Is this one right? It's not a Copy or Create.

Same question.

I think this might read cleaner without the retain and adoption.

This should use alloc / initWithDouble:

> -        value.adoptNS([[NSNumber numberWithDouble:amount] retain]);
> +        value = adoptNS([[NSNumber numberWithDouble:amount] retain]);

This should use alloc / initWithDouble:

> +        value = adoptNS([[NSNumber numberWithDouble:amount] retain]);

This should use alloc / initWithDouble:

> -        value.adoptNS([[NSNumber numberWithDouble:amount] retain]);
> +        value = adoptNS([[NSNumber numberWithDouble:amount] retain]);

This should use alloc / initWithDouble:

> -        value.adoptNS([[NSNumber numberWithDouble:amount] retain]);
> +        value = adoptNS([[NSNumber numberWithDouble:amount] retain]);

This should use alloc / initWithDouble:

> Source/WebCore/platform/graphics/cg/GraphicsContext3DCG.cpp:357
> -        bitmapContext.adoptCF(CGBitmapContextCreate(0, m_imageWidth, m_imageHeight, 8, m_imageWidth * 4,

We should de-indent this stuff.

We should probably double check this is supposed to be adopted. It doesn't adhere to naming rules.

Same note as above.

We could remove the adopt / retain.

> -        m_path.adoptNS([[NSString stringWithUTF8String:temporaryFileName] retain]);

This should use alloc / initWithUTF8String:

> Source/WebKit2/Shared/mac/ArgumentCodersMac.mm:280
> -    result.adoptCF(resultString.leakRef());
> +    result = adoptCF(resultString.leakRef());

I think this should probably be adoptNS.

adoptNS?

adoptNS?

I’m not going to make these changes since I don’t want to combine bug fixes and handwritten tweaks with a style change that is a global replace, but I do think you spotted some bugs and opportunities for improvement that I will tackle.

Might be wrong. If so, not newly wrong. Need to read CGImageSourceCopyTypeIdentifiers documentation to be sure.

It definitely would.

I wonder if it could just use @ syntax instead.

There was an earlier version of this patch where I did these changes by hand instead of with a global replace. In that one, I had de-indented this.

I think it should just be a straight assignment or a call to a RetainPtr release function rather than an adoptCF/leakRef pair. Same applies to all the other cases like this in this file.

I double checked. It is supposed to be adopted.

Though bugzilla doesn't show it, these comments were originally accompanied by and r+. I was just using the opportunity of reviewing that much code to look for past mistakes we could fix, but I certainly agree they shouldn't happen at the same time.  Thanks for making this big change!

Oh, duh, yeah.
