Bug 80856 – Split the extra logic out of RenderObjectChildList::updateBeforeAfterContent

• Component: Layout and Rendering
• Status: RESOLVED FIXED

[Igor Trindade Oliveira]

Currently, updateBeforeAfterContent has a complex logic, it creates and updates the before and after elements. 
Splitting the extra logic out of  RenderObjectChildList::updateBeforeAfterContent, makes it easier to understand.

The rest of the change looks fine but I would like a green EWS!

I don't think this change is right. We used to bail out if |generatedContentContainer| was not allowed by |owner| and now we don't - because it's missing a NULL-check. I guess that's why the EWS is unhappy.

Arguably this doesn't add much so I would advise just dropping this part of the change unless you need that for your refactoring.

Btw, I don't know what the "extra logic" is. I guess it should be either
* Split some logic out of RenderObjectChildList::updateBeforeAfterContent
* Extra part of the generated content handling logic out of RenderObjectChildList::updateBeforeAfterContent

Useless line (not your fault as prepare-ChangeLog has been sick for some time).

> Source/WebCore/ChangeLog:14
> +        (WebCore::createBeforeAfterGeneratedContentContainer):

Stale entry.

> Source/WebCore/rendering/RenderObjectChildList.cpp:350
> +    if (child && child->style()->styleType() == type) {

Nit: This could use an early return.
