Please do not nest #if statements like this. Put the exports into a separate section with this around the section:

#if ENABLE(VIDEO) && PLATFORM(IOS) && __IPHONE_OS_VERSION_MIN_REQUIRED >= 80000

I think if you run the sort-export-file script it will do that for you, in fact.

Why UNUSED_PARAM here?

And no UNUSED_PARAM here?

Not sure we need the PLATFORM(IOS) here at all, although I guess in a header file it’s nice to use it.

> Source/WebCore/platform/ios/WebVideoFullscreenInterfaceAVKit.mm:29
> -#if PLATFORM(IOS)
> +#if PLATFORM(IOS) && __IPHONE_OS_VERSION_MIN_REQUIRED >= 80000

Not sure we need the PLATFORM(IOS) here at all.

> Source/WebCore/platform/mac/HTMLConverter.mm:1570
> -#if PLATFORM(IOS) || __MAC_OS_X_VERSION_MIN_REQUIRED >= 1090

Not sure we need the PLATFORM(IOS) and PLATFORM(MAC) here at all. These get really long and hard to read so it would be nice to know if we need it or not.

> Source/WebCore/platform/network/cf/CookieJarCFNet.cpp:44
> +#if PLATFORM(WIN) || (PLATFORM(MAC) && __MAC_OS_X_VERSION_MIN_REQUIRED <= 1090) || (PLATFORM(IOS) && __IPHONE_OS_VERSION_MIN_REQUIRED < 80000)

Ditto.

> +#if (PLATFORM(IOS) && __IPHONE_OS_VERSION_MIN_REQUIRED >= 80000) || (PLATFORM(MAC) && __MAC_OS_X_VERSION_MIN_REQUIRED >= 10100)

Ditto.

Seems silly to check PLATFORM(IOS) in an iOS-specific source file.

> +#if (PLATFORM(IOS) && __IPHONE_OS_VERSION_MIN_REQUIRED >= 80000) || (PLATFORM(MAC) && __MAC_OS_X_VERSION_MIN_REQUIRED >= 1090)

Again, can we omit PLATFORM(IOS) and PLATFORM(MAC)?

> +#if (PLATFORM(IOS) && __IPHONE_OS_VERSION_MIN_REQUIRED >= 80000) || (PLATFORM(MAC) && __MAC_OS_X_VERSION_MIN_REQUIRED >= 1090)

Ditto.

Thanks for the review. I'll commit after making the changes.

Will fix.

I was getting a compiler warning since the mediaElement argument was not used.

>> +    return nullptr;

There is no argument for this method. Am I missing something?

Removed it.

We do need them. At least for iOS just having __MAC_OS_X_VERSION_MIN_REQUIRED will fail with an undefined macro warning. So we need PLATFORM(MAC) to guard against that. I think we would see similar failure for Mac if it ran into __IPHONE_OS_VERSION_MIN_REQUIRED. Hence the guard.

Removed it. The whole file is protected by PLATFORM(IOS) with a FIXME that says "Rename this file to LocalizedDataCacheIOS.mm and remove this guard." Guess we can do that in a separate bug.

Nope. Can't do this. Although the file is in iOS directory, it seems to be compiled on Mac as well.

Roll out in r165953, broke the build.

[Pratik Solanki]

Can't use PLATFORM(IOS) in header files. :( Need to use TARGET_OS_IPHONE. I'll fix and land again.
