Bug 63276 – Add NSURLRequest wrapper in ResourceRequest when USE(CFNETWORK) is enabled

• Component: Platform
• Status: RESOLVED FIXED

[Pratik Solanki]

This is part of the move to the CFNetwork based loader on Mac - bug 51836. In order to send back NSURLRequest objects to WebKit on Mac, we need to have a wrapper NSURLRequest in ResourceRequest.

Unofficial r=me!

Why does this need to be mutable?

> +        mutable RetainPtr<NSURLRequest> m_nsRequest;

Same question here

This would be cleaner as a #elif PLATFORM(MAC)

> Source/WebCore/platform/network/mac/ResourceRequestMac.mm:69

It is unfortunate that we have to allocate a new NSURLRequest every time we update it, since doUpdatePlatformRequest is called quite often. We are already doing something similar in ResourceRequestCFNet.cpp. However, I don't think that issue needs to be addressed in this patch.

Hmm. doesn't look like its needed anymore. I'll remove it.

I'll remove the mutable here as well.

ok

Well, we create a CFURLRequestRef in doUpdatePlatformRequest() so we have to create an NSURLRequest as well.

In one part of the patch, the call to updateNSURLRequest() is protected by #if PLATFORM(MAC)/#endif, and in another place it's not.

I don't think this method should be defined, then just add  #if PLATFORM(MAC)/#endif where it's called (which is one more place below).

Add #if PLATFORM(MAC)/#endif here.

Will the NSURLRequest go away completely if PLATFORM(MAC) switches to USE(CFNETWORK)?

Ok.

No, WebKit needs the NSURLRequest on Mac. The way these patches work is that they expose the obj-c classes to WebKit while using CF code for the actual networking in WebCore. So we'll need NSURLRequest.
