* 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-106320: Remove private _PyLong_Sign() (#108743)Victor Stinner2023-09-011-0/+1
| | | | | | Move the private _PyLong_Sign() and _PyLong_NumBits() functions to the internal C API (pycore_long.h). Modules/_testcapi/long.c now uses the internal C API.
* gh-106320: Remove private _PyErr_ChainExceptions() (#108713)Victor Stinner2023-08-311-0/+1
| | | | | | | | | | | | | Remove _PyErr_ChainExceptions(), _PyErr_ChainExceptions1() and _PyErr_SetFromPyStatus() functions from the public C API. * Move the private _PyErr_ChainExceptions() and _PyErr_ChainExceptions1() function to the internal C API (pycore_pyerrors.h). * Move the private _PyErr_SetFromPyStatus() to the internal C API (pycore_initconfig.h). * No longer export the _PyErr_ChainExceptions() function. * Move run_in_subinterp_with_config() from _testcapi to _testinternalcapi.
* gh-106320: Remove private AC converter functions (#108505)Victor Stinner2023-08-261-0/+1
| | | | | | | | | | | | | | Move these private functions to the internal C API (pycore_abstract.h): * _Py_convert_optional_to_ssize_t() * _PyNumber_Index() Argument Clinic now emits #include "pycore_abstract.h" when these functions are used. The parser of the c-analyzer tool now uses a list of files which use the limited C API, rather than a list of files using the internal C API.
* gh-106320: Remove private PyLong C API functions (#108429)Victor Stinner2023-08-241-2/+3
| | | | | | | | | | | | | | | | Remove private PyLong C API functions: * _PyLong_AsByteArray() * _PyLong_DivmodNear() * _PyLong_Format() * _PyLong_Frexp() * _PyLong_FromByteArray() * _PyLong_FromBytes() * _PyLong_GCD() * _PyLong_Lshift() * _PyLong_Rshift() Move these functions to the internal C API. No longer export _PyLong_FromBytes() function.

* gh-94673: Properly Initialize and Finalize Static Builtin Types for Each ↵Eric Snow2023-05-021-6/+2
| | | | | Interpreter (gh-104072) Until now, we haven't been initializing nor finalizing the per-interpreter state properly.
* gh-94673: Ensure Builtin Static Types are Readied Properly (gh-103940)Eric Snow2023-04-271-6/+4
| | | There were cases where we do unnecessary work for builtin static types. This also simplifies some work necessary for a per-interpreter GIL.

* gh-94673: Isolate the _io module to Each Interpreter (gh-102663)Eric Snow2023-03-211-8/+32
| | | | | Aside from sys and builtins, _io is the only core builtin module that hasn't been ported to multi-phase init. We may do so later (e.g. gh-101948), but in the meantime we must at least take care of the module's static types properly. (This came up while working on gh-101660.) https://github.com/python/cpython/issues/94673
* gh-102255: Improve build support for Windows API partitions (GH-102256)Max Bachmann2023-03-091-3/+3
| | | | | Add `MS_WINDOWS_DESKTOP`, `MS_WINDOWS_APPS`, `MS_WINDOWS_SYSTEM` and `MS_WINDOWS_GAMES` preprocessor definitions to allow switching off functionality missing from particular API partitions ("partitions" are used in Windows to identify overlapping subsets of APIs). CPython only officially supports `MS_WINDOWS_DESKTOP` and `MS_WINDOWS_SYSTEM` (APPS is included by normal desktop builds, but APPS without DESKTOP is not covered). Other configurations are a convenience for people building their own runtimes. `MS_WINDOWS_GAMES` is for the Xbox subset of the Windows API, which is also available on client OS, but is restricted compared to `MS_WINDOWS_DESKTOP`. These restrictions may change over time, as they relate to the build headers rather than the OS support, and so we assume that Xbox builds will use the latest available version of the GDK.

* bpo-15999: Accept arbitrary values for boolean parameters. (#15609)Serhiy Storchaka2022-12-031-8/+7
| | | builtins and extension module functions and methods that expect boolean values for parameters now accept any Python object rather than just a bool or int type. This is more consistent with how native Python code itself behaves.

