bpo-40302: UTF-32 encoder SWAB4() macro use a|b rather than a+b (GH-19572)

bpo-40302: Add pycore_byteswap.h header file (GH-19552)

2020-04-17T15:47:20+00:00

Add a new internal pycore_byteswap.h header file with the following
functions:

* _Py_bswap16()
* _Py_bswap32()
* _Py_bswap64()

Use these functions in _ctypes, sha256 and sha512 modules,
and also use in the UTF-32 encoder.

sha256, sha512 and _ctypes modules are now built with the internal
C API.

bpo-39087: Optimize PyUnicode_AsUTF8AndSize() (GH-18327)

2020-02-27T04:48:59+00:00

Avoid using temporary bytes object.

bpo-35081: Move bytes_methods.h to the internal C API (GH-18492)

2020-02-12T21:32:34+00:00

Move the bytes_methods.h header file to the internal C API as
pycore_bytes_methods.h: it only contains private symbols (prefixed by
"_Py"), except of the PyDoc_STRVAR_shared() macro.

closes bpo-39605: Fix some casts to not cast away const. (GH-18453)

2020-02-12T02:28:35+00:00

gcc -Wcast-qual turns up a number of instances of casting away constness of pointers. Some of these can be safely modified, by either:

Adding the const to the type cast, as in:

-    return _PyUnicode_FromUCS1((unsigned char*)s, size);
+    return _PyUnicode_FromUCS1((const unsigned char*)s, size);

or, Removing the cast entirely, because it's not necessary (but probably was at one time), as in:

-    PyDTrace_FUNCTION_ENTRY((char *)filename, (char *)funcname, lineno);
+    PyDTrace_FUNCTION_ENTRY(filename, funcname, lineno);

These changes will not change code, but they will make it much easier to check for errors in consts

bpo-39573: Use Py_SET_SIZE() function (GH-18402)

2020-02-07T22:18:08+00:00

Replace direct acccess to PyVarObject.ob_size with usage of
the Py_SET_SIZE() function.
