Bug 223510 – Cannot login to microsoftonline.com without allowing storage access

• Status: RESOLVED
• Resolution: FIXED
• Component: WebKit Misc.

[Kate Cheney]

If a user denies storage access on sites with the storage access quirk, we cancel the click and they can't login. We should consider changing this behavior, because some sites which require storage access share login flows with sites that do not require storage access.

I don't think we should have a "page" prefix for WebPage functions. This is not a common pattern.

> +    bool pageIsParentProcessAFullWebBrowser();

Can this be const?

I needed some way to distinguish it from the isParentProcessAFullWebBrowser function in DefaultWebBrowserChecks.h. I can use something slightly different like isParentProcessAWebBrowser().

I wouldn't say "allow login" since the browser doesn't decide that. I'd say "don't cancel the click" instead.

Ditto on allowing login.

This can be just isParentProcessAFullWebBrowser = MacApplication::isSafari().

I looked and other functions use m_frame directly too so should be fine.

Thanks! I am also going to replace "tab" with "web content process" in the ChangeLog because a web content process can host multiple tabs sometimes.

Yes, it's a Ref so it can't be null.
