| | | | | | | when the underlying file is closed (GH-28457) (cherry picked from commit a450398933d265011e1e8eae7f771b70f97945fb) Co-authored-by: AngstyDuck <solsticedante@gmail.com>
* 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
| | | | | (GH-25103)" (#25108) This reverts commit ff3c9739bd69aa8b58007e63c9e40e6708b4761e.
* 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.
* bpo-40268: Add _PyInterpreterState_GetConfig() (GH-19492)Victor Stinner2020-04-133-5/+4
| | | | | | | | Don't access PyInterpreterState.config member directly anymore, but use new functions: * _PyInterpreterState_GetConfig() * _PyInterpreterState_SetConfig() * _Py_GetConfig()
* bpo-39943: Add the const qualifier to pointers on non-mutable PyBytes data. ↵Serhiy Storchaka2020-04-122-3/+3
| | | | (GH-19472)

* bpo-40024: Update C extension modules to use PyModule_AddType() (GH-19119)Dong-hee Na2020-03-241-20/+16
| | | | | | Update _asyncio, _bz2, _csv, _curses, _datetime, _io, _operator, _pickle, _queue, blake2, multibytecodec and overlapped C extension modules to use PyModule_AddType().
* bpo-39968: Convert extension modules' macros of get_module_state() to inline ↵Hai Shi2020-03-161-4/+11
| | | | functions (GH-19017)
* bpo-39674: Revert "bpo-37330: open() no longer accept 'U' in file mode ↵Victor Stinner2020-03-042-3/+29
| | | | | | | (GH-16959)" (GH-18767) This reverts commit e471e72977c83664f13d041c78549140c86c92de. The mode will be removed from Python 3.10.

* closes bpo-39605: Fix some casts to not cast away const. (GH-18453)Andy Lester2020-02-121-2/+2
| | | | | | | | | | | | | | | gcc -Wcast-qual turns up a number of instances of casting away constness of pointers. Some of these can be safely modified, by either: Adding the const to the type cast, as in: - return _PyUnicode_FromUCS1((unsigned char*)s, size); + return _PyUnicode_FromUCS1((const unsigned char*)s, size); or, Removing the cast entirely, because it's not necessary (but probably was at one time), as in: - PyDTrace_FUNCTION_ENTRY((char *)filename, (char *)funcname, lineno); + PyDTrace_FUNCTION_ENTRY(filename, funcname, lineno); These changes will not change code, but they will make it much easier to check for errors in consts
* bpo-39245: Switch to public API for Vectorcall (GH-18460)Petr Viktorin2020-02-114-45/+45

* closes bpo-39510: Fix use-after-free in BufferedReader.readinto() (GH-18295)Philipp Gesang2020-02-041-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | When called on a closed object, readinto() segfaults on account of a write to a freed buffer: ==220553== Process terminating with default action of signal 11 (SIGSEGV): dumping core ==220553== Access not within mapped region at address 0x2A ==220553== at 0x48408A0: memmove (vg_replace_strmem.c:1272) ==220553== by 0x58DB0C: _buffered_readinto_generic (bufferedio.c:972) ==220553== by 0x58DCBA: _io__Buffered_readinto_impl (bufferedio.c:1053) ==220553== by 0x58DCBA: _io__Buffered_readinto (bufferedio.c.h:253) Reproducer: reader = open ("/dev/zero", "rb") _void = reader.read (42) reader.close () reader.readinto (bytearray (42)) ### BANG!

* closes bpo-27805: Ignore ESPIPE in initializing seek of append-mode files. ↵Benjamin Peterson2019-11-121-9/+15
| | | | | (GH-17112) This change, which follows the behavior of C stdio's fdopen and Python 2's file object, allows pipes to be opened in append mode.
* bpo-37330: open() no longer accept 'U' in file mode (GH-16959)Victor Stinner2019-10-282-29/+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.
