For applications that want to have arbitrary number of isolates call into native code that may be blocking, we expose the API functions that allows those native threads to exit an isolate before running long/blocking code. Without the ability to exit/re-enter isolate, one may experience deadlocks as we have a fixed limit on the number of concurrently executing isolates atm. In the longer term we may find a way to do this automatically with low overhead, see [0]. But since those API functions are quite stable and we already expose e.g. `Dart_{Enter,Exit}Scope`, I don't see a reason not to expose `Dart_{Enter,Exit}Isolate`. Difference to original CL: Do use STL synchronization primitives (as the ones in runtime/bin are not always available in shared libraries) [0] Issue https://github.com/dart-lang/sdk/issues/51261 Issue https://github.com/dart-lang/sdk/issues/51254 TEST=ffi{,_2}/dl_api_exit_enter_isolate_test Change-Id: Id817e8d4edb3db35f029248d62388cbd0682001d Reviewed-on: https://dart-review.googlesource.com/c/sdk/+/294980 Reviewed-by: Daco Harkes <dacoharkes@google.com> |

Dart
A client-optimized language for fast apps on any platform
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).
License & patents
Dart is free and open source.
