* bpo-46906: Add PyFloat_Pack8() to the C API (GH-31657)Victor Stinner2022-03-111-5/+4
| | | | | | | | | | | | | | | | | | | | | | Add new functions to pack and unpack C double (serialize and deserialize): * PyFloat_Pack2(), PyFloat_Pack4(), PyFloat_Pack8() * PyFloat_Unpack2(), PyFloat_Unpack4(), PyFloat_Unpack8() Document these functions and add unit tests. Rename private functions and move them from the internal C API to the public C API: * _PyFloat_Pack2() => PyFloat_Pack2() * _PyFloat_Pack4() => PyFloat_Pack4() * _PyFloat_Pack8() => PyFloat_Pack8() * _PyFloat_Unpack2() => PyFloat_Unpack2() * _PyFloat_Unpack4() => PyFloat_Unpack4() * _PyFloat_Unpack8() => PyFloat_Unpack8() Replace the "unsigned char*" type with "char*" which is more common and easy to use.

* bpo-40059: Add tomllib (PEP-680) (GH-31498)Taneli Hukkinen2022-03-081-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This adds a new standard library module, `tomllib`, for parsing TOML. The implementation is based on Tomli (https://github.com/hukkin/tomli). ## Steps taken (converting `tomli` to `tomllib`) - Move everything in `tomli:src/tomli` to `Lib/tomllib`. Exclude `py.typed`. - Remove `__version__ = ...` line from `Lib/tomllib/__init__.py` - Move everything in `tomli:tests` to `Lib/test/test_tomllib`. Exclude the following test data dirs recursively: - `tomli:tests/data/invalid/_external/` - `tomli:tests/data/valid/_external/` - Create `Lib/test/test_tomllib/__main__.py`: ```python import unittest from . import load_tests unittest.main() ``` - Add the following to `Lib/test/test_tomllib/__init__.py`: ```python import os from test.support import load_package_tests def load_tests(*args): return load_package_tests(os.path.dirname(__file__), *args) ``` Also change `import tomli as tomllib` to `import tomllib`. - In `cpython/Lib/tomllib/_parser.py` replace `__fp` with `fp` and `__s` with `s`. Add the `/` to `load` and `loads` function signatures. - Run `make regen-stdlib-module-names` - Create `Doc/library/tomllib.rst` and reference it in `Doc/library/fileformats.rst`
* bpo-46841: Use inline caching for calls (GH-31709)Brandt Bucher2022-03-074-355/+191

* bpo-46940: Don't override existing AttributeError suggestion information ↵Pablo Galindo Salgado2022-03-071-3/+6
| | | | | | | | | | | | (GH-31710) When an exception is created in a nested call to PyObject_GetAttr, any external calls will override the context information of the AttributeError that we have already placed in the most internal call. This will cause the suggestions we create to nor work properly as the attribute name and object that we will be using are the incorrect ones. To avoid this, we need to check first if these attributes are already set and bail out if that's the case.

* bpo-45431: Rename CFrame to _PyCFrame in the C API (GH-31584)Victor Stinner2022-02-281-3/+3
| | | | | | Rename also struct _cframe to struct _PyCFrame. Add a comment suggesting using public functions rather than using directly the private _PyCFrame structure.

* bpo-46816: Remove declarations for non-__STDC__ compilers (GH-31466)Oleg Iarygin2022-02-251-6/+0
| | | | After Python switched to C11, there is a guarantee that every compiler conforms to ISO C so checks of __STDC__ have no sense.
* bpo-46836: Rename InterpreterFrame to _PyInterpreterFrame (GH-31583)Victor Stinner2022-02-255-59/+59
| | | | | Rename also struct _interpreter_frame to struct _PyInterpreterFrame. Reduce risk of name conflicts if a project includes pycore_frame.h.
* bpo-45316: Move _PyArg_Fini() to internal C API (GH-31580)Victor Stinner2022-02-252-1/+2
| | | | Move the private unexported _PyArg_Fini() function to the internal C API: to the pycore_pylifecycle.h header file.
* bpo-45316: Move private functions to internal C API (GH-31579)Victor Stinner2022-02-251-1/+2

* bpo-46748: Don't import <stdbool.h> in public headers (GH-31553)Petr Viktorin2022-02-251-0/+2
| | | | | | | <stdbool.h> is the standard/modern way to define embedd/extends Python free to define bool, true and false, but there are existing applications that use slightly different redefinitions, which fail if the header is included. It's OK to use stdbool outside the public headers, though. https://bugs.python.org/issue46748
* bpo-46656: Remove Py_NO_NAN macro (GH-31160)Victor Stinner2022-02-251-2/+0
| | | | Building Python now requires support for floating point Not-a-Number (NaN): remove the Py_NO_NAN macro.

| | | | Thanks to the new pytypedefs.h, it becomes to use type names like PyObject rather like structure names like "struct _object".

* bpo-45412: Add _PY_SHORT_FLOAT_REPR macro (GH-31171)Victor Stinner2022-02-233-12/+13
| | | | | | | | | | Remove the HAVE_PY_SET_53BIT_PRECISION macro (moved to the internal C API). * Move HAVE_PY_SET_53BIT_PRECISION macro to pycore_pymath.h. * Replace PY_NO_SHORT_FLOAT_REPR macro with _PY_SHORT_FLOAT_REPR macro which is always defined. gcc -Wundef emits a warning when using _PY_SHORT_FLOAT_REPR but the macro is not defined, if pycore_pymath.h include was forgotten.

* bpo-46541: Discover the global strings. (gh-31346)Eric Snow2022-02-154-2/+13
| | | | | | | Instead of manually enumerating the global strings in generate_global_objects.py, we extrapolate the list from usage of _Py_ID() and _Py_STR() in the source files. This is partly inspired by gh-31261. https://bugs.python.org/issue46541
