Bug 83404 – Remove dead code in SVGCSSParser

• Component: SVG
• Status: RESOLVED FIXED

[Rob Buis]

The CSSPropertyColor handling code is unreachable, because CSSParser handles it. I think this was kept as a possible way to deal with SVGColor interface (bug 15012), but since it is deprecated this code is really not needed anymore.

CSSPropertyColor is already handled by CSSParser I guess, so we never reach this code path?
If so, please include this in the ChangeLog ("why" change logs are better than "what" change logs). Still r=me.

Ah, just saw you posted a new patch, r=me for that as well, as it resolved my issue :-)

This is not needed, is it?

> LayoutTests/svg/custom/script-tests/currentColor-on-color.js:19
> +shouldBeEqualToString("document.defaultView.getComputedStyle(rectElement).color", "rgb(0, 128, 0)");

s/document.defaultView// (it's not need).

I think it is. Read the LayoutTests Changelog :) Basically we inherit the color=currentColor CSS3 behaviour from CSSParser.cpp (matches what FF does), and I agreed with Dirk to make a regression test for that since we are giving up dealing with color property in SVGCSSParser.cpp, based on his bug and closing of bug 15012.

Great! Will fix before landing.
Cheers,

Rob.
