From 2f99b4e3b7192bba17e1179d1646efdaecb49ec6 Mon Sep 17 00:00:00 2001 From: Loretta Date: Tue, 10 Mar 2026 17:32:00 +0100 Subject: [PATCH] Refactor SGen: property/object marker bridges, FixObj support Major refactor of binary serialization codegen and runtime: - Added property writer bridge methods for markerless/metadata paths - Centralized object marker logic via new bridge methods - Simplified SGen output: single bridge call replaces branching - FixObj slot markers now supported in serialization/deserialization - Refactored collection/dictionary element serialization - Removed redundant WritePropertyMarkerless method - Improved tests: use BinaryTypeCode constants, FixObj parsing - Added InternalsVisibleTo for test project access - Annotated TestSimpleClass for SGen support Reduces generated code size, improves maintainability, and ensures correct handling of new binary format features. --- .../AcBinarySourceGenerator.cs | 398 ++++----------- .../AcBinarySerializerDiagnosticTests.cs | 137 +++--- .../AcBinarySerializerIIdReferenceTests.cs | 13 +- .../TestModels/AcSerializerModels.cs | 2 + AyCode.Core/AyCode.Core.csproj | 3 +- .../Binaries/AcBinaryDeserializer.cs | 22 +- ...arySerializationContext.PropertyWriters.cs | 457 ++++++++++++++++++ ...rySerializer.BinarySerializationContext.cs | 2 +- .../Binaries/AcBinarySerializer.cs | 219 ++------- 9 files changed, 690 insertions(+), 563 deletions(-) create mode 100644 AyCode.Core/Serializers/Binaries/AcBinarySerializer.BinarySerializationContext.PropertyWriters.cs diff --git a/AyCode.Core.Serializers.SourceGenerator/AcBinarySourceGenerator.cs b/AyCode.Core.Serializers.SourceGenerator/AcBinarySourceGenerator.cs index 57ab9ff..c7556c5 100644 --- a/AyCode.Core.Serializers.SourceGenerator/AcBinarySourceGenerator.cs +++ b/AyCode.Core.Serializers.SourceGenerator/AcBinarySourceGenerator.cs @@ -665,21 +665,9 @@ public class AcBinarySourceGenerator : IIncrementalGenerator if (IsMarkerless(p.TypeKind)) { if (!enableMetadata) - { - // Per-type metadata disabled — always markerless, no branch EmitMarkerless(sb, p.TypeKind, a, i); - } else - { - sb.AppendLine($"{i}if (context.UseMetadata)"); - sb.AppendLine($"{i}{{"); - EmitSkip(sb, p.TypeKind, a, p.TypeNameForTypeof, i + " "); - sb.AppendLine($"{i}}}"); - sb.AppendLine($"{i}else"); - sb.AppendLine($"{i}{{"); - EmitMarkerless(sb, p.TypeKind, a, i + " "); - sb.AppendLine($"{i}}}"); - } + EmitPropertyBridge(sb, p.TypeKind, a, i); return; } @@ -811,6 +799,38 @@ public class AcBinarySourceGenerator : IIncrementalGenerator } } + /// + /// Emits a single bridge method call for markerless property types with enableMetadata=true. + /// The bridge method on BinarySerializationContext handles both UseMetadata=true (markered+skip) + /// and UseMetadata=false (markerless) paths internally.
