiting to serializer/deserializer (MaxDepth support)
- Make $id/$ref reference handling optional via options
- Unify and simplify public API (ToJson, JsonTo, CloneTo, CopyTo, etc.)
- Improve primitive, enum, and collection handling and caching
- Refactor contract resolver and merge logic to use new utilities
- Remove redundant code, centralize string escaping/unescaping
- Update all tests and benchmarks to use new API and options
- Fix minor bugs and improve error handling and validation
This modernizes and unifies the JSON infrastructure for better performance, flexibility, and maintainability.
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.
