[vm] Fix some async* semantics issues: Only run generator if there's active subscription (not paused/cancelled) This fixes an issue where VM would run the async* generator after a `yield` / `yield*` even though the subscription may be paused or cancelled. Furthermore this fixes an issue where `StackTrace.current` used in async* generator crashes VM and/or produces truncated stack trace. This fixes the following existing tests that were failing before: * co19/Language/Statements/Yield_and_Yield_Each/Yield_Each/execution_async_t08 * co19/Language/Statements/Yield_and_Yield_Each/Yield_Each/execution_async_t09 * co19/Language/Statements/Yield_and_Yield_Each/Yield_Each/execution_async_t10 * language/async_star/async_star_cancel_test * language/async_star/pause_test Issue https://github.com/flutter/flutter/issues/100441 Issue https://github.com/dart-lang/sdk/issues/48695 Issue https://github.com/dart-lang/sdk/issues/34775 TEST=vm/dart{,_2}/causal_stacks/flutter_regress_100441_test Change-Id: I73f7d0b70937a3e3766b992740fa6fe6e6d57cec Reviewed-on: https://dart-review.googlesource.com/c/sdk/+/239421 Reviewed-by: Lasse Nielsen <lrn@google.com> Commit-Queue: Martin Kustermann <kustermann@google.com>
Dart is:
Optimized for UI: Develop with a programming language specialized around the needs of user interface creation.
Productive: Make changes iteratively: use hot reload to see the result instantly in your running app.
Fast on all platforms: Compile to ARM & x64 machine code for mobile, desktop, and backend. Or compile to JavaScript for the web.
Dart's flexible compiler technology lets you run Dart code in different ways, depending on your target platform and goals:
Dart Native: For programs targeting devices (mobile, desktop, server, and more), Dart Native includes both a Dart VM with JIT (just-in-time) compilation and an AOT (ahead-of-time) compiler for producing machine code.
Dart Web: For programs targeting the web, Dart Web includes both a development time compiler (dartdevc) and a production time compiler (dart2js).
Dart is free and open source.
