Bug 221909 – Add support for non app-bound requests

• Component: WebKit Misc.
• Status: RESOLVED FIXED

[Kate Cheney]

We should add support for specifying non app-bound requests, mainly populating sub resource loads with this value.

Should probably be moved before the Optional data member and with the other bits for better packing.

Internally this is IOS_FAMILY only, so why is the SPI both macOS too?

Ok, I will move this.

Mistake, I'll remove it.

I get this complaint from the style bot: Inline functions should not be annotated with WEBCORE_EXPORT. Remove the macro, or move the inline function definition out-of-line. Moving back to cpp file for this reason.

Ignore stylebot in this case.

I think it may be causing failures on the debug bot now:

ERROR: WebCore has a weak external symbol in it (/Volumes/Data/worker/macOS-Catalina-Debug-Build-EWS/build/WebKitBuild/Debug/WebCore.framework/Versions/A/WebCore)
ERROR: A weak external symbol is generated when a symbol is defined in multiple compilation units and is also marked as being exported from the library.

Please move to header.

Drop WEBCORE_EXPORT once you've inlined in the header.

I believe the correct fix is to stop the WEBCORE_EXPORT on the inline function in the header, as the style bot suggested.

I see. I didn't realize that WEBCORE_EXPORT is not needed if the function is inlined in the header, but that makes sense.

I am no familiar with the 'app-bound' feature at all but I am wondering why we have the negative here in the API. Why aren't we using "isAppBound" instead of "isNonAppBound". Seems to be (at least) that it would be more readable.

> Source/WebKit/Shared/NavigatingToAppBoundDomain.h:30

Ugh. Please reverse the No and Yes here so that 0 means No and 1 means Yes.

> Source/WebKit/UIProcess/API/Cocoa/WKWebViewTesting.mm:312
> +- (void)_isNonAppBoundRequest:(void(^)(BOOL))completionHandler

Again, I wish this was called isAppBoundRequest

> Source/WebKit/UIProcess/API/Cocoa/WKWebViewTesting.mm:314
> +#if PLATFORM(IOS_FAMILY)

Seems like this should cover those whole _isNonAppBoundRequest method implementation now that this method is iOS only?

> Source/WebKit/UIProcess/WebPageProxy.h:2901
> +    bool m_requestIsNonAppBound { false };

It is super fishy don't have a flag like this on the WebPageProxy. A page is so far from a request. You can make many requests in a single page.

> Source/WebKit/WebProcess/WebPage/WebPage.h:2237
> +    bool m_requestIsNonAppBound { false };

Again, I don't see how a request being app bound is related to a WebPage since you can make MANY requests in a WebPage.

Hmm, yes I left it in the negative to match the call in CFNetwork but I am thinking now it would be better to reverse it at those call sites only and then store it as isAppBound in WebKit.

I am sorry for my past self.

Right, will fix.

I use it as a holding place after WebPageProxy::loadRequest is called until it gets sent to the WebPage and stored in the main frame's document loader. Maybe "currentRequestIsNonAppBound"?

Or, currentRequestIsAppBound if I reverse it.

Does it reset after we're done navigating? If not, it sounds like it should be lastRequestWasAppBound, no? or maybe even better: lastNavigationWasAppBound. I personally find "request" at page level to be confusing (although I understand it matches WKWebView.loadRequest API). Internally, the loadRequest results in a main frame navigation.

I agree this makes more sense.

These need null checks

It will always use the Internal SDK?

I think this looks great, but I don't think we want to limit this concept to iOS-only. r- to fix that, but otherwise this is ready to go.

> Source/WebCore/loader/DocumentLoader.h:423
> +#if PLATFORM(IOS_FAMILY)

I don't think this concept is limited to IOS_FAMILY only, is it?

> Source/WebCore/loader/DocumentLoader.h:666
> +#if PLATFORM(IOS_FAMILY)

Ditto.

> Source/WebKit/NetworkProcess/NetworkProcess.cpp:1363
> +    parameters.request.setIsAppBound(lastNavigationWasAppBound == LastNavigationWasAppBound::Yes ? true : false);

nit: I think you just need "lastNavigationWasAppBound == LastNavigationWasAppBound::Yes" (the additional ternary operation is redundant)

> Source/WebKit/NetworkProcess/NetworkResourceLoader.cpp:880
> +        redirectRequest.setIsAppBound(request.isAppBound());

I wonder if the test is really necessary before setting. Maybe just always set the app-bound state of the redirect to match the original request, since we always want the redirect to have the state of the originating request.

> Source/WebKit/Shared/WebPageCreationParameters.cpp:174
> +#if PLATFORM(IOS_FAMILY)

I don't think this is limited to IOS.

> Source/WebKit/Shared/WebPageCreationParameters.h:245
> +#if PLATFORM(IOS_FAMILY)

Ditto.

> Source/WebKit/UIProcess/WebPageProxy.cpp:1322

I don't think this should be iOS-only

Nit: Unneeded whitespace change.

I don't thin this should be iOS-only

Your test says APPLE_INTERNAL_SDK only, so it seems like yes?

Not iOS-only
