Refactored AcBinarySourceGenerator to use RefAwareEmitPredicate for all ref-handling switch decisions, ensuring child property ref-marker logic is based solely on child compile-time flags. Fixed deserialization drift when parent disables ref-handling but child enables it. Added regression tests and new test models to verify correct round-trip behavior for duplicate child references in collections and dictionaries. Improved XML docs and updated conventions for summary tags. Added SGen string round-trip tests for medium UTF-8/ASCII cases.
Major refactor: all benchmark engine implementations, enums, and helpers moved from Console project to AyCode.Core.Benchmarks.Workloads.Scenarios for unified cross-runner use. BenchmarkResult and reporting logic moved to AyCode.Core.Benchmarks.Reporting. Attribute-flag aggregation centralized in BenchmarkOptions. Updated all usages, project references, and SGen codegen for ref-handling. Prepares codebase for shared reporting and future extensibility.
- Moved interned string decode logic to BinaryDeserializationContext instance methods, reducing duplication and unifying SGen, runtime, and cross-type paths.
- Updated SGen-emitted code and TypeReaderTable to use new context methods.
- Added performance TODO (ACCORE-BIN-T-K9M3) documenting rationale and acceptance.
- Clarified AcBinarySerializableAttribute XML docs.
- Added repo-scoped nuget.config for deterministic restore.
- Updated settings.local.json with new Bash/dev commands.
- Minor code and comment cleanups for clarity.
Add per-type EnablePolymorphDetectFeature flag
Replaces the global UsePolymorphType constant with a per-type EnablePolymorphDetectFeature flag on AcBinarySerializableAttribute. The source generator now emits or omits polymorphic type info for System.Object properties based on this flag, defaulting to enabled. Updates diagnostics, documentation, and SerializableClassInfo to support this feature, clarifying the risks of disabling it and improving attribute XML docs for all feature flags.
Rename ShallowCopy to FlatCopy, add polymorph support
- Renamed all "ShallowCopy" serializer presets and references to "FlatCopy" for clarity and consistency.
- Expanded documentation to clarify flat serialization use cases, especially for delta-update and partial-write scenarios.
- Added EnablePolymorphDetectFeature to AcBinarySerializableAttribute and updated all constructor overloads.
- Set UsePolymorphType = true in AcBinarySourceGenerator to enable polymorphic type support by default.
- Updated all [AcBinarySerializable(...)] usages to include new feature flags, explicitly disabling property filter and polymorph detection for affected types.
- Improved comments and documentation for maintainability.
Enable per-type property filter opt-out in AcBinary
Adds EnablePropertyFilterFeature to AcBinarySerializableAttribute, allowing types to opt out of property filter codegen and runtime checks. Updates source generator, metadata, and runtime logic to honor this flag. Removes UsePropertyFilter constant; emission is now attribute-driven. Also optimizes string serialization for non-ASCII cases and refactors deserializer byte reads for trusted single-segment fast paths. Backward compatible: property filter remains enabled by default.
- Add BINARY_FORMAT.md: full AcBinary wire format spec (markers, encoding, options, protocol, interactions)
- Reference BINARY_FORMAT.md from GLOSSARY.md, Binaries/README.md, and Serializers/Binaries/README.md; add new glossary terms
- Clarify and expand config options tables to match new doc
- Add/clarify LLM maintenance rules: always sync .md files with code, auto-fix discrepancies
- Update root README.md: AyCode.Core targets .NET 9, not 10; stress doc/code sync
- Add code reuse and doc sync conventions to copilot-instructions.md and CONVENTIONS.md
- Add docs/ folder and BINARY_FORMAT.md to solution as Solution Items
- Minor clarifications and cross-links in ARCHITECTURE.md and other docs
Updated test and benchmark project dependencies to latest versions (BenchmarkDotNet, coverlet.collector, MSTest, etc.). Reformatted source generator project references for consistency. Commented out most AcBinary benchmark variants in Program.cs, leaving only FastMode+Default enabled. Significantly expanded README with detailed architecture, file descriptions, and configuration for each serializer subfolder. Added LLM maintenance notes to ensure documentation stays in sync with code changes.
Implements a fully source-generated scan pass for duplicate/reference tracking in SGen binary serialization. The generator now emits ScanObject and ScanForDuplicates methods for each writer, handling null/depth checks, slot-based ref tracking (by Id or object hash), and recursive property scanning (strings, complex types, collections). String interning and reference tracking are feature-flagged via attributes. The runtime scan path now delegates to generated code when available, eliminating reflection and delegate overhead. Adds slot-based IdentityMap arrays to the serialization context for efficient duplicate detection. Also updates metadata, attributes, and test stubs to support these features.
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.
