Bug 195637 – Drop legacy WebCore::toRegistrableDomain() utility function

• Status: RESOLVED FIXED

[Chris Dumez]

Drop legacy WebCore::toRegistrableDomain() utility function. Call sites should be constructing a WebCore::RegistrableDomain instead.

Is there a reason why you prefer creating two objects over comparing one with the matches() function?

> Source/WebCore/loader/CrossOriginAccessControl.cpp:233
> +        if (RegistrableDomain { response.url() } != RegistrableDomain::uncheckedCreateFromHost(origin.host()))

Ditto. You have the response URL.

> +        if (SecurityPolicy::shouldInheritSecurityOriginFromOwner(frame->document()->url()) || RegistrableDomain { frame->document()->url() } == registrableDomain)

Ditto.

> +    request.setIsSameSite(RegistrableDomain { initiator->siteForCookies() } == RegistrableDomain { request.url() });

Ditto.

Yay, a FIXME gets fixed.

> Source/WebCore/platform/network/cf/ResourceRequestCFNet.cpp:289
> +    m_sameSiteDisposition = !siteForCookies ? SameSiteDisposition::Unspecified : (RegistrableDomain { siteForCookies.get() } ==  RegistrableDomain { m_url }) ? SameSiteDisposition::SameSite : SameSiteDisposition::CrossSite);

Here you could also use the faster matches() function.

> Source/WebCore/platform/network/cocoa/ResourceRequestCocoa.mm:92
> +    m_sameSiteDisposition = siteForCookies.isNull() ? SameSiteDisposition::Unspecified : ((RegistrableDomain { siteForCookies } == RegistrableDomain { m_url }) ? SameSiteDisposition::SameSite : SameSiteDisposition::CrossSite);

Ditto.

> Source/WebKit/NetworkProcess/cocoa/NetworkDataTaskCocoa.mm:148
> +    return WebCore::RegistrableDomain { request.url() } != request.firstPartyForCookies();

If request.firstPartyForCookies() returns a RegistrableDomain, you could use matches() here too.

> Source/WebKit/UIProcess/WebProcessPool.cpp:1312
> +            updatedRequest.setIsSameSite(RegistrableDomain { initiatingPageURL } == RegistrableDomain { request.url() });

Can use matches().

> Source/WebKit/UIProcess/WebProcessPool.cpp:2299
> +    if (!sourceURL.isValid() || !targetURL.isValid() || sourceURL.isEmpty() || sourceURL.protocolIsAbout() || RegistrableDomain { sourceURL } == targetRegistrableDomain)

Ditto.

> Source/WebKit/WebProcess/WebCoreSupport/WebFrameLoaderClient.cpp:398
> +    if (m_hasFrameSpecificStorageAccess && RegistrableDomain { currentUrl } != RegistrableDomain { newUrl }) {

Ditto.

I merely did not know about it. I'll update the patch, thanks for looking.

Nit: I would name this areRegistrableDomainsEqual. I think seeing is/are as a prefix helps show that what follows is a boolean condition, and I think that's how Apple API is typically written.
