Bug 127554 – [GLIB] Add GUniqueOutPtr and use it instead of GOwnPtr

• Component: Web Template Framework
• Status: RESOLVED FIXED

[Carlos Garcia Campos]

In r162516 we added GUniquePtr that was used to replace GOwnPtr in all case except when the output pointer is needed. For those cases we can't use std::unique_ptr, so we need a class to cover these cases.

No need for calling reset() here -- the GUniqueOutPtr will handle freeing the memory when it goes out of scope and is destroyed.

No need for calling reset() here (since the unique pointer will be reset when outPtr() is called the next time) ...

> Tools/TestWebKitAPI/Tests/WebKit2Gtk/TestWebExtensions.cpp:168
> -    result.clear();
> +    result.reset();

... or here (since the pointer will be deleted when GUniqueOutPtr goes out of scope).

I guess GUniqueOutPtr is now smart enough that the user doesn't really have to know about the reset() method, so it can be made private.

Thanks for the review.

Well, this is actually a test to check that reset works, if we make it private we don't need this test.

You are right.

Yes, I agree, and the proof is that it's only used in this test and it's not actually needed
