* gh-116322: Add Py_mod_gil module slot (#116882)Brett Simmers2024-05-031-2/+3
| | | | | | | | | | | | | | 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-110968: Py_MOD_PER_INTERPRETER_GIL_SUPPORTED new in 3.13. (#110969)Victor Stinner2023-10-171-2/+3
| | | | | | | | | | * 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-85283: Build errno and _ctypes_test with limited C API (#110955)Victor Stinner2023-10-171-32/+35
| | | _testimportmultiple is now built with limited C API version 3.2.
* gh-105375: Improve errnomodule error handling (#105590)Erlend E. Aasland2023-06-091-3/+5

* 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-102255: Improve build support for Windows API partitions (GH-102256)Max Bachmann2023-03-091-0/+2
| | | | | 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.
* gh-96005: Handle WASI ENOTCAPABLE in getpath (GH-96006)Christian Heimes2022-08-161-0/+4
| | | | | | - On WASI `ENOTCAPABLE` is now mapped to `PermissionError`. - The `errno` modules exposes the new error number. - `getpath.py` now ignores `PermissionError` when it cannot open landmark files `pybuilddir.txt` and `pyenv.cfg`.
* gh-95174: Handle missing dup() and constants in WASI (GH-95229)Christian Heimes2022-07-261-0/+4
| | | | | | | - check for ``dup()`` libc function - handle missing ``F_DUPFD`` in ``dup2()`` replacement function - add workaround for WASI libc bug in MSG_TRUNC - ESHUTDOWN is missing, use EPIPE instead - POLLPRI is missing, define as 0 (no-op)

| | | | | | | | | | | | | | | Py_FatalError() from module initialization functions. The importing mechanism already checks for PyErr_Occurred() after module importation and it Does The Right Thing.

* Bunch of minor ANSIfications: 'void initfunc()' -> 'void initfunc(void)',Thomas Wouters2000-07-211-1/+1
| | | | | | | | | | | | | | | | | | and a couple of functions that were missed in the previous batches. Not terribly tested, but very carefully scrutinized, three times. All these were found by the little findkrc.py that I posted to python-dev, which means there might be more lurking. Cases such as this: long func(a, b) long a; long b; /* flagword */ { and other cases where the last ; in the argument list isn't followed by a newline and an opening curly bracket. Regexps to catch all are welcome, of course ;)
