Anand Krishnamoorthi	80686d6ed1	feat(ffi): unwind safety: shield FFI entrypoints with panic guard (#546) ... This PR implements widely accepted Rust programming practices for dealing with panics across ABI (programming language) boundaries. - Add panic_guard.rs to wrap FFI calls and prevent panic across FFI/ABI boundary (undefined behavior). - Capture per-thread backtraces via a temporary panic hook - After a panic, subsequent invocations are poisoned. - Integrate with_unwind_guard across the engine, schema registry, and target registry exportis Signed-off-by: Anand Krishnamoorthi <anakrish@microsoft.com>	2026-01-21 09:20:10 +05:30
Anand Krishnamoorthi	091bbb2e5c	feat: Optimize C# binding interop (#488) ... - Introduce Utf8Marshaller helpers and SafeHandle wrappers so the managed API centralizes UTF-8 conversions and lifetime management for native pointers. - Update Engine, Compiler, CompiledPolicy, SchemaRegistry, and TargetRegistry to rely on the new marshaller/safe handles, tightening disposal and reducing transient allocations during interop calls. - Add allocation guard coverage in Regorus.Tests and report bytes/op in the compiled policy benchmark to surface future regressions.

Anand Krishnamoorthi	cc917ea75d	feat: Complete target system with C# bindings and resource inference (#458) ... * feat: Add Schema Registry and Validation Framework This commit introduces a comprehensive schema registry and validation framework, providing schema-based validation of resources and policy effects. - Thread-safe, in-memory registry for schema storage and management - Global registry patterns for effects and resources - Concurrent access with proper error handling - Unicode schema names support - JSON Schema-compliant validation for all primitive types - Advanced constraint validation (patterns, ranges, length limits) - Discriminated union support with anyOf schemas - Detailed error reporting with nested validation paths - Discriminated subobject validation for polymorphic schemas - **Registry Tests**: All registry operations - **Effect Tests**: Policy effect validation - **Resource Tests**: Resource validation - **Validation Tests**: Core validation engine - Thread-safety, error handling, integration scenarios, edge cases - **Dependencies**: dashmap, once_cell, regex - **Thread Safety**: Minimal locking with Rc<Schema> sharing - **Error Types**: TypeMismatch, OutOfRange, PatternMismatch, etc. - Complete schema registry and validation subsystem - Comprehensive test coverage - Foundation for policy validation in Regorus Benchmarks: - Criterion benchmarks for basic types, effects and Azure resources - Performance range: 3.22ns (string) to 34.74µs (Azure VM resource schema validation) - String withs patterns validation: 30.2µs. Need to explore whether regex caching helps bring this down. - Azure policy effects: 188ns-1.4µs Signed-off-by: Anand Krishnamoorthi <anakrish@microsoft.com> * feat: Complete target system with C# bindings and resource inference - Add comprehensive target system with TargetRegistry and target-aware compilation - Implement resource type inference from policy equality expressions - Create modular C# bindings with separate wrapper classes for each concept - Add thread-safe CompiledPolicy with reference counting for safe disposal - Enhance FFI with detailed error propagation and target functionality - Create TargetExampleApp demonstrating Azure Policy integration - Add CI/CD pipeline testing for all C# applications - Support target definitions with schema validation and resource selectors - Implement PolicyModule struct and target-aware compilation methods - Add comprehensive test coverage for target functionality Signed-off-by: Anand Krishnamoorthi <anakrish@microsoft.com> --------- Signed-off-by: Anand Krishnamoorthi <anakrish@microsoft.com>	2025-08-19 20:23:43 -05:00
