This won't build on El Capitan without internal headers.  You need a change like this to CFNetworkSPI.h:

Also, this needs to include a PLATFORM(MAC) check to fix the build failure on iOS:

/Volumes/Data/EWS/WebKit/Source/WebCore/platform/network/mac/CookieJarMac.mm:123:5: error: '__MAC_OS_X_VERSION_MIN_REQUIRED' is not defined, evaluates to 0 [-Werror,-Wundef]
#if __MAC_OS_X_VERSION_MIN_REQUIRED >= 101100
    ^
1 error generated.

#if PLATFORM(MAC) && __MAC_OS_X_VERSION_MIN_REQUIRED >= 101100

Yup, we already went over this in the radar. Needs the forward declare, but this one isn't quite right.

This is sad and always catches me by surprise - iOS uses both cookiejarmac and cookiejarcf  :(

Actually, this is SUPREMELY surprising.  How is this possible?  iOS gets this exact same symbol twice - Once from CookieJarMac and once from CookieJarCFNet, yet it uses the CFNet version  o_O

This adds the PLATFORM(MAC), but it's weird that it's needed.

We need an answer to why that builds on iOS, and how it's possible that iOS gets the same symbol twice and chooses the right one.  =/

r=me with the macro fixes.

This still needs to be changed to prevent an iOS build failure:

#if PLATFORM(MAC) && __MAC_OS_X_VERSION_MIN_REQUIRED >= 101100

Apparently this file is compiled on iOS but not used.

> Source/WebCore/platform/spi/cf/CFNetworkSPI.h:132
> +#if PLATFORM(MAC) && __MAC_OS_X_VERSION_MIN_REQUIRED >= 101100

This should really be:

#if !USE(APPLE_INTERNAL_SDK) || PLATFORM(MAC) && __MAC_OS_X_VERSION_MIN_REQUIRED >= 101100

r=me but consider the macro change.

This should probably be:

#if !USE(APPLE_INTERNAL_SDK) || PLATFORM(MAC) && __MAC_OS_X_VERSION_MIN_REQUIRED >= 101100

I know why.  It's because the EWS builder has the NSURLConnection path defined (so WTF_USE_CFNETWORK set to 0), while builds against an internal iOS SDK have WTF_USE_CFNETOWRK set to 1.  (This needs to be fixed; I'll explain the details in radar.)

Otherwise there would be linker errors with duplicate symbols.

Comment withdrawn after taking to Brady in person.  The !USE(APPLE_INTERNAL_SDK) doesn't matter here.

[Brady Eidson]

Since EWS ran and since I was actually back at my computer, landed myself instead of waiting on the CQ.

Why no tests?
