* gh-116322: Add Py_mod_gil module slot (#116882)Brett Simmers2024-05-031-0/+1
| | | | | | | | | | | | | | This PR adds the ability to enable the GIL if it was disabled at interpreter startup, and modifies the multi-phase module initialization path to enable the GIL when loading a module, unless that module's spec includes a slot indicating it can run safely without the GIL. PEP 703 called the constant for the slot `Py_mod_gil_not_used`; I went with `Py_MOD_GIL_NOT_USED` for consistency with gh-104148. A warning will be issued up to once per interpreter for the first GIL-using module that is loaded. If `-v` is given, a shorter message will be printed to stderr every time a GIL-using module is loaded (including the first one that issues a warning).
* gh-86493: Fix possible leaks in some modules initialization (GH-106768)Serhiy Storchaka2023-07-181-8/+7
| | | | Fix _ssl, _stat, _testinternalcapi, _threadmodule, cmath, math, posix, time.
* gh-106320: Add pycore_complexobject.h header file (#106339)Victor Stinner2023-07-021-0/+1
| | | | | | Add internal pycore_complexobject.h header file. Move _Py_c_xxx() functions and _PyComplex_FormatAdvancedWriter() function to this new header file.
* gh-104263: Rely on Py_NAN and introduce Py_INFINITY (GH-104202)Sebastian Berg2023-05-101-55/+6
| | | | | | | | | | This PR removes `_Py_dg_stdnan` and `_Py_dg_infinity` in favour of using the standard `NAN` and `INFINITY` macros provided by C99. This change has the side-effect of fixing a bug on MIPS where the hard-coded value used by `_Py_dg_stdnan` gave a signalling NaN rather than a quiet NaN. --------- Co-authored-by: Mark Dickinson <dickinsm@gmail.com>
* gh-99113: Add Py_MOD_PER_INTERPRETER_GIL_SUPPORTED (gh-104205)Eric Snow2023-05-051-0/+1
| | | Here we are doing no more than adding the value for Py_mod_multiple_interpreters and using it for stdlib modules. We will start checking for it in gh-104206 (once PyInterpreterState.ceval.own_gil is added in gh-104204).
* Few coverage nitpicks for the cmath module (#102067)Sergey B Kirpichev2023-02-221-2/+2
| | | | | | | | | | | - partial tests for cosh/sinh overflows (L535 and L771). I doubt both ||-ed conditions could be tested. - removed inaccessible case in sqrt (L832): ax=ay=0 is handled above (L823) because fabs() is exact. Also added test (checked with mpmath and gmpy2) for second condition on that line. - some trivial tests for isclose (cover all conditions on L1217-1218) - add comment for uncovered L1018 Co-authored-by: Mark Dickinson <dickinsm@gmail.com>

* bpo-46656: Remove Py_NO_NAN macro (GH-31160)Victor Stinner2022-02-251-2/+2
| | | | Building Python now requires support for floating point Not-a-Number (NaN): remove the Py_NO_NAN macro.
* bpo-45412: Add _PY_SHORT_FLOAT_REPR macro (GH-31171)Victor Stinner2022-02-231-7/+8
| | | | | | | | | | 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-45548: Remove _math.c workarounds for pre-C99 libm (GH-29179)Christian Heimes2021-10-251-4/+6
| | | | | | | | | | | | | The :mod:`math` and :mod:`cmath` implementation now require a C99 compatible ``libm`` and no longer ship with workarounds for missing acosh, asinh, expm1, and log1p functions. The changeset also removes ``_math.c`` and moves the last remaining workaround into ``_math.h``. This simplifies static builds with ``Modules/Setup`` and resolves symbol conflicts.

* bpo-43974: Move Py_BUILD_CORE_MODULE into module code (GH-29157)Christian Heimes2021-10-221-0/+4
| | | | | | | | | | | | | | setup.py no longer defines Py_BUILD_CORE_MODULE. Instead every module defines the macro before #include "Python.h" unless Py_BUILD_CORE_BUILTIN is already defined. Py_BUILD_CORE_BUILTIN is defined for every module that is built by Modules/Setup. The PR also simplifies Modules/Setup. Makefile and makesetup already define Py_BUILD_CORE_BUILTIN and include Modules/internal for us. Signed-off-by: Christian Heimes <christian@python.org>

* bpo-35081: Move dtoa.h header to the internal C API (GH-18489)Victor Stinner2020-02-121-0/+1
| | | | | | | Move the dtoa.h header file to the internal C API as pycore_dtoa.h: it only contains private functions (prefixed by "_Py"). The math and cmath modules must now be compiled with the Py_BUILD_CORE macro defined.
* bpo-38835: Don't use PyFPE_START_PROTECT and PyFPE_END_PROTECT (GH-17231)Victor Stinner2019-11-201-11/+2
| | | | | The PyFPE_START_PROTECT() and PyFPE_END_PROTECT() macros are empty: they have been doing nothing for the last year (since commit 735ae8d139a673b30b321dc10acfd3d14f0d633b), so stop using them.
* bpo-37206: Unrepresentable default values no longer represented as None. ↵Serhiy Storchaka2019-09-141-4/+4
| | | | | | | (GH-13933) In ArgumentClinic, value "NULL" should now be used only for unrepresentable default values (like in the optional third parameter of getattr). "None" should be used if None is accepted as argument and passing None has the same effect as not passing the argument at all.

The patch is collaborated work of Mark Dickinson and me. It was mostly done a few months ago. The patch fixes a lot of loose ends and edge cases related to operations with NaN, INF, very small values and complex math. The patch also adds acosh, asinh, atanh, log1p and copysign to all platforms. Finally it fixes differences between platforms like different results or exceptions for edge cases. Have fun :) ........ r62382 | christian.heimes | 2008-04-19 01:40:40 +0200 (Sat, 19 Apr 2008) | 2 lines Added new files to Windows project files More Windows related fixes are coming soon ........ r62383 | christian.heimes | 2008-04-19 01:49:11 +0200 (Sat, 19 Apr 2008) | 1 line Stupid me.
