synurang 0.6.2

Flutter FFI + gRPC bridge for bidirectional Go/Dart communication

0.6.2

• Dart core recovery: Added StartGrpcServerOptions, CoreState, CoreRecoveryResult, recoverCoreAsync, getCoreState, and resetCoreState so apps can explicitly recover the embedded native core after an FFI timeout by resetting Dart helper isolates and issuing native Stop / Start calls.
• Timeout and shutdown handling: Per-call FFI timeouts now mark the core unhealthy, fail pending requests, close active server/plugin streams, and gate new RPCs with CoreUnavailableException or CoreRestartRequiredException. FfiClientChannel maps these recovery errors to gRPC unavailable.
• Recovery test coverage: Added a debug-only HangFor RPC plus recovery tests covering core state transitions, concurrent recoverCoreAsync callers, lifecycle calls while unhealthy, pending request cleanup, stream cleanup, and restartRequired behavior.
• Rust generator implementation: Added protoc-gen-synurang-ffi-rs, a Rust/prost reimplementation of protoc-gen-synurang-ffi, with make targets and parity tests that compare generated output, flag validation, and benchmark runs against the Go generator.

0.6.1

• C++ Lite support: Added a zero-dependency C++11 header-only runtime (cpp/synurang_lite.hpp) and lang=cpp,mode=lite code generation for protobuf messages and FFI service stubs.
• C++ Lite protobuf coverage: Generated lite headers now cover imported lite headers, well-known types, maps, repeated and packed fields, optional fields, oneofs, and streaming service helpers without requiring libprotobuf or gRPC.
• C++ generation tests: Expanded C++ generator tests to validate lite header generation for core/cache/native protos and syntax-check the generated headers with g++.

0.6.0

• Swift Lite support: Added zero-dependency Swift runtime packaging, Swift code generation, ProtoLite encoding/decoding, well-known type support, plugin host/stream APIs, and Swift generator/integration/stress tests.
• TypeScript support: Added TypeScript Lite schema/code generation and TypeScript FFI client generation, with generator coverage for enums, services, streaming methods, and well-known types.
• Plugin cancellation callbacks: Added on_cancel support for Rust and C++ plugin servers with regression tests covering cancellation callback behavior.

0.5.10

• C# Lite and stream worker fixes: Added C# Lite support for .NET 4.0, fixed internal visibility and repeated int32 code generation issues, and stabilized plugin stream scheduling with a dedicated worker plus regression tests.

0.5.6

• Concurrency and packaging fixes: Hardened plugin host/stream teardown across hosts, improved Android debug AAR packaging, and added Java/Rust host test coverage.

0.5.5

• TypeScript codegen: Added lightweight TypeScript schema constants for enums, field numbers, and full gRPC method paths, with generator coverage tests.

0.5.4

• Structured FFI errors: Replaced PluginError with FfiError carrying code, message, and grpc_code fields across all 6 languages (Go, Dart, C++, Rust, Java, C#).
• New wire format: Unary uses resp_len < 0 for errors (payload is serialized core.v1.Error); stream uses status < 0. Removes the old status-byte prefix overhead.
• Plugin stream interfaces: Go plugin server codegen now emits minimal PluginStream interfaces instead of grpc.ServerStream, removing the google.golang.org/grpc/metadata dependency from plugin code.
• gRPC status extraction: New pkg/ffierror package extracts structured errors from gRPC status details via reflection, avoiding a hard gRPC dependency.

0.5.0

• WASM & Rust native: Added WASM and Rust native support.
• ActiveX: Added ActiveX support.

0.4.0

• C# support: Added full support for C# via pure managed interop (NativeLibrary + Marshal).
• Pull-based C ABI: Dart plugin host with pull-based C ABI support for streaming.

0.3.0

• FFI without gRPC dependency: FFI transport layer no longer requires gRPC as a dependency.
• Android/Java support: Added full support for Android and Java via JNI.
• Process Mode improvements: Enhanced process mode functionality.

0.2.0

• Process Mode: Support for parent-child IPC via socketpair (Unix) and Named Pipes (Windows).
• Multi-language Support: Full support for C++ and Rust (including streaming) via FFI and Process Mode.

0.1.9

• In-process microservice (FFI + shared library).
• Apply template.

0.1.8

• Add runtime library and Go-to-Go FFI support.

0.1.7

• Add support for Android, iOS, macOS, and Windows platforms in pubspec.yaml and project structure.

0.1.6

• Fix: protoc-gen-synurang-ffi now correctly maps google/protobuf/ imports to package:protobuf/well_known_types/.
• Fix: Correct Go/Dart module paths in example code and proto definitions + dart_package option

0.1.5

• Include Dart generated files in the package.

0.1.4

• Fix internal import paths to use GitHub module path.

0.1.3

• Include generated Go code for remote usage.

0.1.2

• Fix go.mod configuration.

0.1.1

• Fix link in documentation.

0.1.0

• Initial release of synurang, a Flutter FFI + gRPC bridge for bidirectional Go/Dart communication.
