• Component: WebCore Misc.
• Status: RESOLVED FIXED

[Johan K. Jensen]

PerformanceEntryList should be iterable as per the current spec: https://www.w3.org/TR/2016/WD-performance-timeline-2-20160421/#idl-def-performanceentrylist.

Could these be Ref<PerformanceEntry>s?

do we have to sort everything?

Would be nice if this test had a description.

Why is this not const?

Why is this not const?

Some of the User Timing code uses PassRefPtr, so it should probably be updated in another patch.

Yes, per the spec we should sort them by start time. Entries gets added according to responseEnd.

Hm... Don’t see any reason why it isn’t.
