- Refactored AcBinaryDeserializer string marker dispatch: hot path now handles all non-interning markers in a single inlinable method, cold path only for interning markers; improved safety and comments.
- Updated SGen codegen to only emit cold-path for interning-enabled types.
- Added debug guard for corrupted wire in ReadStringBig.
- Rewrote JitDisassemblyBenchmark as a direct JIT-disasm harness (outside BDN); updated Program.cs to use it for --jitasm.
- Benchmarks now pin charset to Latin1Short for cross-process consistency.
- Added new Bash commands for diff, JIT disasm, and diagnostics in settings.local.json.
Added WithProcessStabilization to pin CPU affinity and raise process priority for all BDN entry points, matching Console runner stabilization. Benchmark results are now ordered by Engine then RtPerOp for stable, diff-friendly output. Report headers clarify when BDN manages run parameters. Enhanced comments for clarity; no changes to benchmark logic.
- Introduce BDN-based runner (AcBinaryVsMemPackBenchmark) mirroring Console's FastestByte scenario; add BdnSummaryAdapter for unified result translation.
- Standardize output: both runners emit .log/.LLM/.output triplets; BDN-native artifacts go under Benchmark/BDN/.
- Simplify CLI: replace granular switches with --serializers; update help and usage.
- Remove legacy benchmark classes; focus on scenario-based approach.
- Rewrite README.md for both AyCode.Benchmark and Console to document dual-runner architecture, output conventions, and dependencies.
- Rotate BINARY_TODO.md; archive closed entries to BINARY_TODO_2026_04.md and BINARY_TODO_2026_05.md.
- Add BINARY_SGEN_OPTIMIZATION.md for SGen per-property emit optimization notes.
- Update comments and docstrings for clarity and maintainability; clarify BenchmarkResult iteration semantics for BDN rows.
Refactor tests to use _All_True model types throughout
Replaced all usages of legacy test model types (e.g., TestOrder, TestOrderItem, SharedTag, etc.) with new, feature-complete _All_True variants across SignalR test infrastructure, data sources, and service handlers. Updated all generic constraints, method signatures, and test data to use the new types. Added SharedTestBaseModels.cs and SharedTestOrderModels.cs to define abstract bases and concrete _All_True models with full serialization attributes. This enables more thorough and realistic serialization/deserialization testing and future extensibility.
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.
Introduce JitDisassemblyBenchmark for analyzing JIT-generated x64 assembly of AcBinarySerializer hot paths, accessible via --jitasm. Refactor string interning logic to support per-property and string collection interning, adding IsStringCollectionProperty and ScanStringCollection. Update ScanPass and WriteString for finer-grained control. Remove DEBUG-only CurrentPropertyPath in favor of a more robust property tracking approach. Update usage instructions and clean up related code.
- Refactor all serializer options to use properties returning new instances (no shared mutable state); update all usages accordingly
- Extract AcSerializerOptions, BinaryTypeCode, and BinaryPropertyFilterContext to dedicated files for clarity and reuse
- Add DEBUG-only string interning analysis/reporting tools to AcBinarySerializer
- Improve AcBinarySerializer string property serialization with direct typed getter and SIMD-optimized ASCII path
- Increase benchmark/test warmup iterations and add JIT warmup delays for more reliable performance measurements
- Remove redundant usings and update documentation/comments throughout
- No breaking API changes, but static readonly options fields are now properties
- 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.
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.
