Bug 48192 – [Cairo] Remove PlatformRefPtrCairo

• Component: Layout and Rendering
• Status: RESOLVED FIXED

[Martin Robinson]

PlatformRefPtrCairo is unecessary. It should be replaced by a RefPtr specialization. See this mailing list thread for more details: http://comments.gmane.org/gmane.os.opendarwin.webkit.devel/14529 This is the first step toward removing PlatformRefPtr entirely.

Remove PlatformRefPtrCairo

[Brent Fulgham]

I heartily approve of this change.  This should also resolve some of Darin's concerns about the use of the term 'Platform' in the RefPtr name.

Let's get it approved and landed!

Patch also including RefPtrCair.cpp and RefPtrCairo.h

My previous patch did not include RefPtrCairo.h and RefPtrCairo.cpp. I could not convince webkit-patch to include them for some reason, so I've had to roll the patch by hand.

If any of these errors are false positives, please file a bug against check-webkit-style.

I believe these are all false positives. When making the patch I discovered that LIKELY will not accept a pointer as an argument. It requires something which evaluates to a boolean.
