Bug 97547 – Code inside FrameLoaderClient::canShowMIMEType() implementations can be shared among different WK ports

• Component: WebCore Misc.
• Status: RESOLVED FIXED

[Mikhail Pozdnyakov]

Currently the code inside FrameLoaderClient::canShowMIMEType() implementations is pretty much similar among
different WK ports:
EFL, Qt, GTK, WinCe have following snippet inside FrameLoaderClient canShowMIMEType() function:
MIMETypeRegistry::isSupportedImageMIMEType(type)
            || MIMETypeRegistry::isSupportedNonImageMIMEType(type)
            || MIMETypeRegistry::isSupportedMediaMIMEType(type)

WK2 has similar logic inside WebKit::WebPageProxy::canShowMIMEType()
    if (MIMETypeRegistry::isSupportedNonImageMIMEType(mimeType))
        return true;

    if (MIMETypeRegistry::isSupportedImageMIMEType(mimeType))
        return true;

    if (mimeType.startsWith("text/", false))
        return !MIMETypeRegistry::isUnsupportedTextMIMEType(mimeType);

Think it would be wise to have a new function inside MIMETypeRegistry, that would encapsulate this logic.

Isnt that like a really weird name. What if it contains only javascript?

How about 'isMIMETypeHandledByWebPage' ?

Are all the other exports still needed?

Looks MIMETypeRegistry::getUnsupportedTextMIMETypes does not need to be exported anymore.

Having an IRC discussion with Kenneth came to conclusion that the already used "canShowMIMEType" looks like the most appropriate name for the new function. 
Do not require any flags as need to get mangled name for the new function from MAC bot first :)
