_json.c: use Py_UNUSED() macro (GH-17053)

2019-11-05T10:44:28+00:00

Remove UNUSED macro: use Py_UNUSED() macro instead.

bpo-37587: json: Use _PyUnicodeWriter when scanning string. (GH-15591)

2019-10-17T07:12:41+00:00

bpo-37587: optimize json.loads (GH-15134)

2019-08-08T08:57:10+00:00

Use a tighter scope temporary variable to help register allocation.
1% speedup for large string.

Use PyDict_SetItemDefault() for memoizing keys.
At most 4% speedup when the cache hit ratio is low.

bpo-37587: Make json.loads faster for long strings (GH-14752)

2019-07-30T14:16:34+00:00

When scanning the string, most characters are valid, so
checking for invalid characters first means never needing
to check the value of strict on valid strings, and only
needing to check it on invalid characters when doing
non-strict parsing of invalid strings.

This provides a measurable reduction in per-character
processing time (~11% in the pre-merge patch testing).

bpo-37483: add _PyObject_CallOneArg() function (#14558)

2019-07-04T10:31:34+00:00

bpo-36974: tp_print -> tp_vectorcall_offset and tp_reserved -> tp_as_async (GH-13464)

2019-05-31T02:13:39+00:00

Automatically replace
tp_print -> tp_vectorcall_offset
tp_compare -> tp_as_async
tp_reserved -> tp_as_async

bpo-36793: Remove unneeded str definitions. (GH-13081)

2019-05-06T19:29:40+00:00

Classes that define __str__ the same as __repr__ can
just inherit it from object.

bpo-36635: Change pyport.h for Py_BUILD_CORE_MODULE define (GH-12853)

2019-04-17T21:02:26+00:00

Change PyAPI_FUNC(type), PyAPI_DATA(type) and PyMODINIT_FUNC macros
of pyport.h when Py_BUILD_CORE_MODULE is defined.

The Py_BUILD_CORE_MODULE define must be now be used to build a C
extension as a dynamic library accessing Python internals: export the
PyInit_xxx() function in DLL exports on Windows.

Changes:

* Py_BUILD_CORE_BUILTIN and Py_BUILD_CORE_MODULE now imply
  Py_BUILD_CORE directy in pyport.h.
* ceval.c compilation now fails with an error if Py_BUILD_CORE is not
  defined, just to ensure that Python is build with the correct
  defines.
* setup.py now compiles _pickle.c with Py_BUILD_CORE_MODULE define.
* setup.py compiles _json.c with Py_BUILD_CORE_MODULE define, rather
  than Py_BUILD_CORE_BUILTIN define
* PCbuild/pythoncore.vcxproj: Add Py_BUILD_CORE_BUILTIN define.

bpo-35459: Use PyDict_GetItemWithError() instead of PyDict_GetItem(). (GH-11112)

2019-02-25T15:59:46+00:00

bpo-35081: Move accu.h to Include/internal/pycore_accu.h (GH-10271)

2018-11-01T01:30:36+00:00

The accu.h header is no longer part of the Python C API: it has been
moved to the "internal" headers which are restricted to Python
itself.

Replace #include "accu.h" with #include "pycore_accu.h".
