Testing profiling against v8 4.6.88.
I have functions that are exposed through accessor callbacks. If a native
function is set for multiple accessor properties, the last property shows
up as the function name in the CpuProfileNode, regardless what name you set
to the function returned by the accessor function. For example:
global->SetAccessor(
v8::String::NewFromUtf8(isolate, "print", v8::NewStringType::kNormal)
.ToLocalChecked(),
getFunction);
global->SetAccessor(
v8::String::NewFromUtf8(isolate, "read", v8::NewStringType::kNormal)
.ToLocalChecked(),
getFunction);
Now "get read" is the function name in CpuProfileNode although print is
called.
Test script:
function isPrime(num) {
for (var count = 2; count < num; count++)
if (num % count == 0) return false;
return true;
};
var total = 0;
for (var i = 2; i < 100000; i++) {
if (isPrime(i)) {
print(i);
total++
}
};
total;
TotalHitCount:2233
FunctionName:(root)
LineNumber:0

FunctionName:(program)

Given that an accessor callback takes a property name, it should allow one
native function to handle multiple properties. Is this a bug, or am I
doing something wrong?
