r=me, but the enum/bit combo is a bit ugly, the bitifield use here is sloppy and there is some incorrectly formatted code
> WebCore/storage/DatabaseAuthorizer.h:97
> + void setPermissions(int permissions);
It doesn’t seem right to use int for permissions, but use an enum for the values. I think we normally have a better idiom for this sort of thing.
> WebCore/storage/DatabaseAuthorizer.h:114
> + int m_permissions;
> bool m_securityEnabled : 1;
All these bools are set to be a single bit to save memory, I suppose, and then the three bit permissions is taking up an entire 32-bit int! I think the use of bitfields on the bools is excessive. You could use a bitfield for permissions, but because we are using a signed type, int, we’d need to use four bits. It would be better to use unsigned and three bits. Or not use bitfields at all in this class.

This is not indented correctly.
