Hi, I was excited to see official dtrace support for python 3.6.0 on OS X, but I have not been able to make it work:
1. I built my own python from sources on OS X 10.9, with the --with-dtrace support 2. if I launch `python3.6 -q &` and then `sudo dtrace -l -P python$!`, I get the following output: ID PROVIDER MODULE FUNCTION NAME 2774 python48084 python3.6 _PyEval_EvalFrameDefault function-entry 2775 python48084 python3.6 _PyEval_EvalFrameDefault function-return 2776 python48084 python3.6 collect gc-done 2777 python48084 python3.6 collect gc-start 2778 python48084 python3.6 _PyEval_EvalFrameDefault line Which looks similar but not the same as the example given in the doc at https://docs.python.org/dev/howto/instrumentation.html#enabling-the-static-markers 3. When I try to test anything with the given call_stack.d example, I can't make it work at all: """ # script.py def start(): foo() def foo(): pass start() """ I am not very familiar with dtrace, so maybe I a missing a step, there is a documentation bug, or it depends on which OS X version you are using ? Thanks, David
