bpo-30555: Fix WindowsConsoleIO fails in the presence of fd redirection (GH-1927)

2021-04-23T22:00:27+00:00

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)

2021-04-02T08:38:59+00:00

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 (GH-25103)" (#25108)

2021-03-31T09:49:41+00:00

This reverts commit ff3c9739bd69aa8b58007e63c9e40e6708b4761e.

bpo-43510: PEP 597: Accept `encoding="locale"` in binary mode (GH-25103)

2021-03-31T05:26:08+00:00

It make `encoding="locale"` usable everywhere `encoding=None` is
allowed.

bpo-43510: Implement PEP 597 opt-in EncodingWarning. (GH-19481)

2021-03-29T03:28:14+00:00

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)

2021-02-21T23:29:30+00:00

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.

bpo-42236: Enhance _locale._get_locale_encoding() (GH-23083)

2020-11-01T19:59:35+00:00

* 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)

2020-10-31T00:02:09+00:00

_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)

2020-10-27T16:12:53+00:00

Use _PyLong_GetZero() and _PyLong_GetOne() in Modules/ directory.

_cursesmodule.c and zoneinfo.c are now built with
Py_BUILD_CORE_MODULE macro defined.
