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

Sample screenshot

Make inspector show percents along with counts/sizes instead of switching between two.
The '%' button on the status bar should switch percents on/off.

It seems to clutter UI to me.

[Alexei Filippov]

1. There's quite a large unused space in inspector. So it makes sense to show the percents there without the need to switch back and forth.
2. The percents are shown in gray, so the main figures are easily distinguishable.
3. You can turn it off with the '%' button.

Looks good to me with nits.

> Source/WebCore/inspector/front-end/DetailedHeapshotView.js:942
> +        return this.showShallowSizeAsPercent && this.showRetainedSizeAsPercent;

Is it possible to have a single flag for percent?

> LayoutTests/inspector/profiler/detailed-heapshots-comparison-show-all.html:42
> +                countA = parseInt(row.data["addedCount"]);

I'd rather fix the expectations.

Why did this change? You should prefer message format to the concatenation.

> Source/WebCore/inspector/front-end/DetailedHeapshotView.js:203
> +        count: { title: WebInspector.UIString("Objects Count"), width: "90px", sortable: true },

you should add this new string to the English.lproj/localizedStrings.js

> +        sizeDelta: { title: "Size Delta", width: "72px", sortable: true }

ditto
