Jer Noble gave the following feedback in Slack:

This logging change looks pretty bad; there’s no need to use printf(); DEBUG_LOG() works with StringConcatenation. There’s no need to include the method name, because that’s included with LOGIDENTIFIER. And *this shouldn’t be needed here as that’s also included in LOGIDENTIFIER*.

Can you please undo these changes you made? They can be replaced with something more like this:

DEBUG_LOG(LOGIDENTIFIER, "size = ", size, ", buffered = ", m_private->buffered()->ranges());

If you get an error concatenating a PlatformTimeRanges, the right way to deal with that is to add a macro to PlatformTimeRanges.h like the one from MediaTime.h:

template<typename> struct LogArgument;

template<> struct LogArgument<MediaTime> {
    static String toString(const MediaTime& time) { return time.toJSONString(); }
};
template<> struct LogArgument<MediaTimeRange> {
    static String toString(const MediaTimeRange& range) { return range.toJSONString(); }
};
