Backed out changeset b9c9691c72c5
...
Issue #28858 : The change b9c9691c72c5 introduced a regression. It seems like
_PyObject_CallArg1() uses more stack memory than
PyObject_CallFunctionObjArgs().
2016-12-04 22:59:09 +01:00
27580c1fb5
Replace PyObject_CallFunctionObjArgs() with fastcall
...
* 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 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.

Issue #21233 : Add new C functions: PyMem_RawCalloc(), PyMem_Calloc(),
...
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.
...
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.

Issue #4688 : Add a heuristic so that tuples and dicts containing only
untrackable objects are not tracked by the garbage collector. This can
reduce the size of collections and therefore the garbage collection overhead
on long-running programs, depending on their particular use of datatypes.

Shootout 40% faster)
