Pass around RenderStyle by const-reference inside SVGInlineTextBox.

• Component: SVG
• Status: RESOLVED CONFIGURATION CHANGED

[Andreas Kling]

Functions that immediately start by asserting that some Foo* argument is non-null are silly.

The reviewed by line should precede the description of the change log entry.

> +    const RenderStyle* selectionStyle = &style;

This local variables isn't used in a meaningful way in this function. I mean, we only assign a value(s) to it and never reference it. Shouldn't we be referencing this variable instead of |style| in SVGInlineTextBox::selectionRectForTextFragment() and GraphicsContext::fillRect() below?

> Source/WebCore/rendering/svg/SVGInlineTextBox.cpp:273
> +    const RenderStyle* selectionStyle = &style;
>      if (hasSelection) {
>          selectionStyle = parentRenderer.getCachedPseudoStyle(SELECTION);
>          if (selectionStyle) {

This is OK as-is. We should consider simplifying this code so as to remove an extraneous assignment to selectionStyle when parentRenderer.getCachedPseudoStyle(SELECTION) (on line 272) returns null. We can do this in another patch.

Will you land this kling?

[Ahmad Saleem]

It seems that this r+ patch didn't landed.

Is this needed anymore? Thanks!

[Ahmad Saleem]

It seems to be done - https://searchfox.org/wubkat/rev/7cf0e3722de99a6fc09380aae193381be6733ebb/Source/WebCore/rendering/svg/SVGInlineTextBox.h#78

Marking this as 'REOSLVED CONFIGURATION CHANGED'.
