Bug 234015 – Propagate app-initiated state to new ResourceRequests

• Component: WebKit Misc.
• Status: RESOLVED FIXED

[Brent Fulgham]

While reviewing logging we have found that some ResourceRequest objects are missing the correct state for app-initiated loads. Typically, these are cases where a new ResourceRequest is created from a URL string, losing the context that came with the original load (or the context of the page triggering the load).

This patch corrects a number of such cases.

Thanks for covering these cases. r=me with gtk/wpe/wincairo/win fixes.

Seems like you may need to #include DocumentLoader.h here for GTK and WPE.

We set this in updateRequestAndAddExtraFields which is called below, so no need to do it here.

Will do!

Ah! Good catch. Will remove.

This debugging code should not be landed.

One thing to note is only the main frame's document loader holds the correct value, so there may be some places where we need to check that value instead of the current document's loader.

> Source/WebCore/loader/FrameLoader.cpp:978
> +        frameLoadRequest.resourceRequest().setIsAppInitiated(*appInitiated);

I think this one is unnecessary because loadURL() called below will call updateRequestAndAddExtraFields which will set the value.

> Source/WebKit/NetworkProcess/cache/NetworkCacheSubresourcesEntry.cpp:50
> +    encoder << m_isAppInitiated;

Good catch.

I think this will also always end up in a frame loader function that calls updateRequestAndAddExtraFields, so it is not needed.

Ditto

> Source/WebCore/loader/NavigationScheduler.cpp:261
> +            resourceRequest.setIsAppInitiated(documentLoader->lastNavigationWasAppInitiated());

Ditto.

> Source/WebCore/loader/NavigationScheduler.cpp:378
> +            resourceRequest.setIsAppInitiated(documentLoader->lastNavigationWasAppInitiated());

Ditto.

> Source/WebCore/loader/NavigationScheduler.cpp:482
> +            resourceRequest.setIsAppInitiated(documentLoader->lastNavigationWasAppInitiated());

Ditto.

> Source/WebCore/page/DOMWindow.cpp:2545
> +            resourceRequest.setIsAppInitiated(documentLoader->lastNavigationWasAppInitiated());

Ditto here. changeLocation calls loadFrameRequest which calls loadURL or loadPostRequest which will both eventually call updateRequestAndAddExtraFields.

> Source/WebCore/page/DragController.cpp:300
> +        resourceRequest.setIsAppInitiated(documentLoader->lastNavigationWasAppInitiated());

Here too.
