* Don't run garbage collection on interpreter exit if it was explicitly disabledŁukasz Langa2016-09-101-0/+9
| | | | by the user.
* DTrace support: function calls, GC activity, line executionŁukasz Langa2016-09-101-0/+8
| | | | | | | | | | | | | | | | | | | 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.

* | whatsnew for gc.get_stats, plus doc tweaks.R David Murray2013-12-261-0/+1
| | | | | | | | | | | | | | | | | | | | Clarified the "At the moment" wording, and added the get_stats entry in the module summary that Serhiy noted was missing at the end of issue 16351. Given that pydoc lists all the function docstrings, I'm not sure that module summary section is actually needed; but, it is probably better to address that when the module is converted to use Argument Clinic. In the meantime we should keep the list complete.
