Bug 66167 – [Chromium] Add WebFrameClient::didAdoptURLLoader() notification

• Component: WebKit Misc.
• Status: RESOLVED FIXED

[Dmitry Titov]

In order to update routing ids for loading requests when iframe is reparented between WebFrames, we need to add a notification to WebFrameClient to tell the WebFrame it now owns a specified resource in progress.

This patch won't compile w/o previous one from bug 66165 since it uses a new RessourceLoader* parameter of FrameLoaderClient::transferLoadingResourceFromPage

Perhaps this should be adoptURLLoader... or, maybe even better:  didAdoptURLLoader.

The second form suggests that this is informative.  The client does not necessarily need to do anything here unless it has special needs.  Chromium has special needs.  DRT does not.

did you really mean for this to be a static method on ResourceHandleInternal?

Updated patch

Renamed method to didAdoptURLLoader.

As for static method - I hope there is a better way, I'm using the fact that ResourceHandleInternal is a 'friend' to ResourceHandle, to pull the 'd' member. We currently don't have access to it otherwise. Do I miss something?

The thing that confuses me is that at this callsite, you are not doing ResourceHandleInternal::WebURLLoaderFromResourceHandle.  so, there must be a missing file that defines the global WebURLLoaderFromResourceHandle function?

Very true. It won't compile. My bad.

How do we crack open ResourceHandle?

Patch

As discussed offline, created ResourceHandleInternal.h in chromium/src.

The impl of the class still lives in ResourceHandle.cpp, I can pull it out into separate file if desired.
Data members of ResourceHandleInternal are made private, needed accessors are added.

The complete fix consists of WebKit patches for bug 66165 and this one, and also Chromium side here: http://codereview.chromium.org/7647003/

As for m_state member, it's used internally in implementation of Chromium's ResourceHandleInternal to track the states. I can see it changing values and then asserting on them in WebKit/chromium/src/ResourceHandle.cpp

"This happens when an iframe, that is loading a subresource, is transferred between windows."
