- Replace UseReferenceHandling bool with ReferenceHandlingMode enum across all serializers and options
- Move AcBinary string interning to footer (no header shifting); remove bloom filter
- Overhaul benchmark console: multi-serializer, grouped/colorized results, CSV/log output, more test data
- Set UseMetadata = false by default (header property names unused)
- Update all context Reset/Pool logic for new options signature
- Update AcJson/Toon serializers for new reference handling
- Update tests and usages for new enum-based options
- Add Newtonsoft.Json to benchmark dependencies
- Misc: code cleanups, improved comments, clarify logic
Adds robust IId<T>-based reference deduplication to both serialization and deserialization. Objects with the same type and Id are now treated as the same reference, reducing output size and ensuring correct reference identity in complex graphs.
Key changes:
- TypeMetadataBase: Adds IdAccessorType, typed Id getters, and precomputed property arrays for zero-boxing and fast access.
- AcSerializerCommon: Introduces IIdReferenceTracker for efficient (Type, Id) → object mapping.
- SerializationReferenceTracker: Now supports both ReferenceEquals and IId-based tracking for scanning and writing.
- AcBinarySerializer: Reference scan uses IId-aware deduplication, skipping types that don't need tracking.
- AcBinaryDeserializer: Adds per-context IId caches to ensure reference identity on deserialization.
- PropertyAccessorBase: Adds IsComplexType for fast scan decisions.
- Populate/Chain: Integrated with new IId cache for correct deduplication.
- Tests: Adds/updates tests for IId identity, cross-type safety, and diagnostics.
- Benchmarks: Adds WithRef/NoRef and AcJson vs System.Text.Json.
- Documentation: Includes detailed implementation plan and rationale.
No breaking changes for types that do not use IId. Zero-boxing for int/long/Guid Ids. Reference identity is now preserved for all IId objects.
Introduce Roslyn Source Generator for AcBinary serialization, generating optimized Serialize/Deserialize methods for types marked with [AcBinarySerializable]. Integrate generator as analyzer in core, tests, and benchmarks. Update metadata to detect generated serializers. Add benchmarks and integration tests to validate performance and correctness. Update project files and internals visibility for testing. Existing runtime serialization remains as fallback.
Introduce AcDynamicMethodRegistry<TAttribute> for efficient, static caching and lookup of SignalR methods by messageTag and type. Replace per-instance method lists with a high-performance registry, update all registration and invocation logic to use the new approach, and make method metadata caching type-based and immutable. Also expand Bash permissions in settings.local.json and rename ReadVarUIntFromBytes for consistency. This improves performance, maintainability, and code clarity for dynamic SignalR method invocation.
- Introduced AcJsonSerializer/AcJsonDeserializer in AyCode.Core.Serializers.Jsons, optimized for IId<T> reference and circular reference handling.
- Added AcJsonSerializerOptions/AcSerializerOptions for configurable reference handling and max depth.
- Implemented fast-path streaming (Utf8JsonReader/Writer) with fallback to DOM for reference scenarios.
- Added type metadata/property accessor caching for performance.
- Provided robust object/collection population with merge semantics for IId<T> collections.
- Added AcJsonDeserializationException for detailed error reporting.
- Implemented UnifiedMergeContractResolver for Newtonsoft.Json, supporting JsonNoMergeCollectionAttribute to control merge behavior.
- Added IdAwareCollectionMergeConverter<TItem, TId> for merging IId<T> collections by ID.
- Included helpers for ID extraction and semantic ID generation.
- Added DeepPopulateWithMerge extension for deep merging.
- Optimized with frozen dictionaries, pre-encoded property names, and context pooling.
- Ensured compatibility with both System.Text.Json and Newtonsoft.Json.
- Add property-level filtering via BinaryPropertyFilter delegate and context
- Improve string interning with new StringInternNew type code and promotion logic
- Optimize array and dictionary serialization for primitive types
- Expose strongly-typed property accessors for primitives and enums
- Add new benchmarks for serialization modes
- Refactor buffer pooling and cleanup code
- All new features are opt-in; maintains backward compatibility
- Add BSON (MongoDB.Bson) as a serialization format in benchmarks, enabling direct comparison with AcBinary, MessagePack, and JSON.
- Update all AcBinary benchmarks to use options without reference handling for fair comparison.
- Show BSON results and ratios in benchmark output and size comparisons.
- Refactor AcBinaryDeserializer to use a fixed-size array for type reader dispatch, improving lookup speed and reducing allocations.
- Add a concurrent cache for type conversion info to optimize enum and nullable conversions.
- Use a cached UTF8Encoding instance for string decoding.
- Use FrozenDictionary for property lookup in BinaryDeserializeTypeMetadata.
- Remove legacy WithRef code paths and clean up formatting and comments.
- Improve error handling and fallback logic for BSON serialization/deserialization.
Renamed the benchmark project from BenchmarkSuite1 to AyCode.Benchmark, updating the solution reference and moving all benchmark source files under the new project and namespace. No functional changes were made; this is a structural and naming reorganization for clarity and maintainability.
