Bug 82735 – Web Inspector: [refactoring] factor our frame aggregation logic to TimelineFrameController

• Component: Web Inspector (Deprecated)
• Status: RESOLVED FIXED

[Andrey Kosyakov]

We'd like to reuse frame information in both overview pane and lower pane, so this should be moved out to a separate class.

It sounds like this change is not only factoring out what is claimed, but makes random changes to the code. Could you please split it?

> Source/WebCore/ChangeLog:8
> +        * WebCore.gypi: Added TimelineFrameController.js

Where is the new file?

> Source/WebCore/inspector/front-end/TimelineFrameController.js:52

Do we need to add this when panel is not shown?

Please remove the debug logging.

Please annotate this, btw we do for in all over the place.

Please annotate this.

> Source/WebCore/inspector/front-end/TimelineOverviewPane.js:-931
> -        var totalTime = 0;

Where did this method go?

> +                if (!longestFrame || longestFrame.cpuTime < this._frames[currentFrame].cpuTime)

What is longestFrame?

Well, those are not entirely random. I wouldn't like to spit it, as these are closely interconnected. I tried to do a better job of explaining what happens in the ChangeLog.

Fixing.

I addressed this as a separate change (bug 82861)

Oops. Thanks for spotting!

Done.

We used to do aggregation separately by frames or by top-level events in case we don't have frames. Now we just always simulate frames in TimelineFrameController, and the aggregation happens there as well -- except for the case when we need to show one bar per multiple frames.

The frame that took most CPU time.
