bpo-32255: Always quote a single empty field when write into a CSV file. (#4769)

2017-12-12T09:57:06+00:00

This allows to distinguish an empty row from a row consisting of a single empty field.

Use NULL rather than 0. (#778)

2017-03-23T15:53:47+00:00

There was few cases of using literal 0 instead of NULL in the context of
pointers.  While this was a legitimate C code, using NULL rather than 0 makes
the code clearer.

Issue #28999: Use Py_RETURN_NONE, Py_RETURN_TRUE and Py_RETURN_FALSE wherever

possible.  Patch is writen with Coccinelle.

Backed out changeset b9c9691c72c5

2016-12-04T21:59:09+00:00

Issue #28858: The change b9c9691c72c5 introduced a regression. It seems like
_PyObject_CallArg1() uses more stack memory than
PyObject_CallFunctionObjArgs().

Replace PyObject_CallFunctionObjArgs() with fastcall

2016-12-01T13:43:22+00:00

* 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.
