[ Service ] Fix issue where VM would hang in ServiceIsolate::Shutdown if shutdown immediately after starting up Running the VM with arguments that cause a quick failure _after_ the service isolate is started could result in the VM service starting and attempting to register a signal handler after the VM has started shutting down. The open port held by the signal handler prevented the message handler from shutting down, resulting in the main thread being blocked on a monitor in ServiceIsolate::Shutdown. Could be reproduced with the following commands: $ rm out/DebugX64/dartdev.dart.snapshot $ out/DebugX64/dart --observe hello_world.dart Change-Id: I70ddff73c98151bd7eff22064a23f897b4d6299f Reviewed-on: https://dart-review.googlesource.com/c/sdk/+/156923 Reviewed-by: Ryan Macnak <rmacnak@google.com> Commit-Queue: Ben Konyi <bkonyi@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.
