This is the first try to add private browsing support to soup in WK2. 

One problem with this patch is that it does not use the identifier base when creating a private browsing session. The Mac port uses the bundle name of the UIProcess. Similarly, we can use the process name of the UIProcess, but I am sure what to do with this identifier base in ResourceHandle::createPrivateBrowsingSession.

Any comment is welcome.

This should be kept under a PLATFORM(MAC) || USE(CFNETWORK) || USE(SOUP) check, since it's still not universally supported.

What do you mean handle identifierBase? What do you need to do with it?

There should be no empty line here.

Okay, I will fix the style issues. I intentionally violated the style issues as I tried to keep the original code as-is.

This method is not platform-specific. Isn't it okay to make other ports return false by initializing m_isPrivate to false in the constructor?

I will ask the original authors about the intention of identifierBase.

Okay. I will fix it.

Thanks for your review.

It's used by CFNetwork to identify named sessions (specifically, a private browsing session for Safari would be created with identifierBase "com.apple.Safari", and will be named "com.apple.Safari.PrivateBrowsing").

You probably don't need it unless Soup also identifies sessions by a string identifier.

Thanks for the information. I changed the patch to ignore the string identifier passed by createPrivateBrowsingSession() because Soup does not identify sessions by a string identifier.

It seems the last argument of g_object_set should NULL instead of 0. Otherwise, EFL build fails with the following errors:

Building CXX object Source/WebCore/CMakeFiles/WebCore.dir/platform/network/soup/ResourceHandleSoup.cpp.o

It seems we pass NULL to g_object_set in other places too. Should we add an exception to check-webkit-style?

Bug 32858 and Bug 39372 fixed this false positive style error. But the rule works only when the entire function call is one line. If g_*() function call spans multiple lines, check-webkit-style does not recognize the pattern.

I realized that this is not necessary because WebPreferences keeps track of privateBrowsingPageGroupCount and sends WebProcess::EnsurePrivateBrowsingSession and WebProcess::DestroyPrivateBrowsingSession messages accordingly.

I will fix the patch.
