Christian Heimes	3d2b407da0	bpo-31574: importlib dtrace (#3749) ... Importlib was instrumented with two dtrace probes to profile import timing. Signed-off-by: Christian Heimes <christian@python.org>	2017-09-29 15:53:19 -07:00
Łukasz Langa	a785c87d6e	DTrace support: function calls, GC activity, line execution ... Tested on macOS 10.11 dtrace, Ubuntu 16.04 SystemTap, and libbcc. Largely based by an initial patch by Jesús Cea Avión, with some influence from Dave Malcolm's SystemTap patch and Nikhil Benesch's unification patch. Things deliberately left out for simplicity: - ustack helpers, I have no way of testing them at this point since they are Solaris-specific - PyFrameObject * in function__entry/function__return, this is SystemTap-specific - SPARC support - dynamic tracing - sys module dtrace facility introspection All of those might be added later.	2016-09-09 17:37:37 -07:00
