> Source/WebKit/ChangeLog:8

as follows:

caches (plural) vs is (singular)

> Source/WebKit/ChangeLog:10

caches (plural) vs is (singular)

> Source/WebCore/page/SecurityOriginData.h:70

There is already an operator==() on this class.

Can .get(). be replace by -> ?

We usually omit the const.

We usually omit the const.

Seems inefficient to Stringify just to compare. Assuming recordOrigin is a SecurityOriginData, we could do:
SecurityOriginData::fromSecurityOrigin(origin) == recordOrigin.

Also, we could cache SecurityOriginData::fromSecurityOrigin(origin) before the loops.

Youenn, please stop adding C SPI without corresponding ObjC SPI.  It takes my project a step in the wrong direction.
Chris, please r- any patches that add C SPI without adding corresponding ObjC SPI.

There is no plan to make use of this SPI outside WebKitTestRunner.
I do not plan to add a corresponding ObjC SPI.
Maybe we can move it elsewhere to ensure it never gets used outside WebKitTestRunner.
