Bug 46430 – Platform specific ResourceResponse and ResourceRequest can't fully cross threads.

• Component: Platform
• Status: RESOLVED FIXED

[Michael Nordman]

Platform specific ResourceResponse and ResourceRequest classes have no means to copy their data via across threads. The CrossThreadResourceRequestData and CrossThreadResourceResponseData structs are fully defined in common code as are the methods to copyData() and adopt(copiedData).

Awesome!

> WebCore/platform/network/ResourceRequestBase.h:143
> +        static bool compare(const ResourceRequest& a, const ResourceRequest& b);

When I see "compare", I think stpcmp and expect that 0 means equal. How about isSame or isEqual or equivalent, etc.? Ugh, I see ResourceResponse already has this. I still hate the name but consistency is good, so nevermind :(


Do this: omit "a" and "b" as they add no information. (Yes, ResourceResponseBase.h does the same thing but it is wrong and consistency here adds no value.)

> WebCore/platform/network/android/ResourceRequest.h:58
> +    void doPlatformAdopt(PassOwnPtr<CrossThreadResourceRequestData> data) { }

Omit data here or else you will get unused variable erros/warnings on some platforms (throughout).

> WebCore/platform/network/chromium/ResourceRequest.h:93
> +        PassOwnPtr<CrossThreadResourceRequestData> doPlatformCopyData(PassOwnPtr<CrossThreadResourceRequestData> data) const;

Omit param name "data" here as it adds no information.

> WebCore/platform/network/chromium/ResourceRequest.h:94
> +        void doPlatformAdopt(PassOwnPtr<CrossThreadResourceRequestData> data);

Ditto.

I guess that's not a merge conflict after all?
WebKitTools/Scripts/build-webkit fails

Looking...
