* bpo-46222: posixmodule sendfile FreeBSD's constants updates. (GH-30327)David CARLIER2022-01-031-0/+4
| | | | | | | * posixodule sendfile FreeBSD's constants updates. * 📜🤖 Added by blurb_it. Co-authored-by: blurb-it[bot] <43283697+blurb-it[bot]@users.noreply.github.com>

* bpo-46008: Add _PyInterpreterState_Main(). (gh-29978)Eric Snow2021-12-081-2/+2
| | | | | PyInterpreterState_Main() is a plain function exposed in the public C-API. For internal usage we can take the more efficient approach in this PR. https://bugs.python.org/issue46008
* 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.

* bpo-45434: pyport.h no longer includes <stdlib.h> (GH-28914)Victor Stinner2021-10-131-1/+2
| | | | | Include <stdlib.h> explicitly in C files. Python.h includes <wchar.h>.
* 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-44321: Adds `os.EX_OK` for Windows (GH-26559)Samuel Marks2021-06-241-0/+4
|
* 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.
* bpo-43538: Add extra arguments to os.startfile (GH-25538)Steve Dower2021-04-231-3/+22
|
* bpo-38222: Check specifically for a drive, not just a colon (GH-25540)Steve Dower2021-04-221-2/+2
|
* bpo-38822: Fixed os.stat failing on inaccessible directories. (GH-25527)Steve Dower2021-04-221-2/+21
| | | 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.

* bpo-42692: fix __builtin_available check on older compilers (GH-23873)Joshua Root2021-01-041-1/+7
| | | | | | A compiler that doesn't define `__has_builtin` will error out when it is used on the same line as the check for it. Automerge-Triggered-By: GH:ronaldoussoren

* bpo-42519: Replace PyMem_MALLOC() with PyMem_Malloc() (GH-23586)Victor Stinner2020-12-011-15/+16
| | | | | | | | | | | No longer use deprecated aliases to functions: * Replace PyMem_MALLOC() with PyMem_Malloc() * Replace PyMem_REALLOC() with PyMem_Realloc() * Replace PyMem_FREE() with PyMem_Free() * Replace PyMem_Del() with PyMem_Free() * Replace PyMem_DEL() with PyMem_Free() Modify also the PyMem_DEL() macro to use directly PyMem_Free().
* bpo-1635741: Convert _imp to multi-phase init (GH-23378)Victor Stinner2020-11-181-1/+1
| | | | | | | | | | | | Convert the _imp extension module to the multi-phase initialization API (PEP 489). * Add _PyImport_BootstrapImp() which fix a bootstrap issue: import the _imp module before importlib is initialized. * Add create_builtin() sub-function, used by _imp_create_builtin(). * Initialize PyInterpreterState.import_func earlier, in pycore_init_builtins(). * Remove references to _PyImport_Cleanup(). This function has been renamed to finalize_modules() and moved to pylifecycle.c.
* bpo-41625: Add a guard for Linux for splice() constants in the os module ↵Pablo Galindo2020-11-171-1/+1

