1.2.2 #

  • Fix: compile() crashed (free(): invalid pointer) — bytecode buffer is now released with js_free.
  • Fix: Dart→JS conversion read freed memory when the same List / Map appeared more than once (non-cyclic shared references).
  • Fix (behavior): softReset() now replaces the JSContext on the same JSRuntime. Global var / let / const / class bindings and builtin prototype changes no longer survive, and builtins such as AggregateError, Iterator, Float16Array are no longer deleted. Native heap and engine instance id are kept.
  • Fix (behavior): timeout now also covers JS run while converting results (getters, Proxy traps). A throwing or interrupted getter makes the whole result an error (evaluate → isError, JSInvokable.invoke → throws JSError) instead of silently becoming null.
  • Fix: strings containing U+0000 are no longer truncated in either direction (native jsNewString / jsToCString take explicit lengths).
  • Fix: a Dart host function that throws no longer leaks its JSRef arguments.
  • Fix: the DartObject class id is allocated once per process instead of per context, removing per-engine class_array growth and the ~65k engine-creation limit.
  • Native: new exports jsBeginCall / jsEndCall; jsNewString and jsToCString signatures changed (all platform copies synchronized).
  • Tests / docs: example/test/review_regression_test.dart; review notes in doc/review/2026-09-13-code-review.md.

1.2.1 #

  • Lint: add missing type annotations on JSError constructor parameters (lib/quickjs/object.dart).
  • macOS/iOS build: avoid ObjC BOOL clash with QuickJS cutils.h (#if !defined(__OBJC__)).
  • Apple plugins: pure Objective-C registration (drop Swift) so SPM can compile C/C++ + ObjC in one target.
  • SPM: depend on Flutter’s FlutterFramework; public headers only under Sources/.../include/.
  • CocoaPods: public headers limited to Classes/; QuickJS headers private; header search path for cxx/.
  • macOS SPM: rename QuickJS VERSION → VERSION.txt (APFS case-insensitive clash with C++ #include <version>).

1.2.0 #

  • Pool default: JsEnginePoolConfig.resetOnRelease is now false (warm reuse; better process RSS under churn). Multi-tenant: prefer resetMode: soft (not hard as an RSS fix).
  • Soft wipe: JavascriptRuntime.softReset() + EngineResetMode (none / soft / hard) on JsEnginePoolConfig.resetMode. Prefer soft for multi-tenant isolation without full native rebuild; resetOnRelease: true still maps to hard.
  • Document soak RSS analysis: process RSS growth is dominated by hard reinitialize churn, not QJS heap / bridge counters.
  • Docs: production integration checklist (doc/wiki/guides/production-checklist.md), multi-tenant recipe updates, and example ProductionTenantWorker + tests.

1.1.1 #

  • Fix QuickJsRuntime2.close reference leak: release runtime refs via jsReleaseRuntimeRefs before freeing the JSContext.

1.1.0 #

  • Perf: JsTypedArrayTransfer and native owned-buffer paths for TypedArray / ArrayBuffer bridging.
  • Perf: evaluateJsonBatch for bulk JSON evaluate and bulk result copy.
  • Optimize object reference tables on the FFI boundary.
  • Fix Uint8ClampedArray double-copy path; expand TypedArray benchmarks (sizes, element types, non-zero offset, both directions).
  • Feat: native bridge allocation / copy counters (readBridgeStats / jsBridgeStats*) on all platforms.
  • Expand micro-benchmarks, soak/stress coverage, and performance wiki docs (measured results, standard benchmark_results/ layout).

1.0.2 #

  • Add a complete Flutter example application and include it in the published package.
  • Improve the GitHub Actions pub.flutter-io.cn publishing workflow for version tags.
  • Expand example-based test and stress-test coverage for package validation.
  • Add static analysis configuration and update development dependencies.
  • Bump embedded QuickJS to 2026-06-04 (all platforms: cxx/, cxx-windows/, iOS/macOS SPM trees).

1.0.1 #

  • Publish automatically from Github Action
  • Fix Non Linux and Windows head file problem

1.0.0 #

  • Package name: flutter_qjs_next (QuickJS engine bindings for Flutter).
  • QuickJS 2025-09-13 on all platforms; Windows tree aligned with Unix (dtoa, same sources).
  • TypedArray detection no longer depends on hard-coded JS_CLASS_* numeric IDs (constructor name + element size).
  • dart:ffi bindings for Android, iOS, macOS, Linux, Windows.
  • Array / TypedArray marshalling fast paths, evaluateJson, timeout/memory/stack limits, console logger, safer setTimeout channel (cached invokable runner).
  • Default memoryLimit 64 MiB (kDefaultJsMemoryLimit); pass 0 for unlimited.
  • Multi-engine: JsEnginePool / JsEnginePoolConfig with resetOnRelease via JavascriptRuntime.reinitialize().
  • Unique engine instance ids: qjs-<isolateHash>-<serial>-<us> (not identityHashCode).
  • QuickJsRuntime2.autoExecutePendingJobs (default true) drains Promise jobs after evaluate / call / bytecode / evaluateJson; documented in README.
  • Isolate module load: 1ms wait on IntPtr slot instead of 1µs pointer spin.
  • Dispose hardening: idempotent dispose, runtimeOpaques entry removed on free, disposed engines refuse re-init.
  • Rename residues: FLUTTER_QJS_NEXT_LIBRARY (legacy FLUTTER_QJS_ES2023_LIBRARY still accepted).
