* bpo-46541: Replace core use of _Py_IDENTIFIER() with statically initialized ↵Eric Snow2022-02-086-160/+102
| | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
* Remove unused variables. (GH-29231)Benjamin Peterson2021-10-261-5/+1

* bpo-45439: Move _PyObject_CallNoArgs() to pycore_call.h (GH-28895)Victor Stinner2021-10-121-0/+1
| | | | | | | * 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 Stinner2021-10-111-1/+1
| | | | | Fix typo in the private _PyObject_CallNoArg() function name: rename it to _PyObject_CallNoArgs() to be consistent with the public function PyObject_CallNoArgs().
* bpo-44687: Ensure BufferedReader objects with unread buffers can peek even ↵AngstyDuck2021-10-011-3/+5

* bpo-43413: Fix handling keyword arguments in subclasses of some buitin ↵Serhiy Storchaka2021-09-121-2/+3
| | | | | | | | classes (GH-26456) * Constructors of subclasses of some buitin classes (e.g. tuple, list, frozenset) no longer accept arbitrary keyword arguments. * Subclass of set can now define a __new__() method with additional keyword parameters without overriding also __init__().
* bpo-45094: Add Py_NO_INLINE macro (GH-28140)Victor Stinner2021-09-031-1/+1
| | | | | * Rename _Py_NO_INLINE macro to Py_NO_INLINE: make it public and document it. * Sort macros in the C API documentation.
* bpo-37330: open() no longer accept 'U' in file mode (GH-28118)Victor Stinner2021-09-022-29/+3
| | | | | 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-30555: Fix WindowsConsoleIO fails in the presence of fd redirection ↵Segev Finer2021-04-232-73/+73
| | | | | | | | (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-43510: Fix emitting EncodingWarning from _io module. (GH-25146)Inada Naoki2021-04-022-13/+17
| | | I forget to check PyErr_WarnEx() return value. But it will fail when -Werror is used.
* Revert "bpo-43510: PEP 597: Accept `encoding="locale"` in binary mode ↵Inada Naoki2021-03-311-2/+1

* bpo-43510: PEP 597: Accept `encoding="locale"` in binary mode (GH-25103)Inada Naoki2021-03-311-1/+2
| | | | It make `encoding="locale"` usable everywhere `encoding=None` is allowed.
* bpo-43510: Implement PEP 597 opt-in EncodingWarning. (GH-19481)Inada Naoki2021-03-293-1/+99
| | | | | | | | | | | 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-43260: io: Prevent large data remains in textio buffer. (GH-24592)Inada Naoki2021-02-211-3/+17
| | | | | | | | When very large data remains in TextIOWrapper, flush() may fail forever. So prevent that data larger than chunk_size is remained in TextIOWrapper internal buffer. Co-Authored-By: Eryk Sun
* bpo-42236: Enhance _locale._get_locale_encoding() (GH-23083)Victor Stinner2020-11-011-1/+1
| | | | | | | | | * Rename _Py_GetLocaleEncoding() to _Py_GetLocaleEncodingObject() * Add _Py_GetLocaleEncoding() which returns a wchar_t* string to share code between _Py_GetLocaleEncodingObject() and config_get_locale_encoding(). * _Py_GetLocaleEncodingObject() now decodes nl_langinfo(CODESET) from the current locale encoding with surrogateescape, rather than using UTF-8.
* bpo-42208: Add _Py_GetLocaleEncoding() (GH-23050)Victor Stinner2020-10-313-48/+4
| | | | | | | | _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-42161: Modules/ uses _PyLong_GetZero() and _PyLong_GetOne() (GH-22998)Victor Stinner2020-10-272-8/+12
| | | | | | Use _PyLong_GetZero() and _PyLong_GetOne() in Modules/ directory. _cursesmodule.c and zoneinfo.c are now built with Py_BUILD_CORE_MODULE macro defined.
* bpo-40170: Use inline _PyType_HasFeature() function (GH-22375)Victor Stinner2020-09-231-1/+2
| | | | | Use _PyType_HasFeature() in the _io module and in structseq implementation. Replace PyType_HasFeature() opaque function call with _PyType_HasFeature() inlined function.
* bpo-36346: Make using the legacy Unicode C API optional (GH-21437)Serhiy Storchaka2020-07-101-0/+12
| | | | 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.
* closes bpo-28557: error message for bad raw readinto (GH-7496)David Szotten2020-06-151-0/+9

* bpo-40792: Make the result of PyNumber_Index() always having exact type int. ↵Serhiy Storchaka2020-05-286-16/+16
| | | | | | | | | | | | (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-37999: No longer use __int__ in implicit integer conversions. (GH-15636)Serhiy Storchaka2020-05-2610-139/+8
| | | | Only __index__ should be used to make integer conversions lossless.
* bpo-40521: Add PyInterpreterState.unicode (GH-20081)Victor Stinner2020-05-131-1/+1
| | | | | | | Move PyInterpreterState.fs_codec into a new PyInterpreterState.unicode structure. Give a name to the fs_codec structure and use this structure in unicodeobject.c.
* bpo-40268: Remove unused structmember.h includes (GH-19530)Victor Stinner2020-04-158-10/+9
| | | | | | If only offsetof() is needed: include stddef.h instead. When structmember.h is used, add a comment explaining that PyMemberDef is used.
* bpo-40268: Remove explicit pythread.h includes (#19529)Victor Stinner2020-04-151-1/+0
| | | | Remove explicit pythread.h includes: it is always included by Python.h.
* bpo-40268: Remove a few pycore_pystate.h includes (GH-19510)Victor Stinner2020-04-142-2/+2
|
* bpo-40268: Rename _PyInterpreterState_GET_UNSAFE() (GH-19509)Victor Stinner2020-04-141-1/+1
| | | | | | | Rename _PyInterpreterState_GET_UNSAFE() to _PyInterpreterState_GET() for consistency with _PyThreadState_GET() and to have a shorter name (help to fit into 80 columns). Add also "assert(tstate != NULL);" to the function.
