====== 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.
