* gh-108444: Add PyLong_AsInt() public function (#108445)Victor Stinner2023-08-241-0/+6
| | | | | | * Rename _PyLong_AsInt() to PyLong_AsInt(). * Add documentation. * Add test. * For now, keep _PyLong_AsInt() as an alias to PyLong_AsInt().
* gh-87347: Add parenthesis around PyXXX_Check() arguments (#92815)Victor Stinner2022-06-161-1/+1

* bpo-45459: Add pytypedefs.h header file (GH-31527)Victor Stinner2022-02-241-2/+0
| | | | | | | | | | | | | | | | | | Move forward declarations of Python C API types to a new pytypedefs.h header file to solve interdependency issues between header files. pytypedefs.h contains forward declarations of the following types: * PyCodeObject * PyFrameObject * PyGetSetDef * PyInterpreterState * PyLongObject * PyMemberDef * PyMethodDef * PyModuleDef * PyObject * PyThreadState * PyTypeObject
* bpo-35134: Add Include/cpython/longobject.h (GH-29044)Victor Stinner2021-10-191-130/+3
| | | | | | | | | | Move Include/longobject.h non-limited API to a new Include/cpython/longobject.h header file. Move the following definitions to the internal C API: * _PyLong_DigitValue * _PyLong_FormatAdvancedWriter() * _PyLong_FormatWriter()
* bpo-42161: Remove private _PyLong_Zero and _PyLong_One (GH-23003)Victor Stinner2020-10-271-3/+0
| | | | | Use PyLong_FromLong(0) and PyLong_FromLong(1) of the public C API instead. For Python internals, _PyLong_GetZero() and _PyLong_GetOne() of pycore_long.h can be used.
* bpo-41123: Remove PyLong_FromUnicode() (GH-21204)Inada Naoki2020-06-291-2/+0

* bpo-37999: No longer use __int__ in implicit integer conversions. (GH-15636)Serhiy Storchaka2020-05-261-17/+0
| | | | Only __index__ should be used to make integer conversions lossless.

* Cut disused recode_encoding logic in _PyBytes_DecodeEscape. (GH-16013)Greg Price2019-09-121-1/+1
| | | | | | | | | | | | | | | | | | | | | All call sites pass NULL for `recode_encoding`, so this path is completely untested. That's been true since before Python 3.0. It adds significant complexity to this logic, so it's best to take it out. All call sites now have a literal NULL, and that's been true since commit 768921cf3 eliminated a conditional (`foo ? bar : NULL`) at the call site in Python/ast.c where we're parsing a bytes literal. But even before then, that condition `foo` had been a constant since unadorned string literals started meaning Unicode, in commit 572dbf8f1 aka v3.0a1~1035 . The `unicode` parameter is already unused, so mark it as unused too. The code that acted on it was also taken out before Python 3.0, in commit 8d30cc014 aka v3.0a1~1031 . The function (PyBytes_DecodeEscape) is exposed in the API, but it's never been documented.

| | | | | | | | | | | | | | * Don't overallocate by 400% when recode is needed: only overallocate on demand using _PyBytesWriter. * Use _PyLong_DigitValue to convert hexadecimal digit to int * Create _PyBytes_DecodeEscapeRecode() subfunction
* | Optimize bytes.fromhex() and bytearray.fromhex()Victor Stinner2015-10-141-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | Issue #25401: Optimize bytes.fromhex() and bytearray.fromhex(): they are now between 2x and 3.5x faster. Changes: * Use a fast-path working on a char* string for ASCII string * Use a slow-path for non-ASCII string * Replace slow hex_digit_to_int() function with a O(1) lookup in _PyLong_DigitValue precomputed table * Use _PyBytesWriter API to handle the buffer * Add unit tests to check the error position in error messages
* | Issue #25349: Optimize bytes % intVictor Stinner2015-10-091-0/+7
|/ | | | | | | | Optimize bytes.__mod__(args) for integere formats: %d (%i, %u), %o, %x and %X. _PyBytesWriter is now used to format directly the integer into the writer buffer, instead of using a temporary bytes object. Formatting is between 30% and 50% faster on a microbenchmark.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | and str.format(args) * Formatting string, int, float and complex use the _PyUnicodeWriter API. It avoids a temporary buffer in most cases. * Add _PyUnicodeWriter_WriteStr() to restore the PyAccu optimization: just keep a reference to the string if the output is only composed of one string * Disable overallocation when formatting the last argument of str%args and str.format(args) * Overallocation allocates at least 100 characters: add min_length attribute to the _PyUnicodeWriter structure * Add new private functions: _PyUnicode_FastCopyCharacters(), _PyUnicode_FastFill() and _PyUnicode_FromASCII() The speed up is around 20% in average.

The exponent produced by _PyLong_Frexp now has type Py_ssize_t instead of the previously used int, and no longer needs scaling by PyLong_SHIFT. This frees the math module from having to know anything about the PyLong implementation. This closes issue #5576. ........
