Instead of storing the context here, I think it makes more sense to just pass the context the this method as we do everywhere else.

I don't think there is any reason for these messages to go to the WebPageProxy, they should be able to go right to the WebContext from the WebProcessProxy.


r- to address these issues.

Why not use hasValidProcess() here, since you added it?

Can page() be 0? What should we do in that case?

No need for the "inline" here. Functions defined inside the class definition are automatically treated as if "inline" was specified.

Are there some other clients this can be paragraphed with so it doesn't need its own?

I'm a little mystified by the version checks. It seems that if someone passes in version 1 or greater of the structure we'll ignore it completely. That does not seem to be what version is for. This is probably not new to your patch -- maybe we're doing this throughout.

Perhaps setting this to false should clear the existing visited links?

Indeed!

It can't be - We actually translated a frameID to a WebFrame by asking a WebPage before calling this method.

But I'm adding assertions to this effect.

The injectedbundleclient is the only other client, but I felt it made slightly more sense to paragraph it with its companion m_injectedBundlePath

Not new to my patch, we do it throughout - I'm equally mystified.

WebCore does this already.
