I'm trying to set a timeout for scripts running in an Isolate using the
Locker + Preemption + TerminateExecution, but there are some cases where it
looks the script isn't being pre-empted and killed. This script:
var s = "";
while (true) {
s += "hello";
}
gets killed properly, while this script never gets terminated:
while (true) {
var a = new Array();
a[0x3ffffffe] = 0;
}
I've added some logging and the body of loop gets run often, but the
isolate never gets termination signal. It looks like the thread is never
getting pre-empted (I tried to lock this isolate in another thread and that
thread never wakes up).
I grabbed the source for v8 early last week and the latest code seems to
still have this problem. Is this expected behavior?
Thanks,
Shyam
