* [3.11] gh-97897: Prevent os.mkfifo and os.mknod segfaults with macOS 13 SDK ↵Miss Islington (bot)2022-10-061-8/+52
| | | | | | | | | | | | | (GH-97944) (#97969) The macOS 13 SDK includes support for the `mkfifoat` and `mknodat` system calls. Using the `dir_fd` option with either `os.mkfifo` or `os.mknod` could result in a segfault if cpython is built with the macOS 13 SDK but run on an earlier version of macOS. Prevent this by adding runtime support for detection of these system calls ("weaklinking") as is done for other newer syscalls on macOS.

* bpo-46541: Replace core use of _Py_IDENTIFIER() with statically initialized ↵Eric Snow2022-02-081-6/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | 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-45582: Port getpath[p].c to Python (GH-29041)Steve Dower2021-12-031-0/+28
| | | | | The getpath.py file is frozen at build time and executed as code over a namespace. It is never imported, nor is it meant to be importable or reusable. However, it should be easier to read, modify, and patch than the previous code. This commit attempts to preserve every previously tested quirk, but these may be changed in the future to better align platforms.

* pycore_pystate.h no longer redefines PyThreadState_GET() (GH-28921)Victor Stinner2021-10-131-13/+11
| | | | | | | | | | | | | | | | | | | | | | Redefining the PyThreadState_GET() macro in pycore_pystate.h is useless since it doesn't affect files not including it. Either use _PyThreadState_GET() directly, or don't use pycore_pystate.h internal C API. For example, the _testcapi extension don't use the internal C API, but use the public PyThreadState_Get() function instead. Replace PyThreadState_Get() with _PyThreadState_GET(). The _PyThreadState_GET() macro is more efficient than PyThreadState_Get() and PyThreadState_GET() function calls which call fail with a fatal Python error. posixmodule.c and _ctypes extension now include <windows.h> before pycore header files (like pycore_call.h). _PyTraceback_Add() now uses _PyErr_Fetch()/_PyErr_Restore() instead of PyErr_Fetch()/PyErr_Restore(). The _decimal and _xxsubinterpreters extensions are now built with the Py_BUILD_CORE_MODULE macro defined to get access to the internal C API.
* bpo-45439: Move _PyObject_CallNoArgs() to pycore_call.h (GH-28895)Victor Stinner2021-10-121-1/+2
| | | | | | | * Move _PyObject_CallNoArgs() to pycore_call.h (internal C API). * _ssl, _sqlite and _testcapi extensions now call the public PyObject_CallNoArgs() function, rather than _PyObject_CallNoArgs(). * _lsprof extension is now built with Py_BUILD_CORE_MODULE macro defined to get access to internal _PyObject_CallNoArgs().
* bpo-45439: Rename _PyObject_CallNoArg() to _PyObject_CallNoArgs() (GH-28891)Victor Stinner2021-10-111-3/+3
| | | | | Fix typo in the private _PyObject_CallNoArg() function name: rename it to _PyObject_CallNoArgs() to be consistent with the public function PyObject_CallNoArgs().
* Clean up initialization __class_getitem__ with Py_GenericAlias. (GH-28450)Serhiy Storchaka2021-09-191-1/+1
| | | | | The cast to PyCFunction is redundant. Overuse of redundant casts can hide actual bugs.
* bpo-44219: Release the GIL during isatty syscalls (GH-28250)Vincent Michel2021-09-091-0/+2
| | | | | | Release the GIL while performing isatty() system calls on arbitrary file descriptors. In particular, this affects os.isatty(), os.device_encoding() and io.TextIOWrapper. By extension, io.open() in text mode is also affected.
* bpo-45012: Release GIL around stat in os.scandir (GH-28085)Stanisław Skonieczny2021-09-071-2/+8
| | | | | Releasing GIL allows other threads to continue its work when os.scandir is fetching DirEntry.stat info from file system.

* bpo-43916: Remove _disabled_new() function (GH-25745)Victor Stinner2021-04-301-12/+3
| | | | | posix and _hashlib use the new Py_TPFLAGS_DISALLOW_INSTANTIATION flag on their heap types, rather than using a custom tp_new function (_disabled_new).
* bpo-30555: Fix WindowsConsoleIO fails in the presence of fd redirection ↵Segev Finer2021-04-231-4/+2
| | | | | | | | (GH-1927) This works by not caching the handle and instead getting the handle from the file descriptor each time, so that if the actual handle changes by fd redirection closing/opening the console handle beneath our feet, we will keep working correctly.

| | | It would just fail if the path was inaccessible and had a trailing slash. It should fall back to the parent directory's metadata.
* bpo-40137: Add pycore_moduleobject.h internal header (GH-25507)Victor Stinner2021-04-211-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add pycore_moduleobject.h internal header file with static inline functions to access module members: * _PyModule_GetDict() * _PyModule_GetDef() * _PyModule_GetState() These functions don't check at runtime if their argument has a valid type and can be inlined even if Python is not built with LTO. _PyType_GetModuleByDef() uses _PyModule_GetDef(). Replace PyModule_GetState() with _PyModule_GetState() in the extension modules, considered as performance sensitive: * _abc * _functools * _operator * _pickle * _queue * _random * _sre * _struct * _thread * _winapi * array * posix The following extensions are now built with the Py_BUILD_CORE_MODULE macro defined, to be able to use the internal pycore_moduleobject.h header: _abc, array, _operator, _queue, _sre, _struct.

This function has been renamed to finalize_modules() and moved to pylifecycle.c.
