bpo-40521: Make bytes singletons per interpreter (GH-21074)
Each interpreter now has its own empty bytes string and single byte
character singletons.

bpo-29882: Add _Py_popcount32() function (GH-20518)
* Rename pycore_byteswap.h to pycore_bitutils.h.
* Move popcount_digit() to pycore_bitutils.h as _Py_popcount32().
* _Py_popcount32() uses GCC and clang builtin function if available.
* Add unit tests to _Py_popcount32().

bpo-40792: Make the result of PyNumber_Index() always having exact type int. (GH-20443)
Previously, the result could have been an instance of a subclass of int.

Also revert bpo-26202 and make attributes start, stop and step of the range
object having exact type int.

Add private function _PyNumber_Index() which preserves the old behavior
of PyNumber_Index() for performance to use it in the conversion functions
like PyLong_AsLong().

bpo-40302: UTF-32 encoder SWAB4() macro use a|b rather than a+b (GH-19572) 2020-04-17 19:13:34 +02:00

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

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)
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-36051: Drop GIL during large bytes.join() (GH-17757)
Improve multi-threaded performance by dropping the GIL in the fast path

done if the output size exceeds a threshold.

bpo-33954: Fix _PyUnicode_InsertThousandsGrouping() (GH-10623)
Fix str.format(), float.__format__() and complex.__format__() methods
for non-ASCII decimal point when using the "n" formatter.

Changes:

* Rewrite _PyUnicode_InsertThousandsGrouping(): it now requires
  a _PyUnicodeWriter object for the buffer and a Python str object
  for digits.
* Rename FILL() macro to unicode_fill(), convert it to static inline function,
  add "assert(0 <= start);" and rework its code.

bpo-34523: Support surrogatepass in locale codecs (GH-8995)
Add support for the "surrogatepass" error handler in
PyUnicode_DecodeFSDefault() and PyUnicode_EncodeFSDefault()
for the UTF-8 encoding.

Changes:

* _Py_DecodeUTF8Ex() and _Py_EncodeUTF8Ex() now support the
  surrogatepass error handler (_Py_ERROR_SURROGATEPASS).
* _Py_DecodeLocaleEx() and _Py_EncodeLocaleEx() now use
  the _Py_error_handler enum instead of "int surrogateescape" to pass
  the error handler. These functions now return -3 if the error
  handler is unknown.
* Add unit tests on _Py_DecodeLocaleEx() and _Py_EncodeLocaleEx()
  in test_codecs.
* Rename get_error_handler() to _Py_GetErrorHandler() and expose it
  as a private function.
* _freeze_importlib doesn't need config.filesystem_errors="strict"
  workaround anymore.

Siddhesh Poyarekar 55edd0c185 bpo-33012: Fix invalid function cast warnings with gcc 8 for METH_NOARGS. (GH-6030)
METH_NOARGS functions need only a single argument but they are cast
into a PyCFunction, which takes two arguments.  This triggers an
invalid function cast warning in gcc8 due to the argument mismatch.
Fix this by adding a dummy unused argument.
