* gh-116322: Enable the GIL while loading C extension modules (#118560)Brett Simmers2024-05-071-3/+9
| | | | | | | | | | Add the ability to enable/disable the GIL at runtime, and use that in the C module loading code. We can't know before running a module init function if it supports free-threading, so the GIL is temporarily enabled before doing so. If the module declares support for running without the GIL, the GIL is later disabled. Otherwise, the GIL is permanently enabled, and will never be disabled again for the life of the current interpreter.

* gh-116322: Add Py_mod_gil module slot (#116882)Brett Simmers2024-05-034-4/+8
| | | | | | | | | | | | | | 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).

| | | | | | | | | | | | Add Py_GetConstant() and Py_GetConstantBorrowed() functions. In the limited C API version 3.13, getting Py_None, Py_False, Py_True, Py_Ellipsis and Py_NotImplemented singletons is now implemented as function calls at the stable ABI level to hide implementation details. Getting these constants still return borrowed references. Add _testlimitedcapi/object.c and test_capi/test_object.py to test Py_GetConstant() and Py_GetConstantBorrowed() functions.

| | | | | | | | Add PyUnicode_AsUTF8() function to the limited C API. multiprocessing posixshmem now uses PyUnicode_AsUTF8() instead of PyUnicode_AsUTF8AndSize(): the extension is built with the limited C API.

Replace _PyArg_UnpackStack() with PyArg_ParseTuple(). * _testcapi: add PYTESTCAPI_NEED_INTERNAL_API macro which is defined by _testcapi sub-modules which need the internal C API (pycore_modsupport.h): exceptions.c, float.c, vectorcall.c, watchers.c. * Remove Include/cpython/modsupport.h header file. Include/modsupport.h no longer includes the removed header file. * Fix mypy clinic.py
* gh-85283: Add PyMem_RawMalloc() to the limited C API (#108570)Victor Stinner2023-10-171-0/+4
| | | | | | | | | Add PyMem_RawMalloc(), PyMem_RawCalloc(), PyMem_RawRealloc() and PyMem_RawFree() to the limited C API. These functions were added by Python 3.4 and are needed to port stdlib extensions to the limited C API, like grp and pwd. Co-authored-by: Erlend E. Aasland <erlend@python.org>

* gh-110014: Remove PY_TIMEOUT_MAX from limited C API (#110217)Victor Stinner2023-10-021-1/+0
| | | | | | | | If the timeout is greater than PY_TIMEOUT_MAX, PyThread_acquire_lock_timed() uses a timeout of PY_TIMEOUT_MAX microseconds, which is around 280.6 years. This case is unlikely and limiting a timeout to 280.6 years sounds like a reasonable trade-off. The constant PY_TIMEOUT_MAX is not used in PyPI top 5,000 projects.
