* bpo-30860: Consolidate stateful runtime globals. (#3397)Eric Snow2017-09-081-213/+98
| | | | | | | * group the (stateful) runtime globals into various topical structs * consolidate the topical structs under a single top-level _PyRuntimeState struct * add a check-c-globals.py script that helps identify runtime globals Other globals are excluded (see globals.txt and check-c-globals.py).

* Backed out changeset b9c9691c72c5Victor Stinner2016-12-041-1/+1
| | | | | | Issue #28858: The change b9c9691c72c5 introduced a regression. It seems like _PyObject_CallArg1() uses more stack memory than PyObject_CallFunctionObjArgs().
* Replace PyObject_CallFunctionObjArgs() with fastcallVictor Stinner2016-12-011-1/+1
| | | | | | | | | | | | | | * PyObject_CallFunctionObjArgs(func, NULL) => _PyObject_CallNoArg(func) * PyObject_CallFunctionObjArgs(func, arg, NULL) => _PyObject_CallArg1(func, arg) PyObject_CallFunctionObjArgs() allocates 40 bytes on the C stack and requires extra work to "parse" C arguments to build a C array of PyObject*. _PyObject_CallNoArg() and _PyObject_CallArg1() are simpler and don't allocate memory on the C stack. This change is part of the fastcall project. The change on listsort() is related to the issue #23507.

* 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.

|/ | | | | | PyObject_Calloc(), _PyObject_GC_Calloc(). bytes(int) and bytearray(int) are now using ``calloc()`` instead of ``malloc()`` for large objects which is faster and use less memory (until the bytearray buffer is filled with data).

* | 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.
