RESOLVED FIXED 196268
Inhibit CFNetwork logging in private sessions

Summary Inhibit CFNetwork logging in private sessions
Keith Rollin
Reported 2019-03-26 13:27:16 PDT
Before performing any logging, the NetworkProcess checks to see if it's performing an operation associated with a private (ephemeral) browsing session. If so, it skips all logging. However, networking layers below the NetworkProcess don't know about private browsing, so they would still perform their own logging. CFNetwork now has a flag that lets us control that, so set it to False if private browsing.

Ugh. OK. So when should IOS vs. IOS_FAMILY be used? I was modeling my conditional on the one a few lines above: #if (PLATFORM(MAC) && __MAC_OS_X_VERSION_MIN_REQUIRED >= 101400) || (PLATFORM(IOS_FAMILY) && __IPHONE_OS_VERSION_MIN_REQUIRED >= 130000) #define HAVE_SANDBOX_ISSUE_MACH_EXTENSION_TO_PROCESS_BY_PID 1 #endif

That logging is priceless in tracking down networking issues. Why do you think it should be removed unconditionally?
