There were a couple of fixes to isolate handling recently. Is this still an issue? |
|
This comment was originally written by VadimTs...@gmail.com For me on dart-sdk revision 8121 (windows 7 32 bit) it works correctly now. |

It sounds like the recent isolate fixes corrected the problem. Closing the bug. Please reopen if the bug shows up again. Set owner to @turnidge. |

What steps will reproduce the problem?
import("dart:isolate");
class TestClass{
String strField;
TestClass(this.strField);
}
Future<String> someFunction(msg) {
print('someFunction called with param $msg');
Completer completer = new Completer();
// Next line caused dart vm hangup.
TestClass test = new TestClass('asdfadsf');
completer.complete("some dummy data");
return completer.future;
}
new_isolate() {
port.receive((msg, reply) {
Future f = someFunction(msg);
f.then((r)=>reply.send(r));
});
}
main() {
spawnFunction(new_isolate).call("testMessage").then((s)=>print("result = $s"));
}
What is the expected output?
>> someFunction called with param testMessage
>> result = some dummy data
What do you see instead?
-- Dart process hangs up.
Another twist: Script works successfully with line
-- TestClass test = new TestClass('asdfadsf');
modified to
-- var test = new TestClass('asdfadsf');
What version of the product are you using? On what operating system?
