47124623ab chore: bump version to 0.10.0 across all bindings (#710)
Update regorus core crate and all language bindings (ffi, java, python,
wasm, ruby, csharp) to version 0.10.0.

- Centralize C# package version via Directory.Packages.props
- Remove redundant C# version suffix properties from project files
- Regenerate all binding Cargo.lock files including Ruby
- Fix xtask to read/write RegorusPackageVersion from Directory.Packages.props
  instead of parsing VersionPrefix from the csproj (which now uses an MSBuild
  property indirection)

b9eca934a8 build(csharp): prepare NuGet package for nuget.org publishing (#668)
* build(csharp): rename NuGet package to Microsoft.Regorus

Align the NuGet package identity with the Microsoft.Regorus
namespace and the Microsoft.* reserved prefix on nuget.org
in preparation for publishing the package.

- Add explicit <PackageId>Microsoft.Regorus</PackageId>
- Update PackageVersion in Directory.Packages.props
- Update version bump regex for new package name

* build(csharp): default to ProjectReference for in-repo consumers

Use ProjectReference for Regorus.Tests, Benchmarks, TestApp,
and TargetExampleApp so that local development does not require
a pre-built .nupkg. PackageReference mode remains available via
/p:UsePackageReference=true for validating the packaged NuGet.

* build(csharp): add nuget.config with source mapping and xtask integration

Add explicit NuGet configuration to ensure in-repo builds always
resolve Microsoft.Regorus from the locally built package, even
after the package is published on nuget.org.

- Add nuget.config with <clear/> and packageSourceMapping
- Update xtask to copy .nupkg into local-packages/ directory
- Pass /p:UsePackageReference=true from xtask for CI testing
- Add restore validation step to the xtask test flow
- Add .gitignore for the local-packages directory

96360fa9d8 fix(bindings): add SafeHandleWrapper + memory growth checks; bump 0.9.1 (#571)
- Introduce SafeHandleWrapper with gating, short drain wait, and deferred release on last in-flight exit.
- Wire Engine/Program/Rvm/CompiledPolicy to wrapper (centralized handle use, interop helper).
- Add C# memory growth tests (using/finalizer paths) and extend xtask C# runner options.
- Add pooled marshalling utilities, ResultHelpers, and API cleanups; update versions/changelog.

Fixes #570. Closes #554

e688806ca0 chore: Keep regorus and binding versions in sync (#552)
Bump up the versions to 0.9.0 to match the C# binding version.

Also use central version management for C# projects

Also fix clippy lint errors

6dc505c88b build: Add xtask automation for binding version management (#491)
* build: Add xtask automation for binding version management

Introduces a dedicated xtask crate that keeps language binding versions
in sync with the core regorus crate, following the workflow pattern used
by rust-analyzer, gitoxide, and ripgrep.

Key features:
- Git-based change detection: compares binding source files against a
  base ref (merge-base with origin/main by default) plus unstaged/
  untracked files to identify which bindings have been modified
- SemVer-aware bumping: binding edits trigger a minor version increment
  (e.g. 0.5.1 → 0.6.0) under pre-1.0 semantics, signaling potential
  breaking changes; clean bindings simply align to the root version
- Multi-language support: updates Cargo manifests (Rust FFI, Java,
  Python, WASM, Ruby), Maven pom.xml (Java), Ruby version constants,
  and C# project files in a single pass
- CI integration: --check mode fails fast when manifests are out of
  sync, ensuring pre-commit and release-plz workflows catch stale
  versions before merge

Integration points:
- release-plz.toml: runs cargo xtask bindings --base-ref origin/main
  after bumping the root crate, so binding versions are updated
  atomically during the release process
- scripts/pre-commit: invokes cargo xtask bindings --check to block
  commits that would leave bindings out of sync
- .cargo/config.toml: defines cargo xtask alias for convenience

Documentation includes inline examples showing how version bumps behave
when bindings are ahead/behind the root, and notes that the minor
field acts as the major version under SemVer 0.y.z initial development
phase.

* build: refresh xtask tooling, workflows, and locks

- cargo xtask bindings: keep the binding version-sync pipeline intact
- cargo xtask update-deps: new helper to regenerate workspace/binding Cargo.lock files
- workflows: auto-detect the Java jar version in CI and temporarily disable the Ruby workflow
- lock files: refresh root + binding snapshots after the dependency sweep

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.

2a0b4ae6b5 feat! Mimalloc as the default allocator (#434)
This change integrates mimalloc as the default memory allocator for Regorus,
delivering significant performance improvements across all evaluation modes
and language bindings.

Technical Implementation:
- Build mimalloc in vendored mode from C sources (following QSharp approach)
- Implement GlobalAlloc trait for seamless Rust integration
- Add optional 'mimalloc' feature flag for conditional compilation
- Add comprehensive ACI benchmarks to measure evaluation performance

Performance Impact:

Rust Engine Evaluation:
- Single-threaded: ~29% improvement (423 vs 328 Kelem/s)
- Multi-threaded: Better scaling with reduced thread contention
- Fresh engines: ~24% improvement (56 vs 45 Kelem/s)

Rust Compiled Policy Evaluation:
- Single-threaded: ~41% improvement (426 vs 303 Kelem/s)
- Multi-threaded: Improved allocation efficiency under contention
- Fresh compilation: ~26% improvement (53 vs 42 Kelem/s)

C# FFI Bindings:
- Engine evaluation: ~27% improvement (279 vs 219 Kelem/s)
- Compiled policies: ~29% improvement (273 vs 211 Kelem/s)
- Better threading characteristics through improved underlying allocation

Key Benefits:
- Reduced allocation-related contention in multi-threaded scenarios
- More consistent performance across different thread counts
- Improved memory allocation efficiency for both native Rust and FFI workloads
- Better scaling characteristics for production deployments

The mimalloc integration provides substantial performance gains while
maintaining full compatibility with existing code through feature flags.

d561531613 feat: add multi-threaded evaluation benchmark suite with comprehensive C# implementation (#457)
This commit introduces a complete multi-threaded evaluation benchmark suite for both Rust and C# implementations of Regorus.

- Implemented engine evaluation benchmark with input and engine cloning strategies
- Implemented compiled policy evaluation benchmark with input cloning and shared compiled policy strategies.

- Created EngineEvaluationBenchmark.cs and CompiledPolicyEvaluationBenchmark.cs with time-based execution (3s warmup + 3s evaluation)
- Implemented configuration options matching Rust implementation (useClonedEngines, useSharedPolicies parameters)

- Created markdown analysis documentation with cross-platform performance analysis
- C# seems to achieve 58-89% of Rust performance on test machine.
