DTrace Hangout 21 July 2016

We don't install the CDDL headers on FreeBSD but these are needed by the Python. Mark will put up a patch to address this.
Mark is looking at MFC'ing anonymous tracing to 10
George will expand all of the storage sizes in DTrace to more reasonable 2016 values. Mark suggests that we add these as sysctls.
Mark describes the current anonymous tracing stuff for Russ and Samuel who have an application for it.
Mark brings up the fix for predicates that has now gone into FreeBSD but is not fixed in other repos.
Turns out that there are no extensions actually added by Apple to DTrace.
We then discuss the fds support in OS/X. The implementation on OS/X only shows the last part of the path
There is some sort of binary format in the Apple open source code base.
Arun has added pretty printing of UUIDs by adding a %U to dtrace_printf(). The next steps are better support for UUIDs and scripting.
