* gh-116322: Rename PyModule_ExperimentalSetGIL to PyUnstable_Module_SetGIL ↵Petr Viktorin2024-05-061-1/+1

* gh-116322: Add Py_mod_gil module slot (#116882)Brett Simmers2024-05-031-1/+15
| | | | | | | | | | | | | | 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-117953: Split Up _PyImport_LoadDynamicModuleWithSpec() (gh-118203)Eric Snow2024-04-291-1/+1
| | | | | | | Basically, I've turned most of _PyImport_LoadDynamicModuleWithSpec() into two new functions (_PyImport_GetModInitFunc() and _PyImport_RunModInitFunc()) and moved the rest of it out into _imp_create_dynamic_impl(). There shouldn't be any changes in behavior. This change makes some future changes simpler. This is particularly relevant to potentially calling each module init function in the main interpreter first. Thus the critical part of the PR is the addition of _PyImport_RunModInitFunc(), which is strictly focused on running the init func and validating the result. A later PR will take it a step farther by capturing error information rather than raising exceptions. FWIW, this change also helps readers by clarifying a bit more about what happens when an extension/builtin module is imported.
* gh-111698: Restrict Py_mod_multiple_interpreters to 3.12+ Under ↵Eric Snow2023-11-061-1/+3
| | | | | | | Py_LIMITED_API (gh-111707) This should have been done in gh-104148. (A similar fix has already be done for that slot's value macros, and backported to 3.12. See gh-110968.)
* gh-110968: Py_MOD_PER_INTERPRETER_GIL_SUPPORTED was added to 3.12 (#111584)Victor Stinner2023-11-011-4/+4

* gh-110968: Py_MOD_PER_INTERPRETER_GIL_SUPPORTED new in 3.13. (#110969)Victor Stinner2023-10-171-2/+4
| | | | | | | | | | * Only add Py_MOD_PER_INTERPRETER_GIL_SUPPORTED to limited C API version 3.13. * errno, xxlimited and _ctypes_test extensions now need the limited C API version 3.13 to get Py_MOD_PER_INTERPRETER_GIL_SUPPORTED. They now include standard header files explicitly: <errno.h>, <string.h> and <stdio.h>. * xxlimited_35: Remove Py_mod_multiple_interpreters slot, incompatible with limited C API version 3.5.
* gh-106320: Remove private _PyModule API (#107070)Victor Stinner2023-07-221-11/+0
| | | | | | | | | | | Move private _PyModule API to the internal C API (pycore_moduleobject.h): * _PyModule_Clear() * _PyModule_ClearDict() * _PyModuleSpec_IsInitializing() * _PyModule_IsExtension() No longer export these functions.
* 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).
* gh-104108: Add the Py_mod_multiple_interpreters Module Def Slot (gh-104148)Eric Snow2023-05-051-1/+6
| | | I'll be adding a value to indicate support for per-interpreter GIL in gh-99114.
* gh-81057: Move the Extension Modules Cache to _PyRuntimeState (gh-99355)Eric Snow2022-11-111-0/+14
| | | | | We also move the closely related max_module_number and add comments documenting the group of struct members. https://github.com/python/cpython/issues/81057

* bpo-45459: C API uses type names rather than structure names (GH-31528)Victor Stinner2022-02-241-3/+4
| | | | Thanks to the new pytypedefs.h, it becomes to use type names like PyObject rather like structure names like "struct _object".
* bpo-45459: Add pytypedefs.h header file (GH-31527)Victor Stinner2022-02-241-2/+2
| | | | | | | | | | | | | | | | | | 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-42923: Dump extension modules on fatal error (GH-24207)Victor Stinner2021-01-181-0/+6
| | | | | | | The Py_FatalError() function and the faulthandler module now dump the list of extension modules on a fatal error. Add _Py_DumpExtensionModules() and _PyModule_IsExtension() internal functions.
* bpo-39573: Add Py_IS_TYPE() function (GH-18488)Dong-hee Na2020-02-131-1/+1

* PEP 489: Multi-phase extension module initializationNick Coghlan2015-05-231-1/+15
| | | | | | | | | | | | | | | | | | | | | | | Known limitations of the current implementation: - documentation changes are incomplete - there's a reference leak I haven't tracked down yet The leak is most visible by running: ./python -m test -R3:3 test_importlib However, you can also see it by running: ./python -X showrefcount Importing the array or _testmultiphase modules, and then deleting them from both sys.modules and the local namespace shows significant increases in the total number of active references each cycle. By contrast, with _testcapi (which continues to use single-phase initialisation) the global refcounts stabilise after a couple of cycles.

* Add const to several API functions that take char *.Jeremy Hylton2005-12-101-1/+1
| | | | | | | | | | | | | | | | | | | In C++, it's an error to pass a string literal to a char* function without a const_cast(). Rather than require every C++ extension module to put a cast around string literals, fix the API to state the const-ness. I focused on parts of the API where people usually pass literals: PyArg_ParseTuple() and friends, Py_BuildValue(), PyMethodDef, the type slots, etc. Predictably, there were a large set of functions that needed to be fixed as a result of these changes. The most pervasive change was to make the keyword args list passed to PyArg_ParseTupleAndKewords() to be a const char *kwlist[]. One cast was required as a result of the changes: A type object mallocs the memory for its tp_doc slot and later frees it. PyTypeObject says that tp_doc is const char *; but if the type was created by type_new(), we know it is safe to cast to char *.
