Refactored AcBinarySerializer to write type property metadata inline
after the ObjectWithMetadata marker, eliminating the need for a
separate metadata footer section. Updated serialization, deserialization,
and diagnostic test logic to support the new inline metadata format.
Also updated settings.local.json to allow "Bash(git stash:*)" commands.
Introduce UseMetadata mode with FNV-1a property name hashing.
Write per-type property hashes to metadata footer for robust
property matching during deserialization. Remove legacy property
name table logic. Add ObjectWithMetadata marker and cachemap
logic for nested objects. Enable duplicate hash detection and
make UseMetadata default. Improves schema evolution support.
Update list factory cache and GetOrCreateListFactory to accept a capacity parameter, enabling preallocation of lists during deserialization. Adjust deserializer code to pass collection size where available, improving performance and memory usage. Also, pre-size dictionaries on creation and add Bash(find:*) to allowed commands in settings.local.json.
Major refactor: split AcToonSerializer.MetaSection.cs into focused modules for meta writing, type/enum definitions, navigation, foreign key, validation, descriptions, placeholders, topological sort, and attribute detection. Extend ToonDescriptionAttribute with BusinessRule, TypeRelation, and RelatedTypes for richer metadata. Add ToonTypeRelation constants. Annotate all DTOs with ToonDescription for type relationships. Refactor TypeMetadataBase for customizable ignore filters. Update tests and settings. Improves maintainability, extensibility, and metadata accuracy.
- Introduce AcNavigationPropertyInfo for unified, cached relationship metadata per property (primary key, navigation type, FK, other key, inverse, target type)
- Refactor relationship detection to use AcNavigationPropertyInfo, replacing ad-hoc logic and old RelationshipMetadata
- Add AcSerializerCommon.GetCSharpTypeName for consistent, C#-style type name formatting (handles primitives, generics, nullables, enums, collections)
- Use topological sort for @types output to ensure dependency order
- Improve enum handling: avoid redundant constraints, use new type name formatter for underlying types
- Output navigation, foreign-key, other-key, and inverse-property metadata consistently in meta section
- Enhance convention-based detection for inverse properties and "other key", including unidirectional/polymorphic support
- Add comprehensive test for navigation metadata completeness and demo test entities
- Add "source-code-language: C#" to meta section
- Misc: code cleanup, remove unused cache, improve property filtering
- Remove redundant constraints (nullable, numeric, boolean) from metadata; only explicit [Required] is documented.
- Exclude enum values from constraints; add "readonly" for readonly/init-only properties.
- Filter out primitives from documented types; only complex types and enums are included.
- Detect and document enum backing fields with "enum-type" constraint.
- Only output descriptions if explicitly provided; no fallback/inferred text.
- Add "not-mapped" constraint for [NotMapped]/[NotColumn] properties.
- Switch FruitBankHybrid.Shared.Tests.csproj to direct AyCode.Core project reference.
- Add both LinqToDB and DataAnnotations [Table] attributes to DTOs for ORM compatibility.
- Refined type metadata serialization: collections and dictionaries are now detected and described more accurately, avoiding generic type names (e.g., List`1) and redundant "object" element types.
- Added circular reference protection to type name generation to prevent stack overflows and duplicate type names.
- Updated AcToonSerializerOptions.Compact to use indentation for better readability.
- Introduced ToonTests with unit tests to ensure type metadata correctness, uniqueness, and clarity.
- Added AyCode.Core project to the solution and adjusted namespaces/usings for consistency.
Refactored object serialization to use fixed property order and a new PropertySkip marker for default/null values, removing property count and index overhead. Updated deserialization logic to handle skip markers and set defaults efficiently. Added WritePropertyOrSkip and SetPropertyToDefault methods for single-pass, boxing-free property handling. SkipObject now throws for new format. Updated BinaryTypeCode, .gitignore, and settings.local.json.
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.
- Enable deserialization and population from TSource to TDest with automatic or custom property mapping (by name or via PropertyMapper).
- Add PropertyMapperDelegate and options for custom mapping logic.
- Implement PropertyMappingCache and BinaryIndexMappingCache for efficient, thread-safe mapping reuse.
- Ensure stable, inheritance-aware property ordering in TypeMetadataBase for reliable cross-type mapping.
- Add CrossTypeDeserializerBase utility for shared cross-type logic.
- Add AcBinaryDeserializer.CrossType with new Deserialize<TSource, TDest> and Populate<TSource, TDest> overloads.
- Update settings.local.json to allow additional Bash commands for development.
- Improve documentation and add missing using directives.
- Introduced a high-performance, reusable "chain" API for JSON deserialization and object population, enabling parsed JSON to be reused for multiple deserializations without reparsing. Exposed via new extension methods and interfaces (`IDeserializeChain<T>`, `IPopulateChain`).
- Added comprehensive infrastructure for serializing and deserializing .NET Expression trees to a universal DTO (`AcExpressionNode`), with full round-trip support and robust handling of constants, closures, and queryable expressions.
- Centralized all property accessor and expression utilities in `AcSerializerCommon` to avoid duplication and improve maintainability.
- Enhanced both JSON and binary serializers to support Expression and IQueryable types, with automatic conversion to/from `AcExpressionNode`.
- Refactored type metadata and property accessor logic for performance and code reuse.
- Added extensive unit tests for the new chain API and expression serialization, and reorganized test models and namespaces for clarity.
- Improved logging, error handling, and test infrastructure.
- Misc: Added settings for local builds, updated project files, and cleaned up obsolete code.