* bpo-46541: Replace core use of _Py_IDENTIFIER() with statically initialized ↵Eric Snow2022-02-081-9/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | global objects. (gh-30928) We're no longer using _Py_IDENTIFIER() (or _Py_static_string()) in any core CPython code. It is still used in a number of non-builtin stdlib modules. The replacement is: PyUnicodeObject (not pointer) fields under _PyRuntimeState, statically initialized as part of _PyRuntime. A new _Py_GET_GLOBAL_IDENTIFIER() macro facilitates lookup of the fields (along with _Py_GET_GLOBAL_STRING() for non-identifier strings). https://bugs.python.org/issue46541#msg411799 explains the rationale for this change. The core of the change is in: * (new) Include/internal/pycore_global_strings.h - the declarations for the global strings, along with the macros * Include/internal/pycore_runtime_init.h - added the static initializers for the global strings * Include/internal/pycore_global_objects.h - where the struct in pycore_global_strings.h is hooked into _PyRuntimeState * Tools/scripts/generate_global_objects.py - added generation of the global string declarations and static initializers I've also added a --check flag to generate_global_objects.py (along with make check-global-objects) to check for unused global strings. That check is added to the PR CI config. The remainder of this change updates the core code to use _Py_GET_GLOBAL_IDENTIFIER() instead of _Py_IDENTIFIER() and the related _Py*Id functions (likewise for _Py_GET_GLOBAL_STRING() instead of _Py_static_string()). This includes adding a few functions where there wasn't already an alternative to _Py*Id(), replacing the _Py_Identifier * parameter with PyObject *. The following are not changed (yet): * stop using _Py_IDENTIFIER() in the stdlib modules * (maybe) get rid of _Py_IDENTIFIER(), etc. entirely -- this may not be doable as at least one package on PyPI using this (private) API * (maybe) intern the strings during runtime init https://bugs.python.org/issue46541
* bpo-46417: Clear _io module static objects at exit (GH-30807)Victor Stinner2022-01-221-44/+93
| | | | Add _PyIO_Fini() function, called by finalize_interp_clear(). It clears static objects used by the _io extension module.
* bpo-37330: open() no longer accept 'U' in file mode (GH-28118)Victor Stinner2021-09-021-23/+2
| | | | | open(), io.open(), codecs.open() and fileinput.FileInput no longer accept "U" ("universal newline") in the file mode. This flag was deprecated since Python 3.3.
* bpo-43510: Fix emitting EncodingWarning from _io module. (GH-25146)Inada Naoki2021-04-021-2/+4

| | | | | | | | | | | See [PEP 597](https://www.python.org/dev/peps/pep-0597/). * Add `-X warn_default_encoding` and `PYTHONWARNDEFAULTENCODING`. * Add EncodingWarning * Add io.text_encoding() * open(), TextIOWrapper() emits EncodingWarning when encoding is omitted and warn_default_encoding is enabled. * _pyio.TextIOWrapper() uses UTF-8 as fallback default encoding used when failed to import locale module. (used during building Python) * bz2, configparser, gzip, lzma, pathlib, tempfile modules use io.text_encoding(). * What's new entry
* bpo-42208: Add _Py_GetLocaleEncoding() (GH-23050)Victor Stinner2020-10-311-25/+0
| | | | | | | | _io.TextIOWrapper no longer calls getpreferredencoding(False) of _bootlocale to get the locale encoding, but calls _Py_GetLocaleEncoding() instead. Add config_get_fs_encoding() sub-function. Reorganize also config_get_locale_encoding() code.

* bpo-40792: Make the result of PyNumber_Index() always having exact type int. ↵Serhiy Storchaka2020-05-281-1/+1
| | | | | | | | | | | | (GH-20443) Previously, the result could have been an instance of a subclass of int. Also revert bpo-26202 and make attributes start, stop and step of the range object having exact type int. Add private function _PyNumber_Index() which preserves the old behavior of PyNumber_Index() for performance to use it in the conversion functions like PyLong_AsLong().
* bpo-40268: Remove unused structmember.h includes (GH-19530)Victor Stinner2020-04-151-1/+0
| | | | | | If only offsetof() is needed: include stddef.h instead. When structmember.h is used, add a comment explaining that PyMemberDef is used.
* bpo-40268: Add _PyInterpreterState_GetConfig() (GH-19492)Victor Stinner2020-04-131-2/+1
| | | | | | | | Don't access PyInterpreterState.config member directly anymore, but use new functions: * _PyInterpreterState_GetConfig() * _PyInterpreterState_SetConfig() * _Py_GetConfig()
* bpo-40024: Update C extension modules to use PyModule_AddType() (GH-19119)Dong-hee Na2020-03-241-20/+16
