Bug 32250 – Rename dom/ClassNames.{cpp,h}

• Component: WebCore Misc.
• Status: RESOLVED FIXED

[Nate Chapin]

ClassNames used to be named AtomicStringList, but was renamed (http://trac.webkit.org/changeset/28722) to reflect the fact that it was only being used for class names at the time.

Its behavior, however, matches what is required of HTML5 space separated lists (http://www.whatwg.org/specs/web-apps/current-work/#space-separated-tokens).  I used ClassNames for implementing <a rel="noreferrer"> support (https://bugs.webkit.org/show_bug.cgi?id=28986), with the understanding that ClassNames would need to be renamed again.

The only remaining question is what the new name should be.  I was thinking something like SpaceSplitString, but I could also revert it to AtomicStringList.  I'm not picky.

Probably best to e-mail webkit-dev for more people to see the question.

Rename ClassNames to SpaceSplitString

I think I correctly modified all the build files, but is there a preferred way to confirm that?

These changes are incorrect. The "14" is the length of the string "ClassNamesData", so it should be "20" instead. But really this file should not be updated. There's no way for the "average person" to generate this. It has to be generated by running the framework in a test environment. Stephanie Lewis normally does it.

I don't understand how the name change triggered the need for an additional include.

I'm going to say r=me but I think both of those are errors. The build file changes look right to me.

That seems reasonable.  I'll change both prior to landing.  Thanks!
