Hi Guys,
Sometimes It can not resume execution from TerminateExecution.
In most time, It can resume execution after TerminateExecution as the
TerminateCancelTerminateFromThreadItself case do.
// Test that a single thread of JavaScript execution can terminate
// itself and then resume execution.
TEST(TerminateCancelTerminateFromThreadItself2) {
v8::Isolate* isolate = CcTest::isolate();
v8::HandleScope scope(isolate);
*// TerminateExecution here*
CcTest::isolate()->TerminateExecution();
v8::Local<v8::ObjectTemplate> global = CreateGlobalTemplate(
isolate, TerminateCurrentThread, DoLoopCancelTerminate);
v8::Local<v8::Context> context = v8::Context::New(isolate, NULL, global);
v8::Context::Scope context_scope(context);
CHECK(!CcTest::isolate()->IsExecutionTerminating());
// Check that execution completed with correct return value.
v8::Local<v8::Value> result =
CompileRun(isolate->GetCurrentContext(),
"try { doloop(); } catch(e) { fail(); } 'completed';")
.ToLocalChecked();
CHECK(result->Equals(isolate->GetCurrentContext(), v8_str("completed"))
.FromJust());
}
If I call TerminateExecution before create a new context. it cannot resume
unless call CancelTerminateExecution. It will failed to create context
with "Error installing extension 'v8/gc'"
// Test that a single thread of JavaScript execution can terminate
// itself and then resume execution.
TEST(TerminateCancelTerminateFromThreadItself2) {
v8::Isolate* isolate = CcTest::isolate();
v8::HandleScope scope(isolate);
v8::Local<v8::ObjectTemplate> global = CreateGlobalTemplate(
isolate, TerminateCurrentThread, DoLoopCancelTerminate);
v8::Local<v8::Context> context = v8::Context::New(isolate, NULL, global);
CHECK(!context.IsEmpty());
v8::Context::Scope context_scope(context);
CHECK(!CcTest::isolate()->IsExecutionTerminating());
// Check that execution completed with correct return value.
v8::Local<v8::Value> result =
CompileRun(isolate->GetCurrentContext(),
"try { doloop(); } catch(e) { fail(); } 'completed';")
.ToLocalChecked();
CHECK(result->Equals(isolate->GetCurrentContext(), v8_str("completed"))
.FromJust());
// TerminateExecution here
CcTest::isolate()->TerminateExecution();
v8::Local<v8::Context> context2 = v8::Context::New(isolate, NULL, global);
result =
CompileRun(context2,
"try { doloop(); } catch(e) { fail(); } 'completed';")
.ToLocalChecked();
CHECK(result->Equals(context2, v8_str("completed"))
.FromJust());
}
The above code wil also have the same error unless I call
CancelTerminateExecution
after TerminateExecution.
So it won't resume execution if there is no javascript code. Is that right?
Is there any flag to know whether i need to call CancelTerminateExecution?
