[Chromium] Call isLinkVisited directly

• Component: WebKit Misc.
• Status: RESOLVED FIXED

[Mark Pilgrim (Google)]

As part of the PlatformSupport refactoring (see bug 82948), I need to migrate isLinkVisited out of PlatformSupport.cpp/h and into... somewhere. Or do I? Example usage is here: http://trac.webkit.org/browser/trunk/Source/WebCore/page/PageGroup.cpp#L175 As you can see, Chromium is a special case. Every other port uses m_visitedLinkHashes, but Chromium routes through PlatformSupport. Now, if we want to continue special-casing Chromium, I could create a class in platform/VisitedLinksSupport.cpp/h and another in platform/chromium/VisitedLinksSupportChromium.cpp that contained a static isLinkVisited function that routes to WebKit::Platform::current()->isLinkVisited(...).  I've followed that pattern numerous times (StatsCounter, MemoryUsageSupport, TraceEventSupport). Or should we discuss removing the special case for Chromium and handling visited links the same way as other ports? (I don't know if this is possible or desirable; I'm just looking for guidance on how to proceed.)

PlatformSupport::visitedLinkHash() is probably also affected by this decision.

I'm pretty sure that we need to maintain the Chromium specific code paths.  The reason for this is that we use a shared memory buffer on the Chromium-side to implement these functions.

OK, new VisitedLinkSupport.cpp/h and VisitedLinkSupportChromium.cpp to house isLinkVisited function inside WebCore. Same pattern as, for example, bug 84376.

Looks like you've got some compile troubles.

> Source/WebCore/page/PageGroup.cpp:179
> -    return PlatformSupport::isLinkVisited(visitedLinkHash);
> +    return VisitedLinkSupport::isLinkVisited(visitedLinkHash);

I wonder if we should move this into the client.  This seems more like something the ChromeClient should worry about...

If we are going to keep this as a static, we should use a better name than VisitedLinkSupport though.  Perhaps VistedLinks?

Fixed missing include, should fix compile problems. Also renamed VisitedLinkSupport to VisitedLinks.

Did the entry in the header already move?
