Bug 58353 – Set minimum priority for fast lane connections

• Component: Platform
• Status: RESOLVED FIXED

[Pratik Solanki]

We should tell CFNetwork to allow images to use the reserved fast lane connections.

[Pratik Solanki]

eh.. allow scripts, not images.

+        * wtf/Platform.h: Define BUILDING_ON_IOS.

This is strange. When is one expected to use this?

As I just found out:

TARGET_OS_IPHONE is set to "1" for both iOS hardware and iOS Simulator builds, so just checking that would be sufficient.  We don't need to check for TARGET_OS_EMBEDDED or TARGET_IPHONE_SIMULATOR here.

If you want to clean up the definition for WTF_PLATFORM_IOS and WTF_PLATFORM_IOS_SIMULATOR below at the same time, that would be great, but not necessary.

WTF_PLATFORM_IOS only needs to check for TARGET_OS_IPHONE being 1, and WTF_PLATFORM_IOS_SIMULATOR only needs to check for TARGET_IPHONE_SIMULATOR being 1.

This could be used with other BUILDING_ON_MACOSX_KITTY macros, or would it be better to use PLATFORM(IOS) there instead since the BUILDING_ON_FOO macros are only for checking versions?

Since iOS isn't self-hosting, "BUILDING_ON_IOS" doesn't make much sense here.  Probably best to just use the existing PLATFORM(IOS) instead.
