Bug 151435 – Web Inspector: Promise callbacks are not profiled

• Status: RESOLVED
• Resolution: DUPLICATE
• Component: Web Inspector

[Joseph Pecoraro]

* SUMMARY
Promise callbacks are not profiled

* TEST
<button id="x">Click</button>
<script>
window.x.onclick = function() {
    Promise.resolve(100).then(function() {
        alert("test");
    });
};
</script>

* STEPS TO REPRODUCE
1. Inspect test page
2. Start timeline
3. Click button
4. Dismiss alert
5. Stop timeline
  => Scripts Timeline does not show the promise handler

* NOTES
Likely places to look are:
- JSJobMicrotask::run - JSJob.cpp
- JSPromiseDeferred::resolve and JSPromiseDeferred::reject - JSPromiseDeferred.cpp
- JSInternalPromise::then - JSInternalPromise.cpp

I am addressing this in bug 151899.

To be clear that bug profiles it in ScriptProfiler, it won't yet show up in a Page inspection until we move Page inspection to using ScriptProfiler. A follow-up to that.