* bpo-41100: Support macOS 11 and Apple Silicon (GH-22855)Ronald Oussoren2020-11-081-175/+647
| | | | | | | | | | | Co-authored-by: Lawrence D’Anna <lawrence_danna@apple.com> * Add support for macOS 11 and Apple Silicon (aka arm64) As a side effect of this work use the system copy of libffi on macOS, and remove the vendored copy * Support building on recent versions of macOS while deploying to older versions This allows building installers on macOS 11 while still supporting macOS 10.9.
* bpo-42029: Remove IRIX code (GH-23023)Victor Stinner2020-10-291-4/+3
| | | | IRIX code was slowy removed in Python 2.4 (--with-sgi-dl), Python 3.3 (Irix threads), and Python 3.7.
* bpo-42152: Use PyDict_Contains and PyDict_SetDefault if appropriate. (GH-22986)Serhiy Storchaka2020-10-261-7/+5
| | | | | | | If PyDict_GetItemWithError is only used to check whether the key is in dict, it is better to use PyDict_Contains instead. And if it is used in combination with PyDict_SetItem, PyDict_SetDefault can replace the combination.
* bpo-40422: Move _Py_closerange to fileutils.c (GH-22680)Kyle Evans2020-10-131-76/+1
| | | | | | | This API is relatively lightweight and organizationally, given that it's used by multiple modules, it makes sense to move it to fileutils. Requires making sure that _posixsubprocess is compiled with the appropriate Py_BUIILD_CORE_BUILTIN macro.
* bpo-40422: Move _Py_*_SUPPRESS_IPH bits into _Py_closerange (GH-22672)Kyle Evans2020-10-121-2/+2
| | | | | | This suppression is no longer needed in os_closerange_impl, as it just invokes the internal _Py_closerange implementation. On the other hand, consumers of _Py_closerange may not have any other reason to suppress invalid parameter issues, so narrow the scope to here.
* bpo-40423: Optimization: use close_range(2) if available (GH-22651)Kyle Evans2020-10-111-3/+14
| | | | | | | close_range(2) should be preferred at all times if it's available, otherwise we'll use closefrom(2) if available with a fallback to fdwalk(3) or plain old loop over fd range in order of most efficient to least. [note that this version does check for ENOSYS, but currently ignores all other errors] Automerge-Triggered-By: @pablogsal
* bpo-40422: create a common _Py_closerange API (GH-19754)Kyle Evans2020-10-111-24/+46
| | | | | | | Such an API can be used both for os.closerange and subprocess. For the latter, this yields potential improvement for platforms that have fdwalk but wouldn't have used it there. This will prove even more beneficial later for platforms that have close_range(2), as the new API will prefer that over all else if it's available. The new API is structured to look more like close_range(2), closing from [start, end] rather than the [low, high) of os.closerange(). Automerge-Triggered-By: @gpshead

* bpo-41687: Fix error handling in Solaris sendfile implementation (GH-22128)Jakub Kulík2020-09-091-3/+2
| | | | | | | I just realized that my recent PR with sendfile on Solaris ([PR 22040](https://github.com/python/cpython/pull/22040)) has broken error handling. Sorry for that, this simple followup fixes that. Automerge-Triggered-By: @1st1

* bpo-36346: Make using the legacy Unicode C API optional (GH-21437)Serhiy Storchaka2020-07-101-9/+61
| | | | Add compile time option USE_UNICODE_WCHAR_CACHE. Setting it to 0 makes the interpreter not using the wchar_t cache and the legacy Unicode C API.
* bpo-41056: Use the fildes converter for fd to please Coverity. (GH-21011)Gregory P. Smith2020-06-201-2/+2
| | | | | | | | | There are a bunch of other fd: int uses in this file, I expect many if not all of them would be better off using the fildes converter. This particular one was flagged by Coverity as it presumably flags fpathconf as not accepting negative fds. I'd expect the other fd's to have been flagged as well otherwise. I'm marking this one as skip news as it really is a no-op.
* PyOS_AfterFork_Child() pass tstate to _PyEval_ReInitThreads() (GH-20598)Victor Stinner2020-06-021-2/+6
|
* PyOS_AfterFork_Child() uses PyStatus (GH-20596)Victor Stinner2020-06-021-5/+32
| | | | | | | | PyOS_AfterFork_Child() helper functions now return a PyStatus: PyOS_AfterFork_Child() is now responsible to handle errors. * Move _PySignal_AfterFork() to the internal C API * Add #ifdef HAVE_FORK on _PyGILState_Reinit(), _PySignal_AfterFork() and _PyInterpreterState_DeleteExceptMain().
* bpo-40792: Make the result of PyNumber_Index() always having exact type int. ↵Serhiy Storchaka2020-05-281-3/+3
| | | | | | | | | | | | (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-37129: Add os.RWF_APPEND flag for os.pwritev() (GH-20336)YoSTEALTH2020-05-271-1/+5

* bpo-37999: No longer use __int__ in implicit integer conversions. (GH-15636)Serhiy Storchaka2020-05-261-5/+0
